Description

  The present invention relates to a coaxial connector seat unit, and more particularly, to a universal coaxial connector seat unit that can be attached to a casing of a signal distributor / branch and can take any angle in order to easily perform the operation of connecting a coaxial connector. .

  For example, in a signal distributor and a signal branching device, a large number of coaxial cables are connected using a coaxial connector. On the other hand, the signal distributor and the signal branching device are required to be miniaturized because they are incorporated in, for example, one corner of the switchboard. A large number of connector receivers are provided on the outer surface of the housing, and it is usual to force a work in a narrow space between the connector receivers when connecting the coaxial connectors.

In view of this, there has been provided a device that attempts to secure a work space by rotating a plug seat for connecting a coaxial cable in a signal distributor (see Patent Document 1).
JP 2004-247228 A

  However, since the coaxial cable is quite rigid and requires a force for routing, the axis of the coaxial cable drawn in from various directions and the axis of the plug seat of the signal distributor are oriented in different directions. The connection work is difficult and the work time becomes long.

  The present invention has been made in consideration of the above-described points, and an object of the present invention is to provide a signal distributor and a branching device that can change the orientation of the plug seat as freely as possible.

In order to achieve the above object, in the present invention,
In the coaxial connector seat attached to the signal distributor / branch case,
A receptacle seat having a L-shaped side surface and a connection port at the tip;
