Abstract

The invention relates to an elastic piece connecting structure which comprises a first circuit board, an elastic piece and a second circuit board. A containing groove is formed in the upper surface of the first circuit board, the elastic piece comprises a welding end, a contacting end and a bending part, the welding end is arranged at one end of the elastic piece, the welding end is fixed on the upper surface of the first circuit board and connected with the first circuit board in an electrical mode, the contacting end is arranged at the other end of the elastic piece, the bending part is connected with the welding end and the contacting end, and the bending part of the elastic piece is placed in the containing groove. The second circuit board is arranged above the first circuit board in a parallel mode and connected with the contacting end of the elastic piece in the electrical mode, and therefore the second circuit board is connected with the first circuit board through the elastic piece in the electrical mode. According to the elastic piece connecting structure, the elastic piece is arranged in the containing groove which is formed in the upper surface of the first circuit board, the elastic piece is arranged between the first circuit board and the second circuit board, external leaking of radio-frequency signals is reduced notably through shielding of the two circuit boards, and the problem of signal interference between elastic pieces can be improved effectively.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication equipment, and in particular, to a shrapnel connection structure. Background technique [0002] In the design of wireless radio frequency circuits, expensive PA, Power Amplifier, and radio frequency power amplifier circuit boards are usually embedded in ordinary TRX, transmission receiver Unit, and radio frequency transceiver unit circuit boards. A lot of power and radio frequency are required between the two circuit boards. connect. figure 1 It is an overall schematic diagram of a circuit board connection structure in the prior art, figure 2 It is a partial schematic diagram of a circuit board connection structure in the prior art. like figure 1 , figure 2 As shown, the circuit board 101 and the circuit board 102 are connected together by a metal jumper 103, usually by manual welding, one end of the metal jumper 103 is welded on the circuit board 101, and the other end...
