[0002] It should be noted that at present, a photovoltaic module (such as a solar cell) is a semiconductor wafer that generates electricity through a photovoltaic effect. The photovoltaic module is usually connected to a power supply device through a lead bundle. Meanwhile, the photovoltaic module has realized pipeline automatic production. In the production, different processes are transferred through an automatic chain or other transfer devices, and corresponding function detection is completed during the transfer to ensure the production quality of the photovoltaic module.

[0003] Among them, when the photovoltaic module is subjected to function detection, such as IV (current-voltage) electrical performance testing, EL electroluminescence testing, insulation voltage testing and other related tests, the lead bundle of the photovoltaic module needs to be electrically connected to the testing device.

[0004] In the related art, when the photovoltaic module is subjected to related testing, an operator needs to manually electrically connect the lead bundle of the photovoltaic module to the cable of the testing device to meet subsequent production actions.

The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0033] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application. Figures 1-5 The electric connector 100 for the photovoltaic module 200 according to the embodiments of the present application is described below, which is used for electrically connecting with the photovoltaic module 200 when the performance test of the photovoltaic module is needed, and the switching between the photovoltaic module 200 and the test equipment can be realized through the electric connector 100. Wherein, the photovoltaic module 200 has the connecting cable 210, and the electric connector 100 can be electrically connected with the connecting cable 210 led out from the photovoltaic module 200.

[0034] The electric connector 100 according to the embodiments of the present application comprises: a connector body 1, a first electric connecting part 2 and a second electric connecting part 3.

[0035] Wherein, the connector body 1 is provided with a fixing part 5, the fixing part 5 is arranged on the connector body 1, and the fixing part 5 is used for detachably connecting and fixing with the photovoltaic module 200, so as to fix the connector body 1 with the photovoltaic module 200 through the fixing part 5, thereby facilitating the electric connection between the connector body 1 and the connecting cable 210 or the test equipment.

[0036] Referring to Figure 1As shown, the first electrical connection part 2 is connected to the connector body 1, and the first electrical connection part 2 is used for electrical connection with the connection cable 210, the second electrical connection part 3 is arranged on the first wall surface 11 of the connector body 1 away from the photovoltaic module 200, the second electrical connection part 3 is electrically connected with the first electrical connection part 2, and the second electrical connection part 3 is used for electrical connection with the test equipment, so that the electrical connection between the test equipment and the photovoltaic module 200 is realized through the electrical connector 100, and the wiring difficulty of the photovoltaic module 200 in the test is reduced.

[0037] It can be understood that when the photovoltaic module 200 needs to be functionally detected, the connector body 1 is fixed on the photovoltaic module 200 before the photovoltaic module 200 is placed on the conveying mechanism, and the first connection part is electrically connected with the connection cable, so that the connection between the electrical connector 100 and the photovoltaic module 200 is realized, so that the connection cable can be constrained to prevent accidental damage during transmission, and the positive and negative poles of the photovoltaic module can also be connected, and the test difficulty of the photovoltaic module 200 is reduced, and the test convenience is improved.

[0038] Among them, the cooperation mode of the electrical connector 100 and the photovoltaic module 200 in the application is simple, the installation position can be adjusted according to the arrangement requirement of the test equipment, and the compatibility is high.

[0039] It should be noted that at present, the photovoltaic module (such as a solar cell) is a semiconductor piece that generates electricity through the photovoltaic effect, and the photovoltaic module is usually connected with the power supply equipment through the lead-out cable. At the same time, the photovoltaic module has realized the automatic production of the assembly line, and the flow of different processes is realized through the automatic chain or other transfer devices in the production, and the corresponding functional detection is completed during the flow to ensure the production quality of the photovoltaic module.

[0040] Among them, when the photovoltaic module is functionally detected, such as IV (current-voltage) electrical performance test, EL electroluminescence test, insulation voltage test and other related tests, the lead-out cable of the photovoltaic module needs to be electrically connected with the test equipment, and the electrical connector 100 needs to follow the photovoltaic module to flow to the test equipment for corresponding functional detection.

[0041] In the related art, when the photovoltaic module is tested, the operator needs to manually electrically connect the lead-out cable of the photovoltaic module with the cable of the test equipment to meet the subsequent production action. Therefore, before and after the test, the cable cannot be effectively fixed during the flow of the photovoltaic module, which is easy to interfere with other mechanisms on the assembly line and cause damage to the test equipment or the photovoltaic module, and it is also inconvenient to connect and disconnect the lead-out cable of the photovoltaic module with the test equipment, and it is difficult to realize automatic plugging, resulting in low overall test efficiency.

[0042] In the present application, the connecting cable 210 of the photovoltaic module 200 can be connected and matched with the first electrical connection part 2, and the connector body 1 is further fixedly arranged on the photovoltaic module 200 to be electrically connected with the photovoltaic module 200 through the electrical connector 100 and to play a restraining effect on the connecting cable 210, so as to effectively prevent the connecting cable 210 from interfering with other equipment on the production line, avoid damaging the photovoltaic module 200 in the process of circulation, and enable the test equipment to be connected and matched with the second electrical connection part 3 arranged on the first wall surface 11 to realize the quick contact and conduction of the test probe of the test equipment with the positive and negative poles of the photovoltaic module, so as to save the manual connection and disconnection of the connecting cable harness and the test probe of the test equipment during testing, thereby improving the convenience and testing efficiency.

[0043] As shown in Figure 1 and Figure 3 In some embodiments of the present application, the first electrical connection part 2 includes a first connecting cable harness 21 and a second connecting cable harness 22.

[0044] The first connecting cable harness 21 is led out from one side of the connector body 1 in the circumferential direction, and the first connecting cable harness 21 is used to be electrically connected with the first connecting end 211 in the connecting cable 210; the second connecting cable harness 22 is led out from one side of the connector body 1 in the circumferential direction, and the second connecting cable harness 22 is used to be electrically connected with the second connecting end 212 in the connecting cable 210. In this way, the electrical connector 100 is electrically connected with the connecting cable 210 in the photovoltaic module 200.

[0045] It can be understood that the photovoltaic module 200 is provided with a wiring structure (such as a junction box), the connecting cable 210 can be led out from the wiring structure, and the first connecting end 211 and the second connecting end 212 in the connecting cable 210 are one positive end and the other negative end, and the wiring structure is usually arranged on one side surface in the thickness direction of the photovoltaic module 200.

[0046] During the connection and matching of the electrical connector 100 and the photovoltaic module 200, the connector body 1 can be arranged on the side surface of the photovoltaic module 200 provided with the wiring structure, so as to facilitate the connection and matching of the first connecting cable harness 21 and the second connecting cable harness 22 with the connecting cable 210. At the same time, the first connecting cable harness 21 and the second connecting cable harness 22 led out from the side wall 13 of the connector body 1 can extend to the side of the wiring structure, so as to arrange the first connecting cable harness 21 and the second connecting cable harness 22 at a position suitable for being connected with the connecting cable 210, which helps to shorten the arrangement length of the first connecting cable harness 21 and the second connecting cable harness 22, and can prevent the first connecting cable harness 21 or the second connecting cable harness 22 from being bent too much.

[0047] In combination with Figure 1 and Figure 3As shown in the further embodiments of the present application, the first connecting wire harness 21 and the second connecting wire harness 22 are led out from the side wall 13 on the same side of the connector body 1, so as to facilitate the connection and cooperation of the electrical connector 100 with the connecting cable 210 in the photovoltaic module 200.

[0048] In combination Figure 1 And Figure 3 As shown, the first connecting wire harness 21 and the second connecting wire harness 22 are led out from the side wall 13 on the same side of the connector body. When the electrical connector 100 needs to be connected and cooperated with the photovoltaic module 200, the connector body 1 can be arranged on one side of the wiring structure, and the side wall 13 of the connector body 1 leading out the first connecting wire harness 21 and the second connecting wire harness 22 is arranged corresponding to the wiring structure, so as to facilitate the arrangement of the first connecting wire harness 21 and the second connecting wire harness 22 to one side of the wiring structure, and help to shorten the arrangement length of the first connecting wire harness 21 and the second connecting wire harness 22.

[0049] It should be noted that the leading-out mode of the first connecting wire harness 21 and the second connecting wire harness 22 on the connector body 1 can be adaptively adjusted based on the arrangement form of the wiring structure on the photovoltaic module 200, so as to facilitate the corresponding arrangement of the first electrical connection part 2 and the wiring structure, and reduce the wiring difficulty of the electrical connector 100 and the connecting cable 210.

[0050] As Figure 3 And Figure 4 As shown in some embodiments of the present application, the second electrical connection part 3 includes: a first conductive block 31 and a second conductive block 32, the first conductive block 31 is arranged on the first wall surface 11 on the side of the connector body 1 away from the photovoltaic module 200, and the first conductive block 31 is electrically connected with the first connecting wire harness 21; the second conductive block 32 is also arranged on the first wall surface 11, and the second conductive block 32 is electrically connected with the second connecting wire harness 22. Thus, the test equipment can be electrically connected with the first connecting end 211 and the second connecting end 212 of the photovoltaic module 200 by connecting and cooperating with the first conductive block 31 and the second conductive block 32 respectively.

[0051] Among them, the test equipment is electrically connected with the first connecting end 211 by connecting and cooperating with the first conductive block 31, and the test equipment is electrically connected with the second connecting end 212 by connecting and cooperating with the second conductive block 32.

[0052] It can be understood that since the second electrical connection part 3 is configured as a conductive block structure, the test equipment can be electrically connected with the second electrical connection part 3 by abutting, lapping and other cooperation modes, the connection mode is simple, and the electrical connector 100 has good adaptability, which can reduce the cooperation difficulty of the electrical connector 100 and the test equipment.

[0053] As Figure 4As shown, in some embodiments of this application, the connector body 1 has a first receiving groove 101 and a second receiving groove 102 that are open to the side away from the photovoltaic module 200 and are arranged at intervals on the first wall surface 11. The first conductive block 31 is arranged in the first receiving groove 101 and the second conductive block 32 is arranged in the second receiving groove 102.

[0054] Therefore, by accommodating the conductive blocks through the receiving groove structure (i.e., the first receiving groove 101 and the second receiving groove 102 mentioned above), the sidewall 13 of the receiving groove structure can constrain and position the conductive blocks, thereby improving the reliability of the mating between the conductive blocks and the connector body 1. Specifically, the first conductive block 31 can be exposed through the open end of the first receiving groove 101, and the second conductive block 32 can be exposed through the open end of the second receiving groove 102, thus facilitating the connection and mating of the testing equipment with the first conductive block 31 and the second conductive block 32 respectively.

[0055] Furthermore, both the first conductive block 31 and the second conductive block 32 are exposed at the first wall surface 11, and also exposed from the side of the connector body 1 away from the connector body 1, so as to avoid the photovoltaic module 200 when the test equipment is connected and engaged with the first conductive block 31 and the second conductive block 32, and avoid interference between the test equipment and the photovoltaic module 200.

[0056] like Figure 4 As shown, in some embodiments of this application, the electrical connector 100 further includes a first elastic member 41 and a second elastic member 42. The first elastic member 41 is disposed in the first receiving groove 101 and is elastically supported between the first conductive block 31 and the bottom wall of the first receiving groove 101, and at least a portion of the first conductive block 31 protrudes from the first wall surface 11 along the support direction. The second elastic member 42 is disposed in the second receiving groove 102 and is elastically supported between the second conductive block 32 and the bottom wall of the second receiving groove 102, and at least a portion of the second conductive block 32 protrudes from the first wall surface 11 along the support direction.

[0057] The bottom wall of the receiving groove (i.e., the first receiving groove 101 and the second receiving groove 102 mentioned above) refers to the side wall of the receiving groove opposite to the open end. When the first elastic member 41 is elastically supported between the first conductive block 31 and the bottom wall of the first receiving groove 101, the first conductive block 31 tends to extend out of the receiving groove under the support of the first elastic member 41, so as to ensure the connection and cooperation effect between the first conductive block 31 and the test equipment; when the second elastic member 42 is elastically supported between the second conductive block 32 and the bottom wall of the second receiving groove 102, the second conductive block 32 tends to extend out of the receiving groove under the support of the second elastic member 42, so as to ensure the connection and cooperation effect between the second conductive block 32 and the test equipment.

[0058] It can be understood that the elastic members (i.e., the first elastic member 41 and the second elastic member 42 described above) can be used to achieve a small elastic displacement of the conductive block at the accommodating groove, avoid the hard contact between the electrical connection structure (such as a probe, etc.) of the detection device and the conductive block, and reduce the risk of damage to the electrical connection structure of the detection device and the conductive block.

[0059] As shown in the drawings, Figure 5 In some embodiments of the present application, the fixing part 5 is configured as a suction cup 51, which is arranged on the second wall surface 12 opposite to the connector body 1 and the photovoltaic module 200, and the suction cup 51 is used to be adsorbed and fixed with the surface of the photovoltaic module 200.

[0060] It can be understood that the suction cup 51 can be adsorbed and fixed on the photovoltaic module 200 by evacuating the air between the suction cup 51 and the cooperating surface on the photovoltaic module 200, thereby achieving the fixed connection between the connector body 1 and the photovoltaic module 200, so that the electrical connector 100 can be transported synchronously with the photovoltaic module 200, so as to be electrically connected and cooperated with the detection equipment on the production line through the electrical connector 100, and the electrical connection mode between the test equipment and the electrical connector 100 is simple, thereby facilitating the automatic testing.

[0061] In further embodiments of the present application, the number of suction cups 51 is multiple, so as to improve the fixed cooperation effect between the fixing part and the photovoltaic module 200, and improve the stability of the connector body 1 arranged on the photovoltaic module 200.

[0062] As shown in the drawings, Figure 2 In some embodiments of the present application, the fixing part 5 includes a first magnetic attraction member 521 and a second magnetic attraction member 522, the first magnetic attraction member 521 is arranged on the second wall surface 12 opposite to the connector body 1 and the photovoltaic module 200, and the second magnetic attraction member 522 is arranged on the side of the photovoltaic module 200 away from the connector body 1, and the second magnetic attraction member 522 is used to be magnetically attracted and cooperated with the first magnetic attraction member 521 to clamp the photovoltaic module 200 between the first magnetic attraction member 521 and the second magnetic attraction member 522, thereby magnetically fixing the connector body 1 and the photovoltaic module 200.

[0063] It should be noted that the photovoltaic module 200 is a semiconductor sheet, i.e., the photovoltaic module 200 cannot be magnetically attracted and cooperated with the magnetic attraction member, so that the first magnetic attraction member 521 and the second magnetic attraction member 522 are arranged on the two sides of the photovoltaic module 200 respectively, and are adsorbed and cooperated by the first magnetic attraction member 521 and the second magnetic attraction member 522, so that the photovoltaic module 200 is clamped and arranged between the first magnetic attraction member 521 and the second magnetic attraction member 522, thereby achieving the connection and fixation of the connector body 1 and the photovoltaic module 200.

[0064] At least one of the first magnetic attraction member 521 and the second magnetic attraction member 522 is configured as a magnet. When only one of the first magnetic attraction member 521 and the second magnetic attraction member 522 is configured as a magnet, the other one of the first magnetic attraction member 521 and the second magnetic attraction member 522 is configured as a metal member (for example, a component made of iron, cobalt, nickel, etc.) suitable for being attracted to the magnet. Thus, when the first magnetic attraction member 521 and the second magnetic attraction member 522 are magnetically attracted to each other, the first magnetic attraction member 521 and the second magnetic attraction member 522 have a tendency to move closer to each other, so that the photovoltaic module 200 can be clamped by the first magnetic attraction member 521 and the second magnetic attraction member 522, and the connection between the connector body 1 and the photovoltaic module 200 is simple and convenient to operate, and the fixed position of the connector body 1 relative to the photovoltaic module 200 is easy to adjust.

[0065] As shown in Figure 2 In further embodiments of the present application, the second wall surface 12 of the connector body 1 is formed with a mounting groove 103 open to the side of the photovoltaic module 200, the first magnetic attraction member 521 is arranged in the mounting groove 103, and the first magnetic attraction member 521 is arranged on the side surface of the photovoltaic module 200 opposite to the second wall surface 12, so that the first magnetic attraction member 521 can be accommodated in the mounting groove 103, and the first magnetic attraction member 521 can be arranged in the position magnetically attracted to the second magnetic attraction member 522, so as to avoid excessive local pressure on the photovoltaic module 200 when the first magnetic attraction member 521 and the second magnetic attraction member 522 are magnetically attracted to each other, and improve the reliability of the connection between the electrical connector 100 and the photovoltaic module 200.

[0066] It should be noted that the connection between the first magnetic attraction member 521 and the connector body 1 is not limited to this, and the first magnetic attraction member 521 can be fixed to the connector body 1 by adhesion, screwing (for example, screwing), etc.

[0067] Referring to Figure 2 It can be understood that the second magnetic attraction member 522 is provided with a housing 53, and the housing 53 covers the second magnetic attraction member 522, so that the operator can drive the housing 53 to move the second magnetic attraction member 522, improving the operation convenience.

[0068] The electrical connector 100 according to the embodiments of the present application has at least the following advantages compared with the prior art:

[0069] (1) The electrical connector 100 can be fixedly arranged on the photovoltaic module 200 through the fixing part 5, so that the electrical connector 100 can flow synchronously with the photovoltaic module 200 on the production line, and can be electrically connected to the testing equipment through the second electrical connection part 3 of the electrical connector 100 to meet the testing requirements of the photovoltaic module 200. In addition, the arrangement position of the electrical connector 100 relative to the photovoltaic module 200 is adjustable, which can improve the convenience and compatibility of the photovoltaic module 200 testing process. At the same time, it can play a good restraining role on the connecting cable 210 of the photovoltaic module 200, avoiding interference between the connecting cable 210 and other equipment.

[0070] (2) The second electrical connection part 3 is constructed as an electrical connection block with a certain range of elastic displacement. It can achieve electrical connection with the test equipment by abutting and mating. The connection method is simple and highly reliable. No plugging and unplugging operation is required, which reduces the difficulty of docking between the electrical connector 100 and the test equipment.

[0071] (3) The first electrical connection part 2 and the second electrical connection part 3 in this application serve as circuit bridges. The electrical connector 100 constrains the connecting cable 210 in the photovoltaic module 200. The first conductive block 31 and the second conductive block 32 are exposed, which is beneficial for the first conductive block 31 and the second conductive block 32 to be electrically connected and cooperated with the test equipment respectively, thereby improving the continuity of testing and work efficiency.

[0072] It should be noted that the fixed position of the electrical connector 100 on the photovoltaic module 200 can be adaptively adjusted according to the tooling position of the test equipment by manual adjustment or tooling push adjustment, which can meet a variety of test requirements and realize automated operation.

[0073] Similarly, a machine vision positioning device can be added to the testing equipment to detect the position of the second electrical connection part 2 and adaptively adjust the position of the transmission mechanism or the probe on the testing equipment to match the second electrical connection part 2.

[0074] The testing system for photovoltaic module 200 according to the embodiments of this application includes the electrical connector 100 described above. The testing system has the same advantages as the prior art and the electrical connector 100 described above, and will not be described again here.

[0075] The testing equipment includes a lifting module and probes mounted on the lifting module. The two probes are electrically connected to the positive and negative terminals of the testing equipment, respectively. The probes are moved up and down by the lifting module to make an 8-contact electrical connection with the second electrical connection part 2, so as to facilitate rapid testing of photovoltaic modules.
