On the vehicle frame of vehicle perhaps on engine on vehicle frame or engine can be released effectively the electric leakage on weak electric signal line, further
Ground, the signal interference processing terminal in the present embodiment can select the signal interference of intra-locomotive to handle terminal, can also select
The signal interference processing terminal additionally installed, signal interference processing terminal are connect with signal interference processor, below can be to ground wire
It is described in detail with signal interference processing terminal.It should be noted that ground connection described in the present embodiment not merely refers to shield
It covers layer 22 to connect with the earth, as long as can discharge the device to leak electricity on shielded layer 22 can be described as ground wire, such as in this implementation
Shielded layer 22 is connect with devices such as vehicle frame, engines in example can be described as being grounded.
With continued reference to Fig. 1 and Fig. 2, the first end 221 of each shielded layer 22 is connected to the body 30 of engine, each shielding
Layer 22 is grounded by body 30.
The present embodiment passes through engine by the way that the first end 221 of each shielded layer 22 to be connected to the body 30 of engine
Body 30 so that each shielded layer 22 is reached ground connection purpose, reduce the electric leakage on each branch's harness 20 and damage electric component occur
Phenomenon.Further, it due to being provided with multiple branch's harness 20 in exterior insulation protective case 10, is covered outside each branch's harness 20
Equipped with shielded layer 22, therefore, multiple shielded layers 22 are provided in exterior insulation protective case 10, in order to reduce on each branch's harness 20
Shielded layer 22 between there is interfering with each other phenomenon, the shielded layer 22 being arranged outside each branch's harness 20 is connected to by the present embodiment
The different location of body 30 reduces influencing each other between each shielded layer 22 with this.
With continued reference to Fig. 1 and Fig. 2, it is that the signal interference on ECU40 handles stitch 41, Mei Geping that signal interference, which handles terminal,
It covers layer 22 and filters interference signal by handling the signal interference processor that stitch 41 is connect with signal interference.
The present embodiment handles stitch by the way that the second end 222 of each shielded layer 22 is connected to the signal interference on ECU40
41, handling stitch 41 by the signal interference on ECU40 connect each shielded layer 22 with signal interference processor, reduces each point
There is the phenomenon that signal interference in branch harness 20.Further, due to being provided with multiple branch's harness in exterior insulation protective case 10
20, each branch's harness 20 is arranged with shielded layer 22 outside, therefore, multiple shielded layers is provided in exterior insulation protective case 10
22, there is interfering with each other phenomenon to reduce between the shielded layer 22 on each branch's harness 20, the present embodiment is by each branch line
The shielded layer 22 being arranged outside beam 20 is connected to signal interference processing stitch 41 different on ECU40, reduces each shielded layer 22 with this
Between signal influence each other.Further, the present embodiment also by multiple branch's harness 20 in exterior insulation protective case 10 into
Row share split, by forceful electric power branch harness 20 divide for one, light current branch harness 20 is divided for another stock, between two stock branch harness 20
It is separated by two layers or three layers of shielded layer 22, to reduce interference of the forceful electric power branch harness 20 to light current branch harness 20.
Fig. 3 is the arragement construction schematic diagram of the protected type engine wiring harness of one embodiment of the invention.
As shown in figure 3, according to an embodiment of the invention, protected type engine wiring harness further includes Wiring harness connector 50, harness
Connector 50 is set among protected type engine wiring harness, and further, Wiring harness connector 50 is set to enging cabin A and drives
On hatch door partition C between the B of cabin, for protected type engine wiring harness to be divided into engine bay section 11 and drives bay section 12.
Wiring harness connector 50 in the present embodiment can select Wiring harness connector common in market, connect to reduce harness
The harness section for connecing 50 both ends of device occurs disengaging phenomenon, and the Wiring harness connector 50 in the present embodiment uses blocking device, locking dress
Setting to be buckle structure, after the harness section when 50 both ends of Wiring harness connector is linked together by Wiring harness connector 50, harness
Two sections of harness are connected together by the buckle structure on connector 50, so that the harness for reducing Wiring harness connector both ends occurs each other
The phenomenon that disengagement, when dismantling Wiring harness connector 50, first has to unlocking device, then Wiring harness connector 50 is pulled open, together
When, not allowing to pull at harness in the case where non-unlocking causes blocking device or Wiring harness connector 50 to damage.Further
Protected type engine wiring harness is divided into engine bay section 11 by Wiring harness connector 50 and drives bay section 12 by ground, the present embodiment, when
When needing integral hoisting engine, protected type engine wiring harness can be disconnected at Wiring harness connector 50, reduce enging cabin A
The influence between driving bay section 12 in interior engine bay section 11 and cockpit B, so that staff be facilitated to repair engine.
Meanwhile Wiring harness connector 50 being set on the hatch door partition C between enging cabin A and cockpit B, it is possible to reduce protected type hair
Motivation harness is wearing the abrasion loss at wall.
With continued reference to Fig. 3, according to an embodiment of the invention, Wiring harness connector 50 is plug in construction and Wiring harness connector 50
On be provided with error-proof structure.
The present embodiment reduces 50 both ends harness of connection wiring harness connector by the way that error-proof structure is arranged on Wiring harness connector 50
Occur inconsistent phenomenon when connection, specifically, error-proof structure can be the groove being set on 50 outer wall of connection wiring harness connector or
Person's protrusion, user can pass through the groove or the raised line for making 50 both ends of Wiring harness connector on 50 outer wall of connection wiring harness connector
Beam is correspondingly connected with, and inconsistent phenomenon occurs during the connection process in the harness for reducing 50 both ends of Wiring harness connector.
With continued reference to Fig. 3, the second aspect of the present invention also proposed a kind of engine, and engine includes such as the present invention first
The protected type engine wiring harness of aspect, therefore, engine of the invention have all skills of protected type engine wiring harness of the present invention
Art effect, is no longer repeated herein.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
