Description
Technical field
The utility model relates to a kind of electronic devices and components, and more particularly, it relates to a kind of semiconductor diode.
Background technology
In current electronic devices and components, semiconductor diode is as the most frequently used accessory of electronic devices and components, because semiconductor diode has rectification function, therefore, be widely used on various electronic devices and components, current existing diode kind is a lot, current existing diode, mainly comprises chip and is coated on the shell of chip exterior, be provided with PN junction in chip, shell is injection molded by modified epoxy, is provided with the pin be connected with chip at the two ends of shell.
When diode is installed on circuit board, first the pin of diode is needed to carry out bending according to installation, subsequently again by corresponding welding hole on the pin of diode insertion circuit board, finally by welding wire, the pin of diode is welded and fixed on circuit boards, because pin is welded and fixed setting on circuit boards, after diode is damaged, because pin and diode are wholely set, therefore want to pull down diode, pin will be pulled up from circuit board, because pin is welded on circuit boards, therefore, pin is wanted to disassemble just very inconvenient from circuit board, in addition, the chip that what diode was damaged is mostly in housing, pin scarcely can be damaged, therefore, pin also need not be disassembled and change.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of semiconductor diode, can realize the replacing of the semiconductor diode damaged very easily.
For achieving the above object, the utility model provides following technical scheme: a kind of semiconductor diode, comprise chip and be coated on the shell of chip exterior, described shell two ends are equipped with chute, described chute diapire is provided with the fixed contact be connected with chip, in described chute, slippage is connected with pin, and described pin can abut with fixed contact, is provided with the positioning element of positioning pins in described chute.
Preferably, in chute, slippage is connected with slide block, and described pin is fixedly installed on slide block, and described positioning element comprises the shell fragment tilting to be fixedly installed on chute wall.
Preferably, described pin adopts with slide block and is threaded.
Preferably, described chute wall is provided with guide rail along track length direction, described slide block is provided with the groove coordinated with guide rail.
Preferably, described rail end is provided with chamfering structure.
By adopting technique scheme, after by pin bending welding on circuit boards, after the chip in diode is damaged, only need the locking removing positioning element, can along chute, housing is separated with pin, realize the dismounting of housing, install new chip more subsequently, the fixing of pin and housing can be realized by positioning element, do not need pin to be disassembled the replacing that yet can realize chip, achieve the replacing of the diode of damage very easily.
