  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, front and rear, left and right, and up and down directions are based on the directions of arrows in the figure.

  Below, although the attachment component 10 which concerns on this embodiment demonstrates as what is used in order to connect the flat type conductor which is FPC20 to the connector 30 as an example, it is not limited to this. The attachment component 10 may be used to connect any flat conductor such as FFC or card edge.

  FIG. 1 is a perspective view showing a state in which two FPCs 20 are connected to the connector 30 by the attachment component 10 in a top view. FIG. 2 is a top view showing the attachment part 10, the FPC 20, and the connector 30 of FIG. FIG. 3 is an exploded perspective view showing the mounting component 10, the FPC 20, and the connector 30 of FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. FIG. 5 is a cross-sectional view taken along the line VV in FIG.

  The attachment component 10 adjusts the accommodation area of the connector 30 into which one or more FPCs 20 are inserted. In FIG. 1, as an example, the attachment component 10 is used to divide the connector 30 into two regions and connect the two FPCs 20 to the connector 30. The attachment component 10 can be inserted into and removed from the connector 30.

  As shown in FIG. 3, the FPC 20 (flat conductor) has a laminated structure in which a plurality of thin film materials are bonded to each other. The FPC 20 comprises both end portions in the longitudinal direction and is harder than the other portions, and a plurality of circuits extending linearly along the extending direction of the FPC 20 and extending to the front surface of the end reinforcing member 21. And a pattern 22. In FIG. 3, as an example, the FPC 20 having the circuit pattern 22 with 16 poles and the FPC 20 having the circuit pattern 22 with 11 poles are inserted into the connector 30. The plurality of circuit patterns 22 are arranged in a line in the left-right direction. When the FPC 20 is inserted into the connector 30, the plurality of circuit patterns 22 come into contact with first contacts 34 </ b> A and second contacts 34 </ b> B that are alternately arranged, which will be described later.

  The connector 30 includes an insulator 31 extending in the left-right direction, and a plurality of first contacts 34A (contacts) and a plurality of second contacts 34B (contacts) held alternately by the insulators 31. The connector 30 is attached on the circuit board. The connector 30 electrically connects the FPC 20 and the circuit board through the plurality of first contacts 34A and the plurality of second contacts 34B.

  The insulator 31 is formed by molding an electrically insulating and heat resistant synthetic resin material. The insulator 31 is formed in a substantially rectangular parallelepiped shape extending in the left-right direction. The insulator 31 has an accommodating portion 32 that is located at the center of the upper surface and is recessed so as to extend downward from the upper surface in the left-right direction. The accommodating part 32 receives the FPC 20 inserted into the connector 30 from above. The upper part of the accommodating part 32 is opened, and the FPC 20 can be inserted into and removed from the accommodating part 32.

  A plurality of first contact mounting grooves 33A and a plurality of second contact mounting grooves 33B extending in the vertical direction are formed on one side surface, for example, the front surface, of the accommodating portion 32 of the insulator 31 (FIGS. 4 and 4). 5). The plurality of first contact mounting grooves 33A and the plurality of second contact mounting grooves 33B are formed in a line in the left-right direction and are alternately arranged. A corresponding first contact 34A is held in each first contact mounting groove 33A. A corresponding second contact 34B is held in each second contact mounting groove 33B.

  The first contact 34A and the second contact 34B use a progressive metal mold (stamping) in the thickness direction of a thin plate of a copper alloy (for example, phosphor bronze, beryllium copper, titanium copper) or a Corson copper alloy having spring elasticity. Then, it is molded into the illustrated shape (see FIGS. 4 and 5). The first contact 34A and the second contact 34B are held in the first contact mounting groove 33A and the second contact mounting groove 33B of the insulator 31, respectively.

  The first contact 34A includes a first contact protrusion 35A that is provided at the tip of the insulator 31 and protrudes inside the insulator 31, and a first mounting part 36A that is provided at the lower end of the first contact 34A and is bent in a substantially L shape. Have. 35 A of 1st contact protrusions contact the circuit pattern 22 to which FPC20 respond | corresponds at the time of insertion of FPC20 (refer FIG. 4). The first mounting portion 36A is soldered to a corresponding circuit pattern provided on the circuit board.

  The second contact 34B has a second contact protrusion 35B provided at the tip of the insulator 31 and protruding inside the insulator 31, and a second mounting part 36B provided at the lower end of the second contact 34B and protruding downward by one step. The second contact protrusion 35B comes into contact with the corresponding circuit pattern 22 of the FPC 20 when the FPC 20 is inserted (see FIG. 5). The second mounting portion 36B is soldered to a corresponding circuit pattern provided on the circuit board.

  The procedure for connecting the two FPCs 20 to the connector 30 using the mounting part 10 is as follows (see FIG. 3). First, the attachment component 10 is inserted into a predetermined position of the housing portion 32 of the connector 30. The attachment component 10 is inserted into a corresponding position according to the number of poles of the circuit pattern 22 of the two FPCs 20. Subsequently, two FPCs 20 are inserted from above into the connector 30 in which the attachment component 10 is inserted. As described above, the attachment component 10 forms two divided regions of the connector 30 so as to correspond to the number of poles of the circuit patterns 22 of the two FPCs 20. Note that when the attachment component 10 is inserted into the connector 30, the insertion position into the connector 30 may be determined using a corresponding jig.

  FIG. 6 is a perspective view showing a single mounting component 10 according to an embodiment in a top view. 7 is a cross-sectional view taken along the arrow VII-VII in FIG. 8 is a cross-sectional view taken along the line VIII-VIII in FIG.

  The attachment component 10 includes an extending part 11 extending in the insertion direction of the FPC 20, that is, a downward direction, and a beam holding part 12 provided at the upper end of the extending part 11 and continuing to the extending part 11.

  As shown in FIGS. 7 and 8, the extending portion 11 is substantially the same as the depth of the accommodating portion 32 of the connector 30. The distal end of the extending portion 11 in the insertion direction of the FPC 20, that is, the lower end of the extending portion 11 faces the bottom surface of the housing portion 32 of the insulator 31 that constitutes the connector 30. In particular, it is preferable that the lower end of the extending portion 11 and the bottom surface of the housing portion 32 of the insulator 31 are separated from each other. The extending portion 11 is parallel to the FPC 20 in the arrangement direction of the plurality of contacts held by the insulator 31, that is, in the left-right direction (longitudinal direction of the housing portion 32), with the FPC 20 being inserted into the housing portion 32 of the connector 30. . That is, the extending portion 11 is located directly beside the FPC 20 along the left-right direction. More specifically, when the two FPCs 20 are inserted into the housing part 32, the extending part 11 is disposed in the housing part 32 so as to be sandwiched from the left and right sides by the plurality of circuit patterns 22 of the two FPCs 20. That is, the extending portion 11 and the circuit pattern 22 are arranged in a line in the left-right direction. In addition, the extending portion 11 comes into contact with any of the plurality of first contacts 34 </ b> A and the plurality of second contacts 34 </ b> B held by the insulator 31. More specifically, the extending portion 11 contacts either the first contact protrusion 35A of the plurality of first contacts 34A or the second contact protrusion 35B of the plurality of second contacts 34B.

  The beam holding part 12 is wide in the front-rear direction, and is substantially U-shaped in a side view in the left-right direction. That is, the beam holding portion 12 projects downward from the upper surface of the insulator 31 on both the front and rear sides of the insulator 31 in a state where the attachment part 10 is inserted into the housing portion 32 of the connector 30 (see FIG. 7). Further, the beam holding portion 12 includes guide portions 13 provided on the left and right side surfaces (side surfaces facing the arrangement direction of the plurality of contacts). The guide portion 13 plays a role of guiding the FPC 20 into the housing portion 32 when the FPC 20 is inserted into the connector 30.

  When the attachment component 10 is inserted into the connector 30, the vertical position of the attachment component 10 is determined based on the upper surface of the insulator 31. When the attachment component 10 is inserted into the connector 30, the portions projecting downward on both the front and rear sides of the beam holding portion 12 are arranged so as to cover the upper edge portions of the front and rear surfaces of the insulator 31.

  When the attachment part 10 is inserted into the connector 30, the extension part 11 is positioned between the first contact protrusion 35 </ b> A of the plurality of first contacts 34 </ b> A and the plurality of second contacts 34 </ b> B. It is determined by contacting any one of the second contact protrusions 35B. In other words, when the corresponding part of the extending portion 11 comes into contact with one of the plurality of first contact protrusions 35A and the plurality of second contact protrusions 35B, the attachment component 10 responds when moving in the left-right direction. It receives resistance by the elastic force of the contact. At this time, the mounting component 10 receives resistance due to the elastic force of the corresponding contact even when moving upward and downward. As a result, resistance is applied to the force to move up, down, left and right in a state where the mounting part 10 is housed in the housing portion 32, and thus the mounting part 10 cannot be easily moved.

  Since the mounting part 10 according to the present embodiment as described above can be inserted into any position of the housing portion 32 of the connector 30, versatility can be ensured. That is, the attachment component 10 can be used for connecting the FPC 20 having the circuit patterns 22 having various numbers of poles. Thus, the attachment component 10 can adjust the number of poles of the connector 30 so as to correspond to the number of poles of the FPC 20 to be connected.

  Moreover, since the extending | stretching part 11 is located in the accommodating part 32 of the connector 30, the attachment component 10 can improve the insertability to the connector 30 of FPC20. That is, the attachment component 10 can prevent the FPC 20 from being shaken or obliquely inserted during and after the insertion of the FPC 20. Thereby, the attachment component 10 can prevent contact failure between the circuit pattern 22 of the FPC 20 and the corresponding contact of the connector 30. Similarly, the attachment component 10 can also prevent the position shift of the FPC 20 in the left-right direction.

  Moreover, the attachment component 10 can reduce the cavity in the insulator 31 in which FPC20 is not inserted because the lower end of the extending | stretching part 11 opposes the bottom face of the accommodating part 32. FIG. Thereby, the attachment component 10 can suppress the penetration | invasion of the foreign material to the said cavity.

  Moreover, the attachment component 10 can implement | achieve space saving of the connector 30 because the extending | stretching part 11 is located in front of FPC20. That is, since the FPC 20 and the mounting part 10 are arranged in a line in the left-right direction, the FPC 20 is arranged in the left-right direction so as to be staggered in the front-rear direction by a mounting part having a width in the front-rear direction as described in Patent Document 1. Compared to the arrangement, the connector 30 is smaller.

  Moreover, the attachment component 10 is hold | maintained with respect to the connector 30 with the elastic force, when the extending | stretching part 11 contact | abuts the corresponding contact. Since the attachment component 10 is structured to be held by the elastic force of the corresponding contact, it can be used for the connector 30 having various numbers of poles. That is, the attachment part 10 has versatility.

  In addition, the attachment part 10 can further improve the insertability of the FPC 20 by the guide portion 13. That is, when the FPC 20 is inserted into the connector 30, one end of the attachment component 10 is fitted to the guide portion 13, thereby preventing the attachment component 10 from being inserted diagonally. Moreover, since the guide part 13 supports the end of FPC20 even after insertion of FPC20, the attachment component 10 can stabilize the insertion state of FPC20.

  It will be apparent to those skilled in the art that the present invention can be realized in other predetermined forms other than the above-described embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above description is illustrative and not restrictive. The scope of the invention is defined by the appended claims rather than by the foregoing description. Some of all changes that fall within the equivalent scope shall be included therein.

  FIG. 9 is a cross-sectional view corresponding to FIG. 7 showing a first modification. For example, as shown in FIG. 9, the extending portion 11 may have a corresponding contact, in particular, a recess 14 that engages with a contact protrusion of the corresponding contact. Thereby, the contact protrusion of the corresponding contact fits into the recess 14, and the attachment part 10 can realize an upward pull-out preventing action. At the same time, the recess 14 restricts the displacement of the mounting part 10 in the left-right direction. Moreover, in FIG. 9, although the recessed part 14 is formed only in the position vicinity corresponding to the 2nd contact protrusion 35B of the extending | stretching part 11, it is not limited to this. The recessed part 14 may be formed in the elongate rectangular shape extended to the whole up-and-down width of the extending part 11, for example. At this time, since a wider range of the contact protrusion of the corresponding contact is inserted into the recess 14, the displacement of the mounting part 10 in the left-right direction is more strongly regulated.

  FIG. 10 is a cross-sectional view corresponding to FIG. 7 showing a second modification. For example, as shown in FIG. 10, the extending portion 11 may have a corresponding contact, in particular, a convex portion 15 that engages with a contact protrusion of the corresponding contact. Thereby, when the mounting part 10 is going to move upward, the convex part 15 is caught by the corresponding contact protrusion, so that the mounting part 10 can realize an upward retaining action.

  Moreover, the attachment component 10 may be configured to have both the concave portion 14 and the convex portion 15 described above. Thereby, the attachment component 10 can strengthen further the upward prevention effect.

  FIG. 11 is a cross-sectional view corresponding to FIG. 8 showing a third modification. For example, as shown in FIG. 11, the lower end of the extending portion 11 may be positioned in a predetermined recess 37 provided on the bottom surface of the accommodating portion 32 of the insulator 31. The concave portion 37 provided on the bottom surface of the housing portion 32 is slightly wider in the left-right direction than the extending portion 11. Thereby, the position of the attachment component 10 in the left-right direction is determined. At the same time, when the mounting part 10 tries to move in the left-right direction, it collides with the side surface of the recess 37 of the insulator 31, so that it is possible to prevent the position shift in the left-right direction.

  FIG. 12 is a perspective view showing the state of attachment of the attachment component 10 according to the fourth modification to the connector 30 as viewed from above. For example, as shown in FIG. 12, the beam holding portion 12 may be formed so as to cover the entire outer frame on the upper surface of the insulator 31 from above. At this time, the beam holding portion 12 is divided into two regions in the left-right direction by the extending portion 11. That is, the beam holding portion 12 has two openings 16 as shown in FIG. The two FPCs 20 are inserted into the connector 30 through the two openings 16 from above to below. Thereby, the attachment component 10 is attached to the connector 30 in a more stable state. Moreover, since the attachment component 10 can reduce the vertical width of the beam holding portion 12, it is possible to reduce the possibility that the beam holding portion 12 and the FPC 20 collide when the FPC 20 is inserted, and to further improve the insertability of the FPC 20.

  Moreover, although the attachment component 10 according to the present embodiment has been described as being used for dividing the connector 30 into two regions and inserting the two FPCs 20, the present invention is not limited to this. For example, the connector 30 may be divided into three or more regions using a plurality of attachment parts 10. Further, the FPC 20 does not need to be inserted into all of the two or more areas divided by using the attachment component 10. The attachment component 10 may be used to insert an arbitrary number of FPCs 20 equal to or less than the divided number of regions.

  The attachment component 10 is inserted to one end of the accommodating portion 32 and used to insert one FPC 20 having the circuit pattern 22 having the number of contacts corresponding to the number of contacts held in the remaining portion of the accommodating portion 32. May be. FIG. 13 is a perspective view showing another example of use of the attachment component 10 in a top view. More specifically, as shown in FIG. 13, the attachment component 10 is inserted into the left end of the connector 30 corresponding to, for example, 40 pins, and is held by four contacts. At this time, the FPC 20 having the circuit pattern 22 with 36 poles corresponding to the remaining 36 pins is connected to the connector 30.

  Moreover, although the attachment component 10 was demonstrated as what is hold | maintained by the corresponding contact which the connector 30 has, it is not limited to this. The attachment component 10 may be held by the connector 30 by any other mechanism.
