Abstract
The utility model discloses a structure for fixing aramid fiber of a watertight photoelectric composite cable connector. The structure comprises a connector body; the connector body has a cylindrical center hole; the right end face of the connector body is provided with a truncated conical center hole with a externally-large and internally-small structure, the truncated conical center hole being arranged at the opening of the cylindrical center hole; a fitted truncated hollow cone is arranged inside the truncated conical center hole so as to form a double-conical-face nested self-locking structure. According to the structure for fixing the aramid fiber, when the structure is used, one end of the watertight photoelectric composite cable is arranged inside the connector body; one end of the aramid fiber of the watertight photoelectric composite cable is evenly placed in accordance with a stranding direction on a conical face form by the truncated conical center hole at the connector body and then is plugged into the truncated hollow cone, and is further bonded and compressed; and the aramid fiber can be firmly fixed though the clamping effect of the double-conical-face nested self-locking structure formed by the truncated conical center hole and the truncated hollow cone, and therefore, the anti-tension reinforcing effect of the aramid fiber for the watertight photoelectric composite cable can be guaranteed.
Description
Technical field
The utility model relates to a kind of watertight optoelectronic composite cable joint, relates in particular to a kind of aramid fiber fixed structure of watertight optoelectronic composite cable joint.
Background technology
Owing to preventing that the watertight optoelectronic composite cable from receiving the external force effect in the process of the test under water and damaging, require the watertight optoelectronic composite cable to have bigger stretching resistance generally speaking.Common flexible watertight optoelectronic composite cable adopts the multiply aramid fiber to strengthen, because aramid fiber, makes the folding and unfolding use repeatedly of watertight optoelectronic composite cable than soft many of steel wire reinforced effects, tests under water and lays fast and reclaim thereby be convenient to the user.For the whole mechanical property transmission of watertight optoelectronic composite cable, on its joint, needing increases the aramid fiber fixed part, and composite rope, joint and headend equipment are formed integral body, improves joint and composite rope connection reliability.Existing aramid fiber fixed part is generally monomer structure, directly the multiply aramid fiber is bonded on the aramid fiber fixed part through epoxy glue.Yet fixing of this aramid fiber fixed part is not firm, thereby is prone to make aramid fiber to lose the effect of the resistance to tension that strengthens the watertight optoelectronic composite cable.
The utility model content
The purpose of the utility model is to provide a kind of aramid fiber fixed structure of watertight optoelectronic composite cable joint, to guarantee the tension reinforced effects of aramid fiber for the watertight optoelectronic composite cable.
For achieving the above object; The utility model provides a kind of aramid fiber fixed structure of watertight optoelectronic composite cable joint; Comprise adapter body, said adapter body has cylindrical center bore, the frustoconical centre bore that imperial palace is little outside the tapping that is positioned at said cylindrical center bore has on the right side of said adapter body; The butt hollow cone of cooperation is installed in the said frustoconical centre bore, thereby constitutes the nested self-locking structure of bipyramid face.
The aramid fiber fixed structure of the watertight optoelectronic composite cable joint of the utility model, the angle between the bus of said butt hollow cone and its axis are 6 ° to 8.5 °.
The aramid fiber fixed structure of the watertight optoelectronic composite cable joint of the utility model, the surface roughness of the conical surface that said frustoconical centre bore forms on said adapter body and the side of said butt hollow cone all is about 6.4.
The aramid fiber fixed structure of the watertight optoelectronic composite cable joint of the utility model has sulfuration and reinforces groove on the outer surface of said adapter body.
The aramid fiber fixed structure of the watertight optoelectronic composite cable joint of the utility model comprises adapter body; Adapter body has cylindrical center bore; The frustoconical centre bore that imperial palace is little outside the tapping that is positioned at cylindrical center bore has on the right side of adapter body is equipped with the butt hollow cone of cooperation in the frustoconical centre bore, thereby constitutes the nested self-locking structure of bipyramid face; During use; Watertight optoelectronic composite cable one end is packed in the adapter body, an end of the aramid fiber of protection watertight optoelectronic composite cable evenly is placed on the frustoconical centre bore on the conical surface that forms on the adapter body according to direction of lay, fill in the butt hollow cone then; Bonding compressing; Because the clamping action of the frustoconical centre bore and the nested self-locking structure of bipyramid face of butt hollow cone formation, what aramid fiber can be firm is fixing, thereby has guaranteed the tension reinforced effects of aramid fiber for the watertight optoelectronic composite cable.
Description of drawings
Fig. 1 is the cutaway view of aramid fiber fixed structure of the watertight optoelectronic composite cable joint of the utility model.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model:
With reference to shown in Figure 1; Part as watertight optoelectronic composite cable joint; The aramid fiber fixed structure of the watertight optoelectronic composite cable joint of present embodiment comprises adapter body 1, has sulfuration on the outer surface of adapter body 1 and reinforces groove 5, so that the sulfuration of follow-up whole watertight optoelectronic composite cable joint sealing; Adapter body 1 has cylindrical center bore 2; The frustoconical centre bore 3 that imperial palace is little outside the tapping that is positioned at cylindrical center bore 2 has on the right side of adapter body 1 is equipped with the butt hollow cone 4 of cooperation in the frustoconical centre bore 3, frustoconical centre bore 3 and butt hollow cone 4 constitute the nested self-locking structure of bipyramid faces.For realizing self-locking, generally speaking, the coefficient of friction between the related material is not less than 0.15; In the present embodiment, for guaranteeing enough coefficient of frictions, the angle between the bus of butt hollow cone 4 and its axis is an arbitrary value between 6 ° to 8.5 °; And; The conical surface that frustoconical centre bore 3 forms on adapter body 1 and the side of butt hollow cone 2 will have certain adhesive force, can not be too smooth, and its surface roughness is about 6.4 and gets final product.During use; Watertight optoelectronic composite cable 6 one ends are packed in the adapter body 1, an end of the aramid fiber of protection watertight optoelectronic composite cable 6 evenly is placed on frustoconical centre bore 3 on the conical surface that forms on the adapter body 1, after all aramid fibers load quantitative load according to direction of lay; Coat epoxy glue; Fill in butt hollow cone 4 then, compress, solidify.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection range that claims of the utility model confirm.
