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

Still with reference to figure 5A, the cable clamping part 51 on the mechanical splice assembly carriage 6 has a pair of clamping

limb

60a and 60b, and this is to having at least two group bites for the fiber optic cables of different size and/or type on clamping limb 60a and the 60b.That is to say, mechanical splice assembly carriage 6 can receive multiple different cable, thinks that the technician provides terminal dirigibility (termination flexibility).Shown in illustrative embodiment in, this has three groups of bites to clamping

limb

60a and 60b, it is used for three kinds of dissimilar fiber optic cables shown in Fig. 8 A-C.In addition, clamping limb have concept at least two group bites of different size and/or type fiber cable be independent of shown in the further feature of connector, and can be used for any suitable mechanical splice joints of optical fibre.

With reference to figure 8A-C, with explaining, the fiber optic cables that it shows three types comprise: the round cable of 0.9mm (that is, the optical fiber of band buffering), its not outer sheath that covers; 3.0mm outer round cable coated with sheath, it has cable cover(ing) and aramid fiber, for example And flat (flat-shaped) cable of 2.0x 3.0mm (or arch (bow-shaped) cable).Shown in Fig. 8 A, the round cable of 0.9mm comprises optical fiber and the cushion that arranges around optical fiber.Owing to the diameter of the 0.9mm round cable that covers sheath outward is very little, be this 0.9mm round cable of clamping, clamping

limb

60a and 60b have first group of

bite

61a and 61b, and this has a pair of flat surface (being clearly shown that) to bite in Fig. 5 A.

Shown in Fig. 8 B, the cushion that the outer round cable coated with sheath of 3.0mm comprises optical fiber, arrange around optical fiber, the reinforcement material layer that arranges around cushion are (for example Or reinforcing cord), and around the sheath of reinforcement material layer.Because the diameter of the outer round cable coated with sheath of 3.0mm is larger than the diameter of 0.9mm round cable, clamping

limb

60a and 60b have second group of

bite

62a and 62b, this has a pair of larger semicircular surface to bite, fixes this 3.0mm round cable to form larger circular enclosure (seeing Fig. 5 A).

Sturdy (rugged) cable that the joints of optical fibre disclosed herein also are applicable to have hard reinforcement material is connected on the terminal, thus so that this cable is applicable to outdoor application.Shown in Fig. 8 C, 2.0x3.0mm flat cable comprise optical fiber, be arranged on a pair of glass fiber reinforced plastics (GRP) reinforcement material of optical fiber both sides, and the general flat that arranges around optical fiber and GRP reinforcement material is fire-retardant without corrosion (FRNC) sheath.According to an embodiment, also have be used to the 3rd group of bite 63a that fixes this 2.0x3.0mm flat cable and 63b (seeing Fig. 5 A).More particularly, shown in Fig. 5 A, a pair of

arm

70a and 70b are arranged on the upper edge of the 3rd group of

bite

63a and 63b, are suitable for fixing the profile of the flat pattern of this flat cable with formation.

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 towards its end (or far-end) along two clamping

limb

60a and 60b, thus a pair of bite that is used for a kind of type fiber cable can negative effect be used for another kind of type fiber cable another to bite.Also noteworthy is that, principle of the present invention and spirit are equally applicable to such structure, that is, clamping

limb

60a and 60b have one group or two groups of bites or more than three groups of bites.

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

Refer again to Fig. 5 A, cable clamping part 51 has groove 65, and the optical fiber that is used for the guiding fiber optic cables enters in the mechanical splice assembly housing 5.Shown in Fig. 5 A, groove 65 extends from the main part 50 of mechanical contiguous sets part carriage 6, and has a pair of

groove sidewall

66a and 66b and trench bottom 67 (seeing Fig. 6 A-B and 9A-B).

With reference to figure 6A-B and Fig. 9 A-B, it illustrates in greater detail the groove 65 among Fig. 5 A.Shown in Fig. 6 A-B (Fig. 6 B is that Fig. 6 A is along the cut-open view of B-B line), mechanical splice assembly housing 5 has inlet tube 98 in its back-end.When mechanical splice assembly housing 5 is installed in the mechanical splice assembly carriage 6, the groove 65 in the mechanical splice assembly carriage 6 and the register of the inlet tube 98 in the mechanical splice assembly housing 5.

Fig. 9 A is the vertical view of mechanical splice assembly carriage 6 among Fig. 5 A, and it shows two

groove sidewall

66a and 66b and be set to have funnel-shaped passage towards the opening of inlet tube 98 between the inboard of two groove sidewall 66a and 66b.Fig. 9 B be Fig. 9 A along the cut-open view of 9B-9B line, such as clearer demonstration in Fig. 9 B, the upper surface of trench bottom 67 raises gradually towards the opening of guiding tube 98.Therefore, under the guiding of two

groove sidewall

66a and 66b and trench bottom 67, the optical fiber in the fiber optic cables can easily be directed behind insertion groove 65 in the opening of the inlet tube 98 of mechanical splice assembly housing 5.In addition, shown in Fig. 6 B, each

groove sidewall

66a and 66b and

corresponding clamping limb

60a or 60b divide out, with the groove 65 that forms half island.The groove 65 of this half island can two clamping limb 60a of negative effect and the dirigibility that moves towards each other of 60b.This mobile dirigibility has strengthened the effect of grip optical fiber cable.

Fig. 5 C shows among Fig. 2 mechanical splice assembly carriage 6 according to the bottom perspective view of the amplification of an illustrative embodiment of the present invention.Shown in Fig. 5 C, on the lower surface of mechanical splice assembly carriage 6, be provided with opening 57b on the shoulder 59, and before the opening 57b or among the position be provided with Breech block 58b.In order to guide better the optical fiber in the fiber optic cables, has the tongue 110 that extends and extend towards the end of cable

grip gripping arm

60a, 60b (or end of arrival

cable keeping arm

60a, 60b) from trench bottom 67.

Fig. 5 D shows among Fig. 2 mechanical splice assembly carriage 6 according to the bottom perspective view of the amplification of another illustrative embodiment of the present invention.Shown in Fig. 5 D, tongue 110 ' extends and extends (or arrive

cable keeping arm

60a, 60b end) towards the end of cable

grip gripping arm

60a, 60b from trench bottom 67.Compare with the embodiment among Fig. 5 C, tongue 110 ' is narrower than trench bottom 67.Because tongue 110 (or 110 ') is what to separate with clamping

limb

60a or 60b, it can two clamping limb 60a of negative effect and the dirigibility that moves towards each other of 60b.

Still with reference to figure 5A, be respectively arranged with two

reinforcement material groove

68a and 68b on the top surface of two clamping

limb

60a and 60b, be used for receiving and hold reinforcement material ( Or rope).Also be provided with two the reinforcement material recess 69a and the 69b that are connected with described two

reinforcement material groove

68a and 68b respectively on the side arm of two clamping

limb

60a and 60b, thereby when fiber optic cables inserted between two clamping limb 60a and the 60b, the outside that

reinforcement material recess

69a or 69b extend to groove 68a or 68b can cross and pass along

groove

68a or 68b to the reinforcement material of fiber optic cables.

Figure 10 A-C illustrates in greater detail the clamping carrier 7 among Fig. 1.Shown in Figure 10 A, clamping carrier 7 has two

front edges

74a, 74b and two 72a of locking ear and 72b.Two

front edges

74a, 74b and two 72a of locking ear and 72b are set to toward each other symmetrically around the main body of clamping carrier 7.Be respectively arranged with two

blocking mechanism

73a and 73b (for example hole or window) on the 72a of locking ear and the 72b, be used for fixed clamp carriage 7.

With reference to figure 10B, it shows the side view of the clamping carrier 7 among Figure 10 A.Shown in Figure 10 B, two 72a of locking ear and 72b on the clamping carrier 7 extend beyond two

front edges

74a and 74b.

With reference to figure 10C, it shows the cut-open view of Figure 10 B 10C-10C along the line.Shown in Figure 10 C, clamping carrier 7 comprises cavity 75, and cavity 75 has the passage that size reduces gradually, and it is used for when the cable clamping part 51 on the mechanical splice assembly carriage 6 is inserted the cavity 75 of clamping carrier 7

clamping limb

60a and 60b being pressed together.Cavity 75 is set to when two clamping

limb

60a and 60b have just entered in the passage of this cavity, cable can loosely between two clamping limbs.Along with two clamping

limb

60a and 60b deeper move into passage gradually, cavity 73 reduces gradually, thus clamping

limb

60a and 60b is pressed together, so that fiber optic cables are clamped in wherein.When the front edges of clamping carrier 7 arrived the shoulder 59 of mechanical splice assembly carriage 6, the movement of clamping limb stopped.

With reference to figure 11A-B, it illustrates in greater detail two skeleton views of the guard shield 9 among Fig. 2.Shown in Figure 11 A, guard shield 9 comprises: be positioned at the opening 81 of its rear end, be used for receiving connector housing 8; U-shaped window 82 is used for holding cam 3; And chute 83, be positioned at the opening edge place of U-shaped window 82, thereby when cam 3 was positioned at locked position, cam handle 86 (as shown in figure 13) can slidably reciprocate along this chute 83.Guard shield 9 also comprises two

reinforcement material recess

84a and 84b, and it can align with two reinforcement material recess 69a and the 69b on the mechanical splice assembly carriage 6.

Figure 12 A shows the step that reinforcement material 104 is connected to the joints of optical fibre 20 in fitting operation.Shown in Figure 12 A, before reinforcement material 104 is connected to the joints of optical fibre 20, the rear end of mechanical splice assembly 2 is inserted in the mechanical splice assembly carriage 6, and the front end of mechanical splice assembly 2 is inserted in the connector shell 8, and connector shell 8 inserts in the guard shields 9.After passage in the cavity 75 that fastener material 104 is passed clamping carrier 7 inserts between two clamping limb 60a and the 60b, fastener material 104 enters one of them groove 68a or the 68b on two clamping limb 60a and the 60b, and passes in two fastener material recess 69a and 69 one of them.Reinforcement material 104 also passes one of them reinforcement material recess 84a or the 84b on the guard shield 9, to arrive the sidewall of guard shield 9.Two clamping limb 60a and 60b enter in the passage of cavity 75 of clamping carrier 7 subsequently, thus one of them of two edge 74a of clamping carrier 7 and 74b promote reinforcement material 104 enter guard shield 9 and be located at the inwall of cavity 75 of clamping carrier 7 and the outer wall of mechanical splice assembly carriage 6 between.Therefore, after the joints of optical fibre 20 installed, reinforcement material 104 was clamped between the outer wall of rear portion 50r of main part 50 of the inwall of cavity 75 of clamping carrier 7 and mechanical splice assembly carriage 6.

Figure 12 B shows the cable assembly 10 that guard shield 9 is not installed.Shown in Figure 12 B, after all other parts that assemble except guard shield 9, the head of reinforcement material 104 extends clamping carrier 7.Make when fiber optic cables 100 in the process of connector inoperative (deactivating) after mechanical contiguous sets part carriage 6 discharges, reinforcement material 104 can be easily and is pulled out from one of them reinforcement material recess 69a of mechanical contiguous

sets part carriage

6 or 69b expediently.

It should be noted that in fitting operation after fiber optic cables 100 were connected to the joints of optical fibre 20, the reinforcement material 104 of fiber optic cables 100 remained on the outside of the guard shield 9 among Fig. 1.Like this be arranged so that the technician can easily observe fiber optic cables 100 and reinforcement material 104 and whether correctly install, and make things convenient for this technician when fiber optic cables 100 are connected to the joints of optical fibre 20, perhaps fiber optic cables 100 are being gripped this reinforcement material 104 when the joints of optical fibre 20 discharge or again fiber optic cables 100 are connected to the joints of optical fibre 20.

Also noteworthy is that, the application provides a kind of mechanical hook-up to the technician, so that its connector is worked (activating) or the operation of again work (re-activating) in easily reinforcement material 104 is fixed on the joints of optical fibre 20, also can in the operation that makes connector inoperative (deactivating), easily reinforcement material 104 be discharged from the joints of optical fibre 20, and not damage this reinforcement material 104.

With reference to figure 13A-C, it shows respectively two skeleton views and a side view of Fig. 2 cam 3.Shown in Figure 13 A-C, cam 3 has handle 86 and main body 87.Cam handle 86 has breach 90, is used for receiving when mechanical splice assembly carriage 6 inserts clamping carrier 7 72a of locking ear on the clamping carrier 7.Cam body 87 also comprises through hole 88 and a pair of symmetrically arranged protruding 89a and the 89b with eccentric circumference, and through hole 88 is used for receiving and holding mechanical splice assembly housing 5, and protruding 89a and 89b are used for lifting two 72a of locking ear and the 72b on the clamping carrier 7.In order to lift exactly the 72a of locking ear on the clamping carrier 7, the projection 89a be arranged on the breach 90 on the cam handle 86 the below or near, thereby when mechanical splice assembly carriage 6 inserts in the clamping carriers 7 and cam 3 when being in the off-position, the 72a of locking ear on the clamping carrier 7 is positioned at the top of the protruding 89a on the cam 3.In installation, for cam 3 is installed on the mechanical splice assembly housing 5, mechanical splice assembly housing 5 inserts in the through hole 88 of cam 3.When cam 3 was in the off-position, mechanical splice assembly housing 5 looselys were 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 of through hole 88 extruding continual-connecting-part 25a, thus continual-connecting-part 25a and 25b can be clamped in the optical fiber 102 in the fiber optic cables 100 and fiber stub 24 wherein.

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

In the operation that connector is worked, when cam 3 rotates to the locked position shown in Figure 12 B from off-position shown in Figure 14, blocking mechanism 73a on Breech block 58a on the mechanical

splice assembly carriage

6 and 58b and the

clamping carrier

7 and 73b interlock/clamping are connected to mechanical splice assembly carriage 6 on the clamping carrier 7 thus.More specifically, when cam handle 86 is rotated to its right hand edge when crossing over the locking 72a of ear from the left hand edge of the 72a of locking ear, two protruding 89a on the

cam body

87 and 89b move away the 72a of locking ear and the 72b of clamping carrier 7.When cam handle 86 arrived chute 83 on the guard shields 9, two protruding 89a and 89b on the cam body 87 were shifted out by the 72a of locking ear and 72b from clamping carrier 7.Therefore, two blocking mechanism 73a on two Breech block 58a on the mechanical

splice assembly carriage

6 and 58b and the

clamping carrier

7 and 73b interlock/clamping are connected to clamping carrier 7 with mechanical splice assembly carriage 6 thus.

In making the inoperative operation of connector, when cam 3 rotates to the off-position from locked position, two blocking mechanism 73a on the

clamping carrier

7 and 73b are lifted and leave two Breech block 58a and 58b on the mechanical splice assembly carriage 6, thus mechanical splice assembly carriage 6 are discharged from clamping carrier 7.More particularly, when cam handle 86 is rotated to its left hand edge when crossing over the locking 72a of ear from the right hand edge of the 72a of locking ear, two protruding 89a and 89b on the cam body 87 move towards the 72a of locking ear and the 72b of clamping carrier 7.When cam handle 86 arrived the left hand edge of the locking 72a of ear, two protruding 89a and 89b on the cam body 87 moved to the 72a of locking ear of clamping carrier 7 and the below of 72b.Therefore, two blocking mechanism 73a on the

clamping carrier

7 and 73b are lifted two Breech block 58a and the 58b that leaves on the mechanical splice assembly carriage 6, thus mechanical splice assembly carriage 6 are discharged from clamping carrier 7.

It should be noted that the joints of optical fibre disclosed herein 20 provide a kind of connector that makes to work/inoperative mechanical hook-up, its make connector work/inoperative operation in easily operation and without any need for instrument, can not damage any parts yet.Also noteworthy is that, if the technician has by mistake spurred clamping carrier 7, the fiber optic cables that are connected to the joints of optical fibre 20 can stand larger pulling force, this be because this moment pulling force be born by two 72a of locking ear on two Breech block 58a on the mechanical

splice assembly carriage

6 and 58b and the

clamping carrier

7 and 72b, rather than born by fiber optic cables.Therefore, the joints of optical fibre 20 are reversible (reversible), do not connect machine 20 and can not damage or destroy optical fiber, and still can provide firmly connector.Also merit attention and be, the reinforcement material of fiber optic cables make connector inoperative/can be not damaged in reciprocal (reverse) operation of working.

Figure 15 A-C shows three skeleton views of the connector shell 8 among Fig. 2.Figure 15 A sees top perspective in the past from the front end of connector shell 8, and shown in Figure 15 A, connector shell 8 has open front 93, receives the adapter (not shown) when being used for installing at the scene.Figure 15 B shows rear aperture 105 for see top perspective in the past from the rear end of connector shell 8, is used for receiving the rear end (seeing Fig. 3) of sleeve pipe 4.Figure 15 C is for seeing bottom perspective view in the past from the rear end of connector shell 8, shown in Figure 15 C, connector shell 8 comprises cavity 92 (having middle opening 106), is used for receiving and holding spring 10.Shown in Figure 15 B-C, to see over from the bottom of connector shell 8, rear aperture 105 and middle opening 106 are arranged on the two ends of cavity 92.Because mechanical splice assembly housing 5 needs just (fitly) by rear aperture 105, the inner periphery of the rear aperture 105 of connector shell 8 has identical geometric configuration by 90-degree rotation with open front 53 (seeing Fig. 5 A) on the mechanical splice assembly carriage 6.That is to say, if the after-opening 105 of connector shell 8 with respect to open front 53 90-degree rotations of mechanical splice assembly carriage 6, then the inner periphery of the open front 53 of the inner periphery of the after-opening 105 of connector shell 8 and mechanical splice assembly carriage 6 is overlapping.It should be noted that, owing to having the identical geometric configuration by 90 rotations, when mechanical splice assembly housing 5 was positioned at two different position of rotation, the open front 53 of the after-opening 105 of connector shell 8 and mechanical splice assembly carriage 6 can interact at two different moment and the fan-shaped protruding 7a of two couple on the mechanical splice assembly housing 5,37b and 38a, 38b.This structure is so that the after-opening 105 of connector shell 8 can be maintained on the mechanical splice assembly carriage 6 and the joints of optical fibre 20 stop rotatablely moving of mechanical splice assembly housing 5 after assembling at mechanical splice assembly housing 5.

With reference to Figure 16, it shows the cut-open view of the fiber optical cable assembly 10 among Fig. 1.As shown in figure 16, fiber optic cables 100 insert in the cable clamping part 51 of mechanical contiguous sets part carriage 6, and by these cable clamping part 51 clampings, simultaneously, fiber stub 24 inserts between continual-connecting-part 25a and the 25b, and by this continual-connecting-part 25a and 25b clamping.Optical fiber 102 in the fiber optic cables 100 is inserting under the guiding of groove 65 between continual-connecting-part 25a and the 25b, herein, and optical fiber 102 and fiber stub 24 adjacency, and be maintained between continual-connecting-part 25a and the 25b.Keep in the main part 50 of the mechanical contiguous sets part carriage 6 of mechanical splice assembly housing 5 insertions and by main part 50, and cam 3 is installed on the mechanical splice assembly housing 5.After spring 10 was put into connector shell 8, inserted in the connector shell 8 end of mechanical splice assembly 2, thereby spring 10 is installed on the end of mechanical splice assembly housing 5.After optical fiber 102 in fiber optic cables 100 was placed between continual-connecting-part 25a and the 25b, the cable clamping part 51 of mechanical splice assembly carriage 6 was inserted in the clamping carrier 7, presses together with two arms with cable clamping part 51.As shown in figure 16, guard shield 9 is used for holding main part 50, mechanical splice assembly 2, connector shell 8 and the spring 10 of mechanical splice assembly carriage 6.Shown in Figure 11 B, the opening 107 of guard shield 9 receives the adapter (not shown) when being used for installing at the scene.As shown in figure 16, connector shell 8 provides the linkage function according to the SC standard, and spring 10 provides biasing force between assembly housing 5 and the connector shell 8 continuing.

With reference to the accompanying drawings, the technician can carry out connector assembling operation according to following illustrative steps:

As shown in Figure 3, the technician inserts two continual-connecting-

part

25a and 25b in the mechanical contiguous sets part housing 5, and the fiber stub 24 on the sleeve pipe 4 is inserted between two continual-connecting-part 25a and the 25b;

Then the technician puts into spring 10 cavity 92 of the connector shell 8 shown in Figure 15 C;

Subsequently, the technician inserts in the guard shields 9 by the open rearward end 81 of guard shield 9 connector shell 8 and mechanical splice assembly carriage 6 successively and arrives such position: in this position, the cavity 52 of mechanical splice assembly carriage 6 (shown in Fig. 5 A) aligns with window 82 (shown in Figure 11 A) on the guard shield 9;

Thereafter, the technician passes the cavity 52 that window 82 on the guard shield 9 is put into mechanical splice assembly carriage 6 with cam 3 with its off-position;

With the fan-shaped projection 37a of two couple on the mechanical

splice assembly housing

5,37b and 38a, 38b is with after the after-opening 105 of connector shell 8 suitably aligns, the technician further inserts the rear end of mechanical splice assembly housing 5 in the open front 93 of connector shell 8, and the rear aperture 105 (shown in Figure 15 B) of passing spring 10 and connector shell 8, and the gap that connector shell 8 and mechanical splice assembly housing 5 is separated 2mm, then with mechanical splice housing 5 90-degree rotation in the counterclockwise direction, with with two couples of fan-shaped

projection

37a, 37b and 38a, 38b suitably aligns with the open front 53 of mechanical splice assembly carriage 6, next continues to insert mechanical contiguous sets part housing 5 and makes it pass the open front 53 (shown in 5A) of mechanical splice assembly carriage 6; And

At last, the technician rotates clockwise 90 degree with mechanical splice assembly housing 5, so that the protruding 54a on the mechanical

splice assembly carriage
