Description

Water pump motor junction box Technical Field The utility model belongs to the technical field of water pumps, and relates to a water pump motor, in particular to a water pump motor junction box. Background The water pump motor terminal box is generally installed at the motor casing top, wherein, runs through on the motor casing lateral wall and is equipped with the through-hole, has seted up the through wires hole on the terminal box diapire, and motor coil lead wire passes through-hole and through wires hole in proper order and gets into the terminal box. The structure of the existing junction box is as a motor junction box disclosed in China patent library (application number: 201420255539.7) comprises a cable connector, a matched box cover and a box seat, wherein one side wall of the box seat is used for installing the installation side wall of the cable connector, the cable connector is characterized in that the installation side wall is integrally provided with a vertical installation seat, the outer side face of the vertical installation seat is a vertical plane, the cable connector is horizontally installed on the vertical plane of the vertical installation seat, the box cover comprises a top plate and a connecting part which extends along the peripheral edge of the top plate and is used for being connected with the box seat, and the peripheral edge of the top plate and the connecting part form a reinforcing rib in a circular arc transition mode. In the junction box, the cable joint not only enables the electric wires in the junction box to extend out, but also forms a seal with the electric wires, thereby playing a role in water resistance. When in actual use, the probability that the sealing is not completely effective due to improper operation exists, and at the moment, a small part of water can permeate into the box seat through the sealing failure position and enter the machine shell to influence the normal operation of the motor. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides a water pump motor junction box capable of improving the operation reliability of a motor. The water pump motor junction box is horizontally arranged at the top of the shell and comprises a box body arranged on the shell and a box cover arranged on the box body, a wire passing hole used for communicating an inner cavity of the shell is formed in the bottom of the box body, a threaded hole is formed in the side wall of the box body in a penetrating mode, a cable connector is arranged outside the box body, one end of the cable connector is a threaded end, the threaded end is screwed into the threaded hole, the inner side of the bottom wall of the box body is provided with a groove, the periphery of the groove is sealed, a notch of the groove is arranged upwards, the threaded end extends into the inner cavity of the box body, downward projections of the portion of the threaded end, which is located in the inner cavity of the box body, completely fall into the groove, the groove and the wire passing hole are staggered, a drain hole is formed in the bottom wall of the groove vertically, a water collecting pipe made of transparent materials is vertically arranged below the box body, the lower end of the water collecting pipe is sealed, the upper end of the water collecting pipe is detachably and fixedly connected with the box body in a sealing mode, and the drain hole is opposite to and communicated with the inner hole of the water collecting pipe. When the motor is used, water penetrating into the box body through the cable connector is firstly gathered in the groove under the action of gravity, and the groove and the wire passing holes are staggered to ensure that the groove and the wire passing holes are not communicated, so that the water is effectively prevented from directly entering the motor through the wire passing holes, the motor can be protected to a certain extent, the service life is prolonged, and the working reliability of the motor is improved. Because the drain hole communicates the collector pipe hole, and the collector pipe is made by transparent material, whether have water to judge the terminal box leakage state through observing the collector pipe like this, convenient follow-up maintenance.
