DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coaxial cable connector for connecting a high-frequency electric device to a television outlet installed on a wall or the like via a coaxial cable.

[0002]

2. Description of the Related Art As a coaxial cable connector as described above, a C13 type connector conventionally defined in the EIAJ standard is used for receiving broadcast waves. That is, a TV connection terminal called a TV outlet is provided on a wall surface of a building such as a house, and a coaxial cable is connected between the TV outlet and a high-frequency electric device such as a television receiver or a home video device. And a cable set to which the coaxial cable connector described above is attached for connection to take out a broadcast wave reception signal of a high frequency signal.

[0003] The above coaxial cable connector can be connected to a coaxial cable simply by inserting it into a television outlet. Therefore, the coaxial cable can be easily attached and detached, which is convenient.

[0004]

In recent years, mobile communication devices such as mobile phones have exploded. However, in the above-described conventional technique, the attachment and detachment of the coaxial cable is easy, but the joint of the joint between the coaxial cable connector and the television outlet tends to be relatively loose. Then, from the loosely-coupled portion, a mobile communication radio wave which becomes an interference wave with respect to a signal in a broadcast wave band frequency easily enters. Therefore, it is supposed that a reception obstacle is exerted on a high-frequency electric device or a wiring system for receiving broadcast waves via a coaxial cable.

In order to cope with the above-mentioned reception failure, a television outlet is made to be capable of being screw-joined with a socket for an F-type plug, and this socket is provided with an E-shaped connector as shown in FIG.
C12 type or C15 specified in IAJ standard
It is relatively preferred to employ a coaxial cable connector 100 of the type connector type. However, in this case, since the mounting hole to the television outlet becomes small, it is assumed that the screwing-in F-type connector 101 for the F-type plugging requires time and effort for screwing. Also, as shown in FIG. 3B, the state of the coaxial cable 103 after connection is a state protruding from the wall surface, and the degree of freedom in arranging objects and furniture around the television outlet is limited. You.
By the way, as a countermeasure, a coaxial cable is run substantially parallel to a wall surface using an L-shaped screw-type F-type connector 102 as shown in FIG. However, when connecting to the television outlet having the coaxial cable connector 100 described above, the L-shaped F-type connector 102 is connected to the television outlet as described above because the F-type connector 102 is small. It is assumed that it takes time and effort to make connections.

The present invention has been made in view of the above circumstances, and an object of the present invention is to easily connect to a television outlet having a receptacle for an F-type plug, and to provide a coaxial cable from a wall surface. It is an object of the present invention to provide a coaxial cable connector capable of suppressing the protrusion of the coaxial cable.

It is characterized in that it is connected to bend freely so as to be able to contact and separate from the receptacle.

In this configuration, the F-type plug connection portion of the coaxial cable connector is connected to a television outlet having an F-type plug receptacle installed on a wall or the like, and is electrically connected to the TV socket. The formed coaxial cable connection portion can be bent so that the coaxial cable approaches the television outlet receptacle.

The F-type plug connection portion is inserted into the center of the socket, and has a substantially spherical or substantially cylindrical pivot at its base end, and the contact pin is provided with an insulator interposed therebetween. A connecting body made of a conductive metal to be inserted and connected to the outer periphery of the receptacle, and the coaxial cable connection portion is pivotally connected to the pivot portion at a base end thereof.
It is preferable to have a connection fitting connected to the inner conductor of the coaxial cable. In this case, a substantially spherical or substantially cylindrical pivot at the base end of the contact pin inserted with an insulator interposed in the conductive metal joint body of the F-type plug connection part joined to the outer periphery of the receptacle of the television outlet. The coaxial cable connection part is rotated about the part, and the coaxial cable approaches the television outlet receptacle.

It is preferable that the coaxial cable connecting portion has a sliding body made of a conductive metal, which comes into sliding contact with the joining body, and in which the connecting fitting is inserted with an insulator interposed therebetween.
In this case, the coaxial cable connection portion is bent by sliding the conductive metal sliding contact body portion into which the connection fitting is inserted with an insulator interposed therebetween, with the joining body portion of the F-type plug connection portion.

It is preferable that a protection member having a bellows portion is provided substantially in the middle between the F-type plug connection portion and the coaxial cable connection portion. In this case, the bent portions of the F-type plug connection portion and the coaxial cable connection portion connected to the television outlet are flexibly protected by the bellows portion of the protection member.
