Abstract
The utility model discloses cable splice closure, comprise upper shell, lower house, fusion joining disk, optical cable fixed mount, strengthening core fixed mount and sealing strip, fusion joining disk, optical cable fixed mount and strengthening core fixed mount are located on lower house, fluted on described upper shell and lower house, groove on upper and lower casing is corresponding, described sealing strip is arranged in groove, fits, it is characterized in that: have taper rib in described groove with the surface of groove; The surface at described groove two ends is provided with inner groovy.The utility model structure is simple, but can solve the defect existing for prior art preferably, can increase the life-span of silica gel sealing bar, increases sealing, is worthy to be popularized.
Description
Technical field
The utility model relates to the constructing technology field of optical cable connecting device, refers to a kind of cable splice closure especially.
Background technology
Cable splice closure is the popular of optical cable connecting box, also known as cable connection bag, fiber cable joint bag and gun barrel.Belonging to mechanical pressure sealing adaptor system, is provide optics, sealing and physical strength the successional protective device that continues between adjacent optical cable.Mainly be connected with branch the straight-through of system of laying such as built on stilts, pipeline, direct-burried being applicable to various structure optical cable.The Chinese patent of " hermetically-sealed construction of cable splice closure " (patent No. is: ZL201220397712.8) by name, disclose a kind of structure of cable splice closure, but still there is sealing loosely in this structure, and the easy crimp of O-ring seal, the defect that the life-span is low.How correcting above-mentioned defect, is the problem that technological improvement needs to solve.
Summary of the invention
The purpose of this utility model is to provide a kind of structure simple, convenient and strength-saving and can improve and be assembled into power, the joints of optical fibre assembling tool of minimizing parts breakage.
For realizing the purpose of this utility model, intend by the following technical solutions:
Cable splice closure, comprise upper shell, lower house, fusion joining disk, optical cable fixed mount, strengthening core fixed mount and sealing strip, fusion joining disk, optical cable fixed mount and strengthening core fixed mount are located on lower house, fluted on described upper shell and lower house, groove on upper and lower casing is corresponding, described sealing strip is arranged in groove, fits, it is characterized in that: have taper rib in described groove with the surface of groove; The surface at described groove two ends is provided with inner groovy.When upper shell and lower house link together, meeting crush seal bar, when sealing strip is extruded, the taper rib in groove snaps in sealing strip, increases sealing effectiveness.At the two ends of groove, can not expose outside housing by extruded sealing strip, and inner groovy can be entered into, thus ensure energy seamless link between upper and lower casing, the sealing strip of highly extruding also can be allowed to be released pressure, can not damage because of overvoltage.
Further, the opening of described inner groovy is parallel with groove surfaces.Sealing strip laminating groove surfaces, when squeezed, unnecessary press section potential energy enters into inner groovy completely, thus can not push up firm upper and lower casing.
Further, described sealing strip is silica gel sealing bar.
In use, when the closed connection of upper and lower casing, silica gel sealing bar is squeezed the utility model, and silica gel sealing ring has the position of overflowing groove, and taper rib snaps in silica gel sealing bar, and at groove two ends, unnecessary silica gel sealing bar can enter in inner groovy.Thus, the extruding of upper and lower casing to silica gel sealing bar can be reduced, also can reduce the gap between upper and lower casing, increase sealing property.
Accompanying drawing explanation
Fig. 1 is structural representation after the assembling of the utility model embodiment.
Fig. 2 is the structural representation after the utility model embodiment upper shell partly cuts open along A-A '.
Fig. 3 is the enlarged drawing at the utility model Embodiment B position.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
Composition graphs 1, Fig. 2 and Fig. 3, the utility model relates to a kind of cable splice closure, comprise upper shell 1, lower house 2, fusion joining disk 3, optical cable fixed mount 4, strengthening core fixed mount 5 and silica gel sealing bar 6, on described upper shell 1 and lower house 2 fluted 7, and corresponding; Described silica gel sealing bar 6 is arranged in groove 7, fit with the surface of groove 7, fusion joining disk 3, optical cable fixed mount 4 and strengthening core fixed mount 5 are located on lower house 2, have taper rib 8 in described groove 7, the surface at two ends is provided with inner groovy 9, and the opening of inner groovy 9 is parallel with groove 7 surface.When upper shell 1 links together with lower house 2, silica gel sealing bar 6 can be extruded, and taper rib 8 can snap in silica gel sealing strip of paper used for sealing 6; When silica gel sealing bar 6 is extruded, the part that both sides are unnecessary, also can not expose outside housing, inner groovy 9 can be entered into, thus energy seamless link between guarantee upper and lower casing, the silica gel sealing bar 6 of highly extruding also can be allowed to be released pressure, can not to damage because of overvoltage.
The utility model structure is simple, but can solve the defect existing for prior art preferably, can increase the life-span of silica gel sealing bar, increases sealing, is worthy to be popularized.
