Abstract
The utility model relates to a socket with a short circuit switch. The utility model is characterized in that an electromagnetic system trip is arranged in a socket shell, and a drive coil of the trip is connected in series between a tripping switch and an output terminal. When a short circuit or an overload occurs, the trip can quickly cut off a power supply, so that safety protection can be realized. The utility model has the advantages of safety, convenient operation, etc.
Description
The utility model relates to a kind of electrical installation, and is especially a kind of with the socket of electromagnetic principle to rapidly automatic powered-down under the short-circuit conditions.
Existing supply socket no matter be the socket that industrial electrical equipment, office appliance or household electrical appliance use, generally adopts the terne metal fuse as short-circuit protection, and this short-circuit protection mode cost is low, uses comparatively general.Its shortcoming is to change fuse and comparatively bother; And some lack the user of electricity consumption knowledge, random overstriking fuse or use blister copper silk, and feasible " fuse " non insurance, even lead to electrification and cause electrical fire, this is very dangerous.
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of and need not to change fuse, and when electrical equipment is short-circuited or transship, can be rapidly powered-down automatically, the supply socket that after fault is got rid of, can conveniently connect.
For achieving the above object, the utility model adopts following technical scheme: be provided with the release that is similar to earth leakage circuit-breaker in socket.The drive coil of this release is serially connected between the dropout switch and lead-out terminal of release.Load on being connected to output plughole is short-circuited or when transshipping, the voltage at the drive coil two ends of release raises rapidly, and electric current increases rapidly, and the electromagnetic force of its generation disconnects the dropout switch rapidly, realizes timely defencive function.
Provide embodiment below in conjunction with accompanying drawing.
Fig. 1 is a circuit diagram of the present utility model;
Fig. 2 is the structural representation of release of the present utility model.
The utility model comprises that socket shell, socket shell are provided with jack, be provided with lead-out terminal (10) in the jack, its innovation part is: be provided with release (20) in the socket shell, the drive coil (21) of this release (20) is serially connected between the dropout switch (22) and the lead-out terminal (10) in the jack of release (20).
Get rid of the back energized for the ease of fault, the reset button (23) or the release link of release (20) are exposed to outside the socket shell.
In addition, also be provided with power supply indicator (30), with the indication normal condition in socket shell front plate.
Output plughole of the present utility model can be two slotting, three slotting or its combinations, and panel can be standard type or designs by particular requirement.
The utility model has the advantage of: 1. safe and reliable, took place 0.1 second in short circuit or overload Interiorly can cut off the electricity supply rapidly to protect lives and properties; 2. easy to use, need not to change fuse.
Claims (3)
1. electromagnetic short circuit protection combined socket and switch; comprise that socket shell, socket shell are provided with jack; be provided with lead-out terminal (10) in the jack; it is characterized in that: be provided with release (20) in the socket shell, the drive coil (21) of release (20) is serially connected between the dropout switch (22) and the lead-out terminal (10) in the jack of release (20).
2. electromagnetic short circuit protection combined socket and switch as claimed in claim 1 is characterized in that the reset button (23) or the release link of release (20) is exposed to outside the socket shell.
3. electromagnetic short circuit protection combined socket and switch as claimed in claim 1 is characterized in that socket shell (10) front plate also is provided with power supply indicator (30).
