栓の接続部分で切断する不具合が多発していた。However, some large machines and devices have multiple terminal holes to be inspected, and the connector attached to the measuring device cable must be fitted into each terminal hole of the large number of devices. The work of checking and checking was complicated. In particular, when the connector is a coaxial cable plug or a circular connector for multi-needle cable bundles, both the male and female connectors must be screwed together, and it is cumbersome to do this repeatedly for many devices one by one. Not only that, but as a result of repeated rotations, there were many problems where the measuring instrument side cable was disconnected at the connection part of the plug.

る。That is, like the original connector that is inserted into the terminal hole, the conventional connector is provided with threads all around the circumference that engage with the female screw portion on the inner periphery of the terminal hole. In order to insert the connector into the hole, the connector must be rotated until both threaded portions are completely screwed together, and a similar operation is required to remove the connector. However, since the connector is connected to the measuring device etc. via a cable, it is not easy to rotate it because the cable becomes an obstacle, and the work of attaching and detaching the connector is extremely complicated.As a result, maintenance and inspection work is complicated. As mentioned above, there was a drawback that the cable on the measuring instrument side was disconnected.

The pressing pieces 11, 11 are prevented from coming off from the support hole 10 by inserting a pin 12 into the through hole 11a extending laterally. Further, the other annular portion 9a of the spring 9 is fitted into a groove formed in the inner circumferential surface of the pressing piece 11 to constantly bias it in the outer radial direction.

The cylindrical member 1 is pushed into the terminal hole 20, and when the outer circumferential protrusion of the first cylindrical member 1 abuts against the opening edge of the terminal hole 20, the pressure with the finger is released, and the screw thread 7a and the female screw 21 are released. and can be screwed together. Through such operations, the inspection device is operated with the connector 1 installed in the terminal hole 20 to perform inspections and measurements necessary for maintenance and inspection.

に極めて便利である。In this way, without rotating the connector 1, by simply inserting the connector in the axial direction while pushing in the pressing piece 11, the pressing knob 7, etc., the female screw 21 extending all around the inner wall of the terminal hole 20 can be inserted. Since the screw threads 7a, 7a having short circumferential lengths can be engaged, it is not only easy to attach the connector, but also to remove it easily by pushing the pressing piece 11 etc. and pulling it out. This is extremely convenient for tasks such as inspections where connectors are repeatedly attached and detached.

る。In the above embodiment, the pressing piece 11 and the pressing knob 7 are provided as means for pushing the screw thread 7a, and the pressing piece 1
The configuration is such that the push knob 7 is pushed in after pushing in the button 1, but this is because a two-stage push structure is preferable in consideration of the feel of the hand when pushing in or the operability. Therefore, if one focuses only on the function of pushing in the screw thread 7a and ignores operability, the pressing knob 7 alone is sufficient.

It is convenient for connectors that can be easily attached and detached, since they can be detached immediately after connection and checking are completed. Because the present invention has such convenience, it facilitates the attachment and detachment of inspection connectors to the terminals provided on machines and devices, regardless of their size, and greatly improves maintenance and inspection work efficiency. can do.
