A connector locking mechanism

Abstract

This invention relates to the field of connector technology, specifically to a connector locking mechanism. When connecting a plug connector and a socket connector, firstly, the retaining pin on the socket connector's connecting sleeve is aligned with the axial slot on the connector head, allowing the retaining pin to be pushed into the axial slot. Then, the connector head can be rotated, allowing the retaining pin to move along a radial groove, simultaneously bringing the first connecting tube closer to the second connecting tube. When the connector head rotates to its limit position, the end limiting groove aligns with the limiting block on the sliding sleeve, allowing the limiting block to enter the end limiting groove under the action of a limiting spring, thereby locking the connector head and preventing radial rotation, making the connection more reliable and stable. During disassembly, pulling the rotating sleeve causes the sliding sleeve to slide away from the connector head, allowing the limiting block to slide out of the end limiting groove. Then, the connector head can be rotated in the opposite direction to release the connection, resulting in a more stable and tighter connection.

Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a connector locking mechanism. Background Technology

[0002] A liquid connector is a device used to connect pipes carrying high-pressure production fluids, allowing relative movement between two components supporting the corresponding connection ends of the pipe. Liquid connectors with a self-locking mechanism are mainly used externally in chassis and cabinets to achieve quick connections between equipment and piping. Blind-mating liquid connectors without a self-locking mechanism are mainly used internally in various liquid-cooled chassis and equipment.

[0003] There is a type of compression-fit connector that connects the connector head and the connecting sleeve by applying relative pressure and then using ball bearings for limiting. This connection method uses a spring to apply clamping force to maintain a seal, but it is prone to leakage in some working environments with high liquid impact. Summary of the Invention

[0004] The purpose of this invention is to provide a connector locking mechanism that makes the connection more stable and tighter.

[0005] To achieve the above objectives, the present invention provides a connector locking mechanism, including a plug connector and a socket connector. The plug connector includes a first connecting tube body and a connector head. The connector head has an axial slot, a radial oblique slot, and an end limiting slot. The radial oblique slot communicates with the axial slot. The connector head is fixedly connected to the first connecting tube body and is located outside the connector head. The socket connector includes a connecting sleeve, a sliding sleeve, a limiting spring, a second connecting tube body, and a rotating sleeve. The connecting sleeve has a locking pin. The sliding sleeve is slidably connected to the connecting sleeve and is located inside the connecting sleeve. The second connecting tube body passes through the sliding sleeve and is fixedly connected to the connecting sleeve. The sliding sleeve has a limiting block that passes through the connection portion between the second connecting tube body and the connecting sleeve and enters the end limiting slot. The limiting spring is disposed between the sliding sleeve and the connecting sleeve. The rotating sleeve is rotatably disposed on the sliding sleeve and is detachably connected to the connecting sleeve.

[0006] The plug connector also includes a torsion spring, which is disposed on one side of the radial groove.

[0007] The plug connector further includes a first sealing ring, and the socket connector further includes a second sealing ring. The first sealing ring is fixed in the first connecting tube body, and the second sealing ring is fixed in the second connecting tube body. During connection, the first sealing ring contacts the second sealing ring.

[0008] The connecting sleeve has anti-slip grooves, which are disposed on the surface of the connecting sleeve.

[0009] The connecting sleeve further includes a limiting boss, which is disposed on the side of the connecting sleeve near the connector head to limit the connector head.

[0010] The rotating sleeve has a first limiting rod, and the connecting sleeve has an L-shaped groove that matches the first limiting rod, and the first limiting rod can slide within the L-shaped groove.

[0011] The rotating sleeve also includes a handle, which is fixedly connected to the rotating sleeve and located on one side of the rotating sleeve.

[0012] The socket connector also includes a clamp, which is disposed on one side of the rotating sleeve.

[0013] This invention provides a connector locking mechanism. When connecting a plug connector and a socket connector, the locking pin on the connecting sleeve of the socket connector is first aligned with the axial slot on the connector head, allowing the locking pin to be pushed into the axial slot. Then, the connector head can be rotated, allowing the locking pin to move along the radial groove, simultaneously bringing the first connecting tube closer to the second connecting tube. When the connector head rotates to its limit position, the end limiting groove aligns with the limiting block on the sliding sleeve, allowing the limiting block to enter the end limiting groove under the action of the limiting spring, thereby locking the connector head and preventing radial rotation, making the connection more reliable and stable. For disassembly, the rotating sleeve can be rotated to release the connection between the rotating sleeve and the connecting sleeve. Then, pulling the rotating sleeve causes the sliding sleeve to slide away from the connector head, allowing the limiting block to slide out of the end limiting groove. Finally, the connector head can be rotated in the opposite direction to release the connection. This connector locking mechanism provides a more stable and tighter connection.

[0025] First Embodiment

[0026] Please see Figures 1-3 , Figure 1 This is a connection structure diagram of a connector locking mechanism according to the first embodiment of the present invention. Figure 2 This is a disconnection structure diagram of a connector locking mechanism according to the first embodiment of the present invention. Figure 3 This is a cross-sectional structural diagram of a connector locking mechanism according to a first embodiment of the present invention. The present invention provides a connector locking mechanism including a plug connector 101 and a socket connector 102. The plug connector 101 includes a first connecting tube body 10 and a connector head 104. The connector head 104 has an axial slot 105, a radial oblique slot 106, and an end limiting slot 107. The radial oblique slot 106 communicates with the axial slot 105. The connector head 104 is fixedly connected to the first connecting tube body 10 and is located outside the connector head 104. The socket connector 102 includes a connecting sleeve 108, a sliding sleeve 109, a limiting spring 110, a second connecting tube body 111, and a rotating sleeve 112. The connecting sleeve 108 has... There is a locking post 113. The sliding sleeve 109 is slidably connected to the connecting sleeve 108 and is located inside the connecting sleeve 108. The second connecting tube 111 passes through the sliding sleeve 109 and is fixedly connected to the connecting sleeve 108. The sliding sleeve 109 has a limiting block 114. The limiting block 114 passes through the connection part of the second connecting tube 111 and the connecting sleeve 108 and enters the end limiting groove 107. The limiting spring 110 is disposed between the sliding sleeve 109 and the connecting sleeve 108. The rotating sleeve 112 is rotatably disposed on the sliding sleeve 109 and is detachably connected to the connecting sleeve 108.

[0027] In this embodiment, when connecting the plug connector 101 and the socket connector 102, the locking pin 113 on the connecting sleeve 108 of the socket connector 102 is first aligned with the axial slot 105 on the connector head 104, so that the locking pin 113 can be pushed into the axial slot 105. Then, the connector head 104 can be rotated so that the locking pin 113 can move along the radial groove 106, and at the same time, the first connecting tube 10 can move closer to the second connecting tube 111. When the connector head 104 is rotated to the limit position, the end limiting groove 107 is aligned with the limiting block 114 on the sliding sleeve 109, so that the limiting block 114 can enter the end limiting groove 107 under the action of the limiting spring 110, thereby locking the connector head 104 and preventing the connector head 104 from rotating radially, making the connection more reliable and stable. Then, during disassembly, the rotating sleeve 112 can be rotated to disconnect the rotating sleeve 112 and the connecting sleeve 108. Then, the rotating sleeve 112 is pulled to drive the sliding sleeve 109 to slide away from the connector head 104, so that the limiting block 114 can slide out from the end limiting groove 107. Then, the connector head 104 can be rotated in the opposite direction to disconnect the connection, so that the connector locking mechanism provided by the present invention can make the connection more stable and tighter.

[0028] Second Embodiment

[0029] Please see Figures 4-7 , Figure 4 This is a structural diagram of the plug connector according to the second embodiment of the present invention. Figure 5 This is a structural diagram of the socket connector according to the second embodiment of the present invention. Figure 6 This is a disconnection structure diagram of a connector locking mechanism according to a second embodiment of the present invention. Figure 7 This is a cross-sectional view of a connector locking mechanism according to a second embodiment of the present invention. Based on the first embodiment, the present invention also provides a connector locking mechanism, wherein the plug connector 101 further includes a first sealing ring 202, and the socket connector 102 further includes a second sealing ring 203. The first sealing ring 202 is fixed in the first connecting tube 10, and the second sealing ring 203 is fixed in the second connecting tube 111. During connection, the first sealing ring 202 contacts the second sealing ring 203. The contact between the first sealing ring 202 and the second sealing ring 203 increases the sealing performance to prevent liquid leakage during operation.

[0030] The connecting sleeve 108 has an anti-slip groove 204, which is disposed on the surface of the connecting sleeve. The anti-slip groove 204 can increase the friction between the user's hand and the connecting sleeve 108, making the use more stable.

[0031] The connecting sleeve 108 also includes a limiting boss 205, which is disposed on the side of the connecting sleeve 108 near the connector 104 to limit the connector 104. The limiting boss 205 can restrict the movement of the connector 104 to better control the connection force.

[0032] The rotating sleeve 112 has a first limiting rod 206, and the connecting sleeve 108 has an LL-shaped groove 207 that matches the first limiting rod 206. The first limiting rod 206 can slide within the LL-shaped groove 207. The LL-shaped groove 207 can engage the first limiting rod 206, preventing the rotating sleeve 112 from sliding axially. When it is necessary to disconnect, the rotating sleeve 112 can be rotated so that the first limiting rod 206 can slide out of the LL-shaped groove 207, and then the rotating sleeve 112 can be moved, making it more convenient to use.

[0033] The rotating sleeve 112 also includes a handle 208, which is fixedly connected to the rotating sleeve 112 and located on one side of the rotating sleeve 112. The handle 208 allows the rotating sleeve 112 to be easily rotated, making it more convenient to use.

[0034] The socket connector 102 also includes a clamp 209, which is disposed on one side of the rotating sleeve 112. The clamp 209 can limit the position of the rotating sleeve 112, making it easy to install the rotating sleeve 112.

[0035] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
