4 and 5 show an example of a conventional structure of a movable magnet type instrument. In this case, the instrument body W is made of synthetic resin, and the magnet 2 is provided in the inner space of the bobbin 1 in which the upper bobbin 1a and the lower bobbin 1b are assembled. Is rotatably disposed and a plurality of coils 3 are provided outside the bobbin 1.
・ 4 is crossed, bobbin 1 is equipped with terminal 5, and magnet 2
A bobbin 1 is housed in a protective case 7 and a dial 8 is mounted on the bobbin 1
A recess 9a is formed in the housing 9, and the projection of the instrument body W is
1c is fitted in the recess 9a, and the head 11a of the screw 11 is screwed through the terminal 10a of the electric cord 10 and the housing 9 to the terminal 5 by turning it with a rotary tool such as a screwdriver. And the instrument main body W are attached and fixed, and the terminal 5 and the electric cord 10 are electrically connected by the screw 11.

[Problems to be Solved by the Invention] However, in the case of the above-described conventional structure, the screw 11 is inserted into the hole of the terminal 10a after mounting the instrument body W in the housing 9 and electrically connecting the terminal 5 and the electric cord 10 respectively. It has a structure in which the head 11a is rotated and screwed to the terminal 5 by a rotating tool, and the work must be performed multiple times, in this case, three times, and the work efficiency is reduced by that much, and the screw tightening It has the disadvantage that automation is difficult.

[Means for Solving the Problems] The present invention is intended to solve these disadvantages, and the gist thereof is to mount the instrument main body on one side of the housing and to provide a plurality of terminals on the instrument main body side and the housing. In which a plurality of electric cords on the other side of the housing are electrically connected, a supporting member on which the plurality of electric cords can be attached is formed, and a temporary fixing portion is formed on the other side of the housing, and the supporting member is formed. An engaging portion engageable with the temporary fixing portion is formed, and a screw is screwed to a terminal provided on the instrument main body side through a terminal provided at a wire end of the electric cord. And the instrument mounting device.

[Operation] A plurality of electric cords are attached to the supporting member, the supporting member is temporarily fixed to the other side of the housing by the engaging portion and the temporary fixing portion, and the above instrument is provided through the terminal provided at the wire end of the electric cord. Screw the screw on the terminal provided on the body side.

[Embodiment] FIGS. 1 to 3 show an embodiment of the present invention.

The same reference numerals are used for the same mode parts as those of the conventional structure shown in FIGS.

In the first embodiment of FIGS. 1 to 3, reference numeral 12 denotes a temporary fixing portion, in which case a positioning pin portion 13 and a temporary fixing pin portion 14 are formed on the other side of the housing 9 so as to project. A notched hole portion 15 is formed in the portion 14.

Reference numeral 16 denotes a support member, which has insertion portions 17 capable of receiving and inserting three terminals 10a made of synthetic resin and attached to the wire ends of the electric cord 10, and the terminal 10a has a retaining piece (not shown). And has three through holes 18 and 19a in which the head 11a of the screw 11 is located, and an insertion hole 19b into which the positioning pin portion 13 is inserted.

Reference numeral 20 denotes an engaging portion, and in this case, the supporting member 16 has a tubular portion 20a.
The tubular portion 20a has self-elasticity to form the cutout piece 20b, and the upper end of the cutout piece 20b is formed so as to engage with the cutout portion 15.

Reference numeral 21 denotes a protective wall, which is formed on the housing 9 so as to project, and has a dustproof and waterproof function.

Since the first embodiment has the above-described structure, a plurality of terminals are provided on the supporting member 16, in this case, three terminals provided at the wire ends of the electric cords 10.
10a is inserted and mounted, and the cylindrical portion 20a of the engaging portion 20 of the support member 16 is inserted.
The inner hole of 11 is inserted into the temporary fixing pin portion 14 of the temporary fixing portion 12 and the insertion hole 19b is inserted into the positioning pin portion 13 so that the cutout piece 20b engages with the cutout portion 15, whereby the support member 16 is attached to the housing 9. Can be temporarily fixed to the other side of the electric cord 10 in a non-rotating state, and in this state, the screw 11 can be screwed to the terminal 5 provided on the instrument body W side through the elongated hole 10b of the terminal 10a provided at the wire end of the electric cord 10. Therefore, the instrument body W can be easily attached to the housing 9 and the plurality of terminals 5 and the plurality of electric cords 10 can be easily electrically connected, which facilitates the assembling and automates the screw tightening. This facilitates the automatic assembly of the instrument main body W.

Although the instrument body W of the above embodiment is a movable magnet type instrument, it can also be applied to a movable coil type or eddy current type instrument.

[Advantages of the Invention] As described above, the present invention inserts the terminals provided at the wire ends of the plurality of electric cords into the supporting member, and mounts the supporting member on the other side of the housing by engaging the engaging portion and the temporary fixing portion. It can be temporarily fixed to the side, and in this state, a screw can be screwed to the terminal provided on the instrument main body side through the terminal provided on the wire end of the electric cord, which makes it easy to attach the instrument main body to the housing and Electrical connection between the terminals and the plurality of electric cords can be facilitated, which facilitates assembly, and facilitates automatic screw tightening to facilitate automatic assembly of the instrument body.

As described above, the intended purpose can be sufficiently achieved.
