Abstract
The utility model discloses a novel test meter pen, which comprises a test meter pen main body, a shell which is sheathed at the outside of the test meter pen and a probe protector, wherein a test probe of the test meter pen main body is extended out of the front end of the shell, and the probe protector is arranged on the test probe to prevent users from being electrically shocked when the test meter pen is not used for testing. The novel test meter pen is reasonable is structure, leads a protecting cover to be capable of being inwards shrunken by contacting the test probe with an objective to be tested only with a small force due to the probe protector and a protecting pipe when the test meter pen is used for testing, reduces the exposed parts of the test probe as much as possible due to the reset function of a protecting spring, and leads the test probe to be covered by the protecting cover after the novel test meter pen is used to prevent the users from being electrically shocked. When the electric current which passes through the test meter pen is larger than the rated current, a circuit can be automatically cut off by the protecting pipe, so that the danger can be avoided in case of misoperation.
Description
Technical field
The utility model relates to the test test pencil, particularly a kind of novel test test pencil that is provided with the probe protective device.
Background technology
In the prior art, electronic measuring instruments such as multimeter are often used in work and life.Traditional test test pencil all is not provided with protective device; people are behind electronic measuring instruments such as use multimeter, if because reasons such as carelessness will not tested test pencil and be taken away, this test test pencil still is and the contacted words of electrified body; be easy to get an electric shock, thereby jeopardize life safety.Some multimeter producer recognizes such potential safety hazard, also there is at present the test test pencil of part to be provided with the pluggable pen cap on the market, but such pen cap uses inconvenient, the user equally can be owing to neglect and forget the test test pencil is separated with electrified body, can forget equally after test the pen cap is entangled the test test pencil, be difficult to avoid the danger of getting an electric shock.In addition, at present test test pencil on the market is not provided with protective tube, when the electric current by test pencil during greater than rated current, and the danger that is easy to get an electric shock.
The utility model content
The purpose of this utility model is, a kind of novel test test pencil reasonable in design is provided, this novel test test pencil is provided with a probe protective device, protective sleeve covers test probe, protective sleeve is stressed when test can bounce back, thereby exposes test probe, and the test back makes test probe and electrified body touching as long as the user no longer applies power, protective sleeve ejects automatically test probe is separated with electrified body, and is safe and reliable; And in this novel test test pencil, be provided with a protective tube, when by electric current during greater than rated current, protective tube can be from cutting off, thereby cause danger when avoiding maloperation.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of novel test test pencil; it comprises that a test pencil body and is set in the shell of this test pencil outside; the test probe of this test pencil body stretches out the leading section of this shell, and it comprises that also a user that avoids who is arranged on the described test probe has the probe protective device of Danger Electric shock risk when non-test.
As further improvement of the utility model; described probe protective device comprises a protection spring and a protective sleeve cylindraceous of being made by insulating material; the rear end of described test probe is provided with one first boss; the rear end of described protective sleeve is provided with one second boss; described protection spring and protective sleeve are enclosed within on the described test probe successively; the two ends of this protection spring prop up first boss and second boss respectively, and described protective sleeve covers the front end of described test probe.
As further improvement of the utility model, described shell comprises procapsid and back casing, and the internal diameter of described procapsid leading section is less than the external diameter of described second boss.
As further improvement of the utility model, described test pencil body comprises a test probe, a protective tube, a copper contact, a protective tube spring and a copper sheathing successively by front end to the rear end, described protective tube spring places this copper sheathing, described copper contact one end props up the protective tube spring, the other end of this copper contact contacts with protective tube, and the other end of described protective tube contacts with described test probe.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, be provided with probe protective device and protective tube, in test process, only need test probe to be contacted with measured object with very little power, protective sleeve will inwardly contract, owing to protect the reset response of spring, can reduce the exposed parts of test probe as far as possible, use the back protective sleeve test probe can be covered, thereby avoided Danger Electric shock risk; When the electric current by the test test pencil during greater than rated current, protective tube can cut off circuit automatically, thereby causes danger when avoiding maloperation.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings

Fig. 2 is an explosive view of the present utility model.
Embodiment
Embodiment: see Fig. 1 and Fig. 2; a kind of novel test test pencil of the utility model; it comprises that a test pencil body 1 and is set in the shell 2 of this test pencil body 1 outside; the test probe 11 of this test pencil body 1 stretches out the leading section of this shell 2, and it comprises that also a user that avoids who is arranged on the described test probe 11 has the probe protective device of Danger Electric shock risk when non-test.
Described probe protective device comprises a protection spring 31 and a protective sleeve cylindraceous 32 of being made by insulating material; the rear end of described test probe 11 is provided with one first boss 111; the rear end of described protective sleeve 32 is provided with one second boss 321; described protection spring 31 and protective sleeve 32 are enclosed within on the described test probe 11 successively; the two ends of this protection spring 31 prop up first boss 111 and second boss 321 respectively, and described protective sleeve 32 covers the front end of described test probe 11.
Described shell 2 comprises procapsid 21 and back casing 22, and the internal diameter of described procapsid 21 leading sections is less than the external diameter of described second boss 321.
Described test pencil body 1 comprises a test probe 11, a protective tube 12, a copper contact 13, a protective tube spring 14 and a copper sheathing 15 successively by front end to the rear end, described protective tube spring 14 places this copper sheathing 15, described copper contact 13 1 ends prop up protective tube spring 14, the other end of this copper contact 13 contacts with protective tube 12, the other end of described protective tube 12 contacts with described test probe 11, and a termination of described copper sheathing 15 has a test connecting line 16.
When using the utility model; with test probe 11 touching determinands; thereby the stressed retraction of protective sleeve 32 front ends; thereby test probe 11 exposes to contact with determinand and begins test; because the return action of protection spring 31; can reduce the exposed parts of test probe 11 as far as possible; and protective sleeve 32 can automatic ejection cover test probe 11 after test; thereby reduced the danger of getting an electric shock; when the electric current by the test test pencil during greater than rated current; protective tube 12 can cut off circuit automatically, thereby causes danger when avoiding maloperation.
