Technical Field

[0001] This utility model relates to the field of photovoltaic connector technology, and in particular to a photovoltaic connector. Background Technology

[0002] With social development and technological progress, environmentally friendly and pure energy has gradually attracted people's attention. Photovoltaics, as an environmentally friendly and inexhaustible new energy source, has been valued by people. Photovoltaic panels are a common device for converting solar energy, and the connectors of photovoltaic panels have high requirements during their use.

[0003] Patent document CN221282466U discloses a photovoltaic connector, including a male connector plug and a female connector plug that matches the male connector plug. An insulating sleeve is engaged inside the male connector plug, and an insertion terminal is fixedly installed inside the insulating sleeve. A sealing gasket is fixedly installed on the outside of the insulating sleeve, and a threaded post is fixedly installed at one end of the sealing gasket. This photovoltaic connector adds a flared rubber post inside the plug. When screwed, the rubber post is squeezed and contracted, thereby increasing the tightness of the contact between the rubber post and the wire. Combined with the internal multi-level waterproof structure, it can improve the sealing performance of the connector end. The method of using a snap-fit ​​and then screwing on a cap to seal instead of the traditional snap-fit ​​structure can squeeze the sealing ring at the plug joint, thereby isolating the gap at the connector joint, which can effectively improve the waterproof and sealing performance of the connector. It is less likely to have water leakage problems during long-term outdoor use, and has higher safety.

[0004] Photovoltaic connectors commonly use threaded installation. When using threaded installation, due to thermal expansion and contraction and external factors, the threads may loosen, affecting the installation stability of the photovoltaic connector. At the same time, water can easily enter through the connection gaps, which can also easily damage the photovoltaic connector. Utility Model Content

[0005] This utility model discloses a photovoltaic connector, which aims to solve the technical problem that the threads may loosen due to thermal expansion and contraction and external factors, thus affecting the installation stability of the photovoltaic connector.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A photovoltaic connector includes a connector socket unit and a connector plug unit:

[0008] The connector socket unit includes a socket housing, a ring is fixedly installed on the outer wall of the socket housing, an elastic sheet is fixedly installed on one side of the ring, a sealing sleeve is fixedly installed on the outer wall of the socket housing, a compression plate is attached to the outer wall of the sealing sleeve, a triangular block is fixedly installed on one end of the elastic sheet, and a connecting cylinder is fixedly installed on the inner wall of the socket housing.

[0009] The connector plug unit includes a plug housing, a threaded cylinder fixedly installed on the outer wall of the plug housing, a connecting rod rotatably installed on the outer wall of the threaded cylinder, a semi-circular plate rotatably installed on one end of the connecting rod, a tension spring fixedly installed on one side of the connecting rod, an elastic band fixedly installed on one end of the semi-circular plate, and a connecting plug fixedly installed on the inner wall of the plug housing.

[0010] In a preferred embodiment, the extrusion plate is fixedly mounted on one side of the elastic sheet, and the triangular block is attached to one side of the semicircular sheet.

[0011] In a preferred embodiment, the sealing sleeve is fitted onto the outer wall of the threaded cylinder, and one end of the tension spring is fixedly mounted on the plug housing.

[0012] In a preferred embodiment, the outer wall of the socket housing is threaded, and the inner wall of the plug housing is threadedly connected to the socket housing.

[0013] In a preferred embodiment, there are two semicircular pieces and two elastic bands, with the two semicircular pieces respectively fixedly installed on both sides of the two elastic bands.

[0014] In a preferred embodiment, the bottom of the triangular block is provided with a slope, and the top of the triangular block is provided with a flat surface.

[0015] As can be seen from the above, the photovoltaic connector provided by this utility model has the following technical effects.

[0016] Firstly, during the installation of the socket housing and plug housing, the threaded sleeve is fitted onto the outer wall of the socket housing. Rotating the threaded sleeve tightens the threads onto the outer wall of the socket housing. During the tightening process, the semicircular piece contacts the inclined surface of the triangular block and gradually pushes the elastic piece to deform. Then, the two semicircular pieces are spread apart, stretching the elastic band. The connecting rod angle changes, lengthening the tension spring. After the semicircular piece passes through the elastic band, the elastic piece returns to its original position, and the triangular block plane restricts the position of the semicircular piece.

[0017] Secondly, after installation, the threaded cylinder will be inserted into the sealing sleeve. The rebound force provided by the elastic band and tension spring will squeeze the elastic sheet, and the sealing sleeve will squeeze the compression plate to improve the sealing performance and prevent water from entering the connection.

[0025] Reference Figures 1-4 A photovoltaic connector includes a connector socket unit 100 and a connector plug unit 200:

[0026] The connector socket unit 100 includes a socket housing 101. A ring 102 is fixedly installed on the outer wall of the socket housing 101. An elastic sheet 103 is fixedly installed on one side of the ring 102. The ring 102 provides an installation position for the elastic sheet 103 and has a hollow design to reduce weight. A sealing sleeve 104 is fixedly installed on the outer wall of the socket housing 101. The sealing sleeve 104 is made of rubber and provides a sealing effect. An extrusion plate 105 is attached to the outer wall of the sealing sleeve 104. The extrusion plate 105 extrudes the sealing sleeve 104 to enhance its sealing performance. A triangular block 106 is fixedly installed on one end of the elastic sheet 103. A connecting cylinder 107 is fixedly installed on the inner wall of the socket housing 101.

[0027] The connector plug unit 200 includes a plug housing 201. A threaded cylinder 202 is fixedly installed on the outer wall of the plug housing 201. The threaded cylinder 202 is both a threaded sleeve and a protective shell for the plug housing 201. A connecting rod 203 is rotatably installed on the outer wall of the threaded cylinder 202. A semi-circular piece 204 is rotatably installed on one end of the connecting rod 203. A tension spring 205 is fixedly installed on one side of the connecting rod 203 to provide a rebound force, causing the semi-circular piece 204 to retract inward. An elastic band 206 is fixedly installed on one end of the semi-circular piece 204. The rebound force of the elastic band 206 allows the semi-circular piece 204 to deform. A connecting plug 207 is fixedly installed on the inner wall of the plug housing 201.

[0028] In this embodiment, the semicircular piece 204 contacts the inclined surface of the triangular block 106 and gradually pushes the elastic piece 103 to deform. Then, the two semicircular pieces 204 are spread apart, stretching the elastic band 206, and the angle of the connecting rod 203 changes, lengthening the tension spring 205. After the semicircular piece 204 passes through the elastic band 206, the elastic piece 103 returns to its original position, and the plane of the triangular block 106 restricts the position of the semicircular piece 204. After installation, the threaded cylinder 202 is inserted into the sealing sleeve 104. The rebound force provided by the elastic band 206 and the tension spring 205 will squeeze the elastic piece 103, and the sealing sleeve 104 will squeeze the compression plate 105 to improve the sealing performance and prevent water from entering the connection.

[0029] In a preferred embodiment, the extrusion plate 105 is fixedly installed on one side of the elastic sheet 103, and the triangular block 106 is attached to one side of the semi-circular sheet 204.

[0030] In this embodiment, the sealing sleeve 104 is compressed by the extrusion plate 105 to improve the sealing performance of the sealing sleeve 104.

[0031] In a preferred embodiment, the sealing sleeve 104 is fitted onto the outer wall of the threaded cylinder 202, and one end of the tension spring 205 is fixedly installed on the plug housing 201.

[0032] In this embodiment, the sealing sleeve 104 is used to seal the gaps at the connection to prevent water from entering the gaps.

[0033] In a preferred embodiment, the outer wall of the socket housing 101 is threaded, and the inner wall of the plug housing 201 is threadedly installed with the socket housing 101.

[0034] In this embodiment, the socket housing 101 and the plug housing 201 are installed quickly and stably using threads.

[0035] In a preferred embodiment, there are two semicircular pieces 204 and two elastic bands 206. The two semicircular pieces 204 are fixedly installed on both sides of the two elastic bands 206 respectively.

[0036] In this embodiment, the elasticity of the elastic band 206 enables the two semicircular pieces 204 to expand and contract.

[0037] In a preferred embodiment, the bottom of the triangular block 106 is provided with a slope, and the top of the triangular block 106 is provided with a flat surface.

[0038] In this embodiment, the inclined surface facilitates the semicircular piece 204 to push away the elastic piece 103, while the flat surface facilitates the position restriction of the semicircular piece 204.

[0039] Working principle: During use, when installing the socket housing 101 and the plug housing 201, the threaded cylinder 202 is fitted onto the outer wall of the socket housing 101. Rotating the threaded cylinder 202 tightens the threads onto the outer wall of the socket housing 101. During the tightening process, the semicircular piece 204 contacts the inclined surface of the triangular block 106 and gradually pushes the elastic piece 103 to deform. Then, the two semicircular pieces 204 are spread apart, stretching the elastic band 206. The angle of the connecting rod 203 changes, lengthening the tension spring 205. After the semicircular piece 204 passes through the elastic band 206, the elastic piece 103 returns to its original position. The plane of the triangular block 106 restricts the position of the semicircular piece 204. After being fully screwed in, the connector 207 is inserted into the connector cylinder 107, completing the photovoltaic connection.

[0040] After installation, the threaded sleeve 202 will be inserted into the sealing sleeve 104. The elastic band 206 and the tension spring 205 will provide a rebound force to squeeze the elastic sheet 103. The sealing sleeve 104 will squeeze the compression plate 105 to improve the sealing performance and prevent water from entering the connection.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
