Through the line ball gasket, can increase and the crimping area between the hard wire, it is more reliable to compress tightly the hard wire.

Furthermore, the side surface of the line pressing gasket, which faces the main connecting sheet, is protruded with a limiting protrusion, so that the hard line is limited and prevented from being extruded out of the line pressing space, and the reliability of the line pressing is further improved.

In addition, the flexible wire compression joint section is of a sleeve body structure, so that the flexible wire can be wrapped inside, and the extrusion and fixation of the flexible wire can be realized more reliably.

Further, the sleeve body is a C-shaped sleeve, so that a larger deformation amount can be generated when the sleeve body is extruded, and the flexible wire can be more firmly pressed.
