DETAILED DESCRIPTION

[0019] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0020] The existing SMP connector elastic integrated connection mode can solve the problem of poor isolation between channels, but the height between the boards is generally not less than 17.5 mm. The large interconnection height brings difficulties to integration. At the same time, due to the factors such as processing error of the thickness of the multi-layer printed board, the interconnection height error between the boards is large. In order to solve the above problems, a planar interconnection structure with low interconnection between boards, planar elastic connection, large axial tolerance and high isolation is needed to be designed.

[0021] The applicant designs multiple schemes in the research. Scheme one: the plug-in size and the outer diameter of the needle form a 50 ohm impedance matching, then the pin can use a hair button or a spring needle structure. The hair button scheme is used for design. In order to realize the impedance matching inside the adapter, the hair button needs to be used in the embedded pin. From the assembly point of view, it is difficult to embed the hair button in the pin. At the same time, the barb of the pin is fixed with the insulator to prevent the jack from falling off during the compression process of the adapter. Since the thickness of the insulator left for the pin is insufficient, it cannot play a fixed role. This scheme is not feasible.

[0022] Scheme two: considering that the hair button cannot be assembled, a spring needle is used instead of the hair button structure. One end of the spring needle needs to be completely compressed to contact the pin to form impedance matching. At the same time, the pin and the spring needle need to be fixed with barbs. The barb of the pin needs to overcome the spring force of the spring needle and meet the fixed requirements during the compression process. The design size of the barb is too high. The risk of the spring needle in the vibration and impact test environment is higher than that of the hair button. The use environment is limited. If the fixation of the spring needle barb is not enough, the spring needle will easily fall off during transportation.

[0023] In order to solve the above technical problems and avoid the problems of the above two schemes, the applicant designs the embodiments of the present application.
