Abstract
The utility model relates to a socket capable of preventing short circuits, which comprises a socket body, a short circuit indication lamp and 3-5 groups of insertion holes, wherein the short circuit indication lamp is arranged on the upper surface of the insulated socket body, positive-negative paired pole pieces J are respectively arranged in each group of insertion hole, the positive electrode of the pole piece J is connected with the positive electrode of an external power supply E, the negative electrode of the pole piece J is connected in series with an electromagnet X with a loop, a single-pole double-throw switch K is arranged above the electromagnet X, one end of the short circuit indication lamp is connected with the negative electrode of the external power supply E, the other end of the short circuit indication lamp is provided with a metal contact (2), a metal contact (1) is led out from the negative electrode of the external power supply E by a lead, and the single-pole double throw switch K can be respectively in electric contact with the contact (1) and the contact (2). When the electric equipment is overloaded or short-circuited, the socket can quickly switch off the power supply, so that the electric appliance and personal safety are effectively guaranteed and the safety performance is high.
Description
Technical field
the utility model relates to a kind of supply socket, especially the high anti-short circuit socket of security performance.
Background technology
are present, and known socket does not have protective device when power consumption equipment overload or short circuit, cause electrical equipment to burn damage easily, possibly cause the personal safety accident when serious, and security performance is not high, brings inconvenience to daily life.
The utility model content
do not have the problem of short-circuit protection, the utility model that a kind of anti-short circuit socket is provided in order to overcome existing socket, when power consumption equipment overload or short circuit, can cut off the electricity supply rapidly, ensure electrical equipment and personal safety effectively, and security performance is high.
the utility model solves the technical scheme that its technical problem adopted: this anti-short circuit socket comprises socket, short circuit indicator light and 3-5 group jack; Socket upper surface in insulation is provided with the short circuit indicator light; Be respectively equipped with positive and negative paired pole piece J in every group of jack; The positive pole of pole piece J links to each other with the positive pole of external power supply E, and the electromagnet X of the negative pole of pole piece J and belt coil is connected in series, and electromagnet X top is provided with single-pole double-throw switch (SPDT) K; Short circuit indicator light one end connects external power supply E negative pole; 2. the short circuit indicator light other end is provided with hard contact, and 1. external power supply E negative pole draws hard contact through lead, and 2. 1. single-pole double-throw switch (SPDT) K can electrically contact with the contact with the contact respectively.During operate as normal, thereby 1. single-pole double-throw switch (SPDT) K and contact are connected and are the power consumption equipment power supply; When pole piece J overload or short circuit; The electric current that flows through in the coil of electromagnet X increases rapidly; The electromagnetic attraction that produces makes single-pole double-throw switch (SPDT) K 1. switch to the contact 2. from the contact, lights the short circuit indicator light simultaneously thereby cut off external power supply E, reaches the purpose of short-circuit protection.
The beneficial effect of
the utility model is: when power consumption equipment overload or short circuit, can cut off the electricity supply rapidly, ensure electrical equipment and personal safety effectively, security performance is high.
