Abstract

A splicer (20) comprises a chassis (22) with an opening, in which a splicing unit (10) for splicing optical waveguides (18) is arranged. The splicer can be controlled using a control and display apparatus (26). A splicing cassette carrier (24) is arranged on the chassis (22) such that it can rotate. The splicing cassette carrier is designed such that it can be used both for fixing a splicing cassette but also as a carrying handle for the splicer. The splicer furthermore has a control unit (34) via which the splicer is switched into an active operational state or a stand-by mode, depending on the rotation position (71, 73) of the splicing cassette carrier. If the splicing cassette carrier is open, a light intensity of a background illumination of the display apparatus (26) and a light intensity of an illumination device (63) can be controlled in a variable manner. On account of the reduced power consumption associated therewith, it is possible to extend the operational readiness of the splicer.

Technical field

The present invention relates to a kind of contact maker with splicing cassette carrier (carrier), this carriage plays the effect that keeps engaging case when optical waveguide or fiber splices are in contact maker.The invention still further relates to portable or portable light contact maker, it can be transported and used by an operator, with at the inner or outside joint that carries out optical fiber of containment building.

Background technology

Though contact maker is particularly useful for engaging optical waveguide and optical fiber, contact maker also can be applicable in the wide technical.Portable contact maker is particularly suited for using on the spot, and for example can be used for fiber splices in mast or underground cable.Suchlike mobile contact maker generally includes joint unit, control and display unit, contraction unit and holds the chassis (chassis) of these unit.This contact maker has subsidiary splicing cassette carrier usually, is used for holding the required joint case of joint.The optical fiber that has been bonded in the joint unit is inserted in the joint case, with the clear arrangement of optical fiber that keeps having engaged during engaging other optical fiber.Engaging case generally comprises openable plastic casing and is integrated in the maintenance equipment that wherein is used to keep fiber optic splicing.

Fig. 7 shows an example of joint unit.That will be joined together and two fibre ribbons with optical fiber 18 before their terminal slightly weakness be separately fixed in the optical fiber holder 16, and be positioned at (X, Y and Z direction) on the mobile unit that is not illustrated, to engage.The end of optical fiber 18 is aimed at by means of introducing has the groove of optical fiber.Suppose that optical fiber preferably is arranged in single groove, so only need to aim at mobile unit.In an improved embodiment, also available detecting device and light source, thus adjust optical fiber end relative to each other.

In case two ends of single optical fiber 18 have moved on the position near each other, apply voltage subsequently between the electrode 14 that is kept by electrode holder 12, cause forming thermic arc.Each optical fiber end then is welded together under this heat affecting of having a mind to.

The user of contact maker carries out the predetermined actions order to carry out fiber optic splicing.Contact maker is positioned on smooth firm surface or the pedestal, to carry out engagement step.At first, remove the shell of the cable end that exposes of cable, the fibre coating on each optical fiber of removing cable subsequently and being comprised.There is not the end of protection to insert in the optical fiber holder 16 simple optical fiber.The joint case 36 that is used for the simple optical fiber that has engaged is carried out multiple joint also is provided.For this purpose, can choose wantonly and use the splicing cassette carrier that can be positioned with the joint case on it.Suchlike splicing cassette carrier is normally permanent adaptive with contact maker, can be installed in contact maker (screw keep, with hook hook etc.) on, perhaps can be sidelong along contact maker one simply and put.

Two optical fiber holders 16 that have the anchor portion of optical fiber 18 are inserted into joint unit 10.Joint unit 10 is located at inside, chassis in shielded mode, after the opening that is provided with the lid that is used to protect meticulous mechanism.In case contact maker is in place, the splicing cassette carrier setting puts in place and to have the optical fiber holder of optical fiber end ready, will be by control and/or display device operating contact maker.Engaging process is controlled by the control zone.The status information that the viewing area demonstration is relevant with engaging process itself with adjusting.In case engaging process is finished, pull down engaging the good opening 30 of fibre ribbon from joint unit 10 or chassis, and be sent to the contraction unit.During this process, shrinkage sleeve is being retracted under the influence of heat on the abutment of optical fiber 18, with the protection cable.

Splicing cassette carrier is preferably placed at the back side of contact maker.This is because in this case, and moving process can followingly carry out: at the beginning, optical fiber is inserted in the joint unit, become by collapse step and engage good optical fiber, this optical fiber that engages is placed in the joint case on the direction of the device back side.This be because, visible as the operator, joint unit is aimed in the front of contact maker, shrink the unit simultaneously and be arranged on it behind, splicing cassette carrier is positioned on the back side of device, the result, the optical fiber that has been put down and engaged can not enter another engaging process once more.

Contact maker there is strict requirement, especially uses on the spot in the containment building outside.The improvement process of fine structure has caused the demand of the protection of for example guaranteeing to obtain better to resist dust and rocking in the joint unit.Yet for the reason of ergonomics, Design of device must be so unheavy, and should avoid the additional protection measure to cause weight to increase.

Summary of the invention

This problem and only be that the other problems of mentioning can solve by so a kind of splicing cassette carrier here, this carriage can keep engaging case in the optical waveguide in engaging contact maker, and it comprises: have the plate on plane, this plate is used for keeping engaging case; At least one bracket arm, this bracket arm is connected to and support plate; And make at least one bracket arm can be attached in equipment on the chassis of contact maker, and described equipment is installed into and can rotates around axis, thus splicing cassette carrier can be done the pivot motion around described axis.

These problems also can solve by following contact maker, and this contact maker comprises: chassis, the equipment that this chassis has at least one opening and is used for rotatably installing above-mentioned splicing cassette carrier; Engage the joint unit of optical waveguide, joint unit is arranged in the opening on chassis; Control that control engages and/or demonstration are provided with, and this control and/or display device are arranged in the chassis; And above-mentioned splicing cassette carrier; this splicing cassette carrier is rotatably installed on the chassis by described equipment; thereby it can take first position of rotation and at least one second position of rotation; it is used to keep engaging case on first position of rotation, and it serves as the lid of protection control and/or display device on second position of rotation.

An idea that the present invention is based on is that splicing cassette carrier is attached to the chassis, thereby it not only can be used for it keeps engaging case between joint aging time specific purpose, also can play the effect of the lid of control and/or display device extraly before or after engaging process.This purpose can thereby rotatable splicing cassette carrier be achieved on the chassis by being installed in.

Therefore, splicing cassette carrier can move on another position of coverage control and/or display device from the primary importance that can keep engaging case.Thereby splicing cassette carrier brought into play dual-use function, and just it also can be used for protecting the system unit of contact maker extraly.Therefore, relatively Min Gan parts can be used for controlling and/or the zone of display device in, such as TFT display that under the situation of effective protection of not resisting physical damage, dust, dirt and cold or moisture effect, can not use or meticulous keyboard elements.In addition, lid also can protect the function key in the control zone not to be subjected to neglecting pushing of causing.Thereby many improvement of suchlike splicing cassette carrier tolerable contact maker.
