Description

Technical Field

[0001] The utility model relates to a switch, in particular to a long-stroke sealed switch with high insulation performance. Background Art

[0002] A switch is an electrical component used to control the flow of current in a circuit. The switch usually includes a housing, a button, an electrical connector and a moving contact piece. The moving contact piece is displaced by operating the button, so that the moving contact piece contacts or separates from the electrical connector to close or disconnect the circuit. There are many types of switches, which can be divided into many types according to their uses, operating methods, structures and application environments. For example, a long-stroke sealed switch with high insulation performance is commonly used in the fields of home appliances, automobiles and ships. The switch is often required to maintain stable operation in harsh environments, and has high requirements for sealing and durability. However, the long-stroke sealed switch with high insulation performance in the prior art mainly uses an elastic structure. When the button is operated, the elastic structure jumps to form the operation of the moving contact piece. This makes the switch accidentally turned on and off due to external vibration when used in equipment such as washing machines, which has stability problems and is also prone to damage to the equipment, affecting the user's experience.

[0005] The advantages of adopting the above technical solution are: an action piece is set in the shell, and the action piece is allowed to slide vertically with the button, and the moving contact piece is clamped on the action piece, so that the moving contact piece can slide vertically with the button through the action, and the first electrical connector is set at a position close to the action piece and the first electrical connector is allowed to be on the movement path of the front end of the moving contact piece corresponding to it, so that when the button is operated, the vertical displacement of the moving contact piece can be changed to form or release the release with the first electrical connector. This ensures that even if the device is operated in an environment with large external vibration, the moving contact piece will not accidentally form or release contact with the first electrical connector due to vibration. The device has stronger stability, avoids affecting the safety of the device, and provides a better experience for users.

[0006] The utility model can be further configured as follows: the front end of the movable contact piece is provided with an arc portion for forming an abutment fit with the first electrical connector.

[0007] By further arranging an arc portion at the front end of the moving contact piece, the arc portion contacts the first connecting member, thereby reducing the wear caused by the moving contact piece and the first electrical connecting member when they cooperate, thereby ensuring the service life of the product.

[0008] The utility model can be further configured as follows: comprising a second electrical connector, a through slot for the first electrical connector to pass through is opened in the middle of the actuating member, the second electrical connector is inserted into the actuating member, and the second electrical connector is arranged around the through slot, and the plurality of movable contact pieces are formed by extending from the second electrical connector.

[0009] Through further configuration, a second electrical connector is provided which is inserted into the actuating member, and a plurality of moving contact pieces are formed by extending from the second electrical connector, which facilitates installation. A through groove is provided in the actuating member for the first electrical connector to pass through, and the second electrical connector is arranged around the through groove, so as to facilitate the cooperation between the moving contact piece and the first electrical connector.

[0010] The utility model can be further configured as follows: movable contact pieces are extendedly provided on both sides of the second electrical connector corresponding to the first electrical connector.

[0011] Through further configuration, movable contact pieces are extended and arranged on both sides of the second electrical connector corresponding to the first electrical connector, so that the movable contact piece can be clamped on the first electrical connector, further ensuring stability during operation.

[0012] The utility model can be further configured as follows: a guide column is arranged in the shell, and a cylinder portion which is slidably sleeved on the guide column is arranged at the lower end of the button.

[0013] Through further configuration, a guide column is provided in the shell, and a cylinder portion slidably sleeved on the guide column is provided at the lower end of the button, so as to further limit the movement direction of the button and ensure the stability of the product.

[0014] The utility model can be further configured as follows: a cap portion and a silicone sleeve are provided on the button, the upper end of the silicone sleeve is embedded under the cap portion, and the lower end of the silicone sleeve covers the connection hole between the button and the housing.

[0015] Through further configuration, a cap and a silicone sleeve are provided on the button, and the silicone sleeve is used to cover the connection between the button and the shell to enhance the waterproof ability. The silicone sleeve is embedded under the cap, so that the cap can cover the connection between the silicone sleeve and the button to further enhance the waterproof ability.

[0016] The utility model can be further configured as follows: a first retaining ring and a second retaining ring are arranged on the shell, the first retaining ring is formed by extending from the edge of the connecting hole of the shell, and the silicone sleeve is sleeved on the outside of the first retaining ring, and the second retaining ring is arranged around the silicone sleeve.

[0017] Through further configuration, a first retaining ring and a second retaining ring are provided on the shell, wherein the first retaining ring is sleeved with the silicone sleeve, and the second retaining ring is provided around the silicone sleeve, thereby further enhancing the waterproof performance.
