Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coaxial connector used in communication equipment and the like, and particularly to an L-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.

An L-type coaxial connector consists of a connector main body that has a mating part that mates with a mating coaxial connector, and a connector terminal to which the outer conductor of the coaxial cable is connected, and these two cylindrical functional parts are joined into an L-shape and integrated.

In a conventional L-shaped coaxial connector, the connector main body is formed of a first cylindrical conductor, and a second cylindrical conductor forming a connector terminal portion is formed on the circumferential surface of one end side of the cylindrical conductor. They are joined together by attaching, etc., and are L-shaped as a whole.

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 Coupled with miniaturization and the trend toward miniaturization, problems arise, such as the need for skilled workers to handle some connector structures, and in particular, when connection work is performed by soldering, etc., sufficient confirmation after soldering is required. The drawback is that it cannot be done.

FIG. 1 is a perspective view showing the structure of a conventional L-shaped coaxial connector.

In the figure, reference numeral 1 is a connector terminal outer cylinder, and the end on the joining side with the connector main body outer cylinder 2 is formed into a beak shape following the radius of the connector main body outer cylinder 2, and is, for example, soldered. It is integrally joined to the outer cylinder 2 of the connector main body part by means of the above-mentioned means to form an L-shape. Reference numeral 3 is a hole for soldering and inspection of the coaxial cable center conductor, and numeral 4 is a cap that is sealed for the purpose of electrical shielding after soldering.

FIG. 2 is a sectional view showing how a coaxial cable is connected to the conventional L-shaped coaxial connector shown in FIG.
In the figure, reference numeral 5 indicates the center conductor of the coaxial connector, and reference numeral 6 indicates the dielectric sag. Further, the same numeral 8 is the center conductor of the coaxial cable, which is engaged with a groove 5a (see FIG. 1) provided at the end of the connecting portion of the center conductor 5 of the coaxial connector, and is connected and fixed by soldering. The numeral 9 is the insulator of the coaxial cable, and the numeral 10 is the outer conductor braided wire of the coaxial cable. Braided wire by crimp ring 7,
10 and the connector terminal outer cylinder 1 are mechanically connected.

As is clear from FIGS. 1 and 2, in the conventional L-shaped coaxial connector, the L-shaped coaxial connector in the coaxial cable is formed by soldering or the like between the coaxial cable center conductor 8 and the coaxial connector center conductor 5. The connection work must be carried out in a narrow space, resulting in poor work efficiency and requiring a high level of skill on the part of the operator.In addition, inspection after the soldering work is completed can only be carried out from a narrow viewing angle from above the soldering hole 3. There are quality problems such as:

The object of the present invention is to provide an L-shaped coaxial connector that eliminates the above-mentioned drawbacks, has excellent workability, and allows sufficient inspection even after soldering work is completed.

The connector of the present invention has a connector main body which has a mating part with a mating connector at one end and a connector center conductor inside, and a connector terminal part which has a coaxial cable connection part at one end and are connected in a right angle direction. In the L-shaped coaxial connector, a connection hole is provided in a predetermined part around the other end of the terminal part and is connected to the other end of the main body part, and a notched window hole for terminal construction provided in a predetermined portion of the periphery; an end face hole provided in the end face of the other end of the terminal portion; a removable cover attached to cover the notched window hole; It is equipped with a removable cap that is attached to cover the end hole.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 3 is a perspective view showing an embodiment of the present invention. In the figure, reference numeral 11 indicates a connector terminal outer cylinder, and reference numeral 12 indicates a connector main body outer cylinder. On the outer peripheral surface of one end of the connector terminal outer cylinder 11, there is a connecting part 32 having an unevenness for connecting the coaxial cable braided wire by crimp over a predetermined length, and on the other end, there is a connecting part 32 for joining the connector main body outer cylinder 12. A connection hole 31 is formed. Further, a window hole 13 is provided on the upper surface of the connection hole 31 by cutting out approximately half of the outer circumference of the connector terminal outer cylinder 11 for use in soldering the center conductor. Connection hole 3 of connector main body outer cylinder 12
One end is formed into a beak shape following the radius of the joint of the terminal outer cylinder 11, and is joined by brazing or the like to be integrated with the terminal outer cylinder 11. Further, a fitting portion 30 for fitting with a mating coaxial connector is formed at the other end. Reference numeral 21 is a shielding cover after the soldering work is completed, and is usually formed of a metal plate having conductivity and elasticity, and has a semi-cylindrical shape with a radius slightly smaller than the joint radius of the terminal outer cylinder 11. The notched window hole 13 is externally fixed to the upper part of the notched window hole 13 in a manner that allows it to be freely attached and detached. Reference number 14 is the terminal outer cylinder 11
It is a cap that seals the end hole 22 of the terminal part outer cylinder 1 by screwing, for example, after inspecting the window hole 13 and the end hole 22 after soldering the center conductor.
It is removably internally locked at one end.

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 1 is cut out approximately half the circumference of the connector terminal outer cylinder 11.
Since 3 is provided as a hole for soldering work, it is possible to perform soldering work in a wide space, and the degree of freedom of the soldering iron tip is also obtained over 180 degrees, greatly improving work efficiency. Similarly, regarding inspection after soldering work, not only can soldering be confirmed from a wide viewing angle, but also confirmation can be made from the end face hole 22.

As is clear from the above explanation, the present invention includes:
The connection between the outer cylinder of the connector main body and the outer cylinder of the connector terminal part is reversed compared to the conventional structure, and a window hole for soldering work is provided in the outer cylinder of the connector terminal side, thereby improving the workability of connecting the center conductor of the coaxial cable. Furthermore, the quality of connections such as soldering work can be checked extremely easily and reliably, which has the effect of improving the connection reliability of coaxial connectors.

Note that the L-shaped connector having the structure of the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, the shielding cover 21 can be replaced with
It can also be inserted and locked from the end hole 22 of the.
