Description

TECHNICAL FIELD The present invention relates to a flexible terminal, a manufacturing method thereof, and an electrical component.

A flexible terminal having a flexible member configured by a bundle of a plurality of conductive wires, for example, is used as a member for connecting electrical equipment and the like to transmit power. A flexible terminal connects two objects to be connected, such as electrical equipment, via connection members made of a conductive material provided at both ends of the flexible member. Even if the flexible member that constitutes the flexible terminal can effectively absorb vibrations, or if the mode of use is such that the difference in thermal expansion is large and the amount of deformation is large, the flexible member does not experience thermal expansion and thermal contraction. It is a member that can effectively absorb dimensional fluctuations caused by

For example, as shown in FIG. 6, such a flexible terminal is formed by inserting the end portion of a flexible member 91 into the inner space of connecting members 92 and 93 having cylindrical inner spaces, and then By crushing 92 and 93, connecting members 92 and 93 are integrated with both end portions of flexible member 91, respectively. For example, Patent Literature 1 describes a structure having a notch that allows communication between the inside and outside of the connecting member in order to make it easier to confirm that the flexible member is inserted over the entire length of the internal space of the connecting member. there is Further, Patent Document 2 describes a flexible terminal having a configuration in which a portion of the connecting member is bent and bitten into the flexible member as a flexible terminal in which the connecting member is difficult to separate from the flexible member. . Further, in Patent Document 3, a SUS material pipe can be compressed into a flat shape in a state in which a flexible member made of a Ni wire braided wire or bundled stranded wire is arranged in the SUS material pipe.

Since each of the flexible terminals described in Patent Documents 1 to 3 has a flexible member configured by a bundle of a plurality of conductor wires, the two connection objects connected via the flexible terminal are: Even if an external force such as tension, compression, torsion, or the like acts and deformation occurs such that the positional relationship between the two objects to be connected is shifted, the flexible member bends to effectively absorb such deformation. Since the electrical or thermal connection between these connection objects can be continuously maintained, there is a high degree of freedom regarding the positional relationship between the two connection objects connected via the flexible terminal. However, in both ends of the flexible terminal described in Patent Documents 1 to 3, since the flexible member exists over the entire length of the crushed connecting member, the thickness of the both ends of the flexible terminal is the same as that of the flexible member. In addition, when electrically or thermally connecting two objects to be connected via a flexible terminal, the thickness of the connection member of the flexible terminal is increased. After inserting a bolt or the like in a state in which the through-hole of the object to be connected is aligned with the through-hole of the connecting object superimposed on the connecting member, a nut is screwed onto the bolt from the opposite side of the bolt insertion side and tightened. However, when the space for such work (especially the space in the thickness direction of the flexible terminal 1a) is narrow, there are cases where the work for connecting the flexible terminal cannot be performed.

Hereinafter, each embodiment of the flexible terminal of the present invention will be described in detail.

<First Embodiment of Flexible Terminal>
FIG. 1 is a perspective view showing an example of the configuration of a flexible terminal 1a according to this embodiment. A flexible terminal 1a according to this embodiment includes a flexible member 11 and a pair of connection members 12a and 13a. It has connection portions 121 and 131 that are integrally connected, and plate-like extension portions 122a and 132a that are smaller in thickness than the connection portions 121 and 131, respectively.

(flexible member)
The flexible member 11 is a member composed of a bundle of a plurality of conductor wires, and is capable of absorbing at least torsional deformation and compressive deformation. By using such a flexible member 11 for connecting two objects to be connected (not shown), forces such as tension, compression, and torsion act between the two objects to connect the two objects. Even if the objects are deformed such that the positional relationship between the objects is shifted, the flexible member 11 of the flexible terminal 1a is flexed to effectively absorb such deformation, and the electrical or thermal energy between the objects to be connected is maintained. can maintain continuous connection. In addition, it can absorb dimensional fluctuations due to vibration, thermal expansion, and thermal contraction even when used in environments with particularly strong vibrations or when used to connect objects with large differences in thermal expansion. .

Here, the cross-sectional shape of the flexible member 11 is preferably rectangular. This makes it easier for the flexible member 11 to bend, so that torsional deformation and compressive deformation can be easily absorbed. In addition, since heat dissipation from the flexible member 11 is promoted, adverse effects of heat on the electrical equipment can be reduced particularly when the object to be connected is the electrical equipment. On the other hand, in the case where the flexible member 11 is used for a heat transfer component and heat dissipation in the flexible member 11 is not desired, the cross-sectional shape of the flexible member 11 may be made substantially circular from the viewpoint of preventing heat loss. good.

Moreover, it is more preferable that the cross-section of the conductive wire constituting the flexible member 11 is substantially circular. As a result, the flexible member 11 can be easily bent in all directions, so that the degree of freedom regarding the positional relationship between the terminals can be further increased, and the flexible member 11 can easily absorb torsional deformation and compression deformation. be able to.

Moreover, it is preferable that the bundle of conductive wires constituting the flexible member 11 constitutes a braided wire or a stranded wire. As a result, the flexible member 11 can be easily deformed three-dimensionally in the length direction, width direction and thickness direction, and the flexibility is further enhanced to make it easier to absorb the deformation, thereby reducing disconnection of the conductor wire. can do.

The material of the conductive wire forming the flexible member 11 is determined according to the magnitude of electrical conductivity and thermal conductivity required in the flexible member 11 and flexibility. Among them, the conductive wire is preferably made of copper, stainless steel (SUS), aluminum, or nickel from the viewpoint of obtaining particularly high electrical conductivity and thermal conductivity as well as high flexibility. From the viewpoint of corrosion resistance, the surface of the conducting wire is preferably plated with, for example, tin, silver, or nickel. It should be noted that the surface of the conducting wire does not have to be plated.

(Connecting member)
The connection members 12a and 13a are members each made of a conductor material and having cylindrical internal spaces _S1 and _S2 . These connecting members 12a, 13a are crushed with both ends of the flexible member 11 inserted into a part of the respective internal spaces _S1 , _S2 , thereby separating the flexible member 11 and the connecting member. 12a and 13a are integrally connected. By providing such connection members 12a and 13a, the deformation can be absorbed by the entire flexible member 11 when the flexible terminal 1a is torsionally deformed or compressively deformed.

At least one of the pair of connecting members 12a and 13a includes connecting portions 121 and 131 integrally connected to the end portion of the flexible member 11 and extending from the connecting portions 121 and 131 to the side opposite to the flexible member 11.

The connecting portions 121 , 131 preferably have locking portions 123 , 124 , 133 , 134 crimped and fixed to the ends of the flexible member 11 . As a result, the flexible member 11 is locked to the connection members 12a and 13a, so that even if a tensile force is applied to the flexible terminal 1a, it is difficult to separate the connection members 12a and 13a from the flexible member 11. can be done.

The extension portions 122a and 132a are portions of the connection members 12a and 13a in which the internal spaces _S1 and _S2 are crushed without the flexible member 11 inside.

The extension portion 132a has a plate shape with a thickness t ₂ ' smaller than the thickness t ₁ ' of the connecting portion 131 . By having the extension portions 122a and 132a having a thickness smaller than that of the connection portions 121 and 131, the volume occupied by the terminal mounting portion is reduced. When the objects to be connected are connected to each other by using the flexible terminal 1a, the working space for connecting (attaching) the flexible terminal 1a to the object to be connected (especially the working space in the thickness direction of the flexible terminal 1a) is limited. However, the flexible terminal 1a can be connected to the object to be connected.

Here, the thickness dimensions t ₁ and t ₁ ′ of the connecting portions 121 and 131 can be the average thicknesses of the connecting portions 121 and 131 at the portion where the flexible member 11 is inserted. Further, the thickness dimensions t ₂ and t ₂ ′ of the extension portions 122a and 132a are the minimum thicknesses of the portions where the internal spaces S ₁ and S ₂ are crushed without the flexible member 11 inside. can be a value.

The materials of the connection members 12a and 13a are determined according to the electrical conductivity and thermal conductivity required in the connection members 12a and 13a and the mechanical strength. Among them, the connection members 12a and 13a are preferably made of copper, stainless steel (SUS), aluminum, or nickel from the viewpoint of obtaining particularly high electrical conductivity and thermal conductivity as well as high mechanical strength. Here, the surfaces of the connection members 12a and 13a may be plated with tin, silver, or nickel, for example. The surfaces of the connection members 12a and 13a may not be plated.

Also, the thickness t ₃ ′ of the conductor plate 15c is smaller than the thickness t ₁ ′ of the connecting portion 131, like the extended portion 132c. As a result, the flexible terminal 1c can be connected to the object to be connected even when there is a restriction on the working space for connecting the flexible terminal 1c to the object to be connected. In addition, since the thicknesses t ₃ and t ₃ ′ can be determined independently of the thicknesses of the connection members 12c and 13c, desired mechanical properties can be obtained at the connection portion of the flexible terminal 1c to the object to be connected. can have. The thickness dimension t ₃ , t ₃ ′ of the conductor plates 14c, 15c may be the same as the thickness dimension of the extensions 122c, 132c, or may be the same as the thickness dimension of the extensions 122c, 132c. can be different.

The connection between the conductor plate 14c and the extension portion 122c and the connection between the conductor plate 15c and the extension portion 132c can be performed by welding, friction stir welding, or the like. Welded portions 161 and 162 are formed at these connecting portions. In the flexible terminal 1c according to the present embodiment, the extension portions 122c and 132c formed by crushing are plate-like, so that the conductor plates 14c and 15c can be easily welded to the ends of the extension portions 122c and 132c. .

The flexible terminal 1c can be more firmly fixed to the object to be connected. Here, a plurality of connecting holes 141 and 151 are provided in at least one of the conductor plates 14c and 15c in order to prevent the terminal of the object to be connected from rotating while in contact with the conductor plates 14c and 15c. is preferred.

The material of the conductor plates 14c and 15c is determined according to the electrical conductivity and thermal conductivity required in the conductor plates 14c and 15c and the mechanical strength. Among them, the conductive plates 14c and 15c are preferably made of copper, stainless steel (SUS), aluminum, or nickel from the viewpoint of obtaining particularly high electrical conductivity and thermal conductivity as well as high mechanical strength. Here, the surfaces of the conductor plates 14c and 15c may be plated with tin, silver, or nickel, for example. The surfaces of the conductor plates 14c and 15c may not be plated.

The conductor plates 14c and 15c may be configured to extend in the same direction as the extensions 122c and 132c as shown in FIG. 4, but the present invention is not limited to this.

More specifically, as shown in FIG. 5(a), a conductor plate 15d extending in a direction different from that of the extending portion 132d may be formed on substantially the same plane as the end portion of the extending portion 132d. . Further, as shown in FIG. 5(b), a connecting hole 151, which is a portion to be fixed to a connecting object, is formed on a plate surface extending stepwise from the end of the extending portion 132e. The conductor plate 15e may be bent so as to be substantially parallel to the installation portion 132e. Further, as shown in FIG. 5(c), the conductor plate is arranged such that the connecting hole 151, which is the portion to be fixed to the connection object, is provided on the width end surface side orthogonal to the plate surface of the extension portion 132f. 15f may be bent.
