Description

A kind of anchor clamps that are used for printed circuit board (PCB)

Technical field

The present invention relates to a kind of anchor clamps, specifically a kind of simple and easy anchor clamps that are used for printed circuit board (PCB).

Background technology

Make processing factory and often see no anchor clamps bulk deposition, promptly occupations of land side is not attractive in appearance again, how to prolong the life-span of anchor clamps or how to improve the multipurpose of anchor clamps, be part solve pile up, a direction of saving input, energy-saving low-carbon.

Hardware debug assistant (HAH) can be used as simple and easy anchor clamps and uses, but comes with some shortcomings.As: 1. for 2mm, 2.54mm etc. single/arrange the bad down pin of interface more.2. because the PCBA of the corresponding single face measuring point of HAH machinery can't draw back side measuring point signal.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structurely, be convenient to the down anchor clamps that are used for printed circuit board (PCB) of pin.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:

A kind of anchor clamps (PFA) that are used for printed circuit board (PCB) comprise hardware debug assistant (HAH), based on hardware debug assistant (HAH), increase by two mechanisms, Phalanx syringe and bottom surface auxiliary needle battle array; The Phalanx syringe cylinder structure, for example 4*16 probe syringe is combined in a cube with constant spacing, and apart from two kinds of syringe arrangement modes are arranged, a kind of is usually row's needle mould formula at each, and corresponding Dan Shuan Pai is many. row's interface; A kind of is interleaving mode, corresponding 15.Insert probe according to actual conditions, draw the signal measurement of 2*10 port like need, can insert 2*10 probe, the cube top and bottom are fluted, can embed between specific clamping plate, the rectangle frame, and the Phalanx syringe is provided with the external interface of X*Y; Rectangle frame is provided with the nut of screwing, can cube is closely fixing, and plug and rectangle frame are an integral body, can insert probe holder and fix.The 4*16 holding wire boundling that connects can be fixed on the probe mechanical arm through band; Bottom surface auxiliary needle battle array: constitute by main mechanical arm, probe mechanical arm, pedestal, probe holder; Main mechanical arm and probe mechanical arm can be realized positioning of rotating in the plane; Probe holder can be inserted the signal of different probe structure realization PCBA and draw; Integral body is riveted on pedestal, and the time spent can not regain in pedestal in mechanism.

The Phalanx syringe: corresponding different spacing (2.54mm/2mm/..) stitch has X*Y (maximum 4*16) array syringe corresponding.

Rectangle frame length is slightly larger than cubical length, and the rectangle frame both sides have guide rail restriction clamping plate to slide at guide rail.

Main mechanical arm: can rotate at horizontal plane, can pass through screw means, be fixed in the demand position.

The probe mechanical arm: can rotate at horizontal plane, an end and the riveted joint of main mechanical arm, the other end connects probe holder for the cover head mechanism.

Pedestal: main mechanical arm is riveted on pedestal, and there is the corresponding signal output interface pedestal front portion.

Probe holder: can insert various probe, pressure bar, Phalanx syringe.

Beneficial effect of the present invention is:

The simple and easy anchor clamps of multipurpose of the present invention take up an area of little, and the time spent is not recoverable; Corresponding different PCBA draws through traveling probe position realization various signals; The anchor clamps lead-in wire overlaps the recycling that can realize anchor clamps with relevant test instrumentation or feature board.

Embodiment

Said anchor clamps have additional Phalanx syringe and bottom surface auxiliary needle battle array.

Fig. 1 is the Phalanx syringe cylinder structure, is made up of three parts, and for example 4*16 probe syringe is combined in a cube 101 with constant spacing, and apart from two kinds of syringe arrangement modes are arranged, a kind of be the needle mould formula of arranging usually at each, corresponding single double arrange interface more; A kind of is interleaving mode, corresponding 15.Can insert probe according to actual conditions; Draw the signal measurement of 2*10 port like need, can only insert 2*10 probe, cube top and bottom fluted 104; Can embed between clamping plate 201, the rectangle frame 202; 4*16 holding wire boundling 102 can be fixed on the probe mechanical arm 303 through band, and the Phalanx syringe is connected with the external interface 103 of 4*16.

Rectangle frame 202 length are slightly larger than the length of cube 101, and rectangle frame 202 both sides have guide rail restriction clamping plate 201 to slide at guide rail.

Rectangle frame 202 is provided with the nut 203 of screwing, can cube 101 is closely fixing, and plug 204 is an integral body with rectangle frame 202, can insert probe holder and fix.

Bottom surface auxiliary needle battle array:

Main mechanical arm 401 can rotate at horizontal plane, can fix through the screw of screwing, and on main mechanical arm 401, be provided with snap close 405, can lock together with another arm.

Probe mechanical arm 402 is connected to shielded signal wire 408, and the flex point place is provided with knob 407, can rotate at horizontal plane, and tail end connects cover head mechanism 301 (404), inserts probe holder 302.

Pedestal 403, the corresponding signal output interface.Pedestal 403 is connected through knob 406 with main mechanical arm 401; Guide rail is arranged on the pedestal, and alignment pin 409 can move the back in guide rail fixing.

Alignment pin 409; The head of screw is placed in the slide rail removable, and long spiro nail 412 upper ends do not have screw thread, and there is screw thread the lower end; Nut 411 can be screwed and make long spiro nail 412 fixing on slide rail; ESD packing ring and spring structure 410 are fixed on the nut 411, and when alignment pin 409 location and after through nut 411 lockings, the location hole of PCBA can insert.

Probe holder 302 can insert various probe, pressure bar, Phalanx syringe.

Anchor clamps constitute signal: PCBA side location hole inserts the alignment pin of the pedestal of HAH (602) and PFA (605); Pull out the L parts of HAH and the probe mechanical arm of PFA; Termination sleeve part separately inserts a wire 603; The locking respective screws makes HAH and the PFA can relative motion, and the assurance anchor clamps are to the location of PCBA; Launch mechanical arm separately; Change corresponding probe 601 (comprising Phalanx syringe, pressure bar etc.); The test mechanical arm is locked all screws after navigating to corresponding measuring point; Draw line 606 from separately pedestal and Phalanx syringe, insert outside instrument or include the casing 607 of feature board, handle 604 is realized the manual test of anchor clamps.

Have more signal to draw the PCBA of (can't cover or stress had relatively high expectations with the Phalanx syringe) to some positioning accuracy requests are high with port end face, can add and generally do evil through another person 608 and base plate 609, base plate is the plane; There is certain frictional force on the surface; Base plate has four grooves 610, and HAH and PFA can move in vertical slot and be fixing, does evil through another person and can move and fixing at translot; With the different big or small PCBA of correspondence, HAH and PFA need not a series of actions of additional fastening 603 under this kind mode.

More than the disclosed specific embodiment that is merely this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, the distortion of making should be regarded as belonging to protection range of the present invention.
