Description
Technical field
The utility model belongs to microwave test field, particularly a kind of tab members DISCRETE ELASTIC SUPPORTS contact method test fixture.
Background technology
Along with system proposes more and more higher requirement to microwave components lightness, miniaturization, microwave components is encapsulated to three-dimension packaging future development by original two dimension just gradually, thus effectively utilize the space of vertical direction, nonetheless can be, the road of the miniaturization of microwave components still faces big challenge, such as the volume of the device such as connector, circulator own is large, and the assembly space greatly occupying assembly limits the further miniaturization of assembly.Adopt the external mode of connector effectively to solve the problem, such chip microwave components arises at the historic moment.And the connected mode of external connector and tab members just becomes the key issue needing to solve.
The interface shape that tab members externally provides is the point-like metal pad of plane, if adopt and micro-rectangular connector drawn the mode that pin is welded direct to assembly pad, not only welding quality is difficult to ensure, and this rigidly connected long-term reliability is also difficult to ensure, also has the risk of damage pad in rework process; Another common connected mode uses hair button to replace micro-rectangular connector, the elasticity utilizing the elasticity of hair button itself to realize between aerial lug with tab members interface point-like metal pad is connected, but easily by loose for hair button pressure, also there is safe hidden danger simultaneously, because excessive being easy to of hair button moment soft point cantact crimp force destroys tab members circuit substrate, and Long-Time Service is easy to wear causes loose contact or short circuit phenomenon.
Utility model content
For the deficiencies in the prior art, the utility model discloses a kind of tab members DISCRETE ELASTIC SUPPORTS contact method test fixture.
The technical solution of the utility model is as follows:
A kind of tab members DISCRETE ELASTIC SUPPORTS contact method test fixture, comprise tab members, described tab members is provided with point-like pad, the bottom surface of described point-like pad is provided with multiple pad; Also comprise first test splice and the second test splice that can fasten up and down; Described first test splice is fixed with the first limited block, and described tab members, near the first limited block, is fixed on the first test splice; Described second test splice is fixed with micro-rectangular connector, is provided with multiple sleeve pipe in described micro-rectangular connector, in sleeve pipe, is fixed with spring loaded contact probe; Also comprise the second limited block, described second limited block is provided with multiple circular hole running through its upper and lower surface; The quantity of the pad on described point-like pad, the circular hole on the second limited block and spring loaded contact probe and position all one_to_one corresponding; When the first test splice and the second test splice are fastened up and down, spring loaded contact probe, through the circular hole on the second limited block, contacts with the pad on point-like pad.
Advantageous Effects of the present utility model is:
The utility model compact in design, applied widely, practical and reliability is high.
The utility model adopts aluminum alloy materials as test splice, contact probe DISCRETE ELASTIC SUPPORTS contact method connecting test device then adopts the good probe of elasticity, both ensure that the accuracy be connected with tab members, also ensure that the security of tab members circuit substrate, longer serviceable life simultaneously, further increase proving installation long-term reliability.
