Description

Technical Field

[0001] The utility model relates to the field of backboards, in particular to a backboard with a precise installation structure. Background Art

[0002] Backplanes have always been a specialized product in the PCB manufacturing industry. Backplanes are thicker and heavier than conventional PCBs, and their heat capacity is correspondingly larger. Given that the backplane cools slowly, the length of the reflow oven needs to be lengthened, and forced air cooling is required at the exit to reduce the backplane temperature to a safe level for operation.

[0003] However, the prior art has the following defects:

[0004] The backplane is a plate or frame installed on the back of the device. The existing backplane cannot completely fit the device during installation. After installation, a gap is easily left between the two, resulting in a loose connection and easy loosening. Utility Model Content

[0005] The purpose of the utility model is to provide a back plate with a precise installation structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a back panel with a precision mounting structure, comprising a back panel body, a first groove is provided on the top of the back panel body, and a clamping assembly is provided in the middle of both sides of the inner wall at the bottom of the first groove, and a clamping slot is formed between the clamping assembly and the two side panels of the back panel body, and a plurality of first threaded through holes are evenly provided at the bottom of the clamping slot, and sealing gaskets are bonded to the inner walls of the side panels around the back panel body, and a plurality of fourth threaded through holes are evenly provided on the top side panel and the bottom side panel of the back panel body.

[0007] The above technical solution is adopted, in which a first groove is opened in the back panel, so that the back panel can be mounted on the outside of the frame, which can prevent a gap between the back panel and the frame and prevent dust from entering. The side panels on both sides of the frame can be snapped into the slots to ensure precise installation, making the connection tight, easy to position, and preventing loosening and falling off.

[0008] A second groove is provided in the middle of the inner wall at the bottom of the first groove, and a plurality of ventilation holes are evenly provided on the second groove, and the ventilation holes are rectangular in shape.

[0009] By adopting the above technical solution, the second groove of the solution can ensure that there is a gap between the back of the back plate and the parts inside the frame to avoid squeezing and colliding with the internal parts. The ventilation holes can play a role in ventilation and heat dissipation to prevent the internal temperature of the frame from being too high.

[0010] A baffle is fixedly mounted on the top of one end of the ventilation hole away from the second groove, the cross-section of the baffle is in a "7" shape, and the baffle is covered on the outside of the ventilation hole.

[0011] By adopting the above technical solution, the "7"-shaped baffle is located on the outside of the ventilation hole, which can prevent dust from entering the interior of the frame through the ventilation hole and avoid damage to internal parts.

[0012] The clamping assembly includes a connecting plate and a clamping block, the bottom of one side of the clamping block is fixedly connected to one side of the connecting plate, second threaded through holes are opened at both ends of the connecting plate, a plurality of third threaded through holes are opened correspondingly on both sides of the first groove, the third threaded through holes are opened correspondingly to the second threaded through holes, the third threaded through holes are threadedly connected to the second threaded through holes by screws, and sealing gaskets are bonded to the inner walls of the first threaded through holes, the second threaded through holes, the third threaded through holes and the fourth threaded through holes.

[0013] By adopting the above technical solution, the clamping assembly is threadedly connected to the inner wall of the bottom of the first groove, which is easy to disassemble and can be adjusted in position according to the thickness of the frame side plate to ensure the precision of installation.

[0014] The back panel body is provided with a welding layer, a solder resist layer, an insulating layer, a reinforcement layer and a weather-resistant layer in sequence from the inside to the outside. The welding layer is a thin steel plate, and the inner wall of the welding layer is coated with polyurethane enamel.

[0015] By adopting the above technical solution, the welding layer of the solution is easy to be welded and installed with the parts or circuits inside the frame, and the polyurethane enamel has good resistance and plays a protective role on the inner side of the welding layer.

[0016] Green ink is coated on the solder resist layer, the insulating layer is made of a PVC plastic plate, and the reinforcing layer is woven from a plurality of metal wires.

[0017] By adopting the above technical solution, the green ink cannot be welded, which can prevent the back plate from being damaged during welding of the welding layer. The insulating layer plays an insulating role, and the reinforcing layer improves the strength of the back plate structure and extends the service life of the back plate.

[0018] The material of the weather-resistant layer is polyvinylidene fluoride, and the welding layer, solder mask layer, insulating layer, reinforcement layer and weather-resistant layer are bonded together by UV glue.

[0019] By adopting the above technical solution, the polyvinylidene fluoride has good durability, high mechanical strength, resistance to harsh environmental conditions such as acid and alkali, and good chemical stability. The layers of the structure are bonded by UV glue and are tightly connected.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] A snap-fitting assembly is provided in the middle of both sides of the inner wall at the bottom of the back panel body. The snap-fitting assembly is threadedly connected to the back panel body and is detachable. A slot is formed between the snap-fitting assembly and both sides of the back panel body. The width of the slot can be adjusted according to the thickness of the frame side panel so that both sides of the frame are just snapped into the slot to ensure installation precision.
