[0002] The male and female terminals of photovoltaic connectors are mostly stamped and rounded structures. A conductive crown spring is assembled inside the female terminal as a conductive transmission medium. When the male terminal is inserted, it contacts and presses the conductive crown spring. After the conductive crown spring contacts the inner wall of the female terminal, current transmission is achieved.

[0003] In the prior art, a professional automatic machine is required to assemble the crown spring inside the female terminal, and the crown spring is prone to missing or damaged. At the same time, the crown spring may be deformed during the process of being pressed into the female terminal by the automatic machine, which may cause the crown spring to shrink or be pulled out when the female terminal is plugged into the male terminal, and may also lead to high contact resistance and temperature rise NG problems.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a photovoltaic connector terminal structure to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a photovoltaic connector terminal structure, comprising a female terminal body, one end of which is fixedly connected to a spring arm, the spring arm is twisted, one end of which is fixedly connected to a circular socket, a plug-in column is plugged into the inside of the spring arm and the circular socket, and one end of the plug-in column is fixedly connected to a male terminal body.

[0008] Furthermore, the ends of the female terminal body and the male terminal body that are away from each other are both fixedly connected with a fixing ring, the outer surface of the fixing ring is provided with a claw, and one end of the fixing ring is fixedly connected with a rivet cup.

[0009] Furthermore, the spring arm is composed of a plurality of mutually spaced recessed spring sheets, and the spring arm is smaller than the diameter of the plug-in column.

[0010] Furthermore, a shielding tube is threadedly connected to the outer surface of the male terminal body, and the shielding tube is movably connected to the spring arm and the outer surface of the female terminal body. A mounting groove is provided on the outer surface of the shielding tube, and a heat dissipation groove is provided at the bottom of the inner wall of the mounting groove.

[0011] Furthermore, a guide strip is fixedly connected between the fixing ring and the outer surface of the female terminal body, and a guide groove is formed on the inner wall of the shielding tube corresponding to the guide strip.

[0013] Furthermore, an anti-slip groove is provided on the outer surface of the rotating ring, and clamping grooves are provided on both inner walls of the rotating groove. Clamping blocks are fixedly connected to the corresponding clamping grooves on both sides of the fixing block.

[0014] Furthermore, outer surfaces of the female terminal body and the male terminal body are fixedly connected to a limiting ring corresponding to the fixing cylinder and the shielding cylinder.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model arranges the female terminal body and the spring arm in an integrated manner, thereby avoiding the subsequent assembly of the spring arm and the female terminal body again. This arrangement prevents the spring arm from being deformed due to greater pressure during production, thereby effectively avoiding the problem of the spring arm being collapsed and pulled out when the female terminal and the male terminal are plugged in, and also avoids the problems of high resistance and temperature rise NG after the male terminal body contacts the female terminal.

[0017] 2. The utility model has a plurality of mutually spaced recessed spring sheets forming a spring arm, so that when the plug-in column is inserted into the interior of the spring arm, the contact area therewith is larger, thereby improving the electrical performance of the female terminal body and the male terminal body after being connected together, and effectively increasing the vibration resistance level of the terminals after assembly.

[0018] 3. The utility model inserts the plug-in column into the spring arm, and the shielding tube can also be directly moved to the outer surface of the spring arm and the female terminal body. Under the shielding of the shielding tube, the spring arm can be prevented from being deformed due to external force during use.

The fixing block is rotated through the rotating ring, and the fixing block limits the shielding cylinder through the rotating groove on the shielding cylinder. At this time, under the limitation of the shielding cylinder, it is not easy for the female terminal body and the male terminal body to become disengaged after being connected.

[0020] Of course, when implementing any product of the present utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model.

[0032] Embodiment 1

[0033] Please refer to Figure 1 As shown, the present utility model is a photovoltaic connector terminal structure, including a female terminal body 1. One end of the female terminal body 1 is fixedly connected with a spring arm 2. The spring arm 2 is twisted. One end of the spring arm 2 is fixedly connected with a circular socket 3. A plug post 4 is inserted into the spring arm 2 and the circular socket 3. One end of the plug post 4 is fixedly connected with a male terminal body 5. The spring arm 2 can be wound around the male terminal body 5.

[0034] The plug post 4 on the male terminal body 5 is directly inserted into the circular socket 3 and the inside of the spring arm 2, so that the plug post 4 contacts the inner wall of the spring arm 2, and at the same time, the male terminal body 5 is also connected to the female terminal body 1.

[0035] By integrally setting the female terminal body 1 and the spring arm 2, it is avoided that the spring arm 2 needs to be assembled with the female terminal body 1 again later. This setting makes the spring arm 2 not deformed due to excessive pressure during production, effectively avoiding problems such as spring arm collapse and being pulled out when the female terminal and the male terminal are inserted, and also avoiding problems such as high resistance and NG temperature rise after the male terminal body 5 contacts the female terminal.

[0036] In one embodiment, for the above-mentioned female terminal body 1, fixing rings 6 are fixedly connected to both ends of the female terminal body 1 and the male terminal body 5 that are far away from each other. Claws 7 are arranged on the outer surface of the fixing rings 6. One end of the fixing rings 6 is fixedly connected with riveting cups 8.

[0037] After the photovoltaic cable is connected to the terminal, the riveting cup 8 can be extruded, so that the connection firmness between the photovoltaic cable and the terminal can be ensured. Through the claws on the fixing ring 6, the corresponding terminal can be firmly connected to the external device.

[0038] In one embodiment, for the above-mentioned spring arm 2, the spring arm 2 is composed of a number of spaced-apart recessed elastic pieces, and the spring arm 2 is smaller in diameter than the insertion post 4.

[0039] The overall shape setting of the spring arm 2 enables the spring arm 2 structure to maximize the contact area with the insertion post 4 when the insertion post 4 moves into the interior of the spring arm 2, thereby improving the electrical performance after the female terminal body 1 and the male terminal body 5 are connected together, and effectively increasing the anti-vibration level after the terminals are assembled.

[0040] Embodiment Two: Based on Embodiment One

[0041] Please refer to Figures 2 - 6 As shown, for the above-mentioned male terminal body 5, a shielding cylinder 9 is threadedly connected to the outer surface of the male terminal body 5. The shielding cylinder 9 is movably connected to the outer surfaces of the spring arm 2 and the female terminal body 1. An installation groove 10 is formed on the outer surface of the shielding cylinder 9, and a heat dissipation groove 11 is formed at the bottom of the inner wall of the installation groove 10.

[0042] By inserting the insertion post 4 into the interior of the spring arm 2, at this time, the shielding cylinder 9 also directly moves to the outer surfaces of the spring arm 2 and the female terminal body 1 under the drive of the male terminal body 5, so that the spring arm 2 will not be deformed due to its own elastic force when the terminals are in use, and at the same time, there will be no leakage at the connection of the two terminals under the shielding of the shielding cylinder 9; a screen can be arranged inside the installation groove 10, and this setting enables the heat generated at the connection when the connected terminals are working to be dissipated from the inside of the shielding cylinder 9 through the heat dissipation groove 11 and the screen, so that there will be no heat accumulation inside the shielding cylinder 9; the setting of the shielding cylinder 9 threadedly connected to the male terminal body 5 makes it more convenient to assemble the terminals subsequently.

[0043] In one embodiment, for the above-mentioned fixing ring 6, a guiding strip 12 is fixedly connected to the outer surface of the fixing ring 6 and the female terminal body 1, and a guiding groove 13 is formed on the inner wall of the shielding cylinder 9 corresponding to the guiding strip 12.

[0044] When the insertion post 4 is inserted into the interior of the spring arm 2, the guiding groove 13 on the shielding cylinder 9 is aligned with the guiding strip 12, so that the guiding groove 13 can be sleeved on the outer surface of the guiding strip 12 when the shielding cylinder 9 moves to the outer surface of the female terminal body 1. This setting enables the shielding cylinder 9 not to rotate randomly on the outer surface of the female terminal body 1 when shielding the spring arm 2.

[0045] In one embodiment, for the above-mentioned female terminal body 1, a fixing cylinder 14 is threadedly connected to the outer surface of the female terminal body 1. The shielding cylinder 9 is movably connected to the fixing cylinder 14. The guiding groove 13 is also provided on the fixing cylinder 14. A rotating groove 15 is formed on the outer surface of the fixing cylinder 14. A fixing block 16 is movably connected inside the rotating groove 15. A rotating ring 17 is fixedly connected to the outer surface of the fixing block 16. A sliding groove 18 is formed on the outer surface of the shielding cylinder 9 corresponding to the fixing block 16. The fixing block 16 is movably connected to the sliding groove 18. The rotating groove 15 extends to the bottom of the inner wall of the sliding groove 18.

[0046] When the plugging post 4 is completely inserted into the inside of the spring arm 2, one end of the shielding cylinder 9 also moves into the inside of the fixing cylinder 14. At the same time, the fixing block 16 also moves into the inside of the rotating groove 15 on the outer surface of the shielding cylinder 9 through the sliding groove 18. Then, the fixing block 16 is rotated through the rotating ring 17, so that the fixing block 16 contacts the inner wall on the other side of the rotating groove 15. At this time, the fixing block 16 can limit the shielding cylinder 9 through the rotating groove 15 on the shielding cylinder 9, so that after the female terminal body 1 is connected to the male terminal body 5, it is not easy to separate under the limitation of the shielding cylinder 9; the setting of the fixing cylinder 14 threadedly connected to the female terminal body 1 makes it convenient to install the fixing cylinder 14 on the outer surface of the female terminal body 1, and the setting of the guiding groove 13 on the fixing cylinder 14 makes it possible to move the fixing cylinder 14 to the outer surface of the female terminal body 1 without being blocked by the guiding strip 12.

[0047] In one embodiment, for the above-mentioned rotating ring 17, anti-slip grooves 19 are formed on the outer surface of the rotating ring 17. Card slots 20 are formed on both inner walls of the rotating groove 15. Clamping blocks 21 are fixedly connected to both sides of the fixing block 16 corresponding to the card slots 20.

[0048] When the plugging post 4 is plugged into the inside of the spring arm 2, the fixing block 16 contacts one side of the inner wall of the rotating groove 15. At the same time, the clamping block 21 on one side of the fixing block is directly clamped into the corresponding card slot 20. At this time, the rotating ring 17 will not drive the fixing block 16 to rotate randomly inside the rotating groove 15, so that the sliding groove 18 can directly sleeve on the outside of the fixing block 16 when the shielding cylinder 9 moves into the fixing cylinder 14. When the shielding cylinder 9 is fixed, the fixing block 16 is rotated under the drive of the rotating ring 17 and contacts the inner wall on the other side of the rotating groove 15. At this time, the clamping block 21 on the other side of the fixing block 16 is directly clamped into the corresponding card slot 20, so that the fixing block 16 will not rotate randomly when limiting the shielding cylinder 9, thus improving the stability of the shielding cylinder 9 when shielding the spring arm 2; the rotating ring 17 can be rotated through the anti-slip grooves 19. The setting of the anti-slip grooves 19 makes it impossible to slip when rotating the rotating ring 17.

[0049] In one embodiment, for the female terminal body 1 , the outer surfaces of the female terminal body 1 and the male terminal body 5 are fixedly connected with a limiting ring 22 corresponding to the fixing cylinder 14 and the shielding cylinder 9 .

[0050] When the fixing cylinder 14 is rotated to the outer surface of the female terminal body 1, the rear end of the fixing cylinder 14 contacts with the corresponding limiting ring 22. When the shielding cylinder 9 is rotated to the outer surface of the male terminal body 5, the rear end of the shielding cylinder 9 contacts with the corresponding limiting ring 22. After the two terminals are connected together, the shielding cylinder 9 can be moved to the inside of the fixing cylinder 14, so that the fixing cylinder 14 and the shielding cylinder 9 will not fall off when the terminals are working.

[0051] Through the above technical scheme, 1. By setting the female terminal body 1 and the spring arm 2 as an integral unit, it is avoided that the spring arm 2 and the female terminal body 1 are assembled together again later. This setting prevents the spring arm 2 from being deformed due to high pressure during production, thereby effectively avoiding the problem of spring arm collapse and pulling out when the female terminal and the male terminal are plugged in, and also avoids the problems of high resistance and temperature rise NG after the male terminal body 5 contacts the female terminal; 2. The setting of the spring arm 2 composed of a plurality of mutually spaced recessed spring pieces makes the contact area of ​​the plug-in column 4 larger when it is plugged into the inside of the spring arm 2, thereby improving the electrical performance of the female terminal body 1 and the male terminal body 5 after being connected together, and effectively increasing the vibration resistance level of the terminals after assembly; 3. By inserting the plug-in column 4 into the spring arm 2, the shielding tube 9 can also Directly move to the outer surface of the spring arm 2 and the female terminal body 1. Under the shielding of the shielding tube 9, the spring arm 2 can be prevented from being deformed due to external force during use. At the same time, the setting of the heat dissipation groove 11 prevents the heat generated by the spring arm 2 from accumulating inside the shielding tube 9; 4. The shielding tube 9 will not rotate arbitrarily when it is on the outer surface of the female terminal body 1 through the guide strip 12 and the guide groove 13. At the same time, when the shielding tube 9 is moved to the inside of the fixed tube 14, the fixed block 16 can be located in the rotating groove 15 on the shielding tube 9 with the assistance of the slide groove 18. The fixed block 16 is rotated by the rotating ring 17 and the fixed block 16 is limited by the rotating groove 15 on the shielding tube 9. At this time, under the restriction of the shielding tube 9, the female terminal body 1 is not easy to be separated from the male terminal body 5 after being connected.
