The utility model adopts following technical scheme to realize: a kind of insulation spacer of three lead-in wire quartz-crystal resonators, comprise a rectangle insulating substrate, this rectangle insulating substrate central horizontal position is provided with some lead hole successively, this insulating substrate comprises front and back, the front of this insulating substrate is provided with some lead-in wire grooves, these some lead-in wire groove one ends connect this some lead hole respectively, and the other end all extends to this insulating substrate edge; The back side of this insulating substrate is provided with the right angle trigonometry cylinder of two vertical these insulating substrates.
This lead hole and this lead-in wire groove are three, and these three lead-in wire grooves are arranged in parallel.
Two ends two lead-in wires groove fluting direction of these three lead-in wire grooves is opposite with middle lead-in wire groove fluting direction.
This lead hole is truncated cone, and the end that its internal diameter is little leads in the positive of this rectangle insulating substrate and with this lead-in wire groove and links to each other, and the end that internal diameter is big leads in the back side of this rectangle insulating substrate.
This two right angle trigonometries cylinder is located at an end of the lead-in wire groove fluting direction of this centre respectively.
The insulation spacer of electric resistance welding mode three lead-in wire crystal resonators provided by the utility model, the design of employing simplification, do not have under the condition of image identification at automatic nest plate equipment, can adopt the mode that hangs feeding with the vibration feeding track by two right angle trigonometry cylinders that insulation spacer arranges, realize lead-in wire groove fluting face and the back side and the identification in the right direction of lead-in wire fluting, thereby accurately finish the assembling with three lead-in wire quartz-crystal resonators, and this insulation spacer can bear 30 minutes time under 300 ℃ high temperature.The utility model is simple in structure, the realization cost is lower.
