본원 고안은 소형 배선용 차단기, 누전차단기의 전선접속후 전원측과 부하측의 단자부 보호를 위하여 사용하는 단자 보호덮개에 관한 것이다.The present invention relates to a terminal protective cover used for protecting the terminal part of the power supply side and the load side after connecting a small circuit breaker and an earth leakage breaker.

종래에 있어서 소형배선용 차단기, 누전차단기는 배선이 끝난후 전원측, 부하측의 단자부를 보호해 주기위해 사용하는 단자 보호덮개를 취부하는 방법에 있어 제4도에서 보는 바와같이 전선 접속후 단자 보호덮개(11)를 복개하고 작은 나사(44)를 사용하여 차단기 본체(22)에 형성한 나사홈(33)에 죄어 주는 구조로서 드라이버등의 공구를 사용하는 번거로움과 많은 시간이 소요되는 불편함을 초래하였으며, 또한 단자부에 통전이 되고 있을 경우 드라이버등의 도체를 통해 감전사고의 위험을 내포하고 있는 결함이 있었던 것이다.Conventionally, a small circuit breaker and an earth leakage circuit breaker have a terminal protective cover after connecting the wires as shown in FIG. 4 in the method of attaching the terminal protective cover used to protect the terminal parts of the power supply side and the load side after the wiring is completed. ) Is screwed into the screw groove 33 formed in the circuit breaker main body 22 using a small screw 44, resulting in the inconvenience and time-consuming inconvenience of using a tool such as a screwdriver. In addition, if the terminal part is energized, there is a defect that implies the risk of electric shock through a conductor such as a driver.

본원 고안은 상기한 제결함을 감안하여 안출한 것으로 작은 나사나 드라이버등의 공구의 사용없이 원텃치의 간편한 조작으로 단자 보호덮개를 끼워 넣기만 하면 되는 구조로서 사용자의 편의와 안전성을 도모하기 위한 것이며 이를 첨부도면에 의거 더욱 구체적으로 설명하면 다음과 같다.The present invention has been devised in view of the above-mentioned defects, and is intended to facilitate user's convenience and safety by simply inserting the terminal protective cover with a simple operation of one-touch without using small tools such as a screw or a screwdriver. This will be described in more detail based on the accompanying drawings.

차단기 본체(2)의 고정홈(5)(5′)(5″)(5''')에 대응하여 착탈이 용이토록 고정턱(4)(4′)(4″)(4''')을 돌설시킨 단자 보호덮개(1)에 있어서, 덮개(1)양측단부로 추축공(3)(3′)을 천설하여 이 수축공(3)(3′)이 덮개(1)의 착탈시 탄성을 부여함과 동시에 접점부에서 발생하는 열이 상기한 수축공(3)(3′)에 의해 방열되도록 구성한 것이다.Corresponding to the fixing grooves 5, 5 ', 5 ", 5' " of the circuit breaker main body 2, the fixing jaw 4, 4 ', 4 " In the terminal protective cover (1) in which the cover is protruded, a pivot hole (3) (3 ') is installed at both ends of the cover (1), and the shrinkage hole (3) (3') is detached from the cover (1). The elasticity is imparted and heat generated at the contact portion is dissipated by the contraction holes 3 and 3 '.

도면부호중 미설명 부호 6은 드라이버이다.Reference numeral 6 in the drawing denotes a driver.

이와같은 구성을 가지는 본원 고안은 그 실사용에 있어서 제2도에서 보는 바와같이 수축공(3)(3′)을 양측으로 천설한 단바 보호덮개(1)의 일단의 고정력(4)(4″)을 좌단기 본체(2)에 형성한 일단의 고정홈(5)(5″)에 삽지한후 손가락등으로 가볍게 밀던 다른 일단의 고정력(4′)(4''')과 고정홈(5)(5''')가 맞물려저 소기의 목적을 달성하게 되는 것인데 이때 단자 보호덮개(1)의 양측으로 천설된 수축공(3)(3′)은 탄성적으로 오므러들어 압입을 용이하게 하고 단자 보호덮개(1)와 차단기 본체(2)의 파손을 방지해 주며 통전시 열을 방사시켜 단자부의 과열방지 역할을 하는 것이다. 또한, 단자 보호덮개(1)를 벗길 필요가 있을 때에는 제3도에서 보는 바와같이 차단기 본체(2)의 홈에 드라이버등을 넣고 손가락으로 단자 보호덮개(1)를 누른후 상향으로 힘을 가하면 손쉽게 벗길수 있는 것이다.The present invention having such a configuration has a fixed force (4) (4 ″) at one end of the t-bar protective cover (1), which is formed with both sides of the contraction holes (3) (3 ') as shown in FIG. ) Is inserted into one end of the fixing groove 5 (5 ″) formed in the left end main body 2, and then the other end of the fixing force 4 '(4' '') and the fixing groove 5 (5 '' ') is interlocked to achieve the desired purpose. At this time, the contraction holes (3) (3') laid on both sides of the terminal protective cover (1) elastically retract to facilitate indentation. And it prevents the damage of the terminal protective cover (1) and the circuit breaker main body (2) and radiates heat during energization and serves to prevent overheating of the terminal portion. In addition, when it is necessary to remove the terminal protective cover (1), as shown in Figure 3, insert a screwdriver or the like into the groove of the circuit breaker main body (2) and press the terminal protective cover (1) with a finger and then apply a force upward. It can be peeled off.

상기와 같은 작용의 본원 고안을 종래의 작은 나사(44)를 사용하여 차단기 본체(22)에 단자 보호덮개를 복개하고 차단기 본체(22)에 형성한 나사홈(33)에 작은 나사(44)를 죄어주는 방법에서 야기되었던 공구를 사용하는 번거로움과 많은 시간의 소요되는 불편함 및 드라이버등의 도체를 통한 감전사고의 위험성등의 재결함을 일소하고 드라이버 등의 공구의 사용없이 원텃치의 간편한 조작으로 단자 보호덮개(1)를 끼워넣기만 되는 구조로서 사용자의 편의와 안정성 및 조립시간의 단축등 그 실사용에 있어서 가치를 일층 고양시킨 실용적인 고안인 것이다.The present invention having the above-described function is applied to the breaker body 22 using the conventional small screw 44 to cover the terminal protective cover and the small screw 44 in the screw groove 33 formed in the breaker body 22. Easy operation of the original wrench without the use of tools such as screwdrivers, eliminating the hassles of using tools, time-consuming inconveniences, and risks of electric shock through conductors such as drivers. As a structure that only the terminal protective cover (1) to be inserted into a practical design that enhances the value in practical use, such as convenience and stability of the user and shortening of the assembly time.
