Description

Technical Field

[0001] This utility model relates to the field of wiring structure technology, specifically a wiring structure for an automotive motor. Background Technology

[0002] Terminal block inserts in automotive motor drive assemblies are important components that connect the motor to other electrical components. They ensure stable current transmission and normal motor operation. These inserts are usually embedded in the terminal block and, through specific structural design, achieve a tight fit with the motor terminals or other electrical connection components.

[0003] A terminal block with publication number CN212648596U includes a base plate, characterized in that: a conductive nut and a signal connector are provided inside the base plate; the conductive nut has an upper wiring screw hole and a lower wiring screw hole formed on the top and bottom surfaces of the base plate, respectively; the signal connector has an upper signal interface and a lower signal interface formed on the top and bottom surfaces of the base plate, respectively; the conductive nut inside the base plate is used for connecting motor terminals; first, spring washers and flat washers are inserted into screws, then terminals are inserted into screws, and a handheld pneumatic screwdriver is used to screw the screws into the conductive nut to fix the terminals in place;

[0004] The wiring method has the following problems: 1. Due to the drag force of the three-phase wires of the motor, the screw is not guided when it is inserted into the conductive nut, which makes it easy to tilt, making assembly difficult and time-consuming. 2. When the wiring terminal is locked, screws, spring washers and flat washers are required. There are many assembly parts, and the washers are easy to fall into the motor, causing quality accidents. In order to solve the above problems, this application designs a wiring structure for vehicle motors. Utility Model Content

[0009] Furthermore, an improvement of this utility model is that the screw, the top hole, and the side hole are all fixed by injection molding.

[0010] To prevent the screw from protruding too far from the substrate and thus avoid electric shock, this invention is improved so that the length of the screw located on the side does not exceed the edge of the substrate.

[0011] To prevent short circuits between two adjacent copper terminals, this invention includes an isolation plate fixed between each of the two adjacent copper terminals on the substrate.

[0012] To facilitate installation while enhancing the fixation of the terminals, this utility model is improved by setting the fixing nut as a serrated external hexagonal flange nut.

[0013] To make the wiring copper plate more secure and prevent it from shaking, the present invention is improved by providing slots on the bottom and side walls of the wiring copper plate.

[0024] Please see Figure 1-4 A wiring structure for an automotive motor includes a base plate 1, on which a plurality of wiring copper plates 2 are fixed. The top of the wiring copper plate 2 is provided with a top hole 3, and the side wall of the wiring copper plate 2 is provided with a side hole 4. Screws 5 are fixed on both the top hole 3 and the side hole 4. Terminals 6 are sleeved on the screws 5, and fixing nuts 7 are threaded onto the screws 5.

[0025] In this structure, the terminal 6 with the connecting wire is sleeved and hung on the screw 5. This can counteract the downward drag force brought by the connecting wire, making installation convenient. Then, with the help of external tools, the fixing nut 7 is threaded onto the screw 5, and the fixing nut 7 is rotated continuously to move it closer to the terminal 6 along the screw 5 and make contact to fix it, thus completing the installation of the terminal 6.

[0026] Furthermore, in this embodiment, the screw 5 is fixed to the top hole 3 and the side hole 4 by injection molding.

[0027] In actual use, it was found that the screw 5 located on the side was too long and exceeded the edge of the substrate 1, which could easily cause accidental contact and electric shock. In order to avoid the above problem, in this embodiment, the length of the screw 5 located on the side does not exceed the edge of the substrate 1.

[0028] In actual use, it was found that the terminals 6 connected on two adjacent copper wiring plates 2 may come into contact, causing short circuit. In order to avoid the above problem, in this embodiment, an isolation plate 8 is fixed on the substrate 1 between two adjacent copper wiring plates 2.

[0029] In actual use, it was found that in order to facilitate installation and strengthen the fixation of terminal 6, in this embodiment, the fixing nut 7 is set as a serrated external hexagonal flange nut.

[0030] In actual use, it was found that in order to make the wiring copper plate 2 more secure and prevent it from shaking, in this embodiment, the bottom end and side wall of the wiring copper plate 2 are provided with slots 9.
