2 is a view for explaining a deformation area formed by a housing part and a support part of the explosion-proof terminal box according to an embodiment of the present invention.

The housing part 110 includes a body part 111 for providing the arrangement space S10 and a communication space for communicating the arrangement space S10 with the outside when the cover part 120 is in the open position And a main body connection part 112 (refer to FIG. 5) connected to the cover part 120 when the cover part 120 is in the closed position.

The housing part 110 may further include an intermediate part 113 connected to the body part 111 and mediating the body part 111 and the supporting part 130 with each other.

The main body connecting part 112 may extend from the inner surface of the main body 111. [

The main body connection part 112 may be formed with a body hole h10 (see FIG. 5) into which the first fastening means 210 can be inserted.

Here, the first fastening means 210 may be a bolt and / or a nut, but the present invention is not limited thereto. The first fastening means 210 may be variously modified at a level that is obvious to a person skilled in the art.

The body portion 111 and the body connection portion 112 may be integrally formed.

However, the present invention is not limited thereto, and the main body 111 and the main body coupling 112 may be connected to each other by welding.

In addition, the main body 111 and the intermediate portion 113 may be integrally formed.

However, the present invention is not limited thereto, and the main body 111 and the intermediate portion 113 may be connected to each other by welding.

The mediating part 113 may be connected to the side surface (one surface of the main body 111 in the rightward direction W3 or the leftward direction W4) of the main body 111. [

The intermediate portion 113 may be connected to the main body 111 so as to protrude from a part of the side surface of the main body 111.

For example, the intermediate portion 113 may be connected to a side surface of the main body 111 so as to be spaced apart from a side edge portion of the main body 111. Therefore, when the side surface of the main body 111 is deformed due to the explosion force when the explosion occurs in the accommodation space S100, excessive deformation of the side surface of the main body 111 can be prevented.

The first intermediate portion 113a may be connected to the upper side of the main body 111 and the second intermediate portion 113b may be connected to the lower side of the main body 111. [ When an explosion occurs in the accommodation space S100, the side surface of the main body 111 between the first and second intermediate portions 113a and 113b may be deformed. The first intermediate portion 113a is connected to the side edge of the main body 111 in the upward direction W1 and the second intermediate portion 113b is connected to the side surface of the main body 111 in the downward direction W2. The first intermediate portion 113a and the second intermediate portion 113b are connected to the side surface of the main body 111 more than the first intermediate portion 113a and the second intermediate portion 113b, When the explosion is generated in the accommodation space S100 because the area of the main body portion 111 between the main body portion 111 and the portion 113b is smaller, Can be prevented.

That is, the degree of deformation of the main body 111 can be adjusted according to the position where the first and second mediamines 113a and 113b are connected to the main body 111.

However, the present invention is not limited thereto, and the portion where the intermediate portion 113 is connected to the main body 111 can be variously modified at a level that is obvious to a person skilled in the art.

2, when the explosion is generated in the accommodation space S100 in a state where the cover portion 120 is in the open position, the housing portion 110 is deformed, The portion 110 may be at least partially spaced from the support 130 to absorb the impact by an explosion.

Specifically, the intermediate portion 113 may be coupled to the support portion 130 by the third fastening means 230. Therefore, the main body 111 can maintain a fixed position with respect to the support 130.

Here, the main body 111 and the support 130 may be spaced apart from each other.

For example, one side of the main body 111 in the backward direction W6 may be spaced apart from the support 130. [

Also, one surface of the main body 111 in the rightward direction W3 may be spaced apart from the support portion 130. [

Also, one surface of the main body 111 in the leftward direction W4 may be spaced apart from the support 130.

Therefore, when an explosion occurs in the accommodating space S100, the main body 111 may be deformed to absorb an impact depending on the explosion.

If the body portion 111 is connected to and / or fixed to the support portion 130, the degree of deformation of the body portion 111 may be smaller than that of the embodiment of the present invention. In this case, the impact caused by the explosion generated in the accommodation space S100 is transmitted to the first fastening means 210 in a different configuration, for example, so that the possibility that the other configuration is broken may be further increased.

Therefore, the explosion-proof terminal box 100 can effectively cope with an impact caused by the explosion by separating the body portion 111 from the support portion 130.

Here, the third fastening means 230 may be a bolt and / or a nut, but the present invention is not limited thereto, and the third fastening means 230 may be variously modified at a level that is obvious to a person skilled in the art.

A connection cover portion 122 which is coupled to the connection cover portion h20 and a complementary portion 123 which extends from the connection cover portion 122 around the cover hole h20 and which complements the connection cover portion 122 around the cover hole h20 ).

The main cover part 121 may provide a cover space S30 which is a predetermined space.

The main cover part 121 may be connected to the connection cover part 122 in a stepped manner.

Specifically, one surface of the main cover part 121 and one surface of the connection cover part 122 may have a non-uniform surface.

That is, one surface of the main cover portion 121 in the forward direction W5 may protrude in the forward direction W5 from the one surface of the connection cover portion 122 in the forward direction W5.

Thus, the space of the accommodation space S100 can be maximized.

The connection cover part 122 may be formed in a circumferential direction of the main cover part 121. [

A cover hole h20 into which the first fastening means 210 can be inserted may be formed in the connection cover portion 122. [

When the cover part 120 is in the closed position, one side of the connection cover part 122 may be in contact with one side of the main body connection part 112.

[ the cover portion 120 can be fixed to the body portion 111 so that the accommodation space S100 can be sealed from the outside.

The connection cover part 122 may be integrally formed with the main cover part 121.

However, the present invention is not limited thereto, and the connection cover part 122 may be connected to the main cover part 121.

For example, the connection cover portion 122 may be connected to the main cover portion 121 by welding.

The complementary part 123 may extend to protrude from the connection cover part 122.

Specifically, the complementary portion 123 may be formed to project from the one side of the connection cover portion 122 in the forward direction W5 in the forward direction W5.

The complementary part 123 may extend from the connection cover part 122 so as to surround the cover hole h20 formed with the connection cover part 122. [

More specifically, when the cover 120 is in the closed position and an explosion occurs in the receiving space S100, a large external force may be applied to the first fastening means 210. [ In this case, too much external force may be applied to the connection cover portion 122 connected to the first fastening means 210. The upper supplement 123-1, the lower supplement 123-2 and the connection supplement 123-3 can effectively prevent the connection cover 122 from being damaged by the external force .

Since the main cover portion 121 is connected to the connection cover portion 122 while providing the cover space S30, when the explosion occurs in the accommodation space S100, the main cover portion 121 may be vulnerable to an external force due to explosion have. As a result, the portion where the main cover portion 121 and the connection cover portion 122 are connected is damaged, so that the cover space S30 can communicate with the outside. To prevent this, the connection supplement unit 123-3 may reinforce a portion where the main cover unit 121 and the connection cover unit 122 are connected.

More specifically, the connection complement 123-3 may be connected to a side surface of the main cover 121 and a front surface of the connection cover 122 in the forward direction W5. One end of the connection complement 123-3 may be connected to the upper complement 123-1 and the other end of the connection complement 123-3 may be connected to the lower complement 123-2. Lt; / RTI > The connection complement 123-3 may be configured to connect an external force acting on the main cover part 121 to the upper complement part 123-1, the lower complement part 123-2, and the connection cover part 122 ). ≪ / RTI >

The moving implement 160 includes a reference part 161 connected to the housing part 110 and a moving part 162 connected to the reference part 161 so as to be movable with respect to the reference part 161, .

Specifically, the reference portion 161 may be coupled to the side surface of the main body 111. [ The moving unit 162 may be connected to the reference unit 161 and may be connected to the cover unit 120.

For example, the moving unit 162 may be connected to the reference unit 161 to be rotatable with respect to the reference unit 161.

However, the present invention is not limited to this, and the manner in which the moving unit 162 is connected to the reference unit 161 can be variously modified at a level that is obvious to a person skilled in the art.

For example, the moving unit 162 may be connected to the reference unit 161 to slide on the reference unit 161.

The moving part 162 may move the connection cover part 122 in order to reduce an external force applied to the first fastening part 210 when an explosion occurs in the accommodation space S100. As shown in FIG.

The complementary portion 123 includes a first complementary portion 123a extending from the connection cover portion 122 around the first cover hole h21 and a second complementary portion 123b extending from the connection cover portion h22 around the second cover hole h22. 122 and extending from the connection cover portion 122 around the third cover hole h23 and extending from the first complementary portion 123a to the first complementary portion 123a, And a third complementary part 123c spaced apart from the first complementary part 123a.

Here, the first complementary part 123a, the second complementary part 123b, and the third complementary part 123c may be classified in the same configuration depending on the position extending from the connection cover part 122 .

The moving part 162 is connected to the reference part 161 and includes a first moving part 162a and a second driving part 162b disposed between the first and second complement parts 123a and 123b, 123a and the third complementary part 123c.

Similarly, each of the one-side moving part 162a and the other side moving part 162b may be connected to the pillar part so as to be rotatable with respect to the reference part 161. [

One side of the one side moving part 162a may be connected while being in contact with one side of the connecting cover part 122 in the front direction W5.

One side of the other side movable part 162b may be connected while being in contact with one side of the connection cover part 122 in the forward direction W5.

Due to the configuration of the moving unit 162, the moving unit 162 can be connected to the connection cover unit 122 without being in conflict with the complementary unit 123.

More specifically, when an explosion occurs in the accommodation space S100, the reinforcing portion may be deformed due to an explosive force due to the explosion. If the moving part 162 is in contact with the reinforcing part, a large external force may be applied to the second fastening part 220 due to the deformation of the reinforcing part. Since the moving part 162 is spaced apart from the reinforcing part, it is possible to effectively prevent the second fastening device 220 from being damaged by the deformation of the reinforcing part.

If the second fastening means 220 is broken, the cover 120 may drop in the process of opening the cover 120 after the explosion occurs in the accommodating space S100. In this case, the portion for opening the cover portion 120 may be injured to a large extent.
