[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example

[0029] Figure 1 The diagram shows the structure of the connector, which includes a base 10, an RF coaxial connector 20, a pogo pin grounding pin 30, and a connecting strip 40. The base 10 is an injection molded part. The RF coaxial connector 20 and the pogo pin grounding pin 30 are both fixed in the base 10 by injection molding. The connecting strip 40 is used to connect the outer conductor of the RF coaxial connector 20 to the pogo pin grounding pin 30.

[0030] In this embodiment, the RF coaxial connector 20 and the pogopin grounding pin 30 used for the connector both adopt the structure of the prior art.

[0031] According to the above description, the connecting strip 40 connects the RF coaxial connector 20 and the pogopin grounding pin 30 in different ways, including 1+1, 2+2, 4+4, 9+9, etc. For example, 1+1 means that one RF coaxial connector 20 and one pogopin grounding pin 30 are connected through one connecting strip 40, 2+2 means that two RF coaxial connectors 20 and two pogopin grounding pins 30 are connected through the same connecting strip 40, 4+4 means that four RF coaxial connectors 20 and four pogopin grounding pins 30 are connected through the same connecting strip 40, and 9+9 means that nine RF coaxial connectors 20 and nine pogopin grounding pins 30 are connected through the same connecting strip 40.

[0032] See Figures 2-5 The results show the test values ​​for return loss, insertion loss, differential crosstalk, and TDR impedance in a 1+1 connection configuration. Figure 2 The test results are for return loss. Figure 3 The results are for the insertion loss test. Figure 4 The results are for the differential crosstalk test. Figure 5 The results are the TDR impedance test results. Figures 2-5In the diagram, lines 1 and 2 represent the test results of two differential channels, each equipped with a connecting strip 40. The 1+1 connection method is suitable for the transmission of radio frequency signals, high-speed signals, control signals, and current. Radio frequency signals are within 1.5GHz, high-speed signals are within 3.0Gbps, and current is within 1A.

[0033] See Figures 6-9 The results show the test values ​​for return loss, insertion loss, differential crosstalk, and TDR impedance in a 4+4 connection configuration. Figure 6 The test results are for return loss. Figure 7 The results are for the insertion loss test. Figure 8 The results are for the differential crosstalk test. Figure 9 The results are the TDR impedance test results. Figures 6-9 In the diagram, lines 1 and 2 represent the test results of two differential channels, each equipped with a connecting strip 40. The 2+2, 4+4, and higher connection methods are suitable for the transmission of radio frequency signals, high-speed signals, control signals, and current. Radio frequency signals are within 5.0 GHz, and high-speed signals are within 10.0 Gbps.

[0034] Figure 10 The diagram shows the different state structures of the connecting strip 40, from top to bottom: 9+9, 4+4, 2+2, and 1+1 connection modes.

[0035] See Figure 11 The connecting strip 40 is described using a 4+4 connection pattern. The connecting strip 40 is sheet-shaped and is formed by connecting several grounding modules in sequence. Each grounding module includes an arc-shaped portion 41 that contacts the outer conductor of the RF coaxial connector 20 and an arc-shaped portion 42 that contacts the pogopin grounding pin 30. Both arc-shaped portions 41 and 42 are minor arcs. The number of grounding modules is the same as the number of RF coaxial connectors 20. Both ends of the connecting strip 40 have a surrounding body 43 that extends along the arc to form a major arc. One surrounding body 43 extends from the arc-shaped portion 41 and surrounds and fixes the outer conductor of the RF coaxial connector 20. The other surrounding body 43 extends from the arc-shaped portion 42 and surrounds and fixes the pogopin grounding pin 30. The connecting strip 40 can be fixed between the RF coaxial connector 20 and a pogopin grounding pin 30 by the surrounding bodies 43 at both ends.

[0036] Figure 12 What is shown is Figure 1 A magnified view of a portion at point A. The outer conductor sidewall of the RF coaxial connector 20 has an annular groove 21, which is used to fit and embed the connecting strip 40, and to limit the connection of the connecting strip 40 to ensure the stability of the connecting strip 40 after connection and to prevent axial movement.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
