Preferably, the height of described fixed cover is 1/5 ~ 1/3 of described pin second stage height.
Preferably, described pin second stage is provided with on one end of described body contact the abutment sleeve welded on the housing.
Preferably, described abutment sleeve is several sleeve composition, comprise weld with described fixed cover with the first sleeve of described case weld the second sleeve, be arranged on intermediate sleeve between described first sleeve and described second sleeve, described intermediate sleeve is fastened on described first sleeve and described second sleeve respectively.
Preferably, several described intermediate sleeve is provided with between described first sleeve and described second sleeve.
Preferably, the first sleeve ends described first sleeve welded with described fixed cover and described fixed cover arc transition.
The utility model has the advantage of: by arranging location dimples on the end of pin and welding circuit board, location dimples is utilized to realize the accurate location of pin and circuit board, then built-up welding solder in location dimples, realize pin and circuit board full weld, then fixed cover is set on the pin of location dimples position, realizes pin and be connected with the reliable of circuit board.
The end of pin and body contact arranges the abutment sleeve with case weld, and abutment sleeve weld with fixed cover, thus realizes housing and form one with pin and circuit and be connected reliable entirety, meets the normal work under complex working condition.
Accompanying drawing explanation
