Description

Technical Field

[0001] The utility model relates to a cable pressing device, belonging to the field of distribution cabinets. Background Art

[0002] An inlet opening is provided at the upper part of one side of the distribution cabinet, which facilitates the cable to pass through the inlet opening and enter the distribution cabinet. To prevent the cable from being pulled and causing stress at the end of the cable inside the distribution cabinet, a cable pressing structure needs to be installed outside the inlet opening. The bell mouth is a commonly used accessory for restricting the position of the cable at the inlet opening. The bell mouth is connected and fixed to the distribution cabinet by bolts or other means. Since the wall thickness of the distribution cabinet is often thin, when the cable is heavy, the part of the distribution cabinet where the bell mouth is installed is subjected to a large force, and the probability of deformation and damage to the part of the distribution cabinet where the bell mouth is installed is relatively high. Therefore, it is necessary to design a cable pressing device that disperses the force exerted by the cable on the inlet opening part of the distribution cabinet. Content of the Utility Model

The upper bushing is of a semi-circular structure. A lower bushing for wrapping the cable is arranged under the upper bushing. The lower bushing is of a semi-circular structure. Both ends of the upper bushing are respectively connected and fixed to both ends of the lower bushing by bolts. A vertically arranged stud is installed at the upper part of the outer surface of the upper bushing. The stud penetrates through a vertical hole. The vertical hole is opened at one end of a first rectangular tube for lapping on the top of the distribution cabinet. Nuts threadedly connected to the stud are respectively arranged on the upper side and the lower side of the vertical hole. A clamping plate for clamping on the side of the distribution cabinet where the inlet opening is provided is opened on the lower surface of the first rectangular tube. A first L-shaped plate for clamping on the side of the distribution cabinet is inserted into the first rectangular tube. A first screw hole is opened on one side of the upper surface of the first rectangular tube away from the vertical hole.
