Description

실험실습용 회로기판 고정대Lab Board Fixture

본 발명은 전자의 회로도에 맞추어서 전자부품을 연결결합시킴으로 실험 및 실습을 하는 회로기판을 고정설치하고, 전자부품을 내장보관하기 위한 실험실습용 회로기판 고정대에 관한 것이다.The present invention relates to a circuit board holder for laboratory training for fixing and installing a circuit board for experiment and practice by connecting and coupling electronic components in accordance with the electronic circuit diagram, and internally storing the electronic components.

일반적으로 전자의 회로도가 제대로 작성이 되었는지를 알아보도록 하는 전자부품을 결합 및 분해를 할수 있도록 된 실험실습용 회로기판을 다수개를 구비하여 상호 접하도록 한 상태에서 비전도체인 패널에 실험실습용 회로기판을 고정설치하여 사용을 하고 있는 실정이었다.In general, a laboratory training circuit board is placed on a non-conducting panel with a plurality of laboratory training circuit boards that can be combined and disassembled to allow electronic components to check whether the electronic circuit diagram is properly prepared. Fixed the situation was used.

그러나 이와같이 패널에 실험실습용 회로기판을 고정설치하여 사용을 함으로 외견상 조잡하게 됨을 알수 있었고, 사용자의 부주의로 인하여 실험실습용 회로기판 및 이에 결합시켜 놓은 전자부품들이 휴대시에 손상을 많이 입게 됨으로 인하여 새로이 구입을 하여야 하는 등의 단점이 있었다.However, it can be seen that the laboratory practice circuit board is fixedly installed and used in this way, and it is seemingly coarse, and due to the carelessness of the user, the laboratory practice circuit board and the electronic components connected thereto are damaged a lot when being carried. There were disadvantages such as the need to purchase.

그리고 실험실습용 회로기판과 전자부품을 각각 별도로 휴대를 하도록 되어 있어 실험실습용 회로기판이나 전자부품들을 분실하게 되는 등으로 인하여 이 또한 새로이 구입을 하여야만 함으로 전자 회로도가 제대로 작성이 되었는지를 확인 및 실험실습을 하기 위해 전자부품과 실험실습용 회로기판의 구입비가 증가되는 등의 단점이 있었다.In addition, because the circuit board and electronic parts for the lab training are to be carried separately, the lab circuit board and the electronic components are lost. Also, the new circuit must be purchased. To this end, there were disadvantages such as an increase in the purchase cost of electronic components and laboratory circuit boards.

또한 사각 함체형상으로 형성한 실험실습용 회로기판 고정대가 있으나 이는 전방측이 후방측보다 낮게 형성을 하여 항상 전방에서만 작업을 하도록 되어 있어 전자회로도에 따른 전자부품을 결합하기 위해서는 일측방향에서만 작업을 하여야만 함으로 매우 불편하였었고, 전자부품을 수납할 공간이 고정대에 설치되어 있지를 않아서 별도의 수납함에 전자부품을 보관 및 휴대를 하여야만 하는등의 문제점이 있었다.In addition, there is a laboratory practice circuit board holder formed in the shape of a rectangular enclosure, but the front side is formed lower than the rear side so that the work is always performed only in the front. It was very inconvenient, and there was a problem that the electronic parts should be stored and carried in a separate storage box because the space for accommodating the electronic parts was not installed in the holder.

본 발명은 이와 같은 단점으로 안출된 것으로 상부 양측으로 인출단자와 전원단자를 설치한 고정대의 상부측에 실험실습용 회로기판을 고정설치하고, 하부내측으로 전자부품을 각각 종류별로 분리하여 보관하는 수납함을 내장설치함으로서 휴대시에 고정대 하나만을 휴대함으로서 휴대의 불편함을 없애며, 고정대의 상부측을 수평형태로 형성을 하여 사방 어느 방향에서도 작업이 용이하도록 하도록 하는데 주 목적이 있는 것이다.The present invention has been devised as a drawback to such a drawback that the laboratory circuit board is fixed to the upper side of the fixing unit installed with the drawer and the power supply terminal on both sides of the upper side, and the lower box to separate and store the electronic components for each type. The main purpose is to remove the inconvenience of the portable by carrying only one holder when carrying the built-in installation, and to form the upper side of the holder in a horizontal form to facilitate the operation in any direction.
