[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will be more clearly described in light of the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0032] like Figure 1As shown, the embodiment provides a sleeve plate component positioning and assembling assembly, which comprises a sleeve plate clamp 1, an upper PCB plate 2, a lower PCB plate 3 and a component 4. The sleeve plate clamp 1 is annular. A supporting block 11 is inwardly protruded at the inner wall of the sleeve plate clamp 1. The lower PCB plate 3 is horizontally placed in the sleeve plate clamp 1 and supported on the supporting block 11. The component 4 is placed on the lower PCB plate 3. The upper end of the component 4 is provided with a plurality of first pins 41. The upper PCB plate 2 is placed above the component 4. The upper PCB plate 2 is provided with a plurality of first connecting holes 21 corresponding to the first pins 41 one by one. Each first pin 41 penetrates through the corresponding first connecting hole 21 to position the component 4 relative to the upper PCB plate 2. The lower end of the upper PCB plate 2 is provided with a plurality of second pins 22. The lower PCB plate 3 is provided with a plurality of second connecting holes 31 corresponding to the second pins 22 one by one. Each second pin 22 penetrates through the corresponding second connecting hole 31 to position the upper PCB plate 2 relative to the lower PCB plate 3. In this way, the component is positioned with the upper PCB through the first pins on the component, and the upper PCB plate is positioned with the lower PCB plate through the second pins on the upper PCB plate. Thus, the upper PCB plate, the component and the lower PCB plate are precisely positioned relative to each other.

[0033] In the above technical solution, the second pins 22 are bamboo joint pins. In this way, the spacing between the upper PCB plate and the lower PCB plate can be limited by the second pins.

[0034] In the above technical solution, the supporting blocks 11 are annularly and spacedly arranged on the inner wall of the sleeve plate clamp 1. The structure is simple, and the supporting effect on the lower PCB plate is good.

[0035] As shown, Figure 2 In the above technical solution, the inner hole of the sleeve plate clamp 1 cooperates with the lower PCB plate 3. In this way, the lower PCB plate does not shake when placed in the sleeve plate clamp. This is beneficial to the positioning and assembling of the component and the upper PCB plate.

[0036] As shown, Figure 1 , Figures 3-5As shown, the above technical solution includes multiple components 4, which are spaced apart between the upper PCB board 2 and the lower PCB board 3. The structure is simple. Specifically, at least one component 4 is a second component 4b, and the remaining components 4 are first components 4a. The first component 4a is placed on the lower PCB board 3. The lower PCB board 3 has a through hole 32 at the position corresponding to the second component 4b. The inside of the sleeve clamp 1 is provided with a pad 12 below the through hole 32. The second component 4b passes through the through hole 32 and is placed on the pad 12 to vertically position the second component 4b. This also meets the assembly requirements of the second component sinking relative to the lower PCB, and the assembly accuracy is high.

[0037] In this embodiment, the position of the second pin needs to avoid the pad 12, so as to prevent the second pin from hitting the pad after passing through the lower end of the lower PCB board.

[0038] like Figure 2 and Figure 6 As shown, the upper end of the support block 11 in the above technical solution is provided with a threaded hole 111, and the corresponding edge of the lower PCB board 3 is provided with an eyelet 33 aligned with the threaded hole 111. A bolt 5 that is threadedly connected to the threaded hole 111 on the corresponding support block 11 passes through the eyelet 33 to fasten the lower PCB board 3 to the support block 11. In this way, the lower PCB board can be fastened to the support block by bolts, which makes the limiting effect of the lower PCB board in the sleeve fixture better.

[0039] like Figures 2-5 As shown, in the above technical solution, the pad 12 extends to be integrally formed with the sleeve clamp 1, which has a simple structure and is conducive to improving the installation accuracy of the second component.

[0040] The sleeve clamp 1 described in the above technical solution is made of plastic or metal, and has a simple structure and good durability.

[0041] The sleeve clamp 1 described in the above technical solution is made of aluminum alloy, which is durable and relatively lightweight.

[0042] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form; any person skilled in the art can smoothly implement the present application according to the drawings shown in the specification and the above description; however, any person skilled in the art can make slight changes, modifications and equivalent changes of the present application within the scope of the technical scheme of the present application, and the equivalent embodiments of the present application are still within the protection scope of the technical scheme of the present application.
