Description

Vertical shunt type plug safe separating socket {vertical shunt type plug safe paring socket}

The present invention relates to a vertical shunt type plug safety disconnect outlet, and more specifically, to a vertical shunt type plug safety disconnect outlet with a simplified configuration and improved safety when generating heat.

Generally, an outlet is equipped to insert a power plug provided at the end of a cord of various electrical appliances. These outlets are connected to indoor electrical wiring and are installed on walls or floors. Accordingly, when the power plug is connected to the outlet, power is supplied to the electric appliance through a cord.

Here, the outlet is provided with a ground terminal on one side connected to an external ground plane, and the power plug is provided with a ground terminal connected to the ground terminal. Through this, when the ground portion of the power plug is interconnected to the ground terminal portion of the outlet, even if an abnormal current occurs in the indoor wiring, damage and malfunction of the electrical appliance to which the outlet is connected can be prevented by being grounded through the ground terminal portion.

Additionally, the outlet is provided with a latching bar that is electrically connected to the ground terminal portion, and a pair of ground lines is electrically connected to the ground terminal portion as it contacts the latching bar. At this time, each of the ground lines is clamped and fixed between the head portion of the extension screw member and the locking bar as the extension screw member penetrating the locking bar is screwed with the end portion of the ground line peeled off.

However, conventional outlets do not have a separate device to detect and automatically block the flow of current even if high heat is generated inside the outlet case due to an internal defect or an external fire, which can lead to secondary safety accidents. There was a serious problem.

In order to solve the above problems, the present invention aims to provide a vertical shunt type plug safety disconnect outlet with a simplified configuration and improved safety when generating heat.

In order to solve the above problem, the present invention includes a housing portion formed by electrically dividing a pair of mounting spaces formed through a power insertion hole through which a power supply side connection line is inserted on a lower surface of one side in the longitudinal direction; A terminal body provided on one side of the mounting space and electrically connected to the power connection line, and a plug connection portion extending from the terminal body toward the other side of the mounting space and forming a hollow portion into which a power plug is selectively inserted and electrically connected. A power terminal unit made of an electric current-conducting material and provided in pairs; a connection supporter provided on one side of the mounting space in the longitudinal direction and providing a pressing force so that the power-side connection line is supported in contact with the terminal body; and a shunt bar provided on the lower side of the hollow portion, elastically supported upward and restrained downward by being engaged with a slider, and extending laterally outside the outer periphery of the upper end of the shunt bar when the ambient temperature of the housing portion rises above a preset safe temperature. When the shunt bar elastically presses the power plug upward, it presses the slider so that it separates from the hollow portion and blocks the current, and includes a modular blocking portion including a temperature sensing blocking portion that is thermally deformed and expanded to separate it from the shunt bar. Provides a vertical shunt type plug safety disconnect outlet.

Through the above solutions, the present invention provides the following effects.

Second, as the temperature sensing cut-off part maintains its expanded state above the preset temperature, the slider is separated from the shunt bar, so the upward position of the shunt bar is maintained through the elastic recovery force of the elastic means until it is cooled to the safe temperature range, thereby maintaining the power plug and power supply. Since the terminals are spaced apart, safety against secondary accidents can be further improved.

Third, since the modular cut-off unit is mounted inside the case and is provided as a single assembly, the mold of the housing part is simplified and the defect rate is reduced. Not only is it easy to assemble, but the operation reliability is improved through accurate connection between parts, and only the modular cut-off part is used. Since it can be separated and replaced or reassembled after repair, maintainability can be significantly improved.

The coupling fixing groove 53 may be formed with an inner contour that corresponds to or is smaller than the outer contour of the body (PA) of the power plug, and at least both sides that are symmetrical are partially aligned with the outer surface of the body (PA) of the power plug. As they are combined, movement or arbitrary separation of the power plugs (P1, P2) can be prevented.

It is preferable that a power terminal hole 51 is formed on the bottom of the coupling fixing groove 53 so that the power plugs P1 and P2 can be inserted into electrical contact with the plug connection part 32, which will be described later. In addition, a pair of ground terminal holes 52 through which the upper end of the ground member 60 penetrates may be formed on the bottom surface of the coupling fixing groove 53 and spaced apart from the power terminal hole 51. The power terminal hole 51 is preferably aligned at a position corresponding to the upper and lower sides of the hollow portion 34, which will be described later.

The power terminal units 30 are arranged along the longitudinal direction of each mounting space 12, and are preferably provided in pairs symmetrically. The power terminal portion 30 is made of an electrically conductive material such as conductive metal such as brass, and preferably includes a terminal body 31 and the plug connection portion 32.

The terminal body 31 is provided on one side of the mounting space 12 and is electrically connected to the power supply side connection line 1a, and preferably includes an upper surface portion 31a and a contact surface portion 31b. The upper surface portion 31a is provided in a flat shape facing the bottom surface of one side of the mounting space 12 so as to cover the upper part of one side of the mounting space 12, and the contact surface portion 31b is the upper surface portion 31a. ) is preferably bent downward and extended from one end.

At this time, the contact surface portion 31b is preferably extended to correspond to the outer inner surface in the width direction of each mounting space 12 where the power insertion hole 11 is formed. Therefore, when the power supply side connection line (1a) is inserted into the power insertion hole (11), its end comes into contact with the contact surface portion (31b) and is electrically connected.

In addition, the plug connection portion 32 extends integrally from the terminal body 31 toward the other side in the longitudinal direction of the mounting space 12, and the power plugs P1 and P2 are selectively inserted and electrically connected. It is preferable that the hollow portion 34 is formed.

It can be electrically connected to the power supply side connection line (1a) via the body 31 and receive electricity.

At this time, the mounting opening 14 is formed through the other side of each mounting space 12 corresponding to the lower side of the hollow portion 34, and the modular blocking portion 80 is formed in the mounting opening 14. Combination is preferred.

Referring to Figures 3 and 4, the connection support parts 20 are provided in at least one pair, and are preferably provided on one side of each mounting space 12 where the power insertion hole 11 is formed. The connection support part 20 preferably includes an elastic piece 27 and a puller 28.

The elastic pieces 27 are preferably provided corresponding to each of the power insertion holes 11, and are spaced apart on both sides corresponding to the front-back direction of the housing portion 10 within one side of each mounting space 12. It is desirable to have them as a pair. And, when the power connection line 1a is introduced into the mounting space 12 through the power insertion hole 11, it is pressed toward the contact surface portion 31b through the elastic piece 27.

Moreover, referring to FIG. 4, as the elastic piece 27 is bent multiple times, the power supply side connection line 1a and the contact surface portion 31b can be stably pressed and contacted. At this time, it is preferable that the distal end of the elastic piece 27 in contact with the power connection line 1a is bent upwardly in accordance with the insertion direction of the power connection line 1a. Therefore, even if the power connection line 1a is pulled outward, it can be prevented from being unnecessarily separated from the outlet 100 by being engaged with the distal end of the elastic piece 27.

This elastic piece 27 may be formed of a metal material having a certain elasticity and may be manufactured using a stainless steel thin plate or the like. Through this, while providing a pressing force so that the power supply side connection line 1a comes into contact with the contact surface portion 31b and is electrically connected, it can be elastically deformed by the pressing force applied when pressing the puller 28, which will be described later. there is.

The puller 28 is inserted through the puller insertion hole 11a formed through a pair of power insertion holes 11, and the power connection line 1a is restrained by the elasticity of the elastic piece 27. The elastic piece 27 is pressed so that the state is selectively released. That is, when the puller 28 is pressed toward the upper side of the mounting space 12 in order to separate the power side connection line 1a from the outlet 100, the elastic piece ( The distal end of 27) is elastically deformed to one side of the mounting space 12. Through this, the distal end of the elastic piece 27 can be separated from the power connection line 1a and the restraint state can be released.

At this time, when the external force pressing the puller 28 upward is released, the puller 28 is pressed downward by the elastic restoring force of the elastic piece 27, and the puller 28 automatically returns to the initial position. It can be. Accordingly, the distal end of the elastic piece 27 is adjacent to and contacts the power supply side connection line 1a and is engaged and fixed, and the contact surface portion 31b and the power supply connection line 1a can be stably contacted. And, when the power supply side connection line (1a) is in contact with the contact surface portion (31b), it is electrically connected to the power terminal portion (30) and the power plugs (P1, P2) that selectively contact the power terminal portion (30). You can.

Meanwhile, referring to Figure 5, the modular blocking portion 80 is provided to be coupled to the mounting opening 14, and includes a shunt case 81, a shunt bar 87, a shunt cover 83, and a slider ( 85) is preferably included. The modular blocking portion 80 may be provided as a pair to be respectively coupled to the mounting openings 14 formed as a pair in the housing portion 10, and in some cases, one of the pair of mounting openings 14 may be used. It may be provided in . At this time, the modular blocking units 80 are provided in pairs, and the current in the outlet 100 can be blocked as long as at least one is operated through an operation described later.

The shunt case 81 has a storage space formed therein, and the shunt bar 87 is stored in the storage space. It is preferable that elastic means 82 is provided at the lower part of the shunt case 81 to elastically support the shunt bar 87 upward. Additionally, a fixing protrusion (81a) may protrude from the bottom surface of the shunt case (81) so that the position of the elastic means (82) is aligned.

The shunt bar 87 extends in the vertical direction to be able to be raised and lowered in the storage space, and is elastically supported upward through the elastic means 82 provided at the lower part. The shunt bar 87 is preferably aligned concentrically with the hollow portion 34. It is preferable that a restraining groove (87a) is formed radially inwardly recessed on one side of the outer circumference of the upper end of the shunt bar (87).

The shunt cover 83 is coupled to the upper end of the shunt case 81, and a through hole 84 through which the upper end of the shunt bar 87 protrudes is preferably formed. In addition, it is preferable that the temperature sensing blocking portions 40 are fixed in pairs on both sides of the through hole 84. At this time, it is preferable that a support portion 84a protruding to a predetermined thickness is formed along the outer edge of the through hole 84 to vertically support the shunt bar 87. Through this, since the shunt bar 87 is prevented from tilting during the lifting operation, the position can be aligned so that the lower ends of the power plugs (P1, P2) and the upper end of the shunt bar 87 always face each other.

In addition, a fixing groove (83a) in which the temperature sensing blocking unit 40 is fixed and a slide groove (83b) in which the slider 85 moves can be formed on both sides and one side of the outer edge of the through hole 84. . Through this, the fixing groove (83a) and the slide groove (83b) can be formed in a substantially 'ㄷ' shape on the upper surface of the shunt cover (83).

The slider 85 is preferably formed to extend in the front-back direction of the shunt cover 83 so as to move along the slide groove 83b. It is preferable that the slider 85 has a restraining protrusion 85a that is selectively inserted into the restraining groove 87a and protrudes toward the shunt bar 87. Also, it is preferable that at least one elastic spring 86 is provided on the opposite side of the restraining protrusion 85a.

In detail, the elastic spring 86 is provided between the other side of the slider 85 and the inner surface of the slide groove 83b. Accordingly, the slider 85 is elastically supported toward the shunt bar 87 through the elastic spring 86, and through this, the restraining protrusion 85a is selectively inserted into the restraining groove 87a to be engaged and fixed. Can be elastically supported.

At this time, the elastic means 82 may be formed to have an elastic recovery force greater than the force with which the body portion PA of the power plug is coupled to the coupling fixing groove portion 53. Accordingly, when the shunt bar 87 is restrained downward through the slider 85, the power plugs P1 and P2 are inserted into the hollow portion 34 and power can be applied. On the other hand, when the slider 85 is separated from the shunt bar 87, the power plugs (P1, P2) are struck by the shunt bar 87, which moves upward through the elastic restoring force of the elastic means 82. is spaced apart from the hollow portion 34, and the body portion (PA) of the power plug can be separated from the coupling fixing groove portion 53.

The shunt case 81, the shunt bar 87, the shunt cover 83, and the slider 85 are preferably made of an electrically insulating material such as synthetic resin. Accordingly, safety can be significantly improved because electric leakage to the modular blocking unit 80 is substantially blocked when the shunt bar 87 is in contact with the lower ends of the power plugs P1 and P2.

In addition, the mounting opening 14 is formed through a cross-sectional area of the modular blocking portion 80, and the mounting opening 14 is provided in at least one of the shunt case 81 and the shunt cover 83. A coupling protrusion 83c may be protruded to be coupled to the rim through a coupling means.

The temperature sensing blocking portion 40 is disposed to extend laterally outside the outer periphery of the upper end of the shunt bar 87, and is preferably provided in a pair. In detail, the temperature sensing blocking portion 40 may be symmetrically provided in the pair of restraining grooves 87a formed on the outer outer side of the through hole and includes a fixed end 41 and a free end 42. The fixed end 41 is fixed to the shunt cover 83, and the free end 42 extends from the fixed end 41 toward the slider 85 and is preferably bent to be rounded and convex upward. . The free end 42 is in contact with the slider 85, and may preferably be caught by a step formed on the upper side of the restraining protrusion 85a.

As such, in the present invention, each component of the modular blocking unit 80 is first coupled to the shunt case 81 to form one assembly and then mounted in the mounting space 12. Therefore, when the housing part 10 itself is injection-processed, the mold is simplified, and the defect rate can be significantly reduced and productivity can be improved.

In addition, each component is compactly coupled to each protrusion or groove formed on the shunt case 81 and the shunt cover 83, and is then provided in the form of a relatively large assembly, so that it is provided in the form of a relatively large assembly corresponding to the lower side of the hollow portion 34. It is coupled to the mounting space (12). Accordingly, the difficulty of assembling the components can be lowered while the driving reliability through assembly accuracy can be significantly improved. Furthermore, depending on the installation environment and purpose of the outlet 100, only the modular blocking unit 80 can be separated, replaced with parts, and reassembled for use, thereby significantly improving maintainability.

Meanwhile, the temperature sensing blocking portion 40 is preferably made of bimetal that is bent roundly and has a concave lower surface, especially the lower surface of the free end 42, which has a higher coefficient of thermal expansion than the upper surface. For example, the temperature sensing blocking unit 40 may be provided with a plate made of copper disposed on the lower surface and a plate made of iron, which has a lower thermal expansion coefficient than that of copper, disposed on the upper surface, joined to each other, and bent convexly toward the outer surface.

Accordingly, when heat above the preset safe temperature is applied to the temperature sensing blocking unit 40, the lower surface made of copper expands to a higher thermal expansion coefficient. At this time, since the fixed end 41 is fixed to the shunt cover 83, the free end 42 may expand in the longitudinal direction of the temperature sensing blocking portion 40.

At this time, the ambient temperature of the housing unit 10 is preferably understood as a concept encompassing the air temperature inside the housing unit 10 and the temperature of each component disposed within the housing unit 10. Here, the safe temperature can be set at 70 to 100°C, and most preferably at 80°C.

In detail, referring to FIG. 6, when the surrounding temperature of the housing portion 10 is below the safe temperature, the free end 42 of the temperature sensing blocking portion 40 is maintained in a rounded and curved shape. Accordingly, the slider 85 is elastically pressed toward the shunt bar 87 by the elastic restoring force of the elastic spring 86, and the restraining protrusion 85a is engaged with the restraining groove 87a of the shunt bar 87. It is fixed. Accordingly, the shunt bar 87 is maintained in a downwardly restrained state.

Through this, the power plugs (P1, P2) are inserted into the hollow portion 34 and come into contact with the power terminal portion 30, and the power supply side connection line (1a), the power terminal portion 30, and the power plug are connected to each other. Current flows through (P1, P2). At this time, the elastic means 82 is compressed between the lower surface of the shunt bar 87 and the bottom surface of the shunt case 81.

And, referring to FIG. 7, when the surrounding temperature of the housing portion 10 rises above the safe temperature, the free end 42 of the temperature sensing blocking portion 40 expands and undergoes thermal deformation.

In detail, the lower surface of the temperature sensing blocking portion 40 is formed with a higher thermal expansion coefficient, so when heat above the safe temperature is transmitted, the roundly curved free end 42 is thermally deformed to unfold and substantially extends in length. You can. At this time, since the fixed end 41 is fixed to the shunt cover 83, the free end 42 is extended toward the end, and the slider 85 is pressed and moved.

Here, the elastic restoring force of the elastic spring 86 is formed as a force smaller than the force pushing the slider 85 due to thermal expansion of the temperature sensing blocking portion 40. Accordingly, the slider 85 is pressed so that the restraining protrusion 85a can be separated from the restraining groove 87a.

When the restraining protrusion (85a) is separated from the restraining groove (87a), the restraining force applied to the shunt bar (87) is released, and the shunt bar (87) is released by the elastic restoring force of the compressed elastic means (82). It moves rapidly upward. Accordingly, the upper end of the shunt bar 87 is drawn upward into the hollow part 34 and the power plugs P1 and P2 in contact with the hollow part 34 are pushed upward with strong force. Through this, the power plugs (P1, P2) are separated from the hollow portion 34, so the current can be automatically blocked.

That is, the present invention operates to block current as the power plugs (P1, P2) are separated from the hollow portion (34) and the electrical connection state is released through the operation of the modular blocking unit (80). At this time, when the slider 85 is pressed and moved along the slide groove 83b through the temperature sensing blocking unit 40, the elastic spring 86 may be compressed and deformed.

Here, when the power plugs (P1, P2) are separated from the hollow portion (34) through the operation of the modular blocking portion (80), the body portion (PA) of the power plug is connected to the coupling fixing groove portion (53). It protrudes outward. Therefore, the user can visually check the body portion (PA) of the power plug protruding to the outside of the outlet 100, immediately determine that the current is blocked, and then proceed with subsequent processing. Since the blocking state can be maintained, safety can be significantly improved.

At this time, when the surrounding temperature of the housing portion 10 is maintained above the safe temperature, the temperature sensing blocking portion 40 is maintained in an expanded and thermally deformed state. Accordingly, the slider 85 is pressurized and supported so as to be spaced apart from the shunt bar 87, and even if the power plugs P1 and P2 are inserted into the hollow portion 34, the slider 85 is supported by the elastic recovery force of the elastic means 82. It can be released again by being pressed against the shunt bar 87.

In this way, according to the present invention, the temperature sensing blocking portion 40 is made of a bimetal that maintains an expanded state above a preset temperature, so that the slider 85 can be pressurized and supported until cooled to a preset safe temperature range. Accordingly, safety can be further improved because unnecessary restraint of the shunt bar 87 due to arbitrary return of the slider 85 is limited.

And, when the surrounding temperature of the housing part 10 falls again below the safe temperature, the temperature sensing blocking part 40 is restored to its original rounded and curved shape. Accordingly, the slider 85 can be elastically pressed toward the shunt bar 87 through the elastic restoring force of the elastic spring 86 compressed between the slider 85 and the slide groove 83b.

At this time, when the power plugs (P1, P2) are reinserted into the hollow portion 34, the shunt bar 87 is pressed downward. Then, when the shunt bar 87 is pressed and the positions of the restraining groove 87a and the restraining protrusion 85a are aligned in the horizontal direction, the restraining protrusion 85a is compressed through the elastic pressure of the elastic spring 86. can be engaged and fixed while being inserted into the restraining groove (87a). Through this, the shunt bar 87 is restrained downward and the power plugs (P1, P2) and the power terminal portion 30 come into contact again, allowing current to flow.

That is, when the ambient temperature of the housing part 10 rises above the safe temperature, the modular blocking unit 80 connects the power plugs (P1, P2) through expansion and thermal deformation of the temperature sensing blocking unit 40. ) is preferably understood as a device that operates to separate from the hollow portion 34 and blocks the flow of current. In other words, it is preferable to understand that the modular blocking unit 80 of the present invention does not function to block current flow when a simple overcurrent occurs, but rather functions to block current flow according to the increase in the ambient temperature of the housing unit 10. .

Therefore, secondary safety accidents can be prevented by stably blocking the current flow of the product even when the ambient temperature of the housing part 10 increases due to external factors such as fire as well as heat generation due to defective components.

At this time, the restraining grooves 87a are recessed at predetermined intervals on one side of the outer circumference of the shunt bar 87. In addition, a rotational restraint surface portion 88 whose outer surface is slidably supported along the inner surface of the shunt case 81 is provided at the lower end of the shunt bar 87 so that the restraint groove 87a and the restraint protrusion 85a are opposed to each other. It is desirable that is formed.

That is, as the restraining groove 87a is formed to a minimum on the outer periphery of the shunt bar 87, durability can be significantly improved by preventing damage or fracture due to external force. In addition, when the shunt bar 87 moves up and down inside the shunt case 81, it can be prevented from being rotated unnecessarily through the rotation restraint surface portion 88. Therefore, operational reliability can be significantly improved as the restraining groove 87a and the restraining protrusion 85a are always aligned to face each other. Of course, in some cases, the restraining groove may be recessed into a ring shape along the circumferential direction of the shunt bar 87, and such modifications are within the scope of the present invention.

At this time, terms such as “include,” “comprise,” “equip,” or “have,” as used above, mean that the corresponding component may be present, unless specifically stated to the contrary. Rather than excluding a component, it should be interpreted as allowing additional inclusion of other components. All terms, including technical or scientific terms, unless otherwise defined, have the same meaning as generally understood by a person of ordinary skill in the technical field to which the present invention pertains. Commonly used terms, such as terms defined in a dictionary, should be interpreted as consistent with the contextual meaning of the related technology, and should not be interpreted in an idealized or overly formal sense unless explicitly defined in the present invention.

As explained above, the present invention is not limited to the above-described embodiments, and modifications and implementations can be made by those skilled in the art without departing from the scope of the claims of the present invention. And these modifications fall within the scope of the present invention.

Claims (5)

A housing portion formed by electrically dividing a pair of mounting spaces formed through a power insertion hole through which a power supply side connection line is inserted on a lower surface of one side in the longitudinal direction;
A terminal body provided on one side of the mounting space and electrically connected to the power connection line, and a plug connection portion extending from the terminal body toward the other side of the mounting space and forming a hollow portion into which a power plug is selectively inserted and electrically connected. A power terminal unit made of an electric current-conducting material and provided in pairs;
a connection supporter provided on one side of the mounting space in the longitudinal direction and providing a pressing force so that the power-side connection line is supported in contact with the terminal body; and
A shunt bar provided on the lower side of the hollow portion, elastically supported upward and restrained downward by being engaged with a slider, and a shunt bar extending laterally outside the outer periphery of the upper end of the shunt bar when the ambient temperature of the housing portion rises above the preset safe temperature. The shunt bar elastically presses the power plug upward to separate it from the hollow portion and presses the slider to block current, comprising a modular blocking portion including a temperature sensing blocking portion that is thermally deformed and expanded to separate it from the shunt bar; ,
The modular blocking portions are provided in pairs to be coupled to mounting openings formed through the other side of each mounting space corresponding to the lower portion of the hollow portion,
A shunt case made of insulating material provided with elastic means for elastically supporting the shunt bar upward in a storage space formed therein,
A shunt cover that is coupled to the upper end of the shunt case and has a through hole through which the upper end of the shunt bar protrudes, and in which the temperature sensing blocking portion is fixed in pairs on both sides of the through hole;
A vertical shunt-type plug safety disconnect outlet, characterized in that it includes the slider that moves along a slide groove formed on the upper surface of the shunt cover and has a constraining protrusion that is selectively inserted into a constraining groove formed on the top of the shunt bar. delete According to claim 1,
The temperature sensing blocking unit
A fixed end fixed to the shunt cover,
It extends from the fixed end to the slider side and is curved to be round and convex upward, and is bent round to press the slider so that the restraining protrusion is separated from the restraining groove when the housing portion rises above the safe temperature to have a concave bottom surface. A vertical shunt type plug safety disconnect outlet characterized by including a free end formed with a higher coefficient of thermal expansion than the upper surface. According to claim 1,
A vertical shunt-type plug safety disconnect outlet, characterized in that an elastic spring is provided between the other side of the slider and the inner surface of the slide groove to elastically support the slider toward the shunt bar so that the restraining protrusion is inserted into the restraining groove and locked into place. . According to claim 1,
The restraining groove is formed to be recessed in a radial inward direction on one side of the outer circumference of the shunt bar,
A vertical shunt-type plug safety disconnect outlet, characterized in that a rotational restraint surface portion whose outer surface is slidably supported along the inner surface of the shunt case is formed at the lower end of the shunt bar so that the restraint groove and the restraint protrusion are opposed to each other.
