Description

Electrical terminal block

The invention relates to an arrangement with a terminal block, a discharge resistor and a capacitor.

In the field of electrical engineering, capacitors are used, inter alia, for the compensation of reactive power.

Such capacitors generally have a connection block which can be plugged onto the capacitor.

Such a connection block for attachment to a capacitor usually comprises a housing with an electrical unit disposed within the housing

Current bar, the housing has an opening to the

Implementation and electrical contacting of a

Capacitor wire with the current bar and an opening for receiving and electrical contacting of an electrical conductor with the current bar has. Furthermore, some terminal blocks have a further housing opening for receiving and electrical contacting of a

Discharge resistance with the current bar on.

Discharge resistance are introduced through the respective opening in the housing and electrically connected via screw terminals with the current bar.

However, screw terminals have the disadvantage that it is not apparent from the outside, whether the screw of

Screw terminal tightened and thus the electrical Conductor or the electrical resistance fixed to the

Current bar is jammed. Furthermore, the screw of the screw terminal is tightened with a defined torque, so on the one hand a minimum clamping force is achieved to clamp the inserted into the screw terminal electrical conductor or the discharge resistor fixed to the current bar, and on the other hand, too no torque is applied, which the

Could damage the screw terminal.

In addition, the screws of the screw terminal can be affected by the influence of temperature changes and

Shake the vibrations over time, so that the

Clamping effect of the screw terminal decreases and the electrical contacting of the electrical conductor with the current bar or the electrical contact of the

Discharge resistance is interrupted with the current bar.

It is the object of the invention to provide an arrangement with a terminal block, a discharge resistor and a capacitor, wherein the discharge resistor is simply and safely electrically contacted with the terminal block.

In principle, the first spring, the second spring and the third spring can be designed differently. A preferred development of the invention, however, provides that the first spring, the second spring and the third spring each have a fastening spring leg and in each case a clamping spring leg. The respective

Befestigungsfederschenkel serves to fix the position of the respective spring on the contact metal, wherein the respective clamping spring legs of a jamming of the electrical

Contacting a discharge resistor 70, not shown, with the clamping body 30, a second insertion opening 22 for receiving and electrical contacting of a capacitor wire 60, not shown, of a capacitor the clamping body 30 and a third insertion opening 23 for receiving and electrical contacting a not

shown stripped conductor end of an electrical conductor with the clamping body 30. Furthermore, the housing 20 comprises a first receiving region 24 for receiving a displaceably mounted first pusher 40 and a second receiving region 25 for receiving a displaceably mounted second pusher 50. The clamping body 30 comprises a contact metal 34, a plugged onto the contact metal 34 first spring 31 for electrical Contacting the discharge resistor 70 with the contact metal 34, one on the contact metal 34th

plugged second spring 32 for electrically contacting the capacitor wire 60 with the contact metal 34 and a plugged onto the contact metal 34 third spring 33 for electrically contacting the stripped end of the electrical conductor with the contact metal 34. As can be seen from Figure 2, the first spring 31, the second spring 32 and the third spring 33 each one

Fixing spring legs 311, 321, 331 and each have a clamping spring legs 312, 322, 332 on. The respective

Befestigungsfederschenkel 311, 321, 331 serves the

Fixing the position of the respective spring 31, 32, 33 am

Contact metal 34, wherein the respective clamping spring leg 312, 322, 332 serves to jam the electrical conductor or the discharge resistor or the capacitor wire with the contact metal 34.

The springs 31, 32, 33 are arranged relative to the contact metal 34 such that in each case the clamping spring leg 312 of the first spring 31 exerts a first spring force on the contact metal 34, the clamping spring leg 322 of the second spring 32 exerts a second spring force on the contact metal 34 and the clamping spring leg 332 of the third spring 33 exerts a third spring force on the contact metal 34. In this way, the respective clamping spring legs 312, 322, 332 of the first spring 31, the second spring 32 and the third spring causes

33 independently of each other, a spring force to

Jamming of the electrical conductor or the

Discharge resistor or the capacitor wire with the

Contact metal 34.

3 shows a section through the housing 20 of the terminal block 10 with the inside of the housing 20th

arranged clamping body 30. The clamping body 30 is arranged substantially centrally within the housing 20. Furthermore, it can be seen from this section that the

Springs 31, 32, 33 to each other on the contact metal

34 are attached, that the direction of the clamping force of the first spring 31 is substantially perpendicular to the direction of the clamping force of the second spring 32 and the direction of the second clamping force of the second spring 32 substantially perpendicular to the direction of the clamping force of the third spring 33. In this way can the electrical conductor, the

Capacitor wire 60 and the discharge resistor 70 are respectively inserted from different insertion directions in the housing 20 and electrically connected to the clamping body 30

be contacted.

It is provided that the electrical conductor is inserted through the third insertion opening 23 in the housing 20 and clamped on the clamping spring leg 332 of the third spring 33 with the contact metal 34. Above the third insertion opening 23 is the second receiving area 25 with the second pusher 50 displaceably mounted therein

arranged. The second pusher 50 is within the second Receiving portion 25 slidably mounted between a closed position and an open position. Furthermore, the second pusher 50 includes an inner end 51 and an outer end 52, the inner end 51 on the

Clamping spring leg 332 of the third spring 33 abuts and the force exerted by the clamping spring leg 332 spring force the second pusher 50 moves into the closed position.

In this way, the second pusher 50 rests in the

Closed position, so that it can be seen from the outside that the clamping spring leg 332 is biased and thus a

Spring force on the contact metal 34, or on the jammed with the contact metal 34 electrical conductor exerts. Only by the active displacement of the second pusher 50 from the closed position to the open position of the clamping spring leg 332 is pivoted such that the

Deadlock of the clamped electrical conductor is released. The third spring 33 is moved by the displacement of the second pusher 50 from the closed position in the

Opening position biased further, so that the

Clamping spring leg 332 strives to return to the starting position and thus to move the second pusher 50 again from the open position to the closed position. Analogous to the principle of jamming of the electrical

Conductor on the third spring 33 with the contact metal 34 and the plug contact 71 of the discharge resistor 70 via the first spring 31 is clamped to the contact metal 34. The plug contact 71 of the discharge resistor 70 is inserted in the first insertion opening 21 and over the

Clamping spring leg 312 of the first spring 31 with the

Contact metal 34 jammed. Above the first

Insertion port 21 is the first pusher 40 in the first Pick-up area 24 inserted and slidably mounted between the open position and the closed position. The first pusher 40 has an inner end 41 and an outer end 42, with the inner end 41 abutting the clamping spring leg 312 of the first spring 31. By moving the first pusher 40 from the

Closing position in the opening position is the

Clamping spring leg 312 pivoted so that the

Discharge resistor 70 can be unplugged from the terminal block. Likewise, by moving the second pusher 50 from the closed position to the open position, the first spring 31 is further biased, so that the

Clamping spring leg 312 endeavors to return to the starting position and thus to move the second pusher 50 again from the open position to the closed position.

The jamming and the contacting of the capacitor wire 60 via the second spring 32 with the contact metal 34 is analogous to the contacting of the electrical

Conductor via the third spring 33 with the contact metal 34 or the contacting of the discharge resistor 70 via the first spring 31 with the contact metal 34. However, in contrast to the electrical conductor and the

Discharge resistor 70 of the capacitor wire 60 undetachably jammed on the second spring 32 with the contact metal 34. In addition, the annular gap between the capacitor wire 60 and the second insertion opening 22 is soldered gas-tight.

In Figure 4, the known from Figure 1 terminal block 10 with a pivotally mounted actuating element 90 can be seen. The actuator 90 has a

Handle portion 901 with a recess 902, a

Receiving portion 903 with an opening 904 and a

Unlocking portion 905 with a stop 906 on. For receiving the pivotally mounted

Actuator 90, a bearing pin 26 is arranged on the housing 20, which engages in the opening 904 on the receiving portion 903 of the actuating element 90 and represents the pivot axis of the actuating element 90. Furthermore, a stamp 27 is arranged with a labeling surface on the housing 20, wherein the punch 27 engages in the recess 902 of the actuating element 90 and in the closed position of the actuating element 90, the labeling surface covered by the handle portion 901 and the opening surface of the actuating element 90 releases the labeling surface. In this way, the locking state of the

Actuator 90 visible from the outside.

On the contact metal 34 of the clamp body 30, the first spring 31, the second spring 32 and the third spring 33 are arranged. The mounting leg 331 of the third spring

33 comprises two retaining spring legs 335, each with a projection 333 for latching with the contact metal

34 arranged rear detents 334th

Starting from the closed position of the actuating element 90, the actuating element 90 is pivoted to the opening position for insertion of a conductor end, not shown, into the third insertion opening 23. For this purpose, the unlocking section 905 engages the retaining spring legs 335 of the fastening spring leg 331 and displaces the projections 333 from the rear catch 334. In this way, the clamping spring leg 332 is pivoted in such a way that the conductor end to be inserted into the contact area

can be introduced. In addition, in the opening position of the actuating element 90, the labeling surface of the punch 27 is released, so that it can be seen from the outside that the third spring 33 exerts no spring force on the contact metal 34 and the conductor end can be inserted into the third insertion opening 23. For jamming the conductor end, not shown, between the contact metal 34 and the clamping spring leg 332, the pivotally mounted actuating element 90 is pivoted from the open position to the closed position. Due to the pivoting movement of the actuating element 90, the third spring 33 is pivoted such that the at

Holding spring legs 335 arranged projections 333 slide into the arranged on the contact metal 34 rear catches 334. By the pivoting practice of

Clamping spring legs 332 of the third spring exert a spring force on the contact metal 34 to jam and contact the conductor end between the clamping spring leg 332 and the contact metal 34. Likewise by the

Pivoting movement of the actuating element 90 arranged on the stamp 27 labeling surface through the

Covered portion 901 of the actuating element 90.

Thus, it can be seen from the outside that the actuating element 90 rests in the closed position and the third spring 33 exerts a spring force on the contact metal 34. In Figure 5 is a section through the housing 20 of the

Clamping blocks 10 shown. The clamping block 10 shown in FIG. 5 differs from that shown in FIG

Clamping block 10 to the effect that the clamping spring leg 332 of the third spring 33 via the pivotally mounted

Actuator 90 is actuated. In this way, introduced by the third insertion opening 23 stripped conductor end of an electrical conductor via a pivoting movement of the actuating element 90 between the clamping spring leg 332 of the third spring 33 and the Contact metal 34 self-adjusting clamped and

be contacted electrically.

Furthermore, it can be seen that the plug contact 71 of the Entladewiederstands 70 is inserted into the first insertion opening 21 of the housing 20 and clamped on the clamping spring leg 312 of the first spring 31 with the contact metal 34 and electrically contacted. The first pusher 40 is in a direction perpendicular to the insertion of the

Plug contacts 71 slidably mounted in the first receiving portion 24 of the housing 20. By a shift of the first Puschers 40 from the closed position in the

Opening position is between the contact metal 34 and the clamping spring leg 312 jammed plug contact 71 solvable and the discharge resistor 70 interchangeable.

As can be seen from FIG. 6, the clamping block 10 has a plurality of housings 20 arranged side by side in a base element 80. The housing 20 are latched to the base member 80 so that they have a fixed

Form unity. Furthermore, it can be seen that the

each housing 20 each having a third insertion opening 23 for insertion of an electrical conductor and in each case a corresponding second pusher 50.

Furthermore, it can be seen from FIG. 6 that the

Discharge resistor 70 and the first pusher 40 for the

Plurality of juxtaposed housing 20th

is trained. In this way, by the operation of the first pusher 40 for the majority of

side by side formed housing 20 designed and trained discharge resistor 70 are unplugged from the terminal block. Reference sign
