Abstract

An electrical terminal block arrangement includes a terminal block with at least one housing having a first insertion opening and a second insertion opening, and a clamping body including a contact metal, a first spring, and a second spring arranged inside the housing; a discharge resistor that includes a plug-in contact, the plug-in contact being plugged in through the first insertion opening of the housing; and a capacitor that includes at least one capacitor wire, the capacitor wire being inserted through the second insertion opening of the housing and being clamped and electrically contacted to the contact metal by the second spring. The plug-in contact of the discharge resistor is clamped and electrically contacted to the contact metal by the first spring.

First claim

The invention claimed is:

1. An electrical terminal block arrangement, comprising:
a terminal block comprising at least one housing having a first insertion opening and a second insertion opening, and a clamping body comprising a contact metal, a first spring, and a second spring arranged inside the housing;
a discharge resistor comprising a plug-in contact, the plug-in contact being plugged in through the first insertion opening of the housing; and
a capacitor comprising at least one capacitor wire, the capacitor wire being inserted through the second insertion opening of the housing and being clamped and electrically contacted to the contact metal by the second spring,
wherein the plug-in contact of the discharge resistor is clamped and electrically contacted to the contact metal by the first spring,
wherein the housing has a third insertion opening and the clamping body has a third spring,
wherein the first spring, the second spring, and the third spring each have a fastening spring leg and each have a clamping spring leg, and
wherein the housing has a first pusher configured to pivot the clamping spring leg of the first spring, the first pusher being mounted so as to be movable between an open position and a closed position.

2. The arrangement according to claim 1 , wherein the housing has a second pusher configured to pivot the clamping spring leg of the third spring, the second pusher being mounted so as to be movable between an open position and a closed position.

3. The arrangement according to claim 2 , wherein at least one of the first pusher rests against the clamping spring leg of the first spring, or the second pusher rests against the clamping spring leg of the third spring such that the spring force exerted by the respective clamping spring legs is configured to move at least one of the first pusher or the second pusher into the closed position.

4. The arrangement according to claim 1 , wherein the housing has an actuating element configured to pivot the clamping spring leg of the third spring, the actuating element being mounted so as to be pivoted between an open position and a closed position.

5. The arrangement according to claim 1 , wherein the terminal block comprises a plurality of housings each having a first insertion opening, a second insertion opening, and a third insertion opening and each having a clamping body, the respective housings being arranged next to one another.

6. The arrangement according to claim 5 , wherein the discharge resistor has a plurality of plug-in contacts when there is a plurality of housings arranged next to one another, each plug-in contact being plugged into the first insertion opening of a corresponding housing and being clamped and electrically contacted to the corresponding contact metal by the first spring.

7. A method of plugging a terminal block onto a capacitor as a capacitor connection, the terminal block comprising:
at least one housing having a first insertion opening and a second insertion opening, and a clamping body comprising a contact metal, a first spring, and a second spring arranged inside the housing;
a plug-in contact of a discharge resistor being plugged in through the first insertion opening of the housing and being clamped and electrically contacted to the contact metal by the first spring,
the method comprising:
plugging the terminal block onto the capacitor, the capacitor comprising at least one capacitor wire, the capacitor wire being inserted through the second insertion opening of the housing and being clamped and electrically contacted to the contact metal by the second spring,
wherein the housing has a third insertion opening and the clamping body has a third spring,
wherein the first spring, the second spring, and the third spring each have a fastening spring leg and each have a clamping spring leg, and
wherein the housing has a first pusher configured to pivot the clamping spring leg of the first spring, the first pusher being mounted so as to be movable between an open position and a closed position.

8. An electrical terminal block arrangement, comprising:
a terminal block comprising at least one housing having a first insertion opening and a second insertion opening, and a clamping body comprising a contact metal, a first spring, and a second spring arranged inside the housing;
a discharge resistor comprising a plug-in contact, the plug-in contact being plugged in through the first insertion opening of the housing; and
a capacitor comprising at least one capacitor wire, the capacitor wire being inserted through the second insertion opening of the housing and being clamped and electrically contacted to the contact metal by the second spring,
wherein the plug-in contact of the discharge resistor is clamped and electrically contacted to the contact metal by the first spring,
wherein the housing has a third insertion opening and the clamping body has a third spring,
wherein the first spring, the second spring, and the third spring each have a fastening spring leg and each have a clamping spring leg, and
wherein the housing has an actuating element configured to pivot the clamping spring leg of the third spring, the actuating element being mounted so as to be pivoted between an open position and a closed position.
