Description
Technical field
Resistance device technical field is the utility model is related to, is specially a kind of varistor that can steadily place.
Background technology
At present, known varistor construction is mixed by the added lot of trace metal oxide of primary raw material of zinc oxide
Close sintering to form, in the plug-in type varistor using CP lines as pin, formed with silicone insulation encapsulation.Because of common pressure-sensitive electricity
Resistance or capacitance are plug-in types, if desired when connecting varistor or capacitance on pcb board, it is necessary to drill on pcb board, so
Not only processing technology is more complicated, and since drilling can cause some pcb boards to be scrapped, and then the production of pcb board can be caused to add
The efficiency of work reduces, and can also lift the scrappage of pcb board；And some pcb board requirements being used in LED light cannot drill, this
The varistor or capacitance of sample plug-in type can not be just used on the pcb board in LED light, therefore are just needed varistor or electricity
Appearance is directly welded on pcb board.But due to most of varistor or capacitance be using CP wire as electronic pins,
One end of the tinning steel-in-copper wire pin of varistor or capacitance is scolding tin resistance chip or capacitance on varistor or capacitance
On chip, so as to cause the combination scolding tin position of resistance chip or electric capacity chip and CP wire raised, by pressure-sensitive electricity
Resistance or capacitance are placed on when being welded on pcb board, and varistor or capacitance can not be smoothly placed in the plane of pcb board, led
The easy mobile pad deviateed on pcb board when causing the pin welding of varistor or capacitance, thus influence welding quality and
Welding efficiency.
Utility model content
The utility model provides one kind and can be stably placed on circuit board, meets the circuit board need that can not process jack
Ask, convenient welding, of low cost, simple production process, the varistor that can steadily place of production easy to process.
The utility model can be achieved through the following technical solutions：
A kind of varistor that can steadily place, including resistance chip, the first welding pin and the second welding pin, it is described
Resistance chip exterior is enclosed with insulating outer layer, and one end of first welding pin is electrically connected with the one side of resistance chip, described
One end of second welding pin is electrically connected with the another side of resistance chip, what the resistance chip was electrically connected with the first welding pin
Support protrusion is simultaneously equipped with, the other end of first welding pin forms the first flat foot by bending, and second welding is drawn
The second flat foot that the other end of foot is formed by bending, the first flat foot and the second flat foot are arranged in parallel with resistance chip, the
The peak three of the bottom surface of one flat foot, the bottom surface of the second flat foot and support protrusion is in same level.The utility model can
The varistor steadily placed, mainly sets support protrusion in the one side of varistor, then by the first welding pin and
The outer end of second welding pin is bent into the first flat foot and the second flat foot, make the bottom surface of the first flat foot, the bottom surface of the second flat foot and
The peak three of support protrusion is in same level, when so varistor is put on circuit boards, the bottom surface of the first flat foot,
The bottom surface of second flat foot and the peak of support protrusion contact support with circuit board surface, varistor is smoothly placed
On circuit boards；And since varistor can be kept flat on circuit boards, the first flat foot and the second flat foot of varistor can
Directly with circuit board surface contact weld, without resistance jack is processed on circuit boards, to meet the circuit that can not process jack
