Description
Technical field
The utility model relates to a kind of electronic devices and components, particularly belongs to a kind of Miniature Quartz with ground lead.
Background technology
Crystal resonator in electron trade, just towards the future development of miniaturization, microminiaturization, requires also more and more higher to its stability and interference free performance simultaneously at present.But, in the horizontal situation of existing processing technology, increasing ground connection is difficult to realize for miniaturization, microminiaturized crystal resonator, and need multiple tracks procedure of processing, drop into multiple devices and carry out processing, also brought product fraction defective compared with problems such as ground lead high and that cause because of failure welding come off simultaneously.Therefore for microminiature crystal resonator, be not all provided with at present earthing device, therefore affected to a certain extent the stability of its service behaviour.
Utility model content
The purpose of this utility model is to provide a kind of Miniature Quartz with ground lead, to reach the object of being convenient to realize the grounding connection of microminiature crystal resonator and then improving its stability and anti-interference.
The Miniature Quartz with ground lead provided by the utility model, comprise substrate, insulator, lead-in wire, wafer and shell, insulator is placed in on-chip insulator placement hole, lead-in wire is through the wire perforation on insulator, lead-in wire ailhead and wafer connect, and substrate top is coated with shell, it is characterized in that, substrate body is also provided with ground lead, corresponding with earth connection or the zero line of the external circuit board.
The Miniature Quartz with ground lead provided by the utility model, its total length is between 2.0 millimeters-7.1 millimeters, and overall width is between 1.0 millimeters-4.2 millimeters.
A kind of Miniature Quartz with ground lead provided by the utility model, owing to being provided with ground lead in substrate body, when carrying out welding circuit board, can directly be grounded, changed the no ground situation of microminiature crystal resonator, improve stability and the interference free performance of crystal resonator, and there is good effect simple in structure, cost of manufacture is low.
