reference numerals: 1. a motor terminal; 2. a control end; 3. an outgoing line; 4. a connecting section; 5. a fastener; 6. a countersunk washer; 7. a screw; 8. a seal ring; 9. and (7) heat-shrinkable tubes.

Detailed Description

The invention will be further described in the following with specific embodiments in conjunction with the drawings, see fig. 1:

the utility model provides a connection structure for pump, the upper end of pump is motor end 1, and the lower extreme is control end 2, the pump still includes the middle part and holds linkage segment 4 of lead-out wire 3, motor end 1, 2 covers of control end are established on linkage segment 4, linkage segment 4 through the fastener 5 of a plurality of circumference settings respectively with motor end 1 and 2 fixed connection of control end.

The utility model discloses a segmentation connection structure, the frame length of control end 2 and the length of reserving lead-out wire 3 all are less than current well submerged motor pump, and segmentation connection structure assembly is more convenient, also can not cause lead-out wire 3 to crush during the assembly or broken skin.

The fastener 5 has the following specific structure: the screw fixing device comprises a countersunk washer 6 and a screw 7 penetrating through the countersunk washer 6, wherein the screw 7 is fixedly connected with the connecting section 4 and the motor end 1 or the connecting section 4 and the control end 2, and the screw 7 penetrates through the countersunk washer 6 and then is in threaded connection with the connecting section 4. The screw 7 is preferably a cross-recessed pan head screw.
