Description

Technical Field

[0001] This utility model relates to a connector, specifically a quick-connect connector. Background Technology

[0002] A connector is a device that connects two active devices and is used to transmit current or signals. The main application areas for electrical connectors include transportation, communication, networking, IT, medical, and home appliances. The rapid development of product technology and the rapid growth of the market in these application areas have strongly driven the development of connector technology. To date, connectors have evolved into a series of specialized products with a complete range of types and specifications, diverse structures, specialized focuses, distinct industry characteristics, and standardized systems. Existing connectors use screw-based wiring, requiring tools such as screwdrivers, making wiring and disconnection cumbersome, time-consuming, and labor-intensive. Furthermore, these connectors suffer from drawbacks such as complex structure, unreliable performance, and inconvenient assembly. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick-connect connector that is simple in structure, stable and reliable in performance, convenient in assembly, and reliable in connection.

[0004] To achieve the above objectives, this utility model employs a quick-connect connector, including a base, a cover disposed on the base, and a conductive clamping assembly. A receiving cavity for housing the conductive clamping assembly is formed between the base and the cover. The conductive clamping assembly includes a busbar disposed within the base and at least one spring contact disposed on the busbar. The busbar has multiple positioning holes arranged in a rectangular array to mate with the spring contact. The busbar is vertically bent at both sides corresponding to the positioning holes, forming two contact plates. One end of the spring contact has… An elastic support arm engages with a positioning hole. The tail of the elastic support arm has a hook-shaped body that engages with a positioning groove in the positioning hole. The other end of the spring has an elastic contact arm that passes through the positioning hole and abuts against the contact straight plate. The tail of the elastic contact arm has a bent limiting piece that engages with a limiting groove in the contact straight plate. A clamping space for clamping wires is formed between the elastic contact arm and the contact straight plate. A wire-passing hole is provided on the base corresponding to the clamping space. A lever for driving the elastic contact arm is rotatably provided on the base.

[0005] The advantages of the above structure are: the conductive clamping assembly adopts a modular design, enabling modular assembly of the connector and improving assembly efficiency. A spring is provided on the busbar, and a clamping space is formed between the elastic contact arm of the spring and the contact plate of the busbar. During wiring, rotating the lever drives the elastic contact arm of the spring to move, allowing the wire to be inserted into the clamping space. The elastic contact arm of the spring presses the wire firmly within the clamping space. By rotating the lever, the connector can be wired and disconnected, making connection and disconnection more convenient and efficient. Furthermore, the spring pressing the wire ensures a more reliable connection between the wire and the busbar. The elastic contact arm is engaged in the limiting groove of the contact plate by a bending limiting piece, thus ensuring a more reliable clamping of the elastic contact arm and the contact plate. Therefore, this connector has the advantages of simple structure, stable and reliable performance, convenient assembly, reliable connection, and quick connection and disconnection.

The two snap-fit ​​posts are inserted into the two snap-fit ​​holes, forming a snap-fit ​​engagement between the two snap-fit ​​posts and the manifold. The cover body is snapped onto the manifold by the two snap-fit ​​posts, thereby facilitating the assembly of the cover body and the manifold and making assembly more convenient.

[0007] Specifically, the cover body has two snap-fit ​​grooves corresponding to the two contact plates, with one side of each contact plate inserted into one of the two snap-fit ​​grooves, forming a snap-fit ​​engagement between the cover body and the two contact plates. The snap-fit ​​grooves on the cover body position the contact plates, thereby ensuring a tighter connection between the manifold and the cover body.

[0008] Specifically, the busbar has multiple snap-fit ​​tabs on one side corresponding to the two contact plates, and the base has multiple slots that mate with the snap-fit ​​tabs. The snap-fit ​​tabs are inserted into the slots, forming a snap-fit ​​engagement between the snap-fit ​​tabs and the base. The busbar's engagement with the base via these snap-fit ​​tabs facilitates assembly and improves assembly efficiency.

[0009] Specifically, one end of the lever has two symmetrically distributed arc-shaped protrusions extending into the accommodating cavity. The elastic contact arm has two arc-shaped grooves that mate with the two arc-shaped protrusions. The two arc-shaped protrusions move with the lever and respectively abut against the two arc-shaped grooves, forming a linkage between the elastic contact arm and the two arc-shaped protrusions. The lever drives the elastic contact arm of the spring through the arc-shaped protrusions, ensuring that the lever can reliably drive the elastic contact arm, thereby improving the working reliability of the connector.

[0010] Specifically, the lever is symmetrically provided with two positioning protrusions, and the base is provided with two positioning grooves that mate with the two positioning protrusions. The two positioning protrusions are rotatably disposed within the two positioning grooves, forming a rotatable connection between the two positioning protrusions and the base. The lever's rotatable placement within the two positioning grooves of the base via the two positioning protrusions ensures reliable operation of the lever on the base, thereby improving the connector's operational reliability.

[0011] Specifically, the spring is basically V-shaped, and a reinforcing rib is provided on one side of the spring. The reinforcing rib can enhance the fatigue strength of the spring, thereby improving the connection reliability of the connector wiring.

[0012] Specifically, the base is provided with multiple snap-fit ​​plates that mate with the cover. Each snap-fit ​​plate is provided with a snap-fit ​​block, and the cover is provided with snap-fit ​​holes that mate with the snap-fit ​​blocks. The snap-fit ​​blocks engage within the snap-fit ​​holes, forming a snap-fit ​​connection between the snap-fit ​​plates and the cover. The base is snapped into the cover via the snap-fit ​​plates, thereby facilitating the assembly of the base and the cover and improving assembly efficiency.

[0013] Specifically, the base has two symmetrically arranged inserts, and the cover body has two slots that mate with the two inserts. The two inserts are inserted into the two slots, forming a snap-fit ​​engagement between the two inserts and the cover body. The base is inserted into the two holes of the cover body via the two inserts, thus facilitating the assembly of the base and the cover body and making assembly more convenient.
