DETAILED DESCRIPTION
[0033] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0034] Example 1.
[0035] See also Figure 1 、 Figure 2 , this embodiment provides an electrical connection structure, including a connecting female end 1 and a connecting male end 2, any or all of the connecting female end 1 and the connecting male end 2 are arranged on the socket, and the connecting female end 1 and the connecting male end 2 both include a connecting base 3, and three electrode heads 31 are provided on the end surface of the connecting base 3, which are respectively electrically connected to the live wire end, the neutral wire end and the ground wire end of the socket. The three electrode heads 31 are arranged at equal angles around the central axis of the connecting base 3, and the corresponding electrode heads 31 on the connecting female end 1 and the connecting male end 2 can be magnetically connected.
[0036] When the female connection end 1 and the male connection end 2 are docked, the corresponding electrode heads 31 on the female connection end 1 and the male connection end 2 are close to each other and attracted together by their own strong magnetism, thereby completing the physical connection between the female connection end 1 and the male connection end 2 while also completing the electrical connection between the corresponding electrode heads 31 on the two.
[0037] In this embodiment, the end face of the electrode head 31 on the connecting female end 1 is a concave spherical shape 32, and the end face of the electrode head 31 on the connecting male end 2 is a convex spherical shape 33. Therefore, when the connecting female end 1 and the connecting male end 2 are docked, the shape matching between the electrode heads 31 on the two can guide the connecting female end 1 and the connecting male end 2 to dock, thereby improving the convenience of the docking operation.
[0038] See also Figure 1 、 Figure 2 Two push-to-reset switches 4 are provided between the live wire end and the corresponding electrode head 31 on the connecting female end 1. When the connecting female end 1 is docked with the connecting male end 2, the pressing end 41 of the push-to-reset switch 4 is located on the moving track of the connecting seat 3 on the connecting male end 2.
[0039] Among them, the connecting base 3 of the connecting female end 1 and the connecting male end 2 are both fixedly connected to the socket, and a groove 51 for inserting the connecting base 3 of the connecting male end 2 is provided on the connecting base 3 of the connecting female end 1, and slots 52 connected to the groove 51 are provided at two opposite positions on the connecting base 3 of the connecting female end 1, and an insert block 53 adapted to the slot 52 is provided on the connecting base 3 of the connecting male end 2, and the pressing end 41 passes through the connecting base 3 and is located in the slot 52, and the moving direction of the pressing end 41 is on the same straight line as the insertion direction of the corresponding insert block 53.
[0040] When the female end 1 and the male end 2 are docked, the two connecting seats 3 are close to each other, so that the connecting seat 3 of the male end 2 enters the groove 51 and the plug block 53 is gradually inserted into the corresponding slot 52. In this process, the pressing end 41 will be pushed by the plug block 53 and slide relative to the press reset switch 4 and withdraw from the slot 52, thereby realizing the pressing operation of the press reset switch 4, so that the press reset switch 4 changes from the open state to the closed state and the reset spring thereon is in a compressed state. The electrode head 31 on the female end 1 is electrically connected to the live wire end on the socket, and when the two connecting seats 3 are against each other, the corresponding electrode heads 31 on the two connecting seats 3 are in contact with each other and electrically connected while being magnetically connected, achieving the effect of completing the physical connection between the female end 1 and the male end 2 while also completing the electrical connection between the two sockets, thereby achieving the purpose of the two sockets being able to be connected in series and used in combination, and at the same time reducing the safety risk of electric shock caused by the electrode head 31 on the female end 1 being energized due to the press reset switch 4 being pressed accidentally.
[0041] When the connection between the female end 1 and the male end 2 needs to be released, the male end 2 is pulled away from the female end 1, so that the plug 53 is moved out of the slot 52, thereby releasing the reset restriction of the pressing end 41, so that the pressing end 41 can pop out and reset under the force of the reset spring in the reset switch 4 to restore its original state (that is, the pressing end 41 re-extends into the slot 52), and the electrical connection between the electrode head 31 on the female end 1 and the live wire end on the socket is disconnected, thereby reducing the safety risk caused by the exposure of the electrode head 31 on the female end 1 when the socket is used.
[0042] In this embodiment, the electrode head 31, the two push-to-reset switches 4 and the live wire end are connected in series through wires, so that the electrode head 31 and the live wire end can only be connected when the two push-to-reset switches 4 are in a closed state, which improves the safety of use and reduces the risk of leakage.
[0043] Example 2.
[0044] See also Figure 3 、 Figure 4 The structure of this embodiment is basically the same as that of the first embodiment, except that: the pressing end 41 passes through the connecting seat 3 and is exposed on the side of the groove 51, and the two pressing ends 41 are arranged at equal angles around the central axis of the groove 51, and the end face of the pressing end 41 is spherical 42 and its moving direction is perpendicular to the insertion direction of the connecting seat 3 of the connecting male end 2.
[0045] When the female connector 1 and the male connector 2 are docked, as the connector base 3 of the male connector 2 is inserted into the groove 51, the connector base 3 will press against the pressing end 41 and push it out of the groove 51 (i.e., press the reset switch 4), causing the reset switch 4 to change from an open state to a closed state and the reset spring therein to be compressed. At this time, the electrode head 31 on the female connector 1 and the live wire end on the socket are electrically connected. When the two connector bases 3 are pressed against each other, the female connector 1 and the male connector 2 are physically connected under the action of magnetic attraction, and at the same time, the corresponding electrode heads 31 on the two connector bases 3 contact each other to complete the electrical connection.
[0046] Example 3.
[0047] See also Figure 5-Figure 7 The structure of this embodiment is basically the same as that of the second embodiment, except that: a rotating disk 6 is rotatably connected to the connecting seat 3 of the connecting female end 1, and the rotating disk 6 is located in the groove 51 and is driven by an external force to rotate relative to the connecting seat 3. A through hole 61 corresponding to the electrode head 31 is opened on the rotating disk 6, and a torsion spring is provided between the rotating disk 6 and the connecting seat 3. When the connecting female end 1 is docked with the connecting male end 2, the through hole 61 is located between the adjacent electrode heads 31 on the connecting female end 1 and can be located on the moving trajectory of the corresponding electrode head 31 on the connecting male end 2.
[0048] Among them, two relative positions on the connecting seat 3 of the connecting male end 2 are provided with protrusions 71, and the connecting seat 3 of the connecting female end 1 is provided with a first sliding groove 72 for allowing the protrusion 71 to slide along the direction of the connecting seat 3 of the connecting male end 2 to be inserted into the groove 51, and a second sliding groove 73 for allowing the protrusion 71 to rotate a certain angle along the circumference of the groove 51. The first sliding groove 72 and the second sliding groove 73 are connected and both are connected to the groove 51.
[0049] When the protrusion 71 on the connecting male end 2 moves along the first sliding groove 72 to guide the connecting female end 1 and the connecting male end 2 to dock, in the process of inserting the connecting base 3 of the connecting male end 2 into the groove 51, while the connecting base 3 of the connecting male end 2 presses the press reset switch 4, the electrode head 31 on the connecting male end 2 will also gradually be inserted into the through hole 61. After the connecting base 3 is inserted into the groove 51, the connecting female end 1 and the connecting male end 2 rotate relative to each other, so that the protrusion 71 enters the second sliding groove 73 from the first sliding groove 72 and slides along it until the rotating disk 6 is driven by the connecting base 3 of the connecting male end 2 to rotate 60° relative to the connecting base 3 of the connecting female end 1. At this time, the through hole 61 on the rotating disk 6 overlaps with the corresponding electrode head 31 on the connecting female end 1, so that the electrode head 31 on the connecting male end 2 in the through hole 61 can contact the electrode head 31 on the connecting female end 1, thereby realizing the effect of electrical connection between the two sockets, and at the same time, the connecting female end 1 and the connecting male end 2 are physically connected through the magnetic connection between the electrode heads 31.
[0050] When the connection between the female end 1 and the male end 2 is released, the female end 1 and the male end 2 rotate relative to each other, so that the protrusion 71 enters the first slot 72 from the second slot 73. At this time, the female end 1 and the male end 2 release the magnetic connection and the electrical connection between the two sockets is also released. At this time, the through hole 61 is located between adjacent electrode heads 31, reducing the safety risk of the electrode head 31 on the female end 1 being exposed when the socket is in use. Subsequently, the male end 2 is pulled away from the female end 1, so that the connection seat 3 is moved out of the groove 51 and the electrode head 31 on the male end 2 is also moved out of the through hole 61, so that the pressing end 41 is reset and re-enters the groove 51. At this time, the electrical connection between the electrode head 31 of the female end 1 and the live wire end is disconnected, further ensuring the safety of the socket.
[0051] When the male end 2 is not connected to the connecting female end 1, in order to ensure the stability of the relative position between the rotating disk 6 and the connecting base 3 of the connecting female end 1, a round head pin corresponding to the through hole 61 can be slidably connected to the connecting base 3, and a spring is provided between the inner end of the round head pin and the connecting base 3, and the two ends of the spring are respectively pressed against the round head pin and the connecting base 3. The round head pin is located between the adjacent electrode heads 31 on the connecting base 3, so that when the male end 2 is not connected to the connecting female end 1, the outer end of the round head pin can be inserted into the corresponding through hole 61, which plays a role in limiting the rotation of the rotating disk 6, so that the rotating disk 6 and the connecting base 3 are in a relatively fixed state.
[0052] When the male end 2 and the female end 1 are docked, the electrode head 31 of the male end 2 can push the round head pin out of the through hole 61 during the process of being inserted into the through hole 61. At this time, the spring is compressed, and the restriction on the rotation of the rotating disk 6 relative to the connecting seat 3 is released, so that the rotating disk 6 can rotate relative to the connecting seat 3. At the same time, the rotating disk 6 also plays a role in restricting the round head pin from resetting.
[0053] Example 4.
[0054] See also Figure 8 The structure of this embodiment is basically the same as that of the third embodiment, the difference being that the pressing end 41 passes through the connecting seat 3 and is inserted into the through hole 61, the end face of the pressing end 41 is spherical 42 and its moving direction is parallel to the insertion direction of the connecting seat 3 of the connecting male end 2.
[0055] During the process of inserting the connecting seat 3 of the connecting male end 2 into the groove 51, the electrode head 31 on the connecting male end 2 will gradually extend into the through hole 61, thereby pushing the pressing end 41 in the through hole 61, so that the pressing end 41 slides relative to the press reset switch 4, thereby completing the electrical connection between the electrode head 31 on the connecting female end 1 and the live wire end on the socket by pressing the press reset switch 4, and then realizing the electrical connection between the corresponding electrode heads 31 on the connecting male end 2 and the connecting female end 1 and the physical connection between the connecting male end 2 and the connecting female end 1 by magnetic attraction by relative rotation between the connecting male end 2 and the connecting female end 1.
[0056] In this embodiment, three push-to-reset switches 4 may be provided, thereby ensuring a harmonious visual appearance of the female connector 1 .
[0057] Example 5.
[0058] See also Figure 9 In this embodiment, a socket includes a power connection unit 91 and several extension units 92. The power connection unit 91 is connected to an external power source through a power cord 93 with a plug. The extension units 92 are connected and arranged in sequence. The power connection unit 91 and the extension units 92 are both provided with one or more of a two-hole socket, a three-hole socket, and a USB socket (such as a Micro-USB interface, a Mini-USB interface, a Type-B interface, a Type-C interface, and a Lightning interface, etc.). The power cord 93 and the power connection unit 91, the power connection unit 91 and the extension units 92, and adjacent extension units 92 can be connected through any one of the electrical connection structures described in any one of Embodiments 1 to 4.
[0059] In this embodiment, there are two ways to set the connection male end 2 and the connection female end 1 between the power cord 93, the power connection unit 91 and the extension unit 92:
[0060] (1) The power cord 93 is provided with only a connecting male end 2, the power connection unit 91 is provided with two connecting female ends 1, and the expansion unit 92 is provided with a connecting male end 2 and a connecting female end 1;
[0061] (2) The power cord 93 is only provided with a connecting female end 1 , and both the power connection unit 91 and the expansion unit 92 are provided with a connecting male end 2 and a connecting female end 1 .
[0062] In addition to the above-mentioned setting method, more connecting female ends 1 can be provided on the power connection unit 91, so that the power connection unit 91 can be connected to the expansion unit 92 in multiple horizontal directions for expanded use of the socket strip. At the same time, multiple connecting female ends 1 can also be provided on the expansion unit 92 to further improve the flexibility of combined use, thereby reducing the restrictions on combined use caused by the socket strip placement area.
[0063] Both the power receiving unit 91 and the extension unit 92 can be connected to the power cord 93 separately and connected to an external power source through the power cord 93 to be used separately as a power strip. When multiple devices need to be powered, the user can select the corresponding number and type of extension units 92 and the power receiving unit 91 according to the number of devices and the type of plugs on them, or the extension units 92 can be connected in sequence by connecting the male end 2 and the female end 1 to form a power strip for use. This not only meets the needs of different users for the use of the power strip, but also ensures the utilization rate of the sockets on the power strip, improves the flexibility of use and reduces the cost of use.
