Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drop-in line clasp used primarily for holding a telephone line drop-in line.

Conventional telephone line drop-in wire clasps have a type in which the support wire of the drop-in wire is wound once around one guide, so the number of guides must be increased to three or more due to lack of frictional force.

For this reason, conventional restraining devices are large, heavy, and costly.

The present invention provides a lead-in wire pull-down fixture that can reduce the total number of guides to two by winding the support wire around the first guide twice or more, thereby reducing the overall size. It is intended to do.

For this reason, the configuration of the lead-in line fastener of the present invention is such that the first
a main body having a guide, a second guide adjacent to one of the guides, and a support wire snap stop portion adjacent to the other;
The first guide includes a bottom plate part and a ring that protrudes perpendicularly from one end of the bottom plate part to connect the support line of the lead-in line.
For winding more than one turn, the first
The first winding has a top flange that is connected to the top of the part and has a size to prevent the support wire from coming off, and the second guide has a top flange that extends from the top flange to the second guide. The support wire has a second winding part connected in an extended manner on the opposite side of the spring stopper part, and the first winding head is connected to the spring stopper part from the other end of the bottom plate part. It has a column-shaped support wire holding part that projects vertically on the same side as the part, and a top plate part that is connected to the top of this support line holding part and has a size that prevents the support wire from coming off. Moreover, the ring is fixed to the bottom plate part, and further, the columnar first winding part forms a taper whose outer diameter decreases as it goes toward the bottom plate part. It is characterized by

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

The drawing shows an embodiment of the present invention, and the lead-in wire fastener in this embodiment consists of a main body a made of hard synthetic resin and a ring b made of wrought steel.

The main body a has a first guide 1 in the center, a second guide 2 adjacent to one of the first guides 1, and a support line snap stop part 8 adjacent to the other.

The first guide 1 also includes a bottom plate portion 3 having a rectangular plate shape, and a support line d for a lead-in wire that protrudes perpendicularly from one end of the bottom plate portion 3.
The first volume is in the form of a column of an inverted truncated cone (having a taper in which the outer diameter decreases as it goes toward the bottom plate part 3) and has a length l (see Figure 2) that can be wound twice. Part 4
The first winding has a circular plate-shaped top flange 5 which is connected to the top of the part 4 and is large enough to prevent the support wire d from coming off.

Further, the second guide 2 includes a second winding part 6 extending from the top flange part 5 to the opposite side of the support wire snap stop part 8, and has two tabs 7 connected to each other.

That is, the second guide 2, as seen in FIG.
It has a T-shape and is connected to the top flange 5 of the first guide 1.

Further, the support wire snapping part 8 includes a support wire holding part 9 which is vertically protruded from the other end of the bottom plate part 3 toward the same side as the first winding part 4 and has a columnar shape. It has a rectangular plate-shaped top plate part 10 that is connected to the top of the support wire holding part 9 and has a size that prevents the support wire d from coming off.

Further, the ring b is fixed to the bottom plate portion 3 of the first guide 1.

That is, the leading end of the ring b is firmly embedded from the inside of the bottom plate part 3 to the inside of the support wire holding part 9, as shown by the dotted line in FIGS. 1 and 2.

In the service line pull-down fixture configured as shown, the ring b is engaged with a hook C fixed to a building (not shown), and then the support line d is restrained by the support line holding part. The first winding of the first guide 1 is wound around the part 4 twice.

At this time, be sure to wrap the support wire d so that the part does not loosen.
Wrap it tightly while pulling the support wire d sufficiently.

That is, since the first winding part 4 has a taper in which the outer diameter becomes smaller as it goes toward the bottom plate part 3, the first winding is performed near the bottom plate part 3, and the next If the second winding is carried out on the side far from the bottom plate part 3, the wound part of the support wire d will inevitably be pulled towards the bottom plate part 3, forming a double coil shape and being tightly tightened. Become.

Thereafter, the support wire d is wound once around the second winding section 6 of the second guide 2.

Of course, at this time as well, the support wire d is sufficiently pulled and wound tightly.

Then, the state shown in Fig. 3 will be reached, and the service line can be held in place.

Therefore, the service line anchor of the present invention has a main body that has a first guide in the center, a second guide adjacent to one of the guides, and a support line snap stop part adjacent to the other, and a main body that is fixed to the construction line. The first guide includes a bottom plate part and a ring that protrudes perpendicularly from one end of the bottom plate part and has a supporting wire of the lead-in wire wrapped twice or more. The first winding part has a columnar shape with a possible length, and the first winding part has a top flange part that is connected to the part and prevents the support wire from coming off. has a second winding part extending from the top flange to the opposite side of the support wire snap stop part, and the ring is fixed to the bottom plate part; Of course, the ring can be engaged with the hook and used in the conventional manner, but the first winding of the first guide can be done by wrapping the support wire two or more times around the part, so that the frictional force is reduced. The exterior covering part and the first
In addition to the contact between the guides, the support wire becomes multi-coiled and the outer sheathing of the support wire comes into contact with each other, resulting in a very large and extremely stable fastening.Furthermore, the second guide Since the second winding of the wire can also be wound at the bottom, a total of two locations, the first and second, are sufficient as guides, and a part of the support wire is provided at the other end of the bottom plate. The support wire is pressed by the support wire holding part of the spring stopper part and the top plate part provided at the top of this holding part, and the elasticity of the support wire prevents it from flying off, and the first volume is attached. Wrapping at the edges not only makes the work easier, but also prevents the support wire from loosening and coming off, which not only makes it possible to downsize and reduce the overall weight.
Costs can be reduced, and in particular, since the column-shaped first winding part forms a taper whose outer diameter decreases as it goes toward the bottom plate part, it is possible to reduce costs. If the winding is done nearer to the bottom plate part, and the second and subsequent windings are done in order farther from the bottom plate part, the winding part of the support wire will inevitably be wrapped around the bottom plate part. The effects of the present invention are extremely large, as the coils are gathered together in a multi-coil shape and are tightly tightened, preventing loosening and facilitating the work of securing.
