Description

Overheat damage switch, overheat damage assembly, socket with switch

This creation is about a kind of overheat damage switch, overheat damage component, socket with switch, especially a kind of power failure structure different from fuse and different from bimetal. The creation of overheated damage piece does not depend on current to execute. Destruction, and the destruction is performed by thermal energy transfer and the switch is powered off.

The conventional rocker switch is a reciprocating pivot of the control switch in a certain angle range to control the passage and open circuit of the switch. For example, the Republic of China Patent No. 560690 "Spark shielding structure of the switch" is utilized when the switch is pivoted. The locating feature positions it in a first position or a second position to form a path or an open circuit.

The conventional pressing switch can repeatedly control the passage and the breaking of the switch by each pressing operation, and the button utilizes a reciprocating button structure similar to the conventional automatic ball pen, so that the button of the switch is positioned at the lower position each time the pressing is pressed. Or the upper position, such as the one disclosed in Chinese Patent No. CN103441019 "Button Switch".

In the Republic of China Patent No. 321352 "online switch structure improvement" discloses a switch structure with a fuse, but the fuse is located in the path of the power line, and needs to rely on the current to pass the protection, especially the overload current can have a chance to melt The fuse is broken. Since the fuse needs to pass current when it is working, it must be melted when the current is too large. Therefore, a low-melting lead-tin alloy and zinc are often used as fuses, and the conductivity is far less than that of copper. Take the extension cable socket as an example, extend the cable plug The main use of copper as a conductor, if the extension cord socket combined with the switch of the Republic of China patent No. 321352 to control the power supply, the fuse's conductivity is not good, it is easy to have energy consumption.

In the Republic of China Patent No. M382568 "Double-pole automatic power-off safety switch" discloses a bimetal type overload protection switch, but the bimetal must also be in the path through which current flows, and it is necessary to rely on current to generate deformation. In particular, the current that needs to be overloaded can deform the bimetal and interrupt the circuit.

The Republic of China Patent No. M250403 "Overload Protection Switch Structure for Group Sockets" discloses that the overload protection switch is applied to an extension cord socket. The overload protection switch of the patent case is provided with a bimetal, when the entire extension cord socket is When the power exceeds, the bimetal is automatically tripped due to thermal deformation to achieve the function of power failure protection. However, the bimetal must rely on current to pass the overload protection, and the bimetal has much lower conductivity than copper, so it is also prone to energy consumption.

However, in addition to the current overload can cause overheating, in the case of extension cord outlets, the following conditions may cause overheating of any outlet, including:

1. The metal pins of the plug are severely oxidized, and the metal pins are covered with oxide. When the plug is inserted into the socket, the poorly conductive oxide makes the resistance become large and the socket is overheated.

2. When the metal pin of the plug is inserted into the socket, the insertion is incomplete, resulting in only partial contact, and too small contact area causes the socket to overheat.

3. The metal pins of the plug are deformed or worn, resulting in incomplete contact when the socket is inserted, and too small contact area causes the socket to overheat.

4. The metal piece of the plug or the metal piece of the socket is contaminated with foreign matter, such as dust or dirt, so that the conductivity is not good, so the resistance becomes large and overheats.

Under the above conditions, there is a serious difference between the operating temperature at the outlet and the operating temperature at which the overload protection switch is located.

In the case of "Assembly and method of plural conductive slots sharing an overheating destructive fixing element", the creator has exposed the experiment of the difference between the distance and the temperature of the copper sheet. It is known from the test of the US9698542 patent TABLE 2 if The above overheated socket is located at position 10 of the TABLE2 experiment. The above overload protection switch is located at position 1 of the TABLE 2 experiment. When the distance between the two is 9 cm, the operating temperature of the socket reaches 202.9 ° C. After 25 minutes, the operating temperature of the overload protection switch is also Only 110.7 ° C. That is, when the socket is 9 cm away from the overload protection switch, when the working temperature of the socket has been overheated to 202.9 ° C and there is the possibility of accidental burning, the bimetal of the overload protection switch is still only 110.7 ° C, which has not reached the deformation temperature, overload protection. The switch does not automatically trip and power off.

There are many kinds of situations in which the socket is overheated, and the distance between the socket and the bimetal of the overload protection switch causes a great temperature difference. Therefore, in order to effectively achieve overheat protection, overload protection should be provided on each socket of the extension socket. The bimetal of the switch, but the bimetal type overload protection switch is relatively expensive, and if it is set on each socket of the extension cord socket, the price will rise sharply, which is not conducive to popular use.

The second elastic member has a second elastic force acting on the operating member. When the operating member is in the first position, the first elastic force forces the contact member to press against the movable conductive member, so that the movable conductive member contacts the second conductive member to form an energized state, and in the energized state, the current Passing the first conductive member, the movable conductive member and the second conductive member And generating a thermal energy, the heat energy is transmitted to the thermal damage device via the contact member and the first elastic member, and the to-be-destroyed portion absorbs the thermal energy and is destroyed at the destruction temperature, so that the to-be-destroyed portion is subjected to the first The elastic member is pushed against the displacement space, so that the first elastic force is thus reduced or lost. At this time, the second elastic force is greater than the first elastic force, and the second elastic force forces the operating member to move to a first In the second position, the movable conductive member is thus separated from the second conductive member to form a power-off state.

Further, the operating member further includes a limiting member that defines a space for the cylinder, the limiting member abuts the overheating breaking member, and the overheating breaking member is fixedly disposed at the assembly position; The elastic member is loaded into the space.

Further, the first elastic member is a spring, and the first end of the first elastic member is sleeved on the set of the overheat breaking member.

Further, the contact member is a hollow heat conducting housing, the contact end contacts the movable conductive member, and the second end of the first elastic member protrudes into the contact member.

The two ends of the second elastic member (7A) are respectively sleeved on the first convex portion (63A) and the second convex portion (10A).

Referring to the third figure in conjunction with the first figure, the method of assembling the overheated damage member (5A) will be described in further detail below: the above-described overheated damage member (5A) is disposed so as to be placed in the receiving tube portion (611A) of the aforementioned operating member (61A) The inside shape; the overheat breaking member (5A) is loaded from the opening (6112A) of the accommodating tube portion (611A) such that the overheating breaking member (5A) is located at an assembly position away from the opening (6112A) (6111A) The heat-damping member (5A) is fixed in the assembled position (6111A) enough to resist gravity without leaving the assembly position (6111A). For example, the connecting portion (51A) is formed by a fitting portion (511A) (for example, a connecting portion (51A) and the receiving portion The fixing portion (611A) is fixed to the portion to be tightly fitted, or the fitting portion such as the concave-convex fitting portion can be fixed or fixed by an adhesive (512A) (for example, a sticky substance such as adhesive or grease).

(53A), under the action of the first elastic force, the portion to be broken (52A) of the overheat breaking member (5A) is pressed by the first elastic member (62A), and gradually moves toward the displacement space (531A) Displacement, causing the first elastic force to become smaller or lost, and the second elastic force is greater than the first Elastic force. In this embodiment, the direction in which the first conductive member (2A) and the second conductive member (3A) are arranged is defined as a longitudinal direction, and the operating member (61A) has a length in the longitudinal direction, and the first elastic member ( 62A) is disposed at a central position of the length, and the second elastic member (7A) is at a distance from the central position at the set position of the length. Therefore, when the second elastic force is greater than the first elastic force, the operating member (61A) can be pivoted by the pivot point (610A) due to the action of the moment, and the contact member (612A) is driven at the tilt. The plate conductive member (4A) slides, thereby forcing the operating member (61A) to move to the closed position, and the silver contact (41A) of the rocker conductive member (4A) is thus separated from the second conductive member (3A). A power-off state is formed, thereby achieving the effect of overheat protection.

The piece (4B) is selectively contacted or separated from the second conductive member (3B) in a rocker type. When the contact member (612B) slides on the rocker conductive member (4B) toward a silver contact (41B) on the rocker conductive member (4B), the first elastic force will force the silver The contact (41B) contacts the second conductive member (3B) to form an energized state.

The main difference is that the operating member (61B) further includes a limiting member (613B) defining a space (6131B), for example, a cylinder, by which the limiting member (613B) is damaged by overheating. The member (5B) can also be disposed at the assembly position (6111B) of the accommodating tube portion (611B), and is not limited to the use of the adhesive or the fitting portion described in the first embodiment; An elastic member (62B) is fitted into the space (6131B).
