Description

Technical Field

[0001] This utility model relates to the field of vehicle wiring harness installation technology, and in particular to a wiring harness installation structure and a vehicle. Background Technology

[0002] In vehicle electrical equipment (such as lights), wiring harnesses need to be constrained and fixed to prevent them from swaying between two connection points and causing noise, and to reduce the risk of the harnesses being snagged on surrounding components or structures due to looseness, thereby improving the safety of wiring in the vehicle.

[0003] Currently, wiring harnesses are positioned by setting up locating ribs or other structures on the mounting carrier of electrical equipment. However, the locating ribs constrain and fix the wiring harness in a single direction, such as only constraining the wiring harness along a surface perpendicular to the wiring path. This makes the wiring harness easy to come loose when subjected to forces in other directions. Furthermore, the wiring harness has a certain degree of redundancy after installation, which increases the risk of other factors touching the wiring harness.

[0004] In related technologies, wire harnesses are bonded and fixed to the wiring surface using adhesives such as felt. However, the durability and reliability of this bonding method are low, resulting in a significant risk of the wire harnesses coming loose. Utility Model Content

[0005] In view of this, the present invention aims to provide a wire harness installation structure to effectively constrain the connecting wire harness, prevent the connecting wire harness from coming loose due to redundancy, and improve the installation reliability of the connecting wire harness.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A wire harness mounting structure includes: a wiring assembly comprising a first wiring portion, a second wiring portion, and a connecting wire harness connected between the first wiring portion and the second wiring portion; a first wiring bracket for mounting and fixing the first wiring portion; and a second wiring bracket having a mounting surface for mounting the second wiring portion, wherein the mounting surface has a first wire-clamping portion and two second wire-clamping portions; in a projection along a first direction, the first wiring portion and the second wiring portion are located on the same side of the line containing the two second wire-clamping portions, and the first wire-clamping portion is located on the other side of the line containing the two second wire-clamping portions, wherein the first direction is perpendicular to the mounting surface.

[0007] According to some embodiments of this application, a first opening is defined between the first wire-clamping portion and the mounting surface. The first opening is open to the side opposite to the line connecting the two second wire-clamping portions, and the connecting wire harness can be inserted into the first wire-clamping portion through the first opening. The second wire-clamping portion has a second opening open to the side opposite to the mounting surface, and the connecting wire harness can be inserted into the second wire-clamping portion through the second opening.

[0008] According to some embodiments of this application, the first wire-locking portion includes: a first locking arm, the first locking arm extending in an arc shape, one end of the first locking arm being connected to the mounting surface, and the other end of the first locking arm defining the first opening between the first locking arm and the mounting surface; and a guide arm, the guide arm being connected to the other end of the first locking arm and used for guiding and engaging with the connecting wire harness.

[0009] According to some embodiments of this application, the distance between the guide arm and the mounting surface gradually increases from the first opening toward the side away from the first snap-fit ​​arm, so as to form a guide channel between the guide arm and the mounting surface that is gradually widened toward the side away from the first snap-fit ​​arm.

[0010] According to some embodiments of this application, the first locking part further includes a reinforcing rib, which is disposed on the first locking arm and extends from the end of the first locking arm connected to the mounting surface to the end of the first locking arm connected to the guide arm.

[0011] According to some embodiments of this application, the opening direction of the first opening is perpendicular to the line connecting the two second locking parts.

[0012] According to some embodiments of this application, each of the second wire-clamping portions includes two opposing second clamping arms, the second clamping arms being disposed perpendicular to the mounting surface, and the two second clamping arms defining a second opening and forming a wire-passing channel for the wire harness to pass through.

[0013] According to some embodiments of this application, the through directions of the two second wire-clamping portions intersect, and at least a portion of the first wire-clamping portions are respectively arranged opposite to the through directions of the two second wire-clamping portions.

[0014] According to some embodiments of this application, the first wiring bracket is disposed on one side of the second wiring bracket in a second direction, and the second wiring bracket is provided with a flange near the edge of the first wiring bracket. The flange extends perpendicular to the mounting surface and is provided with a wire-locking groove for the connecting wire harness to pass through and to engage and limit the connecting wire harness; the second direction is intersecting the first direction.

[0015] Compared with the prior art, the wire harness installation structure of this utility model has the following advantages: The first wire clamp and two second wire clamps located at the second connector bracket can constrain the connecting wire harness in multiple directions, improving its ability to withstand tensile forces from multiple directions. This effectively prevents the wire harness from detaching from the second connector bracket, ensuring the constraint effect and avoiding noise and safety hazards caused by wire harness detachment. Simultaneously, the wiring arrangement of the connecting wire harness at the first and second connector brackets is simple, facilitating the arrangement of the connecting wire harness and the assembly and fixation of the first and second connectors at the bracket structure (i.e., the first and second connector brackets).

[0016] Another objective of this utility model is to provide a vehicle.

[0017] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A vehicle comprising the aforementioned wiring harness mounting structure.

[0018] The vehicle described above has the same advantages over the prior art as the wiring harness installation structure described above, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] The wire harness installation structure 100 according to an embodiment of the present utility model includes: a wiring assembly 1, a first wiring bracket 2, and a second wiring bracket 3.

[0024] Combination Figure 1 and Figure 2 As shown, the wiring assembly 1 includes a first wiring portion 11, a second wiring portion 12, and a connecting harness 13. The connecting harness 13 connects the first wiring portion 11 and the second wiring portion 12 to electrically connect the first wiring portion 11 and the second wiring portion 12. Both the first wiring portion 11 and the second wiring portion 12 can be configured as terminals or electrical devices (such as microphones or lamps), and the specific types of the first wiring portion 11 and the second wiring portion 12 are not limited here. In this invention, the first wiring portion 11 is configured as an electrical device (such as a microphone), and the second wiring portion 12 is configured as a terminal. The connecting harness 13 can electrically connect the terminal to the electrical device to supply power to the device.

[0025] Combination Figure 1 and Figure 2 As shown, the first terminal bracket 2 is the mounting carrier for the first terminal part 11, so as to install and fix the first terminal part 11 through the first terminal bracket 2; the second terminal bracket 3 is the mounting carrier for the second terminal part 12, and the second terminal bracket 3 has a mounting surface 301, which is used to install the second terminal part 12. The mounting surface 301 is provided with a first wire clamping part 32 and two second wire clamping parts 33, so as to constrain the connecting wire harness 13 through the first wire clamping part 32 and the second wire clamping part 33, guide the wiring of the connecting wire harness 13 at the first terminal bracket 2 and the second terminal bracket 3, and improve the wiring reliability of the connecting wire harness 13.

[0026] Further integration Figure 4As shown, in the projection of the first direction, the first wiring portion 11 and the second wiring portion 12 are located on the same side of the straight line where the two second wire-clamping portions 33 are located, and the first wire-clamping portion 32 is located on the other side of the straight line where the two second wire-clamping portions 33 are located. This allows the first wire-clamping portion 32 to guide and constrain the wire harness portion (i.e., a part of the connecting wire harness 13) between the two second wire-clamping portions 33, thus preventing redundancy in the connecting wire harness 13. The first direction is perpendicular to the mounting surface 301.

[0027] Combination Figure 1 , Figure 3 and Figure 4 As shown, the connecting wire harness 13 needs to be engaged with a second wire clamping part 33, a first wire clamping part 32 and another second wire clamping part 33 in sequence. That is, the part of the connecting wire harness 13 located between the two second wire clamping parts 33 is engaged with the first wire clamping part 32 so as to constrain the part of the connecting wire harness 13 between the two second wire clamping parts 33 through the first wire clamping part 32.

[0028] It is understandable that if the first wire clamping part 32 is not provided, the connecting wire harness 13 located between the two second wire clamping parts 33 cannot be effectively constrained, which will lead to redundancy of the connecting wire harness 13 in this area. Consequently, the connecting wire harness 13 may come into contact with its surrounding components and there is a risk of it coming off from the second wire clamping part 33.

[0029] In this utility model, by setting the first wire-clamping part 32 on the side of the two second wire-clamping parts 33 away from the first wiring part 11 and the second wiring part 12, that is, the first wire-clamping part 32 is not collinear with the two second wire-clamping parts 33, thereby constraining the connecting wire harness 13 in a three-point manner through one first wire-clamping part 32 and two second wire-clamping parts 33, the constraint effect of the second wiring bracket 3 on the connecting wire harness 13 is improved.

[0030] It should be noted that in the vehicle's electrical equipment (such as lights), the wiring harness needs to be constrained and fixed to prevent the wiring harness from shaking between two connection points and causing noise, and to reduce the risk of the wiring harness being snagged by its surrounding parts or structures due to looseness, thereby improving the wiring safety in the vehicle.

[0031] Currently, wiring harnesses are positioned using structures such as positioning ribs on the mounting carrier of electrical equipment. However, the positioning ribs only constrain the wiring harness in a single direction, such as perpendicular to the wiring surface. This makes the wiring harness prone to detachment under forces from other directions, and the wiring harness has a certain degree of redundancy after installation, increasing the risk of other factors contacting it. Related technologies use adhesives such as felt to bond the wiring harness to the wiring surface; however, adhesive fixation methods have low durability and reliability, resulting in a significant risk of the wiring harness detaching.

[0032] According to the wire harness installation structure 100 of this utility model embodiment, the second wiring bracket 3 is provided with multiple wire clamping structures (i.e., a first wire clamping part 32 and two second wire clamping parts 33) to constrain the connecting wire harness 13 at multiple points, so as to improve the constraint effect of the second wiring bracket 3 on the connecting wire harness 13 and ensure the fixing effect of the connecting wire harness 13 in the wire harness installation structure 100.

[0033] Combination Figure 1 , Figure 2 as well as Figure 4 As shown, in some embodiments of this utility model, a first opening 3201 is defined between the first wire-clamping portion 32 and the mounting surface 301, and the first opening 3201 is open toward the side opposite to the line connecting the two second wire-clamping portions 33. The connecting wire harness 13 can be inserted into the first wire-clamping portion 32 through the first opening 3201, so that the connecting wire harness 13 is constrained and fixed by the cooperation between the first wire-clamping portion 32 and the mounting surface 301. The second wire-clamping portion 33 is formed with a second opening 3301 that is open toward the side opposite to the mounting surface 301, and the connecting wire harness 13 can be inserted into the second wire-clamping portion 33 through the second opening 3301, so that the connecting wire harness 13 is constrained by the second wire-clamping portion 33.

[0034] Combination Figure 1 , Figure 3 and Figure 4 As shown, the first opening 3201 faces away from the side connecting the two second wire clamping portions 33, so that the first wire clamping portion 32 can constrain and limit the part of the connecting wire harness 13 located between the two second wire clamping portions 33 to the side away from the two second wire clamping portions 33, so as to prevent the part of the connecting wire harness 13 between the two second wire clamping portions 33 from becoming redundant.

[0035] It is understandable that, since the opening directions of the first wire-locking part 32 and the second wire-locking part 33 are different, the first wire-locking part 32 and the second wire-locking part 33 can connect the wire harness 13 from multiple directions for constraint, thereby improving the constraint effect of the first wire-locking part 32 and the second wire-locking part 33 on the connected wire harness 13 and reducing the risk of the connected wire harness 13 coming off.

[0036] It should be noted that if the wiring harness installation structure 100 only constrains the connecting wiring harness 13 using the same snap-fit ​​structure, the connecting wiring harness 13 may easily come out of the mounting port of the snap-fit ​​structure when subjected to a force in a certain direction, affecting the constraint and fixation effect on the connecting wiring harness 13.

[0037] In this utility model, the second wiring bracket 3 is provided with a first wire-clamping part 32 and a second wire-clamping part 33. The first wire-clamping part 32 and the second wire-clamping part 33 are installed in different directions for the connecting wire harness 13 to be clamped in, thereby increasing the difficulty for the connecting wire harness 13 to come out from the first wire-clamping part 32 and the second wire-clamping part 33, and improving the constraint and fixation effect on the connecting wire harness 13.

[0038] Combination Figure 1 and Figure 2 As shown, in a further embodiment of the present invention, the first wire-locking portion 32 includes a first locking arm 321 and a guide arm 322. The first locking arm 321 extends in an arc shape, and one end of the first locking arm 321 is connected to the mounting surface 301. The other end of the first locking arm 321 defines a first opening 3201 between itself and the mounting surface 301. That is, the end of the first locking arm 321 is spaced apart from the mounting surface 301 in a first direction so that the connecting wire harness 13 can be inserted into the first wire-locking portion 32.

[0039] Furthermore, the guide arm 322 is connected to the other end of the first snap-fit ​​arm 321 (i.e., the end of the first snap-fit ​​arm 321 that cooperates with the mounting surface 301 to form the first opening 3201), and the guide arm 322 is used to guide and cooperate with the connecting wire harness 13 so as to assist the connecting wire harness 13 in snapping into a position suitable for snapping and cooperating with the first snap-fit ​​arm 321.

[0040] Reference Figure 2 As shown, since the first snap-fit ​​arm 321 is arc-shaped, a tapered structure is formed at the free end of the first snap-fit ​​arm 321 (i.e. the end of the first snap-fit ​​arm 321 that is suspended relative to the mounting surface 301), making it difficult for the connecting wire harness 13 to come out after it is snapped into the area enclosed between the first snap-fit ​​arm 321 and the mounting surface 301, thus ensuring the constraint effect of the first snap-fit ​​arm 321 on the connecting wire harness 13.

[0041] Reference Figure 2 As shown, in a further embodiment of the present invention, the distance between the guide arm 322 and the mounting surface 301 gradually increases from the first opening 3201 toward the side away from the first snap-fit ​​arm 321, so as to form a guide channel between the guide arm 322 and the mounting surface 301 that is gradually widened toward the side away from the first snap-fit ​​arm 321, so that the guide arm 322 can play a good guiding role for the connecting wire harness 13, thereby facilitating the insertion of the connecting wire harness 13 into the first snap-fit ​​arm 321.

[0042] Understandably, during the engagement of the first wire-clamping part 32 of the connecting wire harness 13, the connecting wire harness 13 can be placed between the guide arm 322 and the mounting surface 301 (that is, part of the connecting wire harness 13 is placed in the guide channel). By pulling the connecting wire harness 13, the connecting wire harness 13 can be deformed by squeezing the free end of the first clamping arm 321, so as to clamp the connecting wire harness 13 into the first clamping arm 321, thereby realizing the clamping constraint of the first wire-clamping part 32 on the connecting wire harness 13.

[0043] In this embodiment of the invention, the snap-fit ​​mechanism between the first wire-clamping part 32 and the connecting wire harness 13 is simple and provides good constraint, effectively preventing the wire harness from coming out of the first wire-clamping part 32. Simultaneously, the guide arm 322 assists in the snap-fit ​​mechanism between the connecting wire harness 13 and the first snap-fit ​​arm 321, facilitating the insertion of the connecting wire harness 13 into the first snap-fit ​​arm 321.

[0044] like Figure 2 As shown, in some embodiments of this utility model, the first snap-fit ​​part 32 further includes a reinforcing rib 323. The reinforcing rib 323 is disposed at the first snap-fit ​​arm 321 and extends from the end of the first snap-fit ​​arm 321 connected to the mounting surface 301 to the end of the first snap-fit ​​arm 321 connected to the guide arm 322, so as to improve the structural strength of the first snap-fit ​​arm 321 through the reinforcing rib 323.

[0045] Reference Figure 2 As shown, the reinforcing rib 323 is provided on the side surface of the snap-fit ​​arm away from the connecting wire harness 13 to prevent interference between the reinforcing rib 323 and the connecting wire harness 13. Furthermore, the extension direction of the reinforcing rib 323 is the same as that of the first snap-fit ​​arm 321, so that the reinforcing rib 323 extends in an arc shape. In this way, the structural strength of the first snap-fit ​​arm 321 can be fully improved by the reinforcing rib 323, reducing the risk of cracking and other problems caused by insufficient strength at the first snap-fit ​​arm 321.

[0046] Reference Figure 2 The reinforcing rib 323 is connected to the mounting surface 301 to increase the mating area between the first wire-clamping portion 32 and the mounting surface 301, thereby improving the connection reliability between the first wire-clamping portion 32 and the mounting surface 301. Simultaneously, the reinforcing rib 323 is positioned away from the arc-shaped opening of the first clamping arm 321 to avoid occupying the space between the first clamping arm 321 and the mounting surface 301 used for arranging the connecting wire harness 13.

[0047] In some embodiments of this application, the opening direction of the first opening 3201 is perpendicular to the line connecting the two second wire-clamping portions 33, so that the first clamping arm 321 can apply a constraint force perpendicular to the line connecting the two second wire-clamping portions 33 to the connecting wire harness 13, thereby improving the clamping constraint effect of the first wire-clamping portion 32 on the connecting wire harness 13.

[0048] In a further embodiment of this application, the first wire clamping part 32 is disposed on the normal line at the midpoint of the line connecting the two second wire clamping parts 33, so that the first wire clamping part 32 is located at the middle position of the two wire clamping parts, so that the connecting wire bundle 13 is subjected to uniform force at the first wire clamping part 32, thereby improving the constraint effect of the first wire clamping part 32 on the connecting wire bundle 13 located between the two wire clamping parts.

[0049] It is understandable that the greater the distance between the first wire clamping part 32 and the connection between the two second wire clamping parts 33, the longer the connecting wire bundle 13 between the two second wire clamping parts 33, and the first wire clamping part 32 can play a good constraining effect on the connecting wire bundle 13 in this part.

[0050] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, each second wire-clamping portion 33 includes two opposing second clamping arms 331. The second clamping arms 331 are arranged perpendicular to the mounting surface 301, and a second opening 3301 is defined between the two second clamping arms 331. A wire-passing channel for the wire harness to pass through is formed between the two second clamping arms 331. The connecting wire harness 13 can pass through the second wire-clamping portion 33 from the wire-passing channel so as to constrain the connecting wire harness 13 by the two second clamping arms 331 located on both sides.

[0051] Reference Figure 3 and Figure 4 As shown, when the connecting wire harness 13 is engaged with the second wire clamping part 33, the connecting wire harness 13 can be arranged between the two second clamping arms 331 from the second opening 3301, so that the two second clamping arms 331 can constrain the two sides of the wire harness, and the two second clamping arms 331 can guide the wiring of the wire harness, making it easier for the connecting wire harness 13 to be arranged at the second wiring bracket 3.

[0052] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the through directions of the wire passages of the two second wire-clamping portions 33 intersect, and at least a portion of the first wire-clamping portions 32 are respectively arranged opposite to the wire passages of the two second wire-clamping portions 33, thereby facilitating the optimization of the wiring path of the connecting wire harness 13.

[0053] It is understandable that the first wire clamping part 32 is used to engage with the connecting wire harness 13 at a position close to the intersection of the two wire passages in the two second wire clamping parts 33. This facilitates the optimization of the wiring path of the connecting wire harness 13, avoids excessive bending of the connecting wire harness 13 due to excessively large wiring angle in the part of the connecting wire harness 13 located between the first wire clamping part 32 and the second wire clamping part 33, and improves the constraint effect of the second wiring bracket 3 on the connecting wire harness 13.

[0054] In a further embodiment of the present invention, a limiting rib 332 is provided on the second snap-fit ​​arm 331. The limiting rib 332 is provided on the side surface of the second snap-fit ​​arm 331 facing the connecting wire harness 13 and is raised towards the inside of the wire passage so that the limiting rib 332 abuts against the connecting wire harness 13 to position the connecting wire harness 13 and further improve the constraint effect of the second wire clamping part 33 on the wire harness.

[0055] Furthermore, the limiting rib 332 extends along the first direction on the second snap-fit ​​arm 331 to further improve the structural strength of the second snap-fit ​​arm 331 and enhance its anti-deformation performance, so as to ensure the reliability of the second snap-fit ​​arm 331 in constraining the connecting wire harness 13.

[0056] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the first terminal bracket 2 is disposed on one side of the second terminal bracket 3 in the second direction, and the second terminal bracket 3 is provided with a flange 31 near the edge of the first terminal bracket 2. The flange 31 extends perpendicularly to the mounting surface 301, and a wire-holding groove 311 is provided at the flange 31. The wire-holding groove 311 is used for the connecting wire harness 13 to pass through and engage with the connecting wire harness 13 for limiting and constraining, so as to improve the constraint effect of the second terminal bracket 3 on the connecting wire harness 13. The second direction intersects with the first direction.

[0057] It is understandable that the first direction can be set perpendicular to the second direction. Thus, the flange 31 is set perpendicular to the mounting surface 301, and the wire-holding groove 311 formed on the flange 31 is used for the connecting wire harness 13 to pass through, and can keep the connecting wire harness 13 in a position that fits against the mounting surface 301, which facilitates the routing of the connecting wire harness 13 and ensures the constraint effect of the connecting wire harness 13 at the second terminal bracket 3.

[0058] Combination Figure 1 and Figure 4As shown, it should be noted that the setting position and extension direction of the wire clamping groove 311 on the flange 31 can be designed according to the arrangement position of the first wiring part 11 relative to the second wiring bracket 3, so that the connecting wire harness 13 can smoothly transition the wiring, reduce the wiring difficulty of the connecting wire harness 13, and the wire clamping groove 311 can play a good constraining effect on the wiring arrangement of the connecting wire harness 13.

[0059] According to the wire harness installation structure 100 of this utility model embodiment, the redundancy of the connecting wire harness 13 is controlled by the first wire clamping part 32 on the mounting surface 301, so that the connecting wire harness 13 is kept within the tolerance range, that is, the connecting wire harness 13 can be installed normally and is not easy to come out, and the multi-segment wire harness structure constrained and fixed by multiple wire clamping parts (i.e., the first wire clamping part 32 and the second wire clamping part 33) will not have too much redundancy.

[0060] It should be noted that the actual length of the connecting wire harness 13 is preferably between the minimum fixed wire harness length and the minimum detachable wire harness length that passes through one first wire clamping part 32 and two second wire clamping parts 33 between the first wiring part 11 and the second wiring part 12, so as to tighten the connecting wire harness 13 while preventing the connecting wire harness 13 from coming out.

[0061] It is understandable that the "minimum fixed wire harness length" is the sum of the straight-line distance between the first connector 11 and the wire clamping groove 311, the straight-line distance between the wire clamping groove 311 and a second wire clamping part 33 (the second wire clamping part 33 near the flange 31), the straight-line distance between the two wire clamping parts and the first wire clamping part 32, and the straight-line distance between the other second wire clamping part 33 and the second connector 12. If the length of the connecting wire harness 13 is less than the minimum fixed wire harness length, the connecting wire harness 13 cannot be constrained and fixed through the above-mentioned multiple wire clamping parts. The "minimum detachable length" refers to the total length of the connecting wire harness 13 that is detached from the first wire clamping part 32 due to excessive redundancy.

[0062] In some embodiments of the utility model, the first wiring bracket 2 is provided with a mounting groove 201, which is open to one side in the first direction (which is also the side where the mounting surface 301 is located), and a hook 21 is provided in the mounting groove 201. The hook 21 is used to engage with the first wiring part 11 to fix the first wiring part 11 at the first wiring bracket 2. The assembly method is simple and highly reliable.

[0063] Combination Figures 1-4 The assembly process of the wire harness mounting structure 100 according to an embodiment of this application is described as follows: First, the second wiring part 12 is assembled and fixed on the second wiring bracket 3, and the connecting wire harness 13 led out from the second wiring bracket 3 passes through a second wire clamping part 33, a first wire clamping part 32 and another second wire clamping part 33 in sequence and then passes through the wire clamping groove 311. Then, the first wiring part 11 is clamped and fixed at the first wiring bracket 2 to complete the assembly of the wire harness installation structure 100.

[0064] The wire harness mounting structure 100 according to the present invention has at least the following advantages compared with the prior art: The first wire clamping part 32 and two second wire clamping parts 33 provided at the second terminal bracket 3 can constrain the connecting wire harness 13 in multiple directions, improving the ability of the connecting wire harness 13 to withstand tensile forces in multiple directions. This effectively prevents the wire harness from coming off the second terminal bracket 3, ensuring the constraint effect of the connecting wire harness 13 at the second terminal bracket 3 and avoiding noise and safety hazards caused by wire harness detachment. At the same time, the wiring arrangement of the connecting wire harness 13 at the first terminal bracket 2 and the second terminal bracket 3 is simple, facilitating the arrangement of the connecting wire harness 13 and the assembly and fixation of the first terminal part 11 and the second terminal part 12 at the bracket structure (i.e., the first terminal bracket 2 and the second terminal bracket 3).
