Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of circuit connection mechanisms, specifically a circuit connection mechanism for solar cell modules. Background Technology
[0002] The wiring connection mechanism for solar cell modules is a specially designed device used to safely and reliably conduct the electrical energy generated by the solar cell modules to the external circuit through components such as junction boxes, relay terminals, cables, and bipolar connectors, ensuring smooth current transmission and facilitating system assembly and maintenance.
[0003] The utility model with announcement number CN215527882U discloses a wiring connection device for lithium batteries. This utility model first inserts the wire harness into the inside of the connector, rotates the rotating ring, and under the action of the rotating ring, the locking block completes the function of fastening the wire harness. At this time, the sliding ring fits into the mounting groove, achieving a good sealing effect, thereby solving the problem of safety hazards in the existing connection between lithium batteries and wiring proposed in the prior art.
[0004] In the above-mentioned device, the fastening force of the wire harness is provided by the pressure applied by the sliding ring pushing the locking block. However, since the sliding ring itself does not have the ability to prevent loosening, it is very likely that the sliding ring will loosen during use, resulting in a significant reduction or disappearance of the pressure applied to the end of the wire harness. At this time, the wire harness connection will be loose, which may lead to poor contact and pose certain safety hazards. Therefore, in order to solve the above problems, a wiring connection mechanism for solar cell modules is proposed. Utility Model Content
[0005] The technical problem this utility model aims to solve is to provide a wiring connection mechanism for solar cell modules. This wiring connection mechanism transmits electrical energy through the plug-in connection of a connector and a socket. To improve the connection's firmness, pressure is applied to the elastic pressure block through the threaded connection between the detachable cover and the mounting base, thereby applying pressure to the connector to ensure a tight connection with the socket. The elastic pressure block and elastic sealing ring can accumulate elastic potential energy under pressure. When the external force is removed, they can push the detachable cover upwards to engage with the threads of the mounting base, improving the detachable cover's resistance to loosening. Furthermore, the anti-loosening fasteners can clamp the detachable cover on both sides, preventing it from moving upwards and becoming loose. This solves the technical problem in comparative technologies where the anti-loosening performance at the connection point is poor, easily leading to loose connections and poor contact during use, and posing certain safety hazards.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] A wiring connection mechanism for a solar cell module includes a mounting base mounted on the cell module and an internal connector. A transmission line has a connector at its end, which is plugged into the connector. An elastic block is fixed to the outside of the transmission line, with an elastic sealing ring fitted on it. A removable cover is fitted over the elastic block, with its bottom threaded to the mounting base. Additionally, an anti-loosening fastener is installed on the mounting base. This fastener locks onto both sides of the removable cover after it is tightened, preventing it from moving upwards. Pressure is applied to the elastic block through the threaded connection between the removable cover and the mounting base, thereby applying pressure to the connector to ensure a tight connection between it and the connector. The elastic block and the elastic sealing ring accumulate elastic potential energy under pressure. When the external force is removed, they push the removable cover upwards, causing it to engage with the threads of the mounting base, improving the removable cover's resistance to loosening. Furthermore, the anti-loosening fastener locks onto both sides of the removable cover, preventing it from moving upwards and becoming loose.
[0008] In one possible implementation, the anti-loosening fastener includes a rotating base ring on which two symmetrically arranged elastic pressure rods are fixedly mounted. The ends of the elastic pressure rods are machined into hooks, and the rotating base ring is provided with buckles corresponding to the hooks. After the detachable cover is tightened, the elastic pressure rods are pressed to press against both sides of the detachable cover, and the hooks are engaged in the buckles. At this time, the elastic pressure rods can continuously apply downward pressure to the detachable cover to prevent it from loosening and moving upward.
[0009] In one possible implementation, the anti-loosening fastener further includes a limiting ring fixedly mounted on the mounting base, with an annular limiting groove on its outer side. The rotating base ring is movably engaged in the limiting groove. This structure ensures that the rotating base ring will not separate from the mounting base and can transmit force while also allowing free rotation. This allows the user to adjust the orientation of the elastic pressure rod by rotating the rotating base ring, ensuring that it can always apply pressure to the detachable pressure cap.
[0010] In one possible implementation, the upper surface of the elastic sealing ring is machined with several annular interlocking grooves, and the removable gland is fixedly provided with several interlocking protrusions corresponding to the interlocking grooves. The above structure can improve the tightness of the connection between the removable gland and the elastic sealing ring, and while improving the waterproof performance, it can also constrain the elastic sealing ring from producing significant deformation, so as to facilitate the accumulation of more elastic potential energy and exert a stronger anti-loosening ability.
[0011] In one possible implementation, the detachable cover includes two symmetrical half-cover shells with mating cylinders fixedly mounted on them. The half-cover shells are fixedly connected as one unit by connecting bolts, and the connecting bolts pass through the mating cylinders. The above structure can realize the detachable connection between the detachable cover and the transmission line, and can be easily replaced at any time after the detachable cover is damaged.
[0012] In one possible implementation, the bottom end of the half-cover is fixedly provided with an outward protruding foot, and the upper end face is provided with a groove that matches the size of the elastic pressure rod. The outward protruding foot serves as the force application point of the elastic pressure rod on the detachable cover, while the groove ensures the stability of the connection between the elastic pressure rod and the outward protruding foot, making it less prone to slippage.
[0013] In one possible implementation, the joint of the half-shell is provided with a longitudinally arranged groove, and a sealing strip is fixedly installed in the groove. The above structure can enhance the sealing performance of the joint of the half-shell, thereby improving the overall waterproof effect of the connecting mechanism.
[0014] In summary, this utility model has the following beneficial technical effects:
[0015] The line connection mechanism transmits electrical energy through the plug-in connection between the plug and the socket. To improve the connection strength, pressure can be applied to the elastic pressure block through the threaded connection between the detachable cover and the mounting base, thereby applying pressure to the plug to ensure a tight connection between it and the socket.
[0016] Among them, the elastic pressure block and the elastic sealing ring can accumulate elastic potential energy when compressed. When the external force is removed, they can push the detachable cover upward to make it threadedly engage with the mounting base, thereby improving the detachable cover's resistance to loosening. In addition, the anti-loosening fasteners can hold the detachable cover on both sides, making it unable to move upward and difficult to loosen. Attached Figure Description

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0024] like Figure 1 - Figure 2 As shown in the figure, this embodiment provides a wiring connection mechanism for a solar cell module, including a mounting base 1, which is mounted on the battery module and has a connector 2 inside. A transmission line 3 has a plug connector 4 at its end, which is plugged into the connector 2. An elastic pressure block 5 is fixedly mounted on the outside of the transmission line 3, and an elastic sealing ring 7 is fitted on it. A removable pressure cover 6 is fitted over the elastic pressure block 5, and its bottom end is threaded to the mounting base 1. In addition, an anti-loosening fastener 8 is installed on the mounting base 1, which can lock the removable pressure cover 6 in place after it is tightened. This prevents the removable cover 6 from moving upwards. The threaded connection between the removable cover 6 and the mounting base 1 applies pressure to the elastic block 5, which in turn applies pressure to the connector 4 to ensure a tight connection between it and the connector 2. The elastic block 5 and the elastic sealing ring 7 can accumulate elastic potential energy when under pressure. When the external force is removed, they can push the removable cover 6 upwards to engage with the threaded connection between it and the mounting base 1, thus improving the anti-loosening ability of the removable cover 6. In addition, the anti-loosening fastener 8 can hold the two sides of the removable cover 6 in place, preventing it from moving upwards and making it difficult to loosen.
[0025] like Figure 3 As shown, the anti-loosening fastener 8 includes a rotating base ring 81 on which two symmetrically arranged elastic pressure rods 82 are fixedly mounted. The ends of the elastic pressure rods 82 are machined into hooks 83, and the rotating base ring 81 is provided with buckles 84 corresponding to the hooks 83. After the removable cover 6 is tightened, the elastic pressure rods 82 are pressed to press against both sides of the removable cover 6, and the hooks 83 are engaged in the buckles 84. At this time, the elastic pressure rods 82 can continuously apply downward pressure to the removable cover 6 to prevent it from loosening and moving upward. In addition, the anti-loosening fastener 8 also includes a limiting ring 85 fixedly mounted on the mounting base 1. A circular limiting groove is opened on its outer side. The rotating base ring 81 is movably engaged in the limiting groove. The above structure ensures that the rotating base ring 81 will not separate from the mounting base 1 and can transmit force, while also allowing it to rotate freely. This allows the user to adjust the orientation of the elastic pressure rods 82 by rotating the rotating base ring 81 to ensure that it can always apply pressure to the removable cover 6.
[0026] like Figure 2 As shown, the upper surface of the elastic sealing ring 7 is machined with several annular interlocking grooves, and the removable pressure cap 6 is fixedly provided with several interlocking protrusions corresponding to the interlocking grooves. The above structure can improve the tightness of the connection between the removable pressure cap 6 and the elastic sealing ring 7. While improving the waterproof performance, it can also restrain the elastic sealing ring 7 from significant deformation, so as to accumulate more elastic potential energy and exert a stronger anti-loosening ability.
[0027] like Figure 4 As shown, the detachable cover 6 includes two symmetrical half-cover shells 61, on which a mating cylinder 62 is fixedly mounted. The half-cover shells 61 are fixedly connected as one unit by connecting bolts 63, and the connecting bolts 63 pass through the mating cylinder 62. This structure enables the detachable connection between the detachable cover 6 and the transmission line 3, facilitating easy replacement of the detachable cover 6 if it is damaged. To facilitate the use of the anti-loosening fastener 8, an outwardly protruding foot 64 is fixedly mounted at the bottom of the half-cover shell 61, and a [missing information - likely a type of fastener] is provided on its upper surface. The groove 65 matches the size of the elastic pressure rod 82. The protruding foot 64 serves as the force application point of the elastic pressure rod 82 on the detachable pressure cover 6, while the groove 65 ensures the stability of the overlap between the elastic pressure rod 82 and the protruding foot 64, preventing slippage. In addition, a longitudinally arranged groove is provided at the splice of the half cover 61, and a sealing strip 66 is fixedly installed in the groove. The above structure can enhance the sealing performance at the splice of the half cover 61, thereby improving the overall waterproof effect of the connection mechanism.
[0028] The working principle and usage process of this utility model:
[0029] The line connection mechanism transmits electrical energy through the plug-in connection between the plug 4 and the socket 2. In order to improve the connection, pressure can be applied to the elastic pressure block 5 through the threaded connection between the detachable pressure cover 6 and the mounting base 1, thereby applying pressure to the plug 4 to ensure that it is tightly connected to the socket 2 and prevent the connection from loosening.
[0030] Among them, the elastic pressure block 5 and the elastic sealing ring 7 can accumulate elastic potential energy when they are compressed. When the external force is removed, they can push the detachable pressure cover 6 upward so that it engages with the mounting base 1 through the thread, thereby improving the anti-loosening ability of the detachable pressure cover 6.
[0031] In addition, the anti-loosening fastener 8 can press down on both sides of the removable cover 6, preventing it from moving upwards and loosening. Specifically, after the removable cover 6 is tightened, pressing the elastic pressure rod 82 presses it against both sides of the removable cover 6, causing the hook 83 to engage with the buckle 84. At this time, the elastic pressure rod 82 can continuously apply downward pressure to the removable cover 6, preventing it from loosening and moving upwards. In addition, the anti-loosening fastener 8 also includes a limiting ring 85 fixedly installed on the mounting base 1, with an annular limiting groove on its outer side. The rotating base ring 81 is movably engaged in the limiting groove. The above structure ensures that the rotating base ring 81 will not separate from the mounting base 1 and can transmit force, while also allowing it to rotate freely. This allows the user to adjust the orientation of the elastic pressure rod 82 by rotating the rotating base ring 81, ensuring that it can always apply pressure to the removable cover 6.
[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
