[0023] Embodiments The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Specific implementation method 1: The utility model provides a technical solution: a photovoltaic cable connection component, including a female connector 1 and a male connector 2. A cable 3 is fixed at the rear end of the male connector 2, and the female connector 1 is inserted inside the male connector 2. The male connector 2 includes an outer insulating shell 21, an outer rotating shell 22 installed on the outer side of the front end of the outer insulating shell 21, and a tail plug 27 installed inside the outer insulating shell 21, and a plastic plug 28 is fixed at the front end of the tail plug 27, and the plastic plug 28 is connected to the cable 3 clamped inside the tail plug 27. A tail plate 26 is installed at the front end of the outer insulating shell 21, and the tail plate 26 is connected to the limit plate 24 through a torsion spring 25, and the limit plate 24 is stuck on the outer insulating shell 21, and a pad 23 is provided between the limit plate 24 and the outer rotating shell 22;
[0025] The tail plate 26 is put on the outside of the outer insulating shell 21, and then the torsion spring 25, the limit plate 24 and the pad 23 are put on the outer insulating shell 21 in sequence, and the rear end of the torsion spring 25 is fixed on the tail plate 26, and the front end of the tail plate 26 is installed on the pad 23. The diameter of the limit plate 24 is smaller than the outer insulating shell 21, so the limit plate 24 is made of two parts spliced together or combined by thermal expansion and contraction, and then the outer rotating shell 22 is screwed to the tail plate 26. After fixing the tail plate 26 with a tool, screw the outer rotating shell 22 to complete the installation.
[0026] The female connector 1 includes a baffle 11 at the rear, a protective ring 14 fixed at the front end of the baffle 11, an outer locking claw 15 fixed inside the protective ring 14, an inner locking claw 12 is arranged inside the outer locking claw 15, and an electrical socket 16 is arranged in the middle of the inner locking claw 12.
[0027] Insert the female connector 1 into the interior of the male connector 2, and ensure that the outer locking claw 15 and the inner locking claw 12 fit tightly with the corresponding parts of the male connector 2; rotate the outer rotating shell 22 to further lock the female connector 1 to ensure a firm connection, verify whether the cable connection is firm, and verify whether the outer locking claw 15 and the male connector 2 form a path to ensure that the electrical connection is correct; perform an electrical test through the power jack 16 to ensure that the cable connection is unobstructed.
[0028] The tail plate 26 mounted on the outer insulating shell 21 is rotatable on the outer insulating shell 21 , and the tail plate 26 is screwed together with the outer rotating shell 22 .
[0029] The installation and disassembly process of the cable connection component is simplified. During installation, the user only needs to insert the female connector 1 into the male connector 2 and then rotate the outer rotating shell 22 to complete the locking. During disassembly, the user only needs to rotate the outer rotating shell 22 in the opposite direction to easily release the female connector 1.
[0030] A bottom ring 281 is provided at the rear end of the plastic plug 28, and the bottom ring 281 is clamped on the tail plug 27. At the same time, the three groups of electric cores inside the cable 3 arranged inside the tail plug 27 are respectively connected to the power ring 1 282, the power ring 2 283 and the power ring 3 284 on the plastic plug 28, and the power ring 1 282, the power ring 2 283 and the power ring 3 284 are provided with an insulating structure to avoid the formation of electric arcs; the bottom ring 281 design at the rear end of the plastic plug 28 enables the plastic plug to be firmly clamped on the tail plug 27. This design not only ensures the stable position of the plastic plug in the tail plug, but also provides the necessary mechanical support to prevent movement or dislocation during the cable connection process.
[0031] The internal core of the cable installed on the connecting female connector 1 is connected to the power-on socket 16, the inner locking claw 12 and the outer locking claw 15 in sequence. After the connecting female connector 1 is inserted into the connecting male connector 2, the outer locking claw 15 forms a passage with the power-on ring 1 282, the power-on ring 2 283 and the inner locking claw 12 form a passage, and the power-on socket 16 and the power-on ring 3 284 form a passage.
[0032] An anti-skid ring 221 is provided on the outer side of the rear end of the outer rotating shell 22, and a slide groove 222 is provided on the inner wall of the outer rotating shell 22. At the same time, a protrusion 13 is provided on the protective ring 14, and the protrusion 13 is slidably inserted in the slide groove 222. The anti-skid ring 221 is provided to facilitate the rotation of the outer rotating shell 22. The anti-skid ring 221 is provided on the outer side of the rear end of the outer rotating shell 22. Its main purpose is to enhance the friction force when the user rotates the outer rotating shell 22 to prevent slipping. This design is particularly useful in a slippery or oily environment. The user can more easily rotate the outer rotating shell 22 to complete the connection or disconnection of the cable. The use of the slide groove 222 and the protrusion 13 provides a positioning and guiding function for the insertion and rotation of the female connector 1 inside the male connector 2; ensure that when the user rotates the outer rotating shell 22, the female connector 1 can move according to a predetermined trajectory to achieve accurate connection; when the outer rotating shell 22 is rotated and locked in a certain position, the interaction between the protrusion 13 and the slide groove 222 increases the stability of the cable connection. This design prevents the female connector 1 from loosening or shifting when subjected to external force or vibration; the user can easily connect or disconnect the cable by rotating the outer rotating shell 22. The sliding of the protrusion 13 in the slide groove 222 makes this process smoother and more efficient.
[0033] The outer locking claw 15 is a claw-shaped structure that is larger in the middle and smaller at both ends, and the outer locking claw 15 is made of elastic copper plate. At the same time, the inner locking claw 12 uses a claw-shaped structure, and the power-on socket 16 opened inside is a round hole structure. During the installation process, the outer locking claw 15 will be squeezed to ensure effective power-on contact. Similarly, the tension of the inner locking claw 12 can effectively clamp the position of the power-on ring 283.
[0034] During installation, the outer locking claw 15 is deformed after being squeezed, and then forms a close contact with the corresponding part of the cable or connector. This contact not only ensures the mechanical stability of the cable, but also ensures effective electrical contact through the conductivity of the copper material;
[0035] The tail plug 27 is made of rubber material, and the end of the tail plug 27 is clamped in the inner cavity of the outer insulating shell 21 by a limiting protrusion.
[0036] A photovoltaic cable connection method comprises the following steps:
[0037] Step 1, preparing a connecting component: preparing a photovoltaic cable connecting component;
[0038] Step 2: Install the cable to the male connector: Pass the cable 3 through the tail plug 27 and the plastic plug 28, and ensure that the internal core of the cable 3 is correctly connected with the power ring 1 282, the power ring 283 and the power ring 3 284 on the plastic plug 28; then pull the assembled tail plug 27, the plastic plug 28 and the cable 3 into the outer insulating shell 21, and shrink the tail plug 27 to clamp the cable 3;
[0039] Step 3, rotating the tail plate and the outer rotating shell: screw the tail plate 26 and the outer rotating shell 22 together to ensure a firm connection;
[0040] Step 4, inserting the female connector into the male connector: align the rear baffle 11 of the female connector 1 with the opening of the male connector 2, and slowly insert the female connector 1 into the male connector 2 until the protrusion 13 on the protective ring 14 slides into the slide groove 222 on the inner wall of the outer rotating shell 22;
[0041] Step 5: Rotate the outer rotating shell to lock the connection: apply a rotational force to the outer rotating shell 22 to rotate it around the cable 3, thereby driving the protrusion 13 to slide in the slide groove 222, and then compressing the outer locking claw 15 inward to form a tight fit with the inner wall of the outer rotating shell 22, thereby completing the locking of the female connector 1 and the male connector 2;
[0042] Step 6, verify the cable connection status: verify whether the cable connection is stable, whether the outer locking claw 15 and the power ring 1 282 form a path, whether the power ring 2 283 and the inner locking claw 12 form a path, and at the same time confirm whether the power socket 16 and the power ring 3 284 form a path, to ensure that the cable connection is correct and the circuit is unobstructed;
[0043] Step 7: Complete the cable connection: After confirming that the cable connection is correct, complete the entire photovoltaic cable connection process.
[0044] Among them, in step six, verifying the cable connection status, further includes the step of using testing equipment to check whether the cable connection has leakage, short circuit or excessive resistance to ensure the safety and reliability of the cable connection. In addition, it also includes the step of applying marks or labels to the cable connection to record detailed information of the cable connection to facilitate subsequent maintenance and repair.
[0045] The cable 3 is passed through the tail plug 27 and the plastic plug core 28, and correctly connected to the power ring, and then pulled into the outer insulating shell and clamped by the tail plug, which ensures the stability of the cable connection. When verifying the cable connection status, the test equipment is used to check whether there is leakage, short circuit or excessive resistance, which greatly improves the safety of the cable connection. The screw connection design of the tail plate 26 and the outer rotating shell 22, as well as the insertion and locking process of the connecting female head 1 and the connecting male head 2, make the entire connection process simple and fast to operate, and improve work efficiency.
[0046] When verifying the cable connection status, not only is the connection checked to be firm, but also the paths between each power ring and the locking claws and jacks are verified to ensure the reliability of the electrical connection. Marking or labeling the cable connection records the detailed information of the cable connection, which facilitates subsequent maintenance and repair and reduces misoperation or repeated work caused by unclear information.
[0047] This method is not limited to specific models or specifications of photovoltaic cables and connecting components. It has strong adaptability and versatility and can be applied to a variety of different scenarios and needs. Stable and reliable cable connections can reduce the occurrence of electrical failures, improve the overall performance and stability of the photovoltaic system, and ensure that the system can operate continuously and efficiently.
