Background technology
Crystal oscillator (abbreviation crystal oscillator) kind is a lot, mostly is specialized factory and produces.Domestic production producer is few at present, and the crystal oscillator that electron trade is used mostly is import, therefore is worth expensive.At being worth expensive crystal oscillator, whether its quality satisfies product needed, need verify it.Many electronic products all will carry out vibration test, and can checking reliable and stable in transportation and production use.In working practice, the idle phenomenon of crystal oscillator after the product vibration test takes place in regular meeting.Product for complicated breaks down in case second-rate crystal oscillator is contained on the machine, and replacing is comparatively difficult.
At present, there be routine experiment chamber few of last scale in the enterprise that produces electronic product, and the product vibration table generally all is used for complete machine oscillation to be tested, and its anchor clamps all are to design voluntarily.General enterprise does not have the routine experiment chamber, and many tests all can only be carried out external coordination.One one carry out vibration test and will increase cost greatly, and external coordination producer also can not have suitable anchor clamps to use for enterprise.Independently will to carry out vibration test be very difficult to crystal oscillator, and reason is that it is very little, in light weight, do not have special-purpose anchor clamps to come clamping to operate, and has clamping device also can only clamping is several simultaneously to test.
At this problem, we are according to the size of shaking table, for save time, power saving, cost-saving, having designed can disposable vibration 30, safe and reliable crystal oscillator oscillation test fixture.
If but at present incompetent on market crystal oscillator is carried out the instrument of vibration experiment, and therefore can't before production, reject the fault crystal oscillator, also can't test it and can satisfy the product needed condition.
Summary of the invention
The present invention is intended to solve at present crystal oscillator is carried out vibration experiment very difficulty, low, the cost high-technology problem of vibration experiment efficient in batches, a kind of efficient height to be provided, once can to carry out tens of crystal oscillator vibration experiments, safe and reliable crystal oscillator oscillation test fixture.
The objective of the invention is to be achieved through the following technical solutions.
Crystal oscillator oscillation test fixture of the present invention is made of location-plate 1, pressing plate 2, backing plate 3 and web member, and tested crystal oscillator 4 is arranged between the location-plate 1 of being located at top and the backing plate 3 of being located at the bottom, and backing plate 3 belows are provided with pressing plate 2; Aforementioned location-plate 1, pressing plate 2, backing plate 3 are fixedly connected by the array web member, and every group of web member is made of screw 5 and nut 6, and screw 5 passes corresponding aperture on location-plate 1, pressing plate 2, the backing plate 3, is connected on location-plate 1 with nut 6; Location-plate 1 is provided with the perforate that matches with the crystal oscillator pin 7 of tested crystal oscillator 4.
Crystal oscillator oscillation test fixture of the present invention, wherein said tested crystal oscillator 4 is 30, be arranged between location-plate 1 and the backing plate 3 by horizontal 5, vertical 6 mode, every tested crystal oscillator 4 number of pins are 4, pass the corresponding aperture on the location-plate 1 respectively, the diameter in hole is than the big 0.2～0.4mm of leg diameter.
Crystal oscillator oscillation test fixture of the present invention, wherein said pressing plate 2 is a sheet metal, it is all identical with weight with location-plate 1 size.
Crystal oscillator oscillation test fixture of the present invention, wherein said backing plate 3 is the flexible material of electrostatic prevention.
Crystal oscillator oscillation test fixture of the present invention, wherein said web member are five groups, are located at four jiaos and center of location-plate 1 respectively.
Crystal oscillator oscillation test fixture of the present invention is provided with bullet pad and plain cushion between wherein said screw 5 and the pressing plate 2.
The beneficial effect of crystal oscillator oscillation test fixture of the present invention:
1. can disposablely carry out vibration experiment simultaneously to tens of crystal oscillators;
2. save time, power saving, cost-saving;
3. safe and reliable.

Embodiment
Detailed structure of the present invention, application principle, effect and effect with reference to accompanying drawing 1-4, are illustrated by following embodiment.
Consult shown in Fig. 1-4, crystal oscillator oscillation test fixture of the present invention, constitute by location-plate 1, pressing plate 2, backing plate 3 and web member, 30 tested crystal oscillators 4 are arranged between the location-plate 1 of being located at top and the backing plate 3 of being located at the bottom by horizontal 5, vertical 6 mode, every tested crystal oscillator 4 number of pins are 4, pass the corresponding aperture on the location-plate 1 respectively.Backing plate 3 belows are provided with pressing plate 2; Aforementioned location-plate 1, pressing plate 2, backing plate 3 are fixedly connected by five groups of web members, web member is located at four jiaos and center of location-plate 1 respectively, every group of web member is made of screw 5 and nut 6, screw 5 passes corresponding aperture on location-plate 1, pressing plate 2, the backing plate 3, be connected on location-plate 1 with nut 6, be provided with bullet pad and plain cushion between screw 5 and the pressing plate 2; Location-plate 1 is provided with the perforate that matches with the crystal oscillator pin 7 of tested crystal oscillator 4.
The purpose of vibration is to observe tested crystal oscillator 4 inner structures, circuit and assembly quality, therefore according to the position of its structural design location pin, during vibration pin is penetrated in the location-plate 1 corresponding hole, and the diameter in hole is than the big 0.2～0.4mm of leg diameter.
Crystal oscillator is a metal shell, and pressing plate 2 is a metal material also, and both combine closely, and vibrates to produce friction again, can cause the damage of crystal oscillator outward appearance or cause the crystal oscillator internal injury.Therefore select that certain thickness is arranged, certain elasticity and material (being backing plate 3) with anti-static effect be attached on the pressing plate.
