2. Description of the Related Art Slip-on type conductor connecting means are conventionally known for connecting electric power cables. As the connecting means of the cable, for example, Japanese Patent Application Laid-Open No. 2-15
Those disclosed in Japanese Patent No. 5415, Japanese Utility Model Laid-Open No. 2-77868, etc. are known. The power cable connection device of the conventional example has a configuration as shown in FIG. 16, and copper conductor connectors 2 are fixed to the connection ends of the conductors 1 of the two cables to be connected. Is provided. In the conductor connector 2, a large-diameter compression part 3 is arranged on the cable side, an opening 4 for inserting a cable conductor is provided at the center of the compression part, and the conductor 1 is inserted into the opening 4 for compression. However, the electrical continuity between the conductor and the conductor connector is obtained.

An insertion head member 5 is provided at the tip of the conductor connector 2 so as to project therefrom. The insertion head member 5 is inserted into the conductor joint 10 and the locking step portion of the insertion head 5 is provided. 7 is locked to the locking step portion 12 of the conductor joint 10 to fix the conductor connector to the conductor joint. The conductor joint 10 used for inserting the conductor connector and obtaining an electrical connection is a narrow strip-shaped member 10a.
... are arranged in a substantially annular shape, and ring-shaped springs 14 are arranged around them so as to be tightened from the outside. Further, a concave portion 11 is provided on the inner surface of the conductor coupling member 10a arranged in a ring shape, and the insertion head member 5 of the conductor connector is accommodated in the large-diameter hollow portion formed by the concave portion 11. .

The above-mentioned conductor connector is also integrally fixed to the other cable conductor to be connected, and the conductor connectors provided at the connection ends of the two cables are inserted into the conductor joint 10, respectively. Then, the connection portion can be formed. Then, by using a conductor connector connected to the conductor joint, electrical continuity of both cables can be obtained, and a fixing and holding action is exerted in response to a force in a pulling direction applied to the cable. be able to. Further, the power cable connecting device as shown in FIG. 16 constitutes a terminal connecting portion of the power cable, and one conductor connector 2a is attached to the conductor joint in advance, After that, the conductor connector 2 of the other cable 1 is inserted from the other side of the conductor joint 10 so as to connect the cables. As described above, with respect to the portion where the cable is connected by using the conductor coupling 10, like the connection portion of the general cable,
It is covered with an insulating member and fixedly held.

Further, as shown in FIG. 16, one of the conductor connectors arranged at the tip of the cable 1 is used as a fixing member in advance, and the other conductor connector is mounted later. For example, as shown in FIG. 17, a conductor connector of the same shape may be attached to the conductor connector 10 to connect a cable. In the example shown in FIG. 17, the conductor connectors 2 and 2a are configured to have the same shape, and the conductors are electrically connected to each other with the conductor connectors fixed to the ends of the cables 1 and 1a. At the same time, they are able to make connections.

In the state, it is made to close again. At that time, since the conductor joint is inclined, the protrusion having the length L1 is in the state of the diagonal length L2. Therefore, with respect to the length L of the small diameter portion 8, L> L2.
The length of each member must be set so that Therefore, in the power cable connecting device, a large amount of backlash remains at the combined position of the locking step portions of the respective members.

At the connecting portion, only the engaging portions of the engaging step portions of both of the engaging portions bear the tension between the conductor connecting element and the conductor joint. Since the joint is a member made of copper, there is also a problem that the strength is relatively small with respect to tensile force. further,
When inserting and fixing the conductor connector to the conductor joint,
As shown in FIG. 17, when the axes of the two do not coincide with each other, or when a force is applied from the side portion, there arises a problem that the engagement state of the conductor connector with respect to the conductor joint is not properly set. When the strip-shaped member of the conductor joint is in an oblique state with respect to the conductor connector,
There are still problems that the locking step portions cannot exhibit the function of locking each other satisfactorily and that the electrical conduction state cannot be set.

[0008]

SUMMARY OF THE INVENTION The present invention solves the problems of the conventional connecting device as described above.

It is held in a state where there is almost no gap formed between the lower surface of the head and the head.
Then, the tensile stress applied between the insertion-side connector 30 and the locking-side connector 40 forming the connection member acts as a force for compressing the claw member 50, and the insertion-side connector The strength of the connecting portion can be increased by configuring the locking-side connector and the other members provided on them by using stainless steel or iron having high strength.

In the connection member of the present invention, the insertion head of the insertion side connector is inserted into the locking side connector, and the claw member is swung outward through the pin, The connection relationship between both members is set, and in that state, the taper portions provided at the joint portions of both members are the same.

Can be maintained at.

In the connecting member shown in the above embodiment,
The claw member can be configured as shown in FIGS. 11 to 13, and the locking side connector can be configured as shown in FIG. 14. In the modified example of the claw member shown in FIGS. 11 to 13, the pin 52 arranged on the upper part of the main body of the claw member 50a is configured in the same manner as in the case of FIG. 6, but is formed on the lower part of the main body. Lower arc surface 54a
Is configured as a surface with a large radius of curvature. Further, the upper surface 53a of the main body is formed in a flat shape corresponding to the lower surface of the head portion of the fixing bolt member in a state where the claw member is swung outward. Further, as shown in FIG. 13, the angle θ1 formed by the outer surface 55a of the claw member 50a and the tangent line of the arcuate surface 54a is set to a large angle, so that it is inserted into the locking side connector 40. Even when the side connector 30 is inserted and the claw member is opened, a mechanism capable of releasing the locked state of both members can be configured by applying a large force.

Further, in the example shown in FIG. 14, the lower circular arc surface 54a provided on the claw member 50a is made to correspond to the lower circular arc surface 54a.
The curvature of the arc surface 44a is defined, and the tapered portion 45a arranged at the tip of the through hole 42a is also formed as a surface having a gentle slope. Then, with respect to the locking side connector 40a shown in FIG. 14, the claw member 50 shown in FIG.
When the insertion side connector provided with a is inserted, the locked state as shown in FIG. 15 can be set. FIG. 15
In the example of engagement of both members shown in FIG.
When the insertion side connector 30 is inserted into 0a, the claw member 50a is expanded by the force of the spring 65a. Therefore, the circular arc surface 54a of the claw member 50a is pressed against the circular arc surface 44a of the locking side connector 40a only by the force of the spring,
The claw member is locked between the lower surface of the bolt head and the arcuate surface 44a to exert an action of engaging and holding both members 30, 40a.

When the locking means as shown in FIG. 15 is used, since the claw member is locked only by the force of the spring 65a, a pulling force larger than the force of the spring is applied to both members. When it is applied between the two members, the engaged state of both members can be easily released. Further, in the connecting device of the present invention, a spring as shown in FIG. 10 can be used, and the shape of the pawl spring for urging the pawl member is not particularly limited, and any spring member can be used. Can be used.
