Description

Be connected wire termination connector

Technical field

A kind of end for the wire for being arranged on and needing to connect is the utility model is related to, the company conductive for realizing wire connection Connect device.

Background technology

In some power supply units, it is necessary to which wire carries out the transmission of electric energy such as on electric car, motorcycle vehicle.By institute Need the branch powered sometimes relatively more, this will be related to the connectivity problem of wire.Common wire connection is usually line Core is intertwined, and then insulating tape is wrapped up in order to avoid leaking electricity in periphery.But this connected mode is over time, it is used Security is relatively poor, particularly applies on electric car or motorcycle, due to jolting for vehicle gall easily insulating tape, Loosen, the connection end of wire core also easily loosens, and causes electric leakage or the appearance of breaking phenomena.

Also occur realizing the connector that wire termination is connected in some supply lines, be provided with this connector Cylindric socket and the plug of cylinder, the wire core of socket and plug respectively with needing to link together are connected to one Rise, be plugged into by plug in socket to realize the connection of wire.But in this connector, due to only relying on plug and socket Grafting coordinates and realizes that two wires are conductively connected, and the anti-flexibility of socket in itself can not possibly be very big, is otherwise not easy to realize plug Grafting with socket coordinates.This connector in use, over time, due to connector during use Stability is relatively poor, and the fitness of socket and both plugs is small, and releasing between plug and socket even occurs sometimes.If Plug and socket fitness are poor, when realizing high current power supply, spark are also easy to produce between plug and socket and socket is carried out Ablation.And after plug and socket release, then open circuit conditions occur.Therefore, the stability in use of such connector is poor.

Utility model content

The utility model technical issues that need to address：One kind is provided to be connected wire termination connector, the connector Stability in use is good, the requirement for the conduction that is content with very little.

To solve the technical problem, the technical solution of the utility model：One kind is connected wire termination connector, including Split type fittings body, fittings body include two bodies, and the end of wire core is connected with conduction contact chip, and its feature exists In wire is plugged in fittings body in pairs, and contact chip is made into annular and in the connecting cavity of fittings body interior sealing, a centering Two wires be respectively provided at the corresponding positions of two bodies, the outer end of contact chip is relative to each other on two wires, for Along two body closures, elasticity approaches and is conductively connected respective wire each other when two bodies link together.

Two bodies can be connected together along two body closures described as follows, can also pass through fixing bolt edge The axial direction of wire tightens together two bodies.The elasticity, which approaches, to be referred to：Realize two bodies be connected operation when, ring Shape contact chip has certain elastic deformation in itself, and causes flexible active force between two contact chips.Two contact chips Outer end can be direct contact or set pad in panel described as follows, therefore both mutually approach.

Further, interface arrangment is respectively formed with the opposite sides of fittings body thickness direction, interface arrangment is used to make Two bodies are connected together in the axial direction of wire.By setting interface arrangment so that conveniently realize between two bodies It is connected, and connective stability is good.

Further, the interface arrangment includes the Jiong shape buckle being molded on a body and is molded over another body The dop of end, dop are plugged in buckle.Buckle and dop are integrally formed on each corresponding body respectively, are passed through Buckle and dop form described interface arrangment, and simple in construction, connective stability is good, and in easy to disassemble.

Further, buckle and dop are multiple that wire is in the interval between adjacent two buckle, the phase on body Pressure head is formed between adjacent dop, pressure head is plugged in the interval between adjacent buckle and is crimped on wire.By setting pressure head, Wire can be crimped, ensure the stability of wire, also make it that connector monnolithic case is attractive in appearance.And so that connector Good airproof performance, in order to avoid extraneous rainwater or dust is entered in connecting cavity.

Further, connecting cavity is four prisms cylinder, and two bodies are between the two formed with positioned at connecting cavity diagonal plane direction On mating surface.By setting inclined mating surface so that the connectivity robustness between two bodies is good, and is easy to two bodies Between grafting coordinate.

Further, contact chip has the fixing end being connected with wire and the free end extending at position fixed ends. So-called free end, refer to not weld between the end and the fixing end of contact chip, when contact chip is pressurized, free end can have Certain position it is mobile and to adapt to the compression of contact chip, consequently facilitating the deformation of contact chip, also allows for the bullet between two contact chips Property contact.

Further, the part that contact chip self-retaining end is stretched out is resisted against on the side wall of connecting cavity, two of a centering The free end of contact chip on wire is arranged symmetrically on connector thickness direction.It is corresponding to contact chip by connecting cavity side wall It is partial against so that realizing the elastic deformation of being easy to contact chip during the connection of two bodies.

Further, the outer end of contact chip is formed with flat face.By forming face, two are can effectively ensure that Contact area between contact chip, contribute to stable conduction.

Further, pad is provided with the face.Pad is also electric conductor in itself, and pad can be selected relatively Soft material, such as scale copper or tin piece, consequently facilitating the contact between two contact chips is stable.

Further, the face is obliquely installed relative to the midsagittal plane of connection body thickness.The midsagittal plane refers to perpendicular to even The section of junctor thickness direction.By being obliquely installed for face, it can further increase the contact area between two contact chips.

Therefore, the beneficial effects of the utility model：By the contact that annular is set between two wires for needing to connect Piece, when realizing connection for two bodies so that contact chip is pressurized along two body closures and the deformation of elasticity occurs, and two In the presence of natural resiliency power, contact stabilization between the two can ensure contact chip.Moreover, because two contact chips each other by Pressure, in compression deformation process, the part that they are in contact can form an adaptive resistance surface, can effectively ensure that two contacts Compactness between piece, so as to ensure that conductive demand, the demand of conducting heavy current can be well adapted for.So that contact chip position In in the connecting cavity of sealing, the external world will not pollute to contact chip so that the conductive effect between contact chip can ensure. When realizing that wire is conductively connected, by making two bodies link together, you can realize the quick electrical connection of wire termination, this company It is easy to operate to connect device.
