Abstract
The utility model provides a neutral/reverse gear signal lamp switch which is characterized by comprising a casing, a switch box, a pull rod, a steel ball and an insert piece, wherein the switch box, the pull rod, the steel ball and the insert piece are arranged in the casing. The pull rod and the insert piece are installed in the switch box, the steel ball drives the pull rod to move, a pull rod spring is arranged between the steel ball and the pull rod, and a plane sealing pad is arranged on the end face of the switch box contacted with the casing along the radial direction. The whole neutral/reverse gear signal lamp switch is divided into two parts, namely the casing, a push part and the switch box part, and plane sealing and connection of the two parts are achieved by arranging the plane sealing pad. Due to the fact that the plane sealing pad is extremely reliable in sealing performance, the problem of sealing oil leakage caused to the neutral/reverse gear signal lamp switch for a long term is fundamentally solved.

Further, said planar sealing pad is a silicone rubber plate.
Further, said switch enclosure comprises a switch enclosure cover and a switch cassette holder, and switch enclosure cover and switch cassette holder are connected together, and inner formation one is used to place the cavity of push rod and inserted sheet; Said switch enclosure cover is provided with first axis hole that is used for localization handspike, and said switch cassette holder is provided with second axis hole that is used for localization handspike.
Further, an end of said push rod is installed in first axis hole, and the other end is installed in second axis hole.
Further, said push rod is provided with a break-over disk, and break-over disk and push rod are structure as a whole; Said break-over disk along the circumferential direction is provided with two through holes, is separately installed with a round end contact in two through holes.
Further, be provided with a movable contact spring spring in the said switch cassette holder, said movable contact spring spring is through the location of the annular recess on the switch cassette holder.
The described neutral gear of the utility model
/The signal lamp switch that reverses gear is divided into two partly with switch integral body; Be shell and promotion part and switch enclosure part; Between two parts through a planar sealing pad is set; Realized flat seal and be connected,, therefore thoroughly solved the sealing leakage of oil problem of long-term puzzlement neutral gear/reverse gear signal lamp switch because the sealing of flat seal is very reliable.
The utility model is designed to two parts of split with switch enclosure, and on switch cassette holder and switch enclosure cover, distinguishes axle holes, is used for the location of push rod; Realize accurate, the stable location of push rod, the impulse stroke of switch is reliably guaranteed, the disposable qualification rate of product has been brought up to more than 99.8%, be neutral gear
/The full-automation production of signal lamp switch of reversing gear provides good basis.
The utility model has also been realized the accurate location to break-over disk because push rod is carried out the pinpoint while, has eliminated the hidden danger that break-over disk is stuck easily successively, has reduced the probability of switch failure, for traffic safety provides favourable guarantee.
