Description

Technical Field

[0001] This utility model relates to a socket. Background Technology

[0002] With the increasing variety of electrical appliances, and each appliance having a plug to conduct power, the number of sockets is often insufficient to meet usage demands, necessitating the use of power extension cords to increase the number of sockets. The most common type of power extension cord is a long, narrow socket with three or more AC outlets. One end of the socket has a cable and plug for connecting to an external power source, thus expanding the number of sockets to accommodate a wider range of different electrical appliances.

[0003] For example, the Chinese utility model patent disclosed in patent application number CN201520900390.8 (publication number CN205081336U) is a "multifunctional adapter socket", which 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 a conductive sheet is connected to a switch, but the connection between the conductive sheet and the switch is not disclosed. If the connection between the conductive sheet and the switch is not secure, the switch may not be able to effectively control the flow of current. Therefore, the connection between the switch and the conductive sheet needs further research. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a socket with good stability in the connection between the conductive sheet and the switch, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a socket, including a strip-shaped housing, wherein a conductive sheet and a switch are provided in the housing, the conductive sheet extends along the length direction of the housing, characterized in that the switch is provided with a contact piece located at the end of the conductive sheet, the end of the conductive sheet is provided with a first connecting piece and a second connecting piece extending along the width direction of the housing, the first connecting piece and the second connecting piece are arranged sequentially in the vertical direction, and the first connecting piece and the second connecting piece are spaced apart along the length direction of the housing, the contact piece is sandwiched between the first connecting piece and the second connecting piece, the two walls of the contact piece arranged opposite to each other along the length direction of the housing are the first wall and the second wall, the first wall and the first connecting piece are welded together, and / or, the second wall and the second connecting piece are welded together.

[0007] Preferably, the first wall surface and the first connecting piece are connected by spot welding, and the contact area between the first connecting piece and the first wall surface of the electrical contact piece is greater than the contact area between the second connecting piece and the second wall surface of the electrical contact piece.

[0008] To facilitate welding of the first connecting piece, the first connecting piece is positioned above the second connecting piece.

[0009] To facilitate the formation of the conductive sheet, the first connecting sheet, and the second connecting sheet, a strip extends along the length of the shell. This strip has a groove extending along its length and extending through one end. The portion above the groove is bent to form the first connecting sheet, and the portion below the groove is bent to form the second connecting sheet. The portion beside the groove is the conductive sheet. This method simply requires creating a groove on the strip and then bending it at the groove to form the first and second connecting sheets, resulting in a simple structure that is easy to manufacture.

[0010] In order to make the area of ​​the first connecting piece larger than that of the second connecting piece, the vertical height of the part above the strip groove is greater than that of the part below the strip groove. Because the area of ​​the first connecting piece is larger, a groove is provided at the top of the part above the strip groove to facilitate bending of the first connecting piece. The first connecting piece is formed by bending near the groove.

[0011] During welding, there will be overflow material. Therefore, in the above solution, the contact piece is provided with overflow holes that run through the front and back to accommodate the overflow material.

[0012] To prevent the contact plate and the conductive plate from shifting in the width direction of the housing, the two walls of the contact plate that are arranged opposite to each other in the width direction of the housing are the third wall and the fourth wall. The side of the first connecting plate away from the conductive plate is bent toward the second connecting plate to form a limiting part. When the contact plate is clamped between the first connecting plate and the second connecting plate, the limiting part abuts against the third wall of the contact plate.

[0013] The switch is also provided with a limiting rib, which is located on the side of the limiting part away from the conductive sheet. The limiting rib can abut against the limiting part. The limiting rib and the limiting part work together to fix the electrical contact and the conductive sheet relatively in the width direction of the housing. The first connecting piece and the second connecting piece work together to fix the electrical contact and the conductive sheet relatively in the length direction of the housing. This not only achieves relative fixation between the electrical contact and the conductive sheet, but also facilitates subsequent welding.

[0014] In the above scheme, there are two conductive sheets arranged sequentially along the width direction of the shell, namely a live wire conductive sheet and a neutral wire conductive sheet. The switch is provided with a contact piece corresponding to each conductive sheet. There is one limiting rib, and the limiting parts on both conductive sheets abut against the limiting rib.

[0015] In the above solution, the housing is further provided with a grounding connection piece extending along its length direction. Multiple grounding clips are spaced apart on the grounding connection piece along its length direction. Each grounding clip is U-shaped and includes a connecting arm connected to the grounding connection piece by a connector and support arms formed at both ends of the connecting arm. The support arms protrude out of the housing for contact with the plug of the electrical appliance.

[0016] The connector includes a connecting post and positioning parts formed at both ends of the connecting post. The connecting post passes through the grounding connecting piece and the connecting arm, and the two positioning parts press against the connecting arm and the grounding connecting piece respectively.

[0017] Compared with the prior art, the advantages of this utility model are as follows: By setting a first connecting piece and a second connecting piece at the end of the conductive sheet, and the first connecting piece and the second connecting piece are spaced apart along the length direction of the shell, a region for clamping the contact piece is formed between the first connecting piece and the second connecting piece, and the first connecting piece and / or the second connecting piece are welded to the contact piece, so that the connection stability between the contact piece and the conductive sheet is good.

[0018] In addition, the first connecting piece and the second connecting piece are arranged at intervals in the vertical direction, which facilitates the welding of the first connecting piece and / or the second connecting piece to the electrical contact piece. Otherwise, if the first connecting piece and the second connecting piece overlap in the vertical direction, they will block each other, making it inconvenient for the welding gun to weld.

[0027] In the description of this utility model patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0028] like Figures 1-6 As shown, the socket in this preferred embodiment includes a strip-shaped housing 1, in which a conductive sheet 2, a grounding connection sheet 3, and a switch 4 are provided. The switch 4 adopts an existing structure.

[0029] The conductive sheet 2 extends along the length of the housing 1. The switch 4 is provided with a receiving sheet 41 located at the end of the conductive sheet 2. In this embodiment, the outer peripheral wall of the receiving sheet 41 is formed by connecting the first wall, the third wall, the second wall and the fourth wall in sequence. The two walls of the receiving sheet 41 that are arranged opposite to each other along the length of the housing 1 are the first wall and the second wall, respectively. The two walls of the receiving sheet 41 that are arranged opposite to each other along the width of the housing 1 are the third wall and the fourth wall, respectively.

[0030] To prevent the contact plate 41 and the conductive plate 2 from shifting along the length of the housing 1, the end of the conductive plate 2 is provided with a first connecting piece 21 and a second connecting piece 22 extending along the width of the housing 1. The first connecting piece 21 and the second connecting piece 22 are arranged sequentially in the vertical direction and are spaced apart along the length of the housing 1. The contact plate 41 is clamped between the first connecting piece 21 and the second connecting piece 22.

[0031] To prevent the contact piece 41 and the conductive piece 2 from shifting in the width direction of the housing 1: the side of the first connecting piece 21 away from the conductive piece 2 is bent toward the second connecting piece 22 to form a limiting part 23. When the contact piece 41 is clamped between the first connecting piece 21 and the second connecting piece 22, the limiting part 23 abuts against the third wall surface of the contact piece 41; the switch 4 is also provided with a limiting rib 42, which is located on the side of the limiting part 23 away from the conductive piece 2, and the limiting rib 42 can abut against the limiting part 23.

[0032] The limiting rib 42 and the limiting part 23 work together to fix the connecting piece 41 and the conductive piece 2 relatively in the width direction of the housing 1. The first connecting piece 21 and the second connecting piece 22 work together to fix the connecting piece 41 and the conductive piece 2 relatively in the length direction of the housing 1. This not only achieves the relative fixation between the connecting piece 41 and the conductive piece 2, but also is equivalent to pre-positioning the connecting piece 41 and the conductive piece 2, which is convenient for subsequent welding.

[0033] To further improve the connection stability between the contact piece 41 and the conductive piece 2, the first wall surface of the contact piece 41 is welded to the first connecting piece 21, and / or the second wall surface is welded to the second connecting piece 22. Specifically, in this embodiment, the first connecting piece 21 is located above the second connecting piece 22, and the first wall surface and the first connecting piece 21 are connected by spot welding. The contact area between the first connecting piece 21 and the first wall surface of the contact piece 41 is greater than the contact area between the second connecting piece 22 and the second wall surface of the contact piece 41.

[0034] As can be seen from the above, a region for clamping the contact piece 41 is formed between the first connecting piece 21 and the second connecting piece 22, and the first connecting piece 21 and the second connecting piece 22 are arranged vertically at intervals. This facilitates the welding of the first connecting piece 21 and / or the second connecting piece 22 to the contact piece 41. Otherwise, if the first connecting piece 21 and the second connecting piece 22 overlap vertically, they will block each other, making it inconvenient for the welding gun to weld.

[0035] To facilitate the formation of conductive sheet 2, first connecting sheet 21, and second connecting sheet 22, such as Figure 4 As shown, a strip extends along the length of the housing 1. The strip has a groove 24 extending along its length and extending through one end. The portion above the groove 24 is bent to form a first connecting piece 21, and the portion below the groove 24 is bent to form a second connecting piece 22. A conductive sheet 2 is located beside the groove 24. This design simplifies manufacturing by requiring only the groove 24 to be formed and bending at the groove 24 to create the first and second connecting pieces 21 and 22.

[0036] The vertical height of the part above the strip groove 24 is greater than the vertical height of the part below the strip groove 24, which makes the area of ​​the first connecting piece 21 larger than the area of ​​the second connecting piece 22. Because the area of ​​the first connecting piece 21 is larger, a groove 25 is provided at the top of the part above the strip groove 24 to facilitate bending of the first connecting piece 21, so that the first connecting piece 21 can be formed by bending near the groove 25.

[0037] There will be overflow during welding, so the contact plate 41 is provided with overflow hole 43 that runs through the front and back to accommodate the welding overflow.

[0038] In this embodiment, there are two conductive sheets 2 arranged sequentially along the width direction of the housing 1, namely the live wire conductive sheet 2 and the neutral wire conductive sheet 2. The switch 4 is provided with a contact piece 41 corresponding to each conductive sheet 2. There is one limiting rib 42, and the limiting parts 23 on both conductive sheets 2 abut against the limiting rib 42. This reduces the number of components involved and simplifies the structure.

[0039] The grounding connection piece 3 extends along the length of the housing 1. Multiple grounding clips 5 are spaced apart along the length of the grounding connection piece 3. Each grounding clip 5 is U-shaped and includes a connecting arm 51 connected to the grounding connection piece 3 via a connector 6 and support arms 52 formed at both ends of the connecting arm 51. The support arms 52 protrude from the housing 1 for contact with the plug of the electrical appliance.

[0040] like Figure 6 As shown, the connector 6 includes a connecting post 61 and positioning parts 62 respectively formed at both ends of the connecting post 61. The connecting post 61 passes through the grounding connecting piece 3 and the connecting arm 51. The two positioning parts 62 press against the connecting arm 51 and the grounding connecting piece 3 respectively. The positioning parts 62 can be made of flexible material so that they can shrink and pass through the connecting arm 51 and the grounding connecting piece 3 when squeezed.

[0041] Preferably, a socket 12 can be provided on the wall of the housing 1, and the support arm 52 is located in the socket 12, which can be used to insert the plug of an electrical appliance.

[0042] In this embodiment, the shell 1 is formed by two half-shells 1a joined together.
