[0021] Refer to the following Figures 1 to 12 A photovoltaic quick-connect connector provided in an embodiment of the present invention is described.

[0022] like Figure 1 and Figure 2 As shown, the photovoltaic quick-connect connector provided in this embodiment is particularly suitable for transmitting electrical energy in photovoltaic power generation systems. Specifically, the photovoltaic quick-connect connector includes a main housing 100, a protective housing 112, and a locking nut 503. Both ends of the main housing 100 are detachably coaxially connected to the protective housing 112, and the locking nut 503 is rotatably connected to the protective housing 112. In addition, a waterproof ring 504 is disposed between the locking nut 503 and the protective housing 112 and is coaxially disposed on the outside of the cable 201.

[0023] Furthermore, the photovoltaic quick-connect connector includes a replaceable component. This replaceable component includes a fuse 211 and a mounting sleeve 210. The fuse 211 is removably mounted within the mounting sleeve 210. The main housing 100 has a protective channel extending along its central axis. A mounting opening 102 is provided on the sidewall of the main housing 100. The mounting opening 102 communicates with the protective channel, allowing the mounting sleeve 210 to slide through the mounting opening 102 in the radial direction of the cable 201 and into the protective channel.

[0024] Furthermore, the photovoltaic quick-connect connector further includes a limiting housing 110 , which is rotatably connected to the main housing 100 and is used to limit the displacement of the mounting sleeve 210 in the radial direction of the cable 201 .

[0025] Specifically, when installing the connector, the operator first pushes the fuse 211 into the installation sleeve 210 along the axial direction of the cable 201. Furthermore, a notch 111 is provided on the limiting housing 110. The limiting housing 110 is rotated so that the notch 111 and the installation opening 102 are aligned. The installation sleeve 210 is then pushed into the protective channel along the radial direction of the cable 201 through the notch 111 and the installation opening 102. Next, the limiting housing 110 is rotated so that the notch 111 and the installation opening 102 are misaligned, thereby locking the radial displacement of the installation sleeve 210. Subsequently, when the installation sleeve 210 and the fuse 211 enter the protective channel, both ends of the fuse 211 are electrically connected to the cable 201 that has entered the protective channel. Finally, the locking nut 503 is rotated around the axial direction of the cable 201, further securing the cable 201 and preventing it from shaking. At the same time, the waterproof ring 504 located between the locking nut 503 and the sheath shell 112 is squeezed by the locking nut 503, thereby further pressing the cable 201 and the sheath shell 112 to prevent water from entering the interior of the connector.

[0026] In particular, the mounting opening 102 on the main housing 100 is provided with wing plates 101 along both upper and lower ends, that is, Figure 12 Specifically, when the mounting sleeve 210 is pushed and slid through the mounting opening 102, the upper and lower circumferential surfaces of the mounting sleeve 210 contact the surfaces of the wing plates 101. Therefore, the provision of the wing plates 101 ensures that the mounting sleeve 210 maintains a sealed fit with the main housing 100 during the sliding replacement process.

[0027] When fuse 211 needs to be replaced, the retaining housing 110 is rotated to align the notch 111 with the installation opening 102. The old installation sleeve 210, now fitted with a new fuse 211, is then pushed radially out of the main housing 100. This allows fuse 211 to be replaced in a completely sealed environment without the need to remove any fastening components, effectively preventing moisture from intruding into the conductor connection. The continuous sealing provided by the wing plate 101 ensures reliable waterproofing within the connector even during replacement.

[0028] 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 sliding rod 301, and an elastic reset unit. The connecting cylinder 302 is coaxially arranged with the cable 201, and the sliding 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 the first connecting piece 311 and the second connecting piece 312 are both slidably connected to the sliding rod 301, and the first connecting piece 311 and the second connecting piece 312 are both able 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 have a sliding tendency to approach 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 along the radial direction of the cable 201 in a direction away from or close to each other. In addition, a conductor terminal 303 is fixedly provided at one end of the connecting tube 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.

[0029] Furthermore, the elastic reset unit includes a first elastic piece 321 and a second elastic piece 322. One end of the first elastic piece 321 is hinged to the slide bar 301, and the other end abuts the first connecting piece 311. One end of the second elastic piece 322 is hinged to the slide bar 301, and the other end abuts the second connecting piece 312. The elastic force of the first elastic piece 321 constantly forces the first connecting piece 311 to move toward the fuse 211, while the elastic force of the second elastic piece 322 constantly forces the second connecting piece 312 to move toward the fuse 211.

[0030] In one embodiment, the drive source 400 includes an adjustment knob 401 and a cam transmission assembly, wherein the adjustment knob 401 is movably connected to the sheath shell 112. When the adjustment knob 401 is rotated, the cam transmission assembly causes the first connecting piece 311 and the second connecting piece 312 to move away from or toward each other in the radial direction of the cable 201.

[0031] In one embodiment, the cam transmission assembly includes a transmission gear 425, a rotating disk 410, and a slider unit. The transmission gear 425 is fixedly connected to the adjustment knob 401. The rotating disk 410 is coaxially disposed within the sheath shell 112 and is coaxially rotatably connected to the connecting cylinder 302. The rotating disk 410 is capable of rotating about the central axis of the cable 201. A plurality of short tooth structures 411 are disposed on one side of the rotating disk 410. The plurality of short tooth structures 411 are circumferentially arranged around the central axis of the rotating disk 410, and the transmission gear 425 engages with the short tooth structures 411. The adjustment knob 401 drives the transmission gear 425 to rotate, and the transmission gear 425 drives the rotating disk 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 a direction away from or toward each other.

[0032] 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 arranged inside the first connecting piece 311, and the second slider 422 is slidably arranged inside the second connecting piece 312. The first connecting piece 311 and the second connecting piece 312 are both provided with a key block 313, and the first slider 421 and the second slider 422 are both provided with a key slot 424. The key block 313 and the key slot 424 are slidably connected. The key block 313 and the key slot 424 cooperate to limit the rotation of the first slider 421 and the second slider 422 about the central axis of the cable 201. In addition, the first slider 421 and the second slider 422 are both provided with a protrusion structure 423. A spiral track 412 is provided on the other side of the turntable 410, and the protrusion structure 423 slidably cooperates with the spiral track 412.

[0033] Specifically, when fuse 211 needs to be replaced, the operator rotates adjustment knob 401, driving transmission gear 425. Transmission gear 425, through engagement with short tooth structure 411, drives turntable 410 to rotate about the central axis of cable 201. The splined engagement between key block 313 and keyway 424 restricts the rotation of first and second sliders 421, 422 about the central axis of cable 201. Simultaneously, the protrusion 423 slidably engages with the spiral track 412, driving first and second sliders 421, 422 to slide and separate in the radial direction of cable 201. This in turn drives first and second connecting pieces 311, 312 to simultaneously slide and separate in the radial direction of cable 201, causing first and second spring pieces 321, 322 to rotate radially away from each other around cable 201. This overcomes the elastic force of first and second spring pieces 321, 322, releasing the grip on fuse 211 and facilitating replacement.

[0034] It is understood that to achieve power transmission to the fuse 211, the adjustment knob 401 can be rotated in the opposite direction, causing the first and second connecting pieces 311, 312 to slide in opposite directions along the radial direction of the cable 201, gradually approaching and clamping the fuse 211. At this point, the first and second connecting pieces 311, 312 are connected to the connecting barrel 302, and the electrical connection between the conductor in the cable 201 and the fuse 211 is completed through the conductor terminal 303.

[0035] In one embodiment, the replaceable assembly further includes a heat dissipation unit for reducing the temperature of the fuse 211. Furthermore, the heat dissipation unit includes a plurality of heat dissipation tubes 212, each of which is disposed within the mounting sleeve 210 and extends radially along the cable 201. The interior of each heat dissipation tube 212 is in communication with the external environment.

[0036] Specifically, when the fuse 211 is working, the heat generated by it is transferred to the wall of the heat dissipation tube 212 , and then a large amount of heat is taken away by the air flowing in the heat dissipation tube 212 , thereby achieving a heat dissipation effect for the fuse 211 .

[0037] In addition, since the connection between the conductor terminal 303 and the conductor is relatively firm, when the cable 201 is subjected to a pulling force along its own axial direction, the connection position between the conductor terminal 303 and the conductor is easily broken.

[0038] In one embodiment, the photovoltaic quick-connect connector further includes a buffer unit. When cable 201 is subjected to axial tension, the buffer unit absorbs and disperses the impact energy, preventing cable 201 from breaking. Furthermore, the buffer unit includes a spring 501 and a rotating plate 502. The rotating plate 502 is rotatably connected to the rotating disk 410. One end of the spring 501 is connected to the rotating plate 502, and the other end is connected to the inner wall of the sheath shell 112.

[0039] 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, driving the connecting cylinder 302 and the slide rod 301 to move in the direction of the tension. Because the first elastic piece 321 abuts the first connecting piece 311, the first connecting piece 311 is in contact with the first slider 421. Simultaneously, the second elastic piece 322 abuts the second connecting piece 312, causing the second connecting piece 312 to be in contact with the second slider 422. The first and second sliders 421 and 422 are connected to the rotary disk 410. Therefore, the movement of the connecting cylinder 302 and the slide rod 301 drives the first and second connecting pieces 311 and 312 to move, which in turn drives the first and second sliders 421 and 422 to move synchronously. Ultimately, this pushes the rotary disk 410 to move synchronously, compressing the spring 501. This causes the spring 501 to elastically deform, creating a buffering effect, thereby absorbing and dissipating impact energy and maintaining a continuous and stable connection between the conductor terminal 303 and the conductor.

[0040] Furthermore, the sheath housing 112 is provided with a sealing slide 402 that can slide axially along the cable 201, and the adjustment knob 401 abuts against the sealing slide 402. Therefore, the movement of the rotary disk 410 drives the adjustment knob 401 and the sealing slide 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 402 and the adjustment knob 401 always abut, maintaining a good sealing effect.

[0041] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0042] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
