Description

Conductive clip fixing structure of the socket

The present invention relates to a fixing structure for a socket which can hold the conductive clip and the conductive sheet tightly to each other without causing relative displacement.

At present, sockets used in general electrical appliances, such as adapter sockets, expansion sockets and extension cord sockets, etc., are often provided with an overload protector on the circuit connection of the socket in order to avoid a dangerous situation such as current overload, overheating or fire. . When the operating temperature of the circuit is too high or the current is too large, the overload protector can be powered off due to the influence of high temperature, thereby ensuring the safety of power consumption. However, each expansion socket and each extension cable socket usually have multiple sets of "socket units", one set of "socket units" for one plug, and multiple sets of "socket units" share an overload protector, once the overload When the protector is powered off, all the "socket units" are powered off, which may cause inconvenience in use. Moreover, once all power is turned off at the same time, the user cannot know clearly whether there is a problem with the group of "socket units". Even if the group of "socket units" is known to be powered off, it is impossible to know whether it is a "socket unit". The failure of the conductive clips or the short circuit caused by the failure of the electrical appliances itself is not ideal for use.

Therefore, in view of this, the creators of this creation have applied for the patent No. M477079 “Overheat-damaged safety structure and socket and plug with overheat-damaged safety structure” announced by the Republic of China on April 21, 103. As shown in Figure 17. It is revealed that a firewire terminal (B) extends with a firewire spring piece (B1), and a relatively open breaking position is preset between the fire wire spring piece (B1) and a fire wire copper piece (B2). The fire wire spring piece (B1) and the fire wire copper piece (B2) are brought into contact with each other by a stopper (D) to form a passage position, and the fire wire spring piece (B1) is provided with a return elastic force. The other neutral terminal (C) extends with a neutral elastic piece (C1), and the neutral wire spring piece (C1) and the neutral wire copper piece (C2) are preset with a relatively open breaking position, and The neutral elastic piece (C1) and the neutral wire copper piece (C2) are brought into contact with each other by another limiting piece (D) to form a passage position, and the neutral wire elastic piece (C1) has a reply. elastic force. Moreover, the fire wire spring piece (B1) and the neutral wire spring piece (C1) are provided with a resilience by bending the material, and the resilience elastic force is used to make the fire wire spring piece (B1) and the fire wire copper piece (B2) The open state is formed when the opening is relatively open, and the neutral wire spring piece (C1) and the neutral wire copper piece (C2) are relatively opened as necessary to form the open state.

Since the fire wire copper piece (B2) and the fire wire spring piece (B1) are in sufficient contact with each other by the clamping member (D), the neutral wire copper piece (C2) and the neutral wire spring piece are simultaneously (C1) is also in sufficient contact with each other by the clamping of the other limiting member (D), so that the electric conduction effect is better, and the temperature generated by the conduction current can be effectively reduced. When any one of the extension cord sockets (E) is overloaded, or the circuit is short-circuited, and the circuit is overheated, the contact portion of the hot-wire copper piece (B2) with the live-wire spring piece (B1), or the neutral wire copper piece (C2) The operating temperature of the contact portion with the neutral elastic piece (C1) reaches the heat distortion temperature (for example, 120 ° C), so that the second stopper (D) is deformed by the heat distortion temperature and is deformed. At this time, the live wire spring (B1) will be away from the hot wire copper piece (B2) by the above-mentioned return elastic force, or the neutral wire elastic piece (C1) is away from the neutral wire copper piece (C2) by the above-mentioned return elastic force. To change the path position to a disconnect position to interrupt the supply of current and avoid the operating temperature continues to rise. Since the two limiting members (D) are non-conductive materials, when the two limiting members (D) are deformed by heat, and even split into two, the constrained member (D) after the destruction is absolutely not caused by Accidental contact with surrounding electronic components creates a short circuit, making it safer to implement.

However, since the two conductive clips are used to accept the pin insertion of the plug. If there is no good fixed structure, when the pins of the plug are inserted and pulled, the displacement of the two conductive clips is easily caused, and the contact surface of the two conductive clips is shaken, which easily causes the limit member (D) to loosen. It is necessary to improve it.
