I can.

Further, the second contact extension 20f is integrally bent and extended from the end of the first contact extension 20e, but is formed to be inclined upward in a direction closer to the outer wall of the terminal body 331 toward the end. This is desirable. At this time, a portion connected to the second contact extension 20f and the first contact extension 20e may be bent round so that the extension direction of the second contact extension 20f is changed, and the first The contact extension 20e and the second contact extension 20f may be spaced apart at predetermined intervals and disposed to face each other.

On the other hand, it is preferable that a puller insertion hole 311a is formed vertically through the housing 310 at a position spaced apart from each of the power insertion holes 311 on one side of each of the mounting spaces 312. In addition, the receptacle 400 is slide inserted into the puller insertion hole 311a, and the upper end thereof is disposed to face the lower portion of the second contact extension 20f of the power connector 20 so that the power connector 20 It is preferable to include a puller part 21 for selectively pressing so as to be elastically deformed.

Here, it is preferable that the puller part 21 is slide-inserted into the puller insertion hole 311a, and the upper end thereof is disposed in opposing contact with the power connection part 20. In addition, a plurality of the puller parts 21 are preferably provided, but are respectively inserted into each of the puller insertion holes 311a. In this case, the puller part 21 may slide in a vertical direction along the inner surface of the puller insertion hole 311a.

In addition, a pressure support piece 21a may protrude upward from an upper end of the puller part 21, and the pressure support piece 21a is preferably disposed facing the lower side of the power connection part 20. Here, the puller insertion hole 311a is disposed under the mounting space 312, and the power insertion hole 311 is away from the puller insertion hole 311a in the width direction of the housing 310 Can be arranged in any direction. Through this, when the power-side connection line 1a is inserted through the power insertion hole 311, the end portion 1c of the power-side connection line 1a is disposed adjacent to the power terminal 330 to be electrically connected. The puller part 21 may be disposed facing the lower side of the power connection part 20.

And, the pressing support piece (21a) may be disposed facing the contact portion (20d), when the puller portion (21) is pressed, the pressing support piece (21a) is in close contact with the contact portion (20d) Can be delivered. Here, when the puller part 21 is pressurized through the opening side of the puller insertion hole 311a, it slides toward an upper side, that is, toward the power connector 20 side. At this time, the contact portion (20d) may be pressed toward the upper side of the pressing support piece (21a) is in close contact, and the power connection portion (20) is the puller portion (21) with the upper side supported by the bending support portion. It can be elastically deformed by the pressing force of

Moreover, a pressure inclined surface may be formed at an end of the pressure support piece 21a, and the pressure inclined surface may be formed to be inclined toward the upper side, so that the contact portion 20d may be pressed in contact with the pressure inclined surface. In addition, the inclination angle of the pressure inclined surface may be set to correspond to the inclination angle of the second extended contact portion 20d disposed to face each other. Through this, the contact part 20d is pressed in a state in surface contact with the pressing slope during the pressing operation of the puller part 21, so that the pressing force is accurately transmitted and the direction in which the product is moved through elastic deformation can be guided. Driving reliability can be improved.

In addition, when the puller part 21 is continuously pressed upwardly, the elastic parts 20b and 20c are elastically deformed, and the contact part 20d is elastically moved upward. In addition, a portion connected to the second contact extension 20f and the first contact extension 20e is elastically deformed so that the second contact extension 20f is adjacent to the first contact extension 20e. It moves resiliently. For this reason, the distance between the second contact extension portion 20f and the power terminal portions 330 that face each other by the pressing force of the puller portion 21 may be increased.

At this time, when the power-side connection line (1a) is inserted into the power insertion hole 311, the end portion (1c) of the power-side connection line (1a) is disposed between the contact portion (20d) and the power terminal (330). I can. Here, the end portion 1c of the power-side connection line 1a may be electrically connected to each other when in contact with the power terminal portion 330 in a state where the covering is removed.

In addition, when the external force for pressing and manipulating the puller part 21 with the end part 1c of the power-side connection line 1a disposed between the contact part 20d and the power terminal part 330 is released, each of the The puller part 21 slides by the elastic restoring force of the power connection part 20. At this time, as the power connection part 20 is resiliently restored, the distance between the contact part 20d and the power terminal part 330 facing each other becomes close, and the end part 1c of the power-side connection line 1a Is elastically pressed by the contact portion 20d. Accordingly, the end portion 1c of the power-side connection line 1a may be elastically pressed between the power terminal portion 330 and the contact portion 20d to be engaged.

Through this, since the end portion 1c of the power-side connection line 1a is pressed by the contact portion 20d and is in close contact with the power terminal portion 330, a power plug that is selectively electrically connected to the power terminal portion 330 It can be electrically connected to (P1, P2).

In addition, the puller part 21 may be moved to its original position by the elastic restoration force of the power connection part 20. Of course, the power-side connection line 1a may be separated from the power insertion hole 311 after releasing the elastically pressurized state by the contact part 20d by pressing the puller part 21. That is, the power-side connection line 1a may be fixed and separated from the power connection part 20 only by pressing the puller part 21.

In this way, after the puller part 21 is pressed, each power-side connection line 1a is inserted and the pressurized state of the puller part 21 is released. The end portion 1c of (1a) is elastically pressed and fixed by the power connector 20. Accordingly, the end portion 1c of each power-side connection line 1a, which is not covered, is inserted into the inner side of each power insertion hole 311, and then is elastically engaged and fixed by the power connection unit 20. . Therefore, unlike the prior art in which the end portion 1c of each of the power-side connection lines 1a is exposed to the outside, various safety accidents such as electric shock due to contact with the operator during installation work are prevented in advance, so safety can be significantly improved. I can.

On the other hand, the power terminal portion 330 is disposed on the upper side of each of the power connection portion 20, and preferably includes a pair of terminal bodies 331 electrically connected to the power-side connection line (1a). Here, it is preferable that the power terminal part 330 is made of a conductive material such as a conductive metal including copper. At this time, the inner surface of the outer wall portion of the stepped body 331 is selectively electrically connected to the end portion 1c of the power-side connection line 1a, and the lower surface of the upper portion of the terminal body 331 is the power connection unit 20 ) Can be supported in contact with the top.

In addition, the power terminal portion 330 extends integrally in a pair from each of the terminal body paths 331 toward the other side of each of the mounting spaces 312, but powers the hollow portion 34 formed on the opposite inner surface side. It is preferable to include a pair of plug connection portions 332 and 333 to which the plugs P1 and P2 are selectively inserted and electrically connected.

At this time, the housing part 310 has an inner diameter corresponding to the outer diameter of the power plugs P1 and P2 so as to guide the ends of the power plugs P1 and P2 from the bottom surface of the center side of the mounting space 312. The ring-shaped protrusion 315 may protrude upwardly.

Here, each of the plug connection portions 332 and 333 are integrally extended from the terminal body 331, and a region corresponding to the gap between the front end of the ring-shaped protrusion 315 at the rear end of the terminal body 331 is linear Can be extended to

At the same time, each of the plug connection portions 332 and 333 passes through an area corresponding to the upper side of the ring-shaped protrusion 315 from the end of the area extending in a straight line, and is further extended, but the area corresponding to the upper side of the ring-shaped protrusion 315 is The power plugs P1 and P2 may be convexly wrapped outward in the width direction so as to surround the outer surfaces of the power plugs P1 and P2. In this case, the hollow portion 34 may be formed so that the power plugs P1 and P2 are inserted into the inner surfaces of each of the plug connection portions 332 and 333 formed to be rounded. In addition, the lower surfaces of the plug connection portions 332 and 333 formed to be round may be seated and supported on the upper surface of the ring-shaped protrusion 315.

Here, when the power plugs P1 and P2 are inserted into the hollow part 34 to be electrically connected to the inner surfaces of each of the plug connection parts 332 and 333, the power plugs P1 and P2 are connected to the plug connection part ( Power may be supplied by being electrically connected to the power-side connection line 1a via 332 and 333 and the terminal body 331.

On the other hand, it is preferable that the cover part 50 is disposed face-to-face to cover the upper side of the housing part 310, and the lower part is in close contact with the upper end part of the housing part 310. In detail, a mating fixing groove 53 into which the power plugs P1 and P2 are inserted is formed in the upper surface of the cover part 50. Here, the mating fixing groove 53 may be formed as an inner profile corresponding to the outer surface profile of the mating part PA of the power plug, and is arbitrarily separated as the mating part PA of the power plug is mated and inserted. Can be prevented.

At this time, a pair of power terminal holes 51 are formed through the bottom surface of the mating fixing groove 53 in the vertical direction so as to correspond to the position of the hollow part 34 formed between the plug connection parts 332 and 333. In addition, a pair of ground terminal holes 52 through which the upper end of the ground member 60 is disposed is formed on the bottom surface of the mold fixing groove 53 to be spaced apart from the power terminal hole 51.

Here, each power terminal hole 51 may be formed at a position corresponding to the upper side of the ring-shaped protrusion 315 and the hollow part 34. Accordingly, the power plugs P1 and P2 may be respectively inserted into the power terminal holes 51 to be connected to the plug connection portions 332 and 333.

At this time, when the mating part PA of the power plug is mated to the mating fixing groove 53, the power plugs P1 and P2 are inserted in the power terminal hole 51 in a vertical direction, so that the housing part 310 If the ambient temperature of) is less than a preset safety temperature, the power plugs P1 and P2 are electrically connected to the plug connectors 332 and 333, and when the ambient temperature of the housing 310 is higher than a preset safety temperature, the temperature Even when the plug connection parts 332 and 333 are expanded to both sides by the sensing blocking part 340 and a torsional force is applied by the load of the wire cable, the power plugs P1 and P2 vertically arranged are the plug connection parts 332 and 333 It can be stably separated from and the current flow can be blocked.

On the other hand, the temperature sensing cut-off part 340 has both fixed ends 341 and 342 fixed at the bottom of each of the plug connection parts 332 and 333, and a free end 343 is integrally formed between the fixed ends 341 and 342. It is provided to be inclined. At this time, it means that the free end 343 extends obliquely in any one direction of one side and the other side of the housing 310 toward the center of the width direction from each of the fixed ends 341 and 342, and is bent or rounded. It means to be provided in a V'or'U' shape.

In addition, when the ambient temperature of the housing part 310 rises above a preset safe temperature, the temperature sensing blocking part 340 expands to both sides based on the center of the free end 343 According to the deformation, when the fixed ends 341 and 342 are moved to both sides, the plug connection parts 332 and 333 are interlocked and deformed to both sides, so that the plug connection parts 332 and 333 are electrically cut off from the power plugs P1 and P2. One surface disposed to face one side of the space 12 is formed with a lower coefficient of thermal expansion than the other surface.

In this case, the ambient temperature of the housing unit 310 is preferably understood as a concept encompassing the air temperature inside the housing unit 310 and the temperature of each component disposed inside the housing unit 310.

For example, the temperature sensing blocking part 340, in particular, the free end 343 may be provided by having a flat plate made of copper disposed on the other side and a flat plate made of iron having a lower coefficient of thermal expansion than that of copper disposed on one side and bonding to each other have. Accordingly, when the ambient temperature of the housing part 310 rises above a preset safe temperature, the free end 343 is in the width direction while the fixed ends 341 and 342 are fixed to each of the fixing protrusions 335 and 336 to be described later. It can be expanded and thermally deformed on both sides.

At this time, the preset safety temperature may be set to 70 ~ 100 ℃, most preferably set to 80 ℃. That is, when the ambient temperature of the housing part 310 is not increased due to an overcurrent, but the free end 343 of the temperature sensing blocking part 340 is expanded and thermally deformed, each of the plug connection parts 332 and 333 are moved to both sides. It is deformed under pressure so that the plug connection portions 332 and 333 may be electrically cut off from the power plugs P1 and P2.

That is, when the ambient temperature of the housing part 310 rises above a preset safe temperature, the temperature sensing blocking part 340 interlocks and presses each of the plug connection parts 332 and 333 through the pressurization of the free end 343. It is a device that blocks current flow. In other words, when the ambient temperature of the housing unit 310 rises above a preset safe temperature, the current flow is blocked by the temperature sensing blocking unit 340, not a function of blocking current flow when an overcurrent occurs.

On the other hand, at the bottom of each of the plug connection portions 332 and 333, fixing protrusions 335 and 336 are integrally protruding downwardly with the hollow part 334 interposed therebetween, and the fixing ends 341 and 342 are It is preferable that the outer surface is wrapped and fitted.
