Car waterproof connector structure and process

I. Overview

The waterproof connector for the vehicle is a connection component that is frequently contacted by professional technicians, and its function is mainly to shield the circuit from being blocked or isolated in the circuit, so that the current can be completely and smoothly formed in the circuit. Implement the predetermined function. The waterproof connector is available in a variety of sizes and configurations. It is generally made up of four basic structural components, which are contact parts, housings, insulation parts and other accessories.

Second, the structure

The four basic structural components of the vehicle waterproof connector are described in detail as follows:

1. The contact component is a component that is used to complete the function of the energization connection. Generally, the contact parts of the positive and negative contact parts are used to form a contact butt joint, and the electrical connection is completed by the contact piece insertion action of two different parameter uses respectively. The positive is representative of the rigidity, and its specific shape can be divided into a cylinder, a square column, and a flat shape. The material selected for the production is made of brass or bronze. Negative is a relatively critical part representing the jack. It is based on the deformation of the elastic structure and the rigid insertion to create a tight connection with the rigid contact parts.

2. The housing of the waterproof connector is the outer cover part. It is internally provided with an insulation mounting module and a mechanical protection device, which enables the plug and the socket to be smoothly and accurately connected so that the connector is fixed to the use device.

3. The insulating part is also the bottom base or the mounting plate. Its function is to arrange the contact parts according to the specified position and spacing, and to ensure that the insulation properties between the contact parts and between the outer casings are kept good at all times because of good insulation. Resistance and withstand voltage performance are the basic technical requirements for the use of insulating materials.

4. Other accessories represent many small and small parts inside the waterproof connector structure, such as screws, nuts, seals, locating pins, connecting rings and spring rings.

Third, the process

1. The waterproof connector has precise technical performance, and it is precisely processed from design, process and quality control. The first is the use of high-precision processing equipment for its special processing of molds, the selection of experienced production personnel and advanced equipment technology to achieve high-quality product manufacturing.

2, the product's advantages and competitiveness to a certain extent depends on the level of technology, the need to constantly improve and improve the production and processing technology, which allows the connector to improve its manufacturing efficiency and quality assurance capabilities. From the fine and rigorous manufacturing process, we will optimize the products in terms of pitch reduction and thin thickness to ensure that the products reach the advanced level in super fine.

3, waterproof connector uses low temperature and low pressure molding technology to utilize the sealing and physical chemistry of hot melt raw materials, to achieve good insulation and high temperature resistance, and to ensure that the solder joints are not pulled by external force after the sealing device At the same time, the contact points of the connector body and the wire have impact resistance characteristics, which effectively ensure the reliability, stability and long service life of the product.

There are hundreds of types of waterproof connectors used in general cars. There are hundreds of connectors required for a single model. As people demand safety, environmental protection, intelligence, and economy. The higher the rate, the increasing use of automotive electronic devices, and the number and scope of actual applications will gradually increase.
