Abstract
A kind of plug contact terminal of power connector, this contact terminal comprises: butt end, the afterbody that is made of the pin that connects printed board, rise and connect and middle part that the sidewall of thermolysis constitutes, the butt end is provided with the butt joint sidewall that extends and have spacing from the middle part forward, this butt joint sidewall is by the different directions bending, form arc convex, the corresponding again butt joint convex closure that forms.When the plug contact terminal of employing said structure docks with the socket contact terminal, can form many lines contacts closely, and then increase the contact area of contact terminal, thermal diffusivity is good, improves the contact terminal contact reliability.The present invention is applicable in the power connector that carries out big current delivery.
Description
Technical field
The present invention relates to a kind of plug contact terminal of power connector, relate in particular to a kind of big electric current Elastic Contact terminal that is applied in the power connector that printed board installs.
Background technology
In the interconnection of electronic circuit, power connector is requisite components and parts in the power circuit interconnection system.The contact of relative transmission signals, the design that is applied to the big electric current contact terminal in the power connector is very crucial, because contact terminal is in the process of the big electric current of transmission, if contact resistance is bigger, can produce more heat, when these heats can't be in time, when distributing effectively, will produce very high temperature at regional area, cause the electrical property of power circuit to change.Therefore, must be able to dispel the heat, thereby the change of the result's who changes as electric current circuit performance is reduced as far as possible at the connector that is designed for power circuit.
Summary of the invention
The purpose of this invention is to provide a kind of big electric current printed board plug of power connector contact terminal that stable, heat-sinking capability is strong, be easy to process that connects.
The objective of the invention is to realize by following approach:
Plug contact terminal of the present invention comprises: the butt end that is used to dock, constituted and the afterbody that is used for being connected with printed board, risen and connect and middle part that the sidewall of thermolysis constitutes by pin, described butt end is provided with the butt joint sidewall that extends and have each other certain intervals from the middle part forward, form the circular arc projection of different directions on each butt joint sidewall by bending, the circular arc protrusion direction of all butt joint sidewall corresponding positions is opposite, forms the butt joint convex closure.
Above-mentioned contact terminal middle part is provided with two flexure strips that recede and stretch out.Circular arc projection on each butt joint sidewall of described contact terminal butt end can be 2-3 or more, and the butt joint convex closure of corresponding its formation is 2-3 or more therewith, increases the line contact quantity of butt end with this.
The invention has the beneficial effects as follows:
When plug, the butt joint of socket contact terminal, can form many line contacts closely, and then increase contact zone contact area and near area of dissipation, in big current delivery process, concentrate the heating energy that produces to arrive other non-key position of contact terminal in the contact zone by the rapid efficient transfer of heat conducting mode, finally distribute, reach and make reliable contact of contact terminal and purpose of connecting by radiation, mode such as air-cooled.

Among the figure: A, B-butt joint convex closure, 20-pedestal.
Fig. 3 is that another execution mode of the present invention has the structural representation of three butt joints during sidewalls.
Embodiment
The present invention is described in further detail below in conjunction with above-mentioned accompanying drawing.
Accompanying drawing 1 is a kind of execution mode structural representation of power connector contact terminal of the present invention.As shown in the figure, plug of power connector contact terminal of the present invention comprises butt end 11, middle part 12, afterbody 13, wherein, afterbody 13 comprises the pin 131 that is connected with printed board, middle part 12 has comprised the sidewall 121 of connection and thermolysis, 122, butt end 11 is provided with two butt joint sidewalls 111 that extend and have each other certain intervals from the middle part forward, 112, described two butt joint sidewalls respectively form 2 circular arc projectioies 1111 by the different directions bending, 1112 and 1121,1122, the circular arc protrusion direction of two butt joint sidewall corresponding positions is opposite, make circular arc projection 1111,1121 form the butt joint convex closure A of arcuate opposite, circular arc projection 1112,1122 form butt joint convex closure B.
The arc convex of described butt joint sidewall front end is less than the arc convex of rear end.
12 two sides 121,122, described butt joint terminal middle part are provided with the flexure strip 1211,1221 that tilts to stretch out to afterbody.It can limit the axial motion of contact terminal 1 when contact terminal 1 is packed the plasticity pedestal into, prevent that contact terminal 1 from taking place to deviate from phenomenon from the plasticity pedestal.
During this contact terminal butt joint, because circular arc projection 1111 is docked on the sidewall at same metal with 1112, circular arc projection 1121,1122 is in same metal pair contact pin, so by the butt joint convex closure A that forms opposite with the radial motion direction of butt joint convex closure B, when promptly docking convex closure B radial dilatation, butt joint convex closure A radial contraction, otherwise, during butt joint convex closure B radial contraction, butt joint convex closure A radial dilatation.
Butt joint convex closure A radial dimension is less, when contact terminal docks, butt joint convex closure A can play certain guide effect, when butt joint convex closure B contacts with butt end 20 sidewalls, butt joint convex closure B is by radial compression, make butt joint convex closure A radial dilatation, so just in time closely be adjacent to, form 4 line contacts closely with butt end 20 sidewalls.
Accompanying drawing 3 is another execution modes of the present invention, the structural representation when promptly having three butt joint sidewalls.When the contact terminal of the bigger rated current of needs, also can obtain the contact terminal of 6 or more line contact structures by the quantity that increases butt joint sidewall or convex closure.
