The terminal box of the 5G signal rectangle shape in one embodiment of the present invention as shown in fig. 1-6 comprises a first housing 1 disposed on the top, a second housing 2 disposed on the bottom, and a third housing 3 disposed in the middle of the two, wherein the third housing 3 is located in a cavity between the first housing 1 and the second housing 2 on both sides for placing a circuit board.

The first casing 1 and the second casing 2 are assembled with the third casing 3 by the

mounting platforms

100, 200 arranged at diagonal positions, and the corresponding third casing 3 is provided with a contact platform 300 contacting with the

mounting platforms

100, 200. Wherein the connecting line of the mounting platform 100 in the first housing 1 and the connecting line of the mounting platform 200 in the second housing 2 are parallel in the vertical direction, and then assembled together by a connecting mechanism arranged between the platforms.

In order to ensure a compact structure of the assembled junction box to reduce signal leakage, the

mounting platform

100, 200 is disposed at an edge position of the first housing 1 or the second housing 2, and the third housing 3 includes an outer side frame 303, a separation plane 304 disposed at a axial position of the outer side frame 303, and the contact platform 300 is disposed on the separation plane 304. When assembled, the outer frame 303 forms the side frame of the entire junction box. Correspondingly, the contact platforms 300 are arranged diagonally, and two groups of contact platforms 300 are respectively arranged on two sides of the separation plane 304.
