Description

The present invention relates to a terminal unit, a coil component including the same, and a method for manufacturing the coil component.

Patent Literature 1 discloses a reactor having a terminal block. In Patent Document 1, an input-side terminal block and an output-side terminal block are arranged at different levels with respect to the core direction according to the drawing positions of the input-side conductor wire and the output-side conductor wire in the core direction. .

JP 2016-143818 A

However, the reactor of Patent Document 1 has the following problems.

As a first aspect, in Patent Document 1, there is a step between female screw holes of two terminal connection portions (input-side terminal block and output-side terminal block, corresponding to the first connection portion of the present application) to which a connected component is connected. Therefore, workability such as screw tightening may be deteriorated when a screw is screwed into the female threaded hole.

In addition, since the lead wire of the coil is soldered to the fixed portion (corresponding to the second connection portion of the present application) on the same plane as the female screw hole of the terminal connection portion, the solder flows into the female screw hole etc. and hardens. There is a risk that the workability of screw tightening and the like may deteriorate.

As a second aspect, the coil specifications of the reactor are changed according to the required performance of the electrical equipment, and the relative positional relationship of each lead wire of the coil in the vertical direction can be assumed to vary accordingly. A coil component having a terminal unit with a high R is required.

For example, if the number of turns of the coil is designed to be relatively small, the distance between the lead wires in the vertical direction will be small. However, in the terminal block of Patent Literature 1, the height position of each terminal connection portion is fixed, so bending of the lead wire of the coil becomes large, and it may not be possible to reduce the size of the reactor. That is, the versatility was not satisfactory.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a terminal unit that can be miniaturized and has high connection workability and versatility.

According to one aspect of the present invention, there is provided a terminal unit for connecting a plurality of lead wires drawn out from a coil of a coil component to other connection wires, respectively, the terminal unit standing upright from the coil of the coil component. a terminal block having a plurality of insertion holes penetrating in the vertical direction along the winding core direction and arranged in the left-right direction and a support portion; a second connection portion formed to be bent from one of left and right ends of the connection portion and having a tip portion to which the lead wire is connected, the second connection portion being inserted into the insertion hole of the terminal block; In the used state, the first connecting portion includes a plurality of terminals supported by the supporting portion, and the first connecting portions of the plurality of terminals are aligned in vertical height positions, and the The vertical height positions of the second connection portions are different from each other.

According to this aspect, since the vertical height positions of the second connecting portions of the terminals are different from each other, it is possible to reduce the bending of the lead wire in the vertical direction, and it is possible to reduce the size of the coil component. . Furthermore, since the second connecting portion is formed so as to be bent from one of the left and right ends of the first connecting portion, the size of the coil component can be further reduced.

In addition, since the first connection part has the same top and bottom height positions, for example, when fixing other connection wires to the first connection part with screws, tightening work under common conditions etc., and connection workability is not impaired.

In addition, since the first connection portion and the second connection portion are separated from each other in the vertical direction, for example, even when a lead wire is soldered to the second connection portion, the solder affects the connection of the first connection portion. There is little fear of giving a , and the connection workability is not impaired.

According to the present invention, even when the vertical lead-out position of the lead-out wire of the coil of the coil component is changed, bending of the lead-out wire in the up-down direction can be reduced. Furthermore, since the first connecting portion has the same vertical height position, it is possible to perform tightening work under common conditions, and connection workability is not impaired.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The following description of preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its applicability or its uses.

A coil component according to the present embodiment is used, for example, in an electric device driven by an inverter circuit (not shown). In the present disclosure, a coil component is a general term for components having coils for adjusting voltage and current values, and is a concept including transformers such as transformers, reactors, choke coils, and the like. In the following embodiments, examples of reactors will be described.

-Composition of Reactor-
As shown in FIG. 1, the reactor A includes a reactor body 10 including a laminated core 1 and a coil 2 attached to the laminated core 1, and a terminal unit 3 for fixing lead wires 21a and 21b from the coil 2. Prepare. The reactor body 10 and the terminal unit 3 are fixed on a flat mounting base 4 . In the following description, the core direction of the coil 2 (thickness direction of the mounting base 4) is defined as the vertical direction, and the direction in which the reactor body 10 stands up with respect to the mounting base 4 is defined as the top.

The laminated core 1 is an EI-type core comprising an E-type laminated core 11 and an I-type laminated core 12 combined with the E-type laminated core 11 to form a closed magnetic circuit. The E-type laminated core 11 is formed by laminating E-type magnetic steel sheets and joining them together by welding them in the plate thickness direction (laminating direction) in an overlapping state. Similarly, the I-shaped laminated core 12 is formed by laminating I-shaped magnetic steel sheets and welding them together in the sheet thickness direction (laminating direction) in a layered state. Furthermore, the contact portions on the right and left sides of the E-type laminated core 11 and the I-type laminated core 12 are joined by welding. In FIG. 1 , the welded portions are denoted by 15 and 16 .

In the following description, the lamination direction of the laminated core 1 is defined as the front-rear direction, and the lead-out direction of the lead wires 21 (21a, 21b) of the coil 2 is defined as the front. Also, the longitudinal direction of the I-shaped laminated core 12 is defined as the left-right direction, and left-right is defined based on a front view (seen from the front side).

The coil 2 is composed of a rectangular electric wire 20 in which a wire made of copper or aluminum is covered with an insulator such as enamel. The flat electric wire 20 is wound so that the wide surface faces the inside of the coil 2 and has a substantially rectangular shape in a plan view (see FIG. 2B). A tape 23 is wound around the outer side of the coil 2 along the circumferential direction at a position overlapping the laminated core in plan view and at an intermediate position in the left-right direction on the front side. The electric wire used for the coil 2 is not limited to the rectangular electric wire 20, and may be an electric wire of other shapes such as an electric wire with a round cross section, or a bundled electric wire such as a litz wire. good too.

The lead wires 21 of the coil 2 are led out from the left and right sides of the coil 2, respectively. The leading wire 21 is stripped of the coating at the tip portion. In the following description, the lead wire drawn out from the right side of the coil may be described as a right lead wire 21a, and the lead wire drawn out from the left side of the coil as a left lead wire 21b.

The right lead wire 21a passes from left to right through a tape 23 wound on the front side of the coil 2 (hereinafter referred to as a front tape 23a) at a position near the lower end of the coil 2, and then extends to the right side of the front tape 23a. , and extends toward the right terminal 61, which will be described later. The left lead-out line 21b is passed through the front tape 23a from right to left at a position near the upper end of the coil 2, then bent forward from the left side of the front tape 23a, and extends toward a left terminal 62, which will be described later. extended. In FIG. 2A, the position where the coil is pulled out is hatched.

In this way, after the left and right lead wires 21 are passed through the front tape 23a, they are led out to the front side.

As shown in FIG. 3 , the terminal unit 3 includes a terminal block 30 and multiple conductive terminals 60 .

The terminal block 30 is integrally formed with a terminal block main body 31 including a bottom plate 31a and a back plate 31b which are integrally formed in a substantially L-shape when viewed from the side, and which protrudes forward from the upper end of the terminal block main body 31. and a terminal mounting portion 32 .

A back plate 31b of the terminal block main body 31 is formed with a screw hole 31e (see FIG. 3) penetrating in the front-rear direction at a position near the lower end in the center in the left-right direction. The screw hole 31e has an oval shape elongated in the vertical direction when viewed from the front.

Further, the terminal block main body 31 is provided with a plurality of ribs for the purpose of improving the strength of the terminal block 30 itself and increasing the strength against external forces in the front-back direction and the left-right direction. The ribs include a first rib 31c integrally protruding forward from the back plate so as to surround the upper side and the left and right sides of the screw hole in a rectangular shape when viewed from the front, and a first rib 31c extending upward from the upper plate of the first rib 31c. and a second rib 31 d extending to the terminal mounting portion 32 . Like the first rib 31c, the second rib 31d integrally protrudes forward from the back plate 31b.

The mounting base 4 has a mounting portion 41 that stands upright in front of the coil 2 . The mounting base 4 is, for example, a galvanized steel plate, and the mounting portion 41 is formed by notching a portion near the front end of the central portion in the left-right direction toward the rear in a U-shape and folding the inner portion forward. formed by causing Reference numeral 44 is attached to the U-shaped notch.

A threaded hole 42 (burring hole) is formed at a position corresponding to the threaded hole 31 e of the terminal block main body 31 in the central portion in the vertical and horizontal directions of the mounting portion 41 after being erected. Screw insertion portions 49 for screwing the reactor A to other equipment (not shown) are formed through the four corners of the mounting base 4 in the front, rear, left, and right directions.

The terminal block main body 31 is attached to the mounting base 4 via the screw holes 31e and 42 in a state in which the bottom surface of the bottom plate 31a is applied to the top surface of the mounting base 4 and the rear surface of the back plate 31b is applied to the front surface of the mounting portion 41. It is screwed and fixed to the portion 41 with a tap screw 48 (for example, a taptight screw). Hereinafter, the contact surface of the mounting base 4 with the terminal block main body 31 will be referred to as a mounting surface 43, the front surface of the mounting portion 41 with which the rear surface of the back plate 31b abuts 43a, and the bottom surface of the bottom plate 31a abuts. A reference numeral 43b is attached to the upper surface of the mounting base 4 that contacts.

The configuration of the present disclosure facilitates the work of attaching the terminal block 30 to the mounting base 4 after impregnation with varnish. Specifically, in the manufacturing process of the reactor A, after the reactor main body 10 is attached to the mounting base 4, the entire reactor A is impregnated with varnish in the attached state, and then turned upside down to drop the varnish and then dried. After that, the terminal block 30 is attached to the mounting base 4 .

In this embodiment, since the mounting surface 43 of the terminal block 30 is two surfaces, the front surface 43a of the mounting portion 41 and the upper surface 43b of the mounting base 4, the varnish easily drips when the reactor A is turned upside down. , the varnish is less likely to remain on the mounting surface 43 (the front surface 43a of the mounting portion 41 and the upper surface 43b of the mounting base 4). Moreover, since the terminal block 30 is attached to the mounting portion 41 with the tap screw 48, even if the varnish remains inside the screw hole 42 of the mounting portion 41, it does not affect screwing.

The terminal mounting portion 32 has a substantially rectangular parallelepiped mounting portion main body 33 integrally formed so as to protrude forward from the upper end of the terminal block main body 31 . A pair of terminal insertion holes 32a having a rectangular shape in plan view and penetrating in the vertical direction are formed side by side in the horizontal direction in the mounting portion main body 33 . A rear plate 32b is provided at the rear end of the mounting portion main body 33 so as to be flush with the rear surface of the mounting portion main body 33 . The rear surface of the back plate 32b is also flush with the rear surface of the back plate 31b of the terminal block main body 31. As shown in FIG. A partition plate 32c is provided upright between a right terminal 61 and a left terminal 62, which will be described later, between the terminal insertion holes 32a on the mounting portion main body 33. As shown in FIG.

In this way, by providing the back plate 32b and the partition plate 32c on the mounting portion main body 33, when connecting another connection electric wire (not shown) to the first connection portion 60a described later, the terminal is abutted. can be positioned by Thereby, workability can be improved.

One or both of the back plate 32b and the partition plate 32c may be omitted. Moreover, the terminal insertion hole 32a need only be formed so that the second connecting portion of the terminal 60, which will be described later, can be inserted therethrough, and does not need to be rectangular. For example, the terminal insertion hole 32a may be formed so as to have four rounded corners in plan view.

Each of the plurality of terminals 60 is bent into a substantially U-shape, and is provided with a flat plate-like first connection portion 60a located at the upper end in the used state of being inserted into the terminal insertion hole 32a. The first connection portion 60a has a screw hole 60b formed in the center in the front-rear and left-right direction for screwing and fixing a terminal (not shown) of another connection wire. The first connection portion 60a has a flange portion 60f wider than the hole diameter of the terminal insertion hole 32a in the front-rear direction. When the terminal 60 is inserted into the terminal insertion hole 32a, the flange portion 60f is caught by the front and rear walls of the terminal insertion hole 32a, so that the height positions of the first connection portions 60a of both terminals are aligned. there is A portion of the terminal mounting portion 32 where the flange portion 60f is caught is called a support portion 32d.

The support portion 32d is preferably configured to support the first connection portion 60a at a position higher than half the height of the coil, more preferably higher than the upper end of the coil 2, as shown in FIG. 2C. is configured to support the first connecting portion 60a at a higher position.

As a result, there is an advantage that when selecting a combination of terminals corresponding to the vertical height position of the lead wire of the coil, the options are expanded. That is, the vertical length of the terminal 60 (outer plate 60d) can be optimized. Furthermore, by configuring as shown in FIG. 2C, the length of the terminal 60 can be optimized regardless of the lead-out position of the lead-out wire 21 . For example, the length of the terminal 60 can be adjusted so that the lead wire 21 and a second connection end portion 60h described below can be connected at the shortest distance regardless of the vertical position of the coil 2. can.

Four corners of the first connecting portion 60a are bent upward to increase the strength of the terminal. A reference numeral 60g is attached to this folded portion.

Further, each of the plurality of terminals 60 has a pair of side plates extending downward from both left and right ends of the first connecting portion 60a, in other words, formed to be bent downward from both left and right ends. have. Here, of the pair of side plates, the side plate located on the inner side in the left-right direction is called the inner side plate 60c, and the side plate located on the outer side is called the outer side plate 60d. A second connection end portion 60h for connecting the lead wire 21 of the coil 2 is provided at each lower end portion (tip portion) of the outer plate 60d. The second connection end portion 60h is formed by bifurcating the lower end portion of the outer plate 60d and folding the outer plate 60d outward. With such a configuration, the state of soldering to the second connection end portion 60h can be visually observed, and the connectivity of the solder can be improved. Here, the outer plate 60d corresponds to the second connecting portion.

The plurality of terminals 60 include a plurality of types of terminals in which the first connection portion 60a and the inner plate 60c have the same shape, but the outer plate 60d has different lengths.

As a result, for example, by selecting terminals having different lengths of the outer plate 60d, it is possible to obtain a feature that the height positions of the second connection end portions 60h are different from each other when a plurality of terminals 60 are attached to the terminal attachment portion 32. have. That is, when the inner plate 60c and the outer plate 60d of each terminal 60 are inserted into the terminal insertion hole 32a from above, and the first connection portions 60a of both terminals 60 are supported by the support portion 32d so that the height positions are aligned. It is characterized in that the height positions of the second connection end portions 60h are different from each other.

A specific description will be given below together with the description of the method for manufacturing the reactor.

In the first step, the terminal block 30 configured as described above is prepared.

In the second step, a plurality of types of terminals 60 are prepared in which the first connecting portion 60a and the inner plate 60c have the same shape, but the outer plate 60d has different lengths. FIG. 3 shows an example in which three types of terminals 60 are prepared.

In the third step, a combination of terminals 60 corresponding to the vertical height position (also referred to as the drawing position) of the lead wires 21 a and 21 b of the coil 2 is selected from a plurality of types of terminals 60 . For example, in the example of FIG. 1, as described above, the right lead wire 21a is drawn from a position near the bottom of the coil 2, and the left lead wire 21b is drawn from a position near the bottom of the coil 2. Here, the “terminal corresponding to the position of the coil lead wire” includes the terminal 60 having a length such that the connection part is aligned with the vertical height position of the coil lead wire in the operating state, and the reactor Within the scope of achieving the purpose of the present application of miniaturizing the terminal 60, the concept includes the case where the vertical height position of the coil lead wire of the terminal 60 and the vertical length of the terminal are displaced from each other. be.

Therefore, as shown in FIG. 3, by selecting the long terminal of the outer plate 60d as the right terminal 60 (hereinafter referred to as the right terminal 61), the second connection end portion 60h of the right terminal 61 can be The vertical height position can be set low according to the position of the right lead line 21a. For ease of understanding, the outer plate of the right terminal 61 is denoted by 61d, and the second connecting end thereof by 61h in the drawings.

On the other hand, by selecting a short terminal of the outer plate 60d as the left terminal 60 (hereinafter referred to as the left terminal 62), the vertical height position of the second connection end portion 60h of the left terminal 62 can be adjusted in the state of use. , can be set high according to the position of the left lead line 21b. For the sake of clarity, in the drawings, etc., the outer plate of the left terminal 62 is denoted by 62d, and the second connection end is denoted by 62h.

In the fourth step, the plurality of terminals 60 (61, 62) forming the combination selected in the third step are inserted into the plurality of terminal insertion holes 32a.

As described above, according to the present embodiment, terminals having the same or different lengths in the vertical direction can be combined according to the lead-out position of the lead-out wire 21, and the versatility is improved while miniaturizing the reactor A. be able to. For example, it is possible to arbitrarily select a combination of a terminal having a short vertical length (the length of the outer plate 60d) and a long terminal, a combination of short terminals, and a combination of long terminals. While miniaturization is achieved, versatility for individual design of various coils can be enhanced.

For example, as shown in FIG. 6A, the right lead wire 21a is drawn from the upper position of the coil 2, the left lead wire 21b is drawn from the lower position of the coil 2, and the right lead wire 21a and the left lead wire are connected to each other. Even when the vertical distance from the line 21b is narrow, it is preferable to select a terminal from a plurality of types of terminals 60 according to the lead-out positions of the lead-out lines 21a and 21b. FIG. 6B illustrates a combination of terminals 60 (61, 62) with short vertical lengths, and FIG. 6C illustrates a combination of terminals 60 (61, 62) with long vertical lengths. is exemplified.

Furthermore, according to the present embodiment, the second connection end portion 61h of the right terminal 61 and the second connection end portion 62h of the left terminal 62 have different vertical height positions when in use. The vertical bending of the reactor can be reduced, and the size of the reactor can be reduced. For example, even if the right lead wire 21a and the left lead wire 21b have different lead positions (height positions in the vertical direction), the lead wires 21a and 21b do not have to be bent in the up-down direction, and the corresponding second lead wires 21a and 21b are not bent in the up-down direction. It can be connected to the connecting portions 61h and 62h.

Further, in the terminal unit of the present disclosure, the outer plate 60d of the terminal 60 serving as the second connecting portion is bent downward from one of the left and right outer ends of the first connecting portion 60a. Therefore, the size of the reactor can be further reduced. For example, if the first connection portion 60a is bent from the front-back direction end portion, the lead wire 21 needs to be wrapped around for connection.

In addition, in the terminal unit of the present disclosure, the height positions in the vertical direction of the first connection portions 60a of the plurality of terminals 60 in the used state are aligned with each other, that is, two screw holes or the like are arranged side by side. Since the heights are the same, it is possible to perform tightening work under common conditions, and connection workability is not impaired.

In addition, in the terminal unit of the present disclosure, soldering is performed at the second connection end portion 60h located below the first connection portion 60a, so there is little possibility that solder will enter the screw hole 60b of the first connection portion 60a. Connection workability is not impaired.

Further, in the terminal unit of the present disclosure, the terminal 60 is provided with an inner plate 60c facing the outer plate 60d, and the inner plate 60c is inserted through the terminal insertion hole 32a in addition to the outer plate 60d. As a result, the outer surfaces of both side plates 60c and 60d of the terminal 60 face the inner wall surface of the terminal insertion hole 32a and are inserted along the inner wall surface. As a result, the terminal can be prevented from wobbling in the left-right direction, and the strength of the terminal 60 can be ensured. Specifically, sufficient strength should be ensured even if external force is applied to the connection part between the terminal unit and other connection wires when the worker works or after the work of installing the coil part. be able to. In this embodiment, the first connecting portion 60a and the portions of the outer plate 60d and the inner plate 60c that are inserted into the terminal insertion holes 32a correspond to the holding portion.

Further, as shown in FIG. 4, at the lower end portion of the holding portion, that is, the lower end portion of the inner plate 60c and the intermediate position in the vertical direction of the outer plate 60d (position corresponding to the lower end of the mounting portion main body 33), A retaining portion 60e is provided for retaining the terminal 60 inserted through the terminal insertion hole 32a. The retaining portion 60e is bent in the left-right direction before the terminal 60 is inserted into the terminal insertion hole 32a. After the terminal 60 is inserted into the terminal insertion hole 32a, the retaining portion 60e is folded to prevent the retaining portion 60e from detaching.

In the above embodiment, the outer plate 60d of the terminal 60 is bent downward from the outer end of the first connecting portion 60a, but the present invention is not limited to this. Although not specifically illustrated, for example, the outer plate 60d of the terminal 60 may be bent upward from the outer end portion of the first connection portion 60a. Then, for example, the mounting portion main body 33 is provided below the lower end of the coil 2, and the plurality of terminals 60 (61, 62) are respectively inserted into the plurality of terminal insertion holes 32a from below, thereby The terminal 60 (61, 62) may be supported by a support portion 32d provided on the lower end side of the main body 33. FIG. Thereby, the same effects as those of the above-described embodiment can be obtained.

Further, in the above-described embodiment, a reactor is exemplified as a coil component. and a second terminal unit corresponding to the lead wire. The terminal units described in the above embodiments can be applied to each of the first terminal unit and the second terminal unit, and similar effects can be obtained.
