Embodiment
A kind of novel anti-shock socket, comprise the housing 6 that has jack on it, be provided with in the housing 6 by spring 3 and fixing zero line contact 1 and the live wire contact 2 of housing bottom, zero line contact 1 is fixed with live wire moving-conductor 11 by insulating element 15, also be fixed with the quiet conductor 10 of live wire in the housing 6, under the normality (when contact does not move), the quiet conductor 10 of live wire contact 2, live wire moving-conductor 11 and live wire has a pair of being separated from each other (promptly not contacting) between any two at least.
In this concrete enforcement, described zero line contact 1 and live wire contact 2 are " L " shape; Housing 6 middle parts are provided with insulating barrier 7, and the quiet conductor 10 of live wire is arranged at insulating barrier 7 bottoms (being under the normality, the contact below), and the end of live wire contact 2 and live wire moving-conductor 11 is positioned at insulating barrier 7 both sides; Zero line contact 1 and live wire contact 2 lower ends are provided with and are used for the elongated boss 4 that cooperates with spring 3;
Be provided with fixed lever 9 in the housing, zero line contact 1 and live wire contact 2 are provided with the fixing hole that cooperates with fixed lever 9; In order to prevent to be ejected again after plug 14 inserts, the jack place on the housing 6 is provided with by spring controlled plug 8, and plug 8 is a block rubber; For live wire contact 2 is contacted well with the quiet conductor 10 of the live wire on the insulating barrier 7 with live wire moving-conductor 11, the end face that live wire contact 2, live wire moving-conductor 11 contact with insulating barrier 7 can be provided with elastic sheet metal.
During use, live wire links to each other with the live wire moving-conductor, and zero line directly links to each other with the zero line contact, and when inserting without any object, state as shown in Figure 1; When inserting plug 14, two sheet metals of plug 14 back down plug 8 respectively, and zero line contact 1 and live wire contact 2 are promoted downwards, in this process, because be provided with insulating barrier 7 in the middle of live wire contact 2 and the live wire moving-conductor 11, live wire contact 2 can't be connected (being that power supply can't be connected) with live wire; When plug was all inserted, then zero line contact 1 and live wire contact 2 were pushed up to the quiet conductor of the live wire of insulating barrier 7 10 places, and live wire contact 2 is connected (being power connection) with live wire.
We analyze now, and this socket is a protection against electric shock how when having metal object to insert: 1. if there is a metallic foreign body to insert accidentally, if what insert is zero line jack, and then can be not dangerous; If what insert is firewire jack, live wire contact 2 is headed on and is moved down so, and zero line contact 1 is then motionless in the original place.It is also motionless in the original place so to be fixed in the live wire moving-conductor 11 of one by insulating element 15 and zero line contact 1, causes live wire contact 2 can't be connected with live wire at all, therefore can be not dangerous; 2. if having two metal objects successively to insert accidentally.According to convention, when we inserted second metal object, first metal object of relieving that hand can be very natural that is to say, is can be not adventurous generally speaking.Here we might as well do a hypothesis the worst, no matter promptly the order of Cha Ruing how, hand keeps in touch with metal object all the time.If the length that metal object is inserted is long, then below the metal object of inserting for the first time will be pushed up contact 1 or 2 the quiet conductor 10 of live wire of insulating barrier 7, second contact pushed up where power supply can not connected (promptly can be not dangerous) so.If the part of inserting is too short, then contact 1 or 2 will rest on insulating barrier 7 the quiet conductor 10 of live wire above, same second contact pushed up where power supply can not connected.That is to say, could connect circuit when having only length that two metal objects insert all identical with the length of plug metal film.In the ordinary course of things, getting an electric shock all is because accidentally, two metal objects is inserted two jacks simultaneously and the situation that causes getting an electric shock is few, and it is few especially that two metal objects are all inserted the length identical with the length of plug metal film.So use the utility model to cause the probability that gets an electric shock extremely low, we can regard it as fully can not event.Therefore in the ordinary course of things, the utility model can prevent careless electric shock fully.
A kind of novel anti-shock socket, comprise the housing 6 that has jack on it, be provided with in the housing 6 by spring 3 and fixing zero line contact 1 and the live wire contact 2 in housing 6 bottoms, zero line contact 1 is fixed with live wire moving-conductor 11 by insulating element 15, also be fixed with the quiet conductor 10 of live wire in the housing 6, under the normality (when contact does not move), the quiet conductor 10 of live wire contact 2, live wire moving-conductor 11 and live wire has a pair of being separated from each other (promptly not contacting) between any two at least.
Described live wire contact 2 and zero line contact 1 are bar shaped; Insulating element 15 is fixed in zero line contact 1 bottom, and the quiet conductor 10 of the live wire on the housing 6 is located at live wire moving-conductor 11 belows (under the normality), and live wire contact 2 is connected with lead 5 with live wire moving-conductor 11; Clamp plugs in order to insert the back at plug 13, preventing that plug from being ejected, the jack place be provided with by spring controlled plug 8, plug 8 is a block rubber; Zero line contact 1 and live wire contact 2 lower ends are provided with and are used for the elongated boss 4 that cooperates with spring 3;
In order to make symmetrical configuration, live wire contact 1 bottom fixed insulation parts 15 are fixed with zero line moving-conductor 13 on the insulating element 15, and zero line moving-conductor 13 belows are provided with the quiet conductor 12 of zero line on the housing 6; Zero line contact 1 top is connected with lead 5 with zero line moving-conductor 13.
During use, zero live wire is connected with the quiet conductor of zero line, the quiet conductor of live wire respectively, when inserting without any object, state as shown in Figure 2; When plug all inserted, the moving-conductor 11,13 of live wire contact 2 and zero line contact 1 bottom contacted with quiet conductor 10,12 on the housing respectively, then power connection; When having only a contact be depressed (supposing that this contact is the live wire contact), the zero line moving-conductor 13 of its below is contacted with the quiet conductor 12 of the zero line on the housing, this contact only has been to connect the effect of zero line and zero line contact, and itself does not connect with live wire at all; In like manner, if the zero line contact is depressed, worked to connect live wire and live wire contact, and itself is not connected with zero line at all.That is to say, contact whether with zero/live wire connect depend on fully whether another contact is depressed and correspondingly moving-conductor whether contact with mutually required quiet conductor, and it doesn't matter with itself.Therefore if when having metallic foreign body to insert, have only zero, when the live wire contact all is depressed and the live wire moving-conductor contacts respectively with the quiet conductor of zero line with the quiet conductor of live wire, zero line moving-conductor, zero/live wire just can be connected, insert long or too short metal object, power supply can not connected, so this socket can prevent to get an electric shock under general situation fully.
