Description

  The present invention relates to a hot-wire elastic piece, a live-wire conductive piece, and a neutral-wire elastic piece when the hot-wire elastic piece and the hot-wire conductive piece are overheated or when the neutral-wire elastic piece and the neutral wire conductive piece are overheated. The present invention relates to a temperature-destroying protective member and an outlet using the same.

  In order to prevent the occurrence of current overload, short circuit, overheating, etc. in the circuit, fuses and breakers are usually installed on the circuit, and when the temperature of the circuit is too high or the current is too high, the fuse It is melted under the influence, or the metal elastic piece of the breaker trips, forming an open circuit in the electric circuit and cutting off the current, ensuring safety when using the electric power.

  The “insulation-type temperature rising fracture fixing piece and the plug and outlet using the insulation-type temperature rising destruction fixing piece” described in Patent Document 1 are configured such that the edge-type temperature rising destruction fixing piece includes a connecting member and two connecting members. The two restricting members coupled to the ends form an H-shaped structure, the connecting member is installed in a groove formed on the conductive piece, and the two restricting members are opposed to the two conductive members. The two conductive members are brought into contact with each other and the two conductive members are brought into contact with each other to regulate the position. The connecting member is broken when overheated, and a cut state is formed between the two conductive members.

By the way, when a load (electrical appliance) is connected between a hot wire conductive piece and a neutral conductive wire piece, the electric current is hot elastic piece, hot conductive piece, load (electrical), neutral conductive piece and neutral. A current path is formed through the wire elastic pieces in order.
However, as shown in FIG. 21, the one described in Patent Document 1 uses a temperature rising fracture fixing piece for each live wire elastic piece and live wire conductive piece. Another temperature-programmed fracture fixing piece is used for the conductive wire conductive piece.
Therefore, when the overheated position is between the neutral wire elastic piece and the neutral wire conductive piece, the fixing piece between the neutral wire elastic piece and the neutral wire conductive piece is destroyed by the temperature rise, If the fixed piece located between the hot-wire elastic piece and the hot-wire conductive piece is not broken, the high current before the current cut state is formed enters the load, and the load is leaked, When an operator touches the load in a grounded state, the operator may get an electric shock.

Further, in the embodiment shown in FIGS. 1, 2 and 3 of Patent Document 2, independent position regulation between a live wire conductive plate and a live wire contact portion is performed. A limiting element is used, and a separate and independent positioning element is also used between the neutral wire conductive plate and the neutral wire contact portion. ing.
For this reason, the problem that exists in the structure described in Patent Document 1 also exists in this structure, and only the position regulating member between the neutral wire conductive piece and the neutral wire contact portion under the overheating condition. There is a possibility that the position restricting member between the live wire conductive piece and the live wire contact portion is completely maintained. Further, the structure of the position restricting member is the same material and the thickness is almost the same, and the structure strength is relatively high. Therefore, the position restricting member is not easily broken, and it is broken according to factors such as the expected position and time to receive heat. Hateful.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
A first embodiment of the present invention is shown in FIGS.
As shown in FIG. 1, the temperature-destroy-protecting member 10 according to the first embodiment includes a first restricting member 1, a second restricting member 2, a connecting member 3, and at least one to-be-destructed portion 4.
The first restricting member 1, the second restricting member 2, and the connecting member 3 are selected from materials that are easily damaged by heat, such as plastic materials. The material to be thermally destroyed is desirably destroyed at 80 ° C. to 299 ° C.
Both ends of the connecting member 3 are connected to the first restricting member 1 and the second restricting member 2 that are extended as a single body, and the temperature rising destruction type protective member 10 has a substantially H-shaped structure.
The number of the parts to be destroyed 4 in this embodiment is two and is located at both ends of the connecting member 3, but the position is not limited to this.

As shown in FIG. 2, the connecting member 3 includes a to-be-destructed portion 4 provided at both ends and an intermediate portion 31 that connects the to-be-destructed portions 4 at both ends, and the thickness T of the to-be-destructed portion 4 has an intermediate portion 31. Is smaller than the thickness T ′. In this way, the destructible portions 4 having relatively low mechanical strength can be formed at both ends of the connecting member 3 by reducing the thickness. However, the present invention is not limited to this, and other portions such as defects such as holes may be formed. A part may be installed.
In short, any position where the part to be destroyed 4 is located can be defined as the first part S1, and any part other than the position where the part 4 is destroyed can be defined as the second part S2. The portion S1 is a fragile portion that is more easily destroyed by heat than the second portion S2.

As shown in FIG. 3 and FIG. 4, the temperature-destroying protection member 10 regulates the position by bringing the hot-wire elastic piece 5 and the hot-wire conductive piece 6 into contact with each other, and the neutral-wire elastic piece 7 and the neutral wire 10. It is used for regulating the position of the line conductive pieces 8 in contact with each other.
A first recess 61 is formed on the live wire conductive piece 6, a second recess 51 is formed on the live wire elastic piece 5, a third recess 81 is formed on the neutral wire conductive piece 8, and a neutral wire elastic piece is formed. A fourth recess 71 is formed at 7. The width W of the first recess 61 is preferably greater than the width W ′ of the second recess 51, and the width W of the third recess 81 is preferably greater than the width W ′ of the fourth recess 71. Thereby, sufficient space is provided so that the movement of the connecting member 3 after being destroyed is not hindered.

In order not to prevent the movement of the connecting member 3 after being destroyed, the live wire conductive piece 6 and the neutral wire conductive piece 8 may be implemented in other forms.
For example, as shown in FIG. 3A, the hot-wire elastic piece 5A and the hot-wire conductive piece 6A are brought into contact with each other to regulate the position, and the neutral-wire elastic piece 7A and the neutral wire conductive piece 8A are brought into contact with each other. The first concave portion 51A is formed in the live wire elastic piece 5A, the second concave portion 71A is formed in the neutral wire elastic piece 7A, and the length of the live wire conductive piece 6A and the neutral wire conductive piece 8A is extended. Does not exceed the first recess 51A and the second recess 71A.

  As shown in FIGS. 3 and 4, at the time of assembly, first, a force F is applied to bend the live elastic piece 5 inward to abut the live conductive piece 6, and the neutral elastic piece 7 After being bent inward and brought into contact with the neutral wire conductive piece 8, the first restricting member 1 and the second restricting member 2 are brought into contact with the outer surface of the live wire elastic piece 5 and the neutral wire elastic piece 7, respectively. In addition, by accommodating the connecting member 3 in the first concave portion 61, the second concave portion 51, the third concave portion 81, and the fourth concave portion 71, the position of the hot-wire elastic piece 5 and the neutral wire elastic piece 7 that are elastically deformed, respectively, is regulated. Then, the hot wire elastic piece 5 and the hot wire conductive piece 6 are brought into contact with each other, and the neutral wire elastic piece 7 and the neutral wire conductive piece 8 are brought into contact with each other.

  As shown in FIG. 3 and FIG. 5, the temperature rises during overheating between the hot wire elastic piece 5 and the hot wire conductive piece 6 or overheating between the neutral wire elastic piece 7 and the neutral wire conductive piece 8. Since the destructible protective member 10 is provided with the destructible portion 4 that is relatively easily destroyed in advance, the destructible protective member 10 is first destroyed from the destructible portion 4, and the first restricting member 1, the second restricting member 2, and the connecting member 3 are original. The active line elastic piece 5 and the live wire conductive piece 6, and the neutral wire elastic piece 7 and the neutral wire conductive piece 8 are separated at the same time.

FIG. 6 shows a second embodiment of the present invention.
The temperature-destroy-protective member 10A of Example 2 has substantially the same structure as that of Example 1, and includes a first restricting member 1A, a second restricting member 2A, a connecting member 3A, and two to-be-destructed parts 4A.
Both ends of the connecting member 3A are also connected to the first restricting member 1A and the second restricting member 2A, and the temperature rising destructive protection member 10A has an approximately H-shaped structure.
The main difference from the first embodiment is that both the first restricting member 1A and the second restricting member 2A are made of a metal material, the connecting member 3A is made of a plastic material, and the two to-be-destructed parts 4A are connected to the connecting member 3A. Between the first restricting member 1A and between the connecting member 3A and the second restricting member 2A, the first restricting member 1A and the second restricting member 2A made of metal are used to make heat transfer more uniform and rapid. Thus, it is possible to ensure that the to-be-destructed portion 4A is destroyed when the current path is overheated.
More specifically, the first restricting member 1A and the second restricting member 2A are provided with insertion columns 11A and 21A extending, respectively, and fitting grooves 32A are formed at opposite ends of the connecting member 3A. The fitting pillars 11A and 21A are fitted in correspondence with the fitting grooves 32A, thereby providing a relatively large contact area and making the to-be-destructed portion 4A more easily broken when the temperature rises.

7 to 9 show a third embodiment of the present invention.
As shown in FIG. 7, the temperature-destroy-protective member 10B of the third embodiment includes the first restricting member 1B, the second restricting member 2B, the connecting member 3B, and the two to-be-destructed portions 4B, as in the first embodiment. . The first restricting member 1B, the second restricting member 2B, and the connecting member 3B are all made of a plastic material, and the main difference is that the first restricting member 1B and the second restricting member 2B are all ring members. The thickness of one part is made thinner than the other part, and the to-be-destructed part 4B is formed.

As shown in FIGS. 8 and 9, the temperature-destroying protection member 10B also regulates the position by bringing the hot-wire elastic piece 5B and the hot-wire conductive piece 6B into contact with each other, and the neutral-wire elastic piece 7B and the neutral member. It is used for regulating the position of the line conductive pieces 8B in contact with each other.
At the time of assembly, first, a force F is applied so that the live wire elastic piece 5B is brought into contact with the live wire conductive piece 6B and the neutral wire elastic piece 7B is brought into contact with the neutral wire conductive piece 8B. The regulating member 1B is fitted to the tip of the hot-wire elastic piece 5B, and the second regulating member 2B is fitted to the tip of the neutral-wire elastic piece 7B, so that the hot-wire elastic piece 5B and the neutral-wire elastic piece 7B are positioned. The hot wire elastic piece 5B and the hot wire conductive piece 6B are brought into contact with each other, and the neutral wire elastic piece 7B and the neutral wire conductive piece 8B are brought into contact with each other.

FIGS. 10-13 shows another example of use of the thermal destruction-type protective member 10B of Example 3. FIG.
A difference from the third embodiment is that, as shown in FIGS. 10 and 11, a first bent portion 51C bent inward is formed at one end of the hot-wire elastic piece 5C, and the first bent portion 51C has a first bent at the upper end. A groove portion 52C is provided, whereby the first insertion portion 53C is erected on the first bent portion 51C, and the first restriction member 1B is fitted to the first insertion portion 53C.
In addition, a second bent portion 71C that is bent inward is also formed at one end of the neutral linear elastic piece 7C, and a second groove portion 72C is provided at the upper end of the second bent portion 71C, whereby the second bent portion 71C is formed on the second bent portion 71C. The second insertion portion 73C is erected, and the second restriction member 2B is fitted to the second insertion portion 73C.
As shown in FIGS. 12 and 13, by changing the lengths of the first bent portion 51C and the second bent portion 71C, the thermal breakdown type protective member 10B has a single dimension and a hot wire arranged at different intervals. It can be applied to the elastic pieces 5F, 5G / live wire conductive pieces 6F, 6G, and neutral wire elastic pieces 7F, 7G / neutral wire conductive pieces 8F, 8G.

FIG. 14 shows a fourth embodiment of the present invention.
The temperature rising destruction type protective member 10C of the fourth embodiment also includes a first restriction member 1C, a second restriction member 2C, a connecting member 3C, and a plurality of parts to be broken 4C, and any of the first restriction member 1C and the second restriction member 2C. Is also a ring member, and both ends of the connecting member 3C are connected to the first restricting member 1C and the second restricting member 2C, respectively. Most of the first restricting member 1C, the second restricting member 2C, and the connecting member 3C are made of a plastic material.
The main difference from the third embodiment is that a part of the ring member is made of a metal material, and the portion to be destroyed 4C is formed at the ring member portion. Thereby, it is possible to make the heat conduction more uniform and rapid by the metal material portion and to ensure that the to-be-destructed portion 4C is destroyed when the current path is overheated.

More specifically, each of the first restricting member 1C and the second restricting member 2C includes plastic main parts 12C and 22C. The outer end surfaces of the main portion 12C of the first restricting member 1C and the main portion 22C of the second restricting member 2C are both formed with recessed openings 13C and 23C, and the opening directions of the recessed openings 13C and 23C are opposite to each other. Yes.
Further, both the first regulating member 1C and the second regulating member 2C further include metal heat conducting members 14C and 24C. The metal heat conducting members 14C and 24C are fixedly connected to the main portions 12C and 22C by a coupling method such as fitting and adhesion, and close the openings of the recesses 13C and 23C. The first regulating member 1C and the second regulating member 2C are the ring members. In particular, the number of to-be-destructed parts 4C in the present embodiment is two, but this is not a limitation, and only one may be used.

FIG. 15 shows an outlet in which the temperature-destroying protective member 10 of Example 1 is used for overheat protection. The outlet includes an insulating main body 20A, a live wire conductive piece 30A, a neutral wire conductive piece 40A, a live wire elastic piece 50A, and a neutral wire elastic piece 60A.
The insulating main body 20A includes at least one pair of opposed live wire insertion ports 201A and neutral wire insertion ports 202A. The hot wire conductive piece 30A is installed in the insulating main body 20A and corresponds to the hot wire insertion port 201A. The neutral wire conductive piece 40A is installed in the insulating main body 20A and corresponds to the neutral wire insertion port 202A. The hot wire elastic piece 50A is installed in the insulating main body 20A and corresponds to the hot wire conductive piece 30A. The neutral wire elastic piece 60A is installed in the insulating main body 20A and corresponds to the neutral wire conductive piece 40A.

  When the positions of the hot-wire elastic pieces 50A and the neutral-wire elastic pieces 60A are regulated and fixed using the temperature rising destruction type protective member 10, the hot-wire elastic pieces 50A and the hot wires are used as described in the first embodiment. When overheated between the conductive pieces 30A or overheated between the neutral wire elastic pieces 60A and the neutral wire conductive pieces 40A, the temperature-destroying type protective member 10 is provided with a destructible portion 4 that is relatively easy to break. Therefore, the to-be-destructed part 4 is destroyed first, the first restricting member 1, the second restricting member 2 and the connecting member 3 lose their original position restricting action, and the hot-wire elastic piece 50A and the hot-wire conductive piece 30A, neutral wire elastic piece 60A and neutral wire conductive piece 40A are separated simultaneously.

FIG. 16 shows an example of a change in the outlet.
The hot wire conductive piece 30A includes a plurality of hot wire insertion portions 301A, the hot wire conductive piece 30A and one hot wire elastic piece 50A are in contact, and the neutral wire conductive piece 40A has a plurality of neutral wire insertion portions 401A. The neutral wire conductive piece 40A and one neutral wire elastic piece 60A are in contact with each other, and the live wire conductive piece 30A, the live wire elastic piece 50A, the neutral wire conductive piece 40A, and the neutral wire elastic piece 60A are under normal conditions. Therefore, the position is regulated by the first regulating member 1, the second regulating member 2 and the connecting member 3 together.
With such a structure, overheating protection can be performed on the plurality of hot wire insertion portions 301 </ b> A and the neutral wire insertion portions 401 </ b> A with the single temperature rising destruction type protection member 10.
