[0001] The present invention relates to a connector for a wire harness. [Background technology]

[0002] BACKGROUND ART A steering electrical connection device including a flat cable wound around a rotating body has been known in the past. This configuration is disclosed in, for example, Patent Document 1.

[0003] In the electrical connecting device disclosed in Patent Document 1, in order to transmit signals from the flat cable wound around the rotating body to the outside, each conductor portion of the flat cable is connected to the core portion of the electric wire by ultrasonic welding. Patent Document 1 refers to this portion as a connecting connector. The other end of the electric wire drawn out from this connecting connector is crimped with a terminal or the like and connected to the connector. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-312568 Summary of the Invention [Problem to be solved by the invention]

[0005] The connector disclosed in Patent Document 1 is merely a relay connector between a group of round electric wires and a flat cable, and is not designed to connect a wire harness consisting of both a group of round electric wires and a flat cable. Therefore, there is a limit to how small the connection structure can be made, and there is room for improvement in this regard.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to realize a connector that can simultaneously connect a group of round electric wires and a flat cable that are included in a wire harness to a mating side.

[0007] The problem to be solved by the present invention is as described above. Next, the means for solving this problem and the effects thereof will be explained.

[0008] According to an aspect of the present invention, there is provided a wire harness connector having the following configuration. That is, this wire harness connector is disposed at an end of a wire harness having a flat cable and a round electric wire. The wire harness connector includes a connector housing, a flat cable connector terminal, and a round electric wire connector terminal. The conductors of the flat cable are connected to the flat cable connector terminal. The conductors of the round electric wire are connected to the round electric wire connector terminal. In the connector housing, a first row, a second row, and a third row, which are rows in which terminal chambers are arranged, are arranged parallel to one another. The first row is a row of terminal chambers into which the flat cable connector terminals are inserted. The second row is a row of terminal chambers into which the round electric wire connector terminals are inserted. The third row is a row of terminal chambers into which the flat cable connector terminals are inserted. The second row is disposed between the first row and the third row.

[0009] This makes it possible to realize a connector that can simultaneously connect the flat cables and the group of round electric wires to their counterparts in a wire harness that is made up of flat cables arranged in pairs and a group of round electric wires arranged between the flat cables.

[0010] The above-mentioned wire harness connector preferably has the following configuration: the connector housing has a first portion, a second portion, and a third portion that are separable from one another; the first row of terminal chambers is arranged at a first boundary between the first portion and the second portion; the second row of terminal chambers is arranged at the second portion; and the third row of terminal chambers is arranged at a second boundary between the second portion and the third portion.

[0011] This allows the connector to accommodate a wide variety of wire harnesses with various shapes or configurations by replacing any of the first, second, and third parts with other shapes. When the first, second, and third parts are separated from each other, the terminal chambers in the first and third rows are both open along their boundaries. Therefore, the flat cable connector terminals can be easily arranged in the terminal chambers in the first row (third row) all at once. As a result, the efficiency of the connection work between the wire harness connector and the flat cable and group of round electric wires is improved, and it is also easy to automate the process.

[0012] The connector for a wire harness preferably has the following configuration: the connector housing has a first portion, a second portion, and a third portion that are separable from one another; the first row of terminal chambers is arranged in the first portion; the second row of terminal chambers is arranged in the second portion; and the third row of terminal chambers is arranged in the third portion.

[0013] This allows the flat cable connector terminals to be easily connected to the first and third rows, and the flat cable connector terminals can be easily connected to the first and third rows.

[0014] The above-mentioned wire harness connector preferably includes a fixing portion that fixes at least one of the first portion and the third portion to the second portion.

[0015] This prevents the wire harness connector from being unintentionally separated.

[0016] The above-mentioned wire harness connector preferably has the following configuration. That is, the connector housing includes a flat cable housing and a round electric wire housing. The flat cable housing and the round electric wire housing are separable from each other. The flat cable housing has a first flat cable portion, a second flat cable portion, and a connecting portion. The first row of terminal chambers is arranged in the first flat cable portion. The third row of terminal chambers is arranged in the second flat cable portion. The connecting portion connects the first flat cable portion and the second flat cable portion. The round electric wire housing is arranged between the first flat cable portion and the second flat cable portion. The round electric wire housing is arranged between the first flat cable portion and the second flat cable portion. The second row of terminal chambers is arranged in the round electric wire housing.

[0017] This allows for a simple configuration with a small number of parts.

[0018] The above-mentioned wire harness connector preferably includes a fixing portion for fixing the flat cable housing to the round electric wire housing.

[0019] This prevents the connector housings from being unintentionally separated. [Brief explanation of the drawings]

[0021] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a wire harness 1 including a wire harness connector 30 according to a first embodiment of the present invention. Fig. 2 is an exploded perspective view of the wire harness connector 30 of the first embodiment.

[0022] A wire harness connector 30 of the first embodiment shown in FIG. 1 is disposed at an end of a wire harness 1 having flat cables 3, 3 and a group of round electric wires 6. The wire harness 1 is provided in, for example, a passenger vehicle, and is electrically connected to on-board equipment, etc. via the wire harness connector 30. In this embodiment, the on-board equipment to which the wire harness 1 is connected is an integrated ECU 80, but is not limited thereto. ECU is an abbreviation for Electronic Control Unit. An integrated ECU refers to an ECU that can control not a single on-board equipment but multiple on-board equipment. Using an integrated ECU can reduce the number of ECUs provided in the passenger vehicle, thereby realizing space savings, etc.

[0023] The wire harness 1 includes a pair of flat cables 3, 3 and a group of round electric wires 6. The wire harness 1 is formed to be elongated, and wire harness connectors 30 are disposed at both ends in the longitudinal direction thereof. In FIG. 1, only one wire harness connector 30 is shown. The wire harness connector 30 can be connected to a connector 90 provided in the integrated ECU 80.

[0024] Each of the pair of flat cables 3, 3 is formed in the shape of an elongated sheet. The cross section of each flat cable 3 cut along a plane perpendicular to the longitudinal direction is substantially flat and rectangular. The flat cable 3 has a known configuration in which a plurality of conductors 4 with rectangular cross sections are arranged in the width direction and covered with an insulating material 5. Each flat cable 3 is flexible. The two flat cables 3 are arranged with a gap between them in the thickness direction.

[0025] The two flat cables 3, 3 are arranged so that one side faces each other in the thickness direction. A group of round electric wires 6 is arranged between the two flat cables 3, 3.

[0026] The round electric wire group 6 is composed of a plurality of round electric wires 7. The round electric wires 7 have a known configuration in which a conductor 8 having a substantially circular cross section is covered with an insulating material 9. The longitudinal direction of each round electric wire 7 is substantially parallel to the longitudinal direction of the flat cable 3 (in other words, the longitudinal direction of the conductor 4).

[0027] The group of round electric wires 6 has at least one row in which the round electric wires 7 are arranged along the direction in which the conductors 4 of the flat cable 3 are arranged. The overall cross-sectional shape of the group of round electric wires 6 is a flat shape that is elongated in the width direction of the flat cable 3. Although FIGS. 1 and 2 illustrate a configuration in which the round electric wires 7 are arranged in two rows, the number of rows of the round electric wires 7 is arbitrary. Since the overall cross-sectional shape of the wire harness 1 of this embodiment is flat as described above, it is suitable for routing in a vertically narrow space, such as a floor locker section of a vehicle.

[0028] The wire harness connector 30 includes a connector housing 31, a plurality of flat cable connector terminals 14, and a plurality of round electric wire connector terminals 18.

[0029] The conductors 4 of the flat cable 3 are connected to the flat cable connector terminals 14. The flat cable connector terminals 14 can be configured as, for example, known piercing terminals, but are not limited to this.

[0030] The conductor 8 of the round electric wire 7 is connected to the round electric wire connector terminal 18. The round electric wire connector terminal 18 can be configured as a known crimp terminal, for example, but is not limited to this.

[0031] The connector housing 31 is made of, for example, synthetic resin. A large number of terminal chambers 32 are formed in the connector housing 31. Each terminal chamber 32 is elongated, and the longitudinal directions of the terminal chambers 32 are parallel to one another. The longitudinal end of each terminal chamber 32 forms an opening in one surface of the connector housing 31. The flat cable connector terminals 14 and the round wire connector terminals 18 are arranged in these terminal chambers 32.

[0032] The connector housing 31 has a first row R1, a second row R2, and a third row R3 in which the terminal chambers 32 are arranged. Each of the first row R1, the second row R2, and the third row R3 consists of one or more rows of terminal chambers 32 arranged in a straight line. The first row R1, the second row R2, and the third row R3 are arranged parallel to one another. In each of the first row R1, the second row R2, and the third row R3, the direction in which the terminal chambers 32 are arranged is perpendicular to the longitudinal direction of the terminal chambers 32. In each of the first row R1, the second row R2, and the third row R3, the direction in which the terminal chambers 32 are arranged substantially coincides with the direction in which the conductors 4 are arranged in the flat cable 3. When viewed along the longitudinal direction of the terminal chambers 32, the second row R2 is arranged between the first row R1 and the third row R3.

[0033] Each of the terminal chambers 32 in the first row R1 is provided with a flat cable connector terminal 14. Each of the terminal chambers 32 in the second row R2 is provided with a round wire connector terminal 18. Each of the terminal chambers 32 in the third row R3 is provided with a flat cable connector terminal 14.

[0034] The connector housing 31 is formed in the shape of a rectangular parallelepiped block as a whole and has a first portion 41, a second portion 42, and a third portion 43 which are separable from one another.

[0035] In other words, the connector housing 31 is divided into a first portion 41, a second portion 42, and a third portion 43 by a first dividing surface (first boundary) P1 and a second dividing surface (second boundary) P2. The first dividing surface P1 and the second dividing surface P2 are arranged parallel to both the direction in which the terminal chambers 32 are arranged in each of the first row R1, the second row R2, and the third row R3, and the longitudinal direction of each terminal chamber 32. The first dividing surface P1 and the second dividing surface P2 are parallel to each other.

[0036] The terminal chambers 32 in the first row R1 are disposed at the boundary between the first portion 41 and the second portion 42. In other words, the first dividing plane P1 that divides the connector housing 31 into the first portion 41 and the second portion 42 is set to include the terminal chambers 32 that belong to the first row R1.

[0037] The terminal chambers 32 in the second row R2 are arranged in the second portion 42. In other words, the terminal chambers 32 in the second row R2 are located between the first dividing surface P1 and the second dividing surface P2.

[0038] The terminal chambers 32 in the third row R3 are disposed at the boundary between the second portion 42 and the third portion 43. In other words, the second dividing plane P2 that divides the connector housing 31 into the second portion 42 and the third portion 43 is set to include the terminal chambers 32 that belong to the third row R3.

[0039] 2, the second portion 42 is integrally formed with a plurality of fixing protrusions 46 for fixing the first portion 41 and the third portion 43. Corresponding to the fixing protrusions 46, the first portion 41 and the third portion 43 are formed with fixing recesses 47 that can be hooked onto the fixing protrusions 46. For example, the fixing protrusions 46 can be formed with claws, and the fixing recesses 47 can be formed as steps. The fixing protrusions 46 and the fixing recesses 47 function as fixing portions that fix the first portion 41 or the third portion 43 to the second portion 42.

[0040] In this embodiment, the operations of connecting the flat cable 3 to the first portion 41, connecting the round electric wire group 6 to the second portion 42, and connecting the flat cable 3 to the third portion 43 can be performed with the connector housing 31 partially separated. Therefore, less work needs to be done in a narrow space, and the assembly work can be simplified.

[0041] For example, it is possible to prepare in advance a plurality of types of second portions 42 each having a different number of second rows R2. In this case, even if the number of round electric wires 7 in the wire harness 1 increases, for example, it is possible to deal with this by simply changing only the second portions 42 to another type. Therefore, it is possible to flexibly carry out design while realizing the standardization of parts.

[0042] As described above, the terminal chambers 32 belonging to the first row R1 and the third row R3 are arranged so as to include the dividing planes P1, P2 of the connector housing 31. Therefore, when the first portion 41 is separated from the second portion 42, all of the terminal chambers 32 in the first row R1 are widely open in a direction perpendicular to the row direction of the first row R1. Similarly, when the third portion 43 is separated from the second portion 42, all of the terminal chambers 32 in the third row R3 are widely open in a direction perpendicular to the row direction of the third row R3. Therefore, as shown by arrow B in FIG. 2 , this large open area can be utilized to install flat cable connector terminals 14 into the terminal chambers 32.

[0043] The flat cable connector terminals 14 arranged in the terminal chambers 32 of the first row R1 and the third row R3 are attached to each of the multiple (three in this embodiment) conductors 4 arranged side by side and integrated in the flat cable 3. Therefore, in a configuration where the flat cable connector terminals 14 are inserted in the longitudinal direction (the direction of arrow A), as in the terminal chambers 32 of the second row R2, multiple flat cable connector terminals 14 must be inserted into the terminal chambers 32 simultaneously. Therefore, even if one of the three flat cable connector terminals 14 is misaligned, all three terminals cannot be inserted, significantly reducing workability. In this regard, in the configuration of this embodiment, the flat cable connector terminals 14 can be assembled to the second portion 42 in the direction of arrow B, making it easy to simultaneously install all of the flat cable connector terminals 14 in one row attached to one flat cable 3. Furthermore, while the flat cable 3 has little longitudinal flexibility, it easily bends in the thickness direction. By utilizing this characteristic, it is easy to correct misalignment when inserting the flat cable connector terminal 14 from the opening into the terminal chamber 32 in the direction of arrow B. Therefore, smooth assembly can be achieved.

[0044] As described above, the wire harness connector 30 of this embodiment is disposed at the end of the wire harness 1 having the flat cable 3 and the round electric wires 7. The wire harness connector 30 includes a connector housing 31, flat cable connector terminals 14, and round electric wire connector terminals 18. Conductors of the flat cable 3 are connected to the flat cable connector terminals 14. Conductors of the round electric wires 7 are connected to the round electric wire connector terminals 18. In the connector housing 31, the terminal chambers 32 are arranged in parallel to one another in rows: a first row R1, a second row R2, and a third row R3. The flat cable connector terminals 14 are inserted into the terminal chambers 32 in the first row R1. The round electric wire connector terminals 18 are inserted into the terminal chambers 32 in the second row R2. The flat cable connector terminals 14 are inserted into the terminal chambers 32 in the third row R3. The second row R2 is disposed between the first row R1 and the third row R3.

[0045] This makes it possible to realize a connector that can accommodate a wire harness 1 that is configured with a pair of flat cables 3, 3 arranged facing each other and a group of round electric wires 6 arranged between the pair of flat cables 3, 3. In addition, since the flat cable 3 and the group of round electric wires 6 can be connected to the mating side at the same time, this contributes favorably to miniaturization of the configuration.

[0046] The wire harness connector 30 of this embodiment has a first portion 41, a second portion 42, and a third portion 43. The first portion 41, the second portion 42, and the third portion 43 are separable from one another. The terminal chambers 32 in the first row R1 are arranged on a first dividing surface P1, which is the boundary between the first portion 41 and the second portion 42. The terminal chambers 32 in the second row R2 are arranged on the second portion 42. The terminal chambers 32 in the third row R3 are arranged on a second dividing surface P2, which is the boundary between the second portion 42 and the third portion 43.

[0047] This allows easy adaptation to design changes in the wire harness 1 by simply changing one or two of the first portion 41, the second portion 42, and the third portion 43. Furthermore, when the first portion 41, the second portion 42, and the third portion 43 are separated from one another, the terminal chambers 32 in the first row R1 and the third row R3 are open along their boundaries. Instead of inserting the flat cable connector terminals 14 along the longitudinal direction of the terminals, the flat cable connector terminals 14 can be collectively placed in the terminal chambers 32 in the first row R1 (third row R3) through the open portions. This improves the efficiency of the connection work between the wire harness connector 30 and the flat cable 3 and the group of round electric wires 6, and also facilitates automation.

[0048] The wire harness connector 30 of this embodiment includes a fixing protrusion 46 and a fixing recess 47. The fixing protrusion 46 and the fixing recess 47 fix the first portion 41 or the third portion 43 to the second portion 42.

[0049] This prevents the wire harness connector 30 from being unintentionally separated.

[0050] Next, a second embodiment will be described. In the following description of this embodiment, the same or similar components as those in the previous embodiment will be denoted by the same reference numerals in the drawings, and the description thereof may be omitted.

[0051] In the second embodiment shown in Fig. 3, the first dividing plane P1 is located between the terminal chambers 32 belonging to the first row R1 and the terminal chambers 32 belonging to the second row R2. Similarly, the second dividing plane P2 is located between the terminal chambers 32 belonging to the second row R2 and the terminal chambers 32 belonging to the third row R3. The rest of the configuration is the same as that of the first embodiment described above.

[0052] 1, it is possible to accommodate a composite wire harness 1 including a flat cable 3 and a group of round electric wires 6, and also possible to accommodate a wide variety of configurations of the wire harness 1. In this embodiment, even when the first portion 41, the second portion 42, and the third portion 43 are separated from each other, the flat cable connector terminal 14 can be reliably maintained in the terminal chamber 32.

[0053] As described above, in the wire harness connector 30 of this embodiment, the terminal chambers in the first row R1 are arranged in the first portion 41. The terminal chambers 32 in the second row R2 are arranged in the second portion 42. The terminal chambers 32 in the third row R3 are arranged in the third portion 43.

[0054] This makes it possible to easily accommodate design changes to the wire harness 1 by simply changing one or two of the first portion 41, the second portion 42, and the third portion 43. Furthermore, even when the first portion 41, the second portion 42, and the third portion 43 are separated from one another, the flat cable connector terminal 14 can be reliably maintained in the terminal chamber 32.

[0055] Next, a third embodiment will be described.

[0056] A wire harness connector 30 of the third embodiment shown in Fig. 4 includes a flat cable housing 51 and a round electric wire housing 52. The flat cable housing 51 and the round electric wire housing 52 are separable from each other.

[0057] The connector housing 31 is divided into a flat cable housing 51 and a round wire housing 52 with a U-shaped dividing plane P3 as the boundary.

[0058] The flat cable housing 51 is configured such that a first flat cable portion 56, a second flat cable portion 57, and a connecting portion 58 are integrally formed.

[0059] The first flat cable portion 56 and the second flat cable portion 57 are formed in a generally plate shape and are arranged parallel to each other.

[0060] A space for accommodating the round electric wire housing 52 is formed between the first flat cable portion 56 and the second flat cable portion 57. In the connector housing 31, the connecting portion 58 is located at one end in the direction in which the terminal chambers 32 are arranged in the first row R1, the second row R2, and the third row R3. The connecting portion 58 connects the first flat cable portion 56 and the second flat cable portion 57 to each other.

[0061] The round electric wire housing 52 has an elongated protrusion 59 formed on each of the surfaces facing the first flat cable portion 56 and the second flat cable portion 57. Correspondingly, the first flat cable portion 56 and the second flat cable portion 57 each have an elongated recess 60 formed on their surfaces facing the round electric wire housing 52. This makes it possible to prevent misalignment when attaching the round electric wire housing 52 to the flat cable housing 51.

[0062] The flat cable housing 51 is formed with a claw-shaped fixing protrusion 66. Correspondingly, the round electric wire housing 52 is formed with a stepped fixing recess 67. The fixing protrusion 66 is caught in the fixing recess 67, thereby maintaining the round electric wire housing 52 attached to the flat cable housing 51.

[0063] The terminal chambers 32 in the first row R1 are arranged in the first portion 56 for the flat cable.

[0064] The terminal chambers 32 in the second row R2 are arranged in the housing 52 for round electric wires.

[0065] The terminal chambers 32 in the third row R3 are arranged in the second portion 57 for the flat cable.

[0066] This configuration can also be used for a composite wire harness 1 including a flat cable 3 and a group of round electric wires 6, as shown in Fig. 1. In this embodiment, the connector housing 31 can be configured with only two components, the flat cable housing 51 and the round electric wire housing 52.

[0067] As described above, in the wire harness connector 30 of this embodiment, the connector housing 31 includes a flat cable housing 51 and a round electric wire housing 52. The flat cable housing 51 and the round electric wire housing 52 are separable from each other. The flat cable housing 51 has a first flat cable portion 56, a second flat cable portion 57, and a connecting portion 58. The first flat cable portion 56 has a first row R1. The second flat cable portion 57 has a third row R3. The connecting portion 58 connects the first flat cable portion 56 and the second flat cable portion 57. The round electric wire housing 52 is disposed between the first flat cable portion 56 and the second flat cable portion 57.

[0068] This allows for a simple configuration with a small number of parts.

[0069] The wire harness connector 30 of this embodiment includes a fixing convex portion 66 and a fixing concave portion 67 for fixing the flat cable housing 51 to the round electric wire housing 52 .

[0070] This prevents the connector housing 31 from being unintentionally separated.

[0071] In the third embodiment described above, the boundary (partition plane P3) dividing the flat cable housing 51 and the round wire housing 52 is set to include the terminal chambers 32 in the first row R1 and the terminal chambers 32 in the third row R3. Therefore, when the round wire housing 52 is separated from the flat cable housing 51, the terminal chambers 32 in the first row R1 and the third row R3 are largely open. Alternatively, the division plane P3 may be set to pass between the terminal chambers 32 in the first row R1 and the third row R3 and the terminal chambers 32 in the second row R2.

[0072] The preferred embodiment of the present invention has been described above, but the above configuration can be modified, for example, as follows. Each modification may be made alone, or multiple modifications may be made in any combination.

[0073] As shown in a first modified example in FIG. 5, the connector housing 31 may be made of a single component without having any separable portions.

[0074] The number of terminal chambers 32 arranged in each of the first row R1, the second row R2, and the third row R3 is arbitrary. At least one of the first row R1, the second row R2, and the third row R3 may be configured with two or more rows of terminal chambers 32.

[0075] The first embodiment can be modified so that a fixing recess is provided in the second portion 42 and fixing protrusions are provided in the first portion 41 and the third portion 43. Similarly, the third embodiment can be modified so that a fixing recess is provided in the flat cable housing 51 and fixing protrusions are provided in the round electric wire housing 52.

[0076] In the first embodiment, the fixing protrusions 46 and the fixing recesses 47 may be omitted. In this case, the first portion 41, the second portion 42, and the third portion 43 may be fixed to one another by an appropriate method, such as by wrapping tape or by adhesive. Similarly, in the third embodiment, the fixing protrusions 59, the recesses 60, the fixing protrusions 66, and the fixing recesses 67 may be omitted.

[0077] In the third embodiment, the connecting portion 58 may be arranged not only on one side but also on both sides in the direction in which the terminal chambers 32 are arranged. In this case, the flat cable housing 51 has a rectangular frame shape, and the round wire housing 52 is inserted into the flat cable housing 51 in a direction parallel to the longitudinal direction of the terminal chambers 32.

[0078] As shown in the second modified example in FIG. 6 , if there are many terminal chambers 32 in the second row R2 into which the round electric wire connector terminals 18 are inserted, a fourth row R4 and a fifth row R5 may be formed in the connector housing 31. The fourth row R4 and the fifth row R5, like the first row R1 and the third row R3, are rows of terminal chambers 32 in which the flat cable connector terminals 14 are arranged. The row direction of the fourth row R4 and the fifth row R5 is perpendicular to the row direction of the first row R1, the second row R2, and the third row R3. In the example of FIG. 6 , the first row R1, the third row R3, the fourth row R4, and the fifth row R5 are arranged in a rectangular shape so as to surround the area of ​​the second row R2. This configuration enables further miniaturization. The connector housing 31 of the second modified example can also be formed in a divided shape, as in the first embodiment.
