The utility model discloses an anti electrostatic interference's optical device has solved and can not avoid producing because of equipment is inside the static electric current among the prior art and lead to the fact the problem of interference to the device, utilizes being connected of plastic port and metal parts, and protective apparatus on the optical device is conducted in prevent static electricity or thunderbolt.
Description
Technical field
The utility model relates to optical communication field, particularly relates to a kind of antistatic optical device.
Background technology
Along with the development of optical communication technology, the function of optical communication equipment from strength to strength, optical communication bandwidth also requires more and more higher, this just needs optical communication module transfer speed to improve constantly, the density of transmission line also improves constantly, make optical module responsive all the more to disturbing such as thunder and lightning, equipment more easily damages after suffering static discharge or thunderbolt, the annual whole world have tens million of equipment because of thunder and lightning reason damaged, and causing the economic loss of hundreds billion of unit, this will deluster device and equipment all need good antistatic effect.
Optical device is the chief component of optical module, and optical device is divided into light emitting devices TOSA and light receiving element ROSA according to function, and along with the development of miniaturization, the two unites two into one and just defines light launch and accept device BOSA.When encapsulating optical module, adopting antistatic optical device to be arranged in module housing, making Whole Equipment to resist strong jamming, such as, when thunderbolt or electrostatic, by interference surge non-conducting on optical device, thus device signal can not had an impact.
Optical device and optical module responsive all the more to disturbing such as thunder and lightning, equipment suffer static discharge or thunderbolt after more easily damage.Antistatic jamming program common in prior art is by optical module and equipment shell ground connection, weakens the damage of static discharge or thunderbolt, but the damage that thoroughly can not solve static discharge like this or be struck by lightning to optical module and equipment.
Utility model content
In view of this; in order to overcome the problem can not avoiding causing device because device interior produces electrostatic induced current interference of the prior art; the utility model provides a kind of antistatic optical device; utilize the connection of plastic cement port and metal parts, prevent electrostatic or thunderbolt to be transmitted to proterctive equipment on optical device.
In order to solve the problem, antistatic optical device of the present utility model comprises: optical coupling part and luminous component and for fixing both make the accessory of both cooperatings, described accessory comprises: plastic cement tube core, ceramic sleeve, metal die and metal base; Described metal base is buckled on described luminous component, and described plastic cement tube core is fixedly connected with described metal die, and its interior hollow section forms optical channel, and described optical coupling part is positioned at this optical channel; Described metal die is fixedly connected with described metal base.
Further, described luminous component is LD-TO.
Further, described optical coupling part is ceramic insertion core, and described ceramic insertion core one end is fixed in described metal die, and the other end is nested on ceramic sleeve, described ceramic sleeve be fixed on described plastic pipe in-core.
Compared with prior art, advantage of the present utility model is: antistatic optical device of the present utility model is fixed optical coupling part and luminous component by metal die, metal base and the plastic cement tube core utilizing machining precision low, owing to have employed the plastic cement tube core that insulating material is made, when making to utilize this optical device to carry out light module package, avoid the formation of internal electrostatic electric current, when making optical module run into thunderbolt or electrostatic, interference surge can not be transmitted on optical device, thus does not have an impact to device signal.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of antistatic optical device of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
In the present embodiment, antistatic light emitting devices as shown in Figure 1, comprise ceramic insertion core 3 and LD-TO6, and for being fixedly connected with above-mentioned optical coupling part and luminous component, make both can the accessory of cooperating, these accessories comprise: plastic cement tube core 1, ceramic sleeve 2, metal die 4 and metal base 5; Be provided with light source receiving cavity in metal base 5, the luminous site of LD-TO6 is placed in light source receiving cavity, makes metal base 5 be buckled on LD-TO6; Metal die 4 is in hollow columnar structures, plastic cement tube core 1 is also in hollow columnar structures, plastic cement tube core 1 is press-fitted by metal die 4 or glue is connected, both hollow spaces form optical channel, ceramic sleeve 2 and ceramic insertion core 3 are positioned at this optical channel, one end of ceramic insertion core 3 is fixed in metal die 4, and the other end is nested in ceramic sleeve 2, and ceramic sleeve 2 is fixed on plastic cement tube core 1; Metal die 4 and metal base 5 are welded and fixed, and LD-TO6 produces light signal as light source, and light signal outwardly transmits after carrying out optically-coupled by ceramic insertion core on optical channel 3.
When utilizing the antistatic light emitting devices encapsulation in Fig. 1 to form optical module, the part that this light emitting devices contacts with the metal shell of optical module only has plastic cement tube core 1, insulation avoids the formation of internal electrostatic electric current, when running into thunderbolt or electrostatic, interference surge can not be transmitted on optical device, thus does not have an impact to device signal.
Above-mentioned plastic cement tube core 1 is made up of plastic material, and intensity is high, and the life-span is long, batch processing can process, thus significantly improves finished product rate, ensure that the technical indicators such as consistance, improve product quality; Meanwhile, metal die 4 and metal base 5 machining precision low, antistatic cost is lower.
More than describe preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple equivalents to the technical solution of the utility model, these equivalents all belong to protection domain of the present utility model.
