Technical Field
[0001] This invention relates to the field of electrical connection technology, and in particular to an integrated connector module for a photovoltaic inverter. Background Technology
[0002] As a core component of photovoltaic power generation systems, photovoltaic inverters typically need to connect to various electrical components, such as control boards, communication modules, sampling modules, external wiring harness interfaces, and signal conversion modules. As inverters evolve towards modularity, high integration, and high reliability, their internal and external interface structures are becoming increasingly complex. Traditional single-terminal or single-channel connectors can no longer simultaneously meet the comprehensive requirements of multiple electrical connections, compact structure, stable connection, and environmental adaptability. Therefore, integrated connector modules suitable for photovoltaic inverters have significant application value.
[0003] While some existing photovoltaic connectors can achieve basic conductive connections, they still have shortcomings in modular applications. For example, the guiding and positioning structures of some connectors are relatively simple, making alignment errors prone to occur when multiple interfaces are plugged in simultaneously; some connectors rely solely on a single snap-fit for retention, making them susceptible to loosening under vibration or pulling; and some connectors lack a unified structural solution for multi-channel signal integration, standard interface connections, and the layout of additional circuit functions, which is detrimental to improving overall integration. Furthermore, in the application environment of photovoltaic inverters, there are often higher requirements for the sealing performance, connection stability, and ease of maintenance of the interfaces. If the structural design is unreasonable, it can easily affect the reliability of the entire unit's operation. Summary of the Invention

After the first and second connectors are mated, they can not only complete the electrical connection through the insertion part and the insertion slot, but also form a first layer of retention through the first snap-fit and the second snap-fit, and a second layer of locking through the first locking and the second locking, thereby giving the module a high degree of mechanical connection stability and electrical connection reliability. Multiple sets of corresponding contact spring arrays and conductive contact arrays can be set inside both the first and second power-connecting components, and multiple sets of conductive paths can be connected synchronously within the same connector module. This structure is beneficial for integrating multiple signals, multiple communications, or composite function interfaces in photovoltaic inverter applications, improving modularity. The conductive contact array is set on both sides of the insertion part, while the contact spring array is set in two opposite groups, forming a double-sided frictional abutment relationship during power connection. This structure helps to increase contact pressure and contact area within a limited space, making conductive contact more stable and reducing the risk of poor contact due to vibration or assembly tolerances. Through the mating of the connector with the first insertion cavity, and the combination of the insertion positioning groove, insertion positioning rib, positioning hole and positioning post, the direction, depth and final position of the second connector when inserted into the first connector can be clearly defined, thereby improving the alignment accuracy of multiple sets of electrical connection structures.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0030] like Figures 1-8 As shown, this invention provides a photovoltaic inverter integrated connector module, mainly applicable to applications requiring integrated multi-channel signals and electrical connections, such as internal control modules, signal acquisition modules, communication conversion modules, and other applications within photovoltaic inverters. The photovoltaic inverter integrated connector module of this invention includes a first connector 1, a second connector 2, a first power connection component 3, and a second power connection component 4. The first connector 1 can serve as the connector body installed on the inverter housing, control board area, or fixed end of the equipment; the second connector 2 can serve as a module end, wire harness end, or functional interface end that mates with the first connector 1. After mating, both connectors not only establish multiple conductive connections but also form a relatively stable mechanical locking relationship.
[0031] The first connector 1 is provided with a first insertion portion 11. The first insertion portion 11 is provided with a first insertion cavity 111. The first power connection component 3 is disposed inside the first insertion cavity 111. A first snap-fit member 12 and a first locking member 13 are provided on the outer side of the first insertion portion 11.
[0032] The second connector 2 is provided with a second insertion portion 21. The second insertion portion 21 is provided with a plug 211, and the plug 211 is provided with a second insertion cavity 212. The second power connection assembly 4 is disposed in the second insertion cavity 212. A second snap-fit member 22 and a second locking member 23 are provided on the outer side of the second insertion portion 21.
[0033] In this invention, the second connector 2 is inserted with the first connector 1 facing the whole. The plug 211 first enters the first plug cavity 111, and then drives the plug part 411 in the second power connection component 4 into the plug groove 311 in the first power connection component 3, thereby establishing an internal conductive connection. At the same time, in the later stage of insertion, the first snap-fit component 12 and the second snap-fit component 22 form a snap-fit, and the first locking component 13 and the second locking component 23 form a locking connection to complete the mechanical retention.
[0034] The first electrical connection assembly 3 includes a first PCB board 31, a contact spring array 32, and a first socket 33. The first socket 33 is disposed on the first PCB board 31 and is electrically connected to the contact spring array 32 through circuits on the first PCB board 31. The first PCB board 31 is fixed inside the first connector 1 and constitutes the main conductive bearing base inside the first connector 1.
[0035] The first PCB board 31 is provided with a plug-in slot 311, and the contact spring array 32 is disposed in the plug-in slot 311. That is to say, the first PCB board 31 is not only a planar circuit board for mounting the first socket 33, but also has a plug-in slot 311 structure formed at its front end or middle for the second PCB board 41 to be plugged in, so that the first PCB board 31 simultaneously has the functions of electrical transfer and plug-in bearing.
[0036] A fixing part 14 is provided on the rear side of the first connector 1, and the fixing part 14 is provided with a fixing slot 141, which communicates with the insertion slot 311. First buckles 313 are provided on both sides of the first PCB board 31, and first slots 142 are provided on both sides of the fixing slot 141. The first buckles 313 engage with the first slots 142 to fix the first PCB board 31 in the fixing slot 141. In this way, the first PCB board 31 can be inserted and assembled from the rear side of the first connector 1, and after assembly, it is stably fixed by the engagement between the first buckles 313 and the first slots 142. The connection between the fixing slot 141 and the insertion slot 311 also facilitates the formation of an insertion bearing area associated with the insertion slot 311 at the front end of the first PCB board 31.
[0037] The first socket 33 is provided with a first pin array 331. The first pin array 331 is inserted into and soldered onto the first PCB board 31, and is electrically connected to the contact spring array 32 through the circuit on the first PCB board 31. Thus, the first socket 33 can serve as the first functional interface of the module to the outside world. Its signal or current enters the first PCB board 31 through the first pin array 331, and is then transmitted to the contact spring array 32 by the circuit of the first PCB board 31, preparing for subsequent docking with the conductive contact array 43 inside the second connector 2.
[0038] Two sets of contact spring arrays 32 are arranged opposite each other. Spring slots 312 are provided on both sides of the insertion slot 311. The contact spring arrays 32 are disposed within the spring slots 312 and soldered to the first PCB board 31. That is, one set of contact spring arrays 32 is provided on each of the left and right sides of the insertion slot 311. This symmetrical arrangement allows the insertion part 411 in the second power connection assembly 4 to simultaneously contact the contact spring arrays 32 on both sides when inserted into the insertion slot 311, thereby forming a double-sided conductive connection.
[0039] The contact spring array 32 includes multiple conductive contact springs 321. Each conductive contact spring 321 has a friction contact portion 322 that is bent and protrudes into the insertion groove 311. The friction contact portion 322 is used to contact the conductive contact array 43. Because the friction contact portion 322 protrudes into the insertion groove 311, when the insertion part 411 enters the insertion groove 311, the conductive contact array 43 on both sides will form elastic frictional abutment with the friction contact portions 322 on both sides. This contact method helps to increase contact pressure, improve conductivity stability under minor assembly errors, and reduce the risk of poor contact in vibrating environments.
[0040] The second power connection assembly 4 includes a second PCB board 41, a second socket 42, and a conductive contact array 43. The second PCB board 41 is fixed inside the second connector 2. The second PCB board 41 has a protruding insertion portion 411. The conductive contact array 43 is disposed on both sides of the insertion portion 411. The second socket 42 is disposed on the second PCB board 41 and is electrically connected to the conductive contact array 43 through the circuit on the second PCB board 41. In this structure, the second PCB board 41 not only undertakes the installation and electrical connection functions of the external second socket 42, but also directly forms the insertion portion 411 at its front end. In other words, the front end of the second PCB board 41 can be partially extended to form a plate-shaped insertion portion 411, and the conductive contact array 43 is respectively arranged on the front and back sides of the insertion portion 411. When the second connector 2 is inserted into the first connector 1, the insertion portion 411 can be directly inserted into the insertion slot 311, and the conductive contact array 43 then forms double-sided conductive contact with the two sets of contact spring arrays 32. Compared with the traditional pin / socket form, this structure has several distinct features: First, the plug part 411 can be integrated with the second PCB board 41, reducing intermediate transition structures; second, the conductive contact array 43 is distributed on both sides, which can improve the channel integration capability per unit width; and third, the frictional contact relationship with the contact spring array 32 is clear, which facilitates the formation of stable contact.
[0041] The first insertion cavity 111 is provided with an insertion positioning groove 112, and the second insertion cavity 212 is provided with an insertion positioning rib 213, which is used to insert into the insertion positioning groove 112. This structure allows the second connector 2 to establish a directional guiding relationship through the cooperation between the insertion positioning rib 213 and the insertion positioning groove 112 when it is inserted into the first connector 1. This can avoid incorrect insertion direction of the second connector 2 and reduce the alignment deviation between the insertion part 411 and the insertion groove 311.
[0042] The insertion positioning groove 112 is provided with a positioning hole 113, and the insertion positioning rib 213 is provided with a positioning post 214. The positioning hole 113 is used to cooperate with the positioning post 214. That is, after the insertion positioning rib 213 enters the insertion positioning groove 112, the positioning post 214 further enters the positioning hole 113, thereby more accurately defining the final insertion position. This not only improves the mechanical alignment accuracy, but also ensures that the multiple sets of conductive contact arrays 43 and the multiple sets of contact spring arrays 32 make one-to-one contact.
[0043] A sealing groove 215 is provided on the outer periphery of the connector 211, and a sealing ring 216 is provided inside the sealing groove 215. When the connector 211 is inserted into the first insertion cavity 111, the sealing ring 216 abuts against the inner wall of the first insertion cavity 111. Thus, while the mechanical insertion is completed, a circumferential seal is also formed in the connection area, which helps to improve the dustproof and moisture-proof adaptability of this module in photovoltaic inverter applications.
[0044] Two first card connectors 12 are provided, and the two first card connectors 12 are respectively provided on both sides of the first insertion part 11. An insertion guide groove 121 is provided between the first card connector 12 and the first insertion cavity 111.
[0045] Two second locking members 22 are provided, one on each side of the second insertion portion 21. The second locking members 22 are used to insert into the insertion guide groove 121. That is, in addition to the internal insertion connector 211 entering the first insertion cavity 111, the second locking members 22 on both sides of the second connector 2 also advance synchronously along the insertion guide groove 121. This double-sided guiding structure helps improve the overall stability and lateral stability of the insertion.
[0046] The first connector 12 is provided with a insertion slot 122, and the outer side of the second connector 22 is provided with a insertion buckle 221, which is used to engage with the insertion slot 122. When the second connector 2 is inserted into place, the insertion buckle 221 on the second connector 22 will engage with the insertion slot 122 on the first connector 12, thereby forming a first-level insertion retention structure.
[0047] The outer periphery of the second connector 2 is provided with a limiting rib 24, which is used to limit the insertion of the plug 211 into the first plug cavity 111. By contacting the corresponding part of the first connector 1 with the limiting rib 24, the insertion depth of the second connector 2 can be limited to prevent over-insertion or under-insertion. The second snap-fit member 22 is provided on the limiting rib 24 and extends rearward. The tail of the second snap-fit member 22 is provided with a pressing part 222. The pressing part 222 facilitates the application of force when disassembly is required, so that the plug latch 221 disengages from the plug slot 122, thereby releasing the first snap-fit relationship.
[0048] The first locking component 13 includes a locking platform 131 and a locking hole 132 disposed on the locking platform 131, wherein a nut post 133 is disposed in the locking hole 132. The second locking component 23 includes a mounting boss 231 and a locking bolt 232 disposed on the mounting boss 231. The locking bolt 232 is mounted on the mounting boss 231 and is used to cooperate with the nut post 133 to realize the locking connection between the first connector 1 and the second connector 2.
[0049] This means that after the snap-fit is completed, a second locking can be achieved by the engagement between the locking bolt 232 and the nut post 133, thereby securing the first connector 1 and the second connector 2. This locking method is particularly suitable for applications requiring higher mechanical holding forces, such as vibration environments, long-term outdoor environments, or high-reliability module connection scenarios.
[0050] The locking bolt 232 is equipped with a return spring 233, which applies pressure to the locking bolt 232 toward the rear side of the second connector 2. This allows the locking bolt 232 to automatically return to its original position when not tightened or loosened, facilitating repeated assembly and operation.
[0051] The second connector 2 includes a housing 25 and an inner housing 26. The inner housing 26 is fixed inside the housing 25, and the second PCB board 41 is fixed on the inner housing 26. Second latches 412 are provided on both sides of the second PCB board 41, and the inner housing 26 is provided with second slots 261. The second latches 412 engage with the second slots 261 to fix the second PCB board 41 inside the inner housing 26. In this way, the second PCB board 41 can obtain stable support inside the second connector 2 and maintain the predetermined positional relationship between the insertion part 411 and the connector 211.
[0052] The second socket 42 is an RJ socket, and it is equipped with a resilient pin 421. The second PCB board 41 is equipped with a pin hole 413 for inserting the resilient pin 421. Thus, the standard RJ socket interface structure can be integrated into this connector module, facilitating connection to external communication lines or standard network cables.
[0053] The second PCB board 41 is equipped with a DIP switch 414 and a resistor 415. The conductive contact array 43 is connected to the second socket 42 via the DIP switch 414 and the resistor 415. In this way, while completing the basic conductive connection, the DIP switch 414 can also be used to select functions, configure resistance values, or switch signal paths, giving this module a certain ability to expand its additional circuit functions.
[0054] During actual insertion, the second connector 2 moves towards the first connector 1. Initially, the insertion positioning rib 213 enters the insertion positioning groove 112, and the insertion part 211 enters the first insertion cavity 111. During insertion, the sealing ring 216 gradually forms a sealing contact with the inner wall of the first insertion cavity 111. As insertion continues, the insertion part 411 enters the insertion groove 311, and the conductive contact array 43 forms a double-sided friction contact with the contact spring arrays 32 on both sides. After insertion, the insertion latch 221 on the second latch 22 engages with the insertion slot 122 on the first latch 12, completing the first layer of retention. If further reinforcement is needed, the locking bolt 232 and the nut post 133 can be engaged to form a second layer of locking connection.
[0055] In the conductive path, the first socket 33 and the contact spring array 32 are electrically connected via the first PCB board 31, and the second socket 42 and the conductive contact array 43 are electrically connected via the second PCB board 41. Therefore, after insertion, a stable multi-path conductive connection between boards or modules can be formed. If a DIP switch 414 and a resistor 415 are provided on the second PCB board 41, functional configuration can also be achieved in the connection path.
[0056] This invention organically combines a plug-in guiding structure, a double-sided conductive contact structure, a dual holding structure, and a PCB circuit functional integration structure to form an integrated connector module particularly suitable for photovoltaic inverter applications. This module not only possesses high mechanical connection stability, multi-channel conductive connection capability, and environmental adaptability, but also facilitates standard interface integration and additional function expansion, making it highly practical and worthy of widespread application.
[0057] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
