Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing heads, in particular to a sealing structure of a cable fixing head. Background Art

[0002] Cable waterproof connectors are commonly used in power systems. They are primarily used in outdoor products, medium-to-large remote-controlled machinery, and equipment where the main unit is located outdoors but the control system is not located on the main unit. For example, cable waterproof connectors are used in chemical plants, power plants, power supply bureaus, telecommunication network base stations, and highly automated factories.

[0003] Based on the above, the inventors have discovered the following problems: the sealing materials used for single-end sealing, such as rubber sealing rings, will age over time. When exposed to the external environment for a long time, the rubber will be affected by factors such as ultraviolet rays, temperature changes, and chemicals, resulting in reduced elasticity, increased hardness, and cracks. Once the sealing ring ages, its fit with the cable sheath will deteriorate, thereby reducing the sealing performance.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a sealing structure of a cable fixing head is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1 - Figure 5The bottom end of the limiting ring 1007 and the upper end surface of the locking ring 1005 are both embedded with a sealing ring 1013. The sealing ring 1013 and the sealing sleeve 1002 are both made of rubber.

By providing anti-slip textures on the outer sides of the first locking cap 1006 and the second locking cap 1003, it is convenient for users to rotate them. Specifically, the working principle of the sealing structure of this cable fixing head is as follows: when in use, the user inserts one end of the connector 1001 into the mounting hole of the device, so that the limiting ring 1007 rests on the outside of the hole, and then rotates the locking ring 1005 so that it rests on the inside of the mounting hole, and cooperates with the limiting ring 1007 to fix the connector 1001 on the mounting hole. After the installation is completed, the user puts the sealing sleeve 1002 on the outside of one end of the cable, and then inserts one end of the cable into the interior of the connector 1001 through the second locking cap 1003 and passes through it. Then, the user threads the second locking cap 1003 and the first locking cap 1006 with the second thread 1012 and the first thread 1004 respectively. The user then rotates the wheel 2002 to drive the screw 2003 to rotate. When the screw 2003 rotates, it drives the piston 2004 to move, and injects the air inside the inflation box 2001 into the interior of the airbag 1011 through the air inlet 2005. After the airbag 1011 is inflated, the gap between the sealing sleeve 1002 and the interior of the connector 1001 is squeezed, thereby improving the sealing effect inside the connector 1001.
