Abstract
An electric socket (1) comprises a shutter (20) forms a first latch means, and is latched in a closing position which covers openings (15, 16) in the front wall (2) of a socket with a hook or a fixed stopping member, and first latch is made movable by an earth pin or a projection (4). Unlatching of the first latch is conducted by the insertion of the earth pin or the pin projection, and insertion operates a live pin (5,6) on a shutter so as to separate the shutter from the opening. Preferably, second latch operable with the live pin (5) and a neutral pin (6), or an arm edge (29) or a latching groove (31) is arranged, and the shutter is fixed to the closing position.
Description
The present invention relates to a kind of electrical outlets, this socket has at least two receptacle connectors, for usefulness and a lid of being connected with two or more pin contacts of plug, supply to cover the hole of inserting for plug base pin on the socket antetheca, thereby when plug is not plugged, cover wherein two contacts.
Usually the plug that provides is such: socket cover covers live wire hole and the neutral line hole on the socket, and the component socket lid that extends to the ground wire hole by means of its inclined-plane can move on to the position of opening.Earth pin affacts on the inclined-plane of parts when inserting, and socket cover is pushed away each socket aperture.When plug pulled out, spring then can make lid close.These socket covers are opened simply, as long as insert a probe (probe) in the ground wire hole.
The objective of the invention is to make this socket safer.Therefore, electrical outlets of the present invention has at least two receptacle connectors, for the usefulness that is connected with two or more pin contacts of plug, with a lid, in order to cover the hole on the socket antetheca for the plug base pin insertion, thereby when plug is not plugged, cover wherein two contacts, wherein, socket cover locks onto the position of closing by means of at least one first locking piece, first locking piece then locks by means of the grounding pin of plug or from the male member except plug live wire pin and neutral line pin that plug protrudes, wherein: at least one such locking component is made by first locking piece system, it stretches out from socket cover, grounding pin or male member are then laterally shifted socket cover onto a side, it is between live wire pin and the neutral line pin, thereby make locking piece break away from the constraint of retainer, described socket cover system makes and makes it have at least one lateral inclination part live wire hole on the antetheca and neutral line port lid are lived, and these one or more locking components partly stretch out from these one or more lateral inclinations, described socket cover then pushes the appropriate location by a spring assembly with it, described one or more lateral inclination partly is to form on second locking piece locks onto each arm of off-position, and second locking piece can work by means of the live wire pin and the neutral line pin of described plug.
Socket cover preferably has at least a lateral inclination part that live wire hole and neutral line port lid are lived, and wherein these one or more locking components partly stretch out from these one or more lateral inclinations, and socket cover then pushes the position of closing by a spring with it.For making socket cover safer, lateral inclination part itself can also be equipped with second locking piece, the pressure that second locking piece need be socket cover can be shifted to live wire pin and neutral line pin along a direction from grounding pin before affacts the lateral part simultaneously by means of live wire pin and the neutral line pin state that unlocks.
Say some embodiments of the present invention referring now to accompanying drawing.In the accompanying drawing:

Fig. 4 to 6 is the plane graph of the seen socket cover moving process of Fig. 1, and Fig. 4 is plug or pin first kind of state when not inserting, and Fig. 5 is the second kind state of the grounding pin of three-pin plug when inserting, and Fig. 6 is all pins the third state when inserting;
Fig. 7 is the perspective view of the socket cover of third embodiment of the invention;
Fig. 8 is a plane graph like socket cover and view Fig. 1 of Fig. 7;
Fig. 9 to 11 is plane graphs of the socket cover seen of Fig. 8, corresponds respectively to the moving process of the socket cover shown in Fig. 4 to 6.
The receptacle connector that the connection pin is used is not shown.
There is a socket cover 20 antetheca 2 belows in the socket, and the latter is locked in Fig. 1 and off-position shown in Figure 4 by means of first locking piece and a fixing retainer 22.First locking piece has the opposed locking component of a pair of formation hook-like part 21.Hook-like part 21 is opposite each other, forms the end sections of the flat muscle 23 of elasticity that stretches out from lateral inclination part 25, and when socket cover was closed, lateral inclination part 25 was under hole 15 and 16, and hole 15 and 16 is sealed.Lateral part or lock face 25 form on horizontal expansion arm 27.Arm 27 slightly is inclined upwardly to locking edge 29 usually.Locking edge 29 is locked in the lock slots 31 that forms on the inner surface of antetheca 2 adjacent perforations 15 and 16, forms second locking piece.
Hook-like part 21 is equipped with chamfered edge limit 19 and vertical chamfered edge limit 18.
When plug 3 inserted socket 1, grounding pin 4 affacted earlier on the chamfered edge 19 of hook-like part, forces hook-like part 21 to open.They have just left retainer 22, as shown in Figure 5.Then, on the sloping portion 25 that short live wire pin 5 and neutral line pin 6 affact socket cover arm 27, force the position of each arm and arm limit 29 40 place's dotted lines in moving down into Fig. 2.At this moment, unlock state and releasing slots 31 of limit 29. Pin 5 and 6 impels socket cover 20 to depart from hole 14 when further inserting, and hole 15 and 16 is opened, thereby make each pin enter hole 14,15 and 16 fully, as shown in Figure 6.When plug inserted fully, socket cover recovered its original shape, shown in the solid line among Fig. 2.This is to realize by means of the 2 aslope inner surfaces 36 of the antetheca shown in Fig. 3.
When plug pulled out, spring 34 pushed up back socket cover 20.Each arm or the wing 27 and hook-like part 21 lock again, and socket cover 20 is locked in the position that it is closed.
Fig. 3 A shows second embodiment, and this is the allocation plan that the socket cover with Fig. 3 changes a little, and its medi-spring 34 ' is embedded in the recess 35 that forms between the muscle 23 ' of hook-like part 21 ' and the center rib 32 '.This makes socket cover dispose compactlyer.
Be noted that and only establish a hook-like part 21 or 21 ', but do with regard to not establishing a pair of hook-like part effective like that like this.
Fig. 7 and 8 shows the 3rd embodiment, when wherein socket cover 120 works be along with first embodiment shown in Fig. 1 to 6 in opposite direction X open hole 115 and 116.Such configuration mode has some benefit, is about to below discuss.
The 3rd embodiment also has effect and form and the first embodiment similar recessed circle 150 shown in 50.The 3rd embodiment is better than first embodiment, and spring 134 is placed between three pin holes 114-116 fortunately, thereby disposes compactlyer.
More than three embodiment structure more known than prior art good, can not influence the unlatching of socket cover when the grounding pin on the socket cover has any damage fortunately.In addition,, and need not to overcome the socket cover spring and come the mobile socket lid, so when plug began to insert, frictional force was little because the side of grounding pin do not lock.Want the mobile socket lid, need insert all three pins simultaneously.For example, when not having grounding pin or similar male member, member 21 or 121 still can lock socket cover.If live wire pin or neutral pin are lost, then arm 27 or 127 keeps lock-out state.If plug for example two pin plug of Continental Europe standard, and the stressed for a certain reason and state that unlocks of locking component 21 or 121, then concave region 50 or 150 stops socket covers to vertically move.Socket cover and locking component thereof are constituted an integral body, can reduce to cost minimum.Requisite in the socket cover device is spring, and socket cover will have locking device.Remaining any parts, retainer 22 or 122 for example all is molded into the part of jack assemblies.Therefore, the assembling of socket in manufacture process is also simple, and material benefit.In addition, not as the situation of many previous socket cover devices, require high from the fabrication tolerance of said structure.
