Embodiment Construction

[0014] Examples such as Figures 1 to 5 As shown, a large current-resistant vehicle power-off switch includes a housing 1, a movable contact assembly 4 and a static contact assembly 6 arranged in the housing 1; The shaft assembly 2.

[0015] Specifically, the rotating shaft assembly 2 includes a rotating shaft 16, one end of the rotating shaft 16 protrudes from the housing 1, and a structure such as a rotating slot or a protruding piece is provided at the end, which can facilitate the rotation of the rotating shaft 16 with a key. Matching form. A second sealing ring 15 is arranged between the rotating shaft 16 and the housing 1 to ensure that dust and water will not enter the switch body from between the housing 1 and the rotating shaft 16 to ensure the stability and safety of the switch. The rotating shaft 16 is fixedly provided with a steel ball limiting plate 8 through the expansion riveting process, and a group of steel ball placement holes 7 are arranged on the steel ba...

Abstract

The invention discloses a high current resistance vehicle power off switch. The high current resistance vehicle power off switch comprises a casing body, a movable contact assembly and a static contact assembly, wherein the movable contact assembly and the static contact assembly are arranged in the casing body. The high current resistance vehicle power off switch further comprises a rotating shaft assembly which controls the movable contact assembly move up and down. The movable contact assembly comprises a copper plate and a pair of silver contact which is arranged on the copper plate. The static contact assembly comprises two wiring terminals. Each wiring terminal is provided on a silver contact. The diameter of each silver contact is between 9 and 10mm. The high current resistance vehicle power off switch provided by the invention has the advantages of high structural strength and great tightness, can meet harsh environment requirements, can withstand high current and high voltage, can meet the performance requirement of power on and off of a vehicle, and can be widely used in the field of the resistance vehicle power off switch.

Description

technical field [0001] The invention relates to the field of automobile switches, in particular to a large-current-resistant complete vehicle power-off switch. Background technique [0002] With the development of the automobile industry, the electrical performance requirements on vehicles are getting higher and higher. However, it is difficult to ensure that all circuits are in a power-off state when the existing vehicles are turned off, such as the lines around the battery in the front cabin, It is always in the energized state, usually the maximum instantaneous current of the vehicle can reach 175A, due to the large instantaneous current of the battery circuit, it is easy to cause harm to the human body during maintenance. For this reason, some power-off switches need to be added in places where some large currents pass, so as to reduce potential safety hazards. However, the existing automotive switch structure, due to its simple structure, cannot withstand instantaneous...
