Description

Technical Field

[0001] The present invention belongs to the technical field of motors, and in particular relates to a wiring assembly and a motor. Background Art

[0002] At present, high-power motors usually use terminals to pass through the terminal board to connect the motor and external conductive devices. One part of the terminal is located on the outside of the terminal board and is connected to the output end of the frequency converter cabinet; the other part is located on the inside of the terminal board and is connected to the motor lead wire. In order to ensure that the motor lead wire has sufficient insulation distance from the shell, the motor stator lead wire is usually reserved with sufficient length.

[0033] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in combination with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0034] Combination Figures 1 to 11 As shown, this embodiment provides a wiring assembly, including: a wiring column 1, a first wiring terminal 2 is provided at the first axial end of the wiring column 1, and the first wiring terminal 2 can be connected to an external wire, and a second wiring terminal 3 is provided at the second axial end of the wiring column 1, and the second wiring terminal 3 can be connected to a motor lead wire, and the second wiring terminal 3 is constructed to be able to extend outward or retract inward along the axial direction of the wiring column 1 to adjust the axial position of the second wiring terminal 3.

[0035] The wiring assembly of the disclosed embodiment is a kind of wiring assembly suitable for high-power motors to realize the connection between the motor and an external conductive device, such as the electrical connection between the motor lead wire and the output terminal of the frequency converter cabinet. By designing the second wiring terminal 3 connected to the motor lead wire as a structure that can be axially retracted, the problem in the related art that the shrink-fit stator cannot be used normally due to the inappropriate length of the motor lead wire is solved, and the axial position of the second wiring terminal can be adaptively adjusted according to the length of the motor lead wire to meet the connection requirements of motor lead wires of different lengths. The structure is simple, the cost is low, and it has high practical value.

[0036] In this embodiment, the first terminal 2 provided on the terminal post 1 can be directly used as a part of the terminal post 1, or can be installed on the terminal post 1 as an independent structure. The function of the first terminal 2 is to connect an external conductive device, and its specific structure can be reasonably selected according to actual needs.

[0037] In the first and second embodiments of the present disclosure, a hollow sleeve member 8 is provided on the second axial end of the terminal body 1, and the second terminal 3 is arranged on the hollow sleeve member 8. One axial end of the hollow sleeve member 8 is movably sleeved on the second axial end of the terminal body 1, and the hollow sleeve member 8 can extend outward or retract inward along the axial direction of the terminal body 1 to adjust the axial position of the second terminal 3.

[0038] Therefore, in the first and second embodiments of the present disclosure, by adjusting the axial length of the hollow sleeve member 8 sleeved on the terminal post body 1, the relative position of the hollow sleeve member 8 and the terminal post body 1 is changed, thereby changing the axial position of the second terminal 3, thereby achieving adaptive adjustment of the axial position of the second terminal according to the length of the motor lead wire to meet the connection requirements of motor lead wires of different lengths.

[0039] In the first embodiment of the present disclosure, one axial end of the hollow sleeve member 8 is a flap-type socket structure 21, and a locking nut 20 is provided on the outside of the hollow sleeve member. The locking nut 20 is, for example, a conical nut, and the flap-type socket structure 21 can be tightened or loosened by rotating the locking nut 20. When the flap-type socket structure 21 is loosened, the hollow sleeve member can be extended outward or retracted inward along the axial direction of the terminal body 1 to adjust the axial position of the second terminal 3.

[0040] In the wiring assembly of the first embodiment of the present invention, the end of the hollow sleeve member 8 adopts a petal-type socket structure 21 and cooperates with a locking nut 20. By loosening or tightening the locking nut 20, the petal-type socket structure 21 can be opened or closed, thereby realizing the unlocking and locking of the hollow sleeve member 8 and the terminal post 1. In the unlocked state, the hollow sleeve member 8 and the terminal post 1 are loosely matched and can slide axially to adjust the axial position of the second terminal 3. In the locked state, the hollow sleeve member 8 and the terminal post 1 are pressed tightly and the axial position is fixed, so that the motor lead wire can be connected normally, and the position of the second terminal 3 is fixed, and the motor lead wire is reliably connected.

By adjusting the thread engagement length of the first internal thread 9 and the first external thread 10, the hollow sleeve member can be extended outward or retracted inward along the axial direction of the terminal body 1 to adjust the axial position of the second terminal 3.

[0042] In the wiring assembly of the second embodiment, the hollow sleeve member 8 and the terminal column 1 are matched with each other by threads, and the axial position of the second terminal 3 can be changed by changing the screwing length of the threads, which is convenient to adjust with high precision.

[0043] In the third, fourth and fifth embodiments of the present disclosure, a hollow groove 11 is provided at the second axial end of the terminal body 1, and the hollow groove 11 extends along the axial direction of the terminal body 1 toward the first axial end of the terminal body 1. A telescopic conductive column 12 is movably inserted in the hollow groove 11, and the second terminal 3 is arranged on the telescopic conductive column 12. The telescopic conductive column 12 can be extended or retracted toward the outside of the hollow groove 11 or into the hollow groove 11 along the axis of the terminal body 1 to adjust the axial position of the second terminal 3.

[0044] Thus, in the third, fourth and fifth embodiments of the present disclosure, by adjusting the axial length of the telescopic conductive column 12 inserted in the hollow groove 11, the relative position of the hollow sleeve member 8 and the terminal body 1 is changed, thereby changing the axial position of the second terminal 3, thereby realizing adaptive adjustment of the axial position of the second terminal according to the length of the motor lead wire to meet the connection requirements of motor lead wires of different lengths.

[0045] In embodiment three, the inner wall of the hollow groove 11 is provided with a second internal thread 13, and the outer wall of the telescopic conductive column 12 is provided with a second external thread 14, and the second external thread 14 matches the second internal thread 13. By adjusting the thread engagement length of the second internal thread 13 and the second external thread 14, the telescopic conductive column 12 can be extended outward or retracted inward along the axial direction of the terminal body 1 to adjust the axial position of the second terminal 3.

[0046] In the wiring assembly of the third embodiment, the telescopic conductive column 12 and the hollow slot 11 are matched with each other by threads, and the axial position of the second wiring terminal 3 can be changed by changing the screwing length of the threads, which is convenient to adjust with high precision.

[0047] In the fourth embodiment, a limiting screw hole 15 is provided on the second axial end of the terminal body 1, and the limiting screw hole 15 penetrates into the hollow groove 11. A limiting screw 16 is provided in the limiting screw hole 15, and the limiting screw 16 can radially press and fix the telescopic conductive column 12 at any axial position in the hollow groove 11.

[0048] In the wiring assembly of the fourth embodiment, the relative position of the telescopic conductive column 12 and the hollow slot 11 is limited and fastened by the radially arranged limit screw 16, so that the motor lead wire can be normally connected, and the position of the second wiring terminal 3 is fixed, and the motor lead wire is reliably connected. At the same time, the limit screw 16 is used for limiting, and the limiting operation is convenient and safe.

[0049] Preferably, a hole or a slot for accommodating the end of the limit screw 16 is provided on the telescopic conductive column 12 to further improve the limiting effect of the limit screw 16 .

Optionally, the limiting through hole 17 can also be a blind hole or a groove opened on the inner wall of the hollow groove 11.

[0051] In the wiring assembly of the fifth embodiment, the telescopic conductive column 12 and the hollow groove 11 adopt the method of elastic protrusion 18 cooperating with the limiting through hole 17. By pressing down the elastic protrusion 18, the telescopic conductive column 12 can slide axially in the hollow groove 11, so that the axial position of the second terminal 3 changes, and the axial position of the second terminal can be adjusted adaptively according to the length of the motor lead wire to meet the connection requirements of motor lead wires of different lengths. After the elastic protrusion 18 is aligned with the limiting through hole 17, it automatically pops up, and the telescopic conductive column 12 is fastened to the hollow groove 11, and the axial position is fixed, so that the motor lead wire can be connected normally, and the position of the second terminal 3 is fixed, and the motor lead wire is connected reliably.
