Description

Technical Field

[0001] The present application relates to the field of cable technology, and in particular to a coaxial cable connector. Background Art

[0002] Coaxial cable refers to a cable with two concentric conductors, and the conductors and shielding layer share the same axis. The most common coaxial cable is composed of copper wire conductors isolated by insulating materials. Outside the inner insulating material is another layer of annular conductor and its insulator, and then the entire cable is wrapped by a sheath of polyvinyl chloride or Teflon material.

[0003] The existing patent (publication number: CN211238737U) has published a coaxial cable connector, including a male head and a female head, the surface of the male head is integrally molded with a first connection cover, the top and bottom of the first connection cover are fixedly connected to the limit column at 180 degrees to each other, the front and rear sides of the female head surface are provided with guide grooves, and the surface of the female head is provided with an annular groove at 90 degrees to the guide groove. The utility model sets a guide block to slide in the guide groove and the annular groove, so that the second connection cover is clamped on the limit column on the first connection cover through the horizontal groove and the vertical groove, thereby avoiding the loosening of the connection between the male head and the female head. At the same time, the first sealing gasket and the second sealing gasket play a sealing role, and the high temperature resistant and anti-oxidation layer plays a role of high temperature resistance and anti-oxidation, solving the problem that the connection of the existing cable connector cannot prevent falling off and the sealing gasket does not have high temperature resistance and anti-oxidation, thereby ensuring the normal use of the cable connector.

[0004] The above-mentioned connector is inserted into the limit column through the transverse groove on the second connecting cover, and then the second connecting cover is rotated counterclockwise. The guide block slides in the annular groove and drives the limit column to be inserted into the vertical groove. However, its limit column lacks a limit mechanism. When the cable is dragged, the limit column is easily moved to the transverse groove, causing the connection end to become loose. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a coaxial cable connector having the advantages of stable connection and easy disassembly, and solves the problem that its limit column lacks a limit mechanism. When the cable is dragged, the limit column is easily displaced to the horizontal groove, causing the connection end to become loose.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a coaxial cable connector, comprising a male head and a female head, wherein the outer surface of the male head is fixedly connected to a male sleeve, the outer surface of the female head is fixedly connected to a female sleeve, the outer surface of the male sleeve is provided with two limit grooves, the inner bottom walls of the two limit grooves are fixedly connected to a plurality of limit blocks arranged at equal distances, and one side surface of each of the limit blocks is set as an arc surface;

[0007] A connecting ring is fixedly connected to the outer surface of the left end of the female sleeve, and two connecting grooves are arranged on the inner wall of the connecting ring. A clamping plate is arranged inside the two connecting grooves, and a clamping column is arranged on the side of the left ends of the two clamping plates close to each other.

[0008] Through the above scheme, by setting the limit block and the clamping column, the purpose of the clamping column being squeezed and flipped by the limit block can be achieved when the male head is inserted into the female head. When the connection is completed, the clamping column cooperates with the limit block to limit the male head to prevent it from falling off or loosening. At the same time, by setting the double pressing plates inside the connecting ring, accidental collision with the pressing plates can be effectively avoided, thereby improving its stability during connection.

[0009] Furthermore, a blocking ring is fixedly connected to the outer surface of the male sleeve.

[0010] Through the above solution, by setting the blocking ring, the purpose of blocking the male head can be achieved, avoiding damage to the male head due to over-fitting.

[0011] Furthermore, two symmetrically arranged guide rods are fixedly connected to the right side of the blocking ring, and two guide holes are provided on the left side of the connecting ring.

[0012] Through the above scheme, by setting the guide rod and the guide hole, a guiding effect can be provided for the insertion of the male head, so that the sliding connection between the clamping column and the limiting groove is facilitated.

[0013] Furthermore, a reset shaft is rotatably connected between the front and rear inner side walls of the two connecting grooves, and each of the clamping plates is fixedly connected to the reset shaft adjacent to it.

[0014] Through the above solution and the setting of the reset shaft, it is possible to achieve the purpose of driving the left end of the clamping plate to flip upward when the clamping column is squeezed.

[0015] Furthermore, the right sides of the two clamping plates are fixedly connected with pressing plates.

[0016] Through the above solution and the setting of the pressing plate, it is convenient for the user to release the limit.

[0017] Furthermore, torsion springs are installed on the front and rear side surfaces of the two clamping plates, and the other ends of the two torsion springs are fixedly connected to the inner walls of the connecting grooves adjacent thereto.

[0018] Through the above solution and the provision of the torsion spring, the purpose of resetting the clamping plate can be achieved.

[0019] Furthermore, the ends of the two clamping posts that are close to each other are both rounded.

[0020] According to the above solution, by providing a rounded corner at one end of the clamping column, the smoothness when contacting with the limit block can be improved.

[0021] Furthermore, the outer surface of the connecting ring is knurled.

[0022] According to the above solution, by providing knurling on the outer surface of the connecting ring, it is possible to prevent the user from slipping when plugging in.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This coaxial cable connector, through the provision of a limit block and a clamping column, can achieve the purpose of the clamping column being squeezed and flipped by the limit block when the male head is inserted into the female head. When the connection is completed, the clamping column cooperates with the limit block to limit the male head to prevent it from falling off or loosening. At the same time, the arrangement of the double pressing plates inside the connecting ring can effectively avoid accidental contact with the pressing plates, thereby improving its stability during connection.
