Description

Cable Support Clamp

The present invention relates to, for example, a cable support clamp for gripping and supporting a cable bundle or an electric wire protection tube, and more particularly, to a cable support clamp configured to easily support a cable bundle or an electric wire protection tube.

In the case of wire or cable wiring work, it is necessary to ensure that the wires or cables are not entangled and well supported, and various cable clamps or cable trays are used for this purpose.

Figure 5 shows the cable clamp most widely used in the prior art. The cable clamp is a pair of bases 5 fixed to a wall, and a pair of gripping or wire protection tubes 7 (hereinafter referred to as "cables") (see Fig. 6) provided on the base 5 to hold various cable bundles. It comprises a gripping clip (6) (6). The base 5 has a channel shape, and fastening holes (not shown) are formed at both sides of the central portion, and ends of both flanges 51 and 51 are curved inward. The gripping clip 6 has fastening holes 61 and 61 formed at an upper end thereof, and gripping parts 62 and 62 curved in an arc shape at an end thereof, and both ends of the base 5 are formed at both ends of the gripping clip 6. Engaging projections 63 and 63 which are engaged with the bent portions of both flanges 51 and 51 are formed, respectively. The coupling protrusions 63 and 63 are formed by indenting both portions between the lower end portion and the stop portion of the gripping clip 6 inwardly.

Therefore, as shown in FIG. 6, when a pair of gripping clips 6 and 6 are pushed on both sides of the base 5 in directions facing each other on both sides of the base 5, both sides of the gripping clips 6 are provided. As the bent portions of both flanges 51 and 51 of the base 5 are inserted into the recessed portions of the base 5, the engaging protrusion 63 is caught in the lower portion of the bent portion. Therefore, the holding clip 6 is in a state in which it is slidable in the longitudinal direction of the base 5, and is in a state where it cannot be pulled out to the upper portion of the base 5. When both gripping clips 6 and 6 move in a direction facing each other, they are met at the center of the base 5, and therefore, both gripping clips 6 and 6 and both gripping clips between the base 5 are separated. The gripping portions 62 and 62 of 6) and 6 form a substantially cylindrical cable passage through which the cable 7 can pass. In order to support the cable 7, the base 5 is fixed to the wall by fastening the screw right to the wall through the fastening hole of the base 5. Next, both gripping clips 6 and 6 are inserted into the base 5, and the cable 7 is positioned between both gripping clips 6 and 6. As shown in FIG. Next, by pushing both gripping clips 6 and 6 in a direction facing each other, the upper end portions of both gripping clips 6 and 6 are brought into contact with each other so that the cable 7 is connected between the gripping clips 6 and 6. Be gripped. Next, the support work of the cable 7 is completed by fastening the bolt and the nut 65 through the upper end fastening holes 61 and 61 of both gripping clips 6 and 6.

However, in the conventional clamp as described above, there are the following problems.

First, since the gripping clip 6 is detachably attached to the base 5 in a sliding manner, it is not only inconvenient to couple the gripping clip 6 to the base 5, but also several bases 5 and gripping clips 6. It is more inconvenient because you have to carry them separately.

Secondly, since both the gripping clip 6 may come off the base 5 during operation and the cable 7 may come off, the gripping clips 6 and 6 are fixed by bolts and nuts 65. The work clip is bad because the work must be held by holding the grip clip (6) until the hand, and thus the hand is not free, which causes trouble in other motions, which also takes a lot of work time.

Third, since the gripping clip 6 is in a state of being movable along the cable 7 or the base 5 even after the cable 7 is gripped and supported by the clamp, the base 5 is moved by the flow of the cable 7. ), Both gripping clips 6 and 6 holding the cable 7 may come off. When both gripping clips 6 and 6 are separated from the base 5, the cable 7 supporting effect is lost at all. In particular, when the cable 7 is vertically supported, both grip clips 6 and 6 are more likely to be separated from the base 5.

Fourth, the shape of the cable passage is close to the cylinder, but since the lower shape of the base passage is straight by the upper end of the base 5, not only the grip state of the cable 7 is good, There is a greater risk that both gripping clips 6 and 6 are disengaged.

Fifth, since both concave portions exist between the lower end portion and the stop portion of the gripping clip 6, the width of the portion is narrow, the strength is weakened, and the gripping clip 6 may be easily broken.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a clamp made to facilitate the support of the cable bundle or the wire protection tube.

Another object of the present invention is to provide a clamp which is configured so that both gripping clips gripping the cable bundle or the wire protecting tube from the base fixed to the wall are not detached at all.
