Description

Technical Field

[0001] This utility model belongs to the field of rocker switch technology, specifically a rocker switch dust cover. Background Technology

[0002] Rocker switches, as a common electrical control component, are widely used in various electronic products, home appliances, and industrial control equipment due to their ease of operation and simple appearance. In the field of electronic products, such as televisions, computer mainframes, and audio equipment, rocker switches are used to turn the power on and off. In home appliances, such as microwave ovens, rice cookers, and electric water heaters, they control the operating status of the appliances. In industrial control equipment, rocker switches are also often used for starting, stopping, and switching modes, and are one of the key components to ensure the normal operation of the equipment. Despite their wide application, dust intrusion seriously affects their performance and service life during actual use.

[0003] A dustproof rocker switch with publication number CN222619625U relates to the field of electronic component technology. It includes a housing and a dust cover. The top of the housing has a slot, and a switch button is provided inside the slot. A female locking block is fixedly connected to one side of the outer surface of the housing near the center. The top of the female locking block has a locking groove near the center. A female locking block is fixedly connected to one side of the outer surface of the dust cover near the center. A locking rod is fixedly connected to the bottom of the female locking block near the center, and the locking rod is engaged with the locking groove. The bottom of the dust cover has a groove. In typical indoor environments, although relatively clean, a significant amount of dust particles still exist. This dust can enter the rocker switch through its operating gaps and pin interfaces. Over time, dust accumulates inside the switch, increasing the contact resistance between the contacts. This can lead to poor contact, causing the device to fail to start or operate unstably. For example, in a household television, if dust intrusion causes poor contact in the rocker switch, it may result in frequent power-on failures or automatic shutdowns, causing considerable inconvenience to the user.

[0004] Therefore, a dust cover for a rocker switch is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a dust cover for a rocker switch, which has the advantages of preventing dust from entering the interior of the rocker switch, reducing dust intrusion, and extending its service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rocker switch dust cover, including a protective sleeve, a cable is provided inside the protective sleeve, and a plug terminal is welded to one end of the cable. A terminal shell is snapped onto the outside of the plug terminal. A connecting protective sleeve is welded to the other end of the protective sleeve through an internal cable. A dustproof component is provided inside the connecting protective sleeve. The dustproof assembly includes a plug main housing that fits into the connecting protective sleeve. A plug body is integrally provided on the rear side of the plug main housing. A docking seat integrally provided with the plug body is fixed inside the plug main housing.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following describes an embodiment of this utility model based on its overall structure.

[0019] like Figures 1 to 6 As shown, this utility model provides a dust cover for a rocker switch, including a protective sleeve 1. The protective sleeve 1 has a cable inside, and a plug terminal 3 is welded to one end of the cable. A terminal housing 2 is snapped onto the outside of the plug terminal 3. The other end of the protective sleeve 1 is welded to a connecting protective sleeve 5 through an internal cable. A dustproof component 7 is provided inside the connecting protective sleeve 5. The dustproof component 7 includes a plug main housing 71 that fits into the connecting protective sleeve 5. The rear side of the plug main housing 71 is integrally provided with a plug body 72. The inside of the plug main housing 71 is fixedly provided with a docking seat 74 that is integrally provided with the plug body 72. The outside of the docking seat 74 is covered with a silicone dustproof cover 75.

[0020] In this embodiment, a cable clip 4 is slidably provided on the outer side of the protective sleeve 1. The inside of the cable clip 4 is flared, and the flared shape is installed facing the plug 73, positioning the cable clip 4 on the outer side of the protective sleeve 1 to form a whole.

[0021] A male connector 6 is fixedly installed on the outside of the protective sleeve 5. The cables of the protective sleeve 1 are black, white and red. The male connector 6 has a connecting electrode plate that connects to the white wire and the black wire to the red wire to ensure electrical safety.

[0022] A panel 79 is rotatably provided inside the front side of the plug main housing 71, and the panel 79 is flush with the surface of the plug main housing 71. The panel 79 is limited to rotating inside the plug main housing 71.

[0023] The surface of the silicone dust cover 75 has an insertion hole 76. A limiting post 77 that is fixed to the docking seat 74 is inserted into the insertion hole 76. The silicone dust cover 75 is positioned on the outside of the limiting post 77 to strengthen the positioning and prevent tilting.

[0024] The surface of the limiting post 77 is provided with a positioning hole, and the inside of the limiting post 77 is magnetically attached to a magnetic positioning head 78 that fits with the silicone dust cover 75. The magnetic positioning head 78 can magnetically position the inside of the positioning hole of the limiting post 77 and position the silicone dust cover 75 on the outside.

[0025] The panel 79 has an integrally provided terminal block 710 inside, and the terminal block 710 is inserted into the inside of the docking seat 74 and is soldered to the plug 73 through the cable. The extended cable and the plug 73 are soldered into a circuit through the terminal block 710.

[0026] The working principle and process of a rocker switch dust cover: When the rocker switch is not in use, the silicone dust cover 75 tightly fits the inner side of the mating seat 74, covering the connection surface of the mating seat 74. The limiting post 77 is inserted into the insertion hole 76 on the surface of the silicone dust cover 75, and through the positioning hole and the magnetic attraction of the magnetic positioning head 78, the silicone dust cover 75 is firmly fixed to the outside of the mating seat 74, preventing it from shifting due to vibration or external force. At this time, the panel 79 is flush with the surface of the plug main housing 71, forming an integral sealing structure, preventing dust from passing through the gaps of the mating seat 74. Upon entering, basic dust protection is achieved. When the rocker switch needs to be operated, rotate the front panel 79 of the plug's main housing 71 to expose the internal wiring terminals 710 and the docking seat 74. After the silicone dust cover 75 is exposed along with the docking seat 74, if external equipment is required, it can be aligned with the external plug through the socket 76 (the limiting post 77 acts as a guide and positioner). When the external plug is inserted, it compresses the silicone dust cover 75, causing elastic deformation, which ensures a tight connection and reduces gaps through the resilience of the silicone. After the connection is complete, the magnetic attraction is activated. The metal parts of the connector 78 and the external plug are attracted to each other, enhancing connection stability. Meanwhile, the silicone dust cover 75 still covers the edges of the mating area, reducing the risk of dust entering during operation. The cable clip 4 on the outside of the protective sleeve 1 is flared towards the plug 73. The gap between the protective sleeve 1 and the cable can be tightened by sliding adjustment to prevent dust from entering from the cable inlet. The male connector 6 on the outside of the protective sleeve 5 achieves circuit continuity of the cables (black, white, and red) through internal electrode plates. Simultaneously, the fitting structure between the protective sleeve 5 and the plug main housing 71 further strengthens the overall seal, preventing dust from seeping through the component connection. After operation, the external plug is unplugged, and the silicone dust cover 75 resets under its own elasticity, realigning the socket 76 with the limiting post 77. The panel 79 is rotated in the opposite direction to make it flush with the surface of the plug main housing 71, and the magnetic positioning head 78 again attracts the limiting post 77. The silicone dust cover 75 returns to full coverage of the mating seat 74, returning to a sealed and dustproof state, ensuring the interior remains clean before the next use. This utility model achieves dust isolation at the rocker switch docking point through the fitting structure of the dustproof component 7 and the connecting protective sleeve 5, combined with the sealing protection of the silicone dustproof cover 75; at the same time, it uses mechanical structures such as magnetic positioning and limit post 77 insertion to ensure that the dustproof component 7 can be stably sealed in both use and idle states, which does not affect the normal operation of the switch and can effectively prevent dust from entering.
