Abstract
Description
Technical Field
[0001] The invention relates to a terminal block, in particular to an easy-to-plug terminal block. Background Art
[0002] The current terminal block used to connect the circuit board and the signal line generally has a slidable clip set on the body of the terminal block, and the clip is used to clamp the edge of the circuit board inserted therein. When removing the terminal block, first slide the clip to separate the clip from the edge of the circuit board to separate the terminal block from the circuit board. However, the clip and the body are not fastened, so the circuit board is easy to shake. Therefore, a hook is provided to hook the circuit board, but in actual use, the hook is not easy to withdraw from the circuit board, making it difficult to remove the connector from the circuit board. Moreover, when the user pushes the clip to clamp the circuit board, it is impossible to know whether the circuit board is positioned.

DETAILED DESCRIPTION
[0023] See also Figures 1 to 4 A preferred embodiment of the present invention provides a terminal block, which includes an insulating seat 100, at least one elastic arm hook 200, and at least one slider 300 corresponding to the elastic arm hook 200. In this embodiment, the terminal block preferably includes a pair of identical elastic arm hooks 200 and a pair of opposite identical sliders 300, but the present invention does not limit the number of elastic arm hooks 200 and sliders 300.
[0024] In this embodiment, the insulating seat 100 is preferably a flat rectangular block, and the insulating seat 100 has a slot 101, at least one slide groove 102 corresponding to the slider 300, and a plurality of wiring holes 103. The opening of the slot 101 is slit-shaped, and a flat space is formed in the slot 101. In this embodiment, corresponding to the aforementioned pair of sliders 300, the insulating seat 100 preferably has a pair of slide grooves 102, but the present invention does not limit the number of slide grooves 102. The slide grooves 102 are arranged in a longitudinal direction 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 slot 101. The slot 101 is used to plug a circuit board 10, and each wiring hole 103 is used to plug a wire. In this embodiment, the insulating seat 100 is preferably provided with a plurality of terminals (not shown), and the terminals extend between the slot 101 and each wiring hole 103 to be used for connecting the circuit on the circuit board 10 so that the circuit board 10 is electrically connected to each wire.
[0025] The elastic arm hook 200 is fixed on the insulating seat 100 for buckling the circuit board 10. In this embodiment, the elastic arm hook 200 is preferably integrally formed with the insulating seat 100 and extends from the insulating seat 100. The elastic arm hook 200 is arranged with its longitudinal direction parallel to the depth direction of the slot 101. The cross section of the elastic arm hook 200 is generally rectangular. A first interference portion 210 and a hook portion 220 are protrudingly provided on one side surface of the elastic arm hook 200. The hook portion 220 vertically interferes with the extension plane of the slot 101. Therefore, when the circuit board 10 is inserted into the slot 101, the hook portion 220 can buckle into the corresponding buckle hole 11 of the circuit board 10 to lock the circuit board 10. During the process of inserting the circuit board 10 into the slot 101, the circuit board 10 pushes against the hook portion 220 to make the elastic arm hook 200 deflect and elastically deform; when the hook portion 220 can buckle 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 has been positioned. Moreover, the road plate is suppressed by the elastic arm hook 200 to prevent shaking.
[0026] The slider 300 is inserted into the slide groove 102 and is restricted between the insulating seat 100 and the elastic arm hook 200 so as to be able to move in the longitudinal direction of the slide groove 102. In this embodiment, the slider 300 is preferably in the shape of a plate, and the two side edges of the slider 300 are restricted by the slide groove 102 and the two sides of the slider 300 are respectively restricted by the insulating seat 100 and the elastic arm hook 200. Specifically, the slider 300 is attached to the other side of the elastic arm hook 200. The slider 300 has a second interference portion 320. Specifically, a flange 310 is convexly provided on one side of the slider 300 attached to the elastic arm hook 200 and the second interference portion 320 is arranged on one side of the flange 310 so as to interfere with the first interference portion 210.
[0027] See also Figures 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 that can abut the aforementioned slope, and the slope is inclined relative to the longitudinal direction of the elastic arm hook 200. When the slider 300 moves 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 lateral displacement of the elastic arm hook 200. Moreover, the freedom of the slider 300 in the lateral direction along the elastic arm hook 200 is fixed by the slide groove 102, the insulating seat 100 and the elastic arm hook 200, so all the relative lateral displacements between the slider 300 and the elastic arm hook 200 are located at the elastic arm hook 200, so that the elastic arm hook 200 can be deflected and the hook portion 220 can be withdrawn from the circuit board 10.
[0028] In this embodiment, the first interference portion 210 and the second interference portion 320 are preferably a pair of slopes attached to each other, so as to stabilize the displacement conversion action, but the present invention is not limited thereto.
[0029] See also Figures 4 to 8 In this embodiment, a handle 330 extends from the slider 300, and the extension direction of the handle 330 is opposite to the opening direction of the slot 101. Therefore, the user can pull the handle 330 to pull out the terminal block.
[0030] A stopper 110 is disposed in the slide slot 102 to stop the slider 300 from moving in a direction opposite to the opening of the slot 101 . In this embodiment, the stopper 110 has a stopper surface 111 for stopping the slider 300 , and the stopper surface 111 is disposed toward the opening of the slot 101 .
[0031] The moving direction of the slider 300 when releasing the elastic arm hook 200 matches the extending direction of the pull handle 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 the stop surface 111, the insulating seat 100 can be further pulled away from the circuit board 10. In this way, the user can release and remove the circuit board 10 at the same time by simply pulling the pull handle 330.
[0032] like Figure 6 As shown, when the hook portion 220 of the elastic arm hook 200 is buckled with the buckle hole 11 of the circuit board 10, the slider 300 simultaneously abuts against the edge of the circuit board 10 and further clamps and fixes the circuit board 10 by the hook portion 220 and the slider 300. In this 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 present invention is not limited thereto.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Other equivalent changes that apply the patent spirit of the present invention should all fall within the patent scope of the present invention.
