Abstract

A novel meter pen of multimeter comprises two meter pens and is characterized in that penpoints of the two pens are aciform, and the meter pen also comprises another pen, the penpoint of which is of an alligator clip type. Compared with the prior meter pen of multimeter, the utility model has the following advantages: as the measuring penpoint of the utility model is aciform, the measuring pen does not slip form the testing point and causes short circuit in the measuring process like the prior measuring pen, thereby the utility model is safe and reliable in use. In addition, the aciform penpoint of the utility model can be directly inserted to the gap in accurate interleaving for measurement, which is very convenient, accurate and rapid, while the prior measuring pen can not be inserted for measurement.

Description

A kind of novel test pencil of multimeter

Technical field

The utility model is a kind of electrician's instrument, is a kind of novel test pencil of multimeter specifically.

Background technology

The test pencil of traditional multimeter is a two-piece suit, be that each multimeter has two the same test pencils, the tip of the brushstyle of a writing or painting of these two test pencils is thicker, it be suitable for measuring measuring point more greatly, the electric equipment products of relatively disperseing, the electric equipment products not high as early stage electron tube, transistor, discrete component and integrated level.But develop rapidly along with electronics industry, the integrated level of various electric equipment products is more and more higher, and the leading foot of integrated circuit is more and more, more and more closeer, as adopts the test pencil of traditional multimeter to measure, its measuring accuracy is difficult to guarantee, simply can't implementing of having measured.What is more is because the measurement tip of the brushstyle of a writing or painting is too thick, makes that the tip of the brushstyle of a writing or painting very easily causes the short circuit of circuit easily from the measurement point slippage when measuring, and integrated package or circuit are damaged, and causes unnecessary economic loss.

Summary of the invention

The purpose of this utility model provides a kind of novel test pencil of multimeter, and it can overcome existing shortcoming in the prior art, can make measurement accurate, and convenient to use.

The purpose of this utility model is achieved in that it comprises two test pencils, it is characterized in that these two pens adopt the prong formula tip of the brushstyle of a writing or painting, and it also comprises other one-pen simultaneously, and the tip of the brushstyle of a writing or painting of this pen is the crocodile clip formula.

Multitester probe of the present utility model is in the middle of reality is used, test pencil with the crocodile clip formula tip of the brushstyle of a writing or painting under regular situation is clipped in by " common " of maintenance electrical equipment, and use a prong formula test pencil can measure any circuit node or end points, then another prong formula test pencil can be inserted the common port (COM end) of multimeter when measuring accurate insert row, utilize this moment the tip of two prong formula test pencils directly to insert the measurement of carrying out " dynamically " or " static state " parameter in the accurate insert row slit as need.

The utility model and traditional multitester probe compare, has following advantage: because the measurement tip of the brushstyle of a writing or painting of the present utility model is the prong formula, when measuring, can not resemble and cause short circuit phenomenon from the test point slippage traditional measuring pen, so safe and reliable.The prong formula tip of the brushstyle of a writing or painting of the present utility model in addition can directly insert in the slit of accurate insert row and measure, and is very convenient, accurate, quick.And traditional measuring pen can't be inserted, and can't measure at all.

Description of drawings

The utility model is described in more detail below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is that the utility model tip of the brushstyle of a writing or painting is the synoptic diagram of the test pencil of prong formula.

Fig. 2 is that the utility model tip of the brushstyle of a writing or painting is the structural representation of the test pencil of prong formula.

Fig. 3 is that the utility model tip of the brushstyle of a writing or painting is the synoptic diagram of the test pencil of crocodile clip formula.

Embodiment

By Fig. 1 and Fig. 2 as seen, the tip of the brushstyle of a writing or painting is that the test pencil structure of prong formula is: the end at lead 1 is fixedly connected with plug 2, the other end at lead is welded with the tip of the brushstyle of a writing or painting 3, the tip of the brushstyle of a writing or painting 3 is the prong formula, and the diameter of prong is 0.15-0.40mm, is fine gold silver draw point, 6 kinds of specifications are arranged, on the prong formula tip of the brushstyle of a writing or painting 3 soldering copper bars 4, and be connected with lead, be with detachable shell 5 in the outside of port pin by the copper bar.When the prong damage maybe needs to change the prong diameter, can unload lower casing 5, change prong.The utility model comprises two prong formula test pencils.

Shown in Fig. 3 is another kind of test pencil in the utility model, and promptly the tip of the brushstyle of a writing or painting is the test pencil of crocodile clip formula.One end attachment plug 7 of lead 6, the fixedly connected crocodile clip 8 of the other end.The utility model comprises the test pencil of a crocodile clip formula.

Claims

1, a kind of novel test pencil of multimeter, it comprises two test pencils, and the tip of the brushstyle of a writing or painting that it is characterized in that these two pens is the prong formula, and it also comprises other one-pen simultaneously, and the tip of the brushstyle of a writing or painting of this pen is the crocodile clip formula.

2, according to the test pencil of the said multimeter of claim 1, the diameter that it is characterized in that prong is 0.15-0.40mm, is fine gold silver draw point.
