Abstract

The utility model discloses an element of an electrical socket, in particular to a safety element of an electrical socket which is used for preventing the user from accidentally contacting the conductive part of the socket outside the socket and avoiding the accident of electric shock. The safety element of an electrical socket is composed of a screening element and a compression spring. The safety element of an electrical socket is arranged in the panel of the electrical socket and the casing. The safety element of an electrical socket is characterized in that the safety element of an electrical socket makes use of the slide of the slant surface of the screening element bearing unidirectional elastic acting force and the end surface of a pin to complete the screening and opening function. The safety element of an electrical socket has the advantages of simple structure, convenient manufacture, reliable work and long service life.

Description

Safety element of electrical socket

The utility model is parts of electrical outlets.

The electrical outlets safety protection mechanism is used to prevent that the end user from contacting with the accidental of current-carrying part of socket beyond socket, thereby avoids the generation of electric shock accidents.

Adopt the electrical outlets of safety protection mechanism; when the free state of inoperative; L on the socket, the N utmost point are under the bridging effect of safety protection mechanism; when the object of any tiny similar push rod is disclosed into any jack; or when adopting burnisher clean surface such as hairbrush; covering is in closure state, thereby reaches the purpose of the unlikely electric shock of protection end user.When the latch of corresponding plug inserted socket, compressing when two inclined-planes of covering are subjected to two pins and moving finally was in open mode, thereby guarantees that plug enters socket, the realization positive engagement.When pulling the plug out of the socket, covering is the effect of spring by compression, returns to shielding status rapidly.

The utility model is made up of covering and two parts of spring.Entire mechanism is installed among the electrical outlets, this socket have can with the electrode of the latch coupling of plug, have an insulation crust panel simultaneously, have window on it by latch.

The application of this mechanism is described below as an example:

Fig. 1 is the socket panel that this mechanism is housed.

Fig. 2 is the typical structure of covering.

Fig. 3 be this mechanism respectively (I) free state (II) when latch enters window state (III) latch finish the work schematic diagram of when engagement state.

In the special-shaped cave of panel 1, the covering 3 and the compression spring 5 of this mechanism is installed respectively, an end of spring is against the end face of groove, and the other end heads on covering, relies on the elastic force effect, and covering is pushed into make position.When the latch 7 of plug inserted by the window on the panel 2, the end face of latch contacted with inclined-plane 4 on the covering, and along with the propelling of latch, the latch end face is along the slip of covering inclined-plane, and covering moves to opening direction.When covering moved to the latch end, the window on the panel was opened fully, and latch can continue to insert the electrode 6 of socket 8, positive engagement with it.When plug was extracted from socket, the latch end face skidded off along covering inclined-plane 4, relied on the elastic force of spring 5, made covering be returned to the origin-location along chute, kept shielding status.

Characteristics of the present utility model: 1. simple in structure, easily manufactured, only finish the function of whole mechanism with two parts; 2. reliable operation because simple in structure, more successfully reduce and causes disturbing factor stuck or can not the return fault; 3. the life-span is long, when plug inserts, because two latch end faces contact with two inclined-planes of covering respectively simultaneously, reduced the friction of contact site, and the manufacturing of covering employing abrasion-proof insulating material, effectively prolonged service life.

Claims

1. electrical outlets safety protection mechanism, entire mechanism is installed among the electrical outlets, this socket have can with the electrode of the latch coupling of plug, have an insulation crust panel simultaneously.Feature of the present invention is that safety protection mechanism is become with compression spring set by covering, utilizes the inclined-plane of the covering of bearing unidirectional elastic acting force and the slip of latch end face to finish covering of covering and open function.

2. according to the socket with safety protection mechanism of claim 1, it is characterized in that: the panel window by latch is three prolate holes, and wherein L, N two holes have the safeguard protection effect.

3. according to the socket with safety protection mechanism of claim 1; it is characterized in that the covering that adopts high-abrasive material to make; two contact inclined-planes contact with two latches simultaneously and slide, and open simultaneously and cover two jack windows.
