Abstract
Disclosed is a surge protector tripping mechanism which comprises an elastic element and a chip. The tripping mechanism employs the elastic element as a conductor to replace an original spring, a support and a terminal strip and to be directly welded with electrodes on the chip; the E-shaped elastic element is provided with three groups of welding ends chosen according to the intensity of current; square holes are arranged on the elastic element; and the electrodes of the chip are inserted into the square holes of the elastic element when in welding. The tripping mechanism has the advantages of increasing welding contact surfaces, enhancing reliability, decreasing assembly procedures and improving working efficiency.
Description
Technical field
This utility model relates to a kind of surge protector that is applied to, and belongs to the low-voltage electrical apparatus field.
Background technology
In existing numerous surge protector; tripping mechanism is by spring; support; lug plate; chip is formed; chip and lug plate welding contact-making surface are little; this mechanism exists because complex structure; it is more that reliability of technology relates to factor; defective such as wayward; when running into abnormal conditions; be difficult for reliable fully the dropout; and the chip of this structure mainly is by several chip portfolios together, connects by an electrode slice, and the cross-sectional area of conductor at the electrode hole place on electrode slice is less; so can not be applied to the surge protector of big electric current, as 100KA; 120KA; 150KA etc.
Summary of the invention
The utility model is at the deficiency of existing various surge protector tripping mechanisms; design that a kind of grouping connects as conductor, chip, loaded current on each electrode just is its 1/3 by flexible member, surge protector tripping mechanism that can bearing great current.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of surge protector tripping mechanism is made up of flexible member and chip, this tripping mechanism by flexible member as conductor; substituted original spring, support, lug plate, directly with chip on electrode weld, this flexible member is the E type; 3 bond pads ends are arranged; select welding according to size of current, square hole is arranged on the flexible member, during welding chip electrode is inserted in the flexible member hole; increase the welding contact-making surface; increase reliability, reduced assembly process, improved operating efficiency.
The beneficial effects of the utility model are:
This surge protector tripping mechanism has increased chip electrode and flexible member welding contact-making surface, has increased reliability, has reduced assembly process, has improved operating efficiency.
