DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0023] Reference example Figures 1 to 3 An electric energy meter box includes a box body 1, which is provided with a wire inlet hole 11 and a plurality of wire outlet holes 12. The wire inlet hole 11 and the wire outlet hole 12 are provided with a support column 2. A rubber wire column 3 is provided inside the support column 2. The rubber wire hole is evenly distributed with a plurality of wire holes 31 with a circle as the axis. The rubber wire column 3 is provided with a tapered through hole 32. A liftable wire fixing column 4 is provided inside the support column 2. The wire fixing column 4 is provided with a tapered abutment portion 41 and abuts the through hole 32.

[0024] It is worth mentioning that the support column 2 is provided with a fixing flange 21, which abuts against the end faces of the inlet hole 11 and the outlet hole 12. The fixing flange 21 connects and fixes the support column 2 with the inlet hole 11 and the outlet hole 12;

[0025] It is worth mentioning that the support column 2 is provided with a cavity 22 for accommodating the rubber wire rod 3. A threaded portion 23 is provided at one end of the cavity 22. The threaded portion 23 is evenly distributed with a number of equally spaced support frames 24 with a circular point as the axis. The threaded portion 23 is provided with a threaded hole 231. The threaded portion 23 provides support for the rubber wire hole and limits the sinking distance of the fixed wire column 4.

[0026] It is worth mentioning that the rubber wire column 3 is provided with a groove 33 corresponding to the support frame 24, and the threading hole 31 is set between the support frames 24. When the fixed wire column 4 is rotating, friction is generated, and the support frame 24 provides a support point for the groove 33 to prevent the rubber wire column 3 from rotating, ensuring that the threading hole 31 is always between the support frames 24.

[0027] It is worth mentioning that one end of the wire-fixing cylinder 4 is provided with a screw 44, which is threadedly connected to the threaded hole 231. The screw 44 is provided with a retaining ring 5. The other end of the wire-fixing cylinder 4 is provided with an operating portion 42 and a nut portion 43. The screw 44 is threadedly connected to the threaded hole 231 to make the wire-fixing cylinder 4 rise and fall in the through hole 32. The retaining ring 5 limits the rising distance of the wire-fixing cylinder 4. When the rotation resistance is large, a tool can be used to engage the nut portion 43 to rotate the wire-fixing cylinder 4.

[0028] It is worth mentioning that a spring 6 is provided inside the wire fixing column 4 and abuts against the threaded portion 23 . The elastic force released by the spring 6 increases the friction between the screw 44 and the threaded hole 231 , ensuring that the wire fixing column 4 is fixed in the rotated position.

[0029] The operating principle of the present invention is now described as follows:

[0030] Pass the wires through the threading holes 31 one by one, and rotate the wire fixing column 4 through the operating part 42. As the wire fixing column 4 gradually sinks, the diameter of the tapered contact portion 41 is larger at the top and smaller at the bottom. The contact portion 41 will gradually expand the through hole 32, and the threading hole 31 will be squeezed and deformed by the contact portion 41, so that the wire placed in the threading hole 31 fits tightly with it, which not only fixes the wire but also prevents external dust and moisture from entering the box body 1.

[0031] The above design solution can enable the product to achieve the advantages of good line fixing effect and ensure stable electrical connection.

[0032] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
