Description

Technical Field

[0001] The utility model relates to a socket. Background Art

[0002] As the types of electrical appliances increase day by day, and each electrical appliance has a plug to conduct power, the number of sockets cannot meet the use requirements, and power extension cords are needed to increase the number of sockets. The most common power extension cord currently has more than three sets of AC sockets on a long socket, and one end of the socket is provided with a cable and a plug to be plugged into an external power source, so that the number of sockets can be expanded to accommodate more different electrical products.

[0003] For example, the "Multi-function Adapter Socket" disclosed in the Chinese utility model patent with patent number CN201520900390.8 (publication number CN205081336U) includes a socket body and a plug connected to the socket body. The socket body includes an upper cover and a lower cover fixed together, a grounding plate and a pair of conductive plates located between the upper cover and the lower cover, a shielding plate assembled on the upper cover, a switch and a fuse box.

[0004] The patent mentions that the conductive sheet is connected to the switch, but the patent does not disclose how the conductive sheet and the switch are connected. If the connection between the conductive sheet and the switch is not firm, it is easy for the switch to be unable to effectively control the on and off of the current. Therefore, the connection between the switch and the conductive sheet needs to be studied. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a socket with good connection stability between a conductive sheet and a switch in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a socket, including a strip-shaped shell, a conductive sheet and a switch are provided in the shell, the conductive sheet extends along the length direction of the shell, the switch is located at the end of the conductive sheet, and is characterized in that the end of the conductive sheet is bent to form a U-shaped positioning portion, the switch is provided with a power connection sheet, and the power connection sheet is embedded in the U-shaped groove of the positioning portion.

[0007] In order to prevent the positioning part from being separated from the power connection plate, a limiting rib is provided on the switch beside the power connection plate, and the notch of the U-shaped groove is facing the limiting rib, which can prevent the positioning part from being displaced in the direction where the limiting rib is located.

[0008] In order to position the conductive sheet, at least two vertically extending positioning rods are spaced apart in the shell along its length direction, and the positioning rods are provided with embedding grooves with open tops. The corresponding parts of the conductive sheet are embedded in the embedding grooves to position the conductive sheet in the horizontal direction, otherwise the conductive sheet will be displaced, which will also cause displacement between the positioning part and the power connection sheet.

[0009] In order to facilitate embedding the conductive sheet in the embedding groove, the top of the embedding groove is a trumpet-shaped structure with a larger top and a smaller bottom.

[0010] In order to further position the conductive sheet, the conductive sheet is provided with a vertically penetrating positioning groove, and the positioning grooves are provided in plurality and arranged in sequence along the length direction of the conductive sheet, and the housing is provided with a plurality of positioning posts inserted into the positioning grooves along the length direction thereof. The cooperation between the positioning posts and the positioning grooves further realizes the positioning of the conductive sheet.

[0011] In the above scheme, there are two conductive sheets, namely the live wire conductive sheet and the neutral wire conductive sheet. The shell is also provided with a grounding connecting sheet extending along its length direction. The grounding connecting sheet is located below the conductive sheet. The grounding connecting sheet is provided with a plurality of pins in sequence along its length direction, and the ends of the pins pass through the bottom wall of the shell.

[0012] In order to save materials, the interior of the pin is hollow.

[0013] In the above scheme, the shell is provided with a through hole for the power cord to pass through, one end of the power cord is connected to the plug, and the other end is simultaneously connected to the live wire conductive sheet, the neutral wire conductive sheet and the grounding connecting sheet.

[0014] In order to save costs, a wire clamp is provided in the housing at a portion adjacent to the perforation, the wire clamp is located between the switch and the perforation, and the end of the grounding connecting piece is provided adjacent to the wire clamp. Because the cost of the power cord is higher than that of the grounding connecting piece, the present application is designed in such a way that the length of the power cord is shorter and the length of the grounding connecting piece is longer, so as to achieve the purpose of saving costs.

[0015] In order to facilitate the placement of components such as conductive sheets and switches in the housing, the housing includes an upper shell and a lower shell connected to form an installation cavity, in which the conductive sheets, switches and grounding connecting sheets are all arranged.

[0016] Compared with the prior art, the utility model has the following advantages: the utility model bends the end of the conductive sheet to form a U-shaped positioning portion, and provides a power connection sheet on the switch that can be embedded in the U-shaped groove of the positioning portion. In this way, the connection between the conductive sheet and the switch is relatively stable and not easy to separate, thereby improving the reliability of the switch operation.

[0024] like Figures 1 to 6 As shown, the socket of this preferred embodiment includes a housing 1, a conductive sheet 2, a switch 3, a grounding connecting sheet 4, a pin 5, etc.

[0025] The housing 1 is strip-shaped and includes an upper housing 11 and a lower housing 12 connected to each other. The upper housing 11 and the lower housing 12 are connected by screws to form a mounting cavity. The conductive sheet 2, the switch 3, and the grounding connecting sheet 4 are all arranged in the mounting cavity.

[0026] like Figure 6 As shown, the conductive sheet 2 extends along the length direction of the housing 1, the switch 3 is located at the end of the conductive sheet 2, the end of the conductive sheet 2 is bent to form a U-shaped positioning portion 21, and the switch 3 is provided with a power connection sheet 31, which is embedded in the U-shaped groove 211 of the positioning portion 21.

[0027] In addition, a limiting rib 32 is provided on the switch 3 beside the power connection plate 31 , and the notch of the U-shaped groove 211 is facing the limiting rib 32 , which can prevent the positioning part 21 from moving in the direction of the limiting rib 32 , thereby preventing the positioning part 21 from being separated from the power connection plate 31 .

[0028] At least two vertically extending positioning rods 13 are provided in the housing 1 along its length direction at intervals. The positioning rods 13 are provided with an embedding groove 131 with an open top. The corresponding part of the conductive sheet 2 is embedded in the embedding groove 131 to position the conductive sheet 2 in the horizontal direction. Otherwise, the conductive sheet 2 will be displaced, which will also cause displacement between the positioning portion 21 and the electrical connection sheet 31. In this embodiment, the top of the embedding groove 131 is a trumpet structure 132 with a larger top and a smaller bottom, which facilitates embedding the conductive sheet 2 in the embedding groove 131.

[0029] In addition, the conductive sheet 2 has a vertically penetrating positioning groove 22, and there are multiple positioning grooves 22 arranged in sequence along the length direction of the conductive sheet 2. The housing 1 is provided with multiple positioning posts 14 inserted into the positioning grooves 22 along its length direction. The cooperation between the positioning posts 14 and the positioning grooves 22 further realizes the positioning of the conductive sheet 2.

[0030] In this embodiment, there are two conductive sheets 2, namely a live wire conductive sheet and a neutral wire conductive sheet. The shell 1 is also provided with a grounding connecting sheet 4 extending along its length direction. The grounding connecting sheet 4 is located below the conductive sheet 2. A plurality of pins 5 are sequentially provided on the grounding connecting sheet 4 along its length direction. The ends of the pins 5 pass through the bottom wall of the shell 1.

One end of the power cord 7 is connected to the plug 71, and the other end is simultaneously connected to the live wire conductive sheet, the neutral wire conductive sheet, and the grounding connecting sheet 4. In this embodiment, both the upper housing 11 and the lower housing 12 are provided with an arc hole 15. After the upper housing 11 and the lower housing 12 are connected, the two arc holes 15 are aligned to form the through hole.

Because the cost of the power cord 7 is higher than that of the grounding connecting piece 4, the present application is designed in such a way that the length of the power cord 7 is shorter and the length of the grounding connecting piece 4 is longer, so as to achieve the purpose of cost saving.

[0033] In addition, a protection door 8 is provided between the ground connection sheet 4 and the conductive sheet 2 . The protection door 8 is a prior art and will not be described in detail herein.
