Description

Electrical / electronic device connection members and their manufacturing methods, as well as coils and electrical / electronic devices

The present invention relates to an electric / electronic device connecting member, a method for manufacturing the same, and a coil and an electric / electronic device.

Examples of the member used for the electric / electronic device (member for the electric / electronic device) include a conductor (for example, a conductor, a terminal, and a bus burring of an insulated electric wire material) when manufacturing the member and mounting the member on the electric / electronic device. .) They are electrically joined together.
As a method for joining members for electrical / electronic equipment, an appropriate method is applied according to the member to be joined, the mounting position on electrical / electronic equipment, etc. For example, a method of abutting conductors with each other and joining (welding) conductors with each other. Examples include a method of arranging and joining (welding) face-to-face. Above all, in order to contribute to the miniaturization of electrical and electronic equipment and the improvement of the strength of the joint, the conductors are joined by arranging them in the vicinity where they can be welded, usually facing each other (whether in contact (overlap) or non-contact). , Preferably a welding method is often used.
Conventionally, in the method of arranging and welding the conductors facing each other, usually, the conductors are directly welded after holding the facing arrangement state by a holding mechanism so that the facing arrangement state is not impaired before or during welding. Such a welding method is described in, for example, Patent Document 1.

Japanese Unexamined Patent Publication No. 2000-350422

In the above-mentioned conventional welding method, the thermal energy applied during welding propagates to the holding mechanism that holds the conductors. Therefore, in order to weld the conductors to the desired welding state, the applied thermal energy is applied. It is necessary to apply more energy than required for welding. Therefore, when welding a member for electric / electronic equipment having a resin member such as an insulated electric wire material, the excessively applied heat energy deteriorates the resin member (insulating coating layer of the insulated electric wire material) propagated through the conductor. Further, if the resin member remains in the welded portion, there arises a problem that a blow hole or the like is generated. The occurrence of blow holes causes a decrease in welding strength and an increase in electrical resistance. Therefore, in the normal welding method, in order to avoid the above problem, the facing area and the normal facing length (welding allowance, and as a result, the welding region) of the conductors to be arranged facing each other are increased to reach the resin member of thermal energy. It suppresses propagation.
However, in recent years, the miniaturization and high performance of electrical and electronic equipment have been rapidly progressing, and the conventional welding method that requires a large welding allowance cannot sufficiently cope with the progress.

The present invention provides an electrical / electronic device connection member and a manufacturing method thereof, which can join conductors to each other with high strength and low resistance, and can meet the demands for miniaturization and high performance of electrical / electronic devices. The challenge is to provide. Another object of the present invention is to provide a coil using the electric / electronic device connecting member and an electric / electronic device using the coil.

In the method of joining conductors arranged facing each other by welding, the present inventors do not directly weld the conductors to each other, but connect members to the ends of the conductors arranged facing each other (also referred to as conductor ends). Is attached, and the conductor end portion is welded together with the connecting member in a state where the positional deviation of the facing arrangement state at the conductor end is constrained by the positional deviation restraining portion of the connecting member (the facing arrangement state is fixed). It has been found that it is possible to weld (join) each other, and further, the end of the conductor and the connecting member with high welding strength while suppressing an increase in electrical resistance. Further, the joining method is not limited to welding, and even if the joining method uses a conductive adhesive or the like, by using the above-mentioned connecting member, the positional deviation in the face-to-face arrangement state can be restrained, and the desired joining is possible. I found that Moreover, by attaching a connecting member and restraining the end of the conductor, it is possible to eliminate the need for a holding mechanism that is essential for conventional welding methods and welding equipment, or to adopt a joining method using a conductive adhesive or the like. By doing so, even if the above problem due to the use of the holding mechanism is solved and the joining allowance (welding allowance) is narrowed or shortened (hereinafter, simply referred to as narrowing) according to the required level, the desired joining is achieved. It was found that the state (high strength and low resistance) can be realized.

[[Electrical / electronic device connection member]]
The electrical / electronic device connecting member (also referred to as a connecting member for electrical / electronic equipment) of the present invention is displaced between the conductor end portion of the electrical / electronic device member arranged face-to-face and the facing arrangement state at the conductor end portion. It is formed by joining with a connecting member having a restraining portion. The electrical / electronic device connecting member may be any member as long as it is a member in which the electrical / electronic device members are joined by the conductor ends and the connecting members arranged facing each other, and it does not matter whether or not the member is mounted on the electrical / electronic device. That is, the electrical / electronic device connecting member of the present invention includes not only the members joined before mounting on the electrical / electronic device but also the members joined in the mounting process or after mounting on the electrical / electronic device. Include.
The electrical / electronic device connecting member of the present invention may be a long member (insulated electric wire material), but is preferably a short member having a predetermined length. The length (total length) of the short-shaped member is appropriately set according to the application and the like, but can be, for example, 10 to 100 cm. Such a short member is preferably used as an insulating electric wire material for mounting a coil of a rotary electric machine.
In the electrical / electronic device connecting member of the present invention, for example, the connecting member has a restraining portion on the inner surface that restrains the facing arrangement state of the conductor end portion, and preferably the conductor (end portion) is locked with the restraining portion (the end portion). It can also be said to be an electrical / electronic device connecting member having a restrained portion (engaged and screwed) on the outer surface, for example. Further, it can be said that the conductors of the electric / electronic device member are joined by the connecting member by using the connecting member having the position deviation restraining portion.

In the present invention, the member for an electric / electronic device means a member used (mounted) in the electric / electronic device and electrically joined to another member or the like. For example, wiring materials such as insulated electric wire materials, terminals, bus bars, bus burring, motor / generator connections, and the like can be mentioned.
Therefore, the electric / electronic device connecting member of the present invention may be a member in which one or a plurality of members for electric / electronic devices are joined, and a member in which a plurality of wiring materials are joined to each other, a wiring material and a terminal, or a member. It includes a member to which a bus burring is joined, and further, a member to which a plurality of wirings and joint parts are connected.

In the present invention, the misaligned restraint portion (sometimes referred to simply as the restraint portion) does not cause a relative misalignment (does not fluctuate) so that the conductor end portions (the conductor end portions are arranged facing each other) arranged facing each other do not cause a relative misalignment. It means a structural part that can hold or support (hold) conductor ends with each other in a state of being restrained (regulated), and is also called a restraining mechanism. This misalignment restraint is the position of the conductor end in the direction intersecting the axis of the conductor end and / or the position of the conductor end in the axial direction of the conductor end in the face-to-face arrangement state of the conductor end. By restraining the deviation, the conductor ends arranged facing each other are fixed in a predetermined facing arrangement state. The restraint portion that restrains the misalignment of the conductor end in the axial direction of the conductor end is in contact with the end (end face) of the conductor end arranged facing each other and regulates the misalignment movement in the same direction, and the conductor end The restraint portion that restrains the positional deviation of the conductor end portion in the direction intersecting the axis of the above is in contact with the end portion (side surface) of the conductor end portion arranged facing each other and regulates the positional deviation in the same direction.
In the present invention, the means of arranging the conductor ends face-to-face means both a mode in which a plurality of conductor ends are arranged facing each other at a distance capable of joining and a mode in which the conductor ends are arranged in contact with each other. Include. The distance that can be joined varies depending on the size of the conductor (conductor end), the joining method, and the like, and is not unique. However, the distance between the conductor ends arranged facing each other is, for example, about 0.5 mm. The method of arranging the conductor ends face-to-face is not particularly limited, and the arrangement state, shape, etc. of the conductors can be appropriately changed. Examples thereof include a method of arranging at least the vicinity of the edge in a facing state, a method of using these in combination, and the like. The “face-to-face arrangement” means that the conductor ends may be arranged in a state where they can be joined, and a state in which the conductor ends are arranged side by side is preferable. The face-to-face arrangement is performed by appropriately setting, for example, the separation distance of the conductor end portions, the face-to-face area, the position in the axial direction (end face height), and the like. For example, the facing area of the conductor end portions to be arranged facing each other is appropriately determined according to the degree of miniaturization, high performance, etc. of the electric / electronic device, the size of the conductor itself, the welding method, or the conditions. It is preferably 250 mm ² , more preferably 60 to 20 mm ^2.
In the present invention, the conductor ends arranged facing each other may be both conductor ends of the same (one or one) electric / electronic device member, but may be different (plural) electric / electronic device members. It is preferable that the ends of the conductors are connected to each other.

In the present invention, in addition to welding (butt welding, lap welding, spot welding, etc.), joining includes bonding using a conductive adhesive, a conductive adhesive sheet, etc. Welding is preferred and laser welding is more preferred in terms of electrical resistance.
In the present invention, joining means joining with the ends of the conductors to be joined in contact with each other, separated from each other, and further via other members or the like. However, the contacted state includes an aspect through a plating layer made of various metals formed on the surface of the member to be melted in order to improve weldability.
In the present invention, when a member for electrical / electronic equipment and a member for connection are joined by welding, a welded portion is formed. The welded portion includes a portion where the materials of the conductor and the connecting member are melt-mixed (alloyed, solidified, etc.) with each other, a portion having welding marks, a portion having increased strength after welding, and the like. The welded portion means to include the through-welded portion, and is preferably a through-welded portion. Here, the penetration welded portion means a welded portion formed by penetrating at least a part of the welded portion in the thickness direction (from the laser irradiation surface to the back surface side thereof).

[Connecting member]
The connecting member used in the present invention has a restraining portion for restraining a positional deviation in a facing-to-face arrangement state at the end portions of conductors arranged to face each other. Before joining, this connecting member is usually attached to the outside of the conductor end so as to surround the conductor end, and then is joined to the conductor end by a joining step. At this time, the connecting member restrains the positional deviation of the conductor end portion in the face-to-face arrangement state before and during the joining from the outside of the conductor end portion, and restrains the face-to-face arrangement state (constrained state) even after the joining.
The electric / electronic device connecting member of the present invention has a narrow or short joining allowance (welding allowance) that cannot be realized by the connecting member obtained by the conventional welding method. It is joined in the desired joining state (high strength and low resistance). This connecting member may or may not change depending on the joining method, and in the welding method, at least a part thereof melts to form a welded portion together with the conductor. The following peripheral walls of the connecting member described later may or may not be welded. When a plating layer such as a tin layer is formed on a connecting member or a conductor end, the welded portion contains a plating layer forming element such as tin (element) and is alloyed or solid-dissolved with a conductor forming material such as copper. To do.
The positional deviation of the conductor end portion constrained by the connecting member in the facing-to-face arrangement state includes the positional deviation of the conductor end portion in the direction intersecting the axis of the conductor end portion, and preferably the conductor end in the axial direction of the conductor end portion. Includes a misalignment of the part, more preferably both misalignments. Here, the positional deviation of the conductor end portions in the direction intersecting the axial direction of the conductor includes a positional deviation in which the facing distance between the conductor end portions increases (separates in the overlapping direction), and preferably the conductor end portions overlap each other. Includes a changing position (in the direction of intersection in the overlapping direction), more preferably both positions.

The connection member has the above-mentioned misalignment restraint function due to the restraint portion provided on the connection member. The connecting member may independently serve as a misalignment restraint portion, or may be provided with a misalignment restraint portion. When the connecting member itself also serves as a misalignment restraining portion, details will be described later. For example, a gap portion (bottomed hole) for accommodating a conductor end portion provided in the connecting member functions as a misalignment restraining portion. Aspects are mentioned. On the other hand, the misaligned restraint portion attached to the connecting member is preferably provided on the connecting member corresponding to the confined portion provided at the end of the conductor, and the misaligned restraining portion attached to the connecting member is preferably provided. The misalignment restraint function may be shown in cooperation with the restraint portion.

The shape and dimensions of the connecting member used in the present invention are appropriately determined as long as the member has the above-mentioned misalignment restraining portion and can restrain the misalignment of the conductor end portion. A lid shape (cap shape) having a gap portion for accommodating the conductor end portions arranged facing each other is preferable. Specifically, a shape (lid shape) having a joining base portion to be joined to the conductor end portion and a hem portion extending in the axial direction from the end edge of the joining base portion along the side surface of the conductor end portion can be mentioned. ..

The joining base has a function of joining the conductor ends to each other. When the connecting member itself also serves as a misalignment restraint portion, the joint base portion has a misalignment restraint function, while when a misalignment restraint portion is provided separately, the joint base portion does not have to have a misalignment restraint function. However, it is preferable to have it. The misalignment restraint function of the joint base restrains the movement (positional misalignment) of the conductor end in the axial direction by contacting the bottom surface with the conductor end (end face), preferably both conductor ends. By touching the side surface of the portion, the movement (positional deviation) of the conductor end portion in the direction intersecting the axial direction of the conductor end portion is restrained.
The shape of the joining base is not particularly limited as long as it has at least a function of joining the conductor ends to each other, and examples thereof include a shape having a surface in contact with the end face of the conductor ends. When the joint base further has a misalignment restraining function, the joint base is preferably set to a shape corresponding to the outer shape of the conductor ends arranged facing each other. The specific shape of the joint base will be described in detail later with reference to the drawings, and examples thereof include a convex shape such as a substantially V shape or a substantially U shape, a frustum shape, or a flat plate shape.
The thickness of the joining base is set to a thickness that allows joining, and is appropriately set according to the welding method or conditions, the material of the joining base, and the like. For example, when welding, it can be 0.1 to 10 mm. When welding, the thickness of the joint base means the shortest distance from the welding start point to the end of the conductor, and does not necessarily match the thickness of the joint base itself. For example, when the laser is irradiated from the direction along the axial direction of the conductor, it means the thickness along the laser irradiation direction and coincides with the thickness in the direction along the axial direction of the conductor.

The hem portion constituting the connecting member has a misalignment restraint function when the connecting member itself also serves as a misalignment restraint portion, while the hem portion has a misalignment restraint function when the misalignment restraint portion is separately provided. It does not have to be, but it is preferable to have it. The position deviation restraint function of the hem restrains the movement (positional deviation) of the conductor end in the direction intersecting the axial direction of the conductor end by contacting the inner peripheral surface with the side surface of the conductor end. Further, the movement of the conductor end portion in the axial direction is restrained (for example, by frictional force).
The hem is preferably a wall-shaped portion that hangs down from the edge of the joint base, and may be a peripheral wall that goes around along the edge of the joint base, and is a leg wall provided at intervals at the edge of the joint base. There may be.

The misaligned restraint portion attached to the connecting member is not particularly limited as long as it performs the misalignment restraint function, but is locked (including engagement, screwing, etc.) with the restrained portion provided at the end of the conductor. Therefore, a structure capable of restraining the facing arrangement state of the conductor end portions is preferable. Positional deviation By locking the restrained portion and the restrained portion, the positional deviation in the face-to-face arrangement state can be effectively restrained, and the restrained state is maintained unless the locking is released. The position deviation restraining portion and the restrained portion are not particularly limited as long as they have a structure in which the positioning deviation of the conductor end portion can be constrained by locking the two, and includes, for example, a convex portion (protruding portion, step portion, etc.). ) And recesses (including steps). The misalignment restraint portion and the conductor end portion may have either a convex portion or a concave portion, and may have both. As a combination of the misaligned restraint portion and the confined portion, for example, an inner protruding portion as a misaligned restraint portion provided on the inner peripheral surface of the hem portion of the connecting member (for example,

reference numeral

32 or 34 in FIGS. 4 and 5). And a flange (for example, reference numeral 31 in FIG. 4) or a groove portion (for example, reference numeral 33 in FIG. 5) as a restrained portion provided on the side surface of the conductor end portion, and provided on the inner peripheral surface of the hem portion of the connecting member. The combination of the rough surface as the provided misalignment restraint and the rough surface as the confined portion provided on the side surface of the conductor end, and the misalignment restraint provided on the inner peripheral surface of the hem of the connecting member. A combination of, for example, a thread-like unevenness as a portion (for example, reference numeral 36 in FIG. 6) and, for example, a screw groove-like unevenness as a restrained portion provided on the side surface of the conductor end portion (for example, reference numeral 35 in FIG. 6). And so on.

The above-mentioned connecting member has been described as a connecting member having an integral structure having a joining base portion and a hem portion, but in the present invention, the connecting member is not limited to the one having an integral structure. For example, as shown in FIG. 7, a connecting member including the above-mentioned joining base portion (which does not have a hem portion) and an annular member which is configured as a separate body from the joining base portion and corresponds to the hem portion can be mentioned. .. The inner shape and inner dimension (inner diameter) of the annular member are the same as the outer diameter and outer diameter (outer diameter) of the conductor ends arranged facing each other. Further, the inner surface of the annular member may have the above-mentioned non-restraint portion.

The connecting member is made of a material that can be joined to the conductor, and is usually made of various metals. It is preferably made of a weldable metal, more preferably made of the same material as the conductor. For example, it is more preferable that all of them are formed of the above-mentioned high-purity copper (oxygen-free copper or oxygen-free copper for electron tubes). Thereby, the welding strength can be increased. Further, since it is possible to suppress the generation of blow holes (spherical cavities or pores) due to the oxygen content and the resin member during welding, the electrical resistance of the welded portion can be lowered. Further, by forming the connecting member with the same material as the conductor, there is no difference in melting point between the conductor and the connecting member at the time of welding, and it is possible to weld firmly to any of them.

When joining is performed by welding, at least one of the end faces of the connecting member and the conductor end is welded to at least the surface to be welded (the end face of the conductor end, the surface of the connecting member in contact with the end face). It is preferable to have a layer (not shown) containing a material for improving the above. As such a material, for example, when the connecting member and the conductor are formed of copper or a copper alloy, tin is preferably mentioned.
The tin layer may not form a layer as long as tin is present on the surface to be welded, but it is preferably a tin-plated layer. The tin layer preferably has a thickness of 0.1 to 5 μm, more preferably 0.3 to 3 μm, from the viewpoint of improving the tensile strength. By setting the thickness of the tin layer within the above range, it is possible to have good tensile strength. On the other hand, if the tin layer is attached too thick, segregation is likely to occur at the molten portion, which becomes the starting point of cracks, and as a result, the tensile strength decreases.

[Members for electrical and electronic equipment]
As the member for electric / electronic equipment, as described above, an insulated electric wire material is preferable. The details will be described later.
At least the ends of the conductors of the members for electrical and electronic devices are arranged facing each other regardless of the cross-sectional shape, as will be described later. The mode of the face-to-face arrangement is not particularly limited and is appropriately determined according to the application and the like, but at least the conductor ends may be arranged so as to face each other and are aligned in the axial direction (parallel to the axial direction). It may be an arrangement. In the present invention, it is preferable that the lengths facing in parallel can be shortened (the joint allowance can be narrowed) even if they are arranged in parallel in the axial direction. The number of members for electrical / electronic devices arranged facing each other is appropriately set according to the application and the like, and is not particularly limited. For example, the number may be 2 to 6, preferably 2 or 3.
3 to 7 are views showing a cross section of each electric / electronic device joining member as viewed from the same direction as in FIG.

[Preferable form of electrical / electronic device connecting member]
Hereinafter, preferable forms of the electrical / electronic device connecting member will be specifically described with reference to the drawings.
All of the following electrical / electronic device connecting members appropriately emit laser light emitted from the outside of the connecting member along the axial direction of the conductor end (from above the connecting member toward the conductor end). The end face of the conductor end is irradiated while being swept (scanned) in the direction perpendicular to the axial direction via the connecting member, and at least a part of the end face of the conductor end is welded to the connecting member. As will be described later, these electric / electronic device connecting members have a narrow or short welding allowance that cannot be realized by the connecting member obtained by the conventional welding method, and the electric / electronic device member and the connecting member can be connected to each other. It is joined in the desired joining state (high strength and low resistance).

1 and 2 show an example of a preferred embodiment of the electrical / electronic device connecting member of the present invention. FIG. 1 is a schematic front view showing the vicinity of the joint portion of the conductor end portion, and FIG. 2 is a schematic view showing a cross section taken along the line AA in FIG. 1 and showing a joint state between the conductor end portion and the connecting member. It is a sectional view.
The electrical / electronic device connecting member 1 includes a connecting member 20A that also serves as a misalignment restraining portion by itself. Specifically, the electrical / electronic device connecting member 1 has two flat insulated electric wire materials 10A and a connecting member 20A, and the end portion of the insulating electric wire material 10A and the connecting member 20A are connected to each other. It is welded (integrally), and two insulated wire members 10A are welded (electrically connected) to each other via a connecting member 20A.
In the insulated wire material 10A, the conductor insulating layer (not shown in FIGS. 1 and 2) and the outer peripheral insulating layer 14 in the vicinity of the end of the single-core conductor 16 are removed (peeled) in advance, and the ends thereof are removed. It is bent by bending, and the vicinity of the conductor ends are arranged facing each other. As shown in FIG. 2, the ends of the single-core conductor 16 are separated from each other when viewed from a direction perpendicular to the facing direction (overlapping direction), but may be in contact with each other in the present invention.
A connecting member 20A is attached and joined to the outside of the two conductor end portions arranged so as to face each other so as to normally surround (surround) the conductor end portions. The details of the connecting member are as described above, but the connecting member 20A has a prismatic block shape as shown in FIGS. 1 and 2, and has a bottomed hole (recessed portion) along the axis thereof. Has 21. The bottomed hole 21 has a bottom portion 22a corresponding to the above-mentioned joint base portion and a peripheral wall (corresponding to the above-mentioned hem portion) 23a that hangs down from the edge of the bottom portion 22a and is continuous in the circumferential direction, and faces each other. It has a shape and dimensions corresponding to the ends of the arranged single-core conductor 16. In the electrical / electronic device connecting member 1, although the welded portion is not clearly shown in FIGS. 1 and 2, the bottom portion 22a and the ends of both conductors (through) are welded. The peripheral wall 23a may or may not be welded to the end of the conductor.
The connecting member 20A is attached to the conductor end portions arranged facing each other, and the conductor end portion is housed in the bottomed hole 21. As a result, before and during welding, the bottom surface of the bottomed hole 21 comes into contact with both conductor end portions (end faces), and the inner peripheral surface of the peripheral wall 23a comes into contact with (closely) the side surfaces of both conductor end portions. It regulates the facing arrangement of conductor ends and restrains the positional deviation of each conductor end in the axial direction. Further, since the inner peripheral surface of the peripheral wall 23a is in contact with the side surfaces of both conductor end portions, the facing arrangement state of the conductor end portions is regulated, and the facing distance between the conductor end portions is widened (left-right direction in FIG. 2). (To) and the overlap between the conductor ends are changed (to a direction other than the vertical direction in FIG. 1). By mounting the connecting member 20A on the conductor end portion in this way, the facing arrangement state of the conductor end portion can be constrained (maintained) and joined without using the holding mechanism described above. Further, even after welding, the facing arrangement state of the conductor end portion can be restrained and maintained in the same manner. Therefore, in the electric / electronic device connecting member 1, even if the welding allowance is narrowed, two insulated wire materials are joined in a predetermined face-to-face arrangement state with high strength and low resistance.

[Manufacturing Method of Electrical / Electronic Device Connecting Member of the Present Invention]
In the electrical / electronic device connecting member of the present invention, a connecting member having a misalignment restraint portion of the conductor end portion is attached to a conductor end portion arranged facing each other of the electrical / electronic device member, and then the conductor end portion. It can be manufactured by a method of joining a connecting member and a connecting member. By this method of manufacturing the electrical / electronic device connecting member (referred to as the manufacturing method of the present invention), the facing arrangement of the conductor ends can be fixed at the time of joining or during joining, so that the conductors arranged facing each other of the members for electrical / electronic devices can be fixed. Even if the joining allowance at the end is narrowed, the conductors can be joined with high strength and low resistance. Further, since the joining allowance can be narrowed, the manufactured electric / electronic device connecting member can contribute to the miniaturization and high performance of the mounted electric / electronic device. Furthermore, if a welding method, particularly high-power fiber laser welding, is adopted as the joining method, the welding allowance can be further narrowed while suppressing deterioration of the insulating layer such as the insulated wire material, and the strength and low resistance are high. It is possible to further reduce the size and improve the performance of electrical and electronic equipment while achieving both standards.

In the manufacturing method of the present invention, first, a member for electrical / electronic equipment and a member for connection are prepared or manufactured.
The members for electrical and electronic devices and the members for connection used in the manufacturing method of the present invention are as described above. The connecting member can be manufactured by using the above-mentioned materials by a usual manufacturing method of a metal member, for example, a method of casting a molten metal into a mold having a predetermined size, turning, polishing, cutting, or the like.
When an insulated electric wire material is welded as a member for an electric / electronic device, it is preferable to remove the outer peripheral insulating layer (stripping (peeling removal)) at the end portion thereof. As a result, it is possible to suppress a decrease in welding strength and an increase in electrical resistance due to the generation of soot, blow holes, etc. during welding. The stripping method of the insulated wire material can be applied without any particular limitation to the usual method. When welding an insulated wire material having a multi-core conductor, the conductor insulating layer between the divided conductors in the multi-core conductor is usually not peeled off and remains, so it is preferable to apply the fiber laser welding method described later.

In the manufacturing method of the present invention, a connecting member having a misalignment restraint portion of the conductor end portion is attached to the conductor end portions of the electric / electronic device members arranged facing each other.
The prepared members for electrical and electronic equipment (for example, an insulated electric wire material) are arranged so that the ends of the conductors face each other as described above. Next, the connecting member is attached to the end of the conductor arranged facing each other. The connecting member is appropriately attached according to the facing arrangement of the conductor ends and the connecting member. The mounting of the connecting member constrains the facing arrangement of the conductor ends.
In the manufacturing method of the present invention, the facing arrangement of the conductor ends and / or the mounting of the connecting member to the conductor ends may be performed before or after mounting on the electric / electronic device. ..

In the manufacturing method of the present invention, the connecting member attached to the conductor end is then joined to the conductor end.
The joining of the conductor end and the connecting member can be applied without particular limitation to the usual methods. For example, various commonly used conductive adhesives, bonding methods using conductive adhesive sheets, and various welding methods. Can be mentioned. Of these, the welding method is preferable because it is excellent in joint strength and the like. Examples of the welding method include TIG welding (Tungsten Insert Gas welding), which is a fiber capable of irradiating a laser in a narrow width of about 20 μm for TIG welding in which the energy density of the laser is high and the welded portion requires about 20 mm. Laser welding is preferred. This fiber laser welding method can burn off the resin or the like forming the resin member (conductor insulating layer or outer peripheral insulating layer in the case of insulated wire material) of the member for electric / electronic equipment by high energy density at the time of welding. It is possible to avoid the occurrence of problems (decrease in welding strength, etc.) due to soot and blow holes that occur during welding and remain. Further, in the fiber laser, the processing time can be shortened by using the low-centric lens system, which is advantageous in mass production. The fiber laser welding may be a thermal conductivity type laser welding, but is preferably a deep penetration type welding (keyhole welding).

As the bonding conditions, ordinary conditions are selected according to the bonding method, the material used, the type of laser to be irradiated, and the like.
For example, in the fiber laser welding method, as a fiber laser welding device, a fiber laser welding device "ASF1J23" (trade name, manufactured by Furukawa Denki Kogyo Co., Ltd.) with an oscillation wavelength of 1084 nm (single mode oscillation laser light), 500 W, CW fiber laser Etc. can be used. Welding conditions are appropriately set according to the types of members for electrical and electronic equipment, and examples thereof include a laser beam output of 300 to 500 W and a laser light sweep speed of 50 to 250 mm / sec. , The laser light spot diameter at the focal position is adjusted to 20 μm, and laser light irradiation is performed with just focus. For example, when an insulated wire material is used as a member for electrical / electronic equipment, the welding conditions are appropriately changed depending on the number of conductors, the material, and the like. The sweep speed of the laser beam is 100 to 200 mm / sec. When the laser beam output is set to 300 to 500 W. Is set to. The irradiation time is set to a weldable time and is not uniquely determined by other irradiation conditions, but can be, for example, 0.01 to 10 seconds.
The light irradiation method of the fiber laser is not particularly limited as long as the conductor end and the connecting member can be welded. The fiber laser is usually irradiated from a connecting member mounted on the conductor end toward the conductor end, and the connecting member and the conductor end are melt-mixed and penetrate-welded. The irradiation direction of the fiber laser is not particularly limited, but the irradiation is performed from the axis of the conductor end or the axis direction of the connecting member toward the connecting member. The irradiation of the fiber laser may be spot irradiation, or the fiber laser may be continuously or intermittently swept (scanned) along the direction perpendicular to the axis to irradiate linearly or planarly.
By this welding, the connecting member and the vicinity of the end face of the conductor end are melted, solidified, and integrated from the laser beam irradiation surface (the surface of the connecting member) to the opposite back surface, thereby joining.
In the manufacturing method of the present invention, the joining is usually performed between the conductor end portion and the joining base portion of the connecting member, but a portion other than the conductor end portion and the joining base portion, for example, the hem portion can also be joined. However, it is preferable that the joint between the conductor end portion and the hem portion is performed as a temporary joint for reinforcing the positional deviation restraining function by the connecting member, and the joint between the conductor end portion and the joint base portion is the main joint.

By this joining step, the conductor end portion and the connecting member are joined, and accordingly, the conductor end portions arranged facing each other are also joined (via the connecting member).
In the electrical / electronic device connecting member joined in this way, the facing arrangement state of the conductor ends is restricted at the time of joining or during joining, and at least the conductor ends are narrowed with high strength and low resistance (for example). Welding allowance, welded part) are joined.
The electric / electronic device connecting member of the present invention exhibiting the above-mentioned excellent characteristics can be applied to electric / electronic devices, for example, electric wires for telephones, electric wires for transformers, and coils constituting motors of hybrid vehicles or electric vehicles. It is preferable to apply to. For example, it can be used as a winding forming a coil of a stator of a rotary electric machine (motor).
The coil using the electric / electronic device connecting member of the present invention can realize miniaturization and high performance of the electric / electronic device by being used in the electric / electronic device. Further, the coil using the electric / electronic device connecting member of the present invention in which an insulated electric wire material having a multi-core conductor is joined can realize an electric / electronic device having a small eddy current loss even in a high frequency region.

[Coil and electrical / electronic equipment]
The electric / electronic device connecting member of the present invention can be used as a coil in fields that require electrical characteristics (withstand voltage) and heat resistance, such as various electric / electronic devices. For example, the electric / electronic device connecting member of the present invention can be used for a motor, a transformer, or the like to form a high-performance electric / electronic device. In particular, it is suitably used as a winding for a drive motor of a hybrid car (HV) and an electric vehicle (EV). As described above, according to the present invention, the electric / electronic device connecting member of the present invention can be provided as a coil, and as an electric / electronic device using the coil, an HEV or an EV drive motor can be particularly provided.

The coil of the present invention has at least one electric / electronic device connecting member of the present invention, and preferably, as a member for the electric / electronic device, a plurality of wiring materials are joined by the connecting member. It has a connecting member.
The coil of the present invention may have a form suitable for various electric / electronic devices, and is formed by coiling the electric / electronic device connecting member of the present invention, or the electric / electronic device connecting member of the present invention. For example, a predetermined portion is electrically connected after being bent.
The coil formed by coiling the electric / electronic device connecting member of the present invention is not particularly limited, and examples thereof include a coil in which a long electric / electronic device connecting member (insulated electric wire material) is spirally wound. .. In such a coil, the number of windings of the insulated wire material is not particularly limited. Usually, an iron core or the like is used when winding an insulated electric wire material.

For example, the coil 40 shown in FIG. 9 is an example in which an insulated electric wire material having a multi-core conductor is used as the electrical / electronic device connecting member of the present invention. The coil 40 is formed by winding the insulated wire material 10F of the present invention one or more times in a groove 42 formed in the core 41. As shown in FIGS. 8 and 9, the insulated wire material 10F used for the coil 40 as an electrical / electronic device connecting member is made by laminating three divided conductors 11 having a conductor insulating layer 12 covering the outer periphery. Although it has a multi-core conductor 13 and an outer peripheral insulating layer 14 that covers the outer periphery of the multi-core conductor 13, the present invention is not limited to this, and an insulated electric wire material having a single-core conductor can also be used.

A coil used for a stator of a rotary electric machine or the like can be mentioned as a coil in which a predetermined portion is electrically connected after bending this insulated electric wire material. In such a coil, for example, as shown in FIGS. 10 and 11, a plurality of electric wire segments 54 are produced by bending a short insulated electric wire material into a U shape or the like. Then, a coil 53 (see FIG. 11) formed by alternately connecting (welding) two open end portions 54a such as a U-shape of each electric wire segment 54 can be mentioned.

The electric / electronic device using this coil is not particularly limited. As a preferable aspect of such an electric / electronic device, for example, a rotary electric machine (particularly an HV and EV drive motor) provided with the stator 50 shown in FIG. 11 can be mentioned. The rotary electric machine can have the same configuration as the conventional rotary electric machine except that the rotary electric machine is provided with the stator 50.
The stator 50 has the same configuration as the conventional stator except that the electric wire segment 54 (see FIG. 10) is formed of the member for electrical / electronic equipment of the present invention (preferably a short insulated electric wire material). Can be done. That is, in the stator 50, the stator core 51 and the electric wire segment 54 made of the members for electrical and electronic devices of the present invention are incorporated into the slot 52 of the stator core 51, for example, as shown in FIG. Then, the open end portion 54a is electrically connected to form the coil 53 (see FIG. 11). Here, in the stator 50, the electric wire segment 54 may be incorporated into the slot 52 as a single wire, but is preferably incorporated as a set of two wires as shown in FIG. In the stator 50, a coil 53 formed by alternately connecting open ends 54a, which are two ends of the electric wire segment 54 bent as described above, is housed in a slot 52 of the stator core 51. At this time, the open end portion 54a of the electric wire segment 54 may be connected and then stored in the slot 52, or the insulated segment 54 may be stored in the slot 52 and then the open end portion 54a of the electric wire segment 54 is bent. May be connected. The connection of the open end portion 54a is performed by the above-mentioned manufacturing method of the present invention, particularly fiber laser welding, in which a connecting member is attached to the open end portion 54a (conductor end portion) arranged facing each other and joined.

Since the open end portion 54a of the insulating electric wire material is electrically connected to the stator 50 by the manufacturing method of the present invention, the connecting portion can be narrowed. Moreover, even if the connection portion is narrowed, the connection strength is high and the increase in electrical resistance is suppressed. Therefore, the stator 50 can be miniaturized and have high performance.
Further, since the insulated wire material 10F uses a multi-core conductor, for example, the ratio of the cross-sectional area of the conductor to the slot cross-sectional area of the stator core (occupancy ratio) can be increased, and further high performance can be achieved. ..

Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited thereto.

[Example 1]
In this example, the electrical / electronic device connecting member 1 shown in FIGS. 1 and 2 was manufactured.
First, the insulated wire material 10A used for manufacturing the electrical / electronic device connecting member 1 was manufactured. Specifically, using oxygen-free copper having an oxygen content of 20 ppm or less, the four corners are chamfered with a radius of curvature r = 0.10 mm at 3.66 × 2.12 mm (width × thickness). A core conductor 16 was produced. A conductor insulating layer 12 (not shown in FIGS. 1 and 2) was formed of a thermoplastic resin, polyetherimide (PEI), on the outer periphery of the single-core conductor 16. When forming the conductor insulating layer 12, a die having a shape similar to that of the single-core conductor 16 was used to coat the outer periphery of the single-core conductor 16 with PEI varnish. The single-core conductor 16 coated with PEI varnish was passed through a baking oven having a furnace length of 8 m set at 450 ° C. at a speed of a baking time of 15 seconds. The PEI varnish was prepared by dissolving PEI (manufactured by Savik Innovative Plastics, trade name: Ultem 1010) in N-methyl-2-pyrrolidone (NMP). A polyetherimide layer having a thickness of 3 μm was formed in the baking step. In this way, a single-core conductor 16 (enamel wire) whose outer peripheral surface was covered with a conductor insulating layer 12 having a film thickness of 3 μm was obtained.

An outer peripheral insulating layer 14 of a thermoplastic resin was formed on the outer periphery of the single-core conductor 16 with the conductor insulating layer 12 thus produced by extrusion molding.
The screw of the extruder used was 30 mm full flight, L / D = 20, and a compression ratio of 3. The cylinder temperature in the extruder was set to the temperature of three zones, 300 ° C., 380 ° C., 380 ° C., the temperature of the head portion was set to 390 ° C., and the temperature of the die portion was set to 400 ° C. in order from the resin charging side. As the thermoplastic resin of the outer peripheral insulating layer 14, polyetheretherketone (PEEK: manufactured by Solvay Specialty Polymers, trade name: Ketaspire KT-820, relative permittivity 3.1, melting point 343 ° C.) was used.
After extrusion coating of polyetheretherketone was performed using an extrusion die, the mixture was allowed to stand for 10 seconds and then cooled with water. In this way, an outer peripheral insulating layer 14 having a thickness of 50 μm is formed on the outer periphery of the conductor insulating layer 12, and an insulated wire material having a cross-sectional size of 3.77 mm (width) × 2.23 mm (height) and a length of 30 cm. 10A was obtained.
Further, the outer peripheral insulating layer 14 and the conductor insulating layer 12 coated on the outer periphery of the single-core conductor 16 up to 10 mm from one end surface of the insulated wire material were removed.

On the other hand, an oxygen-free copper plate (thickness 1.0 mm) having an oxygen content of 20 ppm or less was press-processed to prepare the connecting member 20A shown in FIGS. 1 and 2. Both the connecting member 20A and the bottomed hole 21 have a rectangular parallelepiped shape.
The dimensions of this connecting member 20A are shown.
Vertical (horizontal dimension in FIG. 1): 5.8 mm
Width (corresponding to depth, horizontal dimension in FIG. 2): 6.5 mm
Height: 10 mm
Length of bottomed hole 21: 3.8 mm (thickness of peripheral wall portion 23a 1.0 mm)
Width of bottomed hole 21: 4.5 mm (thickness of peripheral wall portion 23a 1.0 mm)
Depth of bottomed hole 21: 5 mm (thickness of joint base 22a 5 mm)

Next, two insulating electric wire materials 10A were arranged in parallel, and the conductor ends of the insulated electric wire material 10A (the surface of the conductor from which both the insulating

layers

12 and 14 were peeled off) were arranged facing each other. At this time, the facing distance between the two conductor ends was 0.2 mm.
The conductor end portions arranged facing each other were inserted (press-fitted) until they hit the bottom surface of the bottomed hole 21 of the connection member 20A produced above, and the connection member 20A was attached to the conductor end portion. At this time, the width direction of the single-core conductor 16 is arranged along the vertical direction of the bottomed hole 21, and the thickness direction of the single-core conductor 16 is arranged along the lateral direction of the bottomed hole 21. did. At this time, the bottom surface of the bottomed hole 21 functions as a position shift restraining portion that restrains the position shift of the conductor end portion in the axial direction of the conductor end portion. Specifically, the bottom surface is in contact with the facingly arranged ends (end faces) of the single-core conductor 16, and the inner peripheral surface of the peripheral wall 23a of the bottomed hole 21 is the facing-facing end side surfaces of the single-core conductor 16. In contact with, the positional deviation of each of the single-core conductors 16 in the axial direction is restrained. Further, it functions as a positional deviation restraining portion that restrains the positional deviation of the conductor end portion in the direction in which the inner peripheral surface of the peripheral wall 23a intersects the axis of the conductor end portion. Specifically, the inner peripheral surface is in contact with the side surface of the end portion of the single-core conductor 16 arranged to face each other, and the positional deviation in the axial direction of each of the single-core conductor 16 is restrained. It restrains the positional deviation in the direction in which the facing distance between the ends of the single-core conductor 16 increases, and the positional deviation in the direction in which the overlap between the ends of the single-core conductor 16 changes. In this way, the positional deviation of the conductor end portion in the axial direction and the positional deviation in the direction intersecting the axial direction were restrained. The restrained state of the conductor end was confirmed by the fixed state of the insulated wire material 10A to which the connecting member 20A was attached.

Next, the conductor ends are welded to each other (via the connecting member 20A) by irradiating and welding the connecting member 20A from the outside in the axial direction toward the connecting member 20A by irradiating a fiber laser. An electric / electronic device connecting member 1 made of the insulated electric wire material 10A of the above was manufactured.
The fiber laser welding conditions are as follows.

<Fiber laser welding conditions>
Laser welding equipment: ASF1J23 (trade name, manufactured by Furukawa Electric Co., Ltd.), 500W, CW fiber laser laser beam output: 300W
Oscillation wavelength: 1084 nm (single mode oscillation laser light)
Sweep rate: 100 mm / sec.
Laser light spot diameter at focal position: 20 μm
All conditions Just focus laser light irradiation Laser light irradiation position: Axial direction of connecting member Laser light to irradiate from outside toward the connecting member (from top to bottom in FIGS. 1 and 2) Sweeping condition: Bottom Sweeping from the center of the surface of 22a to each end edge of the bottom 22a along the thickness direction of the single-core conductor (left-right direction in FIG. 2) in 1 second.

[Examples 2 to 4]
The electrical / electronic device connecting members 1 of Examples 2 to 4 were obtained in the same manner as in Example 1 except that the laser light output, the laser light sweeping speed, and the irradiation time were set to the values shown in Table 1.

[Examples 5 and 6]
Electrical / electronic device connecting members of Examples 5 and 6 in the same manner as in Examples 1 or 2 except that a tin layer plated to a thickness of 1 μm was used on the inner surface of the bottom portion 22a of the connecting member 20A. I got 1.

[Example 7]
The insulated wire material 10A and the connecting member 20A produced in Example 1 were joined with a conductive adhesive: TK paste CR-2800 (trade name, manufactured by Kaken Tech Co., Ltd.).
That is, a conductive adhesive was applied to the terminal portion, and then a connecting member was covered and cured at 120 ° C. for 30 minutes.

[Comparative Example 1]
After producing the insulated wire material 10A of 30 cm in the same manner as in Example 1, the outer peripheral insulating layer 14 and the conductor insulating layer 12 coated on the outer periphery of the single core conductor 16 up to 20 mm from one end surface of the insulated wire material 10A are removed. did. The conductor ends of the insulated wire material 10A were fixed to each other by a holding mechanism of a laser welding device in a state where they were arranged facing each other. The fixing location was set at a position 15 mm from the edge of the single-core conductor. With the face-to-face state fixed in this way, the electrical / electronic device connection member of Comparative Example 1 was manufactured by irradiating with a laser in the same manner as in Example 1 (same laser welding conditions).
[Comparative Example 2]
In the same manner as in Example 1, after producing the insulated wire material 10A of 30 cm, the outer peripheral insulating layer 14 and the conductor insulating layer 12 coated on the outer periphery of the single core conductor 16 from one end surface of the insulated wire material 10A to 10 mm are formed. Removed. The electricity and electronics of Comparative Example 2 are the same as in Example 1 except that the fiber laser is directly irradiated to the end of the conductor (without attaching the connecting member) with the insulated wire material 10A arranged face-to-face. Manufactured equipment connection members. However, in order to prevent the occurrence of blow holes and the like due to the presence of both insulating layers, the laser beam output was set to 30 W and the irradiation time was set to 10 seconds.

<Confirmation of welded part>
A cross section of the welded portion of each electrical / electronic device connecting member manufactured in each example (excluding Example 7) cut in a plane including the laser beam irradiation portion (central portion) was observed with an optical microscope. As a result, a welded portion (through welded portion) is formed from the connecting member to the ends of the two single-core conductors, and the two single-core conductors are welded through the bottom of the connecting member. I was able to confirm.

The following evaluations were performed on the electrical / electronic device connecting members of Examples 1 to 7 and Comparative Examples 1 and 2 manufactured in this manner. The evaluation results are shown in Table 1.

<Measurement of joint strength between conductor end and connecting member>
Regarding the electrical / electronic device connecting members manufactured in the same manner as in each of the examples and the comparative examples, two single-core conductors (insulated electric wire materials) and connecting members are used in accordance with JIS Z 2241: 2011. The tensile strength was measured by grasping each of them and performing a tensile test, and the average value thereof was calculated and used as the joint strength of the electrical / electronic device connecting member.
When the bonding strength was 300 MPa or more, it was determined to be "G" as if the two single-core conductors (insulated wire materials) and the connecting member were firmly bonded. On the other hand, if the welding was less than 300 MPa, it was judged as "N" as having insufficient joint strength. Pass was judged as "G". Table 1 shows the measured values and the judgment results.

<Blow hole presence confirmation test>
The cross-sectional area cut out in the above <confirmation of welded portion> (the portion where the copper of the single-core copper body and the connecting member is melted after welding (welded portion)) is observed with an optical microscope, and a blow hole having a diameter of 0.1 mm or more is observed. I counted the number.
When the number of blow holes is 10 or less, it is judged as "G" as having excellent weldability with a fiber laser (particularly, a characteristic of suppressing an increase in electrical resistance), and is judged to be acceptable. On the other hand, when the number of blow holes exceeds 10, it is judged as "N" because the weldability is inferior, and it is judged as rejected.

The following can be seen from Table 1.
That is, in Comparative Example 1 in which the conventional welding processing method is adopted, in order to hold the facing arrangement state of the conductor ends arranged facing each other by the holding mechanism, it is necessary to lengthen the conductor ends arranged facing each other. As a result, even if the welding strength and the blow hole generation test are passed (even if welding is possible with high strength and low resistance), the face-to-face arrangement length including the welding allowance cannot be narrowed or shortened. It is not possible to fully meet the demands for miniaturization and high performance of electronic devices.
On the other hand, Comparative Example 2 in which the end portions of the conductors arranged facing each other are shortened and welded without using a connecting member is dimensionally applicable to miniaturization, high performance, etc. of electrical / electronic equipment. The face-to-face arrangement state fluctuates during welding and during welding, and conductor ends cannot be welded to each other with high strength and low resistance, which is not sufficient as an electrical / electronic device connecting member in the first place.
On the other hand, in each of Examples 1 to 6, the positional deviation of the conductor end portion in the facing arrangement state can be effectively restrained by the connecting member, and the facing arrangement length of the conductor end portion (welding allowance). ) Can be shortened, but the conductor ends can be welded together with high strength and low resistance. Further, in Example 7, although the bonding is performed by using a conductive adhesive, since the positional deviation of the conductor end portions in the facing arrangement state can be effectively restrained, a sufficient bonding strength of 300 MPa can be achieved. In this way, if the facing-to-face arrangement length of the conductor ends can be shortened to shorten the welding allowance or the adhesive allowance (the length in which the insulating layer is peeled off in the embodiment) of the two insulated wire materials, the welding strength is stable. Therefore, improvement in reliability can be achieved. From the above results, the electrical / electronic device connecting member of the present invention is dimensionally and characteristically (strength and resistance, and appropriately reliable), such as miniaturization and high performance of the electrical / electronic device. Can fully meet the demands of. Therefore, when each of the electric / electronic device connecting members of Examples 1 to 7 is applied to a coil or an electric / electronic device, miniaturization and high performance can be realized.

Although the present invention has been described with its embodiments, we do not intend to limit our invention in any detail of the description unless otherwise specified, and contrary to the spirit and scope of the invention set forth in the appended claims. I think that it should be widely interpreted without.
