Description

Technical Field

[0001] The utility model relates to the technical field of electrical connectors, in particular to an electrical connector with a locking component. Background Art

[0002] An electrical connector is a device often used in the power field. Existing electrical connectors include an electrical connector plug and an electrical connector socket. When using an electrical connector, through the cooperation between the electrical connector plug and the electrical connector socket, the electrical connection between the two is realized, and then the specific application effect of the electrical connector in the power field is achieved.

[0003] However, there are some problems with the current structure of electrical connectors: when the existing electrical connector plug needs to cooperate with the electrical connector socket, the operator needs to operate through tools to achieve it, resulting in a relatively cumbersome operation to complete the assembly and cooperation between the two, which is not convenient enough; in addition, the locking structure of the existing electrical connector products adopts an integral structure design, which increases the difficulty of mold manufacturing and also limits the product structure, making it impossible for some products to use their locking structures in a limited space. Summary of the Invention

[0004] By providing an electrical connector with a locking component in the embodiments of the present application, through the design of an elastic lock, especially the engagement between the first horizontal branch arm and the socket block, and the engagement between the second horizontal branch arm and the inner slot of the plug housing, double locking between the plug and the socket is achieved. This double locking mechanism greatly enhances the stability of the connection and reduces the risk of connection loosening or falling off caused by vibration or external force.

[0005] To achieve the above object, the utility model provides the following technical solutions: an electrical connector with a locking component, comprising

[0006] An electrical connector plug, comprising a plug housing;

[0007] An electrical connector socket, comprising a socket housing adapted to the plug housing, and a socket block is provided at the upper end of the socket housing;

[0008] An elastic lock, comprising an operation part and a first horizontal branch arm and a second horizontal branch arm disposed at the lower end of the operation part. An elastically deformable space is formed between the first horizontal branch arm and the second horizontal branch arm. The first horizontal branch arm is disposed on the upper surface of the socket housing and is engaged with the socket block, and the second horizontal branch arm is disposed in a slot provided inside the plug housing and is engaged with the slot, so that the plug housing is fixedly connected to the socket housing.

[0009] Compared with the prior art, the advantages of the utility model are as follows:

[0010] Through the design of the elastic latch, especially the engagement between the first horizontal arm and the socket latch block, and the engagement between the second horizontal arm and the inner slot of the plug housing, a double locking between the plug and the socket is achieved. This double locking mechanism greatly enhances the stability of the connection and reduces the risk of connection loosening or detachment caused by vibration or external force;

[0011] The design of the latch assembly takes into account the convenience of use. Through the operation part, the latch can be easily unlocked and locked without using additional tools, simplifying the installation and disassembly process and improving work efficiency;

[0012] The elastically deformable space of the elastic latch allows it to adapt to the slight size differences between the plug and the socket within a certain range, increasing the product's compatibility and adaptability. This design enables the connector to maintain a stable connection state under different environmental conditions;

[0013] The design of this latch assembly is compact and does not occupy extra installation space, contributing to the compact design of the device, which is particularly important in electronic devices or systems with limited space.

[0014] As an improvement, a socket groove for accommodating the socket latch block is provided on the outer side of the socket housing. A latch hook portion for engaging with the socket latch block is provided downward on one side of the first horizontal arm. The lower end of the first horizontal arm is embedded inside the socket groove so that the socket latch block is engaged with the latch hook portion. The engagement between the socket latch block and the latch hook portion ensures a firm connection between the socket housing and the first horizontal arm. This mechanical locking mechanism can effectively prevent the socket from loosening or falling off due to external force during use, improving the safety and stability of use. The design of the socket groove allows the socket latch block and the latch hook portion to be hidden inside or below the surface of the housing when connected, reducing the overall volume.

[0015] As an improvement, the elastic latch further includes a limiting portion. The limiting portion is horizontally arranged between the operation part and the first horizontal arm. A plug engaging portion protrudes from one side of the plug housing, and a plug hook portion for engaging with the limiting portion is provided downward on one side of the plug engaging portion. The plug hook portion is engaged with the limiting portion, further enhancing the stability of the connection between the elastic latch and the plug housing.

[0016] As an improvement, a first limiting block is provided on one side of the second horizontal arm, and a first limiting groove corresponding to the first limiting block is provided on one side of the slot. The first limiting groove is communicated with the slot. The distance between the side walls of the first limiting groove is greater than the distance between the slots so that one side of the first limiting block abuts against the bottom surface of the first limiting groove. Since the side wall distance of the first limiting groove is greater than that of the slot, when the first limiting block is inserted into the first limiting groove and abuts against the bottom surface, it can achieve more precise positioning. This tight contact not only reduces the possibility of shaking and displacement, but also provides a stable supporting force, making the whole structure more stable when stressed.

[0017] As an improvement, a second limiting block is provided at the lower end of the second horizontal arm, and the slot is provided with a second limiting groove which is concave corresponding to the second limiting block on the side wall of the lower end. The side wall of the second limiting block close to the first limiting block abuts against the side wall of the second limiting groove. On the premise that the first limiting block and the first limiting groove play a limiting role, the mutual cooperation of the second limiting block and the second limiting groove provides an additional limiting effect. This double limiting mechanism can more effectively prevent the second horizontal arm from shaking and displacing in the slot, thereby enhancing the stability of the whole structure.
