Description

Multicore formula test pencil

[technical field]

The utility model relates to a kind of electric circuit inspection equipment, relates in particular to a kind of accurately multicore formula test pencil of quick testing circuit.

[background technology]

Along with the high speed development of electronic technology, variously all be unable to do without circuit, thereby make circuit also become increasingly complex from the merit application technology.Maintenance circuit is detected and the debugging detecting instruments such as multimeter, oscillograph that use more.A survey inspection function singleness of detecting instruments such as original multimeter, oscillograph when metering circuit, uses very inconvenient; Particularly the live line measurement of the integrated pin of live line measurement and integrated circuit is more inconvenient, and existing single detection pen core can not adapt to modern requirement.

[utility model content]

In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of detection pen core with multiple structure to be installed in the one-pen bar, and by lead and detect table and connect, in penholder, select the respective detection pen core according to different testing circuits, can be fast, accurately, the multicore formula test pencil of testing circuit fault safely.

The technical method that its technical matters that solves the utility model adopts is: a kind of multicore formula test pencil, comprise a body, described body one end is provided with chute, this chute the inner is provided with screens, in a body port end cap is housed, in end cap, be provided with fairlead, described the body other end is equipped with nib by the taenidium retaining ring, be connected with a body inner chamber at nib guide plate is housed on the component level, on guide plate, be provided with guide hole, in this guide hole, be set with pen core, test rod is housed at pen core and pen tip place, the other end at pen core is enclosed within by handle in the body chute, on the pen core between handle and guide plate spring is housed.

Described body, nib and end cap are insulator.

Described pen core handgrip end is an insulator, is conductor at guide plate with detecting rod end.

Described test rod is needle-like test rod, shaft-like test rod, tubulose test rod or sheet detection bar.

The one side of described sheet detection bar is a conductor, and three is insulator in addition.

Described guide plate communicates with measuring instrument by lead.

The beneficial effects of the utility model are: needle-like, shaft-like, tubulose, sheet detection bar are installed in the body, connect with measuring instrument by lead, when testing circuit, can be according to the detected circuit actual conditions, as long as stir handle in the body groove gently, select respective detection bar in the pen, just can be easily, fast, accurately, test circuit safely.Have characteristics rational in infrastructure, applied widely, easy to use, be suitable for electrician's measuring instruments such as multimeter, oscillograph and use.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to Fig. 1 and Fig. 2, a kind of multicore formula test pencil, comprise a body 1, be provided with four chutes 4 at a body 1 one ends, be provided with screens 5 in each chute 4 the inner, in a body 1 port end cap 3 is housed, is provided with fairlead in end cap 3, a body 1 other end is equipped with nib 2 by the taenidium retaining ring, be connected the guide plate 10 that conductor is housed on the component level 9 at nib 2 with a body 1 inner chamber, be provided with four guide holes 11 on guide plate 10, be set with pen core 6 in each guide hole 11, these pen core 6 one ends are insulator handle end 7, the other end is a conductor end 8, at this conductor end 8 test rod is housed, is enclosed within a body 1 chute 4, on the pen core 6 of 10 on handle and guide plate, spring 12 is housed at the handle end 7 of pen core 6.On every pen core 6 conductor ends 18, load onto as shown in Figure 3 needle-like test rod 14, shaft-like test rod 15, the tubulose test rod 16 and the test rod of sheet detection bar 17 as shown in Figure 6 as shown in Figure 5 as shown in Figure 4 respectively, connect with measuring instrument by guide plate 10 and lead 13, when testing circuit, can be according to the detected circuit actual conditions, select respective detection bar in the pen, handle is dialled in screens 5 places of the location of chute 4, test rod will stretch out from nib 2.Select needle-like test rod 14 can thrust the electric circuit inspection of soft insulation course or connection plug-in unit; Select shaft-like test rod 15 identical, be suitable for the detection of general circuit with existing test rod; Select tubulose test rod 16, because of bar outward for the insulator middle conductor is provided with aperture, with the hole to circuit component pin and solder joint, the circuit at suitable detecting element pin and solder joint place; Sheet detection bar 17 because of insulator simultaneously be provided with sheet metal, so sheet detection bar 17 is the thin slice that conductor surface and three form for insulator structure by one side, be applicable to integrated circuit pin is detected, can be close not many because of pin, cause because of detecting short circuit between the pin, influence detects effect.The detecting pen that integrates needle-like test rod 14, shaft-like test rod 15, tubulose test rod 16 and sheet detection bar 17, can be easily, fast, accurately, test circuit safely.The utlity model has characteristics rational in infrastructure, applied widely, easy to use, be fit to electrician's measuring instruments such as multimeter, oscillograph and use.
