After the external wire X needs to be removed and the positioning piece 301c is released from positioning the ferrule 301b, the first spring 301d can push the ferrule 301b to reset, and the deformed end 401 and the second wire clamp 202 are released from clamping and positioning the external wire X.
Example 3
Referring to fig. 2 to 7, this embodiment differs from the above embodiments in that: the photovoltaic power generation transformer junction box further includes a reminder mechanism 500 comprising a coaxial tube 501 secured to the inside of the inner compartment 102 in concentric relationship with the inner shaft 301 a.
The alert mechanism 500 further includes a rotatable ring member 502 rotatably disposed on the outside of the ferrule 301b and coupled to the coaxial tube member 501.
Two limiting rings 301b-1 are fixed on the outer side of the sleeve 301b, the rotating ring piece 502 is located between the two limiting rings 301b-1, and can rotate between the two limiting rings 301b-1, the coaxial pipe 501 plays a limiting role on the rotating ring piece 502, when the sleeve 301b moves in a first direction, the rotating ring piece 502 can be driven to move in the first direction, and in the process that the rotating ring piece 502 moves in the first direction, the rotating ring piece 502 can rotate positively.
Specifically, an outer groove 501a is formed in the outer side of the coaxial pipe fitting 501 at a position corresponding to the second wire clamp 202, an inner spiral groove 501b is symmetrically formed in the inner side of the coaxial pipe fitting 501, and the outer groove 501a is communicated with the inner spiral groove 501 b; the rotary ring 502 includes a ring body 502a rotatably disposed on the outer side of the ferrule 301b, and a guide arm 502b fixed on the outer side of the ring body 502 a; the guide arm 502b is slidably connected to the inner side of the inner spiral groove 501 b.
The width of the outer groove 501a is smaller than that of the inner spiral groove 501b, and when the swing amplitude of the pressure receiving body 202d in the second wire clamp 202 is too large, the pressure receiving body 202d can rotate to the inner side of the outer groove 501a, and enter the inner side of the inner spiral groove 501b through the outer groove 501a, and the pressure receiving body 202d entering the inner side of the inner spiral groove 501b can block the guide arm 502b.
The coaxial tube 501 has a third through slot 501c formed at a corresponding position of the second through slot 102c, the third through slot 501c is formed at a side wall of the coaxial tube 501, the beam 201a can pass through the coaxial tube 501 through the third through slot 501c, the third through slot 501c is formed so that the beam 201a is not blocked by the coaxial tube 501 when moving, the fixed shaft 202a is fixed at an inner side of the first through slot 102b, the beam 201a passes through the second through slot 102c and the third through slot 501c, the second through slot 102c and the third through slot 501c have the same slot width as the beam 201a, and both ends of the beam 201a extend to positions corresponding to deformed ends 401 of the conductive member 400 through the second through slot 102c and the third through slot 501 c.
When the ferrule 301b moves in the first direction, the ring body 502a can be driven to move in the first direction, in this process, the guide arm 502b moves along the inner spiral groove 501b, so that the ring body 502a rotates, if the external wire X is not located between the lower abutting body 202c and the deformed end 401, the lower abutting body 202c is not blocked by the external wire X when rotating toward the deformed end 401, in this case, the pressed body 202d swings down too much, and reaches the inner side of the inner spiral groove 501b through the outer groove 501a, and blocks the guide arm 502b, so that the guide arm 502b cannot continue to move down along the inner spiral groove 501b, so that the ring body 502a cannot continue to move down, so that the ferrule 301b cannot continue to reach the position of the positioning piece 301c to position the ferrule 301b, and an operator can learn that the external wire X on the inner side of the junction box is not clamped by the lower abutting body 202c and the deformed end 401 through the ferrule 301b cannot be locked.
Further, the positioning member 301c includes a positioning ring 301c-1 fixed on the rotating ring member 502, a locking pin 301c-2 abutting against the positioning ring 301c-1 and extending to the outside of the housing 101, and a locking hole 301c-3 provided on the positioning ring 301 c-1.
In the initial state, the lock hole 301c-3 and the lock bolt 301c-2 on the positioning ring 301c-1 are dislocated, the lock bolt 301c-2 is slidably connected to the housing 101, one end extends to the outer side of the housing 101, the other end abuts against the upper surface of the positioning ring 301c-1, when the ferrule 301b starts to be pressed and moves in the first direction, the positioning ring 301c-1 can be pushed to rotate forward, when the lower abutting body 202c and the deformed end 401 clamp the end of the external wire X, the lock bolt 301c-2 can correspond to the position of the lock hole 301c-3, the end of the lock bolt 301c-2 enters the inner side of the lock hole 301c-3, so that the positioning ring 301c-1 and the ring body 502a cannot rotate, and therefore the guide arm 502b cannot move inside the inner spiral groove 501b, and the ring body 502a and the ferrule 301b cannot move, and the outer side can position the ferrule 301b, and therefore the lower abutting body 202c and the deformed end 401 stably clamp the external wire X.
Further, the synchronous pressing member 302 includes a through-tube body 302a disposed on the cross-beam body 201a, a pressing ring 302b fixed on the inner side of the through-tube body 302a, a movable column 302c slidably connected with the pressing ring 302b, and a second spring 302d having one end pressing against the movable column 302c and the other end pressing against the pressing ring 302 b.
To be able to push the pressure body 202d, the end of the movable column 302c extends above the pressure body 202d.
The rest of the structure is the same as in embodiment 2.
The operation process comprises the following steps: when the external lead X is normally located between the lower contact 202c and the deformed end 401, the ferrule 301b is pushed to move in the first direction, and the ferrule 301b can be driven to move in the first direction during the movement of the ferrule 301b, and the guide arm 502b moves along the inner spiral groove 501b during the movement of the ferrule 502a, so that the ferrule 502a rotates, and the ferrule 301b drives the movable post 302c to move in the first direction.
When the movable column 302c starts to collide with the pressed body 202d, the pressed body 202d can drive the rotating ring 202b to rotate, so that the lower abutting body 202c collides with the external wire X, the external wire X can avoid the lower abutting body 202c from continuing to rotate, and further, the pressed body 202d can be prevented from continuing to rotate, so that the pressed body 202d cannot enter the inner side of the outer groove 501a, in the process, the beam body 201a continues to downwards drive the abutting ring 302b to continue downwards, the second spring 302d can be pressed, the movable column 302c keeps the position unchanged, and after the second spring 302d is pressed, larger pressure is applied to the movable column 302c, so that the movable column 302c can provide larger clamping force for the second wire clamp 202.
When the ferrule 301b moves in the first direction, the positioning ring 301c-1 can be pushed to rotate forward, when the lower abutting body 202c and the deformed end 401 clamp the end of the external wire X, the lock plunger 301c-2 can correspond to the lock hole 301c-3 in position, the end of the lock plunger 301c-2 enters the inner side of the lock hole 301c-3, so that the positioning ring 301c-1 and the ring body 502a cannot rotate, and therefore, the guide arm 502b cannot move inside the inner spiral groove 501b, so that the ring body 502a and the ferrule 301b cannot move, and the outer side positions the ferrule 301b, so that the lower abutting body 202c and the deformed end 401 stably clamp the external wire X.
When unlocking, the lock bar 301c-2 may be lifted in the second direction.
When the position of the external wire X is not between the lower abutting body 202c and the deformed end 401, the lower abutting body 202c is not blocked by the external wire X when rotating toward the deformed end 401, in this case, the pressed body 202d swings downward too much and reaches the inner side of the inner spiral groove 501b through the outer groove 501a, and blocks the guide arm 502b, so that the guide arm 502b cannot continue downward along the inner spiral groove 501b, and the ring body 502a cannot continue downward, so that the ferrule 301b cannot continue downward to reach the position of the positioning piece 301c to position the ferrule 301b, and an operator can know that the external wire X inside the junction box cannot be clamped by the lower abutting body 202c and the deformed end 401 through the ferrule 301 b.
