Description
Technical field
The utility model relates to the oil sprayer wire harness protective gear.
Background technique
The both positive and negative polarity of existing engine fuel injector is made of two M4 bolts; Two leads that oil sprayer wire harness is attached thereto needed to put on respectively rubber sheath before crimping nut terminal, then crimping nut terminal.
The existing lead of this rubber sheath protection oil sprayer wire harness and the problem that the nut terminal exists of adopting is: inconvenient operation, the lead of oil sprayer wire harness just need be put on rubber sheath before crimping nut terminal.In order to stay the operating space to crimp type terminal, rubber sheath can't be used for the end of crimping nut terminal near lead through the position on the lead, and rubber sheath is apart from about the wire termination 100MM.Behind the crimp type terminal, rubber sheath is pulled to the terminal root.After the wire harness assembling, two lines that link to each other with oil sprayer come out from a branch simultaneously, all have rubber sheath on the lead, so two rubber sheath roots can't link into an integrated entity with bellows in the branch.
When the production of oil sprayer wire harness, need simultaneously 50 leads of a bundle to be put on rubber sheath according to the oil sprayer wire harness production procedure.In actual mechanical process, the one, have unavoidably and leak the lead of wearing rubber sheath; The 2nd, the lead of having worn behind the rubber sheath needs crimping nut terminal, has rubber sheath to come off in the process that material moves unavoidably; The 3rd, rubber sheath has can be by instead through on the lead; Need the operation of doing over again after these several situations press down the connected nut terminal, the nut terminal is cut calcellation, puts on back crimping nut terminal from newly wearing rubber sheath, causes the waste of material and man-hour.
When oil sprayer wire harness was installed by engine works, the oil sprayer wire harness lead of putting on rubber sheath respectively, need be dug the rubber sheath head with after wire harness nut terminal is connected at the oil sprayer both positive and negative polarity, firmly forward the rubber sheath head is anchored on the nut terminal.What this process was leaned on is the elasticity of rubber, so require great effort very much.Because rubber sheath need be anchored to forward on the nut terminal, stays the space between the afterbody of rubber sheath and the bellows, will expose lead, does not have the effect of guardwire.
At one is exactly to adopt rubber material, owing to be subjected to the temperatures involved of motor and the influence of greasy dirt, rubber sheath is aging easily, and the time is once the long effect that does not have protection.(rubber sheath manufacturer: Yadong, Shenzhou City rubber product factory, address: the Wang Jiajing of Shenzhou City town, postcode 053873)
Summary of the invention
In order to solve the problem that existing oil sprayer wire harness adopts the rubber sheath protection to exist, the utility model provides the oil sprayer wire harness protective gear.
