Description

A radio frequency connector between fur button boards

Technical field

The invention belongs to the field of electrical connectors, in particular to a radio frequency connector between fur button boards.

Background technique

In electronic equipment, there are often multiple printed boards, and some printed boards are vertically stacked and installed. However, the interconnection and intercommunication of signals cannot be avoided between printed boards installed in vertical stacks. At this time, inter-board electrical connectors are often required, and inter-board RF connectors are required for radio frequency microwave signals.

The traditional board-to-board RF connectors are paired with male connectors and female connectors. The male connector and the female connector are respectively preset on the two printed boards that need to be connected vertically, and then mated after alignment to complete the vertical connection between the boards. For example, the "board-to-board connector" disclosed in Chinese patent CN201438524U includes an upper socket, a lower socket, and an adapter arranged between the upper and lower sockets through a floating structure. The floating structure can realize the radial and axial alignment of the upper socket relative to the lower socket. to float.

The traditional board-to-board radio frequency connector has the following defects: 1. The traditional board-to-board radio frequency connector needs to be paired with male and female connectors, and the height after mating is relatively high, which increases the gap between printed boards; 2. A group of traditional inter-board RF connectors can only transmit one RF signal; 3. Traditional inter-board RF connectors have high positioning requirements, and it is difficult to align and insert when used in multiple groups; 3. Traditional inter-board RF connectors There is a certain insertion and extraction force when the male and female are mated. When multiple groups are used, the insertion and extraction force is very large, which makes the installation and disassembly of the printed board difficult and easy to be damaged by force; 4. The structure of the traditional inter-board RF connector is complex and difficult to install. It is complex and bulky, which increases the volume and weight of electronic equipment.

These shortcomings have caused great inconvenience and limitations in the use of traditional inter-board RF connectors, and have gradually become an urgent issue in the industry.

Contents of the invention

The purpose of the present invention is to provide an inter-board radio frequency connector with simple structure, simple processing technology, small size, tight and reliable contact, long service life, superior performance, and easy installation and maintenance, so as to make up for the traditional inter-board radio frequency connection It can be applied to the transmission of radio frequency and microwave signals between printed boards installed vertically in layers.

The purpose of the present invention is achieved by arranging a group of random wire pins into an impedance-matched coaxial mode, that is, each group of random wire pins in the coaxial mode uses a random wire pin as the central conductor, and its circumference is uniform. The random wire pins of the cloth are used as the outer conductor to realize shielding and grounding, forming an RF component.

At least one group of coaxial-mode rambling pin radio frequency components and installation accessories arranged on the insulating mounting board form the radio frequency connector between the button boards. This kind of button-to-board RF connector is in end-face contact with the printed board, and the plugging force is zero. Installing a button-to-board RF connector between the upper and lower printed boards can complete the vertical connection between the printed boards , each group of RF components in coaxial mode can transmit one channel of RF signals, and multiple groups of components can transmit multiple channels of RF signals at the same time.

The messy wire pin is a columnar body composed of metal wires, and the metal wires are randomly twisted and distributed.

Using random wire pins as contacts has many advantages: 1. It is very suitable for the transmission of high-frequency signals; 2. High contact reliability; 3. The volume can be made small; 4. It is a flexible pin with its own advantages. Elasticity, both ends can realize elastic connection without welding at the same time; 5. End-face contact can realize zero insertion force.

Install the messy wire pins in the holes on the insulating mounting plate, with both ends exposed outside the insulating mounting plate. The length of rattle pins can also be extended by stacking metal pins.

When the radio frequency connector between the button boards is installed between the upper and lower printed boards, the random wire pins are compressed and rely on their own elasticity to make both ends tightly against the metal pads of the printed board, and the upper and lower printed The corresponding metal pads of the printed board are connected together to complete the vertical connection between the printed board and the printed board. In this way, a button-to-board radio frequency connector can realize the vertical connection of multiple radio frequency signals between laminated printed boards, and it has zero insertion force. When one end of the metal pin is processed into an end-face contact, welding, crimping, and winding structure, the application range of the radio frequency connector between the button boards can be expanded.

This radio frequency connector between button boards is suitable for transmitting high-frequency signals and is in contact with the printed board. Compared with the prior art, it has the following advantages and positive effects: (1) high signal transmission speed; (2) Elastic compression interconnection without soldering and crimping, which is convenient for installation, upgrade and system maintenance; (3) Low installation height, reducing the installation height between boards; (4) Multiple RF signals at the same time; (5) Small size, high performance Excellent; (6) End face contact, insertion force is zero.

This kind of button-to-board RF connector can provide various flexible and reliable interconnection solutions needed, and can be used to connect almost any metal surface to metal surface, and can realize low profile and compact internal interconnection in the PCB board, It is an ideal interconnect solution where high reliability, high-speed signals, small space, high density, and extreme environmental conditions must all be met.
