Abstract
The utility model relates to a regularly closed lifting switch, which is characterized in that a pair of moving and static contacts is provided, and the moving contact sheet of the utility model is a sheet-shaped rocker made from copper. The utility model has the advantages that silver consumption can be saved by 75%, the actions of switching on and the switching off are fast and agile, and the utility model has a wide purpose.
Description
The utility model relates to a kind of normally closed type electric switch.
Normally closed type commonly used lifts switch and adopts two pairs of contacts, i.e. two moving contacts and two fixed contacts, and the place, contact of each contact is coated by ag material, and its defective is that the contact number is many, and the precious metal consumption is big.
The purpose of this utility model provides a kind ofly to be had only a pair of dynamic and static contact, adopts the normally closed type of a silver contact to lift switch, and switch silver consumption is reduced significantly.
The design's normally closed type lifts switch, comprise housing 1, cover plate 2, push rod 3, support and compress the spring 4 of push rod 3, moving contact 5, fixed contact 6, cover plate hold-down screw and the conducting strip that is connected with moving contact or fixed contact, it is characterized in that being provided with a moving contact 5 and a fixed contact 6, moving contact 5 adopts the copper sheet fork that has arc on it, and fixed contact 6 is arranged in housing 1 cavity bottom, and push rod 3 is for being inverted the T body, its underpart has a horizontal blind hole that is used to arrange spring 7 and slide block 8, the bending place of conducting strip 5 ' on slide block 8 extended lines is provided with arc, and its end embeds in housing 1, and moving contact 5 is by slide block 8 and conducting strip 5 ' clamping.Slide block 8 outer ends are spherical surface body, and slide block 8 can adopt spheroid, as ball commonly used etc.Cover plate 2 by screw on housing 1.
Conducting strip 5 ', form 30 °～45 ° angles between inclined-plane and the vertical line in the partly bending inclination all laterally of arc place upper and lower, because the effect of spring 4, dynamic and static contact is normally closed, and when lifting push rod 3, push rod 3 moves down, and dynamic and static contact disconnects.Lift and stop, push rod 3 resets, and dynamic and static contact returns to closure state immediately.
Prior art is provided with 4 and contains silver contact, and this programme only has 6 employings of 1 fixed contact to contain silver contact, saves silver consumption 75%; Simultaneously, its lower end linear velocity is bigger during as the action of the fork of moving contact 5, makes the switch switching motion quick fast.
Fig. 1 lifts the construction of switch schematic diagram for this normally closed type, and moving contact 5 is in the moment that breaks away from fixed contact 6 among the figure.
Fig. 2 is the vertical view of this switch.
Claims (3)
1, a kind of normally closed type lifts switch, comprise housing 1, cover plate 2, push rod 3, support and compress the spring 4 of push rod, moving contact 5, fixed contact 6, cover plate hold-down screw and with moving, the conducting strip that fixed contact connects, it is characterized in that: moving contact 5 and fixed contact 6 respectively are provided with one, moving contact 5 adopts the copper sheet fork that has arc on it, and fixed contact 6 is arranged in housing 1 cavity bottom, and push rod 3 is for being inverted the T body, its underpart has a horizontal blind hole that is used to arrange spring 7 and slide block 8, the bending place of conducting strip 5 ' on slide block 8 extended lines is provided with arc, and its end embeds in housing 1, and moving contact 5 is by slide block 8 and conducting strip 5 ' clamping.
2, according to the switch that lifts of claim 1, it is characterized in that: described slide block 8 its outer ends are spherical surface body.
3, according to the switch that lifts of claim 1, it is characterized in that: described slide block adopts spheroid.
