[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The principle and structure of the present invention will be described in detail below with reference to the drawings and embodiments.

[0023] As shown Figures 1 to 3 in the figure, the present invention provides a connector, comprising: a first terminal 1 and a second terminal 2. The first terminal 1 is connected to a power source, and the second terminal 2 is connected to an electrical appliance. Wherein, a third conductive block 13 communicating with the power source is provided inside the first terminal 1, a first conductive block 11 is provided at the touchable insertion end of the first terminal 1, and the third conductive block 13 is spaced from the first conductive block 11. When the first terminal 1 is inserted into the second terminal 2, the first conductive block 11 contacts and conducts with the second conductive block 22, and when not inserted, the third conductive block 13 is spaced from the first conductive block 11. When the power source is connected to the first terminal and touches the first conductive block at the insertion end of the first terminal, there will be no electric shock, greatly improving safety, and it can be used for engineering wiring.

[0024] In the present invention, a second conductive block 22 is provided on the second terminal 2. After the second conductive block 22 is inserted, it can squeeze the first conductive block 11 to make the first conductive block 11, the second conductive block 22 and the third conductive block 13 contact and connect, so that the first terminal 1 and the second terminal 2 are conducted, and both installation and plugging and unplugging are very simple.

[0025] In a specific embodiment, both the first terminal 1 and the second terminal 2 are tubular with one end closed. The outer diameter of the first terminal corresponds to the inner diameter of the second terminal 2, so that the open end of the first terminal 1 and the open end of the second terminal 2 can be inserted with a bushing to prevent the internal conductive block from leaking out to ensure safety. The first conductive block 11, the second conductive block 22, and the third conductive block 13 are cylindrical. Among them, the third conductive block 13 is fixed on the closed end of the first terminal 1, and the second conductive block 22 is fixed on the closed end of the second terminal 2, and the first, second, and third conductive blocks are coaxially arranged. An elastic member 3 is provided inside the first terminal 1. The elastic member 3 can be a spring. The side surface of the spring is bushed with the inner wall of the first terminal 1 to ensure that it will not deviate during the extrusion process. One end of it is wound around the circumferential surface of the first conductive block 11 and fixed to the first conductive block 11, and the other end is fixed to the closed end of the first terminal 1, so that when the bushing is inserted, the first conductive block 11 can be squeezed by the second conductive block 22 to contact the third conductive block 13, and when pulled out, the third conductive block 13 is reset to be spaced from the first conductive block 11 by the elastic force of the spring, achieving the effect of preventing electric shock.

[0026] A pair of oppositely arranged convex points 14 are provided on the outer circumferential side wall of the first terminal 1, and a card slot 24 extending inward from the open end is provided on the inner wall of the second terminal. The card slot 24 is L-shaped. The convex points 14 slide inward along the card slot 24 to compress the spring. When reaching the L-shaped corner of the card slot 24, the first, second, and third conductive blocks contact and conduct. Rotate the first terminal 1 or the second terminal 2 to make the convex points 14 move in the circumferential direction. At this time, the first terminal 1 and the second terminal 2 are interlocked by elastic force.

[0027] In the present invention, the materials of the first, second, and third conductive blocks are copper.

[0028] The present invention also provides an electrical appliance using the above connector.

[0029] In specific use, when the connector is used to conduct current for an electrical device, the first terminal is connected to the power supply terminal of the device, and when the second terminal is connected to the device or used on the device, the bumps on the outer shell of the first terminal are aligned with the L-shaped card slots on the second terminal, and after being inserted along the vertical card slot, it enters the second terminal; as the length of the first terminal entering the second terminal increases, the third conductive block inside the first terminal contacts the second conductive block of the second terminal. When the first terminal is inserted to the bottom of the vertical card slot of the L-shaped card slot of the second terminal, the first conductive block inside the first terminal contacts the third conductive block. At this time, the first, second, and third conductive blocks are all connected and conduct electricity. At this time, the spring of the first terminal is stressed to the maximum value. Rotate the first terminal clockwise so that it enters the horizontal card slot of the L-shaped card slot. After rotating the first terminal 60° clockwise, it enters the end point of the L-shaped horizontal card slot. Since the spring deforms and presses the first terminal to make the first terminal away from the second terminal, the second terminal is pushed away from the first terminal by the reaction force. The first and second terminals are interlocked under the reaction force of the spring elasticity. At this time, the bumps and card slots of the first and second terminals are stressed to prevent loosening, and the first and second terminals are internally connected to conduct current.

[0030] When the electrical device needs to be powered off, it can be directly rotated counterclockwise by 60° to disconnect the powered device. The first and second terminals naturally bounce open under the action of the elastic force. After disconnection, the first conductive block inside the first terminal connected to the power supply deforms under the action of the spring and moves away from the third conductive block, and the inside of the terminal is disconnected and does not conduct electricity, which can avoid electric shock when touching the terminal when the power supply is connected.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
