CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of Chinese Patent Applications Serial Number CN201922109142.2, CN201922107557.6, and CN201922109138.6, filed on Nov. 29, 2019, the full disclosure of which is incorporated herein by reference.

BACKGROUND

Technical Field

The present disclosure relates to the technical field of high-speed connectors, particularly to a wire to board connector.

Related Art

Connector is a component often used in electronic engineering, for setting up a communication between blocked or isolated circuits in the circuit loop, having the current to circulate to realize a predetermined function for the circuit. As an indispensable part of electronic equipment, connectors are produced in various types and configurations according to applications for specific objects, frequencies, powers, and environments. For the industries of automotive, communication equipment, and consumer electronics, the demand for parts is increasingly relying on the development of miniaturization, high-speed and anti-interference, including interference caused by high-speed transmission, such as common electromagnetic interferences at the cable and the system (e.g., circuit board (PCB)), and electromagnetic interferences between the cable and the groundings.

Conventional connectors are all backplane connectors, which are commonly used in large-scale communication equipment, ultra-high-performance servers, and mainframe computers, industrial computers, high-end storage devices. Along with the development of communication technology, the increased signal/high-frequency signal transmission speed brings the issues of interference and crosstalk caused by distributed capacitance and inductance, and attenuation and reflection caused by an impedance mismatch, which needs to be resolved. The backplane connector mainly applies the mating of a male terminal and a female terminal of a connector to perform a connection between two circuit boards, which firstly the male terminal is pressed onto the circuit board followed by inserting the female terminal onto the male terminal. Considering the interconnection between male terminal and female terminal, it needs not only to develop corresponding male and female terminals in response to various industries or product specifications, but two boards of the male terminal also need to be matched with or orthogonal to two boards of the female terminal, resulting in poor transmission performance and poor signal masking. Besides, as the plugging and unplugging operation between the male and female terminals increases, it would cause wearing of the wiring terminals when connecting and disconnecting, which could shorten the service life of the internal wiring terminals.

SUMMARY

The embodiments of the present disclosure provide a wire to board connector to solve the problem of poor structural strength and poor signal transmission performance of conventional connectors.

The present disclosure provides a wire to board connector connected to a circuit board, comprising a main body, a plurality of sheet insulating bodies, a plurality of first covers, and a plurality of second covers. The main body comprises an accommodating groove. The plurality of sheet insulating bodies are disposed in the accommodating groove in parallel along a first direction. A plurality of terminal groups and a plurality of cables correspondingly connected to the plurality of terminal groups are disposed in each of the sheet insulating bodies. The plurality of terminal groups are disposed along a second direction perpendicular to the first direction. The plurality of first covers correspond to the plurality of second covers respectively. Each of the first covers and the second cover corresponding thereto cover two opposite sides of the corresponding sheet insulating body in the first direction.

In the embodiments of the present disclosure, by disposing the terminal groups and the cables on the sheet insulating bodies which are insulative and are disposed at intervals, each of the cables could be electrically connected to the corresponding terminal group, and the connected terminal groups and cables could be isolated from other connected terminal groups and cables. Thus, each of the sheet insulating bodies could be disposed between a first cover and a second cover corresponding thereto, allowing the wire-to-board connector to have excellent structural strength and signal transmission performance.

It should be understood, however, that this summary may not contain all aspects and embodiments of the present disclosure, that this summary is not meant to be limiting or restrictive in any manner, and that the disclosure as disclosed herein will be understood by one of ordinary skill in the art to encompass obvious improvements and modifications thereto.
