Abstract
The present invention relates to a reversing light switch device which belongs to the engineering field of car electric appliances. The reversing light switch device comprises a push rod assembly, a bush, a casing, a spring, a rubber sealing gasket, a silver contact piece and a base pin seat assembly, wherein the push rod assembly is arranged on one end of the casing; the middle part in the casing is provided with the rubber sealing gasket, the middle part of the which is provided with a small boss; the circular silver contact piece and one end of the spring are sheathed on the boss, and the other end of the spring is inserted into a groove of the base pin seat assembly; meantime, the base pin seat assembly is provided with two copper base pins; the silver contact piece and the copper base pins respectively used as two electrodes of the switch. The design of the reversing light switch device overcomes the problem that the middle of the seal gasket of the imported reversing light switch is easy to buckle, and the spring is easy to deflect, which results in the reversing light to light all the time or not to light. The present invention enhances the service life and the reliability of the reversing light switch for a car and effectively avoids the early failure of the reversing light switch so as to make the reversing light switch have no fault completely when the car runs within 150, 000 kilometers.
Description
Technical field
What the present invention relates to is a kind of switching device, particularly a kind of Reverse lamp switch.Belong to car electrics engineering field.
Background technology
Reversing lamp is one of of paramount importance safety member in the vehicle complete vehicle, and the quality of its quality directly has influence on the serviceability of car load.And Reverse lamp switch is the safety component in the automotive transmission.In the past, the repair rate of the Reverse lamp switch of external and domestic automobile higher defectives such as (occur normal bright or) not working, it is quite serious that the user complains, just because of this slight switch, seriously has influence on the credit worthiness of user to the automobile brand quality.For preventing the generation again and again of this phenomenon, eliminate hidden danger, must take relative counter measures.By retrieval, Chinese patent title: Reverse lamp switch, the patent No.: ZL 95211990.0.This patent has increased sealing rubber cover in common Reverse lamp switch, cause the defective more than the misoperation to prevent machine oil infiltration.But the power that is subjected to is decomposed, very easily cause breakage, so cause sealing property to descend, reliability reduces greatly.Sealing rubber cover is an acrylonitrile-butadiene rubber simultaneously, and is very easily aging under high temperature and low temperature.
Summary of the invention
The invention reside in the deficiency that solves in the existing design, a kind of Reverse lamp switch is provided, make its problem that solves the normal bright of the frequent appearance of reversing lamp effectively or do not work, increase the service life, structurally also more simple, reliable.
The present invention is achieved by the following technical solutions, the present invention includes: push rod assembly, lining, housing, spring, rubber gasket, silver-colored contact and pin base assembly.Its annexation is: lining is press-fit in the housing end face, the push rod assembly is arranged in the lining, middle part in housing is provided with one " bowl-type " rubber gasket, one little boss is arranged at the middle part of this rubber gasket, a circular silver-colored contact and an end of spring are enclosed within on this boss, and the other end of spring is inserted in the groove on the pin base assembly, and two copper pins are arranged on the pin base assembly simultaneously, and silver-colored contact and copper pin are respectively as two electrodes of switch.
Wherein, gasket seal is the high-strength material rubber part, guarantee switch can be in-40 ℃～140 ℃ scope operate as normal, and be designed to " bowl-type " structure by the common planar structure, promptly in the middle of planar structure, design a small boss, be used for suit silver contact and spring on it, to prevent seal distortion and spring deflection, guarantee the accurate, reliable of switch on and off stroke, and the limit of gasket seal is the fold typing, the thrust that can decompose suffered declutch shift shaft, the resistance to pressure of increase gasket seal increases the service life.
The pin Front-end Design makes V-arrangement into by original plane, promptly is equivalent to two contacts, and when a contact is damaged, still can work in another contact, has increased the reliability of contact like this.
The thickness of silver contact is 0.8mm, and it is indeformable to protect positive switch connection, and increases a ￠ 3mm endoporus at the center, as positioning reference, guarantees that silver-colored contact when work, moves all the time on axial line, to improve the reliability of switch.The diameter of little spring outer ring is ￠ 6, has increased the rigidity of little spring, to improve stability, reaches the possibility of getting rid of Chang Liang.Guaranteeing that the switch connection scope is on the basis of 14.8～15.8mm, the connection stroke of strict control switch, the connection stroke is 1.0～1.4mm.
The present invention is through above improvement and design, decomposed the suffered power of rubber gasket, the life-span and the reliability of vehicle switch have been improved significantly, before use 168/thousand of thousand failure rates are reduced to 1.8/thousand after the use, avoided early failure, guaranteed that effectively Reverse lamp switch defective in 150,000 kilometers of running cars is zero target.

Embodiment
As shown in Figure 1, the present invention includes: push rod assembly 1, lining 2, housing 3, rubber gasket 4, silver-colored contact 5, little spring 6, pin base assembly 7.Its annexation is: lining 2 press fit over the end face of housing 3, push rod assembly 1 is arranged on an end of lining 2, middle part in housing 3 is provided with a rubber gasket 4, at the middle part of this rubber gasket 4 small boss is arranged, a circular silver-colored contact 5 and an end of little spring 6 are enclosed within on this boss, and the other end of little spring 6 is inserted in the groove on the pin base assembly 7, and two copper pins are arranged on pin base assembly 7 simultaneously, and silver-colored contact and copper pin are respectively as two electrodes of switch.
The thickness of silver contact is 0.8mm, and the endoporus that increases ￠ 3. at the center is as positioning reference.The diameter of silver contact and spring outer ring is ￠ 6mm.The connection stroke of Reverse lamp switch is 1.0～1.4mm.The front end of two copper pins on the pin base assembly 7 is the V-arrangement pin of two contacts.
When pressing lower push rod assembly 1, promote rubber gasket 4 and on it silver-colored contact 5 of suit move along thrust direction together, press to pin base assembly 7.When pin on the pin base assembly 7 contacts, constituted a loop, at this moment, switch is on-state, circuit turn-on, reversing lamp is shinny.When unclamping push rod assembly 1, under the effect of little spring 6 tension force, diaphragm seal 4 and its silver-colored contact 5 of going up suit reset jointly, the circuit disconnection, and reversing lamp extinguishes.
