[0054] On the basis of meeting the signal transmission capability, this embodiment improves the structure of the RF jack, reduces its length by 1 / 3, from 31mm to 20.3mm, and reduces the length and weight of the product. The front shell 2 of the RF jack is connected to the rear shell 7 of the hole by threads, and the jack protective cover 5 and the spring 4 are fixed outside the front shell 2 of the hole. The jack insulator 3, the pin 1, the insulating pad 6, and the first rear shell 8 are sequentially installed in the cavity through clearance fit, and the parts are ensured to be coaxial with each other; the pin insulator 9, the jack 10, the insulating pad 11, and the second rear shell 13 of the RF pin are sequentially installed in the cavity through clearance fit, and the parts are ensured to be coaxial with each other.

[0055] The jack protective cover 5 is connected to the hole front shell body 2, and a spring 4 is provided at the connection part between the jack protective cover 5 and the hole front shell body 2 to form a floating structure, which compensates for the positioning surface accuracy deviation when the RF jack and the RF pin are plugged in.

[0058] The length of the RF jack of this embodiment can be greatly reduced, and the size of the corresponding matching connector will also be reduced accordingly, which can reduce the weight of the product; this embodiment also increases the anti-scratch performance during docking by setting a first chamfer 1-1 and a second chamfer 12-1 on the pin 1 and the pin housing 12; a spring 4 is installed on the RF jack, and when the integrated docking is in use, the floating structure is used to compensate for the positioning surface accuracy deviation, thereby ensuring that the electrical performance of each contact unit is consistent.

[0059] Reference Figure 1 to Figure 2As shown, the lightweight integrated RF contact body of this embodiment includes an RF jack and an RF pin. The front shell 2 and the rear shell 7 of the RF jack are connected by threads, and the jack protective cover 5 and the spring 4 are fixed outside the front shell 2. The jack insulator 3, the pin 1, the insulating pad 6, and the first rear shell 8 are sequentially installed in the cavity through clearance fit, and the parts are ensured to be coaxial with each other; the pin insulator 9, the jack 10, the insulating pad 11, and the second rear shell 13 of the RF pin are sequentially installed in the cavity through clearance fit, and the parts are ensured to be coaxial with each other.

[0060] The accumulated charge at the tip of the first compensation point 1-2 affects the electrical performance of the product. By setting a first boss structure 3-1 on the socket insulator 3, coplanar compensation is formed to optimize the electrical performance; the impedance discontinuity is caused between the second compensation point 1-4 and the third compensation point 8-1, which is compensated by adding an insulating pad 6; the accumulated charge at the tip of the fourth compensation point 12-2 affects the electrical performance of the product. By setting a ring groove structure 9-1 on the pin insulator 9, coplanar compensation is formed to optimize the electrical performance; the accumulated charge at the tip of the fifth compensation point 10-2 is formed by setting a second boss structure 9-2 on the pin insulator 9 to coplanar compensation to optimize the electrical performance; the impedance discontinuity is caused between the sixth compensation point 10-4 and the seventh compensation point 13-1, which is compensated by adding an insulating gasket 11.

[0061] The front housing 2 and the jack 10 are provided with a first circular hole splitting groove structure 2-1 and a second circular hole splitting groove structure 10-1 respectively. When the RF jack and the RF pin are connected, the inner and outer conductors are connected.

[0062] The insertion pin 1 and the pin housing 12 are respectively provided with a first rounded corner 1 - 1 and a second rounded corner 12 - 1 to enhance the guiding function and the anti-scratch performance during docking.

[0063] The surfaces of the plug pin 1 and the plug hole 10 are provided with a first observation hole 1-3 and a second observation hole 10-3 for observing whether the wire is installed in place, and welding is performed after the wire core is installed in place.

[0064] The surfaces of the hole rear shell 7, the first rear shell 8, the needle shell 12 and the second rear shell 13 are respectively provided with a first welding hole 7-1, a second welding hole 8-2, a third welding hole 12-4 and a fourth welding hole 13-2 for solder injection; the second welding hole 8-2 and the fourth welding hole 13-2 respectively weld the first rear shell 8 and the second rear shell 13 to the outer conductor of the adapter wire; the first welding hole 7-1 welds the hole rear shell 7 and the first rear shell 8 together; the third welding hole 12-4 welds the needle shell 12 and the second rear shell 13 together.

[0065] The jack protection sleeve 5 and the needle housing 12 are respectively provided with a first positioning ring 5-1 and a second positioning ring 12-3, which play a positioning role when installed in the connector. Figure 3 and Figure 4 As shown, the RF jack and the RF pin are fixed in the connector by a positioning ring. In the integrated docking state, the floating structure formed by the spring 4 compensates for the positioning surface accuracy deviation and ensures the consistency of the electrical performance of each contact unit.

[0066] like Figure 1 and Figure 5 The length of the existing RF jack with the same function is about 31 mm. The length of the RF jack in this embodiment can be reduced by 1 / 3, from 31 mm to 20.3 mm. The size of the corresponding matching connector will also be reduced accordingly, which can reduce the weight of the product.

[0067] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure.
