[0027] Embodiment

[0028] Reference Figures 1-5 , the HT24 power supply main switch assembly, includes an upper housing 3 and a lower housing 4. The upper housing 3 and the lower housing 4 are hermetically connected. An upper cover 2 is provided above the upper housing 3. A rotating member is provided at the top of the upper housing 3. A guide plate mandrel 13 is abutted against the bottom of the rotating member. The guide plate mandrel 13 is connected to a conductive plate assembly 14. The guide plate mandrel 13 can move up and down in the lower housing 4. The conductive plate assembly 14 includes a conductive plate 142 and a terminal 144. The conductive plate 142 and the terminal 144 can be in contact connection. Rotating the rotating member can change the contact state between the conductive plate 142 and the terminal 144.

[0029] There are two tubular rivets 17 symmetrically arranged between the upper shell 3 and the lower shell 4. Through the riveting of the tubular rivets 17, a nut 18 is inlaid inside the lower shell 4. The nut 18 is arranged at the bottom of the tubular rivet 17. A bolt 6 penetrates through the tubular rivet 17. The bolt 6 penetrates through the upper shell 3 and the lower shell 4, and the bolt 6 is rotationally connected with the nut 18 in a matching manner. The bolt 6 extends out of the lower shell 4 through the nut 18. A groove is formed on the lower shell 4, and a convex rib matching the groove is formed on the upper shell 3. A main body sealing ring 12 is arranged in the groove. The main body sealing ring 12 is made of rubber. The rotating part is a handle. An O-ring 11 is arranged at the rotating part of the handle and the upper shell 3. The handle is rotationally and sealingly connected with the upper shell 3 through the O-ring 11.

[0030] A upper compression spring 15 is connected to one side of the conductive plate 142. The other end of the upper compression spring 15 is connected to the guide plate core shaft 13. A pressure block 145 is connected to the other side of the conductive plate 142. The other end of the pressure block 145 presses against a lower compression spring 16. The lower compression spring 16 is arranged directly below the lower pressure block 145. Conductive blocks 143 are arranged below the positions of the conductive plate 142 near both ends. The conductive blocks 143 are connected with terminal posts 144. The terminal posts 144 are arranged in the sockets inside the lower shell 4. A protective cover 1 is rotatably arranged on the upper cover 2 body. The protective cover 1 is rotationally connected with the upper cover 2 body through a pin shaft 9 arranged thereon. A torsion spring 8 is arranged on the pin shaft 9. An anti-detachment groove 7 is arranged on the outer surface of the lower cover body near the bottom. The lower cover body is spirally and fixedly connected with the installation body through the anti-detachment groove 7. By spirally connecting through the anti-detachment groove 7, it can prevent the switch assembly from vibrating and detaching during use.

[0031] The rotation angle of the handle 5 of this switch assembly is 45°. By rotating and pressing the guide plate core shaft 13 with the handle 5, the guide plate core shaft 13 compresses the upper compression spring 15. The upper compression spring 15 acts on the conductive plate 142, causing both ends of the conductive plate 142 made of metal material to move downward and form a connection with the conductive blocks 143 and the terminal posts 144, so as to achieve the manual opening of a small current signal. For the rotatable protective cover 1, when the switch is in the OFF gear, the protective cover 1 cannot be buckled, and when it is in the ON gear, the protective cover 1 can be covered. There is a groove for installing the main body sealing ring 12 on the lower shell 4, and a convex rib matching this is arranged on the upper shell 3, so that the upper and lower shells 4 are tightly sealed and can reach the sealing level of IP67. Screws 10 are arranged between the upper shell and the lower shell to strengthen the fixation between the upper shell and the lower shell through the screws 10.

[0032] The main switch of this starting power supply is a device for controlling the on / off of small current signals. This power switch is a manual switch for small current signals that can be turned on by rotating at a small angle of 45 degrees. The main power switch is installed outside the driver's cab and is fixed by bolts. It is installed outside the driver's cab through a switch bracket. The two terminal posts adopt an injection molding structure integrally formed with the lower housing, and the terminal posts are injection molded into the lower housing in a predetermined quantity and distribution manner. Of course, in addition to the injection molding structure of the terminal posts disclosed in this embodiment, on the premise of ensuring the basic installation function, other existing replaceable structural forms can also be selected for the terminal posts.

[0033] Starting from the requirements of the whole vehicle, fully analyze the layout characteristics of the whole vehicle, thoroughly analyze the main power switch that is vulnerable to the influence of the vehicle signal power supply, make full use of the advantages and characteristics of various vehicle structures, and conduct a customized design for the structure of the main power switch. Adopt the side-fixed type to arrange it in a fixed position to achieve platformization. It can not only meet the needs of the modified vehicles of the whole vehicle, but also reduce the types of wiring harnesses and the comprehensive cost, and enhance the convenience of maintenance. Through visits to the market, convert customer requirements into design inputs. To achieve the convenience of taking power for modification, customize non-standard terminal posts and inject them into the lower housing, which can not only meet the customer's needs, but also not affect the appearance of the whole vehicle and will not damage the sealing performance of the main power switch.

[0034] During the production process of the main power switch, the hexagon thin nuts and bolts for after-installation are fixed on the outer side of the driver's cab. Because the positions of the power switch brackets of the models on the same platform are fixed, the main power switch realizes platformization and the position remains unchanged. Therefore, the modified vehicle will not cause wire harness changes due to the change of the position of the main power switch. And the maintenance is relatively convenient.

[0035] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
