Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description.
embodiment one.
Extremely shown in Figure 3 like Fig. 1; A kind of hat spring of the utility model; Comprise being dolioform hat spring body 1, said hat spring body 1 is provided with opening 11, and said hat spring body 1 is provided with some reeds 12; Offer through hole 13 between adjacent two reeds 12, every said reed 12 is provided with at least two contact sites 2 along hat spring body axis direction depression.
Every reed 12 is provided with at least two contact sites 2 along hat spring body axis direction depression, and when public pin 3 inserted hat spring body 1, the contact site 2 of reed 12 can be close on the public pin 3 like this; Realize reliable connection of public pin 3 and hat spring body 1, like this, at least two contact sites 2 of every reed 12 can form at least two contact points with public pin 3; Then be preced with spring body 1 and contact at least two contact rings of formation with public pin 3; Effectively increased the contact area of hat spring body 1 and public pin 3, guaranteed to be preced with fully contacting of spring and public pin 3, connective stability is strong; Can transmit big electric current, current delivery is stable and the contact engaging and separating force of public pin 3 and female pin 4 is evenly distributed.The hat spring of the utility model can be used for transmitting the big electric current of 20-500A, and laser propagation effect is good.The hat spring body that the hat spring body 1 of present embodiment is made for the beryllium-bronze material, durability is higher, can bear public female pin 4 plugs more than 10,000 times, and hat spring connector is more durable.
As depicted in figs. 1 and 2; As one preferred embodiment; Every said reed 12 is provided with two said contact sites 2; Two said contact sites 2 are respectively first contact site 21 and second contact site 22, and said first contact site 21 and second contact site 22 are arranged at intervals at the middle part of said reed 12.Every said reed 12 comprises epimere 121, stage casing 122 and the hypomere 123 that connects successively, and said first contact site 21 is arranged between epimere 121 and the stage casing 122, and said second contact site 22 is arranged between stage casing 122 and the hypomere 123.Particularly, first contact site 21 is positioned at the middle part of reed 12, and second contact site 22 is positioned at the middle and lower part of reed 12, in the present embodiment, is the top of reed 12 with top shown in Figure 2, is the bottom of reed 12 with below shown in Figure 2.Like this when public pin 3 inserts reed 12 bodies; Public pin 3 is at first with 21 contacts of first contact site; Public then pin 3 contacts with second contact site 22 again; Because said first contact site 21 is not less than said second contact site 22 and the distance of being preced with between the spring body axis with distance between the hat spring body axis, the internal diameter of first contact ring that is then surrounded by said first contact site 21 of some reeds 12 is not less than the internal diameter of second contact ring that said second contact site 22 by some reeds 12 surrounds, and guarantees that public pin 3 stably fixedly steps up in being preced with spring body 1; Connect and stablize, it is stable to transmit big electric current and current delivery.
In the present embodiment, during expansion, said hat spring body 1 rectangular or parallelogram.As shown in Figure 2, rectangular when hat spring body 1 launches, adjacent two reeds 12 are parallel to each other, and are convenient to machine-shaping, and production cost is low.
embodiment two.
Like Fig. 4 and shown in Figure 5, a kind of hat spring connector of present embodiment comprises public pin 3 and female pin 4; Said female pin 4 is provided with jack 41; Said public pin 3 is pegged graft with said jack 41 and is cooperated, and also comprises embodiment one described hat spring, and said jack 41 is provided with draw-in groove 411; The hat spring body 1 of said hat spring is arranged at draw-in groove 411, and said public pin 3 front ends are provided with insulation division 31.Further, the top of insulation division 31 is provided with the arc lead angle.
The hat spring connector of present embodiment needs lead is connected respectively the wiring rear end of public pin 3 and female pin 4 applicable to signal transmission and big current delivery before using, in the jack 41 of female pin 4, be provided with draw-in groove 411, and hat spring body 1 cutting ferrule is in draw-in groove 411; Hat spring body 1 offers opening 11, at hat spring body 1 and female pin 4 each other during assembling, thereby the reduced of hat spring body 1 is packed in female pin 4 easily and can not damage hat spring body 1, long service life.Public pin 3 need not to be connected through tolerance fit with female pin 4; The public pin 3 that hat spring body 1 leans on the elasticity pretightning force of self will insert wherein carries out fastening; Reduce the requirement on machining accuracy of public pin 3 and female pin 4 greatly; And contact engaging and separating force required when plugging public pin 3 and female pin 4 is littler, plug is more shown easily, and prolong the useful life of connector.
As shown in Figure 4; Public pin 3 front ends of present embodiment are provided with insulation division 31; The hat spring connector of present embodiment can be realized big current delivery, when public pin 3 and female pin 4 connect big electric current, can produce electric spark in touching moment; When the insulation division 31 of public pin 3 front end settings can prevent effectively that public pin 3 from contacting with female pin 4, produce electric spark, make hat spring connector use safer, reliable.
Every said reed 12 of present embodiment is provided with two said contact sites 2; Two said contact sites 2 are respectively first contact site 21 and second contact site 22; The internal diameter of first contact ring that is surrounded by said first contact site 21 of some reeds 12 is less than the external diameter of said public pin 3; Guarantee to be preced with spring body 1 and public pin 3 close fit, connect and stablize, current delivery stability is high.
The two ends of the hat spring body 1 of present embodiment offer distribution density breach inequality 14 respectively, and said draw-in groove 411 inwalls are provided with projection, and said projection matches with said breach 14.Draw-in groove 411 not only lets the hat spring more be prone to pack in female pin 4, and utilizes the cooperation of projection and breach 14 to install, and the distribution density of the breach 14 at hat spring body 1 two ends is inequality, thereby plays foolproof function, avoids public female pin 4 to be preced with spring through plug back repeatedly and is shifted.
The remainder of present embodiment is identical with embodiment one, repeats no more here.
Above content is merely the preferred embodiment of the utility model; For those of ordinary skill in the art; According to the thought of the utility model, the part that on embodiment and range of application, all can change, this description should not be construed as the restriction to the utility model.
