Description

  The present invention relates to a method of manufacturing a conductive terminal device provided in a rotating electrical machine, a conductive terminal component, and a conductive terminal device.

In a rotating electrical machine having a rotating shaft and an armature, a brush for supplying electric power for rotating the armature is used.
The brush is normally stored in a brush holder, and the brush holder is fitted into the yoke housing opening.

The brush holder is provided with a conductive terminal component. One end of the conductive terminal component is connected to the brush, and the other end is connected to an external terminal connected to an external power source.
Since it is connected in this way, the electric power supplied from the external power source is transmitted from the conductive terminal component to the brush, and becomes a driving force for rotating the armature.

Generally, a conductive terminal component is formed by stamping a thin plate made of a single conductive member.
That is, it is formed by pressing a blank material made of a conductive member into a necessary shape (see FIG. 11).
The conductive terminal component used in this way is largely curved in a substantially U shape in order to avoid the armature in the brush holder (along the armature insertion hole formed in the brush holder).
For this reason, the structure becomes complicated, and as shown in FIG. 11, the number of conductive terminal parts pressed from one blank is limited, and there is a problem that the yield is poor.
According to the example shown in FIG. 11, the yield rate is about 15%.
In order to solve such problems, various techniques for efficiently producing conductive terminal parts have been developed (see Patent Document 1).

JP 2002-315256 A

Patent Document 1 discloses a conductive terminal device for a motor and a method for manufacturing the same.
The conductive terminal piece described in Patent Document 1 is punched out as one elongated plate, and a predetermined shape of the conductive terminal piece is formed by bending a predetermined portion of the punched elongated plate.

However, the conductive terminal piece described in Patent Document 1 has a structure in which the bent portions overlap.
For this reason, the thickness of the conductive terminal piece cannot be made constant.
In addition, since the overlapped portion is doubled, the material cost increases.

  An object of the present invention is to solve the above-mentioned problems, and it is possible to improve the material yield without increasing the material cost, and to provide a method for manufacturing a conductive terminal device with stable quality and a conductive terminal component, The present invention also provides a conductive terminal device.

The conductive terminal component is formed by punching and bending the cutout portion of the conductive terminal component prototype so as to be closed.
As described above, the conductive terminal component prototype is punched in a state where the bent portion is not completely bent, that is, in a state close to one elongated shape.
Therefore, the yield rate can be increased as compared with punching a shape having many bent portions.
Further, since the conductive terminal component is formed by bending the notched portion of the conductive terminal component prototype so as to be closed, the bent portion does not overlap and a conductive terminal component having a certain thickness is formed. be able to.
Further, since the notched portion of the conductive terminal component pattern is closed and bent, the bent portion as designed can be formed reliably and easily with a small force.
As described above, according to the conductive terminal component and the conductive terminal device including the conductive terminal component according to the present invention, it is possible to improve the yield rate and provide a product with stable quality.

At this time, in the second step, the fixing place other than the notch portion of the conductive terminal component is clamped and fixed by a first jig, and the notch portion is the first jig. It is preferable to perform bending in a loosely-fitted state that is separated by a predetermined interval because the bent portion can be formed efficiently, reliably and easily.

An upper support member, and the fixing location other than the cutout portion of the conductive terminal component is disposed on at least one of the upper surface side of the lower support member and the lower surface side of the upper support member. The spacer is interposed between the lower support member and the upper support member via the spacer, and the spacer is disposed on one of the upper surface side of the lower support member and the lower surface side of the upper support member. If the spacer is provided on both the upper surface side of the lower support member and the lower surface side of the upper support member, the thickness is equal to the thickness of the spacer. It is configured as a sum of the thicknesses of both the spacer.

Because of this structure, the fixing location other than the notch of the conductive terminal part is sandwiched between the lower support member and the upper support member via the spacer, and the notch is loosely fitted by the thickness of this spacer. It becomes a state.
Therefore, the notch can be bent efficiently and reliably.

  Further, at this time, the fixing place other than the notch portion of the conductive terminal component is clamped and fixed in a locking groove formed in the first jig, and the fixing place is connected to the notch portion. The opposite end portion is sandwiched by a conductive terminal sandwiching groove that sandwiches the end portion formed in the second jig, and the notched portion closes with the notched portion serving as a fulcrum. When it is configured to be formed by moving the end side by applying a force together with the second jig to the end side toward the direction, a bent portion can be formed efficiently, reliably and easily. This is preferable.

A connector having a connection terminal to be connected; and a conductive terminal component made of a conductive material, wherein the conductive terminal component is formed with at least one bent portion, and the bent portion is the bent portion.

FIG. 8 is an explanatory view showing an outline of a spacer arrangement state and a bending process, and FIG. 9 is a manufacturing process diagram of the conductive terminal device.
In addition, FIG. 10 is explanatory drawing which shows the modification of a bending apparatus.

With reference to FIG. 1, the configuration of a motor M as a rotating electrical machine according to the present embodiment will be described.
The motor M according to this embodiment includes a motor main body 2 and a brush holder 3.
The motor main body 2 according to this embodiment includes a yoke housing 4, a magnet 5, an armature 6, a rotating shaft 7, and a commutator 9.
The yoke housing 4 is a substantially cylindrical member with a bottom, covers an armature 6 described later, and stores it inside.

The magnet 5 is a permanent magnet attached to the inner wall surface of the yoke housing 4 and supplies a magnetic force that serves as a rotational driving force for the armature 6 described later.
The armature 6 is a rotating body formed by laminating a plurality of thin plates, and a winding is turned on the surface thereof. The electromagnetic force generated by energizing the winding and the magnetic force of the magnet 5 are mutually connected. Rotate by action.

The rotating shaft 7 is a rotating shaft of the armature 6, and one end side (the bottom surface side of the yoke housing 4) is rotatably supported by the bearing 8.
The other end side (output side) is also rotatably supported by the bearing 8.
The commutator 9 is an electrode that makes contact with the brush 16 fed from an external power source and performs rectification, and is disposed on the output side of the armature 6.

The brush holder 3 is fitted into the opening 4 a of the yoke housing 4.
The brush holder 3 includes a resin end housing 11 that covers the opening 4 a of the yoke housing 4 and is integrally configured.
The end housing 11 includes a housing body 11a that is fitted into the opening 4a of the yoke housing 4 and a connector 11b that extends radially outward from the housing body 11a.

The conductive terminal component 31 according to the present embodiment is disposed in the brush holder 3, and one side is electrically connected to the brush 16, and the other side is electrically connected to the connector 11b connected to the external power source. .
As described above, the external power is supplied to the brush 16 through the conductive terminal component 31.
The brush holder 3, the connector 11 b, the brush 16, and the conductive terminal component 31 integrally form an electric circuit that supplies power to the armature 6 from an external power source, thereby forming a conductive terminal device T.

The punching state of the conductive terminal component 31 will be described with reference to FIG.
In this embodiment, the conductive terminal component 31 to be manufactured is finally formed in the same shape as the conductive terminal component 131 shown in FIG.
In general, a bent portion such as part A shown in FIG. 11 has a very low yield rate.
For this reason, the conductive terminal component 31 according to the present embodiment is originally in a state where the curvature of the bent portion (see A portion in FIG. 11) is lowered as shown in FIG. ).
What is punched in this way corresponds to the “conductive terminal prototype”.

Thus, if the primitive punching shape is changed so that the bent portion is in a state close to a straight line, the yield rate is improved.
That is, in the case of punching in the state of FIG. 11, the yield rate is improved to about 30% in the case of punching in the state of FIG. 2, compared to the yield rate of about 15%.
Thus, by changing the primitive punching shape, the material yield rate is dramatically improved.

The primitive punching shape of the conductive terminal component 31 (corresponding to the “conductive terminal prototype”) is formed with a slit-shaped recess 31a on the inner corner side of the bending point, as shown in FIG. Opposite protruding corner sides are formed as convex portions 31b.
Such a bending point is referred to as “bending point 31A”.

Next, the bent portion will be described with reference to FIGS. 3 and 4.
As shown in FIG. 3, the bending point 31 </ b> A is formed with a concave portion 31 a in a portion that becomes an inner corner when the bending point 31 </ b> A is bent to prevent the member from overlapping.
In addition, a convex portion 31b whose outer periphery is formed in a substantially arc shape is formed in a portion that faces the concave portion 31a and becomes a corner when bent.

When the tip H1 is fixed in this state and a force is applied in the B direction, the gap of the recess 31a is closed and the bending point 31A is easily bent.
The state after being bent in this way is shown in FIG.
When the same operation is repeated or the same operation is repeated with the opposite end H2 being the opposite end fixed, the conductive terminal component 31 bent into a substantially U-shape is formed.
As shown in FIG. 4, by performing such processing, the gap of the recess 31a is closed, and the bending point 31A is bent by the angle of the original recess 31a.

FIG. 5 shows details of the bent portion.
As shown in FIG. 5, the recess 31a is formed as a slit cut out in a substantially isosceles triangle shape having an apex angle α °.
Further, the convex portion 31b is formed as a convex portion having a substantially arc-shaped outer periphery, and is disposed to face the concave portion 31a.
Since it is configured in this way, the bending point 31A is bent while closing the gap with the vicinity of the apex angle of the recess 31a as the bending center point (hereinafter referred to as “center point O”).

Thus, if the recess 31a is formed in a substantially isosceles triangle shape with the center point O as the apex angle α °, the recess 31a is fixed by applying a force in the D direction by fixing one side (point C side). The center point O is easily closed, and the bending point 31A is easily bent.
Therefore, the predetermined shape can be easily formed.
In the present embodiment, the apex angle α ° is formed to be about 45 °, but is not limited to this, and the apex angle α ° is appropriately set according to the shape of the finished conductive terminal component 31. It is to be decided.

The bending method will be described in detail with reference to FIGS.
In addition, the primitive shape of the conductive terminal component 31 is punched from the blank material by a known method using a known punching device.
The bending apparatus S according to the present embodiment will be described with reference to FIG.

The bending apparatus S according to the present embodiment is formed to include a first jig S1 and a second jig S2.
1st jig | tool S1 which concerns on this embodiment is a member for fixing the one end part of the conductive terminal component 31, and has the lower support member S11 and the upper support member S12, and is comprised.
The lower support member S11 and the upper support member S12 are substantially rectangular parallelepiped members, and are used in a stacked state.

In the present embodiment, spacers P and P are formed on the surfaces of the lower support member S11 and the upper support member S12 (the surface facing the upper side of the lower support member S11 and the surface facing the lower side of the upper support member S12). Each is arranged.
One end of the conductive terminal component 31 is sandwiched between the portions where the spacers P and P are disposed.
The spacers P and P may be integrally formed with the lower support member S11 and the upper support member S12.

The second jig S2 according to the present embodiment is a substantially rectangular member having a substantially rectangular conductive terminal holding groove S22 cut out at one end.
The width of the conductive terminal clamping groove S22 is formed to be substantially the same as the width of the conductive terminal component 31, and the other end side (the end portion on the side not fixed to the first jig S1) of the conductive terminal component 31 is It is configured to be able to be held in the conductive terminal holding groove S22.

  The bending point 31A of the conductive terminal component 31 is sandwiched between one end of the punched primitive conductive terminal component 31 by spacers P and P formed on the lower support member S11 and the upper support member S12 of the first jig S1. The other end side is fixed by the second jig S2, and the second jig S2 is bent easily by applying a force in the E direction.

The spacers P, P of the first jig S1 will be described with reference to FIG.
As shown in FIG. 7, one end portion side of the conductive terminal component 31 is sandwiched between spacers P and P formed on the lower support member S11 and the upper support member S12.
At this time, if the thickness of the conductive terminal component 31 is K1 and the thickness of the spacer P is K2, the gap between the lower support member S11 and the upper support member S12 is K1 + 2 × K2, but this is 2 × K2 minutes. Is a movement margin on the other end side of the conductive terminal component 31.
That is, the predetermined interval for forming the “free fitting state” of the bending point 31A is 2 × K2 in the present embodiment.
When the spacer P is provided only on one side, the predetermined interval is K2.

Further, when the bending point 31A is bent, the vicinity of the bending point 31A tends to bulge in the vertical direction because of a force physically applied, but the bending is caused by the presence of the lower support member S11 and the upper support member S12. The swelling of the point 31A is suppressed.
That is, there is only room for the thickness of the spacers P (ie, K2) in the vertical direction.
For this reason, a stable high quality product can be provided.
In the present embodiment, the thickness of the spacer P is set to 0.1 mm. However, the thickness is not limited to this, and the thickness of the spacer P is appropriately determined according to various circumstances.

For this reason, as shown in FIG. 8, when the other end side of the conductive terminal component 31 is clamped in the conductive terminal clamping groove S22 of the second jig S2, and a force is applied in the F direction, the bending point of the conductive terminal component 31 is obtained. 31A bends easily in the same direction.
Further, in the present embodiment, the spacers P, P are disposed in an oblique direction from the substantial center vicinity of the lower support member S11 and the upper support member S12 toward one vertex.
This is to ensure a moving range when the other end of the conductive terminal component 31 is moved.
That is, when the other end portion of the conductive terminal component 31 is moved, the lower support member S11 and the upper support member S12 are prevented from contacting the conductive terminal component 31 or the second jig S2.

In the present embodiment, the second jig S2 is used so that the bending process can be easily performed with a small force using the principle of the lever. However, the second jig S2 is not necessarily used. There is no.
In addition, the installation location and number of spacers P, the arrangement direction and arrangement position of the conductive terminal component 31 are examples, and one end is fixed and the other end is bent around the bending point 31A. Any configuration may be used as long as it can be moved for the purpose.

The conductive terminal component 31 thus formed is mounted on the brush holder 3 and electrically connected to the brush 16 on one side and to the connector 11b connected to the external power source on the other side. A terminal device T is formed.
Although illustration is omitted, the brush holder 3 itself is a known holder, and two disposition grooves for disposing the two conductive terminal parts 31 are formed.
The two conductive terminal parts 31 are arranged in the two arrangement grooves, and are electrically connected to the respective parts such as the brush 16 and the connector 11b by connection or the like.
Thus, the external power supply is configured to be supplied to the brush 16 via the conductive terminal component 31.

  That is, as shown in FIG. 9, the conductive terminal device T according to the present embodiment firstly performs a first step (punching) of punching the primitive shape (corresponding to “conductive terminal prototype”) of the conductive terminal component 31 from the blank material. Step), a second step (bending step) of bending the bending point 31A of the conductive terminal component 31 having a primitive shape, and the conductive terminal component 31 bent and formed into a predetermined shape is assembled to the brush holder 3 to form a conductive terminal. It is manufactured by the third step (assembly step) for completing the device T.

Next, a modification example will be described with reference to FIG.
In this modified example, the structure of the first jig S1 is different.
The first jig S1 ′ according to the modified example includes a lower support member S11 ′ and an upper support member S12 ′.
The upper support member S12 ′ according to this example is formed in the same shape as the lower support member S11 ′, and covers the lower support member S11 ′.

The lower support member S11 ′ according to this example is formed with a locking groove L1 for locking one end portion side of the conductive terminal component 31.
The depth of the locking groove L <b> 1 is formed substantially the same as the thickness of the conductive terminal component 31, and the shape thereof is formed to match the shape of the end portion of the conductive terminal component 31.

In addition, a bent groove L2 having a shape in which one side is cut out into a substantially rectangular shape is formed in the lower support member S11 ′ continuously with the locking groove L1.
On one side (the center side of the lower support member S11 ′) of the bent groove L2 and the engaging groove L1, a convex relief groove L21 cut out in a substantially fan shape is formed.
When the bending point 31A is bent, the protruding portion relief groove L21 absorbs the spreading allowance of the protruding portion 31b spreading outward.

Further, since the bending groove L2 is cut out on one side of the lower support member S11 ′, movement of the conductive terminal component 31 and the second jig S2 is not hindered when the bending process is performed.
As described above, in the modified example, the conductive terminal component 31 locked to the second jig S2 by locking one end of the conductive terminal component 31 to the locking groove L1 formed in the lower support member S11 ′. By applying a force in the G direction to the other end of the bent portion 31A, the bent portion 31A is easily bent.
Note that the distal end side of the second jig S2 is held at a position not related to the bent portion 31A.

  As described above, in the conductive terminal device T, the conductive terminal component 31 and the manufacturing method thereof according to the present embodiment, a high yield rate can be ensured and the punched-out primitive shape conductive terminal component 31 is bent. It can be easily bent from the point 31A, can prevent the occurrence of non-uniform thickness, and can provide a high-quality product.
