Description

  The present invention relates to an electrical component cover that regulates the wiring of cables derived from electrical components attached to a vehicle.

  As an electrical component assembled in a vehicle, for example, there is a back lamp switch. FIG. 5 shows a plan view when the back lamp switch is assembled on the vehicle side, and FIG. 6 shows a side view when the back lamp switch is assembled on the vehicle side.

The back lamp switch 1 includes a head 2 having a hexagonal column-shaped side surface, and a screw portion 3 having a thread formed on the outer periphery for attaching the back lamp switch 1 to the vehicle side. On one surface of the outer periphery of the head 2, a lead-out portion 4 is provided so as to protrude, and a cable 5 is led out from the lead-out portion 4. An operating element 6 is provided at the tip of the screw part 3 opposite to the head part 2. The operating element 6 is pressed by a response portion (not shown) that responds when the gear is put in the back by the user's shift lever operation. Accordingly, the back lamp switch 1 is turned on.
The back lamp switch 1 is assembled to the vehicle side by the screw part 3 being screwed into a female screw part 7 formed in the transmission of the vehicle by an operator.

  Since the back lamp switch 1 is assembled by screwing the screw part 3 to the female screw part 7, variation occurs in the direction in which the lead-out part 4 faces due to the tightening or the like of the operator. For this reason, when the back lamp switch 1 is assembled to the vehicle, the cable 5 is routed through the side of the back lamp switch 1 in the case where the lead-out portion 4 faces in a direction opposite to the proper wiring direction. It is necessary (see the two-dot chain line in FIG. 5).

  When the cable 5 is wired next to the back lamp switch 1 in this way, the back lamp switch 1 is screwed into a transmission provided near the engine, and thus strongly receives engine vibration. In some cases, the cable 5 deviates from the proper wiring position and moves above the head 2 as shown by the solid lines in FIGS. When the cable 5 deviates from the proper wiring position, there is a possibility that it may be damaged by coming into contact with surrounding interferences (not shown).

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an electrical component cover that can prevent a cable led out from electrical components from coming off from an appropriate wiring position even when vibration from the vehicle side is applied. There is to do.

In order to achieve the above object, an electrical component cover according to the present invention includes a screw portion having a screw thread formed on the outer periphery, and a cable led out from the outer periphery to the screw portion. An electrical component cover that is attached to an electrical component that is attached to a vehicle by being screwed to a portion, and has a peripheral wall portion that covers the outer peripheral portion of the electrical component, and an opening portion on one end side of the peripheral wall portion A cover main body having a slit for dividing the peripheral wall portion into a plurality of portions in the circumferential direction, the peripheral wall portion being fitted to an outer peripheral portion of the electrical component through the opening, and the opening portion of the peripheral wall portion The cover main body is engaged with the electrical component with the peripheral wall portion being pushed outward when the peripheral wall portion is fitted to the outer peripheral portion of the electrical component. An engaging claw to prevent it from coming off, Is formed over the other end portion opposite from the opening in the serial peripheral wall portion, and the notch portion of the time of fitting the electrical component in the peripheral wall portion, since the peripheral wall portion so as not to interfere with the cable, The cover main body is provided at the other end opposite to the opening and is provided so as to protrude from the peripheral wall portion, and the cable of the cable is attached to the electrical component in the cover main body. It is provided with the collar part which controls the movement to an other end part direction (Claim 1).

According to the first aspect of the present invention, since the engaging claw is provided on the cover main body, the cover main body is attached to the electrical component in a state of preventing the cover main body from coming off. Since the flange part protruding from the peripheral wall part to the periphery is provided at the other end part on the opposite side to the opening part of the cover body, the cable is about to move toward the other end part due to vibration from the vehicle side such as the engine. However, the movement of the cable can be restricted by the collar portion, and therefore, the cable can be prevented from being detached from the proper wiring position.
