Description

Technical Field

[0001] The utility model relates to a terminal connector, in particular to a terminal connector with a claw sleeve structure. Background Art

[0002] Terminal connectors are an accessory that electronic engineers often come into contact with. Its function is to build a bridge of communication between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve its intended function. Connectors are widely used in various line connections.

[0003] Existing connectors generally include a male socket and a female plug. Both the male socket and the female plug can be used as fixed ends on the device. The male socket and the female plug are generally connected by interference fit. Since the cable is easily bumped by the outside, the female plug may become loose or detached from the male socket, thereby affecting the normal operation of the equipment.

[0004] In the prior art, the connection between male and female terminals is mostly a plug-in connection, and the male and female terminals need to have an interference fit to enable the current to flow stably and ensure the stable operation of the equipment. However, the interference fit of the traditional plug-in connection is too tight, making it difficult to plug and unplug. If the interference fit between the male and female terminals is loose, it is easy to cause an unstable connection.

[0005] Therefore, it is necessary to improve the traditional terminal connector. Utility Model Content

[0006] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a terminal connector with a claw sleeve structure.

[0011] An insulated female end bracket, wherein the female end bracket and the male end bracket are provided with a fixed structure at both ends, and the rod body thereof has second sockets having the same number as the first sockets;

[0012] A plurality of female terminals are one-to-one inserted into and fixed to the plurality of second jacks, one end of each female terminal protrudes from the back surface of the female terminal bracket, a receiving cavity is provided inside the female terminal bracket, and a plurality of side clamping holes are distributed on the side edge of the protruding end of the female terminal;

[0013] There are multiple claw-shaped terminals, each female terminal is equipped with a claw-shaped terminal, the claw-shaped terminals are accommodated in the accommodating cavity and the claw end of the claw-shaped terminal is the first entry end, and the straight male terminal can be inserted into the claw-shaped terminal and spread the claw end after entering the female terminal so that the bent section of the claw end is stuck in the side clamping hole.

After the straight male terminal 6 enters the first socket from the back surface of the male terminal bracket 5 and extends out from the docking surface of the male terminal bracket 5, the curved sleeve 7 is clamped in the side groove 55.

[0033] The outer end of the curved sleeve 7 is provided with a welding hole 71 for welding, and the wall surface of the welding hole 71 is provided with at least one circle of grooves 72. Before installing the terminal connector of the utility model, the curved sleeve 7 is welded to the cable, and the stripped end wire core of the cable is fed into the welding hole 71, and solder is injected to fill the welding hole 71 with solder, and the solder fills the grooves 72 at the same time. After the solder solidifies, the wire core is fixed to the curved sleeve 7, which increases the bonding force between the curved sleeve 7 and the cable.

[0034] The female terminal assembly includes an insulating female terminal support 1, a plurality of female terminals 2 and a claw terminal 3.

[0035] The female end bracket 1 is a strip-shaped structure, and the two ends of the female end bracket 1 and the male end bracket 5 are fixed structures, and the rod body has the same number of second sockets 14 as the first sockets. Figure 1 As shown, there are four second jacks 14. The fixing structures at both ends of the female bracket 1 and the male bracket 5 are as follows: the first end 11 of the male bracket 5 is provided with a first clamping hole, a first clamping cap 12 is fixed at the first clamping hole, the second end 16 of the male bracket 5 is provided with a second clamping hole 15, one end of the female bracket 1 is provided with a cylindrical sleeve 54 for the clamping cap 12 to enter and form an interference fit, and the other end of the female bracket 1 is provided with a second clamping cap 51 that can enter the second clamping hole 15 and form an interference fit.

[0036] Multiple female terminals 2 are one-to-one inserted into and fixed to multiple second jacks 14 , and one end of each female terminal 2 extends out of the back surface of the female terminal bracket 1 , which has a receiving cavity inside and multiple side clamping holes 21 distributed on the side edge of the extended end of the female terminal 2 .

The claw-shaped terminal 3 is accommodated in the accommodating cavity and the claw end of the claw-shaped terminal 3 is the first entry end. After the straight male terminal 6 enters the female terminal 2, it can be inserted into the claw-shaped terminal 3 and spread the claw end so that the bent section of the claw end is stuck in the side clamping hole 21.

[0038] When the four straight male terminals 6 of the utility model are inserted into the corresponding four female terminals 2, and the straight male terminals 6 enter the claw-shaped terminals 3, the claw ends of the claw-shaped terminals 3 are stretched open, and the bent sections thereof are stretched open and stuck in the side clamping holes 21. It can be seen that the female terminals 2 and the claw-shaped terminals 3 are in stable contact. When the straight male terminals 6 are pulled out, the claw ends of the claw-shaped terminals 3 reset themselves.
