Abstract

A plug-in type busbar for connecting with a relay or a breaker includes an insulating housing and a plurality of conductive busbar parts insulated from each other in the insulating housing. Two interface sets are provided on two ends of the busbar respectively. One interface set on one end of one busbar can be inserted in the other interface set of the other bus bar. The busbar is connectable with adjacent busbars through the interface sets at both ends thereof. At least an electrical connection is formed between the adjacent two busbars after the adjacent two busbars are inserted each other. When a longer busbar is demanded, an extended structure can be obtained by simply connecting two busbars together, and a connection of the busbars can be completed by connecting the insulating housing in a plugged manner.

First claim

The invention claimed is:

1. A plug-in type busbar comprising:
an insulating housing; a plurality of busbar parts made of conductive materials, disposed inside said insulating housing and insulated from each other; wherein, each of said busbar parts comprises a connector base and a plurality of connectors which are integrally formed on one side of said connector base and extend out of said insulating housing for being electrically connectable in the form of a connector set to an electrical appliance, and the connector set is formed by adjacently arranged connectors respectively connecting with an individual connector base; said busbar, comprising a first end and a second end, is provided with two pluggable interface sets respectively disposed at each end, the interface set at the first end is provided with a structure that is adapted for being connected with the interface set at the second end in a plugged manner, said busbar is connectable with another two said busbars through the interface sets at both ends thereof; an electrical connection is formed between two connector sets of two adjacent busbars after busbars are connected together; wherein, said connector set comprises a first connector set disposed close to the interface set at the first end, a second connector set disposed closed to the interface set at the second end, and an intermediate connector set disposed on the middle segment of said connector base; the connectors of said first connector set are spaced apart from each other in the longitudinal direction of said busbar; the connectors of said second connector set have the corresponding arrangement to that of the connectors of said first connector set, and each two adjacent connectors of said first connector set and said second connector set formed on the same connector base are spaced apart with each other in the direction of thickness of the connector; after two said busbars are connected together by one busbar being plugged in another, each connector of said first connector set on one busbar part is only connected in an overlapped manner with a connector of said second connector set of a corresponding busbar part of an adjacent busbar, and in the direction that two connectors approach to each other, the difference between the deviation of one connector and that of the other connector is equal to the thickness of a corresponding connector.

2. The busbar of claim 1 , wherein,
after two busbar are connected together, the tops of connectors of said first connector set and that of corresponding connectors of said second connector set on the connector base are in contact with each other.

3. The busbar of claim 2 , wherein,
said connector base comprises a flat segment and a staggered segment, said first connector set is formed on said staggered segment, said second connector set and said intermediate connector sets are formed on said flat segment; and each two connector bases are electrically insulated with each other, after connected together in an overlapped manner.

4. The busbar of claim 3 , wherein,
each of said connectors is perpendicular to said connector base; the difference between the distance that each connector of said first connector set deviates from said connector base and the distance that each corresponding connector of said second connector set deviates from said connector base is equal to the thickness of said connector.

5. The busbar of claim 4 , wherein,
step-shaped ends of said busbar are formed after busbar parts are arranged in an overlapped manner, and the two interface sets disposed at two ends of the insulating housing are respectively provided with a step-shaped connecting structures.

6. The busbar of claim 5 , wherein,
the end portions of said step-shaped connecting structures have tongues and grooves formed thereon.

7. The busbar of claim 6 , wherein,
each of said tongues is dovetail shaped; and each of said grooves is also dovetail shaped, adapted for allowing a corresponding tongue to be plugged in.

8. The busbar of claim 7 , wherein,
said busbar comprises a first busbar part, a second busbar part and a third busbar part;
said interface set at the first end of said busbar comprises three tongues, which comprise a first tongue, a second tongue and a third tongue, all of which projects towards an adjacent busbar after two said busbars are connected together; and
said interface set further comprises
a first groove, located between said first tongue and said second tongue;
a second groove, located between said second tongue and said third tongue; and
a third groove, located on one side of said first tongue far away from said second groove;
said first tongue is adapted for being plugged in said second groove in an engaged manner, said second tongue is adapted for being plugged in said first groove in an engaged manner, and said third tongue is adapted for being plugged in said third groove in an engaged manner;
said interface set at the second end of said busbar comprises four tongues, in which a fourth tongue projecting towards an adjacent busbar after two busbars are connected together is arranged on one side of said first tongue close to said third groove, and said third groove is located between said fourth tongue and said first tongue.

9. The busbar of claim 7 , wherein,
said busbar comprises a first busbar part, a second busbar part, a third busbar part and a fourth busbar part;
said first interface set at the first end of said busbar comprises four tongues, which comprise a first tongue, a second tongue, a third tongue and a fourth tongue, all of which projects towards an adjacent busbar after two said busbars are connected together; and
said first interface set further comprises
a first groove, located between said first tongue and said second tongue;
a second groove, located between said second tongue and said third tongue;
a third groove, located between said third tongue and said fourth tongue;
a fourth groove, located on one side of said first tongue far away from said second groove;
said first tongue is adapted for being plugged in said third groove in an engaged manner, said second tongue is adapted for being plugged in said second groove in an engaged manner, said third tongue is adapted for being plugged in said first groove in an engaged manner, and said fourth tongue is adapted for being plugged in said fourth groove in an engaged manner;
said interface set at the second end of said busbar comprises five tongues, in which a fifth tongue projecting towards an adjacent busbar after two busbars are connected together is arranged on one side of said first tongue close to said fourth groove, and said fourth groove is located between said fifth tongue and said first tongue.

10. The busbar of claim 7 , wherein,
said busbar comprises a first busbar part and a second busbar part;
said interface set at the first end of said busbar comprises two tongues, which comprises a first tongue and a second tongue, both of which projects towards an adjacent busbar after two said busbars are connected together; and
