Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a connecting fitting for connecting a power feeding support material such as a raceway or a cable duct to each other in an expandable and contractible manner.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, this type of connecting fitting is known to have means for interposing a member (hereinafter referred to as a coupling) for connecting the ends of the power feeding support member P with each other and fixing them with screws. There is. According to this connecting means, a long hole-shaped screw insertion hole P1 is opened at one bottom of the power feeding support member, and the locking screw Q1 protruding from the bottom of the coupling Q is inserted into the screw insertion hole P1 to make the length. It was connected freely.

In addition, when such a coupling is not used, there is also a means of providing a free pipe called a so-called plica tube on the ends of the power feeding support member (not shown).

[0004]

[Problems to be solved by the device]

 However, according to the conventional coupling means using a coupling, there is a problem that it takes time and labor to open a screw insertion hole in the bottom portion of the power feeding support member such as a raceway.

Further, when the flexible pipe is used, the cable must be passed through the flexible pipe at the time of wiring, which leaves a problem that the wiring work is troublesome.

Therefore, the present invention has been devised to solve the above-mentioned problems, and it is possible to easily connect the power feeding support members such as a raceway to each other, and also to connect the wiring work without any support. The purpose is to provide metal fittings.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is directed to a pair of connecting and fixing bodies 1 arranged inside the bottoms of the end portions of the power feeding support material having a substantially U-shaped cross section, and a net between the connecting and fixing bodies 1. A connecting fitting for connecting the power feeding support members to each other by the flexible connector 2 which connects the fixed connectors 1 to each other by fixing the flexible connector 2 to the connector 1 so that the length can be adjusted. This is because the slender long hole 2A is provided, and the universal joint 2 is crimped and fixed to the joint fixed body 1 by the screw 3 screwed to the universal joint 2.

Further, each connecting and fixing body 1 is crimped and fixed to the bottom of the power feeding support member with a screw 3, and the bond wire 4 for conducting the power feeding support members to each other is connected to the screw 3 as means for solving the problem. To do.

[0009]

[Action]

 That is, according to the first means of the present invention, the universal connecting body 2 connects the connecting and fixing bodies 1 to each other with their lengths adjustable. The connected fixed body 1 connects the power feeding support members such as the raceway P to each other.

Further, in the second means, the screw 3 for crimping the connection fixing body 1 to the raceway P conducts electricity between the power feeding support members via the bond wire 4.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Reference numeral 1 shown in the figure is a connecting and fixing body that connects the power feeding support members such as the raceway P (see FIG. 1). This connecting and fixing body 1 is to be inserted into the end of the raceway P having a substantially U-shaped cross section. In the illustrated example, the connecting and fixing body 1 is also substantially U-shaped along the sectional shape of the raceway P. Is formed. Then, the bottom of the connecting and fixing body 1 is overlapped on the bottom of the raceway P, and the screw 3 protruding from the bottom of the connecting and fixing body 1 is crimped to the bottom of the raceway P, whereby the raceway P and the connecting and fixing body 1 are connected. Is fixed (see FIG. 2).

Reference numeral 2 is a universal connecting body that connects the connecting and fixing bodies 1 by screwing them together. This universal connecting body 2 is provided with a slide long hole 2A for fixing the flexible connecting body 1 in a freely adjustable length, and the universal connecting body 2 is crimped to the connecting fixed body 1 by a screw 3 screwed to the universal connecting body 2. Fix it. At this time, the screw 3 inserted into the slide long hole 2A can adjust the connecting position between the connecting and fixing bodies 1 in the length of the universal connecting body 2 (see FIG. 3). Further, the universal connecting body 2 is formed in a substantially U-shaped cross-section like the connecting fixed body 1. As described above, by forming the connecting and fixing body 1 and the free connecting body 2 in a substantially U-shaped cross section and overlapping them on the bottom of the raceway P, there is an advantage that the strength of the connecting portion can be increased.

The raceways P are electrically connected to each other via bond lines 4. This bond wire 4 is screwed to the connection fixing body 1 and is connected to a screw 3 which is crimped to the bottom of the raceway P. The tip of the screw 3 should be used to scoop off the coating on the bottom surface of the raceway P. This ensures reliable conduction (see FIG. 2).

The universal connecting body 2 shown in FIG. 4 is of a type integrally formed with the one connecting and fixing body 1. By integrally forming the connecting and fixing body 1 and the universal connecting body 2 in this manner, there is an advantage that the number of parts to be carried by an operator can be reduced.

[0015]

[Effect of device]

 The present invention achieves the original purpose by being configured as described above. That is, according to claim 1, there is no need to open a screw insertion hole in the raceway P or the like, unlike the conventional coupling means using a coupling, and the screw 3 provided in the coupling fixing body 1 and the universal coupling body 2 is provided. Since the power supply support members can be easily connected to each other simply by tightening the, the workability can be improved. Also, since there is no need to use a flexible pipe, the troublesome wiring work of passing a cable through this flexible pipe was eliminated.

Moreover, according to the second aspect, it is possible to ensure the conduction of the power feeding support member, and moreover, this conduction performance is increased with the tightening strength of the screw 3 that connects the power feeding support member. There is also.

As described above, according to the present invention, various power supply supporting members such as a raceway can be easily connected to each other, and various practically useful effects such as no support for wiring work can be obtained.
