Abstract

PURPOSE:To prevent air from being left between a socket and a plug to prevent electric discharge by automatically supplying the insulating oil in a housing between the socket and plug. CONSTITUTION:A high-tension cable 14a plug 14 is inserted into the socket 1 of a housing 17, and electrically and mechanically connected thereto. When the cable plug 14 is inserted into the deep part of the socket 1, a movable terminal 9 is pushed down by each plug contact 13. When the movable terminal 9 is pushed to the end, an O-ring 10 passes through a through-hole 21, and the insulating oil 8 in the housing is automatically supplied to the inner part of each socket contact 2 through this through-hole. The supplied insulating oil 8a is supplied between the socket contact 2 and the plug contact 13 and further to the clearance between the plug 14 and the socket 1. When it is filled with the insulating oil, the flange part 14b of the plug 14 is fastened and fixed to the plug receiving part 17a of the housing 17 by an insulating oil leakage preventing packing and ring nut.

Embodiments will be described below with reference to the drawings. The same parts are denoted by the same symbols. In the embodiment of the present invention, as shown in FIGS. 1 to 3, a cylindrical socket 1 made of an insulator having a bottom is provided in a housing 17 which accommodates an X-ray tube (not shown) therein, and the insulating oil 8 in the housing is prevented from leaking. It is fixed by an O-ring 20 and a ring nut 19 for preventing leakage of insulating oil supplied from the housing through the O-ring 18. On the X-ray tube side of the socket 1, a pair of socket contacts 2 is an O-ring 3 for preventing leakage of insulating oil in the housing, a desk 4 holding this O-ring, and a washer 5
It is fixed by a nut 6 through. Therefore, a through hole 21 that serves as a supply path for the insulating oil 8 in the housing is formed at a predetermined position of each socket contact 2 at the tip of the socket contact 2. A movable terminal 9 is fitted and provided at the tip of each socket contact 2. An O-ring 10 for preventing leakage of insulating oil in the housing is fixed by a ring nut 11 to the collar portion 9a of the movable terminal 9 that contacts the outer peripheral surface of the socket contactor 2. In order to bring the movable terminal 9 and the socket contactor 2 into contact with each other, a spring 12 having an elastic action in the contracting direction is arranged between the ring nut 11 and the nut 6.

As shown in FIG. 1, the socket 1 of the housing
The plug 14 of the high-voltage cable 14a is inserted into the inside of the plug to electrically and mechanically connect the plug. When the cable plug 14 is inserted all the way into the socket 1, the movable terminals 9 are pushed downward by the plug contacts 13 as shown in FIG. When the movable terminal 9 is pushed to the end, the O-ring 10 passes through the through hole 21, and the insulating oil 8 in the housing is automatically supplied to the inside of each socket contact 2 through the through hole. The supplied insulating oil 8a is supplied from between the socket contactor 2 and the plug contactor 13 to the plug 14 and the socket 1.
Is supplied in the gap between. After the entire gap between the plug 14 and the socket 1 is filled with insulating oil, the flange portion 14b of the plug 14 is plugged into the housing 17 with insulating oil leakage prevention packing and a ring nut (neither is shown). It is fastened and fixed to the receiving portion 17a. As a result, the insulating oil 8a supplied to the gap between the plug 14 and the socket 1 does not leak outside the X-ray tube device.

Since the insulating oil is a liquid unlike silicon grease, it is uniformly supplied to the gap between the plug 14 and the socket 1. When the high voltage cable plug is pulled out from the socket of the housing, the O-ring 10 shuts off the through hole 21 of each socket contactor 2 and its inside from the insulating oil in the housing due to the elastic action of the spring 12. , It can be done without leaking the insulating oil. In this way, it can be attached and detached.
