Abstract
Description
Technical Field
[0001] The present application relates to the technical field of wiring harness installation, and in particular to a low-voltage wiring harness integrated installation structure. Background Art
[0002] The low-voltage wiring harness of a motor typically includes a temperature sensor harness and a resolver harness, which are used to obtain the temperature of the motor's stator windings, as well as the motor's speed and rotor position, respectively. The resolver harness typically includes six signal wires, or 6-pin wires, while the temperature sensor harness typically includes two signal wires, or 2-pin wires. When the low-voltage wiring harness is electrically connected to the motor controller, it is typically integrated. For example, the temperature sensor harness and the resolver harness, totaling eight signal wires, are integrated onto the female end of an 8-pin connector. The female end of the connector mates with the corresponding male end of the connector to achieve electrical connection to the motor controller. During assembly, to prevent the low-voltage wiring harness from shaking or even becoming entangled with other components during motor operation, cable ties are often used to secure the temperature sensor harness and resolver harness together. These cables are then tied to buckles or other structures inside the motor housing to control their routing. However, in actual operation, it is difficult to tie the rotating transformer wiring harness, and it is easy to be damaged by the tension of the tie; at the same time, the tie is easy to loosen due to vibration after being tied.

[0026] The embodiment of the present application provides a low-voltage wiring harness integrated installation structure, such as Figure 1 and Figure 2 As shown, the low-voltage wiring harness integrated installation structure includes:
[0027] The resolver wiring harness 100 includes a resolver stator 110 and a first wiring harness 120 , one end of the first wiring harness 120 being connected to the resolver stator 110 ;
[0028] The temperature sensor harness 200 includes a temperature sensor 210, a second harness 220, a temperature connector 230, and a third harness 240. The temperature connector 230 includes a first plug terminal 231 and a second plug terminal 232. The first plug terminal 231 and the second plug terminal 232 are pluggable. The first plug terminal 231 is connected to one end of the second harness 220, the second plug terminal 232 is connected to one end of the third harness 240, and the temperature sensor 210 is connected to the other end of the second harness 220.
[0029] an integrated connector terminal 300 connected to the other end of the first wiring harness 120 and the other end of the third wiring harness 240;
[0030] The second connector terminal 232 is further provided with a harness buckle 400 and a fixing structure. The first harness 120 is arranged in the harness buckle 400. The fixing structure is used to connect the second connector terminal 232 to the motor housing.
[0031] like Figure 1 As shown, in this embodiment, the resolver stator 110 is annular and serves as a functional component of the resolver wiring harness 100. The resolver stator 110 can be fixed in the motor housing and sleeved outside the rotor to obtain the motor speed and rotor position. The first wiring harness 120 is used to connect the resolver stator 110 to the integrated plug-in terminal 300 so that the resolver wiring harness 100 can transmit the obtained motor speed and rotor position to the motor sensor. The first wiring harness 120 can include 6 signal wiring harnesses, that is, the first wiring harness 120 can be set as a 6-pin line.
[0032] like Figure 1 As shown, temperature sensor 210 serves as a functional component of temperature sensor harness 200. It can preferably be a thermocouple temperature sensor 210. When thermocouple temperature sensor 210 is in direct contact with the motor's stator winding, it can acquire the temperature of the motor's stator winding. Second harness 220 and third harness 240 connect temperature sensor 210 to integrated plug-in terminals 300 via temperature connector 230, allowing the temperature harness to transmit the acquired stator winding temperature to the motor sensor. Temperature connector 230 can include a first plug-in terminal connected to second harness 220 and a second plug-in terminal connected to third harness 240. It will be appreciated that the first and second plug-in terminals form a pair of mating male and female connector terminals. Second harness 220 and third harness 240 can each include two signal wires, i.e., two-pin wires. Accordingly, temperature connector 230 is a two-pin connector.
[0033] In this embodiment, the integrated connector terminal 300 can be configured as a male connector terminal. Because it integrates the 6-pin first wiring harness 120 and the 2-pin third wiring harness 240, it is an 8-pin connector. The integrated connector terminal 300 can be used with the 8-pin female connector terminal to enable signal transmission between the resolver wiring harness 100 and the temperature sensor wiring harness 200.
[0034] like Figure 1 and Figure 2 As shown, in this embodiment, a harness clip 400 is provided on the second connector terminal 232. This allows the third wiring harness 240 (2-pin cable) to be secured to the first wiring harness 120 (6-pin cable) via the harness clip 400. In this case, the first wiring harness 120 is disposed within the harness clip 400. When the second wiring harness 220 and the third wiring harness 240 are connected via the temperature connector 230, the second wiring harness 220 is indirectly connected to the first wiring harness 120. Furthermore, a fixing structure is provided on the second connector terminal 232 to secure the second connector terminal 232 within the motor housing. After assembly, the first wiring harness 120 of the resolver wiring harness 100, which has relatively high structural strength, serves as the primary support component of the integrated structure formed by the resolver wiring harness 100 and the temperature sensor wiring harness 200. Furthermore, when this integrated structure is secured to the motor housing, neither wiring harness is susceptible to shaking or becoming entangled with other components.
[0035] It is understood that the present application can fix the second and third wiring harnesses 220 and 240 of the temperature sensor wiring harness 200 to the first wiring harness 120 of the rotary transformer wiring harness 100 by configuring the temperature sensor wiring harness 200 as a second wiring harness 220 and a third wiring harness 240 connected via a temperature connector 230, and providing a wiring harness buckle 400 on the second plug-in terminal 232 of the temperature connector 230. At the same time, a fixing structure is also provided on the second plug-in terminal 232 to fix the second plug-in terminal to the motor housing. Based on this, during the assembly process of the present application, it is only necessary to clip the first wiring harness 120 into the wiring harness buckle 400 and connect the fixing structure to the motor housing without the need for binding. Therefore, the low-voltage wiring harness integrated installation structure provided by the present application is simple to operate, convenient and fast, and the first wiring harness 120 of the rotary transformer wiring harness 100 is not easily damaged.
[0036] Specifically, the fixing structure is a fixing leg 500, and the fixing leg 500 is used to be plugged into the motor housing.
[0037] like Figure 1 and Figure 2As shown, in this embodiment, for example, the motor housing can be provided with a rib at the mounting location of the second plug-in terminal 232. The rib is used to support the second plug-in terminal 232 so that the first wiring harness 120 of the rotary transformer wiring harness 100 is not easily subjected to tension when the second plug-in terminal 232 is connected to the motor housing. The rib can be hollow to form a mounting hole; in this case, the fixing structure can be provided as a fixed leg 500, which is a columnar plug-in structure that is compatible with the mounting hole, such as a cylindrical structure. During assembly, the second plug-in terminal 232 can be connected to the motor housing by inserting the fixed leg 500 into the mounting hole.
[0038] Of course, in some embodiments, the fixing structure may be a separately provided fastener, such as a screw, which may pass through the second connector 232 and be screwed onto the motor housing to lock and fix the second connector 232 .
[0039] It can be understood that, by providing the fixing structure on the fixing legs 500 plugged into the motor housing, this embodiment further improves the convenience of the low-voltage wiring harness integrated installation structure during installation, thus saving time and effort.
[0040] Specifically, an anti-slip structure 510 is provided on the fixed leg 500 .
[0041] like Figure 1 and Figure 2 As shown, in this embodiment, for example, when the fixed leg 500 is inserted into the mounting hole, its anti-dropout function relies primarily on the frictional resistance between the fixed leg 500 and the inner wall of the mounting hole. In this embodiment, the fixed leg 500 is also provided with an anti-slip structure 510. This anti-slip structure 510 increases the frictional resistance between the fixed leg 500 and the inner wall of the mounting hole, thereby preventing the fixed leg 500 from dropping out when inserted into the motor housing. This allows the second connector 232 to stably and effectively integrate the wiring harness and control its routing.
[0042] More specifically, the anti-slip structure 510 is a thread provided on the outside of the fixed leg 500 .
[0043] like Figure 1 and Figure 2 As shown, in this embodiment, for example, the portion of the fixing leg 500 that directly contacts the inner wall of the mounting hole can be the outer side of the fixing leg 500, and the anti-slip structure 510 can be provided as a thread on the outer side. The form of the thread is not limited and can be appropriately configured according to actual needs. When the fixing leg 500 is inserted into the mounting hole, the anti-slip structure 510 has an interference fit with the mounting hole, preventing the fixing leg 500 from falling off.
[0044] More specifically, the fixing legs 500 are at least partially hollow, so that the fixing legs 500 are contractible in the radial direction.
[0045] like Figure 1 and Figure 2 As shown, in this embodiment, for example, the fixing leg 500 can also be configured as a hollow structure that is radially retractable. Specifically, the hollow portion can be coaxial with the mounting hole. Furthermore, the fixing leg 500 can be provided with a notch 520 that extends through the hollow portion. The fixing leg 500 can also be preferably made of a material with a certain degree of elasticity. When the fixing leg 500 is inserted into the mounting hole, the fixing leg 500 can be compressed radially by the inner wall of the mounting hole to reduce its inner diameter. The elastic force of the fixing leg 500 allows it to tightly abut the inner wall of the mounting hole, ensuring its stability during insertion.
[0046] It can be understood that, in this embodiment, by configuring the fixing leg 500 as a hollow structure that is retractable along its radial direction, it is possible to ensure that the fixing leg 500 is convenient to install while further improving its stability during installation.
[0047] Specifically, an elastic structure is provided at one end of the fixing leg 500 close to the second plug-in terminal 232 , and the elastic structure is used to abut against the motor housing when the fixing leg 500 is plugged into the motor housing.
[0048] like Figure 1 and Figure 2 As shown, in this embodiment, the end of the fixing leg 500 closest to the second connector 232 is the top of its thread, where the elastic structure is located. When the fixing leg 500 is inserted into the mounting hole, the top of the fixing leg 500 moves closer to the motor housing as the insertion depth increases. When the fixing leg 500 is properly installed, the elastic structure abuts against the motor housing. At this point, the elastic structure deforms under the action of the driving force and provides elastic support for the second connector 232.
[0049] It can be understood that, in this embodiment, an elastic structure for abutting against the motor housing is provided on the fixed leg 500, so that elastic contact is formed between the second plug terminal 232 and the motor housing, thereby reducing the vibration of the second plug terminal 232, so that the second plug terminal 232 is not easily worn and is not easy to fall off.
[0050] More specifically, the elastic structure is a pair of elastic-plastic bodies 600 disposed opposite to each other, and the pair of elastic-plastic bodies 600 are spread out in a direction close to the bottom of the fixed leg 500 .
[0051] like Figure 1 and Figure 2As shown, in this embodiment, for example, the elastic-plastic body 600 can be provided as a pair and arranged on both sides of the fixed leg 500. The elastic-plastic body 600 can also be made of a material with a certain elasticity to enable it to have a certain elastic deformation ability. The pair of elastic-plastic bodies 600 can be provided in a shape similar to a "V", and the opening of the "V" shape can be oriented toward the bottom of the fixed leg 500, that is, the pair of elastic-plastic bodies 600 can be opened in a direction close to the bottom of the fixed leg 500. When the fixed leg 500 is inserted into the mounting hole and the pair of elastic-plastic bodies 600 abut against the motor housing, the pair of elastic bodies can be further opened under the action of the driving force, and the two ends of the elastic bodies abutting against the motor housing can move away from each other.
[0052] Of course, in some embodiments, the elastic structure may also be configured as a spring member sleeved on the fixed leg 500 .
[0053] It can be understood that, in this embodiment, by configuring the elastic structure as a pair of oppositely disposed elastic-plastic bodies 600 , relatively stable contact can be formed between the elastic structure and the motor housing, thereby enabling the elastic structure to function stably and effectively.
[0054] Specifically, the length of the third wire harness 240 is shorter than the length of the second wire harness 220 .
[0055] like Figure 1 As shown, in this embodiment, for example, in the temperature sensor wiring harness 200, the second wiring harness 220 can be arranged relatively long, while the third wiring harness 240 can be arranged relatively short. This arrangement allows the temperature connector 230 to be positioned relatively close to the integrated plug-in terminal 300. This proximity to the integrated plug-in terminal 300 facilitates integration of the third wiring harness 240 with the first wiring harness 120 via the wiring harness clip 400 without affecting the routing of the first and second wiring harnesses 120 and 220.
[0056] Specifically, the first connector terminal 231 is a female connector terminal, and the second connector terminal 232 is a male connector terminal.
[0057] like Figure 1 and Figure 2 As shown, in this embodiment, for example, in the temperature connector 230, the first connector terminal 231 can be configured as a female connector terminal, and the second connector terminal 232 can be configured as a male connector terminal. It is easy to understand that during the insertion process of the temperature connector 230, the first connector terminal 231, which serves as the female connector terminal and is relatively movable, is more easily inserted into the second connector terminal 232, which serves as the male connector terminal and is relatively fixed, which is more convenient.
[0058] Specifically, the harness buckle 400 and the fixing structure are integrally formed with the second connector terminal 232 .
[0059] like Figure 1 and Figure 2 As shown, in this embodiment, the second connector 232 includes an outer molded part, and the harness clip 400 and the fixing structure can be integrally molded with the outer molded part. Similarly, the threads on the fixing legs 500 and the pair of elastic plastic bodies 600 are also integrally molded with the outer molded part of the second connector 232.
[0060] It can be understood that, in this embodiment, by integrating the second connector terminal 232 with the harness buckle 400 and the fixing structure, the preparation process can be made convenient and quick while ensuring the structural stability.
[0061] The implementation principle of the low-voltage wiring harness integrated installation structure provided in the embodiment of the present application is as follows:
[0062] During assembly, the second connector 232 is positioned on the first wiring harness 120 using the harness clip 400, connecting the third wiring harness 240 to the first wiring harness 120. The first connector 231 is then plugged into the second connector 232, connecting the second wiring harness 220 to the third wiring harness 240. The resolver stator 110 and temperature sensor 210 are then positioned in their designated locations. The fixed legs 500 are then inserted into the mounting holes, and the pair of elastomeric bodies 600 are brought into contact with the motor housing.
[0063] The present application sets the temperature sensor harness 200 as a second harness 220 and a third harness 240 connected via a temperature connector 230, and sets a harness clip 400 on the second plug-in terminal 232 of the temperature connector 230, so that the second harness 220 and the third harness 240 of the temperature sensor harness 200 can be fixed to the first harness 120 of the rotary transformer harness 100; at the same time, a fixing structure is also set on the second plug-in terminal 232 to fix the second plug-in terminal to the motor housing. Based on this, during the assembly process of the present application, it is only necessary to clip the first harness 120 into the harness clip 400 and connect the fixing structure to the motor housing without the need for binding. Therefore, the low-voltage harness integrated installation structure provided by the present application is simple to operate, convenient and fast, and the first harness 120 of the rotary transformer harness 100 is not easily damaged.
[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0065] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
