Abstract
The utility model discloses a stationary fixture for PCB vibration and impact test. The stationary fixture comprises a bottom plate and a concave pressure bar, wherein the bottom plate is provided with a PCB gold finger supporting block and a PCB screw hole supporting pillar; and the concave pressure bar is provided with a groove. The width of the groove adapts to the thickness of the bottom plate, and two ends of the concave pressure bar are provided with fixed bolt holes. As the stationary fixture for PCB vibration and impact test adopts rigid connection, the force generated by testing equipment is totally transmitted to a test sample without buffering when a PCB is fixed on the testing equipment, thus leading to more reliable testing result and better repeatability.
Description
Technical field
The utility model relates to a kind of stationary fixture, the stationary fixture of particularly a kind of pcb board vibration and impulse test.
Background technology
Pcb board is the important electron parts, is the supporter of electronic devices and components, is the supplier that electronic devices and components are electrically connected, because it is to adopt electron printing to make, so be called as " printing " circuit board.In the production run of pcb board,, need carry out various detection tests to pcb board in order to verify the quality of pcb board.When pcb board being vibrated, pcb board need be fixed on corresponding vibration or the impact device with impulse test.The stationary fixture of pcb board generally adopts aluminium sheet or template to support at present, and the rigidity of these stationary fixtures is relatively poor, and response is subjected to the influence of installation personnel installation level bigger in its test.Having specimen generally to stick on aluminium sheet or the plank with the 3M adhesive tape again tests, because adhesive tape has certain buffer action, the vibration force or the impulsive force that make specimen like this and suffered are offset, and adopt this stationary fixture to have relatively poor repeatability, influence the test effect of specimen.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of pcb board vibration of simple in structure, good rigidly and the stationary fixture of impulse test.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The stationary fixture of a kind of pcb board vibration and impulse test, it comprises: a base plate, described base plate are provided with pcb board golden finger back-up block and pcb board screw hole support column; One spill press strip, described spill press strip is provided with groove, and the width of described groove and the thickness of described base plate adapt, and the two ends of described spill press strip are provided with fixed bolt hole.
Preferably, comprise that also one supports " L " type back-up block of described base plate.
Preferably, described base plate is an aluminium sheet.
Preferably, it also comprises and described base plate can be fixed on the testing apparatus ceiling molding.
Technique scheme has following beneficial effect: the stationary fixture of this pcb board vibration and impulse test in use, at first pcb board is fixed on the base plate, by the fixing golden finger position of pcb board of pcb board golden finger back-up block, by the fixing screw hole position of pcb board of pcb board screw hole support column.Then base plate is placed vertically on testing apparatus, the top of base plate is inserted in the groove of spill press strip, passes fixed bolt hole by bolt then the spill press strip is fixed on the testing apparatus, and base plate also just is fixed on the testing apparatus together with pcb board like this.This pcb board vibration is rigidly connected with the stationary fixture employing of impulse test, like this when pcb board is fixed on the testing apparatus, the power that produces on the testing apparatus makes non-cushioned complete passing to on specimen test result more reliable, and has better repeatability.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the vertical view of the utility model embodiment.
Fig. 3 is the structural representation of the utility model spill press strip.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, this pcb board vibration comprises a base plate 1 and a spill press strip 2 with the stationary fixture of impulse test, and base plate 1 is provided with pcb board golden finger back-up block 11 and pcb board screw hole support column 12.Spill press strip 2 is provided with groove 21 (as shown in Figure 3), and the thickness of the width of groove 21 and base plate 1 adapts, and the two ends of spill press strip 2 are provided with fixed bolt hole, and wherein base plate 1 is an aluminium sheet.This pcb board vibration also comprises " L " type back-up block of supporting baseplate 1 and base plate 1 can be fixed on the testing apparatus ceiling molding with the stationary fixture of impulse test
To pcb board impact of direction all around or vibration test the time, at first pcb board is fixed on the base plate 1, by the fixing golden finger position of pcb board of pcb board golden finger back-up block 11, by the fixing screw hole position of pcb board of pcb board screw hole support column 12.Base plate is placed vertically on testing apparatus 4 then, the top of base plate is inserted in the groove 21 of spill press strip 2, pass fixed bolt hole by bolt 3 then spill press strip 2 is fixed on the testing apparatus 4, base plate 1 also just is fixed on the testing apparatus together with pcb board like this.
On to pcb board, impact or during vibration test, only need plate upper surface is upwards lain on the testing apparatus 4, with press strip base plate is compressed then and get final product.Below pcb board, impacting or during vibration test, only needing upwards with the base plate lower surface, for preventing to damage by pressure pcb board, under base plate, place " L " type back-up block base plate is supported, with press strip base plate is compressed then and get final product.
This pcb board vibration is rigidly connected with the stationary fixture employing of impulse test, like this when pcb board is fixed on the testing apparatus, the power that produces on the testing apparatus makes non-cushioned complete passing to on specimen test result more reliable, and has better repeatability.
More than the stationary fixture of a kind of pcb board vibration that the utility model embodiment is provided and impulse test be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
