[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Example

[0030] A vertical plate hidden connector, such as Figure 1-5 As shown, it includes a fixing sleeve 1 embedded in the inside of the plate body, a telescopic clamping member 2 arranged inside the fixing sleeve 1, and a locking block 3 fixed to the inside of another plate body by screws and aligned with the fixing sleeve 1 to cooperate with the telescopic clamping member 2.

[0031] The fixing sleeve 1 includes a first fixing sleeve shell 11 and a second fixing sleeve shell 12 that is fixed to the first fixing sleeve shell 11 and cooperates with the first fixing sleeve shell 11 to assemble the telescopic clamping member 2.

[0032] The telescopic card assembly 2 includes a telescopic card assembly body 21 assembled by cooperating with the first fixed sleeve 11 and the second fixed sleeve 12, cylinders 22 integrally formed on both sides of the telescopic card assembly body 21, a rectangular groove 23 provided inside the telescopic card assembly body 21, a lock head 24 located at the top of the telescopic card assembly body 21 and connected to the telescopic card assembly body 21 through a narrow neck, and a spring member 25 arranged inside the rectangular groove 23 and cooperating with the first fixed sleeve 11 and the second fixed sleeve 12 to push out the telescopic card assembly body 21.

[0033] The first fixed housing 11 includes a housing body 111, an arc-shaped cavity 112 provided inside the housing body 111 for accommodating the cylinder 22, a spring abutment seat 113 integrally formed at the lower end of the housing body 111, a base 114 integrally formed near the bottom of the housing body 111 for abutting the telescopic card-mounting body 21, and a side groove 115 integrally formed at the upper end of the housing body 111 for accommodating the lock head 24.

[0034] The side of the housing body 111 is integrally formed with an upwardly inclined anti-slip fin 1111. Specifically, the anti-slip fin 1111 can prevent the fixing sleeve 1 from being easily pulled out after being embedded in the plate body.

[0035] The spring abutment seat 113 is provided with a plug connector 1131 and a plug slot 1132 .

[0036] The structure of the second fixing housing 12 is consistent with that of the first fixing housing 11 .

[0037] Specifically, when the fixed sleeve 1 and the telescopic clip 2 are assembled, the spring abutment of the first fixed sleeve 11 is located in the rectangular groove 23 inside the telescopic clip body 21, and then the spring member 25 is inserted so that the upper end of the spring member 25 abuts the inner top of the rectangular groove 23, and the lower end first abuts the spring abutment of the first fixed sleeve 11, and then the spring abutment of the second fixed sleeve 12 is also placed in the rectangular groove 23 inside the telescopic clip body 21 and aligned with the spring abutment of the first fixed sleeve 11. By squeezing the first fixed sleeve 11 and the second fixed sleeve 12, the plug connectors and plug slots on the two spring abutment seats are correspondingly plugged in, and the assembly is completed, which can cooperate with the assembly of the telescopic clip 2.

[0038] It should be further explained that after the spring abutment seat of the first fixed sleeve 11 and the spring abutment seat of the second fixed sleeve 12 are correspondingly plugged into each other through the plug connector and the plug slot, not only can the first fixed sleeve 11 and the second fixed sleeve 12 be fixed to form the fixed sleeve 1, but the two spring abutment seats can also support the spring member 25, making it convenient for the spring member 25 to lift the telescopic card body 21 for reset.

[0039] A spring fixing column 231 integrally formed with the telescopic card body 21 is provided at the inner top of the rectangular groove 23 . Specifically, the spring 25 is sleeved in the spring fixing column 231 to prevent the spring 25 from deviating and loosening.

[0040] The lock block 3 comprises an elongated lock block body 31, a connecting slot 32 in the middle of the lock block body 31 for engaging the lock head 24, and a pressure finger 33 located at one end of the connecting slot 32 and integrally formed with the lock block body 31. Mounting holes 311 are provided at both ends of the lock block body 31. Specifically, after the lock block 3 is embedded within the plate, screws are driven through the mounting holes 311 into the plate to effectively secure the lock block 3. A wide channel 321 is provided at the end of the connecting slot 32 closest to the pressure finger 33, while a narrow channel 322 is provided at the end of the connecting slot 32 further away from the pressure finger 33.

[0041] Specifically, the width of the wide groove 321 is greater than the width of the lock head 24, so the lock head 24 can be separated from the lock block body 31 from the wide groove 321, and the width of the narrow groove 322 is greater than the narrow neck width of the lock head 24 and smaller than the width of the lock head 24, so when the narrow neck of the lock head 24 slides into the narrow groove 322, the lock head 24 is connected and locked to the lock block body 31.

[0042] In this embodiment, the pressing fingers 33 are arranged at an angle of 45°.

[0043] like Figure 6As shown, the spring member 25 pushes up the telescopic card body 21 so that the lock head 24 is pushed into the wide groove 321 . At this time, the lock head 24 is not locked with the lock block 3 .

[0044] like Figure 7 As shown, combined with Figure 6 , the fixed sleeve 1 drives the telescopic card assembly 2 to slide in the direction a. At this time, when the narrow neck of the lock head 24 slides from the wide groove 321 into the narrow groove 322, the telescopic card assembly 2 is connected and locked with the locking block 3, completing the assembly;

[0045] like Figure 8 As shown, combined with Figure 6-7 The fixing sleeve 1 drives the telescopic card assembly 2 to slide in direction b, and the narrow neck of the lock head 24 slides out of the narrow groove 322 and into the wide groove 321. When the vertical plate is assembled, due to the extrusion of the plate body and the lock head 24 is still located in the wide groove 321, the telescopic card assembly 2 cannot be separated from the lock block 3. Therefore, the fixing sleeve 1 continues to drive the telescopic card assembly 2 to slide in direction b. At this time, the lock head 24 contacts the pressing finger 33 set at a 45° angle, and is gradually compressed downward into the fixing sleeve 1 under the pressure of the pressing finger 33 until it is completely immersed in the fixing sleeve 1. The lock head 24 is completely separated from the wide groove 321, and the disassembly is completed.

[0046] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
