Description

Technical Field

[0001] This utility model relates to a controller wiring harness, specifically a motor controller wiring harness, and belongs to the field of motor controller technology. Background Technology

[0002] The motor controller wiring harness is a key component connecting the motor controller to the motor and other related equipment. Its core function is to achieve efficient bidirectional signal and power transmission. The motor controller receives command signals from the vehicle or equipment control system and transmits them to the motor through the control signal lines in the wiring harness, driving the motor to operate according to the commands. At the same time, the motor's operating status information is collected by sensors, converted into electrical signals, and then transmitted back to the controller through the feedback lines of the wiring harness, forming a closed-loop control to ensure stable motor operation.

[0003] However, because the multiple wire harnesses of the motor controller are bundled together, they are prone to wear of the insulation layer due to mutual friction, and may even cause short circuits, which will affect the stability of signal or power transmission. In addition, the messy arrangement of the wire harnesses makes it difficult to quickly identify the function of a single wire harness during later maintenance, which will increase the difficulty of later maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a motor controller wiring harness to solve the above problems. The arc-shaped structure of the clamping plate and the card plate fits the surface of the wiring harness. With the help of the groove limit, multiple wiring harnesses can be clamped independently to avoid tangling and wear. The inclined surface of the insertion block and the fixing block engages and locks the clamping force through the gasket, which not only prevents the wiring harness from loosening, but also avoids the wire body from being damaged by pressure through elastic buffering. It is suitable for fixing the wiring harnesses of different diameters.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a motor controller wiring harness, including a controller, an installation mechanism plugged into the controller, a wiring harness connected to the installation mechanism, a wire clamping mechanism engaging with the wiring harness, the wire clamping mechanism including a clamping plate and a clamping plate, the clamping plate engaging with the wiring harness, a support block fixed to the end of the wiring harness behind the clamping plate, a clamping plate rotatably connected to the support block, a plurality of grooves equally spaced inside the clamping plate, a fixing block fixedly connected to the clamping plate, an insert block engaging with the fixing block, a gasket adhered to the insert block, and the gasket contacting the clamping plate.

[0006] Preferably, the portion of the card plate near the groove is configured with an arc surface structure, and the portion of the clamping plate aligned with the groove is also configured with an arc surface structure.

[0007] Preferably, the wire clamping mechanism further includes a clamping groove, and the clamping plate has a clamping groove at one end away from the support block, with the wire harness located in the clamping groove.

[0008] Preferably, the wire clamping mechanism further includes a slot, and the slot is provided on one side of the fixing block, and the part of the insert block that contacts the fixing block is arranged with an inclined structure.

[0009] Preferably, the insert block and the clamping plate are engaged, and the part of the clamping plate that contacts the gasket has an arc-shaped structure.

[0010] Preferably, a protrusion is fixedly installed at the top of the insert, and the top of the protrusion is spherical.

[0011] Preferably, the mounting mechanism includes a connector and a retaining ring. The connector is inserted into the controller, a wire harness is fixed inside the connector, a retaining ring is fixedly connected to the connector, a collar is threaded onto the retaining ring, and a positioning block is fixedly connected to the collar.

[0012] Preferably, the positioning block is configured in the form of a regular hexagon, and the diameter of the collar is larger than the diameter of the fixing ring.

[0013] Preferably, the mounting mechanism further includes a washer, which is engaged on the positioning block, and the wire harness contacts the inner wall of the washer.

[0014] The beneficial effects of this utility model are as follows: the grooves of the clamping plate and the corresponding parts of the clamping plate are all arc-shaped structures, which have a high degree of fit with the surface of the wire harness. This not only disperses the clamping force through the arc-shaped contact surface, preventing the insulation layer of a single wire harness from being damaged due to excessive local pressure, but also adapts to the shape of wire harnesses of different diameters, ensuring that multiple wire harnesses are stably clamped. The equally spaced grooves can realize the independent separation of a single wire harness, avoiding wire harness entanglement and cross wear, while also facilitating quick identification of the function of a single wire harness during later maintenance, thus improving maintenance efficiency. The contact part between the insert and the fixing block is a beveled structure, which can be quickly positioned by the beveled guide during insertion. After locking, the pads abut against the clamping plate to form a stable mechanical lock, preventing the clamping plate from loosening due to vehicle vibration or wire harness pulling, and ensuring long-term reliable clamping. The pads are made of elastic materials such as rubber, which provide cushioning during clamping, avoiding wear of the clamping plate or inserts due to rigid contact, and extending the service life of the structure.

[0021] 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.

[0022] Please see Figures 1-5 As shown, a motor controller wiring harness includes a controller 1, a mounting mechanism 2 inserted into the controller 1, a wiring harness 3 connected to the mounting mechanism 2, and a wire clamping mechanism 4 engaged with the wiring harness 3. The wire clamping mechanism 4 includes a clamping plate 401 and a clamping plate 402. The clamping plate 402 is engaged with the wiring harness 3. A support block 404 is fixed to the end of the clamping plate 402 facing away from the wiring harness 3. The clamping plate 401 is rotatably connected to the support block 404. A plurality of grooves 403 are equidistantly arranged in the clamping plate 402. A fixing block 406 is fixedly connected to the clamping plate 402, and an insert block 6 is engaged with the fixing block 406. A gasket 7 is adhered to the insert 6, and the gasket 7 contacts the clamping plate 401. The portion of the clamping plate 402 near the groove 403 is arc-shaped, and the portion of the clamping plate 401 aligned with the groove 403 is also arc-shaped. The end of the clamping plate 402 away from the support block 404 has a slot 405, and the wire harness 3 is located in the slot 405. A slot 407 is provided on one side of the fixing block 406. The portion of the insert 6 that contacts the fixing block 406 is inclined, and the insert 6 and the clamping plate 401 are engaged. The portion of the clamping plate 401 that contacts the gasket 7 is arc-shaped.

[0023] As a technical optimization of this utility model, a protrusion 5 is fixedly installed on the top of the insert 6, and the top of the protrusion 5 is set in a spherical structure.

[0024] As a technical optimization of this utility model, the installation mechanism 2 includes a connector 201 and a fixing ring 204. The controller 1 is inserted into the connector 201, and a wire harness 3 is fixed inside the connector 201. The fixing ring 204 is fixedly connected to the connector 201, and a collar 205 is threadedly installed on the fixing ring 204. A positioning block 202 is fixedly connected to the collar 205. The positioning block 202 is arranged in a regular hexagonal structure. The diameter of the collar 205 is larger than the diameter of the fixing ring 204. A washer 203 is engaged on the positioning block 202, and the wire harness 3 is in contact with the inner wall of the washer 203.

[0025] In use, the operator first engages the end of the clamping plate 402 near the slot 405 with the side wall of the wire harness 3. Then, different wire harnesses 3 are categorized by function and sequentially placed into the equally spaced grooves 403 on the clamping plate 402. After embedding the wire harness 3 into the clamping plate 402, each connecting wire is placed independently, which helps prevent cross-entanglement. Next, the clamping plate 401 is rotated around the support block 404 as an axis, so that the arc-shaped part of the clamping plate 401 fits against the surface of the wire harness 3 and covers the top of the groove 403. The groove 403 of the clamping plate 402 and the corresponding part of the clamping plate 401 are both arc-shaped structures, ensuring a high degree of fit with the surface of the wire harness 3. The curved contact surface disperses the clamping force, preventing insulation damage caused by excessive local pressure on a single wire harness 3. It also adapts to the shape of wire harnesses 3 with different diameters, ensuring stable clamping of multiple wire harnesses 3, thus facilitating initial clamping. Next, holding the protrusion 5 fixed at the top of the insert 6, which has a spherical top, insert the insert 6 along the slot 407 of the fixing block 406. Guided by the inclined structure of the insert 6 and the fixing block 406, until the pad 7 on the insert 6 tightly contacts the inner wall of the clamping plate 401, forming a stable mechanical lock. This prevents the clamping plate 401 from loosening due to vehicle vibration or pulling of the wire harness 3. To ensure a long-term reliable clamping state, the wire harness 3 can be securely fixed. When connecting the wire harness 3 to the controller 1, first, the washer 203 is engaged inside the positioning block 202, allowing the wire harness 3 to pass through the inner wall of the washer 203. This ensures that the washer 203 is in close contact with the surface of the wire harness 3, providing initial protection. The washer 203, made of insulating elastic material such as rubber, is placed between the wire harness 3 and the positioning block 202, filling the gap to prevent dust and moisture from entering the connector 201 and buffering the impact of vibration on the terminal contact. Then, the connector 201 is aligned with the interface of the controller 1 and smoothly inserted until it is fully in place, ensuring that the wire harness 3 is properly secured to the controller 1. The circuit is connected; the hexagonal structure of the positioning block 202 is clamped with a tool, and the collar 205 is rotated to tighten it with the threaded fixing ring 204 at the end of the connector 201. The diameter of the collar 205 is larger than the diameter of the fixing ring 204 to ensure connection strength until the positioning block 202 is tightly against the surface of the connector 201. The wiring harness 3 can be protected by the washer 203. When the controller 1 is in use, it receives command signals from the vehicle or equipment control system. These command signals exist in the form of electrical signals and contain information such as speed, torque, and direction required for motor operation. The controller 1 can transmit these signals to the motor through the control signal lines in the wiring harness 3. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
