Description

[Detailed Description of the Invention] This invention relates to a terminal block, and particularly to a device for attaching a dustproof cover to a terminal block.

The dustproof cover of the terminal block is used to protect the terminal block mounted on a panel etc. from dirt such as dust and oil. Conventionally, as shown in Fig. 1, the base 1a of the terminal block 1 is used as a means for attaching the dustproof cover. A plurality of terminal fittings 2 and terminal screws 3 are arranged in the terminal, and each terminal screw 3
The space is separated by a barrier 1b, and the base 1a
A through hole 1d having stepped portions (not shown) at both ends,
Side walls 1c, 1c having 1d are provided,
Insert the mounting screws (not shown) into the through holes 1d, 1d, and insert the lead piece 2a of the terminal fitting 2 into the hole (not shown) provided in the panel (not shown). Fix terminal block 1 to
The dustproof cover 4 was installed on the terminal block 1 by fitting the protrusions 4a, 4a provided on the dustproof cover 4 into the through holes 1d, 1d, but this mounting means caused vibrations and shocks. There is a risk that the dustproof cover 4 may come off due to
Since it is necessary to provide a
Furthermore, there was a drawback that the length of the terminal block 1 was limited to a certain length.

This invention was proposed in order to improve the above-mentioned drawbacks, and its purpose is to provide a dustproof cover attachment device for a terminal block that prevents the dustproof cover from coming off the terminal block due to vibrations, shocks, etc.

This invention will be explained below based on an embodiment shown in FIGS. 2 and 3. Components that are the same as those in FIG. 1 are designated by the same reference numerals.

1 is a terminal block, and a plurality of terminal fittings 2 are mounted on the base 1a.
and terminal screws 3 are arranged in parallel, and each terminal fitting 2
Lead pieces 2a are arranged to protrude from the bottom surface of the base 1a, barriers 1b are formed on both sides of each terminal screw 2, and flange portions 1e are formed on both sides of the longitudinally lower part of the base 1a. , 1e, and a fitting recess 1f is provided at the bottom of the base 1a corresponding to each barrier 1b.

4 is a dustproof cover made of synthetic resin.
Notches 4b are provided at regular intervals on both sides, and a groove 4c is formed between the notches 4c and 4b. By cutting the groove 4b, the dustproof cover 4 can be cut to a desired length. It can be used as

Reference numeral 5 denotes a terminal block mounting device for mounting the terminal block 1 to the panel 7. A through hole 5b is provided in the center of the mounting base 5a, and the mounting base 5 is located below the through hole 5b.
A screw 6 is embedded in the part a, and a substantially cross-sectional mounting portion 5c is integrally formed on the mounting base 5a, and vertical pieces 5d, 5d provided on this mounting portion 5c are attached to the terminal block 1. It is disposed so as to fit into the fitting recesses 1f, 1f.

A panel 7 has a mounting hole 7a for the terminal block 1 and holes 7b, 7b formed on both sides of the mounting hole 7a.

Reference numeral 8 denotes a dustproof cover holding device, in which a hole 8b is provided in the center of the base 8a, and mounting pieces 8c, 8c are provided on both sides of the base 8a.
Claws 8d, 8d for locking the dustproof cover 4 are formed at the tips of c, 8c.
Attach the mounting pieces 8c, 8c to the notches 4b, 4b of the dustproof cover 4 so that the dustproof cover 4 is located under d.
to be inserted into. By fitting the mounting pieces 8c, 8c into the notches 4b, 4b, the dustproof cover 4 is prevented from shifting from side to side.
The claw portions 8d, 8d of c prevent the dustproof cover 4 from shifting upward, and the barrier 1b of the terminal block 1 prevents it from shifting downward.

Next, to explain the installation work, insert the terminal block 1 into the mounting hole 7a provided in the panel 7 from the back side of the panel 7, and attach the terminal block 1 to the periphery of the mounting hole 7a.
The fitting recesses 1f, 1 are arranged so that the flanges 1e, 1e of the terminal block 1 are in contact with each other, and are provided at the bottom of both sides of the terminal block 1.
Insert the vertical pieces 5d and 5d of the mounting device 5 into the holes 7b of the panel 7 into the holes 5b of the mounting base 5a, respectively.
be arranged accordingly. Then, from the front side of the panel 7, insert the dustproof cover holding device 8 into the hole 8b of the base 8a.
are arranged to correspond to the holes 7b of the panel 7, and the mounting screws 9 are inserted into the holes 8b of the base 8a, the holes 7b of the panel 7, and the through-holes 5b of the mounting base 5a.
After fixing the mounting device 5 and the holding device 8 to the panel 7 with the screws 9 embedded in the panel 7, the mounting pieces 8c and 8c are fitted into the notches 4b and 4b of the dustproof cover 4, respectively, and the dustproof cover 4 is attached to the terminal block 1. to be placed.

As described above, the fitting recess and flange are provided in the base of the terminal block, the terminal block is fixed to the panel by the dustproof cover holding device and the terminal block mounting device, and the dustproof cover is attached to the fixed holding device. By simply attaching and placing it on the terminal block, you can prevent the dust-proof cover from coming off due to vibrations and shocks.In addition, fitting recesses are formed at the bottom of the base that correspond to each barrier of the terminal block. Therefore, the length of the terminal block is not limited, and the terminal block can be used at a desired length, which has a practical effect.
