Embodiment
The present invention is used for the connection of high-voltage great-current electrical equipment or component to cable.
A), the connection procedure of the present invention and cable
Refering to fig. 1, Fig. 2, Fig. 3 rotate clockwise handle 30 around rotation axis 31 first, keep handle 30 in vertical position.
Cable 50 is inserted into, at this point, cable 50 touches by the insulating layer for peelling off cable 50 by the first wiring hole 42 of pedestal 40
First contact surface 21 of elastic slice 20 keeps the first contact surface 21 of elastic slice 20 mobile counterclockwise around elastic slice axle bed 43, until cable 50
It is inserted in place.
Handle 30 is pressed counterclockwise around rotation axis 31, at this point, second of the first cam 32 compressing elastic slice 20 on handle 30
Contact surface 22, the resilient contact 12 of the second cam 33 compressing pressing line frame 10 on handle 30, makes elastic slice 20 collapse deformation, uses elastic slice
20 the first contact surface 21 clamps cable 50, continues to press handle 30, the second cam 33 on handle 30 discharges pressing line frame 10
Resilient contact 12, pressing line frame 10 restores deformation so that the latch hook 13 of pressing line frame 10 and the locked groove 24 of elastic slice 20 are sealed, completion line
Cable 50 and connection of the invention and sealed.
B), the disconnection process of the present invention and cable
Refering to fig. 1, Fig. 2, Fig. 3 rotate clockwise handle 30 around rotation axis 31 first, keep handle 30 in vertical position.
During this period, when handle 30 is rotated clockwise around rotation axis 31, the second cam 33 first on handle 30 oppresses pressing line frame 10
Resilient contact 12, pressing line frame 10 deform, so that the locked groove 24 of the latch hook 13 of pressing line frame 10 and elastic slice 20 is detached from, continue to rotate handle
30, the second contact surface 22 of 32 release elastic sheet 20 of the first cam on handle 30, the first contact surface 21 of elastic slice 20 is to cable 50
Clamping force release.Finally cable 50 is extracted out by the first wiring hole 42 of pedestal 40, i.e., completion cable 50 breaks with of the invention
It opens and unlocks.
Not only play the role of connection terminal for realization pressing line frame 10, but also plays the role of sealed elastic slice 20, the present invention
The design of pressing line frame 10 is made of fixed arm and cantilever, and wherein fixed arm is equipped in inner webs 11 and registration arm 14, cantilever and sets
Flexible contact 12 and latch hook 13；The located arm 14 of pressing line frame 10 is set in the pressing line frame limited post 44 of pedestal 40, pressing line frame
10 inner webs 11 and registration arm 14 constitute fixed arm, and resilient contact 12 and latch hook 13 constitute cantilever, during the work time, fixed
Arm is mutually isolated with cantilever, is independent of each other, it is ensured that pressing line frame 10 is not only with the connection function of terminal, but also has sealed elastic slice
20 effect.
The cantilever of pressing line frame 10 is generated after the compressing of second cam 33 when to prevent handle 30 from opening is plastically deformed and causes
Operational failure, can not restore deformation when handle 30 is closed, and the present invention is provided with enhancing arm 15 in the cantilever segment of pressing line frame 10.
