[0002] As an indispensable component of glass doors such as supermarket display cabinets and freezers, electrically connected door hinges not only bear the heavy responsibility of mechanical connection, but also integrate the conductive function of electrically heated glass, effectively realizing the simultaneous installation of glass door hinges and electrical connections, significantly improving the convenience of installation and overall aesthetics, while ensuring safety of use. However, this type of door hinge faces structural design challenges in pursuing waterproof performance to avoid electrical short circuits. Traditional waterproof designs often focus on enhancing the sealing after assembly, which inevitably leads to structural complexity, not only increasing manufacturing costs, but also significantly reducing assembly efficiency and convenience, bringing unnecessary difficulties to on-site installation. In addition, the complex structure also increases the difficulty and cost of subsequent maintenance, which is not conducive to the popularization and application of the product. Therefore, the development of an electrically connected door hinge assembly that can maintain high waterproof performance while simplifying the structural design and facilitating assembly and installation has become a technical problem to be solved in the current industry, with significant market demand and broad application prospects.

[0018] In order to better understand the present invention, Figures 1 to 6 The embodiments of the present invention will be explained in detail.

[0019] It should be noted that the directions “front, back, left, right, up, down” mentioned in the text are all based on Figure 1The directions of “front, back, left, right, up and down” are used as the reference.

[0020] See also Figures 1 to 6 The utility model is an electrical connection door shaft that is easy to assemble, comprising an outer shell 1 and an inner shell 2. The outer shell 1 is provided with a docking groove 3 with openings at both ends, and one end of the inner shell 2 is provided with an insertion end adapted to the docking groove 3. The insertion end of the inner shell 2 is provided with a placement groove 21, and a first terminal housing 4 is provided in the placement groove 21. One end of the docking groove 3 is successively inserted with a second terminal housing 5 and an inner shell 2, and limiting slide grooves 6 are provided on both sides of the docking groove 3. Limiting sliders 7 adapted to the limiting slide grooves 6 are provided on both sides of the second terminal housing 5, and female terminals 8 and sub-terminals 9 are respectively inserted in the first terminal housing 4 and the second terminal housing 5; a hollow door shaft 10 connected to the placement groove 21 is provided at the bottom of the inner shell 2, and a plurality of mounting holes 11 are provided on the top of the outer shell 1; a sealing member is provided between the first terminal housing 4 and the second terminal housing 5.

[0021] The outer shell 1 and the inner shell 2 are fixed together by a locking portion, specifically, a latch 13. Both the outer shell 1 and the inner shell 2 are provided with a through-hole 14 that matches the latch 13, and the first terminal housing 4 is provided with an avoidance groove 15 so that the latch 13 will not interfere with the housing when passing through. A threaded end 16 is provided at one end of the latch 13 to prevent it from falling off after being fully inserted. In addition, the outer shell 1 is also provided with a protruding end 17 and a card slot 18. The threaded end 16 of the latch 13 is screwed with a card plate 19 that matches the card slot 18. When the latch 13 is inserted into place, the latch 13 is rotated by pinching the threaded end 16, so that the card plate 19 is stuck in the card slot 18, thereby achieving a secure locking of the outer shell 1 and the inner shell 2.

[0022] In order to enhance the waterproof performance, the sealing member is preferably a rubber ring 12. The thickness of the rubber ring 12 is designed to be less than or equal to the shell wall thickness of the first terminal housing 4 to ensure that an effective sealing layer is formed on the contact surface between the two to prevent moisture penetration.

[0023] In order to improve the convenience of installation, these mounting holes 11 are preferably countersunk holes, and the countersunk ends are located below the top of the inner shell 2 so that there will be no conflict with the inner shell 2 when installing the screws, while maintaining a neat and beautiful appearance.

[0024] In addition, guide blocks 20 adapted to the limiting slide grooves 6 are provided on both sides of the inner shell 2. These guide blocks 20 play a guiding role during the assembly process, so that the inner shell 2 can be smoothly and accurately inserted into the docking groove 3, further improving the efficiency and accuracy of assembly.

[0025] When assembling the electrical connection door shaft: first, plug the female terminal 8 into the sub-terminal 9, and put a rubber ring 12 on the outer shell 1 of the female terminal 8. Then, the first terminal housing 4 is sleeved on the female terminal 8, and the second terminal housing 5 is sleeved on the sub-terminal 9, and the rubber ring 12 is clamped at the same time. Next, pass the wires of the female terminal 8 through the placement groove 21 into the hollow door shaft 10, and pull the wires to make the first terminal housing 4 snap into the placement groove 21 of the inner shell 2. Next, align the insertion end of the inner shell 2 with the docking groove 3 so that the inner shell 2 is completely docked with the outer shell 1. Finally, insert the pin 13 into the through hole 14, and rotate the pin 13 by pinching the threaded end 16 so that the card plate 19 is snapped into the card groove 18, thereby achieving a firm locking of the outer shell 1 and the inner shell 2. It should be noted that during the installation stage of the electrical connection door shaft, the mounting screws need to be inserted into the countersunk hole in advance before assembly.
