Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation, and in particular to a photovoltaic module MC4 connector removal pliers. Background Art

[0002] PV panels and inverters typically use MC4 connectors. MC4 connectors are commonly used in solar PV systems, connecting PV panels, combiner boxes, and other components to the inverter. Disassembly of MC4 connectors is often necessary when performing maintenance or replacing components in solar PV systems. MC4 connectors consist of a male and female connector and utilize a plug-in electrical connection secured by a snap-on clip. Disassembly requires separating the male connector from the female connector.

[0003] Due to the size limitation of the connector, it is difficult for the operator to accurately apply force to the buckle in the groove when directly pressing the buckle of the male connector. Moreover, when the MC4 connector is in the connected state, even if the buckle is pressed, the static friction between the male connector and the female connector is still very large. It takes a lot of pulling force to directly pull the two connectors apart with both hands, which makes it difficult to apply force and difficult to disassemble. Utility Model Content

[0032] Inverter connectors in solar photovoltaic systems typically use MC4 connectors. MC4 connectors provide a stable and reliable connection, ensuring smooth current transmission. MC4 connectors connect components such as photovoltaic panels, combiner boxes, and inverters in solar photovoltaic systems. Disassembly of MC4 connectors is often necessary for maintenance or component replacement in solar photovoltaic systems. MC4 plugs consist of a male and female connector, secured together by an inverted triangle-shaped snap-fit bayonet. Disassembly requires separating the male connector from the female connector.

[0033] Due to the size limitation of the connector, it is difficult for the operator to accurately apply force to the buckle inside the bayonet when directly pressing the buckle of the male connector. Moreover, when the MC4 connector is in the connected state, even if the buckle is pressed, the static friction between the male connector and the female connector is still very large. It takes a lot of pulling force to directly pull the two connectors apart with both hands, which makes it difficult to apply force and difficult to disassemble.

[0034] Therefore, the inventors proposed a photovoltaic module MC4 connector removal pliers to solve the problem of difficult inverter connector removal.

[0035] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] Figure 1 A schematic diagram of the structure of the photovoltaic module MC4 connector removal pliers provided in an embodiment of the present application; Figure 2 A cross-sectional view of the photovoltaic module MC4 connector removal pliers buckle clamping assembly and the connector clamping assembly provided in an embodiment of the present application; Figure 3 A schematic diagram of the internal structure of the photovoltaic module MC4 connector removal pliers provided in an embodiment of the present application; Figure 4 A schematic diagram of the split state of the second shell of the photovoltaic module MC4 connector removal pliers provided in an embodiment of the present application; Figure 5 A schematic diagram of the clamping state of the photovoltaic module MC4 connector removal pliers provided in an embodiment of the present application after the first action is completed; Figure 6 This is a schematic diagram of the separation state of the photovoltaic module MC4 connector removal pliers provided in an embodiment of the present application after the second action is completed.

[0037] Reference Figures 1 to 6 As shown, an embodiment of the present application provides a photovoltaic module MC4 connector removal pliers, comprising: a snap clamping assembly, a connector clamping assembly, a handle 1, a spring 2 and a central axis 3; the snap clamping assembly and the connector clamping assembly both include a pliers housing, a transmission assembly and a clamping structure; the number of handles 1 is two, and the spring 2 is arranged between the handles 1 and the two ends are detachably connected to the handles 1.

[0038] Specifically, the buckle clamping assembly is used to clamp the buckles on both sides of the male and female connectors, facilitating their release and allowing the connectors to be easily separated. After the buckles are released, the buckle clamping assembly will clamp the male connector. The connector clamping assembly is used to stabilize and secure the female connector. Spring 2, located between handles 1, accumulates energy when handles 1 are squeezed, and helps rebound handles 1 when released. Central axis 3 is the center point of the rotational connection between the buckle clamping assembly and the connector clamping assembly, allowing the removal pliers to operate like scissors to separate the male and female connectors.

[0039] The caliper housing includes a first shell 4 and a second shell 5. The first shell 4 is fixed perpendicular to the second shell 5, and the transmission assembly is arranged inside the caliper housing; the snap clamping assembly and the second shell 5 of the joint clamping assembly are rotatably connected through the central axis 3; the handle 1 is rotatably connected to the central axis 3; the clamping structure is slidably arranged at the end of the caliper housing away from the handle 1.

[0040] Specifically, the first and second housings 4, 5, are vertically fixed to each other, providing support for the transmission assembly and the clamping structure. The accommodating cavity within the first housing 4 effectively maintains the relative position of the transmission assembly, preventing any movement that could affect transmission performance. A through-hole connects the first and second housings 4, 5, allowing the second pull rod 7 to pass through and thereby transmit force.

[0041] The transmission assembly includes a first pull rod 6, a second pull rod 7, a third pull rod 8 and a half gear 9; the first pull rod 6 is rotationally connected to the handle 1 and the second pull rod 7 respectively, the third pull rod 8 is rotationally connected to the half gear 9 and the end of the second pull rod 7 away from the first pull rod 6 respectively, and the half gear 9 is engaged with the clamping structure.

[0042] Specifically, the transmission assembly transmits the movement of the handle 1 to the clamping structure, enabling it to clamp or release the joint. The clamping mechanism is driven by the half gear 9 to clamp the joint.

[0043] The embodiment of the present application provides a photovoltaic module MC4 connector removal pliers, which completes the first action by initially pressing the handle 1 using the transmission assembly, so that the buckle clamping assembly and the connector clamping assembly respectively clamp the buckle and the connector, so that the buckle is detached; based on the initial pressing of the handle 1, the handle 1 is pressed again through the center axis 3 to complete the second action so that the buckle clamping assembly and the connector clamping assembly are separated like scissors, completing the disassembly of the MC4 connector; the connector is quickly disassembled through the two actions of the disassembly pliers, which effectively simplifies the difficulty of joint disassembly and improves the disassembly efficiency.

[0044] In some embodiments, the clamping structure of the above-mentioned snap clamping assembly includes a pair of clamps 10 and a pair of snap clamp heads 11; one end of the clamp 10 is fixed to the snap clamp head 11, and the other end is engaged with the half gear 9 through a tooth groove.

[0045] Specifically, the snap pliers head 11 is used to directly contact and release the snap. The other end of the clamping plate 10 is provided with a toothed groove that meshes with the teeth on the half gear 9. When the half gear 9 rotates, its teeth push or pull the toothed groove on the clamping plate 10, thereby moving the clamping plate 10 and the snap pliers head 11. The teeth of the half gear 9 mesh with the toothed groove on the clamping plate 10, converting the user's manual operation into the opening and closing movement of the clamping plate 10.

[0046] During use, when handlebar 1 is initially pressed toward the center, first pull rod 6 drives second pull rod 7 toward central axis 3, which then drives third pull rod 8, ultimately causing half gear 9 to rotate. This rotation of half gear 9 drives the teeth on clamping plate 10, causing clamping plate 10 to move in the direction of engagement between the teeth and the gear teeth. This movement of clamping plate 10 closes the clamping jaws 11, thereby clamping the clamp and releasing it from the retaining socket.

[0047] In some embodiments, the snap pliers head 11 is rectangular.

[0048] Specifically, the rectangular clamp head 11 and the abutment surface of the buckle are flat, which can effectively press the buckle out of the bayonet. The shape and size of the clamp head 11 can also be adjusted according to the specific type of connector buckle to ensure that the buckle can be effectively clamped or released.

[0049] In some embodiments, the clamping structure of the joint clamping assembly includes a pair of clamping plates 10 and a pair of joint clamp heads 12; one end of the clamping plate 10 is fixed to the joint clamp head 12, and the other end is engaged with the half gear 9 through a tooth groove.

[0050] Specifically, the joint clamp head 12 is used to stabilize and secure the joint. The teeth on the other end of the clamping plate 10 mesh with the teeth on the half gear 9. When the half gear 9 rotates, its teeth drive the teeth on the clamping plate 10, thereby moving the clamping plate 10 and the clamping clamp head 11. The teeth of the half gear 9 mesh with the teeth on the clamping plate 10, converting the user's manual operation into the opening and closing of the clamping plate 10.

[0051] During use, when handlebar 1 is initially pressed toward the center, first tie rod 6 drives second tie rod 7 toward central axis 3, which then drives third tie rod 8, ultimately causing half gear 9 to rotate. This rotation of half gear 9 drives the teeth on clamping plate 10, causing it to move in the direction of engagement between the teeth and the gear teeth. This movement of clamping plate 10 closes joint jaws 12, tightening the joint and ensuring a uniform and stable grip.

[0052] In some embodiments, the connector clamp head 12 is provided with an arc-shaped notch 13 , and the size of the arc-shaped notch 13 matches the size of the inverter plug.

[0053] Specifically, the size of the arc-shaped notch 13 matches the outer contour of the inverter plug, ensuring that the connector clamp head 12 can correctly adapt to the shape of the connector, thereby providing stable clamping during operation; at the same time, it helps to disperse the clamping force and reduce damage to the connector.

[0054] The arc-shaped notch 13 can also be treated with anti-slip treatment, such as providing anti-slip protrusions or anti-slip rubber strips, to reduce accidental sliding or joint detachment.

[0055] In some embodiments, a clamping platform 14 is provided at the position of the handle 1 corresponding to the spring 2 , the diameter of the clamping platform 14 matches the inner diameter of the spring 2 , and both ends of the spring 2 are clamped and fixed to the clamping platform 14 and the ends are in contact with the handle 1 .

[0056] Specifically, the clamping table 14 is used to position and fix the spring 2. By setting the diameter to match the inner diameter of the spring 2, the spring 2 can be accurately mounted on the clamping table 14, ensuring that the spring 2 will not shift during operation.

[0057] The spring 2 is located between the two handles 1 and can provide resistance and assistance to help the operator more easily control the clamping force and make the jaws rebound quickly when the handles 1 are released, making it easier for the user to operate the handles 1 and reducing the effort required for the operation.

[0058] The secure connection between the clamping platform 14 and the spring 2 reduces wear on the spring 2 during repeated use, extending the tool's service life. The stable connection of the spring 2 reduces the risk of unexpected situations during operation, such as spring 2 falling off or losing its elasticity, and improves tool safety. When spring 2 needs to be replaced, the detachable connection makes maintenance and replacement simple and quick.

[0059] In some embodiments, a movable slot 15 is formed at a position of the first housing 4 corresponding to the clamping plate 10 .

[0060] Specifically, the movable groove 15 provides the necessary movable space for the splint 10, ensuring the smooth operation of the clamping assembly, ensuring the stability of the splint 10 during movement, reducing swinging or deviation during operation, and improving the accuracy of operation.

[0061] In some embodiments, a sliding groove 16 is provided at one end of the first shell 4 close to the clamping structure, and a slide plate 17 is provided on the clamping plate 10 . The clamping plate 10 and the first shell 4 slide together through the sliding groove 16 and the slide plate 17 .

[0062] Specifically, the matching design of the chute 16 and the slide plate 17 ensures smooth sliding of the splint 10 during operation, avoiding jamming or uneven movement. At the same time, the chute 16 provides precise direction guidance for the splint 10, improving the accuracy of operation.

[0063] In some embodiments, the handle 1 is L-shaped.

[0064] Specifically, the L-shaped handle 1 provides a better leverage effect, allowing the operator to achieve a greater clamping force with less force, thereby reducing the difficulty of operation.

[0065] In some embodiments, the first pull rod 6 is rotatably connected to the inflection point of the handle 1 .

[0066] Specifically, the first pull rod 6 is rotationally connected to the inflection point of the handle 1, so that the pull rod can rotate smoothly with the movement of the handle 1, ensuring smooth transmission of the action, reducing friction and jamming during operation, and at the same time increasing stability during operation, ensuring uniform distribution and control of force.
