Description
[technical field]
The utility model relates to a kind of elastic probe, refers to a kind of elastic probe that is connected with circuit board especially.
[background technology]
Along with the progress of semi-conductor industry, the use of SIC (semiconductor integrated circuit) is also universal day by day, how being connected between reinforced company's fitting and the circuit board, provides the stabilization signal transmission quality, has just become considerable problem.
See also Fig. 5 and Fig. 6, a kind of web member comprise plug end 12 ', contact site 14 ' and is connected this plug hold 12 ' with the connecting portion 13 ' of contact site 14 ', wherein, connecting portion 13 ' is the hollow circuit cylinder of a two ends convergent.
Web member is immobilizated in the body 2 ' with accepting groove in the prior art, and it has two kinds with the connected mode of circuit board 3 ': one, by the mode of pushing web member is linked to each other with circuit board 3 '; Two, arrange through hole 31 ' by going up, web member is passed through hole 31 ' on the circuit board 3 ', thereby realize being connected of web member and circuit board 3 ' at circuit board 3 '.
Yet, the defective of this dual mode is: by the mode of pushing web member is linked to each other with circuit board 3 ', when the end 12 ' that plugs of web member is pushed circuit board 3 ' downwards, circuit board 3 ' has an anchorage force that makes progress to web member, in practical operation, must seek external force and come this anchorage force of balance, common way is bolt 4 ' is passed circuit board 3 ' and to lock onto on the body 2 ', so just need in the limited space of circuit board 3 ', arrange bolt hole, take the space of circuit board, the mode that use is pushed has also improved the height of body virtually, simultaneously because this web member does not have buffer action, when external force was depressed this web member, this web member self can not slow down the impact of being born when contacting with circuit board; By arrange through hole 31 ' on circuit board, with the mode that elastic probe links to each other with circuit board 3 ', circuit board internal layer distribution must be walked around through hole 31 ', and this has increased the difficulty of circuit board 3 ' internal layer distribution.
Therefore, be necessary to design a kind of web member to overcome above-mentioned defective.
[utility model content]
The purpose of this utility model is to provide a kind of web member that utilizes surface adhering method (SMT) to realize and electrically connecting with circuit board, i.e. elastic probe.
For achieving the above object, elastic probe of the present utility model comprises and plugs end, elastic and end of probe, elastic probe plug the affixed tin ball of end, make elastic probe carry out surface adhering and be connected by tin ball and circuit board.
Compared with prior art, elastic probe of the present utility model has following advantage: utilize the surface adhering method, making elastic probe pass through the tin ball directly is connected with circuit board, do not need bolt, saved the arrangement space of circuit board like this, do not need to arrange through hole on the circuit board yet, reduced the difficulty of circuit board internal layer distribution.Elastic probe has buffer action, and can slow down the impact that this elastic probe is born when contacting with the tin ball of circuit board, and provides a strength and on the electrical components that end of probe is pressed against be in contact with it.
