Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to an insulating winding frame. Background Art

[0002] The stator assembly is the main component of the motor, and the insulating winding frame is the main component of the stator assembly. The insulating winding frame is mainly used for winding enameled wire. The enameled wire needs to be stripped before it can be connected to the conductive lead for conduction. In some cases, during the motor assembly process, after the enameled wire is installed on the stator wire frame, the paint needs to be manually cut off at the end or a specific position to connect the lead. Therefore, using a manual tool to remove the paint will affect the assembly efficiency of the stator wire frame. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides an insulating winding frame which has a simple structure and is convenient for removing the coating of enameled wires.

[0004] The technical problem to be solved by the utility model is achieved through the following technical means: an insulating winding skeleton, comprising a main body and two piercing terminals, slots are arranged on both sides of the upper part of the main body, a column is vertically arranged in the middle of the bottom of the slot, wire passing grooves are vertically arranged on the tops of the front and rear sides of the slot, the height of the wire passing grooves is less than the height of the slot, the bottom of the piercing terminal is adapted to the slot, a through-hole corresponding to the column is arranged in the middle of the bottom of the piercing terminal, piercing grooves are arranged on the front and rear sides of the upper part of the through-hole, and the piercing grooves are communicated with the through-holes.

[0005] In the above scheme, the enameled wire can be extended from the two wire grooves in front and behind the slot, so that a part of the enameled wire will cross the slot, and the slot surface of the piercing slot of the piercing terminal is sharp to a certain extent, and the bottom of the piercing terminal can be inserted into the slot. The piercing slot can pierce and peel the part of the enameled wire that crosses, and the piercing terminal itself is conductive, so as long as the conductive lead is connected to the piercing terminal, the conductive function of the stator assembly can be realized. The utility model uses the piercing terminal to directly remove the paint skin of the enameled wire that crosses the slot in the form of insertion, eliminating the need for manual cutting and peeling with a knife, so it is more efficient and more convenient. In addition, since the utility model adds a column in the slot, when the piercing terminal is inserted, the column passes through the perforation, and the inner wall of the perforation can contact the outer wall of the column, and the friction between the two can be used to keep the piercing terminal stably limited in the slot.

[0006] In one embodiment, the top surface of the column is located between the bottom and the top of the wire trough.

[0007] In the above scheme, when the enameled wire crosses the slot, at least part of the enameled wire is located directly above the column, so that the puncture groove can cut off the paint coating of the enameled wire above the column.

[0008] In one embodiment, the overall shape of the slot is a cube.

[0009] In one embodiment, the bottom of the puncture groove is conical, and the top of the puncture groove is strip-shaped.

[0010] In the above scheme, the cone shape of the bottom of the puncture groove has a guiding effect, which facilitates the introduction of the enameled wire into the puncture groove.

[0011] In one embodiment, a wire hole for connecting to an external conductive lead is provided on the upper portion of the piercing terminal.

[0012] In one embodiment, upper and lower layers of positioning bumps are provided on both left and right sides of the bottom of the piercing terminal.

[0013] In the above solution, the positioning protrusion cooperates with the inner side wall of the slot and is used to clamp the side wall of the slot when the piercing terminal is inserted into the slot to prevent the piercing terminal from easily falling out.

[0014] In one embodiment, a wire winding portion is provided at the front portion of the main body. BRIEF DESCRIPTION OF THE DRAWINGS
