Description

Easy-lock connector with push-to-unlock structure

The present invention belongs to the technical field of connectors, especially an easy-lock connector with a push-to-unlock structure.

Conventionally, a wire-to-board connector provides multiple front/rear electrodes to connect a flexible printed circuit board (FPC) and a printed circuit board (PCB).

In order to enable the connector to be used in applications that require a narrower space, such as the automotive field or the application field of thin electronic products, people in the technical field described in this creation have thought about how to make thin connectors to In line with the aforementioned application fields; in addition to making thin connectors, we also consider whether automatic locking and manual unlocking functions can also be provided in the process of thinning connectors.

In view of this, the present invention proposes an easy-lock connector with a push-to-unlock structure, which can solve the problems that cannot be solved by the conventional technology.

The first objective of the present invention is to provide an easy-lock connector with a push-to-unlock structure, which can be used to connect a flexible printed circuit board, and can achieve the purpose of automatic locking and manual unlocking at the same time.

The second object of the present invention is to provide a single-piece structure of the rubber core and the shell according to the above-mentioned easy-lock connector with a push-to-unlock structure, and the fixing members or other structures provided by the rubber core and the shell can further improve the Snap and combine with each other to form a connector that can be connected to a flexible printed circuit board.

The third object of the present invention is to provide a first stopper body and a third stopper body to stop the deformation of the action portion according to the above-mentioned easy-lock connector with a push-to-unlock structure, so that the first stopper surface and the third stopper body are formed by the first stopper surface and the third stopper body. The stop surface determines the purpose of the deformation stroke of the acting part.

In order to achieve the above object and other objects, the present invention provides an easy-lock connector with a push-to-unlock structure that can be connected to a flexible printed circuit board with a plurality of notches and a plurality of wires. An easy-lock connector with a push-to-unlock structure includes a rubber core, a shell and a plurality of terminals. The rubber core includes a first body, a plurality of action parts and a plurality of terminal grooves. The plastic core forms an accommodating space for accommodating the flexible printed circuit board. The acting parts are respectively arranged on two sides of the first body. The terminal grooves communicate with the accommodating space and the outside of the rubber core. Wherein, each of the acting parts further includes a first stop body and a third stop body, and an opening is formed between the first stop body and the third stop body. The casing includes a second body and a plurality of pressing parts. The pressing parts are respectively arranged on two sides of the second body. The pressing portions are disposed corresponding to the first blocking body, the third blocking body and the opening. Wherein, each of the pressing portions provides a pressing surface, a cantilever, a locking block and an elastic member. The pressing surface connects the cantilever and the elastic member, and the free end of the cantilever forms a snap block to be able to correspond to one of the equivalent gaps. The terminals are arranged in the terminal slots so as to be able to connect the wires. Among them, the pressing surface is subjected to an external force Pressing causes the elastic pieces to deform, and then the latching blocks of the cantilevers move in the direction of unlocking the gaps, so that the flexible printed circuit board can be withdrawn from the accommodating space, and the elastic pieces are subject to the first stopper The stop of the body and the third stop body stops the continuous deformation, and the pressing surface is not pressed by external force, so that the snap blocks of the cantilevers lock the gaps, so as to prevent the flexible printed circuit board from exiting the accommodating space .

Compared with the traditional easy-lock connector with a push-to-unlock structure, the present invention proposes an easy-to-lock connector with a push-to-unlock structure, which belongs to a single-piece automatic snap-fit and push-to-unlock structure, and can be applied to a flexible printed circuit board , lock (or lock) and unlock the flexible printed circuit board.
