  1 to 2 show an embodiment of a circuit body holding case and a circuit body module having the circuit body holding case according to the present invention.

  As shown in FIG. 1, the circuit body holding case 2 is made of an insulating synthetic resin as a material and has a substantially strip-shaped long circuit body housing portion 71 and a plurality of circuit body housing portions 71 (in this example). It is composed of a terminal accommodating portion 72 that is integrally provided via three (three) parallel (parallel) flexible string-like connecting portions 73.

  The circuit body accommodating portion 71 is configured by connecting a plurality of accommodating portions 13 with connecting portions 14 and 15. In each accommodating portion 13, a flexible flat circuit body (circuit body) 4 is accommodated in a state of being bent (projected) in a wave shape, and from the bottom opening 6 of the accommodating portion 13, the protruding portion 7 of the flat circuit body 4 is accommodated. The tip portion protrudes to the outside, and the temperature sensor 5 (FIG. 5) is connected and fixed to the inner surface of the tip portion. A flat circuit body 4 is arranged in a straight (flat) state at the connecting portions 14 and 15 between the accommodating portions 13.

  In FIG. 1, a rubber cover 3 is attached to the case 2 from above the flat circuit body 4. The case 2, the flat circuit body 4, and the cover 3 constitute a circuit body module 1. The circuit module (temperature detection module) 1 of this example is used to detect the temperature of each battery 9 (FIG. 4) of a battery 8 (FIG. 3) such as an electric vehicle. The cover 3 can be eliminated.

  As shown also in FIG. 2, the terminal accommodating part 72 of case 2 is comprised by the accommodating part main body 74, the cover part 75, and the thin hinge part 77 of the one side wall 76 which connects these 74 and 75 so that opening and closing is possible. . The accommodating portion main body 74 and the lid portion 75 have a concave accommodating space 78 and are positioned by the engagement of the pin-shaped protrusion 79 and the hole 80, and the frame piece 82 and the protrusion 83 of the other side wall 81 mutually Locked.

  A terminal portion (not shown) of the flat circuit body 4 is routed in the housing portion main body 74 along the string-like connecting portion 73 from the circuit body housing portion 71. Two terminals 84 made of conductive metal are accommodated in the accommodating portion main body 74, and the printed circuit of the terminal portion of the flat circuit body 4 (FIG. 1) is connected to the distal end portion 84a of each terminal 84.

  As the connection form between the terminal 84 and the terminal portion, pressure welding, piercing (piercing the sharp terminal tip portion 84a and bending it) or the like is preferable. An insulating coated wire as a lead wire 85 is connected to the base end portion 84b of the terminal 84 by crimping or pressure contact. The lead wire 85 is led out from the tip of the terminal accommodating portion 72 to the outside. A partition plate 86 is erected on the bottom wall of the housing main body 74 between the terminals 84.

  On each base side of the string-like connecting portion 73 (the distal end 73a side and the proximal end 73b side) of the terminal accommodating portion 72, flat wall portions 87 and 88 are formed to extend on the accommodating portion main body 74 and the lid portion 75, and accommodated. A pin-shaped protrusion 79 is erected on the flat inner wall surface 87 of the main part 74, and a hole 80 is provided in the flat wall part 88 of the lid part 75. The pin-shaped protrusion 79 penetrates the hole (not shown) of the insulating sheet of the terminal part of the flat circuit body 4 and positions the terminal part. By closing the lid portion 75, the terminal portion is sandwiched and held between the inner surfaces of both flat wall portions 87 and 88.

  Similarly, a flat wall portion 89 is formed on the base side of the string-like connecting portion 73 of the circuit body housing portion 71, and a flat lid wall 91 is formed on one side wall 90 of the circuit body housing portion 71 with respect to the wall portion 89. Is provided so as to be openable and closable by the hinge portion 91a, and the flat circuit body 4 is sandwiched and held between the inner surfaces of the flat wall portions 89 and 91 by closing the lid wall 91. In FIG. 2, reference numerals 98 a and 98 b indicate locking means (protrusions and recesses) of the lid wall 91.

  2, the tip 87a of the flat wall portion 87 of the terminal accommodating portion 72 and the tip 89a of the flat wall portion 89 of the circuit body accommodating portion 71 are inclined in the same direction, and these inclined surfaces 87a and 89a are They are facing each other. A distal end 73a and a base end 73b of a string-like connecting portion 73 are integrally molded with the respective inclined surfaces 87a and 89a at the distal end, and then resin-molded. The length of each connection part 73 is the same. A parallelogram space 97 is formed between the parallel connecting portions 73. The inclined angle of each inclined surface 87a, 89a is 45 °. The slanted surfaces 87a and 89a allow the string-like connecting portion 73 to be smoothly bent.

That is, in FIG. 2, when the terminal accommodating portion 72 is bent (crossed) toward the front and downward as indicated by the arrow A with respect to the circuit body accommodating portion 71, the upper connecting portion 73 ₁ , the intermediate connecting portion, bending in the order of the connecting portion 73 ₃ of the side is carried out without difficulty by a small force (stress). Connecting portion 73 ₁ of the upper bent forward, the connecting portion 73 ₃ of the lower side of the front bent in the opposite side (depth side). If the arrow A terminal accommodating portion 72 is bent in the opposite direction (upward in FIG. 2) requires a large force to the bending is pulled strongly connecting portion 73 ₃ of the lower side.

  A locking frame portion (locking means) 93 projects from the side surface of the flat wall portion 89 on the other side wall 92 side of the circuit body housing portion 71, and the lid of the terminal housing portion 72 as shown in FIG. A claw portion (locking means) 95 inserted into and engaged with the frame portion 93 and a guide plate 96 are erected on the outer surface of the base wall of the top wall 94 of the portion 75.

  The flat circuit body 4 (FIG. 1) is accommodated in the case 2 from the state of FIG. 2, the lid portions 75 and 91 are closed, and the terminal accommodating portion 72 is moved in the 90 ° direction by the string-like connecting portion 73 as shown in FIG. By bending and engaging the claw portion 95 and the guide plate 5 with the frame portion 93, the position of the terminal housing portion 72 is regulated in a state of intersecting substantially 90 °, and the lead wire 85 is connected to the circuit body housing portion 71. On the other hand, it is derived in the direction of approximately 90 °. The reason why the angle is approximately 90 ° is that a slight shift occurs in the direction due to the backlash between the claw portion 95 and the frame portion 93. Since the lid portion 75 is locked to the frame portion 93 of the circuit body housing portion 71, the lid portion 75 is prevented from being opened unexpectedly.

  In the bent state of FIG. 1, the flat circuit body 4 is smoothly curved with a relatively large radius in the 90 ° direction along the bent inner surface of the string-like connecting portion 73, and the flat circuit body 4 is bent and The accompanying damage is prevented, and the connecting portion 73 is positioned outside the flat circuit body 4 to safely protect the flat circuit body 4 from interference with the outside. Further, since the circuit body housing portion 71 and the terminal housing portion 72 are flexibly coupled by the plurality of string-like coupling portions 73, the terminal housing portion 72 is crossed with respect to the circuit body housing portion 71. The bending (arrangement) operation can be easily and reliably performed with a small force.

  Further, since the connecting portion 73 has a string shape, the force to be restored in the bent state of FIG. 1 is small, and even when the claw portion 95 and the frame portion 93 are engaged with each other, even if the hand is released, The bending direction is maintained at approximately 90 °, and the wiring work of the lead wire 85 to a counterpart device (not shown) such as a temperature detection device is facilitated.

  For example, when the circuit body accommodating portion 71 and the terminal accommodating portion 72 are connected by a single thin plate connecting portion (not shown), since the restoring force of the connecting portion is large, the bending workability is poor and the terminal accommodating The bending direction of the portion 72 is not maintained at 90 °, but is largely rotated and shifted by the elastic force. Further, if there are no inclined surfaces 87a and 89a following the distal end and the base end of the connecting portion, the connecting portion is more difficult to bend. If a small restoring force similar to that of the string-like connecting portion 73 is to be obtained, the thin plate-like connecting portion must be made thinner, and the thin plate-like connecting portion is likely to be damaged due to repeated bending and aging. turn into.

  The string-like connecting portions 73 may be two or four instead of three. When the connecting portion 73 is one, the terminal accommodating portion 72 is twisted or bent with respect to the circuit body accommodating portion 71 in the unfolded state of FIG. And the terminal part of the circuit body 4 is not easily connected to the terminal 84 (pressure contact or the like) and is weak in strength, and the connecting part 73 is easily damaged by repeated bending.
