Description

The present invention relates to the prevention of disconnection for preventing one connector from being disconnected from the other connector in the connection of a coaxial connector mainly used for a TV joint reception device, and more particularly to the structure of the connector prevention tool. .

Conventionally, a connector for a television joint receiving device has a cable coupling portion connected to a braided conductor of a coaxial cable at the connector plug, and is movable in the axial direction and rotated in the circumferential direction at the base end portion of the cable coupling portion. A ring-shaped engaging portion pivotally attached to the cable connecting portion and the engaging portion; and an elastic member that performs an elastic buffering action between the cable connecting portion and the engaging portion. Provided with a locking piece,
The connector seat is formed with a groove formed by a series of an introduction portion, a guide portion, and a locking portion provided on a screw surface formed on the peripheral surface of the connector seat, and the engagement formed on the connector plug is formed in the groove. Since the stopper is engaged and connected, this coaxial connector plug can be connected to the connector seat only by rotating the ring-shaped engaging portion and can be firmly attached.

In this embodiment, for example, the signal is divided into two and drawn into the lead-in line 32 from the antenna via the distributor 1. In general, the distributor 1 is often installed on an eaves 31 or a ceiling shown in the figure. A conventional construction method in the case of installing in such a place where installation work is difficult to perform is that coaxial cables 33 and 34 in which a connector plug is attached and processed into a predetermined cable length after the distributor 1 or the like is installed on the ceiling or the like. Are connected to the connector seat of the distributor 1, but in the case of ordinary joint reception work, the connector plug and the coaxial F-type connector seat provided in the case 2 in order to increase the connection reliability are: For example, the coaxial cables 31, 32, and 33 are installed at the installation site while facing upward in an unstable state on a stepladder 40 or a scaffold, for example, by using a female screw and a male screw. It was necessary to fix the connector plug to the connector seat with a wrench or the like after fixing it to the mounting surface by a well-known method such as a clamp after fitting it to the shape, which was dangerous and poor workability.

Therefore, for simplification of work, for example, if the coaxial cable is fixed in advance on a floor surface that is easy to perform construction, when the distributor 1 is lifted to the ceiling or the like, the distributor 1 is turned upside down and the mounting surface is placed under the eaves. It is necessary to face the installation surface.
