Description

Technical Field

[0001] This application relates to the field of massage equipment that can be used in water, and in particular to a waterproof electrical connection structure and a device using the waterproof electrical connection structure. Background Technology

[0002] Patent publication CN216168767U discloses a buttock massage therapy device. The advantages of this device lie in its ability to relieve fatigue, relax the mind and body, and treat physical pain through electrotherapy technology. The part in contact with the skin offers a very high level of comfort. Furthermore, its waterproof design allows for application in multiple scenarios, overcoming the previous limitation of not being able to massage in water, enabling the product to be used during bathing.

[0003] Based on this existing technology, our team has extended the technology of this massage therapy device by adding a leg-specific massage unit, which allows for simultaneous massage of the legs and buttocks in water. Considering the single usage scenario where only the buttocks need to be massaged, a detachable power connection is adopted between the leg-specific massage unit and the buttock massage therapy device.

[0004] When the electrical connection structure used to achieve this detachable electrical connection method is submerged in water, if the live parts of the electrical connection structure are exposed to water during long-term use, the exposed live parts will be ionized and corroded. In particular, if there is a loose connection at the connection point, the ionization corrosion will be more severe, which will lead to damage to the exposed live parts and even poor contact.

[0005] Therefore, there is an urgent need to develop a detachable electrical connection structure with good waterproof performance and reliable connection.

[0006] In the prior art, such as the electric rail and rail socket with quick connector disclosed in patent publication CN222785603U, there is a power supply component and a power receiving component. The power supply component includes at least one energized power supply connector; the power receiving component includes at least one power receiving connector and a power receiving rail body, with at least one power receiving connector connected to the power receiving rail body; the power supply component is configured to be detachably connected to the power receiving component, and the power supply connector is configured to be detachably connected to the power receiving connector. Although it achieves quick connection between the power supply component and the power receiving component, the disclosed technical solution does not have the ability to be waterproof or prevent loose connections. Utility Model Content

[0007] The purpose of this application is to propose a waterproof electrical connection structure and a device for using the waterproof electrical connection structure, which solves the problems that existing electrical connection structures cannot be waterproofed and cannot prevent loose connections.

[0008] To achieve the above objectives, this application adopts the following technical solution:

[0009] On one hand, this application provides a waterproof electrical connection structure, including: a female connector, the female connector having a slot and a first electrical terminal disposed in the slot; a male connector, the male connector having a plug and a second electrical terminal disposed on the plug, the plug being used to insert into the slot so that the first electrical terminal contacts the second electrical terminal; a waterproof structure for preventing water from entering the slot; and a connection confirmation switch for detecting the position of the plug inserted into the slot.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the first power terminal is a pin header; the second power terminal is a female header corresponding to the first power terminal; when the plug is inserted into the slot, the pin header is inserted into the female header.

[0011] Based on the above solution and as a preferred embodiment of the above solution: the waterproof structure includes a first elastic layer, which is disposed on the peripheral surface of the slot and / or the plug; and when the plug is inserted into the slot, the plug and the slot are interference-fitted.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the material of the first elastic layer is one of silicone, rubber or TPR.

[0013] Based on the above solution and as a preferred embodiment of the above solution: the waterproof structure includes an annular protrusion on the slot and / or plug, the protrusion being elastic.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the waterproof electrical connection structure further includes a waterproof cover, the waterproof cover is provided with a plug, and a second elastic layer is provided on the peripheral surface of the plug; the plug is used to insert into the slot, and when the plug is inserted into the slot, the plug and the slot are interference-fitted.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: the inner cross section of the slot is elongated, and a limiting protrusion extending along the depth direction of the slot is provided on one side of the slot; the shape of the plug is elongated and adapted to the shape of the slot, and a limiting groove adapted to the limiting protrusion is provided on one side of the plug.

[0016] Based on the above scheme and as a preferred embodiment of the above scheme: of the first power terminal and the second power terminal, one is a power supply terminal and the other is a power receiving terminal; of the female connector and the male connector, one of them with a power supply terminal is a power supply connector and the other is a power receiving connector; the connection confirmation switch includes a Hall switch and a magnet, the Hall switch is disposed on the power supply connector and the magnet is disposed on the power receiving connector, and when the plug is inserted into the slot, the magnet approaches the sensing part of the Hall switch.

[0017] Based on the above scheme and as a preferred embodiment of the above scheme: the connection confirmation switch also includes a controller, the Hall switch is connected to the controller (such as a microcontroller), and the controller is used to connect to and control the circuit of the power supply terminal.

[0018] On the other hand, based on the same technical concept of this application, this application also provides a device using a waterproof electrical connection structure, which includes the waterproof electrical connection structure described above.

[0019] To address the issues of existing electrical connection structures being unable to provide waterproofing and prevent loose connections, this application offers the following advantages:

[0020] The waterproof electrical connection structure of this application connects to the power source by the cooperation of a plug and a slot. Specifically, when the plug is inserted into the slot, the first electrical terminal contacts the second electrical terminal to achieve electrical connection.

[0021] The waterproof structure prevents water from entering the slot, thus avoiding ionization at the connection between the first and second electrical terminals. It also prevents the positive and negative electrodes of the first terminal from being energized in water when the first and second electrical terminals are not connected, which could cause ionization of the metal terminals and the formation of scale and other deposits.

[0022] The connection confirmation switch is used to determine whether the plug is effectively inserted into the slot, thus avoiding unreliable contact between the first and second electrical terminals, which could result in a loose connection.

[0023] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0043] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

When a component is referred to as "connected to" another component, it can be directly or indirectly connected to that other component.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality of" means two or more, unless otherwise explicitly defined.

[0045] While existing electrical connection structures enable rapid connection between power supply and receiving components, they lack waterproofing and the ability to prevent loose connections. If used while submerged in water, exposed live parts will be subject to ionization corrosion. This corrosion is particularly severe when loose connections occur, leading to damage to the exposed live parts and even poor contact.

[0046] See Figure 1-9 This application discloses a waterproof electrical connection structure and a device for using the waterproof electrical connection structure, which can be used when immersed in water, and solves the problems that existing electrical connection structures cannot be waterproofed and cannot prevent loose connections.

[0047] On the one hand, such as Figure 1 As shown, this application discloses a waterproof electrical connection structure, which includes a female connector 100, a male connector 200, a waterproof structure 300, and a connection confirmation switch 400. The female connector 100 has a slot 101 and a first electrical terminal 102 disposed in the slot 101; the male connector 200 has a plug 201 and a second electrical terminal 203 disposed on the plug 201; the plug 201 is inserted into the slot 101, and when the plug 201 is inserted into the slot 101, the first electrical terminal 102 contacts the second electrical terminal 203; the waterproof structure 300 prevents water from entering the slot 101; and the connection confirmation switch 400 detects and determines whether the plug 201 is inserted into the slot 101, determines the position of the plug 201 inserted into the slot 101, and ensures effective contact between the first electrical terminal 102 and the second electrical terminal 203.

[0048] This waterproof electrical connection structure connects the plug 201 to the slot 101. Specifically, when the plug 201 is inserted into the slot 101, the first electrical terminal 102 contacts the second electrical terminal 203, establishing electrical conductivity. The waterproof structure 300 prevents water from entering the slot 101, avoiding ionization at the connection point of the first and second electrical terminals 102. This prevents ionization corrosion and also prevents scale and other deposits from forming when the first and second electrical terminals 102 are not connected, as this could lead to ionization of the metal terminals. A connection confirmation switch 400 checks whether the plug 201 is properly inserted into the slot 101, preventing unreliable contact between the first and second electrical terminals 102 and 203, which could result in a loose connection.

[0049] In the embodiments of this disclosure, such as Figure 2-4 As shown, the first power terminal 102 is a pin header. Under normal circumstances, one end of the pin header is exposed in the slot 101, and the other end extends into the female connector 100 and connects to the corresponding power supply module or energized functional module. The second power terminal 203 is a female connector corresponding to the first power terminal 102. The female connector extends from the end face of the plug 201 (the side that abuts against the bottom of the slot 101) along the depth direction of the plug 201 (the protruding direction corresponding to the depth of the slot 101). The pins of the female connector are connected to another energized module corresponding to the power supply module or energized functional module. When the plug 201 is inserted into the slot 101, the pin header is inserted into the female connector to complete the power connection.

[0050] Furthermore, such as Figure 2 As shown, the inner cross-section of the slot 101 is elongated, and a limiting protrusion 103 extending along the depth direction of the slot 101 is provided on one side of the slot 101, as shown in the figure. Figure 3 As shown, the pin headers are arranged along the length of slot 101; Figure 4 As shown, the plug 201 is elongated and fitted to the shape of the slot 101. One side of the plug 201 has a limiting groove 202 that matches the limiting protrusion 103. The busbar is provided on the plug 201 and corresponds to the busbar. By providing the limiting protrusion 103 on the slot 101 and the limiting groove 202 on the plug 201, a foolproof design is formed between the slot 101 and the plug 201. The plug 201 can only be inserted into the slot 101 when the limiting protrusion 103 matches the limiting groove 202 (the limiting protrusion 103 is embedded in the limiting groove 202). This avoids the plug 201 being inserted into the slot 101 in an incorrect posture, which could lead to incorrect wiring sequence between the first power terminal 102 and the second power terminal 203.

[0051] In some implementations, the waterproof structure 300 may be the application of a sealing ring between the female connector 100 and the male connector 200. However, the sealing ring is not securely fixed and may fall off, and it appears visually obtrusive, making it unsuitable for use in technological products with a high-quality, exposed appearance.

[0052] In this embodiment, the waterproof structure 300 includes a first elastic layer 301, which is disposed on the peripheral surface of the slot 101 or the plug 201. Preferably, the first elastic layer 301 is disposed simultaneously on the peripheral surfaces of both the slot 101 and the plug 201, i.e., simultaneously on the inner annular sidewall of the slot 101 and the outer annular sidewall of the plug 201. When the plug 201 is inserted into the slot 101, the plug 201 and the slot 101 are in an interference fit. Through the tight contact of the two contacting surfaces when the plug 201 is inserted into the slot 101, a waterproof sealing connection is achieved.

[0053] In some embodiments, the waterproof structure 300 may further include an annular protrusion 302 disposed on the slot 101 or the plug 201. The protrusion 302 is elastic. Generally, the annular protrusion 302 can be disposed on the plug 201. Firstly, the elastic protrusion 302 can form a seal between the plug 201 and the slot 101. Secondly, when the surface of the protrusion 302 also has a first elastic layer 301, the protrusion 302 and the first elastic layer 301 can form a mutually interlocking fit. While enhancing the sealing performance, it also plays a sealing role in preventing the plug 201 from sliding relative to the slot 101.

[0054] In some embodiments, the waterproof structure 300 further includes annular protrusions 302 on the slot 101 and the plug 201, the protrusions 302 being elastic. That is, corresponding protrusions 302 are provided on both the slot 101 and the plug 201. When the plug 201 is inserted into the slot 101, the protrusions 302 on the slot 101 and the protrusions 302 on the plug 201 can achieve an alternating engagement effect, resulting in better sealing and better anti-dislodgement effect. However, such a structure provides greater resistance when inserting and removing the plug 201. Therefore, it is more preferable to provide annular protrusions 302 only on either the slot 101 or the plug 201.

[0055] The first elastic layer 301 and the protrusion 302 are both recommended to be made of non-conductive materials. Generally, the materials that can be selected are silicone, rubber or TPR, with non-conductive silicone being preferred.

[0056] The silicone material has good adhesion and good adhesion after contact, which can not only ensure the sealing performance, but also increase the friction between them to prevent unnecessary separation between the slot 101 and the plug 201.

[0057] In the embodiments of this disclosure, such as Figure 5-6 As shown, the waterproof electrical connection structure also includes a waterproof cover 500, which is provided with a plug 501. A second elastic layer 502 is provided on the peripheral surface of the plug 501. The plug 501 is used to insert into the slot 101. When the plug 501 is inserted into the slot 101, the plug 501 and the slot 101 are in an interference fit. After the male connector 200 is removed from the female connector 100, the plug 501 can be inserted into the slot 101 to protect the first electrical terminal 102 from external contamination, and to prevent the first electrical terminal 102 from being exposed for a long time, which would cause external oil mist or other substances to adhere to the surface of the first electrical terminal 102 and cause contamination.

[0058] In this embodiment, of the first power terminal 102 and the second power terminal 203, one is a power supply terminal and the other is a power receiving terminal; of the female connector 100 and the male connector 200, one with a power supply terminal is a power supply connector and the other is a power receiving connector; generally, the female connector 100 is a power supply connector, used to set the pin header as the first power terminal 102 (i.e., the power supply terminal), and the male connector 200 is a power receiving connector, used to set the female connector as the second power terminal 203 (i.e., the power receiving terminal). Wherein, as... Figure 2 and Figure 3 As shown, the connection confirmation switch 400 includes a Hall effect switch 402 and a magnet 403. The Hall effect switch 402 is disposed on the power supply connector, and the magnet 403 is disposed on the power receiving connector. When the plug 201 is inserted into the slot 101, the magnet 403 approaches the sensing part of the Hall effect switch 402 (generally the end away from the power receiving pin). That is, the Hall effect switch 402 is disposed on the female connector 100, as... Figure 3 As shown, the Hall effect switch 402 is preferably located near the bottom surface of the slot 101 on the female connector 100, and the Hall effect switch 402 is connected to the corresponding circuit; the magnet 403 is located on the male connector 200, as shown. Figure 4 As shown, it is preferably disposed at the end of the plug 201; when the plug 201 is inserted into the slot 101, the magnet 403 approaches the Hall switch 402, and the Hall switch 402 generates an electrical signal by being affected by the magnet 403 to determine whether the plug 201 and the slot 101 are properly matched, thereby preventing the first power terminal 102 and the second power terminal 203 from being poorly connected due to improper matching of the plug 201 and the slot 101.

[0059] Furthermore, such as Figure 8 and 9 As shown, the connection confirmation switch 400 also includes a controller 401, and the Hall effect switch 402 is connected to the controller 401, as shown in the connection method. Figure 7 and Figure 8As shown, the controller 401 is used to connect to and control the circuit of the power supply terminal. It determines the connection relationship between the plug 201 and the slot 101 through the Hall effect switch 402, and then controls whether the circuit connecting the power supply terminal needs to supply power to the output terminal (the end where the powered accessory is located) where the first power terminal 102 and the second power terminal 203 are located. That is, when the powered accessory is not connected (when the first power terminal 102 and the second power terminal 203 are not connected), the controller 401 controls the circuit connecting the power supply terminal not to output any voltage to other connection terminals (such as the first power terminal) in the female connector except for the Hall effect switch.

[0060] It is worth noting that this waterproof electrical connection structure can be used for both signal transmission line connections and general electrical circuit connections.

[0061] On the other hand, this application discloses a device using a waterproof electrical connection structure, including the waterproof electrical connection structure described above.

[0062] In some implementations, such as Figure 5 and Figure 6 As shown, the device employing the waterproof electrical connection structure is a buttock massage therapy device. A detachable leg massage unit 700 is externally connected to the main body 600 of the buttock massage therapy device. The main body 600 and the leg massage unit 700 are connected via the aforementioned waterproof electrical connection structure. The female connector 100 is located on the main body 600 of the buttock massage therapy device. The electronic control unit 800 and the controller 401 are both located inside the main body 600. The electronic control unit 800 includes an output circuit connected to the controller 401. The output circuit is as follows... Figure 9 As shown, according to Figure 7 The controller 401 is shown. The output circuit connection terminals (S2-, S2+) are connected to the first power terminal 102. Then, the leg massage unit 700 is connected to the second power terminal 203. The connection between the buttock massage therapy device body 600 and the leg massage unit 700 is realized through the cooperation of the first power terminal 102 and the second power terminal 203.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
