[0004] In practical use, traditional single-wire hole sealing typically involves filling the gaps around the power interface with polyurethane potting compound, which cures to form a tough and well-sealing layer. Therefore, if a wire inside the single-wire hole malfunctions, the enclosure needs to be disassembled. However, the already sealed and cured single-wire hole can damage the enclosure or wiring during disassembly and repair, making the disassembly process cumbersome and increasing repair costs. Utility Model Content

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-4 An embodiment of this utility model provides a die-cast housing with a dual-hole power interface, including a housing 1. A wire hole 4 is provided on the inner wall of one side of the housing 1. A ring post 12 is fixedly connected to one side of the housing 1. The wire hole 4 passes through the housing 1 and the ring post 12. A fastening nut 13 is threadedly connected to the outer wall of the ring post 12. A guide cone 8 is fixedly connected to the side of the fastening nut 13 away from the housing 1. A sealing ring 9 is provided on the side of the guide cone 8 away from the fastening nut 13.

[0025] In this embodiment, Figure 1 The orientation is indicated by the front, back, left, and right sides. Specifically, there are two wire holes 4 and two ring posts 12. The two wire holes 4 can be used to install two lines or lines with different voltages. The wire passes through the housing 1 and the ring post 12 through the wire hole 4, and then through the guide cone 8, the ring post 12, and the housing 1, and fits against the sealing ring 9. The connection between the ring post 12 and the housing 1 provides support for the ring post 12. The threaded connection between the ring post 12 and the fastening nut 13 allows the fastening nut 13 to be installed on the ring post 12, thus completing the installation of the guide cone 8. When it is necessary to disassemble the interface, the fastening nut 13 and the ring post 12 are separated to disassemble the power interface. This solves the problem that the traditional single wire hole can damage the housing 1 or the lines during disassembly and maintenance, making the disassembly process cumbersome and increasing the maintenance cost.

[0026] Reference Figures 2-4 There are two wire holes 4 and two ring posts 12. An external connection hole 11 is opened on one side of the housing 1. The ring post 12 is located inside the external connection hole 11. A sealing gasket 7 is provided on the outer wall of the ring post 12. One side of the sealing gasket 7 is attached to the fastening nut 13, and the other side of the sealing gasket 7 is attached to the inner wall of the external connection hole 11.

[0027] Specifically, through the design of the external connection hole 11, after the fastening nut 13 and the ring post 12 are connected and tightened, one side of the fastening nut 13 is attached to the sealing gasket 7, and at the same time, it compresses the sealing gasket 7, so that the left side of the sealing gasket 7 is attached to the inner wall of the external connection hole 11, thereby improving the dustproof and waterproof capability of the power interface.

[0028] Reference Figures 3-4 The outer wall of the ring post 12 is provided with an external thread 6, which is connected to the inner wall thread of the fastening nut 13.

[0029] Specifically, when installing or removing the power interface, the fastening nut 13 and the ring post 12 are separated by the threaded connection of the external thread 6 and the fastening nut 13, thereby achieving the convenience of removing and installing the power interface.

[0030] Reference Figures 3-4 A conical clamp 10 is fixedly connected to the side of the ring column 12 away from the box body 1, and the outer wall of the conical clamp 10 and the inner wall of the sealing ring 9 are in contact.

[0031] Specifically, the conical clip 10 is made of rubber. When the fastening nut 13 is installed on the ring post 12, the conical clip 10 slides into the inside of the guide cone 8, and through the guide cone 8, the right outer wall of the conical clip 10 and the right inner wall of the guide cone 8 fit together. When the fastening nut 13 is installed, the right side of the conical clip 10 forms a circle and fits with the left side of the sealing ring 9, thereby achieving the sealing of the power interface.

[0032] Reference Figures 1-2 The wire 2 is installed inside the wire hole 4.

[0033] Specifically, the redundancy of the enclosure 1 is improved by using two wires 2. When one of the wires 2 is damaged, the other wire 2 can be used, or different voltage outputs can be achieved by using two wires 2, thereby improving the applicability of the enclosure 1.

[0034] Reference Figures 2-4 The outer wall of the wire 2 is attached to the inner wall of the guide cone 8, the outer wall of the wire 2 is attached to the inner wall of the cone clamp 10 on the side away from the box 1, and the outer wall of the wire 2 is attached to the inner wall of the sealing ring 9.

[0035] Specifically, the sealing performance of the power interface is improved by the fit between the wire 2 and the inner wall of the sealing ring 9, and the stability of the wire 2 is improved by the fit between the wire 2 and the tapered clamp 10.

[0036] Reference Figures 1-2 A wire clamp 3 is provided on the upper side of the wire 2, and the bottom of the wire clamp 3 is provided on the inner bottom wall of the box 1.

[0037] Specifically, the connection between the single wire 2 and the housing 1 is improved by using the wire clamp 3, thereby improving the stability of the power interface.

[0038] Reference Figure 2 A wire clamp 2 5 is provided on the inner bottom wall of the box 1, and the ends of the two wires 2 away from the ring post 12 are located between the wire clamp 2 5 and the box 1.

[0039] Specifically, the two wires 2 are fixed together by the wire clamp 2 5. The friction between the two wires 2, as well as the friction between the wires 2 and the housing 1 and the wire clamp 2 5, further increases the stability of the power interface.

[0040] Working principle: Pass the wire 2 through the sealing ring 9 and the wire hole 4, leaving an appropriate length for the wire 2 located inside the housing 1. Connect the wire 2 to the external thread 6 and the fastening nut 13, and install the fastening nut 13 onto the ring post 12, so that the side of the fastening nut 13 near the ring post 12 abuts against the sealing gasket 7. At the same time, the side of the sealing gasket 7 away from the fastening nut 13 is close to the inner wall of the external connection hole 11. At this time, the outer wall of the tapered clamp 10 and the inner wall of the guide cone 8 are in contact, and the side of the tapered clamp 10 away from the ring post 12 forms a circle and is in contact with one side of the sealing ring 9. Then, fix a single wire 2 to the inner bottom wall of the housing 1 with the wire clamp 3, and fix two wires 2 together with the wire clamp 5 and clamp them to the inner bottom wall of the housing 1. Thus, the installation and sealing of the power interface are completed.

[0041] When it is necessary to disassemble the interface, release the clamps 1 and 2 from the wire 2, and remove the fastening nut 13 from the ring post 12 by rotating the fastening nut 13 and pull it out; thus completing the disassembly of the power interface. This solves the problem that traditional single-wire holes can damage the enclosure 1 or the wiring during disassembly and maintenance, making the disassembly process cumbersome and increasing maintenance costs.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
