[0002] To protect personal safety during maintenance or to provide timely feedback to the vehicle computer on the coordination status of the box and cover when an abnormality occurs in the cover, micro switches are usually installed on the high-voltage box of new energy electric vehicles.

[0003] Currently, microswitches in high-voltage boxes typically require brackets and screws / nuts to be fixed to the enclosure. Existing products, such as CN202322102910.8, use a protrusion added to the enclosure wall, with a bracket added to the protrusion to fix the microswitch to the bracket, which is then fixed to the enclosure (as shown in Appendix 1 of the instruction manual). This fixing method not only increases the weight of the enclosure and the number of parts, but also increases assembly time and complexity, thus increasing costs. Therefore, the microswitch fixing solution provided by this utility model is of great significance in addressing the above problems. Utility Model Content

The micro switch can be initially fixed by the cooperation between the buckle and the through hole, and the micro switch can be further fixed by the cooperation between the hanging ear and the slot. The boss can hold the micro switch to prevent it from moving downward, thus ensuring the fixation of the micro switch in three directions and effectively avoiding displacement and deflection after installation. Compared with the existing fixing solutions, it can greatly reduce the number of parts to reduce costs, while also effectively reducing weight and increasing assembly efficiency. In summary, it solves the problems in the background technology.

The top inner wall of the first spring is provided with a buckle, and both the first spring and the second spring are provided with a slot. The insulating bracket is provided with a boss, which is located between a pair of first springs.

[0008] The micro switch has a through hole and has lugs on both sides.

[0009] Furthermore, the spacing between the pair of first spring contacts and the pair of second spring contacts is equal to the width of the micro switch.

[0010] Furthermore, the buckle has a circular cross-section, and its diameter is equal to the diameter of the through hole.

[0011] Furthermore, the cross-section of the ear is circular with chamfered edges, the slot is n-shaped with an arc-shaped top, and the width of the slot is equal to the diameter of the ear.

[0012] The present invention has the following advantages over the prior art:

[0013] (1) When using the micro switch fixing scheme of this utility model, the micro switch can be initially fixed by the cooperation between the buckle and the through hole, and the micro switch can be fixed in a second way by the cooperation between the hanging ear and the slot.

[0027] Please see Figure 1-4 As shown, a micro switch fixing scheme of the present invention includes an insulating bracket 1 and a micro switch 2;

[0028] The insulating bracket 1 is made of insulating materials such as plastic and can be directly processed by injection molding and fixed on the high voltage box. The insulating bracket 1 is provided with a first spring 3 and a second spring 4 on both sides. The first spring 3 and the second spring 4 are both made of soft plastic and are elastic. When they are squeezed, they will deform to a certain extent. The top inner wall of the first spring 3 is provided with a buckle 5, and the first spring 3 and the second spring 4 are both provided with a slot 6. The insulating bracket 1 is provided with a boss 7, which is located between a pair of first springs 3. When the micro switch 2 is fixed on the insulating bracket 1, the boss 7 can fit against the bottom of the micro switch 2 to play a limiting role, thereby holding the micro switch 2 to prevent it from moving downward.

[0029] The micro switch 2 has a through hole 8, and both sides of the micro switch 2 are provided with lugs 9.

[0030] The spacing between the pair of first springs 3 and the pair of second springs 4 is equal to the width of the micro switch 2. When the micro switch 2 is fixed on the insulating bracket 1, the pair of first springs 3 and the pair of second springs 4 can return to their original state and fit against both sides of the micro switch 2 to clamp the micro switch 2 and prevent the micro switch 2 from wobbling left and right.

[0031] The buckle 5 has a circular cross-section, and its diameter is equal to that of the through hole 8. When the micro switch 2 is installed in the insulating bracket 1, it will come into contact with the buckle 5. At this time, the buckle 5 can push the pair of first spring pieces 3 to both sides and cause them to deform slightly until the buckle 5 is inserted and fits into the corresponding through hole 8. Thus, the micro switch 2 can be initially fixed by the mutual cooperation between the buckle 5 and the through hole 8.

[0032] The cross-section of the lug 9 is circular with chamfered edges. The slot 6 is n-shaped with an arc-shaped top. The width of the slot 6 is equal to the diameter of the lug 9. When the micro switch 2 is installed in the insulating bracket 1, the lug 9 can push the pair of second spring pieces 4 to both sides and cause them to deform slightly until the lug 9 is inserted and fits into the corresponding slot 6. Thus, the micro switch 2 can be fixed a second time through the cooperation between the lug 9 and the slot 6 to prevent the micro switch 2 from shifting or deflecting.

[0033] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0034] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0035] The working principle of this utility model is as follows:

[0036] In use, the micro switch 2 can be installed onto the insulating bracket 1. During installation, the micro switch 2 will contact the buckle 5. At this time, the buckle 5 can push the pair of first spring contacts 3 to both sides, causing slight deformation until the buckle 5 is inserted and fits into the corresponding through hole 8. Thus, the micro switch 2 is initially fixed through the cooperation between the buckle 5 and the through hole 8. Simultaneously, the hook 9 can push the pair of second spring contacts 4 to both sides, causing slight deformation until the hook 9 is inserted and fits into the corresponding slot 6. Thus, the micro switch 2 is further fixed through the cooperation between the hook 9 and the slot 6 to prevent displacement and deflection. When the micro switch 2 is fixed... When the microswitch 2 is mounted on the insulating bracket 1, the boss 7 can fit against the bottom of the microswitch 2 to act as a limit, thereby preventing the microswitch 2 from moving downwards and ensuring its fixation in three directions. After the microswitch 2 is fixed on the insulating bracket 1, a pair of first springs 3 and a pair of second springs 4 can return to their original state and fit against both sides of the microswitch 2 to clamp it, thus preventing it from wobbling left and right. After the microswitch 2 is fixed, the cover is closed. The cover will compress the contact springs on the microswitch 2, and the insulating bracket 1 will hold the microswitch 2 in place, preventing it from wobbling left and right. After the contact springs are compressed to a certain size, the microswitch 2 will conduct internally, and the signal will be transmitted through the signal line. Compared with existing fixing schemes, the microswitch 2 fixing method in this application can greatly reduce the number of parts, thereby reducing costs and effectively reducing weight, while also increasing assembly efficiency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
