Description
Technical field
This utility model relates to a kind of piezoelectricity unit ultra-thin lug plate of assembly and thin footpath metal wire resistance spot-welded structures, particularly relates to a kind of this class formation being applied in airborne high temperature, broadband piezoelectric formula vibrating sensor the transmission of piezoelectricity unit assembly alternation charge signal.
Background technology
Piezoelectricity unit assembly assembling Structural Development is carried out under the model task of certain supporting piezoelectric vibration pickup of novel aero-engine is drawn, consider that this piezoelectric vibration pickup needs the performance requirement run sustainedly and stably under high temperature (485 DEG C) with wideband (being not less than 2.5kHz) operating mode, adopting tradition scolding tin and tape insulation skin lead-in wire Welding Structure cannot meet this requirement, technology difficulty is very huge.
Airborne piezoelectric vibration pickup is used for measuring engine luggine, when being fixed in mounting seat, the vibration that sensor outer housing impression is identical with mounting seat, such Internal moving mass will produce size and be proportional to the alternation inertia force effect in opposite direction of acceleration of vibration, direction and acceleration of vibration on the piezoelectric element. Direct piezoelectric effect due to piezoelectric element, two electrode surfaces just produce the quantity of electric charge and is proportional to the alternation electric charge of acceleration, when frequency of vibration is far below the natural frequency of sensor, the output charge amount of sensor is directly proportional to active force, namely being directly proportional to the acceleration of mounting seat, namely sensor measures vibration according to this principle.
Piezoelectricity unit assembly lug plate lead-in wire Welding Structure, transmits medium as wideband alternating charge signal, it is desirable to structure welding is reliable, additional mass is little, reliably carries out resonance free point in signal transmission, operating frequency range under the high temperature conditions.
Traditional designs for welding structure is because using scolding tin or tape insulation protection skin, and maximum temperature can only achieve 300 DEG C. What use multi cord and thin lug plate welds easy generating section filament welding breaking or rosin joint, and is mutually wound around owing to welding good filament with other and cannot check. Carefully circle lead-in wire and the direct welded structure of thin lug plate is used easily to produce the fault around solder joint by thin lug plate burn-through, or at thin circle lead solder-joint root because corrode produces constriction, the precision of reduction pin configuration intensity, reliability and signal transmission.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the resistance spot welding structure proposing a kind of piezoelectricity unit assembly lug plate, solves the problem that in piezoelectricity unit assembly, ultra-thin lug plate is connected with ultra-fine lead-in wire high-performance.
The purpose of this utility model, to be achieved by the following technical programs: the resistance spot welding structure of piezoelectricity unit assembly lug plate, relate to lug plate and lead-in wire, described lug plate is the ultra-thin lug plate of thickness 0.05mm, described lead-in wire is the thin footpath metal wire of �� 0.2mm, it is characterized in that: described resistance spot welding structure is provided with rustless steel switching piece between lug plate and lead-in wire, and the resistance spot welding respectively of lug plate and lead-in wire is on rustless steel switching piece.
Further, described rustless steel switching piece is the stainless steel band that 0.06mm is thick, wide for 1mm, and is set to two panels stainless steel band in the wire outlet part of piezoelectricity unit assembly and sandwiches lead-in wire.
Further, described lug plate and rustless steel switching piece are set to the Welding Structure of ladder offset.
Remarkable result after technical solutions of the utility model application implementation is: achieve the not damaged welding of thin slice fine rule, and combination quality is light, improves dynamic response frequency scope; Adopting high resistivity rustless steel switching piece to be avoided that the problem of generating section welding breaking or rosin joint, produce stress and concentrate flanging, this resistance spot welding structure also improves the Applicable temperature of sensor simultaneously.

Detailed description of the invention
Hereinafter just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are more readily understood, grasp.
This utility model is in view of existing defect technically existing in superfine welding, and innovation proposes the resistance spot welding structure of a kind of piezoelectricity unit assembly lug plate. As depicted in figs. 1 and 2, this resistance spot welding structure relates to two components A, B docking mutually in piezoelectric vibration pickup, it is specifically related to wherein respective had lug plate and lead-in wire, from concrete details architectural feature, this lug plate is the ultra-thin lug plate of thickness 0.05mm, and the thin footpath metal wire for �� 0.2mm that goes between, to well imagine, the technology difficulty of this resistance spot welding structure C is big. And this resistance spot welding structure that this creation is developed as it is shown in figure 1, be provided with rustless steel switching piece 3 between lug plate 1 and lead-in wire 2, lug plate 1 is welded on rustless steel switching piece 3 with lead-in wire 2 resistance 4 respectively.
For meeting the specification of lug plate and lead-in wire, this rustless steel switching piece 3 selects the stainless steel band that 0.06mm is thick, wide for 1mm, and is set to two panels stainless steel band in the wire outlet part of piezoelectricity unit assembly and sandwiches lead-in wire. And illustrate this lug plate and rustless steel switching piece as seen and be set to the Welding Structure of ladder offset.
It should be understood that piezoelectricity unit assembly lug plate is designed to the foil of 0.05mm thickness 1mm width overall dimensions, material is nickel-base alloy band. And switching piece is designed to the stainless steel band that 0.06mm thickness 1mm is wide. Lead-in wire be �� 0.2mm nickel-base alloy line. It is consider that this alloy has higher ductility that lug plate and lead material are all nickel-base alloy, and switching piece material is set to stainless steel substrates, has higher resistivity, it is prevented that and adhesion close with point of resistance soldering tip resistivity produces folding line damage. Wire outlet part adopts two panels stainless steel band folder nickel filament structure, it is prevented that constriction loses limit with welding. Staged Welding Structure, it is prevented that lug plate and stainless steel band are arranged in homonymy and produce to touch friction and cause electrical noise, can increase the bending degree of freedom of stainless steel band simultaneously, improve assembly manipulation. Comparing conventional wire Welding Structure, this structure also has assembles the advantages such as simple and reliable, with low cost.
Remarkable result general introduction after technical solutions of the utility model application implementation: it achieves the not damaged welding of thin slice fine rule, and combination quality is light, improves dynamic response frequency scope; Adopting high resistivity rustless steel switching piece to be avoided that the problem of generating section welding breaking or rosin joint, produce stress and concentrate flanging, this resistance spot welding structure also improves the Applicable temperature of sensor simultaneously.
In addition to the implementation, this utility model can also have other embodiment. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within this utility model scope required for protection.
