Compared with the prior art, the invention has the advantages of tight contact, large contact area, small contact resistance and good hear radiation performance, greatly improves the circuit performance in large current transmission, and has simple assembly process.
Description
Technical field
The present invention relates to electric components, especially a kind of plug of power connector that is applicable to big current delivery between circuit board or motherboard and daughter board.
Background technology
In the interconnection of electronic circuit, power connector plays function served as bridge, give each components and parts in the circuit with current delivery, so the quality of bridge will directly influence the final performance of whole transmission circuit.In power connector, its contact exists very big difference with respect to signal contacting piece, the power supply contact need have higher requirement, it not only will have very low contact resistance, bigger contact area, area of dissipation, and when the power supply contact is assembled in the insulating base, good heat radiation, ventilation condition are arranged, and then satisfy heat minimizing and temperature rise control in the big current delivery process, reduce because big current delivery produces higher temperature rise to the electronic circuit Effect on Performance.
Yet it is little that plug of power connector of the prior art exists contact area, and resistance is big, the shortcoming of weak heat-dissipating, and especially temperature rise is higher in big current delivery process, has had a strong impact on circuit performance, and complex structure, and assembly technology is loaded down with trivial details, the manufacturing cost height.
Summary of the invention
The objective of the invention is a kind of plug of power connector of designing at the deficiencies in the prior art, it adopts corrugated contact terminal, and contact is tight and area is big, has further reduced contact resistance, and perfect heat-dissipating, improved the circuit performance of big current delivery greatly.
The object of the present invention is achieved like this: a kind of plug of power connector, comprise insulating base and at least one conductive unit, and be characterized in that insulating base is the rectangular block shape grafting body that is provided with several grooves side by side; Conductive unit is to be arranged on the identical contact terminal of two shapes on the insulating base; Contact terminal is the rectangular tab that is provided with radiating groove, and the one end is provided with several contact chips, and a side of contact terminal is provided with several pins, and pin and contact chip at right angles are provided with, relative in twos and parallel being plugged on the groove of contact terminal.
The both sides of described contact terminal are respectively equipped with the boss and the hangnail of pegging graft and locating with groove.
Described contact chip is a corrugated sheet, and several contact chips go to upper and lower wavy being crisscross arranged at an end of contact terminal.
Described radiating groove is bar shaped radiating groove and trisquare shape radiating groove.
Described contact chip is at least 2 wave structures that are crisscross arranged.
The upper and lower wall of described insulating base is provided with several rectangle ventilation holes and "T"-shaped ventilation hole.
The present invention compared with prior art has contact closely, and contact area is big, and contact resistance is little, and perfect heat-dissipating has been improved the circuit performance of big current delivery greatly, and simple for assembly process.

Embodiment
Consult accompanying drawing 1, the present invention includes; Insulating base 3 and at least one conductive unit 5, conductive unit 5 is to be plugged on side by side on the insulating base 3 by the identical contact terminal 2 of two chip architectures to form.Insulating base 3 is for being provided with the rectangular block shape grafting body of several grooves 33 side by side, and its upper and lower wall is provided with the ventilation hole 32 of several rectangles and "T"-shaped ventilation hole 31; Contact terminal 2 is stamping forming rectangular tab, the one end is provided with several contact chips 20, one side of contact terminal 2 is provided with several pins 22, contact chip 20 at right angles is provided with pin 22, relative in twos and parallel being plugged on the groove 33 of contact terminal 2, the both sides of contact terminal 2 are respectively equipped with the boss 213 and the hangnail 212 of pegging graft and locating with groove 33; Contact chip 20 is a corrugated sheet, and several contact chips 20 go to upper and lower wavy being crisscross arranged at an end of contact terminal 2; Contact terminal 2 is provided with bar shaped radiating groove 210 and trisquare shape radiating groove 211.
With specific embodiment, the present invention is further elaborated below:
Embodiment 1
Consult accompanying drawing 4, contact terminal 2 is stamping forming rectangular tab, the one end is provided with 3 contact chips 20, one side of contact terminal 2 is provided with several 4 pins 22, contact chip 20 at right angles is provided with pin 22, contact chip 20 is a corrugated sheet, and 3 contact chips 20 go to upper and lower wavy being crisscross arranged at an end of contact terminal 2; 3 contact chips 20 dock with socket, and 4 pins 22 dock with printed circuit board; The rectangular tab of contact terminal 2 is provided with several radiating grooves that are bar shaped 210 and is the radiating groove 211 of trisquare shape; The both sides of contact terminal 2 are respectively equipped with the boss 213 and the hangnail 212 of pegging graft and locating with groove 33.
Consult accompanying drawing 6 (a), the present invention is docked with socket 4 like this: two preceding convex closures 201 of conductive unit 5 complement each other to form first contact zone that docks with socket 4, two back convex closures 202 of conductive unit 5, second contact zone that then formation docks with socket 4 that cooperatively interacts, and the radial dimension of first contact zone is slightly less than the radial dimension of second contact zone.
Consult accompanying drawing 6 (b), conductive unit 5 is when docking with socket 4, and first contact zone at first plays guide effect, and at this moment it does not contact with the contact terminal 40 of socket 4.
