Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a wiring device in which wire end fixing means using coil springs are provided at at least two locations on a wiring board surface.

(Prior art) When making a wiring harness, pins and the like are set up at predetermined positions on the wiring board to match the wiring diagram, and pins are placed at the ends of the wires.
It is necessary to provide means for securing the wires.

Conventionally, as means for fixing the ends of the electric wire, there is a method in which both ends of a coil spring are fixed on the wiring board, and the electric wire is inserted and sandwiched between adjacent coils.

(Problem to be Solved) However, the wire end fixing means described above can only handle wires of a specific diameter, and when the diameter of the wire changes, the installation length of the coil spring must be changed and the wire fixed again, or depending on the diameter of the wire. It is necessary to replace the coil spring with a new coil spring, and the adjustment and replacement work is time-consuming. It is an object of the present invention to provide a wiring device that can easily adapt to changes in wire diameter.

(Means for Solving the Problems) The present invention provides a U-shaped fixing member that is attached to a wiring board and has its listening side facing upwards on the board surface, and a U-shaped fixing member that is attached to a wiring board, and a U-shaped fixing member that is attached to a wiring board with the listening side facing above the board surface. A wiring device characterized in that it has a wire end fixing means that includes an inserted coil spring and a means that is provided on the fixing member and adjusts the pitch of the coil spring.

(Function) The pitch of the coil spring is set to the optimum value by operating the adjusting means according to the diameter of the electric wire to be laid. That is, the coil spacing of the coil spring is adjusted to be slightly narrower than the wire diameter. Then, insert the wire between adjacent coils.

(Example) In FIG. 1, the end fixing means 33 of the electric wire W
Four pins 2 are provided on the surface of the wiring board 1, and two pins 2 are provided upright.

The fixing means 33 includes a U-shaped fixing member 33b that is attached to the board 1 with screws 33a and has its open side facing upward, and this fixing member 33.
Coil spring 33 inserted between opposite sides of b
c, and means 33d for adjusting the coil spacing l of this coil spring 33c.

Note that the adjustment means 33d in this embodiment is
Screw means 33e (external screw in the embodiment) provided in 3b
This makes it possible to adjust the coil spacing l of the coil spring 33c.

Therefore, when doing wiring work, the coil spacing l
Adjust and set it to be slightly narrower than the diameter of the electric wire W to be handled.

When fixing the end of the electric wire W to the fixing member 33, the electric wire W is placed in a direction substantially perpendicular to the direction of expansion and contraction of the coil spring 33c, and the electric wire W is fixed to the fixing member 33.
Insert the wire between the coils from the open side of the U-shape 3b (that is, lower the wire from top to bottom in FIG. 3 and insert it).

At this time, since the coil spring 33c has a circular cross section and is an elastic body, the electric wire W
Even if the direction of the electric wire W is not made to match the spatial direction between the coils, the electric wire W can be quickly guided and inserted between any of the coils without getting caught in the coils, and the electric wire W will not be damaged. Moreover, since the electric wire W can be tightly held, even if the electric wire W is pulled during wiring, the electric wire W is difficult to come off from the fixing means 33. Furthermore, the coil spacing l is set narrower than the wire diameter, and the sheathing of the inserted wire W is compressed by the coil, so even if multiple wires W are inserted between the same coils, the pinching force will be reduced. However, there is no advantage that the electric wire W will easily come off from the fixing means 33 due to the tensile force applied to the electric wire W during wiring.

Also, after the wires are wired and tied at desired points with adhesive tape or other lashing material, the wires W are removed from the board 1, but at this time, the coil springs 3
The electric wire W sandwiched between the coils 3c can be easily removed without damaging it.

The above description is an example. For example, when this wiring device is used as an accessory device of a wiring robot, the screw means 33e should be driven by power, and by controlling its position, The coil spacing l of the coil spring 33c may be arbitrarily adjusted. Further, the adjusting means 33d may be, for example, a solenoid, and the coil spacing l may be changed by the protrusion and retraction of the rod. Furthermore, the adjustment means 33
d may be a telescopic cylinder device, and the coil interval l may be changed by moving the telescopic side member in and out. It goes without saying that replacement of each component with equivalents is also included within the technical scope of the present invention.

(Effects of the Invention) As described above, the present invention utilizes the coil spring 33c as the wire end fixing means 33, and the coil pitch of the coil spring 33c can be changed by the adjusting means 33d. Even if the diameter of the wire changes, there is no need for the laborious work of adjusting the fixing positions at both ends of the coil spring and fixing it again, or replacing the coil spring with a coil spring that matches the diameter of the wire, as in the conventional case. That is, since the coil pitch can be easily changed even if the wire diameter changes, the wiring apparatus of the present invention is particularly effective when wiring work is automated using an industrial robot or the like.
