Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency plug used for receiving a TV broadcast signal or a cable TV signal from a co-listening antenna such as VHF or UHF.

[0002]

2. Description of the Related Art Conventional TV signals and cable TV signals
FIG. 13 shows the structure of a high-frequency plug for joining the V-receiver to a V-receiver via a high-frequency coaxial cable and a wall-mounted receptacle (receptacle). And FIG. 14 will be described.

FIG. 13 schematically shows a plug called a quick connector. In a metallic outer conductor (shell) 20, an insulator 21 is interposed, and a connector pin 22 is provided at the center position of the outer conductor. 20 are arranged coaxially in the longitudinal direction. One end of the connector pin 22 is formed in a bifurcated shape so that the core wire 7 of the high frequency coaxial cable 10 can be sandwiched. Further, the other end of the connector pin 22 is embedded in a wall surface or the like, and is fitted and connected to a TV antenna such as VHF or UHF, or a center conductor of a connector seat connected to a cable cable TV source, and externally. The conductor 20 is also configured to be fitted and connected to the outer conductor of the contact plug by being inscribed or circumscribed.

That is, when the outer conductor 20 is inserted in the direction of arrow A in FIG. 13, it is connected to a connector seat provided on a wall surface (not shown), and the outer conductor 20 holds the braid 9 of the high frequency coaxial cable 10 therebetween. Plug 2 that is integrated with fastener 23
Make up 4.

In the high frequency coaxial cable 10, the jacket 11, the braided wire 9 and the insulator 8 are peeled off to expose the core wire 7, and the core wire 7 is exposed.
Is inserted into the bifurcated portion of the connector pin 22 and is clamped.

In the structure shown in FIG. 14, a flat plate 25 is attached to one end of a connector pin 22 coaxially arranged with the outer conductor 20, and a high frequency coaxial cable 1 is provided via another flat plate 26.
The peeling core wire 7 of 0 is sandwiched and fixed with the screw 27 or the like.

In the configuration of FIGS. 13 and 14, the contact plug 24 and the high-frequency coaxial cable 10 are formed so as to be orthogonal to each other. The high-frequency coaxial cable 10 is inserted when the contact plug 24 is inserted into the connector seat on the wall surface. This is so that the longitudinal direction of the panel and the wall surface or TV receiver panel are parallel to each other.

[0008]

According to the plug described in the above-mentioned conventional structure, both the core wire 7 of the high frequency coaxial cable and the connector pin 22 of the plug 24 are exposed and connected in FIGS. 13 and 14. The electromagnetic field mode at the connection portion is disturbed and the image quality is deteriorated. In particular, since the shielding effect is bad, it is easily affected by an interference radio wave from the outside, and on the contrary, there is a harmful effect that an unnecessary radio wave is emitted to the outside.

Generally, the magnitude of the shield attenuation greatly depends on how to shield the joint between the coaxial cable and the plug and how to connect the core wire of the coaxial cable to the center conductor of the plug or the plug seat. In particular, in a portion where different electromagnetic field modes are coupled as shown in FIGS. 13 and 14, loss is caused by magnetic field coupling as shown in FIG. 15 or radio waves are radiated. Therefore, it is important to match the electromagnetic field modes at the joint between the coaxial conductor 10 and the plug 24.

FIG. 15 shows the core wire 7 of the high frequency coaxial cable 10.
Only the magnetic field component 50 generated between the parallel lines 52 arranged in parallel is shown. Radiated radio waves 51 are generated by such a magnetic field component 50.

The relationship between the shielding attenuation amount and the frequency showing the shielding effect of the conventional plug 24 is only the TV signal because the shielding attenuation amount at a high frequency (UHF) is small as shown by the broken line in FIG. Not only that, it is easily affected by external interference radio waves, and unwanted radio waves are easily emitted from that portion.

Further, there is a problem that the coaxial cable 10 easily comes off from the connector pin 22 of the connector 24 when a force is applied in the direction of pulling out the high frequency coaxial cable 10 in the direction shown by the arrow B in FIGS. 13 and 14.

Further, since the core wire 7 of the coaxial cable 10 is sandwiched between the forked portions of the connector pin 22 or the flat plates 25 and 26, there is a problem that it takes time and effort to connect the coaxial cable 10 and the connector 24. It was

The present invention is intended to provide a high frequency connector which solves the above problems. The object of the present invention is to easily connect the coaxial cable and the connector and to improve the shielding effect. It is designed to obtain a high-frequency plug that is hard to pull out and has no disturbance in characteristic impedance.

[0015]

As shown in FIG. 1, a first high-frequency connector of the present invention has a connector seat fixed to a wall surface or the like and supplied with a high-frequency signal, and this connector. An outer conductor relay member 1 fitted to the outer conductor of the stopper seat and a high-frequency coaxial cable 10 fitted to the outer conductor relay member 1 are provided, and the outer conductor relay member 1 is fitted to the outer conductor of the contact seat. At the same time, the core wire 7 from which the coating of the high-frequency coaxial cable 10 has been peeled off is connected to the inner shaft of the connector seat.

An example of the second high-frequency connector of the present invention is shown in FIG.
As shown in FIG. 6, a connector seat fixed to a wall surface or the like to which a high-frequency signal is supplied, and outer conductors 20a, 20b for relay and relay outer conductors 20a, 20b fitted to the outer conductor and inner conductor of the connector seat. A relay member 33 having internal conductors 22a and 22b,
The relay outer conductors 20a and 20b of the relay member 33 are fitted to the insulating portion 8 of the high-frequency coaxial cable 10, and the relay inner conductors 22a and 22b are fitted to the receiving portion 30 that is fitted to the core wire 7 of the high-frequency coaxial cable 10. It is equipped with.

[0017]

The function of the high frequency connector of the present invention is the connector seat or the relay fitting 33.
Since the core wire 7 of the high-frequency coaxial cable 10 is directly contacted with the inner conductor or the contact receiving portion 30 of the above, it is possible to improve the shielding effect of the connection portion between the coaxial cable and the plug seat 41 or the relay fitting 33. Since the coaxial cable 10 was bent at a right angle and the bulge portion was hooked so as to be inserted between the insulator 8 and the braided wire 9 of the coaxial cable 10, the coaxial cable 10 was pulled in the longitudinal direction. Sometimes, it is difficult to separate at the joint.
