Abstract

A kind of power transformer, comprise housing, the coil of ribbon core, temperature control modules, power input socket, power output socket, wire is provided with in described housing, it is characterized in that: described temperature control modules is close to the outside being fixed on coil, described coil is fixed in housing by fixture, and described coil, temperature control modules, power input socket, power output socket are connected by wire.The utility model adds temperature control modules, and power transformer is protected to some extent under overload flow, in abnormal cases to electrical appliance, all can carry out auto power off connection, protection power source transformer, electrical appliance and personal security simultaneously.

Description

A kind of power transformer

Technical field

The utility model relates to a kind of power transformer.

Background technology

Along with appreciation of the RMB, the rapid development development of overseas shopping online and tourism, logistics, compatriots are numerous and confused to the U.S., Japan and other countries panic buying electrical home appliances.But, be all 100V to 120V in the voltage overwhelming majority of the electrical appliance of its this country's sale, and do not meet China's voltage standard.So, power transformer must be used normally to use.And the autocoupling type power transformer on market does not have set temperature to control or Temperature protection module usually; in the process used; power transformer or electrical appliance are under overload flow; power transformer Inside coil generates heat; when timely deenergization failed by power transformer; easy breaking out of fire, crisis life and property safety.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of power transformer.

The utility model solves the technical scheme that its technical problem adopts: a kind of power transformer, comprise housing, the coil of ribbon core, temperature control modules, power input socket, power output socket, wire is provided with in described housing, it is characterized in that: described temperature control modules is close to the outside being fixed on coil, described coil is fixed in housing by fixture, and described coil, temperature control modules, power input socket, power output socket are connected by wire.

Wherein: described wire is interconnected by Wiring connector, the end of a thread of described wire is provided with cold pressing connection terminal.

Wherein: described power input socket is arranged on the top of housing, connects temperature control modules by wire.

Wherein: in described housing, also comprise switch, described switch connects temperature control modules and coil by wire, and the button of described switch is arranged on the front of housing.

Wherein: described fixture comprises bolt, nut, pad and metal derby, described fixture is provided with ground connection ground wire, is fixed in bolt by nut and pad.

Wherein: described temperature control modules comprises self-recoverage Thermal Cutoffs, temperature controller.

The beneficial effects of the utility model are: the utility model adds temperature control modules; power transformer is protected to some extent under overload flow; in abnormal cases to electrical appliance, all auto power off connection can be carried out, protection power source transformer, electrical appliance and personal security simultaneously.

Embodiment

Referring to figs. 1 through Fig. 6, a kind of power transformer, load onto normally closed temperature control modules 12, and temperature control modules 12 is arranged on the live wire end of power input socket 13 and is connected with switch 18 by being close to outside the coil 11 of the ribbon core in housing 1.When overload or overcurrent occur for electrical appliance or power transformer, when making power transformer coil 11 temperature overflow fixed temperature, temperature control modules 12 auto power off connects, simultaneously protection power source transformer and electrical appliance.When temperature is got back to normally, temperature control modules 12 recovers to connect automatically, available protecting power transformer, electrical appliance and personal security.Meanwhile, use power input socket 13 can change the electric wire of different length, easy to use and storage.

In the utility model: wire 15 adopts Wiring connector 16 and cold pressing connection terminal 17, being connected and fixed and being interconnected wire 15, reduce processing welding, increase production efficiency.

In the utility model: the coil 11 of power transformer is provided with ground connection ground wire 25, protection electrical appliance effective grounding and electric leakage safety.

All employing the utility model equivalents or equivalent transformation and all technical schemes formed, all drop within protection range of the present utility model.
