Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a stop terminal group and a connector. Background Art

[0002] A connector is a mechanical device used to connect or disconnect electrical or electronic devices. A connector usually consists of two parts: a plug and a socket. When the plug is inserted into the socket, a physical and electrical connection can be established to transmit signals or power on. However, the pins can easily fall off during the plugging and unplugging process, causing the circuit to break. A fixing method is required to prevent them from falling off. Existing similar technologies use stop springs on both sides of the conductive terminal.

[0003] However, it is found that when such a stop spring is subjected to a high external insertion and extraction force, the stop spring is easily deformed and damaged, causing the conductive terminal to fall off. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a stop terminal set and a connector, aiming to provide a stop terminal with a stop function and which is sturdy and durable, and a connector having the stop terminal set.

[0005] The solution adopted by the utility model to solve its technical problem is: a stop terminal group, including a number of connector terminals arranged in an array, a stop member for preventing the connector terminal from falling off upwards is vertically provided on the side of the connector terminal, the stop member includes an insertion portion and a positioning portion provided above the insertion portion for fixing the connector terminal so as not to fall off, the connector terminal is also provided with a positioning ring for preventing the connector terminal from falling off downwards, and the positioning ring is provided above the stop member.

[0006] By adopting the above technical solution, a stopper including an insertion portion and a positioning portion is vertically arranged on the side of the connector terminal. When the terminal is installed into the insulating base, the insertion portion is first aligned and inserted, and then the positioning portion is used to position the terminal to prevent it from falling off upwards. Then, the positioning ring on the stopper prevents the terminal from falling off downwards, and the terminal group is fixed to a suitable position.

[0007] Furthermore, four stop members are provided, and the four stop members are symmetrically arranged around the positions where the connector terminals need to be stopped.

[0008] By adopting the above technical solution, four stoppers are arranged in a ring shape around the terminal, cooperating with the positioning ring to achieve the stopping function to the greatest extent.

[0009] Furthermore, the insertion portion and the positioning portion are arranged in sequence from the head end to the tail end of the connector terminal, and the width from the insertion portion to the positioning portion of the stopper gradually increases.

[0010] Furthermore, the stopper and the positioning ring are an integrated structure with the connector terminal.

[0011] By adopting the above technical solution, the integrally formed stopper and positioning ring are prevented from being easily damaged and pulled off.

[0012] Furthermore, a connector includes a socket and a plug, wherein the plug includes an insulating base and a receiving through hole provided in the insulating socket, and the connector terminal is plugged into the receiving through hole.

[0013] By adopting the above technical solution, the plug and the socket are plugged together, and the plug terminal is inserted into the accommodating through hole of the socket.

[0014] Furthermore, a stop block is provided on the inner wall of the accommodating through hole, an insertion slot for inserting the stop member is provided on the stop block, and a stop groove for fixing the positioning part is provided between two adjacent insertion slots at the bottom of the stop block.

[0015] By adopting the above technical solution, a stop block is provided in the receiving through hole for cooperating with the stop terminal group for stopping. The top of the stop block abuts against the positioning ring, and the bottom abuts against the stop piece, so that the stop terminal is firmly installed in the receiving through hole to prevent the terminal from falling off. The stop block is provided with an insertion long hole for facilitating the insertion of the raised stop piece. When in use, the slender part of each stop piece is aligned with the insertion long hole for insertion. When it reaches the appropriate position, the positioning ring abuts against the stop block to prevent sinking for stopping. Then, by rotating each stop terminal, the sharp positioning part is aligned with the stop groove at the bottom of the stop block for fixing. This prevents the terminal from being pulled out together when plugging and unplugging, thereby achieving a stopping effect.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model realizes terminal stopping by installing four symmetrical stop members and positioning rings on the stop terminal in cooperation with the positioning blocks on the through holes in the insulating base, thereby preventing the terminals from detaching upward or downward, and the stop members and positioning rings are integrally formed with the connector terminals to ensure that they will not detach during the plugging and unplugging process, and the utility model is sturdy and durable.
