DETAILED DESCRIPTION

[0040] 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.

[0041] Embodiment 1.

[0042] See also Figure 1-Figure 7, a combination socket of the present embodiment includes an outer packaging body 1 and a socket body 2, the outer packaging body 1 is a hollow structure, and the socket body 2 is provided with two rotating shaft bodies 21 which are arranged symmetrically with respect to the socket body 2, and the socket body 2 is rotatably connected to the cavity of the outer packaging body 1 through the rotating shaft bodies 21 and is driven by an external force to rotate relative to the outer packaging body 1, and a three-hole socket 22 and a two-hole socket 23 are provided on the socket body 2, and a power terminal unit 3 is provided on the socket body 2, and a power spring unit 4 matched with the power terminal unit 3 is provided on the outer packaging body 1, and a through hole 11 for completely exposing the three-hole socket 22 or the two-hole socket 23 is opened on the outer packaging body 1, and when the three-hole socket 22 or the two-hole socket 23 is completely exposed on the outer packaging body 1, it realizes electrical connection with an external power supply through the power terminal unit 3 and the power spring unit 4.

[0043] In this embodiment, the three-hole socket 22 and the two-hole socket 23 are respectively located on two parallel sides of the socket body 2. In addition to this arrangement, the three-hole socket 22 and the two-hole socket 23 can also be arranged to be respectively located on two angled sides of the socket body 2 (such as Figure 6 As shown in , the angle between the two side surfaces may be 60°).

[0044] See also Figure 2-Figure 5 The power terminal unit 3 includes a positive terminal 31, a negative terminal 32 and a grounding terminal 33. A grounding spring 12 is provided on the outer packaging body 1. The grounding spring 12 is located on the rotation track of the grounding terminal 33. The power connecting spring unit 4 includes a positive spring 41 and a negative spring 42. The positive spring 41 is located on the rotation track of the positive terminal 31, and the negative spring 42 is located on the rotation track of the negative terminal 32.

[0045] Among them, the positive terminal 31 is conductively connected to the positive terminals of the three-hole socket 22 and the two-hole socket 23, the negative terminal 32 is conductively connected to the negative terminals of the three-hole socket 22 and the two-hole socket 23, and the grounding terminal 33 is conductively connected to the grounding terminal of the three-hole socket 22.

[0046] Among them, there are two power-connecting spring clip units 4 and two grounding spring clips 12, the positive spring clips 41 of the two power-connecting spring clip units 4 are respectively located at the two ends of the rotation track of the positive terminal 31, the negative spring clips 42 of the two power-connecting spring clip units 4 are respectively located at the two ends of the rotation track of the negative terminal 32, and the two grounding spring clips 12 are respectively located at the two ends of the rotation track of the grounding terminal 33.

[0047] By providing two power connection spring clip units 4, the complexity of the positive and negative pole docking structure between the socket body 2 and the outer packaging body 1 during the switching of the socket usage mode (i.e., switching between the three-hole socket 22 and the two-hole socket 23) is reduced, thereby ensuring the accuracy and stability of the positive and negative pole wiring after the socket usage mode is switched, thereby ensuring the use effect of the socket.

[0048] See also Figure 4 The outer package body 1 is provided with a positive terminal 51, a negative terminal 52 and a grounding terminal 53, which improves the convenience of connecting the wires on the socket.

The driving effect of the driving ring 6 on the socket body 2 through the gear transmission mechanism 61 and the bevel gear transmission mechanism 62 realizes the rotation of the socket body 2 relative to the outer package body 1, reduces the safety risk of directly pushing the socket body 2 by hand to switch the sockets thereon, and improves the safety of the socket.

[0050] Embodiment 2.

[0051] See also Figure 8-Figure 12 The other structures of this embodiment are basically the same as those of the first embodiment, except that the rotation trajectory of the positive terminal 31 and the rotation trajectory of the negative terminal 32 are on the same plane and the diameters of the rotation trajectories of the two are different, and the grounding terminal 33 and the grounding spring 12 are both on the rotation axis between the socket body 2 and the outer packaging body 1 and are rotationally connected and in contact with each other.

[0052] In order to reduce the difficulty of docking between the power terminal unit 3 and the power spring unit 4 on the socket, the negative terminal 32 and the negative spring 42 can be provided one each, and the negative terminal 32 and the negative spring 42 are both located on the rotation axis between the socket body 2 and the outer packaging body 1 and are rotationally connected and in contact with each other, such as Fig.10 , Fig.11 as shown in .

[0053] See also Fig.12The positive terminal 31 and the negative terminal 32 are both slidably arranged on the socket body 2, and a spring 71 is arranged between the positive terminal 31 and the socket body 2 and between the negative terminal 32 and the socket body 2. The two ends of one of the two springs 71 are respectively pressed between the inner end of the positive terminal 31 and the socket body 2, and the two ends of the other spring 71 are respectively pressed between the inner end of the negative terminal 32 and the socket body 2.

Through the structural arrangement of the positive terminal 31 and the negative terminal 32 on the socket body 2 and the arrangement of the corresponding structures on the positive spring sheet 41 and the negative spring sheet 42, the smoothness of the separation and connection between the terminal and the spring sheet is improved during the rotation of the socket body 2 relative to the outer package body 1, and the convenience of switching the socket usage mode is ensured, and the stability of the socket after the mode is switched can also be improved.

[0054] Embodiment three.

[0055] See also Fig.13 , Fig.14 The other structures of this embodiment are basically the same as those of the second embodiment, except that: there is only one power connection spring piece unit 4, the positive terminal 31 and the negative terminal 32 are symmetrically arranged relative to the ground terminal 33, the rotation tracks of the positive terminal 31 and the negative terminal 32 are on the same plane and the diameters of the rotation tracks of the two are the same, and the positive spring piece 41 and the negative spring piece 42 are symmetrically arranged relative to the ground spring piece 12. By setting a single power connection spring piece unit 4, while ensuring the docking effect of the positive and negative electrodes during the switching of the socket use mode, it can also reduce the space occupied by the positive and negative electrode docking structure on the socket, thereby helping to control the volume of the socket and reduce the restrictions on the socket use site.

[0056] After the socket usage mode is switched between the three-hole socket 22 and the two-hole socket 23, the connection between the terminal and the spring sheet will be swapped (i.e., the positive terminal 31 changes from being conductively connected to the positive spring sheet 41 to being conductively connected to the negative spring sheet 42). In order to ensure the safety of the socket after the usage mode is switched, the three-hole socket 22 and the two-hole socket 23 are conductively connected to the power terminal unit 3 in opposite ways, i.e., the positive terminal of the three-hole socket 22 is conductively connected to the positive terminal 31 and the negative terminal thereof is conductively connected to the negative terminal 32, and the positive terminal of the two-hole socket 23 is conductively connected to the negative terminal 32 and the negative terminal thereof is conductively connected to the positive terminal 31, thereby ensuring that the socket is used in the state of positive and negative connection when the three-hole socket 22 is used, and also ensuring that the positive and negative terminals of the socket can be used in the state of positive connection when the two-hole socket 23 is used after switching.

[0057] Embodiment 4.

A conductive spring 81 is provided in the middle position of the two positive springs 41 and in the middle position of the two negative springs 42, thereby ensuring the normal use of multiple usage modes on the socket.

[0059] Among them, the positive end of the USB socket 8 is conductively connected to the positive terminal 31 and the negative end thereof is conductively connected to the negative terminal 32, the conductive spring sheet 81 located between the two positive spring sheets 41 is conductively connected to the positive terminal 51, and the conductive spring sheet 81 located between the two negative spring sheets 42 is conductively connected to the negative terminal 52.

[0060] In order to improve the diversity and application scope of the socket styles, the USB socket 8 can be replaced with a three-hole socket 22 or a two-hole socket 23. At the same time, a Micro-USB interface, a Mini-USB interface, a Type-B interface, a Type-C interface and a Lightning interface, etc. can be added to the USB socket 8. In addition to setting the above interfaces on the USB socket 8, the above interfaces can also be set on the three-hole socket 22 or the two-hole socket 23.
