Technical Field

[0001] This utility model relates to the field of control harness technology, specifically to a control harness for an intelligent logistics cabinet with quick-connect terminals. Background Technology

[0002] IoT-based smart logistics cabinets are devices that can identify, temporarily store, monitor, and manage items. They meet the current development needs of the logistics industry, solve the urgent problem of the last mile of logistics delivery, and control the overall equipment that provides services to a certain load source group, such as relay lines, switching devices, and control systems. Existing technologies often suffer from factors such as friction and wear of logistics equipment, interference from motor signals, and moisture erosion, which render the wiring harness unusable and prevent quick connection of terminals. Additionally, some terminal connections are not secure. To address these issues, we propose a smart logistics cabinet control wiring harness with quick-connect terminals. Utility Model Content

The front end of a connecting ring is fixedly connected to the mounting plate, and the front end of the mounting plate is rotatably connected to the rotating plate. The front end of the rotating plate has four arc-shaped grooves, and the inner side of the arc-shaped grooves is slidably connected to the sliding connecting post. The front end of the sliding connecting post is fixedly connected to the movable insert, and the rear end of the sliding connecting post is fixedly connected to the rectangular slider. The inner side of the rear end of the connecting ring has a rectangular limiting groove, and the inner side of the rectangular limiting groove is slidably connected to the rectangular slider. An anti-slip ring is provided on the outer side of the rotating plate.

[0005] The connecting ring serves as the core carrier to fix the wire harness assembly and terminal assembly. The mounting plate and the rotating plate form a rotating mechanism. Four movable plugs are linked with the arc groove through the sliding connecting column. The rectangular slider slides in the limiting groove. The rotating anti-slip ring drives the rotating plate to rotate. The rotational motion is converted into the radial extension and retraction of the movable plugs through the arc groove. The four-way synchronous extension and retraction plug structure realizes blind insertion operation. The rectangular slider limiting design prevents movement deviation.

[0006] Furthermore, the first terminal assembly also includes a connecting post, a circular groove, a contact post, and a limiting groove.

[0016] 2. This intelligent logistics cabinet control harness with quick-connect terminals enables blind-plug connection of high-voltage, high-current terminals. A single-handed rotating anti-slip ring drives an arc-shaped groove mechanism, allowing four sets of movable plugs to precisely extend and retract radially along rectangular limiting grooves, completing the mechanical engagement and release of the plug interface. While establishing a high-current path through the contact post or contact groove, the nested rubber sealing ring and circular seal form a double waterproof barrier under compression.

[0028] The second terminal assembly 5 includes a terminal housing 51, a rectangular groove 52, a circular seal 53, and a slot 54. The terminal housing 51 is fixedly connected to the front end of another connecting ring 1.

The front end of the terminal housing 51 is fixedly connected to the circular seal 53, which is slidably connected to the sealing ring mounting groove 413.

[0030] The second terminal assembly 5 includes a circular groove 55, a limiting slide bar 56, a circular post 57, and a contact groove 58. A circular groove 55 is provided in the middle of the front end of the terminal housing 51. A limiting slide bar 56 is provided on the inner side of the circular groove 55.

The column and groove structure of the intelligent logistics cabinet control harness enables high current transmission, and the contact resistance can be reduced by the silver-plated contact surface.

[0032] The working principle of the intelligent logistics cabinet control harness with quick-connect terminals provided by this utility model is as follows: When it is necessary to connect the control harness modules of two intelligent logistics cabinets, the operator first rotates the anti-slip ring 48 of the first terminal assembly 4, causing the rotating disk 42 to rotate relative to the mounting disk 41. During the rotation, the arc groove 43 at the front end of the rotating disk 42 pushes the sliding connecting post 44 to move along its trajectory, causing the four movable plugs 45 to retract radially synchronously. At the same time, the rectangular slider 47 slides and guides within the rectangular limiting groove 46, aligning the connecting post 49 of the first terminal assembly of the intelligent logistics cabinet control harness with the circular groove 55 at the front end of the terminal housing 51 of the second terminal assembly of the intelligent logistics cabinet control harness and inserting it. This ensures that the limiting groove 414 on the outside of the connecting post 49 is aligned with the limiting strip 56 on the inside of the circular groove 55 and slides together. At this time, the rubber sealing ring 412 of the first terminal assembly will engage with the second terminal assembly. The circular seal 53 of the component forms a tight seal. The anti-slip ring 48 is rotated in the opposite direction. The arc groove 43 drives the sliding connecting post 44 to drive the movable plug 45 to extend radially in sync, insert and lock into the corresponding slot 54 in the terminal housing 51, and complete the mechanical connection. At the same time, the contact post 411 in the circular groove 410 inside the first terminal component connecting post 49 will insert and tightly contact the contact groove 58 inside the circular post 57 of the second terminal component to achieve electrical conduction. The high-purity oxygen-free copper wire 36 inside the wire harness assembly 3 is connected to the contact post 411 and the contact groove 58 through the layered structure of sponge rubber 35, etc., to transmit current. Its external aramid fiber braided wear-resistant layer 31, ceramicized silicone rubber flame-retardant layer 32, metallized fiber shielding layer 33 and silicone rubber insulation layer 34 provide protection. When disassembling the intelligent logistics cabinet control wire harness, it is only necessary to rotate the anti-slip ring 48 to retract the movable plug 45 to separate the two terminal components.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
