[0031] In this embodiment, please refer to Figure 3. Figure 4 The protective shell 11 is designed with a square structure. The first shell 111 is a cover-like structure with open sides, and the second shell 112 is an L-shaped cover-like structure. The second shell 112 is connected to the adjacent open sides of the first shell 111, making installation and disassembly convenient. A groove 1111 is provided on one outer side wall of the first shell 111, and the third shell 113 is installed in the groove 1111. The connecting terminal 12 passes through the first shell 111 and the third shell 113 in sequence and is connected to the camera 21. The structure is compact and the connection is more stable.

[0032] Specifically, the lengths of the first housing 111, the second housing 112, and the third housing 113 are all less than the length of the corresponding side of the camera 21, resulting in a compact structure that is easy to carry.

[0033] In this embodiment, the third housing 113 is configured as a plate-like structure. The outer periphery of the third housing 113 is fitted to the inner wall of the groove 1111. A first sealing block 1134 and a second sealing block 1135 protrude from the end of the third housing 113 facing the camera 21. Both the first sealing block 1134 and the second sealing block 1135 have concave receiving surfaces 1136 on their sides facing the camera 21. The receiving surfaces 1136 are arc-shaped. The outer rounded corner of the camera 21 is fitted to the receiving surfaces 1136 of the first sealing block 1134 and the second sealing block 1135 to cover the outer rounded corner of the camera 21, making the third housing 113 fit more tightly with the outer surface of the camera 21, the connection more reliable, and also providing waterproof and dustproof functions, extending the service life.

[0034] To further improve the stability of the installation of the first housing 111 and the third housing 113, at least one third locking block 1137 is provided at each end of the side of the third housing 113 facing the first housing 111, and a third locking groove is provided on the first housing 111 at the position corresponding to the third locking block 1137, and the third locking block 1137 is locked in the corresponding third locking groove.

[0035] Please refer to Figure 1 , Figure 3 , Figure 4The third housing 113 has a protruding fixing part 1131. At least one end of the fixing part 1131 has a through first slot 1132. A first locking block 1133 is disposed within the first slot 1132. One end of the first locking block 1133 near the first housing 111 is fixed to the inner wall of the first slot 1132, and the other end of the first locking block 1133 protrudes from the first slot 1132 and is spaced apart from the side of the fixing part 1131. The fixing part 1131 and the first locking block 1133 cooperate to fix the camera 21 in the corresponding fixing slot 211, improving the stability of the connection between the expansion connector 1 and the camera 21 and making it more convenient to use. A first locking seat 1113 is disposed within the groove 1111 corresponding to the first slot 1132. The first locking seat 1113 is engaged within the first slot 1132, making reasonable use of space and facilitating the fixing of the first housing 111 and the third housing 113. Specifically, both ends of the fixing part 1131 are provided with a first slot 1132 and a first block 1133 structure, which makes it easy to keep the connecting terminal 12 centered during installation and balance the force on both sides. This can prevent the connecting terminal 12 from tilting due to the force on one side of the fixing part 1131, which would cause damage to the connecting terminal 12.

[0036] The outer periphery of the groove 1111 protrudes from the third housing 113, and the outer periphery of the groove 1111 is sealed and fitted with the outer side of the camera 21, further improving the fit and sealing performance.

[0037] Furthermore, a number of through-holes 114 are provided on the side wall of the end of the groove 1111 that corresponds to the heat dissipation area of ​​the camera 21. The heat dissipation holes 114 are elongated and inclined to increase the heat dissipation area and improve the heat dissipation efficiency.

[0038] In this embodiment, please refer to Figure 3 The inner periphery of the second housing 112 is provided with multiple second retaining seats 1121 at intervals. Each second retaining seat 1121 has a second retaining groove 1122 on the side facing the first housing 111. The first housing 111 is correspondingly provided with a second retaining block 1112, which engages within the second retaining groove 1122, forming a snap-fit ​​connection. This design is simple, easy to install and disassemble, and has low cost. Specifically, each inner side of the second housing 112 has two second retaining seats 1121 at intervals, resulting in a more secure installation.

[0039] Each side of the second housing 112 is provided with at least one limiting block 1123. The limiting block 1123 is configured with an inverted L-shaped structure. One end of the limiting block 1123 is fixedly connected to the inner side wall of the second housing 112, and the other end of the limiting block 1123 is set towards the second locking block 1112. It is used to limit the depth of the second locking block 1112 locked in the second locking groove 1122, which helps to protect the structure and prevent excessive pressing from damaging the second locking block 1112 or the second locking seat 1121.

[0040] Please refer to Figure 5 , Figure 6 In this embodiment, the camera assembly 2 includes a camera 21 and any of the aforementioned expansion connectors 1. A connector plug 212 is provided on one side of the camera 21, and the connector terminal 12 of the expansion connector 1 is electrically connected to the connector plug 212.

[0041] The connecting terminal 12 is aligned with the connecting plug 212, and then the connecting terminal 12 is pressed into the connecting plug 212 to achieve communication connection between the expansion connector 1 and the camera 21. The fixing part 1131 on the third housing 113 is interference-fitted into the fixing groove 211 through the first locking blocks 1133 at both ends, improving the stability of the connection. The heat generated by the camera 21 can be dissipated through the heat dissipation holes 114 on the first housing 111.

[0042] In this embodiment, the present invention relates to an expansion connector and its corresponding camera assembly. The expansion connector includes a protective shell, connecting terminals, an adapter unit, and an adapter control circuit. The protective shell includes a first shell, a second shell, and a third shell. The first shell and the second shell are detachably connected to form a cavity for mounting the adapter control circuit. The third shell is detachably connected to the side of the first shell facing the camera for fixed connection with the camera. The connecting terminals are disposed on one side of the first shell, and one end of the connecting terminals is connected to the camera. The adapter unit includes a network interface, an audio interface, a charging interface, and a data interface. The network interface, audio interface, charging interface, and data interface are spaced apart on the periphery of the protective shell. The adapter control circuit is disposed inside the protective shell, and the connecting terminals and the adapter unit are electrically connected to the adapter control circuit. This expansion connector allows for quick assembly by disassembling the protective shell into a first shell, a second shell, and a third shell. The connection terminals connect the adapter control circuitry to the camera, enabling communication between the expansion connector and the camera. The protective shell features network, audio, charging, and data interfaces on its periphery, increasing the camera's interface count and allowing multiple devices to connect simultaneously. This provides strong compatibility and ease of use. Camera components using this expansion connector can also connect simultaneously to multiple devices, offering strong compatibility and ease of use. This solves the problem of poor compatibility caused by the limited number of interfaces on existing cameras, which prevents multiple functions from being used simultaneously.

[0043] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
