Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a quick-connect 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. These connections can be temporary and easily plugged in and out, or they can be permanent joints between electrical devices or wires.

[0004] Current connectors typically consist of an insulating body, multiple terminals, and multiple screws. The terminals are housed within the insulating body, and the screws are movably mounted on it. During wire assembly, the wire is inserted into the insulating body, and the screws are tightened using tools to secure the wire, establishing a conductive connection between the wire and the terminals. While this structure is relatively simple, the manufacturing process is cumbersome, time-consuming, labor-intensive, inefficient, and costly. Furthermore, in vibrating environments, the screw connection is prone to loosening due to inertia, leading to wire detachment, unstable terminal-wire contact, poor signal transmission, and disruption of normal product operation. This results in generally lower product quality, shorter lifespan, less competitiveness, and a poor user experience, failing to meet current needs. Therefore, it is necessary to research a new technical solution to address these issues. Utility Model Content

[0005] In view of the above, this utility model addresses the shortcomings of existing technologies and its main objective is to provide a quick-connect connector. This connector effectively solves the problems of existing connectors, such as numerous assembly steps, cumbersome operation, time and labor costs, low production efficiency, high production costs, and in vibration environments, the screw connection structure is prone to loosening due to inertia, leading to easy wire detachment. Furthermore, the contact between the terminals and the wire is not stable, resulting in poor contact, unstable signal transmission, and impact on normal product operation. Additionally, the product quality is generally poor, the lifespan is short, the product is not very competitive, and the user experience is subpar.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-connect connector includes an insulating body, multiple terminals, and multiple wires. The front end of the insulating body has multiple mounting cavities, and the rear end has multiple guide grooves, each communicating with a corresponding mounting cavity. When inserting the wire at different angles, the guide grooves guide the wire, facilitating better insertion into the mounting cavity and clamping by two elastic arms, thus simplifying production. The multiple terminals are respectively disposed in their respective mounting cavities. Each terminal includes a contact portion, a fixing portion, and a soldering portion integrally formed and connected in sequence. The contact portion includes a main body and elastic arms extending forward from the left and right sides of the main body. A locking point is provided on the main body, positioned between two elastic arms, which improves the connection structure between the terminal and the wire.

The two elastic arms are positioned opposite each other, with each arm having an arc-shaped head. These arms quickly clamp the inserted wires, ensuring a stable connection. The arc-shaped structure and wires make excellent contact, resulting in stable and reliable contact and consistent conductivity. The fixing part is fixedly installed in the mounting cavity, and the welding part extends outwards as an insulating body. One end of each wire passes through a corresponding guide groove and extends into the corresponding mounting cavity. Each end of the wire is positioned between and clamped by the corresponding two elastic arms, and each end of the wire is in contact with and connected to the corresponding two elastic arms. Multiple anti-retraction points abut against the corresponding wires, and the other ends of the wires extend outwards as an insulating body.

[0008] As a preferred embodiment, the bottom surface of the mounting cavity is provided with fixing grooves on the left and right sides, and the fixing part is set in the two fixing grooves for fixing. The structure is simple and easy to manufacture and assemble.

[0009] As a preferred embodiment, the fixing part is provided with protrusions on the left and right sides, and the two protrusions are respectively disposed in the corresponding fixing grooves and interfere with the wall surface of the corresponding fixing grooves, which effectively enhances the stability of the connection structure between the terminal and the insulating body, and makes assembly convenient and quick, bringing convenience to production.

[0010] As a preferred embodiment, a limiting groove is provided on the contact portion, the limiting groove being disposed between the two elastic arms, and a limiting block is provided on the top surface of the mounting cavity, the limiting block being disposed in the limiting groove.

[0011] As a preferred embodiment, the guide groove has a trumpet-shaped structure, and the radius of the guide groove gradually increases from front to back, which is conducive to inserting the wire into place better and faster, bringing convenience to production.

[0012] As a preferred embodiment, the bottom surface of the insulating body is provided with positioning posts on the left and right sides for positioning in conjunction with external parts, which facilitates the better installation of the connector onto the external parts and effectively enhances the stability of the connection structure.

[0013] As a preferred embodiment, the positioning post has a cylindrical structure.

[0014] As a preferred embodiment, the wire includes a core and an outer sheath, the outer sheath covering the core, one end of the core extending outward from the outer sheath and into the mounting cavity, one end of the core being positioned between two elastic arms and clamped by the two elastic arms, one end of the core being in contact with and connected to the two elastic arms, and the anti-reverse locking point abutting against the core.

[0015] As a preferred embodiment, the insulating body is square, and the mounting cavity is also square.

[0016] As a preferred embodiment, there are four mounting cavities and guide grooves, with each guide groove communicating with a corresponding mounting cavity. There are also four terminals, each disposed in a corresponding mounting cavity. There are also four locking points.

Multiple anti-reverse locking points abut against the corresponding wires. The other ends of the multiple wires extend outward from the insulating body. In this connector structure, the two elastic... The arms can quickly clamp the inserted wires, making assembly convenient and fast. This allows for rapid plug-in assembly, reducing production steps, simplifying operation, saving time and labor, significantly improving production efficiency, and lowering production costs. Furthermore, the connection structure between the wire and the two elastic arms is robust, with the arc-shaped structure providing excellent contact with the wire, ensuring stable and reliable contact and consistent conductivity.
