The utility model provides a voltage and current measuring device of an entire car. The voltage and current measuring device comprises a battery jar pile head (1) for connecting with a wire bundle at a negative electrode of a battery jar, a sleeve (2) for connecting with a pile head at the negative electrode of the battery jar, an insulation piece arranged between the battery jar pile head (1) and the sleeve (2) and used for insulating the conduction of the battery jar pile head (1) and the sleeve (2), a switch (4) for turning on or turning off a circuit between the battery jar pile head (1) and the sleeve (2), and a leading-out wire (5) for connecting with a multimeter to measure a current and a voltage.
Description
Technical field
The utility model relates to the measurement mechanism of electric current and voltage, relates in particular to the measurement mechanism of the electric current and voltage that is applied to car load.
Background technology
Along with the development of automotive electronic technology, various types of electronic components are increasing on the car load.The control quiescent current also just becomes a very crucial technical indicator.In the performance history of car load, the measurement of quiescent current also is an indispensable link.The measurement mechanism of vehicle voltage electric current is exactly a kind of convenient, the efficient and accurate instrument that designs at this problem.Also can alleviate tester's working strength simultaneously.
Present measuring method mainly contains two kinds:
1) directly the reometer series connection is inserted between storage battery negative pole and the negative pole pile crown.The shortcoming of this method is that the stage that electric current is bigger before the car load dormancy burns out reometer easily.
2) use the current clamp of induction type to carry out current measurement.The shortcoming of this method is existing current clamp in the current measurement of mA level, and precision is compared reometer big gap.Cause test accuracy not high.
The utility model content
At above-mentioned technical matters, the purpose of this utility model be to provide a kind of stable and reliable for performance and can be convenient, efficiently, the measurement mechanism the accurately electric current and voltage of car load measured.
For realizing above-mentioned purpose, the technical solution adopted in the utility model is as follows:
A kind of proving installation of vehicle voltage electric current comprises: the pile head of storage battery that is used to connect storage battery negative pole wire harness; Be used to connect the sleeve of storage battery negative pole pile crown; Between described pile head of storage battery and described sleeve, be used for the insulating part of isolated conducting between the two; The switch that makes conducting between described pile head of storage battery and the described sleeve or open circuit; And be used to connect the extension line of multimeter with the measurement of carrying out electric current and voltage.
According to said structure, owing to comprise: the pile head of storage battery that is used to connect storage battery negative pole wire harness; Be used to connect the sleeve of storage battery negative pole pile crown; Between described pile head of storage battery and described sleeve, be used for the insulating part of isolated conducting between the two; The switch that makes conducting between described pile head of storage battery and the described sleeve or open circuit; And be used to connect the extension line of multimeter with the measurement of carrying out electric current and voltage, therefore when adopting the measurement mechanism of vehicle voltage electric current of the present utility model, also do not enter the stage of dormant state at car load, can make switch conduction, pass through reometer to avoid big electric current.And get final product cut-off switch after electric current diminishes when the car load load reduces, reometer is sealed in the loop measure.
In addition, in the proving installation of above-mentioned vehicle voltage electric current, described switch is preferably the screw-type rotary switch.
According to said structure, the break-make of utilizing the screw-type rotary switch can control easily between pile head of storage battery and the sleeve concerns; Because the car load current values is bigger sometimes, therefore adopt the common relatively touch switch of switch designs of screw-type that can be arranged longer serviceable life at this.

Embodiment
Below embodiment of the present utility model is elaborated.Following embodiment only is an example of technical solutions of the utility model, should not be interpreted as the qualification to the utility model protection domain.
As shown in Figure 1, the proving installation of the vehicle voltage electric current of present embodiment comprises: the pile head of storage battery 1 that is used to connect storage battery negative pole wire harness; Be used to connect the sleeve 2 of storage battery negative pole pile crown; Between pile head of storage battery 1 and sleeve 2, be used for the insulating part 3 of isolated conducting between the two; The switch 4 that makes conducting between pile head of storage battery 1 and the sleeve 2 or open circuit, and be preferably the screw-type rotary switch; And be used to connect the extension line 5 of multimeter with the measurement of carrying out electric current and voltage.
Below the use of the proving installation of vehicle voltage electric current is described:
When the proving installation of the vehicle voltage electric current that utilizes present embodiment is measured quiescent current, at first, the survey instrument of this vehicle voltage electric current is installed on the storage battery negative pole.Say more more specifically, just storage battery sleeve 2 be placed on the negative pole pile crown of storage battery, and with the negative line collar headgear of storage battery on the pile head of storage battery 1 of measurement mechanism.
Then, after closing all loads of car load, make switch 4 closures, thereby make the positive and negative poles of battery conducting.(promptly adopt the situation of screw-type rotary switch) in the present embodiment, exactly screw-type rotary switch 4 is tightened, make the pile head of storage battery end and the conducting of storage battery socket end of measurement mechanism, thereby make conducting between the both positive and negative polarity of storage battery.Thus, can make bigger car load electric current of test initial stage from the storage battery internal circulation, by the time after electric current diminishes, distinguish the extension line at fastening means two ends again with multimeter, switch 4 is disconnected, make the car load electric current from the multimeter internal circulation, by the time car load electric current trend stable after, can stably measure the quiescent current of car load.
According to said structure, when the measurement mechanism of the vehicle voltage electric current that adopts present embodiment, also do not enter the stage of dormant state at car load, switch can be tightened, pass through reometer to avoid big electric current.And switch can be unscrewed after electric current diminishes when the car load load reduces, reometer is sealed in the loop measure.
And in the present embodiment, the break-make of utilizing the screw-type rotary switch can control easily between pile head of storage battery and the sleeve concerns; Because the car load current values is bigger sometimes, therefore adopt the common relatively touch switch of switch designs of screw-type that can be arranged longer serviceable life at this.
The foregoing description should not be interpreted as qualification of the present utility model, and in the scope that does not break away from purport, change arbitrarily all is allowed to.
