Description

Technical Field

[0001] This invention relates to the field of photovoltaic connector technology, and in particular to a quick-connect connector for photovoltaic applications. Background Technology

[0002] In photovoltaic power generation systems, connectors serve as critical interfaces and typically contain fuses to protect the circuit. When a fuse fails due to overload, it must be replaced promptly to restore system functionality.

[0003] However, traditional replacement methods pose serious safety hazards in outdoor, humid, rainy, snowy, or underwater environments. When the connector housing is disassembled, conductive components such as terminals and fuses are directly exposed to the external environment. Moisture can easily penetrate the terminal contact area, and long-term operation can lead to corrosion and oxidation of the conductor terminals and deterioration of insulation performance, thereby causing short circuit faults. Summary of the Invention

[0004] Therefore, it is necessary to provide a quick-connect connector for photovoltaic applications to address the problem of moisture intrusion into the terminal contact area during current fuse replacement processes, which can cause short circuits.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A quick-connect connector for photovoltaic applications, comprising:

[0007] The main housing has a protective channel extending along its own central axis, and the side wall of the main housing is provided with an installation port;

[0008] A protective shell, which is coaxially and detachably connected to the main housing, is used to fix the cable when the cable enters the protective channel;

[0009] A replaceable component, comprising a fuse and a mounting sleeve, wherein the fuse is detachably disposed inside the mounting sleeve; after the mounting sleeve enters the protection channel through the mounting port, the fuse is electrically connected to the cable.

[0010] Furthermore, it also includes an electrical connection unit and a driving source. The electrical connection unit includes a first connecting piece, a second connecting piece, a connecting cylinder, a slide rod, and an elastic reset unit. The connecting cylinder is coaxially disposed on the outside of the cable, and the slide rod is fixedly connected to the connecting cylinder. The first connecting piece and the second connecting piece are coaxially disposed on the outside of the fuse, and the first connecting piece and the second connecting piece are symmetrically disposed along the radial direction of the cable. Both the first connecting piece and the second connecting piece are slidably connected to the slide rod. The elastic reset unit is used to make the first connecting piece and the second connecting piece slide towards each other along the radial direction of the cable. The driving source is used to drive the first connecting piece and the second connecting piece to slide in a direction away from or towards each other along the radial direction of the cable.

[0011] Furthermore, the drive source includes an adjustment knob and a cam transmission assembly, the adjustment knob being movably connected to the sheath; when the adjustment knob is rotated, the cam transmission assembly drives the first connecting piece and the second connecting piece to slide along the radial direction of the cable in a direction that moves away from or closer to each other.

[0012] Furthermore, the cam transmission assembly includes a transmission gear, a turntable, and a slider unit. The transmission gear is fixedly connected to the adjustment knob. The turntable is coaxially disposed inside the sheath housing and is rotatably connected to the connecting cylinder. The turntable can rotate around the central axis of the cable. One side of the turntable is provided with multiple short tooth structures, which are circumferentially arranged around the central axis of the turntable. The transmission gear meshes with the short tooth structures. When the turntable rotates around the central axis of the cable, the slider unit drives the first connecting piece and the second connecting piece to slide radially away from or towards each other along the cable.

[0013] Furthermore, the slider unit includes a first slider and a second slider, which are symmetrically arranged along the radial direction of the cable. The first slider is slidably disposed inside the first connecting piece, and the second slider is slidably disposed inside the second connecting piece. Both the first and second connecting pieces are provided with key blocks, and both the first and second sliders are provided with keyways. The key blocks and keyways are slidably connected. The key blocks cooperate with the keyways to restrict the rotation of the first and second sliders around the central axis of the cable. Both the first and second sliders are provided with protruding structures, and a vortex track is provided on the other side of the turntable. The protruding structures are slidably connected to the vortex track, and the vortex track is used to convert the rotational motion of the turntable into linear motion of the first and second sliders along the radial direction of the cable.

[0014] Furthermore, the replaceable component also includes a heat dissipation unit for reducing the temperature of the fuse.

[0015] Furthermore, the heat dissipation unit includes multiple heat dissipation pipes, each of which is disposed inside the mounting sleeve. Each heat dissipation pipe extends radially along the cable, and the interior of each heat dissipation pipe is in communication with the external environment.

[0016] Furthermore, it also includes a buffer unit, which is used to reduce the tension when the cable is subjected to tension along its own axial direction.

[0017] Furthermore, the buffer unit includes a spring and a rotating plate, the rotating plate being rotatably connected to the turntable, one end of the spring being connected to the inner wall of the protective shell, and the other end of the spring being connected to the rotating plate.

[0018] Furthermore, it also includes a limiting housing, which is rotatably connected to the main housing; the limiting housing is used to limit the displacement of the mounting sleeve in the radial direction of the cable.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a quick-connect connector for photovoltaic applications, comprising: a main housing, a sheath, and a replaceable component. The main housing has a protective channel extending along its central axis, and a mounting port is provided on the side wall of the main housing. The sheath is coaxially and detachably connected to the main housing, used to secure the cable when it enters the protective channel. The replaceable component includes a fuse and a mounting sleeve. The fuse is detachably disposed inside the mounting sleeve, and when the mounting sleeve enters the protective channel through the mounting port, the fuse is electrically connected to the cable. Therefore, by replacing the fuse and mounting sleeve as a whole, the fuse replacement operation is not only more convenient, but the replacement process is also ensured to be conducted in a sealed environment, effectively preventing moisture intrusion and avoiding short-circuit faults.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] The following reference Figures 1 to 12 This invention describes a quick-connect connector for photovoltaic applications provided in an embodiment of the present invention.

[0043] like Figure 1 and Figure 2 As shown, the quick-connect photovoltaic connector provided in this embodiment is particularly suitable for power transmission in photovoltaic power generation systems. Specifically, the quick-connect photovoltaic connector includes a main housing 100, a sheath 112, and a locking nut 503. Both ends of the main housing 100 are detachably coaxially connected to the sheath 112, and the locking nut 503 is rotatably connected to the sheath 112. Furthermore, a waterproof ring 504 is provided between the locking nut 503 and the sheath 112, and the waterproof ring 504 is coaxially positioned on the outside of the cable 201.

[0044] Furthermore, the quick-connect connector for photovoltaic applications also includes replaceable components. These replaceable components include a fuse 211 and a mounting sleeve 210, with the fuse 211 detachably disposed inside the mounting sleeve 210. The main housing 100 has a protective channel extending along its central axis, and a mounting opening 102 is provided on the side wall of the main housing 100, communicating with the protective channel. The mounting sleeve 210 can slide into the protective channel radially along the cable 201 through the mounting opening 102.

[0045] Furthermore, the photovoltaic quick-connect connector also includes a limiting housing 110, which is rotatably connected to the main housing 100 to limit the displacement of the mounting sleeve 210 in the radial direction of the cable 201.

[0046] Specifically, during connector installation, the operator first pushes the fuse 211 into the mounting sleeve 210 along the axial direction of the cable 201. Additionally, a notch 111 is provided on the limiting housing 110. Rotating the limiting housing 110 aligns the notch 111 with the mounting opening 102. At this point, the mounting sleeve 210 is pushed into the protective channel along the radial direction of the cable 201 through the notch 111 and mounting opening 102. Next, rotating the limiting housing 110 misaligns the notch 111 with the mounting opening 102, thus locking the radial displacement of the mounting sleeve 210. Subsequently, when the mounting sleeve 210 and fuse 211 enter the protective channel, both ends of the fuse 211 are electrically connected to the cable 201 within the protective channel. Finally, the locking nut 503 rotates around the axial direction of the cable 201, linking with the protective sleeve 112 to further secure the cable 201 and prevent it from shaking. Meanwhile, the waterproof ring 504 located between the locking nut 503 and the sheath 112 is subjected to the squeezing force of the locking nut 503, thereby further tightening the cable 201 and the sheath 112 to prevent water from entering the connector.

[0047] Specifically, the mounting opening 102 on the main housing 100 is provided with wing plates 101 along both the upper and lower ends, i.e. Figure 12 In the vertical direction. Specifically, when the mounting sleeve 210 is pushed to slide through the mounting port 102, the upper and lower circumferential surfaces of the mounting sleeve 210 are in contact with the surface of the wing plate 101. Therefore, the wing plate 101 ensures that the mounting sleeve 210 maintains a sealed fit with the main housing 100 during the sliding replacement process.

[0048] When fuse 211 needs to be replaced, rotate the limiting housing 110 to align the notch 111 with the mounting port 102. Use a mounting sleeve 210 with a new fuse 211 already in place to push the old mounting sleeve 210 out of the main housing 100 along the radial direction of the cable 201. This allows for fuse 211 replacement in a completely sealed environment without disassembling any fasteners, effectively preventing external moisture from entering the conductor connection. The continuous sealing fit of the wing plate 101 structure ensures reliable waterproofing inside the connector even during replacement operations.

[0049] In one embodiment, the photovoltaic quick-connect connector further includes an electrical connection unit 300 and a driving source 400. The electrical connection unit 300 includes a first connecting piece 311, a second connecting piece 312, a connecting cylinder 302, a slide rod 301, and an elastic reset unit. The connecting cylinder 302 is coaxially arranged with the cable 201, and the slide rod 301 is fixedly connected to the connecting cylinder 302. The first connecting piece 311 and the second connecting piece 312 are symmetrically arranged along the radial direction of the cable 201, and both the first connecting piece 311 and the second connecting piece 312 are slidably connected to the slide rod 301, allowing them to slide along the radial direction of the cable 201. The elastic reset unit is used to make the first connecting piece 311 and the second connecting piece 312 slide closer to each other along the radial direction of the cable 201. The driving source 400 is used to drive the first connecting piece 311 and the second connecting piece 312 to slide either away from or closer to each other along the radial direction of the cable 201. In addition, a conductor terminal 303 is fixedly provided at the end of the connecting cylinder 302 away from the cable 201. The conductor terminal 303 is used to connect and fix the conductor in the cable 201 to ensure the stability of power transmission.

[0050] Furthermore, the elastic reset unit includes a first spring plate 321 and a second spring plate 322. One end of the first spring plate 321 is hinged to the slide rod 301, and the other end abuts against the first connecting piece 311. One end of the second spring plate 322 is hinged to the slide rod 301, and the other end abuts against the second connecting piece 312. The elastic force of the first spring plate 321 always causes the first connecting piece 311 to tend to move closer to the fuse 211, and the elastic force of the second spring plate 322 always causes the second connecting piece 312 to tend to move closer to the fuse 211.

[0051] In one embodiment, the drive source 400 includes an adjustment knob 401 and a cam drive assembly, wherein the adjustment knob 401 is movably connected to the sheath housing 112. When the adjustment knob 401 is rotated, the cam drive assembly causes the first connecting piece 311 and the second connecting piece 312 to move away from or towards each other in the radial direction of the cable 201.

[0052] In one embodiment, the cam drive assembly includes a drive gear 425, a turntable 410, and a slider unit. The drive gear 425 is fixedly connected to an adjustment knob 401. The turntable 410 is coaxially disposed inside the sheath 112 and is rotatably connected to the connecting cylinder 302. The turntable 410 is capable of rotating around the central axis of the cable 201. Multiple short tooth structures 411 are provided on one side of the turntable 410, arranged circumferentially around the central axis of the turntable 410. The drive gear 425 meshes with the short tooth structures 411. The adjustment knob 401 drives the drive gear 425 to rotate, which in turn drives the turntable 410 to rotate via the short tooth structures 411. The slider unit drives the first connecting piece 311 and the second connecting piece 312 to slide radially along the cable 201 in directions that are either moving away from or close to each other.

[0053] In one embodiment, the slider unit includes a first slider 421 and a second slider 422, which are symmetrically arranged along the radial direction of the cable 201. The first slider 421 is slidably disposed inside the first connecting piece 311, and the second slider 422 is slidably disposed inside the second connecting piece 312. Both the first connecting piece 311 and the second connecting piece 312 are provided with key blocks 313, and both the first slider 421 and the second slider 422 are provided with keyways 424. The key blocks 313 and keyways 424 are slidably connected. The key blocks 313 and keyways 424 cooperate to restrict the rotation of the first slider 421 and the second slider 422 around the central axis of the cable 201. Furthermore, both the first slider 421 and the second slider 422 are provided with protruding structures 423, and a vortex track 412 is provided on the other side of the turntable 410. The protruding structures 423 and the vortex track 412 are slidably engaged.

[0054] Specifically, when fuse 211 needs to be replaced, the operator turns the adjustment knob 401, which drives the transmission gear 425 to rotate. The transmission gear 425, through meshing with the short tooth structure 411, drives the turntable 410 to rotate around the central axis of the cable 201. Due to the spline engagement between the key block 313 and the keyway 424, the rotation of the first slider 421 and the second slider 422 around the central axis of the cable 201 is restricted; at the same time, the protruding structure 423 slides into contact with the vortex track 412, thereby driving the first slider 421 and the second slider 422 to slide and separate along the radial direction of the cable 201, thereby driving the first connecting piece 311 and the second connecting piece 312 to slide and separate synchronously along the radial direction of the cable 201, so that the first spring piece 321 and the second spring piece 322 rotate around the radial direction of the cable 201 in a direction away from each other, thereby overcoming the elastic force of the first spring piece 321 and the second spring piece 322, releasing the clamping of the fuse 211, and facilitating the replacement operation.

[0055] Understandably, to achieve power transmission to the fuse 211, simply rotating the adjustment knob 401 in the opposite direction will cause the first connecting piece 311 and the second connecting piece 312 to slide in opposite directions along the radial direction of the cable 201, gradually approaching and clamping the fuse 211. At this time, the first connecting piece 311 and the second connecting piece 312 are connected to the connecting cylinder 302, and the electrical connection between the conductor in the cable 201 and the fuse 211 is completed through the conductor terminal 303.

[0056] In one embodiment, the replaceable component further includes a heat dissipation unit for reducing the temperature of the fuse 211. Further, the heat dissipation unit includes multiple heat dissipation pipes 212, each disposed within the mounting sleeve 210, extending radially along the cable 201, and the interior of each heat dissipation pipe 212 communicating with the external environment.

[0057] Specifically, when the fuse 211 is working, the heat it generates is conducted to the wall of the heat dissipation pipe 212, and the air flow in the heat dissipation pipe 212 carries away a large amount of heat, thereby achieving the heat dissipation effect of the fuse 211.

[0058] Furthermore, since the connection between the conductor terminal 303 and the conductor is relatively strong, the connection between the conductor terminal 303 and the conductor is prone to breakage when the cable 201 is subjected to tension along its own axial direction.

[0059] In one embodiment, the photovoltaic quick-connect connector further includes a buffer unit. When the cable 201 is subjected to tension along its own axial direction, the buffer unit absorbs and disperses the impact energy to prevent the cable 201 from breaking. Further, the buffer unit includes a spring 501 and a rotating plate 502, the rotating plate 502 being rotatably connected to the turntable 410, one end of the spring 501 being connected to the rotating plate 502, and the other end being connected to the inner wall of the sheath 112.

[0060] Specifically, when the cable 201 connected to one end of the fuse 211 is subjected to axial tension, the tension passes through the conductor terminal 303 on the same side as the cable 201, causing the connecting cylinder 302 and the slide rod 301 to move together in the direction of the tension. Since the first spring piece 321 abuts against the first connecting piece 311, the first connecting piece 311 is in contact with the first slider 421; simultaneously, the second spring piece 322 abuts against the second connecting piece 312, the second connecting piece 312 is in close contact with the second slider 422; and the first slider 421 and the second slider 422 are connected to the turntable 410. Therefore, the movement of the connecting cylinder 302 and the slide rod 301 drives the first connecting piece 311 and the second connecting piece 312 to move, which in turn drives the first slider 421 and the second slider 422 to move synchronously, ultimately pushing the turntable 410 to move synchronously and compress the spring 501. This causes the spring 501 to undergo elastic deformation, generating a buffering effect, thereby absorbing and dispersing the impact energy and maintaining a continuous and stable connection between the conductor terminal 303 and the conductor.

[0061] Furthermore, the sheath 112 is equipped with a sealing slide plate 402 that can slide along the axial direction of the cable 201, and the adjusting knob 401 abuts against the sealing slide plate 402. Therefore, the movement of the turntable 410 causes the adjusting knob 401 and the sealing slide plate 402 to move synchronously in the direction of tension. This not only ensures that all components move synchronously along the central axis of the cable 201 without jamming during the buffering process, but also ensures that the sealing slide plate 402 and the adjusting knob 401 are always in contact, maintaining a good sealing effect.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the 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 modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
