Description

Technical Field

[0001] The utility model relates to the technical field of switch structures, in particular to a waterproof sealed switch. Background Art

[0002] At present, sealed switches are commonly used in ships or places that are frequently exposed to external water sources. They are used in harsh environments such as strong vibration, large impact, low temperature, outdoor rainy days and seaside to play a role in signal transmission.

[0003] During actual use, the gaps between the upper cover and base of the sealed switch, between the plug and the upper cover, and between the contacts and the switch may become potential factors for rainwater to penetrate. In actual use, once these places leak, it will cause product malfunction and failure, rendering the product unusable, and fail to meet the actual application requirements for reliability in rainy and humid environments. Therefore, in response to the above problems, our company has made improvements. Utility Model Content

[0004] The purpose of this utility model is to address the above problems and provide a waterproof sealed switch. A sealing ring is provided between the switch base and the switch cover, and a sealing sleeve is designed at the contact position. As the contacts are squeezed, the sealing sleeve can still play a sealing effect, ensuring that rainwater cannot enter the interior of the switch, thereby achieving the function of rainproof.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A waterproof sealed switch includes a switch base and a switch cover that match each other. Terminals are arranged in the internal cavity structure formed by the switch base and the switch cover. Contacts are movably arranged on the sides of the switch base and the switch cover. A compression spring is arranged between one end of the contact and the terminal. A sealing ring is arranged on the mating surface between the switch base and the switch cover. A sealing sheath is arranged on the outside of the contact and at a position where one end of the switch base and the switch cover does not extend out. Sealant is provided at the position where the terminal extends out from the upper end of the switch cover.

[0007] As a further improvement of the above solution, a groove for accommodating a compression spring is provided on the bottom of the contact facing the terminal post.

[0008] As a further improvement of the above solution, a mounting rod for placing a compression spring is provided on the side of the terminal facing the contact.

[0009] As a further improvement of the above solution, the sealing sleeve is in the shape of an arc-shaped sleeve structure, and when the contact is pressed toward the switch base and the switch cover, it has a sealing effect on the position of the gap.

[0010] As a further improvement of the above solution, the sealant is an adaptive structure generated by filling the sealant grooves at the upper ends of the terminal posts and the switch cover.

[0011] As a further improvement of the above solution, the sealing ring is extruded and deformed and arranged between the switch base and the switch cover, and fills the gap between the switch base and the switch cover.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] A sealing ring is set between the switch base and the switch cover, and a sealing cover is designed at the contact position. As the contacts are squeezed, the sealing cover can still play a sealing effect, ensuring that rainwater cannot enter the inside of the switch, thereby achieving the function of rainproof.

[0020] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, the specific scheme of this embodiment is: a waterproof sealed switch, including a switch base 8 and a switch cover 6 that match each other, a terminal 4 is arranged in the internal cavity structure formed by the switch base 8 and the switch cover 6, a contact 1 is movably arranged on the side of the switch base 8 and the switch cover 6, a compression spring 3 is arranged between one end of the contact 1 and the terminal 4, a sealing ring 5 is arranged on the mating surface between the switch base 8 and the switch cover 6, a sealing sheath 2 is arranged on the outside of the contact 1 and at a position where one end of the switch base 8 and the switch cover 6 does not extend out, and a sealant 7 is provided at the position where the terminal 4 extends from the upper end of the switch cover 6.

[0022] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a groove for accommodating the compression spring 3 is provided at the bottom of the contact 1 facing the terminal 4 .

[0023] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a mounting rod for placing the compression spring 3 is provided on the side of the terminal 4 facing the contact 1 .

[0024] like Figure 1 As shown, as a preferred embodiment of the above embodiment, the sealing sleeve 2 is in the shape of an arc-shaped sleeve structure, and the contact 1 plays a sealing role at the position of the gap when pressed toward the switch base 8 and the switch cover 6.

[0025] like Figure 1 As shown, as a preferred embodiment of the above embodiment, the sealant 7 is an adaptive structure formed by filling the sealant grooves at the upper ends of the terminal 4 and the switch cover 6 by potting.

[0026] like Figure 1 As shown, as a preferred embodiment of the above embodiment, the sealing ring 5 is extruded and deformed and arranged between the switch base 8 and the switch cover 6, and fills the gap between the switch base 8 and the switch cover 6.

[0027] The specific working principle of this utility model:

[0028] During specific use, the terminal 4 and contact 1 inside the switch are connected inside the switch body by a compression spring 3. The two terminal 4 of the switch are connected and conductive by a wire. When working, a conductor outside the switch moves laterally and presses the two contacts 1 to the surface of the switch housing (pressing them to the switch surface is to make the contact between the conductor and the contact 1 more secure), thereby achieving connection.

[0029] 1. Compared with previous products, this application provides a sealing ring 5 on the mating surface between the switch base 8 and the switch cover 6, so that the switch can be used in a harsh environment of rain and the contact is stable. The sealing ring 5 is extruded and deformed and arranged between the switch base 8 and the switch cover 6, and fills the gap between the switch base 8 and the switch cover 6 to ensure a stable seal between the switch base 8 and the switch cover 6. Because the sealing parts are squeezed when installed, rainwater will not enter, so that the function of the entire product can be realized and work normally.

[0030] 2. A sealing sleeve 2 is added to the design of this application. The sealing sleeve 2 is squeezed and connected to the switch contact 1, and moves back and forth with the contact 1 to ensure the sealing effect between the sealing sleeve 2 and the contact 1. The bottom of the sealing sleeve 2 and the base and upper cover of the switch produce a sealing effect through squeezing, ensuring that rainwater cannot enter the inside of the switch, thereby achieving the technical effect of protecting the switch from rain.

[0031] 3. The design of this application adds a sealant 7, which is an adaptive structure generated by filling the sealant 7 in the glue groove at the upper end of the terminal 4 and the switch cover 6, thereby ensuring that there will be no water leakage at the upper end of the terminal 4 and the switch cover 6, thereby improving the waterproof function and reliability of the product.

Specific examples are used herein to illustrate the principles and implementation methods of the technical solution of the present utility model. The above examples are only used to help understand the method of the present utility model and its core idea. The above is only a preferred embodiment of the present utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should all be regarded as the scope of protection of the present utility model.
