Connecting copper bar 5 and line nose 8 are fixed on connecting end surface 9 with the cooperation of bolt 7, connecting hole has fixed connecting hole after being screwed into
With the threaded hole of bolt cooperation.
It is understood that if it is the structure in present embodiment, then connecting copper bar 5 and line nose 8 be also required for
The fixation hole that wire connecting portion 3 matches, so that connecting copper bar 5 is fixed on connecting end surface 9 after bolt 7 is screwed into.It was taking out stitches
Cheng Zhong, it is only necessary to dismantle wire connecting portion 3, without operating fixed part 4, wire connecting portion 3 is dismantled, then line nose 8 and connecting end surface 9
It is separated with connecting copper bar 5；During the installation process, it is only necessary to the fixation hole of line nose 8 is directed at the connecting hole on connecting end surface 9,
Bolt 7 is screwed into again.The structure of other parts refers to description above, and this embodiment is not repeated.
Be preferably carried out mode as another, wire connecting portion 3 is specially the swivel nut being arranged on connecting end surface 9, with bolt 7
Connecting copper bar 5 and line nose 8 are fixed on connecting end surface 9 by cooperation.
In specific implementation, can be by a part of swivel nut in connecting end surface 9 for the fastness of swivel nut, one
Divide protrusion connecting end surface 9, i.e. swivel nut can be mounted on connecting end surface 9 by the way of being embedded in.It is understood that if it is
Structure in present embodiment, then connecting copper bar 5 and line nose 8 are also required for the fixation hole matched with wire connecting portion 3, thus
Connecting copper bar 5 and line nose 8 are fixed on connecting end surface 9 by bolt 7 after being screwed into.During taking out stitches, it is only necessary to by wire connecting portion 3
It dismantles, without operating fixed part 4, wire connecting portion 3 is dismantled, then line nose 8 is separated with connecting end surface 9 and connecting copper bar 5；Pacifying
During dress, it is only necessary to be screwed by the connecting hole on the fixation hole alignment connecting end surface 9 of line nose 8, then by bolt 7.Its
The structure of its part refers to description above, and this embodiment is not repeated.
It is described in detail above for the structure of junction block, in addition to junction block described above, the present invention is also
A kind of termination comprising the junction block is provided.The termination, including connecting copper bar 5, to the line nose 8 of external connection with
And junction block described in above-described embodiment, wherein connecting copper bar 5 have wire connecting portion and fixed part respectively with the wiring on junction block
Portion 3 and fixed part 4 match.
Due to the embodiment hereinbefore detailed description of junction block, in the present embodiment, no longer to it
It repeats.
Termination provided in this embodiment includes junction block, and the junction block is for connecting connecting copper bar and using external connection
Line nose, including junction block ontology is provided on the connecting end surface of junction block ontology and to connect for connecting copper bar with line nose
Wire connecting portion is at least one with the fixed part for being fixedly connected with copper bar and connecting end surface, fixed part.Due to wire connecting portion and fixation
Portion be it is separated, fixed part is for being fixedly connected with copper bar and connecting end surface, and wire connecting portion is for being fixedly connected with copper bar, line nose and company
Contact surface, therefore, when taking out stitches, it is only necessary to wire connecting portion is dismantled, so that line nose is separated with connecting end surface and connecting copper bar, and by
In the presence of fixed part, the relative position of connecting copper bar and connecting end surface is constant；During wiring, it is only necessary to pass through wire connecting portion
Line nose is connect with connecting copper bar, to be fixed on connecting end surface.In conclusion the junction block solves single hole junction block appearance
Copper bar is easily caused to loosen, the bad situation of crimping face contact is effectively reduced the generation of secondary failure.Further, since fixed
Portion plays the role of being fixedly connected with copper bar, does not also need artificial again to connect connecting copper bar and junction block during wiring
It connects, to substantially increase wiring efficiency.
