Description

  The present invention relates to a terminal board for connecting large-capacity electric wires.

  Conventionally, the connection terminal of the wiring is usually processed by flattening the end of the electric wire, sandwiching the end between the connection plate and the washer, and tightening.

In addition, a structure has been proposed in which a through-hole type terminal block is used and a connecting tool is arranged in parallel in a terminal block bank.

  In the conventional terminal block and the like, since the wire end is flattened and fixed by tightening, not only the processing of the wire end becomes an essential requirement, but also when the tightening force of the tightening bolt is weak, the wiring insertion direction. There is a possibility that the conductors may deviate and approach adjacent wirings, causing dielectric breakdown.

  Further, in order to prevent the dielectric breakdown, there is a problem that the terminal board is enlarged or the insulating partition walls are formed to have a sufficient size, thereby complicating the structure and increasing the size.

  However, the present invention solves the above-mentioned conventional problem by connecting the terminal to the connecting tube of the terminal plate while stripping off the insulating coating of the end of the large-capacity electric wire (for example, 38 mm to 250 mm in diameter).

  That is, the present invention is a terminal board characterized in that a terminal plate having a connection cylinder is fixed by superimposing on a conductive plate in each section provided with vertical and horizontal insulating partitions on an insulating base. Insulating bases are alternately arranged in parallel, and the insulating partition walls and the insulating base are integrated by through bolts, and terminal plates having connection tubes are fixed to the conductive plates in the respective sections by overlapping each other. It is a terminal board.

  Further, another invention is characterized in that terminal plates on which a connecting cylinder is eccentrically connected to a plate body are stacked and fixed on conductive plates in each section provided with vertical and horizontal insulating partitions on an insulating base. A terminal board, wherein an insulating partition wall and a terminal plate having a connection cylinder are respectively fixed to conductive plates in respective sections of a section insulating stand in which the insulating stand is integrally assembled by through bolts, and the terminal board is fixed. It is a board.

  In the above invention, the terminal plate is a flat plate having a necessary area, and the connecting cylinder is cut out from the flat plate and formed into a cylindrical shape, so that not only is it easy to manufacture, but also it is fully automatic with good dimensional accuracy. In addition to molding, the cross-sectional area of the flat portion and the connecting portion of the connecting tube can be made necessary and sufficient. For example, the thickness of the flat plate can be arbitrarily selected, and the cut amount at the time of forming the connection tube can be freely selected.

  If the terminal board is assembled, the height and thickness of the partition wall and the distance between adjacent parts can be freely selected, and complicated irregularities can be easily formed. (Because each partition becomes a simple form if it is a component).

  In this invention, the terminal board having the connection cylinder is overlapped and fixed on the conductive plate in the section defined by the vertical and horizontal partition walls, so that the connection end of the large-capacity wiring is held and fixed in a predetermined direction, and the external force is fixed. Since there is no change in direction, there are various effects such as no possibility of causing dielectric breakdown during use.

  In addition, the terminal board is made up of an insulating base and an insulating partition in parallel, and the whole is fastened and fixed with through bolts. Therefore, even if the overall shape becomes complicated, each member can be simplified, and the effect of reasonably mass production is possible. There is.

  In the present invention, a terminal plate in which a connecting cylinder is eccentrically connected to a plate body is fixed to a conductive plate in each section formed by providing vertical and horizontal insulating partitions on an insulating table, and the terminal plates are fastened by bolts, respectively, and overlapped. .

  The insulating table and the insulating partition are alternately arranged in parallel, and a common through bolt is inserted into the insulating table and the insulating partition to be integrally fastened and fixed. A terminal board is overlapped with a plate body of a terminal board and fastened with bolts, and each is fixed to form a terminal board.

  The present invention will be described with reference to an embodiment. An insulating base 2a is arranged in parallel with an insulating partition 1a on the left side of FIG. 1, an intermediate insulating partition 3a is arranged next to the insulating base 2a, and then an insulating stand 2b is arranged in parallel. An intermediate insulating partition 3b is arranged on the right side, an insulating base 2c is arranged on the right side, an insulating partition 1b on the right side is arranged on the right side, and a recessed portion 4a, 4b is formed in the center of the intermediate insulating partition 3a, 3b. A central insulating partition 5 is fitted into the recessed portions 4a, 4b, and through bolts 6, 6 are inserted into front and rear lower portions of the left and right insulating partitions 1a, 1b. 7, the through-bolts 6, 6, 7 are fastened and fixed to integrally form the insulating bases 1a, 1b, 1c and the insulating partitions 1a, 1b, 3a, 3b.

  The terminal board 10 of the present invention is completed by fixing the terminal plates 8 and 8 to the conductive plates in each section formed as described above with bolts 9 and 9 respectively.

  The terminal plate 8 is formed by connecting a connecting cylinder 12 to a plate 11 and forming a bolt hole 13 in the plate 11.

  In the figure, reference numeral 14 denotes a conductive plate in contact with the lower surface of the plate.

  The above-described embodiment is the terminal board 10 for connecting a large-capacity electric wire 14 (for example, a diameter of 38 mm to 250 mm). However, if the electric wire 15 is inserted into the connection tube 12, the connection between the electric wire 15 and the terminal plate 8 is reliable. Yes, once connected, the terminal plate is fixed and secured between the wires with sufficient insulation spacing, so there is no risk of dielectric breakdown.
