[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments. The present invention covers any substitution, modification, equivalent method and scheme made within the spirit and scope of the present invention.

[0018] In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without these detailed descriptions.

[0019] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the accompanying drawings are all simplified and not in exact proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0020] In large-scale industrial equipment, there are generally multiple cabinets involved in the daily operation. Taking the energy storage system as an example, there are DC cabinets, battery cabinets, high-voltage control cabinets and other cabinets. These cabinets usually need to be connected to each other with power supply harnesses, communication harnesses, etc. in order to carry out corresponding work.

[0021] Please refer to Figure 1 , shows a schematic diagram of a multi-cabinet interconnection harness provided by an embodiment of the utility model, including multiple main harnesses 10 and multiple adapter harnesses 20, each main harness 10 correspondingly connected to a cabinet, each adapter harness 20 is detachably connected to the main harnesses 10 of two adjacent cabinets, wherein the main harness 10 includes a first harness 11 and a second harness 12, the first harness 11 can be horizontally laid at the bottom of the cabinet during installation, and its two ends are detachably connected to the adapter harness 20, and the second harness 12 can be vertically laid during installation, one end of which is connected to the first harness 11, and the other end is used to connect to the corresponding cabinet. By splitting the harnesses interconnecting multiple cabinets into multiple main harnesses, two adjacent main harnesses are detachably connected through adapter harnesses, so that installation can be simpler, and if the main harness of one mechanism fails, only the failed main harness needs to be replaced, without replacing the harnesses of all cabinets, saving costs.

[0022] Specifically, the first wiring harness 11 of the main wiring harness 10 is connected to the first connector 111 and the second connector 112 at both ends, and the adapter wiring harness 20 includes a third wiring harness 21, and the third wiring harness 21 is connected to the third connector 211 and the fourth connector 212 at both ends, respectively. The first connector 111 and the fourth connector 212 can be adapted and plugged, and the second connector 112 and the third connector 211 can be adapted and plugged, thereby realizing the quick disconnection between the adapter wiring harness 20 and the two adjacent main wiring harnesses 10.

[0023] Specifically, the connectors on the first wiring harness 11 and the third wiring harness 21 can be the same type. For example, in this embodiment, the first connector 111 and the second connector 112 are adapted female connectors and male connectors, and the third connector and the fourth connector respectively use the same female connector and male connector, which are convenient to manufacture and do not need to be distinguished. In other embodiments, the first connector 111 and the second connector 112 on the first wiring harness 11 are both female connectors, while the third connector 211 and the fourth connector 212 of the third wiring harness 21 are both male connectors, so that there is no need to distinguish the direction during installation, which increases convenience.

[0024] Specifically, the second wiring harness 12 includes multiple sub-wiring harnesses 13. Each cabinet is equipped with multiple electronic devices that need to be powered or communicate. Multiple sub-wiring harnesses 13 extend from the second wiring harness 12 and are used to connect to the electronic devices on the cabinet. The end of each sub-wiring harness can be connected to a different connector (not shown in the figure) to correspond to the wiring ports of different electronic devices.

[0025] At the installation site of the equipment, the distances between the cabinets may be inconsistent. If adapter harnesses of different lengths are made according to different cabinet spacings, it will affect the production and installation efficiency. The adapter harness 20 provided by the utility model has a uniform and fixed length, can be mass-produced, improves efficiency, and does not need to be distinguished during installation. By setting an adjustment component 22, the length of the adapter harness 20 is adjusted according to the location of the installation site to adapt to different cabinet spacings. The adjustment component 22 includes a threading mechanism and a limiting mechanism, wherein the threading mechanism includes a first threading hole and a second threading hole, and the third wire harness 21 passes through the first threading hole and the second threading hole respectively. The limiting mechanism is connected to the threading mechanism to limit the position of the third wire harness 21 in the first threading hole and the second threading hole, thereby adjusting the length.

[0026] Please refer to Figure 2 , is a schematic diagram of an adjustment component provided by an embodiment of the utility model. Figure 2 As shown, the threading mechanism includes an "8"-shaped body 221, a first threading hole 222 and a second threading hole 223 are parallel to each other and penetrate the "8"-shaped body 221, and the third wire harness 21 extends from the first end of the "8"-shaped body 221 into the first threading hole 222, and extends from the second end of the "8"-shaped body 221 into the second threading hole 223, and then extends from the first end of the "8"-shaped body 221, wherein the overlong portion of the third wire harness 21 is left at the second end of the "8"-shaped body 221, thereby adjusting the length of the third wire harness 21. After the length of the third wire harness 21 is adjusted, the position can be fixed by a limiting mechanism. Figure 2As shown, the limiting mechanism includes two fasteners 224, and the fastener 224 is provided with a third wire passing hole and an external threaded portion (not shown in the figure). One end of the first wire passing hole 222 and the second wire passing hole 223 is provided with an internal thread. The third wire harness 21 first passes through the third wire passing hole, and then passes through the first wire passing hole 222 and the second wire passing hole 223 in sequence. The external threaded portion of the fastener 224 is configured to be squeezed and shrunk. After the length of the third wire harness 21 is adjusted, the two fasteners 224 are threadedly connected to the first wire passing hole 222 and the second wire passing hole 223, respectively, so that the external threaded portion of the fastener 224 shrinks the wire harness in the compression hole to limit the position.

The limiting mechanism includes two extrusion plates 228 and two compression springs 229. Two mounting holes are provided on the square plate 225. The two mounting holes are respectively intersected with the first wire passing hole 226 and the second wire passing hole 227 at right angles. The two compression springs 229 are respectively located in the two mounting holes, wherein one end of the compression spring 229 is located in the mounting hole, and the other part protrudes away from the mounting hole and is connected to one side of the extrusion plate 228. The two extrusion plates 228 are respectively located in the first wire passing hole 226 and the second wire passing hole 227, and the other side of the extrusion plate 228 abuts against the third wire harness 21 in the hole, so that the compression force of the compression spring 229 is used to press the third wire harness 21 to limit it.
