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, a plug 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 existing connector is unreasonable, the connection of the plug sheet and the female terminal is unreliable, and therefore the connector is easy to break instantly, and the connector has the defects of unreliable performance, unreliable connection and inconvenient assembly.

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 high reliable connector.

For realizing the above-mentioned mesh, the utility model discloses a highly reliable connector, including the masterbatch shell, set up the terminal piece in the masterbatch shell, the masterbatch shell in be provided with the mounting groove that is used for placing the terminal piece, one of masterbatch shell serve and be provided with the contact pin hole that is linked together with the mounting groove, the one end of terminal piece have with external conductor looks crimping portion of connecting, the other end of terminal piece bend to the crimping portion direction by the contact pin hole and be the U type and be formed with the centre gripping shell fragment, and be formed with between the inner wall of centre gripping shell fragment and mounting groove and supply contact pin male grafting chamber, the contact pin can pass the contact pin hole and alternate in the grafting chamber, and constitute the joint cooperation of contact pin and terminal piece.

The beneficial effect of above-mentioned structure is: the clamping spring plate of the terminal piece is designed into a U shape, the contact pin is inserted into the terminal piece, the clamping spring plate can play a role in guiding the contact pin, the insertion force of the contact pin can be reduced, the clamping spring plate can clamp the contact pin in the insertion cavity, the pulling force of the contact pin is increased, and therefore the contact pin can be connected with the terminal piece more compactly, and the connector has the advantages of being simple in structure, stable and reliable in performance, reliable in connection and convenient to assemble.

Particularly, the terminal piece on be provided with spacing piece, the mounting groove of female rubber shell in correspond spacing piece department and be provided with spacing hole, and correspond one side department in spacing hole on the inner wall of mounting groove and be provided with and insert the direction inclined plane, spacing piece can slide to spacing downthehole along inserting the direction face, and constitute the spacing cooperation of terminal piece and female rubber shell. The guide inclined plane can play a guide role in the limiting piece and can reduce the insertion force of the terminal piece, so that the terminal piece and the master rubber shell are convenient to assemble, the pulling force of the terminal piece can be increased through the limiting hole, and the connection of the terminal piece and the master rubber shell can be more compact.

Particularly, the outer wall of the mother rubber shell is provided with a clamping plate, one end of the clamping plate is provided with a hook-shaped part, and the other end of the clamping plate is provided with a pressing part. The female rubber shell is provided with a clamping plate which can be connected with the male rubber shell in a buckling manner, so that the assembly of the female rubber shell and the male rubber shell is facilitated.
