Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a structurally robust wire-to-board connector. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between the two. Examples include power plugs / sockets, IC sockets, telephone line plugs, etc.

[0003] Electronic connectors are widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent connection between electrical equipment or wires. Electronic connectors are generally divided into two categories: female connectors and male connectors. Female connectors and male connectors are used in sets to connect and conduct electricity to achieve data transmission. Board-end connectors are a type of female connector, and wire-end connectors are a type of male connector.

[0004] When wire-end connectors and board-end connectors are mated, the wire-end connector is typically inserted directly into the insertion cavity of the board-end connector, allowing the terminals of the wire-end connector and the board-end connector to conduct electricity. The wire-end connector and the board-end connector are then fixed together through an interference fit. While this structure is simple and can basically achieve the conductive connection function, the connection structure between the wire-end connector and the board-end connector is not robust enough. Over time, the wire-end connector and the board-end connector are prone to loosening, leading to poor contact and unstable signal transmission. Furthermore, in vibrating environments, the wire-end connector is prone to detaching from the board-end connector, affecting the normal operation of the equipment, resulting in a poor user experience, and potentially causing short circuits and other problems, posing significant safety hazards. The product quality is also generally poor and cannot meet current requirements. Therefore, it is necessary to research a new technical solution to improve upon these problems. Utility Model Content

[0005] In view of this, the present invention addresses the shortcomings of the existing technology by providing a structurally stable wire-to-board connector.

Over time, the wire-to-board connector and the board connector are prone to loosening, leading to poor contact, unstable signal transmission, and the wire-to-board connector is prone to detaching from the board connector in vibrating environments, affecting the normal operation of the equipment, resulting in a poor user experience, potential short circuits, and other safety hazards.
