Abstract
The present invention relates to a movable contact mechanism for an electromagnetic relay, which comprises a movable contact, a movable contact reed and a conducting wire, wherein the front end of the movable contact reed is provided with a conductive sheet, the movable contact is also arranged at the front end of the movable contact reed and forms electrical contact with the conductive sheet, and the conducting wire is connected to the conductive sheet; the end of the movable contact reed is provided with an insulating spacer, and the movable contact is electrically connected with the leading-out pin of the movable contact by the conductive sheet and the conducting wire. The present invention is applied to the electromagnetic relay, and thus, the electromagnetic relay with high power has the advantages of miniaturization and low energy consumption.
Description
The present invention relates to the moving contact structure of electromagnetic relay in the low-voltage electrical apparatus.
Existing electromagnetic relay moving contact structure, by moving contact, moving contact reed, lead constitutes, moving contact is arranged on the front end of moving contact reed, lead is connected the end of moving contact reed, and when electromagnetic relay was worked, electric current was to the moving contact leading foot through moving contact, moving contact reed, lead, like this, electric current must pass through the moving contact reed.Adopt the electromagnetic relay of this moving contact structure, particularly powerful electromagnetic relay, the big electric current flow path moving contact reed that 10A is above can make the heating of moving contact reed and follows the string, and causes the electromagnetic relay action malfunctioning.In order to address this problem, take to thicken or widen the method for moving contact reed usually, and the shortcoming of doing like this is the coil power dissipation of electromagnetic relay will increase, the volume of magnetic system also will increase.
The objective of the invention is to solve the problems referred to above that prior art exists, a kind of electromagnetic relay moving contact structure that can be operated under the big electric current and don't can increase coil power dissipation and magnetic system volume is provided.
The objective of the invention is to realize by following technical proposals.A kind of moving contact structure of electromagnetic relay, comprise moving contact, moving contact reed, lead, front end at the moving contact reed is provided with conducting strip, moving contact also is arranged on the front end of moving contact reed and electrically contacts with conducting strip formation, lead is connected a side of conducting strip, is provided with insulation spacer at the end of moving contact reed.Like this, the end and the insulation spacer of moving contact reed can be fixed, the armature of insulation spacer and electromagnetic relay is fixed, armature then is fixed on the support of magnetic system, when electromagnetic relay is worked, electric current then be through moving contact, conducting strip, lead to the moving contact leading foot, and the moving contact reed of not flowing through.
Aforesaid electromagnetic relay moving contact structure, in order to reinforce moving contact reed terminal position, also in order better moving contact reed and other member to be insulated, insulation pressing is set above insulation spacer simultaneously, this insulation pressing and insulation spacer are clamped the moving contact reed.
The present invention is owing to the front end at the moving contact reed is provided with conducting strip, end at the moving contact reed is provided with insulation spacer and insulation pressing, lead can be connected on the conducting strip and directly moving contact, conducting strip be formed with the moving contact leading foot and be electrically connected, more existing electromagnetic relay moving contact structure, under the situation of high-power or big electric current, just there is no need thickening or widen the moving contact reed, therefore also just can not increase electromagnetic relay coil power consumption and magnetic system volume.It is applied to electromagnetic relay, can bring a high-power magnetic relay miniaturization, the innovation of low energy consumption.
Introduce embodiments of the invention below by accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is Fig. 1 upward view.
Fig. 3 is Fig. 1 vertical view.
Electromagnetic relay moving contact structure as Figure 1-3, comprise: moving contact 2, moving contact reed 7, lead 3, conducting strip 1 is arranged on the front end of moving contact reed 7, moving contact 2 also is arranged on the front end of moving contact reed 7 and electrically contacts with conducting strip 1 formation, lead 3 is two both sides that are connected to conducting strip 1, insulation spacer 5 is arranged on the terminal of moving contact reed 7 with insulation pressing 6 and moving contact reed 7 is clipped in the middle, among the figure, insulation spacer 5 is also clamped the both sides that are fixed on moving contact reed 7 with lead 3 simultaneously with insulation pressing 6; The 4th, armature, usually, armature 4 is fixed together with insulation spacer 5.Total can be fixed on the support of electromagnetic relay magnetic system via armature.
Electromagnetic relay moving contact structure as Figure 1-3, lead 3 can be single, and it is connected a side of conducting strip 3, and for a little bit smaller electromagnetic relay of power, this is just applicable.Insulation pressing 6 also can, and directly moving contact reed 7 is fixed on the insulation spacer 5.
