Why does the connector fail

The inner conductor of the connector is smaller in size relative to the outer conductor, and the inner conductor having a lower strength is more likely to cause poor contact and cause the connector to fail.

1.The inner conductor is not fixed firmly

For assembly purposes, in many RF coaxial connectors, the inner conductor is divided into two sections at the media support and then threaded. However, due to the small diameter of the inner conductor, if the glue is not fixed at the screw connection during assembly, the strength of the inner conductor connection is very poor, especially for some small RF coaxial connectors.

Therefore, when the connector is connected and disconnected multiple times, under the long-term action of the torque and the pulling force, the inner conductor thread may loosen and fall off, resulting in the connection failure.

2.The size of the inner conductor's jack or pin is incorrect.

If the inner conductor hole diameter of the jack is smaller than the specified size, when the pin of the inner conductor of the pin enters the jack, the jack is excessively expanded, and the shape variable exceeds the elastic deformation range, causing plastic deformation, resulting in damage of the inner conductor of the jack.

On the contrary, if the diameter of the pin is too small, when the pin and the socket are engaged, the gap between the pin and the wall of the jack is too large, the two inner conductors of the connector are not in close contact, the contact resistance becomes large, and the connector is Electrical performance indicators will also be poor.

Waterproof connector, reliability is the key

Waterproof connector, as the name suggests, are reliable power and signal connections based on waterproofing. Because there are a lot of complicated factors in the use environment of electronic equipment, especially under water, there are countless electronic devices working and all need to be waterproof connectors to ensure the normal operation of the equipment. In particular, a large number of waterproof connectors are used in mobile phones, computers, home decorate, medical products, and automobiles, so waterproof connectors have become the fastest growing branch of the connector market.

At present, the waterproof connector is changing from the standard product to the customization direction, from the traditional single signal transmission to the mixed signal transmission (power supply plus signal), from the first function connector to the modularization, intelligent, ultra-small direction. With the requirements for miniaturization, high integration and waterproofness of electronic products are increasing, and the waterproof connector products and connector products are also pushed to the development of small size, low height, narrow pitch, multi-function, long life, surface mounting, etc. Due to the increasing level of waterproofing of electronic products, it is important for product designers to choose a reliable waterproof connector.

Advantages of waterproof connectors

In addition to the waterproof function, it is also resistant to corrosion and high temperature, in order to prevent the acid in some water from corroding the connector.

Anti-electromagnetic interference, because water is a conductor, it prevents electromagnetic interference in the water and interferes with the equipment, affecting its normal operation.

The Injection molding temperature of pin connector is too high

In the process of injection molding, the temperature of the pin connector is a very critical factor, and its level will directly affect the quality of the injection molding process.What happens if the Injection molding temperature of pin connector is too high?The introduction of yeahui is as follows.

First, Thermal deformation of the machine:

The moving parts with different thermal expansion coefficients in the hydraulic components are stuck due to the smaller matching clearance, causing malfunction. It will affect the transmission precision of the hydraulic system, and also affect the working quality of the components.

Second, reduce the viscosity of the oil:

Excessive temperature rise in the injection molding machine will result in lower viscosity of the oil, increased leakage, the volumetric efficiency of the pump and the efficiency of the entire system are significantly reduced. As the viscosity of the oil is lowered, the oil film of the moving parts such as the slide valve is thinned and cut, and the frictional resistance is increased, It will result in an increased wear.

Third, Deform the rubber seal:

In the actual test, it was found that the excessive temperature rise of the injection molding machine would deform the rubber seal, accelerate the aging failure, reduce the sealing performance and service life, and cause leakage.

Fourth, the oxidation and deterioration of the oil:

If the temperature rise of the injection molding machine is too high, it will accelerate the oxidation and deterioration of the oil, precipitate the asphalt material, and reduce the service life of the hydraulic oil. The precipitate blocks the damper orifice and the slit valve port, causing the pressure valve to become stuck and unable to move, the metal pipe to be elongated and bent, or even broken.

Connectors are widely used

Connectors are widely used.Connectors are a component that our electronic engineering technicians often use. Its role is very simple: to bridge the communication between the blocked or isolated circuits, so that the current flows, and the circuit achieves the intended function. Connectors are an indispensable part of an electronic device. You will always find one or more connectors along the current flows.

The form and structure of the connector are ever-changing. There are various types of connectors depending on the application object, frequency, power, and application environment. For example, the connector for lighting on the court and the connector for the hard drive, as well as the connector for igniting the rocket, they are quite different. But no matter what kind of connector, it is necessary to ensure smooth and continuous current flow. In general terms, the connection is not limited to current. In today's rapid development of optoelectronic technology, in the optical fiber system, the carrier which transmits the signal is light, and the glass and plastic replace the wires in the ordinary circuit, but the optical signal connectors are also used in the vias, which function the same as circuit connectors.

What are the basic performance of PCB connector?

Connector is a detachable component (except an adapter) that is usually install on a cable or device for system data transmission or electrical connection, which means connecting two source devices to transmit signals or current. Yeahui introduces you to the basic performance of PCB connectors. The basic performance of PCB connectors can be divided into three main categories:

1.mechanical properties

In terms of the connection function, the insertion force is an important mechanical property. The insertion force is divided into the insertion force and the extraction force, and the requirements of this two parts are different. There is a maximum insertion force and a minimum separation force specification in the relevant standards, which indicates that the insertion force is small , but if the separation force is too small, and the reliability of the contact may be affected. Mechanical life is actually a durability indicator, which is called mechanical operation in GB5095. It is a cycle of one insertion and one extraction to judge whether the PCB connector can complete its connection function normally after the specified insertion and extraction cycle. The insertion and extraction force and mechanical life of the PCB connector are related to the structure of the contact, the quality of the coating at the contact site, and the dimensional accuracy of the contact arrangement.

2.Electrical properties

The main electrical properties of PCB connectors include contact resistance, insulation resistance and electrical strength. High quality electrical PCB connectors should have low and stable contact resistance. The contact resistance of PCB connectors ranges from a few milliohms to tens of milliohms. Insulation resistance is an indicator of the insulation properties between PCB connector contacts and between the contacts and the housing. It ranges from hundreds of megaohms to several gigaohms. The electrical strength is a measure of the ability to withstand the rated test voltage between the PCB connector contacts or between the contacts and the housing.

3. The environmental properties

For RF coaxial PCB connectors, There are also have electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio. Due to the development of digital technology, in order to connect and transmit high-speed digital pulse signals, a new type of PCB connector, namely high-speed signal PCB connector has appeared in the market. Accordingly, in electrical properties, in addition to characteristic impedance. some new electrical indicators have appeared such as crosstalk, transmission delay, time lag, etc.

Above is some relevant contents about PCB connector properties. We hope that through the above content, you can further understand PCB connectors.You can learn more about connectors from the article(When do I need an obd connector).

When do I need an obd connector?

OBD which means on-board automatic diagnosis system. OBD can detect the working condition of the engine electronic control system and other functional modules of the vehicle during the running of the vehicle. By using the OBD interface to connect the car and computer, we can view the car data and detect the car fault at time, which is convenient for auto repair, development of car related functions, and transformation of car equipment. However, the OBD interface can not connect the computer directly, so we need a connector to connect them, that is the OBD connector. Just install the appropriate driver on the computer then you can read the data of the car, such as car speed, Rotating speed, water temperature and so on.

This simple operation can be done by yourself. If the OBD connector is broken, we can also install it by ourselves. Of course, we can go to the repair shop to repair it, but some repair shops may not have OBD connector which suit your car.

What is an OBD Connector?

On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems.

Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.

OBD connector is the connection of vehicle and vehicle subsystem.

Difference between OBD&OBD2

Several automakers introduced computer interfaces for their own cars before the 1990s, but the push to standardize didn’t begin until 1991, when the California Air Resources Board (CARB) mandated that all cars sold in California needed some form of OBD capability. However, CARB didn’t issue standards for the systems until 1994. Known as OBD II, that standard was implemented for the 1996 model year, and is still in use today. Previous iterations of OBD were retroactively classified OBD I.

Virtually every new car sold in the U.S. over the past 20 years follows the OBD II standard. OBD II cars have a port — usually located under the dashboard on the driver’s side — that devices can plug into and connect to a car’s computer. Companies have plenty of ideas about what you can plug into that port.

Cable assembly factory: Potential Risk to Avoid When Packing Terminals

As a custom cable assembly factory, we got numerous range of products. Both your small order and mass quantity can be met.

One of our customer send free-issue connector and terminals. Generally terminal is packed for reel. But they cut 10 terminal's per row. After receiving, the production director feedback this serious problems and request never should send it like that again.

The reason why is terminal crimping processing is a very fast machine and human work, if the terminal is with 10pcs/row, it's dangerous for our workers and low efficiency.

Yeahui take great care for our employees' safety and well being. we thanks a lot for customer's understanding to terminal's minimum order quantity requirement and packing method. Our website:www.obdiicable.com

The Methods to Selecting M8 and M12 Cord Sets

Additional cost reductions come from reduced downtime, as cord sets can easily be replaced, again without need of an electrician. Connectorized sensors and actuators can also be replaced without rewiring the system.

1. Choosing the Right Cord Set – Start with the Environmental Needs

The possible combinations of cables and connectors is a surprisingly high number. Where do you even start the specification process?

Like most engineering decisions, there’s a balance between cost and performance. You want to choose the lowest cost option that meets the requirements of the application. For example, you don’t need armored cable if it is going to be run in wire trays in a temperature- and humidity-controlled environment.

Thus the first question to ask yourself is “How harsh is the environment for my project?” The answer to this leads to selecting the right industrial cable jacket and the right IP rating for the cord set. Below is a handy table that breaks down the options according to the harshness of the operational setting.

2. Determine the Connector Configurations

Since the introduction of the 3- and 4-pin versions of the M12 connector, many more variations and options have become available. While 4-pin M12 connectors are the most common, be sure to analyze your application and choose from:

straight or right angle configurations 3-, 4-, 5-, 8- and 12-pin versions

For M8 connectors your options are:

Straight or right angle configurations Snap(IP65) or screw connection (IP67) 3-, 4- and 8-pin versions

3. Select the Keying Options

The M12 connector is also available in a variety of keying/coding options to further minimize wiring errors as follows:

A-code – Primarily used with sensors and actuators B-code – PROFIBUS fieldbus connections C-code (dual keyway) – Primarily used with AC sensors and actuators D-code – 100Mb EtherNet/IP 4-pin X-code – Gigabit Ethernet 8-pin

The following M8 connector configurations feature a keying/coding:

B-code – PROFIBUS fieldbus connections 8-pin version

make OBD2 Extension Cable

Using OBD2 extension cable can save the wear and tear on your scan tool’s OBD connector . Obd2 cables often overlooked part of any electrical system .Building a quality obd2 extension cable requires a couple inexpensive tools and the right techniques .

Here Yeahui have some tips to make obd2 extension cable :

1. To cut each wire to length and strip the ends .

2. To crimp a terminal on each end . Tug on each terminal to ensure there is no movement of the wire .

3. Please repeat steps 1 and 2 for each wire , securing it to the template as it would be in the finished harness .

4. To Test continuity of all wires and verify routing .

5. To install heat shrink or loom , moving from the “small” end of the harness to the “big” end . For heat shrink , overlap between sections will help keep moisture out and keep the harness from coming apart .

6. To check continuity of each wire . For multi-pin connectors , make sure you know which terminal needs to go where in the housing , they can be a pain to remove if you screw up .

7. To install connector housings . Done !

High quality materials give the cable superior flexibility and durability . If you think it is difficult to make the obd2 cable , you could contact Yeahui (one of the earlier bird in electrical interconnect market )to buy a new one : www.obdiicable.com
