Abstract
The utility model discloses a high-current power supply connector which comprises an insulating seat and contact terminals. The high-current power supply connector is characterized in that the insulating seat is a flat rectangular body provided with a plurality of slots; the contact terminals are two contact pieces in the same shape clamped on the insulating seat; the contact pieces are elastic strip sheets; one end of each elastic strip sheet is provided with an arc-shaped contact point, the other end of each elastic strip sheet is provided with a bent structure, and the middle of each elastic strip sheet is provided with a positioning member; and the contact pieces are embedded on the slots opposite to each other pairwise to form the power supply connector with a plurality of contact terminals. Compared with the prior art, the high-current power supply connector has the advantages of compact contact, large contact area, small contact resistance, good heat-radiating performance, simple assembly process and convenient use, and greatly improves the performances of the circuit for high-current transmission.
Description
Technical field
The utility model relates to electric components, especially a kind of large-current electric source connector that is applicable to that cable clamp, shell fragment terminal, copper bar and flat parts connect.
Background technology
In the interconnection of electronic circuit, power connector is requisite components and parts in the power circuit interconnection system.The contact terminal 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 how to reduce conductor resistance, increasing heat radiation is the key of big electric current connected system design, and it 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.
The utility model content
The purpose of this utility model is a kind of large-current electric source connector that designs at the deficiencies in the prior art, it adopts the tight and big contact terminal of area of contact, further reduce contact resistance, and perfect heat-dissipating, improved the circuit performance of big current delivery greatly.
The purpose of this utility model is achieved in that a kind of large-current electric source connector, comprises insulating base and contact terminal, is characterized in that insulating base is the flattened rectangular body that is provided with several slots, and contact terminal is to be fastened on the identical contact chip of two shapes on the insulating base; Contact chip is that an end is provided with arc shaped contact, the other end is provided with bending structure and the middle elasticity strip thin slice that is provided with keeper; Contact chip is embedded in the power connector of forming several contact terminals on the slot in twos relatively mutually.
Described keeper is bur shape or hole shape bayonet socket.
The utility model 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, and the user is easy to use.

Embodiment
With specific embodiment, the utility model is further elaborated below:
Consult accompanying drawing 5, form contact terminal 2 by contact chip 3 facing each other, the arc shaped contact 31 on its termination can be carried out current delivery with the crimping of sheet contact, and 35 liang of flat structures of tail end are close together mutually and can carry out current delivery with the crimping of Elastic Contact terminal.
The utility model is the embodiment of hole shape limited bayonet contact chip
Consult accompanying drawing 6, the present invention is made up of insulating base 1 and contact terminal 2, and insulating base 1 is for being provided with the flattened rectangular body of six slots 11, and contact terminal 2 is for being fastened on the contact chip 3 that two shapes are identical on the insulating base 1; Contact chip 3 is that an end is provided with arc shaped contact 31, and the other end is provided with bending structure 32, and the centre is provided with the elasticity strip thin slice of hole shape limited bayonet 34; Contact chip 3 is embedded in the power connector of forming three contact terminals 2 on the slot 11 in twos relatively mutually, and pin 4 is fastened on contact chip 3 on the cell wall of slot 11 by hole shape limited bayonet 34, stops contact chip 3 from slot 11 interior landings.
Consult accompanying drawing 7, contact chip 3 is that an end is provided with arc shaped contact 31, the other end is the tail end 35 that is provided with bending structure 32, the top of bending structure 32 is provided with hole shape limited bayonet 34, contact chip 3 is stamped to form by flexible conductive foil, form contact terminal 2 by contact chip 3 facing each other, the arc shaped contact 31 on its termination can be carried out current delivery with the crimping of sheet contact, and 35 liang of flat structures of tail end are close together mutually and can carry out current delivery with the crimping of Elastic Contact terminal.
More than just the utility model being further described, is not in order to the restriction this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
