Background technique
In the slow test of radome or antenna house, the strain that measurement testpieces occurs is almost essential item
Mesh needs to connect with strain line, passes through strain line and strain acquirement after foil gauge is cured on radome by adhesive
System is connected, and the strain of testpieces could be acquired in test.The quality that foil gauge is connect with strain line is directly related to strain
The acquisition of data, therefore must be carefully conscientious when connecting strain line, it is ensured that quality of connection, therefore the company of foil gauge and strain line
It is highly important for connecing.
Summary of the invention
The purpose of the present invention: a kind of wiring construction that can effectively ensure that strain line Yu foil gauge quality of connection is provided.
Technical solution of the present invention: a kind of strain measurement foil gauge wiring construction, it is characterized in that: the structure includes
Bottom plate 1, pressure head 2, compression leg 3, spring 4 and shell 5, snap-gauge 9
The lower end of compression leg 3 is fixed with pressure head 2, and the upper surface of bottom plate 1 is embedded with sheet metal 6, and sheet metal 6 is being located at compression leg 3 just
Lower section, spring 4 are sleeved on compression leg 3, and one end is limited on shell 5, and one end is limited on compression leg 3；
It is machined with through-hole 8 on shell 5, elastic fulcrum bar 7 is provided on compression leg 3, the end of elastic fulcrum bar 7 is adjacent in shell 5
On inner surface, the through-hole on shell 5 is located on 7 end motion path of elastic fulcrum bar.
Preferably, the wiring construction further includes two compression legs being fixedly connected 3, every push down 3 under be respectively fixed with
One mutually independent pressure head 2, the lower corresponding mutual disconnected sheet metal of each pressure head 2.
Preferably, the wiring construction further includes two mutually independent compression legs 3, every push down 3 under be respectively fixed with
One mutually independent pressure head 2, the lower corresponding same section of sheet metal of two pressure heads 2.
Beneficial effects of the present invention: radome slow test foil gauge wiring construction of the invention can make the company of wiring
Quality advance is connect, there is the spring 4 in wiring construction larger elastic force connected wiring can be made firmly to be pressed on sheet metal 6
On, sheet metal 6 is copper sheet, is had good conductive property, and guarantees the route well conducting connected.Radome static(al) of the invention

Detailed description of the invention
Fig. 1 is a kind of strain measurement foil gauge wiring construction outside drawing；
A kind of strain measurement of Fig. 2 is formed with foil gauge wiring construction to be schemed.
Specific embodiment
Radome slow test is usually resistance strain gage with foil gauge, is mainly made of sensitive grid and substrate, is used
When be strongly adhered on the measuring point of radome, deform when radome stress during slow test, sensitive grid
Also so that its resistance is changed therewith deforming, then the variation of resistance is measured by strain gauge and is converted to strain value.?
During radome slow test strain measurement, need for two piece-root grafting lines of foil gauge to have connect with the wiring on strain gauge
Come, the present invention can realize efficient, the quick connection of foil gauge.
Radome slow test strain measurement is with foil gauge wiring construction by bottom plate 1, pressure head 2, compression leg 3, spring 4, shell
5, sheet metal 6, elastic fulcrum bar 7, through-hole 8 and snap-gauge 9 form.The pressure head 2 that is mainly characterized by of wiring construction is plugged on compression leg 3,
3 upper end of compression leg is connected together, and elastic fulcrum bar 7 is provided on compression leg 3, and the end of elastic fulcrum bar 7 is adjacent to the table in shell 5
On face, 4 sets of spring between compression leg 3 and snap-gauge 9, snap-gauge 9 can be fixed in shell 5, sheet metal 6 is installed on bottom plate 1, gold
Belong to the underface that piece 6 is located at compression leg 3, is provided with through-hole 8 on shell 5, compression leg 3 can slide in the through-hole 8 on 5 top of shell.It connects
Cable architecture in use, two piece-root grafting lines of foil gauge are inserted into respectively in two through-holes 8 of 5 lower part of shell first, will connect
Two piece-root grafting lines be inserted into two through-holes 8 of another side lower part of shell 5 respectively, then press two compression legs 3, elastic fulcrum bar 7 respectively
It is limited in the through-hole 8 of 5 top two sides of shell, spring 4 is in confined state at this time, and the elastic force of generation is by pressure head 2 and gold
The wiring belonged between piece 6 compresses, and forms conductive path by sheet metal 6, completes foil gauge wiring connection.Entire wiring construction
It can be bonded on radome cover by double-sided adhesive or foam glue strip.When needing to remove conducting wire, pinched simultaneously with hand same
Elastic fulcrum bar 7 on a compression leg 3, compression leg 3 are bounced by spring, and band dynamic head 2 rises, and are no longer pressed between pressure head 2 and sheet metal 6
Tightly, connected line can unlock connection.
