A plurality of tapered guide rods having different diameters are erected in one of the connector modules, and a guide hole is formed in the other connector module so as to fit into each of the guide rods. Is fixed upward on the upper surface of the device, a handle for remote operation is provided on the upper connector module, and the connection cables of each connector unit of the upper connector module are bundled together, and the connector modules are connected to each other by the weight of the upper connector module. Is a remote attachment / detachment connector device to be connected.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS For example, two guide rods having different diameters are erected on a lower connector module,
Preferably, a plurality of female connector units are provided, a guide hole having a corresponding hole diameter is formed in the upper connector module, and a plurality of male connector units are provided. The guide rod may vary in length with diameter. The male connector unit may be provided in the lower connector module, and the female connector unit may be provided in the upper connector module. Further, the guide hole may be provided in the lower connector module, and the guide rod may be provided in the upper connector module. Alternatively, one guide rod may be provided in the upper connector module, and the other guide rod may be provided in the lower connector module.

[0007]

1 is an explanatory view showing an embodiment of a remote detachable connector device according to the present invention, and FIGS. 2A and 2B are explanatory views of a connection surface of both connector modules. This remote attachable / detachable connector device 10 is used for equipment 1 in a hot cell.
2 comprises a combination of a lower connector module 14 attached upwardly to the upper surface of the second connector module 2 and an upper connector module 16 placed thereon.

A plurality of (five in FIG. 2) female connector units 20 are provided in the lower connector module 14, and two female connectors having different diameters and different lengths such as a large diameter and a small diameter are provided on both sides of the upper surface. Guide rods 22a, 22b
Is established. Each female connector unit 20 has a structure in which a large number of contact holes 24 are regularly arranged. Wiring (not shown) with equipment in the hot cell is connected to the contact portion of each contact hole 24. You. Each of the guide rods 22a and 22b has a tapered tip, and has a structure that can be easily inserted into a guide hole described later.

On the lower surface of the upper connector module 16,
The male connector unit 30 is disposed at a position corresponding to the female connector unit 20, and guide holes 32a and 32b having different lengths of a large diameter and a small diameter so as to fit into the two guide rods 22a and 22b. Form. Each male connector unit 30 has a structure in which contact pins 34 that are fitted into the contact holes 24 are regularly arranged. Each core wire of the connection cable 36 is connected to the base end of each contact pin 34, and each connection cable 36 is bundled and pulled out. A handle 40 for remote operation is attached to the upper part of the upper connector module 16.

[0010] The lower connector module 14 is fixed upward to the upper surface of the equipment 12 in the hot cell. The connection method of the remote attach / detach connector device is as follows. A grip 40 of the upper connector module 16 is grasped by a remote operation device 42 such as a manipulator with respect to the lower connector module 14 fixed to the equipment 12 in the hot cell, and a guide of the upper connector module 16 is provided. The holes 32a and 32b are moved near the guide rods 22a and 22b of the lower connector module 14 to be positioned and covered so as to be inserted along the guide rods 22a and 22b. Then, the upper connector module 16 is lowered by its own weight, and the corresponding male connector unit 30 and female connector unit 20 are connected to each other (each contact pin 34 is connected to the contact hole 2).
4), and the connection state of the upper connector module 16 is ensured by its own weight. In this way, many connector units are connected at once.
The disconnection is completed only by grasping the handle 40 with the remote control device 42 and pulling up the upper connector module 16.

The provision of the handle 40 for remote control on the upper connector module 16 allows the remote control device 42 such as a manipulator to easily connect and disconnect the remote detachable connector device 10. By the weight of the upper connector module 16, the connection between the male connector unit 30 and the female connector unit 20 is achieved, and the connection state can be stably maintained. Since a large number of connection cables 36 connected to each male connector unit 16 are bundled together, so-called "roughness" of the cables can be eliminated, and the routing of the cables is organized and the handling is easy. . Since the two guide rods 22a and 22b have different diameters and lengths, the directions in which the upper connector module 16 and the lower connector module 14 can be connected are limited, and even if the arrangement of the connector units is symmetric, they are in the wrong direction. There is no connection. Also, the guide rods 22a, 22
Since 2b has a tapered distal end, the positioning operation of the upper connector module 16 by the remote control device 42 can be smoothly performed with a wide allowable range.

[0012]

According to the present invention, a power supply to equipment installed in a hot cell can be provided because a dozen or more cables are bundled into one and can be detached at a time by a remote control device without making a mistake in the direction. -It is possible to connect and disconnect signals easily and efficiently. Further, since the connection is fixed by the weight of the upper connector module, there is no loosening, and the reliability of the connection can be secured.
