Description

Structure of electrical connector

The present invention is to provide a structure of an electrical connector, especially a structure of an electrical connector that is more convenient to manufacture and can reduce the probability of glue overflow.

Press, the so-called electrical connectors are mainly used for the connection points of signals and circuits between electrical products or internal electrical products, which are mainly divided into male and female connectors that can be docked with each other, thereby transmitting electronic signals or power .

A general electrical connector will have a plastic or metal shell, and the shell is provided with circuit boards or terminals that can be docked with each other, and a plastic shell carrying the circuit board or terminals, so as to achieve the docking effect, and some The electrical connector will first install the circuit board in the housing, and then directly inject curable gel into the housing, thereby directly fixing the circuit board and the wires connecting the circuit board through the cured gel, instead of the conventional plastic shell, to achieve reinforcement Fixed effect and waterproof function.

However, when the above electrical connector is used, the following problems and defects still need to be improved:

First, when injecting the cured colloid, it is necessary to provide a breathable perforation in the casing, which is troublesome in manufacturing.

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

Therefore, how to solve the problems and deficiencies of the above-mentioned practice is the one where the applicants of this new type and the relevant manufacturers engaged in this industry are desperate to study the direction of improvement.

Therefore, in view of the above-mentioned deficiencies, the applicant of this new type has collected relevant information, evaluated and considered through multiple parties, and based on years of experience accumulated in this industry, through continuous trial and modification, it has been designed that this manufacturing is more convenient and A new patent for the structure of electrical connectors that reduces the chance of spilling glue.

The main purpose of the present invention is to match the effect of the gas outlet part through the injection part, so that the manufacturing can be more convenient and fast, and cooperate with the plug to prevent the situation of overflowing glue.

To achieve the above objective, the main structure of the present invention includes: a housing, a front mating port defined at one end of the housing, a rear end surface defined at one end of the housing facing away from the front mating port, and a device 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 waterproof curing member provided in the housing and located between the installation baffle and the installation rear end surface, an injection portion defined on the installation rear end surface, and a side defined on the installation rear end surface and located on the side of the different injection portion The outlet department.

With the above-mentioned structure, the user can first set the sealing member on the circuit board, and then connect the connecting wire to the circuit board, then the circuit board can be inserted into the housing at the rear end surface of the installation and installed in the installation In the perforation, the plug will completely close the position of the perforation, and then the liquid waterproof solidification part can be injected into the injection part, and the air in the housing is discharged from the air outlet part, thereby allowing the waterproof solidification part It can be filled between the installation baffle and the rear end of the installation. When the liquid waterproof curing component is completely injected and fills the space between the installation baffle and the installation rear surface, you can stop the injection of the waterproof curing component and wait for the waterproofing of the housing The curing piece is cured, thereby strengthening the connection effect between the circuit board and the connecting line through the curing effect of the waterproof curing piece, and can achieve the waterproof function, and because the installation baffle and the installation rear end surface only have installation through holes, there will be overflow The possibility of glue, but the installation perforation in this case will be closed by the blocking member, so there will be no chance of overflowing glue, which can greatly increase the quality effect during production.

With the above technology, it is possible to break through the problems that conventional electrical connectors are troublesome and poor in quality during manufacture, and achieve the practical progress of the above advantages.
