Description

Technical Field

[0001] The present invention relates to a wire clamp, and more particularly to a wire clamp connector, which can clamp and electrically connect wires on a cable and prevent the wires from being damaged, thereby increasing the number of plug-in and pull-out cycles of the wires. Background Art

[0002] The existing wire clamp connector can be welded on the circuit board of the electronic device and is used to clamp and electrically connect the wires on the cable. Through the wire clamp connector, the electronic device can be connected to other devices through the cable.

[0003] US Patent No. 8721376 discloses a wire clamp connector having a cage-shaped structure and a box-shaped structure, wherein the cage-shaped structure includes an inclined contact tip for contacting a wire, and a contact clamping point is formed on the contact tip to contact the exposed core of the wire. However, the contact tip of the wire clamp connector is sharpened and is easy to thin the wire when the wire is plugged in or out, causing the wire to be damaged and lose the ability to be fixed on the wire clamp connector, so that the wire is difficult to be firmly electrically connected to the wire clamp connector. Summary of the invention

[0004] In view of the disadvantage that the existing wire clamp connector is easy to damage the wire, the inventor improves the shortcomings and defects and further invents a wire clamp connector.

[0005] The main purpose of the present invention is to provide a wire clamp connector, which can clamp and electrically connect the wires on the cable and avoid damage to the wires, thereby increasing the number of plug-in and pull-out cycles of the wires.

[0007] Through the above-mentioned technical means, the two clamping springs of the wire clamp connector can firmly clamp the wire core of the wire, and the arc clamping parts of the two clamping springs are in smooth contact with the wire core of the wire without rubbing or thinning the wire core, thereby preventing the wire from being worn out after multiple plugging and unplugging and no longer being able to be stably clamped by the wire clamp connector. Therefore, the wire clamp connector can maintain the durability of the wire and ensure the stability of the electrical connection.

[0008] The top surface of the aforementioned bottom plate protrudes backward to form a downwardly inclined guide piece; the wire clamp connector further includes an upper guide plate, which protrudes forward from the rear welding plate and has an upper elastic arm, an upper inclined guide piece and an arc turning portion, the upper elastic arm protrudes forward and obliquely upward from the rear welding plate, the upper inclined guide piece protrudes backward and downward from the front end of the upper elastic arm, and the arc turning portion is between the upper inclined guide piece and the upper elastic arm.

[0009] The two clamping springs together present an X-shaped appearance.

[0010] Another object of the present invention is to provide a wire clamp connector assembly, which includes a wire clamp connector and an insulating shell, wherein: the wire clamp connector includes a base plate, a rear welding plate and two clamping springs; the rear welding plate protrudes vertically upward from the rear end of the base plate; the two clamping springs protrude forward from the two sides of the rear welding plate, each clamping spring is V-shaped, and has a first inclined elastic arm, a second inclined elastic arm and an arc clamping portion, the first inclined elastic arm extends obliquely inward from one side of the rear welding plate toward the front, the second inclined elastic arm extends obliquely outward from the front end of the first inclined elastic arm toward the front, the arc clamping portion is formed on the first inclined elastic arm and the second inclined elastic arm, and the arc clamping portions of the two clamping springs are close to each other; an accommodating space is formed on the insulating shell to accommodate the wire clamp connector.
