To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：

According to a specific embodiment of the present utility model, there is provided a kind of safety patch board assembly, it is by complementary plug Constituted with insert row body, the complementary plug can be nested on electrical appliance plug, it is by lamellar body and is arranged on the lamellar body Dielectric cylinder composition；The insert row body is provided with one or more groups of jacks, and conducting strip is provided with the jack；It is each The position for corresponding to the dielectric cylinder between the group jack is provided with a circular hole, and spacing machinery is provided with the circular hole Switch.

Safety patch board assembly according to an embodiment of the invention, wherein, when being inserted without plug, the spacing machinery Switch is arranged at the conducting strip in the jack in original position, its disconnection, and now no current passes through in the jack.

Safety patch board assembly according to an embodiment of the invention, wherein, the dielectric cylinder is arranged at described The middle position of body, correspondingly, the circular hole for accommodating the spacing mechanical switch is arranged at the centre of jack described in a group At position.

Safety patch board assembly according to an embodiment of the invention, wherein, when the complementary plug is nested into electrical appliance On plug, when then in the electrical appliance plug insertion jack, the dielectric cylinder is contained in the circular hole and institute State spacing mechanical switch to be depressed, cause the spacing mechanical switch to decline, connect the conducting strip, so as to zero line and fire Line forms current path.

Safety patch board assembly according to an embodiment of the invention, wherein, the front end of the dielectric cylinder is set to Contact shape.

Safety patch board assembly according to an embodiment of the invention, wherein, the front end of the spacing mechanical switch is set There is auxiliary piece, increase contact area, it is ensured that contact effectively contacts with spacing mechanical switch when in use, connection circuit.

Complementary plug is only nested into electrical appliance plug and inserts the electrical appliance by safety patch board assembly of the present utility model Circuit just can turn on during head insertion jack, and in the case of not use, the spacing mechanical switch is in original position, in disconnection jack Conducting strip, even if therefore have children will electric conductor insert jack in there will not be electric current and pass through.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain this Utility model, is not used to limit the utility model.

As shown in Figures 1 to 3, safety patch board assembly of the present utility model is by insert row body (being not entirely shown) and complementary plug 2 compositions.

As shown in Fig. 2 complementary plug 2 is made up of lamellar body 8 and the dielectric cylinder 7 being arranged on lamellar body 8.

In a preferred embodiment, the top of the dielectric cylinder 7 is set to contact shape.

In a preferred embodiment, the dielectric cylinder 7 is arranged on the centre position of lamellar body 8.

In a preferred embodiment, the front end of spacing mechanical switch 5 is provided with an auxiliary piece, thus increases and touches Point and the contact area of spacing mechanical switch 5, it is ensured that when deployed, spacing mechanical switch 5 is pressed so that zero line, live wire and Conducting strip 4 is connected with 6, thus connection circuit.

The insert row body of safety patch board assembly of the present utility model is provided with one or more groups of jacks, is set between every group of jack A circular hole is equipped with, the diameter of the circular hole is arranged to allow dielectric cylinder 7 just to enter；The position of the circular hole is, as general Complementary plug 2 is nested on electrical appliance plug 1 and the electrical appliance plug 1 is further inserted into insert row body, i.e. metallic conduction post 3 During into jack, dielectric cylinder 7 is inserted into the circular hole simultaneously.A spacing mechanical switch is provided with the circular hole 5, when complementary plug 2 is not inserted into, it is located at original position, and zero line, live wire and conducting strip are disconnected, and forms open circuit.Now, even if youngster It is virgin that electric conductor to be inserted and there will not be electric current in jack and pass through accidentally.
