Description
Technical field
The utility model relates to a kind of IC-card wiring board and detects conversion equipment, belongs to the electronic test equipment technical field.
Background technology
In IC-card wiring board production run, need the current/voltage of its region of interest be detected, thereby the performance and the quality of judgement IC-card wiring board generally all adopt multimeter and adjustable stabilized voltage supply to cooperate now and carry out.When between the function of using multimeter and range, changing, all use machine carousel point to contact conversion, as long-time ordinary use with point, the machine carousel contact point can wear and tear, cause loose contact, half a year or shorter time just need to change multimeter, have increased production cost.When using adjustable stabilized voltage supply, need regulate voltage, personal error can appear during adjusting, for reduce personal error as far as possible, just need to spend the longer time and increase manpower to go accurate adjusting.
Summary of the invention
The purpose of this utility model provides a kind of IC-card wiring board and detects conversion equipment, at and solve exist in existing the detection cause loose contact because of the wearing and tearing of multimeter machine carousel contact point, need often to change multimeter, adjustable stabilized voltage supply is regulated deficiencies such as personal error occur, realization can be changed required gear and voltage-regulation fast, increases work efficiency, and reduces production costs, reduce personal error, thereby reach the accuracy of detection.
The purpose of this utility model is achieved through the following technical solutions, and a kind of IC-card wiring board detects conversion equipment, comprises shell, multimeter, regulated power supply, it is characterized in that the relevant gear of multimeter connects the locking switch that is provided with through lead-in wire; The output voltage of adjustable stabilized voltage supply is connected to some resistance adjustable resistances of setting, required voltage regulated earlier being connected to locking switch after fixing by adjustable resistance, access light emitting diode and the current-limiting resistance that is connected in series with light emitting diode between the tie point of each adjustable resistance and corresponding locking switch and ground.
The utility model is on the basis of multimeter and regulated power supply, by locking switch is set, replace the machine carousel in the multimeter, overcome the loose contact that causes because of the wearing and tearing of machine carousel contact point, by some adjustable resistances are set, regulate in advance and fix required voltage, no longer occur because of regulating the personal error of bringing at any time, the utility model is simple in structure, dependable performance, help improving work quality and work efficiency, provide condition effectively easily for detecting the IC-card wiring board.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams;
Among the figure, A regulated power supply, B1-B7 locking switch, C multimeter, R1-R4 adjustable resistance, LED1-.LED4 light emitting diode, R5-R8 current-limiting resistance.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is made of shell, adjustable resistance R1-R4, LED 1-.LED4, locking switch B1-B4, multimeter C, regulated power supply regulated power supply.Adjustable resistance R1-R4 is placed in the shell, and with LED 1-.LED4, locking switch R1-R4 places on the housing face-plate, places 3 ' to put available regulated power supply 1 ' o'clock of switch B5, places 2 ' to be transformed into the utility model.The resistance of adjustable resistance R1, R2, R3, R4 etc. is adjusted to the resistance of required voltage, (as 3.6V, 3.05V, 3V, 2.85V etc.).As that voltage of needs, achieve the goal according to corresponding that the switch of voltage such as B1, B2, disconnection, closures such as B3, B4.After the closure, light emitting diode LEB1, the LED2 of that voltage status, LED3, LED4 light thereupon; Conversion is to find out as the gear and the common point of correspondences such as 200mA, 200 μ A in the multimeter between the electric current, with machine carousel in the gear contact point disconnect, locking switch B6 junction has fork to represent the contact to disconnect, be connected to the locking switch B7 in the shell, disconnect and represent 200mA, on behalf of 200 μ A, closure reach the current conversion purpose.
