Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a connector that is resistant to mating and unmolding. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between the two. Examples include power plugs / sockets, IC sockets, telephone line plugs, etc.

[0003] Electronic connectors are widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent connection between electrical equipment or wires. Electronic connectors are generally divided into two categories: female connectors and male connectors. Female connectors and male connectors are used in sets, and by mating the female connector and male connector, the circuit is made conductive to achieve data transmission.

[0004] Current connectors typically consist of an insulating body and multiple conductive terminals. One end of each conductive terminal is fixed to the insulating body, while the other end is suspended in a slot on the insulating body. While this structure is relatively simple and can basically achieve the connector's conductive connection function, the conductive terminals are easily deformed and warped after repeated insertion and removal due to their suspended arrangement. The large lever arm of the conductive terminals results in a large bending moment at their root, making them prone to breakage. This affects the normal operation of the circuit, damages the connector, leads to poor product quality, a short lifespan, and lack of competitiveness, causing inconvenience to users and failing to meet current needs. Therefore, it is necessary to research a new technical solution to improve current connectors. Utility Model Content

[0005] In view of this, the present invention addresses the shortcomings of the existing technology, and its main purpose is to provide a connector that is resistant to repeated insertion and removal. This effectively solves the problems of existing connectors, such as the conductive terminals being easily deformed and warped after repeated insertion and removal, the conductive terminals having a large lever arm, resulting in a large bending moment at the root of the conductive terminal, which easily leads to breakage, affecting the normal operation of the circuit, damaging the connector, poor product quality, short product life, and lack of competitiveness.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mating-resistant connector includes an insulating body and conductive terminals. The insulating body includes multiple insertion slots and multiple positioning slots, each positioning slot being disposed at the front end of a corresponding insertion slot and communicating with the corresponding insertion slot. The conductive terminal includes an integrally formed mounting portion and multiple terminals. The mounting portion is fixedly disposed at the rear end of the insulating body. The multiple terminals are arranged side by side and extend forward from the front end of the mounting portion. Each terminal includes an integrally formed positioning spring and an elastic contact arm. The positioning spring extends forward from the front end of the mounting portion into the insertion slot, and the front end of the positioning spring is inserted into the positioning slot for positioning. The elastic contact arm extends forward from the rear end of the positioning spring and is disposed in the insertion slot.

[0008] As a preferred embodiment, the mounting part is provided with a snap hole, and the lower rear surface of the insulating body is provided with an undercut. The undercut is snapped and fixed with the snap hole. The structure is simple and stable, and the assembly is convenient and quick, which brings convenience to production.

[0009] As a preferred embodiment, the undercut is a semi-cylindrical boss undercut.

[0010] As a preferred embodiment, the positioning spring and the elastic contact arm form an F-shaped structure.

[0011] As a preferred embodiment, the front end of the elastic contact arm has a U-shaped structure, which increases the number of contact points and helps to enhance the reliability of the terminal contact connection.

[0012] As a preferred embodiment, the positioning spring is provided with a groove in the middle position, and the elastic contact arm is adapted to the shape of the groove, and the elastic contact arm extends forward from the rear end of the groove.

[0013] As a preferred embodiment, the front end of the mounting portion extends forward with a plurality of contact pins, which are used for conductive connection with circuitry on an external PCB board.

[0014] As a preferred embodiment, the lower surface of the insulating body is provided with multiple positioning buckles, which are used to cooperate with and fix external parts.

[0015] As a preferred embodiment, the lower surface of the insulating body is provided with a positioning post, which is used to cooperate with and fix external parts.

[0016] As a preferred embodiment, the lower surface of the insulating body is provided with positioning protrusions on the left and right sides, which are used to cooperate and fix with external parts.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0018] By setting multiple positioning grooves on the insulating body, each located at the front end of a corresponding insertion groove and communicating with it, the mounting part of the conductive terminal is fixedly set at the rear end of the insulating body. Each terminal includes an integrally formed positioning spring and an elastic contact arm. The positioning spring extends forward from the front end of the mounting part into the insertion groove, and the front end of the positioning spring is inserted into the positioning groove for positioning. The elastic contact arm extends forward from the rear end of the positioning spring and is set in the insertion groove. This connector structure, through the setting of positioning grooves, can effectively position the positioning spring, ensuring that the terminals are neatly arranged. After repeated insertion and removal, the terminals are not easily deformed or lifted. Through the cooperation of the elastic contact arm and the positioning spring, the lever arm of the terminal can be effectively shortened, reducing the bending moment borne by the terminal root, thus making it less prone to breakage. This makes the terminal more durable, less prone to breakage after repeated insertion and removal, ensuring the normal operation of the circuit, preventing damage to the connector, improving product quality, extending product life, making the product more competitive, bringing convenience to users, and meeting current needs.
