Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to an anti-collision multilayer PCB board. Background Technology

[0002] A PCB, or Printed Circuit Board, is a fundamental material used to connect electronic components. It connects and supports various electronic components (such as resistors, capacitors, and chips) through conductive paths. PCBs play a crucial role in modern electronic devices and are widely used in various products, such as mobile phones, computers, home appliances, and automotive electronics.

[0003] After the existing PCB boards are manufactured, they often need to be transported and handled. In order to improve transportation efficiency, the manufactured PCB boards are often stacked and stored together. During transportation and storage, the PCB boards are often bumped due to the transportation distance and other factors. This bumping can cause collisions between the stored PCB boards. In order to avoid these collisions from affecting the PCB boards, a lot of packaging materials are needed to protect the PCB boards from impacts. This kind of packaging is not only time-consuming and labor-intensive, but also has a relatively high material cost, so it has certain shortcomings.

[0004] In conclusion, it is necessary to invent a collision-resistant multilayer PCB board. Utility Model Content

[0005] Therefore, this utility model provides an anti-collision multilayer PCB board to solve the problem that in order to avoid these collisions from affecting the circuit board, personnel need to consume a lot of packaging materials to protect the circuit board from collisions. This packaging is not only time-consuming and labor-intensive, but also has a relatively high material cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision-resistant multilayer PCB board, including a circuit board layer, a component layer installed on one side of the outer wall of the circuit board layer, and a collision-resistant component provided on the outer side of the circuit board layer;

[0007] The anti-collision component includes a base plate and an outer anti-collision strip. The base plate is located below the circuit board layer to support the circuit board layer, and the outer anti-collision strip is located on the outer side of the circuit board layer to protect the edge of the circuit board layer.

[0008] Preferably, the outer wall of the circuit board layer is provided with through holes on both the upper and lower sides for screws to pass through during installation, and the top of the outer wall of the storage base plate is provided with positioning posts at the positions corresponding to the through holes.

[0009] Preferably, the top of the outer wall of the storage base plate is provided with threaded slots, and the multiple threaded slots are evenly arranged in an array. The bottom of the outer wall of the positioning column is fixed with a baffle, and the top of the outer wall of the positioning column is integrally fixed with an upper threaded head. The outer wall of the upper threaded head is threaded with a fixing bolt.

[0010] Preferably, the bottom of the outer wall of each baffle is integrally fixed with a bottom thread head, the outer wall of the bottom thread head is threadedly connected to the inner wall of the threaded slot, and the outer wall of the circuit board layer is slidably connected to the outer wall of the positioning post through a through hole.

[0011] Preferably, a supporting rubber cylinder is provided on the outer wall of the positioning column and located between the two circuit board layers. The upper and lower sides of the outer wall of the rubber cylinder are slidably connected to the outer wall of the positioning column through through holes.

[0012] Preferably, the upper and lower circuit board layers are arranged in a way that the component layers face each other, and a protective component pad is provided between the upper and lower circuit board layers. The outer wall of the component pad is provided with storage grooves on the upper and lower sides and at positions corresponding to the component layers.

[0013] Preferably, all four outer anti-collision strips are disposed at the outer wall side edge of the circuit board layer, and each outer anti-collision strip has a placement slot for connection at the end near the circuit board layer.

[0014] Preferably, a buffer groove is provided on the inner side of the outer anti-collision strip and on the side away from the circuit board layer, and an anti-collision pad is provided on the end of the outer anti-collision strip away from the bottom plate.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, personnel can protect the circuit board layers by fixing external anti-collision strips at their edges. When transporting the circuit board layers, personnel can stack the circuit board layers on the base plate and separate them with component protective pads and rubber supports. This not only fixes the circuit board layers but also prevents them from shaking and colliding. The exposed edges are then protected by the external anti-collision strips, thus preventing damage to the circuit board layers from collisions. This also eliminates the need for factories to use excessive packaging materials on the circuit board layers, making it more convenient for personnel to use. Attached Figure Description
