Description

Technical Field

[0001] The utility model relates to the technical field of power connectors, in particular to a switching plug with an elastic anti-dropping piece. Background Art

[0002] Plugs are connectors that connect electrical devices to sockets. Depending on the types of electrical devices, plugs can be roughly divided into two-pin plugs and three-pin plugs. In addition, plug standards vary between countries and regions, making it impossible for electrical devices in different countries and regions to be directly adapted and used. Therefore, adapter plugs are required. By connecting the adapter of the corresponding standard to the plug body of the electrical device, the electrical device can be adapted to sockets of different standards.

[0003] However, the connection stability of the existing adapter plug to the original plug of the electrical equipment is poor. The adapter plug is easily detached from the plug body due to uncontrollable external force factors (such as vibration, pulling, etc.), affecting the use of the electrical equipment, especially the electrical equipment that needs to operate 24 hours a day. If the user fails to discover and re-tighten it in time, this will affect the service life of the electrical equipment and bring certain safety hazards. Utility Model Content

[0004] The utility model aims to solve the above-mentioned deficiencies in the prior art and to provide a conversion plug with an elastic anti-dropping member, which can firmly connect the conversion plug to the original plug of the electrical equipment.

[0005] The purpose of the utility model is achieved in this way:

[0006] A conversion plug with an elastic anti-dropout part comprises a shell and an upper cover, wherein an installation cavity is provided in the shell, and the upper cover covers the opening of the installation cavity, a plurality of pins are arranged on the shell, and a plurality of conductive terminals are arranged in the installation cavity, and one end of the conductive terminal is connected with the pins. The invention is characterized in that an elastic anti-dropout part is also fixed in the installation cavity, an elastic anti-dropout hole is provided on the elastic anti-dropout part corresponding to the other end of the conductive terminal, and a plug-in through hole is provided on the upper cover corresponding to the elastic anti-dropout hole. This conversion plug with an elastic anti-dropout part has an elastic anti-dropout part provided on the installation cavity. When the conversion plug is connected with the original plug, the pin on the original plug passes through the plug-in through hole and the elastic anti-dropout hole and is connected with the other end of the conductive terminal, and the pin on the original plug is clamped by the elastic anti-dropout part, thereby ensuring that the connection between the pin on the original plug and the conductive terminal is firm, so that the conversion plug is not easily loosened due to external force factors, thereby improving the use safety and equipment life of the electrical equipment.

[0007] The purpose of the utility model can also be solved by the following technical measures:

[0008] Specifically, the elastic anti-dropping component is provided with a plurality of elastic clamping parts, and the plurality of elastic clamping parts are evenly distributed along the outer circumference of the elastic anti-dropping hole, and the inner diameter of the elastic anti-dropping hole is smaller than the inner diameter of the plug-in through hole; so that when the pin of the original plug is inserted into the elastic anti-dropping hole, the elastic clamping part will be pushed to undergo elastic deformation, thereby making the pin of the original plug elastically offset against the plurality of elastic clamping parts, thereby improving the connection firmness.

[0009] Specifically, a hollow portion is provided between two adjacent elastic clamping portions on the elastic anti-slip component; the hollow portion can make the elastic clamping portion more elastic and is more conducive to the stable operation of the elastic clamping portion.

[0010] Specifically, the elastic clamping portion is gradually bent downward in an arc shape from the outside of the elastic anti-dropping piece toward the elastic anti-dropping hole; this not only facilitates the insertion of the pin of the original plug into the elastic anti-dropping hole, but also makes it difficult for the pin of the original plug to fall out after being inserted into the elastic anti-dropping hole.

[0011] Specifically, it also includes a seating seat, which is placed on the installation cavity and is located above the other end of the conductive terminal. A through hole is opened on the seating seat corresponding to the other end of the conductive terminal. The seating seat also has a first limit block and a second limit block extending upward, and the first limit block and the second limit block are respectively located on the outer periphery of the through hole. A limiting space is enclosed between the seating seat, the first limit block and the second limit block, and the elastic anti-slip component is placed on the limiting space; the limiting space of the seating seat provides a stable installation space for the elastic anti-slip component, which is conducive to the stable operation of the elastic anti-slip component.

[0012] Specifically, a plurality of supporting blocks are further provided on the limiting space, and the elastic anti-slip component is placed on the plurality of supporting blocks; the plurality of supporting blocks play a better role in supporting the elastic anti-slip component, and also create a gap between the elastic anti-slip component and the surface of the mounting seat, and the gap provides a movable space for the deformation of the elastic clamping part on the elastic anti-slip component.

[0013] Specifically, a boss is fixed on the installation cavity, and one end of the boss passes through the installation seat and the upper cover from bottom to top; the boss plays a positioning role, which facilitates the plug-in cooperation between the adapter plug and the external original plug.

[0014] Specifically, the mounting seat is further provided with a positioning hole, and a positioning column is provided at the bottom of the upper cover corresponding to the positioning hole, and the positioning column extends downward into the positioning hole; the positioning column cooperates with the positioning hole to position the installation position of the upper cover on the mounting seat, thereby facilitating the installation operation of the upper cover on the installation cavity.

[0015] The beneficial effects of the utility model are as follows:

[0016] (1) This adapter plug with elastic anti-dropping piece has an elastic anti-dropping piece on the installation cavity. When the adapter plug is connected to the original plug, the pin on the original plug passes through the plug-in through hole and the elastic anti-dropping hole to connect with the other end of the conductive terminal. The pin on the original plug will be clamped by the elastic anti-dropping piece, ensuring that the connection between the pin on the original plug and the conductive terminal is firm, making it difficult for the adapter plug to loosen due to external force, thereby improving the safety of electrical equipment and the life of the equipment.

[0017] (2) When the pin of the original plug is inserted into the elastic anti-drop hole, it pushes the elastic clamping part to undergo elastic deformation, thereby causing the pin of the original plug to elastically abut against multiple elastic clamping parts, thereby improving the connection firmness.

[0018] (3) The elastic clamping portion is gradually curved downward from the outer side of the elastic anti-dropout part toward the elastic anti-dropout hole, which makes it easier for the pin of the original plug to be inserted into the elastic anti-dropout hole by pushing the elastic clamping portion, and also makes it difficult for the pin of the original plug to be disengaged after being inserted into the elastic anti-dropout hole.
