Description
Technical Field
The utility model relates to an electric contact field, specific mosaic electric contact for electric contact pressure gauge that says so.
Background
Pressure is an extremely important thermal parameter in modern industrial production, and accurate measurement and control of pressure is an important task for ensuring that the production process can run safely and well according to a plan. The electric contact pressure gauge is formed by additionally installing an electric contact switch comprising a movable contact and a fixed contact on a spring tube pressure gauge, and the switch contact can be connected or disconnected when a pressure gauge pointer rotates to a preset pressure value position of the fixed contact except for indicating the pressure. If the pointer reading exceeds or falls below a set pressure value, an alarm is triggered, which is a so-called "alarm contact". Electro-contact pressure gauges may also be used for start, stop or switch-over processes.
The traditional electric contact electric device contact adopts a common cylindrical contact for contact, after the electric contact pressure gauge is used for a period of time, an electric contact moving contact and a static contact of the electric contact pressure gauge are ablated due to electric arc, so that the contact surface of the electric contact pressure gauge is rough and carbonized, electric arc is generated between the contacts of the electric contact, the contacts are ablated and even sintered together, and finally the electric contact pressure gauge is damaged and fails. Therefore, a mosaic type electric contact for an electric contact pressure gauge is proposed to solve the above problems.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-2, the embedded electrical contact for an electrical contact pressure gauge of the present invention includes a static contact groove 1, a static contact 2, a moving contact 3, a metal fixing block 4, a return spring 5 and a support rod 6; a static contact groove 1 is formed in the middle of the static contact 2; a metal fixing block 4 is fixed on the moving contact 3; a support rod 6 is arranged on the metal fixing block 4, and a return spring 5 is sleeved on the outer side wall of the support rod 6; the diameter of the moving contact 3 is equal to that of the semicircular groove of the fixed contact groove 1.
As a technical optimization scheme of the utility model, static contact 2 and moving contact 3 are the columnar structure.
As a technical optimization scheme of the utility model, the tank bottom of static contact recess 1 and the axis coincidence of static contact 2 make the area of intimate contact increase between static contact 2 and the moving contact 3, eliminate the electric discharge arc phenomenon that the electric contact leads to because of the contact is not good.
As a technical optimization scheme of the utility model, static contact 2 and moving contact 3 mutually perpendicular.
As a technical optimization scheme of the utility model, the tank bottom of static contact recess 1 equals with the area of moving contact 3 contact, makes contact better between tank bottom and the moving contact 3 of static contact recess 1 when the contact.
The utility model provides a pair of an embedded electric contact's for electric contact pressure gauge theory of operation as follows:
when the device works, the static contact 2 and the moving contact 3 are in a separated state, and when the pressure measured by the electric contact pressure gauge reaches a set upper limit or lower limit, the support rod 6 is subjected to the pressure transmitted by the measuring system, so that the metal fixed block 4 and the moving contact 3 are extruded. Then, the moving contact 3 is close to the static contact 2, the moving contact 3 is communicated with the static contact groove 1, and the current passes through and is transmitted to an indicating system of an electric contact pressure gauge. When the pressure transmitted from the measuring system of the electric contact pressure gauge is relieved, the reset spring 5 can pull the support rod 6 to reset, and further, the support rod 6 can pull the metal fixing block 4 and the moving contact 3, so that the fixed contact groove 1 and the moving contact 3 are separated, and the current is disconnected.
