Abstract

PURPOSE: An air line guide tool is provided to improve the convenience and the mounting accuracy of an air line which is hard to attach or detach by preventing the damage of an inner conductor. CONSTITUTION: An air line guide tool comprises a guide member. The guide member is composed of plastic material and formed in the shape of a tube. The guide member guides an inner conductor (140) of the air line to be coupled to the inner conductor of a measurement port via an inner tube by being inserted at an outer conductor (110) of the air line in the inserting direction of the inner conductor of the air line. The guide member forms a length to be longer than the length of the air line.

Description

Airline guide tool {GUIDE TOOLS FOR AIR LINE}

TECHNICAL FIELD The present invention relates to an air line guide tool, and more particularly , to an air line guide tool used for detaching an air line inner conductor and adjusting and checking concentricity of an inner conductor.

The network analyzer is the most important and widely used measuring instrument for evaluating the characteristics of microwave equipment used in various fields such as communication, defense, and aviation. For accurate calibration of this equipment, air lines of various lengths or thicknesses are used as references. That is, the physical size (length, thickness) of the airline determines the resonance frequency and the characteristic impedance by the airline, so products of various lengths and thicknesses are sold and time domain measurements are performed. It is also utilized.

 With the recent development of electromagnetic wave related technologies, the frequency of electromagnetic waves used in systems such as communication and transportation has increased, and the frequency bands of various measuring equipment used for electromagnetic wave measurement have also increased. For example, a measuring instrument capable of measuring up to 18 GHz uses a coaxial connector with an outer diameter of 7 mm, but an instrument measuring up to 67 GHz uses a coaxial connector with an outer diameter of 1.85 mm. Lines, etc., shall have connectors of the same standard. The use of connectors with very small dimensions makes it more difficult to install airlines with separate inner and outer conductors. Not only beginners but also people who are good at using airlines are likely to leave irreparable damage to their precision equipment, the airline. An airline is an expensive tool, and if the inner conductor is bent due to careless handling or the inner surface of the outer conductor is scratched by a metal body, the electromagnetic wave transmission characteristics of the airline are changed, and the air line can no longer function as a reference machine.

3 is a coupling diagram of a general air line. Referring to FIG. 3, the air line and the measurement port are normally coupled. Referring to the process of combining the air line and the measurement port, first, when the female connector 130 of the air line is connected to the male connector 220 of the measurement port, Naturally, the outer conductor 110 of the airline is connected to the measurement port outer conductor 210 so that the measurement reference plane 112 of the airline and the measurement reference plane 211 of the measurement port come into close contact with each other. Thereafter, the inner conductor 140 must be coupled to the inner conductor 230 of the measurement port through the process of inserting the inner conductor 140 into the outer conductor of the airline. However, when the inner conductor of the airline is inserted in this manner, damage may occur due to contact with the outer conductor, and the concentricity of the inner conductor having been inserted has a large error.

In addition, the male connector 120 of the airline should be equipped with another measuring port or a reflection standard. If the coupling of the inserted inner conductor 140 is not complete or the concentricity is not fitted, the airline and measurement The problem is that the port is permanently damaged.

The technical problem to be achieved by the present invention is to provide an airline guide tool that can increase the ease of use of the airline difficult to install / detach according to the miniaturization of the connector standard and the mounting precision.

According to an aspect of the present invention, an air line guide tool for guiding an air line having one end connected to a measuring port of a network analyzer, wherein the air is inserted in a direction in which the inner conductor of the air line is inserted in the form of a tube; Provided is an airline guide tool including a guide member inserted into an outer conductor of a line to guide the inner conductor of the airline to the inner conductor of the measuring port through an inner tube.

The guide member may be made of plastic.

The length of the guide member may be formed longer than the length of the air line.

One end of the guide member inserted into the outer conductor of the air line and contacting the measuring port may be chamfered.

The diameter of the other end of the guide member protruding to the outside of the air line is formed larger than the diameter of the air line outer conductor may have a constant step.

At least one slot structure may be formed at the other end of the guide member.

And a length adjusting member mounted between the other end of the air line and the other end of the guide member and supporting the other end of the air line and the other end of the guide member to adjust the insertion length of the guide member.

It may be configured to further include an extension member mounted to the other end of the air line to support the outer circumferential surface of the guide member, to prevent flow when the guide member is detached.

Fitted to the outer conductor of the airline, it may further comprise an alignment member capable of checking the concentricity between the inner conductor and the outer conductor of the airline through the inner conductor hole in a hollow cylindrical shape.

The alignment member may align the inner conductor and the outer conductor of the airline within the diameter range of the inner conductor hole.

Airline guide tool of the present invention can increase the ease of use and mounting accuracy of the airline is difficult to install / detach according to the miniaturization of the connector standard.
