Abstract
Description
Technical Field
[0001] This utility model relates to circuit board technology, and more specifically, to anti-collision circuit boards. Background Technology
[0002] Circuit boards are the core components of electrical equipment, used to support and connect electronic components to achieve functions such as the transmission of electrical signals. Circuit boards can be divided into single-layer circuit boards and multi-layer circuit boards. The difference is that multi-layer circuit boards are composed of two or more single-layer circuit boards. Compared with single-layer circuit boards, multi-layer circuit boards can realize more complex circuit functions.
[0003] Multilayer circuit boards typically have round holes near the corners for screws to pass through. This design reduces the impact of the screws on electronic components. During transportation, multilayer circuit boards may be bumped at the corners, which can cause them to separate and damage the internal circuitry.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-collision circuit board.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-collision circuit board, including a circuit board body, a circular hole provided on the circuit board body near the corner of the circuit board body, an anti-collision sleeve covering the corner of the circuit board body, and a connector detachably connected to the circular hole on the anti-collision sleeve.
[0007] The present invention is further configured such that: there is a gap between the anti-collision sleeve and the peripheral wall of the circuit board body, and the anti-collision sleeve is provided with an adhesive strip for contacting the peripheral wall of the circuit board body.
[0008] The present invention is further configured such that: the connecting member includes a circular sleeve fixedly connected to the anti-collision sleeve and an annular protrusion provided on the outer peripheral wall of the circular sleeve, and an annular groove for the annular protrusion to be inserted is provided on the inner peripheral wall of the circular hole.
[0009] The present invention is further configured such that: the anti-collision sleeve includes a step fixedly connected to the circular sleeve, the step being used to abut against the side wall of the circuit board body.
[0010] The present invention is further configured such that: the step protrudes from the surface of the anti-collision sleeve, and the step only abuts against the circuit board body at the edge of the circular hole.
[0011] The present invention is further configured such that: a groove is provided on the peripheral wall of the step, and the groove is connected to the side wall of the step facing the circuit board body.
[0012] In summary, this utility model has the following beneficial effects:
[0013] During the transportation of multilayer circuit boards, when the corners of the circuit board collide with other objects, the anti-collision sleeve replaces the circuit board body in directly impacting the object. The anti-collision sleeve absorbs part of the impact energy, reducing damage to the corners of the circuit board body and minimizing the separation of the multilayer circuit board at the corners. When installing the circuit board, the anti-collision sleeve can be separated from the circuit board body by removing the connector from the round hole, avoiding unnecessary trouble caused by the presence of the anti-collision sleeve during the installation of the multilayer circuit board.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Anti-collision circuit boards, such as Figure 1 and Figure 2As shown, the circuit board includes a circuit board body 1, with circular holes 2 located near the corners of the circuit board body 1. A shock-absorbing sleeve 3 covers the corners of the circuit board body 1, and the shock-absorbing sleeve 3 has a connector detachably connected to the circular hole 2. During the transportation of the multi-layer circuit board, when the corners of the circuit board body 1 collide with other objects, the shock-absorbing sleeve 3 directly impacts the objects instead of the circuit board body 1, absorbing some of the impact energy and reducing damage to the corners of the circuit board body 1, thus minimizing the separation of the multi-layer circuit board at the corners. In order to prevent the installation of circuit boards, the anti-collision sleeve 3 can be separated from the circuit board body 1 by removing the connector from the round hole 2. This avoids unnecessary trouble caused by the presence of the anti-collision sleeve 3 in the installation of multi-layer circuit boards. Both the anti-collision sleeve 3 and the connector are made of TPU material. TPU material has good toughness and impact resistance. The anti-collision sleeve 3 made of this material can provide good protection for the corners of the circuit board body 1. The connector made of this material can deform when the anti-collision sleeve 3 is removed, which facilitates the separation of the anti-collision sleeve 3 from the circuit board body 1.
[0020] like Figure 2 and Figure 3As shown, there is a gap between the anti-collision sleeve 3 and the peripheral wall of the circuit board body 1. An adhesive strip 4 is attached to the anti-collision sleeve 3 to abut against the peripheral wall of the circuit board body 1. The existence of the gap allows the anti-collision sleeve 3 to deform to a certain extent when impacted, reducing the possibility of the anti-collision sleeve 3 directly transmitting the impact force to the peripheral wall of the circuit board body 1. Since the adhesive strip 4 abuts against both the peripheral wall of the circuit board body 1 and the anti-collision sleeve 3, the adhesive strip 4 can effectively maintain the shape of the gap. In addition, the adhesive strip 4 can effectively absorb the impact force, further mitigating the impact force transmitted from the anti-collision sleeve 3 to the circuit board body 1. To reduce the impact force and enhance the protection of the circuit board body 1 by the anti-collision sleeve 3, the connector includes a circular sleeve 5 fixedly connected to the anti-collision sleeve 3 and an annular protrusion 6 provided on the outer peripheral wall of the circular sleeve 5. An annular groove 7 for the annular protrusion 6 to be inserted is provided on the inner peripheral wall of the circular hole 2. The outer diameter of the circular sleeve 5 is equal to the diameter of the circular hole 2. A deformation groove is provided on the circular sleeve 5. When disassembling the connector, by applying a force to the circular sleeve 5 that moves away from the circular hole 2, the annular protrusion 6 is caused to deform under the action of the force. The opening of the deformation groove is conducive to the deformation of the annular protrusion 6, making it easier for the annular protrusion 6 to disengage from the annular groove 7, thus limiting the connection of the connector. The gap disappears, allowing the connector to be disengaged from the circular hole 2, thus separating the anti-collision sleeve 3 from the circuit board body 1. The anti-collision sleeve 3 includes a step 8 fixedly connected to the circular sleeve 5. The step 8 abuts against the side wall of the circuit board body 1. The step 8 improves the connection stability between the anti-collision sleeve 3 and the circuit board body 1, preventing the circular sleeve 5 from sliding in the circular hole 2 during transportation. The step 8 protrudes from the surface of the anti-collision sleeve 3 and only abuts against the edge of the circuit board body 1 at the edge of the circular hole 2. This design leaves a gap between the remaining part of the anti-collision sleeve 3 (excluding the step 8) and the side wall of the circuit board body 1. The gap ensures the stability of the connection between the anti-collision sleeve 3 and the circuit board body 1, while also reducing the contact area between the anti-collision sleeve 3 and the circuit board body 1, thus reducing the damage to the circuit board body 1 when the anti-collision sleeve 3 is impacted. A groove 9 is provided on the peripheral wall of the step 8, which is connected to the side wall of the step 8 facing the circuit board body 1. The groove 9 allows a fingernail to be inserted into it to apply a pulling force that moves away from the circular hole 2 when disassembling the anti-collision sleeve 3. This force is transmitted to the annular protrusion 6 through the step 8 and the circular sleeve 5, allowing the annular protrusion 6 to come out of the annular groove 7, which facilitates the disassembly of the anti-collision sleeve 3.

All technical solutions falling within the scope of this utility model's concept are protected.
