Description

Shielded tube

Technical field

This utility model is related to tubing technical field, specifically, is related to a kind of shielded tube.

Background technology

Track traffic, aviation, military project, electric power, lathe dispatch control system are provided with a lot of wire harness, and equipment is in operation and has height Frequency or significantly vibrations and electromagnetic interference, are easily caused wire harness and are rubbed with the equipment contacting, for a long time during vibrations Friction can damage wire harness and lead to device fails, in order to protect cable, typically fill one layer of heat-shrink tube or pvc in wire harness overcoat Pipe, so would not damage the cable of the inside during vibrations, although cable can be protected well, but equipment is in fortune Various signals are transmitted between these wire harness, these signals can interfere with each other in transmission, and interference signal also can affect to set during row Standby normal work, typically utilizes the ground connection of wave prevention sleeve wire harness to filter interference signal, this filtration often stays remaining on a small quantity Ripple, and the interference with external signal from system cannot be shielded, run to equipment and bring hidden danger.

Content of the invention

The purpose of this utility model is to provide a kind of shielded tube, has good capacity of resisting disturbance, and adjustable interior Footpath.

Disclosed in this utility model, shielded tube be the technical scheme is that

A kind of shielded tube, including external protection and internal shield, described external protection located at the outer surface of internal shield, One end of described internal shield is provided with tin-coated copper webmaster, and described tin-coated copper webmaster is wrapped on internal shield, described internal shield The inner surface of the other end be provided with hook face VELCRO, the outer surface of one end of described external protection is provided with hair side VELCRO, described Hook face VELCRO on internal shield is overlapped in the hair side VELCRO on external protection, and described internal shield is aluminium foil layer.

Preferably, one end of described internal shield folds and forms cavity volume, and described tin-coated copper webmaster is in cavity volume.

Preferably, described internal shield one end forms cavity volume by sewing machine sewer.

Preferably, described hook face VELCRO passes through sewing machine sewer in the inner surface of the internal shield other end.

Preferably, described external protection is made up of tpu material.

Preferably, described external protection is made up of the mixture of tpu, polycarbodiimide and epoxy resin.

Preferably, described hair side VELCRO passes through sewing machine sewer in the outer surface of external protection one end.

Preferably, described tin-coated copper webmaster is wrapped on internal shield by aluminium strip.

The beneficial effect of shielded tube disclosed in this utility model is: is overlapped in hair side magic by adjusting hook face VELCRO The position sticked, the internal diameter of adjustment shielded tube, described aluminium foil layer is used for shielding outer signals, it is to avoid it passes in shielded tube The cable of defeated signal interferes, and described tin-coated copper webmaster is used for being grounded, because tin-coated copper webmaster contacts well with aluminium foil layer, will Conductance on aluminium foil layer is to greatly.

Brief description

Fig. 1 is the structural representation of this utility model shielded tube.

Specific embodiment

With reference to specific embodiment and Figure of description, this utility model is further elaborated and illustrates:

Refer to Fig. 1, a kind of shielded tube, including external protection 2 and internal shield 1, described external protection 2 is located at interior screen Cover the outer surface of layer 1, described internal shield 1 is aluminium foil layer, described external protection 2 is made up of tpu material.

One end of described internal shield 1 folds, and forms cavity volume by sewing machine sewer, is provided with tin plating copper mesh in described cavity volume Pipe 3, the inner surface of the other end of described internal shield 1 is provided with hook face VELCRO 5, and described hook face VELCRO 5 passes through sewing machine linear slit It is formed on the inner surface of internal shield 1 other end, the outer surface of one end of described external protection 2 is provided with hair side VELCRO 4, described hair Face VELCRO 4 is taken by hook face VELCRO 5 on the outer surface of external protection 2 one end, described internal shield 1 for the sewing machine sewer The hair side VELCRO 4 being connected on external protection 2 forms shielded tube, is overlapped in hair side VELCRO 4 by adjusting hook face VELCRO 5 On position, adjustment shielded tube internal diameter.

Described aluminium foil layer is used for shielding outer signals, it is to avoid it interferes to the cable of transmission signal in shielded tube, Described tin-coated copper webmaster 3 is used for being grounded, because tin-coated copper webmaster 3 contacts well with aluminium foil layer, by the conductance on aluminium foil layer to big Ground, it is to avoid get an electric shock, tpu material wear-resistant, the external protection 2 that it is made is wear-resisting, can improve the service life of shielded tube.

External protection also can be made up of the mixture of tpu, polycarbodiimide and epoxy resin, improve its mechanical property and Hydrolytic resistance.

In above-described embodiment, tin-coated copper webmaster is wrapped up by aluminium foil layer, also can use fine aluminium that tin-coated copper webmaster is fixed on aluminium foil Layer, makes tin-coated copper webmaster contact well with aluminium foil layer.

Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general Lead to it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this The spirit and scope of utility model technical scheme.
