Description

Minisize signal measuring probe

The utility model relates to each quasi-instrument of measuring electric variable or the general structure parts of device, further is meant a kind of miniature acquisition of signal head that belongs to measuring probe.

At present, high-speed and high target are pursued in the development in fields such as electronic technology, control automatically, communication, computing machine invariably, and electronic measuring instrument is also being pursued high precision, yet but ignores to some extent on the structure of exploring block.As the exploring blocks commonly used such as crocodile clip that use in the test pencil of universal electric meter, oscillographic probe, the laboratory, still keep traditional planform unalterable, be difficult to adapt to the electronic devices and components trend microminiaturization of electronic equipment, the measurement needs of integrated development, use and feel inconvenience deeply.In measuring process, survey crew always feels that both hands are not enough, and needs two people that have to sometimes could operate above the cooperation.And people's eye, hand and usefulness, should look after and measure partly, observe instrument range and range of adjustment again, often attend to one thing and lose sight of another, usually improperly make exploring block slide and cause short circuit because hold unconsciously, so that the accident that burns out electronic devices and components and circuit happens occasionally, and causes unnecessary loss to work.The electric test chuck of several patent applied fors is arranged, though have more safe and reliable test performance, its detecting head top is a crotch shape, is difficult to adapt to the needs under various measurement occasions, and structure is comparatively complicated, and operation does not still want to take the trouble.

The purpose of this utility model is to provide a kind of need one people just can carry out measuring operation and miniature acquisition of signal head safe and reliable, simple and light, that can be widely used in various measurement occasions easily.

Solution of the present utility model is as follows.It has a metal measurement folder that forwards is bent into two intermediate plates separately from afterbody; metal is measured folder and is all wrapped up by an elastic insulated shell except that the head of two intermediate plates is exposed; and the material of elastic insulated shell puts in metal also integratedly and measures the afterbody that presss from both sides between two intermediate plates; the afterbody of elastic insulated shell has the lead perforation; a connection lead passes this lead perforation and is electrically connected with metal measurement folder from the outside; expose that the head of measuring two intermediate plates of folder at the metal in elastic insulated shell the place ahead is conical and one is long and the other is short fits; head at these two intermediate plates respectively has a half-cylindrical laterally holding tank and a half-cylindrical vertical holding tank in correspondence with each other in correspondence with each other; these two horizontal holding tanks are combined into a horizontal clamping hole; these two vertical holding tanks are combined into a vertical clamping hole, and the head noncontact that metal is measured two intermediate plates of folder partly scribbles the organic insulation protective finish.

The utility model with said structure will connect the lead tail end and connect by connector and electronic measuring instrument when concrete the use, just can measure.Measurement to endoporus needs only the inside of the conical nose of probe being inserted detection place.The measurement at outer surface and flat sides place, then the place, slit inserts from the head, and intermediate plate can open automatically, and tested part is clipped in vertical clamping hole or horizontal clamping hole position, detecting head can be fixed up, and hand just can leave.The taking-up detecting head only need be extracted it and get final product.Because the dual elastic reaction of intermediate plate and elastic insulated shell, detecting head can return to the original form rapidly, and keeps certain dynamics.Like this, to various components and parts,, all can measure as integrated circuit, transistor, resistance, electric capacity, plug, socket, binding post and lead etc.

The utility model is small and exquisite flexibly, and is easy and simple to handle, safe and reliable, can be widely used in various measurement environment.It has accomplished the pin of the various components and parts of installing on printed circuit board (PCB) is surveyed easily, no matter how its shape can both adapt to.And,, can not cause short circuit even under the situation that comes off or slide because insulation processing has been carried out at the noncontact position of detecting head yet.Owing to be the face contact mostly when measuring, contact resistance is little, so be particularly suitable for the measurement of the little electric current of low pressure, can be used as the instrument that school, R﹠D institution etc. use with instrument, instrument, household electrical appliance manufacturer and relevant maintenance service entity and individual in experiments such as physics, communication, automatic control, computing machine.If the afterbody of this detecting head is done suitably to improve, then can satisfy the connection request of particular component (as the oscilloscope signal decay), also can be contained in electronic logic nib portion as novel product, the accessory that also can be used as instruments such as various multimeters, registering instrument, carrier amplifier offers the user.It is simple in structure, and low production cost is easy to penetration and promotion.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 2 and Fig. 3 are respectively A-A cut-open view and the B-B cut-open view of Fig. 1;

Fig. 4 to Fig. 9 is respectively the synoptic diagram of the utility model detecting head when measuring integrated circuit, transistor, plug, socket, lead and binding post.

Reference numeral among Fig. 1 to Fig. 3 is: 1, and metal is measured folder; 2, elastic insulated shell; 3, connect lead; 4, the lead perforation; 5, horizontal holding tank; 6, vertical holding tank.

Referring to Fig. 1, it is the direct impact briquetting of material that metal measurement folder (1) can adopt the big brass wire of elastic strength, or formalizes through pincers worker bending, boring, grinding in trial-production, does thermal treatment and surface treatment then.Head noncontact part can not be come off by the organic insulation coating protection, and coating thickness is less than 0.05mm.As the exact instrument parts, measure folder (1) and require to have better flexible metal material to make, after the thermal treatment setting, the gold-plated enhancing conductive effect of still needing.Connecting lead (3) can adopt 0.5mm multiply soft copper lead or coaxial wire by difference requirement and the welding of measurement folder afterbody.Elastic insulated shell (2) adopts resilient insulating material, as rubber, plastics etc., presses relevant processes, and pours into a mould typing after connection lead and the welding well of metal measurement folder.
