Abstract
The invention discloses a cable sealing structure of an immersible pump. The structure comprises a pressing piece, a cable mould pressing plug, a cable joint and a shell, a mounting hole is formed in the shell, the cable joint is arranged in the mounting hole, glue filling is performed between the outer wall of the cable joint and the inner wall of mounting hole to form first seal, and when the pressing piece performs pressing, the cable mould pressing plug is pressed to deform, and second seal is formed. The cable sealing structure is reasonable in design and simple in structure, the higher sealing grade is achieved through two-stage seal, and meanwhile the structure is convenient to mount and suitable for mass production.
Description
Technical field
The present invention relates to a kind of cable seal structure, be specifically related to a kind of submerged pump cable sealing structure.
Background technology
Because the special environment for use of immersible pump requires its higher grade of cable seal, therefore the sealing of submersible pump cable is one of emphasis of immersible pump structural design, and the submerged pump cable sealing structure of prior art is often because unreasonable structure causes sealing difference or the defects such as inconvenient are installed.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of submerged pump cable sealing structure.
For achieving the above object, the technical solution used in the present invention is: submerged pump cable sealing structure, comprising:
Housing, described housing is arranged on described immersible pump, on described housing, is formed with installing hole;
Cable adapter, described cable adapter is arranged in described installing hole, and described cable adapter outer wall and described installing hole inwall form the first seal by encapsulating;
Cable molded plug, described cable mold pressing joint extends in described installing hole at least partly, and described cable mold pressing joint and described cable adapter are electrically connected;
Compressing tablet, described compressing tablet is fixedly installed on described cable mold pressing joint, when described compressing tablet compresses, described cable mold pressing joint distortion, described cable mold pressing joint and described installing hole inwall form the second seal.
Preferably, described cable molded plug is made by elastomeric material.
Preferably, described cable adapter is fixed in housing installing hole by screw thread or seam step.
Preferably, described cable adapter contains at least one contact pin, and expose at described contact pin two ends, and described contact pin upper end is connected with the pin holes on described cable molded plug, and the pin holes in described contact pin lower end and immersible pump is electrically connected.
Preferably, on described cable adapter, be provided with positioning boss.
Preferably, the quantity of described contact pin is three.
Submerged pump cable sealing structure of the present invention is reasonable in design, simple in structure, is sealed and is reached good sealing effectiveness, simultaneously installation, convenient for production by two-stage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further.
Accompanying drawing 1 is sealed structural representation of the present invention.
Accompanying drawing 2 is cable adapter schematic diagram of the present invention.
embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2, submerged pump cable sealing structure of the present invention is mainly used in electric connection and the sealing of motor in submersible pump cable line and immersible pump, comprise compressing tablet 1, cable molded plug 2, cable adapter 3 and housing 4, described housing 4 is immersible pump cast iron housing, on described housing, be formed with installing hole 5, cable adapter 3 is arranged in described installing hole 5, and realize sealant pouring and sealing and realize the first seal, when compressing tablet 1 compresses cable molded plug 2, cable molded plug 2 rubber deformations form the second seal, two-stage sealing, sealing grade is high.
As shown in Figure 2, cable adapter 3 is media that cable molded plug 2 and motor for submerged pump are electrically connected, be placed in the below of described cable molded plug 2, in described cable adapter 3, be provided with three contact pins 31, three contact pins are uniformly distributed with spacing at a certain angle, expose at contact pin two ends, upper end is connected with the pin holes of cable molded plug 2, lower end is connected with the motor down-lead pin holes of immersible pump, on cable adapter 3, be also provided with positioning boss 32, prevent error damage contact pin, correspondingly, cable molded plug 2 relevant positions are provided with location hole.
In conjunction with as shown in Figure 1, cable adapter 2 is fixed in housing installing hole by screw thread or seam step, is forming the first seal by encapsulating.
As shown in Figure 1, described cable mold pressing joint 2 has elastomeric material to make, extend partially in described installing hole 5, described compressing tablet 1 is fixedly installed on described cable mold pressing joint 2, when described compressing tablet compresses, described cable mold pressing joint 2 distortion, and form the second seal with the installing hole inwall of described housing.
During installation, first alignment pin, install cable adapter 3, and sealant pouring and sealing fixes, then aim at positioning boss 32, cable molded plug 2 is pressed in the installing hole of cast housing, compress compressing tablet, the distortion of cable molded plug is fitted on described housing, form two-stage sealing, good sealing effect, and installation, convenient for production.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
