Description

  The present invention relates to a light emitting component mounting flat cable fixing structure for fixing to a support a light emitting component mounting flat cable on which a light emitting component such as a light emitting component lamp to be assembled in a vehicle is mounted.

In recent years, in a vehicle such as an automobile, a large number of light emitting components are used for lamps in a front part and a rear part. An electric wire, a bus bar, a printed wiring board, or the like is used as a power supply wiring material for the light emitting component.
For example, in Patent Document 1, a large number of light-emitting components are three-dimensionally arranged in a staircase shape, and a normal electric wire, that is, an insulating coated electric wire in which an insulating coating is applied to a conductor having a circular cross section, is connected as a power supply line. A lamp is disclosed.

  By the way, as a vehicular lamp, there is a lamp in which a large number of light emitting parts are arranged in a ring shape and a light collecting reflector is arranged around the light emitting parts. In the vehicular lamp using the light-emitting component, a large number of bus bars are fixed to the outer peripheral surface of the annular support at intervals in the circumferential direction, the light-emitting components are connected so as to straddle adjacent bus bars, and the bus bar is connected to the circuit board. Soldered to. The lead of the light emitting component and the bus bar are connected by cold welding.

  In addition to the vehicle lamps described above, light emitting parts are also used for patrol cars, warning lights for road construction signs, and the like. In general, the above-described normal electric wire, that is, an insulation-coated electric wire having a circular cross section is used for connection with the light emitting component leads in these warning lights.

Generally, a light emitting component used as a lamp is a heating element. Therefore, it is necessary to take heat dissipation measures to maintain stable light emission for a long time. As a heat dissipation method for light-emitting parts, it is common to release heat generated from the light-emitting parts to the power supply line side. However, if the power supply line is a normal insulation-coated electric wire with a circular cross section, its surface area is larger than the conductor cross-sectional area. The heat dissipation characteristics are not so good because of its small size.
On the other hand, the bus bar has a larger surface area than the above-mentioned insulation-coated electric wire with a circular cross section, and therefore has better heat dissipation characteristics, but it requires a metal plate to be processed into a complicated shape, and it takes time to assemble and costs. There is a problem that becomes high.

  Therefore, a flat cable, that is, a cable in which a thin flat conductor, specifically, a copper tape conductor is covered with an insulating film such as a PET (polyethylene terephthalate) film (hereinafter simply referred to as a flat cable) is used as a power supply line to the light emitting component. The proposal used (the applicant's own application: Japanese Patent Application No. 2004-059416) has also been made.

This is one in which a light-emitting component mounting flat cable on which a plurality of light-emitting components are mounted at a predetermined interval in the longitudinal direction of the flat cable is fixed to an annular support.
By mounting the light emitting component on the flat cable in this way, the surface area of the conductor becomes larger than that of a conventional conductor having a circular cross section, and as a result, the heat generated by the light emitting component can be radiated efficiently, and the flat cable is flexible. Because of its superiority, it is easy to assemble and reduce costs.

  By the way, when a lamp using a light-emitting component is used as a vehicle lamp, the vehicle is constantly subjected to large vibrations, so how to fix the light-emitting component-equipped flat cable to the support is a very important issue. . However, the applicant's own prior application does not mention this problem in detail.

Therefore, the present applicant first tried fixing the light-emitting component-equipped flat cable to the support by the method shown in FIGS. 12 and 13, which is generally a method of fixing a film-like material such as a flat cable to the support.
In FIG. 12, reference numeral 20 denotes a flat cable, which is obtained by covering the top and bottom of a conductor 26 made of copper tape with insulating films 28 and 28 such as PET films. In FIG. 12, only one light emitting component 22 is mounted on the flat cable 20, but actually a large number of light emitting components 22 are mounted at predetermined intervals in the longitudinal direction of the flat cable 20.
The leads 34, 34 of the light emitting component 22 extend on the conductors 26, 26 (shown by dotted lines) of the flat cable 20, and are fixed to the flat cable 20 by connection members 23 that are in surface contact with the leads 34, The conductors 26 and 26 of the flat cable 20 are mechanically and electrically connected.

The lead 34 of the light emitting component 22, the connection member 23, and the conductor 26 of the flat cable 20 are electrically connected.

In this way, when the flat cable 20 having the plurality of light emitting components 22 mounted in the longitudinal direction is fixed to the surface of the support 29, the conductor 26 of the flat cable 20 does not exist in advance, for example, on both sides of the flat cable 20. Punch holes 30 are provided at a predetermined interval, and fixing pillars 31 corresponding to the punch holes 30 and penetrating through the punch holes 30 are provided in advance on the other support body 29 side. 31 is passed through the punch hole 30. After that, for example, the head of the fixing column 31 is heated and melted and crushed by an electric iron-shaped heating means, as shown in FIG. 13, and the flat cable 20 on which the light emitting component 22 is mounted is fixed to the surface of the support 29. To do.
Incidentally, FIG. 13 is a sectional view showing a state in which the flat cable 20 is fixed to the support 29.

  However, in the case of the method of fixing the flat cable 20 to the support 29 in this way, it is necessary to provide a plurality of punch holes 30 at predetermined intervals on both sides in the longitudinal direction of the flat cable 20 in addition to the punch holes 30. There is a problem that, after passing through the fixing column 31, the work of crushing the head by heating means is complicated and difficult to perform. In addition, during the operation, there is a risk that the heating means may melt and damage not only the head of the fixing column 31 but also other parts such as the surface of the flat cable 20.

  As described above, according to the present invention, when a flat cable on which a light emitting component is mounted is fixed to a support, there is no risk of melting and damaging the surface of the flat cable or the like, and the light emitting component mounting that can be easily fixed. A flat cable fixing structure can be provided.

A light emitting component mounting flat cable fixing structure according to an embodiment of the present invention will be described below in detail with reference to the drawings.
FIG. 1 is an exploded perspective view showing an embodiment of a fixing structure of a light emitting component mounting flat cable according to the present invention. Reference numeral 20 is the same as the flat cable shown in FIG. 12. For example, two conductors 26 made of copper tape having a thickness of 0.15 mm and a width of 5.2 mm are arranged in parallel at an interval, and this is PET (polyethylene). The film is covered with insulating films 28 and 28 made of a terephthalate film or the like from both the upper and lower surfaces.

On the flat cable 20, a light emitting component 22 such as an LED (light emitting diode) is disposed. On both sides of the lower part of the light emitting component 22, plate-like leads 34, 34 extend in a direction away from each other, and are positioned over the conductors 26, 26.
A plastic support 29 is disposed below the flat cable 20. A fixed terminal insertion hole block 15 is formed on the surface of the support 29. The fixed terminal insertion hole block 15 is provided with a fixed terminal insertion hole 14 into which the fixed terminal 12 of the connection member 10 is inserted.
The light emitting component 22, the flat cable 20, and the support 29 are overlapped with each other as described above, positioned, and mechanically connected and fixed to each other by the connection member 10.

  As shown in an enlarged view of an example in FIG. 3, the connecting member 10 is a flat piece 11 that is in electrical contact with the lead 34 of the light emitting component 22, and extends from the end of the flat piece 11. A piercing terminal 13 for piercing connection (through connection) to the conductor 26 of the cable 20 and a fixed terminal 12 extending from the end of the planar piece 11 and fixing the flat cable 20 to the support 29 are provided. . The tip of the fixed terminal 12 has an arrow shape. The fixed terminal 12 and the pierce terminal 13 are both extended from the end of the planar piece 11 and are bent in the same direction with respect to the planar piece 11, in this example, at a substantially right angle.

In order to connect the light emitting component 22 to the flat cable 20 with the connecting member 10 and fix the flat cable 20 on which the light emitting component 22 is mounted in this manner to the support 29, first, as shown in FIG. The 22 leads 34 and 34 are positioned so as to straddle the conductors 26 and 26 indicated by dotted lines of the flat cable 20.
Thereafter, the fixed terminal 12 and the pierced terminal 13 of the connecting member 10 are faced downward, and the planar piece 11 is placed on the lead 34 of the light emitting component 22 so as to be in surface contact with the fixed terminal 12 and the pierced terminal 13. Are respectively passed through the flat cable 20.
A crimp portion 13a is formed by bending and curling the tip of the penetrating pierce terminal 13 inward, thereby crimping the flat cable 20 and electrically connecting the connecting member 10 and the conductor 26 of the flat cable 20 to each other. .
Thus, the light emitting component 22 is fixed to the flat cable 20 by the lead 34 being sandwiched and fixed between the connecting member 10 and the flat cable 20. As a result, the connection member 10 and the lead 34 are brought into surface contact and electrically connected.
Therefore, the light emitting component 22, the flat cable 20, and the connecting member 10 are electrically connected to each other and mechanically fixed.

Further, for the connection member 10 that connects the light emitting component 22 and the flat cable 20 in this way, for the fixed terminal insertion hole provided at the support 29 with the tip of the fixed terminal 12 penetrating and protruding from the back surface of the flat cable 20. The fixed terminal 12 is inserted into the fixed terminal insertion hole 14 of the block 15, and the fixed terminal 12 is coupled to the support 29.
At this time, the two adjacent crimp portions 13 a and 13 a are both housed in the space between the walls of the adjacent fixed terminal insertion holes 14 of the fixed terminal insertion hole block 15.
Here, since the tip of the fixed terminal 12 has an arrow shape, it can be easily inserted when inserted into the fixed terminal insertion hole 14, and after insertion, the base of the arrow shape, that is, the base of the triangle is fixed. It becomes easy to get caught on the edge of the terminal insertion hole 14, and it becomes difficult to come off.
Thus, the flat cable 20 on which the light emitting component 22 is mounted is fixed to the support 29.

In the present embodiment, after fixing the light emitting component 22, the flat cable 20, and the support body 29 in this order by the connecting member 10, the upper portion of the planar piece 11 of the connecting member and the lead 34 of the light emitting component 22 is further provided. A shear stress is applied to the located part from the upper side, and the dent 18 is formed.
2 is a cross-sectional view taken along line AA in FIG. As shown in FIG. 2, when the recess 18 is formed, a shearing portion 19 is formed in which the planar piece 11 of the connection member 10, the lead 34 of the light emitting component 22, and a part of the flat cable 20 are sheared. At this time, the planar piece 11 of the connecting member 10 and the lead 34 are reliably connected mechanically and electrically.
In order to form such a shearing portion 19, a predetermined area is required at a location where processing is performed, and from the viewpoint of ease of processing, the lead 34 is preferably a plate-like member.
The shearing portion 19 will be described again with reference to FIG.

As described above, according to the fixing structure of the light emitting component mounting flat cable of the embodiment of FIGS. 1 and 2, the light emitting component 22, the flat cable 20 and the support 29 are mechanically connected and fixed by the same connecting member 10. Therefore, the flat cable 20 on which the light emitting component 22 is mounted can be easily attached to the support 29, and there is no fear that the surface of the flat cable or the like is melted and damaged as in the conventional case.
In particular, when the connecting member 10 has a structure including the planar piece 11 that is in electrical contact with the lead 34 of the light emitting component 22, the fixed terminal 12, and the pierce terminal 13, as shown in FIG. 3, the pierce terminal 13. Thus, the connecting member 10 is connected to the conductor 26 of the flat cable 20, and at the same time, the flat cable 20 can be mechanically fixed to the support 29 by the fixing terminal 12. That is, the light emitting component 22, the flat cable 20, and the support 29 can be reliably and easily connected and fixed by the same connecting member 10, which is preferable.

Further, since the fixed terminal insertion hole block 15 is formed at a predetermined height, the crimp portion 13a and the shearing portion 19 of the pierce terminal 13 are spaced from the support 29, that is, fixed in a floating state. Yes.
Accordingly, the reaction force from the support 29 caused by the fixation of the fixed terminal 12 does not have to be received by the connection portion between the pierce terminal 13 or the recess 18 and the flat cable 20. As a result, deterioration of these connecting portions can be prevented, which is preferable.
Further, as described above, since the protrusions called the fixed terminal insertion hole blocks 15 are provided at predetermined positions on the surface of the support body, the positioning of the light emitting component 22 on the flat cable 20 is facilitated, which is preferable.

As the connecting member 10, in addition to those shown in FIGS. 1 and 3, for example, there is a shape shown in FIGS. 4 and 5. In addition, it is assumed that the shape of the fixed terminal insertion hole block 15 of the support 29 is appropriately changed with respect to the modified examples of the connection member 10.
The connecting member 10 shown in FIG. 4 is characterized in that the tip of the fixed terminal 12 has an arrow shape, and this arrow type includes a split 16 of a predetermined length from the tip of the arrow shape in the axial direction of the fixed terminal 12. There is in point.
When the slit 16 is inserted in this manner, it is preferable that the slit 16 is narrowed inward when inserted into the fixed terminal insertion hole 14 and becomes easier to insert into the fixed terminal insertion hole 14 than that shown in FIG.

One of the features of the connecting member 10 shown in FIG. 5 is that the pierce terminal 13 is formed by being bent at the end of the planar piece 11 as in FIGS. 3 and 4, whereas the fixed terminal 12 is a surface. First, the planar piece 11 extends from the end of the planar piece 11 so as to be flush with the planar piece 11, and the distal end of the planar piece 11 is bent in the same direction as the pierce terminal 13. .
In other words, in the connecting member 10 of FIG. 5, at least two pierce terminals 13 are bent in an opposing state, and at least two fixed terminals 12 are similarly bent in an opposing state, and these pierce terminals 13, 13 are formed. The fixed terminals 12 and 12 are formed such that the distance between the bent portions facing each other is larger than the distance between the bent portions facing each other.
By adopting such a configuration of the connection member 10, when the flat cable 20 is deformed by bending or the like, a portion extending flush with the planar piece 11 of the fixed terminal 12 is deformed of the flat cable 20. And the flat cable 20 can be kept flat. At the same time, the stress due to the deformation of the flat cable 20 can be received mainly at the connection portion between the fixed terminal 12 and the flat cable 20.
Therefore, stress due to deformation of the flat cable 20 is prevented from being applied to the pierce terminal 13, thereby preventing deterioration of mechanical and electrical connection between the pierce terminal 13 and the conductor 26 of the flat cable 20.
Another feature resides in that a stopper 17 is provided at the distal end portion of the fixed terminal 12 to prevent it from coming off.
Thus, it is preferable to provide the anti-detachment window opening 17 at the tip of the fixed terminal 12 because the fixed terminal 12 is more difficult to be removed from the support 29 after the fixed terminal 12 is inserted into the support 29.

  Each of the connection members 10 shown in FIGS. 3 to 5 is used when the flat cable 20 and the support 29 are both on the same side as viewed from the light emitting component 22. Of course, various shapes other than these can also be applied, but they are optimal in each case depending on conditions such as the shape and size of the lead 34 of the light emitting component 22, the width of the conductor 26 of the flat cable 20, and the thickness of the support 29. What is necessary is just to select the connection member 10 of a various shape.

On the other hand, when the flat cable 20 and the support 29 are present on the opposite side as viewed from the light emitting component 22, in other words, when the flat cable 20 and the support 9 are in a state of sandwiching the light emitting component 22, for example, FIG. A connecting member 10 as shown in FIG.
In FIG. 6, the piercing terminal 13 of the connection member 10 is pierced and connected to the lower flat cable 20 side, and the fixed terminal 12 is opposite to the piercing terminal 13 with respect to the planar piece 11 of the connection member 10. It is bent upward at a substantially right angle. Therefore, although not shown in FIG. 6, the fixed terminal insertion hole 14 of the support 29 is positioned in the arrow-shaped portion of the fixed terminal 12 from above toward FIG. 6, and the tip of the fixed terminal 12 is inserted into the fixed terminal. Fit into hole 14.
In FIG. 6, a recess 18 is provided at substantially the center of the planar piece 11 of the connecting member 10.
BB sectional view and CC sectional view of the recess 18 are shown in FIGS.
As shown in FIG. 7, in the shearing portion 19, the planar piece 11 of the connecting member 10, the lead 34 of the light emitting component 22, and the flat cable 20 are partially sheared by pressing from the front side to the back side of the flat cable 20. Is formed. The sheet piece 11 is pressed and connected to the lead 34 by the shearing portion 19, and more preferably, the lead 34 directly engages the conductor 26, so that the sheet piece 11, the lead 34, and the conductor 26 are electrically and mechanically connected. The connection is secure.

FIGS. 8 and 9 show other shapes of the connecting member 10 shown in FIG. 6, both of which are used when the flat cable 20 and the support 29 are located on different sides when viewed from the light emitting component 22. is there. That is, the connecting member 10 is of a type used when the support 29 is on the fixed terminal 12 side and the flat cable 20 is on the pierce terminal 13 side.
The feature of the connecting member 10 shown in FIG. 8 is that the pierce terminal 13 extended from the end of the planar piece 11 of the connecting member 10 is immediately bent at the end of the planar piece 11, and the other fixed terminal. 12 extends from the end of the planar piece 11 so as to be flush with the planar piece 11, and its tip is bent in a direction opposite to the pierced terminal 13 with respect to the planar piece 11, in this example, substantially at a right angle. It is in the point.
Since the connecting member 10 of FIG. 8 has a configuration in which the opposing interval of the bent portions of the fixed terminals 12 and 12 is wider than the opposing interval of the bent portions of the pierce terminals 13 and 13 as in the connecting member 10 of FIG. Deterioration of the mechanical and electrical connection between the pierce terminal 13 and the conductor 26 of the flat cable 20 is prevented.

The connection member 10 shown in FIG. 9 has a most typical shape in which the fixed terminal 12 and the pierce terminal 13 are bent in different directions. Since there are four fixed terminals 12, it can be fixed to the support 29 more reliably.
Various shapes other than the connecting member 10 shown in FIGS. 6, 8, and 9 can be used. In this case, the connecting member 10 shown in FIGS. 3 to 5 is the same as described above. As described above, in accordance with conditions such as the dimensions of the leads 34 of the light emitting component 22, the conductor 26 of the flat cable 20, and the support 29, the number of the fixed terminals 12 and the pierce terminals 13, for example, the fixed terminals. What is necessary is just to consider the shape of 13 front-end | tip parts.

By the way, although the connection member 10 described above is shown only as a separate member from the light emitting component 22, in the present invention, for example, as shown in FIG. The light emitting component 22 may be integrated with the planar piece 11 so as to function as the connecting member 10. In other words, the lead 34 may be shaped like the connection member 10.
In this way, the number of parts can be reduced, and the positioning work between the lead 34 and the connecting member 10 is not necessary, so that a series of work can be performed more easily. Furthermore, since the lead 34 and the connection member 10 are integrated, the electrical connection state is improved and the lead 34 and the connection member 10 are preferable.

  In each of the above-described embodiments, as shown in FIG. 1, the fixed terminal insertion hole 14 is provided in the fixed terminal insertion hole block 15 provided on the surface of the support 29. If the thickness is sufficient to hold the fixed terminal 12 of the connecting member 10, for example, as shown in FIG. 11, the fixed terminal insertion hole block 15 is not provided, and the fixed member 12 is simply fixed. Only the terminal insertion hole 14 may be provided directly on the support 29.
