Abstract
Description
Technical Field
[0001] The utility model relates to a conductive cable connection structure, in particular to a double-cone shrinkable wire clamping type conductive cable connector. Background Art
[0002] For example, the "External Conductive Cable Connector" with authorization announcement number CN214673003U has a technical solution including a connection method between a conductive wiring ear and a single conductive cable core and a connection method between a conductive wiring sleeve and two conductive cable cores.
[0003] The connection method between the conductive lug and the single conductive cable core is as follows:
[0004] 1. The conductive conical shrink sleeve is placed in the sleeve hole of the locking screw sleeve, the small head end of the conductive conical shrink sleeve is matched in the conical hole of the sleeve hole, and the large head end of the conductive conical shrink sleeve is in the internal thread hole of the sleeve hole.
[0005] 2. The core of the conductive cable passes through the tapered hole of the locking screw sleeve and the sleeve hole of the conductive tapered shrink sleeve, then passes through the internal thread hole of the locking screw sleeve and is placed in the sleeve hole at the head end of the conductive wiring ear sleeve.
[0006] 3. The internal thread hole of the locking screw sleeve is screwed into the external thread of the conductive wiring ear sleeve. During the screwing process of the locking screw sleeve, the locking screw sleeve first axially stops the conductive conical shrink sleeve on the sleeve end of the conductive wiring ear, and then the locking screw sleeve moves axially on the conductive conical shrink sleeve. During the movement, the locking screw sleeve continuously radially shrinks the conductive conical shrink sleeve to clamp the conductive cable core.
[0007] The shortcomings are:
[0008] 1. The conductive cable core is clamped in the locking screw sleeve, while the conductive cable core in the conductive wiring ear is in a relaxed state. The sleeve end of the conductive wiring ear is pressed against the conductive conical shrink sleeve, the conductive contact surface is small, and the conductive performance is insufficient.
[0009] 2. If the locking screw sleeve becomes loose due to an accident, the tightening force between the conductive terminal ear and the conductive conical shrink sleeve will be reduced and become loose, resulting in poor contact between the conductive conical shrink sleeve and the conductive cable core.
