Description

Technical Field

[0001] This utility model relates to the field of power switch technology, specifically to a switch housing and a touch switch. Background Technology

[0002] During the use of electrical switches, they are often corroded by external liquids. When external liquids enter the switch housing, they can damage the components inside the switch housing, causing the entire switch to malfunction. However, when the switch housing is made enclosed, the disadvantages are that it is impossible to inspect and repair the inside of the switch, and it is also impossible to replace vulnerable parts, which brings a lot of inconvenience to engineers and users. Summary of the Invention

[0003] The purpose of this invention is to provide a switch housing and a touch switch to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The first aspect of this utility model provides a switch housing, which includes a first housing and a second housing. The first housing has a first connecting surface in the circumferential direction, and the second housing has a second connecting surface in the circumferential direction. The first connecting surface and the second connecting surface are mated and connected, and a receiving cavity is formed between the first housing and the second housing.

[0006] The first housing and / or the second housing are provided with a receiving groove, which is located at the mating connection and is used to accommodate the sealing strip at the mating connection.

[0007] The switch housing of this utility model is a split type. The first housing and the second housing are connected to form a receiving cavity. Multiple components or circuit boards can be placed in the receiving cavity. When it is necessary to inspect the components or circuit boards inside the receiving cavity, the switch housing can be opened for subsequent maintenance.

[0008] When the switch housing is in operation, the mating connection between the first housing and the second housing reduces the intrusion of external fluids by the cooperation of the first connecting surface and the second connecting surface. In addition, a receiving groove is provided at the mating connection to accommodate the sealing strip, and the sealing strip seals and waterproofs the mating connection.

[0009] In one embodiment of the switch housing of this utility model, the receiving groove is disposed on the outside of the receiving cavity.

[0010] By placing the receiving groove for accommodating the sealing strip outside the receiving cavity, external fluids can be prevented from entering the receiving cavity, making it easier to protect the components inside the receiving cavity.

[0011] In one embodiment of the switch housing of this utility model, a portion of the sidewall of the first housing and / or the second housing extends outward to form the receiving groove.

[0012] The receiving groove can be disposed on the first housing or on the second housing. The receiving groove is formed by extending outward from a portion of the sidewall of the first or second housing, thereby increasing the strength of the entire switch housing.

[0013] In one embodiment of the switch housing of this utility model, the first housing and the second housing are detachably connected.

[0014] The first and second housings are detachably connected, allowing them to be separated when needed to check whether the components inside the cavity are working properly, and to replace the components if they are not working properly.

[0015] In one embodiment of the switch housing of this utility model, the receiving groove includes a bent component;

[0016] One end of the bent component is connected to the side wall of the first housing and / or the second housing, and forms a recess with the side wall, the recess facing the mating connection; and / or, the bent component and the first housing are integral structures, and the bent component and the second housing are integral structures.

[0017] The recess formed between the bent member and the first or second housing is used to accommodate the sealing strip at the sealing connection, preventing external liquid from entering the receiving cavity through the sealing connection and thus damaging the components inside the receiving cavity.

[0018] By integrating the bent component with the first housing, the strength of the first housing can be improved. The bent component acts as a reinforcing rib on the side wall of the first housing. Similarly, by integrating the bent component with the second housing, the strength of the second housing can be improved. The bent component also acts as a reinforcing rib on the side wall of the second housing.

[0019] In one embodiment of the switch housing of this utility model, the switch housing further includes a sealing strip, which is disposed in the receiving groove and can seal the mating connection.

[0020] By setting a sealing strip and placing the sealing strip inside the receiving groove, fluid from the external environment is prevented from entering the sealed connection and the interior of the receiving cavity.

[0021] In one embodiment of the switch housing of this utility model, part of the sealing strip is disposed between the first connecting surface and the second connecting surface to seal the mating connection.

[0022] Some seals can reduce the sealing defects caused by machining errors between the first and second connecting surfaces. The seals, together with the first and second connecting surfaces, form a sealing structure, thereby isolating the interior of the cavity from the external environment.

[0023] In one embodiment of the switch housing of this utility model, the first housing is provided with two first connecting surfaces, which are stepped, and the second housing is provided with two second connecting surfaces, which are also stepped.

[0024] The stepped sealing structure allows for better assembly of the first and second housings, while also making the connection between the first and second connecting surfaces more secure.

[0025] A second aspect of this utility model provides a touch switch, the touch switch comprising a switch housing as described in any of the preceding claims;

[0026] The first housing and / or the second housing are provided with at least one touch opening, which is connected to the receiving cavity.

[0027] The touch area at the touch opening can close or disconnect the circuit when the user touches the area.

[0028] In one embodiment of the touch switch of this utility model, the touch switch further includes an external connector, and the external connector is provided with a snap-fit ​​structure between itself and the first housing or the second housing. The receiving groove and the mating connection are located on one side of the external connector.

[0029] The external connector securely connects the switch housing to other external components. With the external connector in the way, the receiving groove and sealing connection are hidden on one side, so that the user cannot see the receiving groove and sealing connection from the other side of the external connector, thus achieving an aesthetic and decorative effect.
