Technical Field

[0001] The utility model relates to the field of automotive electronics, in particular to a motor controller busbar connection system. Background Art

[0002] Typically, when connecting a motor controller to a busbar, the busbar is bolted to the motor controller.

[0015] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0016] The utility model discloses a motor controller busbar connection system for connecting a busbar 4 with a motor controller. Figure 1 and Figure 2 As shown, the system includes a busbar interface 1 formed on the motor controller housing, so that the busbar 4 passes through the busbar interface 1, so that the terminal 41 at the front end of the busbar 4 is electrically connected to the motor controller.

[0017] The connector also includes a connector that can connect the busbar 4 to the motor controller stably and reliably. The connector has a tail cover 21 and a shell 22, both of which have through holes that can allow the busbar 4 to pass through. The tail cover 21 and the shell 22 are generally detachably fixed, such as Figure 1 As shown, the two are fixed by snapping, that is, the tail cover 21 has a tail cover snap-in, and the shell 22 has a shell buckle.

[0018] The housing 22 has a front protrusion 23 and a rear protrusion 26. The front protrusion 23 extends toward the motor controller housing, while the rear protrusion 26 extends away from the motor controller housing. Both protrusions are formed on the periphery of the through-hole. In other words, both the front protrusion 23 and the rear protrusion 26 have through-holes for the busbar 4 to pass through, providing a certain degree of fixation, at least to prevent the busbar 4 from swinging. A reinforcing rib 27 is provided between the rear protrusion 26 and the housing 22.

[0019] A first connecting device is provided on the motor controller housing, and a second connecting device is provided on the outer shell 22. The first connecting device and the second connecting device are removably fixedly connected. Preferably, the first connecting device is a snap-on piece 12, and the second connecting device is a snap-on head 25. The snap-on piece 12 and the snap-on head 25 engage to secure the outer shell 22 to the motor controller housing.

[0020] Furthermore, the outer periphery of the front protrusion 23 has an external thread, such as Figure 3 and Figure 4 As shown, a swivel 11 is provided within the busbar interface 1. This swivel 11 is rotatably mounted coaxially with the busbar interface 1 and has internal threads. The swivel 11 is mounted within the busbar interface 1 via a bearing. After the busbar 4 passes through the housing 22 and the terminal 41 extends into the motor controller housing, the swivel 11 is rotated to mate the internal threads with the external threads of the protrusion 23. The entire housing 22 is then pulled inward and secured, firmly fastening the housing 22 to the motor controller housing.

[0021] In a preferred embodiment, the rotating ring 11 will extend a portion of the wall surface of the motor controller housing to facilitate the worker's rotation operation. The outer wall surface of the extended portion of the rotating ring 11 has a structure such as a groove or the like for easy rotation. More preferably, the rotating ring 11 can be rotated by the auxiliary dial 5, such as Figure 4 As shown, the auxiliary dial has a drive mechanism, such as a gear or rack, that engages with corresponding positions on the rotating ring 11 to drive the ring 11 to rotate. The auxiliary dial is exposed on the motor controller housing for manual operation. In this embodiment, the rotating ring 11 has a portion that engages with the drive mechanism. The drive mechanism can be the surface of the auxiliary dial itself, for example, by providing a high-friction outer surface such as rubber to directly drive the movement of the rotating ring 11.

[0022] The aforementioned snap tabs 12 and snap heads 25, along with the internal and external threads, provide a better secure connection between the housing 22 and the motor controller housing, particularly preventing wiggle. Furthermore, by rotating the swivel 11, the length of the busbar 4 extending into the motor controller housing can be adjusted within a certain range, providing a more precise connection position. Furthermore, this structure prevents the busbar 4 from losing its connection to the motor controller if it is pulled.

[0023] Preferably, the connector further comprises a shielding ring 24, which is arranged outside the front protrusion 23. A sealing ring 3 is provided between the tail cover 21 and the housing 22, which is sleeved outside the busbar 4.

[0024] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
