the utility model provides a stealthily dirty pump is with sealed cable conductor with protective structure, includes rubber sleeve, cable conductor, pump body connecting wire and cast iron gland, all is equipped with the sinle silk in cable conductor, the pump body connecting wire to through the core connection, be equipped with the copper sheathing between the sinle silk, the sinle silk is fixed on the copper sheathing, the both ends of copper sheathing are equipped with binding off structure, the middle section of rubber sleeve is equipped with annular flange, and annular flange falls into two parts with the rubber sleeve, and the one end that the rubber sleeve is connected with pump body connecting wire is divided into constriction portion one and spacing portion, and the rubber sleeve is divided into supporting part and constriction portion two with cable connection's one end, and annular flange, spacing portion, the ladder configuration of constriction portion, diameter progressively diminish, constriction portion two, supporting part, annular flange ladder configuration, diameter progressively increase.

Preferably, one side of the annular flange is provided with a boss, and the boss extends along the annular flange to form an annular structure.

This setting has increased the inseparable degree of rubber sleeve with pump body coupling, has increased the leakproofness.

Preferably, the cast iron gland is sleeved on the rubber sleeve, one end of the cast iron gland is in contact with the annular flange, and the other end of the cast iron gland is in contact with the second contraction part.

This setting is convenient for form the protection to the rubber sleeve that exposes outside, simultaneously through the contact with the rubber sleeve, accomplishes the protection to the core junction, prevents that the sinle silk from dragging the fracture.

Preferably, a salient point is arranged at one end of the cast iron gland, which is in contact with the second contraction part.

This setting increases the frictional force between cast iron briquetting and the rubber sleeve for the difficult slip of cast iron briquetting, convenient to use.

Preferably, the cast iron gland is provided with a fixing hole.

This setting is convenient for accomplish the fixed connection with the pump body through the effect of fixed orifices.

The utility model has the advantages that: convenient to use, easy operation, compact structure, the cable of being convenient for is connected, is fixed with pump body connecting wire, and sinle silk joint strength is high, and stability is good, and liquid such as water can not get into the inside of cable simultaneously, and whole leakproofness is good, be suitable for with the use under the multiple environment, and external structure intensity is high simultaneously, is difficult for calculating bad during the installation, receives external environment influence for a short time, has practicality and the universality of use.
