Description
Technical Field
[0001] This utility model relates to the field of connector technology, and more specifically to a connector with locking and unlocking functions. Background Technology
[0002] A connector is a device used for electrical and / or communication connections between two components. Connectors typically have a socket and a plug. Generally speaking, the structure of connectors varies depending on the actual usage requirements, but in the existing technology, the connection and separation between the plug and socket of connectors are basically achieved by plugging and pulling.
[0003] First, in connectors with cables, this method can easily cause the plug and socket to loosen or even separate due to the cable being pulled incorrectly. Second, when it is necessary to separate the socket and plug, the plug can only be pulled out by pinching it with your fingers. When pulling it out, it is difficult to pull out because the direction of force is not in a straight line with the insertion direction between the plug and socket, and it is also easy to damage the terminals.
[0004] Therefore, in order to overcome the above problems, the applicant has made improvements to the existing technology. Utility Model Content

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0034] Connector, please refer to Figure 1-5 As shown, it includes: a plug assembly 100 and a socket assembly 200, with plug-in connection and disconnection between the plug assembly 100 and the socket assembly 200.
[0035] Specifically, the plug assembly 100 includes: a first base 110, a plug terminal 120, a retaining ring 130, an outer cover 140, and a pull ring 150;
[0036] The socket assembly 200 includes: a second base 210 and a socket terminal 220; after the plug assembly 100 and the socket assembly 200 are assembled, the plug terminal 120 and the socket terminal 220 are connected.
[0037] like Figure 4 As shown, the first base 110 is disposed on the outer cover 140. The first base 110 and the outer cover 140 can be an integral structure or a separate assembly structure.
[0038] Optionally, when the first base 110 and the outer cover 140 are assembled separately, they can be connected by a snap-fit or a threaded connection; and the outer cover 140 is designed in the shape of a handle to facilitate applying force to the plug assembly 100.
[0039] Furthermore, the fixing ring 130 is sleeved on the outside of the first base 110 and can rotate; between the inner wall of the fixing ring 130 and the outer wall of the second base 210, one is provided with a screw-lock groove and the other is provided with a screw-lock protrusion, and the plug assembly 100 and the socket assembly 200 are locked by the screw-lock groove and the screw-lock protrusion.
[0040] Furthermore, the pull ring 150 is mounted on the outer cover 140 and can swing, and the fixing ring 130 is provided with a trigger part 131. After the pull ring 150 swings, it pushes the trigger part 131 to make the fixing ring 130 rotate, thereby unlocking the plug assembly 100 and the socket assembly 200.
[0041] As can be seen from the above, after the plug assembly 100 and the socket assembly 200 are plugged in, they are locked by the engagement of the swivel groove and the swivel protrusion to prevent the plug assembly 100 and the socket assembly 200 from being accidentally separated; and when the plug assembly 100 and the socket assembly 200 are separated, they are unlocked by rotating the pull ring 150.
[0042] In one implementation, such as Figure 4 As shown, the first base 110 is provided with a first sleeve 111, and the plug terminal 120 is located inside the first sleeve 111;
[0043] Similarly, the second base 210 is provided with a second sleeve 211, and the socket terminal 220 is located inside the second sleeve 211;
[0044] The fixing ring 130 is sleeved on the outside of the first sleeve 111, and a gap 101 is formed between the inner wall of the fixing ring 130 and the outer wall of the first sleeve 111 for the second sleeve 211 to be inserted.
[0045] Furthermore, between the first sleeve 111 and the fixing ring 130, one is provided with an arc-shaped groove and the other is provided with a locking protrusion. The length of the arc-shaped groove is greater than the length of the locking protrusion, so that the fixing ring 130 is limited to the outside of the first base 110 and can rotate.
[0046] Specifically, such as Figure 4 As shown, the first sleeve 111 is provided with an arc-shaped groove 1111, which is opened along the circumference of the first sleeve 111. The inner wall of the fixing ring 130 is provided with a locking protrusion 133. After assembly, the locking protrusion 133 of the fixing ring 130 is engaged in the arc-shaped groove 1111, so that the fixing ring 130 can rotate on the first sleeve 111, but the fixing ring 130 cannot detach from the first sleeve 111 in the axial direction.
[0047] Meanwhile, the length of the arc groove 1111 limits the rotation angle of the fixed ring 130.
[0048] Furthermore, the fixing ring 130 can be rotated to a first position and a second position;
[0049] When the retaining ring 130 rotates to the first position, the plug assembly 100 and the socket assembly 200 are locked together;
[0050] When the retaining ring 130 rotates to the second position, the plug assembly 100 and the socket assembly 200 are unlocked;
[0051] Here, the rotation of the fixed ring 130 from the first position to the second position is defined as a forward rotation, and the rotation of the fixed ring 130 from the second position to the first position is defined as a reverse rotation.
[0052] Furthermore, an elastic element (not shown in the figure) is provided between the fixing ring 130 and the first base 110, which provides the elastic force for the fixing ring 130 to return from the second position to the first position;
[0053] Specifically, the elastic element can be a spring, torsion spring, sheet spring, or other similar structure.
[0054] In one embodiment, the screw-on groove 212 and the screw-on protrusion 132 are respectively provided with inclined guide surfaces; under the action of the inclined guide surfaces, the retaining ring 130 rotates during the insertion of the plug assembly 100 and the socket assembly 200;
[0055] Specifically, the throttle protrusion 132 is provided with a first inclined guide surface 1321, and the throttle groove 212 is provided with a second inclined guide surface 2121. During the insertion of the plug assembly 100 and the socket assembly 200, the second sleeve 211 is inserted into the gap 101, and the first inclined guide surface 1321 and the second inclined guide surface 2121 abut against each other, converting the linear motion into the rotational motion of the fixed ring 130.
[0056] Continue as Figure 4 As shown, the swivel groove 212 has an inlet section 201 and a limiting section 202. As the plug assembly 100 and the socket assembly 200 are deeply inserted, the retaining ring 130 rotates in the forward direction. After the plug assembly 100 and the socket assembly 200 are inserted, the swivel protrusion 132 moves to the beginning of the limiting section 202. Under the elastic force of the elastic element, the retaining ring 130 rotates in the reverse direction, so that the swivel protrusion 132 is engaged in the limiting section 202. It can be engaged in the middle of the limiting section 202 or even engaged in the end of the limiting section 202, thereby locking the socket assembly 200 and the plug assembly 100.
[0057] Therefore, as can be seen from the above, the plug assembly 100 and the socket assembly 200 can achieve self-locking after being plugged in.
[0058] In one embodiment, the swivel groove 212 is provided with an inclined guide surface 2122. When the socket assembly 200 and the plug assembly 100 are unlocked, the inclined guide surface 2122 interacts with the side surface 1322 of the swivel protrusion 132 during the rotation of the retaining ring 130 from the first position to the second position, pushing the second sleeve 211 away from the gap 101.
[0059] Specifically, such as Figure 4 As shown, the inclined guide surface 2122 and the second inclined guide surface 2121 are roughly arranged in a figure-eight shape;
[0060] When the socket assembly 200 and plug assembly 100 are in the locked state, when the retaining ring 130 rotates forward and the buckle protrusion 132 rotates to the beginning of the limiting section 202, its side 1322 abuts against the inclined guide surface 2122; when the retaining ring 130 continues to rotate forward, the side 1322 cooperates with the inclined guide surface 2122 to switch the rotational motion of the retaining ring 130 to the linear motion of the second sleeve 211, pushing the second sleeve 211 out of the gap 101, that is, pushing the plug assembly 100 and the socket assembly 200 to separate.
[0061] Therefore, by applying force to swing the pull ring 150, the fixed ring 130 is driven to rotate, and finally the plug assembly 100 and the socket assembly 200 are separated. During the separation process, the plug terminals 120 and 220 are effectively prevented from bending or being damaged.
[0062] In one embodiment, the trigger part 131 protrudes radially from the fixing ring 130, and the pull ring 150 is provided with a trigger arm 151. During the rotation of the pull ring 150, the trigger arm 151 pushes the trigger part 131 to make the fixing ring 130 rotate.
[0063] Specifically, such as Figure 4 As shown, the pull ring 150 has two swing arms and a connecting arm connecting the two swing arms, and one of the swing arms is provided with a trigger arm 151; as Figure 5 As shown, the pull ring 150 rotates counterclockwise. During the rotation, the trigger arm 151 will contact the trigger part 131, and as... Figure 5 The downward triggering part 131 is shown, which in turn causes the fixed ring 130 to rotate.
[0064] In one implementation, such as Figure 2 and Figure 3 As shown, the plug terminal 120 includes a large male plug terminal 121 and a small male plug terminal 122; the socket terminal 220 includes a large female socket terminal 221 and a small female socket terminal 222; after the plug assembly 100 and the socket assembly 200 are plugged in, the large male plug terminal 121 and the large female socket terminal 221 are connected, and the small male plug terminal 122 and the small female socket terminal 222 are connected.
[0065] Furthermore, the large male terminal 121 of the plug and the large female terminal 221 of the socket are current pins to enable power supply; the small male terminal 122 of the plug and the small female terminal 222 of the socket are signal pins to enable signal transmission.
[0066] In this connector, after the plug assembly 100 and the socket assembly 200 are inserted, the retaining ring 130 moves in the opposite direction to reset from the second position to the first position, thereby locking the plug assembly 100 and the socket assembly 200; when the plug assembly 100 and the socket assembly 200 are separated, only force needs to be applied as... Figure 5 As shown, rotating the pull ring 150 counterclockwise will cause the fixing ring 130 to move forward from the first position to the second position. While the fixing ring 130 continues to rotate forward, it will push the plug assembly 100 and the socket assembly 200 to separate.
[0067] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
