Description
Technical field
The present invention relates to a kind of conduction spring of the contact pin for power connector.
Background technology
In the power connector of transmission big current, contact used is divided into contact pin and jack, contact pin is used for being plugged in jack, the transmission of signal is realized with this, in actual use, in order to ensure the reliability of contact pin, jack grafting, jack is generally the elastic component with elasticity capacity, as open pore, line spring hole, string of a hat hole etc.Now for string of a hat hole, jack Problems existing in prior art is described, the structure in string of a hat hole as shown in Figure 1 and 2, comprise jack body 1 and be arranged at the hat spring 2 in the endoporus of jack body, multiple reeds 4 that hat spring comprises front circle 3, rear circle 5 and is connected between forward and backward circle, the middle part of each reed is protruded towards the centerline direction being preced with spring, therefore each reed is provided with the ability of radial deformation, when contact pin and jack grafting, contact pin passes through by the gap between each reed, and the middle part of each reed contacts with contact pin and coordinates thus conducting contact pin, jack.In order to realize contact pin, the reliability of jack grafting, the elasticity position of reed can only be made to contact with contact pin, other are several, and to have the jack of elasticity capacity also similar, this just causes very limited of the contact area between jack and contact pin, contact resistance between jack and contact pin is larger, jack, the through-current capability of contact pin is limited, in order to improve contact pin, the through-current capability of jack, contact pin can only be increased by the diameter increasing contact pin, contact area between jack, this will cause the overall volume of corresponding power connector also larger, be unfavorable for the miniaturization of power connector, lightweight makes.
Summary of the invention
The object of the present invention is to provide a kind of conduction spring of the contact pin for power connector improving contact pin, jack contact area.
In order to solve the problem, technical scheme of the present invention is:
A kind of conduction spring of the contact pin for power connector, comprise extend in left-right direction for being fastened in the bar shaped flexible substrate of respective pins periphery in use, conduction spring also comprises multiple elasticity fingertip, the lower end of each elasticity fingertip is directly or indirectly connected with described bar shaped flexible substrate, the upper end of each elasticity fingertip is the elasticity projecting end with amount of elastic deformation in the longitudinal direction of the upside elasticity overhanging towards bar shaped flexible substrate, and the elasticity projecting end of each elasticity fingertip is provided with the contact site for coordinating with the hole wall Elastic Contact of corresponding jack.
Each elasticity fingertip is arranged along the bearing of trend interval of bar shaped flexible substrate.
Described elasticity fingertip is from the bottom to top gradually towards top rake, and the end, upper end of described elasticity fingertip is bent into recess arc elbow backwards, the contact site described in front end face formation of described arc elbow.
The lower end of each elasticity fingertip self-correspondingly to be protruded and location male member in the spiral positioning groove of positioning and plug-in mounting on described contact pin outer peripheral face is connected with described bar shaped flexible substrate backwards respectively by each.
On the bearing of trend perpendicular to bar shaped flexible substrate, the cross sectional shape of described location male member takes the shape of the letter U, the location male member of U-shaped comprises upper and lower sidewall and is arranged at the diapire of upper and lower sidewall rear end, and upper and lower sidewall connects with corresponding elasticity fingertip and described bar shaped flexible substrate respectively.
Described bar shaped flexible substrate, location male member and elasticity fingertip are one-body molded.
Described bar shaped flexible substrate is the slab organization that thickness extends along the longitudinal direction.
Beneficial effect of the present invention is: during use, bar shaped flexible substrate is fastened in the periphery of contact pin, bar shaped flexible substrate forms a circle, the structure of one circle, elasticity fingertip has elastic deformation amount in the longitudinal direction and refers to that elasticity fingertip can strain along the longitudinal direction, elasticity fingertip can swing when being subject to external force, insert in the process of jack at conduction spring with contact pin, the elasticity projecting end of elasticity fingertip is oppressed by the hole wall of jack and produces the distortion (swinging backward or forward rocking motion) on fore-and-aft direction, thus ensure the hole wall reliable contacts of contact site on elasticity projecting end and jack, ensure that the reliable of grafting, and often enclose on bar shaped flexible substrate all there is multiple elasticity fingertip, each elasticity fingertip on each circle bar shaped flexible substrate respectively with jack hole wall Elastic Contact, make to produce a lot of contact point between conduction spring and jack, the number of contact point is relevant with the number of turns of bar shaped flexible substrate with the spacing between adjacent two elasticity fingertips, theoretically, the number of contact point can be infinitely many, contact points a lot of like this adds the contact area of conduction spring and jack together, make the resistance between contact pin and jack less, thus larger electric current can be carried, do not need again the radial dimension increasing contact pin and corresponding connectors simultaneously, be conducive to the miniaturization of power connector, lightweight makes.
