The insulating body includes a base and a tongue formed by protruding from the base to one side. A receiving groove is provided on both sides of the base. One side of the opening protrudes into the opening with an extension part, and the extension part protrudes into the receiving groove to form a positioning part. Several terminal slots are provided on the base and the tongue. Several conductive terminals are fixed in the terminal slot of the insulating body. The casing is covered on the insulating body, and the casing has two side walls. The two side walls respectively extend backward to form a holding part, and the two ends of the holding part respectively extend to one side to form an elastic clip arm. The arm surrounds a chute and a holding groove connected with the chute. The elastic clip arms on both sides of the housing are inserted into the receiving groove of the base, so that the positioning part slides into the holding groove along the chute, and the elastic clip arms are clamped on both sides of the positioning part.

As mentioned above, the electrical connector of the present invention is not only easy to assemble, but also is held in the holding groove by the positioning part, and the two elastic clip arms are respectively held on one side of the positioning part, so that the housing can be firmly fixed on the insulating body. Therefore, the housing can be prevented from detaching from the insulating body during assembly or use.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the utility model in detail, the following will be described in detail in combination with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the electrical connector 100 of the present invention includes an insulating body 10 , a plurality of conductive terminals 20 and a housing 30 .

Please refer to FIG. 2 and FIG. 3 , the insulating housing 10 includes a base 11 and a tongue 12 protruding forward from the middle of the base 11 . The base 11 and the tongue 12 are provided with a plurality of terminal slots 13, the two sides of the base 11 are respectively provided with a receiving groove 111, and the two sides of the base 11 are respectively provided with a socket extending to the front surface of the base 11 and communicating with the receiving groove 111. The opening 14 has an extension portion 141 protruding from an edge of the opening 14 into the opening 14 . The extension portion 141 protrudes into the receiving groove 111 to form a columnar positioning portion 142 connected to the inner sidewall of the receiving groove 111 . A middle portion of the upper surface of the base 11 is provided with an ax-shaped buckle 15 .

Please refer to FIG. 2 again, the plurality of conductive terminals 20 are retained in the insulating housing 10 by integral in-molding. The plurality of conductive terminals 20 respectively have a fixing portion 21 , a contact portion 22 extending obliquely forward from one end of the fixing portion 21 , and a welding portion 23 extending backward from the other end of the fixing portion 21 .
