Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a high-precision IP54 grade waterproof switch. Background Art

[0002] Contact switches play a vital role in elevator systems. They are not only common consumables in elevator operation, but also occupy a pivotal position in the entire elevator safety circuit, ensuring that the elevator can operate safely in normal and emergency situations.

[0003] However, the contact switch in the prior art needs to be precisely aligned during the installation process, which places high demands on the technical level of the installation workers. Due to inaccurate alignment, the contact switch cannot work normally. In addition, in harsh environments, the contact switch may not be able to guarantee long-term stable working performance, resulting in negative effects.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0021] See also Figure 1 - Figure 3 Example 1 is described. The figure shows a high-precision IP54 waterproof switch, including a housing 10. A pin 1 is movably connected to the bottom of the housing 10. A forced disconnect mechanism 2 is embedded in the bottom of the inner cavity of the housing 10 and movably connected. A slider 3 is matched and connected to the top of the forced disconnect mechanism 2. Mounting screws 4 for mounting a cover plate are threadedly connected to the left and right sides of the housing 10. A moving contact 5 is connected to the top of the inner cavity of the housing 10. There are two moving contacts 5, and a static contact 7 is provided between the two moving contacts 5. A waterproof rubber plug 6 is connected to the edge of the top of the housing 10. A terminal screw 8 is provided on the side of the moving contact 5 away from the static contact 7. A spring member 9 is connected between the slider 3 and the static contact 7.

[0022] See also Figure 2 and Figure 4 The pin 1 shown in the figure adopts a cylindrical structure. The pin 1 drives the forced disconnection mechanism 2 to rotate, and the slider 3 moves back and forth in the housing 10 through the rotation of the forced disconnection mechanism 2;

[0023] In this embodiment, external force pushes the pin 1, and the forced disconnection mechanism 2 rotates accordingly, driving the slider 3 to move back and forth in the housing 10, thereby realizing the contact and disconnection between the moving contact 5 and the static contact 7. The static contact 7 contacts the moving contact 5 and is connected to the cable output by the wiring screw 8 to make the circuit conductive. The contact state between the moving contact 5 and the static contact 7 determines the on and off of the circuit, and the waterproof rubber plug 6 ensures the dryness and cleanliness of the inside of the housing 10, preventing pollutants such as water and dust from entering, thereby ensuring the stability and reliability of the switch in harsh environments. By installing the screws 4, the switch cover can be conveniently fixed to the housing 10 to protect the internal connection, and the wiring screws 8 are used to connect the external power line to ensure the stability and safety of the electrical connection. The function of the spring member 9 is to provide the necessary elastic force for the slider 3 to ensure that the moving contact 5 and the static contact 7 can be quickly separated when disconnected, reducing contact wear and extending the service life of the switch.

[0024] It should be noted that the pin 1 is inserted into the arc of the physical forced disconnection mechanism 2 by external force, and the slider 3 is pushed. The pin 1 is designed to be cylindrical, which improves the tolerance for left and right deviations and simplifies the installation process. It has better tolerance for left and right deviations than the old pin contacts, does not require very precise alignment for installation, and the tolerance for up and down deviation of the plug-in installation base is also improved. Example

[0025] See also Figure 1 and Figure 3 Example 2 is described. This embodiment further illustrates Example 1. In the figure, two movable contacts 5 are matched with the connection ends on the stationary contact 7. The stationary contact 7 maintains close contact with the movable contact 5 through the elastic force of the spring member 9.

[0026] Furthermore, the cable connected by the connection screws 8 is a multi-strand twisted wire, and the access method of the cable is a quick plug-in type.

[0027] In this embodiment, when the circuit needs to be disconnected, an external force acts on pin 1, causing the forced disconnection mechanism 2 to rotate, thereby driving the slider 3 to move. This action causes the static contact 7 to separate from the movable contact 5, completing the circuit disconnection. Under the action of external force, when pin 1 is pulled back, the forced disconnection mechanism 2 can ensure that the slider 3 is physically pulled back, thereby forcibly separating the movable contact 5 and the static contact 7 (this physical disconnection is one of the requirements of elevator safety standards).

[0028] It should be noted that the forced disconnection mechanism 2 ensures physical disconnection under the action of external force, which complies with elevator safety standards. The cable connected by the wiring screws 8 adopts multi-strand twisted wire to enhance the flexibility and tensile strength of the cable. The cable access method is quick plug-in type, which is convenient for maintenance and replacement, while ensuring the reliability of the electrical connection. Example

[0029] See also Figure 3 and Figure 4 Example 3 is described. This embodiment further illustrates Example 2. In the figure, two waterproof rubber plugs 6 are provided, and the two waterproof rubber plugs 6 match the two connecting screws 8.

[0030] Furthermore, a power outlet hole 11 is provided on the left side wall of the housing 10, and the power outlet hole 11 is made of rubber material;

[0031] In this embodiment, the power outlet hole 11 is made of a sealed rubber material to ensure waterproofness. After the product is installed and wired, the waterproof rubber plug 6 can be bent and pressed into the round hole of the wiring screw 8, making the entire product waterproof and sealed, reaching the product IP54 level, with high waterproof performance, which can ensure that the product can operate normally for a long time in more severe environments.

[0032] It should be noted that the waterproof rubber plug 6 effectively prevents the intrusion of water and other liquids, ensuring the normal operation of the switch in a humid or underwater environment. The material of the shell 10 is corrosion-resistant engineering plastic, which ensures the long-term stability and durability of the switch and ensures that the product reaches IP54 level of waterproof performance. This makes the high-precision IP54 waterproof switch not only improve the convenience of installation, but also maintains good working performance in harsh environments.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
