Description

Technical Field

[0001] This utility model relates to the field of electrical connection connector technology, and in particular to a locking ring assembly and an electrical connection connector. Background Technology

[0002] Electrical connectors are used for the transmission of current and signals in cables, forming a connection through the insertion of male and female connectors. To ensure the stability of the connection, traditional techniques typically use nuts for locking. However, the reliability and stability of these nuts are still insufficient to meet current needs, as they are prone to loosening, leading to problems such as unstable telecommunication transmission and waterproofing failure. Furthermore, they are very inconvenient to install and remove. Utility Model Content

[0003] In view of the above situation, it is necessary to propose a locking ring assembly and electrical connection connector that can prevent loosening of the connection and allow for quick assembly and disassembly.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a locking ring assembly, comprising:

[0005] The outer ring has an inwardly extending retaining ring on its front end face, the retaining ring having a plurality of inwardly extending first blocks, and the inner wall of the outer ring having a limiting groove.

[0006] The inner ring has a protrusion on the outer wall of the outer ring, and a limiting protrusion that can slide back and forth in the limiting groove on the protrusion. The inner ring has a sliding notch corresponding to the first stop block. The sliding notch opens forward, and the inner wall of the inner ring has a second stop block behind the sliding notch.

[0007] An elastic element is disposed between the outer ring and the inner ring. One end of the elastic element abuts against the retaining ring, and the other end abuts against the end face of the protrusion. The elastic element has a restoring force when the first stop block moves closer to the second stop block.

[0008] Furthermore, the outer wall of the outer ring has a protrusion at its rear end.

[0009] Furthermore, the outer wall of the outer ring is provided with several hand-loop grooves.

[0010] Furthermore, the inner wall of the inner ring has an inner convex ring at its rear end.

[0011] Furthermore, the inner wall of the outer ring is provided with a plurality of protruding walls, and the protrusions of the inner ring are provided with slots corresponding to the protruding walls, and the protruding walls are inserted into the slots.

[0012] Furthermore, several first stop blocks are arranged symmetrically or in a circular array, and the sliding notch and the second stop block are arranged corresponding to the first stop blocks.

[0013] An electrical connector, characterized in that it includes the aforementioned locking ring assembly, and further includes a male connector and a female connector, one of which is sleeved within the locking ring assembly, and the other has a retaining groove on its outer end wall. The retaining groove includes a communicating inlet groove, a guide groove, and a retaining groove. The inlet groove opens towards its front end, the front end of the guide groove communicates with the inlet groove, and the side portion of its tail end communicates with the retaining groove. The retaining groove has a blocking portion extending beyond the guide groove in a front-rear direction. When the first stop and the second stop are brought close together by an external force, they are allowed to pass through the guide groove. When the first stop and the second stop are located within the retaining groove and no external force is applied, the blocking portion is close to the side wall of the guide groove, blocking the first stop and / or the second stop. The male connector is connected to the female connector.

[0014] Furthermore, a guide protrusion is provided at the bottom of the guide groove near the slot groove. Both sides of the guide protrusion have guide surfaces, which are arc surfaces or inclined surfaces. The length of the guide surface on the side of the guide protrusion away from the slot groove is greater than the length of the guide surface on the side closer to the slot groove.

[0015] Furthermore, both sides of the inlet groove are inclined or curved surfaces, causing the width of the inlet groove to gradually decrease towards the rear.

[0016] Furthermore, a limiting block is provided at the front end of the slot, the limiting block extends into the inlet slot, and the surfaces of the limiting block facing the inlet slot and the guide slot are both inclined or curved surfaces.

[0017] The beneficial effects of this utility model are as follows: the outer ring and inner ring of the locking ring assembly are slidably nested, and the inner ring is used to connect one of the male or female heads. When there is no external force, the first stop and the second stop move away from each other under the action of the elastic element, and the distance between them is large; under the action of external force, the first stop and the second stop move closer to each other, and the distance between them becomes smaller. When the male and female connectors are mated, the outer ring slides, and the first and second stops move closer together, reducing their distance. Rotating the locking ring assembly allows the first and second stops, after mating, to enter the locking groove through the guide groove. Once in the locking groove, the outer ring is released, increasing the distance between the first and second stops. The blocking part then blocks the first and / or second stops, locking them in place. Similarly, disassembly is performed in reverse order: the outer ring must be moved axially with continuous force while simultaneously holding the male or female connector with the locking groove and rotating the locking ring assembly. Axial movement, rotational movement, touching only the locking ring assembly, or touching only the male / female connector will not unlock the connection. The locking groove also prevents loosening in the axial direction, ensuring a stable and reliable connection, and facilitating quick and easy assembly and disassembly. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a locking ring assembly and electrical connection connector of this utility model, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0035] Please refer to Figures 1-8 A locking ring assembly 100 includes:

[0036] The outer ring 110 has an inwardly extending retaining ring 111 on its front end face. The retaining ring 111 has a plurality of inwardly extending first stops 1111. The inner wall of the outer ring 110 is provided with a limiting groove 112.

[0037] The inner ring 120 and the outer ring 110 have a protrusion 121 on their outer walls. A limiting protrusion 122 that can slide back and forth in the limiting groove 112 is provided on the protrusion 121. The inner ring 120 has a sliding notch 123 corresponding to the first stop 1111. The sliding notch 123 opens forward. The inner wall of the inner ring 120 has a second stop 124 behind the sliding notch 123.

[0038] The elastic element 130 is disposed between the outer ring 110 and the inner ring 120. One end of the elastic element 130 abuts against the retaining ring 111 and the other end abuts against the end face of the protrusion 121. When the first stop block 1111 approaches the second stop block 124, the elastic element 130 has a restoring force.

[0039] The outer ring 110 and inner ring 120 of the locking ring assembly 100 are slidably nested. The inner ring 120 is used to connect one of the male connector 200 or the female connector 300. Without external force, the first stop 1111 and the second stop 124 are far apart under the action of the elastic element 130, with a large distance between them. Under external force, the first stop 1111 and the second stop 124 are close together, and the distance between them decreases. When the male connector 200 and the female connector 300 are mated, the outer ring 110 is slid, and the first stop 1111 and the second stop 124 are close together, with a smaller distance between them. Rotating the locking ring assembly 100, the inlet groove 311 of the mated first stop 1111 and the second stop 124 enters the locking groove 313 through the guide groove 312. After entering the locking groove 313, the outer ring 110 is released, and the distance between the first stop 1111 and the second stop 124 increases. The blocking part 3131 blocks the first stop 1111 and / or the second stop 124. Alternatively, the second stop 124 can be used for locking. Similarly, disassembly is performed in the opposite manner, that is, the outer ring 110 needs to be moved axially and force is applied continuously. At the same time, the male head 200 or female head 300 with the slot 310 is held and the locking ring assembly 100 is rotated. Axial movement, rotational movement, touching the locking ring assembly 100, or touching the male head 200 / female head 300 will not unlock the device. The axial direction will not loosen due to the limitation of the slot 313. The connection is stable, reliable, and easy and quick to assemble and disassemble.

[0040] Please refer to Figure 1 The outer ring 110 has a protrusion 114 at the rear end of its outer wall. The protrusion 114 at the rear end of the outer wall allows the outer ring 110 to be moved backward easily.

[0041] Please refer to Figure 1 The outer ring 110 has several hand-holding grooves 115 on its outer wall. Preferably, there are multiple hand-holding grooves 115, which can be arranged symmetrically or in a circular array. The hand-holding grooves 115 facilitate the movement of the outer ring 110 and also facilitate rotational force application.

[0042] Please refer to Figure 1 The inner wall of the inner ring 120 has an inner convex ring 125 at its rear end. The inner convex ring 125 facilitates the installation of the male connector 200 or the female connector 300, that is, the inner convex ring 125 supports the male connector 200 or the female connector 300.

[0043] Please refer to Figure 2 The inner wall of the outer ring 110 is provided with several protruding walls 116, and the protrusions 121 of the inner ring 120 are provided with slots 126 corresponding to the protruding walls 116, and the protruding walls 116 are inserted into the slots 126. Through the cooperation of the protruding walls 116 and the slots 126, on the one hand, the stability of the back-and-forth movement is further ensured, and on the other hand, it is convenient for the outer ring 110 to transmit the rotational torque to the inner ring 120.

[0044] Preferably, several first stop blocks 1111 are arranged in a symmetrical or circular array, and sliding notches 123 and second stop blocks 124 are arranged correspondingly to the first stop blocks 1111. The symmetrical or circular array arrangement improves the stability and strength of the connection. Preferably, three first stop blocks 1111, second stop blocks 124, and sliding notches 123 are arranged in a circular array.

[0045] The elastic element 130 can be a sheet or a spring as needed. When a sheet is used, the sheets are arranged in a ring array, and a limiting mounting groove is provided between the outer ring 110 and the inner ring 120.

[0046] Preferably, in order to facilitate the entry of the limiting protrusion 122 into the limiting groove 112, a transition groove 113 is usually provided behind the limiting groove 112. A partition protrusion 1131 is provided between the transition groove 113 and the limiting protrusion 122. The side of the partition protrusion 1131 facing the transition groove 113 has a transition slope or transition arc surface to facilitate the entry of the limiting protrusion 122 into the limiting groove 112 during assembly.

[0047] Please refer to Figures 1-8 An electrical connector includes the aforementioned locking ring assembly 100, and further includes a male connector 200 and a female connector 300. One of the male connector 200 and the female connector 300 is sleeved within the locking ring assembly 100, and the other has a slot 310 on its outer wall at its end. The slot 310 includes a communicating inlet slot 311, a guide slot 312, and a locking slot 313. The inlet slot 311 opens towards its front end, and the front end of the guide slot 312 communicates with the inlet slot 311, while the side of its rear end communicates with the locking slot. The slot 313 has a blocking portion 3131 that extends beyond the guide slot 312 in the front-back direction; when the first stop 1111 and the second stop 124 are brought close together by an external force, the guide slot 312 is allowed to pass through; when the first stop 1111 and the second stop 124 are located in the slot 313 and no external force is applied, the blocking portion 3131 is close to the side wall of the guide slot 312 to block the first stop 1111 and / or the second stop 124, and the male head 200 is connected to the female head 300.

[0048] Furthermore, a guide protrusion 3121121 is provided at the bottom of the guide groove 312 near the locking groove 313. Both sides of the guide protrusion 3121121 have guide surfaces, which are either curved or inclined. The length of the guide surface on the side of the guide protrusion 3121121 away from the locking groove 313 is greater than the length of the guide surface on the side closer to the locking groove 313. The guide protrusion 3121121 provides a tactile feedback when the first stop 1111 and the second stop 124 pass through, serving as a reminder. The difference in the length of the guide surface of the guide protrusion 3121121 makes assembly easier, while requiring greater force for disassembly, thus preventing loosening and improving stability.

[0049] Furthermore, both sides of the inlet groove 311 are inclined or curved surfaces, causing the width of the inlet groove 311 to gradually decrease rearward. Preferably, the inclination of the inlet groove 311 on one side of the limiting block 314 is less than the inclination on the other side. The funnel-shaped inlet groove 311 facilitates the entry of the first stop block 1111 and the second stop block 124 into the inlet groove 311 and smoothly guides them to the guide groove 312.

[0050] Furthermore, a limiting block 314 is provided at the front end of the slot 313. The limiting block 314 extends into the inlet slot 311, and the surfaces of the limiting block 314 facing the inlet slot 311 and the guide slot 312 are both inclined or curved surfaces. The limiting block 314 further improves reliability, and its shape design facilitates left and right assembly.

[0051] Preferably, the male connector 200 or female connector 300 assembled within the locking ring assembly 100 can be fixedly connected to the locking ring assembly 100, or it can be detachably connected. The fixed connection can be achieved by welding, gluing, or integral molding. Specifically, the inner ring 120 of the locking ring assembly 100 can be directly integrally molded as part of the female connector 300. Further, the male connector 200 or female connector 300 assembled within the locking ring assembly 100 has a support portion 230 that supports the inner convex ring 125. Preferably, a sealing ring 210 is fitted onto the convex portion 114; specifically, the sealing ring 210 is a stepped sealing ring 210.

[0052] Preferably, the male connector 200 and the female connector 300 have a foolproof positioning structure to ensure that the male connector 200 and the female connector 300 are correctly aligned in the circumferential position. Alternatively, the outline of the male connector 200 or the female connector 300 can be non-circular, or asymmetrical positioning protrusions 220121 and positioning grooves 320 can be provided on the male connector 200 and the female connector 300. More specifically, at least one asymmetrical positioning groove 320 is provided on the inner wall of the female connector 300, and a corresponding asymmetrical positioning protrusion 220 is provided on the outer wall of the male connector 200, with the positioning protrusion 220 and the positioning groove 320 being inserted and fitted together.

[0053] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Generally, the end of the male connector closer to the female connector is "front", and the end farther from the female connector is "back"; the end of the female connector closer to the male connector is "front", and the end farther from the male connector is "back".

[0054] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0055] In summary, the locking ring assembly and electrical connector provided by this utility model allow for the following connection: When the male and female connectors are mated, the sliding outer ring causes the first and second stops to approach each other, reducing their distance. Rotating the locking ring assembly allows the first and second stops, after being engaged, to enter the locking groove through the guide groove. Once in the locking groove, releasing the outer ring increases the distance between the first and second stops, and the blocking part blocks the first and / or second stops, thus locking them in place. Similarly, disassembly is performed in reverse order, requiring axial movement of the outer ring with continuous force while simultaneously holding the male or female connector with the locking groove and rotating the locking ring assembly. Axial movement, rotational movement, touching the locking ring assembly, or touching the male / female connector alone will not unlock the connection. The locking groove also prevents loosening in the axial direction, ensuring a stable and reliable connection, and facilitating quick and easy assembly and disassembly.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
