DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a messenger wire temporary stopper for an electronic device used by suspending it on a messenger wire stretched outdoors.

[0002]

2. Description of the Related Art Attachment of an electronic device to a messenger wire is performed by fitting a wire attachment portion to the messenger wire in a high place where a scaffold is poor, so that the wire attachment portion does not come off from the messenger wire. This involves a difficult operation of mounting the device with a tightening bolt while holding the device. Therefore, for example, as shown in FIG. 7, a locking body 53 fixed to the main body 51 of the co-listening device at a base portion 52 and a holding groove 55 at the distal end facing the locking groove 54 of the locking body 53 are provided. And a messenger wire mounting tool 58 comprising a holding body 56 which is disposed so as to be able to approach and separate from the locking body 53 and a fastening bolt 57 which is inserted through the locking body 53 and screwed to the holding body 56.
It is proposed that a temporary wire fastener 62 in which a stopper 61 with a spring 60 is rotatably tilted is provided at a position of the main body 51 opposite to a projection 59 projecting from a lower end of the distal end of the locking body 53. Was done. The temporary wire fastener 62 is provided with the stopper 6.
By pressing the wire 1 against the messenger wire 63 and taking in the messenger wire 63, the messenger wire 63 does not come off, so that the electronic device can be securely mounted.

[0003]

However, the wire temporary stopper 62 has a complicated structure. In addition, the locking body 53
Since the gap between the projection 59 and the stopper 61 is located on the opposite side of the operator and is difficult to see, the stopper 61 is pressed against the messenger wire 63 without damaging the spring 60, and the messenger wire 63 is taken in. Requires a considerable allowance for the amount of deflection of the spring 60. For this reason, there is a problem that the wire temporary stopper 62 becomes large and the manufacturing cost increases.
Also, when removing the co-listening device from the messenger wire 63, the removal is performed in a state where the stopper 61 is pressed down against the spring 60, so that the work efficiency is reduced. Becomes

[0004] It is an object of the present invention to provide a messenger wire temporary stopper for an electronic device which can solve the above-mentioned problems.

[0005]

According to the present invention, there is provided a fastener for fixing a base portion to a housing of an electronic device and suspending the base portion on a messenger wire with an intermediate wire groove, and a wire receiving portion facing the wire groove. And a guide for guiding the holding metal so as to be able to approach and separate from the holding metal, and a messenger wire mounting tool having a tightening bolt inserted into the holding metal and screwed to the holding metal. , The base part is fixed to the housing side, the middle part elastically abuts against the side wall of the fastener, and the tip part allows the Messenger wire to enter the wire groove, but prevents the wire from getting out after entering And a locking part provided on the upper part of the stopper to lock the tip of the wire releasing stopper.

In the present invention, "the bent portion which allows the messenger wire to enter the wire groove at the distal end portion but prevents the wire from coming out after entering" is the bent portion which is formed by the messenger wire. When the wire pressing force is applied from the outside to the inside of the bent portion, it is elastically deformed and opens, but when it is applied from the inside to the outside, it means that it does not open.Specifically, for example, the tip side of the elastic filament is downward. This is achieved by forming a bent portion that bends in an inverted V shape.

According to this means, when the bent portion of the wire stopper is pressed against the messenger wire, the messenger wire can be taken into the bent portion, but the messenger wire taken into the bent portion can be taken in. The wire will no longer fall out. Therefore, attachment of the electronic device to the messenger wire becomes easy.

In order to remove the electronic device from the messenger wire, the distal end of the wire stopper is previously hung on the locking portion of the stopper, so that the electronic device can be removed regardless of the wire temporary stopper. it can.

[0009]

Embodiments of the present invention will be described with reference to the drawings. TV signal amplifier 1 as electronic equipment
As shown in FIG. 5, the messenger wire mounting tool 2 is provided on the upper surface 4 of the main body 3 constituting the housing 10 with the lid 5 and near the left and right lids 5, respectively. The stopper 6 is provided on one outer side surface 7 of the messenger wire attachment 2.

The messenger wire temporary stopper 6 includes a wire strip 8 having a high elasticity as a wire stopper and a locking portion 9 for locking the tip thereof. The wire retaining wire 8 is formed such that the base thereof is
A pin portion 14 to be inserted into a pin hole 13 formed in
The pin holes 13 intersect with the main body mounting surface 16 of the stopper 15 detachably attached to the main body 3, and the stopper 15
Straight portion 1 fitted in a groove 17 orthogonal to one outer surface 7
8, an intermediate portion protrudes from the outlet of the groove 17 above the end of the linear groove 20 of the one outer surface 7 of the stopper 15 and is elastically attached to the one outer surface 7 of the stopper 15. Along the outer surface 7 to the middle so that it comes into contact with the force,
From the middle to the front is a bent portion 21 which is bent slightly inward from one of the outer surfaces 7 (see FIG. 2), and the tip portion is bent obliquely downward in a substantially inverted V-shape. The bent portion 24 covers most of the intake portion 22, and the bending angle θ is selected such that an upward rotational force is generated by the pressing force of the messenger wire 25.

The locking portion 9 for locking the leading end of the wire 8 for retaining the wire is a concave portion formed on the upper part of one outer surface 7 of the stopper 15 fixed to the main body 3 with bolts 27.
Note that, instead of this concave portion, a hole portion into which the tip of the wire retaining wire 8 is loosely fitted, or a projecting portion that locks may be used.

The messenger wire attachment 2 has a base 1 fixed to the main body 3 and has a wire groove 20 for hanging a messenger wire 25 on a lower surface near the tip.
5. Wire receiving portion 2 facing wire groove 20 of the metal fastener
9, a pair of guides 31, 31 on both sides thereof for guiding the wire holding portion 29 so as to be able to approach and separate from the wire groove 20, and are screwed to the holding member 30 by passing through the stopper 15. The tightening bolt 3 is provided.
The metal wire 25 supplied between the wire groove 20 and the wire receiving portion 29 is clamped by the cooperation of the presser fitting 30 and the stopper 15 which are pushed up by the tightening of 2. Note that the messenger wire attachment 2 shown in FIGS.
Makes it possible for the fastening bolt 32 screwed into the middle of the holding member 30 to abut on both the horizontal surface portion 33 which is the front half of the upper surface of the stopper 15 and the inclined portion 34 which is the rear half thereof. A locking projection 35 for locking the base end portion of the presser fitting 30 is projected from the lower surface of the presser fitting 30.
Are configured to rotate in a direction to push up the messenger wire 25 with the contact point with the locking projection 35 as a fulcrum.
Note that the messenger wire attachment is not limited to the above-described configuration. Raised configuration and other appropriate configurations may be adopted.

[0013]

As described above, according to the present invention, the messenger wire temporarily stopped with a simple and inexpensive structure can reliably prevent the messenger wire taken into the electronic device from coming off. At the same time, there is an excellent effect that the electronic device can be easily and quickly taken out from the messenger wire.
