Abstract
Description
Technical Field
[0001] This utility model relates to the field of photographic equipment technology, and in particular to a connector and connector assembly that prevents accidental disassembly. Background Technology
[0002] In the field of photographic equipment, the QD connector (Quick Detach) is widely used for connecting camera straps to cameras due to its excellent fastening and durability, especially its outstanding suitability in cold environments. In actual shooting scenarios, photographers often need to quickly connect the camera to the camera strap or perform disassembly and installation operations at any time. The existence of the QD connector greatly improves the convenience of this process and effectively meets the photographer's need for operational efficiency.
[0003] Most of the mainstream QD connectors on the market today are button-type designs, equipped with two buttons, and the two buttons have the same function. Both buttons unlock the female connector by squeezing the shaft inside the connector to move.
[0004] However, this design has a significant flaw. Since the two buttons function identically, in actual use, accidental activation of a single button due to external force, clothing scratches, or other unforeseen circumstances can trigger the axis to move, leading to mis-locking of the connector. As a delicate and valuable piece of equipment, a camera falling off the strap due to mis-locking could cause serious consequences, such as damage to the outer casing, loosening or damage to internal components. This would not only disrupt shooting schedules but also incur high repair costs for the photographer. Utility Model Content
[0005] The main purpose of this utility model is to propose a connector that prevents accidental disconnection, aiming to solve the technical problem that connectors in current photographic equipment are prone to accidental locking due to a single button press.

[0015] Optionally, the motion-limiting structure includes:
[0016] A limiting member is movably disposed on the inner shaft or the outer casing;
[0017] The first reset element acts on the limiting element;
[0018] The limiting member has a limiting position on its movement path. When the limiting member is in the limiting position, it stops the inner shaft. The limiting member can move away from the limiting position under the drive of the releasing mechanism. The first reset member is used to provide a force to the limiting member to reset it toward the limiting position.
[0019] Optionally, the side wall of the outer casing is provided with a first mounting hole communicating with the sliding cavity, and the release mechanism is mounted in the first mounting hole;
[0020] The limiting member is a stop pin, the side wall of the inner shaft is provided with a sliding hole, the stop pin is slidably engaged with the sliding hole to be movably disposed on the inner shaft, and the first reset member is a first spring, the first spring is housed in the sliding hole and acts on the stop pin;
[0021] The stop pin extends into the first mounting hole to reach the limited position by the elastic force of the first spring, or exits from the first mounting hole to leave the limited position by the expulsion mechanism.
[0022] Optionally, the side wall of the housing is provided with a second mounting hole communicating with the sliding cavity, and the main unlocking mechanism is mounted in the second mounting hole;
[0023] One end of the main unlocking mechanism extends into the sliding cavity and is constructed with a pressure-applying inclined surface. The side wall of the inner shaft is constructed with a pressure-receiving inclined surface, and the pressure-receiving inclined surface and the pressure-applying inclined surface form a contact fit.
[0024] The outer casing is provided with a second reset member, which is used to provide a force to the inner shaft to reset it.
[0025] Optionally, the inner shaft is provided with a receiving hole, and the second reset member is a second spring, one end of the second spring abutting against the cavity wall of the sliding cavity, and the other end extending into the receiving hole and abutting against the bottom wall of the receiving hole.
[0026] Optionally, the outer casing includes a first housing and a second housing, the first housing having a first cavity and the second housing having a second cavity;
[0027] The second housing is detachably connected to the first housing, and the first cavity and the second cavity are joined together to form the sliding cavity;

[0034] This utility model also proposes a connector assembly, which includes a connecting connector and an anti-accidental contact disassembly connector as described above. The connecting connector is used to connect photographic equipment, and the anti-accidental contact disassembly connector is inserted and locked to the connecting connector.
[0035] This utility model's anti-accidental locking disassembly connector utilizes an independent main unlocking mechanism and a safety lock mechanism to form a dual-button unlocking mechanism. In the normal locked state, the limiting structure is not driven by the unlocking mechanism, thus restricting the movement of the inner shaft and preventing it from moving. Even if either the main unlocking mechanism or the unlocking mechanism is accidentally activated due to external force, clothing scratches, or other unforeseen circumstances, the inner shaft cannot move, and the locking tongue structure will not loosen, effectively preventing accidental locking. Only after pressing the unlocking mechanism to drive the limiting structure and allow the inner shaft to move, and then operating the main unlocking mechanism to press the inner shaft, can the locking tongue structure be released to unlock the connector. This dual-button unlocking mechanism reduces the risk of accidental locking. Furthermore, this design does not affect the photographer's normal quick connection and disassembly operations. While ensuring ease of operation, it significantly improves the safety and stability of photographic equipment connections, reduces the risk of equipment damage and maintenance costs due to accidental locking, and provides photographers with a more reliable user experience.

[0044] This utility model embodiment provides an anti-accidental disassembly connector 100 for connecting and locking photographic equipment, wherein, referring to... Figures 1 to 3 The anti-accidental disconnect connector 100 includes:
[0045] The outer casing 110 has a sliding cavity 110Q inside. One end of the outer casing 110 along its axial direction is constructed with a plug-in part 110B for connecting with photographic equipment. A locking tongue structure 10 is provided through the side wall of the plug-in part 110B.
[0046] The inner shaft 120 is slidably disposed in the slide cavity 110Q. The inner shaft 120 can be moved to switch positions to tighten or loosen the locking tongue structure 10.
[0047] The main unlocking mechanism 130 is movably disposed on the side wall of the housing 110. The main unlocking mechanism 130 is used to press the inner shaft 120 to move and release the locking tongue structure 10.
[0048] The safety lock mechanism includes:
[0049] The unlocking mechanism 150 is movably installed through the side wall of the housing 110 and is arranged at a distance from the main unlocking mechanism 130.
[0050] Movement-limiting structure 140, the movement-limiting structure configuration is as follows:
[0051] When not driven by the release mechanism 150, the inner shaft 120 is prevented from moving;
[0052] When driven by the release mechanism 150, the inner shaft 120 is allowed to move.
[0053] In this embodiment, as Figures 1 to 3As shown, the outer casing 110 can be cylindrical in shape, and its interior has a sliding cavity 110Q with a diameter adapted to the inner shaft 120. The inner wall of the sliding cavity 110Q can be precision-processed to have low roughness, thereby reducing the friction when the inner shaft 120 slides. One end of the outer casing 110 along its axial direction has a connector 110B for inserting photographic equipment. The diameter of the connector 110B is smaller than the diameter of the outer casing 110, and it is stepped in shape to facilitate insertion into the photographic equipment's interface. The side wall of the connector 110B has mounting holes for installing the locking tongue structure 10. The outer casing 110 provides structural support and protection for the entire anti-accidental contact disassembly connector 100, the sliding cavity 110Q provides space for the sliding of the inner shaft 120, the connector 110B cooperates with the photographic equipment to achieve connection, and the locking tongue structure 10 plays a crucial role in locking.
[0054] like Figure 3 As shown, the inner shaft 120 can be roughly cylindrical in shape, with its outer diameter matching the inner diameter of the sliding cavity 110Q. It can slide flexibly within the sliding cavity 110Q without excessive wobbling. One end of the inner shaft 120 can be provided with a beveled surface for engaging with the locking tongue structure 10. This beveled surface angle can be 30°. When the inner shaft 120 moves, it engages or disengages the locking tongue structure 10 via this beveled surface. The inner shaft 120 can switch positions by moving within the sliding cavity 110Q, thereby engaging or disengaging the locking tongue structure 10. This is the core component for locking and unlocking the anti-accidental contact disassembly connector 100 with photographic equipment. The photographic equipment involved can be a camera or other photographic devices, or auxiliary equipment used to assist photographic equipment in photography; this embodiment does not impose any limitations on this.
[0055] The main unlocking mechanism 130 can be a main unlocking operation key, which can be made of engineering plastic to ensure good tactile feel and durability. The main unlocking mechanism 130 is movably installed through the side wall of the housing 110, with one end extending into the sliding cavity 110Q and forming a contact engagement with the inner shaft 120. When the main unlocking mechanism 130 is pressed, the main unlocking mechanism 130 converts the pressing pressure into a force that pushes the inner shaft 120 to move, thereby causing the inner shaft 120 to move and release the locking tongue structure 10.
[0056] The safety lock mechanism comprises a limiting structure 140 and a releasing mechanism 150, wherein:
[0057] Specifically, the function of the movement-limiting structure 140 is to form or release the restriction on the movement of the inner shaft 120, which is an important structure to ensure that the anti-accidental contact disassembly connector 100 will not be easily mis-locked. When the movement-limiting structure 140 restricts the movement of the inner shaft 120, the inner shaft 120 is in a non-movable state. For example, the main unlocking mechanism 130 pressing the inner shaft 120 will not drive the inner shaft 120 to move. When the movement-limiting structure 140 releases the restriction on the movement of the inner shaft 120, the inner shaft 120 is in a movable state. For example, the inner shaft 120 can move under the pressing action of the main unlocking mechanism 130.
[0058] The limiting structure 140 can be configured in various ways. For example, the limiting structure 140 includes a limiting post and a limiting spring. The limiting post is slidably disposed in a limiting hole on the side wall of the outer casing 110, and the limiting hole communicates with the sliding cavity 110Q. The limiting spring is disposed in the limiting hole, with one end abutting against the limiting post and the other end abutting against the bottom of the limiting hole. Under normal conditions, the limiting spring pushes the limiting post into the limiting groove of the inner shaft 120, thereby limiting the movement of the inner shaft 120.
[0059] The release mechanism 150 can be a release operation key, acting on the limiting structure 140 to drive the limiting structure 140, thereby releasing the limiting structure 140 from restricting the movement of the inner shaft 120. When the limiting structure 140 is not driven by the release mechanism 150, it prevents the inner shaft 120 from moving; while when driven by the release mechanism 150, it allows the inner shaft 120 to move. Referring to the above example, the release mechanism 150 can be positioned opposite the limiting post, and the inner side of the main unlocking mechanism 130 can be configured with a push rod portion. A pushing protrusion protrudes from the side of the limiting post, and the push rod portion is positioned opposite the pushing protrusion from the side of the inner shaft 120. When the user presses the release mechanism 150, its push rod contacts and presses the protrusion to push the limit post to move, causing the limit post to retract into the limit hole and then exit from the limit groove of the inner shaft 120, thus releasing the restriction on the movement of the inner shaft 120. At the same time, the limit spring accumulates elastic potential energy. When the user releases the main unlocking mechanism 130, if the limit post is aligned with the limit groove of the inner shaft 120, the limit post will be inserted into the limit groove under the elastic force of the limit spring, thus restricting the movement of the inner shaft 120.
[0060] The above example is one of many possible implementation schemes. Other schemes are also possible, which will be further explained in subsequent embodiments.
[0061] In this embodiment, the anti-accidental unlocking connector 100 forms a dual-key unlocking mechanism by setting an independent main unlocking mechanism 130 and configuring a safety lock mechanism. In the normal locked state, the limiting structure 140 is not driven by the unlocking mechanism 150, thus restricting the movement of the inner shaft 120, preventing the inner shaft 120 from moving. Even if either the main unlocking mechanism 130 or the unlocking mechanism 150 is accidentally activated due to external force, clothing scratches, or other unexpected situations, the inner shaft 120 cannot move, and the locking tongue structure 10 will not loosen, effectively preventing accidental locking of the connector. Only after operating the unlocking mechanism 150 to drive the limiting structure 140 and allow the inner shaft 120 to move, and then pressing the main unlocking mechanism 130 to squeeze the inner shaft 120 to move, can the locking tongue structure 10 be released to achieve unlocking. The dual-key unlocking mechanism reduces the risk of accidental locking.
[0062] In addition, this design does not affect the photographer's normal quick connection and disconnection operations. While ensuring ease of operation, it greatly improves the safety and stability of the connection of photographic equipment, reduces the risk of equipment damage and maintenance costs caused by mis-locking, and provides photographers with a more reliable user experience.
[0063] In some embodiments, refer to Figure 3 The motion-limiting structure 140 includes:
[0064] The limiting member 141 is movably disposed on the inner shaft 120 or the outer casing 110;
[0065] The first reset element 142 acts on the limiting element 141;
[0066] The limiting member 141 has a limiting position on its movement path. When the limiting member 141 is in the limiting position, it stops the inner shaft 120. The limiting member 141 can move away from the limiting position under the drive of the release mechanism 150. The first reset member 142 is used to provide a force to the limiting member 141 to reset it toward the limiting position.
[0067] In this embodiment, the limiting structure 140 adopts a design of limiting member 141 and first reset member 142 to improve the reliability and stability of the limiting movement. The limiting member 141 is movably disposed on the inner shaft 120 or the outer shell 110. When the limiting member 141 is disposed on the inner shaft 120, it can slide and connect with the inner shaft 120 through a specific sliding hole, ensuring that the limiting member 141 can move in a preset direction. If disposed on the outer shell 110, it is movably installed through a guide hole. The inner wall of the guide hole is smooth, reducing the resistance to the movement of the limiting member 141. The limiting member 141 has a limiting position on its movement path. When the limiting member 141 is in the limiting position, it can stop the inner shaft 120, effectively restricting the movement of the inner shaft 120, thereby preventing the inner shaft 120 from displacing and causing the connector to mis-lock when the main unlocking mechanism 130 is accidentally activated.
[0068] The first reset member 142 acts on the limiting member 141, and its specific form can be an elastic element such as a spring or elastic rubber. The first reset member 142 is used to provide a force to the limiting member 141 to reset it toward the limiting position, ensuring that the limiting member 141 is always in the limiting position when it is not subjected to external force, and maintaining the stopping state of the inner shaft 120.
[0069] In conjunction with the movement limiting structure 140, the release mechanism 150 of the anti-accidental contact disassembly connector 100 is movably disposed through the side wall of the housing 110, and one end of the release mechanism 150 contacts the movement limiting member 141. When the release mechanism 150 is pressed, it can drive the movement limiting member 141 to move away from the movement limiting position, thereby releasing the restriction on the movement of the inner shaft 120. At this time, operating the main unlocking mechanism 130 can unlock and separate the anti-accidental contact disassembly connector 100 from the photographic equipment.
[0070] The anti-accidental unlocking connector 100, employing the limiting structure 140, significantly enhances its anti-accidental unlocking capability through the ingenious cooperation of the limiting member 141, the first reset member 142, and the unlocking mechanism 150. The limiting member 141, when in the limited position, stops the inner shaft 120, acting as a safety barrier for the connector and greatly reducing the risk of accidental unlocking due to unexpected force on the main unlocking mechanism 130. Furthermore, the first reset member 142 allows the limiting member 141 to automatically reset, reducing user steps and improving ease and smoothness of use, providing photographers with a safer and more efficient user experience in various shooting scenarios.
[0071] In some embodiments, refer to Figure 3 and Figure 4 The outer casing 110 has a first mounting hole 1101 on its side wall that communicates with the sliding cavity 110Q, and the release mechanism 150 is installed in the first mounting hole 1101;
[0072] The limiting member 141 is a stop pin, and the side wall of the inner shaft 120 is provided with a sliding hole 1201. The stop pin is slidably engaged with the sliding hole 1201 to be movably disposed in the inner shaft 120. The first reset member 142 is a first spring, which is housed in the sliding hole 1201 and acts on the stop pin.
[0073] The stop pin extends into the first mounting hole 1101 to reach the limited position by the elastic force of the first spring, or exits from the first mounting hole 1101 to leave the limited position by the expulsion of the release mechanism 150.
[0074] The limiting structure 140 in this embodiment has a more specific and optimized design. The side wall of the outer shell 110 has a first mounting hole 1101 communicating with the sliding cavity 110Q. This first mounting hole 1101 provides a mounting position for the release mechanism 150. The release mechanism 150 is precisely installed in the first mounting hole 1101 with an interference fit, ensuring that it will not easily loosen during use while allowing for flexible movement. The limiting member 141 is a stop pin. The side wall of the inner shaft 120 has a sliding hole 1201. The stop pin and the sliding hole 1201 are fitted with a clearance fit, ensuring that the stop pin can slide smoothly in the sliding hole 1201 of the inner shaft 120, thereby enabling the stop pin to be movably mounted on the inner shaft 120. The first reset member 142 is a first spring. The first spring is housed in the sliding hole 1201, with one end tightly abutting the bottom of the sliding hole 1201 and the other end contacting the stop pin. It generates elastic force through its own elastic deformation, continuously acting on the stop pin.
[0075] Under normal conditions, the stop pin extends outward along the axis of the sliding hole 1201 under the elastic force of the first spring until it enters the first mounting hole 1101 on the side wall of the housing 110, at which point the stop pin reaches the limited movement position. When the stop pin is in the limited movement position, the part of it extending into the first mounting hole 1101 will cooperate with the hole wall of the first mounting hole 1101 to form a mechanical stop on the movement of the inner shaft 120, effectively restricting the sliding of the inner shaft 120 in the sliding cavity 110Q. Even if the main unlocking mechanism 130 is accidentally touched by an external force, the inner shaft 120 cannot move, thereby preventing the locking tongue structure 10 from loosening and avoiding mis-locking of the joint. When unlocking is required, press the release mechanism 150. The end of the release mechanism 150 contacts the stop pin and applies pressure. Under the action of this pressure, the stop pin overcomes the elastic force of the first spring and slides inward along the sliding hole 1201, exiting from the first mounting hole 1101, thereby leaving the limited position and releasing the restriction on the movement of the inner shaft 120. At this time, operate the main unlocking mechanism 130 to smoothly unlock and separate the anti-accidental contact disassembly connector 100 from the photographic equipment.
[0076] In this embodiment, the clearance fit between the stop pin and the sliding hole 1201, the interference fit between the release mechanism 150 and the first mounting hole 1101, and the reasonable selection and installation method of the first spring ensure that the connection between the components of the limiting structure 140 is stable and can maintain good working performance during long-term use. The minimal wear between components reduces the likelihood of loosening or jamming, extending the overall service life of the anti-accidental contact disassembly connector 100, reducing the frequency of equipment maintenance and replacement, and providing users with a more reliable and durable user experience. It can function stably in various photography scenarios, ensuring the smooth progress of photography work.
[0077] In some embodiments, refer to Figure 3 and Figure 4The side wall of the outer casing 110 is provided with a second mounting hole 1102 that communicates with the sliding cavity 110Q, and the main unlocking mechanism 130 is installed in the second mounting hole 1102;
[0078] One end of the main unlocking mechanism 130 extends into the sliding cavity 110Q and is constructed with a pressure-applying inclined surface. The side wall of the inner shaft 120 is constructed with a pressure-receiving inclined surface, and the pressure-receiving inclined surface and the pressure-applying inclined surface form a contact fit.
[0079] The outer casing 110 is provided with a second reset member 160, which is used to provide a force to the inner shaft 120 to reset it.
[0080] In this embodiment, the main unlocking mechanism 130 and its related structures have an optimized design. The side wall of the outer shell 110 is provided with a second mounting hole 1102 that communicates with the sliding cavity 110Q. The main unlocking mechanism 130 is installed in the second mounting hole 1102 through a precise assembly process, ensuring that the main unlocking mechanism 130 can move flexibly in the hole without shaking or loosening.
[0081] One end of the main unlocking mechanism 130 extends into the sliding cavity 110Q. This end is constructed with a pressure-applying inclined surface, the angle of which is carefully designed to ensure efficient force transmission during operation. The sidewall of the inner shaft 120 is correspondingly constructed with a pressure-receiving inclined surface, which forms a tight contact fit with the pressure-applying inclined surface. When the main unlocking mechanism 130 is pressed, the pressure-applying and pressure-receiving inclined surfaces interact, converting the pressing force of the main unlocking mechanism 130 into a force that pushes the inner shaft 120 to move.
[0082] In addition, a second reset member 160 is provided on the outer casing 110. The second reset member 160 can be an elastic element such as a spring or an elastic rubber sheet. One end of the second reset member 160 is fixed to the outer casing 110, and the other end is connected to or in contact with the inner shaft 120 to provide a force to reset the inner shaft 120. After the unlocking operation is completed, the second reset member 160 can automatically restore the inner shaft 120 to its initial position. Through this structural design, a stable and efficient transmission mechanism is formed between the main unlocking mechanism 130 and the inner shaft 120. Together with the movement limiting structure 140, the release limiting mechanism 150, and the locking tongue structure 10, they constitute a complete connection and unlocking system for the anti-accidental contact disassembly connector 100.
[0083] In this embodiment, the pressure-applying inclined surface of the main unlocking mechanism 130 cooperates with the pressure-receiving inclined surface of the inner shaft 120, which can efficiently convert the user's pressing force into the moving force of the inner shaft 120, making the unlocking operation easier and less strenuous. Simply pressing the main unlocking mechanism 130 can move the inner shaft 120 and unlock the locking tongue structure 10. The operation process is simple and clear, conforms to ergonomic design, and can effectively improve the photographer's operating experience, meeting their needs for quick connection and disconnection of equipment.
[0084] In some embodiments, refer to Figure 3 and Figure 4 The inner shaft 120 is provided with a receiving hole 1202. The second reset member 160 is a second spring. One end of the second spring abuts against the cavity wall of the sliding cavity 110Q, and the other end extends into the receiving hole 1202 and abuts against the bottom wall of the receiving hole 1202.
[0085] In this embodiment, the shape and size of the receiving hole 1202 can be precisely designed according to the specifications of the second reset member 160, providing a stable installation space for the second reset member 160. The second reset member 160 adopts a second spring, which is housed in the receiving hole 1202. One end of the spring tightly abuts against the cavity wall of the sliding cavity 110Q, and the other end contacts the bottom wall of the receiving hole 1202 of the inner shaft 120. It generates elastic force through its own elastic deformation, which continuously acts on the inner shaft 120, providing an elastic force for the inner shaft 120 to reset.
[0086] The receiving hole 1202 inside the outer casing 110 provides precise installation positioning for the second spring, enabling it to maintain a stable force direction and compression state during operation. This prevents the spring from shifting or twisting during use, effectively improving the stability of the entire reset structure. Simultaneously, the tight fit between the second spring and the inner shaft 120, combined with the inclined transmission structure of the main unlocking mechanism 130 and the inner shaft 120, forms a stable mechanical system. The components cooperate and constrain each other, reducing shaking and loosening between parts, further enhancing the overall reliability of the anti-accidental contact disassembly connector 100 structure, and maintaining good working performance in various complex operating environments.
[0087] In some embodiments, refer to Figure 3 and Figure 4 The outer shell 110 includes a first shell 111 and a second shell 112. The first shell 111 has a first cavity and the second shell 112 has a second cavity.
[0088] The second housing 112 is detachably connected to the first housing 111, and the first cavity and the second cavity are joined together to form a sliding cavity 110Q;
[0089] The main unlocking mechanism 130 and the unlocking mechanism 150 are disposed in the first housing 111, and the insertion part 110B is formed in the second housing 112.
[0090] In this embodiment, the outer shell 110 adopts a split shell design, consisting of a first shell 111 and a second shell 112. The first shell 111 has a first cavity, and the second shell 112 has a second cavity. The two are assembled through a specific detachable connection method. Specifically, the connection points of the first shell 111 and the second shell 112 can be provided with matching snap-fit structures or threaded structures to ensure a stable connection and easy disassembly. When the second shell 112 is connected to the first shell 111, the first cavity and the second cavity are precisely aligned and joined together to form a sliding cavity 110Q inside the anti-accidental contact disassembly connector 100, which is used to accommodate the inner shaft 120 and allows the inner shaft 120 to slide.
[0091] The main unlocking mechanism 130 and the unlocking mechanism 150 are disposed in the first housing 111. The first housing 111 has mounting holes at corresponding positions that communicate with the sliding cavity 110Q for mounting the main unlocking mechanism 130 and the unlocking mechanism 150, so that the button can move flexibly and cooperate effectively with the inner shaft 120. The insertion part 110B is formed in the second housing 112, and its side wall has mounting holes for mounting the locking tongue structure 10.
[0092] The modular housing design 110 allows the first housing 111 and the second housing 112 to be manufactured separately, simplifying the production process and reducing production difficulty and cost. Furthermore, different housings can utilize different processing methods and materials according to functional requirements. For example, the first housing 111 can be made of a material that facilitates button installation, while the second housing 112 can be made of a material with higher strength and better wear resistance for the connector 110B, improving production flexibility and efficiency. Simultaneously, the modular design facilitates assembly, allowing for rapid assembly of components through automated equipment or manual labor, further enhancing production efficiency.
[0093] In some embodiments, refer to Figure 3 and Figure 4 At least one of the unlocking mechanism 150 and the main unlocking mechanism 130 is configured with a limiting slot 20;
[0094] One end of the second housing 112 is inserted into the first housing 111 and is configured with a limiting part 1121. The limiting part 1121 extends into the limiting groove 20. The two end walls of the limiting groove 20 are used to form a limiting engagement with the limiting part 1121 to limit the extreme position of the mechanism movement.
[0095] Based on the split-type housing 110 structure, this embodiment optimizes the limiting structure of the unlocking mechanism 150 and the main unlocking mechanism 130. At least one of the unlocking mechanism 150 and the main unlocking mechanism 130 is constructed with a limiting groove 20. This limiting groove 20 is arranged along the movement direction of the button, and its shape and size are precisely designed to meet the limiting requirements. One end of the second housing 112 is inserted into the first housing 111, and the inserted end is constructed with a limiting part 1121. The shape of the limiting part 1121 is adapted to the limiting groove 20 and can extend into the limiting groove 20. After the second housing 112 and the first housing 111 are assembled, the limiting part 1121 extends into the limiting groove 20, and the two end walls of the limiting groove 20 form a limiting fit with the limiting part 1121. This limiting relationship effectively restricts the extreme positions of the mechanism's movement, ensuring that the unlocking mechanism 150 and / or the main unlocking mechanism 130 can only move within the specified travel range during operation, avoiding damage to the mechanism or internal structure due to excessive pressing, while ensuring that the mechanism can accurately trigger the corresponding function.
[0096] In this embodiment, the limiting groove 20 and the limiting part 1121 form a limiting fit, which can accurately limit the movement stroke of the unlocking mechanism 150 and / or the main unlocking mechanism 130, ensuring that the corresponding function is accurately triggered every time the mechanism is operated. For example, during the unlocking process, the unlocking mechanism 150 can accurately push the stop pin out, and the main unlocking mechanism 130 can accurately push the inner shaft 120 to move, avoiding unlocking failure or damage to the internal structure due to insufficient or excessive movement of the mechanism, thus improving the reliability and stability of the operation and providing a guarantee for photographers to quickly and accurately connect and disconnect equipment during shooting.
[0097] In some embodiments, refer to Figure 1 The unlocking mechanism 150 and the main unlocking mechanism 130 are positioned opposite each other on the periphery of the housing 110. This relative arrangement creates a symmetrical spatial distribution between the two mechanisms. When the user unlocks, they can naturally control both mechanisms with their thumb and forefinger respectively, resulting in a smooth, comfortable, and more balanced operation. This effectively improves operational efficiency and reduces accidental operation caused by inconvenience. Furthermore, the relative arrangement of the two mechanisms provides a degree of physical isolation, reducing the risk of accidental activation of one mechanism triggering the other. In complex usage environments, such as when a photographer is shooting outdoors and their clothing is scratched or the equipment is bumped, the relative arrangement of the mechanisms makes them less susceptible to simultaneous impact, further enhancing the ability to prevent accidental unlocking.
[0098] In some embodiments, refer to Figures 1 to 4 The locking tongue structure 10 includes a plurality of spherical locking tongues 11, which are spaced apart circumferentially along the insertion portion 110B.
[0099] One end of the inner shaft 120 is constructed with a pressing frustum 120T, and the side of the pressing frustum 120T forms a contact engagement with multiple spherical locking tongues 1111.
[0100] In this embodiment, the latch structure 10 employs a unique design to achieve a reliable connection with photographic equipment. The latch structure 10 includes multiple spherical latches 11, which are evenly spaced along the circumference of the insertion portion 110B. Each spherical latch 11 is installed in a corresponding mounting hole on the side wall of the insertion portion 110B and can rotate freely within the mounting hole. This design gives the spherical latches 11 good adaptability when used with photographic equipment.
[0101] The side of the extrusion frustum 120T is conical in shape and is precisely sized and angled to form a precise contact fit with multiple spherical latches 11. When the inner shaft 120 moves within the slide cavity 110Q, the side of the extrusion frustum 120T can synchronously increase or decrease the force on each spherical latch 11, thereby tightening or loosening each spherical latch 11.
[0102] In practical applications, when the anti-accidental contact disassembly connector 100 is connected to photographic equipment, the insertion portion 110B of the anti-accidental contact disassembly connector 100 is inserted into the connector of the photographic equipment. During insertion, the ball-shaped locking tongue 11 first contacts the inner wall of the connector of the photographic equipment. Since the ball-shaped locking tongue 11 can rotate freely, the friction between it and the internal structure of the photographic equipment is small, allowing it to be smoothly pressed back into the insertion portion 110B. When the insertion portion 110B is fully inserted into the connector of the photographic equipment and reaches the predetermined position, under the pressing action of the side of the pressing frustum 120T, part of the ball protrudes from the side wall of the insertion portion 110B and precisely engages in the corresponding slot of the photographic equipment, thus locking the anti-accidental contact disassembly connector 100 to the photographic equipment. At this time, the side of the pressing frustum 120T remains in contact with the ball-shaped locking tongue 11. Under the action of the limiting structure 140, the inner shaft 120 cannot move, ensuring that the ball-shaped locking tongue 11 will not retract, further securing the connection.
[0103] Under normal use, the limiting structure 140 restricts the movement of the inner shaft 120. Even if the main unlocking mechanism 130 is accidentally touched, the inner shaft 120 cannot move, and the pressing frustum 120T maintains a stable contact with the ball-shaped locking tongue 11. The ball-shaped locking tongue 11 is firmly locked in the slot of the photographic equipment, ensuring the reliability of the connection. When unlocking is required, first press the unlocking mechanism 150 to release the limiting structure 140 from restricting the movement of the inner shaft 120. Then press the main unlocking mechanism 130, which presses the inner shaft 120 to move within the sliding cavity 110Q. As the inner shaft 120 moves, the side of the pressing frustum 120T gradually loosens each ball-shaped locking tongue 11, allowing each ball-shaped locking tongue 11 to move freely. At this time, the anti-accidental contact disassembly connector 100 can be pulled out from the connector of the photographic equipment. During this pulling process, the ball-shaped locking tongue 11 can retract into the mounting hole, disengaging from the slot of the photographic equipment, completing the disassembly operation.
[0104] This embodiment of the invention also proposes a connector assembly, which includes a connecting connector and an anti-accidental contact detachment connector 100 as described in the foregoing embodiments. The connecting connector is used to connect photographic equipment, and the anti-accidental contact detachment connector 100 is inserted and locked to the connecting connector. The specific structure of the anti-accidental contact detachment connector 100 is as described in the foregoing embodiments. Since this connector assembly adopts all the technical solutions of all the foregoing embodiments, it has at least all the technical effects brought about by the technical solutions of the foregoing embodiments, and will not be described in detail here. The connector assembly involved in this embodiment is applied to the connection between components in photographic equipment. For example, a photographic strap can be detachably connected to a camera using this connector assembly. Specifically, the connecting connector is connected to the camera, and the anti-accidental contact detachment connector 100 is connected to the photographic strap. By inserting and locking the anti-accidental contact detachment connector 100 to the connecting connector, the camera and the photographic strap can be quickly connected. Furthermore, in this connector assembly, the connecting connector can be considered a female connector, and the anti-accidental contact detachment connector can be considered a male connector.
