Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
Example 1
As shown in fig. 1, the partition mechanism for a metal junction box of the present embodiment includes a partition plate 10 and a cross member 20.
Two first limiting parts 11 extend downwards from the lower part of the partition plate 10. As shown in fig. 2, correspondingly, two first strip holes 31 matching with the two first limiting portions 11 are formed at the bottom of the metal junction box 30. Preferably, the length of the partition 10 is matched with the distance L between the left and right sidewalls of the metal junction box 30, or the length of the partition is slightly smaller than the distance L, so as to facilitate assembly. During assembly, the partition board 10 is inserted into the metal junction box 20, and the two first limiting portions 11 at the lower portion of the partition board 10 are inserted into the two first strip-shaped holes 31 in a one-to-one correspondence manner, so that the internal space of the metal junction box 30 is partitioned.
The cross beam 20 is disposed on the upper side of the partition board 10, and two second limiting portions 21 extend horizontally outwards from the left and right ends of the cross beam 20. Correspondingly, two second strip-shaped holes 32 matched with the two second limiting parts 21 are arranged on the left side wall and the right side wall of the metal junction box 30. During assembly, the second limiting portion 21 on the left side of the cross beam 20 is inserted into the second strip-shaped hole 32 on the left side wall of the metal junction box 30, and the second limiting portion 21 on the right side of the cross beam 20 is inserted into the second strip-shaped hole 32 on the right side wall of the metal junction box 30. The two second strip holes 32 are formed at positions slightly higher than the upper end of the partition board 10 in height, so that the cross beam 20 is just propped against the upper side of the partition board 10 after being assembled, and the partition board 10 is prevented from being separated upwards.
Fig. 3 shows a metal junction box provided with the partition mechanism. As shown, the length of the metal junction box 30 is the length of two junction box units, and the metal junction box 30 is provided with the partition mechanism to partition the internal space, so that two wiring slots 33 are formed for mounting two panels. It is obvious to those skilled in the art that a switch box with three or more unit lengths may be used, and two or more partition mechanisms may be provided in the metal junction box 30 to partition the metal junction box 30 into three or more wiring slots 33.
Returning to fig. 1, the cross beam 20 is abutted against the upper side of the partition board 10 to prevent the partition board 10 from falling off, but in actual use, the upper part of the partition board 10 is easily shaken forwards or backwards due to excessive force, and even is bent and deformed forwards or backwards. Thus, this example further improves the separation mechanism: a third limiting portion 12 extends upward from the middle of the upper portion of the partition board 10, and correspondingly, a third strip-shaped hole 22 matched with the third limiting portion 12 is formed in the middle of the cross beam 20, and the third limiting portion 12 is inserted into the third strip-shaped hole 22. In this way, when the cross beam 20 is assembled, the cross beam abuts against the upper side of the partition board 10, and the third limiting portion 12 on the upper portion of the partition board 10 and the first limiting portion 11 on the lower portion of the partition board jointly play a limiting role, so that the movement of the upper end and the lower end of the partition board 10 in the front-back direction is limited, and the partition board 10 is stably and firmly installed in the metal junction box 30.
Obviously, to fit the cross member 20 and the partition 10 stably and firmly into the metal junction box 30 requires that the dimensions of the plug-in connection be perfectly matched, otherwise there must be looseness. In actual production, errors are inevitable, and if the first, second and third position-limiting parts 11, 21 and 12 are required to be perfectly matched with the corresponding first, second and third strip- shaped holes 31, 32 and 22, the process requirement is extremely high, which leads to cost increase. The embodiment further improves the structure of the separation mechanism: a portion is cut away at one side, for example, the right side, of the upper portion of the partition 10 so that the height H of the right portion of the partition 10 is low. When the beam 20 is pressed against the upper side of the partition board 10, a certain space is formed between the right side of the upper part of the partition board 10 and the beam 20. Correspondingly, a screw hole 23 is formed at the right part of the cross beam 20. A fastening bolt 24 (see fig. 3) is screwed down into the screw hole 23 of the right portion of the cross member 20 and penetrates the cross member 20, and the lower portion of the fastening bolt 24 abuts against the upper right portion of the bulkhead 10. During the continuous screwing-in of the fastening bolt 24: the fastening bolts 24 push the partition board 10 downward; the fastening bolt 24 and the cross beam 20 are fastened and connected together through thread fit, and by means of reaction force, the fastening bolt 24 and the cross beam 20 are pushed upwards in the same direction by the upper part of the partition board 10; the two ends of the cross beam 20 are inserted into the two second strip-shaped holes 32 on the side walls of the metal junction box 30, and when the cross beam 20 is pushed upwards, the second limiting parts 21 at the two ends are tightly attached to the upper inner walls of the second strip-shaped holes 32. Therefore, even if the first limiting part 11 and the second limiting part 21 cannot be perfectly matched with the first strip-shaped hole 31 and the second strip-shaped hole 32, the assembly is guaranteed to be firm, the requirement on process precision is reduced, the cost is effectively reduced, and the assembly is guaranteed to be firm.
Furthermore, the middle part of the partition board 10 is also provided with a wiring hole 34, and when wiring, a cable can pass through the wiring hole on the partition board 10 from one wiring duct 33 to enter the other wiring duct 33.
Further, locking pieces 36 are arranged on two sides of the middle of the cross beam 20, and fixing holes 37 are arranged in the middle of the locking pieces 36 so as to facilitate installation of the panel.
Example 2
As shown in fig. 3, the metal terminal box of the present embodiment is provided with a partition mechanism of embodiment 1, which partitions the internal space of the metal terminal box 30 into two wiring grooves 33.
Further, the side wall and the bottom of the metal junction box 30 are provided with a plurality of wiring holes 34 for installing pipelines.
Furthermore, the wiring holes 34 are all provided with the shielding pieces 35, the outer edges of the shielding pieces 35 and the inner walls of the wiring holes 34 are fixed together through a plurality of connection points, and when threading through a certain wiring hole 34 is needed, the connection points on the outer edges of the shielding pieces 35 can be broken easily, so that the shielding pieces at the wiring holes 34 are removed.
Further, a plurality of locking pieces 36 are fixed on the inner wall of the upper portion of the metal junction box 30, and a fixing hole 37 is formed in the middle of each locking piece 36 and used for installing a panel (not shown in the figure).
The above embodiments describe the separating mechanism for metal junction box and the structure of junction box in detail, but should not be construed as limiting the present invention. It will be readily understood that modifications, substitutions and further improvements may be made by those skilled in the art based on the teachings of the present invention, but any modifications or equivalents will fall within the scope of the claims of the present invention.
