The connection terminal is composed of a mounting portion that is mounted on the box, a connection end portion that is in contact with the contact portion in a mounted state, and a cable connection portion that is connected to an electric cable. By simply attaching the connection terminal to the box with the electronic parts fitted by the attachment part and connecting the cable connection part to the electric cable, the connection end and the contact of the electronic part come into contact with each other. Can be electrically connected.

  Therefore, for example, compared to the case where electronic components that are increasingly miniaturized are connected by soldering, the number of man-hours for connection can be reduced, the equipment can be simplified, and quality control is facilitated. can do.

  As an aspect of the present invention, the connection end portion is configured to be biased with respect to the contact portion, so that the electronic component and the connection terminal can be reliably and easily electrically connected. The assemblability of the structure can be improved.

  Further, as an aspect of the present invention, the electronic component is constituted by a light source device, and a lens is provided inside the box in the irradiation direction of the light source device, so that the connection structure is attached to an electric cable. A light source module that can irradiate light through a lens can be obtained.

  Even with light source devices that are increasingly miniaturized, a lens-equipped light source module can be easily obtained because a lens is mounted inside the box. Further, the number of assembling steps can be reduced as compared with a light source module in which a lens is separately installed.

  As an aspect of the present invention, the electric cable includes a plurality of flat conductors arranged at predetermined intervals in the width direction, and a covering portion that integrally covers the plurality of flat conductors in a flat plate shape.

  That is, the connection terminal can be connected without bending the through-connection portion that penetrates the flat cable. Therefore, in the step for connecting the connection terminal to the flat cable, the step of bending the through connection portion can be eliminated. Moreover, the reliability of the connection of the connection terminal to the flat cable can be improved.

  In addition, since the surface of the flat conductor to be connected to any one of the through connection portions and the surface substantially parallel to the through direction are in contact with the inner surface of the insertion port, a contact area can be secured. By this contact, it is possible to reliably prevent the penetration connecting portion from coming out.

  Further, as an aspect of the present invention, in the insertion port in the insertion state of the through-connection portion, a predetermined gap is formed on the side opposite to the contact surface side with the inner side surface of the through-connection portion, and in the length direction.

Even in the case of inserting in a state shifted in the direction, the predetermined gap can absorb the shift and can be easily inserted into the insertion port.

  In addition, for example, when a plate is installed on the side through which the through-connection portion of the flat cable penetrates and the through-connection portion penetrates the flat cable, the flat cable on the side where the through-connection portion and the inner surface of the insertion port contact is sheared. The flat cable is stretched and broken due to a predetermined gap on the opposite side. Then, the stretched and broken end face can be surely brought into contact with the through connection portion, and the connection terminal and the flat cable can be reliably electrically connected via the through connection portion.

  In addition, by staggering at a predetermined interval in the width direction, the opposite positions of at least two through-connection portions, that is, the side surfaces on different sides of the two adjacent through-connection portions, and the insertion port can be reliably brought into contact with each other. This prevents the inserted piece from coming out.

A connection part can be inserted in the insertion port of a plate, and a connection terminal can be connected to a flat cable.

  In addition, since the plate box is configured to hold the plate so as to be movable in a direction perpendicular to the penetrating direction, when the component box and the plate box are fitted, the planar positions of the through connection portion and the insertion port are Even if it is shifted, the through-connecting portion can be guided and inserted into the insertion port easily and reliably by moving the plate.

  Further, as another aspect of the present invention, the through-connection portion penetrating the flat conductor can be separated from the flat conductor without using another member by bending the through-connection portion that has penetrated through the flat conductor. It can be prevented from coming out. Therefore, the flat conductor and the connection terminal can be reliably connected.

The LED module 1 is a module for attaching the LED chip 30 to the flat cable 100. The flat cable 100 includes two strip-like conductors 101 arranged in parallel at a predetermined interval in the width direction and a non-conductive laminate sheet 102 that sandwiches the conductors 101 from the front and back sides and integrally surrounds them. is doing. Although only a part of the flat cable 100 is shown in the figure, the flat cable 100 is formed with a required length and is routed at a predetermined location inside the vehicle or the like.
The conductor 101 formed with a thickness of about 0.01 to 0.5 mm and a width of about 0.1 to 3 mm is used.

  The LED module 1 includes a connection terminal 10, a case 20 with a lens, and an LED chip 30. As shown in FIG. 5, the LED chip 30 serving as a light emitting source includes a light emitting portion 31 having a circular shape in plan view on the upper surface, and each of both side surfaces of the flat cable 100 in the width direction (hereinafter simply referred to as “width direction”). Is provided with an L-shaped contact terminal 32 continuous from the bottom, and is formed in a substantially rectangular parallelepiped of about 1 to 2 mm square having a low height with respect to the width and depth.

The lens-equipped case 20 is slightly larger than the LED chip 30 and has a substantially rectangular parallelepiped shape with a chamfered planar viewing angle portion. And as shown in FIG. 4, the insertion piece of the connection terminal 10 mentioned later is provided in the both sides | surfaces of the LED mounting part 21 which is the space where the lower surface which mounts LED chip 30 was opened inside, and the LED mounting part 21 in the width direction 11 in the longitudinal direction of the flat cable 100 on both side surfaces in the width direction of the lens-equipped case 20 and the lens portion 23 provided above the center of the LED mounting portion 21 in plan view. In FIG. 5, a locking groove 24 having a height of about 2/3 from the upper end of the lens-equipped case 20 is provided.
The LED mounting portion 21 and the insertion portion 22 are formed in an integrated space.

  FIG. 4 is an enlarged cross-sectional view taken along the line XX (see FIGS. 2 and 3) that is a plane perpendicular to the length direction of the flat cable 100 and crosses the lens portion 23 as a center.

  FIG. 6A shows a cross-sectional view of the connection terminal 10 in the vicinity of the center in the length direction of the connection terminal 10 in a state of being arranged to face each other, FIG. 6B shows a right side view, and a plan view. As shown in FIG. 6 (c), a plate-like pedestal portion 12 having a length approximately three times as long as the lens-equipped case 20, and an upper portion from one edge in the width direction at the substantially center in the length direction of the pedestal portion 12. And an insertion claw 13 that protrudes downward from both widthwise edges of the pedestal portion 12.

  The insertion claws 13 are formed in a trapezoidal shape with a narrow side at the bottom, and a plurality of insertion claws 13 are arranged at predetermined intervals in the length direction, and further, the insertion claws 13 on both sides in the width direction are arranged alternately. (See FIG. 6B).

  In addition, a contact 15 formed by cutting into a substantially U shape with the insertion piece 11 side up and bending upward is provided at the approximate center of the pedestal portion 12. Further, a stopper 14 is provided near the center of the upper portion of the insertion piece 11 and is formed by cutting it into a substantially U shape and bending it outward in the width direction with the upper portion as a fulcrum.

  The stopper 14 is formed with a width that is slightly narrower than the opening width of the locking groove 24, and the stopper 14 extends outward in the locking groove 24 in a state where the insertion piece 11 is inserted into the insertion portion 22. In this configuration, the tip 14a of the stopper 14 is locked to the locking corner 24a.

In addition, although the connection terminal 10 has appropriate elasticity and conductivity and is formed of a steel thin plate member having a plate thickness of about 0.1 to 0.5 mm, the terminal is a member having excellent conductivity. It is preferable to form, for example, not only the copper member but also a copper alloy member.
Specifically, the steel thin plate member is cut into an appropriate size, and the above-described configuration is formed by bending or bending.

  Therefore, it is possible to obtain the stopper 14 and the contact 15 having the appropriate elasticity while maintaining the shape. Furthermore, the contact 15, the pedestal portion 12, and the insertion claw 13 have conductivity and are integrally formed electrically.

  As described above, the LED module 1 can be configured by combining the connection terminal 10, the lens-equipped case 20, and the LED chip 30 having the above-described configuration.

  Specifically, as shown in FIG. 7 for explaining the assembly method of the LED module 1 by a perspective view on the back side, the case with lens 20 is turned upside down so that the open surface of the LED mounting portion 21 is on the upper side, The LED chip 30 that is turned upside down so that the bottom side is the upper side is mounted on the LED mounting portion 21 (see FIG. 7A). At this time, since the LED mounting portion 21 is formed in accordance with the mounting direction of the LED chip 30, the LED chip 30 is mounted so that the contact terminals 32 are in the width direction.

  And the insertion piece 11 is inserted in the insertion part 22 which exists in the outer side of both the contact terminals 32 of LED chip 30 (refer FIG.7 (b)). At this time, it arrange | positions so that the base part 12 of the two connection terminals 10 may oppose. When the stopper 14 that has been closed against the biasing force reaches the locking groove 24 when inserted into the insertion portion 22, the stopper 14 spreads outward in the width direction due to the biasing force, and the tip 14a of the stopper 14 is locked at the locking corner 24a. The insertion piece 11 is prevented from coming out of the insertion portion 22 (see FIG. 4).

When the insertion piece 11 is inserted up to this state, the contact 15 is pressed against and brought into contact with the contact terminal 32 against the urging force (see FIG. 4).
In addition, by pushing the stopper 14 inward in the width direction against the urging force, the locking with the locking corner portion 24 a is released, and the insertion piece 11 can be extracted from the insertion portion 22.

  Thus, by inserting the insertion piece 11 and attaching the connection terminal 10 to the insertion part 22 of the lens-equipped case 20 in which the LED chip 30 is attached to the LED attachment part 21 having the lens part 23 above, The LED chip 30 and the connection terminal 10 can be reliably and easily electrically connected by the contact 15 and the contact terminal 32 which are in contact with each other against the urging force, and the lens unit 23 is arranged in the irradiation direction of the light emitting unit 31. Can be arranged.

  Further, since the contact 15 is in contact with the contact terminal 32 against the urging force, a force in the direction of coming out of the lens-equipped case 20 is applied to the connection terminal 10 by the urging force of the contact 15. Since the stop portion 24 a is locked, the insertion piece 11 does not come out of the insertion portion 22.

  Further, the connection terminal 10 is more stably attached to the lens-equipped case 20 and the LED chip 30 by the urging force in the direction in which the contact 15 is pulled out and the elastic force of the stopper 14 that is locked to the locking corner portion 24a. Can do.

  As shown in FIGS. 8 and 9, the LED module 1 assembled in this way penetrates a predetermined conductor 101 to be connected together with the non-conductive laminate sheet 102 with the insertion claws 13 provided in each pedestal portion 12. Then, the insertion claw 13 that penetrates is bent toward the center in the width direction of the conductor 101 and attached to the flat cable 100.

  FIG. 8 is an explanatory diagram for explaining the mounting of the LED module 1 to the flat cable 100 with a perspective view from the bottom surface side, and FIG. 9 is a perspective view from the bottom surface side of the LED module 1 attached to the flat cable 100.

  According to the configuration, the assembling method, and the connecting method, the LED module 1 of the present invention mounts the LED chip 30 serving as a light source on the LED mounting portion 21, and inserts the insertion pieces 11 of both connection terminals 10 into the insertion portion 22. In the inserted state, the LED chip 30 can be operably mounted simply by being attached to the flat cable 100 by the insertion claw 13.

  Therefore, for example, compared with the case where the LED chip 30 that is increasingly miniaturized is connected by soldering, it is possible to reduce the man-hours for connection, simplify the equipment, and facilitate quality control. can do.

  In addition, since the two connection terminals 10 are formed in the same shape, the types of components constituting the LED module 1 can be reduced compared to the case where connection terminals having different shapes are required, and the ease of assembly of the LED module 1 can be reduced. While being able to improve, the component cost of this LED module 1 can be reduced.

  In addition, a plurality of insertion claws 13 arranged alternately on both sides in the width direction of the pedestal portion 12 are provided, and the insertion claws 13 are centered from both sides in a state of passing through the conductor 101 together with the non-conductive laminate sheet 102. Since the pedestal portion 12 and the insertion claw 13 hold the conductor 101, the connection terminal 10 can be securely and stably attached to the flat cable 100.

  In the present embodiment, the LED chip 30 is mounted on the LED mounting portion 21 and the contact 15 is in close contact with the flat cable 100 as shown in FIG. 4 with the insertion piece 11 mounted on the insertion portion 22. The LED chip is biased to a flat state and contacts the contact terminal 32, but the LED chip is lifted from the bottom surface of the LED mounting part 21 so that a gap is formed below the LED chip 30 mounted on the LED mounting part 21. 30 may be fixed, and the contact 15 may be lifted from the flat cable 100 and contact the contact terminal 32 in such a manner that it does not adhere.

  In this embodiment, the LED module 1 is assembled by attaching the connection terminal 10 to the lens-equipped case 20 to which the LED chip 30 is attached. Conversely, the LED chip 30 such as a hook is attached to the insertion piece 11 of the connection terminal 10. A configuration may be provided in which mounting means for mounting is provided, the LED chip 30 is mounted on the mounting means, and then the lens case 20 is mounted to assemble the LED module 1. Thereby, the LED module 1 by the assembly method according to an assembly condition can be used selectively, and the satisfaction of the user who uses the LED module 1 can be improved.

  In the present embodiment, the lens-equipped case 20 having the lens portion 23 near the center of the upper surface is used. For example, a case without a lens is used according to the purpose of use of the LED module 1 after being mounted. Also good.

  Further, as the electric cable for connecting the LED module 1, two strip-shaped conductors 101 arranged in parallel at a predetermined interval in the width direction, and the non-conductive that sandwiches the conductors 101 from the front and back and integrally surrounds them. The flat cable 100 made of the conductive laminate sheet 102 is used, but a ribbon electric wire in which covered round stranded wires are arranged in the width direction and integrated may be used.

Thereby, the LED module 1 can be connected to the electric cable according to the desired location using the LED module 1, the application location of the LED module 1 increases, and a user's satisfaction can be improved.

  More specifically, as shown in FIG. 12, first, the upper case 40 is turned upside down and the LED chip 30 turned upside down is mounted on the LED mounting portion 21. Then, the insertion piece 11 is inserted into the insertion portion 22 existing outside both the contact terminals 32 of the LED chip 30, and the LED chip 30 and the connection terminal 10 a are attached to the upper case 40.

At this time, the insertion claw 13 is configured to protrude downward from the bottom surface of the upper case 40.
FIG. 12 is an explanatory diagram for explaining a method of mounting the connection terminal 10 a and the LED chip 30 to the upper case 40.

  Next, the backup plate 60 is mounted in the mounting recess 52 of the plate case 50. At this time, the backup plate 60 is mounted in the approximate center of the mounting recess 52 formed slightly larger than the outer shape of the backup plate 60 in plan view. .

  Subsequently, the flat cable 100 is disposed between the upper case 40 in which the connection terminal 10 a and the LED chip 30 are mounted and the plate case 50 in which the backup plate 60 is set in the mounting recess 52. With the flat cable 100 sandwiched from above and below, the locking hook 51 is locked to the locked portion 43, and the upper case 40 and the plate case 50 are fitted.

At this time, the insertion claw 13 protruding downward from the bottom surface side of the upper case 40 passes through the flat cable 100, and the inserted insertion claw 13 is inserted into the insertion port 61 as shown in FIG. 14. In this state, the insertion claw 13 can be electrically connected to the conductor 101 as will be described later.
FIG. 14 is an explanatory diagram showing a perspective view from the bottom side for explaining an assembly method and a connection method of the LED module 3.

The electrical connection between the insertion claw 13 and the conductor 101 will be described in detail. The insertion claw 13 penetrates the conductor 101 together with the non-conductive laminate sheet 102 in a state where the backup plate 60 is disposed on the bottom surface side of the flat cable 100. At this time, as shown in FIG. 15, the conductor 101 on the side where the insertion claw 13 and the inner side surface 61 b of the insertion opening 61 come into contact is sheared and broken by the insertion claw 13.
On the other side where the predetermined gap 61a is set, the conductor 101 is stretched and broken by the predetermined gap 61a with the upper end of the inner side surface 61c as a fulcrum.

15 is a view cut along a plane perpendicular to the length direction of the flat cable 100, and is an enlarged cross-sectional view illustrating penetration of the insertion claw 13 through the flat cable 100. FIG.
In this way, the stretched and broken fracture end surface 101a can reliably contact the side surface of the insertion claw 13, and the connection terminal 10a and the conductor 101 can be reliably connected via the insertion claw 13.

  Thus, the LED module 3 can obtain the same effects as those obtained by the LED module 1 described in the first embodiment by the configuration, the assembling method, and the connecting method.

  Furthermore, by inserting the upper case 40 with the connection terminal 10a attached thereto and the plate case 50 with the backup plate 60 attached to the attachment recess 52, the insertion claw 13 penetrates to the bottom surface side of the flat cable 100, The insertion claw 13 can be inserted into the insertion port 61.

At this time, the side surfaces of the two insertion claws 13 inserted into the insertion port 61 are in reliable contact with the side surfaces of the insertion port 61.
The insertion claw 13 is formed in a thin plate shape having side surfaces substantially parallel to the length direction and the penetration direction of the conductor 101, that is, the length direction and the penetration direction of the flat cable 100, and a plurality of insertion claws 13 are arranged in the length direction. The contact area can be ensured by arranging and making contact with either one surface of the insertion claw 13 and the inner surface 61b of the insertion port 61.

  In the present embodiment, an example in which the upper case 40 and the plate case 50 are fitted is shown, but the insertion claw 13 and the insertion port 61 are in contact with each other without the upper case 40 and the plate case 50. What is necessary is just to insert this insertion nail | claw 13 in the insertion port 61. FIG. However, as in this embodiment, the upper case 40 and the plate case 50 are provided and fitted, so that the insertion claw 13 and the insertion port 61 are stabilized due to the fitting effect between the upper case 40 and the plate case 50. Can be contacted.

  Further, as shown in FIG. 16 (a), a plurality of insertion openings 61 arranged in the length direction are arranged in a staggered manner at a predetermined interval w in the width direction, so that the two insertion claws 13 are opposed to each other, that is, adjacent to each other. The side surfaces on the different sides of the two insertion claws 13 and the inner side surface of the insertion port 61 come into reliable contact.

  Specifically, by inserting the insertion claw 13 penetrating the flat cable 100 into the insertion port 61, the left side surface of the upper insertion port 61 contacts the side surface of the insertion claw 13, as shown in FIG. The right side surface of the lower insertion slot 61 contacts the side surface.

  In this way, since the opposing side surfaces of the two insertion claws 13 come into contact with the inner side surface 61 b of the insertion port 61, the inserted insertion claw 13 comes out of the insertion port 61 due to frictional resistance caused by contact between the surfaces. Can be prevented.

  That is, the connection terminal 10 a can be connected to the conductor 101 without bending the insertion claw 13 penetrating the conductor 101. Therefore, the process of bending the insertion claw 13 in the process for connecting the connection terminal 10a to the conductor 101 can be eliminated.

  Further, as shown in FIG. 16 (a), since the insertion port 61 is formed in a shape having a predetermined gap 61a on the opposite side of the contact side of the insertion claw 13 in the insertion state of the insertion claw 13, for example, Even when the insertion position of the insertion claw 13 with respect to the insertion port 61 is shifted when the upper case 40 and the plate case 50 are fitted, that is, even when an error occurs in the insertion position, the predetermined gap 61a is The error can be absorbed.

  Further, since the plate case 50 is configured to hold the backup plate 60 so as to be movable in a direction perpendicular to the penetrating direction, when the upper case 40 and the plate case 50 are fitted, the insertion claw 13 and the insertion port 61 Even when the planar position is shifted, the back-up plate 60 moves in the mounting recess 52, so that the insertion claw 13 can be guided and inserted into the insertion port 61 easily and reliably. Therefore, the connection terminal 10a can be reliably attached to the flat cable 100.

  In the present embodiment, two insertion claws 13 aligned in a straight line in the length direction are inserted into two insertion openings 61 that are alternately shifted to the left and right by a predetermined amount w, and different insertion claws are inserted. 13 is in contact with the insertion port 61 at a position facing the portion 13, and the frictional resistance at the contact portion prevents the insertion claw 13 from coming out of the insertion port 61. FIG. As shown in FIG. 16 (b), it may be configured by one communication insertion port 62 that communicates in a planar view wave type so that the side surfaces in contact with the insertion claws 13 are alternately left and right.

  Also, as shown in FIG. 17A, the insertion ports 61 are arranged in a straight line in the length direction, and the contact with the inner side surface 61b of the insertion port 61 arranged in a straight line is alternately left and right. The insertion claws 13 may be alternately shifted by a predetermined amount w2 in the width direction, that is, staggered. As a result, the side surfaces of the insertion claws 13 provided in two in the length direction alternately contact the left and right inner side surfaces 61b of the insertion port 61, and the insertion claws 13 come out of the insertion port 61 due to the contact between the surfaces. This can be prevented.

  Further, as shown in FIG. 17 (b), the insertion ports 61 are arranged in a staggered manner even when formed with a continuous insertion port 62 formed in an I-shaped slit shape in plan view that is about twice the thickness of the insertion claw 13 in the width direction. The same effect as the case can be obtained.

  Furthermore, as shown in FIG. 18A, the insertion claw 13 and the insertion port 61 may be alternately shifted by a predetermined amount w3 and w4 in the width direction. Further, as shown in FIG. 18 (b), the insertion claws 13 are alternately staggered by a predetermined amount w3 in the width direction, and the insertion claws 13 arranged in a staggered manner are inserted to face different insertion claws 13. It may be configured by a single communication insertion port 62 that is in contact with the planar viewing wave.

  Further, the backup plate 60 provided with the two insertion openings 61 in the length direction is mounted in each of the two mounting recesses 52. However, the backup plate 60 provided with the four insertion openings 61 may be used. .
