Description

Technical Field

[0001] This utility model relates to the field of electronic device installation technology, specifically a back-end board connection and fixing device. Background Technology

[0002] In the field of electronic equipment such as servers, industrial control computers, and communication equipment, the back-end board is the core connecting component between the device and external interfaces (such as data interfaces, power interfaces, and signal interfaces). The accuracy and stability of its connection and fixation with the main body of the device directly determine the signal transmission efficiency, heat dissipation performance, and long-term operational reliability of the device.

[0003] When the back-end plate is actually connected and fixed, multiple sets of symmetrically distributed bolt holes are usually set on the edge or four corners of the back-end plate. Corresponding threaded holes are opened on the equipment frame or main frame. During installation, the operator needs to observe with the naked eye or use a ruler to repeatedly measure the distance between the edge of the back-end plate and the equipment reference surface, and adjust the position of the back-end plate to calibrate the hole position. If the bolt tightening sequence is not correct, the back-end plate may be slightly deformed due to uneven force, or there may be a problem of skewed fixing after the hole position is forcibly aligned. Even if all the bolts are finally tightened, there will still be a certain positional deviation of the back-end plate, which directly affects the subsequent interface docking accuracy. In severe cases, it may cause wear of interface pins or interruption of signal transmission, which is difficult to control in terms of precision and easy to generate assembly errors.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-4 As shown, this utility model is a rear end plate connection and fixing device, comprising: The fixing components include a base 1, a vertical plate 11, a support rod 12, a spring 13, a slot 14, a plug 16, and a positioning block 19. The base 1 is located on one side of the rear end plate, the vertical plate 11 is located on both sides of the outer surface of the base 1, the support rod 12 is fixed to the upper and lower parts of both sides of the outer surface of the base 1, the spring 13 is wound around the outer surface of the support rod 12, the positioning block 19 is fixed to the upper and lower parts of one side of the vertical plate 11, the slot 14 is opened at one end of the outer surface of the base 1, and the plug 16 is fixed at one end of the rear end plate and is inserted into the slot 14. The insert 16 and slot 14 are precisely matched. During the insertion process, the lateral and longitudinal offset of the rear end plate is automatically limited, providing basic guidance for the positioning block 19 to engage. The spring 13 generates continuous squeezing force on the positioning block 19 in the pre-compressed state. When the insert 16 is inserted into the interior of the slot 14, the spring 13 instantly rebounds and pushes the positioning block 19 to be simultaneously embedded in the two sets of positioning slots, realizing zero-deviation fixation of the rear end plate and the base 1. This fully meets the precise docking requirements of the rear end plate and the internal module interface pins, completely avoids signal transmission failures caused by improper manual adjustment, and completely eliminates assembly errors.

[0019] The interior of the upright plate 11 is provided with a hole 18, which is slidably connected to the outside of the support rod 12; When the spring 13 generates elastic force and exerts a squeezing force on the positioning block 19, the hole 18 will slide synchronously outside the support rod 12 with the buffer of the spring 13.

[0020] The outer surface of the base 1 has two positioning grooves 15 on both sides, and the insertion block 16 has a positioning groove 17 on one side. The positioning block 19 is inserted and connected inside the positioning groove 15 and the positioning groove 17. The rear end plate is completely fixed by bidirectional locking of positioning block 19.

[0021] A support frame 21 is fixedly connected to one side of the outer surface of the support rod 12, and one side of the outer surface of the support frame 21 is fixed to the outside of the base 1. The upper and lower parts of one end of the outer surface of the base 1 are provided with slots 22, and the upper and lower parts of one end of the rear end plate are provided with a retaining plate 23, which is engaged in the inside of the slot 22. The slot 22 limits the vertical displacement of the rear end plate by the upper and lower limit of the card plate 23. At the same time, the cooperation between the card plate 23 and the slot 22 provides initial guidance for the rear end plate, ensuring that the rear end plate as a whole maintains a parallel attitude with the equipment reference plane, avoiding subsequent positioning deviations caused by the tilt of the rear end plate in traditional installation.

[0022] Working principle: At the initial stage of installation, the operator holds the rear end plate and pushes the upper and lower clamping plates 23 on the rear end plate into the slots 22 on the base 1 in parallel with the opening direction of the slots 22 until the clamping plates 23 are fully embedded in the bottom of the slots 22. The operator continues to push the rear end plate so that the insert block 16 is inserted into the slot 14 along the opening direction. When the insert block 16 is inserted to the preset depth, the arc-shaped contact surface of the positioning block 19 is just aligned with the opening of the positioning slot 15 and the positioning slot 27. The spring 13 loses the pressure restriction of the inclined surface of the insert block 16 and instantly rebounds to release the stored force, pushing the positioning block 19 to be embedded into the positioning slot 15 and the positioning slot 27 simultaneously.

[0023] This step uses the card plate 23-card slot 22 to restrict the vertical movement of the rear end plate, the insertion block 16-slot 14 to restrict the horizontal movement of the rear end plate, and the positioning block 19-positioning slot one 15 and positioning slot two 17 to restrict the front-back movement of the rear end plate, forming a six-way limiting structure to prevent the rear end plate from becoming loose in any direction during equipment operation. Continuous elastic force: Spring 13 always applies axial pressure to positioning block 19 (elastic force value is stable at 8-10N), so that positioning block 19 fits tightly with the inner wall of positioning groove 15 and positioning groove 17. Even if the equipment undergoes slight deformation due to thermal expansion and contraction or vibration, the elastic force of spring 13 can compensate for the gap in real time, ensuring that positioning block 19 is always in the locked state, realizing zero-deviation fixation of the rear end plate and the base 1, fully meeting the precise docking requirements of the rear end plate and the internal module interface pins, completely avoiding signal transmission failures caused by improper manual adjustment, and completely eliminating assembly errors.

[0024] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The reinforcing components include a locking frame 31, a guide rod 32, and a guide ring 33. The guide rod 32 is fixed to the top and bottom of the base 1, and the guide ring 33 is slidably connected to the outside of the guide rod 32 and its bottom is fixed to the top of the locking frame 31. The locking frame 31 is snapped into the top of the upright plate 11. The upper locking bracket 31 is snapped to the top edge of the upright plate 11, and the inner wall of the latch is tightly fitted with the top surface of the upright plate 11, restricting the upward displacement of the upright plate 11. The lower locking bracket 31 is snapped onto the bottom edge of the upright plate 11, and the inner wall of the latch is tightly fitted to the bottom surface of the upright plate 11, restricting the downward displacement of the upright plate 11.

[0025] The outer surface of the guide rod 32 is threaded with a fastening ring 35, which is fastened to the outside of the locking frame 31; The fastening ring 35 locks the locking frame 31 in place by means of the threaded self-locking property, preventing the locking frame 31 from sliding along the guide rod 32 due to vibration during equipment operation.

[0026] A limit plate 34 is fixedly connected to the top of the guide rod 32.

[0027] Working principle: When the upper and lower guide rings 33 are attached to the two sides of the base 1 respectively, the operator pushes the upper and lower guide rings 33 simultaneously with both hands, so that the guide rings 33 slide up and down along the guide rod 32, driving the upper and lower locking frames 31 to move towards the upright plate 11. The upper locking frame 31 is engaged with the top edge of the upright plate 11, and the lower locking frame 31 is engaged with the bottom edge of the upright plate 11. After the locking frame 31 is engaged with the upright plate 11, the operator rotates the fastening ring 35 by hand, so that it moves downward along the external thread of the guide rod 32 until the fastening ring 35 completely presses against the top plane of the upper locking frame 31.

[0028] This step avoids the risk of spring 13 loosening through multiple fixing structures, and achieves efficient, precise and long-term connection and fixation of the rear end plate.
