Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a coil terminal that enables automatic winding by directly fixing a coil terminal having a terminal screw portion to a coil spool.

[Technical background]

Various types of coils are used in electrical equipment, and Frog automatic winding equipment is used to manufacture these coils. Various terminals are attached to this coil depending on its shape and the shape of its casing.

For example, when looking at coils used in relays, etc., conventionally, after the winding work was completed, a thin plate coil terminal was inserted into the insertion hole of the coil spool, and the end of the winding wire was wrapped around the coil terminal using epoxy resin. It was fixed with

FIG. 4 specifically shows this. That is, after the coil work on the coil spool 1 is finished, the coil terminal 2 is inserted into the fixed insertion hole 6 provided at the end of the coil spool 1.
4, the winding wire is tied to the winding collar part 5 protruding from the insertion opening 4, and then an epoxy resin or the like is applied to the cutout part 6 provided in the insertion opening 4 to fix it. Note that 7 in the figure
1-j relay terminal, which was screwed to coil terminal 2.

When using this conventional method, since the coil terminal 2 is a thin plate and has a long and narrow pinion length, the stress during fixing the relay terminal 7 and the coil terminal 2 or the stress after fixing is applied to the winding collar. However, after winding, the coil terminal was inserted, the end of the coil was coated, epoxy paint was applied, and finally the relay terminal was attached. This method requires a lot of man-hours and is inconvenient, and it has been desired to develop a simpler method or member. - [Object of the invention] The present invention enables automatic winding by directly fixing a coil terminal having a terminal screw portion to a coil spool, and prevents play in the terminal and disconnection at the joint between the winding portion and the terminal. The object of the present invention is to provide a coil terminal which prevents breakage of the coil terminal without causing damage to the coil terminal.

[Summary of the invention]

The present invention has been arrived at as a result of studies conducted in response to the above-mentioned circumstances or requests. The middle part is bent with a slight inclination on one short side, and then the tip part with a threaded part is formed so that it is parallel to the open end, and a winding collar part is provided on the side of one short side, and both pieces are bent. This relates to a coil terminal whose characteristic is that a notch is provided in the side wall connecting the two.

The present invention will be explained in detail below with reference to the drawings.

[Embodiments of the invention]

FIG. 1 shows a perspective view of a coil terminal constructed according to the present invention. When a thin terminal plate material is bent into a U-shape, the length of the open end is adjusted so that a long piece and a short piece are formed.
A part of the long side is bent inward with a slight inclination, and then folded outward again so that it is parallel to the long and short pieces. A terminal screw hole 9 is provided in the horizontal portion 8 at the tip of the long piece, and a claw 11 for preventing removal is provided in the first horizontal portion 10 of the long piece.

On the other hand, the short piece 12 that is parallel to the horizontal part 8 of the long piece is provided with a winding collar part 5, and the side wall part 16 connecting the horizontal part 10 of the long piece and the short piece 12 is provided with a cutout part 14. has been established.

The coil terminal constructed in this manner is inserted and fixed into a terminal fixing portion 15 as shown in FIG. This terminal fixing part 15 is provided near the coil winding start part or the coil winding end part of the coil spool 1, and has a slit 16 that can hold the part other than the horizontal part 8 at the tip of the long piece of the coil terminal. It also has a claw 1 to prevent the coil terminal from being pulled out.
A locking hole 17 is drilled into which a locking hole 17 can be locked.

Therefore, when setting the coil terminal in the terminal fixing part 15, it is sufficient to insert the coil terminal laterally into the terminal fixing part 15 and engage the claw 11 for preventing the coil terminal from being removed in the locking hole 17. In this case, if the U-shaped shape of the coil terminal and the shape of the slit 16 of the terminal fixing part 15 are not completely matched, for example, the angle of the slit 16 of the long piece, the short piece, or both can be intentionally changed. Since elasticity acts when the coil terminal is inserted, it is possible to make the coil terminal stick more tightly.O The coil terminal inserted and fixed in the terminal fixing part 15 in this way has the notch part 14, so the terminal screw hole 9
When some kind of stress is applied to or around it, the stress can be absorbed and the stress is not transmitted to the winding collar portion 5.

The shape of this coil terminal fitted into the terminal fixing portion 15 is as shown in the plan view of FIG.

That is, if the wall 18 of the terminal fixing part 15 is made to protrude beyond the long horizontal portion 8 by two minutes, stress will not be applied to the long horizontal portion 8 when the coil spool 1 is housed in the nousing. Note that the shaded area in FIG. 3 shows a part of the housing body.

〔Effect of the invention〕

After the coil terminal of the present invention is inserted and fitted into the coil terminal, automatic winding, automatic winding, and soldering to the winding part can be performed, and the stress applied to the horizontal part of the long piece is absorbed by the cutout part. No stress is transmitted to the winding collar, so there is no risk of wire breakage. In addition, it does not require the relay terminals found in conventional products, making it less expensive, and the structure is such that no force is applied to the collar after it is assembled into the H casing, ensuring a reliable product that delivers a certain level of performance. This is a high coil terminal.
