Description

Technical Field

[0001] The utility model belongs to the technical field of sockets, and more specifically relates to a jack protection piece structure. Background Art

[0002] As Figure 4 shown, most of the current Australian-style socket triangular jacks are not required to be equipped with protection pieces by force. Because when connecting electrical appliances with triangular plugs, the grounding plug will be connected first to achieve the safety during electrical appliance connection. However, protection pieces are required for the double-hole jacks on the sockets. Therefore, the triangular jacks without protection pieces are likely to cause dust or other foreign objects to directly enter the L and N poles inside the socket, affecting the contact effect. At the same time, they can also be inserted by children with slender metals, resulting in electric shock accidents and poor safety. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a jack protection piece structure, which is provided with two protection pieces to reduce the entry of dust and improve safety.

[0004] To achieve the above object, the utility model provides the following technical solution: a jack protection piece structure, including a housing and an upper cover. A conductive copper sheet is arranged inside the housing. A support base is arranged between the housing and the upper cover. A protection cavity is arranged on the support base. A plurality of through holes corresponding to the conductive copper sheets are arranged on the protection cavity. A first protection piece and a second protection piece are slidably connected inside the protection cavity. A spring is arranged between the first protection piece and the second protection piece.

[0005] Further, a V-shaped notch is arranged on one side of the first protection piece away from the second protection piece. A fixing block corresponding to the V-shaped notch is arranged inside the protection cavity, and the fixing block is located on the side of the through hole.

[0006] Further, a guide rail groove is arranged on the support base. Guide blocks corresponding to the guide rail groove are arranged on both the first protection piece and the second protection piece.

[0007] Further, a groove corresponding to the grounding hole on the support base is arranged on the second protection piece.

[0008] Further, a spring hole is arranged on the first protection piece. A convex block corresponding to the spring hole is arranged on the second protection piece. One end of the spring extends into the spring hole, and the other end is sleeved on the convex block.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the first protection piece is pushed open, the second protection piece is pressed tightly by the compressed spring; when the second protection piece is pushed open, the first protection piece is pressed tightly. When the plug is pulled out, the protection piece will reset under the elastic force of the spring and block the through hole on the support base again. The first protection piece and the second protection piece that move towards each other protect all the jacks on the socket, reducing the entry of dust and improving safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In the description of the present utility model, it should be noted that for orientation terms, such as the terms "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and position relationships indicated are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present utility model.

[0016] In addition, for the terms "first" and "second", they are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meanings of "several" and "a number of" are two or more, unless otherwise specifically defined.

[0017] Refer toFigures 1 to 4 Further description of the present utility model.

[0018] A jack protection piece structure includes a housing 1 and an upper cover 2. A conductive copper sheet is arranged inside the housing 1. A support base 3 is arranged between the housing 1 and the upper cover 2. A protection cavity 16 is arranged on the support base 3. A plurality of through holes corresponding to the conductive copper sheets are arranged on the protection cavity 16. A first protection piece 4 and a second protection piece 5 are slidably connected inside the protection cavity 16. A spring 6 is arranged between the first protection piece 4 and the second protection piece 5.

[0019] As Figure 1 shown, preferably in this embodiment, inclined surfaces 7 are arranged on both the first protection piece 4 and the second protection piece 5. When a plug is inserted, the first protection piece 4 or the second protection piece 5 is pushed open by the wedging action of the inclined surface 7, and the inclined surfaces 7 between the first protection piece 4 and the second protection piece 5 face in opposite directions.

[0020] As Figure 1 shown, preferably in this embodiment, two springs 6 are arranged between the first protection piece 4 and the second protection piece 5.

[0021] As Figures 1 to 3 shown, all jacks on the socket are protected by the first protection piece 4 and the second protection piece 5 moving towards each other, reducing the entry of dust and improving safety.

[0022] Since only the triangular jack or the double-hole jack can be used when a socket is in use, when the first protection piece 4 is pushed open, the second protection piece 5 is pressed tightly by the compressed spring 6. When the second protection piece 5 is pushed open, the first protection piece 4 is pressed tightly. When the plug is pulled out, the protection piece will reset under the elastic force of the spring 6 and block the through holes on the support base 3 again.

[0023] As Figure 1 shown, preferably in this embodiment, a plurality of pressure rods 8 are arranged on the support base 3. The pressure rods 8 press the conductive copper sheets inside the housing 1. The upper cover 2 presses on the upper side of the support base 3, and the upper cover 2 is fixedly connected to the housing 1 with screws.

[0024] As Figure 1 and Figure 2 [[ID=3-4]]shown, preferably in this embodiment, a V-shaped notch 9 is arranged on the side of the first protection piece 4 away from the second protection piece 5. A fixing block 10 corresponding to the V-shaped notch 9 is arranged inside the protection cavity 16. The fixing block 10 is located on the side of the through hole.

[0025] As Figures 1 to 3 shown, preferably in this embodiment, a guide rail groove 11 is arranged on the support base 3. Guide blocks 12 corresponding to the guide rail groove 11 are arranged on both the first protection piece 4 and the second protection piece 5.

[0026] As Figure 3 shown, preferably in this embodiment, a groove 13 corresponding to the grounding hole on the support base 3 is provided on the second protective sheet 5.

[0027] As Figures 1 to 3 shown, preferably in this embodiment, a spring hole 14 is provided on the first protective sheet 4, a convex block 15 corresponding to the spring hole 14 is provided on the second protective sheet 5, one end of the spring 6 extends into the spring hole 14, and the other end is sleeved on the convex block 15.

[0028] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
