In an exemplary embodiment, as shown in fig. 1 to 10, the housing 1 is made of a metal plate such as a copper plate, a stainless steel plate, or the like by a machining process such as punching, cutting, bending, or the like, and a housing space extending in the executing direction is defined in the housing. The housing 1 has an insertion end 11 adapted to be inserted into a mating housing of a mating connector (200) in an insertion direction (longitudinal direction). The insulating body 2 is at least partially accommodated in the accommodating space of the housing 1. A plurality of conductive terminals 3 are mounted on the insulative body 2 to be electrically connected with mating terminals of the mating connector when the electrical connector 100 is inserted into the mating connector 200.

In an exemplary embodiment, as shown in fig. 1, 2, 4, 20-22, the insulator body 2 includes a tongue portion 21 and an annular flange portion 22. The first end (left end in fig. 4) of the conductive terminal 3 is held on at least one of the upper surface and the lower surface of the tongue-shaped portion 21. For example, the conductive terminals 3 include a row of first terminals 31 provided on the upper surface of the tongue-shaped portion 21 and a row of second terminals 32 provided on the lower surface of the tongue-shaped portion 21. An annular flange portion 22 projects around the tongue portion 21 for mounting the tongue portion 21 in the housing 1, and an annular protective frame 5 is provided on a front side surface of the flange portion 22, the protective frame 5 being adapted to cushion an impact of the mating tongue portion of the mating connector 200, thereby protecting the flange portion from an impact of the plug electrical connector during insertion and removal of the mating connector.
According to an exemplary embodiment, the housing 1 is integrally formed, and the flange portion 22 of the insulating body 2 and the housing 1 are in interference fit, so that the overall strength and the sealing performance of the electrical connector are improved.

The extension portion 52 extends from the main body portion 51 toward the tongue portion 21 on the front side surface of the flange portion 22. According to an exemplary embodiment of the present disclosure, the protective frame 5 may be attached to the case 1 by means of laser spot welding.
According to the electrical connector of the embodiment of the present disclosure, as shown in fig. 21 and 22, since the annular protection frame 5 is sleeved on the insulating body 2, the annular protection frame 5 has an extension portion 52 perpendicular to the insertion direction of the electrical connector and a main body portion 51 connected to the outer housing, the extension portion 52 receives a force in the insertion direction received by the mating connector during the insertion and extraction process and transmits the force to the housing 1 through the main body portion and further to the external component, thereby protecting the insulating body therein and reducing the insertion and extraction impact force received by the insulating body.
