[0002]

2. Description of the Related Art Conventionally, in communication equipment and CATV equipment, each circuit is housed in a rack, and a panel for each circuit is provided on the front of the rack. In such a device, when connecting each circuit, a coaxial plug provided at one end of the coaxial cable is connected to a coaxial connector provided on the panel, and provided on the other side of the coaxial cable. The connected coaxial plug is connected to a coaxial connector provided on a panel of a circuit to be connected. In this case, when the two coaxial connectors to be connected are disposed close to each other, the coaxial cable is bent and connected in a U-shape. However, when the coaxial cable is bent in a U-shape in this manner, the high frequency characteristics are reduced. Deterioration sometimes occurred.

Therefore, as an alternative, an L-shaped coaxial connector plug has been used to arrange the coaxial cable substantially along the panel. The L-shaped coaxial connector plug has a connector portion at one end and a plug portion at the other end, and has an L-shaped overall shape. For this reason, in the L-shaped coaxial connector plug, it is necessary that the center conductor in the plug portion and the center contact in the connector portion be arranged orthogonally inside the main body, and the center conductor and the center contact in the L-shaped coaxial connector plug are connected. The connection work becomes complicated, and the configuration of the L-shaped coaxial connector plug itself becomes complicated.

[0004]

In order to solve this problem, the applicant of the present invention has proposed a method disclosed in Japanese Patent Application No. 2000-117545.
Type coaxial connector plug is proposed. FIG. 11 shows a configuration example of the L-shaped coaxial connector plug. The L-shaped coaxial connector plug 100 shown in this figure has a configuration in which a rotation mounting body 121 in a plug portion is rotatable with respect to one end of a main body 102 formed in an L shape, and can be screwed to another coaxial connector. It has been. That is, at one end of the main body 102, a rotary mounting body 121 having a polygonal shape such as a hexagon or a knurling process on the outer circumferential surface and a thread portion formed on the inner circumferential surface is fixedly attached to one end of the main body 102. ing.

Due to the frictional force between the tip of the
The L-type coaxial connector plug 100 cannot rotate with respect to the coaxial connector. Therefore, when a stress is generated in the coaxial cable connected to the connector portion due to a twist or the like, the stress remains applied to the coaxial cable, which has an adverse effect on the coaxial cable, the L-type coaxial connector plug 100 or the coaxial cable. There has been a problem that the connector may be damaged or loose. Also, if the plug portion of the L-shaped coaxial connector plug 100 becomes loose, the connection of the ground to the coaxial connector becomes incomplete, the insertion loss characteristics and the reflection loss characteristics of the L-shaped coaxial connector plug 100 are deteriorated, and signal transmission / reception is deteriorated. The problem of hindrance arises.

Accordingly, an object of the present invention is to provide an L-shaped rotary coaxial connector plug in which the connector can rotate relative to the plug in the mounted state.

Since the ring-shaped spring housed in the rotary mounting body can make a reliable ground connection, the electrical characteristics of the L-type rotary coaxial connector plug do not deteriorate.

When the second ring-shaped spring is housed on the front side in the rotary mounting body, the ground connection can be made using the two ring-shaped springs, and even if the main body is loosened, the ground connection is not incomplete. You can do so. Furthermore, since the total length of the rotary mounting body that houses the two ring-shaped springs is long, the rotary mounting body can be easily operated with fingers, and the L-type rotary coaxial plug can be easily attached to the embedded coaxial connector.

As described above, in the L-type rotary coaxial connector plug 1 according to the present invention, the connection between the center conductor 22 and the center contact 13 which are arranged substantially orthogonally can be performed by a simple operation.

Next, the rotary mount 21 is mounted on the fitting cylindrical portion 2d formed on the outer periphery of the plug storage chamber 2a in the connector plug main body 2.
1 has a hexagonal shape like a hexagonal nut, and is made of metal. As shown in FIG. 7B, the rotation mounting body 21 has a mounting screw portion 21c that is screwed to the coaxial connector at a substantially central portion of the inner peripheral surface of the rotation mounting body 21. A first spring storage portion 21a in which a first ring-shaped spring 24 is stored is provided at a front portion of the inner peripheral surface of the rotary mounting body 21.

As shown in FIG. This configuration,
The coaxial plug 1 according to the embodiment of the present invention has a characteristic configuration.

Thus, when the rotary mounting body 21 is screwed to the coaxial connector 50 and is fixed so as not to rotate, the connector plug main body 2 is rotatable with respect to the rotary mounting body 21 due to the presence of the above-mentioned gap. Therefore, the connector plug main body 2 is rotatable with respect to the coaxial connector 50. That is, when the coaxial cable is connected to the connector portion 10 and the coaxial cable is twisted or the like and a stress is applied, the coaxial cable rotates together with the connector plug body 2 to remove the stress. .

As described above, when the L-shaped rotary coaxial connector plug 1 is screwed into the coaxial connector 50, the coaxial connector 5
Even if there is a gap between the front end surface of the connector plug 0 and the curled portion 2c, the electrical connection between the connector plug main body 2 and the rotary mounting body 21 is performed by the second ring-shaped spring 25 interposed therebetween. Become like As a result, the ground connection via the shell of the coaxial connector 50, the rotary mounting body 21 and the connector plug main body 2 is reliably performed. The second ring-shaped spring 25 is
Since it is housed in the groove formed by the second locking projection 21g, it is not crushed until it becomes flat, so that the spring action is not lost.

When the L-type rotary coaxial connector plug 1 is mounted on the coaxial connector 50 as shown in FIGS. 3 and 4, the rotary mount 21 is rotated and the rotary mount 2 is rotated.
This is performed by screwing the first mounting screw portion 21c to a male screw formed on the outer peripheral surface of the coaxial connector 50. In this case, since the length of the rotary mounting body 21 is long,
Even if the coaxial connector 50 is provided so as to be embedded in a wall or the like, the rotary mounting body 21 can be securely grasped with a finger and screwed easily. When the L-shaped rotary coaxial connector plug 1 is attached to the coaxial connector 50, the rotary mount 21 and the coaxial connector 50 are also electrically connected by the first ring-shaped spring 24 housed in the rotary mount 21. become.

Thus, even if the rotary mounting body 21 is loosened with respect to the coaxial connector 50 for some reason, the coaxial connector 50 and the connector plug main body 2 are connected by the coaxial connector 50 -the first ring-shaped spring 24 -the rotary mounting body. 2
1-the second ring-shaped spring 25-the connector plug body 2 is reliably connected by the route. Therefore, even if the L-type rotary coaxial connector plug 1 is loosened, the insertion loss characteristics and the return loss characteristics can be improved over a wide band. Since the first ring-shaped spring 24 is also housed in the groove formed by the first locking projection 21f, it is not crushed until it becomes flat, so that the spring action is not lost. ing.
