Abstract
The utility model designs a kind of mini submersible sewage pump long cable section of ingoing line structure of improvement, comprise cable, connector cover, compression plug screw, cable seal packing ring, it is characterized in that: cable is placed in connector cover, on the boss in portion in the cable, cover has cable seal packing ring, and the compression plug screw be sleeved on cable is conflicted and is threaded with connector cover on cable seal packing ring.Described cable is made up of cable, cable connection section, coated section of cable, cable seal section, cable core section between cable and cable connection section is connected by soldering, cable and cable connection section junction are provided with cable seal section, cable seal section forms a boss, the utility model has the advantages that cable seal section and cable sulfide by the cable in novel cable incoming line structure, even if on-site cable ftractures, and can not enter motor.Improve burn-down of electric motor situation largely.
Description
Technical field
The utility model relates to a kind of mini submersible sewage pump long cable section of ingoing line structure of improvement.
Background technology
Existing mini submersible sewage pump long cable section of ingoing line hermetically-sealed construction is as accompanying drawing 1, and incoming seal structure is made up of cable 11, connector cover 12, cable sealing ring 13, compression plug screw 14, cable seal packing ring 15.During assembling, part 14,15,13 is inserted in 11, more wholely fits in 12, finally with spanner fastening 14.This structure has three water leakage points, part 11 and 12 place, part 11 and 13 place, part 11 itself.Easily there is cable water inlet when therefore using, finally enter into motor, the accident of burn-down of electric motor occurs, needs to carry out architecture advances to it.
Summary of the invention
The purpose of this utility model be solve prior art middle-size and small-size proof submersible sand discharging pump long cable section of ingoing line hermetically-sealed construction parts between there is the problem that water leaks, a kind of mini submersible sewage pump long cable section of ingoing line structure of improvement is provided.The utility model designs a kind of mini submersible sewage pump long cable section of ingoing line structure of improvement, comprise cable, connector cover, compression plug screw, cable seal packing ring, it is characterized in that: cable is placed in connector cover, on the boss in portion in the cable, cover has cable seal packing ring, and the compression plug screw be sleeved on cable is conflicted and is threaded with connector cover on cable seal packing ring.Described cable is made up of cable, cable connection section, coated section of cable, cable seal section, cable core section between cable and cable connection section is connected by soldering, cable and cable connection section junction are provided with cable seal section, cable seal section forms a boss, and the cable outer layer of cable seal drop cable side is provided with coated section of cable.Cable seal section is the boss that insulating material is formed, and coated section of cable is for being coated on the insulating barrier on cable.The utility model has the advantages that cable seal section and cable sulfide by the cable in novel cable incoming line structure, and the cable core of cable and cable connection section is linked together by soldering.Compare old structure and lacked two leakage points, even if on-site cable cracking, water only can arrive cable seal section along cable core, and because this section does vulcanizing treatment, water only rests on herein, and can not enter motor.Improve burn-down of electric motor situation largely.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is elaborated.
Accompanying drawing 1 is existing structure schematic diagram; Accompanying drawing 2 is structural representation of the present utility model; Accompanying drawing 3 is construction of cable schematic diagram of the present utility model.
Embodiment
The mini submersible sewage pump long cable section of ingoing line structure of a kind of improvement in figure, comprise cable 1, connector cover 2, compress plug screw 3, cable seal packing ring 4, it is characterized in that: cable is placed in connector cover, on the boss in portion in the cable, cover has cable seal packing ring, and the compression plug screw be sleeved on cable is conflicted and is threaded with connector cover on cable seal packing ring.Described cable is made up of cable 1, cable connection section 5, coated section 6, cable, cable seal section 7, cable core section 9 between cable and cable connection section is connected by soldering, cable and cable connection section junction are provided with cable seal section, cable seal section forms a boss 8, and the cable outer layer of cable seal drop cable side is provided with coated section of cable.Cable seal section is the boss that insulating material is formed, and coated section of cable is for being coated on the insulating barrier on cable.
Because cable seal section and cable sulfide by the cable in novel cable incoming line structure, and cable and cable connection section are linked together by soldering.Comparing old structure and lacked two leakage points, only there is a leakage point in this structure, cable and cable connection segment place.Even and if on-site cable ftractures, water only can arrive cable seal section along cable core, and because this section has done vulcanizing treatment, water only rests on herein, and can not enter motor.Improve burn-down of electric motor situation largely.
