DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television terminal having a coaxial connector receptacle.

[0002]

2. Description of the Related Art Conventionally, as a television terminal of this type, as shown in FIG. 5, a receptacle 2 for an F-type connector, which is a coaxial connector, is formed at one end of a connector 2 and a coaxial cable 6 is formed at the other end. It is known that a core wire connecting portion 8 having an opening into which the core wire 7 is inserted and connected and a braided wire connecting portion 10 for connecting the braided wire 9 are formed. In the connector 2, the center line of the receptacle 1 and the center line of the core wire connecting portion 8 are formed on a straight line.

[0003]

When the coaxial cable 6 disposed on a wall or the like is connected to the core wire connecting portion 8 and the braided wire connecting portion 10 on the connector 2 described above, the center line of the connector 2 has a wall surface. And is wired along the wall surface to the coaxial cable 6, so that the coaxial cable 6
Is formed with a bent portion. If such a bent portion is formed, there is a possibility that high-frequency transmission characteristics may be degraded, or the core wire or the braided wire of the coaxial cable may be broken. In order to avoid such a problem, it is necessary to increase the depth dimension of the connector 2 in the direction of the center line, and it may not be possible to perform the installation in a limited installation space.

[0004] The present invention has been made in view of the above problems, and the other end of the connector is protruded so as to be narrow in the depth direction.
It is an object of the present invention to provide a television terminal which can be constructed without providing a bent portion of a coaxial cable at a rear portion of the television terminal, which is an installation space provided.

[0010]

In this embodiment, a connector 2 as shown in FIG.
Is exemplified. This connector 2
Has an F-type connector as a coaxial connector at one end.
Is formed, and a screw portion 11 is engraved on an outer periphery of a portion where the receiving port 1 of the F-type plug is provided. At the other end, a core wire connecting portion 8 to which the core wire 7 of the coaxial cable 6 is inserted and connected, and a braided wire connecting portion 10 to which the braided wire 9 is connected are formed in a cylindrical shape. The core wire connection portion 8 and the braided wire connection portion 10 form a connection portion for connecting a coaxial cable. A bent portion is formed between one end and the other end of the connector 2 so that the center line of the receptacle 1 of the F-type plug and the center line of the core wire connecting portion 8 are substantially orthogonal to each other. On the outer peripheral surface of the distal end portion of the braided wire connecting portion 10, a large-diameter portion 15 having a truncated conical shape and formed such that the diameter becomes smaller toward the distal end is integrally formed. A core wire connecting portion 8 which is a hole into which the core wire of the coaxial cable is inserted is bored in the distal end surface of the large diameter portion 15. Core wire connection 8
In order to connect the coaxial cable 6, the core wire 7 is protruded from the end of the coaxial cable 6 as shown in FIG.
And insert the core wire 7 into the core wire connection portion 8 in this state,
The braided wire 9 is put on the braided wire connecting portion 10, and a metal fastener 16 formed in an annular shape is put on the outer periphery of the braided wire 9 put on the braided wire connecting portion 10, and the braided wire 9 is crimped. It is sandwiched between the connection part 10 and the fastener 16.

As shown in FIG. 1B, a synthetic resin molding seat 3 is formed integrally with the connector 2 having the above-mentioned structure around the periphery of the socket 1 of the F-type plug. Here, a concave portion 12 that opens in a circular shape is provided on the front surface of the molding seat 3.
Between receptacles 1 at both ends of connector 2 and braided wire connection portion 10
Is held at the bottom 18 of the recess 12 of the molding seat 3.
And Tsu, receptacle 1 of F-type contact tap at one end of the connector 2 is positioned in the recess 12, the outer periphery of the inner and receptacle 1 part of F-type contact tap of the recess 12 as shown in FIG. 3 The nut 14 provided on the F-type plug 13 provided at the end of the coaxial cable 6 enters into the gap between them. The receptacle 1 of the F-type plug provided on the connector 2 does not project forward from the opening surface of the recess 12.

As shown in FIG. 1A, the molding seat 3 is provided with a mounting portion 5 for mounting on a mounting frame 4 (see FIG. 3) standardized for an embedded wiring device.
As the mounting portion 5, a pair of mounting pieces 5a for mounting on a commercially available mounting frame 4 made of synthetic resin is formed on each side edge. Then, as shown in FIG. 3, the mounting piece 5a is locked and mounted in a locking hole 4b provided opposite to both side pieces 4a of the mounting frame 4 made of synthetic resin. There are provided three sets of locking holes 4b.
Is for three large squares standardized by JIS etc. so that up to three wiring devices of unit size can be mounted, and the mounting seat 3 has a mounting size approximately equal to the wiring device of unit size. In this case, any one of the three sets of locking holes 4b can be used for attachment.
The mounting portion 5 is also provided with a hole 5b in which a mounting claw of a commercially available metal mounting frame is locked, and the hole 5b is used as the mounting portion 5 when mounting on a metal mounting frame. Things.

A bent portion is formed between both ends of the connector 2 so as to make the center line of the coaxial connector 6 and the center line of the core wire connecting portion 8 substantially orthogonal to each other. The coaxial cable 6 and the connector 2 can be connected to each other without forming a bent portion in the coaxial cable 6 even in the limited space of the inside 17. In the above embodiment,
While the connector 2 to form a core wire connection portion 8 and the braided wire connecting portion 10, rather it may also be provided receptacle 1 of F-type contact tap Alternatively, forming between the receptacle 1 at both ends of the connector 2 Of seat 3
It may be configured to be held at the bottom 18 of the recess 12. If the connector 2 having this configuration is used, wiring can be performed using the coaxial cable 6 to which the F-type plug is attached.

According to the above arrangement, when the core wire of the coaxial connector is connected to the core wire connection portion and the braided wire is connected to the braided wire connection portion, the center line of the socket of the coaxial connector and the center line of the coaxial cable intersect. However, even in a limited space, the coaxial cable can be wired without providing a bent portion.

Further, since the coaxial cable is sandwiched between the fastener and the braided wire connecting portion having the large diameter portion, the coaxial cable and the connector can be firmly joined. Also, the coaxial cable can be wired so that no bent portion is formed, and the receiving ends of the coaxial connector are formed at both ends, so that both ends of the connector are both connected to the coaxial cable via the coaxial connector. Can be. That is, by using a coaxial cable to which a coaxial connector is previously connected, the on-site connection work becomes easy.

Further, since it is possible to mount using a mounting frame standardized for wiring equipment, it is possible to divert the mounting frame for wiring equipment, thereby suppressing an increase in manufacturing cost. Further, it can be mounted together with other wiring devices on the three mounting frames.
