Abstract
Disclosed is a bushing terminal of a vacuum circuit breaker used for interrupting current, which includes: a terminal body having a cylinder that can be inserted into the interior of a contactor and annular protrusions formed to be protrude from an outer circumferential surface of the cylinder; and a flange having an insertion hole through which the cylinder is inserted, wherein the annular protrusions are plastic-deformed so as to be fixed to the insertion hole of the flange.
Claims14
A bushing terminal of a vacuum circuit breaker, the bushing terminal comprising:
- a terminal body having a cylinder that can be inserted into the interior of a contactor and annular protrusions formed to be protrude from an outer circumferential surface of the cylinder;
- and
- a flange having an insertion hole through which the cylinder is inserted, wherein the annular protrusions are plastic-deformed so as to be fixed to the insertion hole of the flange.
A bushing terminal of a vacuum circuit breaker, the bushing terminal comprising:
- a terminal body having a coupling portion formed at one end portion thereof and a cylinder inserted into the interior of a contactor;
- and
- a flange having an insertion hole to which the coupling portion is inserted,
- wherein the coupling portion of the terminal body is plastic-deformed so as to be fixed to the insertion hole.
A method for fabricating a bushing terminal of a vacuum circuit breaker, the method comprising:
- fabricating a terminal body including a cylinder with a plastic-deformation region on an outer circumference thereof;
- fabricating a flange having an insertion hole through which the plastic-deformation region of the cylinder is to be inserted;
- inserting the plastic-deformation region of the cylinder into the insertion hole;
- and
- pressing the plastic-deformation region to plastically deform the plastic-deformation region.
