Description
One, technical field:
The utility model is specifically related to a kind of Bundled cable component low-pressure injection molding sheath, and Bundled cable component is exclusively used in communication base station association area.
Two, background technology:
Along with the fast development of mobile communication cause, demand to Bundled cable component increases day by day, but due to the harsh requirement of this product environment for use, we must be protected region of interest such as the joint-cuttings of connector and cable junction and cable sheath, what but traditional protected mode was substantially all used is that heat-shrinkable T bush or film Heat-Shrinkable Tubings (inner wall belt glue heat-shrinkable T bush) carry out pyrocondensation, can reach corresponding protection effect; Mechanical Reliability and sealing property require when more harsh, can also adopt and first pour into corresponding 9001A/B glue, and then the mode that pours into 703 fluid sealants reinforces, and ensure sealing property.But such protected mode is for the informationized society of current high speed development, and production efficiency is to have lagged behind very much really, and also very harsh for the requirement of production site, and production scene is quite in disorder, substantially cannot realize the pipelining of enhancing productivity.If but we are changed into the protected mode at Bundled cable component sheath place the form of injection moulding (mold pressing) sheath by the film draw; existing production model will have greatly change; and a kind of fashion trend of injection moulding sheath Ye Shi modern social development; each large electronic product, comprises that related components used on Aeronautics and Astronautics, steamer, train, automobile has all adopted the protection of being correlated with of the form of injection moulding.Injection moulding will substitute heat-shrinkable T bush and film Heat-Shrinkable Tubings from now on very soon as a kind of pattern of protection connector and cable region of interest, and this is also a kind of inexorable trend.
The cable insulation medium using on L32 Bundled cable component is foamed polyethylene; and attaching is also divided into two kinds of the boundling attaching of sub-thread cable and the attachings of whole strand cable boundling, this just means that common engineering injection molding machine and mould cannot complete the operation of protection region of interest.Due to the attaching pattern of assembly and the restriction of the construction of cable, force us to have to use existing protected mode.First, the cover related film draw, then loads onto connector and pours into 9001A/B glue at its tail dependence position, after 9001A/B glue 12H spontaneous curing, put it into again and in baking oven, dry 1H, dried and poured into 703 fluid sealants again, after 703 fluid sealant 12H spontaneous curings, one section of film draw contracts, a part that reserves afterbody does not contract, at afterbody deconcentrator, place pours into 9001A/B glue, puts into baking oven and dries 1H, finally again by complete the pyrocondensation of film draw entirety after 12H spontaneous curing.In actual mechanical process, be difficult to control to fill with amount and the ratio of various glue, and workman's operation technique required tighter, follow-uply also will toast processing.In the whole course of processing, operation is loaded down with trivial details, operability is poor, and the consistency of product quality is difficult to management and control.
Along with the continuous lifting of the fast-developing demand of informationization, tackle mutually the continuous growth of Bundled cable component annual consumption, annual consumption up to a million, all lean on manual encapsulating and artificially overlap, the contracting film draw completes, not only increase operational sequence, strengthen workman's operation easier, also badly influence production capacity and the delivery cycle of my company's Bundled cable component, thereby also the annual earnings of my department will be had a strong impact on, and the more difficult to govern control of quality conformance, every batch all needs to extract a certain proportion of product and does destructive testing, for example pull test, rolling test etc., virtually increase to a great extent our production cost.The civilian upper unit price of Bundled cable component is lower; cause our cost pressure larger; and very large production space and a large amount of equipment are taken; need a large amount of human and material resources; management cost is larger; these aspects comprehensively be it seems and all shown; this product junction is badly in need of another production model and is shaped protection; not only hommization more in production technology operation; and can save space, the cost such as human and material resources; the comprehensive production cost that reduces my department, the consistency of quality between the reliability of guarantee product and different batches.
Three, utility model content:
The utility model, in order to solve the weak point in above-mentioned background technology, provides a kind of Bundled cable component low-pressure injection molding sheath.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Bundled cable component low-pressure injection molding sheath, comprise cable, and it is characterized in that: also comprise injection moulding major part and injection moulding microcephaly, described injection moulding major part is connected by cable with injection moulding microcephaly,
Described injection moulding major part comprises injection moulding sheath one, described injection moulding sheath one is disposed with separated time collar and support card near one end of injection moulding microcephaly, between described separated time collar and support card, be folded with sealing ring, on described separated time collar, arrange porose, described cable is arranged in the hole of separated time collar, between sealing ring and support card, the described interior space of injection moulding sheath one place is filled with PUR;
Described injection moulding microcephaly comprises injection moulding sheath two, in described injection moulding sheath two, is filled with PUR.
Described sealing ring is stifled glue sealing ring.
