Description

Reversing light switch

Technical field

The utility model relates to field of automobile parts and components, in particular to a kind of reversing light switch.

Background technique

Presently used reversing light switch uses mechanical contact-type structure or reed-type structure, belongs to open type switch.It is this There are following defects for the mechanical switch of type: 1, internal without oil sealing, oil, which penetrates into, causes switch jaw contact face to have oil film, easily causes and connects Touch it is bad, it is bright when disconnected when back-up lamp.2, reed is mechanical force deformation structure, after being used for a long time under high temperature, because Fatigue Deformation power becomes Difference, easily causes poor contact, and when back-up lamp is bright when disconnected.3, contact process is easy arcing electric discharge, and moment generates high temperature, burns contact Erosion, back-up lamp do not work.

Because needing a kind of novel reversing light switch to avoid disadvantages described above.

Utility model content

In view of this, the purpose of this utility model is that poor contact and ablation cannot be eliminated at all for contact switch Problem proposes a kind of using novel touch switching technique scheme.

Reversing light switch provided by the utility model, including socket, pedestal, push rod, reset spring, permanent magnet and dry spring Pipe；The socket is fixed on pedestal upper end, is equipped with switching circuit in socket, the tongue tube is set to the switching circuit and is used for Control its on-off；The push rod is snug fit at pedestal, and pedestal is stretched out in lower end, and the upper end is fixed for and the tongue tube sense The permanent magnet answered；The reset spring is located in pedestal for pushing push rod to reset.

Further, it is fixed with sealing cover close to upper end in the pedestal, sealing cover is equipped with the blind hole for protruding into permanent magnet.

Further, the outer wall of the push rod is integrally formed with bulge loop, the reset spring bullet peak at sealing cover and bulge loop it Between.

Further, the pedestal includes integrally formed mounting base and sliding sleeve；The sealing cover is fixedly installed in the peace It fills in seat, the push rod is snug fit in the sliding sleeve.

Further, the outer wall of the sliding sleeve is equipped with external screw thread.

Further, the bottom end of the socket is equipped with bell and spigot, and is plugged in mounting base by the bell and spigot.

Further, sealing ring is equipped between the sealing cover and mounting base bottom.

Further, the bottom end of the push rod is hemisphere face.

The utility model has the beneficial effects that

The reversing light switch of the utility model, when push rod overcomes reset spring to move up, the permanent magnet on push rod will It is mobile close to tongue tube, so that reed switch conduction, connects the switching circuit in socket, when external driving force disappears Afterwards, push rod is completed to reset under the driving of reset spring, and switching circuit disconnects, this switching circuit has the advantage that 1. contacts Point closing, no arc discharge ablation and wear phenomenon；2, distance of reaction is short, and demand magnetic field is weak；3, low-power consumption, long-life.

Detailed description of the invention

The utility model is further described with reference to the accompanying drawings and examples:

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the cross-sectional view of the utility model；

Fig. 3 is the circuit connection diagram of the utility model.

Specific embodiment

As shown, the reversing light switch of the present embodiment, including socket 1, pedestal 5, push rod 6, reset spring 4, permanent magnet 7 With tongue tube 2；The socket 1 is fixed on 5 upper end of pedestal, and switching circuit is equipped in socket 1, and the tongue tube 2 is set to described Switching circuit is for controlling its on-off；The push rod 6 is snug fit at pedestal 5, and pedestal 5 is stretched out in lower end, and the upper end is fixed to be used In the permanent magnet incuded with the tongue tube 2；The reset spring 4, which is located at, is used to that push rod 6 be pushed to reset in pedestal 5, when When push rod 6 overcomes reset spring 4 to move up, the permanent magnet 7 on push rod 6 will be close to the movement of tongue tube 2, so that tongue tube 2 is led It is logical, connect the switching circuit in socket 1, the connection type of switching circuit is as shown in figure 3, two switch contacts 9 are solid It is scheduled in socket 1, after external driving force disappears, push rod 6 is completed to reset under the driving of reset spring 4, and switching circuit is disconnected It opens, this switching circuit has the advantage that 1. contact points 9 are closed, no arc discharge ablation and wear phenomenon；2, distance of reaction Short, demand magnetic field is weak；3, low-power consumption, long-life.

In the present embodiment, it is fixed with sealing cover 3 close to upper end in the pedestal 5, sealing cover 3, which is equipped with, protrudes into permanent magnet 7 Blind hole, the sealing cover 3 can be used the sealing materials such as rubber production, avoid greasy dirt from penetrating into the switching circuit in socket 1.

In the present embodiment, the outer wall of the push rod 6 integrally formed with bulge loop, 4 bullet of reset spring peak at sealing cover 3 with Between bulge loop.

In the present embodiment, the pedestal 5 includes integrally formed mounting base and sliding sleeve；The sealing cover 3 is fixedly installed in In the mounting base, the push rod 6 is snug fit in the sliding sleeve, the outer wall and the shape phase of hex-head nut of mounting base Together, facilitate and this switch is installed using tools such as spanners.

In the present embodiment, the outer wall of the sliding sleeve is equipped with external screw thread, and a settable threaded hole and external screw thread cooperation are realized The installation of this switch.
