Description

TECHNICAL AREA

[0001] The present invention relates to an electrical conductor wire provided with a terminal contact, wherein a terminal contact and an electrical conductor wire are electrically connected, and to a method for manufacturing the electrical conductor wire provided with a terminal contact. STATE OF THE ART

[0002] The prior art has proposed producing an electrical conductor wire provided with a terminal contact by using a terminal contact comprising: a connecting section to be connected to a mating terminal contact; and a crimp section having a tubular shape that is continuous without a slot in a circumferential direction (so-called closed drum shape) and that is crimped onto a conductor core wire of an electrical conductor wire (see, for example, patent literature 1). BIBLIOGRAPHY PATENT LITERATURE

[0003] Patent Literature 1: JP2017-224396A SUMMARY OF THE INVENTIONAL PROBLEM

[0004] In the above type of electrical conductor wire with a terminal contact, the conductor core of the electrical conductor wire is generally inserted into the tube of the crimp section of the terminal contact. The crimp section is then crimped so that it is compressed towards the tube, using a crimping die to crimp the crimp section and the conductor core, thus electrically connecting the terminal contact and the electrical conductor wire. Due to this design, in this type of electrical conductor wire with a terminal contact, the thickness of the crimp section and the inner diameter of the crimp section tube are varied according to the thickness of the electrical conductor wire (in other words, the bundle diameter of the conductor core wire being inserted into the crimp section tube).This means that in the production of electrical conductors with terminal contacts, a special terminal contact is used that meets a required specification, such as the thickness of the electrical conductor. Therefore, the terminal contact cannot be shared, and it is difficult to reduce the production costs of electrical conductors with terminal contacts.

[0005] An objective of the present invention is to provide an electrical conductor wire provided with a terminal contact which is able to meet a variety of specifications while sharing a terminal contact, and a method for manufacturing the electrical conductor wire provided with a terminal contact. SOLUTION TO THE PROBLEM

[0006] To achieve the above-described goal, an electrical conductor wire provided with a terminal contact according to the present invention and a method for manufacturing the electrical conductor wire provided with a terminal contact are characterized as follows.

[0007] An electrical conductor fitted with a terminal includes a terminal contact, an electrical conductor connected to the terminal contact, and a tubular component that covers an electrical contact between the terminal contact and the electrical conductor. The terminal contact comprises a pin-shaped contact section, the electrical conductor comprises a conductor core wire electrically connected to the contact section, and the tubular component is arranged such that the conductor core wire is embedded between an outer circumferential surface of the contact section and an inner tubular surface of the tubular component. The tubular component presses the conductor core wire toward the outer circumferential surface of the contact section to crimp the contact section and the conductor core wire.

[0008] A method for manufacturing an electrical conductor wire provided with a terminal contact, wherein a terminal contact and an electrical conductor wire are electrically connected, the method comprising a step of arranging a conductor core wire of the electrical conductor wire to cover an outer circumferential surface of a pin-shaped contact section of the terminal contact; a step of preparing a tubular component having an inner tubular surface with an inner diameter enabling the conductor core wire to be enclosed between the inner tubular surface and the outer circumferential surface of the contact section, and arranging the tubular component to enclose the conductor core wire between the inner tubular surface and the outer circumferential surface;and a step of crimping the contact section and the conductor core wire by integral crimping of the tubular component, the conductor core wire and the contact section using a crimping tool designed to deform the tubular component in order to reduce the diameter of the tubular component.

[0009] According to the electrical conductor wire provided with a terminal contact according to the present invention and the method for manufacturing the electrical conductor wire provided with a terminal contact, the tubular component is arranged such that the conductor core wire of the electrical conductor wire is embedded between the outer circumferential surface of the pin-shaped contact section of the terminal contact and the inner tubular surface of the tubular component, and the tubular component presses the conductor core wire to crimp the conductor core wire and the contact section.This means that in the electrical conductor wire with a terminal contact that has this configuration, unlike the known electrical conductor wire with a terminal contact, the terminal contact and the electrical conductor wire are electrically connected without the conductor core being inserted into the contact section of the terminal contact. Therefore, a single terminal contact can be used even if the thickness of the electrical conductor wire or the bundle diameter of the conductor core wire differs for each required specification. If a tubular component with an inner diameter corresponding to the thickness of the electrical conductor wire is used, the electrical conductor wire with a terminal contact can be manufactured.In general, a terminal contact manufactured to match the structure of the mating terminal contact or connector housing is more expensive to produce than a simple tubular component. Even when several types of tubular components with different inner diameters are used, the overall production costs can be reduced by sharing the terminal contact. As described above, the electrical conductor wire provided with a terminal contact according to the present invention and the method for manufacturing the electrical conductor wire provided with a terminal contact can meet a variety of specifications while sharing the terminal contact.

[0010] The present invention is briefly described above. Further details of the present invention will be clarified by reading the embodiments of the invention described below with reference to the accompanying drawings.

[0011] An electrical conductor wire provided with a terminal contact according to an embodiment of the present invention and a method for manufacturing the electrical conductor wire provided with a terminal contact are described below with reference to the drawings. As shown in the Fig. 1 and Fig. As shown in Figure 2, the electrical conductor wire 1, provided with a terminal contact, comprises an electrical conductor wire 10, a male terminal contact 20, and a tubular component 30. The electrical conductor wire 1, provided with a terminal contact, is crimped to a conductor core wire 11 by crimping a contact section 22 of the tubular component 30, which is arranged such that the conductor core wire 11 of the electrical conductor wire 10 is located between an outer circumferential surface of the contact section 22 of the terminal contact 20 and an inner tubular surface of the tubular component 30. Fig. The pair of forms 40 shown in section 6 is included. In this example, the male terminal contact 20 is used, but a female terminal contact 20 can also be used.

[0012] The following description simplifies the process of how in Fig. Figure 1 defines a "front-back direction," an "up-down direction," and a "left-right direction." The "front-back direction," the "up-down direction," and the "left-right direction" are orthogonal to each other. The front-back direction coincides with an axial direction of the terminal contact 20. A radial direction and a circumferential direction of the terminal contact 20 (contact section 22) are simply referred to as the "radial direction" and "circumferential direction," respectively. The components contained in the electrical conductor wire 1, which is provided with a terminal contact, are described in turn.

[0013] First, the electrical conductor wire 10 is described. As in Fig. As shown in Figure 2, the electrical conductor wire 10 comprises the pin-shaped (elongated columnar) metallic conductor core wire 11 and a cylindrical insulating sheath 12 that covers an outer circumference of the conductor core wire 11. The conductor core wire 11 can be formed by bundling a multitude of conductor wires or consist of only a single elongated conductor. At a distal end (front end) of the electrical conductor wire 10, the insulating sheath 12 is removed by the aforementioned terminal contact machining to expose the conductor core wire 11 over a specific length.

[0014] Next, the terminal contact 20 is described. The metallic terminal contact 20 is formed by molding, stamping, or similar processes. The hardness of the metal material from which the terminal contact 20 is made is higher than the hardness of the metal material from which the conductor core wire 11 of the electrical conductor wire 10 is made. As shown in Fig. As shown in Figure 2, the connecting contact 20 is a male connecting contact which has a connecting section 21 located closer to the distal end (front end) and a contact section 22 located closer to the base end (rear end).

[0015] The connecting section 21 is a section that is inserted into a base end of a female mating contact (not shown) and connected to the mating contact, and has, as shown in Fig. Figure 2 shows a massive, column-like shape extending in the front-to-back direction. A distal end (front end) of the connecting section 21 has a shape in which the diameter decreases towards the distal end (so-called tapered shape), so that the connecting section 21 can be easily inserted into the mating contact.

[0016] The contact section 22 is a section in which the exposed conductor core wire 11 of the electrical conductor wire 10 is arranged such that it covers the outer circumferential surface of the contact section 22 and is crimped to the conductor core wire 11, and it has a solid column-like shape that extends in the front-to-back direction before crimping, as shown in Fig. Figure 2 shows that the outer diameter of the contact section 22 is smaller than the outer diameter of the connecting section 21. To easily position the exposed conductor core wire 11 of the electrical conductor wire 10 so that it covers the outer circumferential surface of the contact section 22, a base end (rear end) of the contact section 22 has a shape in which the diameter decreases as it approaches the base end (so-called conical shape). As shown in Fig. As shown in Figure 3, the outer circumferential surface of the contact section 22 is provided with an engagement section 25 which has a non-uniform shape in which annular concave sections 23 and annular convex sections 24 are arranged alternately in the front-back direction.

[0017] As in Fig. As shown in Figure 2, a pair of front and rear flange sections 26 and 27, each extending radially outwards over the entire area in the circumferential direction, are provided at a boundary section between the connecting section 21 and the contact section 22 in the connecting contact 20.

[0018] Next, the tubular component 30 is described. The metallic tubular component 30 is formed by molding, stamping, or similar processes. The hardness of the metal material from which the tubular component 30 is made is higher than the hardness of the metal material from which the conductor core wire 11 of the electrical conductor wire 10 is made. The tubular component 30 has a cylindrical shape extending in the front-to-back direction. The tubular component 30 has an inner tubular surface with an inner diameter that allows the conductor core wire 11 of the electrical conductor wire 10, which is arranged to cover the outer circumferential surface of the contact section 22 of the terminal contact 20, to be enclosed between the inner tubular surface and the outer circumferential surface of the contact section 22.If the thickness of the conductor core wire 11 differs for each required specification of the electrical conductor wire 10, the common terminal contact 20 (contact section 22) is used, and the tubular component 30, which has an inner tubular surface with an inner diameter corresponding to the thickness of the conductor core wire 11 of the electrical conductor wire 10, is selected and used from a variety of tubular component types 30 with different inner diameters. The components contained in the electrical conductor wire 1 with a terminal contact have been described in turn.

[0019] The following describes a method for producing the in Fig. The electrical conductor wire 1, which is provided with a terminal contact, is described in section 1. To manufacture the electrical conductor wire 1 provided with a terminal contact, the following steps are first taken, as shown in section 1. Fig. Figure 2 shows the electrical conductor wire 10, in which the conductor core wire 11 is exposed at the distal end, the terminal contact 20, and the tubular component 30. The tubular component 30 is selected and manufactured from a variety of types with different inner diameters. It has an inner tubular surface with an inner diameter that allows the conductor core wire 11 of the electrical conductor wire 10 to be clamped between the inner tubular surface and the outer circumferential surface of the contact section 22 of the terminal contact 20. The electrical conductor wire 10 is inserted through the tubular component 30, and the tubular component 30 is positioned on the outer circumferential surface of the insulating sheath 12 of the electrical conductor wire 10.

[0020] Next, as indicated by white arrows in Fig. As indicated in Figure 4, the exposed conductor core wire 11 of the electrical conductor wire 10 is arranged on the outer circumferential surface of the contact section 22 such that it covers the outer circumferential surface of the contact section 22 of the terminal contact 20. The conductor core wire 11 is preferably arranged so that it extends over the entire circumferential area of ​​the outer circumferential surface of the contact section 22 of the terminal contact 20. Furthermore, the conductor core wire 11 is preferably arranged on the outer circumferential surface of the contact section 22 such that it covers the engagement section 25 over its entire front-to-back area, which is formed on the outer circumferential surface of the contact section 22.

[0021] Next, as indicated by the white arrow in Fig. As indicated in Figure 5, the tubular component 30, which is arranged on the outer circumferential surface of the insulating sheath 12 of the electrical conductor wire 10, is moved relative to the distal end (front end) with respect to the electrical conductor wire 10 and positioned to cover the conductor core wire 11 of the electrical conductor wire 10, which is arranged on the outer circumferential surface of the contact section 22 of the terminal contact 20. Accordingly, the conductor core wire 11 of the electrical conductor wire 10 is embedded between the outer circumferential surface of the contact section 22 of the terminal contact 20 and the inner tubular surface of the tubular component 30.

[0022] As in Fig. As shown in Figure 6, the two forms 40 are arranged such that they enclose the tubular component 30, which covers the conductor core wire 11 of the electrical conductor wire 10, between them. The two forms 40 are designed such that the entire crimping surfaces 41 have a hexagonal cross-sectional shape during crimping. As shown in Fig. As indicated by white arrows in Figure 6, the two forms 40 are brought relatively close to each other in a left-right direction, and the tubular component 30 is clamped between the two forms 40 in a left-right direction, thereby pressing the crimp surfaces 41 of the two forms 40 against the tubular component 30. Accordingly, the tubular component 30, the conductor core wire 11, and the contact section 22 are integrally crimped, and the tubular component 30 pushes the conductor core wire 11 toward the outer circumferential surface of the contact section 22, thus crimping the contact section 22 of the terminal contact 20 to the conductor core wire 11 of the electrical conductor wire 10 (see also Figure 6). Fig. 7).

[0023] Since the tubular component 30 is made of metal, it possesses sufficient strength and ductility for crimping. Furthermore, the contact section 22 of the terminal contact 20 has a solid, column-like shape. Therefore, the contact section 22 is less likely to deform radially inward during crimping than if it were hollow, allowing the conductor core wire 11 to be pressed firmly against the tubular component 30. When the conductor core wire 11 is pressed against the outer circumferential surface of the contact section 22, it is also pressed against the engagement section 25 formed on the outer circumferential surface of the contact section 22. As a result, the conductor core wire 11 is crimped as shown in Fig. As shown in Figure 8, the conductor core wire 11 is plastically deformed to fill the irregular shape formed by the concave sections 23 and the convex sections 24 of the engagement section 25, thus increasing the contact area between the contact section 22 and the conductor core wire 11. Furthermore, the contact pressure between the contact section 22 and the conductor core wire 11 increases, particularly at a corner portion of a projecting end of the convex section 24. In this case, the plastic deformation of the conductor core wire 11 is due to the fact that the hardness of the metal material of which the conductor core wire 11 is made is lower than the hardness of the metal material of which the tubular component 30 is made and the hardness of the metal material of which the terminal contact 20 is made.Although the irregular shape of the engagement section 25 can be slightly deformed during crimping of the tubular component 30, the engagement section 25 is not deformed to such an extent that the concave section 23 and the convex section 24 are no longer distinguishable from each other. As described above and in . Fig. As shown in Figure 1, the electrical conductor wire 1, which is provided with a connecting contact, is produced in which a crimp section 31 with a hexagonal outer circumferential shape is formed in a part of the tubular component 30 in the front-back direction. < Processes and effects>

[0024] As described above, according to the electrical conductor wire 1 provided with a terminal contact according to the present embodiment and the method for manufacturing the same, the tubular component 30 is arranged such that the conductor core wire 11 of the electrical conductor wire 10 is embedded between the outer circumferential surface of the pin-shaped contact section 22 of the terminal contact 20 and the inner tubular surface of the tubular component 30, and the tubular component 30 presses the conductor core wire 11 in order to crimp the conductor core wire 11 and the contact section 22.This means that in the electrical conductor wire 1 provided with a terminal contact according to the present embodiment, in contrast to the known electrical conductor wire provided with a terminal contact, the terminal contact 20 and the electrical conductor wire 10 are electrically connected without providing a hollow tubular structure in the contact section 22 of the terminal contact. Therefore, even if the thickness of the electrical conductor wire 10 differs for each required specification, the electrical conductor wire 1 provided with a terminal contact can be manufactured using the conventional terminal contact 20 and the tubular component 30 with an inner diameter corresponding to the thickness of the electrical conductor wire 10.In general, the terminal contact 20, which is manufactured to match the structure of the mating terminal contact or the connector housing, is more expensive to produce than the simple tubular component 30. Even if several types of tubular components 30 with different inner diameters are used, the overall production costs can be reduced by sharing the terminal contact 20. Therefore, according to the present embodiment, the electrical conductor wire 1 equipped with a terminal contact can meet a variety of specifications while sharing the terminal contact 20.

[0025] Furthermore, according to the present embodiment, the electrical conductor wire 1, which is provided with a terminal contact, has an engagement section 25 with an uneven shape on the outer circumferential surface of the contact section 22 of the terminal contact 20, and the conductor core wire 11 is pressed against the engagement section 25 and brought into engagement with it. This increases the contact area between the contact section 22 and the conductor core wire 11, thereby improving the reliability of the electrical connection between the terminal contact 20 and the electrical conductor wire 10.

[0026] Furthermore, in the electrical conductor wire 1, which is provided with a connecting contact, the tubular component 30 is made of metal according to the present embodiment. Accordingly, the tubular component 30 has sufficient strength and ductility when, for example, it is crimped to connect the conductor core wire 11 to the contact section 22 of the connecting contact 20.

[0027] Furthermore, in the present embodiment, the contact section 22 of the terminal contact 20 has a solid, column-like shape when used with an electrical conductor 1. Accordingly, when crimping the tubular component 30 to crimp the conductor core wire 11 to the contact section 22 of the terminal contact 20, the contact section 22 is less likely to deform radially inwards than if the contact section 22 were hollow, thus pressing the conductor core wire 11 firmly against the tubular component 30. This improves the reliability of the electrical connection between the terminal contact 20 and the electrical conductor 10. < Other embodiments>

[0028] The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the present invention. For example, the present invention is not limited to the embodiment described above, and modifications, improvements, and the like can be made in a suitable manner. Furthermore, materials, shapes, sizes, number, arrangement positions, and similar aspects of the components in the embodiment described above are freely selectable and not restricted, as long as the present invention can be implemented.

[0029] Here, the features of the embodiment of the electrical conductor wire 1 provided with a terminal contact described above and the method for manufacturing the electrical conductor wire 1 provided with a terminal contact are briefly summarized and listed in [1] to [5].

[0030] [1] An electrical conductor wire (1) comprising a terminal contact: a connection contact (20); an electrical conductor wire (10) to be connected to the terminal contact (20); and a tubular component (30) designed to cover an electrical contact between the terminal contact (20) and the electrical conductor wire (10), wherein the connecting contact (20) has a pin-shaped contact section (22), the electrical conducting wire (10) contains a conductor core wire (11) which is to be electrically connected to the contact section (22), and the tubular component (30) is arranged such that the conductor core wire (11) is embedded between an outer circumferential surface of the contact section (22) and an inner tubular surface of the tubular component (30), and the tubular component (30) is designed such that it pushes the conductor core wire (11) towards the outer circumferential surface of the contact section (22) in order to crimp the contact section (22) and the conductor core wire (11).

[0031] According to the electrical conductor wire provided with a terminal contact according to [1], the tubular component is arranged such that the conductor core of the electrical conductor wire is embedded between the outer circumferential surface of the pin-shaped contact section of the terminal contact and the inner tubular surface of the tubular component, and the tubular component presses the conductor core to crimp the conductor core and the contact section. That is to say, in the electrical conductor wire provided with a terminal contact having this configuration, in contrast to the known electrical conductor wire provided with a terminal contact, the terminal contact and the electrical conductor wire are electrically connected without the conductor core being inserted into the contact section of the terminal contact.Therefore, a single, standardized terminal contact can be used even if the thickness of the electrical conductor wire or the bundle diameter of the conductor core wire differs for each required specification. If a tubular component with an inner diameter matching the thickness of the electrical conductor wire is used, the electrical conductor wire can be fitted with a terminal contact. Generally, a terminal contact manufactured to match the structure of the mating terminal contact or connector housing is more expensive to produce than a simple tubular component. Even when using several types of tubular components with different inner diameters, the overall production costs can be reduced by sharing the same terminal contact.As described above, with this configuration, the electrical conductor wire equipped with a terminal contact can meet a variety of specifications while sharing the terminal contact.

[0032] [2] The electrical conductor wire (1) provided with a terminal contact according to [1], wherein the connecting contact (20) has an engagement section (25) with an uneven shape on the outer circumferential surface of the contact section (22), and the conductor core wire (11) of the electrical conductor wire (10) is pressed by means of the tubular component (30) in order to engage with the engagement section (25).

[0033] According to the electrical conductor wire provided with a terminal contact according to [2], the engagement section has an uneven shape on the outer circumferential surface of the contact section of the terminal contact, and the conductor core wire is pressed against the engagement section and brought into engagement with it. This increases the contact area between the contact section and the conductor core wire and, in particular, increases the contact pressure between the contact section and the conductor core wire at the corner part of the projecting end of the convex section of the engagement section. This improves the reliability of the electrical connection between the terminal contact and the conductor wire.

[0034] [3] The electrical conductor wire (1) provided with a terminal contact according to [1], wherein the tubular component (30) is made of a metallic material.

[0035] In the electrical conductor wire provided with a terminal contact according to [3], the tubular component is made of metal. Accordingly, the tubular component has sufficient strength and ductility when, for example, it is crimped to connect the conductor core wire to the contact section of the terminal contact.

[0036] [4] The electrical conductor wire (1) provided with a terminal contact according to [1], wherein the contact section (22) of the terminal contact (20) has a solid column-like shape.

[0037] According to the electrical conductor wire equipped with a terminal contact as described in [4], the contact section of the terminal contact has a solid, column-like shape. Consequently, when crimping the tubular component to crimp the conductor wire to the contact section of the terminal contact, the contact section is less likely to deform radially inwards than if the contact section were hollow, thus ensuring that the conductor wire is pressed firmly against the tubular component. This can improve the reliability of the electrical connection between the terminal contact and the conductor wire.

[0038] [5] A method for manufacturing an electrical conductor wire (1) provided with a terminal contact, wherein a terminal contact (20) and an electrical conductor wire (10) are electrically connected, the method comprising: a step of arranging a conductor core wire (11) of the electrical conductor wire (10) to cover an outer circumferential surface of a pin-shaped contact section (22) of the terminal contact (20); a step of preparing a tubular component (30) with an inner tubular surface having an inner diameter that allows the conductor core wire (11) to be enclosed between the inner tubular surface and the outer circumferential surface of the contact section (22), and of arranging the tubular component (30) to enclose the conductor core wire (11) between the inner tubular surface and the outer circumferential surface; and a step of crimping the contact section (22) and the conductor core wire (11) by integral crimping the tubular component (30), the conductor core wire (11) and the contact section (22) using a crimping tool (40) designed to deform the tubular component (30) in order to reduce the diameter of the tubular component (30).

[0039] According to the method for manufacturing the electrical conductor wire provided with a terminal contact according to [5], the tubular component is arranged such that the conductor core of the electrical conductor wire is embedded between the outer circumferential surface of the pin-shaped contact section of the terminal contact and the inner tubular surface of the tubular component, and the tubular component presses the conductor core to crimp the conductor core and the contact section. That is to say, in the method for manufacturing the electrical conductor wire provided with a terminal contact with this configuration, in contrast to the prior art, the terminal contact and the electrical conductor wire are electrically connected without the conductor core being inserted into the contact section of the terminal contact.Therefore, a single, standardized terminal contact can be used even if the thickness of the electrical conductor wire or the bundle diameter of the conductor core wire differs for each required specification. If a tubular component with an inner diameter matching the thickness of the electrical conductor wire is used, the electrical conductor wire can be fitted with a terminal contact. Generally, a terminal contact manufactured to match the structure of the mating terminal contact or connector housing is more expensive to produce than a simple tubular component. Even when using several types of tubular components with different inner diameters, the overall production costs can be reduced by sharing the same terminal contact.As described above, a method for manufacturing the electrical conductor wire equipped with a terminal contact using this configuration can meet a variety of specifications while sharing the terminal contact.
