Description

Technical Field

[0001] The utility model relates to the field of cable connectors, and particularly to a waterproof connector. Background Art

[0002] When connecting and locking cables, the current cable connectors are prone to pinching the cables, or rotating when locking the cables, resulting in insufficiently tight cable connections. For example, a waterproof connector provided in Patent CN220400979U has a jaw type structure and is prone to the above problems.

[0003] Therefore, improvements must be made to address the above defects. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a waterproof connector to solve the problems in the background art.

[0005] To solve the above technical problem, the technical solution of the utility model is as follows:

[0006] A waterproof connector includes a main body, which includes a first external thread ring, a first hexagonal sleeve, and a second external thread ring connected in sequence from left to right. A nut and an O-ring are sequentially sleeved on the first external thread ring from left to right. A flared opening that gradually increases from left to right is provided at the right end inside the second external thread ring. A waterproof rubber plug is provided on the flared opening. A conical surface matching the flared opening is provided on the outer wall of the waterproof rubber plug. A locking hole penetrating the waterproof rubber plug from left to right is provided on the waterproof rubber plug. A cap is provided on the second external thread ring.

[0007] Further, a first rounded corner is provided at the connection between the right end face of the waterproof rubber plug and the outer wall of the waterproof rubber plug.

[0008] Further, a cable hole penetrating the cap from left to right is provided on the cap. A second rounded corner is provided at the connection between the right end face of the cap and the outer wall of the cap.

[0009] Further, a second hexagonal sleeve is provided in the middle of the outer surface of the cap.

[0010] Further, the nut is a hexagonal nut.

[0011] Further, an inner groove is provided on the right end face of the cap. An internal thread matching the second external thread ring is provided on the inner groove.

[0012] Further, the first external thread ring, the first hexagonal sleeve, and the second external thread ring are integrally formed.

[0013] Advantages of the Utility Model:

[0014] With the above technical solution, due to the structure of using a waterproof rubber plug and a cap to compress the cable, when locking the cable, the cable locking range is large; when the waterproof rubber plug compresses the cable under the extrusion of the cap, the cable will not be pinched, and the cable will not rotate with the tightening of the cap during locking, making the cable connection more secure; when disassembling and assembling, the waterproof rubber plug will not get stuck in the main body, making it convenient for disassembly and assembly.

[0022] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Refer to Figures 1 to 5The utility model provides a waterproof joint, including a main body, the main body including a first external thread ring 3, a first hexagonal sleeve 4 and a second external thread ring 5 connected in sequence from left to right, the first external thread ring 3 is sleeved with a nut 1 and an O-ring 2 in sequence from left to right, the right end of the inside of the second external thread ring 5 is provided with a bell mouth 11 that becomes larger from left to right, the bell mouth 11 is provided with a waterproof rubber plug 12, the outer wall of the waterproof rubber plug 12 is provided with a conical surface 6 that matches the bell mouth 11, the waterproof rubber plug 12 is provided with a locking hole 8 that passes through the waterproof rubber plug 12 from left to right, and the second external thread ring 5 is provided with a cap 9. The first hexagonal sleeve 4 is convenient for fixing and locking the main body and the cap 9 by a wrench.

[0024] The technical solution adopts a structure in which the waterproof rubber plug 12 cooperates with the cover cap 9 to compress the cable, so that when locking the cable, the locking range is large; when the waterproof rubber plug 12 compresses the cable under the squeezing action of the cover cap 9, the cable will not be pinched, and the cable will not rotate as the cover cap 9 is tightened during locking, and the cable connection is tighter; when disassembling and assembling, the waterproof rubber plug will not be stuck in the main body, and disassembly and assembly are convenient.

[0025] For example, in some embodiments, a first rounded corner 7 is provided at the connection between the right end surface of the waterproof rubber plug 12 and the outer wall of the waterproof rubber plug 12. The first rounded corner 7 can prevent the sharp corner from damaging the inner side of the cap 9 and affecting the fastening performance of the connection.

[0026] For example, in some embodiments, the cap 9 is provided with a cable hole 14 that passes through the cap 9 on the left and right sides, and a second rounded corner 13 is provided at the connection between the right end surface of the cap 9 and the outer wall of the cap 9. This can prevent sharp corners from causing harm to operators.

[0027] For example, in some embodiments, a second hexagonal sleeve 10 is provided in the middle of the outer surface of the cap 9. This makes it easier to lock the cap 9 with a wrench.

[0028] For example, in some embodiments, the nut 1 is a hexagonal nut, which makes it easy to tighten the nut 1 with a wrench.

[0029] For example, in some embodiments, the right end surface of the cap 9 is provided with an inner groove, and the inner groove is provided with an inner thread that matches the second outer thread ring 5. Figures 4 - 5 As described above, during use, if the cable is large, the number of turns of the cap 9 tightened will be relatively small. If the cable is small, the number of turns of the cap 9 tightened will be relatively large, and the cable needs to be locked by squeezing the waterproof rubber plug 12.

[0030] For example, in some embodiments, the first external thread ring 3, the first hexagonal sleeve 4 and the second external thread ring 5 are integrally formed, so as to ensure overall stability.

[0031] In summary, the utility model adopts a structure in which a waterproof rubber plug cooperates with a cap to press the cable tightly. In this way, when locking the cable, the cable locking range is large; when the waterproof rubber plug presses the cable under the extrusion of the cap, the cable will not be pinched, and the cable will not rotate with the tightening of the cap during locking, making the cable connection more firm; during disassembly and assembly, the waterproof rubber plug will not be stuck in the main body, making disassembly and assembly convenient.

[0032] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
