Abstract
The utility model discloses an ignition switch. The ignition switch has low operating current under an operating state, a contact uneasy to ablate, and a long service life, and overcomes defects of large operating current which easily results in an ablated contact, bad contact, a reduced service life, and product failure in advance of the ignition switch in the prior art. The automobile ignition switch comprises a housing and a pedestal. A rotating core block is disposed in the housing and is rotatably connected with the housing. An elastic mechanism is disposed on the rotating core block and has conductive rubber disposed on the tail end of the elastic mechanism, wherein the conductive rubber is connected with the elastic mechanism. A pedestal chip is disposed on the pedestal and is equipped with a movable contact sheet provided with bumps. The bumps contact the pedestal. The ignition switch is suitable for occasions where an ignition switch is suitable previously and has advantages of low operating current, an uneasily-ablated contact, and a long service life.
Description
Technical field
The utility model belongs to car electrics accessory field, relates in particular to a kind of ignition switch.
Background technology
Ignition switch is the critical component of automobile starting part, the driver by ignition switch control automobile startup, close.Ignition switch of the prior art is all generally large current work, namely in working order under operating current through the contact larger, this easily causes pitting of contact, loose contact, the life-span reduces, and product was lost efficacy in advance.
China Patent Publication No. CN201904230U, open day on July 20th, 2011, the name of utility model is called ignition switch, this application case discloses a kind of ignition switch, its static contact is laminated structure, at least be provided with a riveted holes on static contact, terminal block is provided with the through hole corresponding with described riveted holes, passes through the closing-up of semi-hollow between static contact and terminal block together.Have simple in structure, save raw material, easily riveted joint and the low characteristics of cost.This utility model weak point is, remains conventional large current work, easily causes pitting of contact, loose contact, and the life-span reduces, and product was lost efficacy in advance.
The utility model content
The ignition switch operating current that the utility model has overcome prior art is larger, easily causes pitting of contact, loose contact, life-span reduces, and the deficiency that product was lost efficacy in advance provides the operating current under a kind of operating state less, the contact is difficult for ablation, the ignition switch of long service life.
The utility model is achieved through the following technical solutions:
A kind of ignition switch, comprise shell, base, be provided with the rotation pellet in described shell, described rotation pellet and shell are rotationally connected, described rotation pellet is provided with elastic mechanism, and described elastic mechanism latter end is provided with the conductive rubber that is attached thereto, and described base is provided with the base chip, also be provided with the movable contact spring with salient point on described rotation pellet, described salient point contacts with base.Salient point on movable contact spring is exactly the conducting contact, rotates pellet and rotates together for rotating and drive movable contact spring, and movable contact spring rotates on the surface of base chip, thereby realizes conducting and the break function of base chip; Elastic mechanism is used for moving up and down and drive conductive rubber and moves together, thereby realizes conducting and the break function of conductive rubber and base chip.These two circuits can be used for two kinds of gears or two kinds of different external connection electric devices, and in use, the operating current of two circuits separates, the one tunnel through conductive rubber, another road through movable contact spring, so electric current can be not excessive, the contact is difficult for ablation, working life is longer.
As preferably, described elastic mechanism comprises spring stand, and described spring stand is provided with spring pedestal, is provided with spring in described spring stand.Spring stand can move up and down, and drive conductive rubber and press down or rise, thus conducting and the disconnection of control conductive rubber and base chip.
As preferably, described movable contact spring is provided with two trepannings, and described rotation pellet is provided with two protruded stigmas corresponding with trepanning, and the engage sleeves of described movable contact spring by trepanning and protruded stigma is located at rotates on pellet.When rotating the pellet rotation, can drive movable contact spring and rotate together, the contact position that is used in conducting changes, thereby realizes on-off function.
As preferably, described base chip and base are integrated injection mo(u)lding.Make that the base chip is firm to be fixed on base, the structural stability when improving ignition switch and using.
As preferably, described salient point number is four, and the line of described salient point point-blank.When utilizing movable contact spring to rotate, on it, relative variation of salient point and base chip position realizes conducting, the disconnection of base chip place circuit.
Therefore, the beneficial effects of the utility model are: (1) contact is difficult for ablation, and job stability is high, long service life; (2) can be used for controlling simultaneously the break-make of two gears or two different external connection electrical apparatus spares.
Description of drawings

Fig. 2 is the structural representation of the utility model movable contact spring.
In figure: shell 1, base 2, rotation pellet 3, conductive rubber 4, base chip 5, movable contact spring 6, salient point 7, spring stand 8, spring pedestal 9, spring 10, trepanning 11.
Embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of ignition switch as shown in Figure 1 and Figure 2, comprise shell 1, base 2, be provided with in described shell 1 and rotate pellet 3, described rotation pellet 3 is rotationally connected with shell 1, described rotation pellet 3 is provided with elastic mechanism, and described elastic mechanism latter end is provided with the conductive rubber 4 that is attached thereto, and described base 2 is provided with base chip 5, also be provided with the movable contact spring 6 with salient point 7 on described rotation pellet 3, described salient point 7 contacts with base 2.Salient point 7 on movable contact spring 6 is exactly the conducting contact.Described elastic mechanism comprises spring stand 8, and described spring stand 8 is provided with spring pedestal 9, is provided with spring 10 in described spring stand 8.Spring stand 8 can move up and down, and drive conductive rubber 4 and press down or rise, thus conducting and the disconnection of control conductive rubber 4 and base chip 5.Described movable contact spring 6 is provided with two trepannings 11, and described rotation pellet 3 is provided with two protruded stigmas corresponding with trepanning 11, and described movable contact spring 6 is located on rotation pellet 3 by the engage sleeves of trepanning 11 and protruded stigma.When rotating pellet 3 rotation, can drive movable contact spring 6 and rotate together, the contact position that is used in conducting changes, thereby realizes on-off function.Described base chip 5 is integrated injection mo(u)lding with base 2.Make that base chip 5 is firm to be fixed on base 2, the structural stability when improving ignition switch and using.Described salient point 7 numbers are four, and the line of described salient point 7 point-blank.When utilizing movable contact spring 6 to rotate, on it, relative variation of salient point 7 and base chip 5 positions realizes conducting, the disconnection of base chip 5 place circuits.
The utility model is rational in infrastructure, the operating current of the different operating element different circuit of flowing through, and the operating current that the significant points such as contact are passed through in use is less, is difficult for ablation, and useful life is longer.
