Abstract
The utility model discloses a horn switch of a steering wheel of an automobile, which comprises a lower contact piece, an upper contact piece, a resetting spring and an installation bracket. The lower contact piece, the upper contact piece and the installation bracket are U-shaped, an elastic clip is installed on the installation bracket and sequentially penetrates through a lower contact piece and an upper contact piece, the lower contact piece is fixed on an installation groove arranged on the upper end face of the installation bracket, the resetting spring is arranged between the lower contact piece and the upper contact piece, and the upper contact piece is contacted with a clip head of the elastic clip in clamping mode under the effect of the resetting spring. The upper contact piece is provided with an upper copper column, the lower contact piece is provided with a lower copper column, and the upper copper column and the lower copper column are vertically right opposite to each other. The horn switch of the steering wheel is simple in structure and reliable in performance.
Description
Technical field
The utility model relates to the vehicle steering horn switch.
Background technology
The vehicle steering horn switch is used for the loudspeaker control on the steering wheel, unlatching through switch and the closed work that comes the Control of Automobile loudspeaker.
Existing vehicle steering horn switch generally is made up of contact piece, support, beam, insulation cushion and spring etc., the structure more complicated, and, be prone to phenomenons such as ablation because its contact piece contact area is little.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, the vehicle steering horn switch of dependable performance.
The said vehicle steering horn switch of the utility model; Comprise following contact chip, go up contact chip, return spring and installation bracket; Said following contact chip, last contact chip and installation bracket shape take the shape of the letter U, and on installation bracket, are provided with resilient clip, and resilient clip passes down contact chip and last contact chip successively; Following contact chip is fixed in the mounting groove of installation bracket upper surface setting; Return spring is arranged on down between contact chip and the last contact chip; Its upper end contacts with last contact chip; Its lower end is supported on the spring base bottom surface of installation bracket, and the bottom surface of spring base is higher than the upper surface of contact chip down, and last contact chip touches on the dop at resilient clip at card under the return spring effect; Last contact chip is provided with the copper post, and following contact chip is provided with down the copper post, upper and lower copper post vertically over against.
As preferably, be provided with plastic column in the said mounting groove, following contact chip passes through the plastic column riveted and fixed in the mounting groove of installation bracket.
Compare with existing vehicle steering horn switch, the utlity model has following advantage:
1, simple in structure, to make easy to processly, cost is low.
2, this vehicle steering horn switch contact is two copper styletable faces, and contact area is big, can bear bigger electric current, has avoided phenomenons such as ablation, so this switch has functional reliability preferably.
3, this vehicle steering horn switch can be fixed on the steering wheel body, and without the plug lead, dismounting is compared the switch that is arranged on the horn hood simultaneously and also shortened the connection conductor length easily when the dismounting horn hood.
Description of drawings
Fig. 1 is the assembling sketch map of the said vehicle steering horn switch of the utility model;
Fig. 2 is the circuit theory diagrams of this vehicle steering horn switch;
Fig. 3 is the cross-sectional schematic at this vehicle steering horn switch spring base place.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this vehicle steering horn switch by following contact chip 4, go up contact chip 1, return spring 7 and installation bracket 9 and form, following contact chip 4, last contact chip 1 and installation bracket 9 all take the shape of the letter U.Installation bracket 9 upper surfaces offer mounting groove 12; Six resilient clips 8 and five plastic columns 11 are set in mounting groove 12; Respectively offer six square openings 5 at following contact chip 4 with last contact chip 1 corresponding resilient clip 8 places; Offer five circular holes 6 at following contact chip 4 corresponding plastic columns 11 places, resilient clip 8 passes down the square opening 5 on the contact chip 4, and plastic column 11 passes down the circular hole 6 on the contact chip 4 simultaneously; In the mounting groove 12 of installation bracket 9, resilient clip 8 passes the square opening 5 on the contact chip 1 to following contact chip 4 again through plastic column 11 riveted and fixed.As shown in Figure 3; Return spring 7 is located at down between contact chip 4 and the last contact chip 1; Its upper end contacts with last contact chip 1; Its lower end is supported on the bottom 10a of the spring base 10 of installation bracket 9, and the bottom 10a of four spring bases 10 all is higher than the upper surface 4a of contact chip 4 down, and last contact chip 1 touches on the dop of resilient clip 8 at card under the effect of return spring 7.Following contact chip 4 upper surfaces are fixed with four following copper posts 3, last contact chip 1 lower surface be fixed with four go up 2, four on copper posts go up copper posts 2 and four following copper posts 3 vertical respectively over against.
As shown in Figure 2, during use, following contact chip 4, go up contact chip 1, loudspeaker 14 and power supply through lead 13 series connection, last contact chip 1 makes four pairs of following copper posts 3 be in released state with last copper post 2, i.e. loudspeaker operating circuit disconnection under the support of return spring 7.Do the time spent when last contact chip 1 receives downward external force, last contact chip 1 moves downward, and copper post 3 is contacted with last copper post 2; The loudspeaker operating circuit is connected, and loudspeaker 14 are rung, after unclamping; Return spring 7 makes down copper post 3 separate with last copper post 2, and the loudspeaker operating circuit is broken off.
