Description

Technical Field

[0001] This utility model relates to the field of AC seats, specifically to a vertical AC seat. Background Technology

[0002] A television set is a device that uses electronic technology to transmit moving images and audio signals based on the persistence of vision and visual psychology of the human eye; it is also an important broadcasting and video communication tool. The basic system of a television set consists of three parts: image capture, transmission, and display.

[0003] Referring to patent application publication number 201822209067.2, a socket body is included, having a grounding pin, an L-line pin, and an N-line pin. The feature is that it further includes a yellow-green ground wire. The lower end of the grounding pin is connected to a grounding lug. One end of the yellow-green ground wire is integrated with the grounding lug, and the other end is connected to a lap portion. This lap portion is connected to the grounding screw hole of the power board. The lap portion is a screw lug, which is locked onto the grounding screw hole of the power board. The lap portion is a metal barb inserted into the grounding... At the screw hole, a yellow-green ground wire is used to electrically connect the grounding screw hole on the power board to the grounding pin of the AC socket. Since the cross-sectional area of ​​the copper wire inside the yellow-green ground wire is larger than the copper conductor area required for 1500A current withstand, there is no need to perform grounding testing, which can save safety testing costs. At the same time, it meets the 1500A grounding test requirements of the new IEC62368 regulation. This overcomes the fact that existing vertical AC sockets can only use the grounding copper foil of the power board to make the grounding screw hole and the grounding pin of the AC socket for electrical connection, which cannot pass the 1500A grounding test requirements of the new IEC62368 regulation.

[0004] In scenarios requiring vibration resistance and high heat dissipation, such as large-screen TVs, commercial displays, and outdoor advertising screens, vertical AC connectors are needed. Due to their vertical pin structure, vertical connectors provide higher mechanical stability in environments subject to vibration and impact (such as wall-mounted TVs or during transportation), reducing the risk of loosening.

[0005] The vertical structure, with its vertical pin design, can achieve higher connection density in a limited space, making it suitable for compact circuit board devices. The vertically mounted pins form a heat dissipation gap with the circuit board, which facilitates rapid heat dissipation and reduces the risk of poor contact caused by high temperature.

[0006] The horizontal connector reduces insertion and extraction stress through its parallel pin design, making it more suitable for indoor use scenarios with static conditions or slight vibrations, such as desktop televisions. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes a vertical AC seat to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] A vertical AC connector includes a plastic body, with a circular contact block on the inner wall of the plastic body, and pins on the contact points of the circular contact block. A positioning post is fixedly connected to the outer wall of the plastic body. The plastic body protects the internal components, ensures the mechanical strength and electrical insulation of the connector, and prevents external interference and damage.

[0010] Preferably, there are two positioning posts, and the two positioning posts are symmetrically arranged; the two positioning posts are used to fix the connector to the PCB board, providing a stable mechanical connection and ensuring the stability of the connector during use.

[0011] Preferably, there are two circular contact blocks, and the two circular contact blocks are symmetrically arranged; the two positioning posts are used to fix the connector on the PCB board, providing a stable mechanical connection and ensuring the stability of the connector during use.

[0012] Preferably, there are two positioning posts, and the two positioning posts are arranged vertically. By setting the positioning posts, a heat dissipation gap is formed between the vertically installed pins and the circuit board, and a part of the bottom of the plastic body is hollowed out, which facilitates the rapid dissipation of heat and reduces the risk of poor contact caused by high temperature.

[0013] Preferably, there are two circular contact blocks, with one end of each circular contact block contacting the plug to complete the transmission of electrical signals, and the other end connected to a solder pad. One end of the solder pad is connected to the circular contact block, and the connection part is petal-shaped. The purpose of setting the petal-shaped connection part is to increase the contact area, provide a reliable electrical connection, and ensure stable transmission of current or signals without attenuation.

[0014] Preferably, the other end of the solder pad is welded to the PCB board hole using a wave soldering process, and the solder pad at the PCB board hole position is arrow-shaped; by setting the solder pad in an arrow shape, it is easier to align with the board hole, improve the insertion efficiency, and avoid the risk of failure due to misalignment, while also strengthening the strength of the solder pad.

[0015] In the section where the solder pad meets the PCB hole, ribs are added to the solder pad. The ribs increase the strength of the solder pad and also facilitate slight friction with the board hole, thus enhancing stability.

[0016] Preferably, the plastic body is wrapped from top to bottom with a U-shaped stainless steel stabilizing sheet. The protruding clips of the plastic fit tightly with the corresponding gaps in the sheet. The stabilizing sheet and the plastic body extend out one end into a hole in the PCB board; this achieves the effect of strengthening and stabilizing the overall AC seat after welding. At the same time, the stainless steel surface is nickel-plated to improve corrosion resistance and wear resistance.

[0017] Preferably, the grooves and protrusions on the sides and ends of the stabilizing sheet are used to mate with the connecting male; this provides assembly positioning, ensures proper connection and fixation between components, and improves the stability of the connection.

[0018] 2. The beneficial effects of this utility model are as follows: 1. This vertical AC connector, through the vertical gap of the vertical connector, facilitates airflow and improves local heat dissipation, making it suitable for high-power TV boards or equipment requiring long-term operation. The vertically protruding structure of the vertical connector makes it easier to position and replace, making it suitable for industrial-grade TV equipment requiring frequent maintenance.
