Description

The present invention relates to a relay jack board , and more particularly to a relay jack board to which a wiring terminal block, which is an insertion port for a wiring terminal for connecting an electric wire to a base plate, is attached.

Conventionally, in a relay jack board , electric wires are attached by soldering to wiring terminals provided in the relay jack board with the device itself installed on the switchboard. This soldering wiring requires a lot of time for the wiring work itself. Further, since the quality of wiring by soldering depends on the skill of the operator, there is a risk that wiring defects will occur due to soldering. Further, since this wiring work is performed toward the switchboard installed at the site, the workability is poor.

FIG. 7 is a side view showing an embodiment of a relay jack board 20 by a conventional soldering method. Further, FIG. 8 shows an embodiment of the relay jack board 20 of FIG. 7 with a front view.

As shown in FIGS. 7 and 8, in the relay jack board 20 , a set screw 18, a nut 17, a washer 19, and a contact piece 16a are attached to one of the base plates 2. Then, an electric wire is attached to the contact piece 16a by soldering. Further, on the other side of the base plate 2, a contact piece (not shown) to which a terminal such as a relay 10 is connected is provided, and is connected to the relay 10 (see FIG. 1) by a guide pipe 6.

In order to improve the wiring work by this soldering, a "screwless terminal wiring method" has been proposed. As shown in Patent Document 1, this screwless terminal wiring method is a method of fixing an electric wire wired by the restoring force of a spring to a terminal block device, and at the time of wiring, wiring is completed by pushing the electric wire into the electric wire wiring port. .. Then, when removing the wiring, the lever can be pushed in to elastically deform the spring and the electric wire can be removed.

Patent Document 1 describes a terminal block device that can easily replace a device without having to reconnect each electric wire when exchanging a device having a circuit board in which a plurality of electric wires are connected via a terminal block device. It has been disclosed. This terminal block device includes a terminal block base that is fixed to the circuit board of the device by soldering. In addition, a terminal block main body for connecting a plurality of electric wires is detachably attached to the terminal block base. Then, it is described that when the terminal block main body is attached to the terminal block base by screwing and tightening the mounting screw to the nut, the spring terminal connection portion of the base terminal and the base terminal connection portion of the spring terminal are connected.

By adopting this screwless terminal wiring method, the wiring work time itself has been shortened and the number of wiring defects has been reduced. In particular, workability has been improved by drastically reducing the wiring work time for the switchboard at the site.

Regarding wiring by the jack terminal device, the problem of the conventional soldering method is solved by adopting the screwless terminal wiring method. However, the contact pieces attached to the jack terminal device have various arrangements depending on the design. In addition, since contact pieces that do not use the wiring terminal block are generated, it is necessary to cover the contact pieces with a protective lid.

At present, various arrangements of these contact pieces and contact pieces that do not use the wiring terminal block are individually manufactured with wiring terminal blocks and lids to cope with them. Therefore, there is a problem that it takes time and cost to design and manufacture by individual manufacturing.

An object of the present application is to solve such a problem and to provide a relay jack board having a wiring terminal block capable of efficiently and freely responding to various arrangements of contact pieces.

In order to achieve the above object, the jack board according to the present invention is a jack board of a relay in which a wiring terminal block is attached to a base plate, and the wiring terminal block uses a base plate from a plurality of terminal block units having different shapes . A terminal block unit that matches the terminal arrangement is selected and combined, and for the part that is not used as a wiring terminal block, a lid unit that matches the terminal arrangement that the base plate does not use is selected from the variation group of the lid unit. It is characterized by being attached.

With the above configuration, the wiring terminal block is standardized as a terminal block unit. As a result, the operator who installs the jack board of the relay can select the optimum terminal block unit that matches the arrangement of the terminals on the base plate from the variations of the terminal block unit.

Further, each variation of the terminal block unit can be prepared in advance. As a result, the wiring work can be efficiently performed without spending time on the design and manufacture of the terminal block. Moreover, since it is not necessary to design and manufacture the terminal block unit individually, the manufacturing cost of the terminal block unit can be reduced.

Further, it is preferable that the jack board of the relay includes a lid unit for attaching the terminal block unit to a portion not mounted on the base plate. As a result, the lid for the contact piece that is not used as the wiring terminal block is also standardized and used as a variation of the terminal block unit. Therefore, the operator who installs the jack terminal device can select the optimum combination from the terminal block unit and the lid unit.

Further, it is preferable that the terminal block unit and the lid unit are detachably attached to the base plate of the relay jack board . As a result, each terminal block unit can be replaced individually, which facilitates work such as maintenance and wiring change, and saves labor.

Further, it is preferable that the jack board of the relay is retrofitted to the base plate with the electric wires pre-wired to the terminal block unit. As a result, the wiring work can be saved and simplified by attaching the terminal block unit in which the electric wires are wired to the base plate. In addition, the existing base plate can be easily replaced.

Further, it is preferable that the jack board of the relay has a wire wiring port in the terminal block unit, and the wire is detachably wired to this wire wiring port. As a result, each electric wire can be replaced individually, which facilitates work such as maintenance and wiring change, and saves labor.

As described above, according to the jack board of the relay according to the present invention, a standard variation of the terminal block unit can be prepared in advance, and terminals of the base plate from a plurality of terminal block units having different shapes can be prepared in advance. It is possible to select and combine terminal block units that match the arrangement of.

This makes it possible to have a wiring terminal block that can efficiently and freely respond to various arrangements of contact pieces.

Further, the wiring work can be efficiently performed without spending time in the design and manufacture of the terminal block, and since it is not necessary to design and manufacture the terminal block individually, the manufacturing cost of the terminal block unit can be reduced.
