Groove 102-4-1 on installation portion 102-4 coordinates location, and after making plate, obturating plug 104 is solid with binding post 102
Fixed；When after plate, termination 10 is installed on circuit breaker base 20, the bag of obturating plug 104 after plate
Cover installation portion 102-4 at least some of of portion 104-4 cladding binding post 102.
In certain embodiments, after plate, obturating plug 104 can be made up of elastic insulating material；Now, plate
Protruding 104-4-1, the installation of binding post 102 can also not be had in covering portion 104-4 of rear obturating plug 104
Corresponding groove 102-4-1 can also not be had on portion 102-4；Due to the characteristic of elastic insulating material, no
Only can realize the tight fit of the connecting portion 104-2 of obturating plug 104 and circuit breaker base 20 after plate, and
The tight of covering portion 104-3 of obturating plug 104 after plate and the installation portion 102-4 of binding post 102 can be realized
Coordinate, be equivalent to dual fail-safe, relatively reliable.
In certain embodiments, after plate, obturating plug 104 can also be made up of non-elastic insulating material；This
Time, after plate the connecting portion 104-2 of obturating plug 104 can be pressed in the groove on circuit breaker base 20 and with
Groove on circuit breaker base 20 forms interference fit, so that obturating plug 104 and chopper after plate
Pedestal 20 is fixed.
In the embodiment described above in association with Fig. 2 to Fig. 4, because connecting the installation portion 102-of post 102
Having 2 blind holes 102-4-2 being set to 90 degrees on 4, the terminals 102-2 of binding post 102 can pacify
Dress up any one the wiring direction in 2 wiring directions in 90 °, it is simple to the wiring of chopper,
The range of application of chopper can be expanded.2 placement positioning axles 106 it are provided with on circuit breaker base 20
Groove 204, it is simple to change binding post 102 wiring direction, the most either rotate clockwise still
Rotating counterclockwise, any direction half-twist can change wiring direction；And need not a direction rotation
Turning 90 °, another direction rotates 270 °.After the wiring direction of binding post 102 determines, it is installed
Portion 102-4 is fastened by the securing member of such as bolt etc with the entry/exit line connecting plate 202 in chopper
Together.
In certain embodiments, the one of the terminals 102-2 of the close binding post 102 of binding post 102
End can also be provided with through hole；It is provided with cross-like groove on circuit breaker base 20；Orientation axes 106
Through hole on binding post 102, falls in the cross-like groove on circuit breaker base 20 wherein
One in groove；When orientation axes 106 falls into other in crisscross grooves in groove, binding post
The direction half-twist of 102.That is, it is also possible to realize binding post 102 by the way
Direction regulates.
Fig. 5 is that after illustrating the plate for chopper shown in Fig. 1, termination is installed with circuit breaker base
Partial sectional view together.As it is shown in figure 5, in some embodiments it is contemplated that electric clearance and
The restriction of creep age distance, the U-shaped boss as the connecting portion 104-2 of obturating plug after plate 104 has following
One or more features in feature: 1) this U-shaped boss end face 104-6 and bottom surface 104-7 between
Distance more than 5mm；And 2) between medial surface 104-8 and the binding post 102 of this U-shaped boss
There is the gap more than 1mm, it is easy in gap, increase insulant, be of value to and not increasing
The value of electric clearance and creep age distance is significantly improved on the premise of adding.Above-mentioned two feature combines and can become
Increase creep age distance again, meet electric clearance and the requirement of creep age distance of regulation, thus reduce at double
The physical dimension of product short transverse, meets miniature requirement, increases product competitiveness.It addition, plate
Between the bottom surface 104-7 and the bottom surface 104-9 of covering portion 104-4 of the connecting portion 104-2 of rear obturating plug 104
