Description

Technical Field

[0001] The utility model belongs to the field of decoder boards and relates to a decoder board with a protective structure. Background Art

[0002] A decoder board is a device that can output switch signals when working, and is often used in system integration. Some existing decoder boards use integrated circuit boards, and various signal transmission interfaces are installed on both sides of the boards. The electronic components in the middle are often exposed to the outside, which can easily cause collisions and damage to the electronic components during transportation. Some decoder boards use integrated circuit boards with a protective cover installed on the surface. The protective cover is usually screwed onto the board by screws. During maintenance, the protective cover needs to be repeatedly disassembled and assembled, which is a cumbersome process and is less convenient to use.

[0003] Therefore, the utility model provides a decoder board with a protective structure to solve the above problems. Utility Model Content

[0005] As a preferred solution of the utility model, semicircular grooves are respectively provided on the side walls of the protective cover on the front side of the T-shaped clamping block, and a tension spring fixing block is fixedly arranged at the front end of the semicircular groove, and the tension spring fixing block is fixedly connected to the front end of the tension spring; by providing the semicircular grooves, it is convenient to install the left and right tension springs therein.

[0006] As a preferred solution of the utility model, the left and right inner walls of the rear protective cover are respectively provided with T-shaped sliding grooves matching the left and right T-shaped blocks; such a design can ensure that the front protective cover can slide back and forth inside the rear protective cover, while ensuring the stability between the two.

[0007] As a preferred solution of the utility model, T-shaped blocking blocks are fixedly provided at the front ends of the left and right side walls of the rear protective cover, and the T-shaped blocking blocks are fixedly connected to the rear end of the tension spring.

[0008] As a preferred solution of the utility model, the front side wall and the upper side wall of the front side protective cover and the rear side wall and the upper side wall of the rear side protective cover are evenly provided with heat dissipation holes respectively; by providing the heat dissipation holes, it is convenient for the heat dissipation fan to discharge the heat emitted by the electronic components on the decoding board through the heat dissipation holes.

[0009] As a preferred solution of the utility model, a cooling fan is installed in the middle slot of the upper side wall of the rear protective cover.

[0010] The beneficial effects of the utility model are as follows: by sliding the front protective cover into the rear protective cover, and cooperating with the tension spring to elastically connect the two, the protective structure can be quickly installed or removed from the decoder board body, avoiding the tediousness of maintenance personnel to repeatedly tighten the screws, improving the maintenance efficiency of maintenance personnel, and improving the editability of use. At the same time, the protective structure can effectively avoid damage to the electronic components on the decoder board body caused by external force collision. In addition, during use, in conjunction with the cooling fan, the air flow between the protective structure and the decoder board body can be accelerated, avoiding dust accumulation while accelerating heat dissipation.
