electrical connector

technical field

The utility model relates to an electrical connector, in particular to an electrical connector with reduced assembly procedures.

Background technique

According to the fact that electrical connectors are often seen in electrical products, their main purpose is to conduct power or signals. Therefore, electrical connectors have been widely used in the connection of information products and are indispensable components.

In fact, the use of electrical connectors is not limited to the aforementioned electrical products, but is also widely used in the circuit systems of automobiles and locomotives as the connection of lines. In order to ensure that the contact terminals inside the electrical connector can be stably positioned and locked.

As shown in Figures 1 to 3, it is a three-dimensional exploded view, an assembled perspective view and an assembled cross-sectional view of a known electrical connector. The electrical connector is composed of a body 10 and a terminal position assurance (TPA) 20 and a fixed ring seat 30 are formed. Wherein, the body 10 is a step-shaped tubular body. As shown in FIG. 3 , the interior of the body 10 is radially integrally formed with a spacer 101 with a plurality of pin holes 102, so that a spacer 101 is formed on both sides of the spacer 101. The positioning portion 103 and a joint portion 104 . And the top surface of the joint portion 101 defines a connected buckle groove 105 , and a retaining tenon 106 protrudes from the rear end of the buckle groove 105 .

The terminal positioning member 20 defines a plurality of terminal grooves 201 aligned with the pin holes 102 in the axial direction, and an elastic positioning claw 202 extends behind the opening of each terminal groove 201 for snapping and positioning of the claw groove 601 of the plug-in terminal 60 . When assembling, after dispensing glue on the periphery of the terminal positioning part 20, insert it through the opening of the positioning part 103 of the main body 10, and after waiting for a period of time, the terminal positioning part 20 is glued into the positioning part 103; then, another The waterproof rubber pad 40 is sleeved on the opening of the positioning portion 103 , so that the plurality of outlet holes 401 axially opened by the waterproof rubber pad 40 are opposite to the terminal slots 201 . The plug-in terminal 60 is inserted through the outlet hole 401 of the waterproof rubber pad 40, and is fixed in the terminal groove 201 for positioning, so that the plug pin 602 at one end passes through the pin hole 102 of the middle partition 101, and extends into the joint 104. The wire 603 at the other end of the plug terminal 60 protrudes from the outlet hole 401 .

The fixed ring seat 30 is a ring whose size and shape correspond to the inside of the joint part 104. The fixed ring seat 30 is inserted into the opening of the joint part 104 of the main body 10, and the elastic buckle 301 protruding from the top surface of the fixed ring seat 30 is formed. Buckle in the buckle groove 105, and use the tenon 106 as the stopper for the elastic buckle hook 301 to come out, so that the fixed ring seat 30 is buckled in the joint part 104, so as to provide a complementary electrical connector (known equipment, not given) As shown in the figure) is inserted into the fixing ring seat 30, so that a plurality of contact terminals of the complementary electrical connector can be inserted into the plug pin 602 to form an electrical connection.

Wherein, in order to provide a waterproof effect between the complementary electrical connector and the main body 10 , a waterproof rubber ring 50 is sheathed between the intermediate piece 101 and the fixing ring seat 30 .

The significant defect of the aforementioned electrical connector is that the terminal positioning member 20 must be glued to the tubular positioning portion 103 of the main body 10. In addition to having to wait for drying time, it also consumes a lot of manpower and manpower, so that the production capacity cannot be increased. In particular, when the electrical connector of the present invention is pulled out and separated from the complementary electrical connector, the plug-in terminals 60 will pull the terminal positioning member 20 out of the opening of the positioning part 103 due to the reaction force, thereby causing the electrical connector to break. damaged and in need of improvement.
