Abstract
The invention discloses an adhesive structured pigtail type detector which comprises a rubber sheath, an optical fiber assembly, a metal shell and a detector chip, wherein the optical fiber assembly and the metal shell are connected; the optical fiber assembly and the detector chip are coupled; the detector chip and the metal shell are bonded by glue; and an outer circle of the optical fiber assembly is provided with a platform. The adhesive pigtailed detector has the advantages that a gap between the optical fiber assembly and the inner part of the metal shell is reserved by changing the structure of the optical fiber assembly, which is beneficial to the exhausting of gas generated in the curing of the glue so as to prevent the glue from bubble burst; the index of the detector is ensured to reach the standard all the time, be free from the influenced of the processing course; the production cost is reduced; and the product reliability is better.
Description
Technical field
The present invention relates to a kind of detector that is used to receive the CATV signal, especially relate to a kind of adhesive structure tail fiber type detector.
Background technology
The existing detector that is used to receive the CATV signal, principle of work are that 1550nm wavelength light signal transmits by optical fiber component, are detected and convert electric signal access TV after the device chip receives again to.Its structure comprises rubber sheath 1, optical fiber component 2, betal can 3, detector chip 4 and aperture 5 as shown in Figure 1.Wherein: optical fiber component 2 and betal can 3 adopt gluing connect form and be connected after, with detector chip 4 couplings, after the responsiveness index reaches requirement, adopt glue that detector chip 4 and betal can 3 is bonding again, high temperature is with adhesive curing then.Because the device inside space is sealing during adhesive curing, the inner air expanded by heating can go out the glue explosion aperture, may cause index to be run away (being that index does not reach requirement) like this, and outward appearance is also defective.For fear of the generation of this phenomenon, conventional way is processing one aperture 5 on betal can 3, is used for exhaust.The shortcoming that this kind way exists is: aperture processing has not only increased the processing cost of product, and has influenced the integrality and the consistance of product surface shape.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of adhesive structure tail fiber type detector.
The technical solution adopted for the present invention to solve the technical problems is: a kind of adhesive structure tail fiber type detector, comprise rubber sheath, optical fiber component, betal can, detector chip, optical fiber component is connected with betal can, optical fiber component and detector chip coupling, detector chip and betal can adopt gluing connecing, and the cylindrical of optical fiber component is provided with platform.
The degree of depth of described platform is 0.01 to 0.5mm; Described optical fiber component adopts interference wringing fit press-fit approach to be connected with betal can.
Compared with prior art, good effect of the present invention is: by changing the structure of optical fiber component, make optical fiber component and betal can inside leave the gap, help the gas discharge that glue is produced when solidifying, avoid the quick-fried bubble of glue, the index that has guaranteed detector keeps up to standard always, is not subjected to the influence of process; And,, guaranteed the integrality and the consistance of product surface shape to the not influence of profile of whole detector owing to be the change of inner structure; Compare with the technical scheme of processing aperture in the prior art on betal can, the structure of band platform directly is processed into the cylindrical of optical fiber component in the present invention, reduced production cost, and reliability of products is better.
Description of drawings
The present invention will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of existing detector;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is the structural representation that optical fiber component of the present invention and platform are provided with.
Embodiment
A kind of adhesive structure tail fiber type detector as shown in Figure 2, comprises rubber sheath 1, optical fiber component 2, betal can 3, detector chip 4 and platform 6.
As shown in Figure 3, add man-hour at optical fiber component 2, platform 6 of processing on its cylindrical, the degree of depth is 0.01 to 0.5mm, best results when wherein the degree of depth is 0.1mm, neither can be because of the slit between optical fiber component 2 and the betal can 3 make dust and impurity enter device inside easily too greatly, also can be not bad because of the too little air permeable effect of device that makes in the slit between optical fiber component 2 and the betal can 3.The number of platform is not limited to one, also can be two or more, can match with the degree of depth by the number of platform, selects the most appropriate the platform number and the platform degree of depth on the basis of taking all factors into consideration processing cost and properties of product.Optical fiber component 2 and betal can 3 adopts the interference wringing fits to press-fit form to combine, leave the gap with two inside of frock control then, and these gaps have just guaranteed that glue can discharge gas when solidifying, avoid the quick-fried bubble of glue, after being cured, again rubber sheath 1 is pushed to, covered the gap.
Why optical fiber component 2 and betal can 3 adopt the interference wringing fits to press-fit form, are because this mode adopts the gluing efficient height that form is connected that connects than of the prior art with optical fiber component 2 and betal can 3, and technology simply and saved the cost of glue.
Claims (3)
