Abstract

The invention discloses a safety socket. The safety socket comprises a shell, at least three guide pipes installed in the shell as well as a ground wire contact rod, a live wire contact rod and a null wire contact rod which respectively sleeve the guide pipes and can move along the guide pipes; the safety socket further comprises a first connecting rod of which one end is connected with the ground wire contact rod, a second connecting rod which is connected with the other end of the first connecting rod and a supporting rod which is used for supporting the first connecting rod; an open groove is formed at one end of the first connecting rod which is connected with the ground wire contact rod and is used for preventing mechanical clamping of relative movement of the first connecting rod and the ground wire contact rod; one end of the second connecting rod is connected with the live wire contact rod; the other end of the second connecting rod is connected with the null wire contact rod; and a distance from the ground wire contact rod to a ground wire jack in the shell is smaller than a distance from the null wire contact rod to a null wire jack in the shell and a distance from the live wire contact rod to a live wire jack in the shell. With the safety socket of the invention adopted, a plug can be constantly connected with a ground wire assuredly in plugging and pulling-out processes, and therefore, use safety can be greatly improved.

Example Embodiment

[0014] The implementation of this application will be described in detail below with the accompanying drawings and embodiments, so as to fully understand and implement the implementation process of how this application uses technical means to solve technical problems and achieve technical effects.

[0015] This embodiment provides a safe socket, such as figure 1 with 2 As shown, it includes a housing 1, three guide rods 6, 8 installed in the housing 1, and a ground contact rod 4 and a live contact rod respectively sleeved on the guide pipes 6, 8 and movable along the guide pipes 6, 8 And the neutral line contact rod 5, wherein the ground line contact rod 4 is sleeved on the guide tube 6, the live line contact rod and the neutral line contact rod 5 are sleeved on the two guide tubes 8 respectively; it also includes a first end connected to the ground contact rod 4 A connecting rod 10, a second connection connecting the other end of the first connecting rod 10, and a support rod 7 for supporting the first connecting rod 10; one end of the first connecting rod 10 connected to the ground contact rod 4 is provided with a slot, In order to prevent the first connecting rod 10 and the ground contact rod 4 from being mechanically stuck when they move with each other, one end of the second connecting rod 12 is connected to the live contact rod, and the other end is connected to the neutral contact rod 5;

[0016] In this embodiment, the distance from the ground wire contact rod 4 to the ground wire socket 3 on the housing 1 is smaller than the distance from the neutral wire contact rod 5 to the neutral wire socket 14 on the housing 1 and the distance from the live wire contact rod to the live wire on the housing 1 In order to achieve the minimum distance between the ground wire contact rod 4 and the ground wire jack 3 on the housing 1, two solutions can be used, as follows:

[0017] In the first type, one end of the ground contact rod 4 is connected with a spring 9 and the other end of the spring 9 is connected to the housing 1, and the spring 9 and the ground contact rod 4 are sleeved on the same guide tube 6 ;

[0018] In the second type, the length of the guide tube 6 is greater than that of the guide tube 8, and the bottom diameter of the guide tube 6 is larger than the diameter of the inner cavity of the ground contact rod 4, which can keep the ground contact rod 4

[0019] The first type is adopted in this embodiment.

[0020] In this embodiment, the guide rod is a hollow structure with a built-in wire, and the wire is connected to the ground contact rod 4 or the live contact rod or the neutral contact rod 5 sheathed on the guide rod.

[0021] In this embodiment, the support rod 7 is a telescopic rod, on which a spring (not shown in the figure) is sleeved. One end of the spring is connected to the first connecting rod 10 and the other end is connected to the housing 1.

[0022] In this embodiment, the ground wire socket 3, the live wire socket 13 and the neutral wire socket 14 of the housing 1 are provided with a pressing piece 2 for pressing the plug.

[0023] The working principle of this embodiment is as follows:

[0024] When the plug is inserted, the ground wire contact rod 4 is closer to the socket of the socket than the live wire and the neutral wire contact rod 5, so the ground wire is first connected to ensure safety;

[0025] When the plug is pulled out, first the live wire and the neutral wire contact rod 5 are separated from the copper sheet of the plug, and the ground wire is still conducting at this time, which ensures the safety of use.

[0026] The ground contact rod 4 of the present invention first contacts the plug when the plug is inserted, and finally separates from the plug when the plug is pulled out, ensuring that the plug is always connected to the ground wire during plugging and unplugging, which greatly improves the safety of use. Effectively avoid the danger when plugging and unplugging.

[0027] It should also be noted that the term "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed. Or it also includes elements inherent to this commodity or system. If there are no more restrictions, the element defined by the sentence "including a..." does not exclude the existence of other identical elements in the commodity or system that includes the element.

[0028] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as the exclusion of other embodiments, but can be applied to various embodiments. Such other combinations, modifications, and environments can be modified through the above teachings or technology or knowledge in related fields within the scope of the inventive concept described herein. However, modifications and changes made by those skilled in the art do not depart from the spirit and scope of the present invention, and should fall within the protection scope of the appended claims of the present invention.
