Abstract
Disclosed is a pressure relay with a butterfly spring and a contact plate, including an acting force adjusting system and a released force adjusting system. The system consists of an acting force adjusting device and a released force adjusting device. The acting force adjusting device comprises an adjusting screw, a spring, an ejector pin and a contact plate with a positioning hole. The released force adjusting device comprises an ejector block, an adjusting screw and a spring. The acting force and the released force are adjusted through respectively rotating the screws, ensuring the currency of the product to be greatly improved. The reject rate and the production cost are reduced. The work efficiency is increased.
Description
The utility model relates to a kind of butterfly spring-contact chip pressure switch, particularly the butterfly spring of band action force and release force Adjustment System-contact chip pressure switch.
Existing butterfly spring-contact chip pressure switch is to utilize the stressed upset of butterfly spring to drive contact chip moment motion by pushing block, is installed in the contact moment contact energising simultaneously on the contact chip.When power was reduced to certain certain value, the butterfly spring was replied, contact chip and contact moment disengagement outage.This pressure switch has little, the advantage of high precision of volume, but disadvantage is that encapsulation back action force and release force are definite values, can not adjust, this just causes in the production percent defective very high, use especially at a certain temperature, this two power will be drifted about again, cause new defectively, as the main frame of packing into will influence the use of main frame.
The purpose of this utility model is to be to provide a kind of butterfly spring with action force and release force Adjustment System-contact the chip pressure switch, under normal circumstances, all can adjust action force and release force within the specific limits.
To achieve these goals, the technical solution adopted in the utility model is: design a kind of butterfly spring with action force and release force Adjustment System-contact chip pressure device that continues.This Adjustment System is made up of action force adjusting device and release force adjusting device.The action force adjusting device is made up of the contact chip of adjusting screw, spring, push rod and band location hole.The release force adjusting device is made up of jacking block, adjustment screw and spring.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the butterfly spring of band action force and release force Adjustment System-the contact cross-sectional view of chip pressure switch.
As shown in Figure 1, the butterfly spring of this band action force and release force Adjustment System-contact the chip pressure switch to form by oil pocket seat 1, diaphragm 2, pushing block 3, butterfly spring 4, sealing ring 5, contact 6, action force and release force Adjustment System 8 and plastic housing 10; Action force and release force Adjustment System 8 are made up of action force adjusting device 12 and release force adjusting device 9.Action force adjusting device 12 is made up of the contact chip 15 of adjusting screw 11, spring 13, push rod 14 and band location hole.Release force adjusting device 9 is made up of jacking block 7, adjustment screw 11 and spring 13.
The installation of action force and release force Adjustment System:
Before installing, pressure switch earlier the action force adjusting device 12 of action force and release force Adjustment System 8 and the part of release force adjusting device 9 are mounted to assembly.To adjust screw 11, push rod 14 and spring 13 and dress up an assembly; Jacking block 7, adjustment screw 11 and spring 13 are dressed up an assembly.The screw hole that then this two assembly is passed plastic housing 10 bottom surfaces is respectively packed in the plastic housing, require the push rod 14 of action force adjusting device 12 will be positioned in the location hole of the contact chip 15 of being with location hole, rotation adjustment screw 11 coincides its bottom surface and plastic housing 10 bottom surfaces then.
The adjustment of action force and release force:
With the butterfly spring of band action force and release force Adjustment System 8-contact the chip pressure switch to be installed in (the standard scale precision is 0.25 grade) on the pressure gauge tester, test action power then and release force, then according to the difference of test value and standard value, screw 11 is adjusted in rotation respectively, and then test action power and release force, above repeatedly operation reaches requirement up to test value.Turn clockwise when adjusting screw 11, action force and release force are raise, otherwise reduce.The stroke adjusting range of adjusting screw 11 is ± 2mm, and the adjusting range of action force is 25%, and the adjusting range of release force is 15%.
Protection range of the present utility model not only is confined to the above, and the action force of the butterfly spring of this band action force and release force Adjustment System-contact chip pressure switch and the Adjustment System 8 used adjustment screws 11 of release force can adopt normal screws or adopt the screw of band spring base; Jacking block 7 can not adopt, and spring 13 is directly contacted with the contact chip 15 of band location hole; The metal embedded part of the also available band screw hole of the screw hole on the plastic housing.
The band action force that the utility model provides and the butterfly spring of release force Adjustment System-contact the chip pressure switch, action force and release force can be adjusted after the product encapsulation.This will improve the product precision greatly, reduce percent defective, boost productivity, and reduce cost.
