It will be readily understood by those skilled in the art that these drawings are merely illustrative of the piping and are not intended to limit the scope of protection of this invention.

Figure 8 A front view of the second position of the core component according to an embodiment is shown. Figure 9 A control circuit diagram according to an embodiment is shown; and Figure 10 and Figure 11 A control flowchart according to an embodiment is shown. Detailed Implementation

[0029] refer to Figures 1 to 4 A replaceable socket according to an embodiment of the present invention is described, comprising: a substrate 100 and core members 200, 300. The substrate 100 includes: a control unit (not shown) and a recess 10 for mounting the core member. The recess 10 may be formed on a panel 13, and the control unit may, for example, be disposed on the back side of the panel 13, making the control unit difficult to access after installation, or the control unit may be disposed on the front side of the panel 13. The recess 10 of the substrate includes: one or more electrical terminals 11 and a first sensor 121 and a second sensor 122. (Reference) Figure 1 and Figure 2 According to this embodiment, the groove 10 includes a first sensor 121, a second sensor 122, and three electrical terminals 11 (located on the left, right, and bottom, respectively). In an alternative embodiment, the number and position of the electrical terminals 11 and the sensors 12 can be varied. The core component 200 includes: a front end face 201 having a connector 22, one or more electrical contacts 21 (e.g., formed as resilient contacts) electrically connected to the connector 22, and a sensed unit 24 that can be sensed by the first sensor 121 and the second sensor 122 when approaching or contacting them. Figure 3The connector 22 on the front end face 201 of the core component 200 can be any type of connector, such as a three-port connector, a two-port connector, a USB connector, or a multi-purpose connector. The front end face 201 of the core component 200 may include a single connector or multiple connectors, such as combinations of similar or different types of the above connectors or other connectors. After the core component 200 is inserted into the groove 10 in the substrate 100 and installed in place, one or more electrical terminals 11 are electrically connected to one or more corresponding electrical contacts 21. The control unit controls the power supply to one or more electrical terminals 11 based on signals sensed by the first sensor 121 and the second sensor 122, thereby achieving safe power supply to the connector through a transmission method from electrical terminals to electrical contacts to the connector. One advantage of the core component in the embodiments of the present invention is that it is not energized during disassembly and installation, and can be safely replaced by the user without the need for professional operation. Therefore, the embodiments of the present invention achieve the purpose of easily replacing the connector according to actual needs or in case of failure.

[0030] In the illustrated embodiment, the groove 10 of the substrate is cylindrical, having an inner circumferential sidewall 101 and a bottom wall 102. Correspondingly, the core member 200 includes a front end face 201 and a cylindrical core member body, the core member body having an outer circumferential sidewall 202 and a bottom wall 203. In alternative embodiments, the shapes of the groove of the substrate and the core member body of the core member can be arbitrarily selected, for example, they can be formed as a cube, cuboid, etc.

[0031] In the illustrated embodiment, the first sensor and the second sensor are disposed on the bottom wall of the groove, while the electrical terminals are disposed on the inner circumferential side wall of the groove. In an alternative embodiment, the first sensor and the second sensor may also be disposed on the side wall of the groove, while one or more electrical terminals are disposed on the bottom wall of the groove. The sensed unit and electrical contacts on the core component may also be adjusted accordingly based on the arrangement within the groove.

[0032] In some embodiments, the first sensor 121 and the second sensor 122 may include any type of proximity sensor or contact sensor. In some embodiments, the first sensor and the second sensor include a magnetic sensor, and the sensed unit 24 includes a magnet. In some embodiments, the first sensor and the second sensor include a radio frequency sensor, and the sensed unit 24 includes a radio frequency chip. In this case, the first signal and the second signal may also include other information, such as the model number of the core component, identification code, etc. The control unit can implement other types of control based on this information, such as the model number of the core component, etc., such as timed power supply, current control, and other intelligent control.

[0033] Continue to refer to Figures 5 to 8 In some embodiments, the recess 10 of the substrate includes a first sensor 121 and a second sensor 122, and the core component is... Figure 5The first position shown is inserted into the groove, causing the first sensor 121 to sense the sensed unit 24 and send a first signal to the control unit. The core component can then move from the first position within the groove. Figure 8 The second position shown is in which one or more electrical terminals 11 are electrically connected to the corresponding one or more electrical contacts 21, and a second sensor 122 senses the sensed unit 24 and sends a second signal to the control unit, which controls the supply of power to the one or more electrical terminals based on the first and second signals. This arrangement provides further improved security, including: the first signal indicating that the core member is accurately inserted into the recess, and the second signal indicating that the core member is accurately moved into place. In the illustrated embodiment, the core member moves from the first position to the second position by rotation, but in alternative embodiments, the core member can also move from the first position to the second position by other means of movement. For example, the core member can switch from the first position to the second position by a guided translation of a short distance in a recess in the substrate. In such an embodiment, the recess will have a relatively large size that allows the core member to translate, and the end plate of the core member can be used to cover the recess with the larger size. For example, in embodiments where the recess is designed as a long strip and the core member has multiple side-by-side connectors, the translational switching operation may be advantageous.

[0034] In some embodiments, the recess 10 of the substrate 100 and the core member 200 include corresponding limiting members to guide the movement of the core member in the recess of the substrate, and / or the recess of the substrate and the core member include locking members to lock the core member after it has moved into place in the recess of the substrate. For example, in the illustrated embodiment, reference is made to... Figure 3 and Figure 6 The core component may include an arcuate groove 25 to engage with a boss 14 on the bottom wall of the recess 10. As the core component rotates from a first position to a second position, the boss 14 engages with the arcuate groove 25 to guide the movement of the core component. The boss 14 and the arcuate groove 25 together also define the first position of the core component during insertion, serving a foolproof function; that is, if the core component is inserted into the recess at an incorrect angle, the core component will not be able to be inserted to the bottom of the recess due to interference between the boss 14 and other positions on the bottom wall of the core component. (Continue to the previous section) Figure 4 and Figure 7 The core component further includes a slot 26 extending a certain height from the bottom wall of the core component along the side wall, and a locking protrusion 261 at the bottom of one end of the slot. The inner circumferential side wall of the groove 12 includes a corresponding latching block 15 defining a slot. When the core component rotates from a first position to a second position, the locking protrusion 261 on the core component engages with the latching block 15 of the groove and engages in the slot, thereby locking the core component from axially disengaging from the groove. In some embodiments, the slot 26 on the side wall of the core component extends between two electrical contacts 21 to avoid contact with electrical contacts on the side.

[0035] In some embodiments, a first sensor 121 and a second sensor 122 are spaced apart on the bottom wall 102 of the groove 10, the spacing angle corresponding to the angle at which the core member rotates from a first position to a second position. Furthermore, when the core member performs other movements, the first sensor 121 and the second sensor 122 correspond to the start and end points of the motion trajectory of the sensed unit on the core member. A plurality of electrical terminals 11 are distributed on the inner circumferential sidewall 101 of the groove 10, a boss 14 serves as a limiting member on the bottom wall 102 of the groove, and a slot serves as a locking member on the inner circumferential sidewall 101 of the groove. The outer circumferential sidewall 202 of the core component is provided with a plurality of electrical contacts 21. The bottom wall of the core component is provided with a sensing unit 24 and an arc-shaped groove 25 for engaging with the boss 14 on the bottom wall of the groove. The sidewall 202 of the core component 200 is provided with a locking protrusion 261 that can be engaged in the groove of the inner circumferential sidewall of the groove. When the core component is inserted into the groove of the substrate and is in the first position, the sensing unit 24 contacts or approaches the first sensor 121. The core component can rotate from the first position to the second position in the groove. During the rotation of the core component from the first position to the second position, the boss 14 on the bottom wall of the groove engages with the arc-shaped groove 25 of the core component to guide the movement of the core component. In the second position, the sensing unit 24 contacts or approaches the second sensor 122. The locking protrusion 261 of the core component is engaged in the groove in the groove, and one or more electrical terminals 11 are electrically connected to one or more corresponding electrical contacts 21. In the illustrated embodiment, the electrical contact 21 may be composed of a metal spring, and the electrical terminal 11 may be disposed in a shallow groove. In the second position, the elastic spring 21 extends into the shallow groove of the electrical terminal 11, and the two remain in contact due to the elastic force. It should be understood that other forms of cooperating limiting and / or locking components may be included between the groove and the core member, including but not limited to, various forms of raised groove fits, geometric feature fits, wedges, threads, snaps, magnetic attraction, etc. In some embodiments, a seal may be provided between the core member and the groove to prevent dust and the like from entering from the gap.

[0036] In some embodiments, the second sensor 122 continuously detects the sensed unit 24 at a certain frequency and sends a second signal to the control unit. The control unit supplies power to one or more electrical terminals 11 after detecting the first signal once and the second signal twice in sequence. This configuration provides better security. In some embodiments, the control unit is configured to continuously detect the presence of the second signal while supplying power to one or more electrical terminals 11, and cut off the power supply to one or more electrical terminals 11 when the second signal disappears. This interrupts the power supply to one or more electrical terminals 11 once the core component is changed in position, ensuring the safety of the core component when it is tampered with or during core component replacement. In some embodiments, the core component can be removed by rotating it back to the first orientation. In some embodiments, the end face may be provided with a pry bar 23 to facilitate the use of a flat object such as a screwdriver to assist in removing the core component from the groove in the first position.

[0037] According to another aspect of the invention, substrates and core components according to various embodiments of the invention are also provided. The substrates and core components can be sold together as a kit, for example, a kit may include multiple substrates and multiple core components, which can be assembled by the user as needed; alternatively, the substrates and core components can be sold separately as accessories.

[0038] Continue to refer to Figure 9 The diagram illustrates a circuit diagram of a control unit according to an embodiment of the present invention. A first sensor 121 and a second sensor 122 provide signals to a microcontroller (MCU) 90. The MCU executes logic control and, when a condition is met, activates the circuit containing relay 91. Once activated, relay 91 pulls the power supply switches 93, 94 of one or more electrical terminals 11 to the closed position, thereby supplying power to one or more electrical terminals 11. It should be understood that... Figure 9 The circuit diagrams shown are for illustrative purposes only. In alternative embodiments, the control circuitry may be modified as needed to achieve the same or similar control objectives.

[0039] Continue to refer to Figure 10 It illustrates a control logic flowchart of a microcontroller 90 according to one embodiment, including the following steps: Initialize the relay. Determine if there is a signal input from the first sensor. If not, continue with this step; if there is, proceed to the next step. Determine if there is a signal input from the second sensor. If not, continue with this step; if there is, proceed to the next step. Determine if the second sensor has a delayed signal input. If not, continue with this step; if so, turn on the relay.

[0040] Continue to refer to Figure 11It illustrates a power-off control logic according to an embodiment of the present invention, including the following steps: Initialize the relay. Determine if the second sensor has a continuous signal input. If it does, continue with this step. If not, turn off the relay and cut off the power supply to the electrical terminals. Determine if there is a signal input from the first sensor. If not, continue with this step. If there is a signal, wait for the first sensor signal to disappear, then reset the system and wait for the next first sensor signal.

[0041] Therefore, the present invention also provides a power supply control method for a replaceable socket, the method comprising: Receive the first signal sent by the first sensor; Receive the second signal sent by the second sensor; and Power is supplied to one or more electrical terminals of the substrate based on the first signal and the second signal.

[0042] In some embodiments, the control unit of the replaceable socket can be powered by the mains. In the event of an unexpected power outage (e.g., due to a circuit breaker trip), the control unit retains its state before the power outage. If it was supplying power to one or more electrical terminals before the power outage, it directly checks for the presence of the second signal after power is restored. If the signal is present, it continues to supply power to the one or more electrical terminals; otherwise, it disconnects the power supply. If it was in an idle state waiting for the first signal before the power outage, it remains in an idle state after power is restored. Furthermore, if the core component was removed during the power outage, and the second signal is not detected after power is restored, the power supply to the one or more electrical terminals is directly disconnected. In an alternative embodiment, the replaceable socket may have its own battery to ensure power supply to the control unit.

[0043] The specific embodiments described above are merely for the purpose of more clearly illustrating the principles of the present invention, wherein the various components are clearly shown or described to make the principles of the present invention easier to understand. Various modifications or variations can be readily made to the present invention by those skilled in the art without departing from the scope of the invention. Therefore, it should be understood that all such modifications or variations should be included within the patent protection scope of the present invention.
