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 fixing of the reinforcing wire 703 in the utility model is realized by extrusion, and the rotation and fastening are not needed, so the twisting risk of the reinforcing wire and the optical fiber in the optical cable fastening process can be avoided; in addition, as shown in fig. 6, since the reinforcing wire 703 is pressed in the pressing groove 101b by the pressing member 200, the reinforcing wire 703 forms multiple bends at the bottom and top edges of the pressing groove 101b, so that the tensile strength of the reinforcing wire 703 after being fixed is greatly increased, and the reinforcing wire 703 cannot be released under the limit and the pressure of the peripheral clasping member 400.

Each extrusion strip 202 can be embedded into the corresponding pressing groove 101b, and press the reinforcing thread 703 part covered on the pressing groove 101b into the corresponding groove, so that the matching relationship between the pressing assembly 200 and the plurality of pressing grooves 101b in this embodiment increases the bending point of the reinforcing thread 703, and increases the tensile strength of the reinforcing thread 703 after being fixed.

Further, as shown in fig. 3, the pressing edge 201 in this embodiment is a step surface formed by recessing the outer edges of the two sides of the pressing assembly 200, and when the pressing assembly 200 is fastened around the outer periphery of the tailstock 101, the step surface as the pressing edge 201 is located right at the outer periphery of the unlocking section 101a, so that when the unlocking assembly 300 is pushed into the unlocking section 101a, the end of the upright 301 can touch the step surface and press the pressing assembly 200.

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 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 detachable optical cable fastening device further comprises a tail sleeve 500 for protecting the optical cable at the tail of the holding assembly 400, and also can perform a transverse restraining and limiting function on the embedded fixation 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 400, so that the tail sleeve 500 can pass through the inside of the holding assembly 400 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 400 and the tail sleeve 500 does not need to be considered.
