[0001] This utility model relates to the field of signal line connector technology, and more specifically to a waterproof connector with a self-locking mechanism. Background Technology

[0002] When wiring signal lines in network devices, connectors are required for assembly. Connectors are used to disconnect and connect devices and wire harnesses, or to disconnect and connect wire harnesses to each other.

[0003] According to the publication (announcement) number: CN206271957U, the publication (announcement) date: 2017-06-20, a waterproof signal line connector is disclosed, including a connector female head and a connector male head, and the electrical connection between the two is achieved by a socket and plug sliding assembly, and then tightened by threads.

[0004] In the prior art, including the aforementioned patents, the common connectors on the market involve inserting a male and female head together, and then using a ring with internal threads to cover and tighten the connection end. After rotation, the threads provide a tightening effect, and the ring protects the insertion position. However, the tightening method of threaded connection requires multiple rotations, and before rotation, it is necessary to deal with the slippage problem caused by misalignment of the threads. This makes the installation and docking process time-consuming and cannot meet the needs of emergency wiring and disconnection. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof connector with a self-locking mechanism, which aims to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof connector with a self-locking mechanism includes a female connector with a socket and a male connector with a plug, and also includes a ring that slides on the outer side wall of the male connector, wherein the inner side wall of the ring is provided with a second elastic piece arranged circumferentially and located in the inner side wall of the male connector.

[0008] In its default state, the second elastic piece causes the protrusion fixedly installed on it to fit into the recess opened on the inner sidewall of the female head;

[0009] The male end has a limiting hole for the second elastic sheet to slide out and for releasing the clamping of the female end.

[0010] Preferably, it further includes a first elastic piece fixedly installed on the inner side wall of the ring and connected to the second elastic piece, and the first elastic piece and the second elastic piece are elastically connected.

[0011] Preferably, an inner inclined plate that guides the sliding of the first elastic plate is fixedly installed inside the limiting hole port.

[0012] Preferably, the inner inclined plate has an elastic end fixedly installed at its end that abuts against the second elastic plate.

[0013] Preferably, the inner sidewall of the ring is fixedly equipped with a plurality of pressure blocks arranged opposite to the protrusion.

[0014] Preferably, the outer wall of the female head is provided with a pressure groove that engages with the pressure block.

[0015] Preferably, a plurality of sliders are fixedly installed on the outer side wall of the male head, and a groove is provided at the end of the ring sleeve to slide and cooperate with the sliders.

[0016] Preferably, the groove has an opening that is disposed opposite to the second elastic sheet.

[0017] Preferably, a sealing ring that mates with the pressure block is fixedly installed at the male end.

[0018] Preferably, the sealing ring is a rubber ring.

[0019] In the above technical solution, the waterproof connector with a self-locking mechanism provided by this utility model has the following beneficial effects: the ring slides axially on the outer wall of the female head, and the second elastic piece undergoes deformation and reset steps, so that the reset second elastic piece uses the protrusion to lock onto the inner wall of the female head, so that the ring can self-lock with the female head after it is in place, achieving the convenient purpose of plug and play. When unlocking, the ring is pulled away from the female head and slid, and then the second elastic piece is guided by the limiting hole to deflect, and the protrusion opens the recess to achieve unlocking, resulting in a connector that can be quickly disassembled and assembled, greatly shortening the time spent in the installation and docking process.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a waterproof connector with a self-locking mechanism includes a female head 1 with a socket 11 and a male head 2 with a plug 21, and also includes a ring 3 that slides on the outer side wall of the male head 2. The inner side wall of the ring 3 is provided with a second elastic piece 33 arranged in a circle and located in the inner side wall of the male head 2.

[0029] In its default state, the second elastic piece 33 causes the protrusion 34 fixedly installed on it to fit into the recess opened on the inner side wall of the female head 1;

[0030] The male head 2 has a limiting hole 23 for the second elastic piece 33 to slide out and for releasing the clamping of the female head 1.

[0031] Specifically, the connection and communication between the socket 11 and the plug 21 is existing technology and will not be described in detail here. Multiple strip-shaped grooves are provided on the outer wall of the ring sleeve 3 to increase the contact friction with the outer wall of the ring sleeve 3.

[0032] Furthermore, the female connector 1 and the male connector 2 have radial space at their ends after the socket 11 and plug 21 are inserted, so that the elastic components have enough space to deform. The second elastic piece 33 is specifically an elastic metal piece, and the second elastic piece 33 is inclined toward the inner wall of the ring 3 in the default state.

[0033] When the male connector 2 is inserted into the female connector 1, the ring 3 slides axially against the outer wall of the female connector 1, accompanied by the deformation and reset of the second elastic piece 33. After reset, the second elastic piece 33 uses the protrusion 34 to lock against the inner wall of the female connector 1, so that the ring 3 can self-lock with the female connector 1 after it is in place, achieving the convenient purpose of plug and play. When unlocking, the ring 3 is pulled away from the female connector 1 and slid. Then the second elastic piece 33 is guided and deflected by the limiting hole 23, and the protrusion 34 opens the recess to unlock, thus obtaining a connector that can be quickly disassembled and assembled, greatly shortening the time spent in the installation and docking process.

[0034] As a further embodiment of this utility model, it also includes a first elastic piece 32 fixedly installed on the inner side wall of the ring sleeve 3 and connected to the second elastic piece 33, and the first elastic piece 32 and the second elastic piece 33 are elastically connected.

[0035] Specifically, the first elastic piece 32 and the second elastic piece 33 form an obtuse angle, and the angle of the obtuse angle increases as the first elastic piece 32 moves out of the limiting hole 23.

[0036] As the first elastic piece 32 slides out of the limiting hole 23 as the ring 3 moves away, the first elastic piece 32 pulls the second elastic piece 33 to make the obtuse angle tend to be a flat angle. Therefore, the end of the second elastic piece 33 must be deflected towards the axis, so that the protrusion 34 is driven away from the recess to achieve the unlocking operation.

[0037] As another embodiment provided by this utility model, an inner inclined piece 24 for guiding the sliding of the first elastic piece 32 is fixedly installed inside the port of the limiting hole 23.

[0038] Specifically, the inner inclined plate 24 is a hard alloy metal plate that will not deform when compressed.

[0039] The obtuse-angle vertex is provided by the surface of the inner inclined plate 24 so that the first elastic plate 32 provides stable tension to the second elastic plate 33, facilitating the unlocking operation.

[0040] As another embodiment further provided by this utility model, the end of the inner inclined plate 24 is fixedly mounted with an elastic end 25 that abuts against the second elastic plate 33.

[0041] Specifically, the connection position between the elastic end 25 and the inner bevel piece 24 can deform, and the elastic end 25 is biased away from the axis of the male head 2 in the default state.

[0042] When the second elastic sheet 33 is used for clamping and locking, the elastic end 25 is pressed against the reset deformation direction of the second elastic sheet 33, so that the elastic end 25 can provide a further compaction function.

[0043] As another embodiment provided in this utility model, a plurality of pressure blocks 35 are fixedly installed on the inner sidewall of the ring sleeve 3 and arranged opposite to the protrusion 34.

[0044] Under the clamping capability of the second elastic sheet 33, the relatively arranged protrusions 34 and pressure blocks 35 can provide multi-point clamping for the side wall of the female head 1, making the docking stability higher and less prone to separation.

[0045] As another embodiment provided in this utility model, a pressure groove 12 is provided on the outer side wall of the female head 1 to engage with the pressure block 35.

[0046] Specifically, the insertion of the pressure block 35 and the pressure groove 12 takes place before the insertion of the socket 11 and the plug 21.

[0047] The groove 12 ensures that the clamping block 35 can be fitted and installed, and also facilitates the precise docking of the ring 3, making it less likely for the plug 21 and the socket 11 to have misalignment.

[0048] As another embodiment of this utility model, a plurality of sliders 22 are fixedly installed on the outer side wall of the male head 2, and a groove 31 is provided at the end of the ring sleeve 3 to slide and cooperate with the sliders 22.

[0049] By connecting the slider 22 and the groove 31, the ring sleeve 3 can have a guiding and limiting function during axial movement, making the movement of the ring sleeve 3 more stable and the connection more precise.

[0050] As another embodiment of the present invention, the groove 31 has an opening disposed opposite to the second elastic piece 33.

[0051] Specifically, the opening formed by the second elastic piece 33, the first elastic piece 32, and the ring 3 faces away from each other, allowing for installation by sliding on one side.

[0052] When the angle is reduced from an obtuse angle to an acute angle, the ring sleeve 3 is slid away from the slider 22 with force. At this time, the second elastic piece 33 can be pulled out from the limiting hole 23. The sum of the thickness between the arc top of the protrusion 34 and the end face of the second elastic piece 33 matches the distance between the inner inclined piece 24 and the inner side of the port of the limiting hole 23. The purpose is to facilitate the pulling out of the second elastic piece 33 for the replacement of the ring sleeve 3. This is suitable for connectors that are frequently disassembled and assembled, while connectors that are used for a long time do not need to be replaced due to wear of the ring sleeve 3.

[0053] As another embodiment provided in this utility model, a sealing ring 36 that cooperates with the pressure block 35 is fixedly installed at the end of the male head 2.

[0054] After the male connector 2 and the female connector 1 are inserted, the sealing ring 36 abuts against the port of the female connector 1 to waterproof and seal the connection position. At the same time, the sealing ring 36 also blocks the positions of multiple pressure blocks 35 on the outside and uses the pressure blocks 35 to provide a path for intruding dust, that is, to retain some dust and reduce the possibility of dust seeping into the sealing ring 36.

[0055] As another embodiment further provided in this utility model, the sealing ring 36 is specifically a rubber ring.

[0056] The rubber ring improves the sealing effect of the sealing ring 36, and when the disengaged ring 3 is subjected to external impact, it can absorb energy and buffer the impact using two elastic sheets and elastic end 25. At the same time, the pressure block 35 can also abut against the sealing ring 36 to reach the impact termination position, so that the ring 3 can always be on the outside of the male connector 2 port, and can also provide a certain degree of protection for the plug 21.

[0057] Working principle: When the male head 2 is inserted into the female head 1, the ring sleeve 3 slides axially on the outer wall of the female head 1, and the second elastic piece 33 undergoes deformation and reset steps. After reset, the second elastic piece 33 uses the protrusion 34 to lock onto the inner wall of the female head 1, so that the ring sleeve 3 can self-lock with the female head 1 after it is in place. When unlocking, the ring sleeve 3 is pulled away from the female head 1 and slids. Then the second elastic piece 33 is guided to deflect by the limiting hole 23, and the protrusion 34 opens the recess to achieve unlocking.

[0058] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
