Abstract
The utility model relates to a vehicle adjustable switch, particularly a switch used for regulating lighting angle of a head lamp of a vehicle. The utility model comprises an outer shell and a knob extended out of the outer shell, wherein, the knob is connected with the outer shell by a rotating shaft, one side of the knob is connected with a movable contacting piece, and the movable contacting piece can rotate following by the knob and can select a conducting position on a fixed contact piece. In order to simplify the manufacturing technology and reduce the cost, the fixed contacting piece is attached at the metal conducting area of a printed circuit board.
Description
The utility model relates to a kind of automobile-used adjustment switch, especially adjusts the switch of car headlamp light angle.
Existing automobile-used adjustment switch comprises shell and the knob that stretches out from shell, and knob is connected with shell by rotating shaft, and a side of knob is connecting a movable contact spring of selecting conduction position with knob and on fixed touching plate.During work, stir knob that is movable contact spring and on fixed touching plate, select different conduction positions, rotate different light angles thereby make stepping motor drive headlamp.Problem is in order to guarantee the relative positional accuracy between the moving fixed touching plate, and fixed touching plate need adopt the progressive die punch forming process usually, like this, the not only investment maintenance cost height of equipment needed thereby frock, and material (consumption copper) cost height, technology is also complicated.
The purpose of this utility model is to provide a kind of automobile-used adjustment switch, is guaranteeing under the prerequisite of serviceability, and it can reduce manufacturing cost, simplified processing process by the improvement to fixed touching plate.
The technical scheme that realizes the utility model purpose is when comprising aforementioned formation, and its distinctive feature is: fixed touching plate is attached to the metal conduction district on the printed circuit board (PCB).
And the conducting district can have 3~6.The conducting district is for covering the copper floor, and the surface of covering the copper layer is a nickel coating, and each conducting district is " L " shape mutually and is interrupted coupling.
In the technical program,, fixed touching plate saved the investment and the maintenance cost of expensive tooling devices such as progressive die owing to adopting printed circuit board (PCB); All be made of copper owing to existing fixed touching plate integral body again, in order to guarantee enough rigidity, fixed touching plate need have suitable thickness, i.e. the copper loss height, and in the technical program, the rigidity of fixed touching plate mainly guarantees by the insulation board that constitutes printed circuit board (PCB), and the conducting district just is covered in covers the copper floor on the insulation board, thereby has reduced copper loss significantly, meanwhile, because the evenness of printed circuit board (PCB) more easily guarantees, so, also just be easier to satisfy the relative positional accuracy that moves between the fixed touching plate.Through adjusting, the technical program can reduce cost 20% at least.
Below the utility model is described in further detail with the structure accompanying drawing.
Fig. 1 is the stereogram of the utility model bulk shape.
Fig. 2 is the stereogram that unloads the moving fixed touching plate assembly behind the decapsidate.
Fig. 3 is the stereogram of movable contact spring and knob structure.
Fig. 4 is the front view of the moving fixed touching plate structure of signal.
Fig. 5 is the sectional view along fixed touching plate A-A place among Fig. 4.
With reference to Fig. 1~Fig. 5, this automobile-used adjustment switch comprises shell 2 and the outer group of knob 1 that stretches out from shell 2, and knob 1 is connected with shell 2 by rotating shaft 5, and a side of knob 1 is connecting a movable contact spring 6 that rotates and select conduction position with knob 1 on fixed touching plate.
The rotating shaft 5 of described knob 1 is the projection (integral molded plastic moulding) of knob 1 itself preferably.One side of knob 1 has a pair of draw-in groove of putting relatively 7, and the top of movable contact spring 6 is installed in the draw-in groove 7, and the rotating shaft 5 of this side is simultaneously also passed the default hole in the middle of the movable contact spring 6 and adopted ultrasonic phase of wave riveted joint in addition, also can use pin 9 or screw.For simplified manufacturing technique, reduce cost, fixed touching plate is attached to the metal conduction district 3 on the printed circuit board (PCB) 4.
Described conducting district 3 can have 3~6, the conducting district manufactures to cover copper floor 10 on printed circuit board (PCB) 4, the surface of covering copper layer 10 is a nickel coating 11, to strengthen its resistance to wear, each conducting district 3 is " L " shape mutually and is interrupted coupling, this mainly designs for the operating characteristic that adapts to the stepping motor that drives headlamp, because stepping motor can not cut off the power supply when a kind of operating state is converted to another operating state, so it is corresponding with the fixed touching plate that is the coupling of " L " interruption, 2 contacts 8 are arranged on the movable contact spring 6, when one of them contact 8 goes to next conducting district 3, another contact 8 still rests on former conducting district 3, promptly at movable contact spring 6 when a conducting district 3 switches to another conducting district 3, stepping motor the dead electricity phenomenon can not occur.
Claims (2)
1, a kind of automobile-used adjustment switch, especially adjust the switch of car headlamp light angle, comprise shell and the knob that stretches out from shell, knob is connected with shell by rotating shaft, one side of knob is connecting a movable contact spring of selecting conduction position with knob and on fixed touching plate, it is characterized in that: fixed touching plate is for attached to the metal conduction district on the printed circuit board (PCB).
2, adjustment switch according to claim 1 is characterized in that: the conducting district has 3~6, and the conducting district is for covering the copper floor, and the surface of covering the copper layer is a nickel coating, and each conducting district is " L " shape mutually and is interrupted coupling.
