Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a terminal structure of a crossed coil movable magnet instrument bobbin.

[Prior Art] Japanese Patent Publication No. 49-43348 is known as this type of crossed coil movable magnet type instrument.

4 to 6 are partial views of this conventional structure, in which a pointer shaft 52 with a permanent magnet attached thereto is rotatably provided in the inner space of a bobbin 51, and a pointer shaft 52 with a permanent magnet attached to the outside of the bobbin 51 is provided. The first, second, and third coils 53 are wound around the rod-shaped terminal 54 press-fitted into the bobbin 51, and the wire end 55 of the coil 53 and the lead wire 57 of the resistor 56 for temperature compensation, protection, etc. are positioned and soldered. is configured to do so.

[Problems to be solved by the invention] However, in the conventional structure, the lug plate 58 is caulked to the protruding end of the terminal 54, and the bobbin 51
The coil 53 is wound around the lug plate 58, and the wire end 55 of the coil 53 is wound around the lug plate 58.
Because of the structure in which the lead wire 57 of the resistor 56 is positioned and soldered, the positional relationship between the lug plate 58 and the lead wire 57 of the resistor 56 and between the lug plate 58 and the wire end 55 of the coil 53 tends to be uneven. Therefore, it is difficult to automate soldering, and the presence of the lug plate 58 makes it difficult to automatically wind the coil 53.

[Means for Solving the Problems] The purpose of the present invention is to solve these inconveniences. The terminal and the end of the resistor lead wire are located and soldered, wherein a protruding flange portion on which the end of the resistor lead wire can be placed is formed on the protruding end portion of the terminal, and the protruding flange portion The terminal structure of a crossed coil movable magnet type instrument bobbin is characterized in that the upper side is a resistive soldering part and the lower side is a coil soldering part for the wire end of the coil.

[Function] The wire end of the coil is positioned and wound by the coil soldering part below the protruding flange formed on the terminal of the bobbin, and the end of the resistor lead wire is placed on the protruding flange and soldered to the resistor. The wire ends of the coil that are positioned in the attachment section and located in the coil soldering section are soldered together.

[Example] Figures 1 to 3 show examples of the present invention.
is a bobbin of a crossed coil moving magnet type instrument,
A pointer shaft 2 with a permanent magnet attached thereto is rotatably provided in the internal space of the bobbin 1, and a coil 3 wound crosswise around the permanent magnet is wound around the outside of the bobbin 1.

Reference numeral 4 denotes a terminal, and the terminal 4 is press-fitted into leg portions 5 formed at the four corners of the bobbin 1. A flange-like protruding flange portion 6 is formed in the middle of the protruding end portion of the terminal 4. The upper side is the resistor soldering part 9 of the end of the lead wire 8 of the resistor 7, the lower side is the coil soldering part 11 of the wire end 10 of the coil 3, and the screw part 12 of the inner end of the terminal 4 is attached to the screw part 12 (not shown). The circuit terminals are connected.

13 is a lead wire terminal, and lead wire terminal 1
3 is crimped to the end of the lead wire 8 of the resistor 7, and the lead wire terminal 13 is formed with a groove 14 large enough to be temporarily press-fitted into the resistor soldering portion 9 of the terminal 4.

Since this embodiment has the above configuration, the end of the lead wire 8 of the resistor 7 is placed on the protruding flange 6 formed on the terminal 4 of the bobbin 1, and the end of the lead wire 8 is connected to the resistor soldering portion 9. The wire end 10 of the coil 3 can be positioned to the coil soldering part 11 on the lower side of the protruding flange 6, and therefore the end 10 of the coil 3 and the end of the lead wire 8 can be soldered while being positioned. This allows the wire end 10 of the coil and the end of the lead wire 8 to be soldered together, facilitating the automation of soldering, and in this case, the recessed groove 14 of the lead wire terminal 13.
This allows the positional relationship between the terminal 4 and the lead wire 8 of the resistor 7 to be determined, and since there is no lug plate 15, automatic winding of the coil 3 can be easily achieved.

In the above embodiment, the lead wire terminal 13 is crimped onto the lead wire 8 of the resistor 7, but it is also possible to wrap the lead wire 8 directly around the resistor soldering portion 9 without using the lead wire terminal 19. Applicable.

[Effects of the invention] As described above, the present invention allows the end of the resistor lead wire to be placed on the protruding flange formed on the terminal of the bobbin to position the end of the lead wire on the resistor soldering part, and the protruding flange The wire end of the coil can be positioned at the coil soldering part on the lower side of the part. Therefore, by positioning and soldering the end of the coil and the end of the lead wire, the end of the coil and the end of the lead wire can be positioned. can be soldered together, making it easy to automate soldering, and since there are no lug plates, it is also easy to automatically wind the coil.

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