Abstract

The utility model relates to a convenient and safe multimeter test pencil, which is applied to the field of electronic maintenance. The utility model is composed of two probes which can be used rotatively, wherein, one probe can be matched with a grapnel and a spring mechanism to clamp an element pin connected with a test point, and an insulating sleeve and a positioning pin are arranged on the other probe to cause the probe to be conveniently clamped onto a tube pin of an integrated package or other element pins without slipping. Thus, the short circuit is caused in the way that the probes are contacted with two contiguous element pins. The utility model is convenient and safe in use.

Description

Convenient and safe multimeter test pen

The utility model is a kind of improved multimeter test pen.

At present, widely used multimeter test pen is made up of plastic penholder and metal probe.Owing to do not have locating device and insulation sleeve on the probe, in use because of contemporary electronic equipment part arrange very tight, so when measuring especially to the integrated package pin, accidentally test pen will landing on measurement point, touches adjacent two elements, causes short circuit.Very easily burn out element, fault coverage is enlarged.Cause unnecessary loss.Also because probe does not have the hook clamp device, hand can not leave test pen during measurement.By literature search finds no the improved multimeter test pen of the utility model feature to the G01R class.

The purpose of this utility model just provides a kind of convenient and safe multimeter test pen.

The purpose of this utility model is to realize like this.The first and second two kinds of probes that can use are by turns arranged on a test pen.Half of first probe front end transversal section made and visited point, and second half makes groove to recurve at the root of putting point on the skin.This structure, the grapple that can be engaged on the probe on the plastic jacket is movably clamped the component pin that links to each other with test point.Insulation sleeve on the second probe sheath only exposes and visits point.There is the register pin with the insulation sleeve one on spy point side, and the first probe of positive and negative test pen is the same.The second probe is slightly different, Yi Bian one is the spy point register pin is arranged that this suitable integrated package lead pin pitch is in the situation more than 0.7 millimeter.Another visits sharp both sides all register pin.The situation of this suitable integrated package lead pin pitch 0.3 millimeter.

First probe of the present utility model can be clamped the component pin that links to each other with test point.Hand can leave test pen, comes the feature button on the operating electronic equipment, observes the numerical value change situation of corresponding measurement point.The second probe can block to come on the component pin easily to be measured.Not landing, not short circuit.Cause unnecessary loss with unburned loop member.The multimeter test pen did not possess above-mentioned functions in the past, used both inconvenient, dangerous yet.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the organigram of the convenient and safe multimeter test pen that the utility model proposes.Fig. 2, Fig. 3 are the amplification organigrams of two kinds of second probes.Wherein (14) are probe, and (15) are insulation sleeve, and (16) are register pins, and Fig. 4 is a first probe enlarged diagram.Fig. 5, Fig. 6 are the situation synoptic diagram of second probe card when coming to the integrated package pin.Fig. 7 is the first kind probe synoptic diagram when clamping component pin.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This test pen comprises movable penholder (1), first probe (3) and second probe (7) is arranged on the movable penholder (1) and go up with main pen arm (2) that mother metal sieve (8) links to each other and the first and second metal rib-loops (6) of popping one's head in one, on probe, have movably to be fixed with and grab the plastic jacket first (4) of colluding (5), plastic jacket first (4) with on main pen arm (2) movably plastic jacket second (9) link to each other by hinge (10).Between main pen arm (2) and the plastic jacket second (9) spring (11) is arranged, (12) are plug wire, and lead-in wire (13) links to each other with mother metal sieve (8).

Spur plastic jacket first (4) forward, plastic jacket first (4) links to each other with plastic jacket second (9) with crossing hinge (10), be subjected to the effect of spring (11), collude (5) and catch on component pin and come to first and visit on the other groove of point, can clamp component pin and measure with being fixed on grabbing on the plastic jacket first (4).

Spur plastic jacket (4) forward, get out of the way to one side, can screw off movable penholder (1), the transposing direction screws on again, can use probe second.
