Description

Technical Field

[0001] This utility model belongs to the field of power socket technology, specifically relating to a DC power socket. Background Technology

[0002] The socket for DC power supply consists of a horizontal socket, a vertical socket, an insulating base, fork-shaped contact springs, and a directional keyway. Two fork-shaped contact springs are positioned in the center of the base, arranged horizontally and vertically without being connected. One end of each fork-shaped contact spring is a wiring port exposed on the top surface of the cylindrical base, for connecting the input power cord or cable. The other end of the fork-shaped contact spring consists of two interconnected elastic arms on the base, located within the insulating base socket in the direction of the DC plug insertion, supplying power to the computer monitor for normal operation.

[0003] In existing technologies, the positive electrode is usually formed by riveting a positive copper pillar and a terminal, and the contact area of ​​the negative electrode is small, which means that the power socket can only pass through a voltage of 12V and a current of about 5A. If a large current passes through, the pins of the power socket are prone to burnout due to excessive current. Utility Model Content

[0030] like Figures 1 to 7 As shown, a DC power socket includes:

[0031] The system comprises a substrate 1 with a through-hole 103 at its center; a positive electrode needle 2, which is fitted into the upper half of the mounting hole 103; and a snap-fit ​​structure, which is located between one side of the substrate 1 and the positive electrode needle 2. The snap-fit ​​structure includes an insertion hole 104 and a necking groove 201. The insertion hole 104 is located on one side of the substrate 1 and extends into the mounting hole 103. The necking groove 201 is located on the positive electrode needle 2. A card 3 is inserted into the insertion hole 104, and the card 3 has a slot 301. When the positive electrode needle 2 is fitted into the upper half of the mounting hole 103, the end of the card 3 with the slot 301 is inserted along the insertion hole 104, so that the slot 301 on the card 3 is fitted into the necking groove 201, thereby stabilizing the positive electrode needle 2 in the mounting hole 103. Furthermore, the positive electrode needle 2 adopts an integrated structure, abandoning the traditional positive electrode copper post and terminal riveting structure.

[0032] The outer shell 4 is U-shaped. The upper half of the two side walls of the base 1 are provided with a fastening groove 101. The two side walls of the outer shell 4 are provided with a flap 401. The edges of the two side walls of the outer shell 4 are provided with a hook 402. The bottom end of the side wall of the base 1 with the insertion hole 104 is provided with a boss 107. The bottom of the outer shell 4 is provided with a notch 403. After the card 3 is inserted into the insertion hole 104, the outer shell 4 is fastened to the base 1 by moving one end of the outer shell 4 with the hook 402 along the side wall of the base 1 with the insertion hole 104. The flap 401 is located in the fastening groove 101, the hook 402 is fastened to the side wall of the base 1 away from the insertion hole 104, and the boss 107 is fastened to the notch 403. This makes the outer shell 4 stably installed on the base 1, so that the outer shell 4 covers the insertion hole 104 and the card 3.

[0033] The negative electrode annular sleeve 5 has two hook plates 501 facing each other on its top and two hanging holes 105 facing each other on its base 1. The hook ends of the two hook plates 501 pass through the corresponding hanging holes 105 and are fastened to the edge wall of the opening of the hanging holes 105, thereby enabling the negative electrode annular sleeve 5 to be hung in the lower half of the mounting hole 103.
