[0023] The invention provides an electrical connector.

[0024] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The electrical connector includes a male socket 10 and a female socket 20, the female socket 20 is provided with a socket 100, the male socket 10 is provided with a plug 200 adapted to the socket 100 and a slider 300 provided on the plug 200; the socket 100 is provided with a cavity 101 for the plug 200 to be plugged in, the plug 200 is provided with a first locking piece 210 adapted to be locked with the socket 100, the slider 300 is provided with a second locking piece 310 and a protrusion 320 adapted to be locked with the plug 200, the slider 300 is held in the plug 200 by the protrusion 320, the slider 300 is clamped on the plug 200, and the plug 200 is tightly plugged with the socket 100.

[0025] Specifically, by providing a plug 200 on the male socket 10 of the electrical connector and providing a socket 100 on the female socket 20, the plug 200 is plugged into the cavity 101 on the socket 100, so as to achieve plug-in connection between the male socket 10 and the female socket 20 of the electrical connector. In order to lock the male socket 10 and the female socket 20, a first locking member 210 is provided on the plug 200, and the first locking member 210 can lock the relative position of the socket 100. However, in actual applications, the first locking member 210 may fail to lock due to damage to some parts of itself or some parts on the male socket 10, resulting in failure of connection between the male socket 10 and the female socket 20. Therefore, in order to solve the problem that the first locking member 210 is prone to fail in locking under unexpected conditions, a slider 300 structure is provided, and a second locking member 310 is provided on the slider 300 structure. On the one hand, the second locking assembly 310 can be used to lock the plug 200 and the slider 300. On the other hand, the slider 300 is inserted on the plug 200, and the protrusion 320 on the slider 300 can support the plug 200, so that the plug 200 remains in an upright state, thereby making the plug 200 and the socket 100 more tightly locked, so that the first locking member 210 is not prone to fail in locking. In this embodiment, the first locking member 210 and the second locking member 310 can adopt a buckle structure assembly, a hook structure assembly or a clamping structure assembly, etc., which are provided according to actual usage.

[0026] The technical solution of the present invention adopts the first locking member 210 on the plug 200 and the second locking member 310 on the slider 300. The first locking member 210 locks the plug 200 and the socket 100 to achieve the first locking function of the electrical connector; and the second locking member 310 locks the plug 200 and the slider 300 to achieve the second locking function of the electrical connector; and the protrusion 330 of the slider 300 is used to support the plug 200, so that the plug 200 remains in an upright state, so that the plug 200 and the socket 100 remain in a tightly locked state. In the case of being pulled out in sequence without external force, the slider 300 is stable and the locking of the entire electrical connector will not fail due to damage to the parts; thereby making the connection between the male socket 10 and the female socket 20 of the electrical connector more firm and reliable.

[0027] Preferably, refer to Figure 2 and Figure 3 The plug 200 is a U-shaped spring piece, and the first locking piece 210 is a hook (not marked) formed by extending the U-shaped spring piece 200 in a direction away from the socket 100; the socket 100 is provided with a slot (not marked) adapted to the hook, and the hook is engaged and fixed in the slot.

[0028] Specifically, the plug 200 is configured as a U-shaped spring piece, which makes the plug 200 elastic; when the plug 200 (U-shaped spring piece 200) is inserted into the cavity 101 of the socket 100, the elastic upper and lower parts of the U-shaped spring piece 200 can be tightly held in the cavity 101, so that the U-shaped spring piece 200 is tightly plugged into the socket 100. In this embodiment, the hook includes a first hook 211 located on the top surface of the U-shaped spring piece 200 and a second hook 212 located on both sides of the side of the U-shaped spring piece 200; wherein the first hook 211 and the first slot 110 are mutually engaged, and the direction of the first hook 211 hooking is away from the socket 100, so that the horizontal displacement of the U-shaped spring piece 200 is locked; the second hook 212 located on both sides of the side of the U-shaped spring piece 200 and the second slot 120 are mutually engaged, and the direction of the second hook 212 hooking is away from the socket 100, so that the vertical displacement of the U-shaped spring piece 200 is locked, and the U-shaped spring piece 200 and the socket 100 that are plugged into one body achieve a better locking effect.

[0029] Further, refer to Figure 2 and Figure 3 The slider 300 includes a base plate 320 and a first limiting plate 340 vertically arranged on two opposite sides of the base plate 320; the U-shaped spring piece 200 is convexly provided with two second limiting plates 220 on a surface opposite to the hook, and the two second limiting plates 220 are distributed on both sides of the U-shaped spring piece 200; the second limiting plates 220 form a slide rail (not shown) on the U-shaped spring piece 200 for the base plate 320 to slide.

[0030] In order to allow the base plate 320 of the slider 300 to slide more smoothly into the U-shaped spring piece 200, a second limit plate 220 is set on the U-shaped spring piece 200, and a first limit plate 340 is also set on the base plate 320. In this way, the second limit plate 220 forms a slide rail on the U-shaped spring piece 200 for the base plate 320 to slide; the base plate 320 uses the first limit plate 340 to abut against the second limit plate 220 and slides smoothly into the U-shaped spring piece 200 along the slide rail, and the second limit plate 220 on the U-shaped spring piece 200 forms a displacement limit on the first limit plate 340 on the base plate 320.

[0031] Further, refer to Figure 2 and Figure 3 The second locking member 310 is a positioning column 310 arranged on the first limiting plate 340; the U-shaped spring sheet 200 extends to form a spring sheet button 230 on the side where the hook is set, and the spring sheet button 230 extends toward the end where the substrate is inserted; the second limiting plate 220 is provided with an anti-retraction groove 221, the positioning column 310 is clamped in the anti-retraction groove 221, and the protrusion 330 is clamped on the spring sheet button 230.

[0032] Specifically, after the U-shaped spring piece 200 and the socket 100 are inserted into each other and the first locking assembly 210 completes the first locking, the slider 300 can be pushed forward and the positioning column 310 can be inserted into the anti-retraction slot 221 on the second limiting plate 220 to lock the slider 300 inserted into the U-shaped spring piece 200. In addition, in order to further improve the connection strength between the U-shaped spring piece 200 and the socket 100, a protrusion 330 is provided on the base plate 320 of the slider 300. The protrusion 330 specifically abuts against the upper part of the U-shaped spring piece 200 to limit the compression deformation action of the U-shaped spring piece 200, so that the U-shaped spring piece 200 remains straight in the cavity 101 of the socket 100, thereby making the connection between the U-shaped spring piece 200 and the socket 100 more stable. In order to facilitate the removal of the slider 300 from the U-shaped spring piece 200, a spring button 230 is formed by extending the U-shaped spring piece 200 on the top surface toward the substrate 310. During the disassembly process, a downward vertical force can be applied to the spring button 230 to make the U-shaped spring piece 200 shrink and deform inwardly in the cavity 101 of the socket 100, and then the U-shaped spring piece 200 is pulled out of the socket 100 to complete the unlocking action.

[0033] Further, refer to Figure 2 and Figure 3 The U-shaped spring piece 200 is also provided with a third limiting plate 240 on the side opposite to the hook, and the third limiting plate 240 is arranged close to the end where the substrate 320 is inserted, and the third limiting plate 240 is distributed on both sides of the U-shaped spring piece 200 where the second limiting plate 220 is arranged, and the third limiting plate 240 and the second limiting plate 220 are arranged at intervals and form a clamping position 203; the slider 300 also includes a through groove 203 arranged on the end where the substrate 320 and the U-shaped spring piece 200 are plugged in, and the clamping plate 350 is provided with a protrusion 351 that is adapted to resist the through groove 203.

[0034] In order to prevent the substrate 320 from being inserted too much into the U-shaped spring piece 200, which would cause the locking between the slider 300 and the U-shaped spring piece 200 to fail, a third limiting plate 240 is provided on the U-shaped spring piece 200, and the third limiting plate 240 and the second limiting plate 220 are located on the same side of the U-shaped spring piece 200; in addition, the through groove 203 between the third limiting plate 240 and the second limiting plate 220 can be used for the card plate 350 at one end of the substrate 320 close to the U-shaped spring piece 200 to be inserted, and the side of the third limiting plate 240 facing the card plate 350 can limit the card plate 350, so that the substrate 320 can slide into the U-shaped spring piece 200 and stop at an effective locking distance. The protrusion 351 on the card plate 350 can further limit the position of the card plate 350 on the through groove 203, thereby ensuring that the substrate 320 stops moving at an appropriate position of the U-shaped spring piece 200.

[0035] Refer to the figure Figure 2 and Figure 3 , the socket 100 is provided with extension grooves 102 on both sides corresponding to the third limiting plate 240 for the clamping plate 350 to be exposed from the cavity 101, and the extension grooves 102 are connected with the cavity 101. Specifically, when the U-shaped spring piece 200 is inserted into the cavity 101 of the socket 100, the front end of the U-shaped spring piece 200 is inserted deeper, ensuring a tighter locking effect between the U-shaped spring piece 200 and the socket 100; therefore, the clamping plate 350 at the front end of the substrate 320 also enters the cavity 101 with the U-shaped spring piece 200. In order to avoid the protrusion 351 of the clamping plate 350 from hindering the substrate 320 from entering the cavity 101, the extension grooves 102 are provided so that the clamping plate 350 can be exposed outside the extension grooves 102 during the advancement of the substrate 320, thereby ensuring that the U-shaped spring piece 200 can smoothly enter the cavity 101 of the socket 100.

[0036] Furthermore, in order to accelerate the locking speed of the slider 300 in the curved spring sheet 200, the second limit plate 220 is further provided with a pre-slot 222 adapted to engage with the positioning column 310, the pre-slot 222 is arranged at a distance from the anti-retraction slot 221, and the pre-slot 222 is arranged away from the end of the substrate 320 inserted into the U-shaped spring sheet 200. In this way, before the slider 300 slides into the U-shaped spring sheet 200, the positioning column 310 can be pre-engaged in the pre-slot 22, and the substrate 320 can therefore temporarily stay in the slide rail of the U-shaped spring sheet 200. When the slider 300 slides into the U-shaped spring sheet 200, the positioning column 310 can shorten the distance on the slide rail and slide into the U-shaped spring sheet 200 faster.

[0037] Further, refer to Figure 2 and Figure 3 The slider 300 further includes a booster block 360 disposed on one end of the substrate 320 away from the clamping plate 350. This arrangement makes it convenient for the user to grab the booster block 360 and easily push the substrate 320 into the U-shaped spring sheet 200.
