. (54) SOUND CONTROL BUTTON KNOT

one

The invention relates to mechanical engineering, more specifically to vehicle electrical systems.

Known button control unit sound signal mounted on the steering wheel, containing a spring-loaded movable contact located on the button, a fixed contact mounted in the steering wheel in a shell of insulating material at a distance DT of the movable contact, and. the gasket installed in the steering wheel frame with the ability to interact with the movable contact when you press the box connected to the car body til The disadvantage of the known control button is the complexity of the design.

The purpose of the takobread is to simplify KOHCTW instructions.

The goal is achieved by the fact that in a known device, the mobile contact is electrically connected by means of a spring installed in an insulating sheath passing through the frame by the SIGNAL signal

with fixed contact, the moving and fixed contacts have identical profiles, and the fixed contact forms the base 5 of the insulating sheath.

In this case, the knot is equipped with elastic spear teeth, the ends of which are made in the form of a hook, mounted on the winding shell with the possibility of

10 action with fixed contact and spring.

In addition, it is equipped with additional coupling teeth, made on the insulating sheath

15 interaction with the steering wheel frame.

FIG. 1 shows a button, a section along the axis; FIG. 2 is a section A-A in FIG. one; in fig. 3 - view along arrow B

Claims (3)

20 in FIG. one; in fig. 4 - section bb in fig. 2; in fig. 5 - section GG in figure 2; in fig. 6 is a design variant applicable to a steering wheel with closed spokes; in fig. 7 - the same, d; w steering wheel. The control button 1 is located in the frame 2 of the rupee kopeg, which can be fastened to the steering wheel by using the pin 3 and fixed by a lock nut 4 .. Button 1 is fixed; with the possibility of mainly axial movements with the help of a locking peg 5 with palish 6, turning around with hook-shaped tips 7 with the possibility of elastic engagement With corresponding valves 8, made in the steering wheel frame 2 Button 1 contains an attachment contact 9 consisting of a metal plate the central part of which It is a disc with two tabs 10, curved under direct fragrance. The said movable contact is mounted in the button with the aid of the seat 11, preventing the contact from rotating. The movable contact is installed side by side with a puck 12 mounted on pin 3 and grounded. The main contact is electrically connected to the fixed contact 13, connected in turn to the signal circuit. Between the movable contact 9 and the fixed contact 13, several springs 14 are installed, which are partially seated in the corresponding cylinder bodies 15 made into the skin 16 of an insulating material. The springs 14 exit the shells 15 with OPPORTUNITY; interacting with the tabs of the movable contact 9. On the opposite side of the spring 14, they interact with the fixed contact 1G with the help of the tabs 17. The fi1: sirovanny contact 13 is built into the insulating skin 16, where it is held in place with in hook forms. The profiles of the moving fixed contacts are zdenichnymi and vyamimosmenemym. The casing 16 is mounted on the frame 2 of the steering wheel, for this it has additional coupling teeth 19 with the possibility of their engagement with the corresponding 1 gates 8. The casing 16 has a pin 20 for automatic reversal of the direction indicators. Due to the fact that the pin must have a ynpyi-awn in the axial direction, the casing on its own; the lower end has a tongue in the form of a part of the circle 21. In the embodiment of the invention (Fig. 6), the fingers 22, which are integral with the housings 15, play the role of the locking device of the housing 16. In the embodiment of the invention shown in FIG. 7, the button has a movable co-tact 9 and a fixed contact 13, and said springs 14 are placed between them, while case 16 has fingers 22. Pressing the control button 1 causes the movable and fixed contacts to join. In accordance with the invention, it becomes possible to substantially simplify the construction of the sound control button. Claim 1. Sound button control unit mounted on the steering wheel, containing a spring-loaded movable contact located on the button, fixed contact mounted in the steering wheel in the shell of. insulating material at a distance from the movable contact, and a gasket installed in the steering wheel frame that can interact with the movable contact when the button is pressed and connected to the vehicle body, characterized in that, in order to simplify its design, the movable contact is electrically connected by means of a spring installed in an insulating shell, passing through the frame of the steering wheel, with a fixed contact, the moving and fixed contacts having identical profiles, and the fixed end tact forms the base of the insulating shell. 2. A knob according to claim 1, characterized in that it is provided with elastic coupling teeth, the ends of which are hook-shaped, mounted on an insulating shell with the possibility of interaction with a fixed contact and a spring. 3. Node under item 1, which is different from that; It is equipped with additional coupling teeth made on the insulating shell with the ability to interact with the steering wheel frame.
