Unless the context clearly dictates otherwise, expressions in the singular include expressions in the plural. In the present application, the terms "including" or "having" and the like should be understood to specify the presence of the features, numerals, steps, actions, structural elements, components, and combinations thereof described in the specification, and not to preclude the presence or addition of one or more other features, numerals, steps, actions, structural elements, components, and combinations thereof.
Unless otherwise defined, all terms including technical or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a structural view schematically showing a circuit breaker including a terminal structure according to an embodiment of the present invention, and fig. 2 is a structural view schematically showing a state in which the terminal structure is separated in the circuit breaker of fig. 1.
As shown in the drawing, a terminal mounting portion 1100 is formed on one surface of the circuit breaker 1000. In a state where the terminal structure 2000 is in contact with the terminal mounting portion 1100, the terminal structure 2000 is fixed to the terminal mounting portion 1100 by a fixing member.
In addition, the terminal structure body 2000 includes a center terminal structure body 2100 and a side terminal structure body 2200. The side terminal structure body 2200 may be positioned at one side of the central terminal structure body 2100, or the side terminal structure bodies 2200 may be disposed at both sides of the central terminal structure body 2100 to be symmetrical to each other.
Fig. 1 and 2 illustrate an embodiment of the above-described structure, in which the terminal structure 2000 is combined with the circuit breaker 1000 in such a manner that the side terminal structure 2200 symmetrical to each other is positioned at both sides of the central terminal structure 2100.
Next, referring to fig. 3 to 5, the detailed technical structure, shape and close-coupled structure of the terminal structure of the present invention will be described in further detail.
Fig. 3 is a schematic structural view showing a side terminal structure of the terminal structure shown in fig. 2, and fig. 4 is a schematic structural view showing a connection state in which the side terminal structure shown in fig. 3 is connected to a breaker.
As shown, the side terminal structure body 2200 includes a side plate terminal 2210 and a side T-shaped terminal 2220.
The side T-shaped wire terminals 2220 are generally "T" shaped.
A side T-shaped terminal 2220 is coupled to one side surface of the side plate terminal 2210, and the side plate terminal 2210 is coupled to a side portion of the circuit breaker 1000.
More specifically, the side plate-shaped terminal 2210 is formed in a plate shape, and the first heat sink LH1 is mounted on the side plate-shaped terminal 2210. For this, a circuit breaker is coupled to one side surface of the side plate terminal 2210, and a first heat sink LH1 and a side T-shaped terminal 2220 are coupled to the other side surface of the side plate terminal 2210.
In addition, the side T-shaped connection terminal 2220 may be coupled to one side of the other side surface of the side plate-shaped connection terminal 2210, and the first heat sink LH1 may be coupled to the other side of the other side surface of the side plate-shaped connection terminal 2210.
Thus, the side T-shaped connection terminal 2220 and the first heat sink LH1 may be coupled to the other side surface of the side plate-shaped connection terminal 2210, i.e., the same surface.
In addition, the first heat sink LH1 and the side T-shaped connection terminal 2220 may be coupled to the side plate-shaped connection terminal 2210 by fixing bolts, respectively.
The side T-shaped connection terminal 2220 includes a side horizontal portion 2221 and a side vertical portion 2222. The side horizontal portion 2221 is coupled to a side plate terminal 2210, and the side vertical portion 2222 extends in a direction orthogonal to the side horizontal portion 2221.
In addition, a second heat sink LH2 is coupled to one side surface of the side vertical portion 2222.
Thus, since the two heat sinks are coupled to the side terminal structure 2200, the effect of suppressing the temperature increase can be improved, and the performance of the circuit breaker can be improved.
First heat sink LH1 and second heat sink LH2 may be disposed orthogonal to each other with respect to the respective mounting directions.
Further, the side plate terminal 2210 may be formed with an insulating distance holder 2211. Further, the insulation distance from the front of the fixing member B is made longer by the insulation distance holding portion 2211. That is, the case where the insulation distance holder 2211 is formed secures the insulation distance D2 between the fixing member B and the side T-shaped wire terminal 2220 to be longer and secures the insulation distance D3 between the fixing member B and the side plate-shaped wire terminal 2210 to be longer than the insulation distance D1 in the case where the insulation distance holder 2211 is not formed.
In addition, the insulation distance maintaining portion 2211 may be formed in various shapes including a hole.
Thus, the terminal structure 2200 according to the embodiment of the present invention can be realized more stably.
Fig. 5 is a structural view schematically showing a central terminal structure among the terminal structures shown in fig. 2.
The central terminal structure 2100 includes a central plate-shaped terminal 2110 and a central T-shaped terminal 2120.
The central T-shaped terminal 2120 is generally "T" shaped.
The central terminal structure 2100 includes a central plate-shaped terminal 2110 and a central T-shaped terminal 2120. A central T-shaped terminal 2120 is coupled to one surface of the central plate-shaped terminal 2110, and the central plate-shaped terminal 2110 is coupled to a central portion of the circuit breaker 1000.
The central plate-shaped connection terminal 2110 is formed in a plate shape. A central T-shaped terminal 2120 is connected to the other side of the central plate-shaped terminal 2110 of the circuit breaker 1000.
The central T-shaped wire connection 2120 includes a central horizontal portion 2121 and a central vertical portion 2122. The central horizontal portion 2121 is coupled to the central plate-like connection terminal 2110, and the central vertical portion 2122 extends in a direction orthogonal to the central horizontal portion 2121.
In addition, a first central heat sink CH1 is coupled to one side surface of the central vertical portion 2122, and a second central heat sink CH2 is coupled to the other side surface.
That is, the first and second central heat radiating members CH1 and CH2 are combined with the central vertical portion 2122 by fixing bolts.
Thus, since the two heat sinks are coupled to the central terminal assembly 2100, the effect of suppressing the temperature rise can be improved, and the performance of the circuit breaker can be improved.
In addition, as shown in fig. 1, when the terminal assembly 2000 according to an embodiment of the present invention is mounted to the circuit breaker 1000, the side terminal assemblies 2200 that are symmetrical to each other may be located on both sides of the central terminal assembly 2100, and the second heat sink LH2 may be mounted to the side T-shaped terminals 2220 toward the central terminal assembly 2100, respectively.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above description of an embodiment is intended in all respects to be illustrative and not restrictive.
