In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a switch of area threshold, includes casing and panel, can dismantle the connection through the buckle between casing and the panel, be equipped with a plurality of jacks on the casing, the inside of casing is equipped with the relay circuit who is used for the control switch action, there is movable separation blade jack inside, and when the jack did not insert the plug, the jack was sheltered from to the movable separation blade, and when the plug inserted the jack, the inward bending of movable separation blade to contact with relay circuit.

As a further technical solution of the present invention: the jack has 5, constitutes a two hole sockets and a three hole sockets respectively.

As a further technical solution of the present invention: the shell is made of PC materials.

As a further technical scheme of the utility model, the relay circuit includes relay K, switch S1, switch S2, switch S3, switch S4 and switch S5, switch S1, switch S2 and switch S3 are connected in series in proper order after one end is connected with the power VCC, the other end is connected with relay K, switch S4 and switch S5 are connected in series after one end is connected with the power VCC, the other end is connected with relay K, relay K ' S other end ground connection, load L is connected to relay K ' S contact K-1 one end, relay K ' S contact K-1 other end ground connection, the other end of load L is connected the power VCC.

As a further technical solution of the present invention: the relay K is a normally open contact relay.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses take threshold switch not external power supply when not connecing the load, not external power supply when inserting the load insecure, only when inserting standard socket, this switch just can normally supply power to the outside to very big increase the security, reduce electric shock and electric leakage probability.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, example 1: the utility model provides a switch of area threshold, includes casing 1, be equipped with a plurality of jacks 2 on casing 1, use figure 1 as an example, jack 2 has 5, can constitute 1 three hole sockets and 1 two hole sockets, the inside of casing 1 is equipped with the relay circuit who is used for the control switch action, each 2 inside movable separation blade 3 that all have of jack, movable separation blade 3 is electrically conductive material, when jack 2 does not insert the plug, movable separation blade 3 shelters from jack 2, when the plug inserts jack 2, 3 incurvation of movable separation blade, and contact with the relay circuit. When the plug is not inserted into the jack 2, the plug is not provided with a power supply, electric leakage caused when substances with conductive properties are prevented from being inserted into the jack 2, when the plug is plugged into the power supply, the movable blocking pieces 3 are bent inwards under the pressure action of the plug, at the moment, the movable blocking pieces 3 play a role of a switch, an internal relay switch is opened, normal power supply is started, the two jacks 2 forming the two-jack socket in the upper part in the drawing are taken as examples, when only one jack 2 on one side is inserted, the condition of opening the relay is not provided, the power can not be switched on, the movable blocking pieces 3 in the 5 jacks 2 are independently powered on, the cooperation is realized, each jack 2 can independently detect current, when only one side passes through the current, the current detection can also be realized, and the circuit protection function is realized.

The relay circuit is shown in fig. 3, switches S1-S3 in the figure correspond to a three-hole socket, switches S4-S5 correspond to a two-hole socket, and only when a qualified plug is inserted, the corresponding movable blocking piece 3 is bent inwards under the pressure action of the plug, so that the switches S1-S3 or S4-S5 are closed, the relay K can be powered on, the contact K-1 is closed, and the loop of the load L is conducted.

Example 2: on the basis of embodiment 1, the housing 1 of the present design is made of PC material. The housing 1 is excellent in corrosion resistance and insulation, and is composed of a panel and a bottom case. The panel is connected with the bottom shell in a separable way, so that the use and later-stage circuit troubleshooting and maintenance are very convenient.
