These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0029] Furthermore, 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 indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Please see Figures 1 to 10This embodiment provides a photographic accessory connection device 100, which includes an accessory body 10 and a hot shoe assembly 20. The hot shoe assembly 20 is disposed at the bottom of the accessory body 10 and is used to connect to the hot shoe slot of a camera.

[0031] The hot shoe assembly 20 includes a base 21, a signal transmitter 22, and a front cover 23. The base 21 is connected to the bottom of the accessory body 10 and has a mounting cavity 210 with a side opening. The signal transmitter 22 is disposed within the mounting cavity 210, and its bottom surface has multiple electrical contacts 2223 for electrical connection with the hot shoe contacts on the camera. The front cover 23 is fixed to the side of the signal transmitter 22 facing away from the base 21 and is detachably connected to the base 21 to secure the signal transmitter 22 between the front cover 23 and the base 21. At this time, the electrical contacts 2223 on the bottom surface of the signal transmitter 22 extend from the side edge of the base 21 to abut against the contacts in the hot shoe groove of the camera.

[0032] Specifically, the accessory body 10 can be a main structure such as a flash, video light, flash trigger, microphone, adapter, etc., and the hot shoe assembly 20 can be connected to the bottom of the accessory body 10 by screws, magnets, or snap-fit. In this embodiment, the accessory body 10 may include an upper shell 11, a bottom shell 12, and circuit boards 13, capacitors 14, and flash elements, etc., disposed within the upper shell 11 and the bottom shell 12. The hot shoe assembly 20 can be fixed to the bottom of the bottom shell 12 of the accessory body 10 to connect with the hot shoe slot on the camera, realizing the electrical connection between the accessory body 10 and the camera.

[0033] The base 21 and front cover 23 can be made of high-strength metal to ensure structural stability during repeated insertion and removal from the camera's hot shoe. The base 21 has a side-opening mounting cavity 210, which facilitates direct side mounting of the signal transmission component 22, thereby effectively improving assembly efficiency. When the signal transmission component 22 is housed within the mounting cavity 210 of the base 21, the electrical contacts 2223 on the bottom surface of the signal transmission component 22 extend from the side edge of the base 21, allowing the electrical contacts 2223 to contact the camera's hot shoe contacts, achieving precise alignment and conductivity, thereby enabling signal transmission between the accessory body 10 and the camera.

[0034] The front cover 23 is fixed to the side of the signal transmission component 22 away from the base 21 and is detachably snapped into the base 21. After the signal transmission component 22 is housed within the mounting cavity 210 of the base 21, the front cover 23 is aligned with the base 21, thus securely clamping the signal transmission component 22 between them. This prevents the signal transmission component 22 from shifting due to vibration or external force during use. This clamping and fixing method eliminates the need for additional gluing or welding, facilitating assembly and disassembly while reducing manufacturing complexity.

[0035] Please see Figure 3 and Figure 7 In some embodiments, the base 21 includes a base plate 211, a body 212, and two side plates 213. The body 212 is disposed on the base plate 211, and the two side plates 213 are respectively disposed on both sides of the body 212; the base plate 211, the body 212, and the side plates 213 together form a semi-closed mounting cavity 210 with side openings.

[0036] Specifically, the base 21 can be made of metal, with the base plate, main body 212, and two side plates 213 integrally formed to ensure stability during repeated insertion and removal from the camera's hot shoe. The bottom surface of the main body 212 is fixed to the base plate 211, and the top surface of the main body 212 is connected to the bottom shell 12 of the accessory body 10. The side plates 213 are located on both sides of the main body 212, thus forming an "L"-shaped semi-enclosed mounting cavity 210. The shape of the signal transmission component 22 matches the inner wall of the mounting cavity 210, allowing the signal transmission component 22 to fit snugly against the inner wall of the mounting cavity 210 after insertion, thereby forming an effective constraint and preventing loosening or displacement under vibration or external force.

[0037] like Figure 3 and Figure 5 As shown, the signal transmission component 22 can enter the mounting cavity 210 along the opening direction of the base body 212, and then the front cover 23 and the base 21 are clamped together to clamp the signal transmission component 22. The entire installation process is simple and convenient, which significantly improves assembly efficiency and ease of subsequent maintenance, effectively balancing the structural strength and assembly convenience of the hot shoe assembly 20.

[0038] Please see Figures 5 to 7 In some embodiments, the side plate 213 is provided with a first locking block 2131, which extends toward the side opening of the mounting cavity 210. The front cover 23 is provided with first slots 231 on both sides that match the first locking block 2131, and the first locking block 2131 can be inserted into the first slots 231 so that the front cover 23 is engaged with the base 21.

[0039] Specifically, each of the two side plates 213 of the base 21 is provided with a first locking block 2131. The first locking block 2131 is integrally formed with the side plate 213 and extends towards the side opening of the mounting cavity 210. The first locking block 2131 can be elongated and used to achieve a stable engagement with the front cover 23. When the front cover 23 is closed onto the base 21, the first locking block 2131 can be inserted into the first locking grooves 231 provided on both sides of the front cover 23 and fixed to each other by interference fit, thereby achieving quick engagement and fixation between the front cover 23 and the base 21 without the need for additional fasteners. After engagement, the front cover 23 not only covers the opening side of the mounting cavity 210 in appearance, but also forms a stable clamping structure with the base 21, which plays a role in pressing and protecting the signal transmission component 22, thereby preventing it from loosening under vibration or external force.

[0040] Please see Figures 5 to 7 In some embodiments, the side plate 213 is further provided with a second slot 2132, which is located below the first slot 2131. The front cover 23 is provided with second slots 232 on both sides that match the second slots 2132. The second slots 232 can be inserted into the second slots 2132 so that the front cover 23 is engaged with the base 21.

[0041] Specifically, the two side plates 213 of the base 21 are provided with second slots 2132, which are located below the first locking block 2131 and extend along the direction of the first locking block 2131. The two side walls of the front cover 23 are correspondingly provided with second locking blocks 232, the size and shape of which match the second slots 2132. When the front cover 23 is assembled to the base 21, the second locking blocks 232 can slide smoothly into the second slots 2132, forming a double-locking engagement with the first locking block 2131 and the first slot 231.

[0042] When the front cover 23 moves along the base 21, the second locking block 232 first enters the second locking groove 2132, thereby guiding and initially fixing the assembly direction. As the front cover 23 continues to close, the first locking block 2131 engages with the first locking groove 231, achieving a final interference fit lock. The cooperation of the upper and lower sets of locking structures makes the entire assembly structure more stable and reliable.

[0043] Please see Figure 6 and Figure 7 In some embodiments, a third slot 2133 is provided on the inner wall opposite to the seat side plate 213. The third slot 2133 is located below the second slot 2132 and is parallel to the second slot 2132. The two side walls of the front cover 23 are also provided with third blocks 233 that match the third slot 2133. The third blocks 233 can be inserted into the third slot 2133 so that the front cover 23 is engaged with the base 21.

[0044] Specifically, the third slot 2133 and the third locking block 233 are located in the area of ​​the base plate 211 near the base 21, allowing the locking force to be more evenly distributed on the contact interface between the front cover 23 and the base 21. The third locking block 233 can be designed as a tenon structure or a beveled wedge structure to form a tight fit after being inserted into the third slot 2133. Through triple locking positioning, the connection stability between the front cover 23 and the base 21 can be effectively improved.

[0045] Please see Figure 8 and Figure 9 In some embodiments, the signal transmission element 22 includes an insulating housing 221 and a plurality of electrical pins 222. The plurality of electrical pins 222 are spaced apart within the insulating housing 221; one end of each electrical pin 222 protrudes from the bottom surface of the insulating housing 221 to form an electrical contact 2223 for electrical connection with a hot shoe contact on a camera. The other end of each electrical pin 222 extends into the insulating housing 221 for electrical connection with circuitry within the accessory body 10.

[0046] Specifically, the insulating housing 221 may be made of a high-strength insulating material, such as PBT, nylon, or polycarbonate, to balance mechanical strength and electrical insulation performance. Each electrical contact 222 is made of a highly conductive metal material, such as gold-plated copper or nickel-plated brass; the electrical contact 222 may have a flat, sheet-like structure for easy arrangement and installation.

[0047] like Figure 2 As shown, one end of the electrical contact pin 222 protrudes slightly from the bottom surface of the insulating housing 221 to form an electrical contact 2223. This electrical contact 2223, in the assembled state, is located precisely at the side edge of the base 21 and is used to mate with the corresponding metal contact inside the camera's hot shoe slot, achieving signal and power conduction connection. To improve the stability of the electrical contact, the electrical contact 2223 can be configured with an elastic arc surface structure, creating an adaptive pressing effect when in contact with the hot shoe contact, thereby reducing signal jitter or poor contact. The other end of the electrical contact pin 222 extends into the internal space of the insulating housing 221 and is electrically connected to the circuit board 13 inside the accessory body 10 via a power strip cable. This allows the signal transmission component 22 to form a stable electrical signal transmission path between the camera and the accessory body 10, enabling functions such as synchronous triggering, power supply, or data communication.

[0048] Please see Figure 8 and Figure 9 In some embodiments, the insulating housing 221 includes an insulating base plate 2211 and an insulating side plate 2212. The insulating side plate 2212 is fixed at an angle to the insulating base plate 2211. The bottom surface of the insulating base plate 2211 is provided with a plurality of mutually spaced mounting grooves, and the insulating side plate 2212 is provided with a plurality of mounting holes corresponding one-to-one with the mounting grooves. The mounting holes extend along the height direction of the insulating side plate 2212 and pass through the insulating side plate 2212.

[0049] Furthermore, the electrical contact 222 includes a first contact arm 2221 and a second contact arm 2222 connected to each other. The first contact arm 2221 is disposed in a mounting groove on the insulating bottom surface; the second contact arm 2222 passes through a mounting hole in the insulating side plate 2212. The free end of the first contact arm 2221 extends from the side edge of the base 21 and protrudes from the bottom surface of the insulating bottom plate 2211 to form an electrical contact 2223; the free end of the second contact arm 2222 is electrically connected to the accessory body 10 via a ribbon cable.

[0050] Specifically, the insulating base plate 2211 and the insulating side plate 2212 are fixed at right angles, and the first contact arm 2221 and the second contact arm 2222 are also fixed at right angles to form an L-shaped structure that can match each other. The bottom surface of the insulating base plate 2211 has multiple mounting slots spaced along its width. Each mounting slot is used to accommodate the first contact arm 2221 of the electric contact 222, enabling precise positioning of the electric contact 222. Correspondingly, the insulating side plate 2212 has multiple mounting holes that correspond one-to-one with the mounting slots. Each mounting hole extends along the height direction of the insulating side plate 2212 and passes through it, allowing the second contact arm 2222 of the electric contact 222 to pass through it.

[0051] The insulating base plate 2211 and the insulating side plate 2212 together define the mounting channel for the electrical contact pins 222, so that the electrical contact pins 222 can maintain a precise arrangement spacing during the installation process and can be quickly installed to form a modular signal transmission component 22, thereby further improving the assembly efficiency of the hot shoe assembly 20.

[0052] Please see Figure 10 In some embodiments, the second contact arm 2222 is also provided with reinforcing teeth 2224. During the process of inserting the second contact arm 2222 into the mounting hole of the insulating side plate 2212, the reinforcing teeth 2224 can form a tight fit with the hole wall, thereby effectively preventing the contact from loosening or shifting due to vibration, friction or insertion and removal impact during long-term use, and ensuring the stable position of the electric contact 222.

[0053] Please see Figure 3 , Figure 5 and Figure 8 In some embodiments, the insulating housing 221 further includes a connecting portion 2213, which is disposed on the top surface of the insulating base plate 2211 and is used to fix it to the front cover 23.

[0054] Specifically, the top surface of the insulating base plate 2211 is provided with at least one connecting part 2213, which can be a stud or a fixing hole with internal threads, for example... Figure 8As shown, the connecting part adopts a stud structure, which extends vertically upward from the top surface of the insulating base plate 2211. When the front cover 23 is assembled to the base 21 and abuts against the signal transmission component 22, the screw 234 can be passed through the through hole on the front cover 23 and then threaded into the connecting part 2213 on the top surface of the insulating base plate 2211 to achieve a tight fixation between the front cover 23 and the insulating housing 221. The connection stability of the hot shoe assembly 20 can be further ensured by fixing it with the screw 234 and the stud.

[0055] Of course, in some embodiments, the connecting part 2213 may also be a metal fitting, which can be directly connected to the front shell through an interference fit to achieve the connection and fixation between the front shell and the signal transmission component 22.

[0056] Please see Figure 7 and Figure 8 In some embodiments, the seat side plate 213 extends forward and protrudes beyond the seat base plate 211 on the side away from the seat body 212. A latch 2134 is provided on the inner wall of the protruding portion of the seat side plate 213; the signal transmission component 22 has latching protrusions 2214 on both sides that cooperate with the latch 2134. When the signal transmission component 22 is housed within the mounting cavity 210, the latching protrusions 2214 are embedded within the latch 2134 to achieve limiting and fixing.

[0057] Specifically, the seat side plate 213 extends beyond the edge of the seat base plate 211 to form a protruding portion. The inner wall of this protruding portion is provided with a notch 2134 along the height direction for limiting the signal transmission component 22. The insulating base plate 2211 of the signal transmission component 22 has downwardly protruding latches 2214 on both sides, and the shape and size of the latches 2214 match the notches 2134 of the protruding portion of the seat side plate 213.

[0058] When the signal transmission component 22 is placed into the semi-closed mounting cavity 210 with the side opening formed by the base 21, the latching protrusion 2214 of the signal transmission component 22 can be inserted into the latch 2134 of the protruding part of the side plate of the base 21, thereby achieving the initial positioning of the signal transmission component 22, so as to facilitate the subsequent fixing of the front cover 23.

[0059] Please see Figure 4 and Figure 5 In some embodiments, the base 21 further includes a locking element 24 and an unlocking button 25. The locking element 24 is provided with a positioning post 241, which passes through the base body 212 and can extend from below the base plate 211 to form a reliable locking engagement with the camera hot shoe groove.

[0060] An inclined surface is provided between the unlock button 25 and the locking member 24. When the user presses the unlock button 25, the inclined surface pushes the positioning post 241 of the locking member 24 upward to retract into the body 212, thereby unlocking the mating hole of the camera's hot shoe and facilitating the disassembly of the photographic accessory connection device 100. When the unlock button 25 is released, the spring 251 between the unlock button 25 and the locking member 24 pushes the button back to its original position, and the positioning post 241 of the locking member 24 extends out of the base plate and inserts into the mating hole in the camera's hot shoe, achieving automatic reset locking. This structure is not only easy to operate but also maintains locking reliability during long-term use, preventing accidental dislodgement, and facilitates quick installation and removal of accessories.

[0061] In summary, this embodiment provides a photographic accessory connection device 100, which includes an accessory body 10 and a hot shoe assembly 20 disposed under the accessory body 10. The hot shoe assembly 20 includes a base 21, a signal transmission component 22, and a front cover 23. The base 21 has a mounting cavity 210 with a side opening. The signal transmission component 22 is disposed within the mounting cavity 210, and the electrical contacts 2223 on the bottom surface of the signal transmission component 22 extend from the side edge of the base 21. Through the semi-enclosed enclosure design of the base 21 and the detachable connection between the front cover 23 and the base 21, the signal transmission component 22 is clamped and fixed between the two, making the installation and removal of the signal transmission component 22 simpler, eliminating the need to insert conductive terminals from under the base 21 and fix it on the back with a cover plate. This significantly improves assembly efficiency and ease of maintenance, effectively balancing the structural strength and assembly convenience of the hot shoe assembly 20.
