Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a waterproof connection structure. Background Technology

[0002] In fields such as electronic equipment, industrial automation, automotive manufacturing, and outdoor communications, the reliability and environmental adaptability of cable connectors are crucial. Among them, waterproof connectors that can effectively prevent the intrusion of moisture and dust are key to ensuring the stable operation of equipment.

[0003] Currently, the waterproof connectors widely used in the market typically include a first end seat and a second end seat in their structural design. The two are connected and separated by a locking mechanism. A common and mature technical solution is to use a nut locking structure. Specifically, this structure usually has a threaded part on the first or second end seat and is tightened by an external threaded nut. The axial preload generated by the threaded pair is used to firmly press the two end seats together, and waterproof sealing is achieved in conjunction with sealing rings and other components.

[0004] However, in practical applications, the connector may directly withstand significant external pressure or be subjected to strong physical impacts. In such cases, the nut may be crushed or deformed due to direct pressure, or break or strip due to severe impact. Once the nut suffers such damage, its original locking function will be completely lost, resulting in the loss of effective fastening force between the first and second end seats. This may not only cause the connection to loosen or even completely separate, but also cause the original waterproof sealing structure to fail.

[0005] Based on this, in order to further optimize the connection reliability of existing connectors, we propose a waterproof connection structure. Utility Model Content

[0006] The purpose of this utility model is to solve the shortcomings of the existing technology, such as nuts being crushed or deformed due to direct pressure, or breaking or stripping due to violent impact, resulting in connection failure, and to propose a waterproof connection structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Design a waterproof connection structure, including: A first endplate with a male connector and a second endplate with a female connector are provided, the outer side of the second endplate having a foolproof notch; The first end seat and the second end seat are connected and fixed by a locking member. An inner locking assembly is also installed on the end face of the first end seat, and a locking ring is embedded on the end face of the second end seat. The inner locking assembly and the locking ring are locked and fixed.

[0008] Furthermore, the locking element includes a nut sleeve that is slidably connected to the outside of the first end seat; A stop is provided at the outer end of the first end seat, and the inner side of the nut sleeve abuts against the stop. The nut sleeve and the second end seat are threadedly connected.

[0009] Furthermore, at least one slot is provided on the outer side of the first end seat, and a first pawl is formed in the slot, the first pawl stopping at the end of the locking member.

[0010] Furthermore, the internal locking assembly includes a tube fixedly mounted on the first end seat; An abutment rod is movably inserted inside the insertion tube. The outer side of the first end seat has a groove. One end of the abutment rod extends into the groove. A positioning bead is movably connected to the outer side of the insertion tube. The outer side of the abutment rod has an inner retractable annular groove for accommodating the positioning bead.

[0011] Furthermore, the locking ring has a ring groove in the middle, and the positioning bead engages with the ring groove.

[0012] Furthermore, a limiting groove is provided in the groove, and a second claw is formed in the limiting groove, the second claw stopping at the end of the abutment rod.

[0013] Furthermore, the male and female connectors are configured as USB or YPYE-C connectors, and the male connector is compatible with the female connector.

[0014] The waterproof connection structure proposed in this utility model has the following advantages: Based on the connection between the first end seat and the second end seat using a locking component, this utility model adds an internal locking component to the end face of the first end seat and a locking ring to the end face of the second end seat.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 As an embodiment of this utility model, a waterproof connection structure is disclosed. Specifically, the connection structure includes a first end seat 1 with a male connector 10 and a second end seat 2 with a female connector 20. The outer side of the second end seat 2 has a foolproof opening 21. Of course, both the male connector 10 and the female connector 20 are connected to wires. In this embodiment, the male connector 10 and female connector 20 are configured as USB connectors or YPYE-C connectors. Specifically, the male connector 10 and female connector 20 can be male and female connectors of USB connectors or male and female connectors of YPYE-C connectors. The male connector 10 and the female connector 20 are compatible. The keying notch 21 on the side of the second end seat 2 can prevent problems such as reverse insertion when the first end seat 1 and the second end seat 2 are connected. Of course, in order to accommodate the keying notch 21, an indicator mark, such as a raised mark or text mark, can also be set on the outside of the first end seat 1 to ensure a stable and accurate connection between the first end seat 1 and the second end seat 2. Obviously, through the design of the keying notch 21, the entire second end seat 2 forms a D-shaped shape.

[0019] The first end seat 1 and the second end seat 2 are connected and fixed by a locking member 3. An inner locking component 4 is also installed on the end face of the first end seat 1, and a locking ring 5 is embedded on the end face of the second end seat 2. The inner locking component 4 and the locking ring 5 are locked and fixed.

[0020] In some embodiments, the locking member 3 of the present invention includes a nut sleeve that is slidably connected to the outside of the first end seat 1; A stop plate 11 is provided at the outer end of the first end seat 1, and the inner side of the nut sleeve abuts against the stop plate 11, wherein the nut sleeve and the second end seat 2 are threadedly connected.

[0021] When connecting the first end seat 1 and the second end seat 2, the male head 10 on the first end seat 1 and the female head 20 on the second end seat 2 can be inserted first. After the insertion is completed, the nut sleeve is rotated. With the help of the threaded connection force of the nut sleeve and the second end seat 2, the locking and fixing between the first end seat 1 and the second end seat 2 can be completed.

[0022] In addition, a sealing gasket can be provided between the first end seat 1 and the second end seat 2 to improve the waterproof effect. The end face of the sealing end should be provided with a clearance opening to avoid interference with the connection between the first end seat 1 and the second end seat 2. This method is a conventional method for those skilled in the art and will not be elaborated further.

[0023] Based on the above embodiments, in this embodiment, at least one slot is provided on the outer side of the first end seat 1, and a first claw 12 is formed in the slot. The first claw 12 stops at the end of the locking member 3. Specifically, the first claw 12 provided in this embodiment is used to stop the nut sleeve. Of course, the claw end of the first claw 12 has a bevel. When the nut sleeve moves in, it will abut against the bevel to drive the first claw 12 to retract until the nut sleeve is threaded and the first claw 12 pops out and resets and stops at the side of the nut sleeve. This design can avoid the problem of the nut sleeve loosening and moving backward after the connection is completed, thereby further optimizing the stability of the first end seat 1 and the second end seat 2 after connection.

[0024] Of course, when separating the first end seat 1 and the second end seat 2, you can first press down on the first pawl 12 to make it retract, and then rotate the nut sleeve in the opposite direction to make it move backward and separate from the second end seat 2.

[0025] Preferably, the inner locking component 4 in this embodiment includes a tube 41 fixedly installed on the first end seat 1, and the tube 41 in this embodiment can be configured as two tubes; An abutment rod 42 is movably inserted inside the insertion tube 41. The outer side of the first end seat 1 has a groove 13. One end of the abutment rod 42 extends into the groove 13. A positioning bead 43 is movably connected to the outer side of the insertion tube 41. That is, in this embodiment, a ball bearing hole is provided on the outer side of the insertion tube 41. The outer diameter of the ball bearing hole is smaller than the diameter of the positioning bead 43, so as to prevent the positioning bead 43 from falling out of the ball bearing hole. The outer side of the abutment rod 42 has an inner recessed annular groove 44 to accommodate the positioning bead 43.

[0026] Furthermore, in order to achieve locking adaptation with the positioning bead 43, the locking ring 5 in this embodiment has a ring groove 51 in the middle, and the positioning bead 43 is engaged with the ring groove 51. Of course, the locking ring 5 is fixedly installed in the end face of the second end seat 2.

[0027] Specifically, in order to achieve the connection between the first end seat 1 and the second end seat 2, in addition to the male head 10 and the female head 20 being inserted and matched, the insertion tube 41 is also inserted into the inside of the locking ring 5. During the insertion process, the aforementioned abutment rod 42 can be pulled outward so that the inner retracting ring groove 44 on the outer side of the abutment rod 42 and the positioning bead 43 are opposite. At this time, since the positioning bead 43 has radial movement space, the positioning bead 43 can retract inward. When the insertion tube 41 is inserted into the locking ring 5, the positioning bead 43 can retract freely to ensure the stable insertion of the insertion tube 41 and the locking ring 5. After insertion, the abutment rod 42 can be pushed inward, and the outer wall of the abutment rod 42 abuts against the positioning bead 43, thereby driving the positioning bead 43 to move outward. At this time, the positioning bead 43 moves outward due to the abutment of the outer wall of the abutment rod 42 and protrudes outward. This part is engaged in the ring groove 51 of the locking ring 5. In this way, the entire insertion rod 41 and the locking ring 5 can be internally locked between the end faces of the first end seat 1 and the second end seat 2. This design can greatly improve the connection stability between the first end seat 1 and the second end seat 2 and avoid the problem of connection failure due to damage to the locking part 3.

[0028] Of course, in order to ensure the positional stability of the abutment rod 42 when locked, a limiting groove is also provided in the groove position 13 in this embodiment. A second claw 14 is formed in the limiting groove, and the second claw 14 stops at the end of the abutment rod 42.

[0029] Similarly, in this embodiment, the second claw 14 is used to stop and limit the end of the abutment rod 42, so that when the abutment rod 42 abuts the positioning bead 43, its position can always remain fixed. Of course, when separating, the nut sleeve can be removed first, and the nut sleeve can be slid outward to interfere with the second claw 14. At this time, due to the cooperation of the inner locking assembly 4 and the locking ring 5, the first end seat 1 and the second end seat 2 are still locked and fixed. The second claw 14 can be pressed to retract it, and then the abutment rod 42 can be pulled outward. At this time, the inner retraction ring groove 44 at the end of the abutment rod 42 and the positioning bead 43 are arranged opposite to each other. With the help of the radial movement space of the positioning bead 43, the first end seat 1 and the second end seat 2 can be separated to complete the disassembly. The operation is simple and convenient, and at the same time, it greatly improves the connection stability between the first end seat 1 and the second end seat 2.

[0030] In summary, this utility model, based on the connection of the first end seat 1 and the second end seat 2 using locking member 3, adds an inner locking component 4 to the end face of the first end seat 1 and a locking ring 5 to the end face of the second end seat 2. The inner locking component 4 and the locking ring 5 internally lock the first end seat 1 and the second end seat 2, thereby further improving the connection stability between the first end seat 1 and the second end seat 2. This avoids the problem of connection failure caused by damage to the locking member 3.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
