Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector mounting structure for equipment such as a branching device and a distributor used in a CATV system.

[0002]

[Prior art]

 Conventional connector mounting structures for CATV devices include those shown in FIGS. In the connector mounting structure of FIG. 5, the inner end D of the connector C is inserted into the mounting hole B provided in the housing A of the device, and the nut E screwed into the connector C from inside and outside of the housing A is inserted. It is tightened and attached to the same housing A. In the connector mounting structure of FIG. 6, the housing A and the outer conductor F of the connector C are integrally molded, and the center conductor G and the insulating member H are later inserted into the outer conductor F to plug the connector. Is completed. In any case, the printed board K on which electronic parts are attached is screwed to the boss J of the housing A, and the printed board K and the central conductor G of the connector C are soldered to complete. .

[0003]

[Problems to be solved by the device]

 However, in the former case, the contact plug C must be attached to the housing A with a nut, the print board K must be attached to the housing A, and the center conductor G of the contact plug C must be soldered to the printed board K. Therefore, the installation work of the plug C was troublesome. In the latter case, the center conductor G and the insulating member H must be attached to the outer conductor F integrally molded with the housing A, the printed circuit board K is attached, and the center conductor G is soldered. Workability was poor because it had to be done. Moreover, in each case, the workability was particularly poor because the wiring between the central conductor G of the plug C and the printed circuit board K was performed in a narrow space inside the housing.

An object of the present invention is to provide a connector mounting structure for a CATV device in which the connector and the printed circuit board can be easily assembled.

[0005]

[Means for Solving the Problems]

 The connector mounting structure for a CATV device according to the present invention is, as shown in FIG. 1, a structure for mounting a connector 2 on a casing 1 of a CATV device such as a branching device or a distributor, in which a substrate mounting portion is mounted on the connector 2. 3, the printed board 4 is attached to the board mounting portion 3, the cable connector connecting portion 5 of the housing 1 projects to the outside of the housing 1, and the printed board 4 is housed inside the housing 1. It was installed like this.

[0006]

[Action]

 In the connector mounting structure of the CATV device of the present invention, as shown in FIG. 1, after the connector 2 is fixed to the printed circuit board 4 by the substrate mounting part 3, the cable connector connecting part 5 of the connector 2 is mounted on the housing. The CATV device is completed simply by setting the printed circuit board 4 in the housing 1 (main body 8) so as to project to the outside of 1 and covering the main body 8 with the lid 9 as shown in FIG.

[0007]

[Embodiment 1] FIGS. 1 and 2 showing an embodiment of a connector mounting structure for a CATV device according to the present invention, in which 1 is a housing of a device such as a distributor or a branching device used in a CATV system, and 4 is a A printed circuit board 2 in which an electronic circuit housed in the casing 1 is formed is a connector for wiring a coaxial cable to the device, and a total of three connector 2 are attached to the printed circuit board 4. It is attached.

The plug 2 is composed of parts such as an outer conductor 20, a center conductor 21 and an insulator 22 like a normal plug, and is fitted to a connector (not shown) of a coaxial cable. A square plate-shaped plug connector seat 23 is integrally formed on the root side (terminal side) of the outer conductor of the cable connector connecting portion 5. However, as shown in FIG. 2, the connector seat 23 is formed with two board mounting parts 3 for fixing the connector 2 to the printed circuit board 4 in the shape of a bar, and is formed at the tip of each board mounting part 3. The screw 30 of the board 4 is screwed into the screw hole 24 so that the connector 2 can be fixed to the printed board 4. The board mounting portion 3 must be mounted so as to make electrical contact with the ground electrode of the board 5.

The housing 1 is composed of a main body 8 made of an aluminum alloy or a synthetic resin and a lid body 9. Of these, a main body 8 is provided for holding and housing the printed circuit board 4. The substrate housing portion 15 is formed. Further, a U-shaped groove 11 is formed on the edge 10 of the main body 8 and the lid 9, and when the main body 8 and the lid 9 are joined, a circular through hole 17 is formed by the groove 11. Is done. The through holes 17 are provided so as to be at the same positions as the contact plugs 2 attached to the printed circuit board 4, and as many as three contact plugs 2 are provided.

Then, the printed circuit board 4 is fixed to the substrate accommodating portion 15 of the main body 8 by inserting each connector 2 into the groove 11 on the main body 8 side, and finally, as shown in FIG. The device is completed by covering it with.

As shown in FIG. 4, a convex protrusion 26 is formed on the outer circumference of the contact plug seat 23 of the contact plug 2, and a concave groove 27 is formed on the inner circumference of the groove 11 of the main body 8. Then, when the plug 2 is inserted into the groove 11, the plug seat 23 may be directly fixed to the groove 11.

[0012]

[Effect of device]

 The connector mounting structure of the CATV device of the present invention has the following effects. Since the connector 2 is directly attached to the printed circuit board 4, the connector 2 can be mounted on the printed circuit board 4 in the same manner as other electronic components. Assembling the device is completed simply by housing it in the body 1, and as a result, it is possible to reduce the manufacturing process of the CATV device. Since the connector 2 can be directly grounded to the printed circuit board 4 through the board mounting portion 3, the connector 2 and the printed circuit board 4 need to be connected to each other even when the device is used in the device of the housing 1 made of resin such as plastic. Simplifies manufacturing without the need for grounding.
