Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention makes it possible to electrically connect electric equipment on the power supply side and electric equipment on the power reception side by absorbing thermal stress, vibration, shock, repulsion of electricity, positional error, etc. between them, or by allowing relative movement between them. It relates to a flexible connecting conductor.

[0002]

[Prior art]

 As shown in FIG. 5, an electrical connection conductor of this type is fitted on both ends of the flexible connection conductor body 1 such as a thin conductor wire, a twisted wire or a bundle of braided wires, and the like. It is composed of terminal parts 2 and 2 for device connection that are fixedly bonded (generally compression bonded), and a cylindrical shield part 3 that surrounds the peripheral surface of the connection conductor body 1 between the connection terminal parts 2 and 2. It is general that In order to prevent the bending of the connecting conductor body from being impaired, the tubular shield component 3 is fixed to the connecting terminal component 2 only at one end thereof. The tubular shield component 3 and the connecting terminal component 2 are fixed to each other by the welding 4 in FIG. 5 or the set screw 5 in FIG.

[0003]

[Problems to be solved by the device]

 However, welding 4 (Fig. 5) between the cylindrical shield part 3 and the connecting terminal part 2 requires a skilled welding operator, and the fixing of the shield part 3 and the connecting terminal part 2 by the set screw 5 (Fig. In 6), since it is necessary to prepare a set screw as a separate component in addition to relatively fine machining such as drilling and internal threading, the structure is complicated and the assembly is time-consuming and costly. There is.

In view of the above-mentioned problems in the conventional electrical connection conductor, the present invention provides a flexible electrical connection conductor that can be structurally assembled easily and can reduce the cost by improving the fixing means of the tubular shield component. The purpose is to do.

[0005]

In order to achieve the above object, the present invention provides a flexible connecting conductor body 1 and a device-to-device connecting terminal component 2 fitted and fixed to both ends of the connecting conductor body 1. In the electrical connection conductor constituted by 2 and the cylindrical shield part 3 provided so as to surround the peripheral surface of the connection conductor body 1 between the connection terminal parts 2 and 2, the shield part 3 One end 3A is compression-bonded to the connection conductor body 1.

[0006]

[Action]

 Since one end 3A of the shield component 3 is compression-bonded 6 to the connection conductor body 1, the connection is easier than conventional welding or screwing. When the connection terminal part 2 is fitted and compression-bonded to the connection conductor body 1, one end 3A of the shield part 3 is sandwiched between the connection terminal part 2 and the connection conductor body 1, so that the connection conductor body 1. The connection terminal component 2 and the shield component 3 are simultaneously joined.

[0007]

【Example】

 1, FIG. 2, FIG. 3, and FIG. 4 each show an embodiment of the present invention, in which reference numeral 1 denotes a flexible connecting conductor body composed of a copper thin wire, a twisted wire, or a bundle of braided wires. . 2 and 2 are terminal parts for connecting to equipment provided at both ends of the connection conductor body 1. The terminal component 2 is a sheath metal made of a conductive material such as copper, and is fitted to both ends of the connection conductor body 1 and fixed by compression processing from the periphery. The above-mentioned terminal parts 2 and 2 are respectively inserted into and fixed in the predetermined connection receptacles of the electric devices on the power supply side and the power reception side.

Reference numeral 3 denotes a cylindrical shield component provided so as to surround the peripheral surface of the connection conductor body 1 between the pair of connection terminal components 2, 2. One end 3A of this shield part 3 is inserted between one of the connecting terminal parts 2 and the connecting conductor body 1, and the connecting terminal part 2 and the connecting terminal part 2 are compression-processed and joined to the connecting conductor body 1.

The shield component 3 shown in FIG. 1 (embodiment 1) is a hard cylindrical one. In FIG. 2 (Example 2), a bellows type shield component 3 is used, and the shield component 3 can be slightly deformed. In FIG. 3 (Example 3), the surface of the connecting conductor body 1 in the portion surrounded by the shield component 3 is covered with the insulating material 7. The wire of the surface portion of the connection conductor body may be broken due to the bending of the connection conductor body 1, but since the wire is covered with the insulating material 7, the broken wire does not go out of the shield component 3. FIG. 4 (Embodiment 4) also has a structure in which a broken wire of the connection conductor body 1 does not go out of the shield component 3, and the shield is provided on the side opposite to the joint side of the shield component 3, that is, on the open side. A coil spring-shaped shield component 8 tightly wound is provided between the end of the component 3 and the connection terminal component 2.

[0010]

[Effect of device]

 According to the present invention, a flexible connecting conductor body, terminal parts for connecting to equipment fitted and fixed to both ends of the connecting conductor body, and a peripheral surface of the connecting conductor body are surrounded between the connecting terminal parts. In the electrical connection conductor composed of the tubular shield part provided on the above, one end of the shield part is compression bonded to the connection conductor body, so that the shield part and the connection conductor body are joined by conventional welding or screwing. It is easier than fixing the shield parts. Also, the structure is simple. Further, since the shield component can be joined at the same time as the joining of the connecting conductor body and the connecting terminal component, there is an effect that the joining work is simplified and the cost is reduced by reducing the number of joining steps.
