Embodiment
[0020] Example: such as Figure 7 As shown, a radio frequency functional electrical connector terminal includes a radio frequency coaxial terminal 1 , a first insulating mounting plate 6 , and a second insulating mounting plate 7 .
[0021] like Figure 4 , Figure 5 As shown, the radio frequency coaxial terminal 1 is provided with an anti-rotation structure of the radio frequency coaxial terminal (an anti-rotation plane 4 of the radio frequency coaxial terminal); Image 6 As shown, the mounting holes of the first insulating mounting plate 6 and the second insulating mounting plate 7 are provided with mounting hole anti-rotation structures (insulation Anti-rotation plane of the mounting plate 5). The anti-rotation plane 4 of the radio frequency coaxial terminal and the anti-rotation plane 5 of the insulating mounting plate are interference fit.
[0022] When in use, the radio frequency coaxial terminal 1 is first loaded into the second insulating mounting plate 7, and then...

The invention discloses an electrical connector terminal with radio-frequency function, comprising a radio-frequency coaxial terminal (1), a first insulating mounting plate (6) and a second insulating mounting plate (7). The radio-frequency coaxial terminal (1) is provided with a radio-frequency coaxial terminal rotation prevention structure; the mounting hole of the first insulating mounting plate (6) and / or the second insulating mounting plate (7) is provided with a mounting hole rotation prevention structure which correspondingly matches with the radio-frequency coaxial terminal rotation prevention structure; the mounting hole rotation prevention structure is in interference fit with the radio-frequency coaxial terminal rotation prevention structure; and the rotation prevention structures can be bilaterally milled and flattened structures, unilaterally milled and flattened structures, roll pattern structures or other rotation prevention structures. The electrical connector terminal has high position precision and no shaking in the insulating mounting plates under the condition of keeping the mounting size of a general connector unchanged, thereby ensuring that the product has good coaxiality during butt joint, the general connector has good electrical performance and EMI (Electro-Magnetic Interference) capacity and reliability, and the product assembly process is simple.
Description
technical field [0001] The invention relates to a radio frequency functional electrical connector terminal. Background technique [0002] Now, due to the gradual increase of electromagnetic environmental pollution in engineering, the requirements for the anti-electromagnetic interference (EMI) ability of many general-purpose connectors are gradually increasing. Under such demands, it is a very good design solution to replace the power terminals of ordinary connectors with RF coaxial terminals with good EMI capability. Since the connector adopting this solution not only has the installation size of a common connector, but also has good EMI capability, it is favored by more and more electronic engineers. [0003] However, since the shape of the RF coaxial terminal of this connector still adopts a standard cylindrical structure (such as figure 1 , figure 2 As shown), an axial positioning elastic collar is used to fix the RF coaxial terminal in the insulating mounting plate ...
