The assembly structure of the isolation elements of optoisolator in the past generally is fixed in the magnetic tube by four angles and the magnetic tube of viscose glue mode with core members, because above-mentioned bonding way connects by the some contact, connected mode makes that the stability of optoisolator can not get ensureing like this, and inconvenient operation is brought certain degree of difficulty to production technology like this.
Moreover the optoisolator core members is bonded in the end of fibre-optical splice, may bring light path that glue is arranged, thereby influences its light path performance and its inconvenience of doing over again, thereby is not suitable for producing in enormous quantities.
Summary of the invention
Given this, be necessary to provide a kind of and can realize the optoisolator spare of encapsulation fast.
To achieve these goals, the utility model provides a kind of optoisolator spare, comprise a core members and a magnetic tube that a fixture, is made of polaroid and Faraday rotor, core members is contained in the described fixture, the described fixture that contains core members is placed in the described magnetic tube, described fixture is made up of base portion and two equidistant arms, these two equidistant arms extend from the same side of this base portion, and these two equidistant arms are equipped with light hole, can pass two light holes perpendicular to equidistant arm direction light beam.
Wherein, preferred version is: the medial surface of described equidistant arm is the dip plane, and the medial surface of two equidistant arms parallels.
Wherein, preferred version is: described base portion is used for fixing described core members.
Wherein, preferred version is: described equidistant arm is for circular.
Wherein, preferred version is: described two light hole sizes are identical.
Wherein, preferred version is: the inwall of described fixture and described magnetic tube matches.
Wherein, preferred version is: described fixture is ceramic material or glass material or metal material.
Wherein, preferred version is: described core members and fixture are bonding with glue.
Owing to adopted above-mentioned optoisolator spare, the processing quantity and the packaging technology of the part that not only simplifies the structure in the process of production and assembly have been saved the time, have also saved the yield that production cost has improved product.
