Description

RF connector and method of connecting devices using the same {RF CONNECTOR AND METHOD FOR CONNECTING DEVICES USING SAME}

The present invention relates to an RF connector and a device connection method using the same, and more specifically, to an RF connector that does not require termination and can be used in PCBs, FPCBs, and FRCs that enable contact selection among two contacts, and to a device using the same. It's about how to connect a device.

A connector serves to connect two conductors in a circuit. In other words, a connector allows current to flow from one conductor to another. Specifically, a connector electrically connects two contact points made up of a combination of wires and circuits.

A connector may include a male plug, a female socket, and a locking device that constitute the contact point as essential components. Here, one end of the male plug and one end of the female socket are coupled to each other to form a contact point, and the other end of the male plug and the other end of the female socket are respectively connected to the circuit or wire to be connected to each other through closure. There is only one contact point included in the connector, but the connector must necessarily include one contact part and two connection parts overall, including the two ends. In addition, as additional components, a housing and a mismating prevention device may be included in the connector.

FRC (FPCB RF Cable) is an RF connector based on a flexible printed circuit board. The FRC cable connects the antenna responsible for transmitting and receiving signals in the smartphone and the RF module responsible for signal processing. Small coaxial RF cables were installed in smartphones to perform this role, but they were vulnerable to bending and it was difficult to expand their functionality.

Meanwhile, board-to-board connectors are also called PCB connectors or headers, and are used to connect PCBs or wires and PCBs. Board-to-board allows for a variety of options and functions. Low-cost plastic products or plated products may affect reliability. Mechanical support may be required and additional costs may apply if crimping tools must be used.

Coaxial connectors are the most commonly used connectors in high-speed (RF) applications, including TVs, cell phones, and instrumentation. The conductors are wrapped with a shield to prevent noise from affecting signal integrity, and most coaxial connectors include a latch mechanism. Cable impedance and operating frequency are important criteria in selecting coaxial connector products.

As a technology related to the present invention, an RF coaxial connector for connecting RF signals between boards, disclosed in the Korean Patent Publication, includes a lower case inserted with an insulator that is inserted into an insertion hole of a first circuit board and joined by soldering, and an upper case. It relates to an RF coaxial connector plug including a, and shows a difference in the configuration and effect of the present invention in that the insulator is connected by soldering and does not require termination.

It may be configured to include a step of arranging to fit the device 300 (S120) and a step of storing the conductor in a coupling means for fixing one of the contact points of the connecting device 400 or the connected device 300 (S130). there is.

In the conductor creation step, the conductor 110 may be insulated using an insulator (S111).

The conductor 110 may be configured to include a signal pin 111 and an insulator 112. The signal pin 111 can transmit signals in the form of a discrete cable or coaxial cable. Therefore, the conductor 110 may be configured to further include an external conductor 113 that serves as an EMI shield.

The signal pin 111 can be manufactured through a conductive silicone rubber manufacturing method using silicone rubber and metal powder. The insulator 112 may be implemented using silicone rubber, as an example. The conductor 110 may be manufactured based on silicone rubber and metal powder using an electric field or using 3D modeling techniques.

The conductor 110 may be arranged to fit the terminal of the connection device 400 or the connected device 300 (S120). That is, the conductors 110 can be arranged in rows and columns within the coupling means through the guide 120.

Guide 120 corresponds to the plug body. The guide 120 is made of engineering plastics, such as polyphenylen sulfide (PPS), polyethe ether ketone (PEEK), polysulfone (PSF), SULFONE series, polyamideimide, It can be manufactured using PAI) and polyetherimide (PEI), preferably liquid crystal polymer.

A conductor may be accommodated in a coupling means for fixing one of the contact points of the connecting device 400 or the connected device 300 (S130). The coupling means 130 and 410 may be implemented in the form of a receptacle shell corresponding to the female coupling means 410 and a plug shell corresponding to the male coupling means 130, and they are made of stainless steel, for example, SUS (steel use stainless). It can be manufactured using .

The conductor 110 is an elastic conductor and can be formed using elasticity so that two contact points contact each terminal without a gap. The signal pin 111 and the insulator 112 constituting the conductor 110 may be made of an elastic material and may be in close contact with the first terminal 320 and the second terminal 420. That is, the conductor 110 made of silicone rubber has elasticity in all directions, including the longitudinal direction.

The conductor 110 may be formed so that its impedance is matched depending on the material, contact cross-sectional area, and length. That is, since the impedance changes depending on the material, contact cross-sectional area, and length of the signal pin 111 included in the conductor 110, the signal pin 111 with appropriate impedance can be created depending on the selection of the material, contact cross-sectional area, and length values. You can.

The RF connector 100 according to an embodiment of the present invention may be configured as a discrete connector or a coaxial connector, and is particularly suitable for the structure of a micro-coaxial connector due to miniaturization.

The external conductor 113 can serve as a shield for electromagnetic waves. The external conductor 113 can ensure that the electrical signal transmission of the signal pin 111 is less affected by electromagnetic waves (electrical noise) from the external environment. Additionally, the RF connector 100 can process the ground at multiple points through its coaxial structure.

Additionally, the RF connector 100 according to an embodiment of the present invention has a structure suitable as an RF coaxial connector for connection. Therefore, the RF connector 100 supports various communication standards such as 5G millimeter wave/sub 6, 4G LTE, Wi-fi, Bluetooth, GPS, WiGig, M2M, IoT, SigFox, WiSUN, NB-IoT and LoRa. It can be used as an ideal antenna connection connector.

In addition, the RF connector 100 according to an embodiment of the present invention is a feature of a micro-coaxial connector. In return loss reduction, the signal pin, insulator, and external conductor of the micro-coaxial connector are stable and suitable for characteristic impedance matching. It has properties. Stabilized and matched impedance reduces return loss.

In addition, in terms of insertion loss reduction, the micro-coaxial connector has a larger cross-sectional area of the center conductor compared to FPC/FFC when matching characteristic impedance, so return loss can be minimized.

In addition, in terms of High Shielding Performance, the external conductor plays a role in blocking electromagnetic waves, making it less affected by electromagnetic waves (electrical noise) from the external environment when transmitting electrical signals from the central conductor. Additionally, the shielding effect of the external conductor can help reduce crosstalk between signal lines.

As such, according to an embodiment of the present invention, finishing treatment of the terminal is unnecessary, so problems that may occur due to soldering can be prevented.

Additionally, since terminal finishing is not required, a stable contact point without interference can be maintained even at a short pitch.

Additionally, two contact points can be selectively used to connect and disconnect devices.

Additionally, since there is little physical damage to the contacts due to connecting and disconnecting the connector, the durability of the connector due to the mating cycle is increased.

Additionally, the arrangement of the conductors can be diverse, ranging from single, dual, triple, and quad row.

In addition, the adaptability of the plug shell and receptacle shell is high according to the determination of the conductor arrangement.
