Technical Field
The present invention relates to a wiring unit.
Background
The wiring unit described in patent document 1 is provided in an automatic transmission of an automobile, and includes a plurality of wires and a holding plate having a support surface formed thereon for supporting the wires. The holding plate is integrally formed with a pressing portion. The pressing portion includes a side sheet protruding from the support surface side and a pressing piece bent at a substantially right angle from an upright end of the side sheet, and is maintained in a substantially L-shaped form as a whole. Each electric wire is inserted and held between the pressing piece and the supporting surface from the side in a press-fit manner in a state of being inserted through the protective pipe. The wires are fastened to the holding plate by the binding band on both sides in the longitudinal direction with the pressing portion interposed therebetween.
Disclosure of Invention
Problems to be solved by the invention
In such a wiring unit, since it is necessary to perform a work of shaping each electric wire to a degree that the electric wire conforms to the form of the wiring path (wiring work) before the bundling work of the binding tape, there is a problem that the work is complicated and the burden is large. In the above configuration, the floating of each electric wire can be restricted by the pressing portion. However, each electric wire needs to be inserted into a working space between the pressing piece and the supporting surface from the side, and the electric wire is sometimes difficult to be applied in an environment where the working space cannot be secured.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a wiring unit capable of reducing spatial restrictions and facilitating wiring work.
Means for solving the problems
The wiring unit of the present invention is characterized by comprising: a plate having a support surface for supporting the electric wire; and a holding member that holds the electric wire between the holding member and the support surface; the holding member includes a plurality of holding pieces protruding from the support surface side, and each of the holding pieces is pressed down from an upright posture in which the holding piece is erected so as to define a space for guiding the electric wire to the support surface side between the holding pieces, and is deformed to a holding posture in which the holding piece is pressed against the support surface side to restrict the electric wire from floating from the support surface.
Effects of the invention
In the standing posture in which the holding pieces stand up, the electric wire can reach the supporting surface while being guided by the guiding space between the holding pieces, and therefore, the electric wire can be easily wired at a predetermined position on the supporting surface by performing an operation of inserting the electric wire between the holding pieces. In particular, the wiring operation can be omitted in advance.
Further, since the opening side of the guide space between the holding pieces facing the support surface is opened to serve as the wire insertion port, a working space for inserting the wire can be secured without any problem. Further, since each holding piece is pressed down from the standing posture and deformed to the holding posture for restricting the electric wire from floating from the support surface, each holding piece does not protrude greatly from the support surface in addition to the electric wire being stably held on the support surface, thereby saving space.

Detailed Description
Preferred embodiments of the present invention are described below.
Preferably, each of the holding pieces is capable of bending deformation in a direction to approach and separate from each other, and includes a tapered expanding portion that expands toward the wire insertion opening of the guide space in the standing posture, and a temporary holding portion that restricts the wire from floating from the support surface in a width narrowing portion of the expanding portion on the opposite side of the wire insertion opening. According to the present configuration, the electric wire can smoothly reach the support surface along the expanded portion. In addition, since the temporary holding portion restricts the electric wire from floating from the support surface, the electric wire can be prevented from being accidentally slipped out from the guide space when each holding piece is in the standing posture.
Preferably, the holding member is formed of a linear member, and the holding pieces are twisted with each other in the holding posture and bound. Since the bundle diameter of each holding piece can be adjusted in this manner, the radial dimension and shape of the entire electric wire can be matched. Further, since the holding member is formed of a linear member, it is easy to perform twisting processing and can contribute to weight reduction.
Preferably, in the holding posture, the portions of the holding pieces twisted and bound to each other are arranged in a state of being pressed against the electric wire side. In this way, the portions of the holding pieces twisted and bound with each other do not protrude greatly in the direction away from the support surface, and therefore, the restriction on space can be further reduced.
Preferably, the holding member includes a coupling piece that couples the holding pieces to each other, the coupling piece being disposed along a surface of the plate opposite to the support surface, and the holding pieces being inserted into a plurality of holes formed in the plate and positioned. Thus, the holding member can be stably attached to the predetermined position of the board with good reliability.
