Description

The flexible shielding bus

Technical field

The utility model relates to a kind of shielding bus, is used to realize being electrically connected between the electric switch cabinet.

Background technology

Traditional bus is a hard solid shielding bus, and is mostly straight shape, bending, in installation process operation more numerous and diverse, also more restricted aspect size, and area occupied is big, can not universal flexible connection.Can not solve the electric field problem, and can not accomplish that no office puts.In the actual installation use, because the crooked size of bus is limited, reasons such as underaction are difficult for installing, and waste time and energy the waste resource.

The utility model content

The problem that the utility model mainly solves is, to the problem that traditional connected mode exists, traditional structure improved, and a kind of flexible shielding bus that can convenient and swift connection is provided.

Be to realize above-mentioned purpose, the utility model provides a kind of flexible shielding bus, and it can be the flexible shielding bus that adopts the integral type design, it comprise can multi-faceted flexible bending fexible conductor; Circumferentially be coated on the outer conductor overcoat of conductor; Be fixed on the terminal on the said conductor; And, be sealedly attached to the part outside that said conductor cooperates with terminal, be used to solve the electric field problem so that bus becomes the stress evacuating body that bus is put in no office.

Preferably, said fexible conductor is a stranded copper wire, and said stranded copper wire preferably adopts the mode of spiral winding to arrange.

Further, said conductor overcoat is three layers of injection rubber conductor overcoat, comprises conduction internal layer, insulating barrier and skin that order is provided with.

Further, segment conductor is outside the conductor overcoat axially stretches out conductor overcoat end face, and said terminal is fixed on this conductor part that stretches out the conductor overcoat.

Preferably, said terminal has concave part, and conductor stretches into and is fixed in this concave part, and this concave part is against on the conductor overcoat end face.

Further, said conductor overcoat ground connection.

It is limited that the utility model has solved common bus installation dimension, and reasons such as multi-faceted cooperation underaction are with adopting hard solid bus originally; Change flexible bus into; Bus is installed can be connected in universal stretching, extension, can not wait with any direction, different angles, height, different other of length dispose multi-faceted connection, and making takes up room minimizes, installs more efficient and convenient, cabinet miniaturization, standardization; Cooperation is more simplified, and can be cooperated with multiple cabinet.

The utility model adopts integral type design, compact conformation, good airproof performance.

The utility model changes original common solid bus the flexible bus that no office puts into, and is provided with the stress evacuating body, has solved the electric field problem.

Embodiment

In order to make the utility model flexible shielding bus, be easy to understand and understand, below in conjunction with concrete diagram, set forth the utility model in detail.

Like Fig. 1,2, shown in 3, said flexible shielding bus 100 comprises conductor, conductor overcoat 20, terminal 30 and stress evacuating body 40.

Said conductor 10 can be various fexible conductors, for example is made up of stranded copper wire, said stranded copper wire close arrangement; It for example can be the arrangement of spiral winding; Because stranded copper wire is compared solid conductor, for example the copper rod flexibility is good, therefore can be under the effect of suitable power; For example under the bending effect of hand, bend.

Conductor overcoat 20 circumferentially is coated on conductor 10 outsides, and conductor 10 can be protruding from the axial end of conductor overcoat.Said conductor overcoat is three layers of injection rubber bodies, comprises from being close to the outwards conduction internal layer 201, the insulating barrier 202 that are provided with of order of conductor, and skin 203.

The part of stretching out conductor overcoat 20 in the face of the conductor 10 of a side is down described, and opposite side is also identical, repeats no more.

The part of stretching out from the conductor overcoat of conductor 10 is fixing with terminal 30.Terminal 30 can as shown in the figurely comprise that one is used for the connecting portion 31 that is electrically connected with outside connector 200, and the concave part that is used for bonding conductor 32 that extends to the inside from this connecting portion.In a kind of optional execution mode, conductor can stretch in the concave part 32, and can be through realizing fixing from circumferential extruding concave part and concave part, and concave part can be against on the end face of conductor overcoat.

Stress evacuating body 40 is sealedly attached to the connecting portion outside of terminal 30 and conductor 10.Its form can be the tubular stress evacuating body shown in Fig. 1 to 3.But preferably this stress evacuating body is sealedly attached to the concave part outside of terminal 30.The setting of stress evacuating body can solve the electric field problem, makes this flexibility bus put bus for no office.

Through adopting fexible conductor, it is limited that the utility model has solved common bus installation dimension, reasons such as multi-faceted cooperation underaction; With adopting hard solid bus originally, change flexible bus into, bus is installed can be connected in universal stretching, extension; Can not wait with any direction, different angles, height, different other of length dispose multi-faceted connection; Making takes up room minimizes, installs more efficient and convenient, cabinet miniaturization, standardization, cooperation is more simplified, and can be cooperated with multiple cabinet.

In addition, through adopting the stress evacuating body, the utility model changes original common solid bus the flexible bus that no office puts into, and is provided with the stress evacuating body, has solved the electric field problem.

Further, through the design of integral type, the flexible bus in the utility model has been realized good sealing structure.

In addition, bus can be the flexible bus of tangible type, and promptly outer surface can be provided with earthing device 50 and is used for ground connection.

As shown in Figure 4, said flexible shielding bus matches with connector 200, and said connector can be multiple connector, and for example body is a rubber bodies, and said rubber bodies is the connector of three layers of injection silicon rubber.

Being merely the embodiment of the utility model in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
