It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

In one preferred embodiment of the present application, as shown in fig. 1 to 5, a split type photovoltaic junction box comprises a box body 1, a junction plate 2 and a locking assembly 3, wherein a sliding groove 7 is arranged on the inner wall of the bottom of the box body 1, a sliding block 8 is slidably arranged in the sliding groove 7, the junction plate 2 is fixedly arranged on the sliding block 8, so that the junction plate 2 is slidably arranged in the box body 1, and the junction plate 2 and the box body 1 are connected in a matched manner through the locking assembly 3.

When the junction box is normally used, the junction plate 2 is positioned in the box body 1, and the side part of the junction plate 2 is propped against the opening of the side part of the box body 1, so that the circuit connecting part of the junction plate 2 can be sealed in the box body 1; when maintenance is carried out, namely, the line connection part on the wiring board 2 is required to be checked, the locking of the wiring board 2 can be released through the locking component 3, then the wiring board 2 can be moved and extend out of the box body 1, so that the wiring board 2 is exposed, the periphery of the box body 1 is not blocked, and the convenience in repairing is greatly improved; of course, when maintenance is performed, the wiring board 2 can be locked again through the locking assembly 3, so that the movement of the wiring board 2 during maintenance operation is prevented, and the stability is improved.

In this embodiment, the locking assembly 3 has various structural modes, including but not limited to the following three modes:

Structure one: a plurality of limiting holes 9 are formed in the side portion of the wiring board 2, the locking assembly 3 comprises a limiting rod 301, and the limiting rod 301 and the box body 1 are matched through threads.

When the wiring board 2 is locked, the limiting rod 301 can be spirally rotated, so that the limiting rod 301 can move until abutting against one of the limiting holes 9. When the wiring board 2 needs to be adjusted, the limiting rod 301 can be reversely screwed to enable the limiting rod 301 to be far away from the limiting hole 9, and therefore the locking of the wiring board 2 can be released.

And (2) a structure II: a plurality of limiting holes 9 are provided at the side of the terminal block 2, and the locking assembly 3 includes a limiting rod 301, as shown in fig. 4, and the limiting rod 301 may be elastically slidably mounted on the case 1 by a spring 11.

When the wiring board 2 is locked, the limiting rod 301 can prop against one of the limiting holes 9 under the action of the elastic force of the spring 11. When the wiring board 2 needs to be adjusted, the limiting rod 301 can be pulled, so that the limiting rod 301 is far away from the limiting hole 9, and the locking of the wiring board 2 can be released.

It should be noted that, the first structure is similar to the second structure, and the first structure is locked and unlocked by a threaded mode, so that the stability is better. For the second structure, the locking is achieved by the elastic force of the spring 11, and the unlocking is achieved by pulling the limiting rod 301, so that the adjusting mode is faster. Both modes can meet the actual demands, and the person skilled in the art can select according to the actual situation.

It should be further noted that, the number of the limiting holes 9 is at least two, for example, when two limiting holes are used, one limiting hole is the limiting hole when the wiring board 2 is normally used, and the other limiting hole is the limiting hole when the wiring board 2 is moved out of the maximum distance. Of course, if it is desired to limit the movement of the terminal block 2 by different distances, more limiting holes 9 need to be provided between the two limiting holes 9.

And (3) a structure III: as shown in fig. 5, the locking assembly 3 comprises a screw rod 302, the screw rod 302 can be rotatably installed in a chute 7 in the box body 1, and a sliding block 8 connected with the bottom end of the wiring board 2 and the screw rod 302 are in fit connection through threads.

When the wiring board 2 needs to be adjusted, the screw rod 302 can be rotated forward or reversely, and then the wiring board 2 can be driven to move. When the wiring board 2 is locked, the screw 302 is stopped to be stationary.

It should be noted that, compared with the first and second structures, the third structure has the wiring board 2 moving and adjusting by continuously rotating the screw rod 302, and the first and second structures can slide and adjust the wiring board 2 at will as long as the spacing rod 301 and the spacing hole 9 are separated; but the third structure can realize the stop locking of the wiring board 2 at any position, and the first structure and the second structure need to be stopped and locked through the setting position of the limiting hole 9.

In this embodiment, for the locking assembly 3 described above, in the second structure, the spacing rod 301 and the spacing hole 9 may be matched by the magnetic assembly, that is, the spacing rod 301 may be adsorbed in the spacing hole 9 by magnetic force, and the spacing stability may be better under the action of the matching spring 11. Of course, the spring 11 is prevented from being disabled after long-term use, and the magnetic component can play a limiting role.

The magnetic assembly comprises two magnetic blocks, the two magnetic blocks are respectively arranged in the limiting rod 301 and the limiting hole 9, and after the limiting rod 301 is inserted into the limiting hole 9, the two magnetic blocks can be adsorbed together.

Of course, the magnetic component can also be a magnetic block and an iron block, which have two mounting modes:

mode one: the magnetic attraction block is fixedly arranged on the limiting rod 301, and the iron block is fixedly arranged in the limiting hole 9.

Mode two: the magnetic attraction block is fixedly arranged in the limit hole 9, and the iron block is fixedly arranged on the limit rod 301.

In this embodiment, as shown in fig. 4, for the locking assembly 3 adopting the first and second structures, the ring body 10 may be installed at the end of the limiting rod 301 away from the limiting hole 9.

When the limit rod 301 is operated, a finger can be inserted into the ring body 10, so that the limit rod 301 can be pulled or rotated conveniently, and convenience is improved.

In this embodiment, as shown in fig. 2, the wiring board 2 includes a line board 202 and a side board 201, a sealing member (usually a sealing ring) is provided outside the side board 201, and when the wiring box is normally used, i.e. the wiring board 2 will be located in the box body 1, the side board 201 can just cooperate with the opening, and the sealing member will abut against the opening at this time, so as to improve the tightness during use; of course, the wire holder 6, which is wire-connected to the terminal box, is also provided outside the side plate 201.

In this embodiment, as shown in fig. 1 and 2, the top end of the box body 1 is of an open structure, and the top end of the box body 1 is detachably provided with a cover plate 4, and the cover plate 4 can be connected with the box body 1 through bolts, so that the inside of the box body 1 can be maintained or cleaned through the opening of the cover plate 4. Of course, the top end of the cover plate 4 can be provided with a window assembly 5, and the window assembly 5 is used for being matched with the inside of the box body 1, so that the inside wiring board 2 can be observed in real time without opening the box body 1, and convenience is improved.
