Detailed Description

An improved structure of a plastic part and a contact pin of a connector comprises a plastic part 1 in plug-in connection with a plastic shell of the connector, a cavity 1-1 for plug-in connection with the plastic shell is formed in the plastic part 1, a plurality of contact pins 2 are in plug-in connection with the outer portion of the plastic part 1, plug-in ends of the contact pins 2 extend into the cavity 1-1, the contact pins 2 form a T shape or an L shape, at least two positioning pieces 3 are plugged into the outer portion of the plastic part 1, and the contact pins 2 and the plastic part 1 and the positioning pieces 3 and the plastic part 1 are connected in an interference fit mode.

Contact pin 2 of connector in this application scheme can set up to T font or L font, and the structure of different shapes is suitable for different application environment installation and use. The installation and use are flexible, the T-shaped structure is suitable for vertical installation and use, and the L-shaped structure is suitable for horizontal installation and use.

And the contact pin 2 and the positioning plate 3 are both provided with bubble points which are connected with the plastic part 1 in an interference fit manner. Connect more stably, the phenomenon of droing appears when preventing to cooperate with the terminal, has improved the quality and the quality of product.

The inserting end of the positioning piece 3 is provided with a U-shaped opening positioning groove 3-1, so that the positioning is more accurate.

The lower part of the positioning sheet 3 is bent outwards to form a supporting part 3-2.

And the two sides of the outer part of the plastic part 1 are provided with clamping grooves 1-2 matched with the clamping hooks on the rubber shell of the connector. The rubber shell is convenient to be connected with the rubber shell in an inserting mode, and the rubber shell is firmer and not easy to loosen after connection.

A barb 1-3 is arranged in the cavity 1-1 of the plastic part 1. The rubber shell is convenient to be connected with the rubber shell in an inserting mode, and the rubber shell is firmer and not easy to loosen after connection.

The plastic part 1 is externally provided with a stop block 1-4 which extends outwards and is used for protecting a supporting part 3-2 of the positioning plate 3. The stoppers 1 to 4 function to protect the spacer 3.
