[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fixed contact piece of a slide switch which can be used for a vehicle interior light and the like and its external connection means.

[0002]

2. Description of the Related Art As a slide switch of this type, a conventional slide switch has been proposed by, for example, the applicant of the present invention.
There was one described in Japanese Patent No. 12. In this conventional technique, in a slide switch provided with a movable contact piece on a sliding body, a knob is projected outside from a hole of an upper plate of an insulating base formed into a substantially U-shaped cross section, and is inserted into a recess of the insulating base. A plurality of small-width conductive members provided with an insulative slidable body movably, a movable conductor projecting with a spring disposed under the slidable body, and a bump contact portion slidably contacting the movable conductor. A slide switch in which plates are fixed in parallel to the lower part of the insulating base.

[0003]

In the above-mentioned conventional technique, the bus bar, which is a fixed contact piece for the power source and other circuit parts, must be directly wired on the insulator.
Since the place of application is greatly limited and accidental contact with other members occurs due to the protruding part of the fixed contact piece, it is easy to cause accidental contact with other members, and the extended exposed part of the fixed contact piece remains insulated over the entire length. There are many problems that it is troublesome and costly because it is necessary to prevent concealment due to concealment and short-circuiting.

In order to eliminate the above-mentioned problems, the present invention enables a one-touch connection via a plug-in jack by a plug portion integrally formed on a fixed contact piece between a power supply line and a load by a slide switch operation, and The purpose is to prevent the fixed contact plug part from moving.

[0005]

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is provided with a sliding body movably provided in the recess of the insulating base by directing a knob from the elongated hole connected to the recess of the insulating base to the outside. In forming a slide switch in which a movable conductor self-projecting is provided in the lower part of the sliding body, a plurality of fixed contact pieces straddling the movable conductor are provided in parallel, and the outer surface of which is covered with an insulating plate. , A rear vertical portion of at least one of the fixed contact pieces is folded up in an L-shape in the thickness direction of the fixed contact piece to form a rising support piece and a plug portion connected to the upper part thereof with a vertical length of one character And a guide piece for guiding a plug-in jack to be fitted into the plug portion is projectingly provided on the outer surface of the insulating plate, and a rear longitudinal groove is inserted into the base portion of the plug portion to form the plug portion of the plug portion. This was achieved by positioning the base.

[0006]

[Function] Since the rising support piece integrally projecting from the fixed contact piece and the plug portion are one letter in the vertical direction when viewed from the jack insertion direction,
The plug part does not inadvertently bulge or warp due to insertion and removal of the jack or disturbance, and the base part of the plug part can be positioned by the edge of the vertical groove of the guide piece for insertion guide of the plug-in jack, and also in the thickness direction. Can be reinforced. Further, the fixed contact piece itself can be embedded in a fixed contact piece positioning groove formed on the facing surface of the base projection or the base or the insulating plate, or can be positioned strictly by a screw or other well-known localization means.

Therefore, the fixed contact piece does not move unintentionally due to a disturbance such as sliding friction caused by the movable contact piece, and the plug portion does not move when the separate plug-in jack is inserted or removed. Then, for example, one plug part is connected to the power source positive electrode, and the other plug part is connected to the power source negative electrode through the door switch and a load such as a lamp in series, and the sliding member is moved and fixed by the movable contact piece. By controlling the conduction between the contact pieces, for example, the in-vehicle lamp can be manually turned off or turned on when the door is opened.

Further, as a fixed contact piece of the slide switch, a part of a strip-shaped narrow conductive plate for wiring called a so-called bus bar is used, and by fixing a plurality of them in parallel, a valley between these fixed contact pieces or a fixed portion is fixed. The movable conductor, which is operated by a knob, elastically falls into a valley in the valley between the collision contact portions formed on the contact piece, and the fixed contact pieces on both sides of the movable conductor can be short-circuited to be switched on. Then, the movable conductor operated by the knob is elastically slid into the valley between the fixed contact pieces (conductive plates for wiring), so that the knob operation as the slide switch causes a click action, that is, a snap action.

Further, by removing the movable conductor from the above-mentioned valley, the switch is turned off, and by dropping the movable conductor in another valley, it serves as a single-pole double-throw / double-pole double-throw changeover switch.
