[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a terminal block connector used for connecting a control busbar of a switchboard or a control panel.

[0002]

[Prior art]

 As a conventional bus bar connection, as shown in FIG. 7, there is a system in which a bus bar 101 is drawn into a board 102 and sent to an adjacent board, and when a connector is used, the same method is used. When a connector is used as an example, as shown in FIG. 8, when the connector 202 is attached to one board 201, a fire due to arc loss in the adjacent board 203 or smoke having a thermal element is generated in the connector 202. Sometimes infiltrated through.

Further, as shown in FIG. 9, unless the concave connector 301 is removed, there is a risk that the concave connector 301 may be damaged when the board 302 is moved even if the convex connector is pulled out. there were. In addition, some conventional terminal block connectors consist of molded products that house multiple contacts. In case of multiple poles, male contact and female contact are built in and connected to the integrated male and female cases respectively.Although it has a unit structure, the male contact is in the male unit and the female unit is in the female unit. There were things that could incorporate and connect contacts. These are what are commonly referred to as standard connectors. However, there was no terminal block connector provided with a so-called spring-up type screw holding terminal in the terminal block section of the terminal block connector.

[0004]

[Problems to be solved by the device]

 The present invention is intended to solve the above-mentioned drawbacks and to provide a connector that prevents damage to the concave side connector and adverse effects between the boards. A connector is one in which multiple contacts are connected at equal pitch intervals by insertion and removal, and an error between the pitches causes a decrease in contact reliability. In addition, it is sometimes said that the load for insertion and extraction is so heavy that the load is relatively heavy during insertion and extraction. Furthermore, when wiring the terminals with screws, it is desirable to add a spring-up type screw holding mechanism for convenience of connection, but it is difficult for the connector to be configured in a normal shape. Met. Moreover, forming contacts in the horizontal and vertical directions with respect to the terminals was not seen in the integrated connector but was seen in some of the unit systems, but many are taken in the unit. Therefore, there is a problem in that the molding accuracy of the unit is incorrect, and when many units are tightened with bolts, etc., deformation occurs and the dimensions change, which affects plug insertion / removal and reduces contact reliability. Came.

[0005]

[Means for Solving the Problems]

 Therefore, in view of the above circumstances, the present invention is designed so that the insertion portion of the concave connector is located on the mounting side of the panel so that the concave connector does not protrude from the panel. In addition, the shape of the concave connector part is that the contact is wrapped with non-combustible resin and the space between the panel and the contact is sealed.

Further, in view of the above-mentioned circumstances, the present invention is configured such that the plug side is integrally formed, and the socket side that receives the plug side is also integrally formed. However, the socket side has a unit that houses the terminal portion and the contact portion. The socket part of the connector was formed by inserting into the integrated molding on the socket side. The unit part is formed horizontally and vertically to the terminal part, and the contact at the lower position of the terminal part is fitted on one side of the unit, and the contact at the higher position of the terminal part is fitted on the other side to create a zigzag state of the terminal part. After the contacts were formed on the socket of the connector, they were tightened with bolts to form the terminal block connector.

[0007]

[Action]

 In the present invention, the panel is not damaged at all, and the invasion of combustion gas, which affects the adjacent control panel, is prevented in advance. Further, in the present invention, the expansion of the variation due to the dimensional error is eliminated by the unit instead of the integrally molded plug and socket, and the connector can be inserted and pulled out smoothly to improve the contact reliability. In addition, a spring-up type screw holding structure, which is possible with the unit structure, is housed and integrated with the plug, which provides convenience in connection work.
