JPH04141971A - Penetration terminal block - Google Patents

Abstract

PURPOSE:To obtain a penetration terminal block requiring no separately installed Faston terminal or the like in connection of a secondary cable providing a primary cable connection part for connecting the primary side with a primary cable, a board connection part for connecting a secondary terminal itself with a wiring pattern of a printed wiring board, and a secondary cable connection part for connection with the secondary side cable. CONSTITUTION:A secondary side is composed of a lead 4a for connection with a printed wiring board 5, and a tab 4b for Faston terminal for connection with a secondary cable, and a primary side is composed of a terminal screw 2. In this case, for a penetration terminal block, connection with a wiring pattern 6 of the printed wiring board 5 and connection of a customer side primary cable 3 are performed in similar procedures as in a conventional penetration terminal block, and a secondary cable 8 on an electric appliance side is directly connected with the tab 4b for Faston terminal formed at the connection terminal 4. The secondary cable can thus be connected without separately installing a Faston terminal or the like or increasing the number of parts of the penetration terminal itself.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal block that connects a primary electric wire on the negative side and connects a printed wiring board and a secondary electric wire on the secondary side.

[Prior Art] Fig. 3 shows a conventional through terminal block, in which (a) is a plan view;
(b) is a front view, and (c) is a sectional view taken along line AA in (b). In the figure, (1) is a resin case, (2) is a terminal screw for tightening the primary wire on the negative side, and (4) is connected to the terminal screw (2).
This is a connection terminal formed with a lead (4a) that connects to the wiring pattern of the printed wiring board on the secondary side.

FIG. 4 is a perspective view illustrating a case where the through terminal block of FIG. 1 is used as a customer terminal block for electrical equipment. In the figure, the same reference numerals as in FIG. 4 indicate the same or corresponding parts.

(3) is the negative side electric wire, (8) is the secondary side electric wire, (5) is the printed wiring board of electrical equipment, (6) is the wiring pattern of the printed wiring board (5), and (7) is the secondary side This is a printed wiring board mounting type Faston terminal that is separately installed on the printed wiring board (5) to connect the electric wire (8).

As is clear from FIG. 4, this through terminal block is connected to the printed wiring board (5) by inserting and soldering the leads (4a) at predetermined positions on the printed wiring board (5). The connection of the primary electric wire (3) on the primary side, which is the customer side, is made by tightening and fixing the terminal screw (2). The connection of the secondary side wire (8) on the secondary side inside the electrical equipment is as follows:
This is done by separately installing a printed wiring board-mounted faston terminal (7) on the wiring pattern (6) of the printed wiring board (5) [Problem to be solved by the invention] The conventional through-hole terminal block is as described above. Since it is configured as
When connecting the secondary side electric wire (8), it is necessary to separately install a printed wiring board mounted faston terminal (7) on the printed wiring board (5), which increases the number of parts and assembly man-hours. Furthermore, when installing the printed wiring board-mounted faston terminals (7), there was a problem in that the mounting area was also increased in order to ensure an insulating distance between them.

The present invention was made to solve these problems, and when connecting the secondary side electric wire on the printed wiring board side of the feed-through terminal block consisting of the negative side and the secondary side, Faston terminal etc. The purpose of the present invention is to obtain a through terminal block that does not require separate installation.

Incidentally, Japanese Utility Model Application Publication No. 56-140157 discloses an idea in which a connecting terminal is screwed together with a lead wire on a printed circuit board, but there is a drawback that the connecting terminal and the lead wire must be connected at the same time. Also, Utility Model Publication Hei 1-9276
No. 9 discloses an idea in which a screw terminal and a faston tab are integrated, but the configuration of the negative side and the secondary side (printed wiring board side) is not specific.

[Means for Solving the Problems] A feed-through terminal block according to the present invention is a feed-through terminal block in which a primary side and a secondary side are electrically connected via an insulating case, in which a primary side electric wire is connected to the above-mentioned negative side. A board connection part that connects the wiring pattern of the printed wiring board to the secondary side terminal itself, and a secondary side electric wire connection that connects to the secondary side electric wire. It forms a part.

[Function] In the feed-through terminal block of the present invention, on the secondary side, the board connection part and the secondary side electric wire connection part formed on the terminal itself can be connected to the printed wiring board and the secondary side electric wire, respectively. On the side, it can be connected to the primary side electric wire by the negative side electric wire connection part.

[Example] FIG. 1 shows a through terminal block showing an example of the present invention,
(a> is a plan view, (b) is a partially sectional front view, and (C) is a side view. In the figures, the same reference numerals as in FIGS. 3 to 4 refer to the same or corresponding parts. (4b) is a faston tab formed on the connection terminal (4), which has a 180# direction different from that of the lead (4a).In this example, the connection with the printed wiring board (5) Lead for (4a
), and Faston tab (4) for connection to the secondary side electric wire.
The connection terminal (4) formed in b) constitutes the secondary side, and the terminal screw (2) constitutes the negative side.

FIG. 2 is a perspective view showing the case where the through terminal block of FIG. 1 is used as a customer terminal for electrical equipment.

In the figures, the same reference numerals as in FIGS. 1, 3 and 4 indicate the same or corresponding parts.

This feed-through terminal block connects the wiring pattern (6) of the printed wiring board (5) and the primary side electric wire (3) on the customer's side.
The connection is made in the same manner as the conventional through terminal block, and the secondary electric wire (8) on the electrical equipment side is directly connected to the faston tab (4b) formed on the connection terminal (4).

In addition, in the above example, a terminal screw was used on the negative side and a Faston tab was used on the secondary side as a means of connecting the electric wire, but a Faston tab was used on the negative side and a terminal screw was used on the secondary side. You can also use

Further, in the above embodiment, three sets of terminal blocks on the primary side and the secondary side have been described, but the number is not limited to this number.

[Effects of the Invention] As described above, according to the through terminal block of the present invention, the board connection portion and the secondary wire connection portion are formed on the secondary side terminal itself,
The secondary side electric wire can be connected without separately installing Faston terminals, etc., and without increasing the number of parts of the through terminal block itself, reducing the number of parts and assembly man-hours.
Furthermore, costs can be reduced and reliability can be improved by reducing the mounting area of the printed wiring board.
