Abstract

The utility model relates to a plug and a socket with security protection. The utility model is used for connecting an electric appliance and an alternating current power. A pin of the plug is curved into a shape which is a triangle formed by three points. A plurality of groups of fan-shaped holes are arranged on a panel of the socket. When the pins are completely inserted into the socket, the two pins are positioned at the inner sides of two copper sheets. The two pins are not communicated with a power. The accident of electric shock, which is caused because an operator touches the pins by accident, can be avoided. When the plug is rotated to form a certain angle, the pins are communicated with the power. The plug can not be directly extracted when the plug is positioned at a connecting position. Simultaneously, the plug is locked by a locking sheet when the plug is positioned at a rotating position. Therefore, the plug and the socket have the advantages of reliable connection and safe operation. The plug and the socket are specially suitable for being used by families with children.

Description

Safety plug and plug seat for family

The utility model is a kind of plug that has safeguard protection and socket that is used for electrical equipment and AC power connection.

The existing plug that is used for electrical equipment and AC power connection is made up of insulator, pin latch; Socket (can insert the multi-gang socket of 3-5 plug) is made up of seat shell, panel, copper sheet, spring.Above-mentioned plug and socket all adopt direct insertion connecting mode.Though use more conveniently, also have following defective: when the multi-gang socket partial spring lost efficacy, easily cause loose contact or cause plug to come off; When plug was in half insertion with power connection, the latch that is exposed to the outside was easy to cause the operation electric shock accidents; When plug separated with socket, children easily imitated the hand-held conductive body of adult or plug and are inserted into and cause electric shock accidents in the hole.

The utility model is exactly to make improvements and a kind of household safe protection plug and the socket that propose at these defectives.

The utility model the latch of original plug is curved "

" shape, making many groups garden shape of original socket panel or rectangular through holes into many group scallop holes, dough model casts out spacing reinforcement boss after the scallop hole, only is equipped with on panel at sector-shaped aperture locking plate slidably upwards.Two copper sheets in the seat shell are arranged in the outside on scallop hole perspective plane, plug inserts the seat hole, latch is positioned at the copper sheet inboard, thereby do not have a contact condition of original plug, when plug after angle of scallop hole rotation, the latch terminal surface is just and the copper sheet connection, in the rotation connection process, the gap on pin insulator bottom surface and socket panel surface is to determine by the fit dimension of latch and panel positive stop lug boss, and plug outwards moves the restriction that is subjected to boss, has reached the purpose of safety operation.During coupled situation, if there is not reverse rotation, plug the disconnecting phenomenon that comes off can not occur.For making connection more reliable, can move on to the appropriate location to slide lock tabs, so just can lock plug.

The utility model increases part hardly and cost has obtained following effect:

1. with the power supply connection process with after power supply connects, latch does not expose, handling safety.

2. connect reliable.

3. during breakaway plug,, significantly reduce the danger of children with the thin bar touching of conduction electrode because panel and positive stop lug boss protecting cover copper sheet.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the section of structure of the utility model in coupled situation.

Fig. 2 is a multi-gang socket vertical view of the present utility model.

2. 1. household safe protection plug be made up of with the improvement latch insulator.Household safe protection socket by the seat shell 8., panel 7., copper sheet 5., 6. spring form.During joining power, to 2. insert with the latch that 1. insulator is connected from one group of scallop hole (11) initiating terminal that 7. socket panel is gone up, treat insulator 1. bottom surface and panel after 7. the surface contacts, again plug is forwarded to scallop hole (11) terminal point in the direction of the clock, this with process that power supply connects in, the plane that 2. latch is gone up 3. import earlier panel 7. the back side mould the casting boss 9., 5. 4. the plane that 2. the position latch of reaching home is gone up contact and joining power with copper sheet.Stablize for guaranteeing to connect in the certain hour, 7. panel can be gone up the appropriate location that radially slide into locking plug of the locking plate (10) of installation along scallop hole (11), the revolution of restriction plug.In case plug is subjected to a masterpiece time spent of outwards dialling, 9. the panel 7. boss at the back side withstands on latch plane 2. and 3. goes up, and the restriction plug outwards moves.When needing outage, first slippage locking plate (10) by the initiating terminal that counterclockwise is turned back to scallop hole (11), can be transferred to plug to latch.

Claims

1, one by insulator 1., latch 2., panel 7., copper sheet 5., spring 6., the seat shell 8., plug and the socket formed, it is characterized in that latch 2. have one with boss 9. to the top the plane 3. with one with the 5. joining plane of copper sheet 4., the positive stop lug boss that panel has one or more groups the symmetrical scallop hole (11) and the back side to mould on 7. to cast out 9., the locking plate (10) that is installed in that 7. panel is gone up and can radially slides along scallop hole (11).

2, plug according to claim 1 and socket is characterized in that the initiating terminal of scallop hole (11) is wideer than terminal.
