Abstract
The invention provides a circular contact spring slice material strip punching structure which comprises a material strip (20) and a plurality of circular contact spring slices (1) distributed on the material strip (20), wherein the circular contact spring slices (1) are provided with bendable extension parts (11) which are distributed along the texture direction of the material strip (20). In the scheme, the contact spring slices are distributed along the texture direction of the material strip, thus enhancing product functions and service lives.
Description
Technical field
The present invention relates to a kind of circular contact spring slice material strip punching structure, belong to machining manufacturing technology field.
Background technology
The contact flat spring of annular, promptly connector be shaped as annular, be applied in widely in the high-tech industry, as mobile phone, palmtop PC, digital camera and multimedia player or the like, the contact flat spring that is connected with the headset plug data commonly.This contact flat spring reaches the purpose of contact stabilization by cooperating with the really up to the mark of headset plug.For this reason, quite strict to the elastic force and the life requirements of contact flat spring, common life requirements is more than 5000 plugs.Technological requirement to this contact flat spring is to be made of metal, the first-selected phosphor bronze (C5210R-EH) of raw material, and its conducting property is strong, and hardness is between HV:210 ~ 260, and gold-plated processing in addition, make shell fragment can keep preferable elasticity, thus in use not yielding.
When preparing such circular contact spring slice, adopt vertical strip punching out mode usually, promptly whole terminal vertical distribution is on raw material, and punching out uniformly is formed with contact flat spring.But need to prove that in the existing strip punching out mode, contact flat spring all is vertical layout along strip, though can make more contact flat spring in the unit are upper punch of strip like this,, reduced the useful life of contact flat spring greatly.Reason is that strip itself also is through the metal material of processing, has metal material lines freely, if bend along lines, then can keep preferable shell fragment performance; Otherwise, if bend, then can significantly reduce the shell fragment performance perpendicular to lines, promptly can cause the shell fragment life-span short, the problem that the elastic force decay is fast.Such principle is just as bamboo, can very easily bamboo be split along the lines of bamboo disconnected, will be very difficult and vertically go to split.
Therefore, prior art is necessary further improvement in fact.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of circular contact spring slice material strip punching structure is provided, can be provided long useful life.
Purpose of the present invention is achieved through the following technical solutions:
A kind of circular contact spring slice material strip punching structure comprises strip and is arranged in some circular contact spring slices on the strip that circular contact spring slice has bent extension, and described extension is to arrange along the ridge orientation of strip.
Wherein,
Described circular contact spring slice is elongate shape, comprises main body, and described extension extends from an end of main body.On the described main body, be positioned at the both sides of extension, all link together by a terminal supportor and strip.Described terminal supportor is prejudged formula with being connected to of strip and is connected.
Helpfulness effect of the present invention is: by contact flat spring is arranged along the ridge orientation of strip, improved product function and useful life.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1 is the expansion schematic diagram of circular contact spring slice among the present invention.
Fig. 2 is the end view of circular contact spring slice.
Fig. 3 is the schematic diagram of circular contact spring slice material strip punching structure among the present invention.
Related elements reference numeral in the diagram is as follows:
1, circular contact spring slice 10, main body 11,12, extension
13,14, terminal supportor 20, strip
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, circular contact spring slice 1 is elongate shape haply, comprises main body 10 and distinguishes extended extension 11,12 from the two ends of main body 10, and one of them extension 11 can bend, and plays the effect of shell fragment.See also Fig. 2, after extension 11 bending, will with main body 11 near and wholely constitute a U type.
See also Fig. 3, such circular contact spring slice in the preparation, employing be a kind of strip punching structure of circular contact spring slice, promptly on a whole piece raw material belt 20, punching out uniformly is formed with some contact flat springs 1.But need to prove that these contact flat springs 1 all are to arrange along the ridge orientation A of strip 20, promptly arrange along the direction of strip 20.Wherein, on the main body 10 of each contact flat spring 1, be positioned at the both sides of extension 11, all link together by a terminal supportor 13,14 and strip 20.
Need to prove that terminal supportor 13,14 is prejudged formula with being connected to of strip 20 and is connected, promptly the user needs only the bending contact flat spring 1 that passes through gently, just strip 20 and contact flat spring 1 can be separated and is normally used.
This programme is by arranging contact flat spring along the ridge orientation of strip, product function and useful life have been improved, through life test, the traditional product shell fragment elastic force life-span can only reach 3500 times and 1000 elastic force of every plug are decayed with 20%, and the life of product of this programme production can reach more than 7500 times and 1000 elastic force of every plug are decayed with 3%, the result is far longer than market demands, and its profit potential is very big.
