Specific embodiment
The invention is further described with the following Examples.
Fig. 1 is the structural schematic diagram of spinning probe entirety.
See that Fig. 2, electric current needle are made of electric current syringe needle 1 and electric current shank 2, wherein electric current shank 2 is manufactured by brass, and electric current
Syringe needle 1 is formed by the skin Copper fabrication of high rigidity.In the bottom insertion electric current syringe needle 1 of electric current shank 2, the seam between the two junction
Gap is filled with thermite, and thermite specifically uses sweat soldering mode to pour into gap, and electric current syringe needle 1 is made to be fixed on electric current shank 2
Bottom.
Electric current shank 2 is cylindrical, is cased with slidable sleeve 8 on peripheral side, and there are two be not shown in the figure on sleeve 8
Screw installation counter sink by sleeve 8 be fixed to needle bed on.Two are provided on the peripheral side of electric current shank 2 symmetrically arranged to lead
The middle section of slot A, guide groove A tilt, and the both ends in the middle section are separately connected the upper vertical section for being parallel to own axes and lower vertical section,
Two pin B are stuck on two guide groove A of electric current shank 2.See Fig. 2, opened on sleeve 8 there are two the through-hole for running through sleeve,
Two pin B are embedded on sleeve 8 to close-fitting together through two through-holes respectively.Sheath 13 is stuck in the peripheral side of sleeve 8,
Through-hole is covered to prevent pin B from dropping out.The bottom of sleeve 8 is provided with circular accommodation groove 14.10 sets of reset spring in electric current
On the peripheral side of shank 2, one end is fallen into accommodation groove 14, and the other end withstands electric current syringe needle 1, to be sandwiched in sleeve 8 and electricity
It flows between syringe needle 1, when electric current syringe needle 1 presses battery electrode column, the elastic force of reset spring 10 makes electric current syringe needle 1 be pressed on battery pole
On column.
Electric current shank 2, which is located on the peripheral side at the position of 8 top of sleeve, is also cased with M6 nut 12 and stop nut 9, M6 spiral shell
Mother 12 is located at 9 top of stop nut.Stop nut 9 is locked with 2 peripheral side of electric current shank by screw thread, is equivalent to
One locating part blocks sleeve 8, and sleeve 8 is not allowed to pop up electric current shank 2 from top.M6 nut 12 is by being threaded onto electric current needle
On bar 2, and the current line of needle bed is closely clipped between M6 nut 12 and stop nut 9, effectively prevent wiring not tight or loose
The phenomenon that opening.
Electric current needle is dug out a circular hole channel along its axis, is inserted with a voltage needle 3 in circular hole channel, voltage needle 3 with
The pressure-wire of needle bed connects.The peripheral side of voltage needle 3 is cased with bottom gum cover 4, intermediate gum cover 6 and top gum cover 5, passes through these three
Gum cover makes voltage needle 3 not reach electric current needle, prevents voltage needle 3 and electric current needle from forming short circuit (it is of course also possible to by electricity
The modes such as mopping insulate on the peripheral side of pressing 3 to realize).Wherein, the inner wall in circular hole channel is equipped with the first ladder 15, intermediate
Ladder is withstood at the top of gum cover 6, and the bottom peripheral side of voltage needle 3 is equipped with the second ladder 16, and the bottom of bottom gum cover 4 is pressed in second
On ladder 16.The peripheral side of voltage needle 3 is cased with retraction spring 7, retraction spring 7 be sandwiched in bottom gum cover 4 and intermediate gum cover 6 it
Between, so that voltage needle 3 can bounce back in pressing, can be resetted after pressing.Gum cover 5 one end in top is protruded into channel, and the other end is visited
Out outside circular hole channel, the top peripheral side of voltage needle 3 is fixed with snap ring 11, and snap ring 11 is located at the top of top gum cover 5 and blocks
Top gum cover 5 prevents voltage needle 3 from dropping out circular hole channel from below.
The bottom surface of electric current syringe needle 1 and voltage needle 3 all carves out the sawtooth of dense distribution.In use, passing through sleeve 8 for probe
It is installed on needle bed, sees Fig. 3, when needle bed drives probe pressing, probe touches battery electrode column, and battery electrode column, which squeezes probe, to be made
Electric current shank 2 is retreated therewith and is more stretched out from the top of sleeve 8, and two filled on sleeve 8 pin B is along on electric current shank 2
Guide groove A it is mobile, during pin B is mobile in the tilting section of guide groove A, cannot live since pin B is fixed on sleeve 8
It is dynamic, it forces electric current needle to have transverse rotation movement during pressing battery electrode column, drives voltage needle 3 together when electric current needle rotates
Rotation, sharp sawtooth of 3 bottom surface of electric current syringe needle 1 and voltage needle slightly scratches the separation layer of battery electrode column during this, reaches
The purpose that electric current syringe needle 1, voltage needle 3 are effectively contacted with battery electrode column.After pin B leaves the tilting section of guide groove A, into guide groove A
Lower vertical section, move electric current shank 2 along own axes in the track restriction effect of lower vertical section.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the invention, rather than to this hair
It is bright create protection scope limitation, although being explained in detail referring to preferred embodiment to the invention, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the invention, without departing from this
The spirit and scope of innovation and creation technical solution.
