Problems solved by technology
However, the original differential lock signal control switch device mostly adopts a complex structure through a micro switch, and the procurement cost is high, and the high temperature resistance of this micro switch is poor when the wire is welded, and the wire is easy to be twisted during installation. Due to the market share of auto parts companies in this field and the price competition advantages, the existing differential lock signal control switch must be developed in the aspects of simple structure, low manufacturing cost, and long service life.

Embodiment Construction
[0017] As shown in the figure, the differential lock signal control switch of the present invention includes a housing 1 and a gland assembly, a pressure head assembly and a conduction assembly arranged in the housing 1; the housing 1 is made of a metal material, Straight cylindrical shape, the center is a through hole, the first step, the second step and the third step are set in the hole, and the through hole is divided into the first step hole, the second step hole, the third step hole and the fourth step hole, from the top While down, the pore size decreases gradually. The lower end of the housing 1 is fixed on the brake axle 11 of the automobile by threads.
[0018] The gland assembly includes a gland 2, an adjusting screw 4, a lock nut 5 and a connecting piece 3, wherein the gland 2 is a stepped cylinder with a small diameter at the upper end and a large diameter at the lower end, and is closed by the rolling edge on the upper end of the housing 1. The gland 2 is fixed ...

The invention discloses a differential lock signal control switch which comprises a cylindrical shell body, a gland assembly, an indenter assembly and a breakover assembly, wherein the gland assembly, the indenter assembly and the breakover assembly are arranged in the shell body. The shell body is used as a negative electrode of a switch. A wiring inserting piece in the gland assembly is used as a positive electrode of the switch. The shell body and the wring inserting piece push a pressing cap to move towards an adjusting screw by pushing a push rod to drive a second compression spring to move together with the pressing cap in work. When the pressing cap contacts the adjusting screw, an current signal forms a closed loop circuit through the wiring inserting piece, the adjusting screw, the pressing cap, the second compression spring, the push rod, a first compression spring, the shell body and an automobile brake axle. A signal control switch is switched on. The differential lock signal control switch has the advantages of overcoming the defects that an existing differential lock signal control switch is complicated in structure, high in cost, unfirm in installation and use of wires, and being simple in structure, low in manufacturing cost, stable and reliable in work and the like.
Description
technical field [0001] The invention belongs to the technical field of automobile signal control devices, and relates to an automobile differential lock signal control switch. Background technique [0002] In recent years, with the rapid development of the automation of automobile electrical appliances, the structure and shape of signal control components for automobile axles have become more and more simple, and they are developing in the direction of lightweight. Various forms of electrical switches are widely used in vehicles. In the control system, especially in the differential lock control device of special vehicles. The differential lock signal control switch is an electrical switch that has been widely used in the special vehicle differential lock control system. It can realize the control output of the steering wheel differential lock signal when the car turns. However, the original differential lock signal control switch device mostly adopts a complex structure th...
