Description

[Technical Field]

[0001] The present invention relates to a connector, and more particularly to a connector and connector assembly for electrically connecting a conductor portion of an electric wire to a contact portion exposed on the back surface of a sheet-like connection object. The present invention also relates to a connection method for electrically connecting a conductor portion of an electric wire to a contact portion exposed on the back surface of a sheet-like connection object. [Background technology]

[0002] In recent years, so-called smart clothing has been attracting attention because it can acquire a user's biometric information, such as heart rate and body temperature, simply by wearing the clothing. This smart clothing is equipped with electrodes made of flexible conductors that are placed at measurement locations, and by electrically connecting a wearable device acting as a measuring instrument to the electrodes, it becomes possible to transmit the biometric information to the wearable device. The electrodes can be connected to the wearable device, for example, by using a connector connected to a flexible conductor.

[0003] However, if the wearable device is located far from the measurement location, an electrical path must be constructed from the electrode placed at the measurement location to the connector attachment position. If such an electrical path is formed using a flexible conductor, the electrical resistance will be high and the cost will be high. Therefore, in order to connect electrodes made of flexible conductors to wearable devices using inexpensive wires with low electrical resistance, there is a need for the development of a small connector that can connect wires to flexible conductors placed in clothing.

[0004] As a connector for connecting an electric wire to a flexible conductor, for example, Patent Document 1 discloses a connector as shown in Fig. 19. This connector has a first connector 2 connected to an end of a substrate 1 and a second connector 4 attached to the tip of an electric wire 3, and by fitting the second connector 4 into the first connector 2, the electric wire 3 can be connected to the flexible conductor of the substrate 1.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. A connector assembly according to an embodiment is shown in Fig. 1. The connector assembly is configured such that conductor portions 31A of a plurality of coated electric wires 31 are connected to a sheet-like connection target 21 using a connector 11. The connector 11 includes an insulator 12 that is made of an insulating resin material and has a substantially flat plate shape, and a plurality of metal terminals 13 that are held by the insulator 12 .

[0018] The multiple covered electric wires 31 are arranged in a predetermined arrangement direction, and each extends parallel to the surface of the insulator 12 of the connector 11 in a direction perpendicular to the arrangement direction. Each covered electric wire 31 has a structure in which the outer periphery of a conductor portion 31A is covered with an insulating covering portion 31B. The connector 11 electrically connects the conductor portions 31A of the multiple covered electric wires 31 to multiple contact portions (described later) exposed on the back surface of the connection target 21. The conductor portion 31A of the covered electric wire 31 may be either a so-called solid wire, which is composed of a single conductor, or a so-called twisted wire, which is composed of multiple conductors twisted together.

[0019] For convenience, the insulator 12 of the connector 11 extends along the XY plane, the arrangement direction of the multiple covered electric wires 31 is called the X direction, the direction in which each covered electric wire 31 extends toward the connector 11 is called the +Y direction, and the direction perpendicular to the XY plane is called the Z direction.

[0020] As shown in FIGS. 2 to 4, insulator 12 of connector 11 has a rectangular shape that extends along the XY plane and is elongated in the X direction, and has flat surface 12A that extends along the XY plane and faces the +Z direction.

[0021] Wall portions 12B protruding in the +Z direction are formed at the −X direction end, +X direction end, and −Y direction end of insulator 12, and a plurality of wire accommodating grooves 12C arranged in the X direction are formed at the −Y direction end of insulator 12. The plurality of wire accommodating grooves 12C correspond to the plurality of insulated electric wires 31, extend in the Y direction across wall portions 12B, are recessed from flat surface 12A in the −Z direction, and have a groove width in the X direction corresponding to the diameter of the insulated electric wire 31.

[0022] Further, in the vicinity of the end portion in the +Y direction of the insulator 12, a plurality of protrusions 12D are formed, which are arranged in the X direction and each protrude in the +Z direction. The insulator 12 has a through hole 12E formed therein, which penetrates the insulator 12 in the Z direction, at a position adjacent to the -Y direction side of the plurality of protrusions 12D arranged in the X direction. The through hole 12E extends in the X direction so as to cover the entirety of the plurality of protrusions 12D arranged in the X direction.

[0023] Furthermore, a plurality of metal terminals 13 are exposed on the flat surface 12A at positions adjacent to the through-hole 12E on the −Y direction side. As shown in Figure 3, the multiple wire accommodating grooves 12C, the multiple protrusions 12D, and the multiple metal terminals 13 are each arranged in the X direction at an arrangement pitch P1, and when viewed from the Z direction, the corresponding wire accommodating grooves 12C, protrusions 12D, and metal terminals 13 are arranged in a straight line along the Y direction.

[0024] As shown in Figures 5 and 6, metal terminal 13 is made of a bent metal plate and has a flat plate portion 13A extending along the XY plane, a spring portion 13B connected to the +Y direction end of flat plate portion 13A, and a bottom plate portion 13D connected to the -Y direction end of flat plate portion 13A via step portion 13C and extending along the XY plane. The flat plate portion 13A has a surface 13E facing the +Z direction, and two protrusions 13F are formed on the surface 13E so as to protrude in the +Z direction. The two protrusions 13F each extend along the X direction and are spaced apart from each other in the Y direction.

[0025] Spring portion 13B forms a pressing portion that presses sheet-like connection object 21 against conductor portion 31A drawn out from coated electric wire 31, and is formed from rising portion 13G that rises from the +Y direction end of flat plate portion 13A toward the +Z direction, and arm portion 13H that bends from the +Z direction end of rising portion 13G and extends in the -Y direction. Due to such rising portion 13G and arm portion 13H, spring portion 13B has a cantilever shape that protrudes from flat plate portion 13A in the +Z direction and extends in the -Y direction (first direction).

[0026] A slit 13J is formed in the center of the spring portion 13B in the X direction, from the −Z direction end of the rising portion 13G connected to the flat plate portion 13A to near the −Y direction end of the arm portion 13H. Furthermore, a curved portion 13K that curves toward the +Z direction is formed at the −Y direction end of the spring portion 13B. Furthermore, the bottom plate portion 13D is disposed at a position shifted toward the −Z direction side from the flat plate portion 13A due to the presence of the step portion 13C.

[0027] 7 and 8, the metal terminal 13 is held by the insulator 12 so that the surface 13E of the flat portion 13A is flush with the flat surface 12A of the insulator 12 and is exposed in the +Z direction. The flat surface 12A of the insulator 12 and the surface 13E of the flat portion 13A of the metal terminal 13 form a conductor portion arrangement surface S on which the conductor portion 31A of the coated electric wire 31 is arranged. The conductor portion arrangement surface S extends in the X direction (third direction) along the flat surface 12A of the insulator 12.

[0028] The spring portion 13B of the metal terminal 13 protrudes in the +Z direction from the conductor portion arrangement surface S, and the +Y direction end of the spring portion 13B is located above a through hole 12E that penetrates the insulator 12 in the Z direction. The stepped portion 13C of the metal terminal 13 is embedded in the insulator 12, and the lower surface of the bottom plate portion 13D on the -Z direction side is flush with the lower surface of the insulator 12 and is exposed in the -Z direction from the insulator 12. The bottom of the wire accommodating groove 12C of the insulator 12 is formed by the bottom plate portion 13D of the metal terminal 13.

[0029] 9, the height H1 in the Z direction from the surface on the +Z direction side of the bottom plate portion 13D of the metal terminal 13 that forms the bottom of the wire accommodating groove 12C of the insulator 12 to the conductor portion arrangement surface S is set to be approximately equal to the thickness of the insulating coating portion 31B that covers the outer periphery of the conductor portion 31A of the insulated wire 31. Therefore, when the insulated wire 31 is accommodated in the wire accommodating groove 12C with the conductor portion 31A pulled out from the tip of the insulated wire 31, the insulating coating portion 31B is arranged on the bottom plate portion 13D of the metal terminal 13, and the conductor portion 31A pulled out from the insulating coating portion 31B is arranged on the conductor portion arrangement surface S.

[0030] For example, the connector 11 having such a configuration in which the plurality of metal terminals 13 and the insulator 12 are integrated can be produced by insert molding.

[0031] A sheet-like connection object 21 is shown in Fig. 10. The connection object 21 has a multi-layer structure in which, for example, at least one wiring layer made of a conductor and a plurality of insulating layers are stacked. The connection object 21 extends along the XY plane, and the surface facing the +Z direction is covered with an insulating layer 21A. Further, a plurality of openings 21B are formed near the -Y direction end of the connection object 21, arranged in the X direction and each penetrating the connection object 21 in the Z direction. The openings 21B have a size that allows the spring portions 13B of the metal terminals 13 that protrude in the +Z direction from the conductor portion arrangement surface S of the connector 11 to pass through in the Z direction.

[0032] 11, a plurality of contact portions 21C are exposed on the back surface of the connection object 21 facing the -Z direction, and are arranged in the X direction along the -Y direction end of the connection object 21. The plurality of contact portions 21C correspond to the plurality of openings 21B, and the plurality of openings 21B are arranged adjacent to the plurality of contact portions 21C on the +Y direction side. That is, the contact portions 21C corresponding to the -Y direction side of the openings 21B are arranged adjacent to each other at the same X direction position as the openings 21B. The openings 21B and contact portions 21C are arranged in the X direction at an arrangement pitch P1, similar to the wire receiving grooves 12C, protrusions 12D and metal terminals 13 of the connector 11. The plurality of contact portions 21C are formed from a part of one wiring layer of the connection object 21, and are connected to a plurality of wiring portions (not shown) covered by the insulating layer 21D.

[0033] When assembling the connector assembly, first, as shown in Figure 12, multiple coated electric wires 31 are arranged in the X direction, the insulating coating portion 31B of each coated electric wire 31 is accommodated in the corresponding wire accommodating groove 12C of the insulator 12 of the connector 11, and the conductor portion 31A pulled out from the insulating coating portion 31B is placed on the conductor portion arrangement surface S of the connector 11 from the -Y direction.

[0034] At this time, as shown in Figure 13, the conductor portion 31A extends in the +Y direction on the conductor portion arrangement surface S formed by the flat surface 12A of the insulator 12 and the surface 13E of the flat portion 13A of the metal terminal 13, and is positioned on two protrusions 13F of the metal terminal 13. As shown in FIG. 14, the conductor portion 31A is disposed between the conductor portion arrangement surface S and the spring portion 13B in a state in which the conductor portion 31A penetrates the slit 13J formed in the spring portion 13B of the metal terminal 13 in the Y direction.

[0035] 15, the sheet-like connection object 21 extending from the +Y direction (second direction) toward the conductor portion arrangement surface S of the connector 11 is placed on the connector 11 with its back surface facing the conductor portion arrangement surface S. The connection object 21 is aligned with the connector 11 so that the multiple openings 21B are positioned directly above the spring portions 13B of the multiple metal terminals 13 of the connector 11, as shown in FIG.

[0036] At this time, as shown in Figure 17, the portion of the connection object 21 on the +Y side of the opening 21B contacts the convex portion 12D of the insulator 12 of the connector 11, and the portion on the -Y side of the opening 21B is positioned on the conductor portion 31A arranged on the conductor portion arrangement surface S. In addition, a curved portion 13K formed at the -Y direction end of the spring portion 13B of the metal terminal 13 of the connector 11 and curved toward the +Z direction is positioned on the +Z direction side of the connection object 21 through the opening 21B of the connection object 21.

[0037] 18, by pulling the connection object 21 in the +Y direction, the connection object 21 is displaced in the +Y direction relative to the connector 11. Here, since the curved portion 13K of the spring portion 13B of the metal terminal 13 of the connector 11 is positioned on the +Z direction side of the connection object 21 through the opening 21B, the portion of the connection object 21 adjacent to the -Y direction side of the opening 21B, which displaces in the +Y direction relative to the spring portion 13B, enters the -Z direction side of the spring portion 13B while pushing the spring portion 13B apart.

[0038] As a result, the connection object 21 is sandwiched between the spring portion 13B passed through the opening 21B and the conductor portion 31A placed on the conductor portion placement surface S, and due to the elastic force of the spring portion 13B, the contact portion 21C exposed on the back surface of the connection object 21 comes into contact with the conductor portion 31A with a predetermined contact pressure, and is electrically connected to the conductor portion 31A.

[0039] As the connection object 21 is displaced in the +Y direction, the opening 21B of the connection object 21 moves to the position of the protrusion 12D of the insulator 12 of the connector 11, and the protrusion 12D is inserted into the opening 21B. In this way, the assembly of the connector assembly is completed.

[0040] The connector 11 has a simple structure in which a plurality of metal terminals 13 are held by a substantially flat insulator 12, making it possible to realize a thin connector 11 and a thin connector assembly.

[0041] Furthermore, the conductor portion 31A pulled out from the coated electric wire 31 is positioned between the conductor portion placement surface S and the spring portion 13B while passing through the slit 13J formed in the spring portion 13B of the metal terminal 13, thereby preventing the conductor portion 31A from shifting position relative to the metal terminal 13 and further preventing the conductor portion 31A from coming into contact with an adjacent metal terminal 13 and causing a short circuit. Furthermore, since the metal terminal 13 is held by the insulator 12 so that the +Y-direction end of the spring portion 13B is positioned above the through-hole 12E of the insulator 12, it is possible to visually confirm through the through-hole 12E from the -Z-direction side of the connector 11 that the +Y-direction end of the conductor portion 31A of the coated electric wire 31 passes through the slit 13J of the spring portion 13B of the metal terminal 13, as shown in Figures 17 and 18. This improves the reliability of the connection of the plurality of coated electric wires 31 to the connection object 21.

[0042] In the above embodiment, the multiple metal terminals 13 are held in the insulator 12 by insert molding, but this is not limited to this, and the multiple metal terminals 13 can also be held in the insulator 12 by, for example, press-fitting.

[0043] Furthermore, in the above embodiment, the spring portion 13B of the metal terminal 13 held by the insulator 12 forms a pressing portion that presses the sheet-shaped connection object 21 against the conductor portion 31A of the insulated electric wire 31, but this is not limited to this, and the connection object 21 can also be configured to be pressed against the conductor portion 31A of the insulated electric wire 31 using a cantilever-shaped pressing portion formed integrally with the insulator 12 using the insulating resin material that constitutes the insulator 12.

[0044] The sheet-like connection object 21 may be either a flexible substrate or a rigid (hard) substrate. In the above embodiment, the conductor portions 31A of the plurality of insulated electric wires 31 are placed on the conductor portion placement surface S of the connector 11 from the -Y direction, and then the connection object 21 is placed on the connector 11 so that the plurality of openings 21B of the connection object 21 are positioned directly above the spring portions 13B of the plurality of metal terminals 13 of the connector 11, and the connection object 21 is pulled in the +Y direction, whereby the plurality of contact portions 21C exposed on the back surface of the connection object 21 are electrically connected to the conductor portions 31A of the plurality of insulated electric wires 31. Therefore, even if a flexible substrate is used as the connection object 21, there is no need to reinforce the flexible substrate with a reinforcing plate or the like, and it is possible to reliably electrically connect the plurality of contact portions of the flexible substrate to the conductor portions 31A of the plurality of insulated electric wires 31.

[0045] Furthermore, by forming the insulator 12 of the connector 11 from a flexible material such as rubber and using a flexible substrate as the connection object 21, it is possible to construct a connector assembly that can deform, for example, along the arrangement direction of the multiple coated electric wires 31.

[0046] In the above embodiment, the conductor portions 31A of the multiple coated electric wires 31 are connected to the multiple contact portions 21C of the connection object 21, but this is not limited to this, and a connector assembly can also be constructed in a similar manner in which the conductor portion 31A of a single coated electric wire 31 is connected to the contact portion 21C of the connection object 21. In addition, although a coated electric wire 31 is used as the electric wire to be connected to the connection object 21, an electric wire having only a conductor portion 31A whose outer periphery is not covered by an insulating coating portion 31B can also be connected to the connection object 21.
