Set, screen layer and connector three parallel laying from inside to outside, by crimping on the connectors, not only realize adapter sleeve and connection
The firm connection of device and wire harness, and ensure that screen layer and adapter sleeve, effective contact area of connector, when avoiding crimping pair
Wire harness produces larger damage, pressure-resistant few, is not easy to puncture；Adapter sleeve length only need to be identical with lower body, needs not extend to
On the outside of wire harness, the making material of adapter sleeve is saved, has reduced the production cost of adapter sleeve.
Further, the shielding layer segment is in the wire harness, and the part of screen layer, which extends to bend after wire harness, to be inserted down
Between portion's body and adapter sleeve.Shielding layer segment is stretched into wire harness, and part bending is set on the outside of wire harness, its one side and adapter sleeve
Contact, opposite side contact with the inwall of connector, and not only attachment structure is firm, and the contact with connector and adapter sleeve is more
Fully；And when connector outer wall crimps, due to more, thicker protective layer, being not damaged inside wire harness, become
Shape is few.
Further, the shell one end offsets with connector, and the housing end is provided with first seal.
Further, the portion of upper body is provided with lower limit convex edge, and the first seal offsets with the lower limit convex edge.
Further, the first seal includes inner sealing surface and the external seal face that can coordinate with housing, described outer close
Front cover includes multiple sealing rings be arrangeding in parallel.First seal is it is possible to prevente effectively from the water inlet of electric machine controller shell, ring-type knot
Structure somewhat to have deviation between first seal and electric machine controller shell it is also ensured that sealing effectiveness
Further, the portion of upper body is provided with the upper limit convex edge for being used for preventing that elastic component from departing from.
Further, the shell one end is connected by second seal with wire harness, and the stop collar is by second seal
It is butted in housing.Assembly technology is simpler, and linkage editor is simplified, and efficiency of assembling is higher.
Further, the stop collar is provided with opening portion, and the housing is provided with the buckle that can coordinate with opening portion, should
Buckle is provided with the inclined plane for being easy to slip into opening portion.
Further, the second seal includes the interior sealing wall that can coordinate with wire harness and can coordinated with housing outer close
Feng Bi.
Further, the lower body and adapter sleeve are crimped on wire harness.
The beneficial effects of the utility model are：Assembling structure simplifies, and production efficiency is high, and cost reduces, and shield effectiveness is good, no
Easily breakdown, water resistance is strong.
