Description

Motor controller connection structure

Technical Field

The utility model relates to the field of motors, in particular to a motor controller connecting structure.

Background

In the field of fans, connection of high-voltage circuits is realized, a common scheme is wire harness connection, welding fixation or screw locking is needed when two ends of a wire harness are fixed, material cost and time cost are high, operation difficulty is increased due to space limitation and the like when the fan is used, and finally the wire harness is required to be folded; other universal connectors may be used, but require a larger space to be reserved, and are not suitable for use in situations where installation space is limited.

If the fan motor is integrated with the controller, the space can be saved, wiring is reduced, the structure is simple, the installation is convenient, the circuit connection function is realized in a limited space, the connection of high-voltage wires is omitted, and the cost is reduced; after the stator and the control board are preassembled, all terminals are simultaneously plugged into the three-phase interface during assembly, so that the assembly operation is simplified, and the installation time is saved.

Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

Example 1

Referring to fig. 1 and 2, a motor controller connection structure includes a male member 1 and a female member 2, wherein the female member 2 is hollow, an elastic sheet 21 is provided on an inner wall of the female member 2, a mounting ear 22 is provided on a mounting end of the female member 2, an insertion end 11 of the male member 1 can be inserted into the female member 2, and a bump 111 is provided at a contact position between the male member 1 and the elastic sheet 21 after the male member 2 is inserted. When the male part 1 is inserted into the female part 2, the elastic sheet 21 is extruded to deform, and the elastic sheet 21 extrudes the male part 1 due to elastic force, so that the male part 1 and the female part 2 are in close contact, and the conductivity stability is improved.

Preferably, the elastic sheet 21 on the inner wall of the female member 2 is provided with a protrusion 211, and the protrusion 211 is matched with the protrusion 111, so that the extrusion elasticity is further improved, and the contact conductivity stability of the male member 1 and the female member 2 is improved; the contact position of the spring piece 21 and the bump 111 can be set as a groove matched with the bump 111, so that the contact conductivity stability can be further improved while the contact is prevented from sliding off.

Preferably, the number of the mounting lugs 22 is two and the mounting lugs 22 are oppositely arranged, and the female part 2 is mounted on the control panel through the mounting lugs 22 and can be firmer and more reliable through soldering or bending; the number of the elastic pieces 21 is two and oppositely arranged, and when the male part 1 is inserted into the female part 2, a larger clamping force is provided by the two oppositely arranged elastic pieces 21.

Preferably, the male part 1 is provided with a terminal 12 at a portion where the female part 2 is not inserted, for connecting a wire or a signal line; the mounting end 13 of the male member 1 is provided with a ratchet 131 and a limiting block 132, the male member 1 is mounted on a motor stator through the mounting end 13, the part of the mounting end 13 provided with the ratchet 131 is completely inserted into the motor stator, and meanwhile the excessive insertion of the mounting end 13 is limited through the limiting block 132; the fixing can be further reinforced by glue filling in view of the possibility of dropping.

Preferably, the female member 2 and the male member 1 are integrally molded, the post 12 is punched from the male member 1, and the post 12 is bent toward the insertion end 11 to prevent the wire from slipping off.

Preferably, the protruding points 111 are rounded at the mating parts with the elastic pieces 21, so as to facilitate the insertion of the male member 1 into the female member 2.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
