Abstract

The invention discloses a PCB small probe test fixture which comprises a base. The PCB small probe test fixture is characterized by further comprising a lower probe board, a containing board, probe blocks and a guide pillars. The lower probe board is arranged on the top of the upper surface of the base, the four corners of the base are respectively provided with one corresponding guide pillar, the containing board which is capable of moving up and down along the guide pillars and is used for containing a PCB is arranged on the guide pillars, the lower probe board is provided with a plurality of the locating openings, the probe blocks are detachably mounted in the locating openings, each probe block is provided with a plurality of probes, the lower probe board is provided with a plurality of springs placed below the containing board, and the containing board is provided with probe holes allowing the probes to penetrate through. The PCB small probe test fixture solves the problems that for a PCB test fixture, due to the fast that a probe board needs to be replaced after probes are damaged, cost is greatly increased, the design of the probe board is relatively fixed, university is poor, and the application range is small. The PCB small probe test fixture is simple in structure, convenient to use, good in university, convenient to replace and capable of lowering use cost.

Description

The little pin measurement jig of a kind of pcb board

Technical field

The present invention relates to a kind of measurement jig, particularly relate to the little pin measurement jig of a kind of pcb board.

Background technology

PCB(PrintedCircuitBoard), Chinese is printed circuit board, claims again printed circuit board (PCB), printed-wiring board (PWB), is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.Current pcb board measurement jig, how patchhole is directly set on needle plate, being convenient to probe directly stretches into patchhole and carries out follow-up detection, if but probe has damage, just must exit patchhole, like this due to the structure of probe, after exiting, can make patchhole diameter become large, again insert after probe, because aperture becomes large, pcb board is after being again pressed onto above probe, probe can tilt, cause like this probe there is no engaged test point, cause testing or measuring accuracy declines greatly, affect the use of equipment, the needle plate that must again more renew, greatly improve cost, design to patchhole on simultaneously current needle plate and the length of probe that patchhole is inserted have all been wanted detail requirement, each needle plate can only use for the detection of a product, versatility is poor, the scope of application is less.

Summary of the invention

In order to solve pcb board measurement jig in prior art, probe need to be changed needle plate after damaging, and causes cost greatly to improve, and needle plate design is comparatively fixing, versatility is poor, and the problem that the scope of application is less the invention provides a kind of simple in structure, easy to use, versatility is good, is convenient for changing, and reduces the little pin measurement jig of pcb board of use cost.

In order to address the above problem, the technical solution used in the present invention is:

The little pin measurement jig of a kind of pcb board, comprise base, it is characterized in that: also comprise lower needle plate, place plate, probe block and guidepost, be provided with lower needle plate at base upper surface top, on four angles of base, be respectively arranged with a guidepost, on guidepost, be provided with can move up and down along guidepost for placing the placement plate of pcb board, on lower needle plate, be provided with some positioning ports, described probe block is dismountable to be arranged in positioning port, on probe block, be provided with some probes, on lower needle plate, be provided with some springs of placing below plate that are positioned at, on placement plate, be provided with the probe aperture of passing for probe.

The little pin measurement jig of aforesaid a kind of pcb board, is characterized in that: also comprise top board and pressure bar, above placement plate, be provided with top board, be connected with the pressure bar that makes to place plate level for pushing down placement plate upper surface in the bottom of top board.

The little pin measurement jig of aforesaid a kind of pcb board, is characterized in that: the reference column that is provided with some insertion pcb board pilot holes on the upper surface of lower needle plate.

The little pin measurement jig of aforesaid a kind of pcb board, is characterized in that: on lower needle plate, be provided with four row's probe blocks, the spacing distance between described every row's probe block equates.

The little pin measurement jig of aforesaid a kind of pcb board, is characterized in that: be provided with square limited block in placement plate two bottom sides.

The little pin measurement jig of aforesaid a kind of pcb board, is characterized in that: described lower needle plate is positioned at the space that four guideposts surround.

The invention has the beneficial effects as follows: the little pin measurement jig of pcb board of the present invention, on lower needle plate, be provided with some positioning ports, described probe block is dismountable to be arranged in positioning port, on probe block, be provided with some probes, while having like this probe to damage, directly change the probe block that damages probe place, greatly improved replacing speed, ensure the needs that subsequent detection is used, also reduced and detected the cost using.Owing to being provided with some positioning ports on lower needle plate, can place like this probe block of different probe arrangement on positioning port simultaneously, can be used for the detection of different pcb boards, usable range is wider, and versatility is better.

Brief description of the drawings

Fig. 1 is the little pin measurement jig of pcb board of the present invention structural representation.

Fig. 2 is needle plate structure schematic diagram under the present invention.

Embodiment

Below in conjunction with accompanying drawing, the present invention will be further described.

As shown in Figure 1-2, the little pin measurement jig of a kind of pcb board, comprise base 1, lower needle plate 2, place plate 3, probe block 4, guidepost 5, top board 7 and pressure bar 8, be provided with lower needle plate 2 at base 1 upper surface top, on 1 four angles of base, be respectively arranged with a guidepost 5, on guidepost 5, be provided with can move up and down along guidepost 5 for placing the placement plate 3 of pcb board, on lower needle plate 2, be provided with some positioning ports 6, described probe block 4 is dismountable to be arranged in positioning port 6, on probe block 4, be provided with some probes, on lower needle plate 2, be provided with some springs 9 of placing below plate 3 that are positioned at, on placement plate 3, be provided with the probe aperture 10 of passing for probe.

Above placement plate 3, be provided with top board 7, be connected with in the bottom of top board 7 for pushing down placement plate 3 upper surfaces and make to place the pressure bar 8 of plate 3 levels.On the upper surface of lower needle plate 2, be provided with the reference column 11 of some insertion pcb board pilot holes.When design, on lower needle plate 2, be provided with four row's probe blocks 4, the spacing distance between described every row's probe block 4 equates.Be provided with square limited block 12 placing plate 3 two bottom sides, square limited block 12 can be placed the stroke that plate move down for restriction, avoid placing plate 3 and exceed stroke and cause damage, and lower needle plate 2 can be arranged in the space that four guideposts 5 surround.
