Terminal block device with blocking function

Abstract

A terminal block device with a stopping function is used for inserting and connecting wires and includes: an insulating base, a slider, a spring, and a cam. The insulating base has a mating chamber and a socket and a groove respectively communicating with the mating chamber; the slider is slidably disposed in the groove and has a top pin and a claw; the spring is disposed in the mating chamber of the insulating base and has a wire clamping spring arm and a double-acting spring arm with an actuating section; the cam is rotatably connected to the insulating base in the mating chamber and has a raised section and a driven part with an actuating section. The slider slides in the groove by being pressed, so that the top pin pushes the wire clamping spring arm to swing and causes the claw to snap the actuating section; the wire is inserted into the socket and the mating chamber, pushing the raised section to disengage the actuating section from the claw, and also causing the wire clamping spring arm to elastically return to its swinging position and push back the top pin and elastically press the wire. This achieves the effect of inserting and removing wires without the need for tools and reduces structural complexity.

Claims

1. A terminal block device with a blocking function for inserting a wire and comprising: An insulating base has a mating chamber and is provided with a socket and a sliding groove, the socket and the sliding groove being respectively connected to the mating chamber; A slider, slidably inserted into the groove, having a top pin and a claw; a spring piece, disposed in the mating chamber on the insulating base, having a wire-clamping spring arm and a double-effect spring arm, both capable of elastically deflecting relative to the insulating base by force, the double-effect spring arm having an action section; and a cam, rotatably connected to the insulating base in the mating chamber, having a lifting section and a driven section, the action section being disposed in the driven section and capable of moving in conjunction with each other, the wire-clamping spring arm being correspondingly located between the top pin and the lifting section; By pressing the slider and sliding it within the groove, the top pin can push the wire clamping spring arm to swing in one direction, and the hook can also be flipped onto the action section. The wire is inserted into the docking chamber through the socket, which can push the raised section, causing the cam to rotate along with the driven part, thereby disengaging the action section from the hook. The wire clamping spring arm can also elastically reset and swing in the opposite direction, pushing back the top pin and elastically pressing the wire.

2. The terminal block device with a blocking function as described in claim 1, wherein the double-acting spring arm has a connecting section and the action section connected to each other, the action section being bent relative to the connecting section.

3. The terminal block device with a blocking function as described in claim 2, wherein the actuating section has at least two sides, one of which serves as a blocking portion, and the actuating section is used for the hook to be snapped back by the blocking portion.

4. The terminal block device with a blocking function as described in claim 1, wherein the spring also has a fixed spring arm, the fixed spring arm, the wire clamping spring arm and the double-effect spring arm are connected to each other, the fixed spring arm is positioned on the insulating seat, and the wire clamping spring arm and the double-effect spring arm can be elastically deflected relative to the fixed spring arm by force.

5. The terminal block device with a blocking function as described in claim 4, wherein the dual-effect spring arm is located between the wire clamping spring arm and the fixed spring arm.

6. The terminal block device with a blocking function as described in claim 4, wherein the clamping spring arm and the fixed spring arm have a first included angle, and the double-effect spring arm and the fixed spring arm have a second included angle, wherein the first included angle is greater than the second included angle.

7. The terminal block device with a blocking function as described in claim 4, wherein the spring sheet further has a first bending portion having one end and another end, the wire clamping spring arm is connected to the one end of the first bending portion, and the double-effect spring arm and the fixed spring arm are both connected to the other end of the first bending portion.

8. The terminal block device with a blocking function as described in claim 7, wherein the double-acting spring arm has a connecting section, a second bend and the action section connected to each other, the connecting section bridging between the other end of the first bend and a location of the second bend, and the action section connecting to the other location of the second bend and bending relative to the connecting section.

9. The terminal block device with a blocking function as described in claim 1, wherein the cam further has a body segment and a third bend, the third bend being connected between one end of the body segment and one end of the raised segment, the raised segment being bent relative to the body segment via the connection to the third bend, and the cam being rotatably connected to the insulating base at the other end of the body segment.

10. The terminal block device with a blocking function as described in claim 9, wherein the cam is provided with a driven part and a shaft connection part corresponding to one end and the other end of the body segment, respectively, and the cam is rotatably connected to the insulating seat via the shaft connection part.

11. The terminal block device with a blocking function as described in claim 10, wherein the insulating seat is provided with a shaft in the docking chamber, and the cam is rotatably connected to the shaft via the shaft connection.

12. The terminal block device with a blocking function as described in claim 1, wherein the insulating seat is provided with a shaft in the mating chamber, the cam is provided with a shaft connection portion, and the cam is rotatably connected to the shaft via the shaft connection portion.
