Description
Technical Field
The utility model relates to a connector technical field, concretely relates to high reliable 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, 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.
In order to realize the above purpose, the utility model discloses a highly reliable connector, including female gluey shell, set up terminal piece in female gluey shell, with female gluey shell matched with needle file, set up the contact pin that just is connected with the terminal piece on the needle file, the one end of terminal piece have the crimping portion that is connected with the external conductor, the other one end of terminal piece have the interface of pegging graft mutually with the contact pin, the bilateral symmetry of this interface is provided with two holding pieces, and is provided with circular arc transition portion between two holding pieces and the interface, and the below department that corresponds two holding pieces on the interface is provided with the arc bellying portion, arc bellying portion and two holding pieces between be formed with the grafting space, the one end of contact pin alternate in the grafting space and constitute the joint cooperation of contact pin and terminal piece.
The beneficial effect of above-mentioned structure is: the terminal piece adopts the design of bikini centre gripping structure, is favorable to increasing the clamping-force of terminal piece to the contact pin to can improve the connection reliability of contact pin and terminal piece, and the circular arc transition portion on the holding piece can play the guide effect to the contact pin, is favorable to reducing the insertion force of contact pin, thereby should connect and have simple structure, stable performance is reliable, connect reliable, assemble convenient advantage.
Particularly, the terminal piece on one side department that corresponds crimping portion is provided with the spacer, the masterbatch shell on correspond spacer department and be provided with the locating hole, the inner wall of masterbatch shell on one side department that corresponds the locating hole be provided with the direction inclined plane, the spacer can slide to the locating hole along the direction inclined plane in, and constitute the spacing cooperation of terminal piece and masterbatch shell. The guide inclined plane can play a guide role in the positioning sheet and can reduce the insertion force of the terminal sheet, so that the terminal sheet and the master rubber shell are convenient to assemble, the positioning hole can play a role in preventing loosening, the pulling-out force of the terminal sheet can be increased, the terminal sheet can be prevented from being pulled out of the master rubber shell, and the working reliability of the connector is improved.
