Abstract
The utility model discloses a kind of car appliances power source check device, including handwriting, bulb, metal penpoint, connecting wire, metallic conduction folder and diode；The handwriting cylindrical in shape, is internally provided with a bulb；The leg of bulb one is connected with metal penpoint, and another leg is connected to the positive pole of diode；The negative pole of the diode is connected with metallic conduction by connecting wire and pressed from both sides.For the utility model using on the end pin for needing to check in metal penpoint insertion sheath, metallic conduction presss from both sides the negative pole for being connected to vehicle, simple to operate, safe to use laborsaving, improves electrical equipment and checks efficiency；Meanwhile the both positive and negative polarity of power supply can be simply judged using the diode built in handwriting.
Description
Technical field
A kind of vehicle power supply detection instrument is the utility model is related to, specifically a kind of car appliances power source quickly checks dress
Put.
Background technology
At present, based on power detecting is detected with instrument on vehicle, for some simple power detectings, corresponding work is lacked
Tool., it is necessary to be checked with loaded checking tool in the examination of the empty electricity of vehicle power supply, power supply could be more accurately found
Situation.In order to meet needs that current car appliances power source quickly checks, a kind of scheme is now provided.
Utility model content
The purpose of this utility model is to provide a kind of labour-saving car appliances power source inspection dress simple to operate, safe to use
Put.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of car appliances power source check device, including handwriting, bulb, metal penpoint, connecting wire, metallic conduction folder with
Diode；The handwriting cylindrical in shape, is internally provided with a bulb；The leg of bulb one is connected with metal penpoint, separately
One leg is connected to the positive pole of diode；The negative pole of the diode is connected with metallic conduction by connecting wire and pressed from both sides.
The beneficial effects of the utility model：The utility model utilizes the end pin for needing to check in metal penpoint insertion sheath
On, metallic conduction presss from both sides the negative pole for being connected to vehicle, simple to operate, safe to use laborsaving, improves electrical equipment and checks efficiency；Meanwhile
The both positive and negative polarity of power supply can be simply judged using the diode built in handwriting.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that being further described below in conjunction with the accompanying drawings to the utility model.
Fig. 1 is front view of the present utility model；
Fig. 2 is Fig. 1 left view；
Fig. 3 is Fig. 1 schematic diagram.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of car appliances power source check device, as Figure 1-3, including handwriting 1, bulb 2, metal penpoint 3, connection lead
Line 4, metallic conduction folder 5 and diode 6；
The cylindrical in shape of handwriting 1, is internally provided with a bulb 2, and the leg of bulb 2 one is connected with metal penpoint 3, metal pen
Point 3 is used to stretch into electrical equipment sheath, and 2 another leg of bulb is connected to the positive pole of diode 6, and the negative pole of diode 6 passes through connection
Wire 4 is connected with metallic conduction folder 5；
Above-mentioned technical proposal specific operation process is as follows：When checking power supply, metal penpoint 3, which is inserted in sheath, to be needed to examine
On the end pin looked into, metallic conduction folder 5 is connected to the negative pole of vehicle, if bulb lights, illustrates there is electricity at this；Meanwhile in handwriting 1
The both positive and negative polarity of power supply can simply be judged by installing diode 6；The device is simple to operate, safe to use laborsaving, improves electrical equipment
Check efficiency.
Above content is only to the utility model structure example and explanation, the technology people of affiliated the art
Member is made various modifications or supplement to described specific embodiment or substituted using similar mode, without departing from reality
With new structure or surmount scope defined in the claims, the scope of protection of the utility model all should be belonged to.
