Description

technical field

[0001] The invention relates to the field of electronic equipment, in particular to the field of electric interconnection of printed board components, array antennas and front ends, and in particular to a blind insertion structure of vertical interconnection between boards and an implementation method thereof. Background technique

[0002] Low-frequency and high-frequency signal transmission between printed board components is generally connected through cable components, through-hole plug-in connectors or insulators. However, as the number of vertically interconnected signals between printed board components increases, the traditional vertically interconnected structure has problems such as large volume, complicated assembly, and high cost. In this case, the structure of using SMPM RF coaxial connectors for blind insertion to realize vertical interconnection between boards came into being.

Embodiment

[0046] This embodiment provides a blind insertion structure for vertical interconnection between boards, such as Figure 9 As shown, the structure includes a mounting plate 1, a backing plate, a printed board assembly, a pressure plate, a mounting plate 2 and a spacer.

[0047] Among them, such as figure 2 As shown, there is a concave cavity on the mounting board 1, and the backing plate, the printed board assembly and the pressure plate are sequentially put into the concave cavity for positioning and assembly. The bottom of the cavity is equipped with an SMPM-M connector. There are two positioning pins at the bottom of the cavity. At the same time, pin holes are designed on the corresponding positions of the backing plate, printed board and pressure plate. The gap between the positioning pins and the pin holes is 0.02. -0.05mm, the chamfer of the pinhole opening is 0.3mm×45°; the left and right edges of the mounting plate 1 are also provided with positioning holes.
