Abstract
The utility model relates to an overload protection plug which mainly solves the problem that the safety performance of the existing plug is poor; the overload protection plug is characterized in that: two to three electrode pins (1) are electrically connected with a corresponding fixed contact (3) in a miniature circuit breaker (2) respectively, the electrode pins (1) penetrates out of the same side wall of a shell (4) of the miniature circuit breaker (2), and the electrode pins (1) are limited by the shell (4) of the miniature circuit breaker (2). The overload protection plug has the characteristics of convenient installation and usage, safety and reliability.
Description
Technical field:
The utility model relates to a kind of attaching plug, belongs to a kind of overload protection plug.
Background technology:
At present, the kind of attaching plug is a lot, except common plug, also has some to have the plug of specific function.Chinese patent CN03204261.2 discloses a kind of overload protection plug; one of them pin is connected with overload protective device; the critical piece of overload protective device is bimetal leaf and thermistor; can play the effect of current limliting and overload protection; when temperature retrieval during to normal temperature bimetal leaf and thermistor also return to normal condition, circuit is connected once more, and circuit is disconnected fully; be easy to have an accident poor safety performance if any short circuit or electric leakage.
The utility model content:
In order to overcome disadvantages of background technology; the utility model provides a kind of overload protection plug; this overload protection plug has mainly solved the problem of existing plug poor safety performance; can automatic shutdown circuit when electrical equipment has short circuit, electric leakage, overload; its function is equal to miniature circuit breaker fully, has easy to install and safe and reliable characteristics.
The technical solution of the utility model is: this overload protection plug comprises electrode pins; 2～3 electrode pins respectively with miniature circuit breaker in corresponding fixed contact electrically connect; electrode pins passes the same sidewall of the housing of miniature circuit breaker, and electrode pins is spacing by the housing of miniature circuit breaker.
Described electrode pins is 2, and miniature circuit breaker is a two plate configurations.
Described 2 electrode pins are sheet and are parallel to each other.
The end of incoming cables housings close of described miniature circuit breaker.
Each split of the housing of described miniature circuit breaker is fixed by pipe type rivet.
The utlity model has following beneficial effect: owing to take such scheme, the miniature circuit breaker volume is little, in light weight, and function admirable is reliable; the breaking capacity height is threaded off rapidly long service life; miniature circuit breaker is fixed installation in the use, is difficult to give play to the protective effect to single electrical equipment.The utility model combines miniature circuit breaker dexterously with power pin, form the overload protection plug, and is in the electrical equipment that can be applied to separately need protection, flexible.Miniature circuit breaker can automatic shutdown circuit when electrical equipment has short circuit, electric leakage, overload, and is easy to install, safe and reliable.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is profile schematic diagrames of the present utility model;
Accompanying drawing 3 is vertical views of Fig. 2.
1-electrode pins among the figure, 2-miniature circuit breaker, 3-fixed contact, 4-housing, 5-rivet.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2; this overload protection plug comprises electrode pins 1; electrode pins 1 can be made into multiple shape as required; as sheet shape, cylindrical etc.; 2～3 electrode pins 1 respectively with miniature circuit breaker 2 in corresponding fixed contact 3 electrically connect; electrode pins 1 passes the same sidewall of the housing 4 of miniature circuit breaker 2, and electrode pins 1 is spacing by the housing 4 of miniature circuit breaker 2, and housing 4 has served as the support housing of electrode pins 1.The volume of miniature circuit breaker 2 is less, mainly form by housing 4, transmission mechanism, overload protection arrangement, arc-control device, moving contact, fixed contact, binding post, transmission mechanism wherein mainly is made up of snap close, tripping, support, moving contact frame, " U " type connecting rod and handle, support, " U " type connecting rod and handle are formed four-bar mechanism, have " V " type groove on the support, one end of " U " type connecting rod places in " V " type groove and can slide therein, an end of tripping blocks mutually with snap close during normal the use, and the other end blocks " V " type groove on the support; When overheated, overload or short circuit, tripping and snap close break away from, the tripping rotation, and " V " type groove on the support is opened, and " U " type connecting rod slides along " V " type groove can't block support, and support drives moving contact and fixed contact disengaging under the effect of spring force.During use, the lead-in wire that connects electrical equipment on the outlet terminal of miniature circuit breaker 2 gets final product, and miniature circuit breaker 2 can automatic shutdown circuit when electrical equipment has short circuit, electric leakage, overload, and is easy to install, safe and reliable.
Described electrode pins 1 is 2, and 2 electrode pins 1 are sheet and are parallel to each other.Miniature circuit breaker 2 is a two plate configurations.Housing 4 is that three splits are formed, and 2 polar circuits of its inside separately use as the two-phase power supply plug.Electrode pins 1 also can be 3, and miniature circuit breaker 2 is the three-pole structure, uses as the three phase mains plug.
End of incoming cables housing 4 sealings of described miniature circuit breaker 2, input terminal is substituted by electrode pins 1.
By shown in Figure 3, each split of the housing 4 of described miniature circuit breaker 2 is fixing by pipe type rivet 5, and housing 4 can not become flexible, and avoids the accident of meeting accident.
Claims (5)
