Description

The structure of the electrical connector and its manufacturing process

The present invention provides a structure and manufacturing process of an electrical connector, in particular to a structure and manufacturing process of an electrical connector that is more convenient to manufacture and can reduce the probability of glue overflow.

According to, the so-called electrical connector is mainly used to connect the signal and circuit between electrical products or within the electrical product. It is mainly divided into male and female connectors that can be connected to each other to transmit electronic signals or power. .

General electrical connectors will have a plastic or metal shell, and a circuit board or terminal that can be connected to each other and a plastic shell carrying the circuit board or terminal are arranged in the shell to achieve the effect of docking, and some The electrical connector will first install the circuit board in the shell, and then directly inject the curable glue into the shell, so as to directly fix the circuit board and the wires connected to the circuit board through the cured glue, instead of the conventional plastic shell, to achieve reinforcement Fixed effect and waterproof function.

However, when the above-mentioned electrical connector is used, there are the following problems and deficiencies that need to be improved:

First, when injecting the cured gel, a perforated hole must be provided on the shell, which is troublesome in manufacturing.

Secondly, when the cured glue is injected, it is easy to cause glue overflow at the gap of the shell, which will affect the manufacturing quality of the electrical connector.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the present invention and the related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the inventor of the present invention has collected relevant information, evaluated and considered by multiple parties, and has accumulated many years of experience in this industry, through continuous trials and modifications, to design this kind of manufacturing that is more convenient and more convenient. The patent of the invention of the structure and manufacturing process of the electrical connector that reduces the chance of glue overflow.

The main purpose of the present invention is to make the manufacture more convenient and quicker through the effect of the injection part and the air outlet part, and to cooperate with the plugging part to prevent the overflow of glue.

To achieve the above objective, the main structure of the present invention includes: a housing, a mating front port defined at one end of the housing, a mounting rear surface defined at an end of the housing facing away from the mating front port, and a device A mounting baffle in the housing, at least one mounting hole formed on the mounting baffle, at least one circuit board provided on the mounting hole, a plurality of plugs provided on the circuit board, and a plurality of connections connected to the circuit board Line, a water-proof curing member arranged in the housing and located between the installation baffle and the installation rear end surface, an injection part defined on the installation rear end surface, and one defined on the installation rear end surface and located on the side of the different injection part The vent of the office.

With the above-mentioned structure, the user can first install the plugging member on the circuit board, and then connect the connecting wire to the circuit board, and then the circuit board can be inserted into the housing at the rear end of the installation, and pass through the installation. Inside the perforation, at this time, the stopper will completely close the position where the perforation is installed, and then the liquid waterproof curing part can be injected into the injection part, and the air in the shell can be discharged from the outlet part, thereby allowing the waterproof curing part It can be filled between the installation baffle and the installation rear surface. When the liquid waterproof curing part is completely injected and filled in the space between the installation baffle and the installation rear surface, the injection of the waterproof curing part can be stopped and the housing will be waterproofed. The curing part is cured, thereby strengthening the connection effect between the circuit board and the connecting line through the curing effect of the waterproof curing part, and can achieve the waterproof function, and because the installation baffle and the installation rear face only have the installation perforation, there will be overflow. The possibility of glue, but the installation perforation in this case will be sealed by the plug, so there will be no chance of glue overflow, which can greatly increase the quality effect during production.

With the above-mentioned technology, a breakthrough can be made to solve the problem that the conventional electrical connector is troublesome and poor in quality during manufacture, so as to achieve the practical advancement of the above-mentioned advantages.
