The utility model is characterized in that a control needle resetting device is magnetic blocks which are installed on the utility model or are relatively installed on meter needles and the spacing needles, or a plurality of small material blocks which can be magnetized. The utility model is also provided with a control assembly which is composed of a relay assembly and a thyristor assembly. The utility model conquers the disadvantages in prior art that a spiral spring resetting device is afraid of shock and is easy to break, and the manufacture is complicated; thereby, the structure is simplified, and the service life is prolonged.
Description
The utility model relates to a kind of indicator electric contact controller, comprises fixedly position-limited needle and two reducible movable control pins of contact-carrying of the position adjustable of two contact-carryings, and it is specially adapted to tensimeter and thermometer.
This existing electric contact controller, resetting of two movable control pins realized by miniature volute spring.Its shortcoming is: the back-moving spring shockproof properties is poor, fatigue break easily, and cause complex structure.In addition because the structural limitations of pin upper contact can not be sent more powerful electric signal.
The purpose of this utility model is to provide a kind of improved indicator electric contact controller for this reason, and it has overcome the defective of shockproof properties difference in the prior art, and makes designs simplification, low cost of manufacture, and reliable operation long service life.
The further purpose of the utility model is, overcomes the little defective of power in the prior art, thereby can directly apply in the industrial control circuit, and then simplified the structure setting of control system, helps the popularization and the development of robotization control.
Fundamental purpose of the present utility model is so to realize: a kind of indicator electric contact controller, comprise: the fixedly position-limited needle of transposing of two contact-carryings and two reducible movable control pins of contact-carrying, it is characterized in that: the resetting means that is used for movable control pin is little magnetic patch and the corresponding list index that is placed in that is placed on the control pin, little magnetic patch on the position-limited needle or magnetisable material fritter.
One of the utility model realizes that the preferred version of further purpose is, also equips a Control Component and general directly is installed together with the indicator support.
Another preferred version of the utility model is, two control pins (first, second) are installed in the both sides of indicator, settle two little magnetic patch on reset little magnetic patch and the two control pins opposed in this side of indicator, on first position-limited needle with the little magnetic patch corresponding arrangement one little magnetic patch of first control on the pin, on second position-limited needle with the corresponding arrangement one little magnetic patch of little magnetic patch of the second control pin; Described Control Component is made of thyristor (controllable silicon) assembly; Circuit structure is: power supply one end is connected to behind the diac common point of two control pins again by two resistance in seriess (the 3rd, the 4th); First position-limited needle is connected to the control utmost point of the first intergranular pipe, the first thyristor T
1-2Hold to the power supply other end its T
1-1Hold in parallel and be a control end with first resistance and the first capacitances in series assembly; Second position-limited needle is connected to second thyristor control utmost point, its T
2-2End is connected to the power supply other end, its T
2-1End and the parallel connection of second resistance, the second capacitances in series assembly and be another control end.
This reality has novel another preferred version to be, first, second control pin is installed in indicator the same side, and described Control Component is made of a relay, and its circuit structure is: relay one end is connected on two control pins, and the other end is connected to power supply one end; The power supply other end is connected with the relay moving contact with second position-limited needle; First position-limited needle links to each other with normally opened contact.
Another preferred version of the utility model is, first, second control pin be placed in the both sides of indicator and the first control pin between first, second position-limited needle and the little magnetic patch that leans against the usefulness that for this reason resets on first position-limited needle do corresponding the layout; Control Component is made up of two relays, and circuit structure is: first relay, one end is connected to first position-limited needle, and the other end and power supply one end and a moving contact are linked to be common point; The moving point of the power supply other end and second position-limited needle and second relay is linked to be common point; Second relay, one end and its normally opened contact and two control pins are linked to be common point, and the other end is connected to the first relay normally closed contact.
From several preferred versions of the present utility model as can be seen, they have finished goal of the invention well, have solved deficiency of the prior art, and originally back-moving spring generally is a screw type, so make not only complicated, and material requirements is very high, causes the difficulty of arranging simultaneously, more is unable to undergo oscillating action repeatedly, adopt the resetting means of the little magnetic patch of coupling type, structure is simplified greatly, and the position that takes up room simultaneously dwindles greatly, thereby structure is provided with compact and reasonable more.In addition, be provided with Control Component, enlarged power controlling greatly, and the AC and DC circuit all can be used and power can enlarge several times even tens of times.And the electric power between the contact can reduce only to need very little electric current as the control utmost point of thyristor Control Component greatly,, thus the electric spark phenomenon also weakens greatly until elimination, and then improved the conducting quality and prolonged mission life.Owing to can directly carry out powerful control, thereby range of application enlarges obviously.
Below, by the embodiment in the accompanying drawing, describe the utility model in detail.
