Detailed Description
Referring to fig. 1 to 4, a terminal block according to a preferred embodiment of the present invention includes an insulation base 100, at least one spring arm hook 200, and at least one slider 300 corresponding to the spring arm hook 200. In the present embodiment, the terminal block preferably includes a pair of identical spring arm hooks 200 and an opposite pair of identical sliders 300, however, the number of spring arm hooks 200 and sliders 300 is not limited by the present invention.
In this 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 slider 300, and a plurality of wire connecting 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 grooves 102 corresponding to the pair of sliding blocks 300, however, the number of sliding grooves 102 is not limited in the present invention. The slide groove 102 is disposed with its 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 socket 101 is used for plugging a circuit board 10, each of the wire connection holes 103 is used for plugging a wire, and in this embodiment, a plurality of terminals (not shown) are preferably disposed in the insulating base 100, and the terminals extend between the socket 101 and each of the wire connection holes 103 for interfacing with the circuit board 10 to electrically connect the circuit board 10 to each wire.
The spring arm hook 200 is fixed on the insulating base 100 for fastening the circuit board 10, in this embodiment, the spring arm hook 200 is preferably integrally formed with the insulating base 100 and extends from the insulating base 100. The arm hook 200 is disposed with its longitudinal direction parallel to the depth direction of the slot 101. The cross section of the spring arm hook 200 is approximately rectangular, a side surface of the spring arm hook 200 is provided with a first interference portion 210 and a hook portion 220 is convexly arranged, and the hook portion 220 is perpendicular to the extension plane of the slot 101. Therefore, when the circuit board 10 is inserted into the slot 101, the hook 220 can be snapped into the corresponding snap hole 11 of the circuit board 10 to lock the circuit board 10. When the circuit board 10 is inserted into the slot 101, the circuit board 10 pushes the hook 220 to deflect the spring arm hook 200 to elastically deform, and when the hook 220 can be buckled into the circuit board 10, the spring arm hook 200 rebounds to cause vibration, so that a user can know that the circuit board 10 is positioned. Furthermore, the road board is pressed by the spring arm hook 200 to avoid shaking.
The slider 300 is inserted into the slide slot 102 and is limited between the insulation seat 100 and the spring arm hook 200 so as to be capable of moving along the longitudinal direction of the slide slot 102. In the present embodiment, the slider 300 is preferably plate-shaped, two side edges of the slider 300 are limited by the sliding groove 102, and two sides of the slider 300 are limited by the insulating base 100 and the spring arm hook 200, respectively. Specifically, the slider 300 is attached to the other side of the spring arm hook 200. The slider 300 has a second interference portion 320, specifically, a flange 310 is protruding from a surface of the slider 300 attached to the arm hook 200, and the second interference portion 320 is disposed on one side of the flange 310 and is 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 configured to be inclined with respect to the longitudinal direction of the arm hook 200. When the slider 300 moves toward the bottom of the socket 101, the first interference portion 210 and the second interference portion 320 can push against each other to convert the longitudinal displacement of the slider 300 relative to the latch hook 200 into the lateral displacement of the latch hook 200. In addition, the degree of freedom of the slider 300 in the lateral direction along the arm hook 200 is fixed by the chute 102, the insulating base 100 and the arm hook 200, so that all the relative lateral displacement amounts between the slider 300 and the arm hook 200 are located at the arm hook 200, and the arm hook 200 can be deflected to retract the hook 220 from the circuit board 10.
In this embodiment, the first interference portion 210 and the second interference portion 320 are preferably a pair of slopes attached to each other. Therefore, the motion of displacement conversion is stable, but the invention is not limited to this.
Referring to fig. 4 to 8, in the present embodiment, the slider 300 extends out of a pull handle 330, 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 easily pull up the terminal block.
A stop 110 for stopping the movement of the slider 300 in a direction opposite to the opening direction of the slot 101 is provided inside the slide slot 102. In the present embodiment, the stop portion 110 has a stop surface 111 for stopping the slider 300, and the stop surface 111 is disposed toward the opening direction of the slot 101.
The moving direction of the slider 300 when releasing the spring arm hook 200 is matched with the extending direction of the pull handle 330, and is also opposite to the opening direction of the slot 101. Therefore, after the spring 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 pulled further to be separated from the circuit board 10. Thereby, the user can simultaneously release and detach the circuit board 10 by pulling the pull handle 330.
As shown in fig. 6, when the hook 220 of the spring arm hook 200 is fastened to the fastening hole 11 of the circuit board 10, the slider 300 is simultaneously abutted against the edge of the circuit board 10, and further the circuit board 10 is 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 220 of the spring 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 foregoing description of the preferred embodiments of the present invention is not intended to limit the scope of the invention, but rather to limit the scope of the invention to the equivalents of the claims to which the invention pertains.
