Description

[Technical Field]

[0001] The present disclosure relates to an electric wire with a terminal and a method for manufacturing the same, a terminal for an electric wire, and an electric wire with a connector. [Background technology]

[0002] 2. Description of the Related Art Conventionally, various methods for electrically connecting a terminal and an electric wire have been studied.

[0003] For example, Patent Document 1 describes a mechanism for establishing an electrical connection between a tab contact (a flat terminal) and a high-current conductor (a connection partner of the flat terminal). The mechanism has a retention structure for mounting on a contact area of ​​the high-current conductor, and the retention structure has at least one pressing element (e.g., a spring-like element) configured to generate contact pressure in the direction of the connection area. The pressing element has an overall elongated shape.

[0004] A conventional technique for connecting the above-described terminal and electric wire is ultrasonic bonding, which uses ultrasonic vibrations to bond the terminal and electric wire. However, during ultrasonic bonding, stress caused by the ultrasonic vibrations tends to concentrate on components, such as the pressing element, which are small relative to the joint between the terminal and the electric wire. This can cause cracks in the pressing element, and in the worst case, can lead to breakage. [Prior art documents] [Patent documents]

[0010] Hereinafter, a detailed description will be given based on an embodiment.

[0011] As a result of extensive research, the present inventors have discovered that the occurrence of cracks and breakage in members constituting a terminal is correlated with the direction of ultrasonic vibration when ultrasonically joining a terminal and an electric wire and the extension direction of the members. Based on this finding, the present inventors have discovered that by setting the angle α between the extension direction of a pressing member, which is one of the members constituting the terminal, and the longitudinal direction of the conductor constituting the electric wire within a predetermined range, and / or by setting the angle β between the in-plane direction of a support surface that supports the pressing member and the longitudinal direction of the conductor within a predetermined range, it is possible to suppress the occurrence of cracks in the pressing member and the breakage of the pressing member even when ultrasonically joining a terminal and an electric wire, and have completed the present disclosure based on this finding.

[0012] An electric wire with a terminal according to an embodiment has a terminal including a main body and a connecting portion connected to the main body, and a conductor of the electric wire is joined to the connecting portion of the terminal. The main body has one or more pressing members supported on a support surface of the main body. The angle α between the extension direction of the pressing members and the longitudinal direction of the conductor is not 90 degrees, and / or the angle β between the in-plane direction of the support surface of the main body and the longitudinal direction of the conductor is not 180 degrees.

[0013] A method for manufacturing an electric wire with a terminal according to an embodiment is a method for manufacturing an electric wire with a terminal in which a conductor wire of an electric wire is joined to a connection portion of a terminal having a main body portion and a connection portion connected to the main body portion. The main body portion has one or more pressing members supported on a support surface of the main body. The method for manufacturing an electric wire with a terminal includes applying ultrasonic vibrations to the connection portion and the conductor wire while applying pressure to the connection portion of the terminal and the conductor wire of the electric wire so that the angle α between the extension direction of the pressing member and the longitudinal direction of the conductor wire is not 90 degrees and / or the angle β between the in-plane direction of the support surface of the main body portion and the longitudinal direction of the conductor wire is not 180 degrees, thereby joining the connection portion and the conductor wire.

[0014] The terminal for an electric wire according to the embodiment includes a main body and a connection part connected to the main body. The main body has one or more pressing members supported on a support surface of the main body. The angle α between the extension direction of the pressing members and the connection direction connecting the main body and the connection part is not 90 degrees, and / or the angle β between the in-plane direction of the support surface of the main body and the connection direction connecting the main body and the connection part is not 180 degrees.

[0015] (First embodiment) FIG. 1 is a perspective view showing an example of an electric wire with terminal according to the first embodiment. FIG. 2 is a perspective view showing an example of a terminal according to the first embodiment. FIG. 3 is a front view showing an example of the terminal according to the first embodiment as viewed from the longitudinal direction of the conductor. FIG. 4 is an enlarged perspective view showing an example of a pressing member constituting the terminal according to the first embodiment. FIG. 5 is an enlarged front view showing an example of a pressing member constituting the terminal according to the first embodiment. FIG. 6 is a perspective view showing an example of an electric wire with connector according to the first embodiment. As shown in FIGS. 1 to 6, the electric wire with terminal 1 includes a terminal 2 and an electric wire 3, and a conductor 32 of the electric wire 3 is joined to a connecting portion 22 of the terminal 2.

[0016] 1, the electric wire 3 includes a conductor 32 and an insulating coating 33 that covers the outer periphery of the conductor 32. A sheath (not shown) that covers the outer periphery of the insulating coating 33 is provided outside the insulating coating 33. At one end side of the electric wire 3 (the left end side in FIG. 1), the insulating coating 33 that covers the outer periphery of the conductor 32 and the sheath (not shown) that covers the outer periphery of the insulating coating 33 are stripped from the electric wire 3, exposing the conductor 32.

[0017] The conductor 32 of the electric wire 3 may be made up of a plurality of element wires 31 as shown in Fig. 1, or may be made up of a single element wire 31. When the conductor 32 is made up of a plurality of element wires 31, the conductor 32 may be a stranded wire in which the plurality of element wires 31 are twisted together, or may be a bundled wire in which the plurality of element wires 31 are bundled together.

[0018] The terminal 2 is a terminal for an electric wire and includes a main body 21 and a connecting portion 22. The connecting portion 22 is connected to the main body 21 in a direction along the longitudinal direction of the conductor 32. The connecting portion 22 is a joining member that joins to the conductor 32 of the electric wire 3.

[0019] A conductor 32 exposed at one end of the electric wire 3 is joined to the connection portion 22 of the terminal 2. In this way, the terminal 2 and the electric wire 3 are electrically connected.

[0020] The main body portion 21 and the connecting portion 22 may be indirectly connected via the connecting portion 23 as shown in the figure, or may be directly connected without the connecting portion 23 .

[0021] The main body 21 of the terminal 2 has one or more pressing members 24. The pressing members 24 are supported by a pair of opposing support surfaces 21a, 21b of the main body 21. The size of each pressing member 24 is smaller than that of the connecting portion 22. Examples of the pressing members 24 include spring members such as leaf springs.

[0022] The pressing member 24 may be provided directly on the main body 21, or may be provided indirectly on the main body 21 via a pair of inner plate members 25 provided on the surfaces of the support surfaces 21a, 21b as shown in the figure. When the pressing member 24 is provided on the main body 21 via the inner plate members 25, the support surfaces 21a, 21b are opposing surfaces of the pair of inner plate members 25 that face each other.

[0023] As will be described later, the pressing member 24 is a portion that comes into contact with a conductor member C (see FIG. 6) such as a bus bar inserted between a pair of support surfaces 21a, 21b of the terminal 2. Although a single pressing member 24 may be provided, it is preferable that the terminal 2 includes a plurality of pressing members 24 as shown in the figure in order to ensure stable electrical contact between the pressing member 24 and the conductor member C. Furthermore, the pressing member 24 may be provided on only one of the support surfaces 21a and 21b, but for the same reason, it is preferable that the pressing member 24 is provided on both the support surfaces 21a and 21b as shown in the figure.

[0024] The base end portion of the pressing member 24 is joined to the support surface 21a (support surface 21b) of the main body 21, and the pressing member 24 extends from one of the pair of support surfaces 21a, 21b, 21a (support surface 21b), toward the other support surface 21b (support surface 21a).

[0025] 4 and 5, the pressing member 24 has a contact portion 24a that comes into contact with the conductor member C. The contact portion 24a of the pressing member 24 is closer to the support surface 21b (support surface 21a) that faces the support surface 21a (support surface 21b) that is connected to the base end portion of the pressing member 24 than to the base end portion of the pressing member 24.

[0026] The pressing member 24 connected to the support surface 21a has an elastic force such that when a force in the direction of the support surface 21a is applied to the contact portion 24a, a force directed toward the opposing support surface 21b acts on the contact portion 24a. Moreover, the pressing member 24 connected to the support surface 21b has an elastic force such that when a force in the direction of the support surface 21b is applied to the contact portion 24a, a force directed toward the opposing support surface 21a acts on the contact portion 24a.

[0027] 5, in the electric wire with terminal 1, the angle α formed between the extending direction of the pressing member 24 and the longitudinal direction of the conductor 32 is not 90 degrees. The extending direction of the pressing member 24 is the direction connecting the base end portion of the pressing member 24 and the contact portion 24a. The longitudinal direction of the conductor 32 corresponds to the extending direction of the conductor 32 and the connecting direction connecting the main body 21 and the connecting portion 22 of the terminal 2.

[0028] When the angle α between the extension direction of the pressing member 24 and the longitudinal direction of the conductor 32, which corresponds to the direction of ultrasonic vibration during ultrasonic bonding, is not 90 degrees, i.e., not perpendicular, the vibration amplitude of the pressing member 24 caused by the ultrasonic vibration during ultrasonic bonding to bond the connection portion 22 of the terminal 2 and the conductor 32 of the electric wire 3 is reduced compared to when the angle is 90 degrees, and stress concentration on the pressing member 24, which has a minute shape, is alleviated. As a result, cracks in the pressing member 24 and breakage of the pressing member 24 can be suppressed.

[0029] Similarly, when the angle α between the extension direction of the pressing member 24 and the connecting direction connecting the main body 21 and the connecting portion 22, which corresponds to the direction of ultrasonic vibration during ultrasonic bonding, is not 90 degrees, i.e., not perpendicular, the vibration amplitude of the pressing member 24 caused by the ultrasonic vibration during ultrasonic bonding to bond the connecting portion 22 and the conductor 32 is reduced compared to when the angle α is 90 degrees, and stress concentration on the pressing member 24 is alleviated. This makes it possible to suppress cracks in the pressing member 24 and breakage of the pressing member 24.

[0030] From this viewpoint, the angle α is preferably 60 degrees or less, more preferably 45 degrees or less, and most preferably 0 degrees.

[0031] Furthermore, when the angle α is not 90 degrees, the dimensions of the main body 21 in the direction perpendicular to the longitudinal direction of the conductor 32 can be made more compact than when the angle α is 90 degrees.

[0032] Furthermore, in the manufacturing method of the electric wire with terminal 1, ultrasonic vibrations are applied to the connection portion 22 and the conductor 32 of the electric wire 3 while the connection portion 22 of the terminal 2 and the conductor 32 of the electric wire 3 are pressed together in a state in which the angle α between the extension direction of the pressing member 24 and the longitudinal direction of the conductor 32 is not 90 degrees, thereby joining the connection portion 22 and the conductor 32. Note that in the pressurized state, the angle α between the extension direction of the pressing member 24 and the connecting direction connecting the main body 21 and the connection portion 22 is also not 90 degrees.

[0033] As described above, in order to prevent the occurrence of cracks in the pressing member 24 or breakage of the pressing member 24 due to ultrasonic bonding, the angle α of the pressing state in the manufacturing method of the electric wire with terminal 1 is preferably 60 degrees or less, more preferably 45 degrees or less, and most preferably 0 degrees.

[0034] 6 and 7, the connector-attached electric wire 4 includes a connector housing 51 that accommodates the terminal-attached electric wire 1 and at least the terminal 2 of the terminal-attached electric wire 1. The connector housing 51 of the connector 5 is provided with an opening 51a through which the conductor member C, such as a bus bar, can be inserted from the outside to the inside of the connector housing 51 so that the conductor member C is electrically connected to the contact portion 24a of the pressing member 24. The connector housing 51 is also provided with an insertion portion 51b through which the electric wire 3 is inserted.

[0035] In Figure 6, the opening 51a opens in a direction perpendicular to the longitudinal direction of the conductor 32, but if the conductor member C is installed at an angle from the unit, as shown in Figure 7, if the opening 51a opens in a direction that is not perpendicular to the longitudinal direction of the conductor 32, for example, in the extension direction of the pressing member 24, the entire unit can be made compact and the conductor member C, which is installed at an angle, can be easily inserted into the opening 51a, which opens at an angle.

[0036] According to the first embodiment described above, by setting the angle α within a predetermined range, it is possible to suppress the occurrence of cracks in the pressing member and the breakage of the pressing member even when the terminal and the electric wire are ultrasonically joined.

[0037] Although the above example shows that all of the pressing members 24 extend in the same direction, all of the pressing members 24 may extend in different directions, or some of the pressing members 24 may extend in the same direction. Furthermore, the arrangement of the pressing members 24 supported by the support surface 21a and the pressing members 24 supported by the support surface 21b may be symmetrical as shown in the figure, or may be asymmetrical.

[0038] In addition, in the above, the opening through which the conductor member C is inserted is an opening 51a that opens in a direction perpendicular to the longitudinal direction of the conductor 32, but it may also be an opening 51c that opens in the longitudinal direction of the conductor 32.

[0039] (Second embodiment) Fig. 8 is a perspective view showing an example of an electric wire with a terminal according to the second embodiment, Fig. 9 is a perspective view showing an example of a terminal according to the second embodiment, and Fig. 10 is a perspective view showing an example of an electric wire with a connector according to the second embodiment.

[0040] In the following embodiments, the same components as those of the electric wire with terminal 1 of the first embodiment are denoted by the same reference numerals, and redundant explanations will be omitted or simplified.

[0041] The electric wire with terminal 1a of the second embodiment is basically the same in configuration as the electric wire with terminal 1 of the first embodiment, except that the angle β formed between the in-plane direction of the support surfaces 21a, 21b of the main body 21 and the longitudinal direction of the conductor 32 is different. Therefore, the different configuration will be mainly described here.

[0042] 8 to 10, the electric wire with terminal 1a includes a terminal 2a and an electric wire 3, and is formed by joining a conductor 32 of the electric wire 3 to a connecting portion 22 of the terminal 2a. The terminal 2a includes a main body 21 and a connecting portion 22. The electric wire with connector 4a includes the electric wire with terminal 1a and a connector housing 51 that accommodates at least the terminal 2a of the electric wire with terminal 1a.

[0043] The angle β formed between the in-plane direction of the support surfaces 21a and 21b of the main body 21 constituting the terminal 2a and the longitudinal direction of the conductor 32 is not 180 degrees. That is, the in-plane direction of the support surfaces 21a and 21b of the main body 21 constituting the terminal 2a is different from the longitudinal direction of the conductor 32. The in-plane direction of the support surfaces 21a and 21b is the direction away from the coupling portion 23, and the longitudinal direction of the conductor 32 is the direction from the connection portion 22 of the terminal 2a toward the electric wire 3. In this way, when the angle β formed between the in-plane direction of the support surfaces 21a and 21b and the longitudinal direction of the conductor 32, which corresponds to the direction of ultrasonic vibration during ultrasonic bonding, is not 180 degrees, compared to when the angle β is 180 degrees, the vibration amplitude of the pressing member 24 caused by ultrasonic vibration during ultrasonic bonding to bond the connection portion 22 of the terminal 2a and the conductor 32 of the electric wire 3 is reduced, and stress concentration on the pressing member 24, which has a fine shape, is alleviated. Therefore, the occurrence of cracks in the pressing member 24 and the breaking of the pressing member 24 can be suppressed.

[0044] Similarly, when the angle β formed between the in-plane direction of support surfaces 21a, 21b of main body 21 and the connecting direction connecting main body 21 and connecting portion 22 is not 180 degrees, i.e., when the in-plane direction of support surfaces 21a, 21b is different from the connecting direction, the vibration amplitude of pressing member 24 caused by ultrasonic vibrations during ultrasonic bonding to bond connecting portion 22 of terminal 2a and conductor 32 of electric wire 3 is reduced compared to when the angle is 180 degrees, and stress concentration on pressing member 24, which has a minute shape, is alleviated. Therefore, cracks in pressing member 24 and breakage of pressing member 24 can be suppressed.

[0045] From this viewpoint, the angle β is preferably 90 degrees or more and 150 degrees or less, more preferably 90 degrees or more and 135 degrees or less, and most preferably 90 degrees.

[0046] Furthermore, in the manufacturing method of the electric wire with terminal 1a, ultrasonic vibrations are applied to the connection portion 22 and the conductor 32 of the electric wire 3 while the connection portion 22 of the terminal 2a and the conductor 32 are pressurized in a state in which the angle β formed between the in-plane direction of the support surfaces 21a, 21b of the main body 21 and the longitudinal direction of the conductor 32 is not 180 degrees, thereby joining the connection portion 22 and the conductor 32. Note that in the pressurized state, the angle β formed between the in-plane direction of the support surfaces 21a, 21b and the connecting direction connecting the main body 21 and the connection portion 22 is also not 180 degrees.

[0047] As described above, from the viewpoint of suppressing the occurrence of cracks in the pressing member 24 or the breakage of the pressing member 24 due to ultrasonic bonding, the angle β of the pressing state in the manufacturing method of the terminal-attached electric wire 1a is preferably 90 degrees or more and 150 degrees or less, more preferably 90 degrees or more and 135 degrees or less, and most preferably 90 degrees.

[0048] Furthermore, when the angle α of the electric wire with terminal 1a is within the range of the first embodiment, the occurrence of cracks in the pressing member 24 and the breaking of the pressing member 24 can be further suppressed.

[0049] According to the second embodiment described above, by setting the angle β within a predetermined range, it is possible to suppress the occurrence of cracks in the pressing member and the breakage of the pressing member even when the terminal and the electric wire are ultrasonically joined.

[0050] (Third embodiment) Fig. 11 is a perspective view showing an example of an electric wire with a terminal according to a third embodiment, Fig. 12 is a perspective view showing an example of a terminal according to the third embodiment, and Fig. 13 is a perspective view showing an example of an electric wire with a connector according to the third embodiment.

[0051] The electric wire with terminal 1b of the third embodiment has basically the same configuration as the electric wire with terminal 1 of the first embodiment, except for the different connection angle γ between the main body portion 21 and the connection portion 22. Therefore, the different configuration will be mainly described here.

[0052] 11 to 13, the electric wire with terminal 1b includes a terminal 2b and an electric wire 3, and is formed by joining a conductor 32 of the electric wire 3 to a connecting portion 22 of the terminal 2b. The terminal 2b includes a main body 21 and a connecting portion 22. The electric wire with connector 4b includes the electric wire with terminal 1b and a connector housing 51 that accommodates at least the terminal 2b of the electric wire with terminal 1b.

[0053] In the electric wire with terminal 1b, similarly to the electric wire with terminal 1, the in-plane direction of the support surfaces 21a and 21b of the main body 21 and the longitudinal direction of the conductor 32 are parallel to each other.

[0054] The connection angle γ between the main body portion 21 and the connecting portion 22 is not 180 degrees. In the illustration, the connecting portion 22 is connected perpendicularly to the main body portion 21 so as to move away from (below) the pressing member 24. The longitudinal direction of the conductor 32 joined to the connecting portion 22 corresponds to the direction of ultrasonic vibration during ultrasonic bonding. Thus, when the connection angle γ between the main body portion 21 and the connecting portion 22 is not 180 degrees, the vibration amplitude of the pressing member 24 caused by ultrasonic vibration during ultrasonic bonding to join the connection portion 22 of the terminal 2b to the conductor 32 of the electric wire 3 is reduced compared to when the connection angle γ is 180 degrees, and stress concentration on the pressing member 24, which has a fine shape, is alleviated. This prevents cracks from occurring in the pressing member 24 and breakage of the pressing member 24.

[0055] From this viewpoint, the connection angle γ is preferably 90 degrees or more and 150 degrees or less, more preferably 90 degrees or more and 135 degrees or less, and most preferably 90 degrees.

[0056] In addition, the manufacturing method of the electric wire with terminal 1b is such that, in a state where the connection angle γ between the main body portion 21 and the connecting portion 22 is not 180 degrees, pressure is applied to the connection portion 22 of the terminal 2b and the conductor 32 of the electric wire 3, and ultrasonic vibrations are applied to the connection portion 22 and the conductor 32 to join the connection portion 22 and the conductor 32.

[0057] As described above, from the viewpoint of suppressing the occurrence of cracks in the pressing member 24 or the breakage of the pressing member 24 due to ultrasonic bonding, the connection angle γ in the pressurized state in the manufacturing method of the terminal-attached electric wire 1b is preferably 90 degrees or more and 150 degrees or less, more preferably 90 degrees or more and 135 degrees or less, and most preferably 90 degrees.

[0058] According to the third embodiment described above, by setting the connection angle γ within a predetermined range, it is possible to prevent cracks from occurring in the pressing member and breakage of the pressing member even when ultrasonically joining the terminal and the electric wire. Note that, although an example in which the connection portion 22 is joined downward relative to the main body portion 21 has been described in Figures 11 to 13, the connection portion 22 may also be joined upward relative to the main body portion 21 to the extent that there is no interference between the terminal body and the ultrasonic joining device.

[0059] Although the embodiments have been described above, the present invention is not limited to the above embodiments, but includes all aspects encompassed by the concept and scope of the claims of the present disclosure, and can be modified in various ways within the scope of the present disclosure.
