Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a cable joint sealing insulation structure. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each line segment must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called the intermediate joint, and the cable joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention.

[0003] When two existing cable joints are butt-jointed, they are mostly connected using threaded butt joints. Although threaded butt joints can have a certain degree of stability, after long-term use, such threaded butt joints are prone to loosening and thread slippage, resulting in a gap between the two butt joints, which will affect the sealing of the two butt joints and thus affect the normal use of the cable. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a cable joint sealing and insulating structure, which can solve the problem that threaded butt joints are prone to loosening and slipping.

[0006] Preferably, the fixing assembly comprises a limiting slider, the outer surface of which is slidably connected to the inner wall of the limiting slide groove, one end of the limiting slider is provided with a groove, and a ball is rotatably connected inside the groove.

[0007] Preferably, one end of the limiting sliding block is fixedly connected to a pull rod, the outer surface of the pull rod is provided with a pressure spring, and the pressure spring is installed inside the limiting sliding groove.

[0008] Preferably, circular grooves are formed on the outer surfaces of the two pairs of joints, and the interior of the circular grooves is connected to the interior of the limiting sliding grooves.

[0009] Preferably, one end of the pull rod away from the limiting slider slides through the inside of the circular groove, and one end of the pull rod away from the limiting slider is fixedly connected with a pull ring.

[0010] Preferably, a thread is provided on the outer surface of the insulating sleeve near the first pair of joints, and a groove is provided at the thread on the outer surface of the insulating sleeve near the first pair of joints, and the inner wall of the groove is slidably connected to the outer surface of the ball.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The sealed insulating structure of the cable connector is connected by connecting the opposite ends of the two cables. Then, under the action of the pressure spring, the ball and part of the limit slider enter the interior of the slot, so that the second pair of connectors are fixed on the surface of the corresponding insulating sleeve, so that the second pair of connectors and the insulating sleeve are not easy to loosen and slip, thereby ensuring the sealing of the connection between the first pair of connectors and the second pair of connectors, further improving the practicality of the cable connector.
