Description

A kind of electric shock-prevention safety plug

Technical field

The utility model relates to a kind of electric shock-prevention safety plug.

Background technology

Plug is mounted in and is used for a kind of electrical connection of being electrically connected with supply socket on electrical appliance or the power socket.Traditional plug generally comprises the contact that is installed on the housing, contact has with housing and is fixedly installed togather, and also has relative to housing to rotate, the quantity of contact has two, also has three.During use, only with hand is held housing, and contact is aimed at the socket of supply socket, firmly contact is pushed in the receptacle sockets to get final product, and is very simple.The plug of traditional structure, simple in structure, with low cost, easy to use, use very extensively, weak point is, the contact part of traditional structure plug all is directly exposed to outside, and contact is charged in the process of inserting supply socket, and hold with a firm grip the position of housing of staff is nearer apart from contact, therefore has the danger of getting an electric shock in the process of inserting plug, especially for children, it inserts posture easier causing lack of standardization and gets an electric shock, and safety in utilization is relatively poor.

Summary of the invention

The utility model content

The technical problems to be solved in the utility model be at above-mentioned deficiency provide a kind of rational in infrastructure, be difficult for to get an electric shock, safe electric shock-prevention safety plug.

For solving the problems of the technologies described above, this electric shock-prevention safety plug comprises the contact that is installed on the housing, its design feature is: described housing is the tubular of opening towards the contact outer end, be provided with the insulating case that is sleeved on the contact in the housing, insulating case the inner and housing the inner are provided with and drive the spring that insulating case slides along contact.

The electric shock-prevention safety plug of this structure realizes being difficult for electric shock, safe by the elastic reset isolation structure.

The elastic reset isolation structure mainly comprises the insulating case that is sleeved on the contact outside, and insulating case can slide along the lengths of contacts direction; Housing is arranged to the tubular of opening towards the contact outer end, and when the relative contact of insulating case slided, the insulating case outer wall is inner walls slip relatively also; Be provided with spring between insulating case and the housing adjacent face, under nature, spring ejects insulating case in housing along the lengths of contacts direction, and at this moment, insulating case is wrapped in the contact outside, has only the outer end of contact to expose insulating case.During use, hold housing, the supply socket jack is aimed in the contact outer end, at this moment, the outer face of insulating case also is adjacent on the supply socket end face, when the application of force is pushed housing to supply socket, insulating case will move in housing along the lengths of contacts direction, spring is compressed, and like this, contact is just visited from insulating case and exposed in the jack that inserts supply socket.Insert in the process of receptacle sockets at contact, the contact of receptacle sockets outside is insulated the cover parcel always, and therefore, insulating case is kept apart staff and contact, has effectively avoided the generation of electric shock accidents, has improved safety in utilization.

As improvement, the contact outer end is provided with embedded hole.

Embedded hole is set on contact, can makes contact when inserting supply socket, the metal clips in the socket can be clamped in the embedded hole both sides of contact, not only helps contact and is electrically connected well with the socket metal clips, and it is more stable also to help plug to be inserted on the socket.

As further improvement, inner walls is provided with the chute that be arranged in parallel with contact, and insulating case outer wall the inner is provided with the slide block that probes in the chute.

Chute is set on inner walls, and on the insulating case outer wall, is arranged at the slide block that chute is slidingly matched, can the slip of insulating case be play the guiding role, more smooth and easy when insulating case is slided.

As further improving, the chute outer end is provided with block.

In the chute outer end block is set, can prevents effectively that insulating case from skidding off in housing the position-limiting action that slided of insulating case.

In sum, adopt the electric shock-prevention safety plug of this structure, rational in infrastructure, be difficult for to get an electric shock, safe, be adapted at various electricity consumption occasions and use, be particluarly suitable for using in old man or child's the family, can effectively prevent to get an electric shock, help to improve the electricity consumption reliability.

Description of drawings

In conjunction with the accompanying drawings the utility model is described in further details:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1 user mode;

Fig. 3 is the A-A cutaway view of Fig. 1 nature.

Among the figure: 1 is housing, and 2 is contact, and 3 is insulating case, and 4 is spring, and 5 is embedded hole, and 6 is chute, and 7 is slide block, and 8 is block, and 9 is nut, and 10 is slide opening.

Embodiment

As shown in Figure 1, this electric shock-prevention safety plug comprises housing 1, and it is square tubular that housing 1 is opening.As shown in Figure 2, the contact 2 that two parallel interval are provided with is installed in the housing 1, contact 2 the inners are connected with housing 1 internal fixation, and contact 2 outer ends lean out from housing 1 oral area, and in the present embodiment, contact 2 the inners are fixedly mounted in the housing 1 by nut 9.Be fitted with the insulating case 3 that slides to opening direction along housing 1 inwall in the housing 1, insulating case 3 is the tubular of opening towards housing 1 inner bottom surface, housing 1 inwall is provided with the chute 6 that is provided with along contact 2 length directions, be installed with the slide block 7 that probes in the chute 6 on insulating case 3 outer walls, like this, when insulating case 3 slides, slide block 7 will slide in chute 6, played guide effect, slided more smooth and easy.Chute 6 outer ends are provided with block 8, when slide block 7 when chute 6 outwards slides, can prevent that limited slip block 7 skids off, and has played position-limiting action.Insulating case 3 bottom surfaces are provided with the slide opening 10 corresponding with contact 2 positions, and contact 2 passes in slide opening 10.Be provided with spring 4 between insulating case 3 inner bottom surfaces and housing 1 inner bottom surface, the effect of spring 4 is that insulating case 3 is outwards ejected along contact 2.As shown in Figure 3, under the nature, insulating case 3 is spacing by block 8, and at this moment, contact 2 has only the outer end sub-fraction to expose insulating case 3, has played the effect of isolating staff and contact 2, can effectively avoid electric shock accidents to take place.As shown in Figure 2, contact 2 outer end portion are provided with embedded hole 5, the main effect of embedded hole 5 is when this electric shock-prevention safety plug inserts in the jack of supply socket, the metal clips of supply socket can screens in the left and right sides of embedded hole 5, it is more reliable that the metal clips of contact 2 and supply socket is seated, and can avoid effectively that contact 2 ejects in supply socket under the elastic force effect of spring 4.
