Abstract
The utility model provides a watch pen chunk, comprising a main body and a tower cap, wherein the main body is a cylinder; the front part of the main body is provided with threads matched with the tower cap; the front end of the main body is provided with a cone body matched with an inner cone of the tower cap; the cone body is divided into 2-8 sections so as to increase elastic compression amount; the rear part of the main body is provided with an element matched with a watch rod; and the rear end of the main body is provided with a through groove and/or an axial hole. The utility model also provides a watch pen with the chunk, which consists of a pen rod and the chunk; the chunk comprises the main body and the tower cap; the main body is a cylinder; the front part of the main body is provided with threads matched with the tower cap; the front end of the main body is provided with the cone body matched with the inner cone of the tower cap; the cone body is divided into 2-8 sections; the rear part of the main body is provided with an element matched with the watch rod; and the rear end of the main body is provided with the through groove and/or the axial hole. The watch pen chunk and the watch pen with the chunk have the advantages that: replacement of a probe is convenient, remoulding of a traditional universal meter and a traditional oscilloscope are applicable, the tip of the probe can be inwards inserted into the watch pen chunk to keep, so that the tip of the probe is prevented from injuring a person or being fractured.
Description
Technical field
The utility model relates to the test pencil of multimeter, oscillograph etc.
Background technology
Traditional multimeter, the oscillographic tip of the brushstyle of a writing or painting of test pencil is comparatively thick, only be applicable to measure 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.Develop rapidly along with electronics industry, it is tiny that various large scale integrated circuits are used more and more (as computer main board, mobile phone B GA chip, pad, camera etc.) pins, as adopt the test pencil of traditional multimeter to measure, and its measuring accuracy is difficult to guarantee, simply can't implementing of having measured.Cause the pin short circuit during measuring voltage that What is more easily, integrated circuit (IC) chip is damaged and is scrapped, and causes unnecessary economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of test pencil chuck, so that be replaced with the tip of the brushstyle of a writing or painting (probe) of required thickness, length.
The utility model provides a kind of test pencil chuck, it is characterized in that: comprise main body and tower cap, main body is a cylinder, and body front part has screw thread to match with the tower cap, body front end is that cone matches with the female cone of tower cap, cone is divided into 2～8 lobes, and to increase the elastic compression amount, back body has the element that matches with the table bar, body rear is shaped on hole and/or groove, be used for lead-in conductor, or, implement probe and be electrically connected with test pencil through main body, tower cap.
During assembling, the test pencil clamper main body is spun on multimeter, the oscillographic table bar, and the test pencil clamper main body is electrically connected with multimeter, oscillograph, the tip of the brushstyle of a writing or painting (probe) is inserted in the main body of test pencil chuck with lead, screw on the tower cap of test pencil chuck, clamp the tip of the brushstyle of a writing or painting (probe) and get final product.
The test pencil chuck that the utility model provides, the extexine of its main body and/or tower cap is an insulator, in order to avoid bring human-induced signal, static into chip, circuit, instrument when measuring, causes chip to damage, in order to avoid when measuring high pressure, human electric shock's accident takes place.
The test pencil chuck that the utility model provides, its back body is screw thread, socket pin etc. with the element that the table bar matches.
The test pencil chuck that the utility model provides, its body rear has female cone, so that the guiding tip of the brushstyle of a writing or painting (probe) inserts or welding lead.
The utility model also provides a kind of test pencil of Tourniquet clamping head, it is made up of penholder and chuck, chuck comprises main body and tower cap, main body is a cylinder, body front part has screw thread to match with the tower cap, and body front end is that cone matches with the female cone of tower cap, and cone is divided into 2～8 lobes, back body has the element that matches with penholder, and body rear is shaped on groove and/or axial hole.
The utility model also provides a kind of test pencil of Tourniquet clamping head, and its penholder has internal taper hole, so that match with oscillographic test pencil profile.
The test pencil chuck that the utility model provides, its advantage is: be convenient to change probe; Be applicable to and transform traditional multimeter, oscillograph voluntarily; Probe tip can be inserted inwards test pencil chuck ground and preserve, in order to avoid probe tip is hurted sb.'s feelings or fractureed.
