Description

Technical Field

[0001] This utility model belongs to the field of power sockets, specifically relating to a waterproof and safe socket insulating shell. Background Technology

[0002] The socket casing, as a crucial component of the socket, plays a vital role, affecting not only its aesthetics and durability but also serving as a solid line of defense for safe electricity use. It is typically made of high-quality engineering plastics or metals, materials with excellent insulation and flame-retardant properties, effectively preventing the risk of fire caused by current leakage and short circuits. Modern socket casings generally employ a sealed structure, utilizing rubber sealing rings or waterproof strips to form an effective waterproof barrier between the socket and the wall, effectively preventing moisture from seeping into the socket through gaps and avoiding the risk of short circuits and electric shocks caused by water splashes or damp environments.

[0003] However, power strip sockets are essentially extension cord sockets, and cannot achieve waterproofing through a sealed barrier with the wall. Therefore, the waterproofing of existing power strip sockets is generally limited. Furthermore, in traditional power strip sockets, the live and neutral wires are located in the same cavity. When the power strip is in a humid environment, water may accumulate inside the socket casing. Since water is conductive, the live and neutral wires can easily become connected, potentially causing electrical leakage. Therefore, to improve electrical safety, prevent damage to the internal live and neutral wires due to water immersion, and extend the lifespan of the power strip, it is necessary to address the water accumulation problem. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by providing a waterproof safety socket insulating shell.

[0005] To achieve the above objectives, the utility model adopts the following technical measures:

[0006] An insulating shell for a waterproof safety socket includes an insulating upper cover and an insulating lower cover. The insulating lower cover has an internal partition wall that divides the inner cavity of the insulating lower cover into an independent live wire mounting cavity and a neutral wire mounting cavity. Both the live wire mounting cavity and the neutral wire mounting cavity are provided with terminal mounting support frames. The bottom of the insulating lower cover is provided with a drainage hole.

[0007] Preferably, the isolation wall adopts a Y-shaped structure, with the ground wire mounting cavity located at one end of the isolation wall between the live wire mounting cavity and the neutral wire mounting cavity.

[0008] Preferably, the two opposite side walls inside the grounding mounting cavity are provided with limiting grooves, and a first support block and a second support block are provided between the two limiting grooves. The first support block and the second support block are both provided with positioning posts.

[0009] Preferably, the tops of the first and second support blocks are flush with the bottom of the limiting groove, and the tops of the two positioning columns are flush with the top of the isolation wall.

[0010] Preferably, the terminal mounting support includes a first support block, a second support block, and a third support block, wherein the height of the first support block is lower than the height of the second support block, and the height of the second support block is lower than the height of the third support block.

[0011] Preferably, the top of the third support block is an inclined surface, and a slot is provided on the inclined surface.

[0012] Preferably, at least two vertically arranged limiting strips are provided on the inner wall of one side of the live wire mounting cavity and the neutral wire mounting cavity.

[0013] Preferably, the insulating upper cover has at least two outer side walls with snap-fit ​​grooves, and snap-fit ​​blocks are provided in the snap-fit ​​grooves. The insulating lower cover has plug-in blocks on both sides that mate with the snap-fit ​​grooves, and the plug-in blocks have snap-fit ​​grooves on their inner sides that mate with the snap-fit ​​blocks.

[0014] Preferably, the bottom of the insulating cover is provided with a limiting mounting post and a terminal limiting pressure block, and one side of the terminal limiting pressure block is provided with a limiting block with an inclined bottom surface.

[0015] Preferably, the insulating lower cover has a stationary terminal fixing slot on one side, and the bottom of the stationary terminal fixing slot is higher than the top of the third support block.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model discloses a waterproof safety socket insulating shell. The insulating shell has a simple structure, is easy to manufacture, and helps reduce production costs. The insulating shell divides the inner cavity of the lower insulating cover into independent live wire and neutral wire mounting cavities via an isolation wall. Even if water enters the socket, it will enter the separate live wire and neutral wire mounting cavities, meaning the live and neutral wires will not be connected by water. Water enters the socket independently, preventing the formation of a circuit that could cause leakage or short circuits. Furthermore, each of the live and neutral wire mounting cavities is equipped with a terminal mounting support frame, which suspends the live and neutral wires, allowing water to flow downwards to the bottom of the lower insulating cover, preventing the live and neutral wires from being submerged in water. The bottom of the lower insulating cover has a drainage hole, allowing water to drain out, thereby reducing water erosion of the live and neutral wires and extending the socket's service life.

Each of the live wire mounting cavity 22 and the neutral wire mounting cavity 23 is provided with a terminal mounting support frame 25, and the live wire and the neutral wire are respectively mounted on the terminal mounting support frame 25 in the live wire mounting cavity 22 and the neutral wire mounting cavity 23, so that the live wire and the neutral wire do not contact the bottom of the insulating lower cover 2. The bottom of the insulating lower cover 2 is provided with a drainage hole 24, and there are multiple drainage holes 24, which are respectively located at the bottom of the live wire mounting cavity 22 and the neutral wire mounting cavity 23.

[0026] The isolation wall 21 adopts a Y-shaped structure. The ground wire mounting cavity 26 is located at one end of the isolation wall 21 between the live wire mounting cavity 22 and the neutral wire mounting cavity 23. The ground wire mounting cavity 26 is triangularly distributed with the live wire mounting cavity 22 and the neutral wire mounting cavity 23. The ground wire mounting cavity 26 can be used to install the ground wire. The ground wire mounting cavity 26 can adopt a U-shaped groove structure, a square groove structure, a corner groove structure, or other regular groove structure. The isolation wall 21 is preferably integrally formed with the insulating lower cover 2. In other embodiments, the isolation wall 21 can also be designed separately from the insulating lower cover 2, and then installed in the inner cavity of the insulating lower cover 2 by means of bonding, welding, snap-fitting, or connecting parts.

[0027] In detail, the ground wire mounting cavity 26 has limiting grooves 261 on both opposite side walls. The ground wire is installed on the limiting grooves 261. Specifically, the two ends of the ground wire are snapped into or placed directly on the two limiting grooves 261. The limiting grooves 261 have an L-shaped or C-shaped cross-section. In this embodiment, a first support block 262 and a second support block 263 are located within the ground wire mounting cavity 26. The first support block 262 and the second support block 263 are positioned between the two limiting grooves 261. The tops of the first support block 262 and the second support block 263 are flush with the bottom of the limiting grooves 261. The first support block 262 and the second support block 263 are used to support the ground wire. In addition, the first support block 262 and the second support block 263 are each provided with a positioning post 264.

The insertion holes on the insulating upper cover 1 are respectively aligned with the live wire mounting cavity 22, the neutral wire mounting cavity 23, and the ground wire mounting cavity 26.
