Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and specific embodiment, to the utility model
It is described further.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Further to illustrate that the utility model is the technical means and efficacy for reaching predetermined purpose and being taken, below in conjunction with
Specific embodiment of the present utility model is described in detail in attached drawing and preferred embodiment.
Fig. 1 is please referred to, the utility model embodiment provides a kind of flying needle mould group for high speed flying probe tester, including one
Needle folder 1 and be vertically installed in needle folder 1 free end on a syringe needle 2, wherein the needle folder 1 include a rectangular resilient bezel 11 and
The fixed strip 12 being connected in the fixing end 111 of rectangular resilient bezel 11, the syringe needle 2 are vertically installed in oneself of rectangular resilient bezel 11
By on end 112.
When syringe needle 2 is close to the test point of board pads to be tested, since the fixing end 111 of rectangular resilient bezel 11 is solid
Due in needle holder, and free end 112 generates elastic deformation because pushing ahead.Specifically, rectangular 11 free end 112 of resilient bezel
Two right angles generate deformation simultaneously, because of the inhibition of the lateral right-angle side by fixing end 111 at front side edge right angle, cause
The deformation of front side edge right angle and angle becomes smaller, because of the inhibition of the lateral right-angle side by fixing end 111 at back side edge right angle, cause
The deformation of back side edge right angle and angle becomes larger.The deformation generated by two right angles of rectangular 11 free end 112 of resilient bezel, causes certainly
Bending is not generated by the end movement routine at end 112, so that syringe needle 2 be made to be able to maintain the straight line path perpendicular to pad originally always
It moves forward, i.e., the test point on the vertical contact pad of 2 energy straight line of syringe needle, the progress path of syringe needle 2 are always maintained at straight line and hang down
Directly, without arc-shaped bend；Similarly, when syringe needle 2 reversely removes test point, the free end 112 of rectangular resilient bezel 11 is anti-
To reset and reverse strain, it is able to maintain syringe needle 2 always and was reversely retreated perpendicular to the straight line path of pad originally.
In the present embodiment, one first arc groove is respectively formed on four insides right angle of the rectangular resilient bezel 11
113, it is preferred that first arc groove 113 is semicircular arc.By the design of the first arc groove of right angle 113, it is thinned right angle
Thickness, conducive to rectangular 11 free end 112 of resilient bezel two right angles generate deformation.
Meanwhile in order to further increase the freedom degree that two right angles of rectangular 11 free end 112 of resilient bezel generate deformation,
It is respectively formed on the two opposite outer face of rectangular 11 free end 112 of resilient bezel corresponding with the first arc groove 113
One first side groove 114.
In the present embodiment, the fixed strip 12 is prolonged from 111 inner side edge of fixing end of rectangular resilient bezel 11 to free end 112
It stretches, and the length of the fixed strip 12 is less than the length of rectangular resilient bezel 11, width is less than the width of rectangular resilient bezel 11, makes at this
A U-shaped elastic deformation space 115 is formed in rectangular resilient bezel 11 and positioned at 12 periphery of fixed strip.It is free in rectangular resilient bezel 11
While end 112 generates deformation, the two sides of rectangular resilient bezel 11 are driven to swing in 12 two sides of fixed strip, in the process of swing
In, 115 shape of U-shaped elastic deformation space generates adaptive change.
In rectangular 11 free end of resilient bezel, 112 edge integrally formed with a connection piece 116, which is set to
116 free end of connector.Specifically, 116 anterolateral surface of connector and rectangular 11 anterolateral surface of resilient bezel are in always
On line, which is vertically installed in 116 free end of connector.In the present embodiment, the connector 116 is an elastic component
116', and a square hole 1161 is offered in elastic component 116'.
Meanwhile it being respectively formed with one second arc groove 1162 on four insides right angle of the square hole 1161, preferably
, second arc groove 1162 is semicircular arc.By the design of the second arc groove of right angle 1162, it is thinned the thickness of right angle
Degree is conducive to elastic component 116' right angle and generates deformation.
Meanwhile in order to further increase the freedom degree that elastic component 116' right angle generates deformation, in the elastic component 116'
Lateral surface on be formed with several second side grooves 1163 corresponding with the second arc groove 1162.
In order to which more easily fixed strip 12 is fixed in needle holder, if the present embodiment offers on the fixed strip 12
Dry fixation hole 121, as long as fixed strip 12 can be fixed in needle holder by fixed screw.
In the present embodiment, the rectangular resilient bezel 11 is square structure, and can be square may be rectangle, excellent
Choosing, which is rectangle.
When specifically used, the present embodiment flying needle mould group is fixed in needle holder by fixed strip 12, in high speed
When flying probe tester is run, after position coordinates of the flying needle mould group in X-axis and Y-axis all regulate, it will be flown by Z axis regulating mechanism
Needle mould group is promoted to board pads direction to be tested, when the syringe needle 2 of flying needle mould group is close to pad test point, due to rectangular
The fixing end 111 of resilient bezel 11 is fixed in needle holder, and free end 112 generates elastic deformation because pushing ahead, to protect
Test point on the vertical contact pad of the 2 energy straight line of syringe needle of card flying needle mould group, the i.e. progress path of syringe needle 2 are always maintained at straight line
Vertically, without arc-shaped bend, it is conducive to improve measuring accuracy.Correspondingly, also there is phase in another side in board pads
Same flying needle mould group does identical movement, is combined by the flying needle mould group of board pads two sides, vertical simultaneously in pad two sides
The same test point on contact pad；Then, syringe needle 2 removes the test point, while the free end 112 of rectangular resilient bezel 11 is multiple
Position, and can reversely generate elastic deformation, to guarantee that syringe needle 2 can the vertical removal test point of straight line, i.e. the removal road of syringe needle 2
It is vertical that diameter is always maintained at straight line, without arc, is conducive to improve measuring accuracy, the test of the test point can be completed.It adopts
With flying needle mould group provided in this embodiment, traditional pen meter of universal meter can be replaced, by the movement of flying needle mould group, is contacted on circuit board
Each network measuring point, whether the route come in measuring circuit plate be connected or with the presence or absence of line short phenomenon.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore technical characteristic identical or approximate with the utility model above-described embodiment is used, and obtained other structures,
It is within the protection scope of the utility model.
