Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coaxial connector used in communication equipment and the like, and particularly to a T-shaped coaxial connector in which the fitting direction of the coaxial connector and the pulling direction of the coaxial cable are formed at right angles.

A T-type coaxial connector is composed of a connector terminal part to which the outer conductors of two opposing coaxial cables are connected, and a connector body part for drawing out a third coaxial system from this terminal part. Two cylindrical functional parts are combined and integrated into a T-shape.

In a conventional T-type coaxial connector, the connector main body is formed of a first cylindrical conductor, and the connector terminal portion is formed on the outer peripheral surface of the cylindrical conductor.
The second cylindrical conductors are joined by brazing or the like, and the whole has a T-shape.

With coaxial connectors of this conventional structure, there is no problem in connecting the outer conductors to each other when connecting coaxial cables, but it is difficult to connect the center conductors to each other, and as devices become smaller and more dense, coaxial connectors With the trend toward miniaturization and smaller diameters, problems arise, such as the need for skilled workers to handle some connector structures.Especially when connection work is performed by soldering, etc., it is important to thoroughly check after soldering. The drawback is that it cannot be done.

FIG. 1 is a perspective view showing the structure of a conventional T-shaped coaxial connector. In the figure, reference numeral 1 denotes a connector terminal outer cylinder, which is formed into a beak shape following the radius of the connector main body outer cylinder 2, and is integrally joined to the connector main body outer cylinder 2 by, for example, brazing. forming a shape. 3 is a hole for inspecting the soldering work of the center conductor of the coaxial cable, and 4 is a cap that is sealed for the purpose of electrical shielding after soldering is completed.

FIG. 2 is a sectional view showing how a coaxial cable is connected to the conventional T-shaped coaxial connector shown in FIG. 1.
In the figure, 5 indicates the center conductor of the coaxial connector, and 6 indicates the dielectric insulator. Reference numeral 8 designates the center conductor of the coaxial cable, which is engaged with a groove 5a (see FIG. 1) provided at the end of the connection portion of the center conductor 5 of the coaxial connector, and is connected and fixed by soldering. 9 is an insulator of the coaxial cable, 10 is an outer conductor braided wire of the coaxial cable, and this braided wire is placed over the outer periphery of the connector terminal outer cylinder 1.
Furthermore, the braided wire 10 and the connector terminal outer cylinder 1 are mechanically connected by a crimp ring 7 from the outside of the braided wire 10.

An object of the present invention is to provide a T-shaped coaxial connector that eliminates the above-mentioned drawbacks, has excellent workability, and can be thoroughly inspected even after soldering work is completed.

Describing the structure of the present invention, the present invention consists of 2
In order to connect two coaxial cables in a straight line by butting their ends together, a connector terminal section is provided, which is made up of two terminal connecting parts to which the respective terminals of the two coaxial cables are connected and are in a straight line; In a T-type coaxial connector in which a connector main body for drawing out a third coaxial system from a butt joint is connected in a right angle direction, a cylindrical body is connected between the two terminal joints to be butt-joined in the connector terminal part. A connector main body having a connector center conductor therein is coupled and connected to a hole bored in one place on the outer circumferential surface of the cylindrical body, and an outer circumferential This is a T-shaped coaxial connector that is provided with a notched window hole that covers approximately half of the surface and a cover covering the window hole.

Hereinafter, the present invention will be explained by way of examples with reference to the drawings.

FIG. 3 is a perspective view showing an embodiment of the present invention. In the figure, 11 is a connector terminal outer cylinder;
Reference numeral 2 indicates a cylindrical body portion that connects the terminal outer cylinders 11, 11, and 13 indicates an outer cylinder of the connector main body.
The outer circumferential surface of the connector terminal outer cylinder 11 has a predetermined length of unevenness for crimping connection of the coaxial cable braided wire, and the central cylindrical body has a connector main body outer cylinder 13 and a groove. A hole for joining is formed. Further, on the upper surface of this joining hole, a window hole 14 is provided by cutting out approximately half of the outer peripheral surface of the cylindrical body portion 12 for soldering work of the center conductor. The connector main body outer cylinder 13 is formed into a beak shape following the radius of the outer peripheral surface of the cylindrical body part 12, and is integrally connected to the cylindrical body part 12 by joining by brazing or the like. 15
1 is a shielding cover after the soldering work is completed, and is usually formed of a metal plate having conductivity and elasticity, and is detachably engaged with the upper part of the cutout window hole 14.

FIG. 4 is a sectional view showing how this embodiment is connected to a coaxial cable.

As is clear from FIGS. 3 and 4, a window hole 14 cut out approximately halfway around the outer circumferential surface of the cylindrical body portion 12 is provided as a hole for soldering work, making it possible to perform soldering work in a wide space. As a result, the degree of freedom of the soldering iron tip can be increased to 180°, greatly improving work efficiency. Similarly, soldering can be confirmed from a wide field of view during inspection after soldering work.

As is clear from the above description, according to the present invention, the connection between the connector main body outer cylinder and the connector terminal outer cylinder is reversed compared to the conventional structure, and the connector terminal side outer cylinder is used for soldering work. By providing a window hole, the workability of the coaxial cable center conductor connection work can be significantly improved, and the connection quality of soldering work etc. can be checked extremely easily and reliably, thereby improving the connection reliability of the coaxial connector. It has the effect of being able to improve the
