[0019] When the winding disk rotates, the elastic strip is squeezed and contracts, and at this time, the elastic strip loses engagement with the engaging gear.

[0020] The present invention has the following beneficial effects:

[0021] 1. The wiring harness terminal installation mechanism of the photovoltaic grid-connected cabinet cooperates with the shift block and the first locking block. When installing or removing the terminal, the shift block is shifted to move the shift block upward, and the first locking block moves upward with the shift block until the end of the first locking block is no longer located in the placement groove. At this time, it is relatively simple to install or remove the terminal; when the terminal is placed in the placement groove, the shift block is released, and the first locking block locks the terminal by its own gravity; the terminal can be installed or removed by shifting the shift block, which is simple to operate and convenient for one-handed operation.

[0022] 2. The wiring harness terminal installation mechanism of the photovoltaic grid-connected cabinet, through the cooperation of the unlocking rod, the rotating block, the driving rack and the driving gear, enables the operator to pull the unlocking rod and the first engaging block at the same time, so that the end of the first engaging block is no longer located in the placement groove. When installing the terminal, the terminal is inserted into the placement groove, and the driving rack is meshed with the driving gear through the cooperation of the pushing block and the passive block, and the rotating block is driven to rotate, so that the blanking port is located on the bottom side of the first engaging block. At the same time, through the cooperation of the extrusion rod and the sealing block, the sealing block is resisted during the movement of the extrusion rod, so that the sealing block is away from the annular block, so that air will flow into the piston groove, so that the suction cup loses suction, so that the first engaging block is smoothly reset from the blanking port, and the purpose of locking the terminal is achieved; not only that, when in use, only one unlocking rod needs to be toggled once to unlock multiple terminals, which reduces the steps of multiple operations and improves the unlocking efficiency; not only that, when installing the terminal, it is only necessary to insert the terminal into the placement groove to achieve automatic locking, without the need for additional manual locking steps, and the operation is simple and convenient for one-handed operation.

[0023] 3. The wiring harness terminal installation mechanism of the photovoltaic grid-connected cabinet cooperates with the second tooth segment, the extension block and the rotating gear. When the terminal is removed, the extension block moves upward, and in the process of moving, the second tooth segment and the rotating gear cooperate to make the rotating gear drive the winding disk to rotate together, thereby realizing automatic release of the wire and reducing the steps of manual operation. In addition, sufficient wires can be reserved to reduce accidental injuries caused by pulling the wires during the disassembly process;

[0024] At the same time, through the cooperation of the elastic strip and the engaging gear, when the winding drum stops moving, the winding drum will not rotate at will due to the limitation of the elastic strip. At the same time, through the setting of the elastic strip, the unnecessary rotation of the winding drum after the rotation is completed is reduced, thereby improving the accuracy of controlling the length of the wire pay-out and take-up, and improving the accuracy of the operation.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: This embodiment is intended to promote the solution of the problem that the wiring harness terminals are usually pre-installed on the guide rails. Since the photovoltaic grid-connected cabinet requires a large number of connected wires, the use of the wiring harness terminals is also corresponding. It is inevitable that several terminals will be installed side by side on a guide rail. When one of the wiring harness terminals is damaged and needs to be repaired or replaced, the surrounding wiring harness terminals need to be taken out together, which makes the repair too troublesome. Please refer to Figure 1-Figure 9 A wiring harness terminal installation mechanism for a photovoltaic grid-connected cabinet includes a fixed shell 110, a plurality of placement grooves 111 for placing terminal bodies are opened inside the fixed shell 110, a first locking block 112 and a second locking block 113 for locking the terminal bodies are movably installed inside the fixed shell 110, an unlocking rod 114 for uniformly unlocking the terminal bodies is movably installed inside the fixed shell 110, a rotating block 115 for individually unlocking the terminal bodies is rotatably installed on the surface of the unlocking rod 114, and a driving structure 120 for rotating the rotating block 115 is installed inside the fixed shell 110.

[0037] See Figure 8 In a specific implementation, the driving structure 120 includes a driving gear 121 installed on the side of the rotating block 115, a driving rack 122 movably installed inside the fixed shell 110, and a blanking port 123 opened on the rotating block 115. When the driving gear 121 is engaged with the driving rack 122, the driving gear 121 drives the rotating block 115 to flip, so that the position of the blanking port 123 changes, causing the second engaging block 113 to fall from the blanking port 123.

[0038] A pushing groove 130 is provided on the inner wall of the placement groove 111, and the second locking block 113 is movably inserted and slid inside the pushing groove 130. A first spring 131 is provided between the pushing groove 130 and the second locking block 113. A pulling groove 132 is provided on the inner wall of the fixed shell 110, and the pulling groove 132 is communicated with the placement groove 111. The first locking block 112 is movably arranged inside the pulling groove 132.

[0039] A groove 133 is formed on the surface of the fixed housing 110 , a shift block 134 is installed on the front side of the first engaging block 112 , and the shift block 134 is movably placed inside the groove 133 . A plurality of partition plates 135 for independently installing the terminal body are installed inside the placement groove 111 .

[0040] See Figure 1 and Figure 2 In a specific implementation, the partition plate 135 can be set to install several terminals separately when installing the terminal body. At the same time, the partition plate 135 can arrange the terminals in an orderly manner, avoiding confusion and misalignment as much as possible, and can be quickly positioned during installation and removal, thereby improving the efficiency of installation and removal;

[0041] Through the setting of the first locking block 112, when installing and removing the terminal, the operator only needs to move the locking block 134, and the locking block 134 drives the first locking block 112 to move upward, so that the end of the first locking block 112 is no longer located inside the placement groove 111, thereby achieving the effect of convenient installation and removal of the terminal body. When the terminal body is installed and placed inside the placement groove 111, it is only necessary to loosen the locking block 134, and the first locking block 112 locks the terminal by descending under its own gravity.

[0042] In this embodiment: through the cooperation between the shift block 134 and the first locking block 112, when installing or removing the terminal, the shift block 134 is shifted to make the shift block 134 move up, and at the same time, the first locking block 112 follows the shift block 134 to move up until the end of the first locking block 112 is away from the placement groove 111. At this time, whether installing or removing the terminal is relatively simple; at the same time, when the terminal is placed inside the placement groove 111, the shift block 134 is released, and the first locking block 112 locks the terminal by descending by its own gravity; the terminal can be installed or removed by shifting the shift block 134, which is simple to operate and convenient for one-handed operation.

[0043] Embodiment 2: This embodiment is intended to solve the problem that when installing a large number of terminals in a grid-connected cabinet, the operator needs to manually move the dial block 134 one by one, which is troublesome to operate. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 9 A projection groove 140 is provided on the fixed shell 110, and a projection block 141 is installed on the first engaging block 112. The projection block 141 is inserted and matched inside the projection groove 140. Through the cooperation of the projection block 141, when the operator takes out any terminal alone, he only needs to lift the projection block 141 to lift the first engaging block 112, thereby losing the lock on the terminal. A piston groove 142 is provided on the surface of the fixed shell 110, and a piston block 143 is installed inside the piston groove 142. A T-block 144 is installed on the side of the projection block 141, and one end of the T-block 144 is connected to the piston block 143. A suction cup 145 is installed on the bottom side of the piston groove 142, and the suction cup 145 is connected to the inside of the piston groove 142; when the first engaging block 112 moves up, the T-block 144 drives the piston block 143 to move up, so that the suction cup 145 generates suction to adsorb the first engaging block 112.

[0044] See Figure 2 , Figure 3 and Figure 4In the specific implementation, when it is necessary to install terminals in large quantities, the unlocking rod 114 is lifted up, so that the unlocking rod 114 drives the first engaging block 112 to move up. At the same time, the T-block 144 is used to drive the piston block 143 to move up during the movement of the first engaging block 112, so that the suction cup 145 generates suction. As the first engaging block 112 continues to move upward, the suction cup 145 adsorbs and fixes the first engaging block 112. At this time, the end of the first engaging block 112 is no longer located in the placement groove 111. At the same time, the operator places the unlocking rod 114 at the highest point of the pulling groove 132, so that the unlocking rod 114 is stationary.

[0045] An extrusion groove 150 and a movable groove 151 are provided inside the fixed housing 110. A push block 220 is slidably installed inside the extrusion groove 150. A first protrusion 152 is integrally installed on the surface of the push block 220. A second spring 153 is installed between the extrusion groove 150 and the first protrusion 152. A passive block 160 is movably installed inside the movable groove 151. A second protrusion 161 is installed on the surface of the passive block 160. A third spring 162 is installed between the second protrusion 161 and the movable groove 151. The driving rack 122 is installed on the side of the passive block 160.

[0046] See Figure 2 , Figure 3 and Figure 4 In a specific implementation, when installing the terminal, the terminal is inserted into the placement groove 111. During the process of inserting the terminal into the placement groove 111, the upper side of the terminal resists the pushing block, causing the pushing block 220 to move upward, and during the upward movement, the pushing block 220 squeezes the passive block 160, causing the passive block 160 to move. During the movement, the driving rack 122 is driven to engage with the driving gear 121, so that the driving gear 121 drives the rotating block 115 to rotate, and the blanking port 123 is located on the bottom side of the first locking block 112. It should be noted that the diameter of the blanking port 123 is larger than the diameter of the first locking block 112.

[0047] An extrusion rod 163 is installed on the side of the driving rack 122, an air outlet 164 is opened on the inner wall of the piston groove 142, an annular block 165 is installed inside the air outlet 164, a sealing block 170 is movably installed on the front side of the annular block 165, spring grooves 171 are symmetrically opened on the surface of the annular block 165, a fourth spring 172 is installed inside the spring groove 171, and the fourth spring 172 is connected to the sealing block 170. When the passive block 160 moves, the extrusion rod 163 is inserted into the air outlet 164, and the extrusion rod 163 resists the sealing block 170, and at this time the sealing block 170 and the annular block 165 are clearance-matched.

[0048] See Figure 2 , Figure 3 and Figure 4In a specific implementation, when the driving rack 122 moves, the extrusion rod 163 moves together, and is inserted into the air outlet 164 during the movement, and resists the sealing block 170, so that the sealing block 170 is away from the annular block 165, so that air flows into the piston groove 142, causing the suction cup 145 to lose suction, so that the first locking block 112 is smoothly reset from the blanking port 123, and the terminal is locked.

[0049] For specific implementation, see Figure 4 The fixed housing 110 has an arc groove 180 in its interior, the arc groove 180 communicates with the pulling groove 132, a baffle 181 is installed at the connection between the arc groove 180 and the pulling groove 132, a one-way torsion spring 182 is installed between the baffle 181 and the inside of the pulling groove 132, and a first tooth segment 183 for resetting the rotating block 115 is installed in the arc groove 180, see Fig. 9 A limiting groove 230 is provided on the inner wall of the pulling groove 132, a limiting block 232 is movably installed inside the limiting groove 230, and a limiting spring 231 is installed between the limiting block 232 and the limiting groove 230. The setting of the limiting block 232 is to prompt the operator to place the unlocking rod 114 in a suitable position.

[0050] See Figure 2 , Figure 3 and Figure 4 In the specific implementation, when the terminals are unlocked, the unlocking rod 114 is pushed into the arc groove 180, so that the unlocking rod 114 returns to the starting point by its own weight, and during the resetting process, the driving gear 121 engages with the first tooth segment 183, so that the driving gear 121 rotates while driving the rotating block 115 to rotate, and the blanking port 123 is reset during the rotation process, which is convenient for a new round of unified installation of the terminals.

[0051] In this embodiment: through the cooperation of the unlocking rod 114, the rotating block 115, the driving rack 122 and the driving gear 121, the operator pulls the unlocking rod 114 and pulls the first engaging block 112 at the same time, so that the end of the first engaging block 112 is no longer located in the placement groove 111. When installing the terminal, the terminal is inserted into the placement groove 111. Through the cooperation of the pushing block and the passive block 160, the driving rack 122 is engaged with the driving gear 121, and the rotating block 115 is driven to rotate, so that the blanking port 123 is located at the bottom side of the first engaging block 112. At the same time, through the cooperation of the extrusion rod 163 and the sealing block 170, During the movement of the extrusion rod 163, the sealing block 170 is resisted, so that the sealing block 170 is away from the annular block 165, so that air will flow into the piston groove 142, causing the suction cup 145 to lose suction, so that the first locking block 112 is smoothly reset from the blanking port 123, thereby achieving the purpose of locking the terminal; not only that, when in use, it is only necessary to toggle the unlocking rod 114 once to unlock multiple terminals, reducing the steps of multiple operations and improving the unlocking efficiency; not only that, when installing the terminal, it is only necessary to insert the terminal into the placement groove 111 to achieve automatic locking, without the need for additional manual locking steps, and the operation is simple and convenient for one-handed operation.

[0052] Embodiment 3: This embodiment is intended to facilitate solving the problem that when installing or repairing the terminal, since the terminal surface is equipped with a wire, and the wire is installed inside the grid cabinet through a fixture, when the terminal is removed, it also means that the fixture of the wire is removed, thereby increasing the difficulty of maintenance. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 9 A support platform 184 is symmetrically installed on the fixed shell 110, a connecting shaft 185 is installed between the two support platforms 184, a winding disk 190 for winding up the wire is rotatably installed on the surface of the connecting shaft 185, and a plurality of winding disks 190 are provided. A rotating gear 191 is installed on the side of the winding disk 190, and a second tooth segment 192 is installed on the side of the extending block 141; when the extending block 141 moves, the rotating gear 191 meshes with the second tooth segment 192, so that the winding disk 190 rotates.

[0053] It should be noted that the elastic strip 211 is configured as a metal elastic strip 211 .

[0054] See Figure 2 , Figure 3 ,and Figure 6In a specific implementation, when the terminal is disassembled, the extending block 141 extends during the upward movement of the first engaging block 112, and the second tooth segment 192 is engaged with the rotating gear 191 during the extending process, so that the rotating gear 191 drives the winding disk 190 to rotate during the rotation process, thereby realizing automatic release of the wire and reducing the number of manual operation steps. Moreover, when removing or repairing the terminal, sufficient wire can be reserved, so that the wire can be automatically released when the terminal is disassembled, thereby reducing accidental injuries caused by pulling the wire during the disassembly process.

[0055] A locking gear 210 is installed on the surface of the connecting shaft 185, and an elastic strip 211 is installed on the inner wall of the winding disk 190. The end of the elastic strip 211 is locked with the locking gear 210; when the winding disk 190 rotates, the elastic strip 211 is squeezed and contracted, and at this time the elastic strip 211 loses its engagement with the locking gear 210.

[0056] In a specific implementation, through the cooperation between the elastic strip 211 and the engaging gear 210, when the extending block 141 stops moving, the elastic strip 211 can be engaged inside the engaging gear 210, so that the winding drum 190 stops rotating. When the extending block 141 rises, the winding drum 190 rotates and applies pressure to the elastic strip 211 during the rotation, so that the end of the elastic strip 211 curls up, so that the elastic strip 211 loses the engagement with the engaging gear 210, so that the winding drum 190 rotates smoothly, and the excessive unwinding and unwinding of the winding drum 190 due to the unnecessary rotation is minimized, thereby reducing the unnecessary rotation, improving the accuracy of controlling the unwinding and unwinding length of the wire, and improving the accuracy of the operation.

[0057] In this embodiment: through the cooperation of the second tooth segment 192, the extension block 141 and the rotating gear 191, when the terminal is disassembled, the extension block 141 moves upward, and in the process of moving, the cooperation of the second tooth segment 192 and the rotating gear 191 is utilized, so that the rotating gear 191 drives the winding disk 190 to rotate together, thereby realizing automatic release of the wire, reducing the steps of manual operation, and not only that, sufficient wire can be reserved, reducing accidental injuries caused by pulling the wire during the disassembly process;

[0058] At the same time, through the cooperation between the elastic strip 211 and the engaging gear 210, when the winding drum 190 stops moving, the winding drum 190 will not rotate at will due to the limitation of the elastic strip 211. At the same time, through the setting of the elastic strip 211, the unnecessary rotation of the winding drum 190 after the rotation is completed is reduced, thereby improving the accuracy of controlling the length of the wire release and reeling, and improving the accuracy of the operation.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
