Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a lead wire holding device, and is particularly applicable to instrument devices installed in vehicles such as motorcycles, ships, agricultural machinery, etc., and used in a vibrating atmosphere. The present invention relates to a lead wire holding device for holding lead wires routed on the back side of a similar mounting board.

[Conventional technology]

Generally, instruments such as vehicles are provided with mounting holes in the mounting board, as known from Utility Model Publication No. 57-32416, and the instruments are fitted into these mounting holes via buffer members and fixed with fixtures. ing. Generally, the lead wires that are routed from the instruments to the back side of the mounting board are formed by bending a flexible synthetic resin clamp material into a curved shape, overlapping both ends, and securing the lead wires with screws. It is held by a clamp portion to which it is fixed.

[Problems to be solved by the invention] In the above-mentioned conventional technology, after holding the lead wire in the clamp material, both ends of the clamp material must be fixed with screws, which requires a complicated assembly process, and it is difficult to use the clamp material. There were problems in that it was easy to be restricted in the places where it could be fastened, and the number of parts increased.

Therefore, an object of the present invention is to provide a lead wire holding device that does not require screw fixing operations and can reduce the number of parts.

[Means for solving problems]

In the present invention, an instrument is fitted into a mounting hole provided in a mounting board through an elastic buffer member, and an elastic clamp part is integrally formed from the buffer member and extends almost along the back side of the mounting board. A lead wire insertion portion is provided at a portion of the clamp portion that faces the back surface of the mounting board.
