One end of the insertion portion 121 extends a soldering piece 122 perpendicular to the insertion portion 121, and the other end extends a chevron-shaped contact piece 123. The insertion portion 121 of the socket terminal 12 is correspondingly inserted into the socket terminal slot 116; the soldering piece 122 is exposed on the outer surface of the socket body 11 and soldered to a printed circuit board; the contact piece 123 is inserted into the socket terminal slot 116 and The socket-welding portion 13 has a holding portion 131 bent at one end and a bent portion 132 at one end, and the other end is bent and extended. There is a fastening portion 133, and a fastening groove 134 is defined in the middle of the fastening portion. The upper side groove wall of the fastening groove 134 is formed with a u-moving slope 135. The socket soldering piece 13 is inserted into the corresponding=the second assisting slot 117, and the latching portion 131 is held in the holding slot UK; the connecting piece 4 is connected to the corresponding external printed circuit board; the fastening part 133 ^ end In the extension 114, the lower end is inserted into the receiving slot 1171. Referring to the second and third figures, the plug connector 20 includes a plug M345369 body 21, a plurality of plug terminals 22 and two plug soldering tabs 23. The plug body 21 is made of a plastic material and has a substantially rectangular parallelepiped shape and has a bottom wall 211. The plug body 21 is provided with two rows of plug terminals 212 arranged at equal intervals. A receiving groove 213 is defined at each end of the front surface of the plug body 21 and at both ends of the rear surface. A square recess 214 is defined in the middle of the bottom wall 211. A second soldering groove 215 is defined at each end of the plug body 21, and the second soldering grooves 215 are respectively located outside the two ends of the groove 214 and communicate with the receiving groove 213. Referring to FIG. 2, FIG. 3 and FIG. 6 , the plug terminal 22 has a strip-shaped contact portion 221 , and two ends of the contact portion 221 respectively extend from a strip-shaped soldering leg 222 perpendicular to the contact portion 221 . And the holding leg 223, the soldering leg 222 and the holding leg 223 are located on the same side of the contact portion 221. The contact portion 221 is inserted into the plug terminal slot 212 and extends into the recess 214. The soldering leg 222 is received in the plug terminal slot 212, and the other end extends outside the plug body 21 and is soldered to the corresponding external printed circuit. The holding leg 223 is inserted into the plug terminal slot 212. Referring to the third and fifth figures, the plug soldering piece 23 has a rectangular parallelepiped retaining portion 231, and a substantially semi-elliptical card extends perpendicularly outwardly from the front surface and the lower portion of the rear surface, respectively. The buckle portion 232 and the two latching portions 232 are symmetrically disposed with respect to the retaining portion 231. The end of the latching portion 232 is formed with an arc-shaped contact surface 233 and an upper surface of the contact surface 233 and the contact surface 233. The associated card holds a 9 M345369 bevel 234 and a mating ramp 235 that is positioned below the contact surface 233 and that is connected to the lower edge of the contact surface. The upper portion of the contact surface 233 and the latching ramp 234 form a second automatic latching ramp 236, and the lower jaw of the contact surface 233 and the mating ramp 235 form a mating ramp 237. The retaining portion 231 of the 3-slot splicing die 23 is fastened to the corresponding second soldering pad and the upper end of the holding portion 231 is soldered to the corresponding printed circuit board, so that the plug car P brush circuit latching portion 232 and the (4) The circuit (4) is set together. The end is received in the second soldering groove 215, and the other end is inserted into the receiving groove 213. Another delay Please refer to Figures 1 and 2. The plug connector 10 is sized to correspond to the size of the two latch portions 232 of the distance A 23 between the socket and the socket scale 13 to the socket material 13. Please refer to the first and second plugs of the connector 1 and the seventh diagram. The present board-to-board socket connector 10 is assembled on the socket connector 10, and the boss portion 115 in the recess m is correspondingly received. The plug connector 2〇123 is connected to the contact piece of the socket terminal 12 of the plug connector 1G, so that the contact portion 221 of the plug terminal 20 of the plug/20 is abutted to the plug connection 20 is connected to the plug 10 and the plug connector 20 Electrically conductive. The latching portion 232 of the plug soldering tab 23 is engaged in the latching slot U4 of the socket outlet soldering tab 13. When the connector 20 is pulled out from the socket connector 10, the latching portion 232 of the M345369 plug soldering tab 23 slides along the first automatic latching ramp 135. Out. When the plug connector 20 is inserted into the receptacle connector 1 ,, if the latching portion 232 is not slid into the first automatic latching ramp 135, the elastic force of the latching portion 133 acts on the butting guide 237, thereby The plug soldering tab 23 is ejected from the fastening portion 133, thereby facilitating timely detection that the latching portion 232 is not inserted into position. Referring to the sixth figure, the contact portion 221 of the plug terminal 22 extends into the recess 214. Therefore, when the receptacle connector 1 is plugged into the plug connector 2, the contact piece 123 of the receptacle terminal 12 is not affected by the plug body. The effect of the inner wall of the recess 214 of 21 is blocked, thereby facilitating the electrical connection of the receptacle terminal 12 to the plug terminal 22. Referring to the second and seventh figures, the retaining wall II?3 is disposed between the receiving slot 1171 and the retaining slot η72, and the retaining wall 1173 is received in the socket soldering tab 13 The holding portion ΐ3ι is enclosed in the space enclosed by the fastening portion 133, so that when the socket soldering piece 13 is soldered to the circuit board, the plastic around the holding wall 1173 and the holding wall 1173 is heated to a certain extent. At this time, the limited 'space enclosed by the catching portion 131 and the fastening portion 133 can suppress the progressive expansion thereof, thereby reducing the amount of deformation of the plug body 21 caused by the welding of the welded piece 13. As mentioned above, the board-to-board connector of this creation is connected by a plug on the one hand! The snap portion of the plug soldering piece 23 of 20 is engaged with the snap groove 134 of the socket soldering piece 13 of the socket connector 1 to effectively 11 M345369 to avoid the socket connector when mechanical impact or other external force is applied. Disengagement from the plug connector 20 results in a secure coupling of the plug connector 20 to the receptacle connector 10. On the other hand, when the plug connector 20 is mated to the receptacle connector 10, the latching portion 232 presses the latching portion 133 to engage the latching portion 232 before the latching portion 232 is engaged with the latching slot 134 of the socket soldering tab 13. When the elastic portion of the portion 133 is deformed, a large force needs to be applied; when the second automatic card 10 holding the inclined surface 236 of the latching portion 232 starts to contact with the first automatic latching inclined surface 135 of the fastening groove 134, no need to force only the buckle The elastic force of the connecting portion 133 and the inclined surface of the two automatic latching ramps can cause the latching portion 232 to automatically snap into the latching slot 134, thereby completing the mating of the plug connector 23 with the receptacle connector 13. Therefore, it is easy to judge whether or not the socket connector 10 and the plug connector 20 are butted together.
