Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen concentrators, and in particular to a DC base structure for easy replacement of oxygen concentrators. Background Technology
[0002] Portable oxygen concentrators are small devices designed for users who need oxygen therapy. With their portability, ease of use, and stability, they provide great convenience to users, especially those who need long-term oxygen therapy or outdoor activities, and can significantly improve their quality of life.
[0003] Most existing portable oxygen concentrators have built-in rechargeable batteries for easy portability. When the rechargeable battery is depleted, the DC power plug of the power adapter needs to be plugged into the DC socket on the oxygen concentrator's mainboard for charging. With prolonged use and frequent charging, users often report that the DC socket on the mainboard is prone to poor connection. In such cases, it is usually necessary to remove the entire mainboard of the oxygen concentrator to replace the DC socket. However, disassembling the mainboard of a portable oxygen concentrator is very troublesome, resulting in a long replacement time and increased replacement cost. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a DC base structure for easy replacement of oxygen generators.
[0005] According to one aspect of the present invention, a conveniently replaceable DC socket structure for an oxygen concentrator is provided, comprising:
[0006] DC Seat;
[0007] The circuit board has a DC socket mounted on it.
[0008] The first connector terminal is located on the circuit board; and
[0009] The second connector is plugged into the first connector, and the second connector has a connector pin that matches the pin hole on the oxygen generator motherboard.
[0010] The DC connector structure of this utility model has a second connector pin that is inserted into a pin hole on the oxygen concentrator's main board. The DC connector connects to the main board of the oxygen concentrator through a circuit board, a first connector, a second connector, and a pin. When the DC connector has a poor connection, simply unplug the pin on the second connector from the pin hole on the main board of the oxygen concentrator, and then re-insert the pin on the new DC connector structure into the pin hole on the main board of the oxygen concentrator to complete the replacement of the DC connector structure. There is no need to disassemble the entire main board of the oxygen concentrator, which is very quick and convenient.
[0011] Furthermore, the first plug terminal has pins on its side, which are soldered onto the circuit board and are flush with the bottom of the first plug terminal.
[0012] Therefore, the first connector achieves circuit connection with the circuit board through the pin. The fact that the pin is flush with the bottom of the first connector ensures that the first connector can be firmly installed on the circuit board and that the first connector will not easily move on the circuit board.
[0013] Furthermore, the first plug terminal is provided with a plug slot, one end of the pin is soldered to the circuit board, and the other end of the pin passes through the first plug terminal and is located in the plug slot. The bottom of the second plug terminal is provided with a plug tab, which is inserted into the plug slot and connected to the pin.
[0014] Therefore, the second plug terminal achieves circuit connection with the pin on the first plug terminal through the plug tab, thereby realizing the connection between the second plug terminal and the DC socket through the first plug terminal, the circuit board, and the DC socket.
[0015] Furthermore, there are four pins, four slots, and four connectors. One end of each of the four pins is soldered to the circuit board, and the other end of each of the four pins passes through the first connector terminal and is located in one of the four slots. Each connector is inserted into one of the four slots, and each connector is connected to one pin.
[0016] Therefore, the first connector can be securely mounted on the circuit board with four pins, and the second connector can be securely mounted on the first connector with four connector tabs and four connector slots. Moreover, the DC socket achieves circuit conduction with the second connector through four pins, four connector tabs and four connector tabs, which can ensure a relatively large input current and guarantee the stability and reliability of the motherboard.
[0017] Furthermore, the four pins are arranged in parallel, the four slots are arranged in parallel, and the four connector pieces are arranged in parallel.
[0018] Therefore, when assembling the second and first plug terminals, simply align the outermost plug tab on the second plug terminal with the outermost plug slot on the first plug terminal, and then press firmly to insert the four plug tabs on the second plug terminal into the four plug slots on the first plug terminal. The assembly of the second and first plug terminals is very simple.
[0019] Furthermore, the connector pin is located on the side of the second connector terminal.
[0020] Therefore, the placement of the connector pin on the second connector terminal facilitates the spatial layout of the DC socket structure within the oxygen generator housing.
[0021] Furthermore, the bottom of the first plug terminal is provided with a protrusion, and the circuit board is provided with a plug hole that matches the protrusion, and the protrusion is inserted into the plug hole.
[0022] Therefore, when assembling the first plug terminal and the circuit board, first insert the protrusion on the first plug terminal into the plug hole on the circuit board to determine the relative position of the first plug terminal and the circuit board. At this time, the pin on the first plug terminal is aligned with the corresponding contact on the circuit board. Then, the pin on the first plug terminal can be directly soldered to the circuit board, thereby improving the efficiency of assembling the first plug terminal and the circuit board.
[0023] Furthermore, there are two protrusions and two insertion holes, with the two protrusions inserted into the two insertion holes respectively.
[0024] Therefore, when assembling the first connector terminal and the circuit board, first insert the two protrusions on the first connector terminal into the two connector holes on the circuit board respectively. At this time, the first connector terminal and the circuit board will not move relative to each other, ensuring that the pins on the first connector terminal are aligned with the corresponding contacts on the circuit board and will not move relative to each other. Then, the pins on the first connector terminal can be directly soldered onto the circuit board, ensuring that the assembly of the first connector terminal and the circuit board is fast and accurate.
[0025] Furthermore, there are four connector pins, arranged in parallel.
[0026] Therefore, the second connector can be securely plugged into the oxygen concentrator motherboard through four connector pins. Moreover, the DC socket connects to the oxygen concentrator motherboard through four pins, four connector pieces, and four connector pins, which can ensure a relatively large input current and guarantee the stability and reliability of the motherboard.
[0027] Furthermore, the connector pins are interference-fitted with the connector holes on the oxygen concentrator's main board.
[0028] Therefore, this ensures that the second connector can be securely installed on the oxygen concentrator's main board, and the connector pins on the second connector will not easily come loose from the main board, thus ensuring the stability of charging the oxygen concentrator.

[0036] See Figures 1 to 4 A DC socket structure for easy replacement of oxygen concentrators includes a DC socket 1, a circuit board 2, a first plug-in terminal 3, and a second plug-in terminal 4.
[0037] See Figure 1 and Figure 2 DC connector 1 is soldered to the bottom of circuit board 2, and the circuits on DC connector 1 are connected to the circuits on circuit board 2.
[0038] The first connector 3 is mounted on the circuit board 2. For details, please refer to [link / reference]. Figure 1 , Figure 3 and Figure 4The first plug terminal 3 has pins 31 mounted on its side. The pins 31 are flush with the bottom of the first plug terminal 3 and are soldered to the top of the circuit board 2. The first plug terminal 3 achieves circuit connection with the circuit board 2 through the pins 31. The fact that the pins 31 are flush with the bottom of the first plug terminal 3 ensures that the first plug terminal 3 can be stably installed on the circuit board 2 and that the first plug terminal 3 will not easily move on the circuit board 2. In this embodiment, there are four pins 31, which are arranged in parallel. The first plug terminal 3 can be stably installed on the circuit board 2 through the four pins 31.
[0039] See Figure 3 and Figure 4 The bottom of the first plug terminal 3 is formed with a protrusion 33, and the corresponding position on the circuit board 2 is formed with a plug hole 21 that matches the protrusion 33. The protrusion 33 is inserted into the plug hole 21. In this embodiment, there are two protrusions 33 and two plug holes 21. The two protrusions 33 are respectively inserted into the two plug holes 21. In this way, when assembling the first plug terminal 3 and the circuit board 2, the two protrusions 33 on the first plug terminal 3 are first inserted into the two plug holes 21 on the circuit board 2 to determine the relative position of the first plug terminal 3 and the circuit board 2. At this time, the four pins 31 on the first plug terminal 3 are respectively aligned with the four corresponding contacts on the circuit board 2 and will not move relative to each other. Then, the four pins 31 on the first plug terminal 3 can be directly soldered onto the circuit board 2, thereby improving the efficiency of assembling the first plug terminal 3 and the circuit board 2 and ensuring that the assembly of the first plug terminal 3 and the circuit board 2 is fast and accurate.
[0040] See Figure 3 and Figure 4 A socket 32 is formed on the first plug terminal 3. The socket 32 is located on the side of the first plug terminal 3, and the socket 32 and the free end of the pin 31 are respectively located on opposite sides of the first plug terminal 3. One end of the pin 31 is soldered to the circuit board 2, and the other end of the pin 31 passes through the first plug terminal 3 and is located in the socket 32. In this embodiment, there are four sockets 32, which are arranged in parallel. One end of the four pins 31 is soldered to the circuit board 2, and the other end of the four pins 31 passes through the first plug terminal 3 and is located in the four sockets 32.
[0041] The second connector 4 is plugged into the first connector 3. For details, please refer to [link / reference]. Figures 2 to 4The bottom of the second plug terminal 4 is equipped with a plug piece 42. The plug piece 42 can be inserted into the plug slot 32 and connected to the pin 31 in the plug slot 32. In this embodiment, there are four plug pieces 42. The four plug pieces 42 are arranged in parallel and are respectively inserted into the four plug slots 32. Each plug piece 42 is connected to the pin 31 in the corresponding plug slot 32. The second plug terminal 4 achieves circuit connection with the four pins 31 on the first plug terminal 3 through the four plug pieces 42, thereby realizing the circuit connection between the second plug terminal 4 and the DC socket 1 through the first plug terminal 3, the circuit board 2, and the DC socket 1.
[0042] In this embodiment, there are four pins 31, four slots 32, and four connectors 42. The first connector 3 can be securely mounted on the circuit board 2 through the four pins 31. The second connector 4 can be securely mounted on the first connector 3 through the insertion and engagement of the four connectors 42 with the four slots 32. Moreover, the DC socket 1 achieves circuit conduction with the second connector 4 through the four pins 31 and the four connectors 42, which can ensure a relatively large input current and guarantee the stability and reliability of the oxygen concentrator motherboard. In addition, when assembling the second connector 4 and the first connector 3, simply align the outermost connector 42 on the second connector 4 with the outermost slot 32 on the first connector 3, and then press firmly to insert the four connectors 42 on the second connector 4 into the four slots 32 on the first connector 3. The assembly of the second connector 4 and the first connector 3 is very simple.
[0043] See Figures 1 to 4 The second connector 4 is equipped with connector pins 41. After the connector pins 41 are inserted into the second connector 4, they are connected to the connector pieces 42 inserted into the second connector 4 to achieve circuit connection between the connector pins 41 and the connector pieces 42. In this embodiment, there are four connector pins 41, which are arranged in parallel. The four connector pins 41 are respectively connected to the four connector pieces 42. The four connector pins 41 can be respectively inserted into the four matching pin holes on the oxygen concentrator motherboard to achieve circuit connection between the connector pins 41 and the oxygen concentrator motherboard. The second connector 4 can be firmly inserted into the oxygen concentrator motherboard through the four connector pins 41. Moreover, the DC socket 1 connects to the oxygen concentrator motherboard through the four pins 31, the four connector pieces 42, and the four connector pins 41, which can ensure a relatively large input current and ensure the stability and reliability of the motherboard.
[0044] See Figure 3 and Figure 4 The connector pin 41 is located on the side of the second connector terminal 4, and the connector piece 42 is located at the bottom of the second connector terminal 4, which facilitates the spatial layout of the DC socket structure in the oxygen generator housing.
[0045] The connector pin 41 is interference-fitted with the connector hole on the oxygen concentrator mainboard. The diameter of the connector pin 41 is approximately the same as the diameter of the connector hole on the oxygen concentrator mainboard that mates with the connector pin 41. Alternatively, the diameter of the connector pin 41 can be slightly larger than the diameter of the connector hole on the oxygen concentrator mainboard. This ensures that the second connector terminal 4 can be securely installed on the oxygen concentrator mainboard and that the connector pin 41 on the second connector terminal 4 will not easily come loose from the oxygen concentrator mainboard, thus ensuring the stability of charging the oxygen concentrator.
[0046] See Figures 1 to 5 The DC socket structure of this utility model has four pins 41 on the second plug terminal 4, which are respectively plugged into four matching pin holes on the oxygen concentrator main board 5. The DC socket 1 connects to the oxygen concentrator main board 5 through the circuit board 2, the four pins 31 on the first plug terminal 3, the four plug tabs 42 on the second plug terminal 4, and the four pins 41. The connection between the DC socket 1 and the oxygen concentrator main board 5 through the four pins 31, four plug tabs 42, and four pins 41 can ensure a relatively large input current and guarantee the stability and reliability of the oxygen concentrator main board 5. When the DC socket 1 has a poor connection, it is only necessary to remove the pins 41 on the second plug terminal 4 from the pin holes on the oxygen concentrator main board 5, and then re-plug the pins 41 on the new DC socket structure into the pin holes on the oxygen concentrator main board 5 to complete the replacement of the DC socket structure. It is very quick and convenient without disassembling the entire main board of the oxygen concentrator.
[0047] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art in conjunction with existing common knowledge fall within the protection scope of this utility model.
