Abstract
The utility model discloses a ceramic isolation type socket for double line power off detachable switch. The structure of the ceramic isolation type socket comprises an outer shell (1), a detachable switch (2), a copper sheet (3), a movable ceramic bar (4), a spring (5) and a spring support plate (6), wherein the detachable switch (2) (the master switch of the socket) is detachable and is positioned at the tail end (in the reverse direction of a wire inlet end of a normal socket) of the socket, and two switches are arranged in the detachable switch (2) and are respectively connected with a live wire and a zero wire of the mains supply; when the switch is closed, the live wire and the zero wire can be completely cut off, the movable ceramic bar (4) and the spring (5) in the socket are used in a matched manner, the copper sheet (3) in a plug hole is isolated from the plastic outer shell of the socket, the outer shell of the socket can be prevented from being burned, and good contact between the socket and the plug head is realized. According to the ceramic isolation type socket, the service life of the socket is prolonged, safety of power utilization is strengthened, reliable performance is achieved, and ease of production and wide prospect are realized.
Description
Technical field
The utility model relates to a kind of safety socket, relates to specifically a kind of isolated socket of pottery of two-wire power-off detachable switch.
Background technology
At present, known socket switch is all positioned near of socket end of incoming cables, in the time that the plug inserting is more, closes and opens socket switch and just seem convenient not.
Currently marketed all sockets have just disconnected single line (live wire or zero line) in fact closing after the switch that socket itself carries, that is to say and really all do not cut off the electricity supply, the machine parts being connected with socket still can be in electriferous state, now, false touch touches and in jack, still there will be shock hazard.
At present, the useful life of known socket is all shorter, and subject matter shows loosening loose contact and the excessive shell that burns of load of causing of copper sheet.
Summary of the invention
The purpose of this utility model is to have overcome the deficiencies in the prior art, and a kind of isolated socket of pottery of two-wire power-off detachable switch is provided.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
1, its structure comprises shell (1), detachable switch (2), copper sheet (3), movable ceramic bar (4), spring (5), spring-support plate (6) composition, it is characterized in that: built-in two switches of described detachable switch (2), be connected with zero line with the live wire of civil power respectively, when this switch is during in closed condition, can thoroughly cut off live wire and zero line.
2, described detachable switch (2) (being the master switch of socket) is detachable, is fixed on shell (1) upper with screw, and it is convenient to change.
3, described detachable switch (2) is positioned at the end (being the opposite direction of common socket end of incoming cables) of socket, has improved the convenience that uses switch.
4, socket inside is used in conjunction with movable ceramic bar (4) and spring (5), plastic casing isolation by copper sheet in jack (3) with socket, in order to avoid copper sheet burns jack housing because of heating in the excessive jack of load, make the contact of socket and plug more good simultaneously.
Compared with prior art, the beneficial effects of the utility model are:
Close after socket switch, live wire and zero line can thoroughly cut off, and prevent that the charged and child of machine from touching; Socket master switch is arranged to modular detachable, and it is convenient to change; Socket master switch is positioned at the opposite direction of end of incoming cables, has improved the convenience that uses switch; Socket inside is used in conjunction with movable ceramic bar and spring, by the plastic casing isolation of copper sheet in jack and socket, in order to avoid copper sheet burns jack housing because of heating in the excessive jack of load, makes the contact of socket and plug more good simultaneously.The present invention has extended the useful life of socket, has strengthened Electrical Safety, and dependable performance is easily produced, and has a extensive future.
Brief description of the drawings
Fig. 1 is the vertical section structural map of first embodiment of the utility model.
Fig. 2 is the vertical section structural map of second embodiment of the utility model.
1. shells in figure, 2. detachable switch, 3. copper sheet, 4. movable ceramic bar, 5. spring, 6. spring-support plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
The isolated socket of pottery of a kind of two-wire power-off detachable switch shown in Fig. 1, is made up of shell 1, detachable switch 2, copper sheet 3, movable ceramic bar 4, spring 5, spring-support plate 6.Built-in two switches of detachable switch 2, are connected with zero line with the live wire of civil power respectively, when this switch is during in closed condition, can thoroughly cut off live wire and zero line, make the copper sheet in socket no longer charged; Detachable switch 2(is the master switch of socket) because frequency of utilization is high, can damage because of inside sparking, thereby be designed to dismountable modular, be fixed on shell 1 with screw, in the time damaging, be convenient to timely replacing; Detachable switch 2(is the master switch of socket) be positioned at the end (being the opposite direction of common socket end of incoming cables) of socket, like this, in the time that the plug inserting on socket is more, be also easy to control smoothly the closure of socket power; The effect one of movable ceramic bar 4 is heat insulation, prevents from burning shell, the 2nd, and under the pressure of spring, make the contact between copper sheet more tight, prolong socket useful life; Spring-support plate 6 is fixedly connected with shell 1 is vertical, plays the effect of fixing spring 5.
In embodiment illustrated in fig. 2, change the direction of insertion of plug in Fig. 1, increase the quantity inserted of three hole plugs, make the plug of three hole plugs convenient rationally simultaneously.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
