[0002] In the patent "A Microphone Compatible with PogoPin and Type-c Charging (CN202322684000.5)", the scenario of single-loop PogoPin charging is as Figure 1 , although this patent uses a conversion circuit to achieve single-loop charging without the need to distinguish between positive and negative poles and is compatible with Type-c wired power supply. The defects of the above prior art are as follows: In power supply, traditional PogoPin power supply uses 2 fixed charging thimbles for charging. When the position of the powered device rotates, there is a situation where power supply cannot be achieved, as shown in Figure 2 . This problem is a design defect of the single-loop PogoPin, and as the distance between the two semi-circular rings increases, the probability of not being able to supply power also increases. The present utility model improves the shape of the copper ring to achieve 360-degree power supply for this problem. Summary of the Utility Model

The PogoPin connector head includes four power supply thimbles, and two of the power supply thimbles are used to contact the two semi-ring electrodes correspondingly to achieve power supply. When these two power supply thimbles are within the opening gap, the other two power supply thimbles contact the two sub-electrodes correspondingly to achieve power supply.

[0023] The following further elaborates on this application Figures 3 - 7 in conjunction with the accompanying drawings.

[0024] The embodiments of this application disclose a PogoPin connector and a PogoPin power supply device.

[0025] Referring to Figure 3 , the PogoPin connector includes a PogoPin socket and a PogoPin connector head. A PogoPin contact ring is provided on the PogoPin socket, generally a copper electrode. The PogoPin contact ring includes two half-ring electrodes 1. An opening gap 2 is provided between the two ends of the two half-ring electrodes 1. The PogoPin contact ring further includes two sub-electrodes 3. The two sub-electrodes 3 are electrically connected to the two half-ring electrodes 1 respectively. The PogoPin connector head includes four power supply thimbles, and the power supply thimbles are point contacts such as spring pins, copper columns or other structures. Two of the power supply thimbles are used to contact the two half-ring electrodes 1 correspondingly to achieve power supply. When these two power supply thimbles are within the opening gap 2, the other two power supply thimbles contact the two sub-electrodes 3 correspondingly to achieve power supply.

[0026] The two sub-electrodes 3 are respectively arranged in the radial extension directions outside the two opening gaps 2, which can facilitate the other two power supply thimbles to quickly transition to contact the two sub-electrodes 3 when the two power supply thimbles are within the opening gap 2.

[0027] The central angle of the opening gap 2 falls within the central angle of the sub-electrode 3, and the distance of the opening gap 2 is less than the width of the sub-electrode 3, ensuring that the sub-electrode 3 can make up for the charging angle vacant by the opening gap 2.

[0028] The two sub-electrodes 3 and the two half-ring electrodes 1 are respectively located on two concentric circles. The four power supply thimbles are divided into two inner thimbles 6 and two outer thimbles 7. The two inner thimbles 6 and the two outer thimbles 7 are used to contact the sub-electrodes 3 or the half-ring electrodes 1 on the two concentric circles respectively. The PogoPin contact ring is composed of two co-circular half-ring electrodes and two co-circular sub-electrodes. The half-ring electrode and the sub-electrode share a common center. Such a configuration enables the power supply to transmit current at any position on the ring because they are co-centric. The four needles of the power supply can be inserted into any position of the copper ring to achieve 360-degree power supply. This design eliminates the need for a specific direction and improves the convenience for users. As shown in the accompanying drawings Figure 4As shown, when the outer ejector pin is outside the gap, power is supplied by two outer ejector pins and two half-ring electrodes on the outside; when the outer ejector pin is inside the gap, power is supplied by two inner ejector pins and two sub-electrodes on the inside, solving the problem that the power supply copper column cannot supply power at the two gaps, that is, realizing power supply in all 360 degrees.

[0029] The two sub-electrodes 3 are located inside the two half-ring electrodes 1. It can save the external area of the connector, making the entire power connection base more compact. This is very useful for application scenarios with limited space, such as portable devices or compact electronic devices. The sub-electrodes 3 arranged inside can reduce material usage while improving the rigidity and durability of the overall structure. Since the sub-electrodes 3 are surrounded by the half-ring electrodes 1, this design also helps to enhance the ability to resist physical damage.

[0030] The two inner ejector pins 6 and the two outer ejector pins 7 are distributed on the same straight line passing through the center of the circle. This symmetrical layout can provide structural balance, enabling the power supply to maintain consistent contact pressure and electrical connection quality regardless of the insertion direction. The inner ejector pins 6 and the outer ejector pins 7 with the same polarity are located at the same end of the straight line. Since the ejector pins with the same polarity are at the same end, the power automatic switching circuit can more simply determine the power flow direction based on the position of the ejector pins, thus achieving fast and accurate power switching.

[0031] The two half-ring electrodes 1 are left-right symmetrical and up-down symmetrical structures, and the two sub-electrodes 3 are centrosymmetric structures. For users, the symmetrically designed power connection base means there is no need to worry about the insertion direction of the power supply, providing greater convenience and flexibility. This design eliminates the need for a specific direction, making the power supply process more intuitive and user-friendly. The symmetric design ensures the contact stability of the PogoPin contact ring in all directions. This symmetry means that regardless of the insertion direction of the power supply, good electrical contact can be guaranteed, thus realizing the ability to supply power in all 360 degrees. The symmetric structure also simplifies the manufacturing and assembly processes, can reduce the number of unique components required in the manufacturing process, and there is no need to distinguish the direction of the components during assembly, which helps to improve production efficiency and reduce costs.

[0032] The central angle of the half-ring electrode 1 is larger than that of the sub-electrode 3. The half-ring electrodes 1 have a larger central angle and occupy a larger space in the power connection base, which is convenient for frequent contact and use, thereby improving the current transmission efficiency and reducing resistance. The half-ring electrodes 1 can carry a larger current. This is very important for application scenarios that require high-current power supply, such as fast charging technology. The large area of the half-ring electrodes 1 helps to better dissipate heat and reduce the risk of overheating. The width of the half-ring electrodes 1 is also larger than that of the sub-electrodes 3, and the resistance can be different. The different central angles and resistances of the electrodes can be used to design for helping to identify the polarity, ensuring the correct insertion of the power supply and avoiding incorrect connection.

[0033] A mating gap 4 is provided between the semi-circular electrodes 1 with different polarities. The spacing of the mating gap 4 is smaller than that of the opening gap 2. The smaller mating gap 4 is for optimizing the overall design of the electrical connection base to make it more compact while maintaining the required insulation electrical performance and mechanical strength.

[0034] A conductive connection part 5 is provided between the semi-circular electrode 1 and the sub-electrode 3. They are integrally formed and do not require additional welding or connection steps to ensure electrical connection. The conductive connection part 5 provides a direct electrical connection between the semi-circular electrode 1 and the sub-electrode 3, enabling current to flow between them and ensuring stable transmission of the supply current. As shown in the appendix Figure 5 When the power supply is in the connection part position, any one of the pairs can be selected for power supply, and preferably the outer pair is selected for power supply.

[0035] The conductive connection part 5 is located on the left and right sides of the opening gap 2, connecting the semi-circular electrode 1 and the sub-electrode 3 in the vicinity. The layout of the conductive connection part 5 helps with polarity management, ensuring correct polarity connection and avoiding short circuits or other electrical problems. This helps balance the current path, and this layout also takes safety into account to ensure that during power supply, the conductive connection part 5 will not cause accidental short circuits or overheating due to improper position.

[0036] The design of this application mainly focuses on the design of the copper ring structure and the layout of the thumbtacks. Those skilled in the art can make corresponding thumbtack and circuit structure designs at the charging end and the charged end according to actual needs. The PogoPin connection base provided with the above-mentioned PogoPin contact ring structure can not only be adapted to the connector with four thumbtacks, but also inspire more connector structure and power supply circuit scheme designs. For example, the traditional two power supply thumbtacks can be designed as movable structures. For example, an introduction groove is provided at the interface of the power supply base, and the thumbtack can move radially when inserted, so that they can adapt to different insertion angles and positions to ensure good electrical contact with the electrical connection base. Multiple pairs of switchable power supply structures can also be designed on the power supply. The multiple pairs of switchable power supply structures include multiple pairs of thumbtacks, and these thumbtacks can be switched mechanically or electronically to contact the corresponding positive or negative semi-circular rings. This design provides flexibility and allows the power supply to be compatible with electrical connection bases with different designs.

[0037] The following introduces a charging scenario, as shown in the appendix Figure 6As shown, when the thimble of the positive electrode reaches the half-ring of the negative electrode, the positive and negative electrode loading circuit can reverse the positive and negative electrodes, and the power supply automatic switching circuit can select a pair of outer thimbles outside for power supply; or the power supply automatic switching circuit can select a pair of inner thimbles inside for power supply and make a positive and negative electrode selection. Therefore, the selection of blind insertion of positive and negative electrodes and the power supply switching selection can adjust the sequence according to actual needs. The power supply automatic switching circuit can identify the position state of the thimble through the circuit. When the two outer thimbles are within the opening gap, the two outer thimbles are in an open circuit state. At this time, the two inner thimbles are in a closed state, and they are identified by passing a weak current signal, so that it is known that it is necessary to switch to the pair inside for power supply.

[0038] The following introduces the principle of a thimble power supply circuit. The power supply circuit generally includes a positive and negative electrode loading circuit, and the positive and negative electrode loading circuit is electrically connected to two types of power supply thimbles. The positive and negative electrode loading circuit allows the power supply to automatically detect and determine the polarity when inserted, so as to achieve the correct current flow direction, which belongs to a mature technology in the industry. The two types of power supply thimbles are divided into a positive electrode thimble and a negative electrode thimble, which are used to cooperate with the PogoPin connector for power supply. The positive electrode thimble and the negative electrode thimble in the multi-pair switchable power supply structure each include an inner thimble 6 and an outer thimble 7. The power supply circuit also includes a power supply automatic switching circuit. A pair of inner thimbles 6 and a pair of outer thimbles 7 are respectively electrically connected to the power supply automatic switching circuit, and the power supply automatic switching circuit is electrically connected to the positive and negative electrode loading circuit. The power supply automatic switching circuit is responsible for switching the power supply between different power supply thimbles to ensure that the current always flows to the correct polarity. The above design allows the power supply to ensure that a pair of thimbles is in contact with the corresponding half-ring whether it is the inner circle or the outer circle when contacting the power socket, so as to achieve power supply. Due to the existence of multiple pairs of thimbles and the automatic switching circuit, even if the user does not fully align when inserting the power supply, at least one thimble can be guaranteed to be in contact with the power socket, thus improving the success rate of power supply. This automatic switching mechanism improves the reliability and convenience of power supply.

[0039] As shown in the Figure 7 circuit diagram shown, although only the circuit connection of three charging thimbles is shown, the number of charging thimbles can be repeatedly increased according to needs. The power supply process of this circuit is as follows:

[0040] 1. Copper column state detection: First, use the IO port of the MCU and use the matrix scanning method to detect whether the copper columns are connected to each other. Suppose the IO port of the No. 1 copper column outputs a high level, and then respectively detect whether the IO of the No. 2 and No. 3 copper columns is a high level. If it is a high level, it means it is connected to the No. 1; similarly, detect the states of the No. 2, No. 3, No. 4, etc. copper columns in turn, and the MCU can know the state of the copper columns.

[0041] 2. Load the electrode: After detecting the state of the copper column and knowing the state, it is only necessary to load the positive and negative electrodes on the copper columns on the corresponding copper rings.

[0042] 3. Protection feedback: After charging is achieved, there may be a change in the charging angle, resulting in a short circuit of the electrodes. At this time, the protection module becomes effective (the protection module can be in the form of an OCP, a reset chip, etc.), outputs a feedback signal to the MCU, and the MCU cuts off the power supply and re-detects the status of the copper column to resume charging.

[0043] This specification and the drawings are only exemplary descriptions of the present application and are considered to cover any and all modifications, variations, combinations, or equivalents within the scope of the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the present application and its equivalent technologies, the present application is intended to include these changes and modifications.
