It is going to be inserted into the one-sided insertion hole 111. However, since the distance L1 between the first side surfaces is longer than the length La of the insertion hole 112 for the protruding projection piece, the tip end surface 441 of the protruding portion 44 provided on the central insertion projection piece 41 has the top surface 101 of the printed circuit board 100. However, the three insertion protrusions 40 cannot be inserted into the insertion holes 110. As a result, the connection of the board terminal 2 with the printed board 100 can be prohibited.

As described above, in the connection structure 1 that connects the printed circuit board 100 having the insertion hole 110 and the board terminal 2 having the insertion protrusion 4 to be inserted into the insertion hole 110, the board terminal 2 is connected to the printed circuit board 100. The orientation direction F with respect to the terminal body 3 and the insertion protrusion 4 protruding in the insertion direction H that is inserted into the insertion hole 110 with respect to the terminal body 3. The three insertion protrusions 40 symmetrically arranged with respect to the predetermined axis Z, and the overhanging portion 44 provided on the central insertion protrusion 41 of the three insertion protrusions 40, The insertion hole 110 provided in the printed circuit board 100 includes a projection piece insertion hole 111 into which the insertion projection piece 40 is inserted, and an extension projection piece insertion hole into which the insertion projection piece 40 having the overhanging portion 44 is inserted. 112, the projecting portion 44 projects in the arrangement direction Wa intersecting the inserting direction H, and the inserting projecting portion 4 has an asymmetrical shape with respect to the predetermined axis Z. It is possible to prevent the substrate terminal 2 and the printed circuit board 100 from being connected to each other in the state where the orientation direction F of the is oriented in the opposite direction.

More specifically, the protrusions 44 provided on the central insertion protrusion 41 of the three insertion protrusions 40 and projecting in the arrangement direction Wa intersecting the insertion direction H cause the insertion protrusion 4 to move to the predetermined axis Z. Although it has an asymmetrical shape with respect to the printed circuit board 100 and the board terminal 2, the three insertion protrusions 40 of the board terminal 2 with the terminal body 3 oriented in the forward direction are inserted into the insertion holes 110 (111, 112). Can be connected.

On the other hand, when the terminal body 3 is oriented in the opposite direction with respect to the printed circuit board 100, the first outer insertion protruding piece 42 of the insertion protruding portion 4 which is asymmetrical with respect to the predetermined axis Z is for the protruding protruding piece. Although it is inserted into the insertion hole 112, the overhanging portion 44 cannot be inserted into the projecting piece insertion hole 111, and the overhanging portion 44 contacts the upper surface 101 of the printed circuit board 100 to reach the insertion hole 110 of the insertion projecting piece 40. Can be prohibited, and the connection between the printed circuit board 100 and the board terminal 2 can be prohibited.

Further, in the printed circuit board 100, the projecting piece insertion hole 111 and the projecting projecting piece insertion hole 112 are arranged in the arrangement direction Wb, and the three insertion projecting pieces 40 of the board terminal 2 made of a plate material are provided. The protrusion 44 is provided along the arrangement direction Wa, and the protrusion 44 is provided on the central insertion protrusion 41 of the pair of adjacent insertion protrusions 40 of the insertion protrusion 4 and protrudes toward the second outer insertion protrusion 43. Therefore, the overhanging portion 44 does not become bulky in the thickness direction, and the connection in the opposite direction can be prevented.

Furthermore, it is easy to secure a space for arranging the overhanging portion 44, and even if the overhanging portion 44 is provided, it is possible to prevent the board terminals 2 from increasing in size in the arrangement direction Wa. Further, since the board terminal 2 is formed by cutting out from the plate material, the loss ratio of the plate material can be reduced and the yield can be improved by disposing the overhanging portion 44 between the insertion projecting pieces 40.

Further, the overhanging portion 44 is provided on the central insertion projecting piece 41, and overhangs toward the second outer inserting projecting piece 43, and the outer surface 423 of the base portion 422 of the first outer inserting projecting piece 42 and the projecting portion 44. The distance between the overhanging side surface 442 and the first side surface distance L1, and the distance between the outer surface 433 of the base portion 432 of the second outer insertion protruding piece 43 and the side surface 413 of the central insertion protruding piece 41 between the second side surfaces. Since the distance La is set to L2 and the length La in the arrangement direction Wb in the projecting protrusion insertion hole 112 is formed to be longer than the second side surface distance L2 and shorter than the first side surface distance L1, the overhanging portion 44 is formed. Insert the provided central insertion protrusion 41 with the second outer insertion protrusion 43 into the overhanging protrusion insertion hole 112, and insert the first outer insertion protrusion 42 into the protrusion insertion hole 111. The printed circuit board 100 and the directional board terminal 2 can be connected.

On the contrary, since the length La in the arrangement direction Wb of the overhanging projection insertion hole 112 is shorter than the first side surface distance L1, the central insertion projection 41 provided with the overhanging portion 44 and the first outer insertion projection 41 are provided. The piece 42 cannot be inserted into the projecting projection insertion hole 112, and the projection 44 or the first outer insertion projecting piece 42 abuts the upper surface 101 of the printed circuit board 100. 2 can be reliably prevented from connecting with the printed circuit board 100.

Further, since the outer side surfaces 423 and 433 of the outer insertion protruding pieces 42 and 43 provided on both outer sides with respect to the predetermined axis Z are mirror-symmetrical to each other, the insertion protruding piece 40 can be inserted into the insertion hole 110. At this time, or in the inserted state, the stability of the board terminals 2 in the arrangement direction Wa in the connected state can be improved as compared with the case where the outer surfaces 423, 433 of the outer insertion protruding pieces 42, 43 are not mirror image symmetrical.

Further, the outer insertion protrusions 42 and 43, which are arranged on both outer sides with respect to the predetermined axis Z, and which are composed of the front end portions 421 and 431 and the base portions 422 and 432, are retainer protruding outside the base portions 422 and 432. Since the portion 45 is provided on the tip portions 421 and 431 and the outer side surface of the retaining portion 45 is inclined outward from the tips 426 and 436 toward the base portions 422 and 432, the outer insertion projecting pieces 42 and 43 are inserted. In the state of being inserted into the hole 110, the retaining portions 45 of the outer insertion protruding pieces 42 and 43 penetrating the printed circuit board 100 are locked to the peripheral edge of the insertion hole 110, and the outer insertion protruding pieces 42 and 43 are inserted into the insertion hole 110. It is possible to regulate the careless removal from the. That is, it is possible to prevent the board terminal 2 from being accidentally detached from the printed board 100.

Further, since the tip surfaces 416, 426, 436 of the three insertion projection pieces 41, 42, 43 and the tip surface 441 of the overhanging portion 44 are formed flush with each other, the insertion of the three insertion projection pieces 40 is performed. At the timing of insertion into the hole 110, the overhanging portion 44 is brought into contact with the upper surface 101 of the printed circuit board 100 to prohibit reverse connection, and the forward board terminal 2 is reliably connected to the printed circuit board 100. be able to.

Further, the inner side surfaces 424, 434 on the inner side in the arrangement direction Wa of the outer insertion protruding pieces 42, 43 are inclined outward from the base end toward the tip end in the arrangement direction Wa, and therefore, the outer insertion protruding pieces 42, 43. It is possible to secure a sufficient space between the insertion projection piece 40 and the insertion projection piece 40 adjacent to the inner side surfaces 424 and 434.

As a result, even when the outer insertion protrusions 42, 43 are tilted toward the inner side surfaces 424, 434 in the state where the outer insertion protrusions 42, 43 are inserted into the insertion hole 110 of the printed circuit board 100, the outer insertion protrusions 42, 43 are inclined. It is possible to prevent the pieces 42, 43 and the insertion projecting piece 40 adjacent to the inner side surfaces 424, 434 thereof from coming into contact with each other.

Further, in the connected state, the lengths of the projecting piece insertion holes 111 and the projecting projecting piece insertion holes 112 located at the bases of the three inserting projecting pieces 40 in the disposition direction Wb are the first outer inserting projecting piece. Since the distance between the outer surface 423 of the base portion 422 of 42 and the outer surface 433 of the base portion 432 of the second outer insertion protruding piece 43 is approximately the same, the three insertion protruding pieces 40 are inserted into the insertion holes 110 (111, 112). The board terminal 2 inserted in () can be reliably connected to the printed board 100 without shifting in the arrangement direction Wb.

Further, the central insertion protruding piece 41 is inserted into the overhanging protruding piece insertion hole 112 together with the second outer insertion protruding piece 43, and the lower surface 34 of the supporting protruding piece 33 abuts on the upper surface 101 of the printed circuit board 100 to retain it. Since the portion 45 engages with the peripheral edge on the lower surface side of the insertion hole 110 (111, 112) and the printed circuit board 100 is sandwiched between the retaining portion 45 and the lower surface 34 from both sides in the insertion direction H, the terminal body 3 is printed. It can be firmly supported so as to be perpendicular to the substrate 100.

Further, since the bottom portion 46a of the recess 46 is disposed closer to the terminal body 3 side than the lower surface 34 of the support protrusion 33, the terminal body 3 and the printed circuit board 100 are connected to each other in the connected state where the lower surface 34 is in contact with the upper surface 101. A space is secured, and an electrical short circuit can be prevented when the circuit is accidentally contacted with an electric circuit (not shown) formed on the upper surface 101 of the printed circuit board 100.
