Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed circuit board connection socket with separate input/output terminals, and in particular, an object of the present invention is to provide a printed circuit board connection socket that is easy to wire, maintain, etc.

Generally, an electronic device I/i1 such as a sequence controller
Sockets that have one digit fΣ, such as output relays, include back-wired sockets and front-wired sockets.For example, a back-wired socket SB as shown in Fig. 1 is installed in a housing such as a panel of a power distribution board. When the relay R7 is installed and used as a receiving body, a terminal block T is pre-arranged on the outer surface of the housing H near the SB. Connect 1 from the output terminal group po of the socket SE protruding 1111K from the body H.
14N, connect the terminal block T to the terminal block PTK protruding into the housing H, and connect the relay R from the terminal block T outside the housing H.
A configuration is adopted in which the input terminal p+ of the socket SB is connected to a power supply or the like in the housing H, while allowing the output of the socket SB to be taken out. In addition, as shown in Figure 2, in the case of a surface wiring type socket SS that is installed and used on the surface of the housing H, the output terminal group of the socket SS is located outside the housing H, so a separate terminal block is required. However, it is necessary to connect the input terminal P1 to a power source or the like inside the housing H through a through hole HO formed in the housing H via a connecting line N. Therefore, in the former case, a terminal block T is required in addition to the socket (SB), which not only makes the device expensive but also makes the wiring work complicated. In addition, in the latter case, it is necessary to take the trouble to form a through hole Ho for introducing the connection line ■ into the housing H.
It has the disadvantage of being troublesome.

This invention has been made in view of the above points, and an output terminal block is formed on one side of a base from which a relay can be removed, and a print is printed on the side of the base opposite to the output terminal block or on the bottom of the base. This is characterized in that a board connection portion is formed.

The present invention will be described in detail below with reference to FIGS. 3 to 6. 117t.

The socket is generally constructed by forming a lead-out terminal block 3 in a step shape on one side of the base 2 (the illustrated example shows a single-pole type).
IF has relay terminals 41, 42, 4 on the top surface.
The socket holes 2+, 22° and 23.24 into which 3.44 can be inserted are opened, and the sockets for the socket connection fittings 5, 6, 7.8 are opened according to the twisting force and the lower part of the socket. Plug terminal, 5t, 6t, 7
t and st are housed and fixed. It's the ridge, metal fittings 5.6.7
The other end f is formed, and the screws 9, which are led out to the lead-out terminal blocks 31, 32, and 33, are fitted into the lead-out terminals 52, 62, and 72, respectively. In addition, 31a', 32a.

33a is a barrier provided according to the height of the lead-out terminal blocks 31, 32, and 33. IQ, 11 is a notch opening, which is located in the lower chamber of the side of the country board 2 opposite to the lead-out terminal block 3. An opening is formed in the first cutout opening 10 and the bottom surface of the base 2 so as to cross the base 2 at an angle of X/-1. Between the second notches [having a corner 11, each notch opening 10, 11 reaches the lower pair (5 position) of the receiving plug hole 24 in a communicating groove 12.
A plug connecting fitting 8 having one end extending inwardly into the receiving hole 24 is inserted, and the other end of the fitting 8 is exposed to either the cutout opening 10 or 11 and led out. Here, the metal fitting 80
As shown in Fig. 5, the shape of the input socket (support) element 82 is designed to have a bullet clamping part that can clamp the board-shaped terminal +3, and the printed circuit board is removable. There is. For example, in the case where a plurality of socket bodies 1 are installed together as shown in Fig. 4, by inserting a single board-like terminal 3 from the opening 10 side or 11 side, simultaneous connections can be made all at once. .

Furthermore, as shown in FIG. 6, forming the input socket terminal 82 of the metal fitting 8 into a pin shape is extremely convenient when connecting it to the board-shaped terminal 13 by soldering.

In the illustrated example, only a socket compatible with a single-pole relay was explained, but it goes without saying that the same effect can be obtained when it is used in a socket for a multi-pole relay or a socket for a control device such as an electronic timer. It is i-high. Also, it is a matter of course that only one of the IQ and 11 chair forces may be formed between the notches in the socket.

This invention has been described in detail above. First, the input terminals (l-r are connected on the back), so the output terminal is outside the cylinder and the input is inside the housing.The input and output can be separated, making the device neat and easy to arrange.・It is extremely easy to construct the space.The terminal for the cut-out terminal σ history side 4'4 &
Since it is in the form of 7, direct connection to the printer terminal is possible. ′! Direction 7'l of the input terminal; Since it is designed so that it can be drawn out in two directions on the bottom or side surface of the socket, it has various effects such as being able to attach the eye to match the shape of the housing. .
