Description

Improved structure of socket with early warning function

The present invention relates to a socket structure, in particular to a socket structure with an early warning function.

The socket structure is commonly used in daily life, and is the interface between electrical appliances and the mains. Due to the fixed position of the wall socket, another common socket structure exists in the form of an extension cord. The extension cord can be used to change the position or form of the socket, allowing users to flexibly plan the space and set the electrical appliances in the designated position. And get power coverage through extension cords.

Some extension cords are equipped with an overload protection switch. When the current carried by the extension cord exceeds the rated current, the overload protection switch will automatically trip and cut off the power to avoid damage caused by current overload. However, whenever the overload protection switch works, the overload protection switch is prone to mechanical damage, and it is also easy to damage the electrical appliances.

In view of this, one of the objectives of the present invention is to provide an improved socket structure that can provide early warning before current overload.

In order to achieve the above and other objectives, the present invention provides an improved structure of a socket with an early warning function, which has a rated current and includes a body, a plurality of socket units connected in parallel, a warning module, and a main control module. Some socket units, warning modules and main control modules are all set in the main body, and the main control module is used to detect the total current flowing through the socket units, and to control the alarm when the detected total current is higher than a predetermined current The module issues a warning, wherein the value of the warning current is lower than the rated current.

In this way, the improved socket structure of this invention can issue a warning before being overloaded, reminding the user that the electrical appliances set by the user are close to the rated current of the improved socket structure, so that the user does not continue to install more electrical appliances or remove unnecessary appliances. The electrical appliances used can prevent overload and protect the improved structure of the socket and electrical appliances.

Please refer to Figures 1 and 2 for the first embodiment of an improved structure of a socket with an early warning function created by the illustrated person. In this embodiment, the improved structure of the socket is an extension cord with a rated current. Generally speaking, the rated current of the extension cord should not exceed the rated current of the wall socket at the source end. Therefore, in normal use occasions, The rated current of the extension cord is usually equal to or less than the rated current of the wall socket at the source end, such as 15 amperes. In this embodiment, the improved socket structure includes a main body 10, a plurality of socket units 20 connected in parallel, a warning module 30 and a main control module 40. In addition, the improved structure of the socket can also include the cables and plugs required for plugging into the wall socket at the source end, but not shown in the drawing.

The main body 10 includes a pair of sliding rails 11 and at least one end cover 12 (two in this embodiment). The pair of sliding rails 11 are arranged in parallel, and the end cover 12 is respectively arranged on one end of the pair of sliding rails 11. Through the design of the slide rail and the end cover, the manufacturer can flexibly place different numbers, types, and specifications of socket units on the body, so that the improved structure of the socket can be manufactured in a modular manner, such as the embodiment shown in Figures 3 and 4 In this case, the number and specifications of the socket units 20 can be combined in different combinations, and the length of the slide rail 11 can also be adjusted according to requirements.

The socket units 20, the warning module 30, and the main control module 40 are all arranged on the main body 10. The socket unit 20 is slidably arranged between the pair of slide rails 11, and allows the socket unit 20 to face each other within a limited range. The main body 10 slides, and this can facilitate the user to more flexibly insert electrical plugs of different sizes.

The main control module 40 is used to detect the total current flowing through the socket units 20, and is used to control the warning module 30 to issue a warning when the detected total current is higher than a warning current. The warning module 30 may be, for example, a buzzer A warning sound or warning light can be emitted by the device or warning light. The value of the early warning current is lower than the rated current. For example, the value of the early warning current is a value between 60% and 99% of the rated current, and for example, is between 70% and 95% of the rated current. A value between %, for example, is a value between 80% and 90% of the rated current. In this embodiment, the warning module 30 is a set of warning lights. As the total detected current increases, the number of warning lights emitting warning lights increases. For example, the value of the warning current is the rated current. One warning light is on when 50% of the current is below 50%, two warning lights are on when the value of the pre-warning current is 50-60% of the rated current, and three warning lights are on when the value of the pre-warning current is 60-70% of the rated current. , When the value of the early warning current is more than 80% of the rated current, four warning lights are on.

Please refer to FIG. 5, which shows another embodiment of the improved structure of the socket. It is a wall socket. The main body 10 is also provided with a warning module 30 and a main control module 40 similar to the previous embodiment. .

Based on the above description, the improved socket structure of this invention can issue a warning before being overloaded, reminding the user that the electrical appliances installed by the socket are close to the rated current of the improved socket structure, so that the user does not continue to install more electrical appliances or remove non-electrical appliances. The necessary electrical appliances can prevent overload and protect the improved structure of the socket and electrical appliances.
