Abstract
The moving contact mechanism of electromagnetic relay comprises moving contact, moving contact spring leaf and conducting wire, in which the front end of moving contact spring leaf is equipped with conducting sheet, the moving contact also is placed on the front end of moving contact spring leaf, and formed into electric contact with conducting sheet, its conducting wire is connected on the conducting sheet, and the tail end of moving contact spring leaf is equipped with insulating gasket, and its moving contact and moving contact leading pin are formed into electric connection by means of conducting sheet and conducting wire. It is used in electromagnetic relay, and can miniaturized high-power electromagnetic relay and can reduce energy consumption.
Description
The present invention relates to the dynamic contact mechanism of electromagnetic relay in the low-voltage electrical apparatus.
Existing dynamic contact mechanism for electromagnetic relay, constitute by moving contact, moving contact reed, lead, moving contact is arranged on the front end of moving contact reed, lead is connected the end of moving contact reed, when electromagnetic relay is worked, electric current is to pass through moving contact, moving contact reed, lead to the moving contact leading foot, and like this, electric current must pass through the moving contact reed.Adopt the electromagnetic relay of this dynamic contact mechanism, 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 dynamic contact mechanism for electromagnetic relay 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 dynamic contact mechanism 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 dynamic contact mechanism for electromagnetic relay is applicable to more powerful electromagnetic relay in order to make it, is provided with two leads, is connected to the both sides of conducting strip.
Aforesaid dynamic contact mechanism for electromagnetic relay, 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 dynamic contact mechanism for electromagnetic relay, 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 the innovation of a high-power magnetic relay miniaturization, 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.
Dynamic contact mechanism for electromagnetic relay shown in Fig. 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, and 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.Entire mechanism can be fixed on the support of electromagnetic relay magnetic system via armature.
Dynamic contact mechanism for electromagnetic relay shown in Fig. 1～3, lead 3 can be single, and it is connected a side of conducting strip 3, for a little bit smaller electromagnetic relay of power, just this is applicable.Insulation pressing 6 also can, and directly moving contact reed 7 is fixed on the insulation spacer 5.
Claims (3)
1, a kind of dynamic contact mechanism for electromagnetic relay, comprise moving contact, moving contact reed, lead, it is characterized in that: the 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.
