A terminal portion for a subsequent cable is formed on either the front or back side of the kung, and it can be used in either an exposed type or an embedded type.

(Embodiment) As shown in FIGS. 1 and 2, the housing 1 includes a body 11 made of an insulating material such as synthetic resin, and a terminal unit 12. The body 11 is formed in the shape of a rectangular frame extending vertically in FIG. An elastic piece 13 whose lower end is continuous with the side circumferential wall and whose upper end is inclined inward of the body 11 is formed at one place on both side circumferential walls at both longitudinal ends of the body 11, and the upper edge of the elastic piece 13 is connected to the side circumferential wall. This is the lower edge of the engagement hole 14 formed in the peripheral wall. On the other hand, the terminal unit 12 includes a metal shield plate 15 and a terminal block 16 made of an insulating material such as synthetic resin. The shield plate 15 has a connecting tongue piece 17, and by engaging the engaging tongue piece 17 in an engaging hole 14 formed in the body 11, the body 11 and the terminal unit 12 are connected. There is. That is, if the terminal unit 12 is inserted into the body 11 from below in FIG.
The end unit 12 can be inserted into the body 11 by the elastic piece 13 bending outward when pressed by the engagement tongue 17. When the engagement tongue piece 17 is inserted into the engagement hole 14, the elastic piece 13 13 returns, and the engaging tongue piece 17 and the engaging hole 14 engage with each other. Since the terminal unit 12 is mounted inside the body 11 in this manner, there is no need to use screws or the like, and assembly can be carried out efficiently.

A terminal portion 2 for connecting the coaxial cable 3 is formed on the upper surface of the terminal unit 12 in FIG. 2, and the terminal portion 2;
Three coaxial cables 3 can be connected here. As shown in Fig. 3, two coaxial cables 3 are connected to the terminal section 2.
A first terminal 2a to which the two coaxial cables 3 are connected at the same time, and a second terminal 2b to which only one coaxial cable 3 is connected are provided. The first terminal 2a has a pair of protrusions 21 extending through the shield plate 15, and the second terminal 2b has one protrusion 21. As shown in FIG. 6, an insertion hole 22 is formed in the distal end surface of each protrusion 21. As shown in FIG. A pair of contact spring pieces 23 that come into elastic contact with each other are housed in the protruding base 21, and the coaxial cable 3 inserted through the insertion hole 22
The center conductor 3a is sandwiched between both contact spring pieces 23, and the center conductor 3a is connected to the contact spring pieces 23.

Each holding piece 26 has a holding plate 28 disposed opposite to the surface of the shield plate 15 at a position different from that of the protrusion 21.
is held open and closed. A fixing screw 29 is inserted into the holding plate 28 as a fixing member, so that the holding plate 28 can be fixed to the shield plate 15 in a closed state.

Therefore, as shown in FIG. 6, the tip of the center conductor 3a of the coaxial cable 3 is folded into a substantially rectangular shape, and the center conductor 3a is inserted into the insertion hole 21, and the center conductor 3a is inserted into the contact spring piece 23. Connect the outer conductor 3b to the shield plate 15 and the holding plate? By tightening the fixing screw 29 while holding the coaxial cable 3 between the shield plate 15 and the coaxial cable 8, the outer conductor 3b can be connected to the shield plate 15 and the coaxial cable 3 can be fixed to the housing 1. The input/output ends of a distribution circuit mounted on a printed circuit board (not shown) in the housing 1 are connected to the terminals 2 at 2 b, with the first terminal 2 a being the output side and the second terminal 2 b being the output side. is connected to the input side. In other words, a distribution circuit that divides the input into two is mounted on the printed circuit board. As shown in FIG. 4, terminal 2g,
The leading direction of the coaxial cable 3 from 2 b is the same for all terminals 2 at 2 b,
All coaxial cables 3 can be led out from one side of the housing 1. In other words, there is an advantage that the coaxial cable 3 does not get tangled during the wiring work, and the wiring work becomes easier. In particular, when installing it in an embedded box as described later, the coaxial cable 3 from the embedded box
This makes it easier to derive and improves work efficiency.

By the way, the housing 1 is twice as wide as the standardized ready-made wiring module in the left and right directions, and the left and right edges are equipped with standardized ready-made wires made of synthetic resin that can be attached to an embedded box. Connecting claw 1 that can be connected to the mounting frame 5 of
8 is provided protrudingly.

Four coupling claws 18 are provided on each of the left and right edges of the housing 1, and correspond to two monorail wiring devices. Further, a coupling hole 19 is formed at a position corresponding to between each pair of coupling claws 18 and on the left side of the coupling claw 18 in FIG. 1(b).
By inserting a retaining claw provided in a ready-made metal mounting frame into the metal mounting frame, the device can be attached to and removed from the metal mounting frame. Furthermore, a mounting hole 6 is formed in the body 11 at a position different from that of the terminal portion 2, and the mounting hole 6 penetrates in a direction perpendicular to the plane of the paper in FIG. 1(a). The housing 1 can be fixed to a wall or the like by screwing the tip of the screw into the wall or the like. In other words, the housing 1 can be used with it exposed on a wall or the like.

On the other hand, if the connecting claws 18 and the connecting holes 19 are used, it can be used as an embedded type by being attached to the mounting frame 5 used for a standardized commercially available wiring device that is attached to an embedded box. The mounting frame 5, which can be attached using the connecting claws 18, is made of synthetic resin! As shown in Figure #7, a window hole 51 is formed in the center. The left and right width of the window hole 51 is 2
Both double-width wiring devices are designed to be compatible with modules. A holding hole 52 into which a connecting claw 18 provided on one side edge of the housing 1 is inserted is bored on one side of the mounting frame 5, and three monoyl wiring devices can be attached to this mounting frame 5. A total of six holding holes 52 are provided in three pairs each. An insertion hole 53 is formed on the other side at a position corresponding to the coupling claw 18, and a release piece 54 is provided within the insertion hole 53. The release piece 54 has an operation piece 55 attached from one side edge of the front side of the mounting frame 5! , and shoulder portions 56 are formed on both sides of the operating piece 55. Therefore, a gap is formed between the periphery of the insertion hole 53 and the shoulder portion 56 into which each coupling claw 18 can be inserted. By inserting the coupling claw 18, the housing 1 is coupled to the mounting frame 5. Since the mounting frame 5 is made of synthetic resin and has flexibility as described above, the mounting frame 5 is I)
To remove the housing 1, pry the operation piece 55 with a jig such as a screwdriver and spread the release piece 54 outward to release the coupling claw 18.
The engagement state between the insertion hole 53 and the insertion hole 53 can be released. A pair of elongated holes 57 for attaching to the embedded box are formed in the remaining sides of the mounting frame 5, and a screw hole 58 for attaching a decorative panel is formed.

The above-mentioned housing 1 corresponds to a wiring device monoyl whose left and right width is twice the width, and both wiring devices have a vertical width that is larger than the width of one monoyl and smaller than the width of two monoyl.
When this housing 1 is attached to the mounting frame 5, the eighth
As shown in the figure, the window hole 51 of the mounting frame 5 leaves an opening for one or more wiring device modules. Therefore, when connecting the coaxial cable 3 that is routed inside the wall and drawn out into the embedded box to which the mounting frame 5 is attached to the terminal section 2 provided on the front side of the mounting frame 5, the coaxial cable 3 is connected to the terminal section 2 provided on the front side of the mounting frame 5. It can be pulled out to the front. Furthermore, since the ready-made mounting frame 5 is used, parts can be shared with the embedded box and the ready-made wiring module, which leads to cost reduction.

As described above, it can be used both as an embedded type using the mounting frame 5 and as an exposed type using fixing screws, so the usage type can be changed as necessary. This allows you to choose and expand the number of places you can use it.

In the above-mentioned embodiment, a two-distribution type distributor was illustrated, but it goes without saying that the same effect can be obtained by using a four-distribution type distributor as shown in FIG.

[Effects of the Invention] As described above, the present invention has a housing equipped with a connecting part that can be detachably connected to a standardized ready-made mounting frame that can be attached to an embedded box, and can be attached to a suitable place on the housing. A mounting hole is drilled through the front and back sides through which screws can be inserted, and a terminal section for subsequent cables is formed on one side of the housing.The housing can be used as an embedded type by attaching the housing to a ready-made mounting frame. It also has the advantage of expanding the range of usage patterns because it can be used as an exposed type by inserting a mounting screw fixed to a wall surface or the like into the mounting hole.
