A kind of butterfly optical cable connects mould
Technical field
the utility model relates to fiber optic cable manufacturing equipment technical field, is specially a kind of butterfly optical cable and connects mould.
Background technology
in butterfly optical cable production run, need to connect optical fiber and the auxiliary reinforcements such as steel wire, so need to use, connect mould, in prior art, as the Chinese utility model patent that notification number is 201886188U has been announced a kind of durable type butterfly optical cable mould, the mode that adopts core rod and core rod seat integral body to match, so all can be larger to core rod seat and core rod damage in use, and positioning requirements is higher, assemble up cumbersomely, thereby exist in addition, on optical fiber itself, cause damage to affect the risk of optical cable quality.
Utility model content
the purpose of this utility model is to provide a kind of longer service life, be convenient to assembling and the butterfly optical cable that connects connects mould.
above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of butterfly optical cable connects mould, comprise die sleeve and guiding mould, die sleeve has the cavity of connecting, connect cavity and comprise that the section of drawing of head end and tail end insert fixing canned paragraph for guiding mould, the section of drawing comprises the optical fiber section of drawing and is positioned at the reinforcement section of drawing of the optical fiber section of drawing both sides, guiding mould is provided with and the optical fiber section of drawing and the reinforcement section of drawing fiber guides passage and reinforcement guiding channel one to one, along the optical fiber section of drawing and fiber guides passage, be provided with an optical fiber pillar that runs through die sleeve and guiding mould.
such scheme; make Mould Machining convenient formation; assembling is simple, by the design of a whole piece optical fiber pillar, makes connecting of optical fiber simpler; phenomenon can not result in blockage; also optical fiber itself has been played to good protective effect, and reinforcement mainly adopts steel wire or FRP material, compares optical fiber material harder simultaneously; guidance quality is good, adopts pillar mode and do not adopt pillar mode to connect all feasible.
as to of the present utility model preferred, guide mould to be formed by two symmetrical mould lobes.
as preferably guiding mould is the cylindricality mould of the whole ovalize of xsect to of the present utility model, the import and export of fiber guides passage are the place, center of bottom surface on guiding mould respectively.This is preferably convenient to mould contraposition and assembling.
as to of the present utility model preferred, connect cavity and between the section of drawing and canned paragraph, also there is one section of transition section.Can improve serious forgiveness, there is the possibility that occurs deviation in guiding mould orientation assemble, makes reinforcement and still connect in certain space of adjusting.
the beneficial effects of the utility model are: this butterfly optical cable connects mould can reduce producting process difficulty, and simply, less to the damage of mould itself and optical fiber, die life is extended for assembling, location, and production cost reduces simultaneously.

Embodiment
following specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this instructions, but as long as within the scope of claim of the present utility model, are all subject to the protection of Patent Law.
embodiment 1, as Fig. 1, 2, 3, shown in 4, a kind of butterfly optical cable connects mould, comprise die sleeve 1 and guiding mould 2, die sleeve 1 has the cavity of connecting, connect cavity and comprise that the section of drawing of head end and tail end insert fixing canned paragraph 102 for guiding mould 2, the section of drawing comprises the optical fiber section of drawing 1011 and is positioned at the reinforcement section of drawing 1012 of the optical fiber section of drawing 1011 both sides, guiding mould 2 is provided with and the optical fiber section of drawing 1011 and the reinforcement section of drawing 1012 fiber guides passage 2011 and reinforcement guiding channel 2012 one to one, along the optical fiber section of drawing 1011 and fiber guides passage 2011, be provided with an optical fiber pillar 3 that runs through die sleeve 1 and guiding mould 2.Guiding mould 2 is the cylindricality mould of the whole ovalize of xsect, and the import and export of fiber guides passage 2011 are the place, center of bottom surface on guiding mould 2 respectively.Guiding mould 2 is comprised of two symmetrical mould lobes.
embodiment 2, and as shown in Figure 5, the difference of itself and embodiment 1 is: connect cavity and between the section of drawing and canned paragraph 102, also have one section of transition section 103.
