At present, the plug and socket standards implemented by many countries have clear requirements for the pull-out force of the plug, which not only considers the reliability of the electrical connection, but also satisfies the user experience of easy plugging and unplugging. However, this requirement also brings some inconvenience. When the power cord of the plug or socket is pulled by mistake, the tension on the power cord can easily cause the plug to loosen or fall off. For example, the user accidentally trips on the plug or socket while walking. Power cord, or accidentally pulled the power cord of the plug or socket when handling something, causing the plug to loosen or fall off. Hereinafter, the power cord of the plug is referred to as the plug power cord for short, and the power cord of the socket is referred to as the socket power cord for short.

Fig. 1 is a schematic diagram of a three-dimensional structure of a socket according to some embodiments of the present disclosure; Fig. 2A is a top view of a plug plugged into the socket shown in Fig. 1; Fig. 2B is another socket according to some embodiments of the present disclosure The top view with the plug inserted; Figure 3 is the left side view of Figure 1. Some embodiments of the present disclosure provide a socket 1. As shown in FIGS. 1 and 2A, the socket 1 includes a socket outer shell 11 and at least one wire clamp 12, for example, two wire clamps 12 are shown in FIGS. 1 and 2A. . The socket housing 11 includes at least one socket 111, and the socket 111 is configured to mate with the plug 2. The socket 111 is a two-hole socket, a three-hole socket or a five-hole socket. 6 sockets 111 are shown in FIGS. 1 and 2A, and the socket 111 shown is a five-hole socket. As shown in Figures 2A and 3, at least one clamping clip 12 is provided on the socket housing 11, and cooperates with the socket housing 11 to form a clamping hole 122. The clamping hole 122 is configured to allow the plug power cord 21 to pass through. The section of power cord 21 between the plug 2 and the clamping hole 122 is restricted from moving relative to the socket 1. At least one clamping clamp 12 can clamp the plug power cord 21. When the user accidentally trips or pulls on the plug power cord 21, the plug power cord 21 is restricted by at least one clamp 12, and the plug 2 reaches the clamping hole 122. The power cord 21 in between cannot move relative to the socket 1 so that the plug 2 will not loosen or fall off from the socket 111 of the socket 1.

Some embodiments of the present disclosure do not make too rigid restrictions on the number, extension direction, and position of at least one wire clip 12 on the socket 1. Those skilled in the art can implement the implementation provided in the present disclosure according to actual usage requirements. Make reasonable modifications based on the example. For example, the number of at least one clip 12 may not be limited to two, and may also be one, or three, or more than three. For example, the at least one clip 12 may extend along the width direction of the socket 1 as shown in FIG. 2A, or may extend along the length direction of the socket 1 as shown in FIG. 2B. For another example, as shown in FIG. 9, at least one wire clamp 12 may be provided on the same surface of the socket housing 11 as the socket 111; further, at least one wire clamp 12 may be located as shown in FIGS. 2A and 2B. The two top corners on the left side of the socket 1 can also be located at the two top corners on the lower side of the socket 1 as shown in Figure 7, or can also be located at the top left and right corners of the socket 1 as shown in Figure 8. At the bottom corner. As shown in FIG. 10, at least one wire clamp 12 and the socket 111 can also be arranged on different faces of the socket housing 11, and at least one wire clamp 12 and the socket 111 can be arranged on two opposite faces, or can be arranged On two adjacent faces.

In some embodiments of the present disclosure, the socket housing 11 may be a rectangular parallelepiped, a cylinder, or the like. As shown in Figure 1, when the socket housing 11 is a rectangular parallelepiped, the sockets 111 are arranged side by side on the surface of the socket housing 11; when the socket housing 11 is cylindrical, the sockets 111 are arranged on the circular surface of the socket housing 11. Distributed around its center.

As shown in Figures 2A and 2B, and Figures 3 to 6, the socket 1 is a rectangular parallelepiped. For ease of description, the thickness direction of the socket 1 is referred to as the P direction, the length direction of the socket 1 is referred to as the R direction, and the socket The width direction of 1 is called the Q direction. In some embodiments, the length of the socket 1 is greater than or equal to the width of the socket 1.

If the distance between the inner wall of the at least one clamp 12 and the surface of the socket housing 11 (the height of the clamp hole 122 in the P direction) is too large, the clamping force of the at least one clamp 12 on the plug power cord 21 It is small. When the plug power cord 21 is pulled by an external force, the plug power cord 21 may move relative to the socket 1, thereby causing the plug 2 to loosen or fall off. Therefore, in order to ensure the clamping force of the plug power cord 21 by the at least one wire clamping clip 12, the distance between the inner wall of the at least one wire clamping clip 12 and the surface of the socket housing 11 is smaller than the diameter of the plug power cord 21. However, if the distance is too small, the clamping force of at least one clamp 12 on the plug power cord 21 is too large, and the pulling force required to remove the plug power cord 21 from the at least one clamp 12 is large, which is not only laborious, but also During the removal process, at least one clip 12 is easily damaged. Therefore, considering the diameter of the existing plug power cord 21, the distance between the inner wall of the at least one clamp 12 and the surface of the socket outer shell 11 is 6.5 mm-7 mm. For example, the pitch is 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, or 7mm.

In some embodiments of the present disclosure, as shown in FIG. 2A, the extension direction (R direction) of the plug power cord 21 passing through the at least one clip 12 is the same as the plug power source connected to the plug 2 inserted in the at least one socket 111 The extension direction (Q direction) of the wire 21 has an included angle, for example, the included angle is 90 degrees; as shown in FIG. The extension direction (Q direction) of the plug power cord 21 to which the plug 2 inserted into one socket 111 is connected is parallel.

It should be noted that although FIG. 2A only shows the extension direction of the power cord 21 passing through the at least one clip 12 and the extension direction of the power cord 21 connected to the plug 2 inserted in the at least one socket 111 The included angle between is 90°, but the included angle can be any degree, for example, 30°, 60°, 120°, 150°, and so on.

In addition to Figure 3, Figures 4 to 6 also provide side views of other sockets. In some embodiments of the present disclosure, as shown in FIGS. 3 to 6, at least one clip 12 includes a first bending portion 123, a main body portion 124 and a second bending portion 125. The first end of the first bending portion 123 is connected to the first end of the main body portion 124, and the first end of the second bending portion 125 is connected to the second end of the main body portion 124. The main body portion 124 may be a flat surface or an arc surface, and the distance between the inner wall of the main body portion 124 and the socket housing 11 forms a wire clamping hole 122.

In order to allow the plug power cord 21 to pass through the wire clamping hole 122, the length of the main body 124, that is, the size of the main body 124 extending from the first bent part 123 to the second bent part 125 is greater than the diameter of the socket power cord 21. In FIGS. 3 to 6, the length of the main body 124 is a dimension extending in the Q direction.

And it can be understood that when a plurality of plugs 2 are inserted into the socket 1, so that there are a plurality of plug power cords 21 corresponding to the plurality of plugs 2, in order to make the clamping hole 122 for the plurality of plug power cords 21 to pass through. However, the length of the main body 124 is greater than the sum of the diameters of the multiple plug power cords 21. For example, when the wire clamping hole 122 is to allow three plug power cords 21 to pass through, the length of the main body 124 is greater than three plug power cords. The sum of the diameters of 21.

The second end of the first bending portion 123 away from the main body portion 124 is fixedly connected to the socket housing 11. As shown in FIG. 3, the second end of the first bending portion 123 may be integrally formed with the socket outer shell 11; as shown in FIG. 4, the second end of the first bending portion 123 may also be detachable from the socket outer shell 11. Ground connection, for example, the second end of the first bent portion 123 is connected to the socket housing 11 by a screw.

As shown in FIGS. 3 and 4, the second end of the second bending portion 125 away from the main body portion 124 may have a distance from the surface of the socket housing 11; as shown in FIGS. 5 and 6, the second bending portion The second end of 125 away from the main body portion 124 may also abut on the surface of the socket housing 11.

As shown in Figures 3 and 4, there is a gap between the second end of the second bent portion 125 and the surface of the socket housing 11, and the gap forms an inlet 121 through which the plug power cord 21 enters the clip.线孔122内。 Line hole 122. A squeezing force is applied to the second end of the second bending portion 125 through the plug power cord 21, so that after a certain deformation of the second end of the second bending portion 125 occurs, the plug power cord 21 can be squeezed into the wire inlet 121, In addition, a squeezing force is further applied, so that the plug power cord 21 can enter the clamping hole 122.

If the distance between the second end of the second bent portion 125 and the surface of the socket housing 11 (that is, the height of the wire inlet 121 along the P direction) is too large, the plug power cord 21 will easily slip out of the wire inlet 121 . In order to avoid the above situation, the distance is smaller than the distance between the inner wall of the main body portion 124 and the surface of the socket housing 11 (that is, the height of the wire clamping hole 122 in the P direction). When the user pulls the plug power cord 21 by mistake, the plug power cord 21 is subjected to the squeezing force of the inner wall of the main body portion 124 and the resistance of the inner wall of the second bending portion 125, and it is not easy to slip out of the wire clamping hole 122. If the height of the wire inlet 121 is too small, the squeezing force of the plug power cord 21 when it enters the wire inlet 121 is too large, which may easily cause damage to at least one wire clamp 12. Therefore, the height of the wire inlet 121 is in the range of 3 mm to 4 mm, for example, 3 mm, 3.25 mm, 3.5 mm, 3.75 mm, or 4 mm.

As shown in Figures 5 and 6, the second end of the second bending portion 125 away from the main body portion 124 abuts on the surface of the socket housing 11, when the plug power cord 21 is to enter the clamping hole 122, the user When an upward force is applied to the second bending portion 125, the second end of the second bending portion 125 is elastically deformed, and is separated from the surface of the socket housing 11 to form a certain distance, and the plug power cord 21 enters the clamping hole through this distance Within 122. At this time, the user removes the force applied to the second bending portion 125, and the second end of the second bending portion 125 returns to the state of abutting the socket housing 11, so that the plug power cord 21 is not easy to pass through the clamping hole 122 Prolapse.

In some embodiments of the present disclosure, as shown in FIG. 6, the second end of the first bending portion 123 and the second end of the second bending portion 125 respectively abut two opposite surfaces of the socket housing 11, and The opposite squeezing force is generated on the two opposite surfaces of the socket housing 11, so as to realize the relative fixation between the at least one wire clamp 12 and the socket housing 11, and between the plug power cord 21 and the socket 1.

In some embodiments of the present disclosure, the socket 1 further includes a socket power cord 13 and a socket switch 14. The socket power cord 13 passes through the socket housing 11, and at least one clip 12 is located on the socket housing 11 close to the socket power cord 13. Or at least one clip 12 is located on the side of the socket housing 11 away from the power cord 13 of the socket. The latter can prevent the plug power cord 21 and the socket power cord 13 from being entangled. The socket switch 14 is configured to control the socket 1 to be energized. For example, when the user presses the socket switch 14 to sink the socket switch 14 into the socket housing 11, the socket 1 is energized; when the user presses the socket switch 14 to make the socket switch 14 pop out of the socket housing 11, the socket 1 is powered off.

The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited to this. Any person skilled in the art who thinks of changes or substitutions within the technical scope disclosed in the present disclosure shall cover Within the protection scope of this disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
