Examples:
referring to fig. 1 to 3, the protection device for a scalable high core number optical cable subunit 5 according to the preferred embodiment of the present application includes at least one installation groove 1, wherein the installation groove 1 is used for placing the optical cable subunit 5, and the optical cable subunit 5 is regularly arranged inside the installation groove 1; the number of the protection hoses 2 is corresponding to that of the optical cable subunits 5, and the protection hoses 2 are sleeved on the periphery of the optical cable subunits 5 and pass through the installation groove 1; and a protective sleeve 3, one end of the protective sleeve 3 is wrapped on the periphery of the cable 4, and the other end of the protective sleeve is wrapped on the periphery of the mounting groove 1, so as to isolate the optical cable subunit 5 between the mounting groove 1 and the cable 4 from the outside.
When the conventional optical cable subunit 5 performs separation work, the external protection and the integral protection of the optical cable subunit 5 work, so that the outer diameter of the optical cable subunit 5 at the opening of the cable 4 is increased, the bending radius at the transition position of the optical cable subunit is too small, the optical cable subunits 5 are mutually extruded, and the optical cable subunit 5 with larger bending rate easily causes attenuation in the communication transmission process, thereby affecting the transmission quality and the service life of the optical fiber.
The protection device of the expandable large-core-number optical cable subunit 5 is arranged to enable all the optical cable subunits 5 to be orderly arranged and pass through the installation groove 1, the protection hose 2 is arranged outside the optical cable subunit 5, the protection sleeve 3 is arranged between the installation groove 1 and the cable 4, the optical cable subunit 5 is isolated from the outside through the protection sleeve 3, the protection sleeve 3 is arranged to form secondary protection on the optical cable subunit 5, and the sleeving area of the protection hose 2 can be prolonged after the optical cable subunit 5 comes out of the port of the cable 4, so that the optical cable subunit 5 is smoothly expanded, and the problem that the bending radius of the excessive position of the optical cable subunit 5 is too small is avoided.
Further, as a preferred embodiment of the present application, the plurality of installation grooves 1 are provided, the plurality of installation grooves 1 can be spliced with each other in sequence, and the splicing direction of the plurality of installation grooves 1 is perpendicular to the placing direction of the optical cable subunit 5. When the optical cable subunits 5 are in butt joint with a machine room, an optical cross box and the like, the cables 4 with different cores are provided with different numbers of the optical cable subunits 5, and the core number difference between the different cables 4 is large, so that the adoption of a protection device is often insufficient for various requirements. The installation grooves 1 are thus arranged in a mutually spliced manner, the splicing direction of the plurality of installation grooves 1 being perpendicular to the placement direction of the optical cable subunits 5, so that each installation groove 1 forms a stacked placement area for accommodating cables 4 of different optical cable subunit 5 arrangements, such as ribbon cables or round cables. Preferably, the splicing form of the mounting grooves 1 is variable, the mounting grooves 1 can be made into a sheet shape, the mounting grooves 1 are stacked and spliced, the mounting grooves 1 can be made into a strip shape, the mounting grooves 1 are vertically spliced side by side, or other forms such as oblique splicing and the like are arranged.
Further, the number of the accommodating optical cable subunits 5 in the installation groove 1 is one of 4, 6, 8, 12, 24 or 48. When the protection device is used, the accommodating quantity of the installation grooves 1 needs to be selected and adjusted according to the quantity of the optical cable subunits 5 in the cable 4 so as to achieve the optimal fixing effect. The installation grooves 1 with different accommodating quantity can be mutually combined and configured to form the installation grooves 1 with different shapes so as to be matched with a belt cable or a round cable and the like, for example, when aiming at the belt cable, the installation grooves 1 are spliced to form a square structure so as to correspond to the optical cable subunits 5 one by one; when aiming at a round cable, the mounting groove 1 is spliced into a round-like structure with less two ends and wide middle; so that the optical cable subunit 5 does not change the extending direction of the optical cable subunit 5 greatly when being connected to the mounting groove 1, so as to reduce the bending radius of the optical cable subunit 5 and ensure that the optical cable subunit 5 is not bent and damaged. Alternatively, the number of the installation grooves 1 to be accommodated in the optical cable subunits 5 in the present application may be other than the number described above, and the accommodated number may be adjusted according to the actual number of cores of the cable 4. Likewise, the actual size, dimensions, etc. of the mounting groove 1 may be adjusted according to the outer diameter of the cable subunit 5, the outer diameter of the protection hose 2, etc.
Further, as a preferred embodiment of the present application, the mounting groove 1 includes two oppositely disposed first wall surfaces 101 and second wall surfaces 102, wherein at least one clamping interface 103 is formed on the first wall surface 101, a number of clamping pieces 104 corresponding to the clamping interfaces 103 are formed on the second wall surface 102, and the clamping pieces 104 of adjacent mounting grooves 1 are correspondingly clamped in the clamping interfaces 103 of another mounting groove 1. In order to accommodate the cables 4 of the different numbers of optical cable subunits 5, the installation groove 1 is arranged in a spliced form, and the corresponding connection of the connected installation groove 1 is realized by arranging the clamping interfaces 103 on the first wall surface 101 of the installation groove 1 and correspondingly arranging the clamping pieces 104 on the second wall surface 102. The quick splicing of the optical cable subunits 5 during installation and wearing can be realized in a simple clamping mode, meanwhile, the clamping piece 104 correspondingly stretches into the clamping interface 103 to press the protection hose 2, so that the optical cable subunits 5 in the installation groove 1 are fixed, and the ordered arrangement of the optical cable subunits 5 is ensured. Alternatively, the number of the clip members 104 and the clip interfaces 103 may be set in plural forms, thereby achieving stable connection of the adjacent mounting grooves 1.
Further, as a preferred embodiment of the present application, a pressing piece 105 is provided in the installation groove 1 of the present application, and the pressing piece 105 is provided parallel to the first wall surface 101 for pressing the protection hose 2 when the clip member 104 is inserted into the clip port 103. In order to facilitate rapid progress of the clamping work and ensure connection stability of the adjacent installation grooves 1, the end of the clamping member 104 needs to be set to be convex in front, so that the clamping member 104 easily presses the protection hose 2 at the clamping position, and further presses the optical cable subunit 5. Meanwhile, the clip 104 cannot complete the crimping work for all the protection hoses 2. Therefore, the installation groove 1 is provided with a pressing sheet 105 structure parallel to the first wall surface 101, the pressing sheet 105 is pressed by the clamping piece 104, and then all the protection hoses 2 in the installation groove 1 are pressed by the pressing sheet 105, so that the fixing work of the optical cable subunit 5 in the installation groove 1 is completed.
Further, as a preferred embodiment of the present application, the sum of the distance by which the clip 104 is crimped to the pressing piece 105 and the outer diameter of the protection hose 2 is larger than the distance between the first wall surface 101 and the second wall surface 102. In the crimping process of the clamping piece 104, the stability of the optical cable subunit 5 needs to be ensured, so when the adjacent installation grooves 1 are in clamping connection, the pressing piece 105 needs to apply pressure to the protection hose 2, so that the protection hose 2 is fixed, and the stability of the optical cable subunit 5 is realized. For this reason, the sum of the distance by which the clip 104 is crimped to the press piece 105 and the outer diameter of the protection hose 2 must be larger than the distance between the first wall 101 and the second wall 102. After the clamping piece 104 is pressed into the mounting groove 1, the clamping piece 104 can apply pressure to the protection hoses 2, the pressing piece 105 generates a tendency to flatten the protection hoses 2, and then the protection hoses 2 are mutually pressed, so that the optical cable subunits 5 in each protection hose 2 are relatively stable.
As a preferred embodiment of the present application, the pressing piece 105 in the present application is an elastic pressing piece 105, and both ends of the pressing piece 105 are fixed to the inner wall of the installation groove 1. When the elastic hose is crimped by the pressing piece 105, in order to ensure stable crimping of the pressing piece 105, both ends of the pressing piece 105 are fixed on the inner wall of the installation groove 1, and the pressing piece 105 is made of an elastic material, so that after the pressing piece 104 is pressed by the pressing piece 105, the pressing piece 105 bends and presses the elastic hose, and after the elastic hose and the optical cable subunit 5 are drawn out, the pressing piece 105 can return to the original state for the next use.
As an alternative embodiment of the present application, the pressing sheet 105 is a rigid pressing sheet 105, both ends of which are slidably disposed on the inner wall of the mounting groove 1, and a telescopic spring is disposed between the first wall surface 101 and the pressing sheet 105. The preforming 105 that slides and set up can support protection hose 2 better to make the even atress of all protection hoses 2 in the mounting groove 1, ensure the stability of the optical cable subunit 5 in it, but need correspond between this preforming 105 and first wall 101 and set up telescopic spring, in order that elastic hose and optical cable subunit 5 take out the back of back preforming 105, and telescopic spring can give the joint piece 104 an abutment force equally, ensure that joint piece 104 stable joint is in mounting groove 1, avoid joint piece 104 not hard up in joint 103.
As a preferred embodiment of the present application, the protective sheath 3 of the present application is wound with an insulating tape. Since the protective cover 3 serves to isolate the optical cable sub-unit 5 from the outside, it is required to have an insulating capability itself, and it is required to ensure that the protective cover 3 connects the cable 4 to both ends of the installation groove 1 without generating a gap. For this purpose, the protective sheath 3 is usually manufactured on site, and after the protective hose 2 is threaded on the optical cable subunit 5 and sequentially threaded in the installation groove 1, the protective sheath 3 is formed between the cable 4 and the installation groove 1 by the insulating tape, so as to effectively protect the optical cable subunit 5 therein.
Preferably, since the insulating tape itself has flexibility, in order to avoid the cable subunits 5 in the adjacent installation groove 1 from being damaged by mutual extrusion, a protective side plate is disposed between the cable 4 and the installation groove 1, one end of the protective side plate is lapped on the cable 4, the other end thereof is lapped on the outer wall of the installation groove 1, the protective side plate has a certain convex radian, so that the protective side plate and the cable subunits 5 cannot be contacted, and then the insulating tape is wound around the periphery of the protective side plate to form the protective sleeve 3. Further preferably, the protection side plates are of a single-side structure, and the protection side plates are arranged on each installation groove 1, so that after the installation grooves 1 are stacked and formed, the upper side and the lower side of the optical cable subunits 5 in each installation groove 1 are protected by the protection side plates, and the optical cable subunits 4 cannot be mutually extruded. Optionally, the protective side plates are arranged along the integral structure formed by splicing the mounting grooves 1, and a cylindrical hard protective sleeve structure is formed between the cable 4 and the integral structure. Meanwhile, the protection side plate and the mounting groove 1 can be directly integrally formed and arranged, and can also be separately arranged with the mounting groove 1.
Furthermore, the application also comprises an installation method of the protective device of the expandable large-core optical cable subunit 5, which is implemented by means of the protective device, and specifically comprises the following steps:
s1: the outer sheath of the end part of the cable 4 to be connected is cut, and the cable is orderly arranged according to the internal standard sequence of the optical cable subunit 5;
the outer sheath of the cable 4 is in a variable cut-away form, preferably in a form of being unfolded from the middle to two sides, so that the outer sheath unfolded from the two sides is convenient to wind with the insulating tape; meanwhile, the optical cable subunit 5 is provided with a numerical label or a color label, and the optical cable subunit is only required to be sequentially arranged in a penetrating manner when correspondingly arranged in the mounting groove 1.
S2: selecting a corresponding accommodating number of mounting grooves 1, sequentially selecting optical cable subunits 5 according to the standard sequence of the optical cable subunits 5, penetrating the optical cable subunits 5 into the mounting grooves 1, and sleeving the protection hoses 2 on the optical cable subunits 5 one by one from one end of the mounting grooves 1, which is far away from the opening of the cable 4;
