Description

Technical Field

[0001] This utility model belongs to the field of basic electrical component technology, and in particular relates to a socket protective cover. Background Technology

[0002] A socket cover is an insulating component inserted into a socket socket to reduce the possibility of accidental electric shock to children and pets. Chinese patent documents disclose various socket covers, such as a socket cover (application number 201120194841.2), an interlocking socket cover (application number 201120408447.4), and a socket cover (application number 201520845205.X); they typically include insulated prongs and a cover plate.

[0003] Chinese patent documents also disclose a power socket protective cover, application number 201620451516.2, which includes a pull tab and a movable switch. Theoretically, by sliding the movable switch, the movable switch can prevent the pull tab from rotating, reducing the possibility of children pulling out the socket protective cover. However, the movable switch has the problem of being able to slide freely and children can easily assume that the movable switch is moving, and then rotate the pull tab and pull out the socket protective cover. Summary of the Invention

[0004] This utility model proposes a socket protective cover. The technical problem to be solved by this utility model is how to propose a socket protective cover that can further reduce the possibility of children turning the pull tab.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution: A socket protective cover includes a cover plate, an insulating pin, a pull tab, and a movable switch. One end of the insulating pin is fixedly connected to the cover plate. The edge of the cover plate has a groove that matches the pull tab. The pull tab and the cover plate are rotatably connected by a shaft, and the pull tab can rotate into the groove. The movable switch and the cover plate are connected by a linear sliding connection structure. When the movable switch is embedded in the groove, the movable switch can block the rotation of the pull tab located in the groove. The feature is that when the movable switch is embedded in the groove, the movable switch and the cover plate are also connected by a positioning structure. The cover plate is made of plastic and has a U-shaped groove. The inner area of ​​the U-shaped groove in the cover plate is an elastic strip. The positioning structure includes a first positioning part and a second positioning part that cooperate with each other. The first positioning part is disposed on the movable switch, and the second positioning part is disposed on the elastic strip.

[0006] Compared with existing technologies, the elastic strip in this socket protective cover is formed by the material characteristics of the cover plate itself and the setting of U-shaped grooves, and there is no additional manufacturing cost required to manufacture the elastic strip.

[0007] By placing the second positioning part on the elastic strip, the overlap size of the first and second positioning parts can be increased. This not only increases the initial force when the active switch is pushed from the embedded state to the disengaged state, reducing the possibility of accidental sliding of the active switch and improving the stability of the active switch when it is embedded in the slot, but also reduces the possibility of children pushing the active switch and turning the pull tab. Furthermore, it improves the feel of operating the active switch, so that the fingers can clearly feel the matching of the first and second positioning parts when the active switch is pushed from the disengaged state to the embedded state.

[0008] In the aforementioned socket protective cover, there are two U-shaped grooves and two elastic strips, with the two elastic strips located on both sides of the linear sliding connection structure; there are two sets of positioning structures, with each set corresponding to one of the two elastic strips; this structure further improves positioning stability and reduces the possibility of children pushing the movable switch.

[0009] In the aforementioned socket protective cover, the positioning structure further includes a third positioning part, which is disposed on the elastic strip. When the active switch is in a completely disengaged state, the first positioning part and the third positioning part cooperate. This structure reduces the possibility of the active switch sliding freely and improves the ease of use of the socket protective cover.

[0010] In the aforementioned socket protective cover, the first positioning part is a hemispherical protrusion, and the second and third positioning parts are hemispherical grooves.

[0011] In the aforementioned socket protective cover, the linear sliding connection structure includes a linear groove on the cover plate and a connecting plug embedded in the linear groove; one end of the connecting plug is fixedly connected to the active switch, and the connecting plug has a sliding guide section that cooperates with the side wall of the linear groove to form a guide; the other end of the connecting plug is an anti-disengagement part that contacts the back of the cover plate.

[0027] like Figures 1 to 9 As shown, the socket protective cover includes a cover plate 1, insulated pins 2, a pull tab 3, and a movable switch 4.

[0028] One end of the insulating pin 2 is fixedly connected to the cover plate 1. The attached diagram in the instruction manual shows that the insulating pin 2 and the cover plate 1 are integrated, but depending on the actual situation, the insulating pin 2 and the cover plate 1 can also be plugged in. The attached diagram in the instruction manual shows that there are 3 insulating pins 2, but depending on the actual situation, there can also be 1 or 2 insulating pins 2.

[0029] The buckle 3 is approximately "C" shaped. The edge of the cover plate 1 has a groove 1a that matches the buckle 3. A shaft hole 1b is provided on the side wall of the groove 1a. The buckle 3 has a shaft portion 3a that is embedded in the shaft hole 1b. Thus, the buckle 3 and the cover plate 1 are rotatably connected by the shaft, and the buckle 3 can rotate into the groove 1a.

[0030] The movable switch 4 is connected to the cover plate 1 via a linear sliding connection structure. When the movable switch 4 is embedded in the groove 1a, it can prevent the pull tab 3 located in the groove 1a from rotating. The linear sliding connection structure includes a linear groove 1c on the cover plate 1 and a connecting plug 5 embedded in the linear groove 1c. One end of the connecting plug 5 is fixedly connected to the movable switch 4. The attached drawings show that the connecting plug 5 and the movable switch 4 are integrated. The connecting plug 5 has a sliding guide section 5a that cooperates with the side wall of the linear groove 1c to form a guide. The other end of the connecting plug 5 is an anti-disengagement hook part 5b that contacts the back of the cover plate 1. When assembling the movable switch 4 and the cover plate 1, the anti-disengagement hook part 5b is broken by pressing the movable switch 4 into the linear groove 1c. This has the advantages of simple structure, convenient assembly, low manufacturing cost, and stable sliding of the movable switch 4.

[0031] The cover plate 1 is made of plastic and has a U-shaped groove 1d. The inner area of ​​the U-shaped groove 1d in the cover plate 1 is an elastic strip 1e. The accompanying drawings show that there are two U-shaped grooves 1d and two elastic strips 1e, which are located on both sides of the straight groove 1c.

[0032] The movable switch 4 and the cover plate 1 are also connected by two sets of positioning structures; the two sets of positioning structures are arranged one-to-one with the two elastic strips 1e. The positioning structure includes a first positioning part 4a, a second positioning part 1f, and a third positioning part 1g that cooperate with each other. The first positioning part 4a is disposed on the movable switch 4, and the second positioning part 1f and the third positioning part 1g are disposed on the elastic strips 1e. Figure 7 As shown, when the active switch 4 is in the embedded slot 1a state, the first positioning part 4a and the second positioning part 1f cooperate; as Figure 9 As shown, when the active switch 4 is fully disengaged from the slot 1a, the first positioning part 4a and the third positioning part 1g engage. The accompanying drawings show the first positioning part 4a as a hemispherical protrusion, and the second positioning part 1f and the third positioning part 1g as hemispherical grooves.
