Description

An a kind of novel examination lamp structure

Technical field

The utility model relates to passenger vehicle light fixture test field, is specifically related to an a kind of novel examination lamp structure.

Background technology

Test is the important means of testing product, bright light test must be done after present stage passenger vehicle light fixture maintenance, need power lead be crimped onto on power supply terminal during test, switch on power again and detect whether bright light is normal, because testing front palpus crimping lead wire, after test neutralization test, must wire be dismantled, how loaded down with trivial details can not showing at least if try lamp quantity, if but bulge test, operate and just seem cumbersome, detection efficiency is extremely low.

Utility model content

In order to need frequently to disconnect wire when solving test that existing method exists, operate cumbersome, the technical matters of impact examination lamp efficiency, the utility model provides an a kind of novel examination lamp structure.

The technical scheme that the utility model technical solution problem is taked is as follows:

An a kind of novel examination lamp structure comprises: mutually isostructural black pen and red pen, protective tube and plug, and red pen is electrically connected with protective tube by wire, and protective tube is electrically connected with plug by wire, and black pen is electrically connected with plug by wire; Described black pen or red pen comprise insulation a shell, contact, spring, contact guide pin bushing, card and bonding conductor, and the front end of contact is cone, and spring housing is at the medium position of contact; Contact guide pin bushing is enclosed within spring outside, and contact guide pin bushing is fixed on the front end of an insulation shell inner chamber; Card is arranged in the inner chamber of an insulation shell, and is fixed on the afterbody of contact guide pin bushing; The front end of spring is fixed on contact, and rear end is spacing by card; The cone front end of contact and right cylinder tail end are all placed in the outside of contact guide pin bushing, bonding conductor is placed in the medium position of an insulation shell inner chamber, the tail end of bonding conductor causes the outside of a shell by wire, have gap between the front end of bonding conductor and the tail end of contact, the width in this gap be less than or equal to spring along an insulation shell lumen shaft to maximum compression distance.

The beneficial effects of the utility model are: this examination lamp structure can improve examination lamp efficiency more than 3 times, reduces the examination lamp time, and can ensure examination lamp process operation safety.

Fig. 2 is longitudinal cross-sectional schematic of black pen in the utility model or red pen.

Fig. 3 is the structural representation of an a kind of novel examination lamp structure of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 to Figure 3, an a kind of novel examination lamp structure of the utility model comprises: mutually isostructural black pen and red pen, protective tube 7 and plug 8, red pen is electrically connected with protective tube 7 by wire, and protective tube 7 is electrically connected with plug 8 by wire, and black pen is electrically connected with plug 8 by wire; Described black pen or red pen comprise insulation a shell 1, contact 2, spring 3, contact guide pin bushing 4, card 5 and bonding conductor 6, and the front end of contact 2 is cone, and spring 3 is enclosed within the medium position of contact 2; It is outside that contact guide pin bushing 4 is enclosed within spring 3, and contact guide pin bushing 4 is fixed on the front end of an insulation shell 1 inner chamber; Card 5 is arranged in the inner chamber of an insulation shell 1, and is fixed on the afterbody of contact guide pin bushing 4; The front end of spring 3 is fixed on contact 2, and rear end is spacing by card 5; The cone front end of contact 2 and right cylinder tail end are all placed in the outside of contact guide pin bushing 4, bonding conductor 6 is placed in the medium position of an insulation shell 1 inner chamber, the tail end of bonding conductor 6 causes the outside of a shell 1 by wire, have gap between the front end of bonding conductor 6 and the tail end of contact 2, the width in this gap be less than or equal to spring 3 along an insulation shell 1 lumen shaft to maximum compression distance.

The course of work of the utility model examination lamp structure is: be first inserted in supply socket by plug 8, then experimenter's left hand holds black pen, the right hand holds red pen, the contact 2 of black pen is directly touched the zero line side of power supply terminal, the contact 2 of red pen directly touches any one live wire end of power supply terminal, then respective contact 2 is firmly pressed down by a respective shell 1, and then respective spring 3 is compressed, make the front end in contact of the tail end of contact 2 and bonding conductor 6, and then switch on power, lamp power terminal obtains electric, realizes bright light.Red for right hand pen is removed power supply terminal, and contact 2 and bonding conductor 6 separate by the elastic force relying on spring 3 to recover, and then cut off the electricity supply.Then, then the contact 2 of red for right hand pen is moved on to the next live wire end of power supply terminal, carry out examination lamp according to aforesaid same procedure, the like, realize the object of examination lamp fast.If have short circuit phenomenon to occur when testing, then protective tube 7 meeting automatic cut-off power, plays the object of the red pen of protection and black pen and light fixture.
