CONTENT OF UTILITY MODEL
[0003] In view of the deficiencies of prior art, the utility model aims at providing a connecting structure for solar controller which is more labor-saving in operation, improves assembly speed and quality.
[0004] To achieve the above object, the utility model provides the following technical scheme: a connecting structure for solar controller, including shell and fixed frame, the shell one end is equipped with the connecting piece of integral connection and rotation connection with fixed frame, the fixed frame inner wall both ends are equipped with rotation axis, the connecting piece is equipped with the rotation groove that matches with rotation axis, the rotation axis is equipped with arc surface and plane symmetrically, one of the arc surface of rotation axis is equipped with lug, the rotation groove is equipped with the limit slot that matches with lug in, the connecting piece one end is equipped with the clamping strip still, the fixed frame is equipped with the baffle that matches with clamping strip in, clamping strip is configured as when connecting piece along the plane direction of rotation axis and fixed frame are mutually close, and form the support point of force when passing through clamping strip and baffle and abutting, again to shell exert force and make rotation axis enter into the rotation groove and form rotation connection, baffle is configured as when shell and fixed frame rotate to horizontal plane, clamping strip and baffle abut each other, limit overturning.
[0005] The utility model further sets up: the height of rotation groove opening is 0.9 times of the diameter of rotation axis.
[0006] The utility model further sets up: the length of rotation axis is between 1 / 2 to 2 / 3 of the diameter.
[0007] The utility model further sets up: the length of clamping strip is between 0.75 times to 0.9 times of the length of baffle.
[0008] The utility model further sets up: the top and bottom of rotation groove opening are equipped with antiskid lines.
[0009] The utility model further sets up: connecting piece is equipped with a plurality of reinforcing ribs between the side away from rotating groove and shell.
[0010] The utility model has the advantages of:
[0011] 1. Through the rotation connection of rotating shaft and rotating groove, cooperating with the card strip and baffle structure, the operator only needs to make the connecting piece close to the fixed frame along the plane direction of the rotating shaft, and exerts force with the card strip and baffle contact as the supporting point, and utilizes the lever principle, so that the rotating shaft can be easily clamped into the rotating groove, the rotation connection is completed, the assembly process is greatly simplified, the assembly time and manpower cost are reduced, the production efficiency is improved, and the advantage is obvious in large-scale production. The arc surface and plane of the symmetrical setting of the rotating shaft and the cooperation of the convex block and the limiting groove ensure the stability of the connecting structure after assembly, on the one hand, effectively prevent accidental loosening or displacement between the connecting piece and the rotating shaft, ensure the relative position stability of each part of the solar controller in long-term use, on the other hand, when the shell and the fixed frame rotate to the horizontal plane, the card strip and the baffle restrict each other and limit the overturning, avoid unnecessary rotation caused by external force or vibration, ensure the stability and safety of the equipment operation, reduce the risk of failure caused by loose connection, improve the overall reliability and service life of the solar controller.
[0012] 2. When the height of the rotating groove opening is less than 0.9 times the diameter of the rotating shaft, the opening is too small to be blocked during installation, which may damage the connecting piece or the fixed frame; when the height of the rotating groove opening is greater than 0.9 times the diameter of the rotating shaft, the opening is too large to limit the rotating shaft in the rotating groove, which may damage the connecting structure during rotation; therefore, the height of the rotating groove opening is set to 0.9 times the diameter of the rotating shaft, so that the rotating shaft has certain precision requirement when inserted into the rotating groove, which can play a good guiding role, so that the rotating shaft can always maintain good cooperation state when rotating in the rotating groove, and the stability of the overall connecting structure is enhanced, so that the solar controller can better cope with various vibration, external force and other situations during use.
[0013] 3. When the length of the rotating shaft is less than 1 / 2 of the diameter, it is too short to cause uneven force transmission when matched with the rotating groove, etc. When the length of the rotating shaft is greater than 2 / 3 of the diameter, it is too long to occupy too much space and increase the material cost. Therefore, the length of the rotating shaft is between 1 / 2 and 2 / 3 of the diameter, and the appropriate length range makes the force distribution relatively uniform during the rotation of the rotating shaft, and does not cause too large cantilever effect and too large local stress. When the length of the clamping strip is less than 0.75 times the length of the baffle, it may not provide sufficient limiting force, so that the shell is turned over and the internal structure and electrical connection are damaged. When the length of the clamping strip is greater than 0.9 times the length of the baffle, it will be in contact with the rotating shaft during the rotation, affecting the use effect. Therefore, the length of the clamping strip is between 0.75 and 0.9 times the length of the baffle, which can provide sufficient contact area and resistance, and has feasibility and convenience in processing and manufacturing, and will not increase the processing difficulty due to too large size difference between the clamping strip and the baffle, and is also beneficial to ensure the processing precision, reduce the manufacturing error, improve the production efficiency and product quality.
[0014] 4. Anti-skid lines are arranged at the top and bottom of the opening of the rotating groove, which can increase the friction between the rotating shaft and the opening of the rotating groove when the rotating shaft is inserted into the rotating groove. During assembly, the rotating shaft can be more stably positioned at the corresponding position and is not easy to slide and deviate due to external force and other factors during operation, which helps the operator to more accurately complete the matching and installation of the rotating shaft and the rotating groove, and improves the success rate and efficiency of assembly. The reinforcing ribs are arranged between the side, away from the rotating groove, of the connecting piece and the shell, which effectively enhances the connection strength between the connecting piece and the shell, can share the external force borne by the connecting piece during use, and improves the rigidity and stability of the whole structure.

[0019] Reference Figs. 1 to 3 The embodiment of the utility model is further explained.
[0020] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0021] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.
[0022] Figs. 1 to 3 The diagram illustrates a connection structure for a solar controller, comprising a housing 1 and a mounting bracket 2. One end of the housing 1 is integrally connected to and rotatably connected to the mounting bracket 2. The mounting bracket 2 has symmetrically arranged rotating shafts 4 at both ends of its inner wall. The connecting member 3 has a rotating groove 5 that matches the rotating shaft 4. The rotating shaft 4 has symmetrically arranged arc-shaped and flat surfaces. One arc-shaped surface of the rotating shaft has a protrusion 6. The rotating groove 5 has a limiting groove 7 that matches the protrusion 6. One end of the connecting member 3 also has a retaining strip 8. The mounting bracket 2 has a baffle 9 that matches the retaining strip 8. Through the rotatable connection of the rotating shaft 4 and the rotating groove 5, and with the retaining strip 8 and baffle 9, the operator only needs to bring the connecting member 3 closer to the mounting bracket 2 along the plane of the rotating shaft 4, using the contact between the retaining strip 8 and the baffle 9 as a support point to apply force. Utilizing the lever principle, the rotating shaft 4 can be easily engaged into the rotating groove 5, completing the rotatable connection. This greatly simplifies the assembly process, reduces assembly time and labor costs, and improves production efficiency, especially showing significant advantages in large-scale production. The symmetrically arranged arc-shaped and flat surfaces of the rotating shaft 4, along with the cooperation between the protrusion 6 and the limiting groove 7, ensure the stability of the connection structure after assembly. On the one hand, this effectively prevents accidental loosening or displacement between the connector 3 and the rotating shaft 4, ensuring the relative position stability of each component of the solar controller during long-term use. On the other hand, when the housing 1 and the fixing frame 2 rotate to the horizontal plane, the locking strip 8 and the baffle 9 abut against each other, restricting the flipping and avoiding unnecessary rotation caused by external forces or vibrations. This ensures the stability and safety of the equipment operation, reduces the risk of failure caused by loose connections, and improves the overall reliability and service life of the solar controller.
[0023] When the height of the opening of the rotating groove 5 is less than 0.9 times the diameter of the rotating shaft 4, the opening is too small and obstructed during installation, which may damage the connector 3 or the fixing bracket 2. When the height of the opening of the rotating groove 5 is greater than 0.9 times the diameter of the rotating shaft 4, the opening is too large and cannot confine the rotating shaft 4 within the rotating groove 5, which may damage the connection structure during rotation. Therefore, the height of the opening of the rotating groove 5 is set to 0.9 times the diameter of the rotating shaft 4. This ensures that the rotating shaft 4 has a certain precision requirement when inserted into the rotating groove 5, which plays a good guiding role. This ensures that the rotating shaft 4 maintains a good fit when rotating within the rotating groove 5, enhances the stability of the overall connection structure, and allows the solar controller to better cope with various vibrations and external forces during use.
[0024] When the height of the opening of the rotating groove 5 is less than 0.9 times the diameter of the rotating shaft 4, the opening is too small and obstructed during installation, which may damage the connector 3 or the fixing bracket 2. When the height of the opening of the rotating groove 5 is greater than 0.9 times the diameter of the rotating shaft 4, the opening is too large and cannot confine the rotating shaft 4 within the rotating groove 5, which may damage the connection structure during rotation. Therefore, the height of the opening of the rotating groove 5 is set to 0.9 times the diameter of the rotating shaft 4. This ensures that the rotating shaft 4 has a certain precision requirement when inserted into the rotating groove 5, which plays a good guiding role. This ensures that the rotating shaft 4 maintains a good fit when rotating within the rotating groove 5, enhances the stability of the overall connection structure, and allows the solar controller to better cope with various vibrations and external forces during use.
[0025] When the length of the rotating shaft 4 is less than 1 / 2 of its diameter, it is too short, which leads to problems such as uneven force transmission when it is in contact with the rotating groove 5, etc. When the length of the rotating shaft 4 is greater than 2 / 3 of its diameter, it is too long and will occupy too much space, increasing material costs. Therefore, the optimal length of the rotating shaft 4 is between 1 / 2 and 2 / 3 of its diameter. The appropriate length range ensures that the force distribution of the rotating shaft 4 is relatively uniform during rotation, and will not cause excessive local stress due to excessive cantilever effect caused by excessive length.
[0026] When the length of the locking strip 8 is less than 0.75 times the length of the baffle 9, it may not provide sufficient limiting force, causing the housing 1 to flip over and damage the internal structure and electrical connections. When the length of the locking strip 8 is greater than 0.9 times the length of the baffle 9, it will collide with the rotating shaft 4 during rotation, affecting the performance. Therefore, the optimal length of the locking strip 8 is between 0.75 and 0.9 times the length of the baffle 9, which provides sufficient contact area and resistance. This design is feasible and convenient in manufacturing, avoiding increased processing difficulty due to excessive size differences between the locking strip 8 and the baffle 9, while also ensuring processing accuracy, reducing manufacturing errors, and improving production efficiency and product quality.
[0027] The top and bottom of the opening of the rotating groove 5 are provided with anti-slip texture. When the rotating shaft 4 is inserted into the rotating groove 5, the anti-slip texture can increase the friction between the rotating shaft 4 and the opening of the rotating groove 5. During the assembly process, the rotating shaft 4 can be more stably positioned in the corresponding position, and it is not easy for it to slide or deviate due to external forces or other factors during operation. This helps the operator to complete the installation of the rotating shaft 4 and the rotating groove 5 more accurately, and improves the success rate and efficiency of assembly.
[0028] The connector 3 is provided with several reinforcing ribs between the side opposite to the rotating groove 5 and the housing 1, which effectively enhances the connection strength between the connector 3 and the housing 1, can share the external force borne by the connector 3 during use, and improve the rigidity and stability of the entire structure.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
