Three ways to secure connector pins?

One. Connector pin press-in: The pin is fixed by forced press-in.

1.The pins are easy to install and the insulated conductors do not need to be stripped, ensuring a good electrical connection without damaging the conductors.

2.There is no need for cable return, saving the investment in cables.

3.There is no need to cut off the main cable, and it can be used as a tap point at any position of the cable.

4.Low cost and minimal installation space requirements.

5.The joints are completely insulated, and cable branches can be made without stripping off the insulating skin of the cable.

Two. Connector pin epoxy: insulator.

and after the shell is punched, epoxy resin is used.

Fixed pins. 1.Strong chemical resistance, resistance to acids, alkalis and organic solvents.

2.The molding shrinkage is low, the dimensional stability is good, and the cracking probability is low.

3.Mechanical properties.

and excellent heat resistance.

4.It has high adhesive strength, especially suitable for products with inserts and molded case packaging of coils and electronic devices.

5.It has excellent electrical properties and can be used as an insulating material for high frequency and high voltage.

Arc resistance and surface leakage resistance are stronger than general insulating materials.

Three. Connector pin point riveting: After pressing, the point riveting shell fixes the pins.

1.The structure is simple, the reliability is high, and it is a cost-effective method of permanent fixed assembly.

2.The assembled metal components are strong, tight and stable, with high impact and corrosion resistance, shock resistance and weather resistance.

Strong. 3.The processing process has no vibration, no pollution, no noise, environmental protection, energy saving, fast, efficient, high quality and beautiful appearance.

4.It can be fixed by multi-point riveting without adding any adhesive.

The knowledge can be focused on Jing Cheng karma.

What is the structure of the pin jack and connector?

At present, the structure of pin jack connector products is mainly soldered and elastic clamping

1. The pin and shell of the connector are welded with the inner conductor and the outer conductor of the cable respectively, the advantage of this structure is that it saves materials, and the disadvantage is that the assembly and welding are more troublesome, and its three-medium intermodulation performance largely depends on the consistency of the inner and outer conductors of the cable and the connector welding, and when the cable is bent or because of temperature changes, it is easy to cause changes in the assembly size of the inner conductor, which affects the system performance of the connector.

2. The elastic clamping type means that the inner conductor of the connector and the cable, the outer conductor of the shell and the cable are connected by elastic clamping, the advantage of this structure is that the processing and assembly are more convenient, and the stability of the mating size is also more stable, and the disadvantage is that the cost is higher and the consumables are large.

1. Threaded connection method, which is often used in connector pins and jacks with large size contacts and working in strong vibration environments. After the connection is completed, it can be installed with a fuse or nut to prevent loosening, which is reliable to use, but the continuous and unloading speed is slow.

2. The bayonet connection method is a reliable and fast form of connection and separation. Most of the electrical connectors in the form of the Card 121 connection have a visual display of the correct connection and locking, which can be seen from the small hole on the side of the electrical connector connection nut.

3. The plug-in connection method is a multi-purpose connection form. The common plugging connection has two kinds of structures, ball or pin, because there is no mechanical labor-saving mechanism, once the plug is mistaken, the mechanical resistance increases significantly, and can be found in time.

4. The cabinet connection method is used for the electrical connector on some equipment that needs to be blindly connected close to the frame, which can make the electrical equipment lighter and smaller, easier to maintain and more reliable. Connector pins and jacks are typically constructed with a floating or elastic contact design to ensure their proper connection.

There is a high-current shrapnel microneedle module that is a one-piece shrapnel design, which only needs to touch the DUT with one end and conduct signal transmission at the other end, which has a strong connection function. When the current is transmitted, it circulates in the same material, which is stable and reliable, and after gold plating and hardening, the shrapnel has better conductivity and a longer service life.

The environmental resistance of the electrical connector is improved by the insulator and the interface sealing body. In order to adapt to the high temperature, low temperature and flame retardant of the product, it ensures the stability and reliability of the geometric dimensions of the parts. Most insulators are molded with thermoset plastics.

The interface sealing body and wire sealing body are molded with silicone rubber. Contacts include male and female contacts, sometimes referred to as pin jacks.

The connection methods are divided into: soldering, crimping, pressing, and winding, etc., to realize the circuit connection.

Connector wholesale can find TXGA, bulk purchase connector is best to find connector manufacturers, excellent quality, and relatively cheap, like some conventional connectors, manufacturers are generally faster.

The information found is that the pins are divided into straight and curved pins, and TE's amplifier connector series rectangular terminal pins.

The structure of connector pins is flat bottom type, plug board type, bending type, double-ended type, soldering type, threaded type and other shapes!

1. There are two solder joints to be connected together (GND).

2. GND (ground) on the circuit diagram and circuit board represents ground wire or 0 wire. GND means public end, which can also be said to be land, but this land is not a land in the true sense. It is a hypothetical ground for the purpose of application, and for the power supply, it is the negative pole of a power supply.

It is different from the earth. Sometimes it needs to be connected to the earth, sometimes it doesn't, depending on the situation.

3. Welding: also known as welding and grafting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics in a heated, high-temperature or high-pressure manner.

What are the precautions for the pin connector?

First, the working environment with too high temperature will accelerate the corrosion of the needle core of the pin, forming surface oxidation, resulting in the loss of contact pressure.

Second, the humid and humid environment will also accelerate the corrosion of the pin, resulting in the dampness of the needle core on the surface, and the plastic film will be slowly affected by its corrosion.

Third, the wear life between the needle cores will be reduced after a long period of use.

Fourth, the pores of the pin will corrode in harsh environments, the edges will be deformed, and some metal particles on the surface will also be corroded.
