[0002] The electronic equipment in the vehicle is electrically connected to the battery through a wiring harness so that it can be powered by the battery. Usually, in situations such as vehicle maintenance or transportation, it is required to completely cut off the power, that is, it is required to completely cut off the electrical connection between the electronic equipment and the battery to avoid safety risks and to avoid the subsequent inability to start the vehicle due to power loss. The batteries of existing mass-produced vehicles usually do not have their own power-off switch devices, so it is necessary to install additional power-off switch devices to achieve power on and off between the battery and the wiring harness. However, for the existing rear-mounted power-off switch devices, most of them adopt a simple mechanical structure, which may have problems such as inconvenient operation, unstable contact, and insufficient safety. Due to its unstable structure in the power-off state, leakage may occur, so it is difficult to obtain a satisfactory completely power-off state. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] See also Figure 1-6 The utility model provides a technical solution for a square power-off switch:

[0021] Embodiment 1:

[0022] according to Figure 1 and Figure 2 As shown, a square power-off switch includes a switch box consisting of a knob seat 3, a shell 1 and a mounting seat 2. The knob seat 3 is arranged above the shell 1, and the mounting seat 2 is arranged inside the shell 1 and corresponds to the knob seat 3 up and down. A knob assembly 4 is mounted on the knob seat 3. A mounting groove 21 is opened at the bottom of the mounting seat 2, and clamping bolts 9 are installed around the mounting groove 21. The power-off switch can be installed on the battery terminal through the mounting groove 21 and the clamping bolts 9. An insulating gasket 91 can be arranged at the front end of the clamping bolt 9. The insulating gasket 91 improves the stability of the power-off switch installed on the battery. A negative pole clamp seat 7 is arranged on the shell 1. The structure of the negative pole clamp seat 7 is as shown in FIG. Figure 4 As shown, it includes a clamping column 71 fixed on the shell 1, and a wire clamping groove 72 is opened on the clamping column 71. The upper and lower ends of the negative wire clamp seat 7 are provided with clamping bolts 73. The negative wire of the power supply can be clamped and fixed in the wire clamping groove 72 of the negative wire clamp seat 7 by the clamping bolts 73.

[0023] from Figure 4 and Figure 6It can be seen that a special-shaped convex seat 31 is arranged at the top of the knob seat 3, and a supporting groove is arranged on the lower surface of the special-shaped convex seat 31 in a cross shape, and the horizontal groove part and the vertical groove part of the cross-shaped supporting groove have a height difference. A through groove is opened in the center of the knob seat 3, and the knob assembly 4 includes a rotating rod 42 which is vertically movable and sleeved in the through groove, and a latch 43 is fixedly sleeved laterally on the rotating rod 42, and the latch 43 can be snapped into the supporting groove of the special-shaped convex seat 31, and a knob 41 is fixedly sleeved on the upper end of the rotating rod 42. By screwing the knob 41, the latch 43 can be driven to rotate. With the cooperation of the special-shaped convex seat 31, the latch 43 is rotated from the low-position groove of the special-shaped convex seat 31 to the high-position groove, or from the high-position groove of the special-shaped convex seat 31 to the low-position groove.

[0024] A conductive sheet assembly 5 is provided in the housing 1, such as Figure 3 and Figure 4 As shown, the conductive sheet assembly 5 includes a movable conductive sheet 51 sleeved under the rotating rod 42, the movable conductive sheet 51 is connected to the mounting seat 2 through an elastic member 6, and fixed conductive sheets are arranged on the left and right sides of the movable conductive sheet 51, and the movable conductive sheet 51 and the fixed conductive sheet partially overlap, and the fixed conductive sheet includes a right conductive sheet 52 mounted on the mounting seat 2 and a left conductive sheet 53 fixed in the housing 1 through a negative electrode clamp seat 7, the right conductive sheet 52 is L-shaped, and mounting holes 81 are opened at the ends of the left conductive sheet 53 and the right conductive sheet 52, and the left conductive sheet 53 is mounted through the mounting hole 81 and the negative electrode clamp seat 7. Installed in the housing 1, the right conductive sheet 52 is fixed to the mounting base 2 by the mounting bolts 8. When the knob 41 causes the pin 43 to rotate in the groove with a height difference of the special-shaped protrusion, the movable conductive sheet 51 can be driven to move up and down. When the pin 43 is located in the low-position groove, the movable conductive sheet 51 moves up and contacts with the fixed conductive sheet, and the battery is energized. When the pin 43 is located in the high-position groove, the movable conductive sheet 51 moves down and away from the fixed conductive sheet, and the battery is de-energized. By rotating the knob 41 and coordinating the height difference between the pin 43 and the special-shaped protrusion, the movable conductive sheet 51 can be moved up and down, thereby realizing power on and off.

[0025] from Figure 5 It can be seen that a groove 22 is opened in the upper center of the mounting seat 2, and the elastic member 6 includes upper and lower insulating gaskets arranged below the movable conductive sheet 51 and in the groove 22 of the mounting seat 2, and the two insulating gaskets are connected by a spring 61. The spring 61 acts on the movable conductive sheet 51 to achieve the shaking of the movable conductive sheet 51 between the left and right conductive sheets, thereby ensuring the stability of the power supply between the movable conductive sheet 51 and the fixed conductive sheet. The upper and lower insulating gaskets can prevent the bottom mounting seat 2 and the movable conductive sheet 51 from being energized through the spring 61.

[0026] An indicating instrument 10, such as an ammeter and a voltmeter, is installed on the housing 1. The indicating instrument 10 is connected behind the power-off switch, and the other end of the indicating instrument 10 is connected to the positive electrode line of the battery. When power is on, the indicating instrument 10 can display the voltage and current of the battery. After power is off, the indicating instrument 10 returns to zero.

[0027] When used specifically, the utility model is a square power-off switch. When installing the power-off switch, the negative line of the battery is disconnected, and then the power-off switch is connected in series in the middle of the negative line. The negative line is inserted into the wire clamping groove 72 of the negative line clamp seat 7 and fixed by a clamping bolt 1 73. The power-off switch is directly installed on the battery through the bottom mounting groove 21 of the mounting seat 2 and fixed by a clamping bolt 2 9. The battery and the right conductive sheet 52 are energized through the mounting seat 2. Since the abutment groove of the special-shaped protrusion has a height difference, when the knob is rotated, the pin 43 can run from the low position of the special-shaped piece to the high position, driving the movable conductive sheet 51 to move down and separate from the fixed conductive sheet, and the battery is powered off. The knob is rotated in the opposite direction, and the pin 43 runs from the high position to the low position, driving the movable conductive sheet 51 to move up and contact with the fixed conductive sheet, the battery is powered off, and the conductive sheet assembly 5 is energized to achieve power on the battery.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
