DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an F-type connector seat used in combination with an F-type connector plug, and more particularly to an F-type connector seat which can be detached without using screws.

[0002]

2. Description of the Related Art In a television co-listening device, connection between a device and a coaxial cable or between coaxial cables is performed by an F-type connector which is detachable by a screw mechanism. On the other hand, not only coaxial cables but also feeders are used in television accessories, and connectors use a spring mechanism rather than a screw mechanism.
Jack-related connectors are common.

[0003]

As one method of connecting the two in such a situation, it is necessary to provide a new connector that can be adapted to an F-type connector.

[0004] The present invention has been made in view of the above points, and is compatible with an F-type connector plug and can be detached without using a screw mechanism. In addition, the F-type connector can be easily assembled. The purpose is to provide a seat.

[0005]

According to the present invention, there is provided a cylindrical body connected to an outer conductor of a coaxial connector plug, and an insertion portion of an F-shaped plug formed at one end, and another end formed at the other end. A connecting piece for connecting to an external wire is provided, an end of the F-shaped plug where the insertion portion is formed is exposed at one end of the tubular body, and the connecting piece is connected to the other end of the tubular body. An inner element housed in the tubular body so as to protrude therefrom, wherein the tubular body has a hole for engaging with the inner element, and the inner element is connected to the F-shaped plug. A contact pin that is in contact with the center conductor, a claw for engaging with the hole of the cylindrical body, a spacer holder that holds the contact pin at a center position of the internal element, and a protrusion on the outer peripheral surface. And the spacer holder is coaxially fixed to the cylindrical body. A spacer cover, wherein the projection provided on the spacer cover is engaged with the hole provided on the cylindrical main body, and an inner claw provided on the spacer cover is engaged with an outer periphery of the spacer holder. Without screws, which are fixed to each other by engagement of
Shape connector seat.

[0006]

According to the present invention, when a contact pin is inserted into the spacer holder, the contact pin is held at the center of the spacer holder. When the spacer holder in this state is inserted into the spacer cover, the spacer holder is fixed by engaging the outer peripheral portion of the spacer holder with an internal claw provided on the spacer cover. Then, when the spacer cover is inserted into the cylindrical main body, the projection provided on the outer side of the spacer cover engages with the hole provided in the cylindrical main body and is fixed. The contact pins, the spacer holder, the spacer cover and the cylindrical body are fixed to each other only by the insertion operation.

[0007]

As described above, according to the present invention, the contact pin, the spacer holder, the spacer cover and the cylindrical body are mutually fixed only by the insertion operation, so that a connector seat suitable for assembly by an automatic machine is provided. Can be provided
