Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to a charging pile charging module assembly cable and its preparation method. Background Technology

[0002] With the development of electric vehicle technology and the increasing popularity of electric vehicles, the number of charging stations in public places has grown rapidly to solve the charging problem, and their functionality is constantly being improved. Among existing charging stations, AC charging stations rely on on-board chargers to convert AC power to DC power, resulting in a slower charging rate. DC charging stations, on the other hand, rely on high-power DC charging modules built into the charging station itself to convert AC power from the grid to DC power before outputting it to the electric vehicle to charge its battery. This charging method offers a higher charging rate, but it also places higher demands on the functionality of the charging stations.

[0003] A utility model patent with authorization announcement number CN212921174U discloses an AC charging pile, including a housing, a door, a control motherboard, a charging gun head, a charging cable, a fingerprint recognition module, wiring terminals, a switching power supply, and a circuit breaker. Its features include: the control motherboard is equipped with an AC contactor, a core board, relay A, a CP signal detection circuit, a CP signal generation circuit, relay B, and relay C; the control motherboard, wiring terminals, switching power supply, and circuit breaker are located inside the housing; the control motherboard is connected to one end of the charging cable via the wiring terminals; the charging gun head is connected to the other end of the charging cable; the circuit breaker input is connected to a power source, and the circuit breaker output is connected to the input of the switching power supply and the contacts of the AC contactor; the switching power supply outputs 12V, 5V, and 3.3V power to power the electrical components of the charging pile.

[0004] As described in the above technical solution, the electrical components are connected by traditional cables. Typically, charging piles are like common power distribution cabinets, with internal cable trays for wiring. However, due to the large number of components inside the charging pile, and the increasing number of wiring harnesses as functions increase, even with the constraints of cable trays, it is still difficult to avoid the problem of messy wiring harnesses, which will affect the convenience of assembly and maintenance. Therefore, it is necessary to improve the existing wiring harness structure of charging piles. Summary of the Invention

[0030] Based on the above technical solutions, preferably, the second electrical terminal includes a conductive rod and an elastic ring, wherein...

[0031] The conductive rod has a stepped structure, with the large-diameter section of the conductive rod supporting the wire and the small-diameter section of the conductive rod penetrating the cover plate and the seal;

[0032] An elastic ring is fitted onto the small-diameter section of the conductive rod, with one end of the elastic ring abutting against the large-diameter section of the conductive rod and the other end abutting against the cover plate.

[0033] Based on the above technical solutions, preferably, the part of the base plate corresponding to the middle section of the wire is a cuttable structure, so that a notch is formed by cutting, so that the middle section of the wire is connected to the external wire and led out to form a third electrical terminal.

[0034] The portion of the cover plate that protrudes and intersects with the first and second slots is provided with a limiting groove, which is used to limit the external wiring in the middle section of the connecting wire.

[0035] Based on the above technical solutions, preferably, the substrate includes a plate and a separator film, wherein,

[0036] There are two panels, and wire channels are set on the opposite surfaces of the two panels, with some wires clamped in the wire channels;

[0037] One isolation membrane is installed on each of the two opposing surfaces of the plates. The portion of the isolation membrane corresponding to the wire groove is bonded to the wire and the wall of the wire groove. The portion of the isolation membrane corresponding to the gap between adjacent wires is bonded to each other and to the plates.

[0038] Based on the above technical solutions, preferably, the substrate further includes a wire frame, and the separator includes a film layer and a retainer, wherein,

[0039] Cable racks are used to connect cables and limit the movement of multiple cables;

[0040] One membrane layer is attached to each side of the wire frame;

[0041] The cage surrounds the membrane layer.

[0042] On the other hand, the present invention provides a method for preparing the above-mentioned charging pile charging module assembly cable, comprising the following steps:

[0043] S1. Prepare the wire, seal the ends of the wire with a cladding layer, and place the wire in a mold;

[0044] S2. The substrate is formed by injection molding, so that the substrate is bonded to the end of the wire;

[0045] S3. A cover plate is formed on the substrate by splicing or injection molding, and then the cover plate is grooved by milling, while the ends of the wires are milled to form exposed parts.

[0046] S4. Connect the end of the lead wire to the exposed part of the wire end by spot welding;

[0047] S5. Assemble the seal onto the cover plate to seal the exposed middle section of the wire.

[0048] The charging pile charging module assembly cable and its preparation method of the present invention have the following advantages over the prior art:

[0049] By setting a substrate for integrating the ends of the wires and sealing the wires with a cover plate and sealant, the integration of the wires is achieved. This makes the wires more regular, thinner, and more protective, while also having the advantages of small space occupation and easy integration. The ends of the wires are partially exposed, so the lead wires can be directly connected to the wires to achieve connection with electrical components, which improves the convenience of assembly.

[0050] The ends of the wire are left exposed to facilitate soldering to the lead wires, while the middle section of the wire is left completely exposed to facilitate the drawing of wires from the middle section for connection to other electrical components. The middle section of the wire is then sealed with a sealing element and a cover plate to ensure good electrical safety performance.

[0051] By setting the first, second, and third electrical terminals, the continuity of the wire can be controlled, and the line can be led out from the end and middle of the wire. This effectively expands the circuit connection location and improves the convenience of connecting the assembled cable with electrical components.

[0052] By setting an expansion section on the substrate, the spacing between multiple wires can be effectively increased, and the volume of the substrate can be controlled as much as possible. This makes it easy to integrate the first electrical terminal directly into the substrate. The first electrical terminal relies on the rotation of the cam to move the slider in conjunction with the dial plate, thereby making contact with the wire and controlling the connection between the external wiring and the wire to realize the circuit on and off. This helps to reduce the number of circuit switches used, thus making the integration of the circuit in the charging pile more convenient.

[0053] In the second electrical terminal, the conductive rod is pressed onto the wire by the action of the elastic ring, which makes it easy to lead the circuit out from any position of the corresponding substrate of the wire; in the sealing structure used to seal the middle section of the wire, the bottom plate is provided with a cuttable part, and the cover plate connected to the bottom plate is easy to disassemble. After the cover plate is removed, the part of the bottom plate corresponding to the wire can be cut to facilitate the lead-out of the circuit. Then the cover plate is assembled to seal it, and the limiting groove on the cover plate limits the lead-out wire, which can ensure the stability of the structure.

[0054] By setting the substrate into three parts—plate, insulating film, and wire frame—the wire frame can be used to position the wires, and the insulating film can be easily integrated onto the wire frame. In this way, the insulating film can protect the wires. After the wires are integrated into the plate, the plate can squeeze the two insulating films to cover the wires. After the two insulating films are bonded together, they can fill the gaps and provide insulation, thus ensuring the reliability of the electrical structure application. Attached Figure Description

[0077] like Figures 1-14 As shown, the charging module assembly cable of the charging pile of the present invention includes a substrate 1, a wire 2, a cover plate 3, a seal 4, a lead wire 5, a first power terminal 6, a second power terminal 7, and a third power terminal.

[0078] like Figures 1-9 As shown, at least two substrates 1 are provided; multiple wires 2 are provided, with each end of a portion of the wires 2 integrated into a substrate 1, both ends of the wires 2 having a covering layer, the ends of the wires 2 being partially exposed, and the middle section of the wires 2 being completely exposed; a cover plate 3 is provided on the substrate 1, and the cover plate 3 covers the unexposed portions of the ends of the wires 2 and the middle section of the wires 2, the cover plate 3 fastens to the middle section of the wires 2, and a first slot 301 is provided corresponding to the gap between adjacent wires 2; a sealing member 4 is inserted into the first slot 301, and the sealing member 4 cooperates with the cover plate 3 to seal the middle section of the wires 2; a lead wire 5 is connected to the exposed portion at the end of the wires 2;

[0079] As described above, there are two substrates 1 and several wires 2, which are divided into two parts. One part of the wires is connected to one substrate 1 at each end. Specifically, based on the radial midline of the wire 2, half of the wire 2 is integrated into the substrate 1, while the other half is exposed, forming a partially exposed structure.

[0080] Furthermore, the portion of the wire 2 integrated with the substrate 1 is provided with an outer cladding layer. Specifically, the outer cladding layer is formed at the end of the wire 2 by extrusion. The outer cladding layer is integrated onto the wire 2 at intervals. Then, the wire 2 is cut off from the location where the outer cladding layer is provided to form a wire 2 with outer cladding layers at both ends.

[0081] The portion of wire 2 with an outer sheath at its end is integrated into substrate 1, while the middle portion of wire 2 does not have an outer sheath and has an exposed core structure; specifically, the core is a conductor.

[0082] The cover plate 3 is connected to the substrate 1 to cover the part of the wire 2 that is not integrated into the substrate 1. The cover plate 3 also has a local area corresponding to the middle section of the wire 2. This part of the cover plate 3 is provided with a first slot 301. The sealing member 4 is inserted into the first slot 301 to cooperate with the cover plate 3 to seal the exposed middle section of the wire 2, and at the same time realize the limiting and division of multiple wires 2.

[0083] Furthermore, the outer sheath of the end of the wire 2 is removed to expose the wire core. At the same time, the cover plate 3 is slotted corresponding to the exposed part of the wire core to facilitate the connection of the lead wire 5, and then the electrical components can be connected through the lead wire 5.

[0084] This structure integrates the wire 2 by using a base plate 1 to integrate the end of the wire 2 and sealing the wire 2 with a cover plate 3 and a sealing element 4. This achieves the integration of the wire 2, making the wire 2 more regular and presenting an overall plate-like structure. It does not require wiring; it can be installed as a whole into the charging pile, and then the lead wire 5 can be connected to the electrical components. It has the advantages of small space occupation and easy integration. At the same time, the wire is not easy to break inside. Even if a fault occurs, the failure point will only be concentrated at the connection between the lead wire 5 and the wire 2, which improves the convenience of assembly and maintenance.

[0085] A portion of the wire 2 is exposed, while the middle section of the wire 2 is completely exposed. This makes it easy to draw wires from the middle section of the wire 2 and connect them to other electrical components. Then, the middle section of the wire 2 can be sealed with the sealing element 4 and the cover plate 3 to ensure good electrical safety performance.

[0086] like Figure 8 As shown, the cover plate 3 includes a first section 31, a second section 32, and a third section 33. The first section 31 and the second section 32 are each provided with a substrate 1. The first section 31 and the second section 32 cooperate with the substrate 1 to seal both ends of the wire 2, and the first section 31 and the second section 32 are provided with slots 302 on the exposed ends of the wire 2. The third section 33 corresponds to the middle section of the wire 2, and a first slot 301 is formed on the third section 33.

[0087] As described above, in the cover plate 3, the first segment 31 and the second segment 32 are each integrated with a substrate 1 to seal the portion of the wire 2 with an outer sheath. Simultaneously, the first segment 31 and the second segment 32 are provided with first slots 301, thus facilitating the soldering of the end of the lead wire 5 to the exposed area of ​​the wire core at the end of the wire 2 after the cover plate 3 is integrated with the substrate 1.

[0088] The third segment 33 is designed for the exposed area in the middle section of the wire 2, and a first slot 301 is provided. In this way, the third segment 33 can be made for the exposed area in the middle section of the wire 2, and the sealing member 4 is inserted and fixed through the first slot 301 to seal the middle section of the wire 2. In this way, the integration convenience of this assembled cable and the electrical safety of its application can be effectively ensured.

[0089] like Figure 7 , Figure 8 and Figure 12 As shown, the sealing element 4 includes a base plate 41 and a cover plate 42. The base plate 41 corresponds to the middle section and the third section 33 of the wire 2. The base plate 41 holds the wire 2, and the base plate 41 is provided with a second slot 401 corresponding to the gap between adjacent wires 2. The cover plate 42 is fastened to the cover plate 3. A part of the cover plate 42 protrudes and presses the lead wire 5. The part of the cover plate 42 protrudes and is inserted into the first slot 301 and the second slot 401.

[0090] As described above, the sealing element 4 is configured in two parts, wherein the bottom plate 41 is configured to correspond to the third section 33 of the cover plate 3, so that the middle section of the wire 2 can be clamped and fixed. Furthermore, the bottom plate 41 is provided with a buckle to fix the middle sections of multiple wires 2 at intervals. At the same time, the bottom plate 41 is provided with a second slot 401, which corresponds to the first slot 301.

[0091] Among them, the cover plate 42 is fastened to the cover plate 3, and a part of the cover plate 42 passes through the first slot 301 on the third section 33 and through the second slot 401 on the bottom plate 41. In this way, the exposed area in the middle section of the wire 2 is completely sealed to ensure good electrical insulation performance.

[0092] The cover plate 42 has a partial protrusion for embedding into the slot 302, so that it can hold the lead wire 5 so that the solder joint between the lead wire 5 and the end of the wire 2 will not fail when the lead wire 5 is under force, thereby facilitating the connection of the lead wire 5 to electrical components.

[0093] Specifically, both the cover plate 3 and the cover plate 42 are equipped with fixing structures. Specifically, the cover plate 3 and the cover plate 42 are equipped with brackets or threaded rods to facilitate connection and fixing with the charging pile body through fasteners or nuts; specifically, they are connected and fixed with the electrical cabinet of the charging pile.

[0094] like Figures 1-11 As shown, the first power terminal 6 is integrated at the end of the substrate 1 and the cover plate 3, and is used to control the on / off state of part of the wire 2; the second power terminal 7 is integrated on the cover plate 3 and the sealing member 4, and is used for the passage leading out of the end of part of the wire 2; the third power terminal is set at the middle section of the wire 2, and is used for the passage leading out of the middle section of part of the wire 2.

[0095] As described above, this assembly cable adopts an integrated structure, which not only occupies little space and is easy to assemble, but also provides multiple terminals for connecting wires in order to facilitate the lead-out of wires to adapt to different layouts of electrical components.

[0096] The first electrical terminal 6 is integrated on the substrate 1 and the cover plate 3, which is used for the lead-out of the wire and for the on / off control of the wire 2.

[0097] The third electrical terminal 7 is integrated on the cover plate 3 and the sealing member 4, so as to facilitate the lead-out of wires from any position of the joint between the wire 2 and the substrate 1, so as to facilitate the connection of electrical components.

[0098] The third power terminal is located in the middle section of wire 2, which is exposed to facilitate the lead-out of the wire core, thus making its application more convenient.

[0099] like Figures 9-11 As shown, the end of the substrate 1 is provided with an expanded diameter section 101. The first power terminal 6 includes a top block 61, a slider 62, a spring 63, a dial plate 64, an external wire 65, and a cam 66. Among the wires 2, a portion of the wires 2 are integrated into the substrate 1. The wires 2 inside the substrate 1 extend to the expanded diameter section 101, and the spacing between the wires 2 within the expanded diameter section 101 increases. The top block 61 and the slider 62 are slidably disposed within the substrate 1, with the slider 62 close to the end of the wire 2 relative to the top block 61. One end of the spring 63 abuts against the top block 61, and the other end abuts against the slider 62. The dial plate 64 is connected to the slider 62 and passes through the substrate 1. One end of the external wire 65 is inserted into the substrate 1, and the end of the external wire 65 abuts against the top block 61. The cam 66 is rotatably disposed on the substrate 1, and the cam 66 corresponds to the dial plate 64.

[0100] As described above, this assembled cable has several wires, some of which are laid out using the aforementioned structure, while some wires 2 are only integrated within the substrate 1, with one end penetrating the substrate 1 and the other end located within the substrate 1. The first electrical terminal 6 is integrated at the end of the substrate 1 to realize the on / off control of this part of the wire; of course, the integrated structure of the first electrical terminal 6 can also be applied to the above-described cable structure.

[0101] The end of the substrate 1 is provided with an expansion structure, so that the portion of the wire 2 located within the expansion section 101 can be provided with a larger interval, so as to facilitate the laying of the first power terminal 6, while not causing the volume of the assembled cable to increase excessively.

[0102] Specifically, at one end of the corresponding wire 2 located within the substrate 1, a top block 61, a slider 62, a spring 63, a toggle plate 64, an external wire 65, and a cam 66 are provided. Under the action of the spring 63, the slider 62 will abut against the end of the wire 2, while the top block 61 will abut against the external wire 65. In this way, a passage is formed between the external wire 65 and the wire 2. When the slider 62 moves, it compresses the spring 63, so the slider 62 does not contact the end of the wire 2, thereby forming an open circuit and realizing switch control.

[0103] Specifically, the movement of slider 62 is controlled by dial plate 64 and cam 66. When adjustment is required, cam 66 is rotated, and cam 66 can push dial plate 64 with its protruding part, thereby moving slider 62 through dial plate 64. It has the advantage of convenient operation.

[0104] Furthermore, a locking pin can be provided on the cam 66 to prevent free rotation that could lead to an inability to control the circuit's on / off state.

[0105] like Figure 3 , Figure 6 and Figure 14 As shown, the second electrical terminal 7 includes a conductive rod 71 and an elastic ring 72. The conductive rod 71 has a stepped structure. The large-diameter section of the conductive rod 71 abuts against the wire 2, and the small-diameter section of the conductive rod 71 passes through the cover plate 3 and the sealing element 4. The elastic ring 72 is sleeved on the small-diameter section of the conductive rod 71. One end of the elastic ring 72 abuts against the large-diameter section of the conductive rod 71, and the other end of the elastic ring 72 abuts against the cover plate 3.

[0106] As described above, the second electrical terminal 7 is used for radial lead-out of the end of the wire 2. Specifically, a stepped hole is opened on the cover plate 3, with the small diameter end of the stepped hole away from the wire 2. Then, an elastic ring 72 is installed into the large diameter end of the stepped hole, and a conductive rod 71 is inserted and installed. In this way, the small diameter section of the conductive rod 71 can directly pass through the cover plate 3 and the sealing member 4, while the large diameter section of the conductive rod 71 is stably held against the wire 2 under the action of the elastic ring 72, thereby realizing the lead-out of the circuit.

[0107] Specifically, in this structure, the cover plate 3 and the substrate 1 are detachably connected to facilitate the assembly of the second power terminal 7. In other cases, the cover plate 3 can be injection molded into the substrate 1, and the changes can be made according to the assembly requirements.

[0108] Specifically, the part that needs to be set as the second electrical terminal 7 requires the outer sheath of the corresponding wire 2 to be removed so that it can make contact with the conductive rod 71;

[0109] Specifically, the conductive rod 71 is configured as a threaded rod to facilitate the connection of an insulating threaded cap.

[0110] like Figures 8-12As shown, the portion of the base plate 41 corresponding to the middle section of the wire 2 is a cuttable structure, which can be cut to form a notch so that the middle section of the wire 2 can be connected to the external wiring and lead out to form a third electrical terminal; the portion of the cover plate 42 that protrudes and is inserted into the first slot 301 and the second slot 401 is provided with a limiting groove 402, which is used to limit the external wiring of the middle section of the wire 2.

[0111] As described above, the formation of the third electrical terminal depends on the exposed middle section of wire 2;

[0112] The portion of the base plate 41 corresponding to the middle section of wire 2 is designed to be cutable, allowing for the creation of notches to connect external wires.

[0113] Specifically, a snap-fit ​​bracket is provided on the base plate 41, and the middle section of the base plate 41 corresponding to the wire 2 is set as a strip structure. The snap-fit ​​bracket connects several strip structures corresponding to the wire 2. In this way, the strip structure will not fall off after the base plate 41 is cut, and the snap-fit ​​bracket can fix and limit the wire 2.

[0114] Furthermore, the cover plate 42 has a limiting groove in the part that passes through the first slot 301 and the second slot 401 to limit the lead-out wire, and works with the electrical cabinet plate of the charging pile to clamp and fix the cable to ensure the stability of the connection point between the wire and the middle section of the cable 2.

[0115] like Figures 9-13 As shown, the substrate 1 includes a plate 11 and a separator 12. There are two plates 11, and wire grooves 102 are provided on the opposite surfaces of the two plates 11. Part of the wire 2 is clamped in the wire grooves 102. One separator 12 is provided on each of the opposite surfaces of the two plates 11. The portion of the separator 12 corresponding to the wire groove 102 is bonded to the wire 2 and the groove wall of the wire groove 102. The portion of the separator 12 corresponding to the spaced interval between adjacent wires 2 is bonded to each other and to the plate 11.

[0116] As described above, the substrate 1 has two plates 11. The substrate 1 is formed by an assembly structure. The plates 11 have grooves 102 to hold the wires 2. At the same time, there are isolation films 12 on both sides of the wires 2. After the two plates 11 are integrated, the two isolation films 12 will come into contact and stick to each other when squeezed, forming a coating layer on the outside of the wires 2, realizing insulation between multiple wires 2, thereby fully ensuring the electrical stability of the application; even if the substrate 1 is cracked, the application safety can be ensured.

[0117] like Figure 13 As shown, the substrate 1 also includes a wire frame 13, and the separator 12 includes a film layer 121 and a retainer 122. The wire frame 13 holds the wires 2 to limit the position of multiple wires 2. One film layer 121 is attached to each side of the wire frame 13. The retainer 122 surrounds the film layer 121.

[0118] As described above, by setting up the wire rack 13, multiple wires 2 can be limited so that the wires 2 can be aligned with the wire groove 102.

[0119] The isolation membrane 12 is divided into two parts: membrane layer 121 and retainer 122. The retainer 122 is located at the edge of membrane layer 121 to form a support frame. Thus, the isolation membrane 12 has a stable structure and can be directly pasted to both sides of the wire frame 13. When assembling the plate 11, the plate 11 can directly contact the isolation membrane 12. By pressing the two isolation membranes 12 with the plate 11, the isolation membranes 12 can be used to cover the wire 2. After the two isolation membranes 12 are bonded together, they can fill the gap and provide insulation to ensure the reliability of the electrical structure application.
