Abstract

The invention discloses a centrifugation test clamp with a fiber type Y waveguide device. The centrifugation test clamp comprises a cover plate, an outer gasket, an inner gasket and a device mountingseat which are sequentially mounted from outside to inside, wherein an end surface of the device mounting seat is provided with a column-shaped groove, a plane of a bottom portion of the groove is atleast provided with a fixed groove A which is matched with the to-be-tested Y waveguide device in size and shape, a fixed groove B used for fixing fiber is arranged between the middle portion of the fixed groove A and an edge of the bottom portion of the groove, the fixed groove A and the fixed groove B are mutually communicated, and the inner gasket is provided with a pad A which extends towardsthe fixed groove A and is mutually matched with the fixed groove B. The centrifugation test clamp is advantaged in that a problem of low work efficiency caused by replacement of the clamp during a centrifugation test, a vibration test and an impact test existing in a Y waveguide device in the prior art is solved, efficiency of the Y waveguide device during a mechanical test is substantially improved, and the completion time of three tests accomplished by the Y waveguide device is shorted by one third.

Description

technical field [0001] The technical field of the invention relates to mechanical environment test equipment, in particular to a centrifugal test fixture with an optical fiber type Y waveguide device. Background technique [0002] In the prior art, the Y waveguide device is one of the important basic optical waveguide units in integrated optoelectronics, and is widely used in integrated optical devices such as optical couplers, optical demodulators, optical switches, and fiber optic gyro multifunctional chips. The quality of its performance is directly related to the quality of these devices. Therefore, Y-waveguide device products need to undergo various tests such as centrifugal test, vibration test, and impact test. It is prone to the problem of fiber breakage, and the problem of low work efficiency caused by changing the fixture when the Y waveguide device is doing centrifugal test, vibration test and impact test. Contents of the invention [0003] In view of this, the...
