Description

Technical Field

[0001] This application relates to the field of surveillance equipment technology, and in particular to a charging structure for a camera. Background Technology

[0002] USB Type-C is a USB interface standard that is smaller than both Type-A and Type-B. It can be used in both PCs (host devices) and external devices. Typically, a Type-C interface consists of a female connector and a male connector. The female connector is mounted on the terminal, and the male connector is mounted on the cable. Signal transmission is achieved through the plugging and unplugging of the male and female connectors.

[0003] In related technologies, the mating of female and male connectors presents issues with waterproofing and inconvenience in assembly and disassembly. This is particularly problematic when used in cameras, which are typically used outdoors. Poor waterproofing can lead to internal water leakage, affecting the camera's normal operation. Furthermore, because cameras are often used outdoors, they require regular maintenance, necessitating frequent plugging and unplugging of the male and female connectors. Using screws for fixing makes this extremely inconvenient. Utility Model Content

[0004] Therefore, it is necessary to provide a charging structure for cameras that, while satisfying the power connection requirements, not only improves the waterproof performance at the interface between the plug and the camera, but also facilitates quick assembly and disassembly of the plug and socket.

[0005] A charging structure for a camera includes a housing, a socket mounted on the housing, and a plug that engages with the socket. The plug is connected to a cable for connecting to a power source. The housing has a mounting hole for mounting the socket and a mounting portion surrounding the mounting hole. The socket does not protrude from the mounting hole. A sealing portion is provided within the mounting hole. The plug and / or the sealing portion has a first sealing element that can be pressed between the plug and the sealing portion when the plug is inserted into the socket. One of the plug and the mounting portion has a latching protrusion, and the other has a latching arm that can engage with the latching protrusion.

[0006] Understandably, when the plug and socket are connected, the first seal can be pressed between the sealing part and the plug within the mounting hole, ensuring a tight seal at the connection between the plug and the camera. When rainwater drips onto the plug, the first seal reduces the amount of water seeping in between the plug and the camera, significantly improving waterproofing. Furthermore, the sealing part within the mounting hole allows the plug to be partially housed within it, preventing the first seal from being exposed and reducing the risk of water contact, further enhancing waterproofing. Simultaneously, the mounting hole is surrounded by a mounting part that engages with the plug via a snap-fit ​​arm and a snap-fit ​​protrusion. This design locks the plug to the camera housing after connection, improving connection reliability. Moreover, the snap-fit ​​arm and snap-fit ​​protrusion facilitate quick installation and removal of the plug from the housing; when the camera requires maintenance, the locking mechanism can be released, allowing the plug to be unplugged.

[0007] In some embodiments, the snap-fit ​​arm includes an arm body and a connecting portion connected to the arm body. The connecting portion divides the arm body into a snap-fit ​​portion and an operating portion. The snap-fit ​​portion and the operating portion are capable of moving in opposite directions around the connecting portion. The snap-fit ​​portion engages with the mounting portion. The operating portion is capable of driving the snap-fit ​​portion to swing relative to the connecting portion. The connecting portion is connected to the plug or the mounting portion.

[0008] In some embodiments, the assembly portion or the plug has a limiting protrusion, and the operating portion can abut against the limiting protrusion to limit the tilting angle of the snap-fit ​​portion.

[0009] In some embodiments, the connecting portion is recessed on both sides along the axial direction of the plug with deformation grooves.

[0010] In some embodiments, the length of the latching portion is greater than the length of the operating portion, and / or the latching portion and the operating portion are set at an angle.

[0011] In some embodiments, the housing has an assembly cavity, a portion of the sidewall of the housing is recessed toward the assembly cavity to form an assembly groove, the assembly hole penetrates the assembly groove and communicates with the assembly cavity, and the assembly part protrudes from the bottom of the assembly groove and surrounds a portion of the assembly hole.

[0012] In some embodiments, the mounting hole includes a first section and a second section, the diameter of the second section being larger than that of the first section, the end face of the second section facing the first section forming the sealing portion, a portion of the socket passing through the first section, and a second sealing element being pressed between the socket and the first section.

[0013] In some embodiments, the mounting hole further includes a third segment connected between the first segment and the second segment, the diameter of the third segment being smaller than that of the first segment, and a limiting end face being provided between the third segment and the first segment, the limiting end face being able to abut against the socket to limit the displacement of the socket along the axial direction of the mounting hole.

[0014] In some embodiments, the latch protrusion is provided on the assembly portion, and the latch protrusion has a guide slope on the side facing the plug along the axial direction of the assembly hole.

[0015] In some embodiments, the snap protrusion protrudes radially outward along the mounting hole and is arranged in a ring shape. Multiple snap-fit ​​arms are provided and arranged at intervals along the circumference of the mounting hole. All of the multiple snap-fit ​​arms can engage with the snap protrusion.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 6 One embodiment of this application provides a charging structure for a camera, including a housing 10, a socket 20 mounted on the housing 10, and a plug 30 that engages with the socket 20. The plug 30 is connected to a cable 70 for connecting to a power source. The housing 10 has a mounting hole 101 for mounting the socket 20 and a mounting portion 102 surrounding the mounting hole 101. The socket 20 does not protrude from the mounting hole 101. A sealing portion 103 is provided within the mounting hole 101. The plug 30 has a first sealing member 41, which is pressed between the plug 30 and the sealing portion 103 when the plug 30 is inserted into the socket 20. One of the plug 30 and the mounting portion 102 has a latching protrusion 52, and the other has a latching arm 51, which engages with the latching protrusion 52. For example, the plug 30 may have a snap-fit ​​arm 51 and the assembly part 102 may have a snap-fit ​​protrusion 52; or the plug 30 may have a snap-fit ​​protrusion 52 and the assembly part 102 may have a snap-fit ​​arm 51.

[0033] The housing 10 is the camera's housing, and it surrounds an assembly cavity 104 for mounting the camera's internal imaging components. A circuit board 60 is also housed within the assembly cavity 104. A socket 20 is electrically connected to the circuit board 60, and the circuit board 60 is electrically connected to the imaging components. When the plug 30 is inserted into the socket 20, the circuit board 60 is connected to a power source, thereby supplying power to the camera and ensuring the normal operation of the imaging components. The camera can be used for surveillance and other purposes, such as capturing video footage.

[0034] Since cameras are mostly used in outdoor scenes, if the waterproofing at the connector 30 is not good, water can easily seep into the assembly cavity 104, causing damage to the circuit board 60.

[0035] In one embodiment of this application, a charging structure for a camera is provided, in which the mounting hole 101 communicates with the mounting cavity 104, and a portion of the socket 20 passes through the mounting hole 101. This not only ensures electrical connection between the socket 20 and the circuit board 60 within the mounting cavity 104, but also ensures that the end of the socket 20 facing away from the circuit board 60 is exposed, facilitating insertion and mating with the plug 30. Furthermore, since the socket 20 does not protrude from the mounting hole 101, the wall of the mounting hole 101 and the socket 20 act as a shield, reducing the risk of the socket 20 coming into contact with water. The plug 30 is provided with a first sealing member 41. When the plug 30 and the socket 20 are inserted and mated, the first sealing member 41 can be pressed between the sealing part 103 within the mounting hole 101 and the plug 30, ensuring the sealing of the connection between the plug 30 and the camera. When rainwater drips onto the plug 30, the first seal 41 reduces the amount of water seeping between the plug 30 and the camera, significantly improving the waterproofing effect. Furthermore, the sealing part 103 within the mounting hole 101 allows part of the plug 30 to be accommodated within it, preventing the first seal 41 from being exposed and reducing the risk of water contact, further enhancing the waterproofing effect. Simultaneously, a mounting part 102 is provided around the mounting hole 101, which engages with the plug 30 via a snap-fit ​​arm 51 and a snap-fit ​​protrusion 52. This design locks the plug 30 to the camera housing 10 after it is plugged into the socket 20, improving the connection reliability. Moreover, the engagement of the snap-fit ​​arm 51 and the snap-fit ​​protrusion 52 facilitates quick assembly and disassembly of the plug 30 relative to the housing 10. When the camera requires maintenance, the locking relationship can be released, and the plug 30 can be unplugged. Moreover, because the assembly part 102 is located around the assembly hole 101, the limiting of the plug 30 and the housing 10 will not interfere with the sealing of the plug 30 and the sealing part 103, thus ensuring the assembly reliability of the first sealing member 41 and maintaining better sealing performance.

[0036] like Figures 2 to 4 As shown, the plug 30 includes a conductive part 31 and a plastic shell 32 connected to the conductive part 31. The plastic shell 32 covers the outside of the conductive part 31, and a portion of the conductive part 31 protrudes from the plastic shell 32 for insertion into the socket 20. The conductive part 31 is connected to the cable 70. A first socket is provided at the end of the conductive part 31 protruding from the plastic shell 32, and the socket 20 is provided with a second socket, which contains a tongue. The conductive part 31 is inserted into the second socket, and the tongue is inserted into the first socket, thus satisfying the insertion and mating of the plug 30 and the socket 20.

[0037] like Figures 2 to 4As shown, in some specific embodiments, the first sealing element 41 is a sealing ring, which can be sleeved on the outside of the conductive part 31 and disposed near the plastic housing 32. When the plug 30 and the socket 20 are plugged in, the first sealing element 41 is pressed between the sealing part 103 and the end of the plastic housing 32 facing the conductive part 31. The first sealing element 41 and the conductive part 31 are also sealed. For example, an arc-shaped groove is recessed on the outer wall of the conductive part 31 near the plastic housing 32 to facilitate the installation of the first sealing element 41.

[0038] In other embodiments, the first sealing element 41 may be disposed on the sealing portion 103. The sealing portion 103 may have an arc-shaped groove recessed therein, with a portion of the first sealing element 41 housed within the groove and fixed with adhesive. Alternatively, the first sealing element 41 may be provided on both the sealing portion 103 and the plug 30, utilizing the press-fitting of the two first sealing elements 41 to improve the sealing effect.

[0039] Please see Figures 2 to 6 In some embodiments, the snap-fit ​​arm 51 includes an arm body 511 and a connecting portion 512 connected to the arm body 511. The connecting portion 512 divides the arm body 511 into a snap-fit ​​portion 5111 and an operating portion 5112. The snap-fit ​​portion 5111 and the operating portion 5112 are capable of moving in opposite directions around the connecting portion 512. The snap-fit ​​portion 5111 engages with the assembly portion 102. The operating portion 5112 can drive the snap-fit ​​portion 5111 to swing relative to the connecting portion 512. The connecting portion 512 is connected to the plug 30 or the assembly portion 102.

[0040] Taking the snap-fit ​​arm 51 located on the plug 30 as an example, the snap-fit ​​protrusion 52 is provided with an assembly portion 102. The connecting portion 512 connects to the plug 30 to satisfy the fixation of the snap-fit ​​arm 51 relative to the plug 30. Taking the axial direction of the plug 30 as... Figures 2 to 6 Taking the left-right direction as an example, the plug 30 moves to the left to engage with the socket 20. As the plug 30 moves to the left, the locking part 5111 contacts the locking protrusion 52 and is pushed up radially by the locking protrusion 52 until the locking part 5111 passes over the locking protrusion 52 and is locked on the side of the locking protrusion 52 away from the connecting part 512. In this way, the locking arm 51 and the locking protrusion 52 are engaged. When the plug 30 is pulled out, pressing the operating part 5112 close to the outer wall of the plug 30 can cause the locking part 5111 to lift up to release the locking limit with the locking protrusion 52, and then the plug 30 is moved to the right.

[0041] In actual use, the plug 30 has a limiting protrusion 53, and the operating part 5112 can abut against the limiting protrusion 53 to limit the tilting angle of the locking part 5111. This setting can ensure that the locking part 5111 tilts within a certain safe angle, reducing the risk of excessive deformation of the locking part 5111; moreover, this setting can also prevent the locking part 5111 from colliding with other structures on the housing 10, improving the protection of the locking part 5111.

[0042] The upward tilt angle is the angle at which the snap-fit ​​portion 5111 tilts upward relative to the snap-fit ​​protrusion 52 around the connecting portion 512.

[0043] like Figure 4 and Figure 6 As shown, furthermore, the connecting portion 512 has deformation grooves 5121 recessed on both sides along the axial direction of the plug 30. The deformation grooves 5121 allow the connecting portion 512 to deform accordingly, accommodating the opposite movements of the locking portion 5111 and the operating portion 5112. The deformation grooves 5121 can be arc-shaped to minimize stress concentration. The locking arm 51 is made of hard plastic and has a certain deformation capacity.

[0044] In actual use, the locking part 5111 tilts upward relative to the connecting part 512 under the action of the locking protrusion 52, and the operating part 5112 moves downward relative to the connecting part 512 in sync. After the locking part 5111 passes the locking protrusion 52, it can move downward relative to the connecting part 512 to engage with the locking protrusion 52, and the operating part 5112 moves upward in sync to return to its original position.

[0045] In other embodiments, the connecting part 512 may be hinged to the plug 30, and a torsion spring is installed on the hinge axis to ensure that the snap-fit ​​part 5111 always needs to move toward the plug 30.

[0046] Please see Figures 1 to 6 In some embodiments, the length of the latching portion 5111 is greater than the length of the operating portion 5112. This arrangement causes the lever arm of the latching portion 5111 relative to the connecting portion 512 to be greater than the lever arm of the operating portion 5112 relative to the connecting portion 512. Therefore, under the same operating force, the movement distance of the latching portion 5111 relative to the connecting portion 512 is greater than the movement distance of the operating portion 5112 relative to the connecting portion 512. Especially when unlocking the latching portion 5111 via the operating portion 5112, a larger displacement of the latching portion 5111 can be achieved with a smaller displacement of the operating portion 5112, resulting in smooth unlocking. Simultaneously, this arrangement also makes the latching portion 5111 more stable during the latching process, improving the reliability and durability of the electrical connection structure.

[0047] Alternatively, the lengths of the latching portion 5111 and the operating portion 5112 can be the same, or the length of the latching portion 5111 can be shorter than the length of the operating portion 5112. The only requirement is that the latching portion 5111 and the latching protrusion 52 can be properly engaged and easily disengaged.

[0048] Furthermore, the engaging portion 5111 and the operating portion 5112 are angled together. This arrangement facilitates the release of the engaging portion 5111 from the locking protrusion 52 using the operating portion 5112, making operation easier. Alternatively, the axis of the engaging portion 5111 along its length direction can coincide with the axis of the operating portion 5112 along its length direction. This is merely an example.

[0049] Please see Figures 2 to 8 In some embodiments, the housing 10 is provided with an assembly cavity 104. A portion of the sidewall of the housing 10 is recessed towards the assembly cavity 104 to form an assembly groove 105. An assembly hole 101 penetrates the assembly groove 105 and connects to the assembly cavity 104. An assembly part 102 protrudes from the groove wall of the assembly groove 105 and surrounds a portion of the assembly hole 101. In other words, the assembly groove 105 provides sufficient space for the engagement of the snap-fit ​​arm 51 and the snap-fit ​​protrusion 52, and also protects them from interference from other structures in the external environment, further maintaining the stability of the snap-fit ​​engagement between the snap-fit ​​arm 51 and the snap-fit ​​protrusion 52, and enhancing the stability of the plug-in engagement between the plug 30 and the socket 20. Moreover, because the assembly groove 105 is recessed in the housing 10 and the assembly hole 101 is located in the groove wall of the assembly groove 105, the socket 20 can be assembled closer to the assembly cavity 104, reducing the connection distance between the socket 20 and the circuit board 60 while preventing the socket 20 from being exposed. The assembly part 102 is arranged in a ring shape, surrounding a portion of the wall of the assembly hole 101. The outer wall of the assembly part 102 protrudes radially outward with a locking protrusion 52. The arrangement of the assembly part 102 extends the length of the assembly hole 101, which facilitates the insertion of a portion of the plug 30 into the assembly hole 101, thereby improving the protective effect.

[0050] The latching protrusion 52 has a guide slope 521 on the side facing the plug 30 along the axial direction of the mounting hole 101. The guide slope 521 facilitates the engagement of the guide arm 51 over the latching protrusion 52. Correspondingly, the end of the latching arm 51 with the latching part 5111 facing away from the operating part 5112 has a hook 513, which engages with the latching protrusion 52. The hook 513 includes a first slope 5131, a first plane 5132, and a second plane 5133 connected in sequence. The first plane 5132 is arranged along the axial direction of the mounting hole 101, and the second plane 5133 is arranged along the radial direction of the mounting hole 101. During the snap-fit ​​process, the first inclined surface 5131 can cooperate with the guide inclined surface 521 to facilitate the snap hook 513 passing over the snap protrusion 52. The first flat surface 5132 can press against the outer wall of the assembly part 102, and the second flat surface 5133 abuts against and limits the snap protrusion 52 at one end face facing the assembly cavity 104 (i.e., the side facing away from the plug 30 along the axial direction of the assembly hole 101). The use of surface contact enhances the reliability of the connection. The assembly part 102 also has a step that connects to the snap protrusion 52, and the step surface along the axial direction of the assembly hole 101 cooperates with the first flat surface 5132.

[0051] like Figure 4 , Figure 6 and Figure 8 As shown, in some embodiments, the assembly hole 101 includes a first segment 1011 and a second segment 1012. The diameter of the second segment 1012 is larger than that of the first segment 1011, and a sealing portion 103 is formed on the end face of the second segment 1012 facing the first segment 1011. A portion of the socket 20 passes through the first segment 1011, and a second sealing member 42 is pressed between the socket 20 and the first segment 1011. That is, the assembly hole 101 is provided as a stepped hole, and the second segment 1012 can pass through the portion surrounded by the aforementioned assembly portion 102. At the same time, the second sealing member 42 can satisfy the assembly sealing between the socket 20 and the housing 10, preventing water seepage. The second sealing member 42 can be sleeved on the outside of the socket 20 or fixed to the first segment 1011 of the assembly hole 101.

[0052] like Figures 7 to 9 As shown, specifically, the socket 20 includes a socket body 21 and a housing 22 connected to the socket body 21. The socket body 21 protrudes from the housing 22 at one end axially towards the plug 30 along the mounting hole 101 and has a mounting protrusion 211 protruding radially outward. A second sealing ring is fitted onto the end of the socket body 21 protruding from the housing 22 and located on the side of the mounting protrusion 211 facing away from the plug 30. The second sealing member 42 is pressed between the hole wall of the first section 1011 and the outer wall of the socket body 21, and the mounting protrusion 211 limits the second sealing member 42, preventing it from detaching from the socket body 21. The end face of the first sealing member 41 can also be pressed into the mounting protrusion 211 to increase the sealing area and improve the sealing performance.

[0053] The second seal 42 is a sealing ring.

[0054] like Figure 4 , Figure 6 and Figure 8 As shown, the assembly hole 101 further includes a third segment 1013 connected between the first segment 1011 and the second segment 1012. The diameter of the third segment 1013 is smaller than the diameter of the first segment 1011. The end face of the first segment 1011 facing the third segment 1013 forms a limiting end face 1014. The limiting end face 1014 can abut against the socket 20 to limit the displacement of the socket 20 along the axial direction of the assembly hole 101. Specifically, the limiting end face 1014 abuts against the assembly protrusion 211 on the socket body 21 to limit the socket 20 from protruding from the assembly hole 101 and improve assembly safety.

[0055] In some embodiments, the latching protrusion 52 protrudes radially outward along the mounting hole 101 and is arranged in a ring shape. Multiple latching arms 51 are provided and arranged at circumferential intervals along the mounting hole 101, and all multiple latching arms 51 can engage with the latching protrusion 52. This arrangement ensures a wide circumferential engagement range, and the use of multiple latching arms 51 significantly improves connection reliability.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
