Abstract
The invention discloses a kind of shielded cables with polytetrafluoroethylene ethylene layer, belong to shielding line field.It includes core wire, shielded layer and insulating buffer layer, the shielded layer is wrapped in outside core wire, the insulating buffer layer is filled between core wire and shielded layer, one lateral edge of core wire is axially provided with strip groove, the strip groove bottom is arc and the side wall with core wire away from strip groove side coincide, the strip groove bottom is provided with several limiting grooves being horizontally set with, and it is stupefied that the core wire is provided with several limit convexes corresponding with several limiting grooves on the side wall of strip groove side.The technical program is when both threads cable connects, the connector of one cable separates core wire and digs shielded layer, it is inserted into the strip groove of another cable connector, the shielded layer dug is wrapped up to the shielded layer of another cable again, can prevent the junction core wire of both threads cable from exposing and causing the problem of connecting with shielded layer.
Description
Technical field
The invention belongs to shielding line fields, are a kind of shielded cables with polytetrafluoroethylene ethylene layer specifically.
Background technique
Shielding line is the transmission line that core wire is wrapped up using metal net shaped braiding layer, braiding layer usually by red metal or
Tin-coated copper is made, and when connecting two shielding lines, usually the shielded layer of two shielding lines is peeled off, it will be in two shielding lines
Core wire is electrically connected, and is later again grounded the shielded layer of two shielding lines respectively.
Inventor in the implementation of the present invention, discovery aforesaid way need when at least having following defects that connection by
The core of two lines removes dew, and extending part can not effectively insulate upon connection with shielded layer, furthermore be unfavorable for two lines
Shielded layer be connected, junction formed shielding blind area the problem of.
Summary of the invention
Object of the present invention is to be intended to provide a kind of solution insufficient shielded cable with polytetrafluoroethylene ethylene layer in the prior art.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
A kind of shielded cable with polytetrafluoroethylene ethylene layer, including core wire, shielded layer and insulating buffer layer, the shielded layer are wrapped in
Outside core wire, the insulating buffer layer is filled between core wire and shielded layer, and one lateral edge of core wire is axially provided with strip groove, institute
It states side wall of the strip groove bottom for arc and with core wire away from strip groove side to coincide, if the strip groove bottom is provided with
The dry limiting groove being horizontally set with, the core wire are provided with several limits corresponding with several limiting grooves on the side wall of strip groove side
Position is convex stupefied.
It further limits, obturator is equipped in the strip groove.
It further limits, several partition grooves is provided on the obturator.
It further limits, the insulating buffer layer is made of polytetrafluoroethylene (PTFE).
It further limits, further includes heat-shrink tube, the heat-shrink tube is wrapped in outside shielded layer.
It further limits, the heat-shrink tube is single wall heat-shrink tube.
It further limits, the core wire quantity is at least one.
Compared with prior art, when the connection of both threads cable, the connector of a cable separates core wire and will shielding the present invention
Layer is dug, and is inserted into the strip groove of another cable connector, then the shielded layer dug is wrapped up to the shielded layer of another cable
On, it can prevent the junction core wire of both threads cable from exposing and causing the problem of connecting with shielded layer.
Detailed description of the invention
The present invention can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram of the shielded cable of the invention with polytetrafluoroethylene ethylene layer；
Fig. 2 is the structural schematic diagram of strip groove of the present invention；
Main element symbol description is as follows:
Core wire 1, shielded layer 2, insulating buffer layer 3, limiting groove 31, limit convex be stupefied 32, obturator 4, partition grooves 41, heat-shrink tube 5.
Specific embodiment
In order to make those skilled in the art that the present invention may be better understood, with reference to the accompanying drawings and examples to this hair
Bright technical solution further illustrates.
As shown in Figure 1 and Figure 2, a kind of shielded cable with polytetrafluoroethylene ethylene layer, including core wire 1, shielded layer 2 and insulation are slow
Layer 3 is rushed, the shielded layer 2 is wrapped in outside core wire 1, and the insulating buffer layer 3 is filled between core wire 1 and shielded layer 2, the core
1 one lateral edge of line is axially provided with strip groove, and the strip groove bottom is arc and deviates from the side of strip groove side with core wire 1
Wall coincide, and the strip groove bottom is provided with several limiting grooves 31 being horizontally set with, and the core wire 1 deviates from the side of strip groove side
Several limit convexes stupefied 32 corresponding with several limiting grooves 31 are provided on wall.
In the present embodiment, when the connection of both threads cable, the connector of a cable separates core wire 1 and digs shielded layer 2,
It is inserted into the strip groove of another cable connector, then the shielded layer 2 dug is wrapped up to the shielded layer 2 of another cable, energy
Enough prevent the junction core wire 1 of both threads cable from exposing and causing the problem of connecting with shielded layer 2；Meanwhile limiting groove 31 and limit
Position convex stupefied 32 is mutually clamped fixation, and the extruding of coordinated insulation buffer layer 3 is fixed, and junction is made to have certain structural strength.Institute
It states and is equipped with obturator 4 in strip groove.Several partition grooves 41 are provided on the obturator 4, obturator 4 is divided shape by partition grooves 41
At several sections, the obturator 4 that extraction does not have to quantity can according to need.The insulating buffer layer 3 is made of polytetrafluoroethylene (PTFE).Also
Including heat-shrink tube 5, the heat-shrink tube 5 is wrapped in outside shielded layer 2, and heat-shrink tube 5 can turn down in advance in connection, upon connection
It is being covered in outside junction, then is being fixed by heating, improving the airtightness of junction.The heat-shrink tube 5 is single wall heat-shrink tube 5.
1 quantity of core wire is at least one.
The shielded cable provided by the invention with polytetrafluoroethylene ethylene layer is described in detail above.Specific embodiment
Illustrate to be merely used to help understand method and its core concept of the invention.It should be pointed out that for the common skill of the art
, without departing from the principle of the present invention, can be with several improvements and modifications are made to the present invention for art personnel, these change
It is also fallen within the protection scope of the claims of the present invention into modification.
