Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Instance one
See also Fig. 1 to Fig. 6, a kind of fused fiber splice point protection device comprises first body 10, second body 20, renovates 30 and locking device 40.
First body 10 can be made into integration with both ends 12,13 by our department 11.Both ends 12,13 lay respectively at the two ends of our department 11, and our department 11 is provided with or forms one first accepting groove 14 along body itself, and are same, and both ends 12,13 also form two second accepting grooves 15 along its body itself, and communicate with first accepting groove 14 respectively.In this example, the slot aperture of first accepting groove 14 of our department 11 can be slightly larger than second accepting groove 15, can ccontainingly contain the thermoplastic sleeve pipe at fiber alignment place.That is, second accepting groove 15 that both ends 12,13 form can be less than the aperture of first accepting groove 14, and our department 11 of first body 10 can form step or the progressive shape that dwindles with the junction at two ends 12,13 on the periphery.In this example, both ends should be less than the periphery near our department 11 away from the periphery of our department's 11 parts, and best is that the periphery size at both ends 12,13 begins progressive dwindling from the junction of our department 11.
Second body 20 can be connected with first body 10 by a variety of modes.In this example, a side of second body 20 is articulated in a side of first body 10, and the opposite side of second body 20 is connected in the respective side of first body 10 with the mode of buckle 16.Buckle 16 processing eases and for convenience detach.Second body 20 is many especially with the means that first body 10 is connected, and only is for example at this.Second body 20 can form first accommodation space of a ring-type with after first body 10 is connected.
Renovate 30 and different angles can be set be rotatably connected at the end face of second body 20, be locked on first body 10 through locking device 40, renovate 30 and first body 10 and form second accommodation space, first accommodation space and second accommodation space communicate.
Renovate 30 and different angles can be set be rotatably connected, realize that the physical construction of this function is also very many at the end face of second body 20.Two post positions 21 are set respectively on the right ends of one end face of second body 20, renovate and comprise the portion of being rotatably connected 35 and Access Division 36.Be rotatably connected portion 35 can be made into integration with Access Division 36, and be rotatably connected portion's 35 correspondence position settings and two post positions 21 are provided with adaptive position, two holes 33, and the cooperation through post position 21 and position, hole 33 is rotatably connected on second body 20 with renovating 30 different angles.For the ease of renovating better assembling, be convenient to renovate the gathering sill 34 that 30 and second body 20 installs renovating also to be provided with on 30.When assembling was renovated, guide effect was well played in coupled columns position 21.The structure of portion 35 and Access Division 36 of being rotatably connected is corresponding with first body 10, so that be rotatably connected portion 35 and Access Division 36 are connected to 10 last times of first body respectively, can be mated; Form second accommodation space, that is, form an inner wall groove 37 on the Access Division 36; Suitable with second accepting groove, 15 apertures; This inner wall groove 37 and second accepting groove 15 are formed second accommodation space, and identical with second accepting groove, 15 length or the near possibility of inner wall groove 37 is identical.And Access Division 36 periphery sizes begin progressive dwindling from the junction near the portion of being rotatably connected 35.
In this example, the inwall of Access Division forms the chucking structure in order to chucking rubber-insulated wire cable and wire jumper.Such as, the chucking structure comprises at least one projection group 38 vertical with inwall slotted eye direction, projection group 38 is made up of a plurality of pillars that protrude out inwall successively.
Locking device can comprise lid, and lid can be screwed onto to be renovated on 30 and first body 10.Lid can be that the port of screwing is gradually little to the bottom, conveniently screws and renovates 30 and first body 10.The outer wall of lid radially is provided with the U type groove 44 that makes things convenient for turn-knob.Lid is near on the end face of renovating with first body some spline grooves 43 being set.Renovate on 30 and first body 10 and be provided with and the adaptive screw thread 17,39 of inner lid respectively.
In general, renovate and comprise that first renovates 31 and second and renovate 32, the first and renovate 31 and second and renovate 32 and be rotatably connected respectively at the both sides end face of second body 20, each forms one second accommodation space, and it lays respectively at the both sides of first accommodation space.In like manner, lid comprises first lid 41 and second lid 42, covers of tight fused fiber splice point protection device respectively.
Fused fiber splice point protection device uses step:
Rubber-insulated wire cable/wire jumper strip off crust that desire is connected exposes naked fibre, is placed on the cutter and cuts.Then the rubber-insulated wire cable/wire jumper of well cutting is put lid, the thermoplastic sleeve pipe of this protective device respectively, note direction during installation.
Clean optical fiber with alcohol, optical fiber is placed on checks end face on the heat sealing machine then, if qualifiedly carry out welding, defective cutting again.
Put the thermoplastic sleeve pipe after two fused fiber splices are good, be placed on and carry out hot melt in the heat sealing machine hot melt tank.
Two kinds of good optical fiber of hot melt are put in this protective device, after equilibrium is put well, second body are built clamping to the first body.
Push second the renovating downwards of body two ends again,, be seated with first body by corresponding guiding screens.
To renovate buckle compress after, again lid is tightened, tightly pin rubber-insulated wire cable/wire jumper.
Need to prove that above accompanying drawing only is to be explanation usefulness, maybe be really not so under the user mode.Can not limit the use of the utility model with accompanying drawing.
Instance two
See also Fig. 7, the positioner 51 that can clamp the thermoplastic sleeve pipe is set in the accepting groove of first body.Positioner 51 can comprise and be arranged on left fixture block and the right fixture block that is symmetrical set in the accepting groove that left fixture block and right fixture block tighten the thermoplastic sleeve pipe movably.Positioner 51 also can be that other structure or mode realize.
Tension positioner 52 is set in second accommodation space.Comprise such as, tension positioner card 54, the card tie point 53 in second accommodation space are set, card is connected in first body of second accommodation space through the card tie point, and, tension clamping mechanism 55 is set on the card.
See also Fig. 8 again, this fused fiber splice point protection device can press from both sides establishes rubber-insulated wire cable 57, wire jumper 56.The outside dimension of rubber-insulated wire cable and wire jumper is different, and general optical fiber welding protector can not firmly be locked two kinds of cables simultaneously, occurs the movable situation of cable in the use easily, and influence is to the protection effect of fused fiber splice point.The utility model is provided with the chucking structure through to the size design at first body and the chucking cable position of renovating and the tension positioner is set on renovating on first body, can reach to tighten the effect that the rubber-insulated wire cable can tighten wire jumper again.
In addition, the length of first accommodation space is for can hold the length of 60mm with the thermoplastic sleeve pipe of interior all length, and is best for holding the long thermoplastic sleeve pipe of 30-60mm.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
