SA111320143B1 - An Electrical Socket With a Shutter Mechanism for an Electrical Connector - Google Patents

Abstract

Abstract: The electrical socket includes a shutter mechanism to prevent socket misuse by preventing insertion objects that are attached to electrical terminals without a properly configured plug. The closure consists of two main components, the first requires insertion earth pin so that it moves to the relative position with respect to the second in which relative sliding motion is permitted, then the second member may move to expose other terminal units by inserting the pins The other terminals by insertion other pins. If pins inserted into the neutral and electrified terminals are inserted while the first member is in the initial position, the second member rocks or pivots to the position where the member prevent relative sliding movement. Thus, the terminals remain covered by the second member preventing connection. Figure 2a

Description

An electrical socket with a shutter mechanism for an electrical connector Full Description Background The invention relates to an electrical socket with a shutter mechanism for an electrical connector. The electrical socket in Britain includes three terminal units 016 - three terminals © in which the pins corresponding to the plug may be inserted. electricalal supply clive neutral and | To ground A provides the closures that led are intended to prevent misuse by inserting objects into the insertion objects and neutral before making the earth connection directly 0 0 06 p. The mechanism requires the earth pin plug before the neutral and Jive terminals are exposed to be inserted before the plug before neutral and Jive terminals are exposed. -driver or other inappropriate object in the electrified terminal before earth connection made .terminal before earth connection made 1 on Af if it is found that some of the existing closing mechanisms are not completely infallible complete. Because of the role in these current mechanisms; May thwart the safety feature leading to possible harm to the person exposed to the socket in order to misuse it through electrical -shock General description of the invention

Tuck back the present invention in order to provide 4401 with an improved closing mechanism. Provided here lak to the invention electrical socket comprising incorporating several plurality electrical connectors that are meant to be accompanied by conforming conductors in use and the closing mechanism To prevent contact with electrical connectors © including the first member adjacent to the unit: the movable first terminal and accompanying the connector to the terminal unit and from the initial position in order to confine position And the second member, the second member, is in the first initial position covering the second terminal, at least in order to prevent the connection of the conductor that engages the second member with the first member. In a sliding way when positioned in the retracted position to allow relative movement between them in order to allow attachment to one peripheral unit on JBI and to be able to pivot under the action of the connector provided that it moves to be associated with at least one peripheral unit when it is the first member member 115 is in a first position where the member aligns with the first member in order to prevent the relative sliding movement 0 between them in order to keep the second member in the position covering at least one peripheral unit. The current type of mechanism is more than tampered with from the arrangements of the previous method and is simpler and more suitable for manufacturing. Furthermore it; Inserting the first screw does not open the other terminal. This is required to be used at the specified location as well. “0 A BRIEF EXPLANATION OF THE DRAWINGS The specific representation of the invention will now be described “by representation only” with reference to the accompanying drawings which:

Figure 1 shows a three pin plug and a socket according to the invention; And figure number? Displays the shutter mechanism of the socket shown in Figure 1 in various operational states as shown in Figure 1. The plug supplies 1 socket according to the invention related to supplying main lines shown in line Connected mains supply shown in broken circuit circumference Typically (Typically socket) will determine the position of the plug in or on the wall surface of the building Wall surface building 1 socket has three holes of ? 4000 in das) .front face plate ll 1 upper hole is aligned with the internal terminal connected to earth 1 supply and the holes are lined up 1” holes and 4 with terminals connected live and neutral [06002. For the connect appliance © tools to be connected to the power supply; The plug 6 which has three screws 5A ¢ V three pins 4 ve and lined up with the socket and the pins inserted and pushed into the holes Jad operates the insertion of the screws into the holes The closing mechanism is in the method described later. Displays a number? Internal components socket 1. The internal components socket in Figure X shows the socket with the cover plate removed and the internal components at their initial position before insertion pins plug in order to understand the operation of 0 guidance; The arrow labeled arrow 01 shows the marking that the plug is inserted into the socket from the position above the socket The plug closing mechanism includes the first members socket shutter Mechanism comprises first and second 11 and AY ‏

VY three molded arms 511 and 0 complementary comprises 11 outer arms and Yo latches include 11 latches and 17 at its edges. V€ inner arm comprises 1 earth pin ramping surface. 11 comprises earth pin ramping surface as the plug is inserted along the direction 010 along the direction 1 earth pin On the ramp surface, YA, and the first member, member 1, is pushed in the direction of the arrow 01 in the direction of the arrow at the level of the major face socket 1806 m. This verb is shown again in a simplified form of degree Si in the side view of the form of the number LY locating the first member 11 first member in a sliding way in 13 article in order to facilitate smooth movement. The space is installed to confine and restrict movement as required. Motion progressively detects ground terminal 71 to allow electrical connection by the earth pin 1 as is

Shown in Figure No. C. In the case shown in Figure 7C, it will be seen that the latches 11 seen latches and 117 have been moved to the position overlying arms of the second latching member. 11 latching member 0 includes the second member VY second member two arms, YY two arms, and YY, and corresponds to the subtending transverse arm 7. It determines its position within the niche in the cover plate in the initial position Cus the ramped ramps YO ends and 1? located at the connection point between the arms YY arm and YY and the transverse arm Y¢ transverse arm covering neutral live terminals 0 and electrified YY and YA The 11 second member is installed in the porthole to contain two possible modes of motion The first mode of motion occurs when the mechanism is in the condition shown in Figure 7c where the ground pin is fully inserted and engaged

The first member, 11 first member, with the second member, when shrinking with this overlap, leads to inserting the screws. Insertion neutral and electrified <A live pins 9 to engage them with the ramping surfaces of the Yo ramping surfaces and the YT insertion leads to the sliding movement of the second member in the socket plane as indicated by the arrow mechanism Al Moallem © 179 Until the until neutral and fully electrified terminal units are displayed as shown in Figure Y d. These phases are Ble on a normal mode operation which allows correct insertion of the P:M plug. The mechanism prevents abuse in the manner described below. Figure AY shows the abuse case. In this other mode of motion the second member 11 second member 0 will appear. In Figure No. ?E, it will be seen that the earth pin did not enter, and that the first member does not overlap with the second member, VY (see also side view figure? And the). in this position; Member 11 is able to pivot. This causes the YY YY arms to move upwards to flank ends 11 and 117 of the first member. Therefore, it prevents relative sliding movement. 0 Neutral and live terminals keep 71 and YA covered with Yo ramping surfaces and .Y1 accordingly; The connection of the neutral or direct terminal units to the current misuse operation that led does not enter the earth pin is prohibited. At “0 this position; Relative sliding movement is possible to allow revealing neutral and live terminals as shown in Figure ? Dr..
