Description

socket structure

The invention relates to a socket structure, especially an invention that the ground wire conductive sheet of the socket can adapt to ground wire pins of different shapes. After long-term use, the ground wire conductive sheet of the socket can maintain the clamping force and working temperature that meet the specifications. .

Countries have certain regulations on the clamping force of the conductive sheet of the power socket and the thickness of the plug pins. Taking the Republic of China as an example, when the Bureau of Standards and Inspection (BSMI) of the Ministry of Economic Affairs implements the National Standard (CNS) test for power socket products, it requires The conductive sheet of the socket still needs to maintain a certain clamping force after a certain number of times of use, so as to avoid heating up due to poor contact between the prongs of the plug and the conductive sheet of the socket. Taking live wire and neutral wire as an example, the national standard stipulates that the thickness of plug pins must be between 1.4 mm and 1.6 mm, and the clamping force of the conductive strip of the socket must be kept above 5 Newtons, and after the plug pins are inserted into the conductive strip of the socket and powered on, the The working temperature must be kept below 45°C. In practice, when the national standard testing unit performs the test for this certification, the plug pins with the upper limit of the thickness of 1.6 mm will be reciprocated on the conductive sheet of the socket for 5,000 times, and then the plug pins with the lower limit of the thickness of 1.4 mm will be reciprocated. Insert the conductive piece of the socket, test the clamping force and working temperature of the conductive piece after electrification, and whether it meets the requirements of the above-mentioned national standards. If the clamping force of the conductive sheet of the socket has been elastically exhausted under the reciprocating insertion and extraction of the plug pins with the upper limit thickness of 1.6 mm, when the plug pins with the lower limit thickness of 1.4 mm are inserted, the clamping force cannot meet the requirements of the national standard. , this place will also cause the working temperature to rise due to poor contact, causing the working temperature to fail to meet the requirements of the national standard.

In the Patent No. M375345 announced by the Republic of China, the disclosed conductive sheet has two first clips, a first clip is defined between the two first clips, and one of the first clips is selected for side stamping An ear piece is provided, and the two ends of the ear piece are connected to the first clamping piece, and a second clamping portion is defined between the ear piece and the first clamping piece. The prongs of the plug can be inserted into the second clamping portion from the front of the socket, and the prongs of the other plug can be inserted into the first clamping portion from the side of the socket, so that the plug can be inserted and pulled out from the front and side of the socket. However, the structure of the second clip part disclosed in the above-mentioned No. M375345 patent case lacks the elasticity of strain. In order to pass the test of the above-mentioned national standard, the gap of the second clip part must be able to meet the requirements of plug pins with a thickness of 1.4 mm. , but if the user uses a plug pin with a thickness of 1.6 mm, the second clip will generate a huge clamping force, making it difficult to pull out the plug.

In order to comply with the national standard, a number of conductive strips of the socket have been added with a strain-elastic structure, which can withstand repeated insertions and insertions of the plug pins and still maintain good clamping force. Please refer to the seventh figure and the seventh figure A, which shows a power socket structure with a set of three-hole sockets on the front and a set of two-hole sockets on the side, and a set of switches F to control the power supply. The conductive sheet of the socket is set in the form of a clip. The clip includes an enlarged section A and a clamping section B. The enlarged section A can endow the clamping section B with a certain clamping elasticity, even if the thickness is 1.6 mm. After repeatedly pulling out and inserting the pins of the upper limit value, the clamping section B can still provide sufficient clamping force for the pins of the plug pins with a thickness of 1.4 mm and keep the working temperature in line with the requirements of the above-mentioned national standards. That is, for the flat plug pins of the live wire and the neutral wire, the above-mentioned conductive sheet including the enlarged section A and the clamping section B can make the clamping force and working temperature of the conductive sheet comply with the national standard. But for the ground wire pin of the plug, because the ground wire pin is not in a flat shape, it is difficult to fully meet the national standard for the clamping force and working temperature of the ground wire conductive sheet only relying on the structure of the above-mentioned enlarged section A and clamping section B. specification.

Please refer to the eighth figure, the ground pin G of a common plug has a circular cross section, and most of them are hollow circular. Please refer to the eighth figure A, there is also another form of ground pin H, and its section is U-shaped. However, no matter the circular ground pin G or the U-shaped ground pin H, they all conform to the national standard of the Republic of China. Please refer to FIG. 8B. From a cross-sectional view, the length D1 and width D2 of the U-shaped ground pin H are the same as the diameter D3 of the circular ground pin G. The maximum size of the circular ground pin G in the X direction and the Y direction shown in the figure is the diameter D3; but the maximum size of the U-shaped ground pin H in the Y direction is located on both sides of the X direction, that is, The position of the U-shaped line segment.

Please refer to Figures 9 and 10. When the circular ground pin G is inserted into the ground slot I, the circular ground pin G can be tightly pressed against the ground clamp C on the opposite side. The curved surface enables the ground wire slot I to expand moderately and maintain proper clamping force. When the U-shaped ground wire pin H is inserted into the above-mentioned ground wire slot I, the arc surface end of the U-shaped ground wire pin H can reach the arc surface of one of the ground wire clips C, and the U-shaped ground wire pin The flat end of H is against the edge of the arc surface of another ground wire clip C, and the ground wire clip C can still provide proper clamping force, but because the flat end of the U-shaped ground wire pin H is not controlled by another The center of the arc-shaped surface of the ground clip C is in contact, so that the expansion distance W5 of the ground slot I is greater than the expansion distance W4 of the circular ground pin G. When the U-shaped ground wire pin H is inserted for a long time, the ground wire slot I will be over-expanded, resulting in elastic fatigue. At this time, if the circular ground wire pin G is replaced, the ground wire clip C will not be able to The round ground pin G provides clamping force within specification.

At this time, the ground wire slot 71A is extended by a distance of W3, which is the distance between the inner surface of the first clip 72A and the inner surface of the second clip 73A in the Y direction. The mutual distance at the end positions. When the U-shaped ground wire pin 10 is inserted into the ground wire slot 71A, the arc surface end of the U-shaped ground wire pin 10 is against the arc-shaped first contact surface 7211A of the first clip 72A.
