Description

Plug-in type connector

Technical Field

The utility model relates to a connector technical field, concretely relates to plug-in type connector.

Background

A connector is a device that connects two active devices and is used to transmit current or signals. The main matching fields of the electric connector comprise traffic, communication, network, IT, medical treatment, household appliances and the like, and the development of the connector technology is strongly dragged due to the rapid development of the product technical level and the rapid growth of the market in the matching fields. To date, connectors have been developed into products with various categories, various specifications, various structural styles, fine professional directions, obvious industrial characteristics, and standardized standard systems. The existing connector comprises a male rubber shell, an insertion sheet arranged in the male rubber shell, a female rubber shell matched with the male rubber shell, and a female terminal arranged in the female rubber shell. The structural design of the public gluey shell of current connector is unreasonable, leads to this public gluey shell to take place to warp easily, and the contact pin is unreliable with being connected of female terminal to the condition of instantaneous interruption takes place easily for this connector, and this connector still has the performance unreliable, connect unreliable, assemble inconvenient defect.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, connect reliable, assemble convenient plug-in connector.

In order to achieve the above purpose, the utility model adopts a plug-in type connector, which comprises a male rubber shell, a contact pin arranged in the male rubber shell, a female rubber shell connected with the male rubber shell, and a female terminal arranged in the female rubber shell, one end of the contact pin is provided with an inserting part exposed outside the male rubber shell, a plurality of grooves are respectively arranged on the bottom wall of the male rubber shell at intervals corresponding to one side of the inserting part, one end of the female terminal is provided with a crimping part connected with an external lead, the other end of the female terminal is provided with a plugging frame connected with the plugging part, one end of the insertion frame is provided with a contact elastic sheet, one end of the contact elastic sheet bends and extends towards the inside of the insertion frame and forms an arc-shaped convex contact part, and an inserting space is formed between the arc-shaped convex contact part and the inner wall of the inserting frame, and the inserting part is inserted into the inserting space and forms the clamping fit of the inserting pin and the female terminal.

The beneficial effect of above-mentioned structure is: be provided with the recess on the diapire of public gluey shell to this public diapire of gluing the shell is thinner, and diapire thickness is even, and the shrink phenomenon of diapire is not obvious, thereby this public gluey shell is difficult for taking place to warp. And be provided with the contact shell fragment on the female terminal, the contact shell fragment can compress tightly the contact pin in the grafting frame of female terminal to the contact pin is compacter with being connected of female terminal, thereby this connector has simple structure, stable performance reliable, connect reliable, the convenient advantage of assembly.

Particularly, a fool-proof limiting column is arranged on the bottom wall of the male rubber shell and corresponds to one side of the insertion part. The fool-proof limiting column can play a fool-proof role, and can effectively prevent the contact pin from being reversely inserted into the circuit board.

Particularly, the outer wall of the plug-in frame of the female terminal is provided with a limiting sheet, a clamping groove is formed in the female rubber shell corresponding to the limiting sheet, and the limiting sheet is clamped in the clamping groove and forms limiting matching of the female rubber shell and the female terminal. The limiting piece can play a role in preventing loosening, can prevent the female terminal from loosening and falling, can ensure that the female terminal is more compactly connected with the female rubber shell, and is favorable for improving the working reliability of the connector.
