Description

Technical Field

[0001] The present invention relates to the technical field of cable connector equipment, and in particular to a photovoltaic connector adapted for cables of various specifications and a method of using the same. Background Art

[0002] Photovoltaic connectors, commonly known as flexible joints, are generally called optical connectors. Photovoltaic connectors are part of a solar cell component that connects a system circuit. They play the role of connecting components and drawing out current. Among them, photovoltaic panels are mostly used in vast terrains, such as the northwest region of my country.

[0003] Photovoltaic connectors that are compatible with cables of various specifications are mostly used in outdoor environments to connect solar panels to output lines. In order to adapt to cables of various specifications, connectors are mostly fixed by hooks. However, due to the large temperature difference in the application environment, the hooks inside the connector will deform under changes in high and low temperatures, and eventually the connection will be unstable. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a photovoltaic connector adapted to cables of various specifications, including a connecting mechanism, the connecting mechanism also includes a connecting cable, both ends of the connecting cable are fixedly connected to a device housing, and one end of the device housing away from the connecting cable is connected to a feed square tube;

[0005] The clamping mechanism includes a push spring fixedly connected to the inner wall of the device housing, an end of the push spring away from the device housing is fixedly connected to a push block, and the bottom of the push block is slidably connected to an extrusion plate;

[0006] The sealing mechanism comprises a U-shaped pressure frame slidably connected to the inner wall of the through hole of the feeding square tube, a pushing rod is fixedly connected to the inner wall of the feeding square tube, and a sliding rod is fixedly connected to the bottom of the pushing rod.

[0007] Preferably, the connection mechanism also includes a fixed bracket 1 fixedly connected to the side wall of the equipment housing, the end of the fixed bracket 1 away from the equipment housing is fixedly connected to the top of the feed square tube, and the bottom of the feed square tube is fixedly connected to a fixed bracket 2.

[0008] Preferably, the connection mechanism also includes a power board fixedly connected to the inner wall of the device housing, a control groove is opened on the inner wall of the device housing, and an output wire is inserted into the inner wall of the feed square tube.

[0009] Preferably, the clamping mechanism also includes an L-shaped plate fixedly connected to the top of the extrusion plate, a rotating bracket is rotatably connected to the inner wall of the feeding square tube, a clamping blade is fixedly connected to the inner wall of the rotating bracket, and the end of the rotating bracket away from the feeding square tube is in contact with the bottom of the L-shaped plate. Utilizing the characteristic that a layer of rubber skin is wrapped around the outside of the output wire, a clamping blade is arranged inside the equipment. When the extrusion plate moves downward, it will drive the L-shaped plate to contact the rotating bracket, forcing the rotating bracket to rotate downward with the connection point as the center, so that the clamping blade is tightly attached to the outer wall of the output wire. At this time, due to the inclined design of the clamping blade, the cutting edge of the clamping blade will press the rubber skin of the output wire to become concave under extrusion. When tension is generated on the outside of the output wire, the clamping blade will be affected by its own inclination, and will increase the clamping force on the output wire, thereby avoiding the equipment shaking with the wind due to strong wind in the application environment, causing the connection position between the wire and the connector to loosen.

[0010] Preferably, the clamping mechanism also includes a sliding groove opened on the inner wall of the device shell, a pressure slide plate is slidably connected to the inner wall of the control groove, a support rod is fixedly connected to the top of the pressure slide plate, and a control rotating plate is rotatably connected to the inner wall of the control groove. Taking advantage of the fact that most photovoltaic cables are copper wires and copper materials are easy to deform, a pushing spring is arranged inside the device. Before using the device, the outer rubber skin of one end of the output wire is peeled off to retain the copper core, and the copper core is penetrated into the device through the feeding square tube. When the copper core of the output wire contacts the outer wall of the pressure slide plate when penetrating, the thrust of the output wire will drive the support rod to move inward through the pressure slide plate, so that the support rod loses the restriction on the control rotating plate. At this time, the mechanical power accumulated by the pushing spring will force the extrusion plate to break through the restriction of the control rotating plate and move downward. The bottom of the extrusion plate presses the copper core of the output wire, so that the copper core of the output wire is compressed and deformed, and fits on the surface of the power board. Through the application of the above-mentioned components, the device can be applied to cables of various specifications, while changing the shape of the copper core inside the output wire to form a barb shape inside the device to avoid loosening of the interface due to thermal expansion and contraction.

[0011] Preferably, the sealing mechanism also includes a pressurized air bag fixedly connected to the inner wall of the feeding square tube, a fixing frame is fixedly connected to the bottom of the feeding square tube, a prying rod is rotatably connected to the inner wall of the fixing frame, the outer wall of the prying rod is rotatably connected to the inner wall of the sliding rod, and a U-shaped pressure frame is arranged inside the equipment by utilizing the characteristic that the rotating bracket moves downward during operation. When the rotating bracket moves downward, the U-shaped pressure frame will be pushed to move downward, and the corresponding end of the prying rod will be forced to move downward, and the prying rod will be restricted by the fixing frame, and the other end will be forced to drive the sliding rod to lift upward, so that the pushing rod squeezes the output wire upward, thereby realizing the clamping restriction on the outer end of the output wire, and avoiding the wire skin rupture caused by long-term wear at the clamping position of the clamping blade during long-term operation of the equipment, thereby affecting the connection stability of the equipment.

[0012] Preferably, the sealing mechanism also includes a gear rod fixedly connected to the side wall of the U-shaped pressure frame, a limited block fixedly connected to the side wall of the fixed bracket second, a limited sliding rod slidably connected to the inner wall of the limited block, and the end of the prying rod away from the sliding rod is rotatably connected to the inner wall of the U-shaped pressure frame. By utilizing the characteristic of the push rod moving upward to extrude the output wire, a pressurized air bag is arranged inside the equipment. When the push rod extrude the output wire, the output wire will synchronously extrude the pressurized air bag, and the pressurized air bag will be deformed to block the feeding port of the feeding square tube, thereby improving the sealing effect. The high sealing performance of the equipment can prevent the weathering and embrittlement of the wire skin, and provide a buffer space for the connection position between the equipment and the output wire to avoid the wire skin rupture due to multiple bending at the terminal. In addition, when the U-shaped pressure frame moves downward, the limit slide bar moves along the inner wall of the limit block, and when the U-shaped pressure frame moves down to the lowest point, the plane of the limit slide bar will contact the inner wall of the gear rod, limiting the rebound of the U-shaped pressure frame, avoiding the loose connection of the equipment after long-term operation due to insufficient internal spring pressure.

[0013] A photovoltaic connector adapted to cables of various specifications and a method for using the same include the following steps:

[0014] S1: Before using the present invention, the outer rubber skin of one end of the output wire is peeled off, the copper core is retained, and the copper core is inserted into the interior of the device through the feeding square tube;

[0015] S2: When the copper core of the output wire goes deeper and contacts the outer wall of the pressure slide, the thrust of the output wire will drive the support rod to move inward through the pressure slide, so that the support rod loses the restriction on the control rotating plate;

[0016] S3: The mechanical power accumulated by the push spring will force the extrusion plate to break through the limit of the control rotating plate and move downward. The bottom of the extrusion plate presses the copper core of the output wire, causing the copper core of the output wire to be compressed and deformed.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the fact that photovoltaic cables are mostly copper wires and copper materials are easily deformed. A push spring is arranged inside the device. Before using the device, the outer rubber skin of one end of the output wire is peeled off to retain the copper core, and the device is inserted into the device through the feeding square tube. When the copper core of the output wire contacts the outer wall of the pressure slide plate while going deeper, the thrust of the output wire will drive the support rod to move inward through the pressure slide plate, causing the support rod to lose the restriction on the control turn plate. At this time, the mechanical power accumulated by the push spring will force the extrusion plate to break through the restriction of the control turn plate and move downward. The bottom of the extrusion plate presses the copper core of the output wire, causing the copper core of the output wire to be deformed under pressure and fit to the surface of the power board. Through the application of the above components, the device can be applied to cables of various specifications while changing the shape of the copper core inside the output wire to form a barb shape inside the device to avoid loosening of the interface due to thermal expansion and contraction.

[0019] (2) The present invention utilizes the characteristic that a layer of rubber skin is wrapped around the outside of the output wire, and a clamping blade is arranged inside the device. When the extrusion plate moves downward, it will drive the L-shaped plate to contact the rotating bracket, forcing the rotating bracket to rotate downward with the connection point as the center, so that the clamping blade is tightly attached to the outer wall of the output wire. At this time, due to the inclined design of the clamping blade, the edge of the clamping blade will press the rubber skin of the output wire to be concave under extrusion. When tension is generated on the outside of the output wire, the clamping blade will be affected by its own inclination and will increase the clamping force on the output wire, thereby avoiding the strong wind in the application environment, causing the device to sway with the wind and causing the connection position between the wire and the connector to loosen.

[0020] (3) The present invention utilizes the characteristic that the rotating bracket moves downward during operation, and a U-shaped pressure frame is arranged inside the equipment. When the rotating bracket moves downward, it will push the U-shaped pressure frame to move downward, and force the corresponding end of the prying rod to move downward. The prying rod is restricted by the fixed frame, and will force the other end to drive the sliding rod to lift upward, so that the pushing rod squeezes the output wire upward, thereby achieving clamping restriction on the outer end of the output wire, avoiding the wire skin rupture caused by long-term wear at the clamping position of the clamping blade during long-term operation of the equipment, thereby affecting the connection stability of the equipment.

[0021] (4) The present invention utilizes the characteristic that the push rod moves upward to extrude the output wire, and a pressurized air bag is arranged inside the device. When the push rod extrude the output wire, the output wire will simultaneously extrude the pressurized air bag. At this time, the pressurized air bag will deform, blocking the feeding port of the feeding square tube, thereby improving the sealing performance of the device. While preventing the wire skin from weathering and becoming brittle, a buffer space is provided for the connection position between the device and the output wire, thereby preventing the wire skin from breaking due to multiple bending at the terminal. In addition, when the U-shaped pressure frame moves downward, the limit slide bar is displaced along the inner wall of the limit block, and when the U-shaped pressure frame moves downward to the lowest point, the plane of the limit slide bar will contact the inner wall of the gear rod, thereby limiting the rebound of the U-shaped pressure frame, thereby preventing the device from becoming loose due to insufficient internal spring pressure after long-term operation.

[0035] For example, see Figure 1 - Figure 3 The present invention is a photovoltaic connector adapted to cables of various specifications, including a connecting mechanism 1, wherein the connecting mechanism 1 also includes a connecting cable 101, both ends of the connecting cable 101 are fixedly connected to a device housing 102, and one end of the device housing 102 away from the connecting cable 101 is connected to a feed square tube 103;

[0036] The clamping mechanism 2 includes a push spring 201 fixedly connected to the inner wall of the device housing 102, an end of the push spring 201 away from the device housing 102 is fixedly connected to a push block 202, and a bottom of the push block 202 is slidably connected to an extrusion plate 203;

[0037] The sealing mechanism 3 comprises a U-shaped pressure frame 301 slidably connected to the inner wall of the through hole of the feeding square tube 103 , a push rod 302 is fixedly connected to the inner wall of the feeding square tube 103 , and a sliding rod 303 is fixedly connected to the bottom of the push rod 302 .

[0038] The connection mechanism 1 also includes a fixed bracket 104 fixedly connected to the side wall of the equipment housing 102, and the end of the fixed bracket 104 away from the equipment housing 102 is fixedly connected to the top of the feed square tube 103, and the bottom of the feed square tube 103 is fixedly connected to a fixed bracket 2 105.

[0039] The connection mechanism 1 also includes a power board 106 fixedly connected to the inner wall of the device housing 102 . A control groove 107 is opened on the inner wall of the device housing 102 . An output wire 108 is inserted into the inner wall of the inlet square tube 103 .

[0040] For example 2, please refer to Figure 4 - Figure 8 The present invention is a photovoltaic connector adapted to cables of various specifications. On the basis of Example 1, the clamping mechanism 2 also includes an L-shaped plate 204 fixedly connected to the top of the extrusion plate 203. A rotating bracket 205 is rotatably connected to the inner wall of the feeding square tube 103. A clamping blade 206 is fixedly connected to the inner wall of the rotating bracket 205. The end of the rotating bracket 205 away from the feeding square tube 103 is in contact with the bottom of the L-shaped plate 204. By utilizing the characteristic that the output wire 108 is wrapped with a layer of rubber skin, a clamping blade 206 is arranged inside the device. When the extrusion plate 203 moves downward, it will drive the L-shaped plate 204 contacts with the rotating bracket 205, forcing the rotating bracket 205 to rotate downward with the connection point as the center, so that the clamping blade 206 is tightly attached to the outer wall of the output wire 108. At this time, due to the inclined design of the clamping blade 206, the cutting edge of the clamping blade 206 will press the rubber skin of the output wire 108 to be concave under the extrusion. When the output wire 108 generates tension outside, the clamping blade 206 will increase the clamping force on the output wire 108 due to its own inclination, so as to avoid the device shaking with the wind due to the strong wind in the application environment, causing the connection position between the wire and the connector to become loose.

[0041] The clamping mechanism 2 also includes a sliding groove 207 opened on the inner wall of the device housing 102, a pressure slide 208 is slidably connected to the inner wall of the control groove 107, a support rod 209 is fixedly connected to the top of the pressure slide 208, and a control rotating plate 210 is rotatably connected to the inner wall of the control groove 107. Taking advantage of the fact that most photovoltaic cables are copper wires and copper materials are easily deformed, a push spring 201 is arranged inside the device. Before using the device, the outer rubber skin of one end of the output wire 108 is peeled off, the copper core is retained, and the output wire 108 is inserted into the device through the feeding square tube 103. When the copper core of the output wire 108 contacts the outer wall of the pressure slide 208 when it penetrates, the output wire 108 is pushed into the device. The thrust of the wire 108 will drive the support rod 209 to move inward through the compressed slide plate 208, so that the support rod 209 loses the restriction on the control rotating plate 210. At this time, the mechanical power accumulated by the push spring 201 will force the extrusion plate 203 to break through the restriction of the control rotating plate 210 and move downward. The bottom of the extrusion plate 203 presses the copper core of the output wire 108, so that the copper core of the output wire 108 is compressed and deformed, and fits on the surface of the power board 106. Through the application of the above components, the device can be applied to cables of various specifications, while changing the shape of the copper core inside the output wire 108, forming a barb shape inside the device to avoid loosening of the interface due to thermal expansion and contraction.

[0042] The sealing mechanism 3 also includes a pressurized air bag 304 fixedly connected to the inner wall of the feeding square tube 103, a fixing frame 305 is fixedly connected to the bottom of the feeding square tube 103, a prying rod 306 is rotatably connected to the inner wall of the fixing frame 305, and the outer wall of the prying rod 306 is rotatably connected to the inner wall of the sliding rod 303. Utilizing the characteristic that the rotating bracket 205 moves downward during operation, a U-shaped pressure frame 301 is arranged inside the device. When the rotating bracket 205 moves downward, it will push the U-shaped pressure frame 301 to move downward, and force the corresponding end of the prying rod 306 to move downward, and the prying rod 306 is restricted by the fixing frame 305, and will force the other end to drive the sliding rod 303 to lift upward, so that the pushing rod 302 squeezes the output wire 108 upward, thereby realizing the clamping restriction on the outer end of the output wire 108, and avoiding the wire skin rupture of the clamping position of the clamping blade 206 due to long-term wear during long-term operation of the equipment, thereby affecting the connection stability of the equipment.

[0043] The sealing mechanism 3 also includes a gear rod 307 fixedly connected to the side wall of the U-shaped pressure frame 301, a limit block 308 fixedly connected to the side wall of the fixed bracket 105, a limit slide bar 309 slidably connected to the inner wall of the limit block 308, and an end of the prying rod 306 away from the slide bar 303 is rotatably connected to the inner wall of the U-shaped pressure frame 301. By utilizing the characteristic that the push rod 302 moves upward to squeeze the output wire 108, a pressurized air bag 304 is arranged inside the device. When the push rod 302 squeezes the output wire 108, the output wire 108 will synchronously squeeze the pressurized air bag 304, and at this time the pressurized air bag 304 will be deformed to seal. The feeding port of the feeding square tube 103 improves the sealing performance of the equipment, and while preventing the wire skin from weathering and becoming brittle, provides a buffer space for the connection position between the equipment and the output wire 108, thereby preventing the wire skin from breaking due to multiple bending at the terminal. In addition, when the U-shaped pressure frame 301 moves downward, the limit slide bar 309 is displaced along the inner wall of the limit block 308, and when the U-shaped pressure frame 301 moves downward to the lowest point, the plane of the limit slide bar 309 will contact the inner wall of the gear rod 307, thereby limiting the rebound of the U-shaped pressure frame 301, thereby preventing the equipment from loosening its connection due to insufficient internal spring pressure after long-term operation.

[0044] The connection method of the photovoltaic connector includes the following steps:

[0045] S1: Before using the present invention, the outer rubber skin of one end of the output wire 108 is peeled off, the copper core is retained, and the copper core is inserted into the device through the feeding square tube 103;

[0046] S2: When the copper core of the output wire 108 goes deeper and contacts the outer wall of the pressure slide 208, the thrust of the output wire 108 drives the support rod 209 to move inward through the pressure slide 208, so that the support rod 209 loses the restriction on the control rotating plate 210;

[0047] S3: The mechanical power accumulated by the push spring 201 will force the extrusion plate 203 to break through the limit of the control rotating plate 210 and move downward. The bottom of the extrusion plate 203 presses the copper core of the output wire 108, causing the copper core of the output wire 108 to be compressed and deformed.

[0048] A specific application of this embodiment is: the present invention utilizes the fact that photovoltaic cables are mostly copper wires and copper materials are easily deformed, and a push spring 201 is arranged inside the device. Before using the device, the outer rubber skin of one end of the output wire 108 is peeled off to retain the copper core, and penetrate into the device through the feeding square tube 103. When the copper core of the output wire 108 penetrates deeper and contacts the outer wall of the pressure slide 208, the thrust of the output wire 108 will drive the support rod 209 to move inward through the pressure slide 208, so that the support rod 209 loses the restriction on the control rotating plate 210. At this time, the mechanical power accumulated by the push spring 201 will force the extrusion plate 203 to break through the restriction of the control rotating plate 210 and move downward, and the bottom of the extrusion plate 203 presses the output wire 108. The copper core of the output wire 108 is compressed and deformed, and fits on the surface of the power board 106. Through the application of the above components, the device can be applied to cables of various specifications, and the shape of the copper core inside the output wire 108 is changed to form a barb shape inside the device to avoid loosening of the interface due to thermal expansion and contraction. Taking advantage of the fact that the output wire 108 is wrapped with a layer of rubber skin, a clamping blade 206 is arranged inside the device. When the extrusion plate 203 moves downward, it will drive the L-shaped plate 204 to contact the rotating bracket 205, forcing the rotating bracket 205 to rotate downward with the connection point as the center, so that the clamping blade 206 is closely attached to the outer wall of the output wire 108. At this time, due to the inclined design of the clamping blade 206, the cutting edge of the clamping blade 206 is squeezed. When the output wire 108 is pressed down, the rubber skin of the output wire 108 is depressed. When the output wire 108 generates tension outside, the clamping blade 206 is affected by its own inclination and will increase the clamping force on the output wire 108, so as to avoid the device shaking with the wind due to the strong wind in the application environment, causing the connection position of the wire and the connector to become loose. By utilizing the characteristic that the rotating bracket 205 moves downward during operation, a U-shaped pressure frame 301 is arranged inside the device. When the rotating bracket 205 moves downward, it will push the U-shaped pressure frame 301 to move downward and force the corresponding end of the prying rod 306 to move downward. The prying rod 306 is restricted by the fixed frame 305, and will force the other end to drive the sliding rod 303 to lift upward, so that the pushing rod 302 squeezes the output wire upward. The output wire 108 is clamped and restricted to the outer end of the output wire 108, so as to avoid the wire skin rupture of the clamping position of the clamping blade 206 due to long-term wear during the long-term operation of the equipment, thereby affecting the connection stability of the equipment. The push rod 302 is used to move upward to extrude the output wire 108, and a pressurized air bag 304 is arranged inside the equipment. When the push rod 302 extrude the output wire 108, the output wire 108 will synchronously extrude the pressurized air bag 304. At this time, the pressurized air bag 304 will deform to block the feeding port of the feeding square tube 103, thereby improving the sealing performance of the equipment. While avoiding the weathering and embrittlement of the wire skin, a buffer space is provided for the connection position between the equipment and the output wire 108, thereby avoiding the wire skin rupture due to multiple bending at the terminal.In addition, when the U-shaped pressure frame 301 moves downward, the limit slide bar 309 moves along the inner wall of the limit block 308, and when the U-shaped pressure frame 301 moves downward to the lowest point, the plane of the limit slide bar 309 will contact the inner wall of the gear rod 307, limiting the rebound of the U-shaped pressure frame 301, and preventing the device from loosening due to insufficient internal spring pressure after long-term operation.
