Chinese Utility Model No. 201204275 Specification

  If the slot dimension is larger than the housing bottom wall dimension, the housing bottom wall swings into the slot. If the size of the slot is smaller than the size of the bottom wall of the housing, the bottom wall of the housing cannot be inserted into the slot.

  Accordingly, an object of the present invention is to provide a USB connector in which a housing is firmly fixed to an insulating main body in view of the above-described problems of the prior art.

  In order to achieve the object, the electrical connector of the present invention includes a storage space into which the mating connector is inserted along the mating direction. The electrical connector includes an insulating main body, a plurality of conductive terminals inserted into the insulating main body, and a housing. The insulating body is formed with a slot extending along a direction orthogonal to the mating direction. Each conductive terminal has a contact portion stored in the storage space, and a solder connection portion extending from the insulating main body. The housing includes an extending wall that shields the insulating body and is inserted into a slot of the insulating body. The slot of the insulative main body is provided with a plurality of convex pieces that abut against the extending wall of the housing.

  Compared with the prior art, the present invention has the following advantages. The slot of the present invention is provided with a convex piece. An elastically deformable space is formed between the extending wall of the housing and the bottom surface of the slot. When the extended wall of the housing is inserted into the slot, the extended wall can be firmly fixed to the slot by elastic deformation of the extended wall.
