JPH08242089A - Relay terminal for shielding high frequencies and a high-frequency circuit using the relay terminal - Google Patents

Abstract

PURPOSE: To remarkably lessen high frequencies which are overlaid on a bias line by connecting the bias line to a high-frequency circuit through a relay terminal when a bias is supplied to the high-frequency circuit. CONSTITUTION: A main body of a relay terminal consists of capacitor 2. A terminal for relay 1 to which a bias line can be connected is installed in an upper part of the capacitor 2 and a screw-type screw which can surely be grounded is installed in a lower part of the capacitor 2. Due to this structure, high-frequencies overlaid on the bias line can remarkably be lessened. The relay terminal can be mounted at any places only if they are the ones where screws can be screwed in.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency cutoff relay terminal, and more particularly, to a high-frequency cutoff relay terminal used in a bias circuit in which a high frequency superimposed on a bias line supplied to the high-frequency circuit poses a problem, and the same. It was related to the high frequency circuit.

2. Description of the Related Art In a conventional relay terminal, as shown in FIG. 3, a relay terminal 1 for relaying a bias line and a grounding to GND when fixing the relay terminal 1 to a conductor are used.
It had a structure such that it could be fixed via an insulator or a dielectric 4.

[0003]

This conventional relay terminal is a terminal for relaying a bias line used when supplying a bias to a high frequency circuit, and the relay terminal body is superposed on the bias supply line. There is no effect of cutting the generated high frequency.

In general, a feedthrough capacitor has been used to cut off the high frequency waves thus superposed, but a wall is required because of the structure in order to mount the feedthrough capacitor.

[0005]

In the high frequency cutoff relay terminal of the present invention, the body of the relay terminal is composed of a capacitor, and the lower portion of the capacitor as grounding means is a screw type screw.

[0006]

The present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. The main body of the relay terminal for cutting off the high frequency is composed of a capacitor 2, there is a relay terminal 1 for relaying a bias line on the upper portion of the capacitor 2, and a lower portion of the capacitor 2 is a ground screw 3 for grounding. Made of

In the relay terminal of the present invention, it is possible to attach the relay terminal to the circuit board or the like very easily and surely by using the grounding screw, so that the applicable range is widened.

FIG. 2 is a diagram showing a high-frequency circuit using the relay terminal of FIG. 1, in which a microwave IC (MI
C) 6 is attached, and the bias to this is supplied via the relay terminal 5. Reference numeral 8 is a bias line.

[0009]

As described above, according to the present invention, the main body is the capacitor, so that when the bias line is relayed, it has the effect of significantly attenuating the high frequency wave superimposed on the bias line. Since the screw on the bottom of the capacitor is used, it can be mounted on any surface as long as there is a place where the screw is tightened.
