Description

[Detailed description of the invention] Industrial field of application: This invention is a new wire protection plate (hereinafter simply referred to as a protection plate) used in a fastener to hold an electric wire (cable) in a desired location. It is related to the shape, in particular, a type in which a wedge-shaped member and a sheath member are combined, the target wire is interposed between them, and the target wire is restrained and held by the relative movement of both members in the longitudinal direction (i.e., wedge action). The present invention relates to a protective plate used in a fastener.

Prior Art and Problems to be Solved: As described above, the retainer including the wedge member and the sheath member has a function that protects the wire during the above-mentioned relative movement of both members during the wire retention. Conventionally, a fifth
Generally, a protective plate 7 as shown in the figure is interposed, but this protective plate is a separate component from both members. Therefore, each time a worker performs the work of securing the parts, he or she has to carefully assemble the three separate parts, which becomes extremely troublesome and time-consuming when working at a high place. In order to eliminate this trouble, this invention proposes a protective plate that has a shape that allows it to be well connected to the sheath member and that can be quickly placed in the appropriate position with simple operation. Details of this are as explained in the next example.

Embodiment: In the figure, reference numeral 1 is a wedge member made in the shape of an upward channel bar, and both side plates 1', 1' are wedge-shaped plates whose height decreases toward the front end. Reference numeral 2 denotes a hanging ring member whose base is fixed on the inner surface of the bottom plate 1'' of the member 1 and protrudes from the front of the member 1. In this example, one wire is folded in half and the tip is attached to the hanging ring. 2' is shown.
In this example, the base of the ring member 2 is fixed by partially cutting the bottom plate 1'' inward and inserting it between the cut and raised piece and the bottom plate.
The ring portion 2' is hung on a hook provided on a retaining member (not shown) and is retained using this as a fulcrum. 3 is a sheath member, which is roughly in the shape of an upward channel bar, with both side plates 3',
3' is formed into a wedge-shaped face plate similar to that of the wedge member 1, and each upper end edge forms an edge 4 that is shallowly bent inwardly and downwardly. As can be seen in FIGS. 1 and 2, when in use, this member 3 is mounted in such a manner that the member 1 is held from below using both edges 4, allowing relative movement in the longitudinal direction of both members. In addition, a cavity is provided between the bottom plates 1'' and 3'' of both members, and the target electric wire can be held therein via a protection plate to be described later. Reference numeral 5 denotes a protection plate, and this thin plate member is made into a long and narrow strip, and a single pore 5' is formed along one longitudinal edge. This pore 5' is opened slightly larger than the link in the cross section of the lower part of the side plate 3' of the sheath member, and it is fitted into one of the side plates with a small amount of movement as shown in the figure. is connected to. In order to fit in this way, the protective plate may be inserted from above through the bent edge 4 of the side plate 3'. Reference numeral 6 denotes a non-slip surface section provided on the bottom plate 3'' of the sheath member, and is formed by partially cutting and raising the bottom plate.

To use this device, first push the protection plate 5 upward as shown in FIG. 6, pass the target electric wire a into the member 3, and place the protection plate on the upper surface of the wire. Next, fit the wedge member from the rear of the sheath member so that the bottom plate 1'' of the wedge member touches the top surface of the protection plate 5. Next, pull the wedge member forward and the target electric wire a will be connected to the sheath member. During this time, the wedge member can smoothly complete the above-mentioned pull-out movement regardless of the uneven surface of the target wire coating by interposing the protective plate. For this purpose, the upper surface of the protective plate is formed flat and is generally made of a water-resistant hard material with low slip resistance.

Effects: According to this device, the protection plate 5 is connected to the side plate of the sheath member through the pore 5', so that the operator can only touch the inner bottom surface of the member 3 when securing the wire. The protective plate located on the sheath member may be pushed upward as described above and placed on the target electric wire that is placed on the sheath member at this time. Therefore, no special effort is required for positioning during work, and the inconvenience of dropping the workpiece during work is also eliminated, making it possible to significantly increase work performance. Another great advantage is that the protection plate and the sheath member are connected by extremely simple means, so that no special processing or expensive costs are required.
