[0059] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0060] Please refer to Figures 1 to 6 As shown, the present invention provides a terminal block with a handle. The terminal block 10 mainly includes an insulating seat 1, a conductive terminal 2, a clamp spring 3 and a turning member 4.

[0061] like Figure 1 , Figures 4 to 6 As shown, the insulating seat 1 has a cavity 11 inside and a slot 12 communicating with the cavity 11 outside, and a limiting column 111 extends from the inner wall of the cavity 11 .

[0062] The details are as follows. The insulating seat 1 also has a front wall 13 and a top wall 14. The front wall 13 has a through slot 131 connected to the cavity 11. Two pivots 133 extend from the inner wall of the through slot 131. The slot 12 of this embodiment is formed from the top wall 14, but this is not limiting.

[0063] In addition, the front wall 13 protrudes outward to form an outer protruding piece 132 . The outer protruding piece 132 is provided with an arc-shaped guide groove 15 . The arc-shaped guide groove 15 has two end portions 151 and two protruding points 152 extending from the inner wall and disposed on one side of each end portion 151 .

[0064] like Figure 1 , Figures 4 to 6As shown, the conductive terminal 2 is fixed at the bottom of the slot 12 . The conductive terminal 2 has a latching portion 21 . The latching portion 21 of this embodiment is a latching groove 211 , but the present invention is not limited thereto.

[0065] like Figure 1 , Figures 4 to 6 As shown, the clamp spring piece 3 is accommodated in the cavity 11 and disposed above the conductive terminal 2 . The clamp spring piece 3 extends to have a movable elastic arm 31 that abuts against the conductive terminal 2 and closes the slot 12 .

[0066] As further described below, the clamp spring piece 3 is a U-shaped spring piece 30, a movable spring arm 31 is formed at one end of the U-shaped spring piece 30, a positioning spring wall 32 is formed at the other end, and a bending section 33 is formed in the middle. The end of the positioning spring wall 32 is passed through and engaged with the groove 211, so that the end of the positioning spring wall 32 is engaged with the latch portion 21, and the bending section 33 is sleeved on the outside of the limiting column 111.

[0067] like Figures 1 to 6 As shown, the pull member 4 is installed on the insulating seat 1, and the pull member 4 has a rotating shaft 41 pivoted to the cavity 11. The rotating shaft 41 protrudes outward from the outer periphery to have a pressing block 42 abutting against the movable elastic arm 31, and the pressing block 42 is arranged above the movable elastic arm 31. The rotating shaft 41 is provided with two pivot holes 411 pivoted to the two pivots 133, so that the rotating shaft 41 can be pivoted at the two pivot holes 411.

[0068] The details are as follows. The turning member 4 is accommodated in the through slot 131 . The turning member 4 has a handle 44 exposed on the front wall 13 . The turning member 4 has a convex column 45 that passes through and slides in the arc-shaped guide slot 15 . Each convex point 152 can be engaged with the convex column 45 .

[0069] In addition, the turning member 4 rotates between a locking position and a releasing position. When the user turns the handle 44 of the turning member 4 to the releasing position, the turning member 4 drives the pressing block 42 to swing around the rotating shaft 41 to press the movable elastic arm 31, thereby moving the movable elastic arm 31 away from the conductive terminal 2 and opening the slot 12.

[0070] Furthermore, when the user rotates the handle 44 of the rotating member 4 to the locking position, the movable elastic arm 31 is not pressed by the pressing block 42 , so that the movable elastic arm 31 is restored to the position of abutting against the conductive terminal 2 and closing the slot 12 .

[0071] In addition, the turning member 4 has a connecting rod 43, and a handle 44 and a rotating shaft 41 are respectively extended from both ends of one side of the connecting rod 43. The U-shaped spring piece 30 is arranged on the inner side of the connecting rod 43, the handle 44 and the rotating shaft 41; therefore, when the turning member 4 rotates between the locking position and the releasing position, the connecting rod 43, the handle 44 and the rotating shaft 41 will move on one side of the U-shaped spring piece 30 without colliding with the U-shaped spring piece 30, and only the pressing block 42 will abut against the movable spring arm 31.

[0072] like Figures 4 to 6 FIG. 1 shows the use state of the terminal block 10 of the present invention. First, Figures 4 to 5 As shown, the user rotates the handle 44 of the pull member 4 to the locking position, and the movable elastic arm 31 is not pressed by the pressing block 42, so that the movable elastic arm 31 is reset to the position of abutting the conductive terminal 2 and closing the slot 12. At this time, the wire 100 cannot be inserted into the slot 12; Figure 6 As shown, when the wire 100 needs to be installed in the slot 12, the user rotates the handle 44 of the turning member 4 to the release position, and the turning member 4 drives the pressing block 42 to swing around the rotating shaft 41 to press the movable elastic arm 31, so that the movable elastic arm 31 is away from the conductive terminal 2 and the slot 12 is opened. At this time, the wire 100 can be inserted into the slot 12; finally, the turning member 4 is released, and the movable elastic arm 31 will reset in the direction close to the conductive terminal 2 until the movable elastic arm 31 presses against the core wire 101 of the wire 100 and touches the conductive terminal 2, that is, the movable elastic arm 31 and the conductive terminal 2 jointly clamp the core wire 101 of the wire 100, so that the wire 100 and the conductive terminal 2 are electrically connected to each other.

[0073] Thus, compared with the conventional method of using a screwdriver or other tools to press the spring piece, the present invention rotates the rotating member 4 to drive the movable spring arm 31 to open the slot 12, close the slot 12, or press against the core wire 101 of the wire 100 to electrically connect the conductive terminal 2, thereby eliminating the need for a screwdriver or other tools to meet the needs of quickly disconnecting the wire 100, thereby improving the customer's usage efficiency.

[0074] In addition, if Figure 6 As shown, when the turning member 4 of the present embodiment is rotated to the release position, the pressing block 42 swings to a horizontal state with the rotating shaft 41 as the center and presses the movable elastic arm 31. At this time, because the force direction applied by the pressing block 42 to the movable elastic arm 31 is parallel to and offsets the elastic restoring force direction of the movable elastic arm 31, the pressing block 42 and the movable elastic arm 31 will lock with each other and automatically stop moving, thereby eliminating the action of keeping the handle 44 pressed and achieving the purpose of tool-free wiring.

[0075] Furthermore, the lever 4 extends with a boss 45 that passes through and slides in the arc guide groove 15. When the user rotates the handle 44 of the lever 4 to the locking position and the releasing position, the boss 45 will slide over the protrusion 152 to produce a locking feeling. Finally, the boss 45 will be embedded in the end 151 and stopped by the protrusion 152, so that the boss 45 is engaged by the protrusion 152 and temporarily positioned.

[0076] In addition, if Figure 1 , Figure 4 As shown, the terminal block 10 of the present invention can be connected to each other in multiple groups, and multiple insulating seats 1 are combined together using a concave-convex structure to achieve the purpose of multiple slots 12 and conductive terminals 2 providing multiple wires 100 for connection.

[0077] Please refer to Figures 7 and 8 FIG. 1 is another embodiment of the terminal block 10 of the present invention. Figures 7 and 8 Examples and Figures 1 to 6 The embodiments are roughly the same, Figures 7 and 8 Examples and Figures 1 to 6 The embodiment of the present invention is different in that the structures of the slot 12, the latch portion 21, the rotating member 4 and the bending section 33 are different.

[0078] Further explanation is as follows: the slot 12 of this embodiment is formed by opening from the front wall 13, and the latch portion 21 is a stopper 212, but this is not limiting. The end of the positioning spring wall 32 is stopped and limited by the stopper 212 so that the end of the positioning spring wall 32 is engaged with the latch portion 21.

[0079] In addition, the two ends of the connecting rod 43 of this embodiment are extended with handles 44 and a rotating shaft 41, and the bending section 33 is provided with a U-shaped opening 331, and the connecting rod 43 can be inserted into the U-shaped opening 331; therefore, when the pull member 4 rotates between the locking position and the releasing position, the connecting rod 43 will move inside the U-shaped opening 331 without colliding with the U-shaped spring piece 30, and the handle 44 and the rotating shaft 41 will move outside the U-shaped spring piece 30 without colliding with the U-shaped spring piece 30, and only the pressing block 42 will abut against the movable spring arm 31. In this way, the same as Figures 1 to 6 The functions and effects of the embodiments.

[0080] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
