the working principle of the invention;

when the coaxial cable is connected, firstly, stripping the part to be connected, and sleeving the external coating 100 on the cable;

then, the central conductor stripped is inserted into the central conductor connector 202 on the side, and at the same time, the slider 2003 is moved along the guide rail 2002, so that the two pressing parts 2001 of the cable to be connected move back to back, a space is left between the pressing parts 2001 and the lead parts 2000, so that the meshed conductor stripped can be inserted between the pressing parts 2001 and the lead parts 2000, then the first shell 101 and the second shell 104 are relatively pushed, the fixing claw 103 on the first shell 101 is inserted into the interlayer of the second shell 104, then under the action of the elastic part 1032 and the spring 1031, the fixing claw 103 passes through the limiting block 1041 to be clamped by the limiting block 1041, and at the moment, the first shell 101 and the second shell 104 are butted, meanwhile, the lead mechanisms 20 on the two sides are butted, the pressing parts 2001 are tightly fitted with the lead parts 2000, the meshed conductor with the limiting column is also limited, and the central cutter body is also limited, so that the connection of the coaxial cable is realized;

when the connected coaxial cable needs to be detached, the first shell 101 and the second shell 104 are pulled forcefully to drive the elastic expansion piece 1043 to move in the direction of the first shell 101 under the stress, the accommodating groove 1042 is left, then reverse force is applied to the first shell 101 and the second shell 104, the limiting block 1041 moves in the direction of the first shell 101 under the action of the fixing claw 103 to enter the accommodating groove 1042 and compress the elastic expansion piece 1043, (and the baffle 1044 supports the elastic expansion piece 1044 in the horizontal direction at the moment, so that the limiting block 1041 cannot be ejected from the horizontal direction), the limiting block 1041 cannot clamp the fixing claw 103, the first shell 101 and the second shell 104 can be separated from each other, then the elastic expansion piece 1043 resets, and the limiting block 1041 is extruded for later use. At the same time, the pressure of the pressing member 2001 and the lead member 2000 is removed, so that the mesh conductor can be pulled out from the two members, and finally, the mesh conductor can be pulled out from the central conductor connector 202, thereby easily completing the separation of the two members.
