Description

[Detailed Description of the Invention] This invention relates to an arc welding machine in which a protective cover is provided on the terminal portion. Some arc welding machines are equipped with protective covers over their input terminals and output terminals.

FIG. 1 shows this type of arc welding machine, in which a protective cover is provided at the output terminal section. A protective cover 5 is provided at the lower part of the front panel 2 of the arc welding machine 1 over output terminals such as an output terminal 3 and a metal outlet 4, and the output terminals can be opened and closed by a hinge 6.

Conventionally, this protective cover 5 has been used to protect output terminals 3 and metal outlets 4, as shown in FIGS. 2 and 3.
When connecting or disconnecting welding cables, control cables, etc., the cable is lifted in the direction of the arrow shown in FIG. 2 and latched to the front panel 2. 7
is the locking tool, and the receiver 7a on the front panel 2 side
and a fitting tool 7b on the protective cover 5 side. However, in this case, not only the locking tool 7 itself is required, but also the alignment of the receiving tool 7a and the fitting tool 7b requires considerable attention to the dimensional accuracy of the respective mounting positions. Furthermore, even if it is necessary to attach electrical components such as a meter 8, a switch 9, a fuse 10, etc. to the front panel 2 within the area indicated by 1 in FIG. However, there were drawbacks such as the range of these mounting positions was naturally restricted.

This invention provides an arc welding machine that has a simple structure and is provided with a protective cover that can easily expand the mounting range of electrical components if necessary.

FIG. 4 shows an embodiment of this invention, and the same reference numerals are used for the same parts as in the conventional example. At the top of the front panel 2 of the arc welding machine, electrical parts such as a meter 8, a switch 9, and a fuse 10 are installed, as in the conventional case, and at the bottom, an output terminal 3 for connecting a welding cable and a control cable are installed. An output terminal section such as a metal outlet 4 for connection is provided. A protective cover 11 covering the upper and front parts of the output terminal section is fixed to the front panel 2. As shown in FIG. 5, the protective cover 11 is
It is divided into a movable part 12 and a fixed part 13 at the middle part of the upper part, and each part is connected by a hinge 14. The bent end portion of the fixing portion 13 is fixed to the front panel 2 with screws 15 or the like. Note that 16 is a cover holder, and in this case, both sides of the underframe of the arc welding machine are extended, the tip thereof is bent, and a screw hole 17 is provided. 18
is a screw, which is screwed into the screw hole 17 of the cover receiver 16 and fixes the protective cover 11 through the screw hole provided in the protective cover 11.

The protective cover 11 is always supported by the cover receiver 16 and covers the output terminal section. When connecting or disconnecting the welding cable or control cable, the movable part 12 is lifted to open the output terminal part. When the movable part 12 is lifted, the movable part 12
As shown in FIG. 4, the hinge 14 rotates in the direction of the arrow and is folded back to the position indicated by the two-dot chain line. The movable part 12 is connected to the fixed part 13.
be accepted and supported. Therefore, when the protective cover 11 is fixed to the front panel 2, it always covers the output terminal part and leaves the output terminal part open.
When the movable part 12 is supported by the fixed part 13,
Any position that does not interfere with the electrical components attached to the front panel 2 is sufficient.

FIG. 6 shows another embodiment of this invention, in which the movable part 12 of the protective cover 11, which is shown using a two-dot chain line in FIG. This is carried out in cases where there is interference with electrical parts such as the meter 8, switch 9, fuse 10, etc. when returning. In this invention, the movable part 12 of the protective cover 11 is folded back and is received and supported by the fixed part 13, so that the position of the protruding part of the electric component and the substantially upright part of the movable part 12 of the protective cover 11 are It is very easy to provide a distance of 2 between the two. That is, the protective cover 11
The mounting position of the hinge 14 may be considered, or the length of the fixing portion 13 of the protective cover 11 may be extended as appropriate.

As mentioned above, this invention eliminates the need for a special locking tool to lock the protective cover, and saves the effort required for processing. Its effects are remarkable, such as the effective use of area, miniaturization of equipment, and cost reduction.
