Problems solved by technology

resulting in Figure 23 The distance in the middle height direction (up and down direction) will also become longer
[0005] Due to the above reasons, since the space for arranging the flexible printed wiring board 600 will limit the width of the flexible printed wiring board 600, and then the number of wirings will be limited, resulting in a reduced degree of design freedom.

Abstract

Provided is a flexible printed wiring board in which the number of wires can be increased even when used in a narrow installation space while provided in a self-standing manner, and which thereby allows for a greater degree of design freedom. This flexible printed wiring board (100) is used while one end side and the other end side thereof in the longitudinal direction are respectively fixed to one member and to the other member among two members that move relative to each other, in a state in which the flexible printed wiring board is folded so as to be curved in the longitudinal direction thereof. The flexible printed wiring board 100 is characterized by being provided with a plurality of wiring board units (100A, 100B) which are formed in a state of being curved in the widthwise direction and have a plurality of wires on a flexible insulated substrate, wherein neighboring wiring board units are partially coupled to each other at the side-edge sides in the widthwise direction.

Description

technical field [0001] The present invention relates to a flexible printed wiring board using a flexible insulating substrate. Background technique [0002] Conventionally, various types of wiring have been used for electrical connection between components included in industrial equipment, robots, game machines, etc., mainly in various electronic equipment such as communication and video equipment. In particular, cable carrier tubes (registered trademarks) are used, for example, in locations where smooth movement of components is required within the facility (see Patent Document 1). However, since this technique requires a member for supporting the cables, etc., a large space is required for the arrangement space of the cable carrying pipe. On the other hand, the arrangement space can be reduced by using a flexible printed wiring board. However, when a normal flexible printed wiring board is used as it is, the flexible printed wiring board will hang down. Therefore, depen...
