Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to junction boxes, vehicle body structures, and vehicles. Background Technology

[0002] With the increasing popularity of new energy vehicles, the application of high-voltage wiring harnesses in vehicle systems continues to increase. High-voltage systems have complex structures, requiring centralized management and distribution of high-voltage wiring harnesses from different sources and destinations. This facilitates the monitoring, maintenance, and fault location of high-voltage wiring harnesses. Junction boxes can centrally integrate high-voltage wiring harnesses from multiple detection points or branch lines, thereby fixing the high-voltage wiring harnesses and ensuring the normal operation of vehicle functions.

[0003] In the prior art, a connection device for high-voltage wiring harnesses in new energy vehicles is provided, including a junction box and a junction head. The junction head is located at the front end of the junction box, and multiple junction cores are provided inside the junction head. The junction box has a rear cover, a sliding switch at the top, a sliding block at the bottom, and an iron piece with a copper contact on the sliding block. A flexible wire is connected to the end of each junction core, and the flexible wire is connected to the copper contact. The junction box has an opening at the rear, through which the high-voltage wiring harness is connected to the junction box. The junction box also contains a conductive plate and a junction plate. The conductive plate connects the outer core of the high-voltage wiring harness to the junction head, and the junction plate is connected to the inner core of the high-voltage wiring harness through multiple wires.

[0004] However, in the existing technology, it is difficult to repair and replace the components in the junction box when they malfunction, which makes the repair and replacement of parts inconvenient and affects the efficiency of repair and replacement. Utility Model Content

[0005] One objective of this application is to provide a junction box to address the problem of improving the efficiency of junction box maintenance and replacement. A second objective of this application is to provide a vehicle body structure. A third objective of this application is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, embodiments of this application provide a junction box, including a housing and a fixing member. The housing includes an installation channel; the fixing member includes a first fixing structure and a second fixing structure, which are detachably connected and define a wire passage. The wire passage is used to pass wire harnesses through the wire passage, and the fixing member is disposed within the installation channel and engaged with the housing.

[0008] According to the aforementioned technical means, by using a fastener located in the installation channel and engaging with the housing, it is easy to install the fastener into the installation channel of the housing and to easily remove the fastener from the installation channel. Furthermore, by setting up a first fixing structure and a second fixing structure, which are detachably connected and form a wiring channel, the wire harness can be threaded through the wiring channel. This effectively prevents the wire harness from shifting or loosening during use. Simultaneously, the detachable connection of the first and second fixing structures allows for quick assembly and disassembly, facilitating both the removal and placement of the wire harness within the wiring channel. In this way, when it is necessary to repair or replace components inside the junction box, such as wire harnesses and fasteners, it is convenient to disassemble the components, thereby facilitating maintenance and component replacement, improving the efficiency of junction box maintenance and component replacement. Moreover, the engagement of the fastener with the housing also enhances the overall structural strength of the junction box.

[0009] In some embodiments, one of the first fixing structure and the second fixing structure is provided with a first snap-fit ​​hole, and the other of the first fixing structure and the second fixing structure is provided with a first snap-fit ​​protrusion, the first snap-fit ​​protrusion being snapped into the first snap-fit ​​hole.

[0010] Based on the above technical means, by setting the first snap-fit ​​protrusion and the first snap-fit ​​hole, the first snap-fit ​​protrusion and the first snap-fit ​​hole can be quickly positioned and locked, and can be assembled and disassembled without tools, further improving the portability of the hub box.

[0011] In some embodiments, one of the first fixing structure and the second fixing structure is provided with a protrusion protruding toward the other, a first snap-fit ​​hole is provided on the protrusion and extends along a first direction, the first direction being perpendicular to the arrangement direction of the first fixing structure and the second fixing structure; the other of the first fixing structure and the second fixing structure is provided with a first snap-fit ​​protrusion protruding along the first direction.

[0012] According to the above technical means, the protrusion extends along the direction perpendicular to the arrangement of the fixing parts. After the first snap-fit ​​protrusion extends into the first snap-fit ​​hole, the locking direction of the snap-fit ​​mechanism is perpendicular to the arrangement direction of the first fixing structure and the second fixing structure, which improves the stability of the connection between the first fixing structure and the second fixing structure. During assembly, it is only necessary to align the first fixing structure and the second fixing structure and insert the first snap-fit ​​protrusion into the first snap-fit ​​hole to complete the fixing. The assembly is simple and quick.

[0013] In some embodiments, the device further includes a first end cap and a second end cap. The first end cap covers one end of the mounting channel and is detachably connected to the housing. The second end cap covers the other end of the mounting channel and is detachably connected to the housing. The first end cap has a first wire hole, and the second end cap has a second wire hole. Both the first wire hole and the second wire hole are in communication with the wire channel.

[0014] Based on the aforementioned technical means, the first and second end caps, along with the first and second wiring holes, are respectively connected to the wiring channel. The wire harness enters through the first wiring hole, passes through the wiring channel inside the installation channel, and exits through the second wiring hole. This prevents multiple wire harnesses from tangling and crossing at the ports of the installation channel, ensuring a clear wire harness path and facilitating later maintenance and organization. Furthermore, the first and second end caps cover both ends of the installation channel, preventing dust, moisture, or foreign objects from entering the installation channel and avoiding impurities adhering to the internal cable connectors. This reduces the risk of short circuits, poor contact, and other faults, increasing protective performance. Moreover, the first and second end caps are detachably connected to the housing. When it is necessary to replace the cable or repair the internal connector, only the first or second end cap needs to be removed to expose the port and installation channel without damaging the overall structure. This simple and convenient operation reduces maintenance costs.

[0015] In some embodiments, one of the housing and the first end cap is provided with a second snap-fit ​​hole, and the other of the housing and the first end cap is provided with a second snap-fit ​​protrusion, which snaps into the second snap-fit ​​hole.

[0016] According to the above-mentioned technical means, the housing and the first end cap can be fixed by means of the second snap-fit ​​hole and the second snap-fit ​​protrusion, without the need for tools or other auxiliary parts. It is not easily loosened without strong external force, ensuring that the end cap always tightly covers the housing port. During assembly, simply aligning the second snap-fit ​​hole and the second snap-fit ​​protrusion is sufficient to connect the end cap and the housing; during disassembly, pressing the second snap-fit ​​protrusion separates them. The operation is simple and quick, shortening installation and maintenance time.

[0017] In some embodiments, the device further includes a first seal and a second seal. The first seal is disposed within the mounting channel and located on one side of the fixing member in the axial direction of the mounting channel, and the second seal is disposed within the mounting channel and located on the other side of the fixing member in the axial direction of the mounting channel. The first seal and the second seal are used to seal the gap between the mounting channel and the wire harness.

[0018] Based on the above technical means, by setting the first sealing element and the second sealing element, the gap between the wire harness and the installation channel can be sealed; the sealing element can block external moisture, dust and other substances, effectively reducing the risk of short circuits, corrosion and poor contact caused by pollution of internal cables and joints.

[0019] In some embodiments, a wire clip is also included, which is disposed between the first end cap and the housing and is used to surround the wire harness. The wire clip includes a body and a plurality of elastic parts arranged circumferentially along the mounting channel. The plurality of elastic parts are all connected to the body. The first end cap is provided with a groove, and the plurality of elastic parts are located in the groove. The inner wall surface of the groove is used to hold the plurality of elastic parts tightly on the wire harness.

[0020] Based on the aforementioned technical means, on the one hand, the wire clip is equipped with multiple elastic parts. When facing wire harnesses of different diameters, the elastic parts can adjust their opening range through their own deformation to achieve wrapping around wire harnesses of different specifications. At the same time, the inner wall of the groove of the first end cap will press the elastic parts towards the wire harness. Regardless of the thickness of the wire harness, the elastic parts can tightly fit the outer surface of the wire harness through deformation, improving the overall adaptability. On the other hand, the multiple elastic parts of the wire clip can be fixed in a circumferential manner around the wire harness. The inner wall of the groove of the first end cap continuously applies pressure to the elastic parts, forming a stable clamping force, which can prevent the wire harness from loosening in the installation channel, thereby preventing friction and wear between the wire harness and the inner wall of the installation channel, and reducing problems such as poor internal contact or loosening at the joint due to wire harness displacement.

[0021] In some embodiments, a connector is also included for connecting to the vehicle body, the connector being connected to the housing and having an adjustable position on the housing.

[0022] Based on the aforementioned technical means, different vehicle body structures vary. Even for the same vehicle model, the actual wiring may require adjustments to the fixing position of the junction box due to the wiring harness routing, surrounding components, etc. The position of the connectors can be adjusted, and the junction box can flexibly adjust its fixing point according to the actual installation conditions of the vehicle, thereby further optimizing the routing path of the wiring harness and improving the versatility of the junction box.

[0023] Secondly, embodiments of this application also provide a vehicle body structure, which includes a vehicle body and a junction box as described in the first aspect.

[0024] Since the vehicle body structure provided in this application includes the junction box in the first aspect, it can solve the same technical problems as the junction box described above and achieve the same technical effects, so it will not be described again here.

[0025] Thirdly, embodiments of this application also provide a vehicle that includes the body structure described in the second aspect above.

[0026] Since the vehicle provided in this application includes the body structure in the second aspect, it can solve the same technical problems as the above-mentioned body structure and achieve the same technical effects, it will not be described again here. Attached Figure Description

[0045] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0046] Please see Figures 1-2 This application provides a vehicle. The vehicle can be a pure electric vehicle, a range-extended electric vehicle, a hybrid electric vehicle, a fuel cell electric vehicle, or a hydrogen engine vehicle, etc.

[0047] In some embodiments, the vehicle includes a body structure, which includes a body body. The body body includes a cockpit and a frame structure that encloses a passenger compartment. The body body may also have a seat mounting structure, seats, etc.

[0048] In some embodiments, the vehicle body structure may also include a junction box 100, which is used to rationally distribute the power from the battery and generator to various electrical devices such as motors, headlights, windshield wipers, air conditioners, and audio systems. The junction box 100 is typically installed in spaces such as the rear of the driver's cabin, inside the chassis frame, or under the trunk.

[0049] In some examples, the junction box 100 can be a vehicle high-voltage wiring harness junction box, an industrial junction box, a furniture junction box, etc., and this application does not specifically limit it. This application is illustrated by using the junction box 100 in a vehicle as an example.

[0050] In some embodiments, the junction box 100 includes a housing 110 and a fixing member 120. The housing 110 includes two mounting channels. The wire harness enters from one end of the mounting channel and exits from the other end of the mounting channel in two separate parts. The fixing member 120 includes a first fixing structure 121 and a second fixing structure 122. The structures of the first fixing structure 121 and the second fixing structure 122 are detachably connected to the structure of the mounting channel. The mounting channel can be divided into two parts. That is, when two wire harnesses enter from the first fixing structure 121 and the second fixing structure 122 respectively, the wire harnesses that are split off at the other end of the two wire harnesses exit through the split points of the first fixing structure 121 and the second fixing structure 122 respectively. The first fixing structure 121 and the second fixing structure 122 are detachably connected and define the wire passage. The wire passage is used to pass the wire harness. The fixing member 120 is disposed in the mounting channel and is engaged with the housing 110. The first fixing structure 121 and the second fixing structure 122 form a wire-passing channel, which can effectively prevent the wire harness from shifting or loosening during use. At the same time, the first fixing structure 121 and the second fixing structure 122 are detachably connected without the need for additional fixing parts 120, which can achieve quick assembly and disassembly, facilitating the later layout and maintenance of the wire harness. Furthermore, the engagement of the fixing part 120 with the housing 110 further enhances the overall structural strength of the junction box 100.

[0051] In some examples, the first fixing structure 121 and the second fixing structure 122 are threaded together, and the assembly of the first fixing structure 121 and the second fixing structure 122 can be completed with only common tools such as screwdrivers, which reduces the production cost of the junction box 100.

[0052] In some examples, the first fixing structure 121 and the second fixing structure 122 can also be a snap-fit ​​connection, which will not be described in detail here.

[0053] In some examples, both the first fixing structure 121 and the second fixing structure 122 are L-shaped plate structures, which enclose a wire-passing channel, thus defining the installation channel as a two-part structure.

[0054] In some other examples, the first fixing structure 121 and the second fixing structure 122 can also be block structures, as long as they can achieve the snap-fit ​​effect on the wire harness, which will not be described in detail here.

[0055] In some embodiments, one of the first fixing structure 121 and the second fixing structure 122 is provided with a first snap-fit ​​hole 1231, and the other of the first fixing structure 121 and the second fixing structure 122 is provided with a first snap-fit ​​protrusion 124, which snaps into the first snap-fit ​​hole 1231. The first snap-fit ​​protrusion 124 and the first snap-fit ​​hole 1231 can be quickly positioned and locked, and assembly and disassembly can be completed without tools, further improving the portability of the junction box 100.

[0056] This application is illustrated by way of example, with a first snap-fit ​​hole 1231 provided on the first fixing structure 121 and a first snap-fit ​​protrusion 124 provided on the second fixing structure 122.

[0057] In some examples, the first fixing structure 121 is provided with a first snap-fit ​​hole 1231, which is circular, and the second fixing structure 122 is provided with a first snap-fit ​​protrusion 124, which is cylindrical. The first snap-fit ​​protrusion 124 snaps into the snap-fit ​​hole. The wall of the first snap-fit ​​hole 1231 is smoothed to ensure the structural strength of the first snap-fit ​​hole 1231 and to provide smooth guidance for the subsequent snap-fit ​​of the first snap-fit ​​protrusion 124. The first snap-fit ​​protrusion 124 is integrally formed on the second fixing structure 122. The outline of the first snap-fit ​​protrusion 124 is adapted to the first snap-fit ​​hole 1231. The end of the first snap-fit ​​protrusion 124 is an arc protrusion, which facilitates the insertion of the first snap-fit ​​protrusion 124 into the first snap-fit ​​hole 1231 to form an effective snap-fit.

[0058] During assembly, the first snap-fit ​​protrusion 124 snaps into the first snap-fit ​​hole 1231, allowing for manual connection without the need for additional tools, thus improving assembly efficiency. The engagement between the first snap-fit ​​protrusion 124 and the first snap-fit ​​hole 1231 restricts the displacement of the first fixing structure 121 and the second fixing structure 122, reducing the occurrence of loosening. When maintenance is required, the first snap-fit ​​protrusion 124 and the first snap-fit ​​hole 1231 can be separated by appropriate external force, facilitating later maintenance and modification.

[0059] In some examples, the first snap-fit ​​hole 1231 can be a dovetail groove, and the first snap-fit ​​protrusion 124 is a wedge-shaped structure. During installation, it is pushed in along the inclined surface to achieve automatic locking of the first fixing structure 121 and the second fixing structure 122. During disassembly, it can be slid out along the dovetail groove to complete the separation of the first fixing structure 121 and the second fixing structure 122.

[0060] In some other examples, both the first snap-fit ​​hole 1231 and the first snap-fit ​​protrusion 124 are rectangular structures. Thus, by snapping the first snap-fit ​​protrusion 124 into the first snap-fit ​​hole 1231, the first fixing structure 121 and the second fixing structure 122 can be quickly assembled and disassembled.

[0061] In some embodiments, one of the first fixing structure 121 and the second fixing structure 122 has a protrusion 123 protruding toward the other, and a first snap-fit ​​hole 1231 is provided on the protrusion 123 and extends along a first direction X, which is perpendicular to the arrangement direction of the first fixing structure 121 and the second fixing structure 122. The arrangement direction of the first fixing structure 121 and the second fixing structure 122 is the second direction Y. The other of the first fixing structure 121 and the second fixing structure 122 has a first snap-fit ​​protrusion 124 protruding along the first direction X. For example, the first snap-fit ​​protrusion 124 is provided on the side surface of the other of the first fixing structure 121 and the second fixing structure 122 facing the protrusion 123, so that the first snap-fit ​​protrusion 124 can be easily snapped into the first snap-fit ​​hole 1231.

[0062] Since the first snap-fit ​​hole 1231 extends along the first direction X and the first snap-fit ​​protrusion 124 protrudes along the first direction X, after the first snap-fit ​​protrusion 124 extends into the first snap-fit ​​hole 1231, the first snap-fit ​​hole 1231 can limit the first snap-fit ​​protrusion 124 in the arrangement direction of the first fixing structure 121 and the second fixing structure 122, so as to effectively prevent the first snap-fit ​​protrusion 124 and the second snap-fit ​​protrusion 124 from separating, thereby improving the stability of the connection between the first fixing structure 121 and the second fixing structure 122. During assembly, it is only necessary to align the first fixing structure 121 and the second fixing structure 122 and insert the first snap-fit ​​protrusion 124 into the first snap-fit ​​hole 1231 to complete the fixation. The assembly is simple and quick.

[0063] This application is illustrated by way of example, with a protrusion 123 provided on the first fixing structure 121 and a first snap-fit ​​protrusion 124 provided on the second fixing structure 122.

[0064] In some examples, the first fixing structure 121 has a protrusion 123, which is rectangular in shape and is a mounting plate extending along the first direction X. A first snap-fit ​​hole 1231 is provided on the mounting plate, which is rectangular in shape and matches the rectangular protrusion 123. The second fixing structure 122 has a first snap-fit ​​protrusion 124. The part of the outer peripheral surface of the second fixing structure 122 that mates with the mounting plate is provided with a mounting groove, and the first snap-fit ​​protrusion 124 is provided in the mounting groove.

[0065] The mounting plate provides a stable bearing base for the first snap-fit ​​hole 1231, enhancing the structural strength of the snap-fit ​​part and reducing deformation under stress. The first snap-fit ​​protrusion 124 of the second fixing structure 122 is located in the mounting groove. The mounting groove can form a certain enclosure and limit for the first snap-fit ​​protrusion 124, preventing accidental deformation of the first snap-fit ​​protrusion 124 due to external force collisions. At the same time, during snap-fit ​​engagement, the mounting groove and mounting plate can guide the first snap-fit ​​protrusion 124 to accurately align with the first snap-fit ​​hole 1231, improving the fit accuracy and reducing shaking. The mounting plate provides a clear operating area for snap-fit ​​operations, making it easy for operators to observe and align the first snap-fit ​​hole 1231 and the first snap-fit ​​protrusion 124, improving installation efficiency. During disassembly, it also provides a certain amount of space for tools or hand operations, facilitating the separation of the first fixing structure 121 and the second fixing structure 122, making the disassembly process smoother.

[0066] In other examples, the protrusion 123 can also be circular, triangular, etc., as long as it can achieve the snap-fit ​​of the first fixing structure 121 and the second fixing structure 122. These will not be described in detail here.

[0067] In some embodiments, the junction box 100 further includes a first end cover 131 and a second end cover 132. The first end cover 131 covers one end port of the mounting channel and is detachably connected to the housing 110. The second end cover 132 covers the other end port of the mounting channel and is detachably connected to the housing 110. The first end cover 131 is provided with a first wire hole 1311, and the second end cover 132 is provided with a second wire hole 1321. Both the first wire hole 1311 and the second wire hole 1321 are in communication with the wire channel.

[0068] The first through hole 1311 and the second through hole 1321 are respectively connected to the wiring channel. The wire harness enters from the first through hole 1311, passes through the wiring channel inside the installation channel, and exits from the second through hole 1321. This avoids multiple wire harnesses from tangling and crossing at the port of the installation channel, ensuring a clear wire harness route and facilitating later maintenance and organization. Furthermore, the first end cap 131 and the second end cap 132 cover both ends of the installation channel, preventing dust, moisture, or foreign objects from entering the installation channel. This prevents impurities from adhering to the internal cable connectors, reducing the risk of short circuits, poor contact, and other faults, and increasing protection performance. Moreover, the first end cap 131 and the second end cap 132 are detachably connected to the housing 110. When it is necessary to replace the cable or repair the internal connector, only the first end cap 131 or the second end cap 132 needs to be removed to expose the port and the installation channel without damaging the overall structure. This simple and convenient operation reduces maintenance costs.

[0069] In some embodiments, one of the housing 110 and the first end cap 131 is provided with a second snap-fit ​​hole 142, and the other of the housing 110 and the first end cap 131 is provided with a second snap-fit ​​protrusion 141, which snaps into the second snap-fit ​​hole 142. The housing 110 and the first end cap 131 can be fixed by the second snap-fit ​​hole 142 and the second snap-fit ​​protrusion 141 without the need for tools or other auxiliary parts, and are not easy to loosen without strong external force, ensuring that the first end cap 131 always tightly covers the port of the housing 110. During assembly, it is only necessary to align the positions of the second snap-fit ​​hole 142 and the second snap-fit ​​protrusion 141 to complete the connection between the first end cap 131 and the housing 110; during disassembly, it can be separated by pressing the second snap-fit ​​protrusion 141, which is simple and quick to operate and shortens the installation and maintenance time.

[0070] This application is illustrated by way of example, with a second snap-fit ​​hole 142 on the housing 110 and a second snap-fit ​​protrusion 141 on the first end cover 131.

[0071] In some examples, the outer circumferential surface of the housing 110 is evenly provided with multiple second snap-fit ​​holes 142, and the first end cap 131 is correspondingly provided with multiple second snap-fit ​​protrusions 141. During installation, no tools are required; assembly can be completed manually. After aligning the second snap-fit ​​protrusions 141 with the second snap-fit ​​holes 142, a pushing force is applied, and the second snap-fit ​​protrusions 141 are inserted into the second snap-fit ​​holes 142 to complete the fixation. During disassembly, the second snap-fit ​​protrusions 141 are pressed in the opposite direction to separate the two, significantly shortening the assembly and disassembly time. The multiple second snap-fit ​​holes 142 and the second snap-fit ​​protrusions 141 are evenly distributed along the outer circumferential surface, which can distribute the connection force between the first end cap 131 and the housing 110 to multiple points, avoiding excessive force at a single point that could lead to deformation or loosening.

[0072] In other examples, multiple threaded holes are evenly distributed on the edges of the first end cap 131 and the second end cap 132, and the housing 110 is provided with threaded holes of the same specification at corresponding positions. Bolts or screws are inserted through the threaded holes and the threaded holes to fasten the first end cap 131 and the second end cap 132 to the housing 110. During later maintenance, the parts can be disassembled simply by unscrewing the bolts.

[0073] In some other examples, permanent magnets are embedded in the ports of the housing 110, and the first end cap 131 and the second end cap 132 are made of ferromagnetic materials (or have corresponding magnets embedded in them). They are connected by magnetic attraction and can be separated by applying a certain external force when disassembled.

[0074] In some embodiments, the connection method between the second end cap 132 and the housing 110 can be the same as the connection method between the first end cap 131 and the housing 110 in any of the above embodiments, and will not be described in detail here.

[0075] In some embodiments, the junction box 100 further includes a first seal 151 and a second seal 152. The first seal 151 is disposed within the mounting channel and located on one side of the fixing member 120 along the axial direction of the mounting channel. The second seal 152 is disposed within the mounting channel and located on the other side of the fixing member 120 along the axial direction of the mounting channel. The first seal 151 and the second seal 152 are used to seal the gap between the mounting channel and the wire harness. The first seal 151 and the second seal 152 can seal the gap between the wire harness and the mounting channel; the seals can block external moisture, dust, etc., effectively reducing the risk of short circuits, corrosion, poor contact, etc., caused by contamination of internal cables and connectors.

[0076] In some examples, the first seal 151 and the second seal 152 are sealing rings. The sealing rings form a sealing barrier in the installation channel. The sealing rings are positioned with the support of the housing 110 structure and can also provide all-round coverage of the gaps in the installation channel. For moisture in the external environment, whether it is direct splashing of liquid water or moisture penetration in a high humidity environment, the sealing rings can fill the tiny gaps between the wire harness and the channel wall through their own elastic deformation, forming a water-impermeable physical barrier to prevent moisture from seeping into the installation channel along the gaps.

[0077] In some examples, the sealing ring can be a rubber sealing ring, a metal sealing ring, a plastic sealing ring, etc., which will not be described in detail here.

[0078] In some embodiments, the junction box 100 further includes a wire clip 160 disposed between the first end cap 131 and the housing 110, and the wire clip 160 is used to surround the wire harness for securing the wire harness. The wire clip 160 includes a body and a plurality of elastic portions 161 arranged circumferentially along the mounting channel. The plurality of elastic portions 161 are all connected to the body. For example, the elastic portions 161 can be sheet-like structures or rod-like structures. The first end cap 131 is provided with a groove 133, and the plurality of elastic portions 161 are located in the groove 133. The inner wall surface of the groove 133 is used to hold the plurality of elastic portions 161 tightly onto the wire harness.

[0079] Specifically, after the multiple elastic parts 161 are located within the groove 133 of the first end cap 131, the inner wall of the groove 133 of the first end cap 131 limits the multiple elastic parts 161, causing the multiple elastic parts 161 to contract towards the wire harness and compress the wire harness in the direction of the elastic parts 161. Regardless of the thickness of the wire harness, the elastic parts 161 can tightly fit the outer surface of the wire harness through deformation, improving the overall adaptability. The multiple elastic parts 161 of the wire clip 160 can be fixed in a circumferential manner around the wire harness. The inner wall of the groove 133 of the first end cap 131 continuously applies pressure to the elastic parts 161, forming a stable clamping force, which can prevent the wire harness from loosening in the installation channel, thereby preventing friction and wear between the wire harness and the inner wall of the installation channel, and also reducing the problem of poor internal contact or loosening at the joint due to the displacement of the wire harness.

[0080] In some examples, in addition to being arranged circumferentially along the mounting channel, multiple elastic portions 161 may have protrusions added to their inner surfaces. When the inner wall of the groove 133 presses against the elastic portion 161, the protrusions can press against the outer protective layer of the wire harness to increase the clamping force on the wire harness and prevent the wire harness from sliding in the axial direction.

[0081] In some embodiments, the junction box 100 further includes a connector 170 for connecting to the vehicle body. The connector 170 is connected to the housing 110 and its position on the housing 110 is adjustable. Different vehicle body structures vary, and even for the same vehicle model, the fixed position of the junction box 100 may need to be adjusted due to interference from wiring harness routing and surrounding components. By adjusting the position of the connector 170 on the housing 110, the junction box 100 can flexibly adjust its fixing point according to the actual installation conditions of the vehicle body, thereby further optimizing the routing path of the wiring harness and improving the versatility of the junction box 100.

[0082] In some examples, the connector 170 can be connected to the housing 110 via a slide rail slider structure, allowing the position of the connector 170 on the housing 110 to be adjusted by the relative sliding of the slide rail and slider. In some examples, limit blocks can also be provided at both ends of the slide rail to limit the slider and prevent it from falling off. In some examples, a locking bolt can also be provided on the slider. After the position of the connector 170 on the housing 110 is adjusted to the correct position, the locking bolt can be tightened to abut against the slide rail, thereby fixing the slider to the slide rail and preventing the connector 170 from moving relative to the housing 110.

[0083] In other examples, the connector 170 may be provided with multiple slots, and the housing 110 may be provided with a resilient latch. The position of the connector 170 on the housing 110 can be adjusted by engaging the resilient latch with different slots, thus allowing for tool-free adjustment and convenient operation.

[0084] In some embodiments, the connector 170 can be an elastic clip, which engages with the clip hole on the vehicle body to fix the junction box 100 on the vehicle body.

[0085] In other embodiments, the connector 170 may also be a connector plate with connector holes, and the junction box 100 may be fixed on the vehicle body by fasteners such as bolts and pins passing through the connector holes on the connector plate and the connector holes on the vehicle body.
