Description

Technical Field

[0001] This application relates to the field of battery power-off switch technology, and in particular to a novel power-off switch. Background Technology

[0002] Electronic devices in a vehicle connect to the battery via a power-off switch to be powered by the battery. Some existing battery power-off switches use springs to connect or disconnect conductive plates from the terminals and clips, thus enabling or disabling power. However, over time, the spring's elasticity weakens, causing the conductive plates to lose contact with the terminals and clips under spring force, preventing power from being supplied to the devices. Utility Model Content

[0003] In order to effectively solve the problem that power-off switches using springs cannot be used continuously due to the weakening of spring force, this application provides a new type of power-off switch.

[0004] The novel power-off switch provided in this application adopts the following technical solution:

[0005] A novel power-off switch includes a housing, a receiving cavity, a conductive sheet, a post, and a conductive clip. The switch further includes a bolt and a limiting groove. The bolt shank is threadedly connected to the conductive sheet within the receiving cavity. The outer wall of the conductive sheet is slidably connected to the inner wall of the limiting groove. The post and the conductive clip are respectively disposed on both sides of the bolt and extend at least partially into the limiting groove.

[0006] To further improve the implementation of this application, the following structure is specifically adopted: both the column head and the conductive clip are located at the bottom end of the limiting groove.

[0007] To further improve the implementation of this application, the following structure is specifically adopted: both the column head and the conductive clip are located at the top of the limiting groove.

[0008] To further improve the implementation of this application, the following structure is specifically adopted: it also includes an elastic member, one end of which abuts against the inner side of the top surface of the housing, and the other end of which abuts against the conductive sheet.

[0009] To further improve the implementation of this application, the following structure is specifically adopted: it also includes an elastic member, one end of which abuts against the inner side of the bottom surface of the housing, and the other end of which abuts against the conductive sheet.

[0010] To further improve the implementation of this application, the following structure is specifically adopted: it also includes a knob, which is installed in conjunction with the head of the bolt.

[0011] Furthermore, to better realize this application, the following configuration structure is specifically adopted: it also includes indicating instruments.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. By setting the bolt rod body to be threadedly connected to the conductive sheet and the conductive sheet to be slidably connected to the inner wall of the limiting groove, with the column head and conductive clip respectively set on both sides of the bolt and both extending at least partially into the limiting groove, the existing technology of using a spring to connect or disconnect the conductive sheet from the column head and conductive clip can be changed to using a threaded connection to connect or disconnect the conductive sheet from the column head and conductive clip, eliminating the drawback that the spring may weaken due to long-term use;

[0016] 2. By setting a spring, the spring force is transmitted to the bolt through the conductive sheet, providing a circumferential force and preventing the bolt from rotating on its own;

[0017] 3. By setting a plum blossom retaining ring, the bolt shank is always kept partially inside the receiving cavity. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Embodiment 1 of this application discloses a novel power-off switch. (Refer to...) Figure 1 , Figure 2The novel power-off switch includes a housing 11, a receiving cavity 12, a conductive sheet 13, a post 14, a conductive clip 15, a bolt 16, a limiting groove 17, an elastic component 18, a perforated spring 19, an indicating instrument 20, and a knob 21. The bolt 16 passes through the top surface of the housing 11 from top to bottom and enters the receiving cavity 12, where it is threadedly connected to the conductive sheet 13. The outer wall of the conductive sheet 13 fits against the inner wall of the limiting groove 17, and the conductive sheet 13 slides up and down along the inner wall of the limiting groove 17. The post 14 and the conductive clip 15 are respectively provided with... Both sides of the bolt 16 are located at the bottom of the limiting groove 17 and extend at least partially into the limiting groove 17. The elastic component 18 is a spring, which is sleeved on the bolt 16 rod between the inner side of the top surface of the housing 11 and the conductive sheet 13. One end of the spring abuts against the inner side of the top surface of the housing 11, and the other end abuts against the upper surface of the conductive sheet 13. The bottom surface of the knob 21 is fitted with the head of the bolt 16. The plum blossom retaining ring 19 is set on the bolt 16 rod located in the receiving cavity 12. The indicating instrument 20 is set in the groove on the surface of the housing 11.

[0023] Example 2: This example is basically the same as Example 1, except that the column head 14 and the conductive clip 15 are respectively set on both sides of the bolt 16 and are both located at the top of the limiting groove 17 and extend into the limiting groove 17 at least partially. The spring is sleeved on the bolt 16 rod between the bottom surface of the outer shell 11 and the conductive sheet 13. One end of the spring abuts against the bottom surface of the outer shell 11 and the other end abuts against the lower surface of the conductive sheet 13.

[0024] The implementation method of a novel power-off switch according to an embodiment of this application is as follows: (Refer to...) Figures 1-2 In use, the new type of power-off switch has its pin 14 fitted onto the battery electrode (the attached drawing only shows the part of the pin 14 that is connected and disconnected with the conductive sheet 13 in the accommodating cavity 12; the part of the pin 14 that can be fitted onto the battery electrode is not shown, and this part is exposed outside the outer shell 11). The new type of power-off switch has its conductive clip 15 fitted onto the electrical equipment that needs to be used (the attached drawing only shows the part of the conductive clip 15 that is connected and disconnected with the conductive sheet 13 in the accommodating cavity 12; the part of the conductive clip 15 that can be fitted onto the electrical equipment that needs to be used is not shown, and this part is exposed outside the outer shell 11). By rotating the bolt 16 with the knob 21, the bolt 16 is threadedly connected to the conductive sheet 13. The bolt 16 drives the conductive sheet 13 to move downward along the limiting groove 17 until the conductive sheet 13 is connected to the pin 14 and the conductive clip 15. At this time, the state is connected. Rotating knob 21 in the reverse direction causes bolt 16 to move conductive plate 13 upward along limiting groove 17, disengaging conductive plate 13 from post head 14 and conductive clip 15. The device is now in the disconnected state. Indicating instrument 20 can be used to measure the voltage and / or current of the device under test.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
