Abstract
The utility model relates to a special-shaped sealing ring, which is a rubber sleeve, the rubber sleeve is arranged in a cable penetration of a control box and sleeved on the periphery of the cable to hermetically connect the cable and the control box; the peripheral surface of the rubber sleeve is a conical surface, the end surface of one end of the rubber sleeve is a semi-circular arc surface, and the semi-circular arc surface is connected with the small end of the conical surface; the diameter of the large end of the conical surface is larger than that of the cable penetration opening, and the diameter of the small end of the conical surface is smaller than that of the cable penetration opening. The cable plugging device is reasonable in design and simple in structure, and can effectively plug a cable penetrating port of the control box to prevent leakage; and is convenient to install.
Description
Technical Field
The utility model relates to a distribution technical field, concretely relates to special-shaped sealing ring.
Background
The gap of the cable penetration opening is small, generally only 1-2mm, and liquid plugging materials are selected and cannot be met due to the fact that the liquid plugging materials cannot be fixed and are prone to leakage, so that soft rubber materials are required to be selected and plugged, but the gap is small, and the soft rubber materials cannot be plugged into the gap forcibly.
Disclosure of Invention
The utility model provides a special-shaped sealing washer for shutoff cable and electric cabinet.
The technical scheme of the utility model:
a special-shaped sealing ring is a rubber sleeve, the rubber sleeve is arranged in a cable penetrating port of a control box and sleeved on the periphery of a cable to hermetically connect the cable and the control box; the peripheral surface of the rubber sleeve is a conical surface, the end surface of one end of the rubber sleeve is a semi-circular arc surface, and the semi-circular arc surface is connected with the small end of the conical surface; the diameter of the large end of the conical surface is larger than that of the cable penetration opening, and the diameter of the small end of the conical surface is smaller than that of the cable penetration opening.
When the sealing ring is used, a cable firstly penetrates through the rubber sleeve, then the rubber sleeve is pressed into a cable penetrating port on the control box, and the cable penetrating port is plugged; the sealing ring is convenient to plug into the gap by adopting a conical surface design, but a gap is inevitably left between the small end of the conical surface and the bottom plate of the control box, and the sealing effect cannot be ensured; preferably, the skilled person can select suitable dimensions according to the actual requirements.
A ring bulge is arranged on the periphery of the other end of the rubber sleeve; thus, after the rubber sleeve is pressed as before, the annular protrusion is in sealing contact with the bottom plate of the control box, thus, the double sealing ensures that the plugging effect is better,
an annular pressure groove is formed in the end face of the other end of the rubber sleeve; the pressure groove is designed so that the rubber sleeve can be pressed into the cable insertion opening by downward force of the hard rectangular tooth tool.
The utility model has the advantages of reasonable design and simple structure, and can effectively plug the cable inlet of the control box to prevent leakage; and is convenient to install.
Drawings
Fig. 1 is a half-section schematic view of a profiled sealing ring.
Fig. 2 is a schematic view of the use of the profiled sealing ring.
In the figure, a conical surface 1-1 of a rubber sleeve 1 is a semi-arc surface 1-2, a ring is convex 1-3, a pressure groove 1-3 controls a box 2, and a cable 3.
Detailed Description
As shown in fig. 1-2, a special-shaped sealing ring is a rubber sleeve 1, the rubber sleeve 1 is arranged in a cable penetration of a control box 2 and is sleeved on the periphery of a cable 3 to hermetically connect the cable 3 and the control box 2; the peripheral surface of the rubber sleeve 1 is a conical surface 1-1, one end of the rubber sleeve 1 is a semi-arc surface 1-2, and the semi-arc surface 1-2 is connected with the small end of the conical surface 1-1; the diameter of the large end of the conical surface 1-1 is larger than that of the cable penetration port, and the diameter of the small end of the conical surface 1-1 is smaller than that of the cable penetration port; the periphery of the other end of the rubber sleeve 1 is provided with a ring bulge 1-3; and the end face of the other end of the rubber sleeve 1 is provided with an annular pressure groove 1-4.
Because of the limited character expression, there exist practically unlimited specific structures, and it will be apparent to those skilled in the art that a number of improvements, decorations, or changes may be made without departing from the principles of the present invention, or the above technical features may be combined in a suitable manner; such modifications, variations, combinations, or adaptations of the invention using its spirit and scope, as defined by the claims, may be directed to other uses and embodiments.
