Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a terminal block device for a printed circuit board, and particularly relates to an improvement of a terminal block device that improves the mounting density of printed circuit boards mounted on a motherboard.

2. Description of the Related Art In general, a printed circuit board is used by being removably mounted on a unit equipped with a motherboard. However, the lever unit usually accommodates a large number of printed circuit boards at the same time, and each printed circuit board is provided with a connector and wires are drawn out.
Such a conventional terminal block device for a printed circuit board will be explained with reference to FIGS. 6 to 8. FIG. 6 is an assembled and disassembled perspective view, and in the figure, 1 is the motherboard 1a.
(Fig. 8) Printed circuit board to be inserted and removed, 2 is fixed side connector, 3 is pin terminal, 4 is fixed side connector 2
4a is the nut thereof, 5 is the movable side connector, 6 is the wiring, 7 is the wiring tightening screw, 8 is the screw for tightening and fixing the movable side connector 5 to the fixed side connector 2, 9 is a lid through which the name plate 9a is inserted and the wiring connection portion 10 can be opened and closed. The wiring connection portion 10 has a stepped portion extending toward one side inside the lid 9, and a mounting portion 12 for the screw 7, which is divided by a partition wall 11, is formed in each stepped portion. Therefore, one side of the mounting portion 12 is open without a wall partition or the like. Therefore, the wiring 6 was inserted and fixed from the long side of the movable connector 5 into a specific mounting portion 12 at a predetermined step, and connected to the connecting conductor 13 with the wiring tightening screw 7.
In this way, the wiring 6 is connected to the movable connector 5 orthogonally, so that it is also mounted orthogonally to the printed circuit board 1.

Problems to be solved by the invention However, according to the above-mentioned conventional technology, the seventh
As shown in the perspective view of the figure and the plan view of figure 8, the wiring 6
are pulled out in a direction perpendicular to the printed circuit board 1, so the interval dimension D between the printed circuit boards 1 must be determined by taking into account the amount of deflection of the wiring 6, etc., which reduces the mounting density of the printed circuit board 1. The unit was prevented from becoming more compact.

Means and Effects for Solving the Problems In order to solve the above problems, the present invention attaches a fixed side connector to the side end of a printed circuit board that is inserted into and removed from the motherboard, and a movable side connector that can be freely connected to and detached from this connector. In the terminal block device, the movable side connector has a rib protrusion formed in the longitudinal direction approximately at the center of the non-engaged/disengaged side, and a plurality of partition walls are arranged symmetrically at regular intervals on both left and right sides of the rib protrusion. A terminal block device for a printed circuit board, wherein connection conductors having wiring connection parts are fixed to the side and top surfaces of rib protrusions formed and surrounded by the partition walls, and a lid body that is perpendicular to the partition walls is provided so as to be openable and closable. Configured.

By adopting such a method, the wiring is mounted parallel to the printed circuit board without being perpendicular to it, and without protruding between the printed circuit boards, thus reducing the spacing between the printed circuit boards and increasing the mounting density of the printed circuit boards relative to the motherboard. improve.

Embodiments Embodiments of the present invention will be specifically described below with reference to FIGS. 1 to 5. Fig. 1 is an exploded perspective view corresponding to Fig. 6, Fig. 2 is a plan view corresponding to Fig. 8, Fig. 3 is a cross-sectional view of the movable connector, Fig. 4 is a perspective view of the connecting conductor, FIG. 5 is a longitudinal sectional view similar to FIG. 3, showing another embodiment of the movable connector.
In the figures, the same reference numerals as in FIGS. 6 to 8 indicate the same parts, and redundant explanations will be omitted.

In this embodiment, the lid body 9 is the movable connector 5
It is provided so that it can be opened and closed on one side, while all other sides are open. Therefore, a rib protrusion 15 is provided at the longitudinal center of the movable connector 5.
A sternum-shaped partition wall 11 is formed on both left and right sides of the rib protrusion 15, and a portion partitioned by the partition wall 11 serves as a mounting portion 12. In this case, the connecting conductor 13 having the shape shown in FIG. 4 is attached in the structure shown in FIG.
The wiring tightening screw 7 is perpendicular to the rib protrusion 15 through the through hole 14, and tightens and fixes the connecting conductor 13.

Therefore, as shown in FIG. 2, the wiring 6 fits within the thickness of the movable connector 5 and can be connected without protruding between the printed circuit boards 1, so that the distance D between the printed circuit boards 1 is reduced. ₁ is reduced (D>D ₁ ), and the mounting density of the printed circuit board 1 can be improved.

In addition, in FIG. 5, the shape of the rib protrusion 15 is structured in steps, and a part of the connecting conductor 13 is bent so as to be in close contact with each step. The screws 7 can be attached from two directions at different positions, and in some cases, the wiring can be drawn out orthogonally to the printed circuit board 1 as in the conventional method, so that the screws 7 can be used in combination.

Effects of the invention According to the invention described above, since the direction in which the wiring is drawn out is the same as the direction in which the printed circuit board is inserted and removed, the wiring fits within the thickness and width dimensions of the terminal block device and does not protrude between the printed circuit boards. Therefore, the dimensions between the printed circuit boards can be reduced, the mounting density of the printed circuit boards can be improved, and the unit can be made more compact.

Further, the connecting portion between the wiring and the connecting conductor is protected by the partition wall and the lid, and can be clearly distinguished and insulated from other adjacent connecting portions. In addition, since the wiring connection part is fixed on two sides with different directions, if there is a need to connect the connecting conductor and the wiring in the same direction as before, it can be done immediately. It has the following effects.
