The wire (L) can be easily pulled out because the pressure on the running wire is reduced.

[0020]

[Action]

 The modular jack terminal block configured as described above has a slit (2) formed in the center of the front of the case (K), and this has a connecting piece (3) hung vertically on the lower side of the back plate. When the terminal member (A) is held by fitting the slits (2) to the protrusions (13) of the holding plate (12) of the separator (11), the outside of the case (K) is aligned with this positioning. The push button (7) and each connecting piece (3) are in the correct positions so that the whole body can be held at equal intervals by the partition body (15), and therefore, when housed in the box body (R) of the holder (B), Each push button (7) exactly matches the surface hole (H1) of the box body (R), and the push button (7) can be pushed out to the outside, and each connection piece (3) has a box ( R) can be projected in a line and on the opening side, so that the printed wiring board (C) can be projected. Those which develops the same time act to insert connecting the connection piece (3) in the connection hole (H5).

The protrusion (9) of the release push button (O) is located between the pair of springs (S), and the lower contact piece (10) has the protrusion (9) when the push button (7) is pressed. Is positioned between the springs (S) and acts as a guide for vertical movement, and at the same time, the contact piece (10) contacts the pedestal (12) of the separator (11) and the push button (7) slides into the case. Has the effect of exhibiting motion.

The front downward C-shaped frame body (22) of the base (D) contacts the rear surface of the modular jack (M) connected to the printed wiring board (C), and thus applies external pressure to the modular jack. It acts to receive. In addition, since a pair of grooves (34) are formed on the back surface of the base (D), even if dew drops collect on the back surface of the base, the grooves (34) flow out of the base and have a moisture resistance effect on the equipment. It is what makes up.

[0023]

[Effect of device]

 The effects of this device configured as described above are listed below. First, the terminal member (A) is miniaturized, and the terminal member (A) is regularly assembled by the separator (11) so that each push button (7) can be accurately exposed through the push button exposure hole (H1) of the holder (B). Moreover, since the contact pieces (3) are aligned in a line and project at the correct intervals, they can be correctly inserted into the connection holes (H5) of the printed wiring board (C) at the same time, which is extremely accurate in assembly work. There is an advantage that can be implemented. Secondly, since the terminal member (A) is not directly connected to the printed wiring board (C) but is housed and connected in a holder, there is an advantage that external pressure on the terminal member (A) can be protected. Thirdly, the housing (23) of the modular jack (M) is housed between the right-side upright plates (32) of the base (D), and the housing (23) has the ridges (24) upright (32). Since it is fitted and locked in the locking elongated hole (33), there is an advantage that parts can be assembled reliably. Fourthly, since the groove (34) for outflow of dew droplets is provided on the back surface of the base (D), there is an advantage that the moisture-proof effect can be enhanced for the device. Fifth, since the cover (E) is provided with cutout portions (41) for drawing out electric wires on both sides and the back surface, there is an advantage that the pulling-out direction of the connecting electric wire (L) can be freely selected. It is a practical device that has the effects of.
