Abstract

A device to build up and break off internal electrical connection from outside of an electronic device is provided. A connecting terminal that provides external electrical line connection is implemented in an interlaced manner at the site for external connection in the mainframe. The adjacent terminals are connected and disconnected directly through conducting parts to and achieve built-up and break-off an electrical loop. Because the electrical terminals are installed inside the mainframe, users and maintainers don't have the risk of touching the dangerous voltage so as to and ensure their safety.

Description

554593 A7 ___ ___ B7_ V. Description of the Invention (丨) The present invention relates to a device for establishing and disconnecting an internal electrical connection outside an electronic device, especially a high-security and low-cost electrical connection device. In accordance with safety regulations (such as the European standard EN60950: Safety of Information Technology Equipment), in order to avoid the risk of electric shock, the protection of user accessible areas (EN60950 2. l. 1

Protection in Operator Access Areas). In the regulations, the circuit directly connected to the mains is called the primary circuit (

Primary Clrcuit: EN60950 1 · 2 · 8_2), and the circuit that is not directly connected to the mains is called the secondary circuit (SecOndaiT Circuit; EN60950 1.2.8.3). The power of the secondary circuit is usually passed through a transformer, transformer The current generator or equivalent isolation device is used to generate it, and it may also come from the battery isolated from the primary side. Safety regulations require that a more common type of design that allows users to access the area is a safety low voltage circuit (SELV Circuit: Test 6907.1.2.8.6 Safety Extra Low Voltage Circuit), which is subject to reinforced insulation (reinforced lnsu) : Iati ON) and other specially processed secondary-side circuits, so the design requires high insulation level and complicated. Another type that is more commonly used is to use the mechanism design to prevent users from directly touching the primary circuit. Women's regulations require these designs to maintain a minimum safe distance between the accessible area and the primary circuit to prevent users from having The danger of electric shock also complicates the design of the mechanism. s Today's electronic devices 'in order to facilitate maintenance, most of them will adopt a modular design, and for user convenience or in some non-stop applications' requirements, electronic devices are required to have hot-swappable modules The standard of wood paper is applicable to China National Standard (CNS) A4 specifications & 〇X 297 public love) " (Please read the precautions on the back before filling this page) ^. II AW .--------- ------- r________ A7 l. Description of the invention (2)

When designing a module that can be hot-swapped, in order to comply with the aforementioned safety regulations, and to design the electrical connection with the host, you must allow users or maintenance to worry about it. For example, to prevent the continuous charging of computer equipment from power outages: keep the host computer running continuously when replacing aging batteries or faulty modules, how to handle the battery or module and the circuit on the human side (and The electrical connection between the mains-connected circuit) is the key to the safety of the user when replacing the battery or module. Generally, there are two types of connection methods for replacing the battery or module: 1 in the uninterruptible power system A low-voltage transformer is added in the middle, so that the battery or module is set on the safe low-voltage side of the uninterruptible power system to ensure that the battery or module is replaced at any time and has safety. 2. Will—Minimum safety with reinforced insulation requirements The distance between the connectors is set between the battery or module and the primary circuit of the uninterruptible power system to realize the function of electrical disconnection and connection, so as to ensure the safety of the hot battery replacement process. The additional circuit for power conversion is added, which occupies constant system volume, and the latter is expensive due to the design of the safety compliance knowledge and insulation device in the connector. Please cooperate with the seventh figure As shown, the connection-(50) is connected to the battery (6 :) and the motherboard (62), respectively. When in use, it needs to be connected by the plug (5) and the socket (5 2). r The battery (6 1) is disconnected or connected to the main board (6 2); therefore, when the battery is replaced, the user still needs to touch and insert the connector (50) directly with his hand, so when the connector is used If the safety product is not qualified, it may cause the user to directly contact the dangerous voltage and be safe (please read the precautions on the back before filling this page) Φ --------- ^ I --- -Applicable to China National Standard (CNS) A4 specification (2i0x 297 mm) for clothing and paper scales. 5. Concerns on the description of the invention (Master). Lian: It can be known that there are still many Disadvantages, therefore, the design should be improved step-by-step to solve the four questions, so as to improve the safety in use. ^ To this end, the main purpose of the present invention is to provide a method of high safety and convenient electrical connection, and cooperate with this— The electrical connection device of the method is even more: * Many features such as low installation and low cost make it replace the current practice- The electrical connection protection circuit or the responsible connector on the side of the dangerous money does not take up space. The main technical means used for the above purpose is to make the electrical connection inside the host of the electronic device and connect it to the primary circuit externally. The point position 'is staggered with electric wires for external electrical connection lines, while the point' allows adjacent endpoints to be connected / disconnected directly through the conductor to establish / disconnect electrical circuits, because the electrical endpoints are all located on the host Inside, the user connects or disconnects adjacent endpoints by controlling the conductive parts to avoid direct contact with the dangerous electrical dust endpoints, thereby greatly improving the safety of the user. Another object of the present invention is to provide a convenient use from the outside. The conductive member for controlling the electrical connection of adjacent terminals inside the host of the electronic device is provided with a plurality of independent electrical conductors 'each conductive body is disposed on an insulating body and corresponds to the adjacent end point' when the conductive body contacts the interior of the host In this case, each conductor will electrically connect the adjacent terminals, otherwise, the electrical connection of the adjacent terminals will be disconnected; therefore, the user only needs to touch the insulation body without Dangerous direct contact terminal voltage of the internal host. The purpose of the present invention is to make the additional module circuit compatible with the low-security 5 wood paper standard applicable to the Chinese National Standard (CNS) A4 specification (21 (^ 297 公 | — 554593 A7) Fifth Figure Sixth Figure Seventh Figure Five 、 Explanation of the invention ('Wire electrical connection is connected to the host, because the front electrical connector is set at the end point between the host and the module circuit, once the control electrical connector is disconnected from the main machine / ,,, and other modules After the electrical connection of the circuit, the external module circuit will be disconnected from the dangerous voltage terminal of the host and become insulated.
