Abstract
The invention discloses a contact spring coil in a power connector, which comprises at least two contact sheets (10) extending to a distal end, wherein a narrow groove (11) is formed between the contact sheets (10), each contact sheet (10) is provided with a distal end circular arc contact region (110) protruding outwards slightly and a proximal end circular arc contact region (111) retracting inwards slightly, and a tail end of the contact spring coil (1) connects a plurality of contact sheets (10) into a whole via a connecting strip (12). The contact spring coil (1) is an axially opened semi-closed cylindrical structure. The connecting strip (12) is connected with the contact sheets (10) via a circular arc transition region (13). The contact spring coil (1) is a thin elastic copper alloy formed by punching and circle curling. The contact spring coil is used in a jack of the power connector in order to be reliably connected with a pin in cooperation with the jack, can meet the requirements of the power connector on high density and miniaturization, and is reliable in contact, low in cost, capable of mass production and great in practical value.
Description
Technical field
The present invention relates to the power connector technical field, relate in particular to the contact spring coil in a kind of power connector.
Background technology
In the electronic circuit interconnection, power connector is requisite components and parts in the power circuit interconnection system, and its quality will directly influence the performance of whole transmission circuit.
Following power connector development trend must be miniaturization, high density, therefore how to reduce the contact contact resistance under limited area of dissipation environment and highly reliable contact becomes particularly important.
In order to improve the current delivery ability, power connector generally adopts the method that increases area of dissipation, strengthens material thickness, but will satisfy miniaturization, highdensity requirement, and the increase scope of contact area of dissipation just becomes very limited.Therefore, usually adopt another kind of method: by changing the purpose that the performance of material own realizes big current delivery, promptly adopt high-conductivity copper alloy, reduce contact resistance, improve the ability of transmission current, and then the heat that satisfies in the big current delivery process reduces and temperature rise control, reduce since the higher temperature rise that electric current produces to the electronic circuit Effect on Performance.
Yet, have high electrical conductivity can material, its elasticity is very poor, is easy to take place plastic deformation, has proposed a difficult problem for the connector contact reliability.Therefore, how to guarantee that the contact contact reliability has just become the key point of high density, miniaturization, power connector.
Summary of the invention
The objective of the invention is: the spring coil of the contact in a kind of power connector is provided, and it can satisfy the demand of power connector high density, miniaturization, and contact is reliable, with low cost, can realize producing in enormous quantities, has good practical value.
Technical scheme of the present invention is: the contact spring coil in a kind of power connector, it comprises at least two contact chips to remote extension, form narrow groove between the contact chip, each contact chip is provided with the far-end circular arc contact zone of outside slightly drum, the near-end circular arc contact zone that inwardly slightly shrinks, and contact spring coil tail end connects into an integral body by connecting band with a plurality of contact chips.
Below technique scheme is further explained:
Described contact spring coil is the semiclosed tubular construction with an axially open.
Described connecting band links to each other by one section arc transition district with contact chip.
Described contact spring coil is that slim elastic copper alloy band is by punching press, the moulding of volume circle.
Advantage of the present invention is: the present invention is applied in the power connector jack, in order to cooperate jack reliably to be connected with contact pin, jack and the relatively poor problem of contact pin high-conductivity copper alloy elastic properties of materials have been overcome, it is simple in structure, with low cost, can satisfy the reliability requirement of high density, miniaturized electric source connector fully.The present invention is with low cost, can realize producing in enormous quantities, has good practical value.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, as shown in drawings, the identical identical parts of label representative, for clear and explanation easily, accompanying drawing is not drawn in proportion, explains on the principle of the present invention but lay stress on.The present invention is not limited to accompanying drawing shown various accurate arrangement and means.

Wherein: 1 contact spring coil; 10 contact chips; 11 narrow grooves; 12 connecting bands; 13 arc transition districts; 110 far-end circular arc contact zones; 111 near-end circular arc contact zones; 2 jacks; 20 guiding surfaces; 21 grooves; 22 circular holes; 3 contact pins.
Embodiment
Embodiment: as shown in Figure 1, contact spring coil in a kind of power connector, comprise at least two contact chips 10 (being three contact chips 10 in the present embodiment) to remote extension, form narrow groove 11 between the contact chip 10, each contact chip 10 is provided with far-end circular arc contact zone 110 and near-end circular arc contact zone 111, and contact spring coil 1 tail end connects into an integral body by connecting band 12 with a plurality of contact chips 10.Connecting band 12 links to each other by one section arc transition district 13 with contact chip 10.
As shown in Figure 2, contact spring coil 1 is to be formed by very thin copper alloy belt punching out, volume circle, comprises three contact chips 10 that stretch out to far-end, and they are interconnected into an integral body at near-end mutually by connecting band 12.
The situation of installing and using such as Fig. 3, Fig. 4, shown in Figure 5 of contact spring coil 1, contact spring coil 1 is installed in the circular hole 22 on the jack 2, and the guiding surface 20 on the circular hole 22 provides good guiding for contact spring coil 1.Connecting band 12 just in time is stuck in the groove 21, so just defines moving axially of contact spring coil 1, and connecting band 12 contacts with groove 21 sidewalls simultaneously, and the far-end circular arc contact zone 110 on the contact spring coil 1 closely is connected with circular hole 22 sidewalls equally.
Contact spring coil 1 is packed into behind the jack 2, and form two places and closely contact before and after it: near-end is that connecting band 12 contacts with groove 21 inwalls, and far-end is that far-end circular arc contact zone 110 contacts with the inwall of circular hole 22.
As Fig. 4, shown in Figure 5, when jack 2 docks with contact pin 3, contact spring coil 1 is near-end circular arc contact zone 111 with the contact site of contact pin 3, so just form: contact pin 3 one sides directly contact as shown in Figure 5 with jack 2 madial walls under the elasticity extruding of contact spring coil 1, form long line contact, increase contact area, reduced contact resistance; Contact pin 3 opposite sides then with contact spring coil 1 on near-end circular arc contact zone 111 contact, guaranteed the contact reliability of connector.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present invention, rather than restriction.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
