[0004] The purpose of this utility model is to provide a patch cover with an anti-misinsertion positioning structure to solve the problem mentioned in the background art that the existing patch cover is prone to misalignment during use, which affects its use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patch cover with an anti-misinsertion positioning structure, comprising: a mounting base plate, electronic components disposed on the mounting base plate, and a patch cover body mounted on the top of the mounting base plate, further comprising: The patch cover body has a heat dissipation pad inside, and the heat dissipation pad is connected to a connecting component for heat dissipation and dust prevention on the outside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the patch cover with the anti-misinsertion positioning structure can play a role in dust prevention and heat dissipation inside the electronic components through the setting of the connecting component, and at the same time, the patch cover can be stably positioned by the setting of the limiting component to prevent it from shifting and being misinserted. With the dustproof mesh, external air enters the patch cover body through the dustproof mesh and heat dissipation pad, which can dissipate heat from the inside of the patch cover body. At the same time, the dustproof mesh can also prevent dust. The connecting rod is set at an equal angle inside the mounting outer ring, and the connecting rod is connected to the patch cover body by threads, which makes the mounting outer ring detachable.

The patch cover body is connected to the mounting base plate by means of locking the limiting rods. When the limiting rods are locked to the four corners of the mounting base plate, the patch cover body is locked to the mounting base plate when the patch cover body is placed on the top side of the mounting base plate, so as to prevent misinsertion. The positioning limit rod and the connecting gasket are connected by sliding. The inner side of the positioning limit rod is engaged with the mounting base plate. The connecting gaskets are evenly spaced on the outer side of the patch cover body. The longitudinal section of the connecting gasket is an "L" shaped structure. When the positioning limit rod is pulled outward, the connecting spring is compressed, causing the positioning limit rod to disengage from the mounting base plate. This facilitates the disassembly and removal of the patch cover body from the mounting base plate, making it convenient to repair the electronic components. Attached Figure Description

[0018] Working principle: When using this patch cap equipped with an anti-misinsertion positioning structure, firstly as follows... Figure 2 and Figure 3In this process, an electronic component 2 is mounted on the upper side of the mounting base plate 1. The electronic component 2 is placed on the upper surface of the mounting base plate 1. At the same time, a patch cover body 3 is mounted on the top of the mounting base plate 1. The patch cover body 3 is then placed on the mounting base plate 1. A heat dissipation pad 4 is provided inside the patch cover body 3, and a connecting component for heat dissipation and dust prevention is connected to the outer side of the heat dissipation pad 4. The connecting component includes a mounting outer ring 5 located on the outer side of the heat dissipation pad 4. A mounting hole 12 is opened inside the mounting outer ring 5, and a connecting rod 6 is installed inside the mounting hole 12. A dustproof mesh 7 is provided inside the mounting outer ring 5. With the dustproof net 7 in place, external air passes through the dustproof net 7 and heat dissipation pad 4 into the patch cover body 3, which can dissipate heat inside the patch cover body 3. At the same time, the dustproof net 7 can also prevent dust. When the connecting rod 6 is rotated, the connecting rod 6 is set at an equal angle inside the mounting outer ring 5, and the connecting rod 6 is connected to the patch cover body 3 by threads, which makes the mounting outer ring 5 detachable. At this time, the connecting rod 6 is disengaged from the mounting hole 12 inside the mounting outer ring 5, thereby disassembling the connecting rod 6, which makes it easy to replace and clean the mounting outer ring 5. The operation is convenient.

[0019] Specific examples Figure 1 , Figure 4 and Figure 5 In this design, limiting rods 14 are installed at the four corners of the bottom of the patch cover body 3. When the patch cover body 3 is placed on the upper side of the mounting base plate 1, the patch cover body 3 is connected to the mounting base plate 1 by the limiting rods 14 in a snap-fit ​​manner. At this time, the limiting rods 14 are stably snapped into the four corners of the mounting base plate 1, so that the patch cover body 3 is stably snapped into the mounting base plate 1, preventing misinsertion and stably positioning the patch cover body 3. Since the outer end of the patch cover body 3 is fixed with a connecting gasket 8, and the connecting gasket 8 has a positioning hole 10 inside; the connecting gasket 8 is equipped with a limiting component connected to the mounting base plate 1. The limiting component includes a positioning limiting rod 9 installed inside the connecting gasket 8, and a fixing ring 13 is fixed on the outer surface of the positioning limiting rod 9, and a nested part is provided on the outer side of the fixing ring 13. The connecting spring 11 on the surface holds the outer end of the patch cover body 3 against the outer side of the mounting base plate 1. At this time, the connecting spring 11 extends and retracts, locking the positioning limit rod 9 inside the mounting base plate 1, thereby stably installing the patch cover body 3 on the outer end of the mounting base plate 1. The positioning limit rod 9 and the connecting gasket 8 are connected in a sliding manner, and the inner side of the positioning limit rod 9 is locked and connected to the mounting base plate 1. The connecting gaskets 8 are evenly spaced on the outer side of the patch cover body 3. The longitudinal section of the connecting gasket 8 is an "L" shaped structure. When the positioning limit rod 9 is pulled outward, the connecting spring 11 is compressed, causing the positioning limit rod 9 to disengage from the mounting base plate 1, making it easy to detach the patch cover body 3 from the mounting base plate 1 for disassembly and easy to repair the electronic components 2. This is the usage method of the patch cover with anti-misinsertion positioning structure.
