[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference below Figure 1-Figure 5 The invention describes a plug-resistant and anti-interference power cord according to an embodiment of the utility model.

[0036] like Figure 1-Figure 5 As shown, the plug-resistant and anti-interference power cord includes a cable 310, a three-pin plug 100 and an electrical plug 320. One end of the cable 310 is connected to the three-pin plug 100, and the other end is connected to the electrical plug 320. Specifically, the length of the cable 310 and the structure of the electrical plug are selected according to the corresponding length and specified specifications according to actual production. The main invention of this embodiment lies in the three-pin plug 100.

[0037] The three-pin plug 100 includes a socket head 120 and a wire pull seat 200. A three-pin pole piece 110 is extended at one end of the socket head 120, and a bending portion 130 is provided at the connection between the socket head 120 and the cable 310. The bending portion 130 is usually used to improve the connection strength between the socket head 120 and the cable 310 in the prior art center. The wire pull seat 200 is sleeved at the bending portion 130 and is integrally formed with the bending portion 130. The diameter of the wire pull seat 200 is larger than the diameter of the end of the socket head 120, which is convenient for the user to hold the wire pull seat 200 to pull out the socket head 120. In actual production, the wire pull seat 200 is wrapped at the bending portion 130 through a post-processing process, and the user uses the wire pull seat 200 as a leverage point to pull out the socket head 120 in the socket.

[0038] The two side walls of the socket head 120 are formed with trimmed abutment surfaces 121, which are used to reduce the lateral width of the socket head 120. When the five-hole socket is in a structure where three holes and two holes are arranged side by side horizontally, the trimmed abutment surfaces 121 of the socket head 120 can reduce the lateral occupied area of ​​the three-pin plug 100, so that the two-pin plug can be inserted normally.

[0039] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the cross section of the socket head 120 is in the shape of a racetrack.

[0040] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5As shown, the ground wire electrode of the three-pin electrode 110 is 4mm to 6mm away from the edge of the socket head 120, and the positive and negative electrodes of the three-pin electrode 110 are 4.5mm to 6mm away from the trimmed abutment surface 121 of the socket head 120. Specifically, the distance between the top edge of the three-pin electrode 110 and the socket head 120 is 4.7mm, which can be applied to the socket structure with three holes and two holes arranged vertically, and prevent the top of the socket head 120 from interfering with the two-pin plug. The existing socket head 120 is set with a safety distance to prevent the user's fingers from accidentally touching the three-pin electrode 110 during the plug-in and unplug process. After the utility model is provided with the pull-out socket 200, the user does not need to pull out the three-pin electrode 110 through the socket head 120, which improves safety and can reduce the occupied area of ​​the socket head 120, thereby making it possible to insert the three-pin plug 100 and the two-pin plug into the five-hole socket at the same time.

[0041] In some embodiments of the present invention, Figure 2 , Figure 3 and Figure 5 As shown, a positioning portion 122 is arranged around the socket head 120 at one end of the socket head 120 near the wire puller 200, and the positioning portion 122 is used to assist the three-pin plug 100 to be plugged into the socket. Specifically, the positioning portion 122 is convenient for the user to hold, so that the user can insert the three-pin pole piece 110 into the corresponding socket hole through the positioning portion 122.

[0042] The positioning portion 122 includes two implementations according to the setting structure.

[0043] In the first embodiment, the positioning portion 122 is protruded from the side wall of the socket head 120. That is, the positioning portion 122 is a convex block, and the user holds the positioning portion 122 with two fingers to insert the triangular plug.

[0044] In Example 2, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the positioning portion 122 is recessed inwardly on the surface of the socket head 120. Specifically, the positioning portion 122 is recessed inwardly on the surface of the socket to form a groove, and the user's fingers can be inserted into the groove to hold the socket head 120.

[0045] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the diameter of the wire puller 200 is smaller than the maximum diameter of the socket head 120. Avoid the wire puller 200 being too large to affect the arrangement of the three-pin plug 100 and other plugs on the five-hole socket.

[0046] In some embodiments of the present invention, Figure 3 and Figure 5As shown, the edge of the wire puller 200 is arranged in an arc shape near the socket head 120. Specifically, when the user touches the wire puller 200 and pulls out, the arc transition can improve the grip of the wire puller 200 and prevent the edge of the wire puller 200 from cutting the hand.

[0047] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the end of the wire puller 200 away from the socket head 120 is provided with a protective ramp 210, which is integrally formed with the wire puller 200 and wraps the bent portion 130. Specifically, the protective ramp 210, as an extension of the wire puller 200, can play the role of transition connection, and its role on the bent portion 130 is the same.

[0048] In some embodiments of the present invention, the sidewall of the wire puller 200 is provided with an anti-skid texture (not shown in the drawings). Specifically, the anti-skid texture mainly plays an anti-skid role to prevent the user from slipping when holding the wire puller 200.

[0049] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
