Referring to fig. 1 to 4, a terminal block according to a preferred embodiment of the present invention includes an insulating base 100, at least one elastic arm hook 200, and at least one slider 300 corresponding to the elastic arm hook 200. In the present embodiment, the terminal block preferably includes a pair of identical spring arm latches 200 and an opposite pair of identical sliders 300, however, the present invention is not limited to the number of spring arm latches 200 and sliders 300.

In the present embodiment, the insulating base 100 is preferably a flat rectangular block, and the insulating base 100 has a slot 101, at least one sliding slot 102 corresponding to the sliding block 300, and a plurality of wire holes 103. The opening of the slot 101 is slit-shaped, and a flat space is formed in the slot 101. In the present embodiment, the insulating base 100 preferably has a pair of sliding slots 102 corresponding to the pair of sliding blocks 300, however, the present invention is not limited to the number of sliding slots 102. The slide groove 102 is disposed in a longitudinal direction thereof parallel to the depth direction of the slot 101. The opening direction of each wiring hole 103 is opposite to the opening direction of the socket 101. The slot 101 is used for inserting a circuit board 10, and each of the wiring holes 103 is used for inserting a wire, in the embodiment, a plurality of terminals (not shown) are preferably disposed in the insulating base 100, and the terminals extend between the slot 101 and each of the wiring holes 103 for electrically connecting the circuit board 10 to the wires by butting the circuit on the circuit board 10.

The elastic arm hook 200 is fixed to the insulating base 100 for fastening the circuit board 10, and in this embodiment, the elastic arm hook 200 is preferably integrally formed with the insulating base 100 and extends from the insulating base 100. The elastic arm hook 200 is disposed with its longitudinal direction parallel to the depth direction of the slot 101. The elastic arm hook 200 has a rectangular cross section, and a first interference portion 210 and a protruding hook portion 220 are disposed on a side surface of the elastic arm hook 200, and the hook portion 220 vertically interferes with the extending plane of the slot 101. Therefore, when the circuit board 10 is inserted into the slot 101, the hook 220 can be locked to the circuit board 10 by being locked into the corresponding fastening hole 11 of the circuit board 10. When the circuit board 10 is inserted into the slot 101, the circuit board 10 pushes the hook 220 to make the elastic arm hook 200 swing and deform elastically; when the hook 220 can be fastened into the circuit board 10, the elastic arm hook 200 rebounds to cause vibration, so that the user can know that the circuit board 10 is positioned. Furthermore, the circuit board is pressed by the elastic arm hook 200 to be free from shaking.

The slider 300 is inserted into the sliding slot 102 and is constrained between the insulating base 100 and the elastic arm hook 200 to be able to move along the longitudinal direction of the sliding slot 102. In the present embodiment, the slider 300 is preferably in a plate shape, two side edges of the slider 300 are limited by the sliding slot 102, and two sides of the slider 300 are limited by the insulating base 100 and the elastic arm hook 200, respectively. Specifically, the slider 300 is attached to the other side surface of the elastic arm hook 200. The slider 300 has a second interference portion 320, specifically, a flange 310 is protruded from a surface of the slider 300 attached to the elastic arm hook 200, and the second interference portion 320 is disposed at a side of the flange 310 to be capable of interfering with the first interference portion 210.

Referring to fig. 5 to 8, in the simplest embodiment, at least one of the first interference portion 210 and the second interference portion 320 is a slope, and the other is any structure capable of abutting against the slope, and the slope is disposed obliquely with respect to the longitudinal direction of the elastic arm hook 200. During the stroke of the slider 300 moving toward the bottom of the slot 101, the first interference portion 210 and the second interference portion 320 can push each other to convert the longitudinal displacement of the slider 300 relative to the elastic arm hook 200 into the transverse displacement of the elastic arm hook 200. Furthermore, the slider 300 is fixed by the sliding slot 102, the insulating base 100 and the elastic arm hook 200 along the lateral freedom of the elastic arm hook 200, so that all the relative lateral displacements between the slider 300 and the elastic arm hook 200 are located at the elastic arm hook 200, and the elastic arm hook 200 can swing to make the hook 220 move away from the circuit board 10.

In the present embodiment, the first interference portion 210 and the second interference portion 320 are preferably a pair of slopes attached to each other. Thereby, the movement of the displacement conversion is stable, however, the present invention is not limited thereto.

Referring to fig. 4 to 8, in the embodiment, a pull handle 330 extends from the slider 300, and the extending direction of the pull handle 330 is opposite to the opening direction of the slot 101. The user can pull the pull handle 330 to facilitate pulling up the terminal block.

A stopping portion 110 for stopping the sliding block 300 from moving in a direction opposite to the opening direction of the slot 101 is disposed in the sliding groove 102. In the present embodiment, the stopping portion 110 has a stopping surface 111 for stopping the slider 300, and the stopping surface 111 is disposed toward the opening direction of the slot 101.

The moving direction of the slider 300 when releasing the elastic arm hook 200 is matched with the extending direction of the pull tab 330, which is also opposite to the opening direction of the slot 101. Therefore, after the elastic arm hook 200 is pushed away from the circuit board 10 by the slider 300, the user can continue to pull the pull handle 330, and after the slider 300 moves to abut against the stop surface 111, the insulating base 100 can be further pulled away from the circuit board 10. Therefore, the user can release and detach the circuit board 10 at the same time by pulling the pull handle 330.

As shown in fig. 6, when the hook 220 of the elastic arm hook 200 is fastened to the fastening hole 11 of the circuit board 10, the slider 300 abuts against the edge of the circuit board 10 at the same time, and the circuit board 10 is further clamped and fixed by the hook 220 and the slider 300. In the present embodiment, the circuit board 10 is preferably clamped by the hook portion 220 of the elastic arm hook 200 and the flange 310 of the slider 300, thereby positioning the circuit board 10 along the depth direction of the slot 101, but the invention is not limited thereto.

The above only preferred embodiments of the present invention are described, not to limit the scope of the present invention, other applications the equivalent changes of the patent spirit of the present invention should be all included in the scope of the present invention.
