Further, referring to FIG. 2 and FIG. 3 , the slider 300 includes a base plate 320 and first limiting plates 340 vertically arranged on opposite sides of the base plate 320; Two second limiting plates 220 are protruded on the opposite side of the hook, and the two second limiting plates 220 are distributed on both sides of the U-shaped elastic piece 200; A slide rail (not shown) for sliding the base plate 320 is formed on the U-shaped elastic piece 200 .

In order to allow the base plate 320 of the slider 300 to slide into the U-shaped elastic piece 200 more smoothly, the second limiting plate 220 is set on the U-shaped elastic piece 200, and the first limiting plate 340 is also set on the base plate 320, so Set so that the second limiting plate 220 forms a slide rail for the substrate 320 to slide on the U-shaped elastic piece 200; the substrate 320 uses the first limiting plate 340 to abut against the second limiting plate 220, and smoothly along the sliding rail Sliding into the U-shaped elastic piece 200 , the second limiting plate 220 on the U-shaped elastic piece 200 forms a displacement limit for the first limiting plate 340 on the base plate 320 .

Further, referring to Fig. 2 and Fig. 3, the second locking member 310 is a positioning column 310 provided on the first limiting plate 340; There is a snap button 230, and the snap button 230 extends toward the end where the substrate is inserted; the second limiting plate 220 is provided with an anti-retraction slot 221, and the positioning column 310 is snapped to the anti-retraction The card ejection slot 221 , the protrusion 330 is engaged with the elastic button 230 .

Specifically, after the U-shaped shrapnel 200 and the socket 100 are mated, and the first locking assembly 210 is locked for the first time, the slider 300 can be pushed to move forward, and the positioning column 310 can be snapped into the second limiting plate 220 The anti-retraction slot 221 on the top is used to lock the slider 300 inserted into the U-shaped elastic piece 200 . In addition, in order to further enhance the connection strength between the U-shaped elastic piece 200 and the socket 100, a protrusion 330 is provided on the base plate 320 of the slider 300. The compression deformation of the U-shaped elastic piece 200 is limited, so that the U-shaped elastic piece 200 remains straight in the cavity 101 of the socket 100 , so that the connection between the U-shaped elastic piece 200 and the socket 100 is more stable. In order to facilitate the disassembly of the slider 300 from the U-shaped elastic sheet 200, the elastic sheet button 230 is formed by extending the U-shaped elastic sheet 200 on the top surface toward the direction of the substrate 310. During the disassembly process, a downward vertical pressure can be applied on the elastic sheet button 230. The directional force causes the U-shaped elastic piece 200 to shrink and deform in the cavity 101 of the socket 100, and then the U-shaped elastic piece 200 is pulled out from the socket 100 to complete the unlocking action.

Further, referring to FIG. 2 and FIG. 3 , the U-shaped elastic piece 200 is further provided with a third limiting plate 240 protruding from the side opposite to the hook, and the third limiting plate 240 is close to the base plate 320 One end of the insertion is set, and the third limiting plate 240 is distributed on both sides of the U-shaped elastic piece 200 where the second limiting plate 220 is set, and the third limiting plate 240 is connected to the second limiting plate 220.

In order to prevent the protrusion 351 of the clamping plate 350 from hindering the entry of the substrate 320 into the cavity 101, an extension groove 102 is provided to advance the clamping plate 350 on the substrate 320. The center can be exposed outside the extension groove 102 , thereby ensuring that the U-shaped elastic piece 200 can enter the cavity 101 of the socket 100 smoothly.

Further, in order to speed up the locking speed of the slider 300 in the curved elastic piece 200, the second limiting plate 220 is also provided with a pre-engagement groove 222 that fits and engages with the positioning post 310. The card slot 222 is spaced apart from the anti-back card slot 221 , and the pre-card slot 222 is set away from the end of the base plate 320 inserted into the U-shaped elastic piece 200 . In this way, before the slider 300 slides into the U-shaped elastic piece 200 , the positioning column 310 can be pre-engaged in the pre-engagement groove 22 , and thus the base plate 320 can temporarily stay in the slide rail of the U-shaped elastic piece 200 . When the slider 300 slides into the U-shaped elastic piece 200 , the positioning column 310 can shorten the distance on the slide rail and slide into the U-shaped elastic piece 200 faster.

Further, referring to FIG. 2 and FIG. 3 , the slider 300 further includes a booster block 360 disposed on the end of the base plate 320 away from the clamping plate 350 . With such arrangement, it is convenient for the user to grab the booster block 360 and push the base plate 320 into the U-shaped elastic piece 200 easily.
