In the prior art, there is a wire clamp whose main body is in the shape of an "n", with left and right sides extending outward, and threaded holes provided on the extended parts. When fixing the wires, it is necessary to first place the cables on the electrical box, and then place the wire clamp so that the cables are located in the groove of the wire clamp main body. Finally, a torque tool is used to screw the screws through the threaded holes on the left and right sides to fix the wire clamp to the electrical box.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0025] The present invention provides a wire fixing clamp assembly and an electrical appliance box which can simplify wire fixing assembly steps, reduce workers' labor intensity, and improve production efficiency.

[0026] The following combination Figures 1 to 4 The technical solution provided by the present invention is described in more detail.

[0027] like Figures 1 to 4 As shown, the wire clamp assembly provided by the present invention includes a wire clamp body 1 and a fixing portion 2 provided on the wire clamp body 1. The fixing portion 2 can be engaged with the component to be connected and form an accommodating space between at least a portion of the wire clamp body 1 and the surface of the component to be connected.

[0028] The wire clamp assembly provided by the present invention comprises a wire clamp body 1 and a fixing portion 2 provided on the wire clamp body 1. The fixing portion 2 can be snap-fitted to a component to be connected (e.g., a box body 4 of an electrical box). During assembly, the wire clamp body 1 can be directly snap-fitted to the component to be connected by squeezing. Compared with the connection method of fastening with screws in the prior art, the snap-fit ​​method has higher installation efficiency during assembly, omits small components such as screws, makes operation simpler, and reduces manual labor intensity.

[0029] As a preferred or optional embodiment, the wire clamp body 1 includes a first clamp body 11 and a second clamp body 12, and the first clamp body 11 and the second clamp body 12 are both provided with a fixing portion 2, which can be snapped into the box body 4 of the electrical box and can be rotated or moved relative to the box body 4; the first clamp body 11 is provided with a first connecting portion 13, and the second clamp body 12 is provided with a second connecting portion 14, and the first connecting portion 13 and the second connecting portion 14 can be snapped into each other.

[0030] Specifically, during assembly, the first clamp body 11 and the second clamp body 12 are first fixed to the box body 4 respectively, and then the cables are arranged and placed between the first clamp body 11 and the second clamp body 12, and finally the first clamp body 11 and the second clamp body 12 are rotated or moved so that the first connecting part 13 and the second connecting part 14 thereon are engaged, thereby fixing the cables in the gap between the box body 4 and the wire fixing clamp assembly; the conventional wire fixing clamp is made into a split design of the first clamp body 11 and the second clamp body 12, which can play a certain limiting role on the cables during the sorting process, reduces the cable sorting time, and can effectively fix the cables.

[0031] As a preferred or optional embodiment, the fixing portion 2 includes a fastening head 21 and a connecting shaft 22 , and a radial outer contour dimension of the fastening head 21 is larger than an outer diameter of the connecting shaft 22 .

[0032] Specifically, if Figures 1 and 2 It can be seen that a cross-shaped groove is provided on the fastening head 21. During installation, it is only necessary to align the fastening head 21 with the connecting hole 41 on the box body 4 and press the side of the first clamp 11 or the second clamp 12 away from the fastening head 21. The cross-shaped groove provides an extrusion and deformation space for the fastening head 21. After the fastening head 21 is deformed and passes through the connecting hole 41, it returns to its natural state due to its own elastic force, thereby realizing a snap-on connection; after the snap-on connection is completed, the first clamp 11 and the second clamp 12 can respectively rotate around their respective connecting axes 22.

[0033] As a preferred or optional embodiment, the first connecting part 13 and the second connecting part 14 each include at least two clamping columns 131, and a column head 132 is provided at the end of each clamping column 131. The outer diameter of the column head 132 is larger than the outer diameter of the clamping column 131, and there are clamps and gaps 133 between adjacent clamping columns 131 that are adapted to the column heads 132.

[0034] Specifically, during installation, the column head 132 located on the first connecting part 13 and the column head 132 located on the second connecting part 14 squeeze each other to achieve fastening; this structure can withstand a tensile force of at least 200N, meeting the line fixing requirements, and when subjected to a tensile force of 100N, the relative displacement between the two is only 2mm; preferably, the column head 132 is set to be spherical.

[0035] As a preferred or optional embodiment, the gaps 133 between adjacent clamping posts 131 are smaller than the outer diameter of the post heads 132 .

[0036] As a preferred or optional embodiment, at least three rows of clamping posts 131 are provided along the extension direction of the first clamping body 11 ; and / or at least three rows of clamping posts 131 are provided along the extension direction of the second clamping body 12 .

[0037] Specifically, the extension direction of the first clamp body 11 and the second clamp body 12 refers to the direction extending from the fixing part 2 to the first connecting part 13 or the second connecting part 14; by providing multiple rows of clamping columns 131, the overlapping length between the first connecting part 13 and the second connecting part 14 can be selected according to the outer diameter of the cable, so that the application range of the wire clamp assembly is wider.

[0038] As a preferred or optional embodiment, the first connecting portion 13 includes a mounting hole, and the second connecting portion 14 includes a clamping column 131 , and the clamping column 131 is connected to the mounting hole by clamping or interference fit.

[0039] Specifically, when the first connecting part 13 and the second connecting part 14 are engaged, the clamping column 131 is inserted into the mounting hole. The structure of the clamping column 131 can be as described above, and its column head 132 can be fixedly connected by passing through the mounting hole through its own deformation or deformation of the mounting hole, or the clamping column 131 is fixedly connected with the mounting hole through interference fit.

[0040] As a preferred or optional embodiment, at least two mounting holes are provided along the extension direction of the first clamping body 11; and / or at least two clamping posts 131 are provided along the extension direction of the second clamping body 12. Providing multiple rows of mounting holes or clamping posts 131 allows the overlap length between the first connecting portion 13 and the second connecting portion 14 to be selected according to the outer diameter of the cable, thereby expanding the applicability of the cable clamp assembly.

[0041] As a preferred or optional embodiment, the first clamping body 11 and the second clamping body 12 are arc-shaped structures, and the cable clamp assembly forms an arch structure after the first connecting portion 13 and the second connecting portion 14 are engaged. Thus, the accommodating space 3 is formed between the arch structure and the surface of the box body 4 for accommodating the cable.

[0042] The electrical box provided by the present invention comprises a box body 4 and a wire clamp assembly provided by any technical solution of the present invention.
