Abstract
The utility model discloses a fuel injector wire harness leak-proof structure, which comprises a connector assembly support, a connector assembly and a cylinder cover hood, the lower end of the connector assembly support is fixed and mounted on a cylinder cover; a punch hole matched with the connector assembly support is arranged on the cylinder cover hood, and when the connector assembly support is mounted on the cylinder cover, the connector assembly support penetrates through the punch hole on the cylinder cover hood; and a connector assembly hole is arranged in the middle of the connector assembly support, and the connector assembly penetrates through the connector assembly hole from the connector assembly support. The utility model has the advantages of convenient installation and reliable sealing, and is applied to engines that need to lead the fuel injector wire harness out from the cylinder cover hood.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to a kind of oil sprayer wire harness sealing configuration.
Background technique
At present, adopt the motor of electric-controlled fuel injector.Generally be that valve mechanism cover is divided into two-section, the following half of the design of Sealing Structure of oil sprayer wire harness in valve mechanism cover; The perhaps direct fairlead of design wire harness on the block-head cylinder housing, nearby the auxiliary assembly technology window of design is so that installation wiring, and the outer wire harness of valve mechanism cover also is provided with draw ring; Again or on cylinder head, design the sealing configuration that wire harness is done on an edge.There are leakage of oil hidden danger in above-mentioned these methods or complex structure, or the assembling difficulty, and outward appearance is relatively poor.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of brand-new oil sprayer wire harness sealing configuration, and this structural design need not be done big change to valve mechanism cover or cylinder head in valve mechanism cover, simple and reliable for structure, and is easy for installation quick.
The utility model oil sprayer wire harness sealing configuration comprises connector assembly support, connector assembly and valve mechanism cover, and connector assembly support lower end is fixedly mounted on the cylinder head.Described valve mechanism cover is provided with the perforation that cooperates with the connector assembly support, and when the connector assembly support was installed on the cylinder head, described connector assembly support passed the perforation on the valve mechanism cover.The centre of connector assembly support is provided with the connector assembly hole, and connector assembly passes from the connector assembly hole of connector assembly support.
Connector assembly is provided with O shape ring recess, and connector assembly support upper end external cylindrical surface is provided with O shape ring recess.Between connector assembly and the connector assembly support, all use seal with O ring between connector assembly support and the valve mechanism cover.
The connector assembly support is provided with the connector assembly anti-rotation groove, and the connector assembly end is provided with the anti-rotation tongue, and assembling back anti-rotation tongue inserts in the anti-rotation groove, prevents the rotation of connector assembly.
Connector assembly support bottom is provided with positioning pin hole, be used for and cylinder head between the location.
The connector assembly front end is provided with the stop clip draw-in groove, is used to install stop clip, and connector assembly support perforation next door is provided with the stop screw hole, is used to install stop screw, and stop screw carries out spacing to stop clip.
The connector assembly cylindrical is provided with O shape ring recess, is used to install O-ring seals.The connector assembly end is provided with the spacing conical surface.
During installation, the connector assembly support is installed on the cylinder head, and O-ring seals is loaded onto in its upper end, the wire harness connector assembly is loaded onto O-ring seals, the connector assembly connector assembly support of packing into, and valve mechanism cover puts the connector assembly support and also is installed on the cylinder head, clamp with clip and to insert part, load onto stop screw, promptly finish installation.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy for installation, sealing is reliable, and is specious.Be applicable to the motor that to draw oil sprayer wire harness in the valve mechanism cover.
