Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a brushless motor phase wire connection box. Background Technology

[0002] A brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. Because a brushless DC motor operates in a self-controlled manner, it does not require an additional starting winding on the rotor like a synchronous motor that starts under heavy load with frequency conversion speed regulation, nor does it experience oscillation or loss of synchronism when the load changes abruptly.

[0003] In the field of brushless motors, with the continuous development of technology and the increasing expansion of application scenarios, the problems exposed by the traditional phase wire connection method have become more and more prominent. From the perspective of installation, the traditional connection method requires professional technicians to connect multiple phase wires to the motor's internal wires one by one. This not only requires operators to have solid professional knowledge, but also requires a lot of time to spend on tedious wiring and debugging. It is time-consuming, labor-intensive, and inefficient. In addition, connection failures may occur due to operational errors during the wiring process, further extending the installation cycle. Utility Model Content

[0007] Preferably, the protective component includes a protective shell, and the wiring component and the fixing component are both located inside the protective shell. A cover plate is detachably installed on one side of the protective shell by bolts. A sealing ring is provided between the cover plate and the protective shell. Multiple wire holes are provided on one side of the protective shell, and the wire holes correspond one-to-one with the fixing bracket and the wiring groove.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-5 As shown, this utility model provides a brushless motor phase wire connection box, including a wiring assembly 2 and a protective assembly 3. The wiring assembly 2 includes a wiring board 201, on which multiple wiring slots 202 are fixedly installed. Conductive copper sheets 205 are fixedly installed on one side of each of the multiple wiring slots 202. First screws 203 are threaded into each of the multiple wiring slots 202, and wire clamping plates 204 are fixedly installed at one end of each of the multiple first screws 203. The wiring board 201 is equipped with a number of fixing components 4 equal to the number of wiring slots 202. The wiring board 201 can be bolted to the brushless motor housing 1, so that the internal wires of the brushless motor are connected to the conductive copper sheets 205 in the wiring slots 202 through wires (this operation is only required during the initial installation; subsequent installations will not be necessary). Without damage or removal, and without needing to reinstall the terminal block 201 for future phase wire replacements and other connections, when it is necessary to connect the phase wire to the brushless motor, the terminal of the phase wire can be inserted into the corresponding terminal slot 202. Then, using a screwdriver, the first screw 203 is rotated through the cross slot at one end. The first screw 203 drives the wire clamping plate 204 to move towards the conductive copper plate 205 in the terminal slot 202 until the phase wire connector is pressed tightly onto the conductive copper plate 205, thus completing the phase wire connection of the brushless motor. Compared with the traditional installation method of connecting multiple phase wires to the motor's internal wires one by one, this device is convenient and quick. By setting up modular components, the installation difficulty is greatly reduced, the installation cycle is effectively shortened, and work efficiency is greatly improved.

[0020] Each of the multiple fixing components 4 includes a fixing frame 401, which is fixedly mounted on the terminal block 201. The fixing frame 401 corresponds one-to-one with the terminal slot 202. Each fixing frame 401 has a clamping block 402 slidably installed inside it. The clamping block 402 and one side of the fixing frame 401 are provided with V-shaped grooves to facilitate clamping and fixing phase wires of different thicknesses. Each fixing frame 401 has a second screw 403 threaded into one side. One end of the second screw 403 is rotatably connected to one side of the corresponding clamping block 402. When the phase wire is connected, the phase wire passes through the corresponding fixing frame 401. After the phase wire is connected, a screwdriver can be used to drive the second screw 403 to rotate through the cross groove at one end of the second screw 403. The second screw 403 drives the clamping block 402 to slide inside the fixing frame 401 to clamp and fix the phase wire. This can prevent the wire harness from accidentally coming off due to external forces such as pulling or collision during motor operation, which would affect the normal operation of the motor.

[0021] The protective component 3 includes a protective shell 301, and the wiring component 2 and the fixing component 4 are both located inside the protective shell 301. A cover plate 302 is detachably installed on one side of the protective shell 301 by bolts. A sealing ring 303 is provided between the cover plate 302 and the protective shell 301. Multiple vertically distributed wire-passing holes 3011 are provided on one side of the protective shell 301, and the wire-passing holes 3011 correspond one-to-one with the fixing bracket 401 and the wiring groove 202. Each of the multiple wire-passing holes 3011 is fitted with a waterproof sealing sleeve 304. The protective shell 301 can be installed onto the brushless motor housing 1 by bolts. The wiring component 2 and the fixing component 4 are both located inside the protective shell 301. The contact surface between the protective shell 301 and the brushless motor housing 1 is provided with... The sealing ring 303 improves the sealing performance of the protective component 3. The phase wire can be connected by passing through the wire hole 3011 and the waterproof sealing sleeve 304 on the protective shell 301. The waterproof sealing sleeve 304 prevents dust and water from entering the protective shell 301 through the wire hole 3011. The inner diameter of the selected waterproof sealing sleeve 304 is the same as the diameter of the phase wire to be connected. After the phase wire is connected, the cover plate 302 can be installed on the protective shell 301 by bolts, and the sealing ring 303 is set between the cover plate 302 and the protective shell 301 to seal the protective shell 301. The protective component 3 can protect the connection of the line and play a role in dust prevention and waterproofing.

[0022] Working principle: In use, the terminal block 201 is first bolted onto the brushless motor housing 1, connecting the internal wires of the brushless motor to the conductive copper sheet 205 in the wiring slot 202. The protective housing 301 is then bolted onto the brushless motor housing 1. The wiring assembly 2 and the fixing assembly 4 are both located inside the protective housing 301. A sealing ring 303 is provided on the contact surface between the protective housing 301 and the brushless motor housing 1. Next, the phase wire is passed through the wire hole 3011 and the waterproof sealing sleeve 304 on the protective housing 301, and then through the corresponding fixing bracket 401. Insert the phase wire terminal into the corresponding terminal slot 202. Then, use a screwdriver to drive the first screw 203 to rotate through the cross slot at one end of the first screw 203. The first screw 203 drives the wire clamping plate 204 to move towards the conductive copper sheet 205 in the terminal slot 202 until the phase wire connector is pressed tightly onto the conductive copper sheet 205, thus completing the phase wire connection of the brushless motor. Compared with the traditional installation method of connecting multiple phase wires to the motor's internal wires one by one, this device is convenient and quick. By setting up modular components, the installation difficulty is greatly reduced, the installation cycle is effectively shortened, and the work efficiency is greatly improved.

[0023] Then, using a screwdriver, the second screw 403 is rotated through the cross groove at one end of the second screw 403. The second screw 403 causes the clamping block 402 to slide within the fixing frame 401, clamping and fixing the phase wire. This prevents the wire harness from accidentally coming off due to external forces such as pulling or collision during motor operation, thus affecting the normal operation of the motor.

[0024] Finally, the cover plate 302 is installed onto the protective shell 301 with bolts, and a sealing ring 303 is provided between the cover plate 302 and the protective shell 301 to seal the protective shell 301. The protective component 3 can protect the connection of the circuit and can play a role in dust prevention and waterproofing.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
