Description
Technical field
It the utility model is related to technical field of automobile accessories, and in particular to a kind of wire harness.
Background technology
The wire harness for automobile is usually to be fettered using tank chain as protective case now, is then entered again by fixture
Row fixation, the connection between fixture and tank chain is insecure, and easily skew winds the wire in tank chain, meeting when serious
Tank chain inside conductor is pulled, and due to wire harness in auto-body inner packaging, it is necessary to bending part welt arrange, usually because
For improper inner conductor and the guarantor for causing to extrude between the wire inside wire harness and wire, causing wire of angle of bending
Sheath is damaged, wherein, when the cross section of the inner conductor of wire is impaired becomes small, the resistance of wire will be increased, have impact on electricity
The transmission speed of signal.
Utility model content
In order to solve the above technical problems, we have proposed a kind of wire harness, its purpose：Jail is connected between fixture and protective case
Gu preventing that Er wire from pulling because by external force, reduction is in the extruding force that the wire of bending part is subject to.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of wire harness, including protective case, the lateral surface of protective case are laid with metal net layer and outer protection successively from the inside to the outside
Layer, external protection are provided with the annular groove that cross section is isosceles trapezoid, connection card tool are socketed with annular groove；
Hollow elastic supporting pipe is provided with protective case and at least six conductors, wire are in hollow elastic supporting pipe and protection
Between set inwall；
Wire includes conductor, and the lateral surface of conductor is electroplate with silver layer, and the lateral surface of silver layer is provided with insulating protective layer.
Preferably, the material of conductor is copper, and hollow elastic supporting pipe and the material for connecting fixture are rubber.
Pass through above-mentioned technical proposal, the lateral surface of protective case are laid with metal net layer and external protection successively from the inside to the outside,
External protection is adhered to by way of hot melt adhesive on the lateral surface of protective case, and protective case and outer protection are strengthened in metal net layer
The tensile strength of layer, it is therefore prevented that wire is pulled because by external force, and external protection is provided with the annular that cross section is isosceles trapezoid
Groove, connection card tool is socketed with annular groove so that be connected firmly between fixture and protective case, facilitate subsequent fixed, protected
Hollow elastic supporting pipe is provided with sheath, when the wire harness is in bending part, hollow elastic supporting pipe can deform upon automatically
The extruding force that wire is subject to is shared, reduces and is in the extruding force that the wire of bending part is subject to, wherein, metal net layer can isolate
Outside electromagnetic interference, it is therefore prevented that the electric signal in conductor is by electromagnetic interference.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only

31. the silver insulating protective layer of layer 33. of conductor 32..
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Specific embodiment of the present utility model is described in further detail with reference to schematic diagram.
As shown in Figure 1, Figure 2 and Figure 3, a kind of wire harness, including protective case 1, the lateral surface of protective case 1 apply successively from the inside to the outside
Provided with metal net layer 11 and external protection 12, external protection 12 is adhered to by way of hot melt adhesive on the lateral surface of protective case 1,
The tensile strength of protective case 1 and external protection 12 is strengthened in metal net layer 11, it is therefore prevented that wire 3 is pulled because by external force,
Wherein, metal net layer 11 can isolate outside electromagnetic interference, it is therefore prevented that the electric signal in conductor 31 is by electromagnetic interference.
External protection 12 is provided with the annular groove that cross section is isosceles trapezoid, and connection card tool is socketed with annular groove
13 so that be connected firmly, facilitate subsequent fixed between fixture and protective case.
Hollow elastic supporting pipe 2 is provided with protective case 1 and at least six conductors 3, wire 3 are in hollow elastic supporting pipe 2
Between the inwall of protective case 1, when the wire harness is in bending part, hollow elastic supporting pipe 2 can be deformed upon to share and led automatically
The extruding force that line 3 is subject to, reduce and be in the extruding force that the wire 3 of bending part is subject to.
Wire 3 includes conductor 31, and the lateral surface of conductor 31 is electroplate with silver layer 32, and the lateral surface of silver layer 32 is provided with insulation
Protective layer 33, the transmission speed of the silver energy of layer 32 lifting lead wire 3, enables the electrical equipment of automobile to react in time, insulating protective layer
33 reduce the friction between heart elastic supporting pipe 2 and wire 3.
The material of conductor 31 is copper, reduces the production cost of the wire harness, and the material of hollow elastic supporting pipe 2 is rubber,
Further reduce and be in the extruding force that the wire 3 of bending part is subject to, the material of connection fixture 13 is rubber, enhances the line
The shock resistance of beam.
More than be exactly a kind of wire harness design feature and action effect, its advantage：It is connected firmly between fixture and protective case,
Prevent wire to be pulled because by external force, reduce and be in the extruding force that the wire of bending part is subject to.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
