Description

Component and method for sharing thermal damage fixing member with multi-conductive slot

The invention relates to a component and a method for sharing a thermal break fixing member with a multi-conductive slot, in particular, the multi-conductive slot shares a thermal break fixing member, and when any one of the conductive slots reaches a respective limit operating temperature, The component and method for destroying the thermal damage fastener to the predetermined temperature.

Avoid circuit overload, short circuit, overheating, etc., usually have a fuse or breaker on the circuit. When the circuit temperature is too high or the current is too high, let the fuse be affected by high temperature and blow or let the breaker The metal shrapnel jumps off to make the circuit form an open circuit and power off, thus ensuring the safety of electricity.

Regarding the related structure of the fuse structure, for example, there is a "temperature fuse connection structure" of the Republic of China Invention Patent Publication No. I371053, which mainly includes two terminals connected to each other to form a passage, and a hot-melt metal is coupled to the two terminals. When the current is overloaded, the circuit is overheated, or the ambient temperature used is too high, the hot melt metal is heated and the temperature rises and melts and fractures, so that the two terminals are not connected to each other to form an open state. .

However, in the case of the I371053 patent, there are at least the following disadvantages, including: 1. Except for a few metal elements such as antimony, tin, indium and alkali metals, most of the metals have a melting point above 300 ° C, for example, the melting point of copper is 1084.6 ° C, the melting point of iron is 1535 ° C; in the above-mentioned I371053 patent, if the metal having a melting point of 300 ° C or less is selected as the hot-melt metal, there is a problem that the bonding strength is insufficient, and the two terminals cannot be firmly combined, and Even if the strength of the bond is available, there will be a problem of excessive price. 2. The hot-melt metal is a conductive material. When the hot-melt metal is melted, if the hot-melt metal portion is stuck to the two terminals, the residual hot-melt metal is also liable to cause false contact between the two terminals, and thus cannot be completely Power off. Or the hot melt metal that is blown and split may be bounced off by the two terminals that are opened to form an open circuit, and thus the object is accidentally contacted to cause a short circuit, and the use is still dangerous.

In addition, U.S. Patent No. US9257798 "SOCKET HAVING OVERHEATING DESTRUCTIVE LIMITING ELEMENT", which discloses that each socket can be insulated with a limiting member to form a passage; when one of the sockets is overheated When the associated limit member breaks the break, the overheated socket is broken due to the relative opening of the conductive member.

However, in the previous case of M433670, the distance between each slot and the overload protection switch is different. Therefore, in actual use, each slot under the influence of the heat conduction distance has a certain temperature difference from the overload protection switch, and the overload protection switch is more The temperature difference between the far slot and the overload protection switch is larger, so that the overload protection switch is not easy to be powered off when the slot temperature of the far end is too high, and there is still a problem of insufficient safety in use.

It can be seen from Table 1 that the "heat conduction portion" described in the above tenth embodiment is set at position 7, and the position 10 represents a socket, and the load is connected at the same time, and the limit operating temperature of the position 10 is set to 99.6 to 102.3 °C. Between the conditions, the preset temperature of the thermal destruction fixture of position 7 should be between 75.3 and 79.3 °C. According to Table 1, by setting "heat conduction position" between position 1 and position 10, it is possible to effectively balance any of position 1 to position 10, and to limit the operating temperature of any of position 1 to position 10, None of them is too different from the preset temperature of the heat-damping fixture, which is one of the main features of the present invention.

Table 2 (unit: °C)

It can be seen from Table 2 that when the working temperature of the position 10 reaches 200 ° C, the "heat conduction portion" described in the above tenth embodiment is set at the position 5, and when the working temperature of the position 10 is between 202.1 and 203.4 ° C, The temperature difference between position 10 and position 5 will be between 48.8 and 51.1 °C depending on the working time, and the temperature difference between position 1 and position 5 will be between 40.5 and 41.2 °C depending on the working time. As can be seen from Table 2, when the operating temperature of the position 10 is around 200 ° C, if the "heat conduction portion" is set between the position 5 and the position 6, the limit operation of any of the positions 1 to 10 can be effectively taken into consideration. The temperature is such that the difference between the preset temperature and any of the extreme operating temperatures does not exceed 55 °C.

Table 3 (unit: °C)

Similarly, as shown in Table 3, when the operating temperature of the position 10 reaches 300 ° C, if the "heat conduction portion" described in the above tenth embodiment is set between the position 5 and the position 6, the position 1 can be effectively taken into consideration. The limit operating temperature to any of the positions 10 is such that the difference between the preset temperature and any of the limit operating temperatures does not exceed 60 °C.

According to Table 1, Table 2 and Table 3, if the limit working temperature is defined as a “limit operating temperature”, the farther the distance between “heat conduction” and “limit operating temperature”, the two The difference in temperature will be greater. Therefore, by setting the "heat conduction portion" between the position 1 and the position 10, it is possible to effectively balance any of the positions 1 to 10, and the limit operating temperature of any of the positions 1 to 10 can be The preset temperature difference with the heat-damaged fixture is maintained within a certain range, which is one of the main features of the present invention. The present invention is applicable to an embodiment having two or more sockets, the socket sharing a thermal break fixing member, and any of the sockets being overheated can cause the heat-damaged fixing member to be broken and powered off. Taking the extension cord socket as an example, the operating temperature exceeding 300 °C may cause the plastic casing or plastic fitting of the extension cord socket to be deformed by heat fusion, resulting in safety concerns. Therefore, in the present invention, the aforementioned limit operating temperature is between 80 and 300 ° C, and the temperature at which the thermal break fastener is destroyed, that is, the predetermined temperature is between 79 and 299 ° C.

In Table 1, the positions adjacent to each other have a minimum difference of zero, for example, position 1 and position 2 are at a temperature of 25 minutes. That is, for a copper piece having a length of 30 mm, the position 1 and the position 3 respectively represent the socket, and the measuring point or the heat conducting position of the preset temperature of the heat-damping fixing member is set at the position 2, if the heat destroys the fixing member The breaking temperature, that is, the preset temperature is set to 51.8 ° C, the limit operating temperature of position 1 will be 51.8 ° C, and the limit operating temperature of position 3 will be 52.5 ° C. This means that the shorter the copper piece, according to the features of the present invention, the "heat conduction" is placed between the two socket positions, which can maintain the minimum working temperature between the two socket positions and the preset temperature can be kept to a minimum. difference.
