Abstract

PROBLEM TO BE SOLVED: To dispense with an excessive component such as marking tape by setting and controlling the cord length of the part extended from a switch body to a proper value. SOLUTION: As the first procedure, the leading part of a cord 2 is covered with a tube 5 having a fixed length. As the second procedure, the other part 52 of the tube 5 is positioned to a prescribed position 11 of a lever 1, and a fixing tape 7 is wound on the other part 52 to fix it. Further, as the third procedure, the clamp 3 of a switch body 4 is positioned to one end 51 of the tube 5, and the clamp 3 is caulked to the one end 51. Thus, the cord 2 drawn from the lever 1 is fixed to the switch body 4, and the tube 5 dimensionally controlled to a fixed length is positioned to the clamp 3, whereby the cord length L of the part extended from the switch body 4 is naturally made constant.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever switch such as a combination switch for a vehicle, and more particularly to a lever switch for securing dimensional accuracy when a cord pulled out of a lever is fixed to a switch body using a clamp. A code positioning structure.

[0002]

2. Description of the Related Art Conventionally, for example, a combination switch for a vehicle often has a switch or a volume for operating a lighting system or a wiper system at a tip of a lever, and a cord connected to the switch or the volume is transmitted from the lever to the lever. I was drawing. And the cord pulled out from this lever was fixed to the switch body using a clamp. Conventional techniques of this type include, for example,
Japanese Unexamined Patent Publication No. 8-194221 discloses a device in which a lead wire connected to a rotary switch at the tip of a switch lever is guided to the outside from the middle of the lever and held by a clamp of a switch case.

[0003] In such a conventional lever switch, when the cord is connected to the wiring on the vehicle body side, the cord length of the portion extending from the switch body is set to an appropriate value so that the cord is not loosened or tensioned as much as possible. Must be set and managed. As a procedure for this, conventionally, for example, a mark tape that can be clearly distinguished from the tube is wrapped around a part of the tube covered with the cord withdrawal portion, and a clamp is crimped on the tube based on the mark tape.

[0004]

However, in the above-mentioned prior art, not only is it necessary to set a mark tape as a structural component of the lever switch, but also it takes time and effort to wind the mark tape around the tube. This was one factor that increased costs.

The present invention solves the above-mentioned problem, and in order to set and manage a code length of a portion extending from a switch body to an appropriate value, a lever that does not require an extra component such as a marking tape is required. An object of the present invention is to provide a switch code positioning structure.

[0006]

In order to solve the above-mentioned problems, first, according to the present invention, there is provided a lever switch in which a cord pulled out from a lever is fixed to a switch main body by using a clamp, and a portion where the cord is pulled out is provided. Is covered with a tube of a fixed length, and one end of the tube is fixed to the clamp and the other end is positioned and fixed to a predetermined position of the lever, respectively.

Further, the invention according to claim 2 provides a cord positioning structure for a lever switch, wherein the clamp is coated with a synthetic resin having elasticity.

[0008]

An embodiment of the present invention will be described with reference to the accompanying drawings. First, the configuration indicated by reference numeral 1 in the drawing is a lever. The lever 1 has a knob 12 for operating a lighting system circuit and a wiper system circuit on the distal end side.
The other end 2 of the cord 2 is
2 is soldered.

After the other end 22 is connected to the base 14, the cord 2 is passed through the inside of the lever 1, pulled out from a predetermined position 11 on the base end side of the lever 1, and the drawn portion of the cord 2 is fixed length. And the other end 21 of the connector 6
Terminal 61. One end 51 of the tube 5 is fixed to the clamp 3 of the switch body 4 and the other end 52 is fixed to the predetermined position 11 of the lever 1. The middle of the tube 5 is lightly supported by claws 41 provided on the switch body 4. In addition, clamp 3
The crimped portion is coated with an elastic synthetic resin so that the cord 2 and the tube 5 are not damaged, and the one end 51 of the tube 5 is securely held so as not to fall off the clamp 3. The clamp 3 is fixed to the switch body 4 using screws 8.

The procedure for fixing the code 2 is as follows. First, as a first procedure, the lead-out portion of the cord 2 is covered with a tube 5 having a predetermined length. Next, as a second procedure, the other end 52 of the tube 5 is aligned with the predetermined position 11 of the lever 1, and the fixing tape 7 is wound around the other end 52 and fixed. Further, as a third procedure, the clamp 3 of the switch body 4 is aligned with one end 51 of the tube 5, and the clamp 3 is connected to one end 51.
Caulking. As a result, the cord 2 pulled out from the lever 1 is fixed to the switch body 4, and the length of the cord L extending from the switch body 4 is adjusted by aligning the tube 5, whose dimensions have been controlled to a certain length, with the clamp 3. It naturally becomes constant.

[0011]

According to the present invention, there is provided a lever switch in which a cord pulled out from a lever is fixed to a switch body by using a clamp, wherein a portion where the cord is drawn is covered with a fixed length tube, and one end of the tube is connected to the clamp. In order to set and manage the code length of the portion extending from the switch body to an appropriate value, since the other end is positioned and fixed to the predetermined position of the lever, an extra component such as a marking tape is used. do not need.

[0012] Further, the present invention is characterized in that the clamp is coated with a synthetic resin having elasticity.
The clamp does not damage the cord and the tube, and a large frictional force generated between the coating resin and the tube can securely hold one end of the tube to the clamp, so that the tube does not fall off the clamp.
