Referring to FIGS. 2 and 3 , the shielding shell 3 is made of metal material, and has a sleeve portion 31 surrounding the tongue plate 12 and a pair of clamping pieces 32 inserted in the two clamping grooves 13 . The socket portion 31 includes a bottom plate 311, side plates 312 bent upward from both ends of the bottom plate 311, and a top plate 313 formed by bending and joining the two side plates 312 oppositely. Extend horizontally backward to the butt seam 33 at the tail end of the shielding shell 3 . A through hole 321 is respectively formed in the middle of the two clamping pieces 32 , and a part of the clamping piece located behind the two through holes 321 is punched inward and correspondingly buckled into the gap 103 behind the clamping groove 13 . The rear edges of the top plate 313 and the bottom plate 311 are respectively bent upwards and downwards along the front end surface 100 of the base 11 to form the connecting portion 34 connecting the socket portion 31 and the two clamping pieces 32, and the clamping pieces 32 are self-connecting One end of part 34 is bent. As shown in FIG. 4 , a pair of positioning grooves 35 are provided in the connecting portion connected to the top plate 313 for the fixing member 5 to pass through, and the two positioning grooves 35 are arranged laterally on both sides of the butt joint 33 and are left-right symmetrical.

Referring to Figures 4 and 5, the two fixing parts 5 have the same structure and are correspondingly arranged in the above two positioning grooves 35, and the two fixing parts 5 are elongated. Each fixing member 5 includes an insertion portion 51 inserted in the positioning groove 35 and a second connecting section 52 formed by bending 90 degrees from the end of the first connecting section 51 away from the butt seam 33. The first and second The free ends of the connecting sections 51 , 52 are respectively provided with first and second short end portions 511 , 521 . Wherein the first end 511 is formed by bending toward the direction of the second connecting section 52 and is parallel to the second connecting section 52 , and the second end 521 is formed by bending toward the direction of the first connecting section 51 and is parallel to the second connecting section 52 . A connecting segment 51 is parallel. The first and second ends 511 and 521 are correspondingly fixed in the first holding hole 15 (see FIG. 2 ) and the second holding hole 17 (see FIG. 2 ).

As shown in FIG. 3 , the positioning body 4 has a plurality of through slots 41 for positioning the tails of the conductive terminals 2 . The clamping piece 32 at the bottom of the shielding housing 3 extends backward out of a support bar 322 , and the support bar 322 is located at the bottom of the positioning body 4 to prevent the positioning body 4 from loosening downward.

When assembling, first assemble the conductive terminal 2 on the insulating body 1, then assemble the positioning body 4 on the rear end surface of the insulating body 1, secondly set the shielding shell 3 on the periphery of the insulating body 1 from front to back, and finally install the fixing member 5 . Before the fixing part 5 is inserted into the positioning groove 35, the operator needs to rotate the fixing part 5 to the vertically upward position of the second connecting section 52, because the length of the first end part 511 is wider than the width of the positioning groove 35, and at the same time In order to ensure that the first connecting section 51 can be smoothly inserted into the positioning groove 35 , it must be ensured that the vertical height of the positioning groove 35 is not less than the length of the first end portion 511 . After the first connecting section 51 is inserted into the bottom of the positioning groove 35 , it is rotated backward by 90 degrees so that the first end portion 511 is inserted and fixed in the first holding groove 15 . During the rotation, the operator needs to open the second connecting section 52 outward at a certain angle to prevent the second end 521 from interfering with the side wall of the base 11 and affecting the smooth positioning of the first end 511 in the first holding hole 51 Inside. When the first end portion 511 is rotated to a horizontal state, the operator simultaneously buckles the second end portion 521 into the second fastening hole 17 , so that the second connecting section 52 is clamped on the side wall. Since the fixing member 5 is made of a material with good strength and toughness, breaking the second connecting section 52 outward during installation will not cause it to undergo plastic deformation and fail.

Part of the structure of the clamping piece 32 of the electrical connector of the present invention is arranged in the gap 103 of the base 11, so that when the electrical connector is docked with the docking connector, the shielding shell 3 is prevented from coming out of the insulating body 1, and the fixing member 5 The setting further enhances the holding force between the shielding shell and the insulating body, ensuring that the electrical connector can still be firmly connected to the shielding shell and the insulating body under the action of a large insertion force. In addition, due to the good toughness of the fixing part, the electrical connector can offset part of the external force during the plugging and unplugging process, so that there will be no looseness between the shielding shell and the insulating body, so that it has better performance to meet the needs of customers.
