Electric power connector.The first terminal and the Second terminal at least one of them have elasticity, make in the first connector grafting this
When two connectors, which is promoted with the Second terminal at least one of them using the moment stress that its elasticity absorption engages
Total reliability, but second ontology fixes contact or the Elastic Contact the first noumenon and plugs together group and connect.The first terminal with should
The front-end surface of Second terminal be in respectively between a horizontal plane have 18~45 degree angles sloped contact surface, and the first terminal and this
Second terminal is oppositely arranged.Alternatively, the front-end surface of the first terminal can be in convex arc shaped, and the front-end surface of the Second terminal is in
Concave arc shape and the front-end surface for corresponding to the first terminal.In a state sample implementation, the front-end surface of the first terminal is in convex arc shaped,
And the front end of the Second terminal connects the inclined-plane that ring sets multiple kenels, the inclined-plane of reversed dip is oppositely arranged two-by-two and is formed multiple
Angle vertebra and multiple chases.Again or, the first terminal front-end surface be in convex arc shaped, and the Second terminal front end connect ring set it is more
The convex globoidal of a kenel.
Also, the first noumenon and second ontology are done using made by polymer or conductive material with strengthening anti-electromagnetism
Disturb ability.Second ontology has the hole of at least more than one, and high molecular polymer or air are filled in the hole.
Increase between the first terminal front-end surface and the Second terminal front-end surface in conclusion the present invention compactly passes through
The technological means of contact area, meanwhile, when being engaged using the elastic moderation of the first terminal first connector with first connector
Moment stress so that the high-frequency electronic connector in addition to good high frequency characteristics with it is low engage fault other than, can more realize
Increase the advantages such as the plug number between connector, the high-frequency signal transmission quality for promoting total reliability and high stable.
