However, this electric wire connecting device 30 has a configuration in which the conductive wire 31a is fixed in a straight line to the flat plate-shaped current carrying body 33 without deforming the conductive wire 31a using the plate spring 34, so that it is difficult to connect the conductive wire 31a to the current conducting body 33. The contact stability with the plate 33 was poor, and the conductive wire 31a easily came off after being fixed.

The present invention has been made in view of the above-mentioned drawbacks, and it is possible to make good contact between the conductive wire and the current-carrying body of the power cable, and to prevent force from being applied to the power cable in the direction of disconnection after the connection is fixed. The purpose of the present invention is to provide a wire connecting device that does not easily come off even when the wire is connected.

[Means for Solving the Problems] In order to achieve the above object, the electric wire connecting device of the present invention connects two power cables 10 and 1.
A wire connecting device that connects two ends of the power cable includes a current carrying body 2 that contacts a conductive wire 10a of the power cable to establish electrical continuity, and a movable member that bends the conductive wire 10a at a predetermined angle with respect to the current carrying body 2. It is characterized by comprising a conductor 3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a cutaway front view showing an embodiment of a wire connecting device according to the present invention. Openings 1a, 1a are opened at both ends of the housing 1. Further, inside, a substantially U-shaped current carrying body 2 made of a conductive material is provided continuously between the openings 1a. Both sides 2a of the current-carrying body 2 have holes 2b communicating with the openings 1a, and a conductive shaft 3a of the movable conductor 3 is provided.

The movable conductor 3 has a hole 3b communicating with the hole 2b and is rotatable downward about a conductive shaft 3a. Further, a set screw 4 is provided at a position above each movable conductor 3 in the base portion 2c of the current-carrying body 2. The lower end 4a of this set screw 4 contacts the upper end of the movable conductor 3, and by screwing the upper end 4b through the through hole 1b provided in the upper part of the housing 1, the movable conductor 3 is rotated downward.

Next, the operation of the wire connecting device having the above structure will be explained. Power cable 10,1 to be connected
0, the end portion is peeled off to expose the conductive wire 10a. Next, the ends of the power cables 10 are respectively inserted into the openings 1a of the device. Thereby, the conductive wire 10a is inserted into the hole 2b of the current-carrying body 2 and the hole 3b of the movable conductor 3.

After that, when the set screw 4 is screwed in, the movable conductor 3 tilts downward from the conductive shaft 3a, as shown in the partially enlarged perspective view of FIG. The hole 3b of the movable conductor 3 is inclined. As a result, the linear shaft-shaped conductive wire 10a is bent at the end of the fixed current-carrying body 2 and pressed against the peripheral walls of the holes 2b and 3b, resulting in good contact between them. Here, the bending force in particular presses the conductive wire 10a against the portion A in FIG. 2, that is, the lower end of the hole 2b, so that good contact can be made at this portion. In this way, in each power cable 10, when the conductive wire 10a is inserted and the set screw 4 is screwed in, the conductive wire 10a portions are electrically connected to each other via the movable conductor 3 and the current carrying body 2. Become.

A protruding piece 20a of the current-carrying body 20 is located at the bottom of each opening 1a. Projecting piece 2
An arcuate portion 20b having a predetermined diameter is formed at the inner end of Oa. The protruding piece 20a of the current-carrying body 20 has a rotating shaft 2
0c is provided. A fixed lever 22 provided outside the housing 1 is rotatable around this rotating shaft 20c.

The fixing lever 22 is provided with a fixing pin 23 inside the housing 1 at a position a predetermined distance from the rotating shaft 20c depending on the thickness of the conductive wire 10a. This fixing pin 23 is rotatable in an arc centered on the rotating shaft 20c. A presser plate 25 is provided above the fixing pin 23 and is biased downward by a spring member 24 .

The operation of connecting the power cables 10 with the above configuration will be explained. The ends of the power cables 10 are respectively inserted into the openings 1a of the device. After this, fix lever 2
2 is rotated, the fixing pin 23 is tilted around the rotating shaft 20c. As a result, the linear axial conductive wire 1
0a is bent by a fixing pin 23, and in particular, the bending force presses the conductive wire 10a toward the circular arc portion 20b, allowing good contact at this portion. The respective power cables 10 are then electrically connected to each other via the current-carrying body 20.
