The pushing device 24 includes a sliding member 241 slidably mounted on the casing 21 and an elastic member 242 respectively connecting the casing 21 and the sliding member 241. The sliding block 241 is convexly provided with a projection that can be inserted into the casing 21. The bump 243 in the channel 214 of the bracket, a contact portion 244 capable of contacting the electronic card 3, and a second receiving chamber 245 at a position opposite to the contact portion 244. The length of the projection 243 is shorter than the length of the channel 214 of the housing 21 described above. The elastic member 242 is a spring, and both ends of the elastic member 242 extend into the first receiving chamber 215 of the casing 21 and the second receiving chamber 245 of the sliding member 241, respectively. The positioning device 25 includes a positioning block 251 provided on the second arm portion 222 of the slide cover 22, and a positioning member 252 capable of sliding along the periphery of the positioning block 251. A recessed area 253 is formed on the periphery of the positioning block 251, and two first and second curved surfaces 254 and 255 respectively extend from the recessed area 253 in opposite directions and form different curvatures. Each of the curved surfaces 254 and 255 forms an arc shape, and is defined with a recessed area 253 to form a substantially heart shape. As for the positioning member 252, it can be a torsion spring, which is pivoted on the housing 21 and defines an axial direction, and the connecting portion 256,-can be offset in the lateral direction of the axial direction and can be the same as the offset when offset. The product-free end 257 of the restoring force in the axial direction and a cantilever 258 opposite to the free end 257. In addition, a positioning position is defined at the lowest position of the depression in the depression area. The M277200 electrical connector 2 includes a shielding case 26 that is shielded from the outside of the casing 21 and is electrically connected to the circuit board 4. The shielding casing 26 is made of a metal material and is placed in the casing 21 to prevent electromagnetic interference. Inside the electronic card 3. The shielding case 26 has a central wall 261. A plurality of L-shaped pins 262 are arranged on opposite sides of the central wall 261, and one side of the wall 263 is provided between two adjacent pins 262. This uses the housing 21 to be placed on the circuit board, the conductive terminals 23 and the wires on the circuit board 4 to be welded to form an electrical path, the shield housing 26 is placed outside the housing 21, and each connection on the shield housing 26 is shielded. The feet 262 are soldered on the circuit board 4, so that the casing 21 and the shield casing 26 which have been combined with the pushing device 24, the positioning device 25 as described above can be positioned on the circuit board 4. As shown in FIG. 3, one end of the electronic card 3 is inserted into the accommodating space 226 of the slide cover 22, and the other end of the electronic card 3 extends into the receiving area 213 of the housing 21. As shown in FIGS. 4 and 5, when the sliding cover 22 is pushed for the first time, the first arm portion 221 and the second arm portion 222 of the sliding cover 22 advance along the two side walls 211 and 21Γ of the casing 21 to push the sliding member. The abutting portion 244 of 241, so the sliding member 241 drives the positioning member 252 to move toward the front end of the channel 214 in the insertion direction of the electronic card 3. When the slider 22 starts to travel, the free end 257 of the positioning member 252 first meets and follows The second curved surface 255 travels. Due to the setting direction of the second curved surface 255, the free end 257 of the positioning member 252 is guided to travel obliquely, and the positioning member 252 accumulates a torque. When the free end 257 of the positioning member 252 reaches the convex turning point at the junction of the second curved surface 2 5 5 and the recessed area 2 5 3, the accumulated torque of the positioning member 2 5 2 will force the free end 257 to pass the convex turning point along the recessed area 253. Travel until the slider 241 has reached the front end of the channel 214, and when the external force M277200 disappears, it will elastically move in the opposite direction (the restoring force along the electronic card 3 and P2 will cause the slider to advance in the direction of 252 u). However, due to the positioning member 2 (: please stop moving at the positioning position of the recessed area 253 and stop moving), the electronic card 3 is positioned in the electrical connector 2 at this time. When the sliding cover 22 is pushed toward the direction = 'the sliding member 241 forces the electronic card 3 in the insertion direction position ^ 14 and the other end travels' the free end 257 of the positioning member 252 is disengaged =' the torsion continues along the recessed area 253 toward the first Curved area 所示: shown at 2: 6 ^ When the free end 257 of the positioning member 252 comes to the recessed area 253 and the first surface 254 six μααπ Shitubitu 4 the convex turning point of the boundary, the torsion will force the fixation "and 257 Beyond the convex turning point, when the external force disappears: The returning force of the card \ 242 causes the sliding material 241 to move in the reverse direction (Z daughter card 3 exits in the direction of travel), and the free end 257 of the positioning member is twisted == the first surface At 254, at this time, the sliding member M pushes the sliding cover 22 'by resisting the force to cause the sliding cover 22 to be ejected and electrically connected to complete the card ejection action, and the positioning member is disengaged from the third wall μ i. 71 resets towards the axial direction again (as shown in the second form of Figure 7. From this, you can see that the new type of electronic card electrical connector 2 can indeed make the electronic card 3 quickly connect to the electrical connection H or lightly withdraw the card.: Because the end of the month / month 22 can be designed to be completely inserted in the electronic device after being pushed into position Shell surface-body shape, so it is not known that the electrical connection is a structure with protruding parts for users to take out, so it can make the appearance of the mouth of the electronic product more consistent and enhance the overall electronic products.
