Abstract
Abstract A plug-in jumper for terminal blocks is provided for elastic engagement in openings in busbars and for electrical contact-making of the busbars of at least two junction and/or connecting terminals. The plug-in jumper includes a jumper bar having a bar strip and several plugs which are connected to the bar strip. Each plug has at least two contact legs located essentially parallel to one another, of which at least one is made elastic. The plug-in jumper makes it possible to electrically interconnect different busbars of different terminal blocks since the plugs have two contact areas which are located on top of one another for contact-making of two busbars of two junction and/or connecting terminals which are located next to one another, wherein the two busbars are located on a different planes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
180 words
A plug-in jumper for elastic engagement in openings in busbars and for electrical contact-making of busbars of at least two electrical junction and/or connecting terminals located side by side comprising: a jumper bar having a bar strip and at least two plugs projecting from the bar strip, each of the at least two plugs having at least two contact legs located essentially parallel to one another, at least one of the at least two contact legs being elastic, the contact legs being connected to form a plug that engages a respective busbar opening, the plugs including at least two contact areas located on top of one another for contact-making with said busbars of the two electrical junction and/or connecting terminals located side by side when the plugs are inserted into the openings of the busbars, said busbars being located on different planes from one another, and wherein the at least two contact areas include an upper contact area and a lower contact area, the width of the lower contact area being smaller than the width of the upper contact area.
Claim 2
Dependent Claim
180 words
A plug-in jumper for elastic engagement in openings in busbars and for electrical contact-making of busbars of at least two electrical junction and/or connecting terminals located side by side comprising: a jumper bar having a bar strip and at least two plugs projecting from the bar strip, each of the at least two plugs having at least two contact legs located essentially parallel to one another, at least one of the at least two contact legs being elastic, the contact legs being connected to form a plug that engages a respective busbar opening, the plugs including at least two contact areas located on top of one another for contact-making with said busbars of the two electrical junction and/or connecting terminals located side by side when the plugs are inserted into the openings of the busbars, said busbars being located on different planes from one another, and wherein the at least two contact areas include an upper contact area and a lower contact area, the width of the lower contact area being smaller than the width of the upper contact area.
Claim 3
Dependent Claim
21 words
The plug-in jumper of claim 1 , wherein the at least two plugs have widths that are different from one another.
Claim 4
Dependent Claim
38 words
The plug-in jumper of claim 1 , wherein spring forces of the plugs and contact legs are pointed parallel to a lengthwise direction of the bar strip upon insertion into the openings and upon contact-making with the busbars.
Claim 5
Dependent Claim
33 words
The plug-in jumper of claim 1 , wherein each plug has three contact legs arranged essentially parallel to one another, at least a middle contact leg of the three contact legs being elastic.
Claim 6
Dependent Claim

The plug-in jumper of claim 4 , wherein the middle contact leg is aligned offset from the other two contact legs.
Claim 7
Dependent Claim
22 words
The plug-in jumper of claim 1 , wherein at least one of the at least two contact legs includes a lengthwise slot.
Claim 8
Dependent Claim
16 words
The plug-in jumper of claim 4 , wherein the middle contact leg includes a lengthwise slot.
Claim 9
Dependent Claim
44 words
The plug-in jumper of claim 7 , wherein said middle contact leg includes an upper contact area and a lower contact area, the lengthwise slot extending from an area generally above the lower contact area to an area generally above the upper contact area.
Claim 10
Dependent Claim
