[ detailed description ] of the utility model

Embodiment one:

referring to fig. 1-5, the present embodiment is a USB TYPE connector 100, which includes a plastic terminal body 1, a rear plug 2 assembled at the tail of the plastic terminal body 1, and a housing 3 integrally covering the plastic terminal body 1 and the rear plug 2.

The plastic terminal body 1 is a one-time molding structure, and comprises a plastic body 11 and a metal terminal 12 buried in the plastic body 11. The metal terminal 12 comprises a horizontal section and a vertical section, the plastic body 11 comprises a sealing section 111 and a tongue piece section 112, the horizontal section of the metal terminal 12 is distributed in the tongue piece section 112, and the vertical section is distributed in the sealing section 111.

The sealing section 111 of the plastic body 11 is formed with a mounting groove 113, and the rear plug 2 is assembled in the mounting groove 113 to form a complete plastic body, and the rear side surface and the lower surface of the rear plug 2 respectively form the rear side surface and the lower surface of the plastic body.

A plurality of through grooves 21 penetrating through the upper surface and the lower surface are arranged in the rear plug 2, and the vertical section of the metal terminal 12 penetrates through the through grooves 21 and extends downwards to protrude out of the lower surface of the rear plug 2, so that a plug-in terminal structure is formed. In order to improve the assembly firmness of the rear plug 2 and the plastic terminal body 1, the structure of the rear plug 2 and the plastic terminal body 11 is optimally designed in this embodiment. Specifically, the left and right side surfaces of the rear plug 2 are provided with vertical first limiting protruding strips 22, the plastic main body 11 is correspondingly provided with first limiting clamping grooves 114 matched with the first limiting protruding strips 22, and the first limiting clamping grooves 114 are provided with insertion openings (not labeled in the figure) with downward openings. During assembly, the first limit protruding strips 22 are inserted into the first limit clamping grooves 114 from the insertion opening, so that the degree of freedom of assembly of the rear plug 2 and the plastic main body 11 in the front-rear direction can be limited, and the two can be tightly connected in the front-rear direction. In addition, the two sides of the top of the rear plug 2 extend upwards to be provided with a buckling part 23, the plastic main body 11 is correspondingly provided with a buckling slot 115 for the buckling part 23 to be inserted and buckled, and the buckling slot 115 is provided with a buckling limiting step 116 for the buckling part 23 to buckle for realizing backstop. During assembly, the buckling part 23 is inserted into the buckling slot 115 and buckles the buckling limiting step 116, so that the degree of freedom of assembly of the rear plug 2 and the plastic main body 11 in the Z direction is realized, and the tight connection of the rear plug 2 and the plastic main body 11 in the Z direction is realized. In addition, by the left and right inner walls of the mounting groove 113 defining the left and right side surfaces of the rear plug 2, tight connection of both in the left and right directions is achieved.
