Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holding device for a telephone line, and in particular to a holding device for a telephone line between a terminal box at the end of an underground cable and a telephone set 1.

In recent years, telephone lines have been made using underground cables, and at present there is no suitable anchor for the telephone line between the terminal box at the end of the underground cable and the telephone box, and all cables rely on the old-fashioned hook hooking method. This makes installation in the building troublesome, and the telephone wire for one telephone must be tied down in two places, one on the terminal box side and one on the telephone side. This was inconvenient because it required a large number of tools and also required space for installation.

The present invention requires only one telephone line anchoring part for one telephone, and by arranging many of these anchoring parts in parallel on one board, a large number of telephone wires can be anchored even in a relatively narrow space. Moreover, it is an object of the present invention to provide a telephone line anchor that can be easily installed in a building.

For this reason, the configuration of the present invention is such that the telephone line anchor between the terminal box at the end of the underground cable and the telephone terminal has at least three columnar parts each having a flange at the top and protruding from the surface of the board. A plurality of sets of telephone line holding parts are provided,
Moreover, the board is characterized by having screw holes for attachment to a building.

An embodiment of the present invention will be described below with reference to the drawings.

In the drawing, a stands for a telephone line holding device, b stands for a hollow rising pillar that accommodates and protects telephone cables from underground, C stands for a terminal box installed at the top of the standing pillar, d stands for a telephone line, and e stands for This is the telephone line holding section.

The retaining portion e connects the three columnar portions 2, 3, and 4 to one
Established as a group.

These columnar parts 2, 3, and 4 of the housing protrude from the surface of the substrate 1, and the columnar part 2 has a flange 6 on the top, and the columnar part 3 has flange 7 and 8 on the top. The top of the portion 4 has a collar 9.

Note that the substrate 1, the columnar parts 2, 3, and 4, and the collars 6, 7, 8, and 9 are integrally formed of synthetic resin.

In addition, 5 is a guide protrusion, 10 is a screw hole for mounting, and 11 is a partially occluded line concentrator ring made of steel wire that is partially embedded and fixed in the substrate 1.

Normally, the number of telephone wires d drawn out from one terminal box C is six or less, so as shown in FIG. Attachment part e to 6
A columnar part 3 is provided in the middle of one set.
The amount of protrusion from the substrate 1 is set to a certain level, and flanges 7 and 8 are provided on both of the top portions.

The telephone line anchorage a constructed in this way is fixed to the building with appropriate screws using the screw holes 10, and each telephone line d from the terminal box C is connected to the wire collecting ring 11. After passing through the cutout and securing the wire with the ring 11, the wire is connected to the desired telephone set via each telephone line holding part e.

That is, to explain one telephone line d, as shown in FIG. 1, after passing it through the ring 11, first, it is placed along the outer periphery of the columnar part 2 (the outer periphery where the collar 6 is located), Next, wrap L once around the outer circumference of the columnar part 3 (wrap it from the side with the collar 8 to the side with the collar 7, and then wrap it around the upper part of the collar 8), and then wrap it around the outer circumference of the columnar part 4 ( (the outer periphery of the side with the flange 9), and finally the outer periphery of the guide protrusion 5, and then connect it to a predetermined telephone set.

In this way, the telephone line d is secured at the telephone line retention section e.

That is, the telephone line d held in place in this manner is accidentally detached from the telephone line retaining part e due to the presence of the collar 6 of the columnar section 2, the collars 7 and 8 of the columnar section 3, and the collar 9 of the columnar section 4. It is locked without any problem.

Therefore, the telephone line anchor of the present invention is different from the old hook hooking method because it is equipped with multiple sets of telephone line anchors each consisting of at least three columnar sections protruding from the surface of the board. Unlike this, a large number of telephone lines can be secured with one fastener, which is advantageous in terms of space, and the board of the casing has screw holes for installation, making it easy to install in buildings. Since the top of each columnar part has a flange, the telephone line will not come off unnecessarily and will be securely latched, so the effects of this invention are extremely large.
