Design reliability of the connector

Connectors are important components of various electrical systems and are mainly responsible for signal and power transmission. The importance is self-evident, so we need to put their reliability first when designing connectors. So where does the design reliability of the connector manifest itself?

Reasonable selection

Material selection is an important prerequisite to ensure the electrical performance and reliability of the electrical connector. The material used in the electrical connector determines the upper limit of the operating temperature, and the decisive factor is the insulating material, the sealing material used for the environmentally sealed electrical connector, the adhesive material, the shell Body and contact materials. Material selection involves the mechanical, electrical, environmental and other performance requirements of the connector and the physical and chemical properties of the material itself. Among them, the thermal properties of materials (heat-resistant temperature, thermal conductivity, high-temperature strength, thermal deformation, etc.) are the main factors that must be considered in the design. Electrical connector insulators are made of different insulating materials, and their electrical properties such as insulation and voltage resistance are also significantly different. In selecting electrical connector housings and contacts, in addition to considering conductivity, thermal conductivity, and structural rigidity, the electrochemical compatibility and hardness matching of the mating and contact materials should also be considered.

Structure of the connector

The structure of the connector is an important factor that determines the reliability of the product. A reasonable structure not only avoids errors, but also improves the stability of the structure. The confidential connection between the system and the connector can prevent signal and power loss. Therefore, when designing the connector, you must also consider the fixation of the connector to prevent the connector from falling off.

What to pay attention to when producing terminal connectors

The current terminal connector applications are very common, especially in the industrial field. Different types of terminal connectors have different application requirements. There are also factors that need to be kept in mind when producing terminal connectors.

You should know that the terminal is an accessory product for industrial production of electrical components. Its main function is to facilitate the connection of wires. Therefore, it is also divided into the scope of connectors in the process of industrial development, and it also becomes a terminal connector, which means that it functions An important part of industrial production plays the role of a connector, which is not only convenient for production, but also conducive to improving production efficiency as the main purpose.

In addition, according to the process of industrialization, wire connections and signal transmission have already been realized. But how can the transmission process be guaranteed? That is the purpose of designing the terminal, that is, the important role of the terminal connector.

It should be noted that the terminal connector mainly completes the transmission task by the tightness of the connection of the terminal itself on the mother body. The degree of combination of the terminal inserted into the mother body and the mother body is an important criterion for considering its performance, and it is also the main way to exert performance. If the combination is not tight, then failure will occur, affecting factors such as production.

Improve connector performance

For connector manufacturers, in addition to their productivity, they also care about the quality of their products. When it comes to product quality, many aspects are involved, such as the problem of high-speed micro-pitch interconnect performance of connectors. Do you know how to improve this performance of the product?

1. For connector products, in the early stages of design, multiple simulation cycles are performed to accurately quantify product performance before starting expensive processing.

2. When mating the connector, minimize stubs in the contact area. The longer the stub, the better the reliability, but the stub is an electrical load like an antenna.

3. Simplify contact points and improve signal path performance.

4.Short lead length to reduce signal loss

5. Add asymmetric footprints and contacts as much as possible, because the alternating design reduces the pair-wise crosstalk between pin rows and rows.

6. Optimize the connector branch area (BOR). Think of connectors as the key nodes in a link, not only about the nodes, but also about the links.

7. Where space permits, incorporate a common ground plane into the connector.

8. The choice of plastic molding will obviously affect the performance of the connector. These properties should be carefully considered: high temperature plastic suitable for RoHS, matching Dk to obtain the required impedance control, dimensional stability over temperature and time.

9. The shorter and straighter the signal path and connector contact, the better the signal integrity performance. But the balancing effect is that the connector must have sufficient normal force and withdrawal force, and it must also have a certain degree of robustness.

Common insulation materials

When using connectors, we have given the most consideration to safety, because if an accident occurs and the consequences are serious, a fire will occur. Therefore, in the manufacturing process, we need to consider the insulation material of the connector. There are three types of insulation materials that are more commonly used.

PBT material, generally used PBT material is added with 20% to 30% glass fiber, has the ability to resist cracking impact, anti-electricity, good abrasion resistance, low friction coefficient, good lubrication effect, oil and chemical resistance Good drug properties. It still has good dielectric strength under high temperature and high humidity. Its shrinkage ratio is between about and 60 ° C. Its temperature resistance is about degree. It has good moldability and flame resistance. Most of the plastic materials of current connector manufacturers choose PBT This plastic.

ABS material, it has good impact toughness, oil resistance, abrasion resistance, relatively easy to form, good rigidity, good rigidity, and its temperature resistance is about 100 degrees, generally used for auxiliary products in connectors.

LCP material, LCP material has a temperature resistance between 290 and 320, but its water absorption is large, and it is generally used for products with high temperature resistance and less pitch.

Reasons for the difference in connector plating quality

In order to ensure the quality of the gold-plated layer, connector manufacturers often repeatedly study the problems that may occur in the quality of gold-plating technology. Regarding the color of the gold-plated layer of the connector of the connector is different from the normal gold-plated color, and the gold-plated layer in the same product is significantly different The problems have been explained, and the basic mountains can be summarized into the following 4 reasons:

The effect of impurities in gold plating raw materials. When the gold plating process is performed, the impurities brought in by the plating solution's chemical materials will exceed the gold plating solution's use standard and will soon affect the color and brightness of the gold layer. The phenomenon of darkening and flowering of the cash layer or the interference of metal impurities will cause the effective range of the current density to be narrowed, which will show that the low end of the current density is not bright or the high end is not bright and the low end is not coated.

The current density of the gold plating is too large. When the total area of the plating parts of the gold plating process is incorrectly calculated, the value is larger than the actual surface area, and the amount of gold plating current is excessive. Or when the vibration electroplating gold is used, the amplitude is too small. In this way, the gold plating of some of the plated parts in the plating bath is rough, and the gold layer will be visually red.

The aging of the gold plating solution, during production, due to the use of some gold plating solutions for too long, excessive accumulation of impurities in the plating solution will inevitably cause the abnormal color of the gold layer of gold plating products.

The content of the alloy in the hard gold plating layer changes because of the needs of some gold plating processes. In order to improve the hardness and wear resistance of the connector, a hard gold plating process is generally used. Among them, gold-cobalt alloys and gold-nickel alloys are used more. When the content of cobalt and nickel in the plating solution changes, the color of the gold plating layer changes, so this will result in the same batch of products provided to customers. When the cash layer is not the same color.

When producing and designing connectors, because of different product requirements, there will also be different plating processes, especially when some customer-customized connector products often require relatively high electrical performance requirements, so connector manufacturers will Different gold plating processes are used according to different needs.
