New description: [New technical field] The present invention relates to an electrical connector, and more particularly to a GPS electrical connector. [Prior Art] According to the GPS electrical connector, the socket generally includes a socket fixed to the main body of the GPS device and a plug that interfaces with the socket. The plug includes a plug body, and two plug-in portions are protruded from the plug body, and a clamping piece is fixed in the plug-in portion, and a card slot is formed on the latching piece. The socket comprises a socket body of a plastic material, and two sockets are defined in the socket body, and a fastening component is fixed in the socket, and a hook body is arranged on the buckle component. However, when the plug of the electrical connector is connected to the socket, the broadcast portion of the plug extends into the socket of the socket, and the clamping piece presses and slides over the hook body of the buckle member, so that the card slot and the hook body Align and snap each other; when the plug is pulled out of the socket, the hook body is released from the card slot of the holding piece, and the clamping piece is pressed and slides over the hook body to slide out of the slot. When the electrical connector is pressed and pulled over the hook body during the plugging and unplugging process, the hook body will press against the socket body, so that the socket body is easily damaged after multiple insertions and removals; and the plug body of the electrical connection H is When exposed to the external environment, the socket body is exposed to the main body of the GPS device, so that when the plug and the socket are electrically connected to each other, the electronic components in the main body of the GPS device are electrically interfered with each other. The external electromagnetic environment is also easy for the internal electronics. The component is disturbing. M339118 [New Content] The purpose of this creation is to provide an electrical connector with stable electrical connection, good anti-electromagnetic interference performance and long life for the above-mentioned deficiencies. To achieve the above object, the electrical connector of the present invention includes a socket and a plug. The socket includes a socket body and a metal casing covering the socket body. The socket body is provided with two butt holes, and at least one side of the docking hole communicates with the outside, and the metal casing has a card holder corresponding to the side of the connecting hole and the outside. groove. The plug includes a plug body, a snap member and a metal housing. = Two pairs of joints on the body, the plug body is opened - a retaining hole that extends to the docking =. The fastening component is held in the holding hole of the ^ Λ ^ ^ guard hole, and the bottom end is convexly provided with an inverted hook portion, and the metal shell is spliced to the plug body. The butt joint W is docked in the butt hole of the socket, and the hook portion at the end of the snap member is buckled with the retaining groove on the metal shell inserted into the socket. As described above, the creative electrical connection is robbed and touched. The cutting plug adds a shielding metal body, the socket is increased and the metal casing is shielded, so the electromagnetic interference resistance is improved; the electric t ^ ^ is taken End hook

The positioning plate 5 is arranged such that the spacing between the connecting portions 22 of the plug terminal % is such that the contact portion 24 abuts against the blocking wall 163 of the plug body 1 , and the abutting portion 25 passes through The receiving groove 161 of the plug body 1G protrudes from the front surface u of the plug body 1 to abut the socket 6. Please refer to the second figure. tt Holding part 31, the holding part = Fig. 'The fastening piece 3' has the end of the long plate, the end of the end is bent vertically to form a fold and a bent portion 32, and the card holding portion 3 is folded! The upper end of the convex portion 33 is convexly provided with a _ hook portion A in the (8) and is formed by the hook body 1 body 311. The holding portion 31 is fastened to the fixing hole 32 to abut against the plug body 1 () temple in the fixing hole 181 On the wall of the hole, the folded portion f of the folded portion 34 protrudes from the pair: 'The elastic arm 33 extends in the retaining hole 18, and the upper surface of the 17 is fastened to the socket 6. M339118 The second and third figures of the eye The metal housing 4 includes a first housing 4i and a first housing 42. The first housing 41 has a first cover plate 41 having a substantially rectangular plate shape, and the first cover plate 41 is closed to the plug body 1 On the lower surface of the cymbal, a first side plate 4 垂直 is vertically bent on both sides of the first cover 410. The front end of the first cover 410 is bent upward to form two positioning strips 412, and the positioning strip 412 is disposed. In the positioning slot 110, the end of the two positioning strips 412 is connected with a cover plate 413 which is closed on the recess 13 of the plug body 10. The first cover 41, the first side plate 411 and the cover plate 413 are provided with a plug. The first side plate 411 is inwardly punched with a spring piece 4m, and the elastic piece 4111 is snapped into the buckle groove 152. The front end of the first side plate 411 is bent inward. The card arm 4112 is extended forwardly, and the end of the card arm 4112 is bent outward to have an elastic portion 4113. The card arm 4112 is placed in the slot 171 of the abutting portion π, and the elastic portion 4113 is elastically abutted against the metal of the socket 6 after the docking. The outer casing 63 is such that the plug 1 is opposite to the socket 增加 to increase the holding force, so that the electrical connection between the plug 1 and the socket 6 is more stable. The first side plate 411 protrudes outwardly from the block 4114. The second cover plate 420 has a substantially rectangular plate shape, and the second cover plate 420 is closed on the upper surface 13 of the plug body 1 . The two sides of the second cover plate 420 are vertically bent and extend out of the second side plate 421 . The second side plate 421 is punched inwardly with a card 4210 that is engaged with the groove 151 of the side surface 15 of the plug body 10. The second side plate 421 is provided with a card that engages with the card block 4114 of the first housing 41. The groove 4211.
