Referring to fig. 1 and 2, a socket 1 according to an embodiment of the present invention includes a socket outer shell 11 and a wire clamping structure 12, wherein the socket outer shell 11 is provided with one or more sockets 111, and the socket 111 is a five-hole socket, a two-hole socket or a three-hole socket; the wire clamping structure 12 is arranged on the socket outer shell 11, and a wire clamping direction R of the wire clamping structure 12 forms an included angle with a central line (a dotted line shown in fig. 2) of the jack 111; when the plug 2 is inserted into the jack 111, the wire clamping structure 12 can be used for the plug power wire 21 to pass through so as to limit the plug 2 from being pulled out of the jack 111.

The embodiment of the utility model provides a socket 1 includes socket shell body 11, has seted up one or more sockets 111 on the socket shell body 11, and this socket 111 is five hole sockets, two hole sockets or three hole sockets, and is used for cooperating with plug 2; compared with the prior art, the socket 1 of the embodiment of the present invention further includes a wire clamping structure 12, the wire clamping structure 12 is disposed on the socket outer shell 11, when the plug 2 is inserted into the socket 111, the wire clamping structure 12 can allow the plug power line 21 to penetrate therethrough, so as to limit the plug 2 from being pulled out of the socket 111; and because the card line direction R of the card line structure 12 has an included angle with the central line of the socket 111, the card line structure 12 changes the natural falling direction of the power line of the plug 2 under the action of gravity only, when the plug power line 21 is pulled directly by external force, the power line is limited by the card line structure 12, the pulling force F acting on the plug 2 is converted into a torsion M, and the torsion M cannot pull out the plug 2 from the socket 111 of the socket 1, as shown in fig. 2, thereby realizing the pull-off between the power line and the socket 1.

Alternatively, the wire clamping structure 12 may be a wire clamping groove directly formed on the outer socket housing 11, and the wire clamping groove is directly formed on the outer socket housing 11, and the structure and the assembly operation are simple. Optionally, the wire clamping structure 12 may also be a wire clamping clip, the wire clamping clip is fixedly connected to the socket outer housing 11, the mold of the existing socket outer housing 11 is changed slightly, and the wire clamping structure is simpler.

Based on the above embodiments, the structure of the clip has various structures, such as U-shaped, circular arc, polygonal, etc. In some possible embodiments, the wire clamping clip is a U-shaped elastic clip, one end of the U-shaped elastic clip is fixedly connected with the outer socket shell 11, the other end of the U-shaped elastic clip has a distance from the surface of the outer socket shell 11, the inner wall of the wire clamping clip and the surface of the outer socket shell 11 enclose a wire clamping opening 122, the distance is an inlet 121 of the wire clamping opening 122, as shown in fig. 3 and 4, the plug power wire 21 can enter the wire clamping opening 122 in the wire clamping clip through the inlet 121, and the wire clamping clip has a simpler shape and structure and is more convenient to manufacture.

Further, in order to guarantee the clamping force of the wire clamp on the plug power line 21, the embodiment of the present invention provides a distance between the inner wall of the wire clamp and the surface of the socket outer shell 11 is smaller than the diameter of the plug power line 21, after the plug power line 21 enters the wire clamping opening 122, the wire clamp can clamp the plug power line 21.

It should be noted that the distance between the inner wall of the wire clamping clip and the surface of the outer socket shell 11 should not be too small, otherwise the clamping force of the wire clamping clip on the plug power cord 21 is too large, the pulling force required for taking out the power cord from the wire clamping opening 122 is large, which not only takes a lot of labor, but also causes the wire clamping clip to be easily damaged during the taking-out process. Therefore, consider the diameter of current plug power cord, the embodiment of the utility model provides an interval between the inner wall of card line clamp and the surface of socket shell body 11 is 6.5 ~ 7 mm.

In order to prevent the plug power cord 21 from slipping out of the inlet 121, in some possible embodiments, the distance between the inner wall of the clip and the surface of the socket outer housing 11 is smaller than the distance between the end of the clip and the socket outer housing 11 (i.e., the length of the inlet 121 in the direction P in fig. 3), and the plug power cord 21 applies a pressing force to the inlet 121 so that the plug power cord 21 can be squeezed into the inlet 121 after the inlet 121 is deformed to some extent, and further applies a pressing force so that the plug power cord 21 can enter the cord clamping opening 122; for the mistaken collision of the plug power cord 21, the plug power cord 21 is not easy to slide out of the cord clamping opening 122 because of the extrusion force of the cord clamping clip and the resistance of the wall surface of the cord clamping clip near the inlet 121.

Similarly, in order to prevent the plug power cord 21 from entering the inlet 121 with too large extrusion force, the height of the inlet 121 cannot be too small, otherwise the wire clip is easily damaged, and therefore, the embodiment of the present invention provides that the height of the inlet 121 is 3.25 mm.

There are many sizes and types of existing sockets, and the number of sockets on the socket is different for different sizes or different types of sockets. In order to meet the anti-loose requirement of the socket with a plurality of jacks, the width of the wire clamping opening 122 (the width direction of the wire clamping opening 122 is the direction Q in fig. 3) is larger than the diameter of the plug power wire 21, for example, the width of the wire clamping opening 122 is the diameter of 3 plug power wires 21, or the width of the wire clamping opening 122 is the same as the width of the surface of the socket outer shell 11 opposite to the wire clamping clamp.

In order to avoid the excessive width of the wire clamping clip, the extrusion force that the wire clamping clip can bear is too small, so for a socket with more than two rows of sockets, the width of the socket 1 needs to be larger, in some possible embodiments, the wire clamping clip is multiple, multiple wire clamping clips are arranged at intervals, and multiple wire clamping clips can be respectively used for fixing the plug power wires 21 on the corresponding rows of sockets 111 on the socket outer shell 11.

For a socket with two rows of sockets, the number of the wire clamping clips on the outer socket shell 11 is two, the two wire clamping clips can be arranged oppositely (as shown in fig. 3 and fig. 4) or alternatively arranged, and the width of the wire clamping opening 122 in the two wire clamping clips is smaller than half of the width of the outer socket shell 111. Of course, in the case that the socket outer housing 11 is cylindrical and the insertion holes 111 are distributed around the center of the top surface of the socket outer housing 11, if the number of the insertion holes 111 is small, the number of the clip can be two; if the number of the insertion holes 111 is large, the number of the clip clamps can be plural, and a plurality of clip clamps are arranged along the top surface edge of the socket outer shell 11 at intervals.

Alternatively, the clip may be fixed to the receptacle housing 11 in various ways. If the clip is fixedly connected to the receptacle housing 11 by a fastener, or if the clip is integrally formed with the receptacle housing 11, the latter can reduce the assembly operation. Specifically, the fastener may be a screw.

Further, the embodiment of the present invention provides a socket 1 further including a socket power line 13, the socket power line 13 is disposed on the socket housing 11, the wire clip is located on one side of the socket housing 11 close to the socket power line 13, or the wire clip is located on one side of the socket housing 11 away from the socket power line 13. The latter can prevent the plug power cord 21 from being entangled with the receptacle power cord 13.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
