Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to an integrated C-shaped socket grounding clamp structure with high safety. Background Art

[0002] In daily life, power sockets, as the terminal interface devices for power transmission, are frequently used. Currently, the grounding components of European-style power sockets on the market are made of a separate grounding clip and a separate connecting strip riveted together, with only one riveted point.

[0003] However, the riveting process has limited and inconsistent connection strength. Insufficient riveting strength can cause relative movement between the grounding clamp and the connecting strip during production, transportation, and use. This movement further reduces the connection strength, creating a vicious cycle. Insufficient connection strength increases resistance at the joint, leading to heating when current flows through it, increasing safety risks and causing failures in certain standard tests (e.g., temperature rise). In extreme cases, the grounding clamp and connecting strip can separate, blocking the grounding circuit and posing a risk of electric shock to devices connected to the outlet.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an integrated C-type socket grounding clamp structure with high safety. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated C-type socket grounding clamp structure with high safety, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A technical solution for a highly secure integrated C-shaped socket grounding clamp structure comprises several grounding clamps, wherein an S-shaped connecting structure is provided between adjacent grounding clamps, and one of the outermost grounding clamps is provided with a protruding extension strip. The grounding clamp comprises a copper base strip, wherein vertical strips are provided at both ends of the copper base strip, and a C-shaped area is provided at the tail end of the vertical strip. The grounding clamp, S-shaped connecting structure, and protruding extension strip are an integral part obtained by stamping on a copper plate.

[0008] As a preferred technical solution, the connection between the S-shaped connection structure and the copper base bar is close to the vertical bar, which is conducive to increasing material utilization.

[0009] As a preferred technical solution, the second connection point between the protruding extension strip and the copper base strip is close to the vertical strip, which is conducive to saving materials.

[0010] As a preferred technical solution, the length of the protruding extension strip is adjustable, which helps to shorten the external power cord and save costs.

[0011] As a preferred technical solution, the tail of the protruding extension strip is provided with a large flat surface for connecting the copper wire of the power line.

[0012] As a preferred technical solution, a second through hole is provided in the middle of the large plane. When the copper wire is connected using the soldering process, the copper wire can pass through the second through hole to comply with relevant standard requirements; when a product without an external power cord is used, it is used to install the terminal; when the copper wire is connected using the spot welding process, the second through hole is cancelled, and the complete large plane facilitates the spot welding process.

[0013] As a preferred technical solution, the copper base strips, vertical strips and transition curved surfaces of the C-shaped area are provided with a whole-through reinforcing rib to increase the overall strength, clamping force, pressure resistance and torsional resistance of the grounding clamp.

[0014] As a preferred technical solution, the cross-section of the C-shaped area is designed to be U-shaped, which can withstand greater pressure and torsion and meet the requirements.

[0015] As a preferred technical solution, a through hole 1 is provided in the middle of the copper base strip for assembling and positioning the entire socket.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This utility model features a highly secure, integrated C-shaped socket grounding clamp structure. Its integrated design eliminates the strength risks associated with riveting in traditional structures. The S-shaped connection structure improves material utilization. The C-shaped area has a U-shaped cross-section, which is designed to withstand both pressure and torsion. The copper base bar, vertical bars, and continuous reinforcing ribs on the transitional surface increase the overall strength, clamping force, and resistance to pressure and torsion.

For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the present invention provides a technical solution for a highly secure integrated C-shaped socket grounding clamp structure: the structure includes a plurality of grounding clamps 1, with S-shaped connecting structures 2 provided between adjacent grounding clamps 1, and a protruding extension strip 3 provided on one of the outermost grounding clamps; the grounding clamp 1 includes a copper base strip 101, with vertical strips 102 provided at both ends of the copper base strip 101, and a C-shaped region 103 provided at the tail end of the vertical strip 102, and the cross-section of the C-shaped region 103 is U-shaped 106; the grounding clamp 1, the S-shaped connecting structure 2, and the protruding extension strip 3 are an integral part obtained by stamping on a copper plate.

[0027] Among them, the entire grounding clamp structure is an integrated part, eliminating the traditional riveting process, greatly improving the reliability of the connection and electrical safety performance; at the same time, it simplifies the three traditional processes of independent grounding clamp production, independent connecting strip production, and riveting the grounding clamp and connecting strip into one integrated grounding clamp production process, greatly improving production convenience and timeliness.

[0028] The S-shaped connection structure 2 is designed to allow for the use of free space when the multiple integral grounding clips are unfolded into a flat surface during stamping and forming, thereby improving material utilization. Depending on the design, the material utilization rate can be as high as 44% to 51%, varying with the number of grounding clips 1. The connection point 201 between the S-shaped connection structure 2 and the copper base strip 101 is designed to be as close as possible to the vertical strip 102, thereby increasing material utilization.

[0029] Among them, the protruding extension strip 3 is designed to minimize the distance from the entire grounding clamp structure to the power inlet of the whole machine socket, reduce the length of the external power cord extending into the socket, and make the L / N / E pole lengths of the external power cord consistent, which greatly facilitates production and saves costs.

[0030] Among them, the large flat surface 302 at the tail of the protruding extension strip 3 is used to facilitate the connection of the power cord to the grounding clamp structure by spot welding; if the power cord is connected by soldering, a second through hole 303 needs to be provided in the middle of the large flat surface 302, and then the copper wire is passed through the second through hole 303 and then high-temperature soldered to meet the requirements of relevant standards; if screw compression connection is used, the second through hole 303 can be used to pass screws or fix the terminal.

[0031] The reinforcing ribs 104 are used to increase structural strength, resistance to pressure, torsion and clamping force on the plug; and can return to their original position after the plug is removed.

[0032] The cross-section of the C-shaped region 103 is a U-shaped cross-section 106 , which is used to increase the strength of the grounding clamp end. Together with the reinforcing ribs 104 , it can meet the requirements of relevant standards for pressure, torque, and plug holding force.

[0033] The through hole 105 in the middle of the copper base strip 101 is used for assembly and positioning of the entire socket.
