Talking about the four major structures and manufacturing processes of waterproof connectors for vehicles

What is a waterproof connector? As the name suggests, this product is waterproof. So do you know the structure and process of the waterproof connector for cars? The following small series will introduce you to the structure and process of the waterproof connector for cars in detail. It will provide you with three aspects: overview, structure and process. Elaborate.



I. Overview

Automotive waterproof connector is a connection component that professional technicians often contact. Its function is mainly to connect the blocked or isolated circuit in the circuit, so that the current can be completely and smoothly formed in the circuit Realize the predetermined function. The specifications and structure of the waterproof connector are various. Generally, it is composed of four basic general structural parts, which are contact parts, shells, insulating parts and other accessories.




2. Structure

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

1. The contact parts are the core components used to complete the electrical connection function. Generally, the positive and negative contact parts are used to form the contact butt, and the electrical connection is completed through the insertion and insertion of two contact parts with different parameters. The positive sign represents rigidity. The specific shape can be divided into cylinders, square pillars, and flats. The material used for manufacturing is brass or bronze. Negative means that the socket is a more critical part. It needs to form a tight connection with the rigid contact part according to the deformation that occurs when the elastic structure and the rigid are inserted.

2. The shell of the waterproof connector is the outer cover part. It is equipped with an insulating installation module and a mechanical protection device inside, which can make the plug and the socket successfully complete the accurate docking so that the connector is fixed to the equipment used.

3. The insulating part is the bottom base or the mounting plate. Its function is to arrange the contact parts in accordance with the specified position and spacing, and to ensure that the insulation performance between the contact parts and the housing is kept good at all times, because of good insulation Resistance and voltage resistance are basic technical requirements when using insulating materials.

4. Other accessories represent many small and small parts inside the structure of the waterproof connector, such as screws, nuts, sealing rings, positioning pins, connecting rings, spring rings and other standard universal parts.




3. Process

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

2. To a certain extent, the advantages and competitiveness of products depend on the level of process technology, and need to constantly improve and improve production and processing technology, which can allow the connector to essentially improve its manufacturing efficiency and quality assurance capabilities. From the fine and rigorous manufacturing process, we will optimize the methods such as narrowing the gap and thinning the thickness to ensure that the products reach the advanced level in ultra-fine.

3. The waterproof connector adopts low-temperature and low-pressure molding technology to use the sealing and physical and chemical principles of hot-melt materials to achieve good insulation and high temperature resistance, and to ensure that the welding point is not pulled by external force on the wire after sealing the device At the same time, the contact point of the connector body and the wire has anti-shock characteristics, effectively ensuring the reliability, stability and long service life of the product.
