Description

Technical Field

[0001] This application belongs to the field of conductive connection waterproofing technology, and particularly relates to a waterproof structure and electronic equipment. Background Technology

[0002] A connector female is an interface used to house connectors and enable power or signal transmission, including USB female connectors and Type-C female connectors. Generally, connector female connectors need to be waterproof to ensure better reliability and lifespan.

[0003] In related technologies, connector female sockets achieve waterproofing through internal potting. On the one hand, potting waterproofing has high production and maintenance costs; on the other hand, the adhesive can easily contaminate the contacts of the connector female socket, thereby impairing signal transmission performance or charging efficiency. Utility Model Content

[0004] This application provides a waterproof structure and electronic device that can form a sealed waterproof effect through elastic waterproof components, reducing contact contamination and cost increases caused by applying potting waterproofing, and is suitable for waterproofing various connector females.

[0005] In a first aspect, embodiments of this application provide a waterproof structure applied to a connector female socket. The waterproof structure includes a housing, an isolator, and an end cap. The housing is used to accommodate the connector female socket and includes an outer connecting portion, a stepped portion, and an inner connecting portion arranged sequentially along its own axial direction. The isolator is sleeved on the outer connecting portion, and a first waterproof component is sandwiched between the isolator and the stepped portion. The first waterproof component is capable of elastic deformation. The end cap is sleeved on the outer connecting portion and is used to cover the housing. The end cap and the housing are separated by the isolator. The end cap is threadedly connected to the outer connecting portion. Rotating the end cap causes the isolator to move closer to the stepped portion, so that the first waterproof component abuts against the isolator and the stepped portion.

[0006] In some embodiments, a second waterproof member is sandwiched between the end cap and the spacer. The second waterproof member is capable of elastic deformation. Rotating the end cap brings it closer to the spacer so that the second waterproof member abuts against the spacer.

[0007] In some embodiments, the second waterproof component includes a sealing portion and an anti-loss portion connected together, the sealing portion being sandwiched between the end cap and the isolator, and the anti-loss portion being connected to the end cap.

[0008] In some embodiments, the end cap includes a fixing nut and a cap body, a sealing portion is sandwiched between the fixing nut and the spacer, an anti-loss portion is connected to the cap body, the cap body is detachably connected to the fixing nut, or the cap body is detachably connected to the external connecting portion.

[0009] In some embodiments, the cover body is detachably connected to the outer connecting portion, and the end cap further includes a sealing gasket located inside the cover body. When the cover body is connected to the outer connecting portion, the sealing gasket abuts against the cover body and the outer connecting portion.

[0010] In some embodiments, a protrusion is provided inside the cover body, and a guide groove is provided on the outer connecting part. An inlet is opened on the side of the guide groove near the cover body. The protrusion enters the guide groove through the inlet and moves along the guide groove to achieve the cover body closing to the fixing nut.

[0011] In some embodiments, the waterproof structure further includes a limiting cover, which is detachably connected to the inner connection portion, and the limiting cover has a connection window to expose the connector female.

[0012] In some embodiments, the limiting cover is provided with a first guide structure, and the inner connecting part is provided with a second guide structure. The first guide structure and the second guide structure cooperate to assist the limiting cover in docking with the inner connecting part.

[0013] In some embodiments, the isolation member has a through hole for the external connection portion to pass through. The through hole is formed by at least a first side and a second side, wherein the first side is an arc side and the second side is a straight side.

[0014] Secondly, embodiments of this application provide an electronic device, which includes a connector female and a waterproof structure as described in any embodiment of the first aspect, wherein the connector female is mounted on a housing.

[0015] The waterproof structure of this application embodiment is applicable to connector female sockets. The waterproof structure has an end cap fitted onto the outer connecting portion of the housing. The end cap forms a seal around the housing to prevent moisture from directly entering. The waterproof structure also includes a spacer and a first waterproof component between the housing and the end cap. When the end cap is closed onto the housing, it presses the spacer towards the stepped portion of the housing. The first waterproof component undergoes elastic deformation to prevent moisture from seeping in through the connection between the end cap and the housing, further enhancing waterproof performance. This achieves waterproofing inside the housing without the need for potting compound, thus protecting the connector female socket. The end cap and the outer connecting portion are connected by threads, which helps maintain a tight seal between the first waterproof component and the spacer, and between the first waterproof component and the stepped portion.

[0037] A connector female is an interface used to house connectors and enable power or signal transmission, including USB female connectors and Type-C female connectors. Generally, connector female connectors need to be waterproof to ensure better reliability and lifespan.

[0038] In related technologies, connector female sockets achieve waterproof sealing by internal potting. However, due to process limitations, air bubbles and pores are prone to appearing inside the potting material, which not only weakens the sealing performance but also makes them susceptible to cracking and detachment during use, affecting the service life of the connector female socket. The production and maintenance costs of potting waterproof designs are relatively high, making it less than optimal for widely used and inexpensive connector female sockets.

[0039] In addition, the potting waterproof design is prone to glue overflow during the production process, which can contaminate the connector contacts and reduce the signal transmission power and charging efficiency of the connector socket.

[0040] To address the problems of the prior art, this application provides a waterproof structure and electronic device. The waterproof structure can achieve waterproof protection for the connector socket without the aid of potting compound, thereby extending the reliability and service life of the connector socket.

[0041] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of an electronic device according to an embodiment of this application; Figure 2 This is a schematic diagram of a waterproof structure according to an embodiment of this application; Figure 3 This is a schematic diagram of a waterproof structure according to an embodiment of this application; Figure 4 This is a schematic diagram of the structure of the housing according to an embodiment of this application; Figure 5 This is a schematic diagram of the structure of an isolation component according to an embodiment of this application.

[0042] The waterproof structure provided in the embodiments of this application will be described below. The waterproof structure provided in the embodiments of this application is applicable not only to connector females, but also to electronic devices including connector females.

[0043] Firstly, please refer to Figure 1 , Figure 2 and Figure 4This application provides a waterproof structure applied to a connector female socket 600. The waterproof structure includes a housing 100, a spacer 200, and an end cap 300. The housing 100 accommodates the connector female socket 600 and has an outer connecting portion 110, a stepped portion 120, and an inner connecting portion 130 arranged sequentially along its axial direction. The spacer 200 is fitted onto the outer connecting portion 110, and a first waterproof component 410 is sandwiched between the spacer 200 and the stepped portion 120. The first waterproof component 410 is capable of elastic deformation. The end cap 300 is fitted onto the outer connecting portion 110 and seals the housing 100, with the end cap 300 spaced apart from the housing 100 by the spacer 200. The end cap 300 is threadedly connected to the outer connecting portion 110. Rotating the end cap 300 moves the spacer 200 closer to the stepped portion 120, so that the first waterproof component 410 abuts against the spacer 200 and the stepped portion 120.

[0044] The first waterproof component 410 is capable of elastic deformation, meaning it can be compressed by the isolator 200 when the end cap 300 is tightened, and can also spring back to its original position after the pressure from the isolator 200 is removed by loosening the end cap 300, ready for the next tightening of the end cap 300 to seal the waterproof seal. Optionally, the first waterproof component 410 is made of at least one of foamed material, rubber, and silicone. For example, the first waterproof component 410 is a rubber gasket.

[0045] The external connection part 110 refers to the structure facing the power receiving element, and the internal connection part 130 refers to the structure facing the power supply element.

[0046] Optionally, in some embodiments, a fixing structure for fixing the connector female 600 is provided inside the housing 100; in other embodiments, the housing 100 is only used to accommodate the connector female 600, and the connector female 600 is fixed relative to the housing 100 by other components.

[0047] Therefore, the waterproof structure can seal one end of the housing 100 through the end cap 300 to prevent moisture from directly entering the housing 100. The waterproof structure also includes a first waterproof component 410 between the housing 100 and the end cap 300. When the end cap 300 closes onto the housing 100, it compresses the first waterproof component 410, causing it to overflow in a plane perpendicular to the thickness direction while simultaneously filling the gap between the end cap 300 and the housing 100, preventing moisture from entering the housing 100 through the gap and contaminating the connector socket 600. The waterproof structure also includes a spacer 200 between the end cap 300 and the first waterproof component 410. The spacer 200 can evenly apply the pressure of the end cap 300 to the first waterproof component 410 to improve the sealing effect of the first waterproof component 410, giving the waterproof structure uniform waterproof performance in the circumferential direction of the first waterproof component 410. In this embodiment, the end cap is threadedly connected to the outer connecting part 110 of the housing 100 so that the end cap 300 can still form a compression waterproofing effect on the first waterproof component 410 through the isolation member 200 after the external force of screwing is removed.

[0048] It is understood that the outer connecting part 110 is provided with an external thread for mating with the end cap 300. In order to reduce the seepage of water from the spiral groove of the external thread and its impact on the connector female 600, optionally, in some embodiments, the inner side of the first waterproof member 410 is provided with an internal thread that matches the external thread of the outer connecting part 110, so as to block the spiral groove of the outer connecting part 110 and prevent water flow; or, in other embodiments, the outer connecting part 110 is provided with a retention structure for accommodating the first waterproof member 410. The retention structure is located between the external thread and the step part 120. The first waterproof member 410 and the retention structure are interference-fitted to prevent water flow. The length of the retention structure along the axial direction of the housing 100 is the same as the thickness of the first waterproof member 410 when it is squeezed to the maximum, or the length of the retention structure along the axial direction of the housing 100 is less than the thickness of the first waterproof member 410 when it is squeezed to the maximum.

[0049] Please continue reading. Figure 1 and Figure 2 According to some embodiments of this application, a second waterproof component 420 is sandwiched between the end cap 300 and the spacer 200. The second waterproof component 420 is capable of elastic deformation. The end cap 300 is rotated to move closer to the spacer 200 so that the second waterproof component 420 abuts against the end cap 300 and the spacer 200.

[0050] The second waterproof component 420 is capable of elastic deformation, meaning it can be compressed by the isolator 200 when the end cap 300 is tightened, and can also spring back to its original position after the pressure from the isolator 200 is removed by loosening the end cap 300, ready for the next tightening of the end cap 300 to seal the waterproof seal. Optionally, the second waterproof component 420 is made of at least one of foamed material, rubber, and silicone. For example, the second waterproof component 420 is a rubber gasket.

[0051] Optionally, the second waterproof component 420 has the same structure as the first waterproof component 410, and the two can be interchanged during assembly to reduce assembly difficulty.

[0052] Therefore, the second waterproof component 420 can fill the gap between the end cap 300 and the separator 200, thereby further improving the waterproof performance of the waterproof structure and reducing the path of water infiltration.

[0053] Please continue reading. Figure 2 According to some embodiments of this application, the second waterproof component 420 includes a sealing part 421 and an anti-loss part 422 connected together. The sealing part 421 is sandwiched between the end cap 300 and the isolation member 200, and the anti-loss part 422 is connected to the end cap 300.

[0054] Therefore, the end cap 300 is connected to the second waterproof component 420 sleeved on the outer connection part 110 so that the end cap 300 can still be connected to the housing 100 after it is opened, thereby reducing the probability of the end cap 300 being lost and reducing the possibility of moisture entering the connector female 600 from the outer connection part 110 and contaminating it.

[0055] It is understood that in other embodiments, the end cap 300 is connected to other components of the waterproof structure to prevent loss, for example, the end cap 300 is connected to the isolator 200, or the end cap 300 is connected to the stepped portion 120 of the housing 100 to prevent loss.

[0056] Please see Figure 2 According to some embodiments of this application, the end cap 300 includes a fixing nut 320 and a cover body 310, a sealing part 421 is sandwiched between the fixing nut 320 and the spacer 200, and an anti-loss part 422 is connected to the cover body 310.

[0057] Optionally, the cover 310 is detachably connected to the retaining nut 320.

[0058] Optionally, the cover 310 is detachably connected to the outer connecting part 110, or the cover 310 is detachably connected to the spacer 200. Exemplarily, the cover 310 is threaded or snap-fit ​​connected to the outer connecting part 110.

[0059] Optionally, the end cap 300 further includes a clip 311, which is detachably connected to the cover body 310, and the anti-loss portion 422 of the second waterproof component 420 is sleeved on the clip 311, so as to realize the detachable connection between the second waterproof component 420 and the end cap 300, which facilitates the individual maintenance and replacement of the cover body 310 or the second waterproof component 420, and reduces the maintenance cost of the waterproof structure. For example, the clip 311 is made of insulating plastic.

[0060] Therefore, the end cap 300 separates the fixing nut 320 used to adjust the deformation of the first waterproof component 410 and the second waterproof component 420 and the cover body 310 used to seal the housing 100, so that after the cover body 310 is removed, the fixing nut 320 can still maintain the compression effect on the first waterproof component 410 and the second waterproof component 420 to achieve continuous waterproofing.

[0061] Please see Figure 1 According to some embodiments of this application, the end cap 300 further includes a sealing gasket 330 located inside the cover body 310. When the cover body 310 covers the outer connecting portion 110, the sealing gasket 330 abuts against the cover body 310 and the outer connecting portion 110.

[0062] Optionally, the sealing gasket 330 is made of polyethylene foam.

[0063] Therefore, the sealing gasket 330 can further reduce the gap between the cover 310 and the outer connection part 110 when the end cover 300 is closed, improve the sealing effect, and reduce the contamination of the connector female 600 in the outer connection part 110 by moisture and dust impurities.

[0064] Please continue reading. Figure 1 According to some embodiments of this application, a protrusion 312 is provided inside the cover 310, and a guide groove 111 is provided in the outer connecting part 110. An inlet is opened on the side of the guide groove 111 near the cover 310. The protrusion 312 enters the guide groove 111 through the inlet and moves along the guide groove 111 to achieve the closing of the cover 310 to the fixing nut 320.

[0065] Optionally, please refer to Figure 1 or Figure 4 The guide groove 111 is spirally arranged to guide the cover 310 to move closer to the outer connection part 110 during the process of closing, thereby squeezing the sealing gasket 330 to prevent water from seeping in.

[0066] Optionally, the outer connecting part 110 is also provided with anti-loosening teeth, which have an inclined surface and a stop surface. During the tightening of the cover 310, the protrusion 312 moves along the inclined surface and then falls. When the cover 310 is loosened, the protrusion 312 will first abut against the stop surface to form a prompt, which can remind the operator that the cover 310 is about to be opened, and can reduce the unexpected opening of the cover 310.

[0067] Therefore, the design of the protrusion 312 and the inlet can assist the cover 310 to connect with the outer connecting part 110, so as to reduce the misalignment of the cover 310 when it is sealed, improve the fit between the cover 310 and the outer connecting part 110, and thus improve the sealing effect and waterproof performance of the end cap 300.

[0068] Please see Figure 1 and Figure 3 According to some embodiments of this application, the waterproof structure also includes a limiting cover 500, which is detachably connected to the inner connecting portion 130. The limiting cover 500 has a connection window 501 to expose the connector female 600.

[0069] Optionally, the limit cover 500 may be made of insulating plastic.

[0070] Optionally, the limiting cover 500 is threadedly connected to the inner connecting portion 130 to adjust the size of the installation space jointly defined by the limiting cover 500 and the housing 100, thereby expanding the applicability of the connector female 600 installed inside. For example, the limiting cover 500 and the inner connecting portion 130 are connected by screws, or the limiting cover 500 and the inner connecting portion 130 are respectively provided with internal threads and external threads and screwed together.

[0071] Thus, the limiting cover 500 and the housing 100 together define the space for installing the connector female 600 and restrict the axial movement of the connector female 600 in the housing 100, thereby fixing the connector female 600. The limiting cover 500 and the housing 100 are detachably connected to facilitate the installation, removal and replacement of the connector female 600.

[0072] Please see Figure 1 According to some embodiments of this application, the limiting cover 500 is provided with a first guide structure 510, and the inner connecting part 130 is provided with a second guide structure 131, with the first guide structure 510 and the second guide structure 131 cooperating.

[0073] Optionally, the first guide structure 510 is one of the slide rail and the slide groove, and the second guide structure 131 is the other of the slide rail and the slide groove. The first guide structure 510 and the second guide structure 131 slide together to assist in the docking of the limiting cover 500 and the inner connecting part 130.

[0074] Optionally, the first guide structure 510 and the second guide structure 131 are two magnetic structures with opposite magnetic properties. When the limiting cover 500 is assembled into the inner connecting part 130, the first guide structure 510 and the second guide structure 131 are magnetically connected so that the limiting cover 500 rotates relative to the inner connecting part 130 to a specified posture.

[0075] Therefore, the first guide structure 510 and the second guide structure 131 can assist in the rapid docking of the limiting cover 500 and the inner connecting part 130, reducing the assembly difficulty of the waterproof structure and improving assembly efficiency. The first guide structure 510 and the second guide structure 131 also facilitate the docking of the connector female 600 and the connection window 501 on the limiting cover 500, exposing the connector female 600 to achieve the connection between the connector female 600 and the power supply component.

[0076] Please see Figure 5 According to some embodiments of this application, the isolation member 200 has a through hole for the external connection portion 110 to pass through, and the through hole is formed by at least the first side 201 and the second side 202.

[0077] Optionally, the first side 201 is an arc side, the second side 202 is an arc side, and the radii of the first side 201 and the second side 202 are set differently.

[0078] Optionally, the first side 201 is an arc side, and the second side 202 is a straight side.

[0079] Thus, the first side 201 can fit with the outer connecting part 110 of the housing 100, and the second side 202 can make line contact with the outer connecting part 110 of the housing 100. The second side 202 can prevent the outer connecting part 110 of the housing 100 from rotating relative to the through hole of the isolator 200, so as to achieve circumferential positioning of the housing 100 and the isolator 200, thereby reducing the unexpected rotation of the connector female 600 in the working state.

[0080] Secondly, please refer to Figure 1 This application provides an electronic device, which includes a connector female 600 and a waterproof structure provided in any of the embodiments of the first aspect described above. The connector female 600 is mounted on the housing 100 of the waterproof structure. Since the electronic device includes the waterproof structure of any of the aforementioned embodiments, it has all the beneficial effects of the aforementioned waterproof structure.

[0081] Optionally, the connector female 600 is one of a USB female, a Type C female, an HDMI female, or an RJ45 female.

[0082] Electronic devices can be mobile phones, tablets, laptops, handheld computers, in-vehicle devices, mobile internet devices, etc., or personal computers, televisions, ATMs or self-service machines, or devices such as sockets used to transmit electrical energy. The embodiments of this application do not specifically limit the scope.

[0083] It is understandable that the waterproof structure's isolation component 200 can be a separately set component and fixedly connected to the electronic device, or the electronic device's housing can be used directly as the isolation component 200.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
