Description

Technical Field

[0001] This utility model relates to the field of air conditioning wiring harness arrangement technology, and in particular to a wiring harness connection device and a heat exchange device. Background Technology

[0002] With the rapid development of electrochemical energy storage technology, the requirements for heat dissipation of the battery cells in energy storage systems are becoming increasingly stringent. Air-cooled, door-mounted integrated air conditioners have become a crucial temperature control device for containerized energy storage systems. In related technologies, the air conditioner's control box is connected to the outdoor unit via an air conditioning wiring harness. Waterproof terminals are installed on both the indoor and outdoor sides to address waterproofing issues; however, the control box is secured internally with sealant.

[0003] In a wind-cooled, door-mounted integrated air conditioner, both the indoor and outdoor sides are integrated into one unit, with the outdoor side exposed to the environment. The indoor and outdoor sides are separated only by a single sheet metal frame, resulting in a very close physical distance. Wiring harnesses need to be routed through these frames to connect the indoor and outdoor sides. These wiring harness routes require waterproof sealing; otherwise, moisture from the outdoor side will enter the indoor side, causing electrical components to malfunction. Therefore, the wiring harnesses connecting the indoor and outdoor sides all need to be waterproofed, leading to complex sealing methods and potentially poor reliability.

[0004] Therefore, ensuring that the connection points of the air conditioning wiring harness are waterproof and sealed during the connection process is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a wiring harness connection device and a heat exchange equipment that can quickly connect the outdoor wiring harness and the indoor wiring harness of an air conditioner while meeting waterproof requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wire harness connection device includes a wire harness connection end and a wire harness assembly end. The wire harness assembly end includes an assembly end housing. A first assembly portion and a second assembly portion are provided on both sides of the assembly end housing. The second assembly portion is detachably connected to the wire harness connection end. The wire harness connection end has a cavity for inserting the second assembly portion. The assembly end housing has a stop surface. At least one of the end face of the cavity and the stop surface has a sealing ring. An anti-detachment positioning groove is provided on the cavity, and an anti-detachment positioning platform is provided on the wire harness assembly end. The anti-detachment positioning groove and the anti-detachment positioning platform are detachably interference-fitted.

[0008] When the wire harness connection end is engaged with the wire harness assembly end, the anti-detachment positioning groove and the anti-detachment positioning platform lock the wire harness assembly end and drive the end face and the stop surface to press the sealing ring together to seal the cavity.

[0009] On the other hand, the wire harness connection end includes a connection end housing, and the connection end housing has a first connection portion and a second connection portion on both sides.

[0010] The periphery of the connecting end housing is provided with a limiting connecting surface, and the second connecting part protrudes from the limiting connecting surface; the connecting end housing is fixed on the partition so that the limiting connecting surface fits with the surface of the partition, and the second connecting part passes through the partition from the outdoor side to the indoor side and is detachably connected to the indoor side wiring harness.

[0011] On the other hand, the periphery of the connecting end housing is provided with a limiting step, the limiting connecting surface is located on the side of the limiting step near the second connecting part, and the limiting step is provided with a connecting hole for cooperating with the separator.

[0012] On the other hand, it also includes fasteners, which pass through the connecting hole and are connected to the separator.

[0013] On the other hand, the number of connecting holes is at least two, and they are symmetrically distributed relative to the second connecting part.

[0014] On the other hand, the first connecting part is provided with a plurality of foot holes, and a sealing structure is provided in the foot holes. Each cable in the outdoor wiring harness is fixed through one of the foot holes to achieve communication with the second connecting part.

[0015] On the other hand, it also includes a sealing component for sealing off unused foot holes, the sealing component being adapted to the size of the foot holes.

[0016] On the other hand, one of the connecting end housing and the assembly end housing is provided with a buckle, and the other is provided with a slot. The buckle and the slot can be engaged along the assembly direction of the connecting end housing and the assembly end housing.

[0017] On the other hand, when the buckle engages with the slot, the end face of the cavity presses against the stop face to seal the sealing ring.

[0018] This utility model also provides a heat exchange device, including the above-mentioned wire harness connection device.

[0019] The wire harness connection device provided by this utility model includes a wire harness connection end and a wire harness assembly end.

When the wire harness connection end and the wire harness assembly end are engaged, the anti-detachment positioning groove and the anti-detachment positioning platform lock the wire harness assembly end and drive the end face and the stop surface to press the sealing ring to seal the cavity. The wire harness connection device provided by this utility model connects the indoor wire harness to the wire harness connection end by connecting the wire harness assembly end to the indoor wire harness, thereby enabling the indoor wire harness to conduct electricity with the outdoor wire harness. By providing a cavity on the wire harness connection end, when the wire harness connection end and the wire harness assembly end are assembled, the second assembly part of the wire harness assembly end is inserted into the cavity of the wire harness connection end. Then, the sealing ring between the stop surface of the assembly end housing and the end face of the cavity is used to seal the cavity, thus achieving a sealing effect between the wire harness assembly end and the wire harness connection end on the indoor side. This eliminates the need for adhesive sealing on the indoor side, effectively preventing connection failure due to water accumulation or dampness on the indoor side, and improving the connection reliability. Simultaneously, the interference fit between the anti-detachment positioning groove and the anti-detachment positioning platform locks the wire harness connection end and the wire harness assembly end together, driving the end face to press against the stop surface to seal the cavity and ensure a sealing effect.

[0020] The heat exchange equipment provided by this utility model is equipped with the above-mentioned wire harness connection device.

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.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

The wiring harness connection end 100 is used to connect to the outdoor wiring harness 001, and the wiring harness assembly end 200 is used to connect to the indoor wiring harness 002. The wiring harness connection end 100 and the wiring harness assembly end 200 are detachably connected. Specifically, the wiring harness connection end 100 can be a female end, and the wiring harness assembly end 200 can be a male end. Of course, depending on the different chassis and usage scenarios, the wiring harness connection end 100 can also be set to be a male end, and the wiring harness assembly end 200 to be a female end. The specific configuration can be determined as needed. Please refer to [reference needed]. Figure 3-1 and Figure 3-2 On the indoor side, the structure of the wire harness assembly end 200 can be seen, and on the outdoor side, the structure of the wire harness connection end 100 can be seen.

[0039] For further information, please refer to [link / reference]. Figures 2-1 to 2-3The wiring harness assembly end 200 includes an assembly end housing 210, on which a first assembly portion 220 and a second assembly portion 230 are provided. The first assembly portion 220 and the second assembly portion 230 are respectively located on both sides of the assembly end housing 210. The first assembly portion 220 is used to connect with the indoor wiring harness 002, and the second assembly portion 230 is detachably connected to the wiring harness connection end 100 to conduct or disconnect the indoor wiring harness 002 from the outdoor wiring harness 001. Specifically, the second assembly portion 230 is detachably connected to the second connection portion 130 of the wiring harness connection end 100. Similarly, the first assembly portion 220 and the second assembly portion 230 are distributed along a first direction, and the first assembly portion 220 and the second assembly portion 230 are respectively located on both sides of the assembly end housing 210. Located on both sides of the assembly end housing 210 along the first direction; the first assembly part 220 and the indoor side wiring harness 002 can be fixedly connected to ensure the stability of the connection between the first assembly part 220 and the indoor side wiring harness 002; the assembly end housing 210, the first assembly part 220 and the second assembly part 230 can be an integrally formed structure, which is convenient for processing and has a stable structure; the first assembly part 220 is fixedly connected to the indoor side wiring harness 002 to ensure the stability of the indoor side wiring harness 002, and the indoor side wiring harness 002 is finally connected to the second assembly part 230. The second assembly part 230 can be provided with probes and other structures to facilitate connection and connection with the wiring harness connection end 100, thereby realizing the connection between the indoor side wiring harness 002 and the indoor side wiring harness 002.

[0040] Furthermore, the wire harness connection end 100 is provided with a cavity 150 for the second assembly part 230 to be inserted, the assembly end housing 210 is provided with a stop surface, and a sealing structure is provided between the end face 151 of the cavity 150 and the stop surface, so as to seal the cavity 150 after the wire harness connection end 100 and the wire harness assembly end 200 are fastened together; furthermore, at least one of the end face 151 of the cavity 150 and the stop surface is provided with a sealing ring to form a sealing structure.

[0041] In some embodiments, one of the connecting end housing 110 and the assembly end housing 210 is provided with an anti-detachment positioning groove 111, and the other is provided with an anti-detachment positioning platform 211. The anti-detachment positioning groove 111 and the anti-detachment positioning platform 211 are detachably interference-fitted. When the wire harness connecting end 100 and the wire harness assembly end 200 are engaged, the anti-detachment positioning groove 111 and the anti-detachment positioning platform 211 lock the wire harness connecting end 100 and the wire harness assembly end 200, and drive the end face 151 and the stop face to press the sealing ring to seal the cavity 150. Specifically, at least one of the anti-detachment positioning groove 111 and the anti-detachment positioning platform 211 can be provided with an elastic layer, such as a rubber layer. By providing the anti-detachment positioning groove 111 and the anti-detachment positioning platform 211, the wire harness connecting end 100 and the wire harness assembly end 200 can be prevented from detaching. They can only be separated when subjected to external force.

[0042] Furthermore, there are at least two anti-detachment positioning slots 111 and anti-detachment positioning platforms 211, and they are matched one-to-one. By setting the anti-detachment positioning slots 111 and anti-detachment positioning platforms 211, not only can the wire harness connection end 100 be prevented from detaching from the wire harness assembly end 200, but the connection end housing 110 and the assembly end housing 210 can also be effectively prevented from being installed in reverse, thus achieving a foolproof effect and ensuring installation accuracy.

[0043] This wiring harness connection device connects the indoor wiring harness 002 to the wiring harness connection end 100 via the wiring harness assembly end 200, thereby enabling the indoor wiring harness 002 to conduct electricity with the outdoor wiring harness 001. Because the wiring harness connection end 100 has a cavity 150, when the wiring harness connection end 100 and the wiring harness assembly end 200 are assembled, the second assembly part 230 of the wiring harness assembly end 200 is inserted into the cavity 150 of the wiring harness connection end 100, and then, by means of… The sealing structure between the stop surface of the assembly end housing 210 and the end face 151 of the cavity 150 achieves a sealing setting of the cavity 150, thereby achieving a sealing effect between the wire harness assembly end 200 and the wire harness connection end 100 on the indoor side. There is no need to perform glue sealing treatment on the indoor side, which effectively avoids the connection failure between the wire harness connection end 100 and the wire harness assembly end 200 when there are problems such as water accumulation and humidity on the indoor side, thus improving the connection reliability between the wire harness connection end 100 and the wire harness assembly end 200.

[0044] In some embodiments, the wiring harness connection end 100 is used to connect the outdoor wiring harness 001 and the indoor wiring harness 002, and includes a connection end housing 110. The connection end housing 110 is provided with a first connection portion 120 and a second connection portion 130, which are respectively located on both sides of the connection end housing 110. The first connection portion 120 is used to connect with the outdoor wiring harness 001. The periphery of the connection end housing 110 is provided with a limiting connection surface 141. The connection end housing 110 is fixed on the partition 300, and the second connection portion 130 protrudes from the limiting connection surface 141. The connection end housing 110 can be fixed on the partition 300 between the indoor side and the outdoor side so that the limiting connection surface 141 fits with the surface of the partition 300, and the second connection portion 130 passes through the partition 300 from the outdoor side to the indoor side and is detachably connected to the indoor wiring harness 002.

[0045] Specifically, the first connecting portion 120 and the second connecting portion 130 are distributed along a first direction, and the first connecting portion 120 and the second connecting portion 130 are respectively located on both sides of the connecting end housing 110 along the first direction, which is perpendicular to the separator 300; the first connecting portion 120 can be optionally fixedly connected to the outdoor side wiring harness 001 to ensure the stability of the connection between the first connecting portion 120 and the outdoor side wiring harness 001; the connecting end housing 110, the first connecting portion 120, and the second connecting portion 130 can be an integrally formed structure, which is convenient for processing and has a stable structure; the first connecting portion 120 may be provided with The foot hole 121 is connected to the outdoor side wiring harness 001. The outdoor side wiring harness 001 is connected to the second connection part 130 through the first connection part 120. The second connection part 130 can be provided with a metal conductive structure to facilitate connection and conduction with the indoor side wiring harness 002, thereby realizing the conduction between the outdoor side wiring harness 001 and the indoor side wiring harness 002. The wiring harness assembly end 200 can be provided on the indoor side wiring harness 002, and the wiring harness assembly end 200 can be used to assemble with the second connection part 130. Alternatively, the indoor side wiring harness 002 can be connected to the second connection part 130 through other means.

[0046] Furthermore, the limiting connection surface 141 should be perpendicular to the first direction, that is, after the connecting end housing 110 is installed on the partition 300, the limiting connection surface 141 is parallel to the surface of the partition 300; the second connecting part 130, by protruding from the limiting connection surface 141, can have sufficient size to connect with the indoor side wiring harness 002 after passing through the partition 300, which is convenient for assembly.

[0047] Furthermore, the outdoor wiring harness 001 and the indoor wiring harness 002 can be configured with branch starting points based on the different locations of the device 003, such as... Figure 4-1 and Figure 4-2 As shown, it is possible to constrain the cables on the indoor and outdoor sides to form a cable harness.

[0048] The above configuration, by mounting the connecting end housing 110 on the partition 300, allows the second connecting part 130 to pass through the partition 300 from the outdoor side and enter the indoor side, where it is detachably connected to the indoor side wiring harness 002. The first connecting part 120 is located on the outdoor side of the partition 300 and is connected to the outdoor side wiring harness 001. By providing a limiting connecting surface 141 on the connecting end housing 110, and by utilizing the limiting connecting surface 141 to fit against the surface of the partition 300, moisture from the outdoor side is effectively prevented from entering the indoor side, thereby achieving a waterproof effect, reducing the use of sealant, facilitating installation, and ensuring reliable waterproof performance. Furthermore, the detachable connection between the second connecting part 130 and the indoor side wiring harness 002 facilitates the assembly and disassembly of the indoor side wiring harness 002 and the outdoor side wiring harness 001, improving assembly and disassembly efficiency.

[0049] In some embodiments, the periphery of the connecting end housing 110 is provided with a limiting step 140, and a limiting connecting surface 141 is located on the side of the limiting step 140 near the second connecting part 130. The limiting step 140 is provided with a connecting hole 142 for cooperating with the separator 300. The limiting step 140 and the connecting end housing 110 are integral structures. The limiting step 140 is provided to facilitate fixing with the separator 300. The shape and size of the limiting step 140 can be set according to the shape and size of the second connecting part 130. The limiting step 140 should be at least set such that the limiting connecting surface 141 is arranged around the periphery of the second connecting part 130, that is, the entire circumference of the second connecting part 130 is surrounded by the limiting connecting surface 141, thereby ensuring that the limiting connecting surface 141 can better seal the gap between the second connecting part 130 and the separator 300. A sealing layer, such as an elastic structure like rubber, can also be provided on the surface of the limiting connection surface 141 to further improve the fit between the limiting connection surface 141 and the separator 300.

[0050] In some embodiments, a fastener is also included, which passes through the connecting hole 142 and engages with the separator 300. The fastener can be a bolt, which facilitates the assembly and disassembly of the connecting end housing 110, and provides a firm connection and is readily available.

[0051] In some embodiments, the number of connecting holes 142 is at least two, and they are symmetrically distributed relative to the second connecting portion 130. Specifically, connecting holes 142 can be provided on both the left and right sides of the second connecting portion 130, or connecting holes 142 can be provided on the upper and lower sides of the second connecting portion 130. Of course, they can be set as needed. The symmetrical distribution of connecting holes 142 relative to the second connecting portion 130 can ensure that the force on the connecting end housing 110 is uniform, and ensure that the limiting connecting surface 141 and the partition 300 are tightly fitted, avoiding uneven local force, which could cause gaps between the limiting connecting surface 141 and the partition 300.

[0052] In some embodiments, the first connecting portion 120 is provided with a plurality of foot holes 121, and a sealing structure is provided in the foot holes 121. Each cable in the outdoor wiring harness 001 is fixed through a foot hole 121 to achieve communication with the second connecting portion 130. Specifically, the foot hole 121 extends from the side of the first connecting portion 120 away from the second connecting portion 130 to the metal conductive structure of the second connecting portion 130. The foot hole 121 can be part of the metal conductive structure, which facilitates communication between each cable in the outdoor wiring harness 001 and the second connecting portion 130 through the foot hole 121. The foot hole 121 can be part of the metal conductive structure. Furthermore, the foot hole 121 is provided with a sealing structure to seal the cable and the foot hole 121. The sealing structure can be a separately installed sealing ring or a protrusion structure provided on the inner wall of the foot hole 121.

[0053] In some embodiments, a sealing component for sealing an unused foot hole 121 is also included, the sealing component being adapted to the size of the foot hole 121; specifically, the sealing component can be a plastic part, and in order to ensure the sealing effect between the sealing component and the foot hole 121, the sealing component can be a conical structure, with the smaller end of the sealing component inserted into the foot hole 121.

[0054] In some embodiments, the assembly end housing 210 is further provided with a stepped surface 213, which is located between the first assembly part 220 and the second assembly part 230. When the connecting end housing 110 and the assembly end housing 210 are connected, the stepped surface 213 of the assembly end housing 210 will engage with the end face 151 of the connecting end housing 110, thereby limiting the maximum stroke of the assembly end housing 210.

[0055] In some embodiments, the assembly end housing 210 is further provided with a guide boss 214, and the connecting end housing 110 is provided with a guide groove. The guide boss 214 can slide along the guide groove and realize the assembly of the assembly end housing 210 and the connecting end housing 110, until the slot 112 and the buckle 212 engage. The assembly end housing 210 is also provided with a stop surface. After the assembly end housing 210 and the connecting end housing 110 are assembled, the stop surface of the assembly end housing 210 abuts against the connecting end housing 110 to achieve a limit. At the same time, the slot 112 and the buckle 212 engage to prevent the assembly end housing 210 from separating from the connecting end housing 110. When it is necessary to disassemble the assembly end housing 210 and the connecting end housing 110, it is only necessary to press the buckle 212 so that the buckle 212 can be disengaged from the slot 112.

[0056] In some embodiments, one of the connecting end housing 110 and the assembly end housing 210 is provided with a buckle 212 and the other is provided with a slot 112. The buckle 212 and the slot 112 can be engaged along the assembly direction of the connecting end housing 110 and the assembly end housing 210. The assembly direction of the connecting end housing 110 and the assembly end housing 210 is parallel to the first square and perpendicular to the surface of the separator 300.

[0057] In some embodiments, when the buckle 212 engages with the slot 112, the end face 151 of the cavity 150 and the stop surface press the sealing ring together. Specifically, the sealing ring can be arranged around the entire end face 151 of the cavity 150 to ensure the sealing effect. The sealing ring is on one end face 151 of the cavity 150 and the stop surface, and a groove corresponding to the sealing ring is provided on the other end face 151. The end face 151 and the stop surface can press the sealing ring into the groove. By setting the groove, the contact area with the sealing ring can be increased, thereby improving the sealing effect.

[0058] In addition to the aforementioned wire harness connection device, this utility model also provides a heat exchange device including the aforementioned wire harness connection end 100. This heat exchange device includes multiple components 003, a partition 300, and the aforementioned wire harness connection device. The components 003 include indoor-side components and outdoor-side components, which are located on the indoor and outdoor sides of the partition 300, respectively. The wire harness connection device is disposed on the partition 300. Specifically, the partition 300 can be a partition plate, and the partition 300 has mounting holes corresponding to the connection holes 142 of the connection end housing 110. Fasteners pass through the connection holes 142. 42 and mounting holes are provided to fasten the connecting end housing 110 to the partition 300; the partition 300 is also provided with a clearance hole for the second connecting part 130 of the wire harness connecting end 100 to pass through. The size of the clearance hole should not be too large, just enough to allow the second connecting part 130 to pass through, so as to reduce the gap between the clearance hole and the second connecting part 130; the limiting connecting surface 141 can completely cover the clearance hole and the mounting hole, thereby achieving a good waterproof effect; the heat exchange equipment also includes a frame, and the indoor side device, the outdoor side device and the partition 300 are all installed on the frame, and the wire harness connecting device is installed on the partition 300.

[0059] In one specific embodiment, the wire harness connection device provided by this utility model includes the following installation steps:

[0060] Step S1: On the separator 300, according to the dimensions of the connection hole 142 of the wire harness connection end 100 and the second connection part 130, a mounting hole and a clearance hole are made; the holes can be made according to the dimensions of a universal panel-type plug-in waterproof connector.

[0061] Step S2: Design the indoor and outdoor wiring harness 001 scheme. According to the definitions of the connection end housing 110 and the assembly end housing 210, the multiple single-core cables on the indoor side are gathered into the waterproof assembly end housing 210 and wrapped with cloth tape to form the indoor wiring harness 002 assembly. The multiple single-core cables on the outdoor side are gathered into the connection end housing 110 and wrapped with cloth tape to form the outdoor wiring harness 001 assembly. The insulation outer diameter of the outdoor single-core cable needs to meet the wire diameter range required by the waterproof connector. If the pin hole 121 is not used, it needs to be sealed with a corresponding waterproof sealing component to prevent moisture from entering the indoor side through the unused pin hole 121.

[0062] Step S3: Leave the outdoor wiring harness 001 on the outdoor side, fix the connector housing 110 to the separator 300 with screws, and then insert the second assembly part 230 of the wiring harness assembly end 200 into the second connection part 130 of the wiring harness connection end 100. The wiring harness assembly end 200 has a positioning groove. Insert it along the positioning groove until the buckle 212 engages with the slot 112 and a click is heard, which completes the quick connection between the outdoor wiring harness 001 and the indoor wiring harness 002.

[0063] This wire harness connection device solves the problems of difficult, time-consuming, and ineffective waterproofing processes at the wire harness through-holes on the separator 300, improving production efficiency and reducing equipment failures due to poor waterproofing.
