Abstract
The utility model discloses an automobile normally closed contact type reversing light switch assembly, which comprises a steel ball (1), an ejector rod component, a casing (2), a contact chip component (9) and a base component (11). Insulation sealing gaskets (7) are arranged among an ejector head (5) of the ejector rod component, the casing (2) and the contact chip component (9), small springs (6) are arranged among the ejector head (5) and the insulation sealing gaskets (7), a base spring (10) is arranged between the contact chip component (9) and a base component (11), the contact chip component (9) and an electrode plate (12) of the base component (11) are in a normally closed state, and the contact chip component (9) and the electrode plate (12) of the base component (11) are both provided with at least two pairs of contacts. Even if one of the contacts on the contact chip component or the electrode plate of the base component is worn over and is in poor contact, the other contacts can be in contact operation normally. The automobile normally closed contact type reversing light switch assembly has the advantages of multi-point contact, fine electrification and long service life.
Description
One, technical field
The utility model relates to the normally-closed contact formula Reverse lamp switch assembly of using on a kind of automobile.
Two, background technology
At present, the Reverse lamp switch assembly of using on the automobile generally is divided into open type (two contacts are in open mode at ordinary times) and closed type (two contacts are in closure state at ordinary times).Wherein, automobile can only rely on only separately pair of contact with contacting between the contact on the contact chip of normally-closed contact formula Reverse lamp switch assembly and the base electrode sheet.If one of them contact wear is excessive or loose contact, also can't make the normal use of switch and make switch failure even then cause two contacts to contact, shortened its useful life.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, is the automobile of multiple spot contact normally-closed contact formula Reverse lamp switch assembly between a kind of contact and provide.
The purpose of this utility model realizes by following technical solution: a kind of automobile normally-closed contact formula Reverse lamp switch assembly, comprise push rod component, housing, contact chip assembly and base assembly, the top of push rod component, be provided with the insulated enclosure packing ring between housing and the contact chip assembly, be provided with little spring between top and the insulated enclosure packing ring, be provided with the base spring between contact chip assembly and the base assembly, be normally off between the electrode slice of contact chip assembly and base assembly, the contact on the electrode slice of described contact chip assembly and base assembly is a plurality of contacts of at least two pairs.
After adopting the utility model structure, excessive wear, loose contact appear in a contact even the contact on the electrode slice of contact chip assembly or base assembly has wherein, but other contacts can normally contact work in the same old way.Therefore, the utility model compared with prior art has that multiple spot contact, energising are good, the advantage of long service life.
Four, description of drawings
Below in conjunction with accompanying drawing and execution mode the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model automobile with normally-closed contact formula Reverse lamp switch assembly.
Fig. 2 is the vertical view of the contact chip assembly (its contact is two pairs) among Fig. 1.
Fig. 3 is the vertical view of the base assembly (its electrode slice contact is two pairs) among Fig. 1.
Fig. 4 is the vertical view of the contact chip assembly (its contact is four pairs) of another embodiment of the utility model.
Fig. 5 is the vertical view of the base assembly (its electrode slice contact is four pairs) of another embodiment of the utility model.
Five, embodiment
Referring to figs. 1 through Fig. 3 as can be known, the utility model automobile normally-closed contact formula Reverse lamp switch assembly, comprise steel ball 1, push rod component, housing 2, contact chip assembly 9 and base assembly 11, the top 5 of push rod component, between housing 2 and the contact chip assembly 9 (promptly come directly towards 5 and contact chip assembly 9 between, and between housing 2 and the contact chip assembly 9) be provided with insulated enclosure packing ring 7 (for known technology), be provided with little spring 6 between top 5 and the insulated enclosure packing ring 7, be provided with base spring 10 between contact chip assembly 9 and the base assembly 11, be normally off between the electrode slice 12 of contact chip assembly 9 and base assembly 11, the contact on the electrode slice 12 of described contact chip assembly 9 and base assembly 11 is a plurality of contacts of at least two pairs.(Fig. 2, Fig. 3 show be two pairs, what Fig. 4, Fig. 5 showed is four pairs, also can be three pairs, or the like).
Wherein, push rod component is made of push rod 3, push rod spring 4, top 5 etc., the elastic force of set little spring 6 is less between top 5 and the insulated enclosure packing ring 7, the contact between the electrode slice on contact chip assembly and the base assembly is not separated (promptly still being normally off), when steel ball, when push rod is stressed, the contact between the electrode slice on contact chip assembly and the base assembly separated to have a regular hour poor.At the inner side edge of described housing 2 and between insulated enclosure packing ring 7 and base assembly 11, be provided with positioning adapter 8, contact dislocation with contact between the electrode slice effectively to prevent the contact chip assembly.
Be normally off between the electrode slice 12 of contact chip assembly 9 of the present utility model and base assembly 11, when promptly steel ball, push rod are not worked, the corresponding contact in a plurality of contacts between the electrode slice 12 of contact chip assembly 9 and base assembly 11, switch is in "on" position.At this moment, excessive wear, loose contact appear in a contact even have wherein, but other contact can normally contact work in the same old way, makes switch be in "on" position.During as steel ball, the stressed work of push rod, make contact chip assembly 9 break away from the electrode slice 12 of base assembly 11, contact chip assembly and electrode slice are separated, then switch is in off-position.
Claims (2)
1. an automobile is with normally-closed contact formula Reverse lamp switch assembly, comprise steel ball (1), push rod component, housing (2), contact chip assembly (9) and base assembly (11), the top of push rod component (5), be provided with insulated enclosure packing ring (7) between housing (2) and the contact chip assembly (9), be provided with little spring (6) between top (5) and the insulated enclosure packing ring (7), be provided with base spring (10) between contact chip assembly (9) and the base assembly (11), between the electrode slice (12) of contact chip assembly (9) and base assembly (11) is normally off, it is characterized in that: the contact on the electrode slice (12) of described contact chip assembly (9) and base assembly (11) is a plurality of contacts of at least two pairs.
2. automobile as claimed in claim 1 is characterized in that with normally-closed contact formula Reverse lamp switch assembly: at the inner side edge of described housing (2) and be provided with positioning adapter (8) between insulated enclosure packing ring (7) and base assembly (11).
