Description

Plug structure with overload protection

This creation is about a plug structure with overload protection, especially a modular structure design, which can not only increase the production efficiency, but also use automated operations for wire crimping and bonding, which can relatively reduce the production cost. And make the overall volume smaller, more convenient to use, and in the overall implementation and use of the plug structure innovation designer with overload protection with more practical features.

According to the press, the use of electricity is inseparable from the life of modern people. There are all kinds of electrical equipment around people's daily life, which can bring great convenience to people's life, and the energy source required to drive all kinds of electrical equipment That is to say, the power company uses cables to transmit and supply the electric energy to various places, and generally, in order to make it convenient for people to obtain electric energy for use, the electric energy is connected to the socket, and then various electrical appliances are connected to the mains socket through the electric wire using the power plug. Set up links to provide electrical appliances with electrical power transmitted by wires.

Generally, wires, plugs, sockets, etc. all have their rated voltage and current capacity. When the transmitted voltage and current exceed their rated load, the metal parts of the wire, plug, socket, etc. will start to heat up, resulting in danger of burning. Accidents occur, which pose a potential threat to the safety of people's lives and property; therefore, the operator has set up an overload protection circuit in the plug, so that when the overload protection circuit senses that the current flowing through the plug is overloaded, the The overload protection circuit forms a power-off state for the plug, so that the current can no longer pass through the plug, which can prevent the circuit or power equipment from being burnt due to overload and heat, and increase the safety of the use of power equipment.

However, although the above overload protection circuit can be installed in the plug to achieve the expected effect of breaking the circuit to form a power-off state when overload occurs, it is also found in its actual operation and use. The overload protection circuit is connected with the circuit of the plug itself and the power terminal, which not only requires manual wiring, but cannot be automated, but also increases the overall volume of the plug, or requires additional molds, which are relatively difficult to make. The cost increases, and the overall manufacture of the plug is complicated and inconvenient, so that there is still room for improvement in the overall structural design.

Today, the creators uphold the rich experience in design, development and actual production in the related industry for many years, and then research and improve the existing technical means to provide a plug structure with overload protection, in order to achieve the purpose of better practical value.

The main purpose of this creation is to provide a plug structure with overload protection, which mainly uses a fixed seat combined with an overload protector to form a modular structure design, which can not only increase the production efficiency, but also use automated operations to conduct wire The crimping combination can relatively reduce the manufacturing cost, and make the overall volume smaller, more convenient to use, and more practical in its overall implementation and use.

The main purpose and effect of this plug structure with overload protection are achieved by the following specific technical means:

Its main system includes overload protector, fixed seat and shell; among which:

One side of the overload protector is electrically connected with two corresponding power terminals, and the power terminals are extended with a wiring portion for connecting wires, and the overload protector is provided with a reset switch, the reset switch is used for The overload protector in the open-circuit state returns to the on-state;

The fixing seat is combined and fixed outside the overload protector, and a through-slot hole is formed in the fixing seat corresponding to the power terminal of the overload protector, so that the power terminal can be penetrated through the through-slot hole, In addition, an opening is also formed on the fixing base corresponding to the reset switch of the overload protector, so that the reset switch is exposed from the opening;

The casing is covered and fixed with the fixing base and the overload protector, and the power terminal and the reset switch of the overload protector are protruded and exposed outside the casing.

The present invention is a preferred embodiment of a plug structure with overload protection, wherein the overload protector is an automatic power-off overload protector without fuse overload.

The present invention is a preferred embodiment of the plug structure with overload protection, wherein the fixed seat is composed of two corresponding seat bodies.

The present invention is a preferred embodiment of the plug structure with overload protection, wherein the shell is fixed outside the fixed seat by means of injection coating.

In order to make the technical content used in this creation, the purpose of creation and the effect achieved in this creation more completely and clearly disclosed, it is explained in detail below, and please refer to the disclosed drawings and drawing numbers together:

First of all, please refer to the schematic diagram of the partial three-dimensional decomposition structure of the creation in the first picture, the schematic diagram of the partial three-dimensional combined structure of the creation in the second picture, and the schematic diagram of the overall three-dimensional structure of the creation in the third picture. This creation mainly includes an overload protector. (1), the fixed seat (2) and the shell (3); of which:

The overload protector (1) is a non-fuse overload automatic power-off overload protector, and two corresponding power terminals (11) are electrically connected to one side of the overload protector (1), and are connected to the overload protector (1). The power terminal (11) is extended with a wiring portion (111) for connecting wires, and the overload protector (1) is provided with a reset switch (12), the reset switch (12) is used for the overload protector in an open circuit state (1) Return to the ON state again.

The fixing seat (2) is composed of two corresponding seat bodies (21), so that the two seat bodies (21) are combined and fixed outside the overload protector (1) to form a modular structure design , and a through-slotted hole (22) is formed in the fixing base (2) corresponding to the power supply terminal (11) of the overload protector (1), so that the power supply terminal (11) can pass through the through-slotted hole (22) A hole (23) is also formed in the fixing base (2) corresponding to the reset switch (12) of the overload protector (1), and the reset switch (12) is passed through the hole (23). ) is exposed.

The casing (3) is fixed on the outside of the fixing seat (2) by injection coating, and the fixing seat (2) and the overload protector (1) are covered and fixed by the casing (3). , and the power terminal (11) and the reset switch (12) of the overload protector (1) also protrude out of the casing (3).

In this way, in use, the power supply terminal (11) of the overload protector (1) can be plugged and combined with the mains socket to obtain power supply. Under abnormal conditions, if the passing current exceeds the rated value of the overload protector (1), the overload protector (1) will form an open circuit, so that the current can no longer pass through, which can prevent the connected electrical equipment from being burned and damaged. The situation occurs, and after the abnormal situation is eliminated, the reset switch (12) of the overload protector (1) can be pressed to make the overload protector (1) return to the conducting state again, so that the current can pass through again. supplied to the connected electrical equipment.
