Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a welding structure of a switch socket. Background Art

[0002] A socket is an electrical device that provides a power interface for household appliances, and a switch socket with a power on / off function is widely used due to its safety. A switch socket generally includes a housing, one or more socket positions are arranged on the top of the housing, a corresponding socket assembly is arranged inside the housing and below each socket position, and also includes a power switch and a wiring assembly arranged in the housing, the wiring assembly includes a live wire conductive sheet, a neutral wire conductive sheet and a grounding conductive sheet electrically connected to the L pole pin, the N pole pin and the E pole pin of each socket assembly respectively, the first pin of the power switch is electrically connected to the live wire conductive sheet, and the second pin is electrically connected to the live wire of the power line, and the neutral wire conductive sheet and the grounding conductive sheet are electrically connected to the neutral wire and the ground wire of the power line respectively.

[0003] The welding structure of the power switch and the live wire conductive sheet of an existing switch socket is as follows: Figure 1 and Figure 2 As shown, the live wire conductive sheet 1a is in the shape of a strip plate and is laid flat under the first pin 3a of the power switch 2a. By inserting solder into the connecting hole 4a of the first pin 3a, the first pin 3a of the power switch 2a can be welded to the live wire conductive sheet 1a.

[0004] However, the welding structure of the existing switch socket has the following technical problems: when the high-temperature solder is inserted into the connecting hole 4a of the first pin 3a, due to the gap between the upper and lower surfaces of the first pin 3a and the live wire conductive sheet 1a, the high-temperature solder with good fluidity can easily flow into the gap, and even overflow to the lower surface of the live wire conductive sheet 1a due to the excessive flow rate, and not much solder remains in the connecting hole 4a of the first pin 3a; the thickness of the solder flowing into the gap between the upper and lower surfaces of the first pin 3a and the live wire conductive sheet 1a is not controllable, so that the first pin 3a and the live wire conductive sheet 1a, which should be in surface contact, may be connected together only by point-shaped solder, and the connection is very unreliable. The two are easily separated during transportation or impact, resulting in cold soldering or tin slag falling, and the solder overflowing to the lower surface of the live wire conductive sheet 1a may also fall tin slag. Cold soldering will cause local function failure of the product, and tin slag will cause abnormal noise or even short circuit, all of which will affect product performance. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a welding structure of a switch socket which is not prone to false welding and tin slag falling.

[0006] The technical solution of the utility model is: a welding structure of a switch socket, including a power switch and a wiring assembly, the wiring assembly includes a conductive sheet, a first pin of the power switch is electrically connected to the conductive sheet, a second pin of the power switch is used to be electrically connected to the live wire of the power line, the conductive sheet includes a body and a welding portion arranged on the body, the welding portion is supported above or below the first pin of the power switch, and the welding portion is also provided with a protrusion protruding into the connection hole of the first pin of the power switch.

[0007] After adopting the above structure, the utility model has the following advantages:

[0008] The welding structure of the switch socket of the utility model is provided with a bump on the welding part which protrudes into the connection hole of the first pin of the power switch, which not only increases the welding area, but also has a tension effect on the solder inserted by the bump, so that the flow speed of the solder is slowed down and most of the solder can be adsorbed in the bump and the connection hole, while the flow to the gap between the first pin and the upper and lower surfaces of the conductive sheet is reduced, and it is more difficult to flow to the lower surface of the conductive sheet; since most of the solder remains in the bump and the connection hole, the connection between the first pin of the power switch and the conductive sheet is very reliable and it is not easy to have a cold solder joint; since the solder remaining in the gap between the first pin and the upper and lower surfaces of the conductive sheet is very small, and if there is basically no solder on the lower surface of the conductive sheet, it is not easy to drop tin slag; therefore, the above-mentioned arrangement makes it difficult for the first pin of the power switch to have a cold solder joint and drop tin slag after welding with the conductive sheet, thereby making the product performance more reliable.

[0009] Preferably, the soldering portion has a first flat surface that fits with the top surface or bottom surface of the first pin of the power switch, and the bump is arranged on the first flat surface. This arrangement can make the soldering portion fit more closely with the first pin of the power switch, so that the solder is less likely to flow into the gap between the first pin and the upper and lower surfaces of the conductive sheet.

[0010] Preferably, the convex block and the welding part are integrally formed, which can make the combination of the convex block and the welding part more reliable and more convenient to process.

[0011] Preferably, the welding part is plate-shaped, and the protrusion is formed by cutting a section inward from one side of the welding part and bending it at the root. This arrangement makes the formation of the protrusion more convenient.

[0012] Preferably, a notch is formed between the cut side of the welding portion and the bump, and the notch is at least partially located in the connection hole of the first pin of the power switch. This arrangement further increases the welding area between the bump and the connection hole, making it easier for solder to be adsorbed in the bump and the connection hole.

[0013] Preferably, the body is arranged perpendicularly to the welding part, and the body has a second flat surface that fits the side of the first pin of the power switch. This arrangement can use the welding part to abut against the top or bottom surface of the first pin of the power switch, and use the body to abut against the side of the first pin of the power switch, so that the first pin of the power switch can be quickly positioned to the welding position of the welding part, and the welding is easier and more reliable.

[0014] Preferably, the welding part is formed integrally with the body, which can make the welding part and the body more reliable and more convenient to process.

[0015] Preferably, the body is in the shape of a strip plate, and the welding portion is formed by bending a lateral wing arranged at one end of the body. This arrangement makes the formation of the welding portion more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, the conductive sheet 2 is a live wire conductive sheet, and the welding portion 6 is supported above the first pin 3 of the power switch 1. The conductive sheet 2 may be in contact with the first pin 3 of the power switch 1 before welding, or may not be in contact with it. The welding portion 6 is also provided with a protrusion 7 that protrudes into the connection hole 11 of the first pin 3 of the power switch 1; for ease of understanding and description, Figure 3 and Figure 5 Other components of the switch socket are also illustrated; the wiring assembly generally also includes a neutral wire conductive sheet 12 and a grounding conductive sheet 13.

The neutral wire conductive sheet 12 and the grounding conductive sheet 13 are also respectively used to electrically connect to the neutral wire and the ground wire of the power line.

[0027] The welding portion 6 has a first flat surface 8 that fits with the top surface or bottom surface of the first pin 3 of the power switch 1, and the bump 7 is arranged on the first flat surface 8; the main body 5 is arranged perpendicular to the welding portion 6, and the main body 5 has a second flat surface 10 that fits with the side surface of the first pin 3 of the power switch 1, and the first flat surface 8 is perpendicular to the second flat surface 10.

[0028] The protrusion 7 is integrally formed with the welding portion 6; the welding portion 6 is in the shape of a plate, and the protrusion 7 is formed by cutting a section inward from one side of the welding portion 6 and bending it at the root; a notch 9 is formed between the cut side of the welding portion 6 and the protrusion 7, and the notch 9 is at least partially located in the connection hole 11 of the first pin 3 of the power switch 1; the welding portion 6 is integrally formed with the body 5; the body 5 is in the shape of a strip plate, and the welding portion 6 is formed by bending a lateral wing arranged at one end of the body 5; in this embodiment, the body 5 of the conductive sheet 2 is made of a copper plate, and the upper and lower surfaces of the copper plate are straight.
