The indoor optical cable 500 comprises a bare fiber 501, a tight cladding layer 502, a reinforcing wire 503 and an outer sheath 504 which are wrapped layer by layer from outside to inside; prior to the termination of the optical cable, the end of the indoor optical cable 500 is stripped (including stripping the outer ends of the sheath 504 and the upjacket layer 502) so that the reinforcing wires 503 are exposed outside the sheath 504 at the end of the upjacket layer 502 and the upjacket layer 502 at the end of the bare optical fiber 501. The reinforcing wire 503 and its outer sheath 504 are secured by a modular cable securing device, while the upjacket layer 502 and its inner bare fiber 501 are secured by threading into the head body of the fiber optic field connector.

The modular cable securing apparatus includes a connector housing 100 and a compression assembly 200.

The tailstock 101 may be a hollow sleeve-shaped structure, the front end of which is inserted into the head body of the fiber field connector to be fixed, and the rear end of which is connected to the compressing assembly 200. The front of the utility model corresponds to the head main body direction of the optical fiber field connector, i.e. the penetrating direction of the indoor optical cable 500; "rear" corresponds to the rear direction of the indoor optical cable 500. The outer side wall of the tail seat 101 is provided with a connecting part 101a for matching and connecting with the compressing component 200, and the interior of the tail seat 101 is provided with a longitudinal channel 101b with two through ends. The connecting portion 101a may be an external thread, a slot or a hook.

The positioning member 102 is used for fixing the outer skin 504, and the front end of the positioning member can be integrally injected into the tailstock 101, or can be fixed on the tailstock 101 through later assembly; the rear end of which extends longitudinally outwardly. When the positioning element 102 and the tailstock 101 are assembled, the tailstock 101 and the positioning element 102 are independent parts, and can be connected and fixed by assembling the tailstock 101 and the positioning element, so as to form a complete connecting seat 100.

The positioning member 102 is made of an elastic material, preferably a metal spring plate with plasticity, such as stainless steel or beryllium bronze with elasticity. Specifically, the positioning member 102 includes a cantilever 102a extending longitudinally, a connecting head 102b fixed to one end of the cantilever 102a, and a fixed head 102c fixed to the other end of the cantilever 102 a. The connector 102b can be assembled and connected with the tailstock 101; the fixing head 102c has a longitudinally through fixing position G inside for embedding and fixing the sheath 504 of the indoor optical cable 500; cantilever 102a is a longitudinally extending, strip-like structure, preferably curved in cross-section with a convex curvature.

The compressing assembly 200 includes a ring-shaped connecting section 201, and the connecting section 201 is detachably connected to the periphery of the connecting portion 101a of the tailstock 101 and can generate compression therewith. The inner side wall of the connecting section 201 may be provided with a complementary structure such as an internal thread, a hook or a slot for engaging with the connecting portion 101 a. When one end of the exposed reinforcing wire 503 is straightened and covered on the connecting part 101a, the connecting section 201 can press the reinforcing wire 503 between the connecting section 201 and the connecting part 101a through the connection with the connecting part 101a, so that the reinforcing wire 503 can be fixed once.

In practice, one end of the stripped optical cable may be passed forward through the connecting section 201 and the tail block 101 in sequence, and fixed to the outwardly extending tight-buffered layer 502 and the bare optical fiber 501 through the head body of the optical field connector, and then the sheath 504 may be inserted and fixed into the fixing position G of the fixing head 102c, and finally the reinforcing wire 503 may be tightened and pressed between the connecting section 201 and the connecting section 101a through the connecting section 201.

In summary, the combined optical cable fastening device can realize quick fixation of the reinforcing wire 503 and the outer skin 504, ensure simple and convenient manufacturing process of the finished end of the indoor optical cable, is convenient to disassemble and assemble, has high working efficiency, does not need a special tool, and has a firm and reliable integral structure; in addition, the combined optical cable fastening device has few parts and can be independently disassembled for reuse. Because the positioning piece 102 is made of elastic material with plasticity, after the indoor optical cable 600 is fixed on the optical cable fastening device, the indoor optical cable can be embraced with the positioning piece 102 and can be subjected to adaptive bending deformation according to the field wiring condition and the wiring direction, or the positioning piece 102 can be directly bent artificially, so that the indoor optical cable exceeds the elastic limit and is subjected to permanent plastic deformation, and the positioning piece 102 in a required bending or moving mode is obtained.

Preferably, the connecting section 201 is detachably connected to the outer periphery of the connecting portion 101a of the tailstock 101 by means of a screw. Namely: the connecting part 101a is provided with an external thread, the connecting section 201 is sleeved on the periphery of the connecting seat 100, and the inner side wall of the connecting section is provided with an internal thread matched with the external thread; the connecting section 201 and the connecting part 101a are detachably connected through matching of threads.

Further, the rear end of the tailstock 101 is provided with a tapered surface 101c, and the compressing assembly 200 further includes an extruding section 202 connected to the connecting section 201 and located at the rear end thereof, wherein the connecting section 201 and the extruding section 202 are integrally formed. The extruding section 202 may be a tapered tube having an inner diameter gradually decreasing from the end engaged with the connecting section 201 toward the rear. When the connecting section 201 is connected to the connecting section 101a of the tailstock 101, the pressing section 202 can press the tapered surface 101 c. Therefore, the reinforcing wire 503 introduced between the connecting section 201 and the connecting section 101a can be sandwiched between the pressing section 202 and the tapered surface 101c, so that the reinforcing wire 503 is doubly fixed and has a tensile resistance exceeding 40N.

Further, the rear portion of the compressing assembly 200 is provided with a bell mouth 203, and the flexible cantilever 102a passes through the bell mouth 203 and can swing within the bell mouth 203 to a certain extent.

Further, for realizing the assembly connection of the connector 102b on the tailstock 101, the utility model adopts the following technical scheme: the rear part of the longitudinal channel 101b forms an opening section 101b-1, the inner side wall of the opening section 101b-1 forms a trumpet shape which is opened backwards, the inner diameter of the outer end of the trumpet shape is larger than that of the inner end of the trumpet shape, and a conical surface is formed. The front end of the opening section 101b-1 is recessed inwards to form a fixing cavity 101b-2 for fixing the connector 102 b; the connection head 102b can be inserted forward from the flared section 101b-1 and fixed in the fixing cavity 101b-2, and the fixing head 102c can project backward out of the longitudinal channel 101 b.

Preferably, the connecting head 102b is an annular structure integrally formed at the end of the cantilever 102a and having a gap, and correspondingly, the fixing cavity 101b-2 is an annular groove matched with the outer diameter of the connecting head 102 b. Because the connector 102b is of an annular structure with a notch and has elasticity, when the connector is pushed inwards from the flared opening section 101b-1, the connector can be squeezed to shrink and deform, and then can smoothly slide through the opening section 101b-1 and enter the fixing cavity 101 b-2. After entering the fixed cavity 101b-2, the connector 102b released from the extrusion is restored to its original shape due to its elasticity and is expanded in the fixed cavity 101b-2, and cannot move longitudinally due to being limited by the step surfaces at the front and rear ends of the fixed cavity 101b-2, thereby achieving the fixation.

Preferably, the fixed head 102c includes a support plate 102c-1 at the rear end of the cantilever 102a and a pair of clamping posts 102c-2 symmetrically disposed at both sides of the support plate 102 c-1. The pair of the catching posts 102c-2 facing each other can form a set of catching jaws having openings and enclose the holding position G together with the supporting plate 102c-1, so that one or more catching jaws can be arranged in the supporting plate 102c-1 in the longitudinal direction. In the present invention, the fixing head 102c is integrally formed at the rear end of the cantilever 102 a.

Further, the fixing head 102c further comprises a locking member 102c-3 fixed to the inner side surface of the supporting plate 102c-1 and/or the clamping column 102c-2, and the locking member 102c-3 extends into the fixing position G to perform a final fixing function on the outer skin 504 embedded in the fixing position G. The locking member 102c-3 may be a protruding structure, a knife-like structure or a pointed structure inside the fixing location G that can extend partially into the fixing location G, so that when the sheath 504 is embedded into the fixing location G, the locking member 102c-3 can partially, incise or pierce into the sheath 504, achieving longitudinal restraint and final fixing of the sheath 504.

Preferably, the locking member 102c-3 is a male blade-like structure disposed on the inner side of the latch 102c-2 and is integrally formed with the latch 102 c-2. When the outer skin 504 is completely embedded into the fixing position G, the locking member 102c-3 can cut into the outer skin 504 to limit the longitudinal sliding of the outer skin 504, thereby achieving the fixing.

Similarly, the inner side of the plate 102c-1 may be provided with a locking element 102c-3, and the locking element 102c-3 may be a protruding or pointed structure on the inner side of the plate 102 c-1. In another embodiment, the support plate 102c-1 may be punched from the outside to the inside to form a hole, and since the punching process has a pressing and cutting edge friction to the metal plate, a sharp burr and a protrusion extending inwards can be formed on the punched hole edge, and the sharp burr and the protrusion can be directly regarded as the locking element 102c-3 on the support plate 102 c-1.

Further, the combined optical cable fastening device further comprises a tail sleeve 300, which is used for protecting the optical cable at the tail of the compression assembly 200 and can also play a role in transversely restraining and limiting the embedded fixation of the sheath 504 in the fixing position G. Specifically, the tail sleeve 300 has a limiting chamber 301 with two through ends, and the peripheral contour of the fixing head 102c is matched with the inner side wall of the limiting chamber 301. After the sheath 504 is embedded into the fixing position G, the limiting chamber 301 can be sleeved on the periphery of the fixing head 102c to form a coating, so that the sheath 504 and the fixing head 102c are firmly fixed, and meanwhile, the clamping force change caused by hardness and softness of the sheath 504 when the indoor optical cable 500 is changed in cold and hot temperatures is avoided.

Further, a pressing strip 301a is arranged on the inner side wall of the limiting cavity 301, the pressing strip 301a is matched with the inner side distance between a pair of clamping columns 102c-2 (namely clamping jaws) which are opposite to each other, the pressing strip 301a can be embedded into the openings of the clamping jaws after the limiting cavity 301 is sleeved on the periphery of the fixing head 102c, so that the transverse extrusion on the outer skin 504 is realized, and the compactness and the stability of the outer skin 504 fixed in the fixing position G are ensured.

Further, a wire gathering groove 302 is arranged at the front end of the tail sleeve 300, and the wire gathering groove 302 is opened outwards. The exposed reinforcing wire 503 is constrained in the wire gathering groove 302 after being pulled, and has a positioning effect on the position of the reinforcing wire 503; in addition, the wire gathering groove 302 can improve the torsion resistance of the connecting section 201 in the rotating process, and avoids the extra damage of the optical cable caused by the winding of the reinforcing wire 503 and the optical cable caused by the rotating and tightening of the connecting section 201.

Furthermore, the tail sleeve 300 is provided with an observation window 303 which can be communicated to the limiting cavity 301. The viewing window 303 is a through-going feature on the boot 300 and is directly opposite any section of the upjacket layer 502. After the optical cable is fixed by constructors, the red light leaked from the bent optical cable can be checked through the observation window 303, and the leakage degree can be determined, so that the approximate bending degree of the tight coating layer 502 and the fixing quality of the optical cable can be preliminarily judged. In another embodiment, the tail sleeve 300 is made of a transparent or semitransparent material, such as a conventional transparent plastic, a semitransparent PC material, or the like, and can directly observe the light leakage inside the tail sleeve 300 instead of the observation window 303.

Furthermore, the front end of the inner side wall of the limiting chamber 301 is provided with an anti-release ring segment 304 corresponding to the clamping column 102c-2, and the inner diameter of the anti-release ring segment 304 is smaller than the maximum distance between the peripheries of the clamping jaws, so that after the limiting chamber 301 is sleeved on the periphery of the fixing head 102c, the anti-release ring segment 304 can be placed on the front side surface of the clamping jaws, the limiting of the tail sleeve 300 is realized, and the tail sleeve cannot be loosened backwards.

Further, the maximum outer diameter of the tail sleeve 300 is not larger than the minimum inner diameter of the compression assembly 200, so that the tail sleeve 300 can pass through the interior of the compression assembly 200 without hindrance, and the problem of successive fiber passing of the compression assembly 200 and the tail sleeve 300 is not required to be considered when the indoor optical cable 500 is installed in a fiber passing mode.
