Abstract

The utility model discloses a safe socket, which comprises a panel, the L, N pole protective door and ground wire protective door arranged on the panel, and a spring used for protecting the returning of the door; wherein, the ground wire protective door is separate from the L, N pole protective door; the L, N pole protective door slides towards the inlet of the ground wire; the sliding direction of the ground wire protective door is roughly vertical to the sliding direction of the L, N pole protective door; the returning spring is respectively arranged in the square grooves of the ground wire protective door and the L,N pole protective door. The ground wire protective door of the utility model is roughly vertical to sliding direction of the L, N pole protective door. As the protective door can slide to different directions, and the sliding range basically utilizes the space available in the socket, the volume of the whole socket is small, completely meeting the demand for the microminiaturization of the socket volume.

Description

A kind of safety socket

Technical field

The utility model relates to a kind of socket, is the improvement technology of socket protective door specifically.

Background technology

At present, people are in order to make socket when not using, and avoid pointing inserting causing the generation of getting an electric shock in the receptacle sockets, thereby have designed various shutters, more common a kind of be the integral type shutter.The major defect of this shutter is that the size of shutter glide direction is bigger, thereby has increased the volume of socket.

Summary of the invention

It is little that the purpose of this utility model provides a kind of volume, the safety socket that serviceability is good.

The utility model is achieved through the following technical solutions the object of the invention.

A kind of safety socket; comprise panel; be positioned at L, N utmost point shutter and the ground wire shutter of panel; and be used for the spring that shutter resets; it is characterized in that: ground wire shutter and L, N utmost point shutter are disconnected from each other; L, N utmost point shutter slide towards the ground wire Way in, and the glide direction of ground wire shutter is vertical with the glide direction cardinal principle of L, N utmost point shutter, and back-moving spring lays respectively in ground wire shutter and L, the N utmost point shutter.

Described L, N utmost point shutter are provided with two push rods, and two push rods withstand on a side of ground wire shutter shutter; The ground wire shutter is provided with breach, after two shutters slide wherein a masthead be positioned at breach.

Described back-moving spring lays respectively in the square groove in ground wire shutter and L, the N utmost point shutter.

The utility model compared with prior art has the following advantages.

Ground wire shutter of the present utility model is vertical substantially with the glide direction of L, N utmost point shutter.Because shutter can slide towards different direction, and the stroke that slides is to utilize existing space in the socket basically, so the volume of whole socket is less, satisfies the requirement of socket volume microminiaturization fully.

Fig. 2 is the front view of the utility model safety socket;

Fig. 3 is the axonometric drawing of the utility model safety socket two shutters.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

At present, in order to strengthen the fail safe of socket, it is smaller to prevent that accident from touching the finger of conductive electrode, particularly child in the socket, in the jack of easier insertion socket.For this reason; people have designed the jack that shelters from socket as the described employing one block protection door of background technology; promptly when socket does not use; the protected door shield of jack on the socket is lived; and when socket need use; ground wire on the plug at first enter in the jack and with shutter on contact with the corresponding inclined-plane of jack position, and then promotion shutter, thus jack is opened.This device in the time of will opening jack, needs to move bigger displacement, thereby has increased the volume of socket owing to adopt a block protection door.The utility model improves at shutter, adopts structure as shown in Figure 1, and the shutter of installing in panel 1 comprises two

block protection doors

2,4, and the moving direction of the two is vertical substantially.Back-moving spring 3 one ends in the shutter 2 are positioned at the square groove in the middle of the shutter 2, on the dividing plate 11 of other end roof pressure in panel 1; Back-moving spring 5 one ends in the shutter 4 are positioned at the square groove in the middle of the shutter, and the other end is then on the side plate 12 of roof pressure in panel.Shutter 2 is provided with two push rods 21,22.Independent when stressed as L, N utmost point shutter (2), motionless because of the not stressed original position that remains on of ground wire shutter (2), this moment, two

push rods

21,22 withstood on the side of shutter 4, and shutter 4 is obstructed and can open.When people insert plug; as Fig. 2 and shown in Figure 3; because of the ground wire utmost point of plug is grown so first roof pressure moves shutter on the inclined-plane of shutter 4 a; when the breach of shutter 4 moves to the position of the push rod 21 on the shutter (2) approximately (this moment, push rod 22 correspondences the cavity of abdicating after shutter 4 moves), shutter 2 moves under the active force of L, N utmost point plug.When pulling the plug out of the socket, two

shutters

2,4 shelter from the jack of socket again under the effect of back-moving

spring

3,5.

For realizing above-mentioned action, also can make following modification to former mechanism, can reach above-mentioned purpose equally:

1., the push rod quantity on the shutter 2 can change one or several into, and can change the projection of other shape into; Or establish projection on the shutter 4, establish breach on the shutter 2.

2., shutter 4 can change two combinations into by one, two the moving direction after stressed opposite.Respectively establish one or several projection (groove) on the shutter 4.

Claims

1. safety socket; comprise panel (1); be positioned at L, N utmost point shutter and the ground wire shutter of panel (1); and be used for the spring that shutter resets; it is characterized in that: ground wire shutter (4) and L, N utmost point shutter (2) are disconnected from each other; L, N utmost point shutter (2) slide towards the ground wire Way in; the glide direction of the glide direction of ground wire shutter (4) and L, N utmost point shutter (2) is vertical substantially, and back-moving spring (3,5) lays respectively in ground wire shutter (4) and L, the N utmost point shutter (2).

2. safety socket according to claim 1 is characterized in that: described L, N utmost point shutter (2) are provided with two push rods (21,22), and two push rods (21,22) withstand on a side of ground wire shutter shutter (4); Ground wire shutter (4) is provided with breach (41), after two shutters (2,4) slide wherein a masthead (21) be positioned at breach (41).
