In addition, in order to facilitate the electrical connection between the circuit board 2 and the main control system of the display screen, the circuit board 2 and the main control system are electrically connected through the wiring 4, and the wiring 4 can penetrate through the wire outlet 12 to be electrically connected with the main control system after being electrically connected with the circuit board 2.

As shown in fig. 3, 5, 6 and 7, any side wall of the box cover 15 is provided with a third groove 121, a side wall of the box body 14 opposite to the any side wall of the box cover 15 provided with the third groove 121 is provided with a fourth groove 122, the third groove 121 is opposite to the fourth groove 122, and the third groove 121 and the fourth groove 122 enclose a wire outlet 12 after the box cover 15 is connected to the box body 14, that is, the third groove 121 and the fourth groove 122 are combined to form the wire outlet 12. When the box cover 15 is removed from the box body 14, the wire outlet 12 is split into the third groove 121 and the fourth groove 122, so in practical situations, when the box cover 15 is removed from the box body 14, the wire outlet 12 is also split, and therefore the connection wire 4 can be conveniently taken out of the wire outlet 12 or installed in the wire outlet 12.

In addition, the third grooves 121 and the fourth grooves 122 are both multiple and have the same number, specifically, in this embodiment, the third grooves 121 and the fourth grooves 122 are both two, so the number of the outlet holes 12 is also two, and the two outlet holes 12 are oppositely disposed on the left and right two box walls of the terminal box 1, of course, they may not be oppositely disposed according to the requirement, or they may be disposed on the front and back two box walls of the terminal box 1, or one is disposed on the front box wall or the back box wall, and the other is disposed on the left box wall or the right box wall, etc., of course, the number of the outlet holes 12 may be increased according to the requirement, and the disposed positions may be changed arbitrarily, as long as the invention does not depart from the scope of the present invention.

Because the number of the outlet holes 12 is two, the proper outlet hole 12 can be selected for the wiring 4 according to the installation position of the junction box 1 or the connection position of the wiring 4 and the circuit board 2. The junction box 1 adopts a design mode that wires can be led out from left and right sides, and the wire outlet holes 12 are formed in the left and right sides of the junction box 1, so that the mounting position of the junction box 1 is not limited (including upside-down mounting), and the mounting position is more flexible.

In the above case, when the box cover 15 is opened, the plug hole and the outlet hole 12 become grooves, and the plug 3 and the connection terminal 4 can be directly taken out from the grooves; when the connector is re-installed, the plug connector 3 and the wiring 4 are re-placed into the groove, the box cover 15 is covered to enable the plug connector 3 to be installed into the jack, and the wiring 4 penetrates through the wire outlet hole 12, so that the assembly and disassembly are more convenient.

In addition, as shown in fig. 1 to 5, the circuit board 2 is disposed on the box cover 15, and the circuit board 2 may be fixed on the box cover 15 by means of snap-fitting, screws, gluing, or spot welding. When the box cover 15 is opened, the circuit board 2 is detached together with the box cover 15, so that the danger of electric shock caused by touch due to the fact that the circuit board 2 is left in the box body 14 is avoided. And circuit board 2 follows lid 15 and takes out together, also is more convenient for the maintenance to circuit board 2, and two bayonet joint 3 all set up on circuit board 2, therefore circuit board 2 when taking off, two bayonet joint 3 also can follow together.

As shown in fig. 1 to 5, in order to detachably connect the box cover 15 and the box body 14, at least one through hole 141 is formed on a side wall of the box body 14; the box cover 15 has at least one clamping member 151, and each clamping member 151 is clamped with each through hole 141. The clamping member 151 includes: the elastic plate 1511 and the hook 1512, the elastic plate 1511 extends from the box cover 15 downward into the cavity, and the hook 1512 is disposed opposite to the through hole 141, extends from the elastic plate 1511 into the through hole 141, and is operably located in the through hole 141.

The through holes 141 are four, the clamping pieces 151 are also four, each through hole 141 and each clamping piece 151 are arranged in a one-to-one correspondence manner, when the box cover 15 is covered on the box body 14, the hooks 1512 are located in the through holes 141, when the box cover is required to be detached, tools are required to be adopted to abut against the hooks 1512 outside the terminal box 1, and the clamping pieces 151 further comprise elastic plates 1511, so that the hooks 1512 can be taken out of the through holes 141, and the box cover 15 can be detached from the box body 14. Therefore, the box cover 15 cannot be opened from the outside without using a tool, and the safety of the junction box 1 is improved.

Of course, besides the above-mentioned mounting method, the box cover 15 may also be mounted on the box body 14 by screws, for example, the box cover 15 and the box body 14 are both provided with threaded holes 5, which can be detachably connected by screws, or the box cover 15 is provided with unthreaded holes, and the box body 14 is provided with threaded holes 5.

Because the space in the case of the display screen, especially the indoor small-distance LED display screen is narrow, the junction box 1 is arranged in the case, the case is provided with more reinforcing ribs, and the installation position of the junction box 1 is limited. For this reason, the present embodiment further improves the case body 14 of the terminal box 1, and due to the existence of the plug 3, the bottom of the case body 14, namely the lower part of the circuit board 2, has a certain space margin, as shown in fig. 3, 5 and 7, so that a part of the bottom of the case body 14 faces the cavity 11 and protrudes towards the box cover 15 to form a protruding portion 142, a recessed avoiding area 143 is arranged below the protruding portion 142, and a reinforcing rib in the display screen is arranged in the avoiding area 143. Meanwhile, the projecting portion 142 supports the wiring board 2.

Thus, on the one hand, the relief area 143 allows the internal ribs of the display screen to pass through, and on the other hand, the protrusion 142 can serve as a boss for mounting the circuit board 2. When the junction box 1 is installed, the junction box 1 can directly stride across the reinforcing ribs, the phenomenon that the junction box 1 cannot be installed due to the fact that the inner space of the display screen is too narrow is avoided, and the junction box 1 is installed more flexibly.

The utility model discloses the second embodiment relates to a terminal box for display screen, and this terminal box for display screen is terminal box 1 in the first embodiment.
