[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging ceiling.

[0002]

2. Description of the Related Art Conventionally, when an outlet or a switch is added in a private room such as a toilet or the like, it is difficult to extend the wiring. Therefore, these additional terminal fittings are built in in advance, and if necessary, a knockout type wire is used. Drill the introduction hole,
There has been proposed an adapter-type hook-type ceiling that allows an external electric wire to be connected, and that can be mechanically hung while the lighting equipment is electrically connected by inserting a hook-type plug blade.

[0003]

However, in the case of this type of conventional hanging sealing, the connection spring between the contact spring in the sealing main body and the terminal fitting is formed in a form exposed in the sealing main body. However, there is a problem in that the lead wires used for the above-mentioned methods are not coherent and are in a disordered state, so that it takes time to fit them in a predetermined wiring space.

The present invention has been made in view of the above-mentioned problems, and a purpose thereof is to easily summarize lead wires used for wiring in a sealing body such as wiring between contact springs and terminal fittings. It is an object of the present invention to provide a hook-type ceiling which is stored and is not exposed in the sealing body.

[0005]

According to the present invention, in order to achieve the above object, a pair of hooking blades inserted from a pair of hooking blade insertion holes drilled in the surface of a sealing body are electrically connected. In a hanging ceiling incorporating a pair of contact springs that are mechanically detachably held, a terminal fitting for connecting an electric wire introduced into the sealing body from the outside and the contact spring are arranged on the surface of the body during mounting in the sealing body. In addition, the wiring of the terminal fittings and the contact springs in the sealing main body is performed in the wiring space on the back of the middle body.

[0006]

According to the present invention, the terminal seal and the contact spring are disposed on the surface of the middle body, and the terminal fittings and the contact spring and the terminal spring are provided in the wiring space on the back of the middle body. Perform wiring between them. Therefore, the work of arranging the terminal fittings and the contact springs and the wiring of the lead wires can be performed by the middle body alone in advance. Also, since the lead wires are wired in the wiring space on the back of the middle body, when the middle body is attached to the ceiling body, the lead wires do not appear on the surface of the middle body, the wiring looks cleaner, and the leads vary. Is lost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments. Figure 1,
FIG. 2 is an exploded perspective view of the round hooking seal of the embodiment, and includes a body 6 made of a thermoplastic resin shown in FIG.
A sealing body is formed by overlapping a cover 7 made of a thermoplastic resin shown in FIG. 2 and integrally fixing the cover 7 with a pan-shaped small screw 8.

The body 6 is mounted on the ceiling of a building, and the mounting portions 1 having holes for inserting mounting screws for mounting the body 6 on the ceiling are equally spaced around the inner surface. In addition, a fixing portion 2 having a screw-in hole for mounting a lighting fixture is provided between the mounting portion 1 and a wire for indoor wiring to be introduced into the center of the body 6. An electric wire insertion port 3 is provided, and two holes 4 into which small screws 8 are screwed are provided.

Further, there is provided a hole 10 into which the tapping screw 9 inserted into the hole 11 of the middle body 5 is screwed. The middle body 5 is made of a thermosetting resin, and a peripheral wall 3 formed on the periphery of the opening of the electric wire insertion port 3 is provided at the center of the central portion 5A.
A is provided on the surface of the central portion 5A on both sides of the hole 12.
Contact springs 14 are arranged point-symmetrically on the surface of the central portion 5A isolated by the above.

The contact spring 14 has two sandwiching pieces for electrically contacting and mechanically holding the catching blade by sandwiching a catching blade (not shown). Reference numeral 14 denotes a mounting seat 17A extending in a reverse L shape from the tip of a terminal plate 17 fixed to the surface of the central portion 5A with a tapping screw 16, and is fixed and held by a caulking stud 18. Further, the other contact spring 14 is fixedly held by a caulking stud 20 at the tip of a Z-shaped terminal plate 19 fixed to the central portion 5A.

A terminal fitting 28 comprising a terminal plate 26 and a terminal screw 27 is disposed on the surface between the partition walls 13 in the central portion 5A. The arms 5B, 5B and the arms 5C are provided on the outer periphery of the center 5A where the contact springs 14 and the like are arranged as described above.
A pair of terminal fittings 23 each including a terminal plate 21 and a terminal screw 22 are fixed to the surfaces of the arms 5B, 5B, and 5C by tapping screws 24.

The terminal plate 21 of the terminal fitting 23 is fixed to the arm 5B with a tapping screw 24, and the terminal screw 22 is
1 is screwed into a screw hole (not shown). Also the central part 5
An oval hole 25 is formed at a position between the terminal fittings 23 of the arm portion 5B formed in a straight line with the center of A in which the mounting portion 1 of the body 6 is fitted.

As described above, the terminal fitting 23, the contact spring 14,
As shown in FIG. 3, the middle body 5 on which the terminal plates 17 and 19 are provided has a concave portion 30 forming a wiring space for the lead wire 31 on the back surface, and a small hole formed in the ceiling surface of the concave portion 30 is formed. The lead wires 3 are connected between the terminal plates 21 or between the terminal plate 21 and the terminal plate 17 or 19 and further between the terminal plates 26.
1, and the lead wire 31 is housed as shown.

When the wiring of the lead wire 31 is completed, the middle body 5 is fixed to a predetermined position on the inner surface of the body 6 with a tapping screw 9. If the inserted small screw 8 is screwed into the hole 4 of the body 6, the hooking sealing is completed. The notches 32 opened on both sides of the body 6 are holes for connecting the moldings. The cover 7 has a blade insertion hole 3 for inserting a hook blade.
3 and an oval hole 34 for exposing the fixing portion.

[0015]

According to the present invention, there is provided a pair of contact springs for electrically connecting a pair of hooking blades inserted from a pair of hooking blade insertion holes perforated on the surface of a sealing body and mechanically detachable. In the ceiling with built-in
A terminal fitting for connecting an electric wire introduced from the outside into the sealing body and the contact spring are disposed on the surface of the middle body to be mounted in the sealing body, and the wiring of the terminal fitting and the contact spring in the sealing body is connected to the back of the middle body. Since it was done in the wiring space of the part, the work of arranging the terminal fittings and contact springs and the wiring of the lead wires can be done in advance by the middle body alone, and the work of storing the lead wire storage space becomes easier, and the resulting assembly Workability is improved, and lead wires are routed in the wiring space behind the middle body.
When the middle body is attached to the ceiling body, there is an effect that the wiring of the lead wire does not appear on the surface of the middle body, and the wiring becomes clean.
