[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention makes it possible to easily attach a modular rosette to an arbitrary place of an existing telephone line indoor line.

[0002]

2. Description of the Related Art Conventionally, when changing the installation location of an existing telephone, it is necessary to cut an unnecessary line when the indoor line is long and to attach it to a new indoor line terminal through a rosette. Also, the installation location is planned in advance, and the unnecessary rosette is always installed.

[0003]

This invention adopts the following means in the prior art as described above in order to eliminate wasteful disposal of indoor lines or unnecessary uneconomical installation of rosettes. Is.

[0004]

[Means for Solving the Problems] That is, three parts of a base A, a pedestal B, and a fixing ring C are formed, and the base A
Is formed with a male screw groove N on the circumferential side surface, a groove 1 for holding an indoor wire L is formed on the surface diameter line, and a hole 2 is bored in this groove 1 L is held, and pedestal B is placed on top of it, and modular contact 4 is placed on this pedestal B.
Is fixed, a pair of protrusions 5 protruding from the back surface of the modular contact 4 are in contact with the indoor line, and the overhanging edge 7 of the fixing ring C is superposed on the peripheral side edge BF of the pedestal B. A structure in which the female screw groove M formed on the surface is screwed into the male screw groove N of the base A and deeply tightened to pierce the pair of protrusions 5 into the indoor wire L and electrically contact the twin core wire. Is.

[0005]

Since the present invention is constructed as described above, the existing indoor line is held in the groove 1 of the base A, the pedestal B is superposed on the groove, and the fixing ring 2 tightens the two so that they are modular. The poles 5 serving as the two poles of the contact 4 can be brought into contact with the two-core wire of the wiring with one touch, and the installation location of the telephone or the installation of a new telephone can be carried out by extremely simple work.

EXAMPLE 1 This attachable modular rosette comprises a combination of a base A, a pedestal B, a fixing ring C and a cover D. The base A has a circular shape with a required planar shape,
A thickness portion having a male thread groove N formed on the circumferential side and a base A1 having a diameter smaller than the diameter of the male thread groove forming portion are integrally formed on the bottom surface,
At the time of mounting, the base A1 is coated with an adhesive to fix the rosette at a required position.

On the surface of the base A, a groove 1 having a depth suitable for the thickness and width of the indoor line L is formed over the diameter line. 2 are formed so as to project, and a pair of positioning holes 3 are formed on both sides of the groove 1.

The pedestal B has a circular shape conforming to the plane shape of the base A, and a collar BF is integrally formed on the circumference of the pedestal B, and a step between the collar surface and the main body surface has a protruding edge 7 of a fixing ring C described later.
It is taken to be equal to the thickness of. A pair of projecting bodies B1 each having a rectangular shape in plan view are formed by being distributed centering on the diameter line of the surface of the pedestal B, and the distance between the two is adapted to match the width of the modular contact 4. The modular contact 4 is fixed between the protrusions by an appropriate means such that the opening peripheral side of the modular contact 4 faces outward, for example, a method of attaching and fixing a claw on the peripheral side of the protrusion B1.
A pair of polarizable protrusions 5 that are integrally attached to the bottom surface of the modular contact 4 are provided, and the protrusions 5 penetrate the main body and project to the bottom surface of the pedestal, and are formed in the bottom surface of the groove 1 of the base A. It is due to the length reaching the hole 2.

On the bottom surface of the pedestal A, a positioning hole 3 for the base A is provided.
A pair of locating pins 6 that conform to the above are projected.

The fixing ring C is formed with a female screw groove M which is screwed into the male screw groove N of the base A on the inner peripheral surface thereof, and an overhanging edge 7 matching the flange BF of the pedestal B is formed at the ring mouth end. Are integrally molded.

The cover D has a hemispherical shape that fits the inner diameter of the protruding edge 7 of the fixing ring C, has a notch D1 that fits the opening side of the modular contact 4 on the front surface, and has several notches on the circumference. A locking claw D2 is provided so as to project, and a locking hole B2 matching the locking claw D2 is formed on the surface of the pedestal B.

In assembling the above-mentioned parts, first, an adhesive is applied to the base A1 on the back surface of the base A, and the indoor line L
Is held in the groove 1 and is adhesively fixed to the mounting point. Next, the pedestal B is placed on the base A by aligning the positioning pins 3 and the holes 2 of the base and the pedestal, respectively, and the protrusions 5 of the modular contact 4 are positioned on the two-core wire of the indoor line L. When the pedestal B is covered with the fixing ring C, and the female screw groove M is screwed into the male screw groove N of the base A and tightened, the protrusion 5 pierces the coating of the two-core wire and contacts the two-core wire. The indoor line L and the modular contact 4 are placed in a state in which they can be energized. Finally, the cover D is covered on the pedestal, and the locking claw D2 is locked in the locking hole B2.
Fit and lock.

[0013]

Second Embodiment In this embodiment, the base A, the pedestal B, and the fixing ring C are formed into a quadrangular shape in a plan view, and the fitting surfaces of the base A and the fixing ring C are oriented inward so as not to be easily separated after fitting. A taper surface is provided, an uneven fitting portion is provided, or a means for fixing the base A toward the base A from the outside with a set screw is used. Since other configurations are the same as those in the first embodiment, detailed description will be omitted.

In this embodiment, since both the base A and the pedestal B have a rectangular shape, no pin or hole for positioning is required.

A U-slit type protrusion is used as the protrusion 5 of each of the above-described embodiments.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, firstly, when changing or newly installing a telephone installation place, a modular rosette can be easily and surely installed at any place on an existing indoor line. Since it can be installed, there is an effect that the work such as changing the installation location of the telephone can be carried out extremely efficiently.

Secondly, the indoor wire and the modular contact can be electrically connected with one touch only by the operation of stacking the pedestals, which are the two poles of the modular contact, on the base and tightening them with the fixing ring.

Thirdly, each part is a practical device having an excellent effect that it can be manufactured by molding and the modular contact can be easily assembled, so that it can be manufactured inexpensively and put on the market.
