Abstract
The utility model relates to a jumping diaphragm pressure control switch. The original speed for closing and opening of a contact is slower, and is easy to generate larger spark and electric arc which can ablate the contact, thus influencing the service life of the pressure control switch. The jumping diaphragm pressure control switch comprises a pressure switch shell (1) and an upper cover (2), wherein the pressure switch shell is internally provided with a fixed seat (3) with an arc contact surface, the fixed seat is provided with an adjusting terminal (4) and a switching plate (5), and the pressure switch shell is provided with a group of jumping diaphragms (8). The product can be widely used for pressure control on systems such as aviation, aerospace, chemical industry, shipping, industrial automation and the like.
Description
Technical field:
The utility model relates to a kind of switch, is specifically related to a kind of flick diaphragm formula pressure control switch.
Background technology:
Development both at home and abroad at present and the mechanical compression control switch of producing are respectively flat diaphragm formula, Convoluted diaphragm-type, bellows-type, bellows-type and rubber pattern.Wherein bellows-type and bellows-type volume are big, though the pressure control switch of rubber membrane type can be made smaller volume, departure is big, hard to bear low and higher temperature.Flat diaphragm formula and Convoluted diaphragm-type pressure control switch are easily made smaller volume, but it is slower that the closure of contact disconnects, be easy to generate bigger spark and electric arc, the ablation contact, and then influence the working life of pressure switch, and when force value changed near specified starting pressure value, the closed phenomenon that disconnects can appear repeatedly in the contact.
Summary of the invention:
The purpose of this utility model provides a kind of flick diaphragm formula pressure control switch; can effectively prevent the misoperation of pressure control switch; novel cabling mode and the spacing overcurrent protection structure of arc surface applying is provided; prolong the working life of diaphragm and contact, increased the reliability of pressure control switch.
Above-mentioned purpose realizes by following technical scheme:
Flick diaphragm formula pressure control switch, its composition comprises: pressure switch housing and loam cake, holder with arc contact surface is installed in the described pressure switch housing, is installed on the described holder and adjust terminal and keyset, one group of flick diaphragm is installed on the described pressure switch housing.
Described flick diaphragm formula pressure switch, described adjustment terminal comprises ceramic ring, described pressure switch housing comprises gasket ring, on the described flick diaphragm bottom electrode is installed, the copper cash of described bottom electrode passes the centre bore of described adjustment terminal, and draw lead in copper cash upper end and be connected to described keyset, electrode is installed in described adjustment terminal lower end, and the side opening that lead passes described adjustment terminal of drawing of described top electrode connects described keyset.
Comprise air inlet or inlet opening below the described flick diaphragm formula pressure switch, described pressure switch housing.
The beneficial effects of the utility model:
1. the utility model replaces traditional flat diaphragm with flick diaphragm.When force value reaches the kick critical point of (surpassing) flick diaphragm, flick diaphragm produces kick, instantaneous Closing Switch; When force value falls rebound critical point to (being lower than) flick diaphragm after rise, flick diaphragm produces resilience, instantaneous cut-off switch, therefore can significantly reduce the generation of spark and electric arc, and avoided the closure of other diaphragm contact and open slowly and near the starting pressure value the closed repeatedly phenomenon that disconnects, can improve the working life of contact greatly thus.
2. the flick diaphragm of the utility model use can be avoided the phenomenon of flat diaphragm diaphragm generation chatter when being subjected to vibratory impulse, prevents the misoperation of pressure control switch.
3. the utility model obtains different ranges by adopting the mode of multilayer flick diaphragm stack, can realize the seriation of product.
4. the distortion of generation that arc surface applying position limiting structure of the present utility model can be protected flick diaphragm to greatest extent because transship; when flick diaphragm is subjected to overload pressure; the arc surface of diaphragm deformation and holder lower end is fitted; reach spacing purpose; the reliability of great increase pressure control switch, the working life that has prolonged diaphragm.
5. the lead-in wire mode that the utility model adopted, the copper cash that is connected with bottom electrode are passed and are adjusted the terminal centre bore, are connected to keyset from copper cash top lead-in wire again; The lead-in wire of top electrode passes the side opening of adjusting terminal, is connected to keyset.Avoid the traditional approach that goes between between two electrodes up and down, guaranteed the realization on the arc surface applying position limiting structure space.
