Refer again to Fig. 5 A, as an illustrative embodiment, the main part 50 of mechanical splice component tray 6 and cable clamping part 51 manufacture one (that is, monolithic construction), and wherein, cable clamping part 51 is extended from main part 50.Xsect due to the anterior 50f of main part 50 is greater than the xsect of rear portion 50r, and the joint of anterior 50f and rear portion 50r defines shoulder 59.Shoulder 59 is for stopping clamping carrier 7 when mechanical splice component tray 6 inserts in clamping carrier 7, but other structure is also fine.Certainly, non-monolithic structure is also fine.But the monolithic construction of main part 50 and cable clamping part 51 makes the joints of optical fibre can have some advantages, such as, there is compacter size, more easily manufacture, more easily assemble, and more firm etc. when installing at the scene.

As shown in Figure 5A, the cavity 52 of mechanical splice component tray 6 can comprise side fluting 56 further, if cam 3 employs cam handle 86 (see Figure 13 A-C), then this side fluting 56 is for holding cam handle 86 (see Fig. 1) when cam 3 rotates the position to working.On the top surface of rear portion 50r, shoulder 59 is formed with opening 57a, and be formed be positioned at this opening 57a before or among Breech block 58a.Symmetrically, in the lower surface of rear portion 50r, shoulder 59 is formed with opening 57b, and be formed be positioned at this opening 57b before or among Breech block 58b, as shown in Fig. 5 C-D (Fig. 5 C-D is the bottom perspective view of the amplification of mechanical splice component tray 6 in Fig. 2).Two opening 57a and 57b are for receiving locking ear 72a and 72b (as shown in Figure 10 A) on clamping carrier 7.In order to fixed clamp bracket 7 better, each Breech block 58a, 58b have the slope of rising.Those skilled in the art it should be noted that other is also fine for the structure be fixed on mechanical splice component tray 6 by clamping carrier 7, such as, clamping carrier forms Breech block, and form opening or window on mechanical splice component tray 6.

Still with reference to figure 5A, the cable clamping part 51 on mechanical splice component tray 6 has a pair clamping limb 60a and 60b, and this is at least two group bites of fiber optic cables clamping limb 60a and 60b had for different size and/or type.That is, mechanical splice component tray 6 can receive multiple different cable, thinks that technician provides terminal dirigibility (terminationflexibility).In shown illustrative embodiment, this has three groups of bites to clamping limb 60a and 60b, and it is for such as kind of dissimilar fiber optic cables of three shown in Fig. 8 A-C.In addition, clamping limb has concept at least two group bites of different size and/or type fiber cable independent of the further feature of shown connector, and can be used for any suitable mechanical splice joints of optical fibre.

With reference to figure 8A-C, with explaining, it illustrates the fiber optic cables of three types, comprising: the round cable (that is, the optical fiber of band buffering) of 0.9mm, it covers sheath outward; The outer round cable coated with sheath of 3.0mm, it has cable cover(ing) and aramid fiber, such as and flat (flat-shaped) cable (or arch (bow-shaped) cable) of 2.0x3.0mm.As shown in Figure 8 A, the round cable of 0.9mm comprises optical fiber and the cushion around optical fiber setting.Because the diameter covering the 0.9mm round cable of sheath is outward very little, for clamping this 0.9mm round cable, clamping limb 60a and 60b has first group of bite 61a and 61b, and this has a pair flat surface (being clearly shown that in fig. 5) to bite.

As shown in Figure 8 B, the outer round cable coated with sheath of 3.0mm comprises optical fiber, the cushion around optical fiber setting, the reinforcement material layer around cushion setting (such as or reinforcing cord), and around the sheath of reinforcement material layer.Because 3.0mm is outer larger than the diameter of 0.9mm round cable coated with the diameter of the round cable of sheath, clamping limb 60a and 60b has second group of bite 62a and 62b, this has a pair larger semicircular surface to bite, fixes this 3.0mm round cable to form larger circular enclosure (see Fig. 5 A).

The joints of optical fibre disclosed herein are also applicable to sturdy (rugged) cable with hard reinforcement material to be connected in terminal, make this cable be applicable to outdoor application thus.As shown in Figure 8 C, the flat cable of 2.0x3.0mm comprises optical fiber, is arranged on a pair glass fiber reinforced plastics (GRP) reinforcement material of optical fiber both sides, and fire-retardant corrosion-free (FRNC) sheath of the general flat arranged around optical fiber and GRP reinforcement material.According to an embodiment, also there is the 3rd group of bite 63a and 63b (see Fig. 5 A) for fixing this 2.0x3.0mm flat cable.More particularly, as shown in Figure 5A, a pair arm 70a and 70b is arranged on the upper edge of the 3rd group of bite 63a and 63b, to form the profile of the flat pattern being suitable for fixing this flat cable.

Those skilled in the art be it should be noted that, in the disclosure, the clamping diameter of three groups of bites or width are set to increase gradually along two clamping limb 60a and 60b towards its end (or far-end), thus negative effect can not be used for another of another kind of type fiber cable to bite for a kind of a pair bite of type fiber cable.Also noteworthy is that, principle of the present invention and spirit are equally applicable to such structure, that is, clamping limb 60a and 60b has one group or two groups of bites or more than three groups of bites.

Same be worth those skilled in the art it is to be noted that, the feature in the present invention with multiple bite is also applicable to the fiber optic cables except other type shown in Fig. 8 A-C and/or size, such as, the outer round cable coated with sheath of 1.9/1.6mm and the outer round cable coated with sheath of 2.9/2.4mm.

Refer again to Fig. 5 A, cable clamping part 51 has groove 65, enters in mechanical contiguous sets part housing 5 for guiding the optical fiber in fiber optic cables.As shown in Figure 5A, groove 65 extends from the main part 50 of mechanical splice component tray 6, and has a pair groove sidewall 66a and 66b and trench bottom 67 (see Fig. 6 A-B and 9A-B).

With reference to figure 13A-C, which respectively show two skeleton views and a side view of Fig. 2 cam 3.As shown in Figure 13 A-C, cam 3 has handle 86 and main body 87.Cam handle 86 has breach 90, for receiving the locking ear 72a on clamping carrier 7 when mechanical splice component tray 6 inserts in clamping carrier 7.Cam body 87 also comprises the through hole 88 and a pair symmetrically arranged protruding 89a and 89b with eccentric circumference, and through hole 88 is for receiving and holding mechanical splice assembly housing 5, protruding 89a and 89b for lifting Liang Ge locking ear 72a and 72b on clamping carrier 7.In order to lift the locking ear 72a on clamping carrier 7 exactly, protruding 89a be arranged on the breach 90 in cam handle 86 below or near, thus when mechanical splice component tray 6 inserts in clamping carrier 7 and cam 3 is in off-position, the locking ear 72a on clamping carrier 7 is positioned at the top of the protruding 89a on cam 3.In an installation, for being installed on mechanical splice assembly housing 5 by cam 3, mechanical splice assembly housing 5 inserts in the through hole 88 of cam 3.When cam 3 is in off-position, mechanical splice assembly housing 5 loosely is arranged in this through hole 88.And when cam 3 rotates to locked position, the fin 36 on the top surface of the eccentric part extruding continual-connecting-part 25a of through hole 88, thus the optical fiber 102 in fiber optic cables 100 and fiber stub 24 can be clamped in wherein by continual-connecting-part 25a and 25b.

With reference to Figure 14, it illustrates when cam 3 is in off-position, the skeleton view of cam 3, mechanical splice component tray 6, clamping carrier 7 and connector shell 8 rigging position each other.As shown in figure 14, because the locking ear 72a on clamping carrier 7 is through the opening 57a on mechanical splice component tray 6, and the left hand edge of locking ear 72a inserts in the breach 90 in cam handle 86, and the blocking mechanism 73a on locking ear 72a aligns with the Breech block 58a on mechanical splice component tray 6.But, because the locking ear 72a on clamping carrier 7 is positioned at the top of the protruding 89a of cam 3, blocking mechanism 73a on locking ear 72a is lifted above the Breech block 58a that is positioned on mechanical splice component tray 6, stops Breech block 58a to be engaged/clamping with blocking mechanism 73a thus.Because it is symmetrical arranged, the locking ear 72b on clamping carrier 7 is also through the opening 57b on mechanical splice component tray 6, and this makes the blocking mechanism 73b on locking ear 72b align with the Breech block 58b on mechanical splice component tray 6.But, because the locking ear 72b on clamping carrier 7 is positioned at the top of the protruding 89b of cam 3, blocking mechanism 73b on locking ear 72b is lifted above the Breech block 58b that is positioned on mechanical splice component tray 6, stops Breech block 58b to be engaged/clamping with blocking mechanism 73b thus.Therefore, in fig. 14, cam 3 is in off-position, and wherein, mechanical splice component tray 6 freely can insert clamping carrier 7 or pull out from clamping carrier 7.

In the operation of working making connector, when cam 3 rotates to locked position as shown in Figure 12 B from the off-position shown in Figure 14, Breech block 58a and 58b on mechanical splice component tray 6 is engaged/clamping with blocking mechanism 73a and 73b on clamping carrier 7, is connected on clamping carrier 7 by mechanical splice component tray 6 thus.More specifically, when cam handle 86 to rotate from the left hand edge of locking ear 72a to its right hand edge cross over locking ear 72a time, two protruding 89a and 89b on cam body 87 move away locking ear 72a and 72b of clamping carrier 7.When cam handle 86 arrives the chute 83 on guard shield 9, two protruding 89a and 89b on cam body 87 are shifted out by locking ear 72a and 72b from clamping carrier 7.Therefore, two Breech block 58a and 58b on mechanical splice component tray 6 are engaged/clamping with blocking mechanism 73a and 73b of two on clamping carrier 7, thus mechanical splice component tray 6 are connected to clamping carrier 7.

Make in the inoperative operation of connector, when cam 3 rotates to off-position from locked position, two blocking mechanism 73a and 73b on clamping carrier 7 are lifted and leave two Breech block 58a and 58b on mechanical splice component tray 6, are discharged by mechanical splice component tray 6 thus from clamping carrier 7.More particularly, when cam handle 86 to rotate from the right hand edge of locking ear 72a to its left hand edge cross over locking ear 72a time, two protruding 89a and 89b on cam body 87 move towards locking ear 72a and 72b of clamping carrier 7.When cam handle 86 arrives the left hand edge of locking ear 72a, two protruding 89a and 89b on cam body 87 move to the below of locking ear 72a and 72b of clamping carrier 7.Therefore, two blocking mechanism 73a and 73b on clamping carrier 7 are lifted two Breech block 58a and 58b left on mechanical splice component tray 6, are discharged by mechanical splice component tray 6 thus from clamping carrier 7.

It should be noted that the joints of optical fibre 20 disclosed herein provide one and connector is worked/inoperative mechanical hook-up, its make connector work/inoperative operation in easily operation and without any need for instrument, also can not damage any parts.Also noteworthy is that, if technician has by mistake pulled clamping carrier 7, the fiber optic cables being connected to the joints of optical fibre 20 can stand larger pulling force, this is because now pulling force is born by Liang Ge locking ear 72a and 72b on Breech block 58a and 58b of two on mechanical splice component tray 6 and clamping carrier 7, instead of born by fiber optic cables.Therefore, the joints of optical fibre 20 are reversible (reversible), and can not damage or destroy optical fiber and connect machine 20, and still can provide firmly connector.Also merit attention and be, the reinforcement material of fiber optic cables make connector inoperative/reciprocal (reverse) operation of working in can not be damaged.
