Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for connecting a CATV device such as an amplifier, a distributor, and a branching device to a housing and mounting a substrate.

[0002]

[Prior Art]

 There are various types of CATV equipment, but basically, a die-cast aluminum housing is provided with a plug, and a board on which an electronic circuit is formed is built in the housing. When the electronic circuit uses a high frequency above the UHF band, as shown in FIG. 4, the earth mounting bracket D is integrally formed with the outer conductor C of the connector B attached to the housing A. The board E is screwed to the fitting D so that the connector B and the ground electrode of the board E can be grounded to the housing A.

[0003]

[Problems to be solved by the device]

 However, the structure of FIG. 4 has the following problems. Since the plug B and the ground mounting bracket D are integrated, the mounting position of the board E (especially the upper and lower positions) is limited to the mounting position of the plug B. For this reason, conventionally, the board E and the housing A must be designed for each movement according to the mounting positions of the base plate E and the connector B, and when changing the mounting positions thereof, It is troublesome to redesign each time. Since the plug B and the earth mounting bracket D are integrated, the load of the board E applied to the mounting bracket D is applied to the plug B as it is, and the load of the plug B increases.

An object of the present invention is to provide a structure for connecting a CATV device housing to a CATV device housing and mounting a substrate, which has a simple structure and can accommodate a wide variety of CATV device housings. .

[0005]

As shown in FIGS. 1 to 3, the structure for connecting the CATV device housing to the CATV device housing and the board mounting structure according to the present invention is as shown in FIGS. Attaching so as to project From the contact plug 3 and the peripheral wall 2, a ground mounting bracket 6 having a mounting portion 5 for mounting the substrate 4 is vertically slidably interposed, and the contact plug 3 is tightened with a nut 7. Thus, both the connecting plug 3 and the ground fitting 6 can be fixed to the peripheral wall 2.

[0006]

[Action]

 In the structure for mounting the connector and the board to the CATV device housing of the present invention, the ground mounting metal member 6 is vertically slidably interposed between the peripheral wall 2 and the connector 3 of the housing 1. 2 in the deep housing 1, lower the ground mounting bracket 6 to the bottom (until the inverted U-shaped upper end of the metal fitting 6 contacts the plug 3) and tighten the nut 7 as shown in FIG. Attach the mounting bracket 6 together, or if the chassis 1 has a shallow bottom, tighten the nut 7 with the ground mounting bracket 6 pulled up as shown in Fig. 3 to secure it. You can Therefore, even when the shape of the housing 1 or the mounting position of the board 4 is different, it is not necessary to change the board 4 or the housing 1.

[0007]

Embodiment 1 In FIG. 1 showing an embodiment of a structure for attaching a connector to a CATV device housing and a substrate according to the present invention, reference numeral 1 is a CATV device housing, which is die cast from aluminum. It is composed of a main body 11 and a lid (not shown) in which various electronic circuits are housed.

Reference numeral 3 in FIG. 1 is a plug for connecting a coaxial cable or the like, which is composed of a fitting portion 12 projecting outside and a terminal portion 13 projecting inside of the peripheral wall 2 of the housing 1. The nut 14 screwed on the fitting portion 12 side and the nut 7 screwed on the terminal portion 3 side can be fixed to the peripheral wall 2 by tightening them together. Among them, an earth mounting member 6 described below is interposed between the peripheral wall 2 on the terminal portion 13 side and the nut 7.

Reference numeral 6 in the figure is a ground mounting metal fitting made by processing a metal into a U shape, and the metal fitting 6 is placed in a state in which the terminal portion 13 is passed through the opening portion 15 formed in the U shape inside. It can be slid down. The earth fitting 4 is fixed by sliding the nut 7 up and down and tightening the nut 7 at an appropriate position.

At both ends of the lower side of the ground mounting member 6, mounting portions 5 of the substrate 4 which are bent in the horizontal direction are formed. It can be fixed with screws 16.

[0011]

[Effect of the device]

 According to the structure for mounting the connector and the board to the CATV device housing of the present invention, the ground mounting bracket 6 of the connector 3 can be slid up and down together with the board 4 attached thereto, so that the size and structure of the housing 1 can be improved. Even if it is changed, the position of the board 4 can be freely changed by appropriately moving the ground mounting bracket 6 up and down accordingly, and one ground mounting bracket 6 can be used for various housings 1. You can Further, since the plug 3 and the grounding fitting 6 are not integrated, the force applied to the substrate 4 does not reach the plug 3.
