Next, assembly of the LED modules 1 each configured as described above will be described.
First, as shown in FIG. 4 (a), the connection terminal insertion recess 79 of the device holder 7 that is turned upside down so that the bottom surface is the upper side is connected upside down so that the piercing blade 63b protrudes upward. The terminal 6 is inserted into the through hole 72 so that the contact plate 61 penetrates.

  By inserting the connection terminal 6 into the connection terminal insertion recess 79, the connection terminal 6 has a mode in which the piercing blade 63b protrudes from the bottom surface of the device holder 7, as shown in FIG. As shown in c), when the upper surface is returned to the upper side, the contact plate 61 penetrating the through hole 72 projects into the device insertion recess 70 from the inside of the reaction force block 71 in plan view. .

  Then, the intermediate terminal 5 is inserted from above the device insertion recess 70 of the device holder 7 to which the connection terminal 6 is inserted. Thereby, while arrange | positioning so that the intermediate part 51b between the two V-shaped parts 51a may be on the side block 73, the terminal contact part 52 is arrange | positioned in the position which opposes the contact plate 61 in the width direction W, It can be inserted in such a manner that the width direction W position is fixed by the side longitudinal direction frame 53a.

  Thus, in the state where the connection terminal 6 and the intermediate terminal 5 are assembled to the device holder 7, the main spring 51 is sandwiched by the terminal contact portion 52 of the intermediate terminal 5 forming the sub spring 52 a and the contact plate 61. Is arranged at an out-of-plane position with respect to a virtual plane S (see FIG. 6B), that is, a position eccentric in the height direction.

  As shown in FIG. 4D, the electronic device 3 is inserted from above the device insertion recess 70 with the intermediate terminal 5 and the connection terminal 6 inserted. Specifically, as shown in FIG. 6, the resistor 40 has a contact plate 61 of the resistor connection terminal 6 a and a terminal of the resistor arrangement opening 55 a inside the resistor reaction force block 71 a in the device insertion recess 70. The LED 30 is inserted in such a manner as to be sandwiched between the contact portion 52 and the LED 30 on the inner side of the LED reaction force block 71b in the device insertion recess 70 in a plan view and the LED arrangement opening 61 of the LED connection terminal 6b. It is inserted and inserted so as to be sandwiched between the terminal contact portion 52 of 55b.

  Thus, since the spring constant k2 of the sub spring 52a of the terminal contact portion 52 is set smaller than the spring constant k1 of the main spring 51, the stopper piece of the interruption allowance H (see FIG. 7A). The terminal contact portion 52 is deformed up to the deformation amount h1 regulated by 52b (see FIG. 7B), and the main spring 51 having a large spring constant is deformed by the deformation amount h2 (FIG. 7C). Further, the remaining deformation amount h3 is set to be absorbed by the deflection of the intermediate terminal 5 (see FIG. 7D). The deformation amount h1 is set to a deformation amount at which the sub spring 52a is plastically deformed.

Note that the above-mentioned interrupt allowance H does not include dimensional tolerances, and the actual electronic device 3 and the intermediate terminal 5 include tolerances. Since the main spring 51 is deformed after the deformation of the terminal contact portion 52 is restricted by the stopper piece 52b, and the remaining deformation can be absorbed by the deflection of the intermediate terminal 5, the dimensional tolerance is ensured. The electronic device 3 can be inserted by absorbing the interruption allowance H including
Thereby, LED30 and the resistor 40 can be attached to the device holder 7 in the aspect which does not protrude from the upper surface of the device holder 7. FIG.

  In this way, the LED module 1 is assembled by sandwiching the flat cable 100 in the vertical direction between the device holder 7 with the electronic device 3, the intermediate terminal 5 and the connection terminal 6 inserted and the under holder 9 (see FIG. 5).

  Specifically, the flat cable 100 is arranged between the device holder 7 and the under holder 9 arranged above and below, and the flat cable 100 is positioned in the engagement groove 91 of the under holder 9 so that the notch 102a and the pilot hole 81 correspond to each other. (Refer to FIG. 5 (b)), the pilot pin 80 of the device holder 7 is inserted into the pilot hole 81 of the under holder 9, and the under holder 9 and the device holder 7 are fitted to each other to mount the LED module 1. assemble.

  By fitting the under holder 9 and the device holder 7, the piercing blade 63 b of the piercing portion 63 protruding downward from the bottom surface of the device holder 7 is pressed downward by the roof portion 63 a through the connection terminal insertion recess 79. The connection terminal 6 and the conductor 101 are electrically connected through the conductor 101 together with the non-conductive laminate sheet 102 of the flat cable 100.

  Since the tip of the piercing blade 63b penetrating the flat cable 100 is inserted into the avoidance recess 92, the device holder 7 and the under holder 9 are not adversely affected by the penetrating tip of the piercing blade 63b. Can be fitted.

  As described above, the electronic device 3 is sandwiched while being urged from both sides in the width direction W which is the opposite direction by the terminal contact portion 52 and the contact plate 61 in the intermediate terminal 5 and the connection terminal 6 inserted in the device holder 7. Therefore, the electronic device 3 and the flat cable 100 can be connected in a stable connection state.

  The intermediate terminal 5 includes a main spring 51 and a sub spring 52a provided in the terminal contact portion 52. The spring constant k2 of the sub spring 52a is different from the spring constant k1 of the main spring 51. , K1> k2, so that the terminal contact portion 52 is deformed first, and then the main spring 51 can be deformed.

  Thereby, for example, a connection state can be ensured corresponding to a large deformation including a dimensional tolerance. Therefore, the electronic device 3 and the flat cable 100 can be connected in a stable connection state by being sandwiched in a state of being reliably urged.

Further, the terminal contact portion 52 is provided with a stopper piece 52b that restricts deformation beyond a predetermined deformation amount, and the terminal contact portion 52 is configured to be deformable up to a predetermined deformation amount in the plastic deformation region by the stopper piece 52b. Has been.
Accordingly, the deformation amount of the sub spring 52a can be adjusted to a desired deformation amount. For example, the ratio of the deformation amount of the main spring 51 and the sub spring 52a can be set to an appropriate ratio, and the remaining deformation amount can be set. Can be absorbed by the bending of the intermediate terminal 5. Therefore, even when the tolerance due to the electronic device 3 or the creep deformation of the device holder 7 is taken into consideration, it is possible to realize the pinching in the state of being surely biased.

Further, the intermediate terminal 5 is formed in the shape of a day shape in plan view formed by three main springs 51 and a longitudinal frame 53 connecting the ends of the three main springs 51 to form a subspring 52a. By disposing the intermediate terminal 5 at a position that is biased at an out-of-plane position with respect to the virtual plane S including the pinching direction w between the terminal contact portion 52 and the contact plate 61, the deformation amount due to the sub spring 52 a and the main spring 51 is exceeded. Even when the deformation occurs, the deformation exceeding the deformation amount by the sub spring 52a or the main spring 51 can be absorbed by the bending of the intermediate terminal 5.
Therefore, the subspring 52a and the main spring 51 can be reliably functioned and can be connected in a state of being reliably urged.

  In the description of the method for attaching the LED module 1 to the flat cable 100, the flat cable 100 is penetrated and electrically connected by the piercing blade 63b. However, in order to prevent the piercing blade 63b from coming out, A portion protruding from the bottom surface of the cable 100 may be curled, or may be retained by a retaining jig.

  In addition, the electronic device 3 is inserted into the device holder 7 to which the intermediate terminal 5 and the connection terminal 6 are inserted, and is then fitted to the under holder 9 and connected to the flat cable 100. The intermediate terminal 5 and the connection terminal A configuration in which the electronic device 3 is inserted after the device holder 7 and the under holder 9 to which 6 is inserted is first fitted and connected to the flat cable 100 may be adopted.

  Further, as shown in FIG. 8, which is a perspective view of the intermediate terminal 5 ′ of another embodiment, the longitudinal frame connecting the ends of the three main springs 51 opposes the urging force of the main springs 51. You may comprise by reinforcement frame 53 'used as a reinforcement means.

With this configuration, since the locking portion 54 can be locked and fixed to the device holder 7, the longitudinal frame 53 ′ can be reliably fixed to the device holder 7 and the longitudinal frame 53 ′ locked to the device holder 7. As a reaction force, the urging force in the width direction W can be reliably applied.
Accordingly, the electronic device 3 can be securely sandwiched and connected between the contact plate 61 and the terminal contact portion 52 while being urged from both sides in the width direction W.
