Description
Technical field
This utility model relates to a kind of probe test auxiliary device, particularly relates to a kind of floating contact pin measuring head.
Background technology
Due to the difference of product to be measured, pin typically will make floating, if but product needed is horizontally inserted test,
Traditional ralocatable mode is easy to the most just lead, thus test crash or damage probe.
Existing floating measuring head is the mode adding spring with traditional pin screw, the surplus of floating by pin screw and
The gap of pin screw hole ensures, being used in required precision the highest, the occasion being inserted vertically into test is more convenient, if but used
In the occasion that required precision is high, or being inserted in parallel into the occasion tested, repeat guiding accuracy relatively low, the probability of test crash is very
High.
Summary of the invention
This utility model overcomes the deficiencies in the prior art, solves above-mentioned deficiency, adds bullet with the air supported head of wedge structure
The mode of spring, it is ensured that repeat guiding accuracy, thus ensure that the rate of being successfully tested.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of floating contact pin measuring head, including: band
There are the floating seat of wedge-shaped slot, the air supported head of a wedge structure being arranged in wedge-shaped slot, it is characterised in that described air supported head is big
First end heads in floating seat towards described wedge-shaped slot, and one end of a spring is against bottom wedge-shaped slot, and the other end props up described floating
Dynamic head major part one end, described air supported head free end connects has probe test head, described floating seat to connect cylinder by fixed plate.
In one preferred embodiment of this utility model, described cylinder promotes the direction of motion of floating seat and the axle of described spring
Consistent to direction.
In one preferred embodiment of this utility model, it is solid that described probe test head is disposed with probe fairlead, probe
Reservation and probe wire outlet seat, described probe wire outlet seat connects described air supported head.
In one preferred embodiment of this utility model, described probe fairlead is provided with probe aperture.
In one preferred embodiment of this utility model, described probe fairlead is set in described probe base.
In one preferred embodiment of this utility model, described probe base, described probe wire outlet seat and described air supported head
Between all connected by alignment pin and screw.
This utility model solves defect present in background technology, and the air supported head of this utility model wedge shape adds spring
Design so that every time return to same position, it is ensured that repeat guiding accuracy.Employing split designs, and can prevent probe length not
The situation of one, and looper is had mistake proofing effect.
Certainly the air supported head structure of this utility model wedge-shaped slot and wedge shape can change the air supported head of conical grooves and conical structure into,
Identical function can be realized.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the three-dimensional structure diagram of preferred embodiment of the present utility model；
In figure: 1, probe fairlead, 2, probe base, 3, probe wire outlet seat, 4, air supported head, 5, floating seat, 6, spring,
7, fixed plate, 8, cylinder.
Detailed description of the invention
Being described in further detail this utility model presently in connection with drawings and Examples, these accompanying drawings are simplification
Schematic diagram, illustrates basic structure of the present utility model the most in a schematic way, and therefore it only shows the structure relevant with this utility model
Become.
As it is shown in figure 1, a kind of floating contact pin measuring head, including: with the floating seat 5 of wedge-shaped slot, one is arranged on wedge shape
The air supported head 4 of the wedge structure in groove, air supported head 4 major part one end heads in floating seat 5 towards wedge-shaped slot, one end of a spring 6
Being against bottom wedge-shaped slot, the other end props up air supported head 4 major part one end, and air supported head 4 free end connects probe test head, floating seat
5 connect cylinder 8 by fixed plate 7.
Cylinder 8 promotes the direction of motion of floating seat 5 consistent with the axial direction of spring 6.
Probe test head is disposed with probe fairlead 1, probe base 2 and probe wire outlet seat 3, probe wire outlet seat 3
Connect air supported head 4.It is provided with probe aperture on probe fairlead 1.Probe fairlead 1 is set in probe base 2.
All connected by alignment pin and screw between probe base 2, probe wire outlet seat 3 and air supported head 4.
Probe fairlead 1 play the guiding role, and can make to test in the product of insertion accurately that probe is vertical, and probe is contained in spy
Pin is fixed in seat 2, and probe wire outlet seat 3 has wire hole, and the line of probe can from hole out, and floating seat 5 can be made by spring 6
Air supported head 4 remains vertical, because floating seat 5 and air supported head 4 have the inclined-plane cooperated, when probe inserts product, floating
Can all around float for dynamic 4 makes probe be connected to product the most accurately, and mechanism is promoted by cylinder 8.
Test probe: being a kind of test connecting electronic component being applied in Electronic Testing test PCBA, surface uses plating
Gold is conducive to conducting electricity enhancing, the most all selects SK4 material, and there is the high-performance spring 8 of average life 30,000 ~ 1,000,000 times inside.
This product is floating contact pin measuring head, for fixing test probe, and makes test probe precisely contact by cylinder
Chaining pin is treated accordingly to product.
Above according to desirable embodiment of the present utility model for enlightening, by above-mentioned description, related personnel is complete
Various change and amendment can be carried out in the range of without departing from this utility model technological thought.This utility model
The content that is not limited in description of technical scope, it is necessary to determine technical scope according to right.
