Description

A kind of electrical connector between fur button boards

Technical field

The invention belongs to the field of electrical connectors, in particular to an electrical 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.

The traditional inter-board electrical connectors are used in pairs 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.

The traditional board-to-board electrical connector has the following defects: 1. The traditional board-to-board electrical 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. Traditional board-to-board electrical connectors have high positioning requirements, and it is difficult to align and insert when used in multiple groups; 3. Traditional board-to-board electrical connectors have a certain insertion force when male and female are mated, and plugging and unplugging when using multiple groups The force is very large, which makes it difficult to install and disassemble the printed board and is easily damaged by force; 4. The traditional inter-board electrical connector is large in size, which increases the volume and weight of electronic equipment; 5. The traditional inter-board electrical connection Transmitters are only suitable for passing low-frequency signals and low-speed transmissions. These shortcomings have caused great inconvenience and limitations in the use of traditional inter-board electrical connectors, and have gradually become an urgent problem in the industry.

Contents of the invention

The purpose of the present invention is to provide an inter-board electrical connector with 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 shortcomings and disadvantages of traditional inter-board electrical connectors. It is suitable for the transmission of low-frequency and high-frequency signals between printed boards installed vertically in stacks.

The object of the present invention is achieved like this: a group of messy wire pins and accessories are installed on the insulating mounting board to form an electrical connector between the fur button boards. This kind of button-to-board electrical connector is in end-face contact with the printed board, and the plugging force is zero. Installing a button-to-board connector between the upper and lower printed boards can complete the vertical connection between the printed boards.

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 electrical connector between the button boards is installed between the upper and lower printed boards, the messy wire pins are compressed and rely on their own elasticity to make both ends tightly against the metal pads of the printed boards, 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 fuzz button inter-board electrical connector can realize the vertical connection between the stacked printed boards, and it has zero plugging force. When one end of the metal pin is processed into an end-face contact, welding, crimping, and winding structure, it can realize zero insertion force and no welding pressure connection between the printed board pad and the wire, expanding the application of the button-to-board electrical connector scope.

This electrical 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) The number of connection points can be from 1 to 7000; (5) Small to 1mm or greater contact spacing; (6) end face contact, insertion force is zero.

This fur button board-to-board electrical connector can provide a variety of 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 PCB boards, It is an ideal interconnect solution where high reliability, high-speed signals, small space, high density, and extreme environmental conditions must all be met.
