Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a toggle-unlock connector. Background Art

[0002] Connectors are a component that our electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits within a circuit, so that current can flow and the circuit can achieve its intended function. Connectors are indispensable in electronic equipment, so there are various types of connectors on the market.

[0003] In actual applications, multiple connectors are usually set in adjacent positions and are close to each other. When operating a single connector (such as maintenance, replacement of parts, and other manual operations), it is easy for a part of the human body (such as a hand, elbow, or joint) to touch the locking button, thereby causing the locking button to be accidentally touched. Therefore, a secondary locking structure is needed to avoid and prevent the occurrence of this false operation.

[0004] The secondary locking structure is an auxiliary structure added to the connector structure mainly to prevent the failure of the primary locking structure or human misoperation. The operation of this auxiliary structure is independent of the primary locking or unlocking operation. Compared with the primary locking structure, when locking or unlocking, it must operate in two different directions on at least two different devices or equipment, so it is more reliable and plays a significant role in situations with high vibration levels (such as dynamic use and severe vibration in vehicles) and in preventing misoperation.

[0005] For example, a Chinese patent with publication number CN117791235A discloses a secondary locking plug and connector, in which the secondary locking structure of the plug is composed of an internal locking mechanism and an external sheath for covering the window. The sheath and the locking mechanism do not interfere with each other. The two locking structures do not interfere with each other, have high adaptability, and the sheath is easy to rotate to open and close.

[0006] However, the above-mentioned sheath is arranged outside the plug, and improper operation or accidental touch may change the position of the sheath, thereby causing the sheath to lose its secondary locking function, which not only affects the connection stability between the plug and the connector, but also may bring potential safety hazards.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices. Terms such as "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "bottom", etc. are based on the directions or positions shown in the drawings, which are only for the convenience of description and cannot be understood as limitations on the present technical solution.

[0034] It should be noted that the existing secondary locking connector uses a sheath to shield the internal locking mechanism, but the sheath is set on the outside of the plug. Improper human operation or accidental touch will change the position of the sheath, causing the sheath to lose its secondary locking function, thereby affecting the connection stability between the plug and the socket, and may even cause safety hazards.

[0035] like Figure 1-Figure 3As shown, this embodiment provides a toggle-to-unlock connector, in which a toggle key assembly 12 is disposed in a housing 15 of a plug body 10, and the toggle key assembly 12 is controlled to move between a locked position and an unlocked position by means of a slot 13 on the housing 15, so as to realize secondary locking and releasing of the toggle key assembly 12, thereby preventing the toggle key assembly 12 from losing its secondary locking function due to improper human operation or accidental touch, and achieving high connection stability between the plug and the socket.

[0036] Specifically, the toggle unlock connector includes a plug body 10 and a socket body 20. The plug body 10 is provided with an elastic buckle assembly 11, and the socket body 20 is provided with a buckle base assembly 21 at a position corresponding to the elastic buckle assembly 11. After the plug body 10 and the socket body 20 are plugged into each other, the elastic buckle assembly 11 and the buckle base assembly 21 are automatically engaged to achieve locking, and external force presses the elastic buckle assembly 11 to achieve unlocking of the elastic buckle assembly 11 and the buckle base assembly 21;

[0037] A dial key assembly 12 is provided in the shell 15 of the plug body 10. The shell 15 of the plug body 10 is provided with a slot 13 to control the movement of the dial key assembly 12 between a locked position and an unlocked position. When the dial key assembly 12 moves to the locked position, the dial key assembly 12 restricts the elastic buckle assembly 11 from moving downward to achieve secondary locking. When the dial key assembly 12 moves to the unlocked position, the restriction of the dial key assembly 12 on the elastic buckle assembly 11 is released.

[0038] Connection process: When the user needs to connect the plug body 10 with the socket body 20, they only need to plug the two together. During the plugging process, the elastic buckle assembly 11 will automatically engage with the buckle base assembly 21 to achieve initial locking. Then, the user moves the key assembly 12 to the locking position through the slot 13 on the housing 15. At this time, the key assembly 12 will limit the downward movement of the elastic buckle assembly 11, thereby achieving secondary locking.

[0039] Unlocking process: When disconnection is required, the user first moves the dial key assembly 12 to the unlocking position through the slot 13 on the housing 15 to release the restriction on the elastic buckle assembly 11. Then, a certain external force is applied to press the elastic buckle assembly 11 to deform it and separate from the buckle assembly 21 to achieve unlocking.

[0040] In one embodiment, the elastic buckle assembly 11 includes a buckle 111, a rotating shaft 112 and a torsion spring 113. One end of the buckle 111 is placed in the shell 15 of the plug body 10, and the other end of the buckle 111 extends out of the shell 15 of the plug body 10. The other end of the buckle 111 forms a curved or hook-shaped structure, so as to engage with the buckle assembly 21 on the socket. The rotating shaft 112 is arranged in the middle of the buckle 111, and the two ends of the rotating shaft 112 are installed on the plug body 10, similar to a supporting point, so that the buckle 111 rotates through the rotating shaft 112. The torsion spring 113 is wound on the rotating shaft 112, the middle part of the torsion spring 113 abuts on the buckle 111, and the two ends of the torsion spring 113 abut on the plug body 10. The torsion spring 113 provides elastic force for the buckle 111 to achieve elastic unlocking and locking between the elastic buckle assembly 11 and the buckle assembly 21.

[0041] When the buckle 111 is locked with the buckle assembly 21, the torsion spring 113 is used to provide a certain support force for the buckle 111 to prevent the buckle 111 from shaking during the buckling process with the buckle assembly, and to provide sufficient locking force for the buckle 111. When it is necessary to unlock, just press the buckle 111 lightly, and the torsion spring 113 is in a certain compression state. When the buckle 111 is separated from the buckle assembly, the torsion spring 113 is reset, and the buckle 111 is reset under the action of the torsion spring 113.

[0042] The outer surface of the plug body 10 is provided with a movable key surface 14 at a position corresponding to the buckle 111. The movable key surface 14 is movably connected to the plug body 10, and one end of the buckle 111 is installed on the movable key surface 14 through a torsion spring 113 pressure block to enable the movable key surface 14 to be linked with the buckle 111.

[0043] During the insertion process, the user only needs to align the buckle 111 of the plug with the buckle assembly 21 of the socket, and then gently push, and the buckle 111 will automatically combine with the buckle assembly 21 to form a firmly locked state. At this time, the torsion spring 113 provides a stable supporting force for the buckle 111.

[0044] When the plug needs to be unplugged, the user only needs to gently press one end of the movable key surface 14 to push the buckle 111 to rotate in the unlocking direction. As the buckle 111 rotates, the buckle 111 will be separated from the buckle platform assembly 21, and the plug is finally unplugged.

[0045] In one embodiment, the key assembly 12 includes a key body 121 and a key pressing plate 122. The bottom of the key body 121 extends downward to form a first boss 123. The key pressing plate 122 is provided with a through slot 124. The first boss 123 moves along the through slot 124. The movable key surface 14 is provided with a second boss 141. When the first boss 123 moves along the through slot 124 to the corresponding position of the second boss 141, secondary locking is achieved.

[0046] Preferably, an opening is provided on the dial key body 121, and the user uses a screwdriver to pass through the slot 13 and extend into the opening to control the dial key body 121 to move between the locked position and the unlocked position along the through slot 124 on the dial key pressure plate 122. In other optional embodiments, the dial key body 121 protrudes upward to form a limit block, and the limit block extends into the slot 13, but the height of the limit block does not exceed the surface of the shell 15 of the plug body 10. When using, the user uses other tools to push the limit block to control the dial key body 121 to move between the locked position and the unlocked position along the through slot 124 on the dial key pressure plate 122. It should be noted that the above two methods are only examples and cannot be understood as limitations of this solution. Other methods that can realize the control of the main body moving between the locked position and the unlocked position along the through slot 124 on the dial key pressure plate 122 are all within the protection scope of this solution.

[0047] Two sliding parts 125 are disposed on the dial key pressing plate 122 . The two sliding parts 125 are respectively disposed on two sides of the through slot 124 . The dial key body slides on the two sliding parts 125 to reduce the friction force of the sliding of the dial key body.

[0048] Both sides of the through slot 124 are recessed downward to form a limiting slot. The first boss 123 is provided with a limiting portion at a position corresponding to the limiting slot. The limiting slot and the limiting portion cooperate to limit the movement of the dial key body 121 .

[0049] In one embodiment, a locking mark and an unlocking mark are provided on the surface of the dial key body 121, and the position of the locking mark corresponds to the unlocking position, and the position of the unlocking mark corresponds to the locking position. When the user uses a tool to dial the dial key body 121 in the right direction, the metal dial key leaks out the locking mark (at this time, the first boss 123 on the dial key body 121 will support the second boss 141 at the tail of the movable key surface 14), the plug body 10 is in a secondary locking state, the buckle 111 cannot move downward, and the plug body 10 and the socket body 20 cannot be opened. When the user uses a tool to dial the dial key body 121 in the left direction, the dial key body 121 leaks out the unlocking mark (at this time, the first boss 123 on the dial key body 121 is separated from the second boss 141 at the tail of the movable key surface 14), and the buckle 111 is pressed, and the plug body 10 and the socket body 20 can be separated smoothly.

[0050] In one embodiment, the signal pin of the plug body is in the form of a socket, the power pin of the plug body is in the form of a pin, the signal pin of the socket body is in the form of a pin, and the power pin of the socket body is in the form of a socket. The mixed installation mode of pins and sockets can save product space and make the product smaller.

[0051] In one embodiment, the plug body 10 is provided with a plastic cap at the connection of the cable to increase the sealing performance of the plug body 10 , thereby meeting the IP20 requirement.

[0052] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0053] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
