Abstract
The utility model discloses a high-temperature conductor, which comprises a conductor core, an insulating layer and a weaving protection layer that are wrapped sequentially from inside to outside, wherein the insulating layer consists of a first insulating layer and a second insulating layer that is wrapped outside the first insulating layer; the conductor core adopts a multi-strand nickel-clad copper stranded conductor core; both the first insulating layer and the second insulating layer adopt polyimide laminated films; and the weaving protection layer adopts a weaving glass fiber protection layer. In the utility model, with the adoption of the structure and the materials, the high-temperature conductor can meet the requirements of high reliability of the connection of an electric signal, good high temperature resistance, small volume and light weight and can also meet the requirement of the specific environment with high temperature.
Description
Technical field
The utility model relates to a kind of high temperature wire, particularly relates to a kind of high temperature wire of the conductor wire core of parcel, insulating barrier and woven protective layer formation successively that has from inside to outside.
Background technology
At present day applied lead all adopts the product of high temperature resistant class on 250 ℃～400 ℃ operational environment places.Hot environment is had relatively high expectations to this series products, generally all requires to have the signal of telecommunication and passes requirements such as the reliability, heat-resisting quantity, the volume that connect are little, in light weight.
Usually, because general its resistance to elevated temperatures of lead of fluoroplastic insulation that adopts does not reach requirement (having only 150 ℃～250 ℃), therefore under specific high ambient conditions, exist that wire insulation meets that hot non-deformability is poor, problems such as cisco unity malfunction, volume are big, Heavy Weight.
Summary of the invention
Technical problem to be solved in the utility model is, the reliability height that provides a kind of signal of telecommunication to pass to connect, heat-resisting quantity is good, volume is little, lightweight high temperature wire, to satisfy the high temperature wire at hot environment field needs.
The technical scheme that the utility model adopted is: a kind of high temperature wire, include the conductor wire core, insulating barrier and the woven protective layer that wrap up successively from inside to outside, described insulating barrier is to be made of with second insulating barrier that is wrapped in first insulating barrier outside is two-layer first insulating barrier.
Described conductor wire core adopts multiply nickel-clad copper bundle twisted wire core.
Described first insulating barrier and second insulating barrier all adopt polyimide composite film.
Described woven protective layer is to adopt the braided glass filament sheath.
High temperature wire of the present utility model owing to adopt said structure and material, when guaranteeing to reach that the signal of telecommunication passes the reliability height that connects, heat-resisting quantity is good, volume is little, lightweight high temperature wire requires, can also satisfy the needs of high temperature specific environment.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Wherein:

Insulating barrier 4 in 3: the second: woven protective layer
5: insulating barrier
Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify high temperature wire of the present utility model and how to realize.
As shown in Figure 1, high temperature wire of the present utility model includes from inside to outside conductor wire core 1, insulating barrier 5 and the woven protective layer 4 of parcel successively.Wherein:
Described conductor wire core 1 adopts multiply nickel-clad copper bundle twisted wire core.
Described insulating barrier 5 is by first insulating barrier 2 and is wrapped in that second insulating barrier 3 in first insulating barrier, 2 outsides is two-layer to be constituted that described first insulating barrier 2 and second insulating barrier 3 all adopt polyimide composite film.That is to say that wrapped two-layer first insulating barrier 2 and second insulating barrier 3 that is made of the same material polyimide composite film forms insulating barrier 5 jointly on conductor wire core 1.
Described outermost woven protective layer 4 is to adopt the braided glass filament sheath, forms the high temperature protection layer.
The main performance of high temperature wire of the present utility model is as shown in the table.
