A kind of d-sub waterproof connector and its making method

Abstract

The invention discloses a D-SUB waterproof connector and a manufacturing method thereof. A semi-finished product of the connector comprises an insulation base, a terminal set, a front shell, a rear shell, a bolt, a sleeve and an insulating bracket, wherein a jack is formed in the insulation base; the terminal set is mounted in the jack; the tail end of the terminal set extends out of the rear shell; the jack is exposed on the front shell; the insulating bracket and the semi-finished product of the connector are subjected to integral injection molding; the insulating bracket and the semi-finished product of the connector are assembled in a sealing form to form a finished product of the connector. In the structure, the insulating bracket and the semi-finished product of the connector are integrally formed; the traditional gluing process is cancelled; the waterproof effect is better; the D-SUB waterproof connector does not depend on the special material and gluing and baking equipment and is not influenced by the factors of glue formula, environment, and the like; the process is simplified; the efficiency is increased; the quality is promoted; the integrally formed insulating bracket is in more stable size; no deckle edge is generated after the secondary low-pressure forming; the traditional gluing design has unstable size and easiness in generating deckle edge.

Description

[0001] Technical field: [0002] The invention relates to the technical field of connectors, in particular to a D-SUB waterproof connector and a manufacturing method thereof. [0003] Background technique: [0004] A connector is generally a point connector, a device that connects two active devices. Its function is very simple: to build a communication bridge between blocked or isolated circuits in the circuit, so that current can flow. Make the circuit realize the predetermined function. D-SUB waterproof connector belongs to a large type of rectangular connector. D-SUB (D-subminiature) is commonly known as VGA (Video Graphics Adapter) interface. This is an analog signal interface. There are different interfaces according to requirements. Each The interface is divided into male head (plug) and female head (socket). The traditional D-SUB waterproof connector has two pieces of iron shell and two pieces of plastic body. The terminals are processed by lathes. They are mainly des...

AI Technical Summary

Problems solved by technology

[0010] 1. The main body is formed separately, and is integrally connected with the front and rear iron shells through rivets. It needs to be installed integrally between the three, and the process is cumbersome;

[0011] 2. After the main body of the traditional D-SUB waterproof connector is installed, glue needs to be dispensed to achieve the waterproof effect. The quality of the glue is affected by the ambient temperature, high-temperature baking temperature, time, etc., which is difficult to control. The coating of metal parts will accelerate oxidation and cause damage; and the size is unstable after dispensing, and burrs are prone to occur during secondary low-pressure molding; the terminal group is assembled one by one, and the process is cumbersome;
