Title:

INSERTION STRUCTURE BETWEEN STATIC SPRING AND BOBBIN

Document Type and Number:

WIPO Patent Application WO/2018/095417

Kind Code:

A1

Abstract:

The present disclosure relates to an insertion structure between a static spring and a bobbin, comprising a static spring and a bobbin, wherein the static spring is inserted into the bobbin by using an inverted manner; the bobbin is provided with a slot, which an L-shaped sidewall and a convex wall enclose to form, while the static spring is provided with a convex portion, the convex portion of the static spring fitting into the slot; a first blocking wall is further provided in a protruding direction of a convex wall which extends horizontally, a second blocking wall is further connected between the first blocking wall and the L-shaped sidewall, and the convex portion of the static spring is mounted on the second blocking wall such that tiny fragments, which are formed when the convex portion of the static spring is mounted into the slot, fall into a cavity which the first blocking wall, the second blocking wall, the L-shaped sidewall, and the convex wall enclose to form. The structure of the embodiments of the present invention allows produced tiny fragments to be enclosed in a particular space instead of entering an inner portion of a relay/circuit breaker, thereby ensuring the normal use of the relay/circuit breaker.
