Third, as shown in fig. 10, one ends of the winding ring 201 and the fixing ring 202 are connected to the outside of the tailstock 101 through the folding-resistant plate 205, and the other ends can be covered on the periphery of the tailstock 101 through the respective turning covers. The pressing assembly 200 is preferably an integrally formed plastic member. Of course, in this embodiment, the structure of the pressing assembly 200 can also be considered as: a transverse spacing groove C is formed in the single pressing member 200, and is divided into two parts, so that the pressing member 200 is integrally divided into two halves to form a winding ring 201 at the front and a fixing ring 202 at the rear. During installation, the winding ring 201 on the side of the tailstock 101 may be turned over and covered in the first pressing groove 101a-1, and then the fixing ring 202 on the side of the tailstock 101 and behind the winding ring 201 may be turned over and covered in the second pressing groove 101a-2, so as to complete the installation of the pressing assembly 200 on the tailstock 101.

Referring to 11(a) to 11(c) in fig. 11, the method for fastening the reinforcing wire 703 by the reinforced cable fastening device in this embodiment comprises the steps of:

s2: threading the prepared optical cable into the optical fiber field connector, tensioning the reinforcing wire 703 forwards and covering the tailstock 101, and pressing the section of the reinforcing wire 703 covered on the first pressure groove 101a-1 into the first pressure groove 101a-1 through the winding ring 201;

Referring to 11(a) to 11(d) in fig. 11, the method for fastening the reinforced cable fastening device to the reinforcing wire 703 may further include the following steps:

s2: threading the prepared optical cable into the optical fiber field connector, tensioning and covering the reinforcing wire 703 on the tailstock 101, and pressing the reinforcing wire 703 section covered on the first pressing groove 101a-1 into the first pressing groove 101a-1 through the winding ring 201;

s4: cutting off the excess reinforcing wire 703 and leaving a part of the reinforcing wire 703, pulling back the reinforcing wire 703 forwards again in the reverse direction, and making the reinforcing wire 703 form a third covering on the tailstock 101, and then sleeving the clasping assembly 300 on the peripheries of the winding ring 201 and the fixing ring 202 to limit the pressing assembly 200 and fix the reinforcing wire 703, thereby completing the optical cable fixing and terminating (the step S4 may also be that the excess reinforcing wire 703 is cut off, a part of the reinforcing wire 703 is left, the clasping assembly 300 is pushed forwards, and the reinforcing wire 703 is turned back forwards and sleeved on the periphery of the combination of the pressing assembly 200 and the tailstock 101 by the clasping assembly 300 through pushing and friction of the clasping assembly 300 on the tail end of the remaining reinforcing wire 703, thereby realizing the limiting of the pressing assembly 200 and the fixing of the reinforcing wire 703, and completing the optical cable fixing and terminating).

The technical solutions in the prior art (thread pair compression mode), example 1 (single-layer compression mode), example 2 (single-layer compression mode), and example 3 (multi-layer compression mode) are now integrated to perform a tensile test on the fastening effect of the reinforcing wire, so that the following experimental data in table 1 can be obtained:

table 1 comparative table of tensile strength of reinforced cable:

note: the thread pairs in table 1 are prior art; plastic single snap ring representation: the pressing component 200 is made of plastic and has an integrated single-ring structure; plastic wound snap ring representation: the pressing component 200 is made of plastic and comprises a double-ring structure of a winding ring and a fixing ring; metal single snap ring representation: the pressing component 200 is made of metal and has an integrated single-ring structure; metal wound snap ring representation: the pressing member 200 is made of metal and includes a double ring structure of a winding ring and a fixing ring.

For the fixing scheme of the optical cable reinforcing wire, the defects of the existing screw thread pair fastening scheme are as follows: the clearance of the thread pair is small, so that when the thread is screwed down, the optical cable reinforcing wire can rotate along with the nut sleeve, the reinforcing wire is further wound and drives the optical fiber to twist together, and the bending loss of the optical fiber is increased and even the optical fiber is broken; if this phenomenon is avoided, the thread pair clearance needs to be increased, and the tensile strength is poor even if the reinforcing wire is less wound, and the tensile strength of the optical cable cannot reach 50N.

The utility model discloses a winding ring 201 turns over a winding and extrudes the enhancement line 703, and solid fixed ring 202 will turn over the enhancement line 703 of rolling over and press in the indent C of tailstock 101 thoughtlessly, hold subassembly 300 at last and push away to turn over a enhancement line 703 end once more. Therefore, the ultra-high fastening of the optical cable reinforcing wire 703 is realized through the tightening and winding of the winding ring 201, the folding and clamping of the fixing ring 202, the frictional resistance between the reinforcing wires 703 and the pressure of the clasping assembly 300, so that the tensile resistance reaches over 90N. Furthermore, the utility model discloses a winding ring 201 and the components of a whole that can function independently design of solid fixed ring 202 realize the winding and the fixed substep implementation of enhancement line 703, realize that optical cable enhancement line 703 is simple and direct firm to be fastened fast, guaranteed that indoor optical cable 700 one-tenth end manufacturing process is simple and convenient, easy dismounting, work efficiency is high, does not need special frock, and overall structure fastening is reliable.

Example 4

As shown in fig. 12 and 13, the present embodiment is based on embodiment 1 or embodiment 3, but differs therefrom in that: the reinforced optical cable fastening device in this embodiment further includes an unlocking assembly 400 for detaching the pressing assembly 200 from the tailstock 101, as embodiment 4 of the present invention; and in this embodiment, the pressing assembly 200 is a separate member, independent from the tailstock 101, and assembled by a field.

The following of this embodiment is specifically described by taking the technical solution based on embodiment 1 as an example:

the unlocking assembly 400 includes a pair of oppositely disposed posts 401, the two posts 401 preferably being a pair of plate-like structures parallel to each other, and a slot 402 being formed between the two posts 401. Preferably, the two posts 401 are connected together at one end by connector plates 403 to form a one-piece structure with a U-shaped transverse projection, and at the other end they form an outwardly open notch 402.

The pressing assembly 200 is preferably made of a ductile metallic elastic material, such as beryllium bronze or stainless steel, and the pressing assembly 200 includes a plurality of extruded strips T and a rod structure L integrally formed at an end of each extruded strip T. The pressing member 200 has pressing edges 206 formed on both outer edges thereof corresponding to the ends of the pillars 401.

The transverse width of at least part of the sections on the tailstock 101 is not greater than the width of the notch 402, so as to form an unlocking section 101b, so that the unlocking section 101b can be embedded into the notch 402 of the unlocking assembly 400, and the pressing assembly 200 can be ejected out of the tailstock 101 by the pressing of the tail end of the upright 401 to the pressing edge 206, thereby realizing the dismounting of the pressing assembly 200. It should be noted that: the arc-shaped profile of the pressing member 200 is an arc (preferably a major arc) which can be fixed to the periphery of the tailstock 101 by snap-in engagement, and the pressing edge 206 of which can extend to the periphery of the unlocking section 101b so as to facilitate the contact pressing of the end of the pillar 401.

Preferably, the pressing edge 206 in this embodiment is a stepped surface formed by recessing the outer edges of the two sides of the pressing member 200. The unlocking section 101b is a pair of parallel planes formed by the tailstock 101 being recessed inward, and the perpendicular distance between the pair of parallel planes corresponds to the width of the slot 402. When the pressing assembly 200 embraces the periphery of the tailstock 101, the step surface of the pressing edge 206 extends to the periphery of the unlocking section 101 b. When the unlocking assembly 400 is inserted transversely along its plane at the unlocking section 101b, the end of the upright 401 is able to press the pressing edge 206 of the pressing assembly 200 and eject the pressing assembly 200 out of the tailstock 101.

Further, as shown in fig. 14, a stop block 302 is disposed on an inner sidewall of the clasping assembly 300 and is engaged with the unlocking section 101b, and the stop block 302 is a convex block-shaped structure. Because the unlocking sections 101b are a pair of planes parallel to each other formed by inward recession of the tailstock 101, when the clasping assembly 300 is sleeved on the periphery of the tailstock 101, the limiting block 302 can be attached to the corresponding unlocking section 101b to form a limiting position, so as to prevent the clasping assembly 300 from rotating in the circumferential direction.

Further, as shown in fig. 14, a clamping groove 101c is formed in the periphery of the tailstock 101, the clasping assembly 300 is made of an elastic material (such as rubber), and a clamping platform 301 corresponding to the clamping groove 101c is disposed on an inner side wall of the clasping assembly 300, and when the clasping assembly 300 is sleeved on the periphery of the tailstock 101, the clamping platform 301 can be buckled into the clamping groove 101c, so that the clasping assembly 300 can be fixed on the periphery of the tailstock 101 and the pressing assembly 200.

Example 5

As shown in fig. 15 to 20, the present embodiment is based on any one of embodiments 1 to 4, but the difference is that: the connecting base 100 in this embodiment further includes a positioning member 102, one end of the positioning member 102 is connected to the tail seat 101, the other end extends rearward along the longitudinal direction, and the extending end is used for fixing the sheath 704.

The front end of the positioning member 102 can be integrally injected into the tailstock 101, and can also 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.

In the present embodiment, 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 outer sheath 704 of the indoor optical cable 700; cantilever 102a is a longitudinally extending, strip-like structure, preferably curved in cross-section with a convex curvature.

In practice, one end of the stripped optical cable may be sequentially passed out of the clasping assembly 300 and the tailstock 101, the outwardly extended tight-buffered layer 702 and the bare optical fiber 701 are fixed by the head body of the fiber field connector, the outer sheath 704 is fixed in the fixing position G of the fixing head 102c, the reinforcing wire 703 is tightened and covered on the tailstock 101, the pressing assembly 200 is pressed into the pressing groove 101a of the tailstock 101, and finally the clasping assembly 300 is sleeved on the pressing assembly 200 and the periphery of the tailstock 101 to form the limiting and fixing.

Strenghthened type optical cable is set up the device and can be realized guaranteeing that indoor optical cable becomes to hold the manufacture process simple and convenient to fix fast to enhancement line 703 and crust 704, easy dismounting, work efficiency is higher, does not need special frock, and overall structure fastening is reliable. Because the positioning member 102 is made of elastic material with plasticity, after the indoor optical cable 700 is fixed on the optical cable fastening device, the indoor optical cable 700 can be held together with the positioning member 102 and can be subjected to adaptive bending deformation according to the field wiring condition and the wiring direction, or the positioning member 102 can be directly bent artificially, so that the indoor optical cable exceeds the elastic limit and undergoes permanent plastic deformation, and the positioning member 102 in a required bending or moving mode is obtained.

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 101e forms a flared section 101e-1, the inner side wall of the flared section 101e-1 forms a flared shape which is open backwards, and the inner diameter of the outer end is larger than the inner diameter of the inner end to form a conical surface. The front end of the opening section 101e-1 is recessed inwards to form a fixing cavity 101e-2 for fixing the connector 102 b; the connection head 102b can be inserted forward from the flared section 101e-1 and fixed in the fixing cavity 101e-2, and the fixing head 102c can project backward out of the longitudinal channel 101 e.

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 101e-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 101e-1, the connector can be squeezed to shrink and deform, and then can smoothly slide through the opening section 101e-1 and enter the fixing cavity 101 e-2. After entering the fixed cavity 101e-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 101e-2, and cannot move longitudinally due to being limited by the step surfaces at the front and rear ends of the fixed cavity 101e-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, wherein the locking member 102c-3 extends into the fixing position G to perform a final fixing function on the outer skin 704 embedded in the fixing position G. The locking element 102c-3 may be a protruding structure, a knife-like structure, or a pointed structure inside the securing location G that is capable of extending partially into the securing location G, such that when the sheath 704 is embedded within the securing location G, the locking element 102c-3 is capable of partially, cutting or piercing into the sheath 704 to achieve longitudinal retention and final securing of the sheath 704.

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 704 is completely inserted into the fixing position G, the locking member 102c-3 can cut into the outer skin 704 to limit the longitudinal sliding of the outer skin 704, 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 reinforced optical cable fastening device further comprises a tail sleeve 500 for protecting the optical cable at the tail of the holding assembly 300, and the tail sleeve can also play a role in transversely restraining and limiting the embedding and fixing of the outer skin 704 in the fixing position G. Specifically, the tail sleeve 500 has a limiting chamber 501 with two through ends, and the peripheral contour of the fixing head 102c is matched with the inner side wall of the limiting chamber 501. After the sheath 704 is embedded into the fixing portion G, the limiting chamber 501 can be sleeved on the periphery of the fixing head 102c to form a coating, so that the sheath 704 and the fixing head 102c are firmly fixed, and meanwhile, the clamping force change caused by hardness and softness of the sheath 704 when the indoor optical cable 700 is changed in cold and hot temperatures is avoided.

Further, a pressing strip 501a is arranged on the inner side wall of the limiting cavity 501, the pressing strip 501a is matched with the inner side distance between a pair of clamping columns 102c-2 (namely clamping claws) which are opposite to each other, and the pressing strip 501a can be embedded into the openings of the clamping claws after the limiting cavity 501 is sleeved on the periphery of the fixing head 102c, so that the transverse extrusion of the outer skin 704 is realized, and the compactness and stability of the outer skin 704 fixed in the fixing position G are ensured.

Further, a wire gathering groove 502 is arranged at the front end of the tail sleeve 500, and the wire gathering groove 502 is open outwards. The exposed reinforcing wire 703 is straightened and then constrained in the wire gathering groove 502, and has a positioning effect on the position of the reinforcing wire 703.

Furthermore, the tail sleeve 500 is provided with an observation window 503 which can be communicated to the limiting cavity 501. The viewing window 503 is a through-going feature on the boot 500 and is directly opposite any section of the upjacket layer 702. After the optical cable is fixed by the constructor, the leakage detection red light in the bent optical cable can be checked through the observation window 503 to determine the leakage degree, so as to preliminarily judge the approximate bending degree of the tight cladding layer 702 and the fixing quality of the optical cable. In another embodiment, the tail sleeve 500 is made of a transparent or translucent material, such as a conventional transparent plastic, a translucent PC material, etc., and can directly observe the light leakage inside the tail sleeve 500 instead of the observation window 503.

Further, the front end of the inner side wall of the limiting chamber 501 is provided with an anti-release ring segment 504 corresponding to the clamping column 102c-2, and the inner diameter of the anti-release ring segment 504 is smaller than the maximum distance between the peripheries of the clamping jaws, so that after the limiting chamber 501 is sleeved on the periphery of the fixing head 102c, the anti-release ring segment 504 can be placed on the front side surface of the clamping jaws, the limiting of the tail sleeve 500 is realized, and the tail sleeve cannot be released backwards.

Further, the maximum outer diameter of the tail sleeve 500 is not larger than the minimum inner diameter of the holding assembly 300, so that the tail sleeve 500 can pass through the inside of the holding assembly 300 without hindrance, and when the indoor optical cable 700 is used for fiber penetrating installation, the problem of sequential fiber penetrating of the holding assembly 300 and the tail sleeve 500 does not need to be considered.

Example 6

Referring to fig. 1 and 21, this embodiment provides an optical fiber connector based on embodiment 5, which uses the reinforced cable securing device of embodiment 5 to fix the reinforcing wire 703 and the outer cover 704 of the indoor optical cable 700.

As shown in fig. 21, the optical fiber connector includes the connection receptacle 100, the pressing member 200, the clasping member 300, and the boot 500 of embodiment 5, and further includes a connector body 600 and an indoor optical cable 700.

Specifically, the connector body 600 may adopt a head structure of an existing optical fiber connector, such as a head body in an optical fiber field connector, and can be connected to the front end of the tailstock 101.

The indoor optical cable 700 may be an existing indoor optical cable, which includes a bare fiber 701, a tight-buffered layer 702, a reinforced wire 703 and an outer sheath 704, which are wrapped layer by layer from outside to inside, and the four are exposed layer by layer from outside to inside. The exposed outer skin 704 is passed forward and fixed in the fixing position G; the end of the exposed reinforcing wire 703 is pressed in the pressing groove 101a on the tailstock 101 by the pressing component 200; the bare fiber 701 with the exposed upjacket layer 702 and its inner layer is threaded forward into the interior of the connector body 600.

The method for manufacturing the end of the indoor optical cable by using the optical fiber connector comprises the following steps:

firstly, one end of the optical cable passes through the clasping component 300 and the tail sleeve 500;

secondly, preparing an optical cable by stripping: peeling the outer end of the outer skin 704, straightening and turning over the reinforcing wire 703, peeling the outer end of the tight cladding 702, and cutting the bare fiber at a fixed length;

thirdly, one end of the prepared optical cable passes through the connecting seat 100 and is inserted into the connector main body 600, and the tight cladding layer 702 and the bare fiber 701 are positioned through the connector main body 600;

fourthly, the outer skin 704 is embedded into the fixing position G of the fixing head 102c, and the locking piece 102c-3 can cut into the outer skin 704 to realize the fixation of the outer skin 704;

fifthly, the connector body 600 fixes the tight cladding layer 702 and the bare fiber 701;

sixthly, the tail sleeve 500 is pushed forwards, so that the fixing head 102c slides into the limiting chamber 501, and the fixing head 102c is held tightly and limited;

seventhly, the reinforcing wire 703 is pulled forward to be led out of the wire gathering groove 502, covered on the pressure groove 101a of the tailstock 101, and pressed into the pressure groove 101a of the tailstock 101 through the pressing assembly 200 (here, the pressing assembly 200 can refer to the step S2 in the

embodiment

1 or 2, and also refer to the steps S2 to S3 in the embodiment 3 for pressing and fixing the reinforcing wire 703);

eighthly, cutting off redundant reinforcing wires 703 (or leaving a part of reinforcing wires 703), and pushing the enclasping component 300 forward, so that the enclasping component 300 is tightly sleeved on the periphery of the combination of the pressing component 200 and the tailstock 101, the limitation of the pressing component 200 and the fixation of the reinforcing wires 703 are realized, and the fixation and end forming of the optical cable are completed. When a part of the reinforcing wire 703 remains, the holding assembly 300 is pushed forward, so that the reinforcing wire 703 is folded back forward and is tightly sleeved on the periphery of the combination of the pressing assembly 200 and the tailstock 101 by the holding assembly 300, the limiting of the pressing assembly 200 and the fixing of the reinforcing wire 703 are realized, and the fixing and terminating of the optical cable are completed.

Based on above-mentioned step can obtain the fiber connector of quick preparation in scene, because the utility model provides a setting element 102 adopts the elastic material that has plasticity, therefore fiber connector assembles the completion back, and cantilever 102a can carry out adaptability ground swing according to the direction of laying wire crooked, also can be through artificial direct with cantilever 102a along walking the crooked design of line direction, make it produce moulding deformation, solved like this because the connector overlength, the optical cable damage of buckling that causes with ODF door counterbalance.

In addition, after the manufactured optical fiber connector is installed on an optical port, when a constructor bundles an optical cable according to the routing direction, the cantilever 102a can be bent and deformed, so that the optical fiber therein is protected, and meanwhile, the occupied space is reduced. Of course, the metal cantilever 102a may be artificially deformed to shape the bending direction.
