Abstract
The utility model discloses a waterproof cold-shrinking sealing cap for sealing a power cable. The waterproof cold-shrinking sealing cap consists of a cold-shrinking sealing cap mainbody and a framework; and the cold-shrinking sealing cap mainbody is sheathed with one end of the framework after being expanded by external force. The framework is shaped like a cylinder and two ends of the framework have no end covers. A silicone rubber cap is used as the cold-shrinking sealing cap mainbody; and when in normal state, the aperture of the silicone rubber cap is less than the diameter of the end part of the power cable. The waterproof cold-shrinking sealing cap for sealing the power cable has a simple structure, has good waterproof and moistureproof performance, does not require fire, and can be assembled conveniently.
Description
Technical field
The utility model relates to a kind of power cable water-tight shrinkage sealing cap.
Background technology
Along with the fast development that China State Grid builds, power cable lays that scope is more and more wider, and lay length is also advanced by leaps and bounds, and the application of electric cable fitting product also increases thereupon.For the power cable termination, during construction such as rainy weather or construction site humidity, the temporary transient cable core position that disconnects the into water that makes moist easily, for this reason, on the market at present institute's cable socket that uses seal sealing cap and be the pyrocondensation form, the contraction of need getting angry, because the job site can not provide burning things which may cause a fire disaster, the pyrocondensation product can't satisfy instructions for use, and the water phenomenon takes place time and again to cause a lot of cables in job site to make moist into, thereby influences the cable electrical performance.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of power cable water-tight shrinkage sealing cap, and this power cable water-tight is simple in structure with the shrinkage sealing cap, have the excellent waterproof humidity resistance, need not get angry, easy for installation.
Technical solution of the present utility model is as follows:
A kind of power cable water-tight shrinkage sealing cap is made up of shrinkage sealing cap main body and skeleton, and shrinkage sealing cap main body is sleeved on an end of skeleton after the external force expansion.
Described skeleton is that two ends do not have the cylindric of end cap.
Shrinkage sealing cap main body is the silicon rubber cap, and during normality, the cap mouth diameter of silicon rubber cap is less than the diameter of power cable end.
Beneficial effect:
Power cable water-tight shrinkage sealing cap of the present utility model, its building block is shrinkage sealing cap main body and skeleton, and is simple in structure, need not burning things which may cause a fire disaster during use, when twitching skeleton, shrinkage sealing cap main body is shunk the end seal with power cable automatically, easy to operate, sealing effectiveness is good.
Description of drawings
Structural representation when Fig. 1 cooperates with the power cable end with the shrinkage sealing cap for the power cable water-tight.
Label declaration: 1-shrinkage sealing cap main body, 2-encapsulant, 3-skeleton, 4-power cable.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As Fig. 1, a kind of power cable water-tight shrinkage sealing cap, be made up of shrinkage sealing cap main body and skeleton, shrinkage sealing cap main body is sleeved on an end (in other words: shrinkage sealing cap main body is expanded by mechanical external force, then skeleton is placed wherein) of skeleton after the external force expansion.Described skeleton is that two ends do not have the cylindric of end cap.Shrinkage sealing cap main body is the silicon rubber cap, and during normality, the cap mouth diameter of silicon rubber cap is less than the diameter of power cable end.
In the site operation process, when needing waterproof, moisture protection that outside diameter of cable cleaning surfaces is clean as the cable socket of object of protection, wind packing matcrial at cable socket, will be enclosed within on the cable with the shrinkage sealing cap of skeleton then, twitch skeleton then.Shrinkage sealing cap main body is shunk naturally and is locked on cable, and whole cable is realized dual-seal by packing matcrial and shrinkage sealing cap main body.The utility model is a kind of simple in structure, need not employ any thermal source and just sealing cap can be installed on the cable, and is easy for installation.
Claims (3)
1. a power cable water-tight shrinkage sealing cap is characterized in that, is made up of shrinkage sealing cap main body and skeleton, and shrinkage sealing cap main body is sleeved on an end of skeleton after the external force expansion.
2. power cable water-tight shrinkage sealing cap according to claim 1 is characterized in that, described skeleton is that two ends do not have the cylindric of end cap.
3. power cable water-tight shrinkage sealing cap according to claim 1 is characterized in that shrinkage sealing cap main body is the silicon rubber cap, and during normality, the cap mouth diameter of silicon rubber cap is less than the diameter of power cable end.
