Technical Field
[0001] The utility model relates to the technical field of switch equipment, in particular to a waterproof push button switch. Background Art
[0002] With the continuous development of science and technology, electronic equipment and electrical systems have been widely used in various fields. In these systems, push button switches are a common control element used to realize the opening and closing of circuits or the transmission of signals. However, in humid or flooded environments, traditional push button switches often have insufficient waterproof performance, resulting in circuit short circuits, equipment damage and even safety hazards. They also have complex structures and high costs. Utility Model Content
[0003] In view of this, the purpose of the utility model is to provide a waterproof push button switch with simple structure, low cost and good protection performance.
[0004] In order to achieve the above purpose, the utility model adopts such a waterproof push button switch, including a bottom shell and a static contact piece connected to the bottom shell, the bottom shell is formed with an opening upward, a turntable is arranged in the opening, a guide column is protruding from the turntable, a through hole is opened on the guide column, the through hole passes through the guide column and extends to the inside of the turntable, a spring sheet is arranged between the turntable and the static contact piece, the spring sheet is connected to the bottom shell, a button is arranged in the through hole, and a waterproof cover is provided on the button.
[0005] The working principle of the utility model is as follows: under normal conditions, the spring piece maintains a certain distance from the circular static contact on the first static contact piece, and the circuit is in a disconnected state. When the button is pressed, the pressing portion is forced to move downward, driving the action portion and the hole axis inside it to slide downward along the through hole of the guide column. At this time, the spring on the guide column is compressed and stores elastic potential energy. As the button is further pressed, the spring piece is squeezed by the hole axis and deformed, and finally contacts the circular static contact on the first static contact piece to form an electrical connection, so that the circuit is energized. When the external force is removed, the spring releases the stored elastic potential energy, pushing the guide column to move upward. The spring piece returns to its original state due to the loss of external force, disengages from the static contact piece, and the circuit is disconnected again. In the process of disengaging the spring piece from the static contact piece, due to the elastic effect of the spring piece, a certain stroke will be maintained. The beneficial effects of the above structure are: by adopting a modular design, the overall structure of the waterproof push button switch is made more compact and simple, and the production cost is reduced and the production efficiency is improved. By arranging a waterproof cover on the button, water and moisture are effectively prevented from entering the inside of the push button switch, thereby ensuring the stability and safety of the circuit. The design of the spring piece enables the switch to accurately control the on and off of the circuit, ensuring that the circuit can be reliably closed when needed and can be quickly disconnected when not needed. In the process of the spring piece being disengaged from the static contact piece, due to the elastic effect of the spring piece, a certain stroke will be maintained, which helps to prevent the switch from being accidentally triggered under the influence of external factors such as vibration or impact, thereby improving the stability and safety of the switch.
[0006] The utility model is further configured such that the button includes a pressing part and an action part, the action part is downwardly formed with a travel cavity, the travel cavity is provided with a hole shaft for inserting a through hole, the upper part of the guide column is wound with a spring, the spring extends upward, one end of the spring presses against the turntable, and the other end presses against the top of the travel cavity. The spring wound on the upper part of the guide column not only provides the necessary resilience for the button, but also ensures the stability of the button during operation, one end of the spring presses against the turntable, and the other end presses against the top of the travel cavity, ensuring that the spring can be evenly distributed when subjected to force, further improving the stability and reliability of the button.
[0007] The utility model is further configured that the waterproof cover includes a cover body and a skirt arranged on the outer periphery of the cover body, the skirt is installed on the bottom shell, and a pressing plate is also arranged on the upper end of the skirt, the cover body extends to the outside through the pressing plate, and the pressing plate is clamped on the bottom shell. The close fit between the skirt and the bottom shell and the clamping design of the pressing plate ensure the stability of the waterproof cover during use.
[0008] The utility model is further configured that a groove is provided at the connection between the action part and the pressing part of the button, and the action part and the groove of the button are both arranged in the cover body, and the pressing part extends to the outside through the cover body. The action part and the groove are arranged in the cover body, and the cover body is used as a physical barrier to effectively prevent water and moisture from directly contacting the internal structure of the button, thereby improving the waterproof performance.
[0009] The utility model is further configured that both sides of the bottom shell are provided with guide protrusions, both sides of the pressure plate are provided with guide groove plates matching with the guide protrusions, the guide groove plates are clamped on the guide protrusions, both ends of the pressure plate are also provided with handles, and both ends of the bottom shell are provided with avoidance grooves corresponding to the handles. The close cooperation between the guide protrusions and the guide groove plates ensures a stable connection between the pressure plate and the bottom shell, effectively preventing loosening or falling off due to vibration or impact during use. The handle design at both ends of the pressure plate enables the user to easily pull the pressure plate out of the bottom shell through the handles when the pressure plate needs to be disassembled for maintenance or replacement, without the need to use special tools or complicated operations, thereby improving the maintainability of the product.
[0010] The utility model is further configured that the static contact piece includes a first static contact piece and a second static contact piece arranged at the bottom of the opening, the first static contact piece is formed with a circular static contact point, the circular static contact point is located directly below the spring piece, and the second static contact piece is formed with two elongated static contacts, the elongated static contacts are respectively located on both sides of the circular static contact. The circular static contact on the first static contact piece is located directly below the spring piece, ensuring that the spring piece can accurately contact or separate with the static contact point when in motion, thereby realizing the electrical connection or disconnection of the switch, and the two elongated static contacts on the second static contact piece are respectively located on both sides of the circular static contact, and this layout provides additional electrical connection points, thereby increasing the stability and reliability of the switch.
