[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] Example 1: Please refer to Figure 1-7The utility model provides a technical solution: a wiring harness assembly for a photovoltaic micro inverter, comprising a housing 1 and a docking component 2, a locking component 3 is slidably provided on the side of the housing 1, a connector 6 is provided on a clamping member 4 connected by sliding to the housing 1, a docking rod 8 is provided on the connector 6, and a cable 10 is provided on the connector 6 for limiting and fixing the position of the connecting connector 6;

[0028] The docking component 2 includes a docking hole 205 corresponding to the docking rod 8. The docking component 2 is provided with a docking pipe 202. The inner diameter of the docking pipe 202 is the same as the outer diameter of the connector 6 for power transmission connection.

[0029] The docking component 2 includes a mounting bracket 201, on which a plurality of sets of fixing members 207 are arranged, the mounting bracket 201 is connected to the docking tube 202, a docking member 204 is arranged in the docking tube 202, a plurality of sets of docking holes 205 are arranged on the docking member 204, a first limiting groove 203 is arranged on the docking tube 202, a docking limiting member 206 is arranged on the docking member 204, the locking component 3 includes a nut 301, the nut 301 is arranged in the shell 1, a bolt 302 is threadedly arranged on the nut 301, a limiting member 304 is sleeved on the bolt 302, a sliding groove 303 is arranged on the shell 1, and the bolt 302 is slidably connected to the inner wall of the sliding groove 303.

[0030] The joint 6 is provided with a plurality of groups of limiting protrusions 7, which correspond one-to-one to the first limiting grooves 203 on the docking tube 202. The joint 6 is provided with a second limiting groove 9, which corresponds one-to-one to the docking limiting member 206. A sliding rod is provided inside the shell 1, and a sliding bracket is provided on the bottom of the clamping member 4. The sliding rod passes through the plurality of sliding brackets.

[0031] This device can effectively improve the limiting and fixing effect of multiple groups of cable structures, thereby avoiding the situation where the cables are entangled with each other and causing confusion. Compared with traditional devices, this device adopts a sliding limit adjustment method, which can facilitate position adjustment according to the size and position of different cables, thereby ensuring the stability of the use of this device.

[0032] When the device is in working state, by installing and fixing the docking component 2, the device can be adaptively adjusted to dock with the docking component 2. The structure of the docking tube 202 and the first limiting groove 203 in the docking component 2 can facilitate the accurate combination of the device, reducing the risk of misaligned docking of the device. Multiple groups of docking holes 205 corresponding to the docking rods 8 can ensure the stability and accuracy of power transmission. The structure of the docking limiter 206 can ensure that the combination direction of the device is unique, avoiding abnormal insertion caused by rotational misalignment.

[0033] When the device is docked, the docking component 2 is in a fixed state, and the joint 6 structure is slidably adjusted above the shell 1 to adapt to the position of the docking component 2. When the joint 6 slides to a suitable position, the clamping effect of the clamping member 4 and the docking joint 6 can be achieved by rotating the threaded rod 5, thereby avoiding mutual shaking between the clamping member 4 and the joint 6. At this time, the limit member 304 slides following the clamping member 4.

[0034] When the joint 6 slides to the appropriate position, the bolt 302 is rotated at this time. Through the threaded clamping effect of the bolt 302 and the nut 301, the limit member 304 can be clamped and fixed, thereby ensuring the position fixing effect of the device. The structure of the buffer pad can still limit and fix the clamping member 4 after the mutual spacing of the clamping members 4 changes, thereby avoiding the clamping member 4 from shaking relative to the limit member 304.

[0035] The stability of power transmission of the device is achieved by inserting the multiple groups of docking rods 8 on the joint 6 into the docking holes 205 in the docking member 204.

[0036] Embodiment 2: Figure 1-7 As shown, a wiring harness assembly for a photovoltaic micro-inverter disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that a buffer pad is provided on the limit member 304, and the limit member 304 contacts the clamping member 4 through the buffer pad, and the clamping member 4 contacts the connector 6. The clamping members 4 are symmetrically distributed on both sides of the connector 6, and a threaded rod 5 is rotatably provided on the clamping member 4 on the other side, and the threaded rod 5 is threadedly connected to the clamping member 4 on the other side.

[0037] The structure of the buffer pad can effectively improve the stability of the clamping effect of the device on the side of the clamping member 4. When the device uses a joint 6 with a smaller diameter, the distance between multiple groups of clamping members 4 is smaller. At this time, the buffer pad can ensure that the limit member 304 limits the clamping member 4, reducing the free shaking of the clamping member 4.
