Abstract
The utility model discloses an automobile normally open type plastic reversing light switch assembly, which comprises an ejector rod component, a casing (2), a contact chip component (7) and a base component (9). Sealing gaskets (6) are arranged among an ejector head (5) of the ejector rod component, the casing (2) and the contact chip component (7), a base spring (8) is disposed between the contact chip component (7) and the base component (9), the contact chip component (7) and an electrode plate (10) of the base component (9) are in a normally open state, and the contact component (7) and the electrode plate (10) of the base component (9) are both provided with at least two pairs of contacts. The base component (9) is a plastic base component disposed obliquely. 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 open type plastic 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 opened contact formula Reverse lamp switch assembly that a kind of automobile is used.
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 opened 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 opened contact formula plastics 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 opened contact formula plastics Reverse lamp switch assembly, comprise push rod component, housing, contact chip assembly and base assembly, be provided with seal washer between the top of push rod component, housing and the contact chip assembly, be provided with the base spring between contact chip assembly and the base assembly, be normally open 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 opened contact formula plastics 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 three pairs) of another embodiment of the utility model.
Fig. 5 is the vertical view of the base assembly (its electrode slice contact is three 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 opened contact formula plastics Reverse lamp switch assembly, comprise that push rod component is (by push rod 3, push rod spring 4, come directly towards 5 compositions such as grade), housing 2, contact chip assembly 7 and base assembly 9, the top 5 of push rod component, between housing 2 and the contact chip assembly 7 (promptly come directly towards 5 and contact chip assembly 7 between, and between housing 2 and the contact chip assembly 7) be provided with seal washer 6 (for known technology), be provided with base spring 8 between contact chip assembly 7 and the base assembly 9, be normally open between the electrode slice 10 of contact chip assembly 7 and base assembly 9, contact on the electrode slice 10 of described contact chip assembly 7 and base assembly 9 is a plurality of contact (Fig. 2 of at least two couples, what Fig. 3 showed is two pairs, Fig. 4, what Fig. 5 showed is three pairs, also can be four pairs, or the like).
Wherein, housing 2 outer " O " type circles 1 that also are with; Be provided with push rod spring 4 in the push rod 3, the inner end of push rod 3 is equipped with the top 5 that links to each other with push rod spring 4; Described base assembly 9 is the shaped plastics base assembly of oblique setting; The setting of seal washer has been stopped housing poorly sealed reality when being riveted in the base assembly and has been caused the poor sealing problem.Be provided with locating piece 11 on described base assembly 9 and at contact chip assembly 7 places, base assembly 9 also can be made overall structure with locating piece 11, contacts dislocation effectively to prevent the contact chip assembly with contact between the electrode slice.
Be normally open between the electrode slice 10 of contact chip assembly 7 of the present utility model and base assembly 9, when promptly push rod was not worked, contact chip assembly 7 broke away from the electrode slice 10 of base assembly 9, and the contact chip assembly separates with electrode slice, and switch is in off-position.During as the stressed work of push rod, push contact chip assembly 7 electrode slice 10 of base assembly 9 to by top 5, make the corresponding contact in a plurality of contacts between the electrode slice 10 of contact chip assembly 7 and base assembly 9, 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.
Claims (3)
1. an automobile is with normally opened contact formula plastics Reverse lamp switch assembly, comprise push rod component, housing (2), contact chip assembly (7) and base assembly (9), the top of push rod component (5), be provided with seal washer (6) between housing (2) and the contact chip assembly (7), be provided with base spring (8) between contact chip assembly (7) and the base assembly (9), between the electrode slice (10) of contact chip assembly (7) and base assembly (9) is normally open, it is characterized in that: the contact on the electrode slice (10) of described contact chip assembly (7) and base assembly (9) is a plurality of contacts of at least two pairs.
