the terms "first" "second""third" as used herein denoted for description only, and
should not be interpreted as an indication or implication of relative importance.
[0023] It should be noted that, in the description disclosed herein, except otherwise specified
and defined, the terms "installation", "connected"and "connection" should be interpreted
in a broad sense, for example, it can be fixed connection, detachable connection or
integrated connection; it can be mechanical connection or electrical connection; it
can be directly connected, or indirectly connected through inter medium, and it can
be the connection between two components. For one of ordinary skill in the art, the
specific meaning of the above terms in the invention can be understood according to
the specific situation.
[0024] As shown in FIGS. 1-9, a socket 1 comprises the socket body 11, wherein the socket
body is provided with at least one plug position, whereas in this embodiment, the
socket body is provided with two plug positions, and the socket body with multiple
plug positions can also be produced according to the actual demand.
[0025] Specifically in this embodiment, the socket body 11 is provided with a first positioning
slot 12 and two 13, wherein the plug 2 can be inserted into the first and/or second
positioning slot, therefore the socket has two insertion positions.
[0026] The shape of the plug is confirmed to that of the first positioning slot and second
positioning slot.
[0027] Three power contacts are respectively set in the first positioning slot and second
positioning slot for conforming to the plug, wherein the power contacts are earth
line contact, live line contact and neutral line contact, respectively, and wherein
the two sides of the earth line contact are respectively set with live line contact
and neutral line contact, and the height of the earth line contact is higher than
the live line contact and neutral line contact. In this case, the contact design is
adopted instead of the jack design, leaving the upper side of the socket a closed
surface, which has a very good waterproof effect, and also avoids electric shock accidents
caused by children inserting metal into the jack. In this case, the earth line is
used to separate the live line from the neutral line., therefore, in case of electric
shock, the earth line can also be used to conduct electricity to avoid safety accidents.
[0028] Furthermore, the three power contacts are lower than the height of the first and
second positioning slots, which is in sinking style. The insulating ring 18 is arranged
around the power contact as the contact protection. If the power contact is flat,
or even higher than the socket body, children are prone to danger by holding a magnet
to absorb the contact.
[0029] Refinement of implementation plan, wherein, the depth of the first and second positioning
slots is between 1mm-10mm, preferably 2-5mm.
[0030] Specifically in this embodiment, the middle of the first positioning slot 12 is provided
with a first earth line contact 122, and wherein both sides of the first earth line
contact are respectively provided with the first live line contact 121 and the first
neutral line contact 123. It should be noted that the depth of the first earth line
contact is lower than that of the first live line contact and the first neutral line
contact. For example, when the depth of first earth line contact is 1mm, the depth
of the first live line contact and the first neutral line contact can be 2mm-5mm.
Similarly, the middle of the second positioning slot is provided with a second earth
line contact 132, and wherein both sides of the second earth line contact are respectively
provided with the second live line contact 131 and the second neutral line contact
133.
[0031] The socket body is internally provided with at least two fixed blocks, i.e., the
first fixed block 141 and the second fixed block 143. The first fixed block and the
second fixed block are both connected with the metal elastic sheet. Wherein, the two
metal elastic sheets correspond to the live line contact and neutral line contact,
respectively. When the plug is inserted into the first or second positioning slot,
the metal spring will be connected to the live line contact and the neutral line contact
through magnetizing by the magnet in the plug and the circuit is on thereby.
[0032] Specifically in this embodiment, see FIG. 2, the socket body is internally provided
with the first fixed block 141 and the second fixed block 143, wherein, the first
fixed block is connected with a first metal spring 151. In coordination with it, one
side of the first live line contact 121 is connected with a first metal connecting
plate 161, and one side of the second live line contact 131 is connected with a second
metal connecting plate 163, and wherein both ends of the first metal spring are directly
above the first metal connecting plate and the second metal connecting plate. The
second fixed block is connected with a second metal spring plate 153. In coordination
with it, a third metal connecting plate 162 is connected at one side of the first
neutral line contact 123, and a fourth metal connecting plate 164 is connected at
one side of the second neutral line contact 133, wherein both ends of the second metal
spring plate are directly above the third metal connecting plate and the fourth metal
connecting plate. The first earth line contact 122 and the second earth line contact
are connected through the third metal connecting plate 152. The live line 171 of the
power supply is connected with the first fixed block 141 through the wire, the neutral
line 173 of the power supply is connected with the second fixed block through the
wire, and the earth line 172 of the power supply can be connected with the third metal
connecting plate through the wire.
[0033] The first metal connecting plate, the second metal connecting plate, the third metal
connecting plate and the fourth metal connecting plate are set up, instead of connecting
the metal spring contact directly with the power contact (live line contact and neutral
line contact). The purpose is to prevent children from safety accidents caused by
accidental adsorption of metal elastic sheet caused by sticking magnets to live line
contact and neutral line contact, therefore, in this case, single point adsorption
is adopted, wherein the probability of simultaneously triggering the live line and
neutral line is small, but it cannot be ignored.
[0034] Furthermore, the third metal connecting plate contacts the socket body through the
central fixed block 142.
[0035] Specifically in this embodiment, the first metal connecting plate is same in construction
with the second metal connecting plate, see FIG. 4. Wherein, the first metal connecting
plate 151 comprises a horizontal clamping plate 1511, of which both sides are respectively
provided with a left chute board 1512 and a right chute board 1514, and wherein the
left chute board is connected with the left horizontal clamping plate 1513, which
is set directly above the first live line contact; the right chute board is connected
with the right horizontal clamping plate 1515, which is set directly above the second
live line contact.
[0036] Refinement of implementation plan, wherein the left chute board and right chute board
are provided with regulation orifices 19, in which a jack bolt 192 is installed, wherein
the jack bolt is in threaded connection with the screw holes 191 inside the socket
body, thereby adjusting the relative height of the left horizontal clamping plate
and the right horizontal clamping plate to the power contact.
[0037] The disclosure provides a plug 2 conformed to the socket, as shown in FIGS 5 to 9.
Wherein, the plug comprises a plug body 21, which is hollow inside, a strong magnetic
plate 26 is installed on the plug body, and wherein, a first sliding hole 271, a second
hole 272 and a third sliding hole 273 are set on the strong magnetic plate. Wherein,
the sliding fit in the first sliding hole is matched with the live line matching column
22; the second hole is fixed with the earth line matching column 23; the sliding fit
in the third sliding hole is matched with the neutral line matching column 24, and
wherein a first fixed column 274 and a second fixed column 276 are arranged in the
plug body, among which the first fixed column is connected with the live line matching
column through the left metal elastic plate 275, and the second fixed column is connected
with the neutral line matching column through the right metal elastic plate 277. The
first fixed column is connected with the first wire 281, the second fixed column is
connected with the second wire 283, and the earth line matching column is connected
with the third wire 282. The first wire, the second wire and the third wire can be
connected with the power cord of the electrical appliance by passing through the perforation
25 on one side of plug.
[0038] Furthermore, the length of the earth line matching column protruding from the metal
elastic sheet is less than the length of the neutral line matching column and the
live line matching column.
[0039] Furthermore, the length of the neutral line matching column and live line matching
column protruding from the metal elastic sheet is greater than that of the first live
line contact and first neutral line contact. Since the power contact of the socket
is fixed, the elastic movement of neutral line matching column and live line matching
column can lead to better conjunction of the plug with the socket under the action
of strong magnetism.
[0040] Furthermore, a spacing adjustor is arranged between the strong magnetic plate and
the plug body, see FIGS. 8-9. Wherein, the spacing adjustor comprises a cannula 291,
and wherein the cannula is provided with a jack 295, and the inner wall of the jack
is provided with several ring grooves 292, in coordination with it, the plug body
is provided with an inserting rod 293, wherein its end is provided with a ring chuck
294, which is matched with the ring groove. The relative distance between the strong
magnetic plate and the socket can be changed by pressing the strong magnetic plate
to place the ring chuck in different ring grooves, thereby changing the absorbed magnetic
force.
[0041] Working mode: Suppose the plug is inserted into the first positioning slot 12 of
the socket, meanwhile, the strong magnetic plate is adsorbed in the first positioning
slot. At this time, while the earth line matching column is inserted into the first
earth line contact, the neutral line matching column and live line matching column
are in good contact with the first neutral line contact and the first live line contact
under the action of the metal elastic plate. Due to the existence of strong magnetic
plate, the end of the first metal connecting plate and the second metal connecting
plate can be adsorbed to contact with the first neutral line contact and first live
line contact, respectively, and the circuit is on thereby.
[0042] FIG. 10 is the structure diagram of the power strip provided by the embodiment of
