Abstract
The utility model relates to an automobile ignition switch. The automobile ignition switch comprises a casing and a plastic head; a rotor is arranged in the casing; a key is matched with the rotor; an electricity conduction piece is arranged on one side of the rotor corresponding to the plastic head; a dynamic contact is fixedly connected with the electricity conduction piece; a static contact is arranged on the plastic head in the position corresponding to the dynamic contact and is connected with an insertion piece; a compression spring is sleeved on the other side of the rotor; and two ends of the compression spring are propped against the rotor and the casing. In the technical scheme provided by the utility model, since the compression spring always presses the rotor to the static contact, no clearance is generated between the dynamic contact and the static contact after long-term use of the automobile impulse generator, so that the service life of the automobile ignition switch is prolonged.
Description
Technical field
The utility model relates to the auto parts and components field, is specifically related to a kind of automobile ignition switch.
Background technology
Traditional automobile ignition switch generally includes housing and plastic cap, is provided with rotor in the housing; Be equipped with key with rotor, the first side of the corresponding plastics of movable contact headstock is provided with the sheet that conducts electricity, and sheet is fixedly connected with moving contact with conducting electricity; Be provided with fixed contact for the moving contact position on the plastic cap, fixed contact is connected with inserted sheet, this kind setting; Automobile ignition switch the gap occurs between moving contact and the fixed contact and can not conducting easily after long-term the use, thereby useful life is shorter.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of automobile ignition switch of longer service life.
For realizing above-mentioned purpose, the utility model provides following technical scheme: a kind of automobile ignition switch comprises housing and plastic cap; Be provided with rotor in the housing; Be equipped with key with rotor, the first side of the corresponding plastics of rotor is provided with the sheet that conducts electricity, and sheet is fixedly connected with moving contact with conducting electricity; Corresponding moving contact position is provided with fixed contact on the plastic cap; Fixed contact is connected with inserted sheet, and the relative fixed contact opposite side of said rotor is arranged with the compression spring, and said compression both ends of the spring compresses rotor and housing respectively.
Through adopting technique scheme,, guarantee that therefore automobile ignition switch the gap can not occur long-term the use between back moving contact and the fixed contact, thereby prolonged the useful life of automobile ignition switch because the compression spring is pressed rotor all the time to the fixed contact direction.
The utility model further is set to: the corresponding moving contact of said rotor position is provided with elastic component, and the two ends of said elastic component compress rotor respectively and conduct electricity sheet.
Through adopting technique scheme; Because the two ends of elastic component compress rotor respectively and conduct electricity sheet; Elastic component can be pressed to fixed contact with the sheet that conducts electricity; Because moving contact is fixedly connected with the sheet that conducts electricity, guarantees further that therefore automobile ignition switch the gap can not occur long-term the use between back moving contact and the fixed contact, thereby prolonged the useful life of automobile ignition switch.
The utility model further is set to: said elastic component is set to spring, and the corresponding moving contact of rotor position is provided with spring base, and spring is arranged in the spring base.
Through adopting technique scheme, spring is fixed in the spring base, and automobile ignition switch is not fragile in the long-term rear spring of using yet, and has further prolonged the useful life of automobile ignition switch.
The utility model further is set to: the first side of the corresponding plastics of said rotor also is provided with steel ball spring, is folded with steel ball between corresponding first end of plastics of steel ball spring and the plastic cap.
Through adopting technique scheme, because the effect of steel ball spring and steel ball makes automobile ignition switch be difficult for squinting at the long-term back rotor that uses, thereby further prolonged the useful life of automobile ignition switch again.
The utility model further is set to: said steel ball spring and steel ball all are set to two, and are symmetricly set on the rotor both sides with rotor center.
Through adopting technique scheme, make rotor rotation more steady.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model automobile ignition switch example structure figure.
Embodiment
Referring to accompanying drawing 1, the disclosed automobile ignition switch of the utility model comprises housing 1 and plastic cap 2; Be provided with rotor 3 in the housing 1, rotor 3 corresponding plastic cap 2 one sides are provided with the sheet 5 that conducts electricity, and sheet 5 is fixedly connected with moving contact 6 with conducting electricity; Be provided with fixed contact 7 for moving contact 6 positions on the plastic cap 2; Fixed contact 7 is connected with inserted sheet 8, and said rotor 3 relative fixed contact opposite sides are arranged with compression spring 4, and said compression spring 4 two ends compress rotor 3 and housing 1 respectively.Said rotor 3 corresponding moving contacts 6 positions are provided with elastic component 9, and the two ends of said elastic component 9 compress rotor 3 respectively and conduct electricity sheet 5.Through adopting technique scheme; Because compression spring 4 is pressed rotor 3 all the time to fixed contact 7 directions; Therefore guarantee that automobile ignition switch the gap can not occur long-term the use between back moving contact 6 and the fixed contact 7, thereby prolonged the useful life of automobile ignition switch.Because the two ends of elastic component 9 compress rotor 3 respectively and conduct electricity sheet 5; Elastic component 9 can be pressed to fixed contact 7 with the sheet 5 that conducts electricity; Because moving contact 6 is fixedly connected with the sheet 5 that conducts electricity; It is hereby ensured that automobile ignition switch the gap can not occur long-term the use between back moving contact 6 and the fixed contact 7, thereby prolonged the useful life of automobile ignition switch.
Present embodiment is preferably setting further: said elastic component 9 is set to spring, and rotor 3 corresponding moving contacts 6 positions are provided with spring base, and spring is arranged in the spring base.Through adopting technique scheme, spring is fixed in the spring base, and automobile ignition switch is not fragile in the long-term rear spring of using yet, and has further prolonged the useful life of automobile ignition switch.
Present embodiment further is set to: said rotor 3 corresponding plastic cap 2 one sides also are provided with steel ball spring 10, are folded with steel ball 11 between steel ball spring 10 corresponding plastic cap 2 one ends and the plastic cap 2.Through adopting technique scheme, because the effect of steel ball spring 10 and steel ball 11 makes automobile ignition switch be difficult for squinting at the long-term back rotor 3 that uses, thereby further prolonged the useful life of automobile ignition switch again.Present embodiment further preferably is set to: said steel ball spring 10 all is set to two with steel ball 11, and is symmetricly set on rotor 3 both sides with rotor 3 centers.So be provided with, it is more steady to make that rotor 3 rotates.
