The switch testing device can accurately control the closing and the connecting of a switch for guaranteeing the stability and the reliability of test performance.
Description
Technical field
The utility model relates to the field tests of circuit structure part or equipment, exactly is meant a kind of switch test device.
Background technology
In order to guarantee product quality, switch must carry out the test in switch performance and life-span, promptly switch is repeated the on-off action to test its usability and life-span.But present switch test device is by pure hardware controls, and driven by direct current generator, the volume under pressure of gauge tap does not have tutorial function artificially, can't realize accurately judging that whether switch connects, even sometimes can not depress switch, the stability of test is poor.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of switch test device, and accurately the closure of gauge tap is connected, to guarantee the stability and the reliability of test performance.
In order to solve above technical matters, the switch test device that the utility model provides, comprise switch testing anchor clamps and functional unit, the rotating disk that described switch testing anchor clamps include motor and are connected with motor by machine shaft, also comprise the rotation micro-adjusting mechanism of control dial rotation distance, described rotation micro-adjusting mechanism is connected with described motor.
Preferably, switch test device also comprises switch contact display device, and described switch contact display device is connected with the circuit of each switch to be tested.
Preferably, switch test device also comprises micro computer, and described rotation micro-adjusting mechanism is by described microcomputerized control, and described micro computer is provided with the direction setting unit of control motor sense of rotation and dial rotation apart from control module; Described micro computer is connected with described functional unit; Described micro computer is provided with display screen.
Preferably, described micro computer is provided with switch contact display unit.
Preferably, described display screen be LED display,
Preferably, described motor is a stepper motor; Described functional unit is some buttons.
Preferably, switch test device also comprises shell.
The switch test device that the utility model provides comprises the rotation micro-adjusting mechanism of control dial rotation distance, and described rotation micro-adjusting mechanism is connected with described motor.Compared with prior art, the switch test device that the utility model provides is controlled the dial rotation distance by rotating micro-adjusting mechanism, thereby the connection distance of gauge tap contact, and then the accurately closure connection of gauge tap artificially is to guarantee the stability and the reliability of test performance.
Especially, the switch test device that the utility model provides can be provided with the distance of dial rotation on apart from control module in the dial rotation of micro computer, and show the contact show state of each switch on display screen, thereby guarantee the connection of switch, realize the stability of switch testing.

Embodiment
For those skilled in the art can understand technical scheme provided by the utility model better, set forth below in conjunction with specific embodiment.
See also Fig. 1, this figure is the structural representation of switch test device in the utility model.
The switch test device that the utility model provides, except comprising switch testing anchor clamps 1 and some action buttons 3, the rotating disk 11 that switch testing anchor clamps 1 include stepper motor and are connected with stepper motor by machine shaft, also comprise rotation micro-adjusting mechanism, rotate micro-adjusting mechanism and be connected with motor by microcomputerized control dial rotation distance.Micro computer is provided with LED display 2, and micro computer is provided with direction setting unit, rotating disk 11 rotation distance control modules and the switch contact display unit of control motor sense of rotation.Switch test device also comprises shell 4, switch testing anchor clamps 1 and micro computer can be encapsulated in the shell.
See also Fig. 2, Fig. 3, Fig. 2 is the work synoptic diagram of switch testing anchor clamps among Fig. 1; Fig. 3 is the duty chart of display screen among Fig. 1.
The workflow of the switch test device that the utility model provides is as follows:
Before switch testing anchor clamps 1 are started working, earlier switch 5 is fixed on the switch testing anchor clamps 5, because this device is provided with the rotation micro-adjusting mechanism, rotate the rotation distance that micro-adjusting mechanism is regulated rotating disk 11 by action button 3 controls.The groove surface of the rotating disk 11 of switch testing anchor clamps 1 contacts with the first switch contact 51, press action button at every turn, rotating disk 11 certain slight distance that turns left, as 0.15 millimeter, and promote the first switch contact 51 and be moved to the left, be connected up to the first switch contact 51 and second switch contact 52, and realize determining the closure connection of switch contact with this.
The disconnection (being broken as 0) or closure (closure the is 1) situation of " disconnected 0 closes 1 " the row meeting display switch in the duty chart of the display screen of Fig. 3.According to the aforesaid operations process, in the time of the push button, observe the data in " disconnected 0 closes 1 " row in the table, whether become 1.As in the chart of Fig. 3, No. two switches and No. five switches are pairing should to show " 1 " by row, illustrate that No. two switches and No. five switches are closed on-state at this moment, and other switch still was in off-state; Continue the push button, make whole switches all show " 1 " after, determine that the process that switch closure is connected finishes; Above process is finished under " state is set ", so in the inside, " information indicating " hurdle, show " setup state "; After determining that all switches can closedly be connected, press " beginning " (START) button, the switch testing anchor clamps just can have been started working according to the amount of being pressed into of determining the switch closure connection.
Above setting all is to realize that by three action buttons above the switch stationary installation action button that has has dual-use function, function difference under different states.
Certainly; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
