A flat cable fixing portion 22 is formed on one side of the housing body 21, and the other side is coupled to a mating connector (not shown, a female connector is applied in this example). For example, the peripheral portion has a shape protruding in a hood shape. And the terminal hole 211 which penetrates between the cable fixing | fixed part 22 and the other one side formed in a hood shape is formed.

  The cover body 23 is formed in a plate shape, and one side thereof is connected to one side of the cable fixing portion 22 of the housing body 21 by a flexible hinge 24. With such a configuration, the housing main body 21 and the cover body 23 can swing relatively around the hinge 24. The cover body 23 can be mounted so as to overlap the cable fixing portion 22 of the housing body 21 by tilting the cover body 23 in the direction of arrow a.

  A pin 231 protrudes from the cover body 23, and a pin hole 221 is formed in the cable fixing portion 22 of the housing body 21. In FIG. 1, substantially cylindrical pins 231 are formed at four locations, one at each of the four corners of the cover body 23, and pin holes 221 having a substantially circular cross section are formed at the four corners of the cable fixing portion 22 of the housing body 21.

  The conductor 11 is formed of a material having good electrical conductivity, such as copper or a copper alloy. The reinforcing material 12 is formed of a material having strength higher than that of the conductor 11, specifically, a stainless steel, for example. The conductor 11 and the reinforcing material 12 are each formed in a thin flat strip shape. The conductors 11 are arranged in parallel with each other at a predetermined interval, and the reinforcing members 12 are arranged in parallel at a predetermined distance from the conductor 11 on both sides thereof.

In addition, a laser may not be used as a means for forming a cut in the insulating coating layer 13, and a cutter such as a cutter may be used.

  The terminal 3 is a member formed in a rod shape from a metal material or the like. In the figure, a configuration including three terminals 3 is shown, but the number and shape thereof are not limited.

  Next, a procedure for assembling the flat cable 1, the connector housing 2, and the terminals 3 will be described. FIG. 2 is an external perspective view showing an assembled state of the connector housing 2a, the flat cable 1a, and the terminal 3. FIG. 2A is a view showing a state in the middle of the assembly, and FIG. 2B is a state after the completion of the assembly. FIG.

  First, the terminal 3 is inserted into the terminal hole 221 of the housing body 21, and one end of the terminal 3 is disposed on the surface of the cable fixing portion 22. Then, the flat cable 1 a is inserted between the cable fixing portion 22 of the housing main body 21 and the terminal 3 located on the surface of the cable fixing portion 22.

  Here, the positional relationship between the pin hole 14 of the flat cable 1a and the pin hole 211 formed in the cable fixing portion 22 of the connector housing 2a is such that the flat cable 1a shown in FIG. The pin hole 14 formed in the flat cable 1a and the pin hole 221 formed in the cable fixing portion 22 are set to coincide with each other. In addition, the pin hole 14 of the flat cable 1a should just be a dimension shape which can insert the pin 231 formed in the cover body 23. FIG. Further, the relationship between the position of the joining window 15 of the flat cable 1a and the position of the terminal hole 211 of the connector housing 2a is the same as that shown in FIG. Each terminal 3 is set on the bonding window 15 where the conductor 11 is exposed. Further, the through hole 222 formed in the cable fixing portion 22 coincides with the position of the conductor 11 when the flat cable 1a is placed, that is, the through hole 222 is positioned below the conductor 11 in the drawing. Formed.

  In the state shown in FIG. 2A, each terminal 3 and the conductor 11 exposed from the joint window 15 of the flat cable 1a are joined. As this joining means, for example, resistance spot welding can be applied. Specifically, the electrode is pressed against the terminal 3 from above in FIG. 2A, and the electrode paired with this electrode is passed through the through hole 222 formed in the cable fixing portion 22 from below in FIG. Push it to 11. In addition, the terminal 3 and the conductor 11 are sandwiched between these electrodes and pressurized, and an electric current is passed.

  After each terminal 3 and each conductor 11 are joined so as to be conductive by such a method, the cover body 23 is tilted in the direction of arrow a and attached to the cable fixing portion 22 of the housing body 21. At this time, the pin 231 of the cover body 23 passes through the reinforcing member 12 of the flat cable 1 a and the pin hole 14 of the insulating coating layer 13 and engages with the pin hole 221 of the cable fixing portion 22. Thereby, as shown in FIG.2 (b), the connector housing 2a is fixed to the flat cable 1a. Note that the assembly order is not limited to the above order. For example, the conductor 11 and the terminal 3 of the flat cable 1a may be joined in advance and then assembled to the connector housing 2a.

  According to such a configuration, when an external force such as a pulling force is applied to the flat cable 1 a, the pulling force is borne by the high-strength reinforcing member 12 and the pin 231 formed on the cover body 23. For this reason, compared with the structure which forms a boss hole and fixes only to the insulation coating layer like the past, the attachment strength of the flat cable 1a and the connector housing 2a improves, and it can prevent the position shift and a fracture | rupture of a flat cable. .

Except for the position, the connector housing 2a according to the first embodiment has substantially the same configuration.

  A pin 231 protrudes from the cover body 23, and a pin hole 221 into which the pin 231 is fitted is formed in the cable fixing portion 22 of the housing body 21. In FIG. 3, a configuration is shown in which one place is formed approximately in the middle of the opposing sides of the cable fixing portion 22 and the cover body 23.

  As shown in FIG. 3, the flat cable 1 b is provided with a reinforcing member 12 for obtaining a coupling strength between the conductor 11 for transmitting a signal, electric power, and the like and the housing 21, similarly to the flat cable 1 a in the first embodiment. The conductor 11 and the reinforcing material 12 are configured to be covered with an insulating coating layer 13. However, the flat cable 1b in the second embodiment has a configuration in which a plurality of conductors 11 are arranged in parallel, and the reinforcing member 12 is arranged between these conductors 11.

That is, external force such as tensile force applied to the flat cable 1 b is borne by the reinforcing material 12 having high strength and the pins 231 formed on the cover body 23. For this reason, the assembly strength of the flat cable 1b and the connector housing 2b is improved as compared with the conventional configuration in which the boss hole is formed and fixed only in the insulating coating layer of the flat cable, and the displacement and breakage of the flat cable are prevented. it can.

And these conductors 11 and 11 'are arrange | positioned in parallel with predetermined spacing, and the sheet-like insulation coating material formed with a synthetic resin material etc. is bonded and integrated from both surfaces of these conductors 11 and 11'. As a result, the conductors 11, 11 ′ are embedded in the insulating coating layer 13.

  Among the plurality of conductors 11 and 11 ′, a pin hole 14 is formed in a specific single conductor or a plurality of conductors (the conductor in which the pin hole 14 is formed is identified by a reference numeral “11 ′”). ). The width dimension of the conductor 11 ′ in which the pin hole 14 is formed (dimension perpendicular to the longitudinal direction of the conductor 11 ′) is formed larger than that of the conductor 11 in which the pin hole 14 is not formed. FIG. 5 shows a configuration in which, out of the five conductors 11 and 11 ′ arranged in parallel, the wide conductor 11 ′ in which the pin hole 14 is formed is arranged one by one on the outermost side.

As in the third embodiment, a pin hole 14 is formed in a specific single or plural conductors 11 ′ among these conductors, and the pin hole 14 is formed in the conductor 11 ′ in which the pin hole 14 is formed. The dimension in the width direction is larger than that of the conductor 11 that is not formed. However, the flat cable 1c according to the third embodiment is configured such that the conductor 11 ′ in which the pin hole 14 is formed is arranged on both sides or one side of the conductor 11 in which the pin hole 14 is not formed. The flat cable 1d in the embodiment includes a configuration in which a conductor 11 ′ in which the pin hole 14 is formed is disposed between the conductors 11 in which the pin hole 14 is not formed. In FIG. 7, one conductor 11 ′ in which the pin hole 14 is formed and four conductors 11 in which the pin hole 14 is not formed are provided on both sides of the conductor 11 ′ in which the pin hole 14 is formed. 14 shows a configuration in which two conductors 11 each having no 14 are arranged.

  In addition, the insulating coating layer 13 is removed to form a joint window 15 at a position where the conductors 11, 11 ′ and the terminal 3 are joined, and the conductors 11, 11 ′ are exposed from the joint window 15. The joint window 15 is formed at the same position not only on the surface (upper side in the drawing) where the terminal 3 is joined but also on the opposite surface. As the means for forming the joint window 15, the same means as those shown in the first embodiment can be applied, and the description thereof will be omitted.

  As shown in FIG. 7, the connector housing 2d includes a housing main body 21 and a cover body 23, and is integrally formed of, for example, a synthetic resin material. Except for the number and position of the pins 231 formed in the cover body 23 and the numbers and positions of the through holes 222 and the pin holes 221 formed in the cable fixing portion 22 of the housing body 21, the first to third. Since it has substantially the same configuration as the connector housings 2a, 2b, 2c in the embodiment, the description thereof is omitted.

  A pin 231 protrudes from the cover body 23 on the surface that is attached to the cable fixing portion 22, and a pin hole into which the pin 231 is fitted when the cover body 23 is attached to the cable fixing portion 22. 221 is formed. In FIG. 7, one pin 231 is formed in the middle of the opposite sides of the cover body 23, and one pin hole 221 is formed in the approximate center of the opposite sides of the cable fixing portion 22. The configuration is shown.

  FIG. 8 is an external perspective view showing the assembled state of the connector housing 2d, the flat cable 1d, and the terminal 3. FIG. 8A is a view showing a state during the assembly, and FIG. 8B is a state after the completion of the assembly. FIG. 8 (a) and 8 (b) correspond to FIGS. 2 (a) and 2 (b), respectively, referred to in the description of the first embodiment, and such a flat cable 1c and connector housing 2c. Since the procedure for assembling the terminal 3 is substantially the same as the procedure shown in the first to third embodiments, the description thereof is omitted.

  According to such a configuration, when an external force such as a tensile force is applied to the flat cable, the tensile force is borne by the conductor 11 ′ in which the pin hole 14 is formed and the pin 231 formed in the cover body 23. It will be. For this reason, the flat cable 1d and the connector housing 2d can be firmly coupled as compared with the configuration in which the pin hole 14 is formed and coupled only to the insulating coating layer 13 of the flat cable. Here, the conductor 11 ′ in which the pin hole 14 is formed is formed to have a larger width direction dimension and higher in strength than the conductor 11 that is not formed, and therefore, the coupling between the flat cable 1 d and the connector housing 2 d is stronger. Become.

  Furthermore, when power or an electrical signal is actually transmitted through the conductor 11, the conductor 11 'in which the pin hole 14 is formed is wider than the conductor 11 in which the pin hole 14 is not formed. Therefore, the pin hole 14 is formed in the conductor 11'. Even if it is formed, it is possible to secure a sufficient cross-sectional area for transmitting electric power and electric signals, and to suppress heat generation due to an increase in resistance.

  In addition, in each said embodiment, although demonstrated using the example applied to the connector housing of the wire harness for motor vehicles, if it is a connector housing, it can apply, without a use being limited. Further, the electric / electronic member is not limited to the connector housing, but can be applied to a printed circuit board and a flexible circuit board.
