Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electronic device that communicates with accessory devices via an electrical connector kit. Background Technology

[0002] Electronic devices can achieve coupling between multiple associated accessory devices through electrical connector kits, with the receptacle connectors of the electronic devices mating with the plug connectors of the mating electrical connector kits.

[0003] Some electronic devices often require two electrical signal channels to achieve different functional uses. For example, in the medical field, a medical electronic device may simultaneously connect to a detection channel and an electrical stimulation release channel, acting on different parts of the human body at the same time. However, due to design and manufacturing cost considerations, electronic device manufacturers often use the same undesigned socket shape for the various connectors in the electronic devices. When the operator inserts the plug and connector of the electrical connector kit, there is a certain probability of incorrect insertion. Frequent incorrect insertions also carry the risk of unpredictable damage to the corresponding socket and connector, resulting in a poor user experience. Utility Model Content

[0004] This utility model provides an electronic device that communicates with accessory devices via an electrical connector kit. The various socket connectors of the electronic device have different foolproof designs, which reduces the phenomenon of mis-insertion when plugging and unplugging the plug connectors of the electrical connector kit, and avoids the risk of unpredictable damage to both the plug connectors and socket connectors due to incorrect connection.

[0005] This utility model embodiment provides an electronic device that communicates with an accessory device via an electrical connector kit. The electrical connector kit has at least two electrical connectors. One end of each electrical connector has a plug connector that can be plugged into and electrically connected to a socket connector of the electronic device, and the other end is electrically connected to the accessory device. Each plug connector includes a housing with a foolproof portion extending along the outer surface of its outer wall. The electronic device includes a device housing with a foolproof opening extending inward along the outer surface of its surface wall and in a first direction.

[0006] The socket connector is arranged inside the anti-fooling opening and located on the extension line of the first direction. The anti-fooling part can be inserted into the anti-fooling opening along the first direction to realize the plug connector and the socket connector plug-in electrical connection.

[0007] The number of the anti-fooling ports is adapted to the number of the plug connectors, and the configuration of any of the anti-fooling ports is different.

[0008] Optionally, the foolproof opening has a foolproof inner surface that is 180 degrees symmetrical along the first direction, so that the socket connector can accept the insertion of the foolproof part in either of the two directions of the plugging connection.

[0009] Optionally, the socket connector includes a tongue having a first surface and a second surface, a plurality of first electrical contacts being disposed on the first surface of the tongue, and a plurality of second electrical contacts being disposed on the second surface of the tongue;

[0010] The first and second surfaces of the tongue are 180 degrees symmetrical along the first direction, so that the plug connector can achieve electrical connection after being inserted into the socket connector in either of the two directions of the electrical connection.

[0011] Optionally, the plurality of the foolproof openings are all located on the same side surface wall of the device housing.

[0012] Optionally, the configurations of two adjacent anti-foolproof openings have significant visual differences.

[0013] Optionally, at least one foolproof mark is provided on the surface wall of the device housing near each of the foolproof ports, and each foolproof mark corresponds to the plug connector adapted to the foolproof port it is located on.

[0014] Optionally, the number of the foolproof notches is the same as the number of the plug connectors.

[0015] Optionally, the electronic device is either a pelvic floor device main unit or an optical beauty device main unit.

[0016] This invention provides an electronic device that communicates with accessory devices via an electrical connector kit. The keying features of each connector socket in this electronic device are different, ensuring that users do not accidentally plug the connectors into the device, and further reducing the risk of damage to the connector sockets within the electronic device.

Figure 2 This is a schematic diagram of another electrical connector with a Type-C plug and an accessory device electrically connected thereto, which is a vaginal electrode, provided by an embodiment of this utility model. Figure 3This is a schematic diagram of the structure of an electronic device that communicates with accessory devices via an electrical connector kit, according to an embodiment of this utility model. Figure 4 This is a schematic diagram of the structure of assembling a socket connector on a PCB circuit board inside an electronic device, provided by an embodiment of this utility model.

[0037] As shown in the diagram, the electrical connector 10 includes a plug connector 11 in a socket connector 33 that can be plugged into and electrically connected to an electronic device 30. Furthermore, the electrical connector 10 connects the plug connector 11 to an accessory device 20 via a first wire 15. Each accessory device 20 has a different structure to provide diverse functions to the user. For example… Figure 1 The accessory device 20 includes two flexible electrode pads, namely a first flexible electrode pad 21 and a second flexible electrode pad 22. Both are electrically connected to a splitter 23 via a second wire 211 and a third wire 221, respectively. The other end of the splitter 23 is electrically connected to a plug connector 11 via a first wire 15. In use, the two flexible electrode pads can be attached to the user's abdomen to monitor the electrical signals in the abdomen. Figure 2 The accessory device 20 includes a vaginal electrode, which has a first metal electrode piece 241 and a second metal electrode piece 242 respectively disposed on the electrode body 24. Its end is electrically connected to a connector 23 via a fourth wire 25. The other end of the connector 23 is electrically connected to a plug connector 11 via a first wire 15. This device is used to perform pelvic floor rehabilitation and treatment on the user. Specifically, each plug connector 11 includes a housing 111, which has a foolproof part 112 extending along its outer surface. The foolproof part 112 can be provided differently according to design requirements, for example... Figure 1 The foolproof part 112 is designed to have four openings 13 formed circumferentially along the end of the housing 111, while Figure 2 The foolproof part 112 is designed to form two openings 13 symmetrically along the vertical direction of the housing 111. Its ultimate purpose is to adapt to the shape of the foolproof opening 35 in the electronic device 30. Therefore, it can be adjusted to various shapes according to actual needs. At the same time, a wing 12 for plugging into the socket connector 33 is provided at the front end of the housing 111. The extension direction along the length of the wing 12 is the plugging and electrical connection direction 02 of the electrical connector 10 in the use state. At the end of the housing 111 near the wing 12, there is a stop surface 14. When the electrical connector 10 is plugged into the foolproof opening 35 along the plugging and electrical connection direction 02, the stop surface 14 abuts against the bottom wall of the foolproof opening 35 to indicate to the user that the correct electrical connection position has been reached.

[0038] The electronic device 30 shown in the figure includes a device housing with a foolproof notch 35 extending inward along the outer surface of its surface wall 31 and along a first direction 01. A socket connector 33 is arranged inside the foolproof notch 35 and located on the extension line of the first direction 01. It should be noted that the plug-in electrical connection direction 02 extends along the length of the wing 12. When it is electrically connected to the electronic device 30, the first direction 01 and the plug-in electrical connection direction 02 are in the same direction, meaning the foolproof part 112 can be inserted into the foolproof notch 35 along the first direction 01 to achieve electrical connection between the plug connector 11 and the socket connector 33. The number of foolproof notches 35 is matched with the number of plug connectors 11, and the configuration of any foolproof notch 35 is different.

[0039] First, the electrical connector kit in this embodiment can provide a communication path between the electronic device 30 and the corresponding accessory device 20. For example, one end of any electrical connector 10 in the electrical connector kit is electrically connected to the electronic device 30, and the other end of the electrical connector 10 is electrically connected to the corresponding accessory device 20, so that the electronic device 30 can be configured to control the operation or running of the corresponding accessory device 20, and the accessory device 20 can also transmit its own data to the corresponding electronic device 30 for analysis or storage.

[0040] Secondly, the socket connector 33 is disposed inside the electronic device 30 and is assembled with a PCB circuit board 37 to achieve electrical connection. The PCB circuit board 37 provides support for the socket connector 33 and transmission of circuit signals. After being assembled inside the electronic device 30, it can ensure that the insertion end of the socket connector 33 is located inside the keying opening 35. At the same time, in order to ensure electrical connection after insertion, the socket connector 33 is located on the extension line of the first direction 01. In this way, the keying part 112 of the electrical connector 10 can be smoothly inserted into the keying opening 35 along the first direction 01 to realize the plug connector 11 and the socket connector 33 plugging and connecting.

[0041] For example, Figure 1-4 In this context, electronic device 30 has two socket connectors 33, and the corresponding electrical connector kit also includes two plug connectors 11. The two socket connectors 33 correspond to different application scenarios or different types of accessory devices 20; Figure 1 In this context, the accessory device 20 can be an abdominal monitoring electrode with two flexible electrode pads (i.e., the accessory device 20 includes two flexible electrode pads, one positive and one negative, a first flexible electrode pad 21 and a second flexible electrode pad 22). Figure 2 In this context, the accessory device 20 can be a vaginal electrode with two metal electrode pads (i.e., the accessory device 20 includes an electrode body 24 and two metal electrode pads 241 and 242, one positive and one negative, mounted on the electrode body 24). More specifically, Figure 1and Figure 2 The plug connector 11 has a completely different design of the foolproof part 112 to ensure synchronous adaptation with the electronic device 30. If the two socket connectors 33 have the same structure for the foolproof opening 35, the electrical connector 10 of the abdominal monitoring electrode will be inserted into the foolproof opening 35 that should be inserted by the electrical connector 10 of the vaginal electrode. This undoubtedly increases the user's identification cost and the cost of correctly and quickly inserting the electronic device 30. Furthermore, different socket connectors 33 may have different designs for corresponding pins or electrical contacts due to communication requirements within the channel. Once the above-mentioned mis-insertion occurs, there may be unexpected damage to the socket connector 33 or / and the plug connector 11, such as pin bending. Therefore, for electronic devices 30 with at least two socket connectors 33, the different configurations of any foolproof opening 35 can effectively avoid the unexpected risks caused by mis-insertion of the accessory device 20, which not only further improves the user experience but also reduces the risk of device damage.

[0042] In addition, the electronic device 30 includes a socket connector 33 for electrical connection with the accessory device 20, as well as a power supply port 32, so that the electronic device 30 can operate by external power supply.

[0043] It is important to understand that in this case, any foolproof port 35 has a different configuration, which means that the electrical connector 10 that is plugged into it needs to have a compatible foolproof part 112 shape. Based on the matching of the structure of the foolproof part 121 and the structure of the foolproof port 21, Figure 1 The electrical connector 10 can be smoothly inserted into Figure 3 The connector 33 on the left side of the socket cannot be inserted into the connector 33 on the right side; similarly, Figure 2 The same applies to electrical connector 10 in the middle.

[0044] See Figure 5-8 , Figure 5 This is a frontal projection view of the foolproof notch and socket connector of an electrical connector with an adapter for Lightning plugs provided in this embodiment of the present invention. Figure 6 The present invention provides an embodiment with an adaptability. Figure 1 The image shows a keyed-in notch and a receptacle view of an electrical connector with a Type-C plug. Figure 7 This is a frontal projection view of a foolproof port and a socket connector of another electrical connector adapted to a Lightning plug, provided in an embodiment of this utility model. Figure 8 The present invention provides an embodiment with an adaptability. Figure 2 The image shows a keyed-in notch for another electrical connector with a Type-C plug, and a projected view of the socket connector. Figure 5As can be seen in the example, the four corners of the anti-foolproof opening 35 have protruding convex parts 351, corresponding to which in Figure 1 The electrical connector 10 has four matching openings 13. During insertion, the protrusions 351 and the shapes of the openings 13 limit the relative positional relationship between the plug connector 11 and the socket connector 33, achieving a foolproof effect. Correspondingly, in Figure 7 As can be seen in the example, the anti-foolproof opening 35 has two symmetrically arranged protrusions 351 on its upper and lower sides, corresponding to which in Figure 2 The electrical connector 10 is provided with two matching openings 13. When plugged in, the shape of the protrusion 351 and the opening 13 can limit the relative positional relationship between the plug connector 11 and the socket connector 33, and achieve a foolproof effect. It can be understood that the structure based on the foolproof opening 35 and the foolproof part 112 can also be other shape-matching structures, which will not be described in detail here.

[0045] Furthermore, it should be noted that for electronic devices and electrical connectors in the medical field, the plug of the electrical connector has multiple upright pins, and the socket connector of the electronic device has corresponding circular holes for each pin as a mating interface. Long-term use has revealed that this plug and socket design, due to the thin and relatively long pins of the plug, can cause the ends of the pins to partially abut against the surface of the socket when incorrectly inserted. Frequent insertion and removal can easily lead to pin bending, resulting in the pins failing to properly align with the correct socket. Repeated insertion and removal can cause pin bending and misalignment (blind insertion).

[0046] Optionally, continue to refer to Figure 3 and Figure 5-8 The foolproof opening 21 has a 180-degree symmetrical foolproof inner surface along the first direction 01, so that the socket connector 33 can accept the insertion of the foolproof part 112 in either of the two plugging electrical connection directions.

[0047] Specifically, the extension direction along the length of the wing 12 is the insertion electrical connection direction 02 of the electrical connector 10 in the use state. The foolproof part 112 is constructed with a foolproof outer surface with 180-degree symmetry, and the foolproof opening 35 has a foolproof inner surface with 180-degree symmetry. The foolproof opening 35 is generally flat, which allows the user to have two easily observable design surfaces for insertion when the plug connector 11 and the socket connector 33 are mated. This also simplifies the design and manufacturing difficulty of the foolproof part 121 and the foolproof opening 35.

[0048] See also Figure 5-8In some embodiments, the keying notch 35 may be designed such that it is divided into upper and lower halves along a horizontal plane bisecting its center, so that the physical shape of the cross-section of the upper half of the keying notch 35 is substantially the same as that of the lower half. Similarly, if it is divided into left and right halves along a vertical plane bisecting its center, the physical shape of the cross-section of the left half of the keying notch 35 is substantially the same as that of the right half. In other bidirectional embodiments, the cross-sectional shape of the keying notch 35 need not be perfectly symmetrical, as long as the electrical connector 10 does not include a key that prevents the plug connector 11 from being inserted into the corresponding socket connector 33 in two different directions and the electrical contacts of the plug connector 11 are correctly aligned with the electrical contacts in the corresponding socket connector 33 in either direction.

[0049] Optionally, see [link to relevant documentation] Figure 5-8 The socket connector 33 includes a tongue 34, which has a first surface 341 and a second surface 343. A plurality of first electrical contacts 342 are provided on the first surface 341 of the tongue 34, and a plurality of second electrical contacts 344 are provided on the second surface 343 of the tongue 34. The first surface 341 and the second surface 343 of the tongue 34 are 180 degrees symmetrical along the first direction O1, so that the plug connector 11 can achieve electrical connection after being inserted into the socket connector 33 in either of the two directions of electrical connection.

[0050] Specifically, the tongue 34 is sized to accommodate the flaps 12 of the corresponding electrical connector 10 during a mating event. The tongue 34 has a first surface 341 and a second surface 343 arranged parallel and opposite to each other. A plurality of first electrical contacts 342 are provided on the first surface 341 of the tongue 34, and a plurality of second electrical contacts 344 are provided on the second surface 343 of the tongue 34. Exemplarily, the number of first electrical contacts 342 is the same as the number of second electrical contacts 344, and the orthographic projections of the first electrical contacts 342 on the first surface 341 correspond one-to-one with the orthographic projections of the second electrical contacts 344 on the first surface 341, with the projections overlapping. Exemplarily, these electrical contacts can be classified as data contacts. Exemplarily, the shapes of the first electrical contacts 342 and the second electrical contacts 344 can be square, circular, leaf spring, or cantilever beam, etc. This embodiment is merely an example and is not limited thereto. For example, in one specific embodiment, each first electrical contact 342 is located on the same side of the first surface 341, and each first electrical contact 342 is located on the side of the first surface 341 close to the second surface 343. Each second electrical contact 344 is located on the same side of the second surface 343, and each second electrical contact 344 is located on the side of the second surface 343 close to the first surface 341.

[0051] These electrical contacts can be raised, recessed, or flush with the inner surface of the tongue 34. These contacts can be electrically coupled to corresponding contacts in the plug connector 11 to facilitate a communication electrical connection between the electrical connector 10 and the electronic device 30. Exemplarily, these contacts can be made of copper, nickel, brass, stainless steel, metal alloys, or any other suitable conductive material or combination of conductive materials. Exemplarily, a first electrical contact 342 can be printed on a first surface 341 of the tongue 34, and a second electrical contact 344 can be printed on a second surface 343 of the tongue 34, using techniques similar to those used for printing contacts on a printed circuit board.

[0052] The tongue 34 can be designed with 180-degree symmetry and bidirectional use, which allows the plug connector 11 to be inserted into the socket connector 33 in either of the two directions of electrical connection to achieve electrical connection. In other words, the plug connector 11 corresponding to the socket connector 33 to which the tongue 34 belongs can be inserted into the socket connector 33 in one of the directions of electrical connection, and the plug connector 11 corresponding to the socket connector 33 to which the tongue 34 belongs can still be inserted into the socket connector 33 after rotating 180 degrees.

[0053] In some embodiments, the tongue 34 can be shaped such that if the tongue 34 is divided into upper and lower halves along a horizontal plane bisecting its center, the physical shape of the cross-section of the upper half of the tongue 34 is substantially the same as the physical shape of the cross-section of the lower half. Similarly, if the tongue 34 is divided into left and right halves along a vertical plane bisecting its center, the physical shape of the cross-section of the left half of the tongue 34 is substantially the same as the physical shape of the cross-section of the right half. In other bidirectional embodiments, the cross-sectional shape of the tongue 34 need not be perfectly symmetrical, as long as the electronic device 30 does not include keys that obstruct the receptacle connector 33 from receiving the corresponding plug connector 11 in two different directions and the electrical contacts of the receptacle connector 33 are correctly aligned with the electrical contacts in the corresponding plug connector 11 in either direction.

[0054] Furthermore, it should be noted that in this embodiment, the first surface 341 and the second surface 343 of the tongue 34 are limited to having 180-degree symmetry along the direction of the electrical connection. This is not a design based on existing pins or holes. The plug connector 11 can be an existing Type-C plug or Lightning plug. This embodiment is merely an example and is not intended to limit the design. Of course, the structure of the tongue 34 can also be adapted and manufactured by those skilled in the art. When applied to a Type-C plug or a Lightning plug, the electrical connector 10 can achieve bidirectional insertion and mating. That is, the electrical connector 10 can be paired and electrically connected with the socket connector 33 of the corresponding electronic device 30 in both orientations. One orientation can be understood as the other orientation rotated 180 degrees along the axis of symmetry. In this way, the solution of using a unified plug interface and electrical connection line in the product line can significantly reduce design and production costs. Furthermore, the socket connector 33 adapts its structure to existing Type-C or Lightning plugs, and with the matching configuration of the foolproof opening 35 and the foolproof part 112, the user can insert the electrical connector 10 into the electronic device 30 in either direction and ensure correct connection.

[0055] For example, see Figure 5 and Figure 7 , Figure 5 and Figure 7 All use a socket connector 33 that is compatible with Lightning plugs. In this embodiment, the tongue 34 is constructed as a flat ring shape, the first surface 341 and the second surface 343 are arranged on the inner side opposite to each other, and a first electrical contact 342 is arranged on the first surface 341 and a second electrical contact 344 is arranged on the second surface 343. Figure 5 In the middle, the anti-foolproof opening 35 has protruding convex parts 351 at the four corners, corresponding to the anti-foolproof opening 35. Figure 1 The electrical connector 10 is provided with four openings 13 that are adapted to it. When plugged in, the shape of the protrusion 351 and the opening 13 can limit the relative positional relationship between the plug connector 11 and the socket connector 33 and achieve a foolproof effect. Figure 7 In the middle, the anti-foolproof opening 35 has two symmetrically arranged protrusions 351 on the upper and lower sides, and corresponding to them in Figure 2 The electrical connector 10 is provided with two openings 13 that are adapted to it. When plugged in, the shape of the protrusion 351 and the opening 13 can limit the relative positional relationship between the plug connector 11 and the socket connector 33, and achieve the effect of preventing mistaken connection.

[0056] For example, see Figure 6 and Figure 8 , Figure 6 and Figure 8All use a socket connector 33 that is compatible with Type-C plugs. In this embodiment, the tongue 34 is constructed as a flat sheet configuration, the first surface 341 and the second surface 343 are arranged on the outer side relative to each other, and a first electrical contact 342 is arranged on the first surface 341 and a second electrical contact 344 is arranged on the second surface 343. Figure 6 In the middle, the anti-foolproof opening 35 has protruding convex parts 351 at the four corners, corresponding to the anti-foolproof opening 35. Figure 1 The electrical connector 10 is provided with four openings 13 that are adapted to it. When plugged in, the shape of the protrusion 351 and the opening 13 can limit the relative positional relationship between the plug connector 11 and the socket connector 33 and achieve a foolproof effect. Figure 8 In the middle, the anti-foolproof opening 35 has two symmetrically arranged protrusions 351 on the upper and lower sides, and corresponding to them in Figure 2 The electrical connector 10 is provided with two openings 13 that are adapted to it. When plugged in, the shape of the protrusion 351 and the opening 13 can limit the relative positional relationship between the plug connector 11 and the socket connector 33, and achieve the effect of preventing mistaken connection.

[0057] Optionally, refer to Figure 3 and Figure 4 Multiple keying notches 35 are all located on the same side surface wall 31 of the device housing. This facilitates the spatial layout of the socket connector 33 within the electronic device 30.

[0058] In addition, optionally, refer to Figure 3 At least one foolproof mark 36 is provided on the surface wall 31 of the device housing near each foolproof port 35. Each foolproof mark 36 corresponds to the plug connector 11 adapted to the foolproof port 35 it is located on. The foolproof mark can be a pattern, text, number, letter or a combination thereof, to further reduce the possibility of users inserting the wrong match.

[0059] In some embodiments, continue to refer to Figure 3 The shapes and configurations of two adjacent anti-foolproof openings 35 are quite different, which brings a significant visual difference to the user and further facilitates the user's identification and operation.

[0060] Optionally, continue to refer to Figure 3 The number of keying ports 35 is the same as the number of plug connectors 11. In this way, it can be ensured that each keying port 35 in the electronic device 30 can be plugged into the corresponding plug connector 11, avoiding the useless idleness of the keying ports 35 or the mismatch between the keying ports 35 and multiple plug connectors 11.

[0061] Optionally, the electronic device 30 can be either a pelvic floor device main unit or an optical beauty device main unit.
