Description
Technical field
The utility model belongs to automobile manufacturing field, especially relates to a kind of Novel wire harness connectors connecting for automotive wire bundle.
Background technology
Automotive connector is part important in automotive wire bundle, is to ensure the interconnective interface of appliance chamber, and it is by metal terminal and ensure that the fixing plastic sheath of metal terminal forms, and it is the hinge of the normal work of car load electric device system.Existing automotive connector is in order to ensure the good of electrical connection properties, terminal material is all used copper metal material, ensure contact performance by separable contact portion by the elasticity of metal, in order to ensure both sides' contact resistance minimum, in design, the elasticity of the elastic sheet metal of separable contact is accomplished very large, so cause the insertion of terminal and the power of extracting very large.But universal along with human engineering, and American Standard USCAR has clearly specified the manual various insertion force standards of people.Traditional dongle configuration is difficult to meet as above requirement, and therefore automotive connector producer is by restructuring or material means keeps contact engaging and separating force and contact performance balance.
Chinese Patent Application No. is 201320228830.0 to disclose a kind of Novel wire harness connector, comprise the front end component, middle-end parts and the back-end component that connect successively, described middle-end components interior is provided with terminal connection part part, and described terminal connection part part comprises more than one terminal splicing position; It is the cavity in inserting terminal hole that described front end component and back-end component are an end opening other end, and described middle-end parts are cavitys of both ends open, and described front end component and back-end component insert respectively middle-end parts and link position is respectively equipped with lockable mechanism.Use loop although above-mentioned patent has increased connector, greatly saved product quantity, reduced the layout worry of bringing because sheath is little, each parts connect by tight fit mode, so contact engaging and separating force is still very large, and the efficiency of impact assembling.
Utility model content
The purpose of this utility model is to provide a kind of wiring harness plug-in connector, and having solved existing connector affects the problem of efficiency of assembling because contact engaging and separating force is excessive, although can also ensure that contact engaging and separating force reduces simultaneously, contact performance is still good.
The utility model solves the technical scheme that its technical problem adopts: a kind of wiring harness plug-in connector, comprise the first connector and second connector of a pair of mutual grafting, described the first connector is provided with terminal, the second connector is provided with the spliced eye coordinating with described terminal, described terminal and spliced eye matched in clearance; Described the second connector inside is positioned at spliced eye below place and is equiped with the first elastic sheet metal, described the second connector inside is positioned at spliced eye top and is provided with the second elastic sheet metal, the outer wall of the second connector is provided with through hole, is mounted with the press mounting structure connecting with this second elastic sheet metal in through hole.When terminal inserts after spliced eye, press press mounting structure, make the second elastic sheet metal generation deformation and push terminal, ensure that the first elastic sheet metal, the second elastic sheet metal fully contact with terminal, reach the object of electrical connection.
Further, press mounting structure comprises press section, makes the abutting part of the second elastic sheet metal generation deformation, and makes the second elastic sheet metal maintain the tight lock part of deformed state.
Peg graft for convenient, the end of terminal is provided with chamfering.
Further, between the first connector and the second connector, be provided with avoiding misinsertion location notch.
The beneficial effects of the utility model: the utility model reduces the insertion force of connector by the distance expanding between spliced eye and terminal, and press press mounting structure and ensure the good contact of terminal and the first elastic sheet metal, the second elastic sheet metal.The utlity model has with low cost, convenient for assembly, the advantage that contact performance is good, the demand of realistic production.
Below with reference to drawings and Examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram that coordinates of press mounting structure and the second elastic sheet metal before inserting.
Fig. 3 is the schematic diagram that coordinates of press mounting structure and the second elastic sheet metal after inserting.
Embodiment
Embodiment, sees also Fig. 1 to 3, a kind of wiring harness plug-in connector, comprise the first connector 1 and second connector 2 of a pair of mutual grafting, the first connector 1 is provided with terminal 3, the second connectors 2 and is provided with the spliced eye 4 coordinating with terminal 3, terminal 3 and spliced eye 4 matched in clearance; Described the second connector 2 inside are positioned at spliced eye 4 below places and are equiped with the first elastic sheet metal 5, the second connector 2 inside are positioned at spliced eye 4 tops and are also provided with the second elastic sheet metal 6, the outer wall of this second connector 2 is provided with through hole 7, is mounted with the press mounting structure 8 connecting with this second elastic sheet metal 6 in through hole 7.When terminal 3 inserts after spliced eye 4, press press mounting structure 8, make the second elastic sheet metal 6 that deformation occur and push terminal 3, ensure that terminal 3 fully contacts with the first elastic sheet metal 5, the second elastic sheet metal 6, reach the object of electrical connection.
Press mounting structure 8 comprises press section 81, makes the second elastic sheet metal 6 that the abutting part 82 of deformation occur, and makes the second elastic sheet metal 6 maintain the tight lock part 83 of deformed state, and concrete, this tight lock part 83 is a back-off.The end of terminal 3 is provided with chamfering.Between the first connector 1 and the second connector 2, be provided with avoiding misinsertion location notch.
The utility model reduces the insertion force of connector by the distance expanding between spliced eye and terminal, and presses press mounting structure and ensure the good contact of terminal and the first elastic sheet metal, the second elastic sheet metal.The utlity model has with low cost, convenient for assembly, the advantage that contact performance is good, the demand of realistic production.
