Detailed Description

The present invention will be described in further detail with reference to examples.

The first embodiment is as follows:

this embodiment provides a lead connection structure of water pump motor, as shown in fig. 1 to 8, including installing stator enameled wire 1 in the motor, installing in the capacitance box 2 and the lead wire 3 of motor outer wall, the tip of stator enameled wire 1 even has female terminal 4 (for puncturing between female terminal 4 and the stator enameled wire 1 and being connected, namely after stator enameled wire 1 impresses female terminal 4, female terminal 4 can hang the coating on the stator enameled wire 1 to make contact between female terminal 4 and the stator enameled wire 1 be connected electrically), the one end of lead wire 3 is passed capacitance box 2 and is gone into in the motor and the joint has a male terminal 5 with female terminal 4 matched with, the other end of lead wire 3 is used for being connected with electric capacity or external power source in the capacitance box 2 electricity.

In this embodiment, the capacitor box 2 includes a base 6 connected to an outer wall of the motor and a mounting box 7 connected to the base 6, the mounting box 7 is used for mounting a capacitor, a first wire outlet 8 is formed in a side wall of the base 6, as shown in fig. 7, the first wire outlet 8 of this embodiment is a large hole, all the leads 3 pass through the first wire outlet 8, a threading hole 9 is formed in a bottom surface of the base 6, wire pressing grooves 10 are formed in the bottom surface of the base 6 and the bottom surface of the mounting box 7, the two wire pressing grooves 10 are arranged oppositely and vertically corresponding to each other, and the wire pressing groove 10 on the base 6 is located between the threading hole 9 and the first wire outlet 8; the joint has outlet nozzle 11 on outlet hole 8, because the motor of this embodiment is the water pump motor, and is higher to the requirement of leakproofness, and the gap between outlet hole 8 and the lead wire 3 is great, so adopt to make outlet nozzle 11 by the rubber material and play sealed effect, outlet nozzle 11 can also further stabilize lead wire 3 simultaneously.
