Technical Field

[0001] This utility model belongs to the field of vehicle drive motor technology. Specifically, this utility model relates to a motor wiring device with a split structure. Background Technology

[0002] In existing technologies, motor terminal blocks suffer from poor wiring compatibility, fixed terminal positions, and low versatility; installation and adjustment are difficult, and positional deviations cannot be fine-tuned during installation; after wiring, cables are prone to stress concentration, and joints loosen under long-term vibration, leading to poor contact; protection performance is insufficient, lacking dustproof and splashproof structures, allowing dust or moisture to enter the wiring area, causing electrical corrosion and shortening service life; structural strength is weak, with no reinforced base design, making it prone to deformation under load or vibration, affecting wiring stability; previous terminal blocks were all integral designs, with complex structures leading to high manufacturing costs; therefore, there is an urgent need for a split terminal block that combines wiring adjustment, multi-scenario installation, protection and strength, and flexible installation.

[0003] Chinese patent CN210041527U disclosed a motor terminal block on February 7, 2020, including a terminal block body. The terminal block body has a first mounting groove, a second mounting groove, and a third mounting groove arranged side by side for mounting copper busbars. Each of the first, second, and third mounting grooves has a positioning structure that cooperates with the copper busbar. However, the integrated structure results in higher manufacturing costs. Utility Model Content

[0004] The present invention aims to provide a structurally separate motor wiring device that reduces manufacturing costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A modular motor wiring device includes a terminal block, a copper busbar inside the terminal block, and a steel sleeve on the copper busbar.

[0006] The terminal block includes an injection-molded body, a boss, and a base. The boss is located at the bottom of the injection-molded body, and the base is located at the bottom of the boss.

[0007] The copper busbar is bent into a first connecting plate and a second connecting plate. The top of the injection molding body is provided with a first groove that mates with the first connecting plate, and the inside of the injection molding body is provided with a second groove that mates with the second connecting plate.

[0008] The steel sleeve includes a first steel sleeve and a second steel sleeve, which are respectively located at both ends of the copper busbar.

[0009] The first connecting plate is provided with a first connecting hole, and the second connecting plate is provided with a second connecting hole.

[0010] The top of the injection molding body is provided with a first positioning hole that mates with the first steel sleeve, and the base is provided with a second positioning hole that mates with the second steel sleeve.

[0011] The copper busbar is an L-shaped plate, the injection-molded body is a square plate, the boss is square, and the base is a square block.

[0012] The injection-molded body is provided with mounting holes on all four sides.

[0013] The second connecting plate has multiple sets of protrusions.

[0014] The outer walls of the first and second steel sleeves are provided with knurled threads.

[0015] The technical advantages of this invention are as follows: By dividing the motor terminal block into an injection-molded body, a boss, and a base, and bending the copper busbar into a first connecting plate and a second connecting plate, the top of the injection-molded body has a first groove that mates with the first connecting plate, and the interior of the injection-molded body has a second groove that mates with the second connecting plate. The copper busbar is placed inside the injection-molded body. The top of the injection-molded body has a first positioning hole that mates with a first steel sleeve, and the base has a second positioning hole that mates with the second steel sleeve. By designing the entire wiring device into multiple components, the complexity of the mold and the cost of production can be reduced. Multiple sets of protrusions on the copper busbar further prevent it from falling out after being inserted into the injection-molded body. Attached Figure Description

The boss 5 and the base 6 are fixedly connected to the injection-molded body 4 and can be sealed with adhesive through the contact surface. The boss 5 is used to embed into the positioning groove of the motor mounting surface, and after the countersunk screws are tightened, it can achieve a fixed position without deviation.

[0024] like Figure 3 As shown, the copper busbar 2 is bent into a first connecting plate 7 and a second connecting plate 8. The top of the injection molding body 4 has a first groove 9 that mates with the first connecting plate 7, and the inside of the injection molding body 4 has a second groove 10 that mates with the second connecting plate 8. The copper busbar 2 is bent into a first connecting plate 7 and a second connecting plate 8. The first connecting plate 7 is positioned within the first groove 9 on the top of the injection molding body 4, and the second connecting plate 8 is inserted into the second groove 10 inside the injection molding body 4. The first groove 9 is used to install the first connecting plate 7, and the second groove 10 is used to insert the second connecting plate.

The top of the injection molding body 4 is provided with the first positioning hole 15, the first steel sleeve 11 passes through the first positioning hole 15, and the second steel sleeve 12 passes through the second positioning hole 15.

[0028] The copper busbar 2 is an L-shaped plate, the injection molding body 4 is a square plate, the boss 5 is square, and the base 6 is a square block. The copper busbar 2 is bent into an L-shape. The first connecting plate 7 is set on the top of the injection molding body 4, and the second connecting plate 8 is inserted into the injection molding body 4. One side of the second connecting plate 8 contacts one side of the base 6.

[0029] The injection-molded body 4 has mounting holes 17 on all four sides. The mounting holes 17 are for bolt and motor connection, which can be adapted to standardized installation scenarios, simplify the installation process and improve installation efficiency.

[0030] The second connecting plate 8 is provided with multiple sets of protrusions 18. The copper busbar 2 is provided with multiple sets of protrusions 18 to further prevent the copper busbar 2 from falling off after being inserted into the injection molding body 4, and to increase airtightness and improve the protection level.

[0031] The outer walls of the first steel sleeve 11 and the second steel sleeve 12 are provided with knurled threads.
