Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic connectors, in particular to an adjustable photovoltaic assembly connector. Background Art

[0002] PV panel connectors are core components for achieving electrical connections between PV panels. Their performance directly impacts the efficiency and safety of PV systems. They connect PV panels to junction boxes, inverters, combiner boxes, and other equipment, making them an essential component of solar power generation systems.

[0003] However, this photovoltaic connector has the following defects when used: 1. When connecting photovoltaic modules (photovoltaic panels) and junction boxes, existing photovoltaic connectors require plugging and unplugging the male connector of the connector and the female connector of the junction box to complete the connection. The squeezing force during plugging and unplugging directly acts on the conductive parts inside the female connector, which can easily cause the horn-shaped end of the conductive part to deform and open due to direct squeezing force. The contact surface of the conductive part is prone to misalignment, causing a false connection and affecting the conductivity. At the same time, the deformed conductive part will weaken the clamping effect of the pins inside the male connector, making the male connector prone to falling off or loosening. 2. When connecting photovoltaic modules (photovoltaic panels) and junction boxes, the main function of existing photovoltaic connectors is to transmit the converted electrical energy to the inverter in a safe manner (through the integration and regulation of the components inside the junction box). However, during actual assembly and use, due to the conductive connection and transmission of multiple photovoltaic modules, the increased contact resistance of the conductive end can cause localized high temperatures in the conductive units inside the photovoltaic connector, and even cause arcing or fire, resulting in low safety.

At the same time, the conductive copper tubes that correspond one-to-one with the conductive pins of the conductive male connector can be displaced to a certain extent and contact the spring sheet. On the one hand, this reduces the squeezing force when the conductive pins of the conductive male connector are directly inserted into the conductive copper tube, and reduces the deformation of the conductive copper tube end portion (trumpet-shaped) due to excessive squeezing force when plugging and unplugging the conductive male connector, thereby ensuring the contact area size and conductivity of the conductive copper tube and the pin portion. On the other hand, because the probability of deformation of the conductive copper tube is reduced, the conductive copper tube can more stably clamp and fix the conductive pin portion of the conductive male connector, and the plug-in and conductive connection between the two are not prone to disconnection or contact failure, which is highly safe. 2. In the adjustable photovoltaic module connector, when transmitting photovoltaic current, the discharge protection module and the charging protection module are designed to provide safety protection for the photovoltaic current during transmission, reducing the probability of local high temperature, arcing or fire during photovoltaic current transmission, and providing high safety. At the same time, two sets of discharge protection modules and charging protection modules are provided. A pair of electrically connected discharge protection modules and charging protection modules are set inside an insulating shell. In conjunction with the charge and discharge hub module, the two L-shaped female connectors connected to a charge and discharge conductive socket can be used as charging or discharging units at will, effectively avoiding the problem of misplugging when electrically connecting to the conductive male connector. 3. In the adjustable photovoltaic module connector, the conductive strip design can transmit photovoltaic current to the charging and discharging module for current regulation and integration, ensuring the safety of photovoltaic current transmission. On the other hand, compared with traditional current transmission methods (such as conductive connections of pins), it ensures extremely low resistivity, resulting in minimal current loss during transmission, improving energy efficiency. It also has good flexibility and bendability, can adapt to the installation requirements of various complex shapes, and ensure the stability and efficiency of current transmission. 4. In the adjustable photovoltaic module connector, the hourglass-shaped internal concave and convex parts are set inside the conductive copper tube and the insulating embedded tube (the internal concave and convex parts inside the insulating embedded tube can cooperate with the displacement of the conductive copper tube and match the internal concave and convex parts of the conductive copper tube). On the one hand, the insulation effect of the insulating embedded tube on the conductive copper tube and the photovoltaic current transmission is improved. On the other hand, when the conductive copper tube is displaced, it will only displace in the horizontal direction (no rotation), effectively improving the safety of plugging and unplugging conductive transmission.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application. Example 1

[0019] See also Figures 1-15The adjustable photovoltaic module connector includes a photovoltaic base 10: a photovoltaic cover 20 installed on the top of the photovoltaic base 10 by screws; a charging and discharging assembly 30 installed on one side of the inner wall of the photovoltaic base 10 by screws; a photovoltaic conductive connecting mechanism 40 electrically connected to the charging and discharging assembly 30 and installed on the bottom of the photovoltaic base 10; a cable connector 50 plugged into and conductively connected to the photovoltaic conductive connecting mechanism 40, the cable connector 50 is electrically connected to the photovoltaic panel, and the photovoltaic conductive connecting mechanism 40 includes: a plug fixed to the side of the charging and discharging assembly 30 and electrically connected to the charging and discharging assembly 30 A conductive transmission component 401; an electrical protection component 402 electrically connected to the conductive transmission component 401 and installed at the bottom of the photovoltaic base 10 by screws; a female component 403 electrically connected to the top of the electrical protection component 402 and extending to the inner wall of the photovoltaic base 10; a plurality of conductive copper tubes 404 assembled inside the female component 403; an insulating embedded tube 405 sleeved on the outside of the conductive copper tube 404 and installed inside the female component 403, the interior of the conductive copper tube 404 is electrically connected to a cable connector 50, and the cable connector 50 and the female component 403 are plugged and fixed.

[0020] The operating principle described above is as follows: When plugging and unplugging the cable connector 50 connected to the photovoltaic module (photovoltaic panel), the pins inside the cable connector 50 are inserted into the conductive copper tube 404 inside the female connector assembly 403. The transmitted current is then conveyed through the conductive copper tube 404 to the interior of the electrical protection assembly 402. The current is then integrated and regulated by the components within the electrical protection assembly 402, forming a current suitable for power storage and inversion, which is then transmitted to the charging and discharging assembly 30 (via the conductive transmission assembly 401). At this point, another set of conductive transmission assemblies 401, electrical protection assembly 402, and female connector assembly 403, electrically connected to the side of the conductive transmission assembly 401, can transmit the regulated and integrated current to the cable connector 50 connected to the inverter and power storage device, achieving highly safe photovoltaic current transmission operations. Among them, through multiple conductive copper tubes 404 and electrical protection components 402, large currents during transmission can be safely protected, the contact resistance of the conductive end can be reduced, and the high temperature of the charging and discharging component 30 caused by the increase of current and resistance can be avoided, thereby improving the safety of current transmission to photovoltaic components (photovoltaic panels).

[0021] Specific reference Figure 5 、 Figure 6 and Figure 7The charging and discharging assembly 30 includes: a bottom seat 301 that is snap-fitted and fixed to the bottom of the photovoltaic base 10; an L-shaped base frame 302 installed on the top of the bottom seat 301 by screws; an L-shaped top frame 303 that abuts the top of the L-shaped base frame 302; a top seat 304 installed on the top of the L-shaped top frame 303 by screws; a charging and discharging module 305 arranged between the L-shaped top frame 303 and the L-shaped base frame 302; a charging and discharging conductive seat 306 installed inside the charging and discharging module 305 by screws; and a charging and discharging conductive part 307 that is arranged on the upper and lower sides inside the charging and discharging conductive seat 306 and is electrically connected to the charging and discharging module 305, wherein a conductive transmission assembly 401 is installed inside the charging and discharging conductive seat 306, and two groups of charging and discharging conductive seats 306 are provided.

[0022] In this solution, a bottom plug 3021 extending to the middle part of the charging and discharging module 305 is installed at the center of the top of the L-shaped base frame 302. A top socket 3031 is fixed to the top of the bottom plug 3021, and the top socket 3031 is installed at the center of the bottom of the L-shaped top frame 303.

[0023] In the adjustable photovoltaic module connector of the present invention, the design of the bottom plug 3021 and the top socket 3031 inside the L-shaped bottom frame 302 and L-shaped top frame 303 allows the charging and discharging module 305 to be positioned and fixed between the L-shaped bottom frame 302 and L-shaped top frame 303, ensuring that the charging and discharging module 305 can be stably and securely assembled between the bottom base 301 and the top base 304. At the same time, the charging and discharging module 305 can regulate and integrate the charging and discharging operations of the current, ensuring the safety of the photovoltaic current transmission.

[0024] Specific reference Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The conductive transmission component 401 includes: a charge and discharge plug connector 4011 connected to the charge and discharge conductive seat 306 through screws; a bottom conductive head 4012 electrically connected to the charge and discharge plug connector 4011; a conductive belt 4013 electrically connected to the bottom conductive head 4012 and extending to the outside of the bottom conductive head 4012; a downward pressure socket 4014 electrically connected to the conductive belt 4013; and an electrical protection component 402 electrically connected to the downward pressure socket 4014, wherein the charge and discharge plug connector 4011 is electrically connected to the charge and discharge conductive part 307.

[0025] In this solution, the central part inside the pressure down socket 4014 is electrically connected to the pressure down pin 40141, and the left and right sides of the pressure down pin 40141 are provided with guide rods 40142 installed in the eccentric part of the bottom of the pressure down socket 4014. The bottom of the pressure down pin 40141 is electrically connected to the electrical protection component 402, and the guide rods 40142 extend to the interior of the electrical protection component 402.

[0026] In the adjustable photovoltaic module connector of the present invention, the design of guide rod 40142 ensures that push-down pin 40141 within push-down socket 4014 will not misalign or shift when inserted into electrical protection assembly 402, providing enhanced safety. Furthermore, the structural design of conductive strip 4013, compared to traditional structures, not only ensures extremely low resistivity, minimizing current loss during transmission and improving energy efficiency, but also offers excellent flexibility and bendability, adapting to various complex installation requirements and ensuring stable and efficient current transmission.

[0027] Specific reference Figure 10 and Figure 11 The electrical protection component 402 includes: an insulating shell 4021 installed at the bottom of the photovoltaic base 10 by screws; a charging protection module 4022 arranged on one side of the inside of the insulating shell 4021; a discharge protection module 4024 electrically connected to the charging protection module 4022 through a wire 4023 and installed on the other side of the inside of the insulating shell 4021, wherein the top of the charging protection module 4022 is electrically connected to the upper conductive head 40220, the upper conductive head 40220 extends to the outside of the insulating shell 4021, and the upper conductive head 40220 is electrically connected to the down-pressing socket 4014 through the down-pressing pin 40141, wherein guide rods 40142 are movably provided on the left and right sides of the inside of the upper conductive head 40220, and the top of the discharge protection module 4024 is electrically connected to the female head component 403.

[0028] In this solution, the top of the insulating shell 4021 is in contact with a downward pressure bracket 40221, and the downward pressure bracket 40221 is installed on the inner bottom of the photovoltaic base 10 by screws. There are multiple wires 4023, and the outer sides of the multiple wires 4023 are in contact with a wire-fixing bracket 40231, which is installed on the inner bottom of the photovoltaic base 10 by screws.

[0029] In the adjustable photovoltaic module connector of the present invention, the design of two sets of charging protection modules 4022 and discharging protection modules 4024 safely protects the current generated during the charging and discharging processes, ensuring the safety of current transmission. Furthermore, each insulating housing 4021 is equipped with a charging protection module 4022 and a discharging protection module 4024, ensuring that current regulation, integration, and transmission are possible regardless of whether the cable connector 50 is inserted forward or reverse, preventing damage to the photovoltaic connector due to incorrect insertion.

[0030] Specific reference Figure 11 and Figure 12The female connector assembly 403 includes: an L-shaped female connector 4031 installed on the top of the insulating shell 4021 by screws and electrically connected to the discharge protection module 4024; a charge and discharge hub module 4032 installed inside the L-shaped female connector 4031; and plug-in pins 4033 electrically connected to the side of the charge and discharge hub module 4032, wherein the plug-in pins 4033 extend to the interior of the conductive copper tube 404, and the plug-in pins 4033 are installed on the outside of the bottom of the insulating embedded tube 405. The upper and lower sides of the L-shaped female connector 4031 are provided with a snap-in seat 40311 installed on the inner wall of the photovoltaic base 10.

[0031] In this solution, the insulating embedded tube 405 is equidistantly installed inside the protective sleeve 4051, the protective sleeve 4051 is installed inside the L-shaped female connector 4031 and is located on the side of the charging and discharging central module 4032, and a socket ring 4052 is provided on the side of the protective sleeve 4051. The socket ring 4052 is installed inside the L-shaped female connector 4031 and multiple conductive copper tubes 404 are penetrated inside. Among them, a sealing cover 4053 is clamped and fixed on the side of the socket ring 4052 away from the protective sleeve 4051, and the sealing cover 4053 is provided inside the L-shaped female connector 4031.

[0032] In the above solution, the design of the protective sleeve 4051 allows for the assembly and positioning of the insulating inner tube 405 disposed therein, ensuring that the insulating inner tube 405 is not easily displaced by the forces of insertion and removal during the insertion and removal of the cable connector 50, thereby enhancing safety. Furthermore, the design of the sleeve ring 4052 and the sealing cover 4053 respectively position and assemble the conductive copper tube 404, reducing the gap size during assembly of the conductive copper tube 404 and ensuring a strong seal.

[0033] In the adjustable photovoltaic module connector of the present invention, when current is transmitted, the transmitted current can be transmitted through the cable connector 50 to the conductive copper tube 404 electrically connected to it, and then transmitted through the conductive copper tube 404 to the plug pin 4033 and the charge-discharge hub module 4032. At this time, the charge-discharge hub module 4032 detects the charging or discharging operation of the current and uses the corresponding module to implement the charging or discharging operation. In addition, the current transmitted to the charge-discharge hub module 4032 can be transmitted to the charging protection module 4022 and the discharge protection module 4024 electrically connected to its bottom, implementing the charging and discharging protection operation.

[0034] Specific reference Figure 14 and Figure 15The cable connector 50 includes: a conductive male connector 501 extending into the interior of the conductive copper tube 404 and electrically connected to the conductive copper tube 404, the conductive male connector 501 extending into the interior of the L-shaped female connector 4031; a photovoltaic cable 502 electrically connected to the bottom of the conductive male connector 501; a photovoltaic connector 503 electrically connected to the photovoltaic cable 502, the photovoltaic connector 503 electrically connected to the photovoltaic panel, wherein the upper and lower sides of the conductive male connector 501 are equipped with snap-in connectors 5011 extending into the interior of the snap-in seat 40311.

[0035] In the adjustable photovoltaic module connector of the present invention, when plugging and unplugging the conductive male connector 501, the snap connector 5011 is inserted into the snap connector 40311 to secure the conductive male connector 501 and the L-shaped female connector 4031, making operation convenient. The photovoltaic connector 503 can also be connected to photovoltaic modules (photovoltaic panels), inverters, or storage modules as required, enabling the transmission and storage of photovoltaic current. Example 2

[0036] During use, it was discovered that when the conductive male connector 501 is inserted into the L-shaped female connector 4031, while the photovoltaic current is protected by the charge-discharge protection structure within the photovoltaic module connector, the direct insertion of the conductive male connector 501 generates a linear extrusion force within the L-shaped female connector 4031, directly acting on the conductive copper tube 404 (primarily on its inner wall). This direct extrusion force can cause the end portion (flared shape) of the conductive copper tube 404 to deform and open, and the contact surface of the conductive copper tube 404 can easily misalign and cause a loose connection, affecting conductivity. Furthermore, damage to the mechanical structure of the conductive copper tube 404 reduces the clamping force on the internal pins of the conductive male connector 501, making the conductive connection between the two vulnerable to disconnection, which can easily lead to leakage or arc discharge accidents, thus compromising safety.

[0037] For this purpose, refer specifically to Figure 16 A reserved opening 60 is provided on the inner wall of the insulating embedded tube 405. An insulating protrusion 601 mounted on the outside of the conductive copper tube 404 is movably connected to the inside of the reserved opening 60. The side of the insulating protrusion 601 contacts a spring piece 602 mounted inside the protective sleeve 4051. At the same time, multiple insulating protrusions 601 are installed on the outside of the plug-in pin 4033. The insulating protrusions 601 are slidably connected to the reserved opening 60 on the inner wall opening of the insulating embedded tube 405. Sufficient space is left inside the conductive copper tube 404 for the plug-in pin 4033 to move, and the plug-in pin 4033 is always electrically connected to the conductive copper tube 404 when moving.

[0038] In the adjustable photovoltaic module connector of the present invention, the conductive copper tube 404, which can move a certain distance, and the spring piece 602 that elastically supports the conductive copper tube 404 (which performs a reset and buffering function), can be directly inserted into the conductive copper tube 404 to transmit electrical power. This buffers and reduces the direct extrusion force, reducing the pressure and damage to the end portion (flared shape) of the conductive copper tube 404 caused by the extrusion force, and reduces the problem of false connection caused by misalignment of the conductive copper tube 404, thereby ensuring the conductive performance of the conductive copper tube 404 and the conductive male connector 501 during the electrical connection. At the same time, because the damage to the end portion of the conductive copper tube 404 is reduced, the conductive copper tube 404 can effectively ensure that the conductive male connector 501 has a better grip on the pin portion of the conductive copper tube 404 when inserted into the conductive copper tube 404, making the conductive connection between the two less likely to break, and enhancing safety.

[0039] In addition, in the present invention, the conductive copper tube 404 and the insulating embedded tube 405 are both provided with hourglass-shaped inner concave and convex protrusions at the positions on one side of the inner part of the protective sleeve 4051, and the inner concave and convex protrusions inside the insulating embedded tube 405 can cooperate with the displacement of the conductive copper tube 404. On the one hand, it improves the assembly effect of the insulating embedded tube 405 on the conductive copper tube 404, and on the other hand, it ensures that the conductive copper tube 404 is only displaced in the horizontal direction during displacement and will not rotate, thereby effectively improving the safety when plugging and unplugging the conductive connection.

[0040] Without limitation, any person skilled in the art who is familiar with the technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the protection scope of the present invention.
