Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, and in particular to a fuel cell bipolar plate inspection wiring structure. The utility model also relates to a fuel cell bipolar plate inspection device having the fuel cell bipolar plate inspection wiring structure. Background Art

[0002] A fuel cell stack is the main component of a hydrogen energy device's power unit. Bipolar plates and membrane electrodes form the basic power generation unit, or single cell. A fuel cell stack is constructed by stacking multiple fuel cell units in series. Bipolar plates and membrane electrodes are alternately stacked, with seals embedded between the units. After being compressed by front and rear end plates and secured with screws, the fuel cell stack is formed.

[0003] Fuel cells, consisting of a set of bipolar plates and membrane electrode systems, have low output voltage and current density. To achieve high voltage and power, multiple cells are typically connected in series to form a stack. The bipolar plates connect the cells in series, provide gas flow paths within the cells, and collect and conduct current. This stack structure is the core of the fuel cell system and a key fuel cell technology.

[0004] During fuel cell stack testing, a pin inspection method is typically used to check the status of individual cells in this stack structure. However, most pins in traditional structures have poor contact with the bipolar plates during testing, which can easily lead to sudden stops in testing, loosening or breaking of the pins, and causing a short circuit between adjacent bipolar plates, resulting in serious consequences such as stack burns. While some pin structures can improve contact with the bipolar plates, they are easy to insert but difficult to remove, making them unsuitable for repeated insertion and removal. Utility Model Content

[0005] In view of this, the present invention aims to provide a fuel cell bipolar plate inspection wiring structure to improve the contact firmness with the bipolar plate and facilitate removal for repeated use.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A fuel cell bipolar plate inspection wiring structure includes a connecting portion and a pin portion connected to each other;

[0008] The connecting portion is used to connect to the wiring harness, and the pin portion includes a main body connected to the connecting portion, and buckles made of elastic material provided on two opposite sides of the main body;

[0009] The buckles on each side can be clamped in the clamping grooves of the bipolar plates on the corresponding sides, and a gap is formed between the buckles on each side and the main body, and the gap is used to provide space for the buckles to deform toward one side of the main body.

[0010] Furthermore, the buckle includes a main body portion connected to the main body, a clamping portion connected to the main body portion and bent toward the main body, and a clamping portion connected to the clamping portion and

[0011] An extension portion extends along the length direction of the main body, and gaps are formed between the extension portion, the clamping portion, the main body portion, and the main body. The clamping portion can be clamped in the clamping groove of the corresponding side bipolar plate.

[0012] Furthermore, the body portion includes a connecting section connected to the end of the main body, and an abutting section provided at one end of the connecting section;

[0013] The connecting section is arranged at an acute angle with the main body, and the abutting section extends along the length direction of the main body. Furthermore, the extension portion on at least one side is away from one end of the main body portion and bends toward a side away from the main body.

[0014] Furthermore, the connecting portion includes a connecting tube and a sleeve that are spaced apart;

[0015] The wire harness is inserted into the sleeve, and the inner core of the wire harness is inserted into the connecting cylinder. A protrusion protruding inward is provided on the connecting cylinder, and the protrusion can abut against the inner core.

[0016] Furthermore, the sleeve includes an arc-shaped portion connected to the connecting tube, and clamping portions provided on two opposite sides of the arc-shaped portion;

[0017] The arc-shaped portion has a groove for inserting the wire harness, and the clamping portions on both sides can be bent to clamp the wire harness in the groove.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The fuel cell bipolar plate inspection wiring structure described in the present invention can improve the connection reliability between the pin portion and the bipolar plate and prevent the risk of loosening by making the pin portion include clips provided on two opposite sides of the main body. In addition, by forming a gap between the clips on each side and the main body, it is also convenient to drive the clips to deform toward one side of the main body, thereby facilitating the clips to disengage from the slot and facilitating the removal of the wiring structure for repeated use.

[0020] In addition, the buckle includes a main body portion connected to the main body, a clamping portion bent toward the main body, and an extension portion provided at one end of the main body portion. The simple structure facilitates buckle deformation and further facilitates the buckle to be lifted out of the slot. Extending the extension portion along the length of the main body increases the cantilever length of the buckle, further facilitating buckle deformation. The acute angle between the connecting section and the main body facilitates insertion of the buckle into the slot, while extending the abutment section along the length of the main body improves the buckle's structural strength and increases the contact area between the buckle and the bipolar plate, ensuring the stability of the connection between the buckle and the bipolar plate.

[0021] By bending the extension part away from one end of the main body and toward the side away from the main body, not only the overall structural strength of the buckle can be improved, and the clamping firmness between the buckle and the bipolar plate can be improved, but it can also serve as a force point to facilitate the operation of the extension part to drive the buckle to deform toward the side of the main body, which can help the buckle to escape from the slot.

[0022] Furthermore, the connecting portion comprises a connecting tube and a sleeve spaced apart, resulting in a simple structure that enhances the secure connection between the connecting tube and the wiring harness. The sleeve comprises an arcuate portion connected to the connecting tube, and clamping portions disposed on opposite sides of the arcuate portion. The clamping portions are bent to clamp the wiring harness within the groove, facilitating connection between the sleeve and the wiring harness while also providing improved secure connection. Another object of the present invention is to provide a fuel cell bipolar plate inspection device comprising the fuel cell bipolar plate inspection wiring structure described above, and a wiring harness connected to the connecting portion.

[0023] Furthermore, the fuel cell bipolar plate inspection wiring structure is provided in a plurality of intervals, and the wiring harness is provided in a one-to-one correspondence with the fuel cell bipolar plate inspection wiring structure;

[0024] The fuel cell bipolar plate inspection device further includes an insulating structure for connecting the plurality of wiring harnesses together. The insulating structure has jacks corresponding one to one to the plurality of wiring harnesses, and each wiring harness is inserted into the jack.

[0025] Furthermore, the insulating structure includes a first insulating block and a second insulating block, which are inserted together via an inserting portion, and the insertion hole is formed by the first insulating block and the second insulating block.

[0026] Further,

[0027] The insertion portion includes a dovetail groove provided on one of the first insulating block and the second insulating block, and a dovetail block adapted to the dovetail groove and provided on the other of the first insulating block and the second insulating block.

[0028] The fuel cell bipolar plate inspection device described in the present invention, by providing the fuel cell bipolar plate inspection wiring structure as described above, can ensure a good connection firmness with the bipolar plate, and can effectively prevent the pin portion from loosening or breaking and falling onto the core, thereby effectively avoiding contact between two adjacent bipolar plates and causing a short circuit. At the same time, it can also facilitate the pin portion to escape from the slot, allowing the present wiring structure to be reused.

[0029] Furthermore, the provision of an insulating structure connecting multiple wiring harnesses helps ensure that the wiring structure and wiring harnesses are not at risk of breaking during testing, preventing short circuits caused by contact between adjacent connector structures. The insulating structure comprises a first insulating block and a second insulating block, which are connected together by an inserting portion. This simple structure facilitates design and implementation, and also facilitates the connection of multiple wiring harnesses.

[0030] In addition, the insertion part includes a dovetail groove provided on one of the first insulating block and the second insulating block, and a dovetail block adapted to the dovetail groove and provided on the other of the first insulating block and the second insulating block. This structure is simple and easy to assemble, and can also ensure the firmness of the connection between the first insulating block and the second insulating block.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "mounted," "connected," "connect," and "connector" should be interpreted broadly. For example, they can refer to fixed, removable, or partial connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model in light of specific circumstances.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] Because most pins in traditional structures have poor contact with the bipolar plates 4 during testing, this can cause the test to stop suddenly, or the pins can easily become loose or break and fall onto the core, resulting in a short circuit between two adjacent bipolar plates 4, causing serious consequences such as burning the core. Furthermore, while some pin structures can improve the basic contact strength with the bipolar plates 4, they have the disadvantage of being easy to insert but difficult to remove, making them unsuitable for repeated insertion and removal, and therefore, unsuitable for repeated use. Therefore, this embodiment specifically proposes a novel fuel cell bipolar plate inspection wiring structure, comprising a connecting portion 2 and a pin portion 1.

[0050] The connector 2 is used to connect to the wiring harness 3. The pin connector 1 includes a main body 101 connected to the connector 2 and elastic clips 102 provided on opposite sides of the main body 101. Each clip 102 can be inserted into a slot on the corresponding bipolar plate 4, and a gap is formed between each clip 102 and the main body 101 to provide space for the clip 102 to deform toward the main body 101.

[0051] The fuel cell bipolar plate inspection wiring structure of this embodiment improves the reliability of the connection with the bipolar plate 4 and prevents the risk of loosening by providing the pin portion 1 with clips 102 located on opposite sides of the main body 101. Furthermore, gaps are formed between the clips 102 on each side and the main body 101, facilitating the clips 102 to deform toward the main body 101, thereby facilitating their removal from the slots and facilitating the removal of the wiring structure for repeated use.

[0052] Based on the above overall introduction, an exemplary structure of the fuel cell bipolar plate inspection wiring structure of this embodiment is referred to Figures 1 to 4 As shown in , wherein, as a preferred embodiment, the snap fastener of this embodiment includes a main body portion 1021 connected to the main body 101, a snap-fitting portion 1023 connected to the main body portion 1021 and bent toward the main body 101, and an extension portion connected to the snap-fitting portion 1023 and extending along the length direction of the main body 101, and gaps are formed between the extension portion 1022, the snap-fitting portion 1023 and the main body portion 1021 and the main body 101, and the snap-fitting portion 1023 can be clamped in the slot of the corresponding side bipolar plate 4.

[0053] In this embodiment, preferably, the main body 101 is in the shape of an elongated rod, and the buckle 102 is formed by bending the rod. By forming the buckle 102 by bending the rod, the structure is simple, easy to manufacture, and also has good structural strength. At the same time, the rod-shaped structure can also facilitate the deformation of the buckle 102, which can further facilitate the buckle 102 to escape from the slot. Extending the extension portion 1022 along the length of the main body 101 can increase the cantilever length of the buckle 102, further facilitating the deformation of the buckle 102. In addition, by forming a gap between the extension portion 1022 and the main body 101, it is easy to drive the buckle 102 to deform toward the main body 101, thereby facilitating the buckle 102 to escape from the slot.

[0054] Specifically, combined with Figure 1 and Figure 2 As shown in , the main body 1021 includes a connecting section 10211 connected to the end of the main body 101, and an abutting section 10212 provided at one end of the connecting section 10211. To facilitate insertion of the clip 102 into the slot, the connecting section 10211 forms an acute angle with the main body 101. The abutting section 10212 extends along the length of the main body 101 to enhance the structural strength of the clip 102. It also increases the contact area between the clip 101 and the bipolar plate 4, thereby ensuring the stability of the connection between the clip 102 and the bipolar plate 4.

[0055] In addition, as a further embodiment, Figure 1 Also let Figure 2 As shown in FIG, the engaging portion 1023 of the clip 102 that engages the slot is curved and protrudes toward the side away from the extension 1022. This arrangement not only ensures a secure engagement between the clip 102 and the bipolar plate 4, but it should be noted that, in addition to providing the engaging portion 1023 with an arcuate surface, it can also be provided as a flat surface or an inclined surface that slopes away from the extension 1022.

[0056] In addition, as a further embodiment, Figures 1 to 4 As shown in FIG, the ends of the extensions 1022 on both sides, away from the main body 1021, are bent toward the side away from the main body 101. This arrangement not only improves the overall structural strength of the buckle 102 and enhances the secure connection between the buckle 102 and the bipolar plate 4, but also serves as a force point, facilitating the operation of the extensions 1022 to deform the buckle 102 toward the main body 101, thereby facilitating the buckle 102's removal from the slot.

[0057] It should be noted here that, in addition to Figure 2As shown in , one end of the extension portion 1022 on both sides is bent toward the side away from the main body 101. Alternatively, only one end of the extension portion 1022 on one side is bent toward the side away from the main body 101.

[0058] Continue to refer to Figures 1 to 4 As shown in , as a preferred embodiment, the connecting portion 2 of this embodiment includes a connecting tube 201 and a sleeve 202 arranged at intervals. The connecting tube 201 and the sleeve 202 are arranged at intervals along the length direction of the main body 101. The sleeve 202 is for the wiring harness 3 to be inserted, and the connecting tube 201 is for the inner core of the wiring harness 3 to be inserted, and an inwardly protruding protrusion 2011 is provided on the connecting tube 201, and the protrusion 2011 can abut against the inner core to achieve electrical connection. The connecting portion 2 adopts this structure, which is not only simple in structure and easy to process and manufacture, but also can improve the connection firmness between the connecting tube 201 and the wiring harness 3.

[0059] At this time, in order to facilitate the connection between the connecting tube 201 and the wiring harness 3, as a further embodiment, Figure 1 and Figure 4 As shown in the figure, the sleeve includes an arcuate portion connected to the connecting tube 201 and clamping portions 2021 located on opposite sides of the arcuate portion. The arcuate portion has a groove for inserting the wiring harness 3. The clamping portions 2021 on either side can be bent to clamp the wiring harness 3 within the groove. This arrangement facilitates the insertion of the wiring harness 3 into the sleeve 202 and also ensures a stable connection between the sleeve 202 and the wiring harness 3.

[0060] Based on the above overall description, when using the fuel cell bipolar plate inspection wiring structure of this embodiment, the buckle 102 is locked with the slot of the bipolar plate 4, so that the pin part 1 is reliably connected to the bipolar plate 4, which can effectively prevent the pin part 1 from not contacting the bipolar plate 4, resulting in an emergency stop of the test, loosening or breaking and falling onto the core, causing a short circuit between two adjacent bipolar plates 4. During disassembly, based on Figure 4 In the state shown, gently push the pin portion 1 to extend it upward and fix it with your hand. Then, use your other fingers to press the extension portion 1022 toward the side of the main body 101. At this time, driven by the extension portion 1022, the buckle 102 is also compressed and deformed toward the side of the main body 101. Then, pull the buckle 102 downward to smoothly remove it from the slot of the bipolar plate 4, making it easy to remove and reuse.

[0061] Therefore, the fuel cell bipolar plate inspection wiring structure of this embodiment, by adopting the above structure, not only improves the reliability of the connection with the bipolar plate 4 and prevents the risk of loosening, but also forms a gap between the clips 102 on each side and the main body 101, which facilitates the clips 102 to be deformed toward the main body 101, thereby facilitating the clips 102 to be removed from the slots, making it easier to remove the wiring structure for repeated use.

[0062] In addition, this embodiment also relates to a fuel cell bipolar plate inspection device, including the fuel cell bipolar plate inspection wiring structure as described above, and a wiring harness 3 connected to the fuel cell bipolar plate inspection wiring structure.

[0063] Among them, reference Figure 5 As shown in , as a further embodiment, this embodiment comprises a plurality of fuel cell bipolar plate inspection wiring structures arranged at intervals, with wiring harnesses 3 corresponding one to one with the fuel cell bipolar plate inspection wiring structures. Furthermore, this embodiment of the fuel cell bipolar plate inspection device further comprises an insulating structure 5 that connects the plurality of wiring harnesses 3 together. The insulating structure 5 has receptacles corresponding one to one with the plurality of wiring harnesses 3, and each wiring harness 3 is inserted into a receptacle.

[0064] And, as a preferred embodiment, as Figure 5 and Figure 6 As shown in FIG, the insulating structure 5 of this embodiment includes a first insulating block 501 and a second insulating block 502, which are inserted together via an inserting portion. The first insulating block 501 and the second insulating block 502 form a socket. As a specific embodiment, the insulating structure 5 of this embodiment is rectangular to facilitate manufacturing. Specifically, there are five sockets spaced apart along the length of the insulating structure 5.

[0065] Here, it should be noted that the number of jacks is not limited to Figure 5 As shown in , it can be adjusted according to needs. In addition, in addition to having only one first insulating block 501 and one second insulating block 502, when there are more single cells, the insulating structure 5 can also include multiple first insulating blocks 501 and second insulating blocks 502 arranged in a matching manner.

[0066] In addition, as a preferred embodiment, Figure 5 As shown in FIG, the insertion portion of this embodiment includes a dovetail groove 5021 provided on one of the first insulating block 501 and the second insulating block 502, and a dovetail block 5011 adapted to the dovetail groove 5021 and provided on the other of the first insulating block 501 and the second insulating block 502. In addition, the insertion portion of this embodiment inserts the first insulating block 501 and the second insulating block 502 together along the length direction of the wiring harness 3.

[0067] Among them, combined Figures 6 to 8As shown in FIG, dovetail blocks 5011 are provided at both ends of the first insulating block 501 in the longitudinal direction, protruding toward the second insulating block 502. Correspondingly, dovetail grooves 5021 are provided at both ends of the second insulating block 502 for insertion of the dovetail blocks 5011. The insertion portion of this embodiment, utilizing dovetail grooves 5021 and dovetail blocks 5011, has a simple structure, facilitates assembly, and ensures a secure connection between the first insulating block 501 and the second insulating block 502.

[0068] It is understood that, in addition to providing dovetail blocks 5011 at both ends of the first insulating block 501 and dovetail grooves 5021 at both ends of the second insulating block 502, it is also possible to provide the dovetail block 5011 at only one end of the first insulating block 501 and the dovetail groove 5021 at the other end, with the second insulating block 502 being adapted accordingly. In this case, the first and second insulating blocks 501, 502 can be provided with a common configuration, thereby reducing mold development costs.

[0069] The fuel cell bipolar plate inspection device of this embodiment, by providing the fuel cell bipolar plate inspection wiring structure as described above, can ensure a good connection firmness with the bipolar plate 4, and can effectively prevent the pin portion 1 from loosening or breaking and falling onto the core, thereby effectively avoiding short circuits caused by contact between two adjacent bipolar plates 4. At the same time, it can also facilitate the pin portion 1 to escape from the slot, allowing the present wiring structure to be reused.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
