[0073] Please refer toFigure 7 and Figure 8 In some embodiments, the end of the insertion portion 118 away from the first protruding portion 116 is flush with the end of the second main body portion 122 away from the third protruding portion 123, to ensure the overall aesthetics and structural balance of the hot shoe device 100. Such a design not only improves the appearance quality of the hot shoe device 100, but also ensures the protective effect of the insertion portion 118 on the second main body portion 122, and reduces stress concentration caused by structural unevenness, thereby improving the overall reliability and service life.

[0074] Referring to Figure 7 In some embodiments, the hot shoe device 100 further comprises a fastener 160, and the electrical connection assembly 130 further comprises a second electrical connection member 132, which can be an electrically conductive metal spring, to facilitate grounding when the first external device and the second external device are electrically connected through the hot shoe device 100. The surface of the second electrical connection member 132 can be plated to reduce signal loss and improve corrosion resistance. The side of the second main body portion away from the cover plate 141 is provided with a connecting column 1222, which can have a shape including but not limited to a cylindrical shape, a square shape, or other suitable shapes, to ensure stable fixation of the fastener 160. The first protruding portion 116 is provided with a mounting hole 1161, and the fastener 160 is configured to be able to pass through the mounting hole 1161 and be fixed to the connecting column 1222, so as to fix the second electrical connection member 132 to the first protruding portion 116. The edges of the mounting hole 1161 can be chamfered to reduce stress concentration and improve the durability of the structure. The design of the fastener 160 ensures the stability and reliability of the electrical connection assembly 130, and since the fastener 160 is fixed to the connecting column 1222 by passing through the mounting hole 1161, the arrangement of the fastener 160 also improves the connection reliability of the first bracket 110 and the second bracket 120.

[0075] Compared with the related art, in which a grounding metal spring is installed between an aluminum alloy terminal (nested in a plastic core) and a plastic core (used to install a metal contact pin, one end of which is electrically connected to the first external device, and the other end is electrically connected to the second external device), and locked by a screw, in the present application, the second electrical connection member 132 is fixed to the side of the first protruding portion 116 away from the first main body portion 115 by the fastener 160, so that the fixation of the second electrical connection member 132 is more convenient without repeated positioning.

[0076] It can be understood that in some embodiments, the fastener 160 can be made of various materials such as metal or high-strength plastic to ensure its structural strength and durability. The shape of the fastener 160 can be designed in the form of a screw, a buckle or a latch, etc. to adapt to different fixing needs. For example, the fastener 160 can be a screw with threads, which fixes the second electrical connector 132 on the first protruding part 116 and the connecting column 122 by screwing the screw.

[0077] Please refer to Figure 3 、 Figure 4 and Figure 10 In some embodiments, the side of the first protruding part 116 away from the first main part is provided with a first mounting column 1162 and a second mounting column 1163, the first mounting column 1162 and the second mounting column 1163 are arranged at both ends of the first protruding part 116 along a first direction X, the first direction X is perpendicular to the direction from the first protruding part 116 to the second protruding part 117, the second electrical connector 132 is provided with a first curled part 1321 and a second curled part 1322 at both ends along the first direction X, the first curled part 1321 is sleeved outside the first mounting column 1162, and the second curled part 1322 is sleeved outside the second mounting column 1163. The arrangement of the first mounting column 1162, the second mounting column 1163, the first curled part 1321 and the second curled part 1322 further improves the stable fixation of the second electrical connector 132. It should be noted that the sleeving of the first curled part 1321 outside the first mounting column 1162 and the sleeving of the second curled part 1322 outside the second mounting column 1163 can effectively position the second electrical connector 132, prevent excessive relative movement of the second electrical connector 132 relative to the first protruding part 116, and thus facilitate the fixation of the fastener 160 to the first protruding part 116, further improving the assembly efficiency.

[0078] It can be understood that in some embodiments, the materials of the first mounting column 1162 and the second mounting column 1163 can be the same as those of the first support 110, such as aluminum alloy or stainless steel, to ensure their structural strength and corrosion resistance. The shape of the first mounting column 1162 and the second mounting column 1163 can be designed in a cylindrical, square or other suitable shape to adapt to the curled part of the second electrical connector 132. For example, the first mounting column 1162 and the second mounting column 1163 can be designed in a cylindrical shape to facilitate the sleeving of the curled part of the second electrical connector 132.

[0079] The shape of the second electrical connector 132 can be designed in a flat strip or a circular line to adapt to the shape of the first mounting column 1162 and the second mounting column 1163. For example, the second electrical connector 132 can be designed in a flat strip with curled parts at both ends to facilitate the sleeving on the first mounting column 1162 and the second mounting column 1163.

[0080] The design of the first curling part 1321 and the second curling part 1322 can be diversified, for example, it can be single-layer curling or multi-layer curling, to ensure its firm connection with the first mounting column 1162 and the second mounting column 1163. The surface of the first curling part 1321 and the second curling part 1322 can be smoothed to reduce the friction with the first mounting column 1162 and the second mounting column 1163, and improve the convenience of installation. In addition, the surface of the first mounting column 1162 and the second mounting column 1163 can be treated to prevent slipping, increasing the friction of the curling part of the second electrical connector 132, preventing it from being too loose. The root of the first mounting column 1162 and the second mounting column 1163 can be provided with a reinforcing rib to improve its structural strength and prevent it from breaking due to external force.

[0081] Please refer to Figure 3 and Figure 14 In some embodiments, the second electrical connector 132 further includes a first elastic sheet 1323 and a second elastic sheet 1324 extending in the direction indicated by the first protruding part 116 to the second protruding part 117, the first elastic sheet 1323 and the second elastic sheet 1324 are oppositely arranged along the first direction X, and one end of the first elastic sheet 1323 is connected to the first curling part 1321, and one end of the second elastic sheet 1324 is connected to the second curling part 1322. When the hot shoe device 100 is connected to the first external device, the first elastic sheet 1323 and the second elastic sheet 1324 can be locally deformed under the extrusion of the first bracket 110 and the first external device, thereby increasing the contact area of the second electrical connector 132 with the first bracket 110 and the first external device, and further ensuring the reliability and stability of the electrical connection. The surface of the first elastic sheet 1323 and the second elastic sheet 1324 can be treated to prevent oxidation, improve its corrosion resistance, and prolong its service life.

[0082] It can be understood that in some embodiments, the material of the first elastic sheet 1323 and the second elastic sheet 1324 can be selected from materials with good electrical conductivity and elasticity, including but not limited to phosphor bronze or beryllium copper, to ensure its reliability and durability in long-term use. The shape of the first elastic sheet 1323 and the second elastic sheet 1324 can be designed as a flat circular arc strip (i.e., the first elastic sheet 1323 and the second elastic sheet 1324 are both provided with a curved part), and the two ends are respectively connected to the first curling part 1321 and the second curling part 1322, and the curved part can increase the contact area and pressure. Thus, the reliability of the electrical connection is ensured.

[0083] Specifically, the first elastic sheet 1323 is provided with a first bending part 1325 at one end away from the first curling part 1321, which bends away from the second elastic sheet 1324, the second elastic sheet 1324 is provided with a second bending part 1326 at one end away from the second curling part 1322, which bends away from the first elastic sheet 1323, the first bending part 1325 and the second bending part 1326 are configured to be in contact with the first external device. When the hot shoe device 100 is connected to the first external device, the first bending part 1325 and the second bending part 1326 are extruded by the first external device and the first support 110, so that the bending degree is reduced (i.e. the bending radius is increased), and under the influence of the material properties of the first bending part 1325 and the second bending part 1326, the first bending part 1325 and the second bending part 1326 have a tendency to change from a flat state (a state with a large bending radius) to a bending state (a state with a small bending radius), which enables the first bending part 1325 and the second bending part 1326 to be closely contacted with the first support 110 and the first external device, ensuring the reliability of the connection. At the same time, the first bending part 1325 and the second bending part 1326 can also increase the contact area with the first support 110 and the first external device, thereby improving the conductive effect.

[0084] The design of the first bending part 1325 and the second bending part 1326 of the first elastic sheet 1323 can be diversified, for example, it can be one-way bending or two-way bending, to ensure the contact effect with the first external device. The surface of the first bending part 1325 and the second bending part 1326 can be smoothed to reduce the friction with the first external device, improve the stability and reliability of the contact.
