Background
At present, mobile phones have become necessities of life of people, and the development of mobile phones gradually evolves from the first functional machines to the current intelligent machines. The handset manufacturer also designs the handset in a direction of reduced thickness for aesthetic reasons. In order to reduce the thickness of the mobile phone, a circuit board in the mobile phone is also converted from an original one-piece circuit board into a mode of adopting a broken board design, and is divided into a main circuit board and a secondary circuit board according to the size, wherein the main circuit board is larger in size and is usually arranged at one end inside the mobile phone; the secondary circuit board is smaller in size, and is usually arranged at the other end inside the mobile phone and is located at the same end of the mobile phone as the antenna radiator. The design of the broken plate inevitably causes the secondary circuit board or the antenna radiator at one end of the mobile phone to be disconnected with the main circuit board at the other end of the mobile phone, so that a radio frequency coaxial line is introduced in the prior art to play a role in signal connection and transmission, wherein one end of the radio frequency coaxial line is connected with the main circuit board, and the other end of the radio frequency coaxial line is connected with the secondary circuit board or the antenna radiator. And the radio frequency coaxial line is arranged between the main circuit board and the secondary circuit board or the antenna radiator. When the radio frequency coaxial line is arranged, in order to avoid the battery, the line is usually routed along the inner edge of the mobile phone.

Meanwhile, the radio frequency coaxial line is routed along the edge of the mobile phone, so that the length of the radio frequency coaxial line is longer, and the loss is larger. In addition, with the coming of 5G, the number of antennas increases sharply, at least two radio frequency coaxial lines are needed in one mobile phone, and the increase of the radio frequency coaxial lines increases the cost of the whole mobile phone.

And an antenna radiator 23 is disposed at a lower end of the mobile terminal, and the antenna radiator 23 may be a portion of a bezel of the mobile terminal.
Referring to fig. 1 and 2, the components of the housing 11 are used to electrically connect the first circuit board 21 and the second circuit board 22, or the first circuit board 21 and the antenna radiator 23. The assembly of the housing 11 shown in fig. 1 and 2 includes the housing 11 located between the first circuit board 21 and the second circuit board 22 and/or the antenna radiator 23, and the signal transmission line 12 penetrating the housing 11 and insulated from the housing 11.
