Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a pull cord connector plug-in structure. Background Technology

[0002] Currently, there are two main structural forms of plug-in connectors in existing technology: one is to add a nested outer shell to the outer shell and use this structure to achieve plug-in separation through elastic or conditional limiting; the other is to place the conditional limiting plug-in component in the middle of the connector for plug-in separation.

[0003] For the first structural form, existing technologies are further divided into three types: slotted multi-threaded locking structure, steel ball locking structure, and a combination structure of rotary docking and steel ball locking. Except for the slotted multi-threaded locking structure, the product lifespan is around 100 cycles, while the other two can reach 500 cycles. The overall structure of these three technologies is relatively thick and complex, which is not conducive to the trend of miniaturization of connector products.

[0004] For the second structural form, the existing plug-in method is relatively ideal. By placing the plug-in component in the central part, the protruding ball is used to lock the groove of the connector to achieve self-locking. However, the ball will wear out frequently during use, and the structure is relatively complex with many parts, which makes it prone to failure and large fitting errors, resulting in the connector still being able to move a large displacement back and forth when locked. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the problem that small pull rope connector plug-in structures in the prior art are prone to wear and have a short lifespan when repeatedly unlocked and unlocked, and to provide a pull rope connector plug-in structure.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A pull cord connector plug-in structure includes a socket connector and a plug connector;

[0008] The socket connector includes a socket connector body and a plugging / unplugging component; the plugging / unplugging component includes an elastic component, a self-locking component, and a pulling device, wherein the elastic component is connected to the self-locking component; the pulling device is used to drive the elastic component; the socket connector body is provided with a limiting structure at the left end of the self-locking component;

[0009] A plug connector, the plug connector including a resilient lock; the resilient lock having radial elasticity; when the resilient lock moves and presses against the self-locking component, the resilient lock enters the limiting structure; when the pulling device presses against the resilient component, the resilient lock returns to its original state.

[0010] In this design, when the socket connector and plug connector switch from a separated state to a connected state, the plug connector moves towards the socket connector and presses against it. The elastic lock, under the action of the self-locking component, opens and contacts the limiting structure of the socket connector, thus locking the connector. When the socket connector and plug connector switch from a compressed state to a separated state, the pulling device compresses the elastic component, and the self-locking component moves away from the elastic lock under the action of elastic force. At this point, without the support of the self-locking component, the elastic lock returns to its original shape based on radial elastic force, separating from the limiting structure, thus unlocking and separating the connector. The plug-in structure in this design uses a direct-insertion plug-in type, which is less prone to wear, greatly improves service life, and has a compact structure.

[0011] Preferably, the elastic lock is slotted, and the elastic lock includes a spring piece arranged in a circumferential direction, the spring piece having a protrusion at its top end that is adapted to the limiting structure.

[0012] In this design, the spring itself has radial elasticity. As the self-locking component gradually approaches and compresses, the spring expands outward, and the protruding structure, under the restraint of the limiting structure, achieves the locking of the connector.

[0013] Preferably, the resilient lock further includes a contact member extending axially, the contact member being located in the middle of the spring piece.

[0014] In this design, the contact component can enter the socket connector when it presses the self-locking component, forcing the self-locking component to move backward, thereby achieving rapid separation of the connector.

[0015] Preferably, the pulling device includes a pull rope and a clamping block. The clamping block is installed at the tail of the socket connector body via a connector. The self-locking component, the elastic component, and the clamping block are connected in sequence. The tail of the clamping block has a horizontal through hole. One end of the pull rope is fixed between the elastic component and the self-locking component, and the other end passes through the horizontal through hole.

[0016] In this design, a pulling device is used to pull the elastic component to move the socket connector, thereby enabling the connector to be inserted or removed. The pull cord in this design is a straight-pull type, which ensures that the connector is subjected to uniform force during insertion and removal, avoiding the problem of excessive separation force preventing unlocking.

[0017] Preferably, the self-locking component has a spherical structure or a beveled structure at one end of the elastic lock.

[0018] In this design, the spherical or beveled structure not only serves as a guide but also facilitates the straight insertion and removal of the connector.

[0019] Preferably, the end of the pull rope is round, and the diameter of the end is larger than the inner diameter of the transverse through hole.

[0020] In this design, the pull cord is positioned in the middle of the connector, resulting in a simple structure suitable for miniaturized connectors.

[0021] Preferably, the socket connector body includes a kit housing, and the kit housing is provided with the limiting structure, which is stepped.

[0022] Preferably, the inclined surface of the limiting structure and the protrusion structure is greater than 30° to prevent the connector from deforming and slipping out under force when it is locked.

[0023] Preferably, the spring is made of beryllium bronze.

[0024] Preferably, the elastic component is a spring.

[0025] The positive effects of this invention are as follows:

[0026] When the socket connector and plug connector switch from a separated state to a connected state, the plug connector moves towards the socket connector and presses, causing the elastic lock to open under the action of the self-locking component and contact the limiting structure of the socket connector, thereby locking the connector. When the socket connector and plug connector switch from a compressed state to a separated state, the pulling device squeezes the elastic component, and the self-locking component moves away from the elastic lock under the action of elastic force. At this time, without the support of the self-locking component, the elastic lock will return to its original shape based on radial elastic force and separate from the limiting structure, thereby unlocking and separating the connector. The plug-in structure in this solution adopts a direct plug-in type, which is not easy to wear, greatly improves the service life, and has a compact structure. Attached Figure Description

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0038] like Figure 1-3 As shown, the pull cord connector structure in this embodiment has a volume of approximately 1500 mm². 3 The socket connector includes a socket connector body and a plugging / unplugging component; the plugging / unplugging component includes an elastic component 13, a self-locking component 11, and a pulling device, wherein the elastic component 13 is connected to the self-locking component 11; the pulling device is used to drive the elastic component 13; the socket connector body is provided with a limiting structure at the left end of the self-locking component 11;

[0039] A plug connector, the plug connector including a resilient lock 21; the resilient lock 21 has radial elasticity; when the resilient lock 21 moves and presses against the self-locking component 11, the resilient lock 21 enters the limiting structure; when the pulling device presses against the resilient component 13, the resilient lock 21 returns to its original state.

[0040] like Figure 3 As shown, when the socket connector and plug connector change from a separated state to a connected state, the plug connector moves towards the socket connector and presses, causing the elastic lock 21 to open under the action of the self-locking component 11 and contact the limiting structure of the socket connector, thereby locking the connector. When the socket connector and plug connector change from a compressed state to a separated state, the pulling device squeezes the elastic component 13, and the self-locking component 11 moves away from the elastic lock 21 under the action of elastic force. At this time, without the support of the self-locking component 11, the elastic lock 21 will return to its original shape based on radial elastic force and separate from the limiting structure, thereby unlocking and separating the connector. The plug-in structure in this solution adopts a direct plug-in type, which is not easy to wear, has a mechanical life of more than 500 times, has a wide range of applications in the connector field, and has a compact structure.

[0041] like Figure 1 As shown, the elastic lock 21 is slotted and includes spring pieces arranged along the circumference. Each spring piece has a protrusion at its top that corresponds to the limiting structure. In this embodiment, the slotted elastic lock 21 is divided into four spring pieces, made of beryllium bronze to ensure a certain degree of elasticity.

[0042] Because the spring has radial elasticity, as the self-locking component 11 gradually approaches and squeezes, the spring expands outward, and the protruding structure, under the restraint of the limiting structure, achieves the locking of the connector.

[0043] Preferably, the resilient lock 21 further includes an axially extending contact member located in the middle of the spring tab. When the self-locking member 11 is pressed, the contact member can enter the socket connector and force the self-locking member 11 to move rearward, thereby achieving rapid separation between the connectors.

[0044] Preferably, the pulling device includes a pull rope 15 and a clamping block 14. The clamping block 14 is installed at the tail of the socket connector body via a connector. The self-locking component 11, the elastic component 13, and the clamping block 14 are connected in sequence. The tail of the clamping block 14 has a horizontal through hole. One end of the pull rope 15 is fixed between the elastic component 13 and the self-locking component 11, and the other end passes through the horizontal through hole. In this embodiment, the pulling device is modular and can be connected by threads.

[0045] The pulling device is used to pull the elastic component 13 to move the socket connector, thereby enabling the connector to be inserted or removed. The pull cord 15 in this design is a straight pull type, which ensures that the connector is subjected to uniform force during insertion and removal, avoiding the problem of excessive separation force preventing unlocking.

[0046] Preferably, the self-locking component 11 has a spherical or beveled structure at one end of the elastic lock 21. The spherical or beveled structure not only serves as a guide but also facilitates the straight insertion and removal of the connector.

[0047] Preferably, the end of the pull cord 15 is round, and the diameter of the end is larger than the inner diameter of the transverse through hole. The pull cord 15 is located in the middle of the connector, which is simple in structure and suitable for miniaturized connectors. In other fields involving linear mating, the size of each component can be increased to suit environments with greater self-locking force and more stringent mating requirements.

[0048] Preferably, the socket connector body includes a kit housing 12, and the kit housing 12 is provided with the limiting structure, which is stepped.

[0049] Preferably, the contact slope between the limiting structure and the protrusion structure is greater than 30° to prevent the connector from deforming and slipping out under force when it is locked.

[0050] Preferably, the shrapnel is made of beryllium bronze.

[0051] Preferably, the elastic component 13 is a spring.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
