Description

Technical Field

[0001] The utility model relates to the field of electronic switches, in particular to a novel vibration switch. Background Art

[0002] A vibration switch, also known as a vibration switch sensor, is an electronic switch that senses vibration force and transmits the result to a circuit device, activating the circuit. Existing vibration switches use glue to bond the circuit boards together. However, glue bonding is difficult to control: too much glue can overflow, while too little can result in a loose, non-waterproof bond. This approach requires very high precision and is slow to assemble. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a new vibration switch that replaces the glue bonding structure. The specific technical solution is as follows:

[0004] A novel vibration switch comprises an upper circuit board, an upper PP sheet, a spring, a middle PP sheet, a middle circuit board, a lower PP sheet and a lower circuit board. The bottom of the upper circuit board is attached to the surface of the upper PP sheet, the bottom of the upper PP sheet is attached to the surface of the spring, the bottom of the spring is attached to the surface of the middle PP sheet, the bottom of the middle PP sheet is attached to the surface of the middle circuit board, the bottom of the middle circuit board is attached to the surface of the lower PP sheet, and the bottom of the lower PP sheet is attached to the surface of the lower circuit board. The upper PP sheet, the middle PP sheet and the lower PP sheet will soften when heated and pressurized and will solidify after cooling. The upper circuit board is attached to the spring via the upper PP sheet, the spring is attached to the middle circuit board via the middle PP sheet, and the middle circuit board is attached to the lower circuit board via the lower PP sheet.

[0005] As a preferred solution of the present invention, the upper PP sheet is provided with a first through hole, the middle PP sheet is provided with a second through hole, the middle circuit board is provided with a third through hole, and the lower PP sheet is provided with a fourth through hole. The positions of the first through hole, the second through hole, the third through hole, and the fourth through hole are correspondingly superimposed to form a shrapnel space. A spring sheet is provided on the inside of the shrapnel, and the spring sheet is placed in the shrapnel space.

[0006] As a preferred solution of the present invention, the vibration switch is installed horizontally, and the spring piece is easily triggered to shift when it moves up and down, but is not easily shifted when it moves forward, backward, left, and right.

[0007] As a preferred solution of the present invention, the temperature resistance is -20 degrees to 70 degrees.

[0008] As a preferred solution of the present invention, two solder pads are provided at the bottom of the lower circuit board.

[0009] Beneficial effect: The new vibration switch of the utility model adopts a brand-new bonding structure. The upper PP sheet, the middle PP sheet and the lower PP sheet will soften when heated and pressurized and will solidify after cooling. In this way, the upper circuit board, the upper PP sheet, the spring piece, the middle PP sheet, the middle circuit board, the lower PP sheet and the lower circuit board are all stacked together and then heated and pressurized. The upper circuit board can be connected to the spring piece through the upper PP sheet; the spring piece is connected to the middle circuit board through the middle PP sheet; the middle circuit board is connected to the lower circuit board through the lower PP sheet. The various layers of the switch are firmly and waterproofly pasted, the processing is convenient and quick, the practicability is strong, and it meets the production requirements.

[0015] The following is a further description of the specific embodiments of the present invention with reference to the accompanying drawings:

[0016] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0018] like Figures 1 to 3As shown, a new type of vibration switch includes an upper circuit board 1, an upper PP sheet 2, a spring 3, a middle PP sheet 4, a middle circuit board 5, a lower PP sheet 6 and a lower circuit board 7. The bottom of the upper circuit board 1 is attached to the surface of the upper PP sheet 2, the bottom of the upper PP sheet 2 is attached to the surface of the spring 3, the bottom of the spring 3 is attached to the surface of the middle PP sheet 4, the bottom of the middle PP sheet 4 is attached to the surface of the middle circuit board 5, the bottom of the middle circuit board 5 is attached to the surface of the lower PP sheet 6, and the bottom of the lower PP sheet 6 is attached to the surface of the lower circuit board 7. The upper circuit board 1 is attached to the spring through the upper PP sheet 2, the spring 3 is attached to the middle circuit board 5 through the middle PP sheet 4, and the middle circuit board 5 is attached to the lower circuit board 7 through the lower PP sheet 6.

[0019] PP sheets, also known as prepregs, are primarily composed of resin and reinforcement materials. Reinforcement materials can be categorized into fiberglass cloth, paper-based, and composite materials. The prepregs (bonding sheets) used in multilayer printed circuit boards are mostly reinforced with fiberglass cloth. This treated fiberglass cloth is then impregnated with a resin adhesive and heat-treated (pre-baked) to bring the resin to its B-stage. The resulting sheet material is called prepreg. It softens under heat and pressure and solidifies upon cooling. From bottom to top, the upper circuit board (1), upper PP sheet (2), spring element (3), middle PP sheet (4), middle circuit board (5), lower PP sheet (6), and lower circuit board (7) are placed in the positioning mold. The upper, middle, and lower PP sheets (2, 4, and 6) soften under heat and pressure and solidify upon cooling, thus bonding the layers together.

[0020] Specifically, the upper PP sheet 2 is provided with a first through hole 2a, the middle PP sheet 4 is provided with a second through hole 4a, the middle circuit board 5 is provided with a third through hole 5a, and the lower PP sheet 6 is provided with a fourth through hole 6a. The first through hole 2a, the second through hole 4a, the third through hole 5a, and the fourth through hole 6a are correspondingly superimposed to form a shrapnel space. A spring sheet 3a is provided on the inside of the shrapnel 3, and the spring sheet 3a is placed in the shrapnel space. In this way, the PP sheet will not affect the vibration of the spring sheet 3a, and can ensure that the PP sheet seals the outside and has good waterproof performance.

[0021] like Figure 4 As shown, the vibration switch is installed horizontally. When it moves up and down, it is easy to trigger the spring piece 3a to shift, thereby turning on the internal circuit of the switch. When it moves forward, backward, left and right, the spring piece 3a is not easy to shift up and down. In addition, the vibration switch has a temperature resistance of -20 degrees to 70 degrees. Two solder pads are provided at the bottom of the lower circuit board 7, which can be used to install the vibration switch horizontally.

[0022] Specifically, such as Figure 5 As shown, multiple lower circuit boards 7 can be placed into the jig for positioning first, and then the positioning sleeves are installed. Multiple lower PP sheets 6, middle circuit boards 5, middle PP sheets 4, springs 3, upper PP sheets 2, and upper circuit boards 1 are stacked in sequence, and then baked, heated, and pressed. The PP sheets will soften under heating and pressure, and will react and solidify after cooling. Multiple products can be produced by cutting at one time.

[0023] The above content is a further detailed description of the present invention in combination with specific preferred implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or replacements without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
