Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coaxial connector used for high frequency coaxial cables.

An antenna rotator is currently used by amateur radio operators and the like. This is essential equipment for directing an antenna with directional characteristics toward an unspecified other party in order to communicate using radio waves.

However, if the antenna rotation machines currently on the market are rotated in the same direction many times, the high-frequency coaxial cable that supplies power to the antenna will be cut off, so to prevent this, the antenna rotation machines are designed to stop after one rotation. It has become.

This is the biggest drawback, even if you want to rotate it an additional 10 degrees after it has stopped, you will not be able to head in the desired direction unless you reverse the rotation and rotate it 350 degrees.

In this way, it can only rotate once, so
This increases unnecessary rotation, which shortens the life of the device, and causes great trouble and inconvenience in adjusting the direction of the antenna.

The present invention was invented to solve these problems.

In order to prevent the high-frequency coaxial cable from getting twisted, it is sufficient to install a rotatable coaxial plug inside the antenna rotator.

FIG. 1 is a sectional view of a rotary coaxial connector and a plan view of an upper connector and a lower connector.

If we explain this for each part, (1) is the center conductor terminal and is connected to (2) by inserting it.

(2) is the center conductor terminal, which has several notches and is connected by pressing (1) inserted using the elasticity of the material.

(3) The outer conductor (4) is a ball bearing that smoothes the rotation of this plug, and connects the upper and lower outer conductors. (5) is an insulator that supports the center conductor terminals (1) and (2). Figure 2 is an example of a configuration diagram of the center conductor terminal (2). (A) is the center conductor terminal (1) In order to strengthen and maintain the pressure on the contact surface, use an insulator such as elastic rubber (6)
Tighten with.

(B) has the same purpose as (A), by providing a groove (7) in any part of the center conductor terminal (2) and attaching a resilient metal fitting or the like to the groove to tighten it.

(C) is mercury (8), which is a metal fitting that is in a liquid state at room temperature.
By enclosing it, the contact surface with the center conductor terminal (1) is enlarged, and since it is liquid, it is noteworthy that there is no abrasion at all.

In the figure, (9) is a vertically cut portion of the center conductor terminal (2), which makes use of the elasticity of the material.

According to conventional conceptual theory, it was common sense that a coaxial connector that could be rotated would be impossible because the connecting parts would wear out, resulting in poor contact and various problems such as noise generation. However, this problem was solved by filling the connection part with mercury as shown in Figure 2 (c).

With the above configuration, the present coaxial connector can be rotated, and becomes a rotary coaxial connector that always maintains a uniform electrical conduction state even when rotated in any left or right direction.

By attaching this rotary coaxial plug to the center of the interior of the antenna rotator, it is possible to rotate the antenna without limit, and it solves all the inconvenience and trouble that would otherwise occur if the antenna only rotates once.
