It is preferable to arrange | position. This makes it easier to fit the socket connector with the base connector.

  In the present invention, it is preferable that a cutout portion extending in the one direction from the opening of the concave portion is formed in the upper wall portion of the base housing constituting the one space portion. As a result, a notch is formed in the upper wall of the base housing, so that even if the base connector is small, it is easy to align the socket connector with the opening of the recess of the base connector, and the user can fit the base connector and the socket connector. It becomes easy to match.

  In the present invention, the upper wall portion of the socket housing constituting the one support portion is formed with a notch portion extending from the rear end of the upper wall portion in the fitting direction with respect to the fitting direction. It is preferable that Thereby, it becomes easy to arrange | position a socket contact in one support part.

  According to the connector of the present invention, when the two connectors are fitted, one base contact and socket contact and the other base contact and socket contact are arranged so as to be shifted along one direction. The length in one direction of the partition walls can be made relatively short while ensuring the creepage distance between the contacts. For this reason, the connector can be reduced in size in one direction. Furthermore, the width of the base connector and the socket connector can be reduced in the direction along the surface of the substrate and perpendicular to one direction.

The substrate 101 has a plurality of LED elements 103 arranged in a line, and a wiring pattern (not shown) that electrically connects each LED element 103 and the base connector 1. As shown in FIG. 1, the substrate 101 is disposed such that the edge 106 of the light guide plate 105 disposed on the back surface of the liquid crystal display panel and the plurality of LED elements 103 face each other. Thereby, the light of the LED element 103 introduced from the edge 106 of the light guide plate 105 is uniformly diffused in the light guide plate 105, and the liquid crystal display panel can be illuminated uniformly. As described above, the connector 100 according to the present embodiment includes the base connector 1 mounted on the substrate 101 constituting a part of the backlight unit of the liquid crystal display panel, and the socket connector 6 corresponding thereto. The base connector 1 can be mounted not only on the substrate 101 but also on any substrate.

  As shown in FIGS. 2 to 4, the base connector 1 includes a square cylindrical base housing 2 and two base contacts 3 and 4 accommodated in the base housing 2. For convenience of description of the base connector 1, as shown in FIGS. 2 and 4, the left end portion of the base connector 1 is a rear end portion (one end portion) and the right end portion is a front end portion (the other end portion). To do.

  The base housing 2 is made of an insulating synthetic resin. Further, as shown in FIG. 4, the base housing 2 has a concave portion 11 that opens toward the front (one direction and rightward in the figure), and is located in the concave portion 11 from the rear end wall 12 to the front. A partition wall 13 protruding toward the top is provided. As shown in FIG. 3, the partition wall 13 is formed in the center of the rear end wall 12. That is, in the recess 11, two space portions 11 a and 11 b that are divided up and down by the partition wall 13 are formed. These two space portions 11a and 11b have a shape in which two support portions 31 and 35 (described later) of the socket connector 6 can be fitted. Further, as shown in FIG. 4, the partition wall 13 is disposed between contact portions 21 and 25 (described later) of the two base contacts 3 and 4. That is, the contact part 21 is arrange | positioned in one space part 11a among the two space parts 11a and 11b, and the contact part 25 is arrange | positioned in the other space part 11b. The tip of the partition wall 13 is located in the vicinity of the tip of the contact portion 25 and behind the tip of the contact portion 25. That is, the tip end of the partition wall 13 is disposed in front of the tip end of the contact portion 21.

  As shown in FIG. 2, the base housing 2 has a rear end at the rear end of both side walls in the width direction (horizontal direction) perpendicular to the front-rear direction of the base housing 2 toward the rear. Two pairs of protruding protrusions 14 and 15 are formed. The pair of protrusions 14 are formed from the upper end to the center of both side walls in the vertical direction. The other pair of protrusions (protection portions) 15 are formed at the lower ends of the side walls.

  As shown in FIGS. 2 and 3, a pair of protrusions (protection portions) 16 protruding forward are formed at the front ends of both side walls of the base housing 2. The pair of protrusions 16 are formed at the lower ends of both side walls. Between these pairs of protrusions 15 and 16, lead portions 22 and 26 (extending portions 22a and 26a) of base contacts 3 and 4 to be described later are arranged. Thereby, it becomes difficult to apply an impact to the lead portions 22 and 26 from the outside, and the lead portions 22 and 26 can be protected.

  A cutout portion 18 is formed at a front portion of the upper wall portion 17 of the base housing 2 that defines the space portion 11a. The notch 18 extends rearward from the opening of the recess 11 to the center of the upper wall 17. Accordingly, even if the base connector 1 is small, the front end portion of the socket connector 6 corresponding to the base connector 1 can be easily visually aligned with the opening of the concave portion 11 of the base connector 1, and the user can easily connect the base connector 1 and the socket connector 6 to each other. It becomes easy to fit. In addition, the user can check the joining state of the extension portion 26 a on the opening side of the recess 11 of the base connector 1 and the substrate 101 by the solder 102 from the upper wall portion 17 side of the base connector 1.

  In addition, the rear portion of the upper wall portion 17 of the base housing 2 is also formed by removing a part of the upper wall portion 17 so that a hook 51 provided on the socket housing 7 described later can be locked. A portion 19 is formed. The hook portion 19 extends forward from the rear end of the upper wall portion 17.

  One base contact 3 of the two base contacts 3 and 4 is manufactured by punching and bending a conductive metal plate. As shown in FIGS. The lead part 22 to be soldered, the two fixing parts 23a and 23b for fixing the base contact 3 to the base housing 2, and the connecting part 21, the lead part 22 and the fixing parts 23a and 23b are connected to extend in the vertical direction. Part 24.

  As shown in FIG. 5, the contact portion 21 extends from the upper end portion of the connecting portion 24 along the width direction orthogonal to the extending direction (vertical direction) of the connecting portion 24, and the tip portion projects forward. In this way, the middle portion is bent by 90 °. Further, as shown in FIGS. 4 and 9, the contact portion 21 is disposed in one space portion 11 a disposed above the partition wall 13 and far from the surface 101 a of the substrate 101. That is, the contact portion 21 extends along the front-rear direction so as to protrude into the space portion 11 a from the hole 12 a of the rear end wall 12 when the base contact 3 is fixed to the base housing 2. Further, the contact portion 21 has such a length that the tip is disposed in the vicinity of the center of the base housing 2 in the front-rear direction. Moreover, the contact part 21 has the latching | locking part 21a latched by the recessed part 12c formed in the inner surface of the hole 12a, as shown in FIGS. For this reason, when the contact portion 21 is inserted into the hole 12 a, the locking portion 21 a is locked to the recess 12 c and contributes to the fixing of the base contact 3 to the base housing 2. In addition, although the shape of the contact part 21 of this embodiment is plate shape, what kind of shapes, such as a prism, a cylinder, and a hollow, may be sufficient.

  As shown in FIG. 5, the fixing portion 23 a extends from the center in the extending direction of the connecting portion 24 along the width direction of the connecting portion 24, and the tip portion protrudes in the same direction as the contact portion 21. The middle part is configured by being bent by 90 °. Similarly, the fixing portion 23b is slightly different in shape from the fixing portion 23a. Similarly, the fixing portion 23b extends along the width direction from the center of the connecting portion 24, and the tip portion protrudes in the same direction as the contact portion 21. Is bent by 90 °. As shown in FIG. 6, the upper and lower surfaces of the front end portions of the fixing portions 23a and 23b are formed on the inner surface of the hole 12b when the front end portions are inserted into the two holes 12b formed in the rear end wall 12. Eight engaging portions 23c are formed to be engaged with the recessed portions (not shown). Thereby, the base contact 3 can be fixed to the base housing 2.

  The lead portion 22 extends along the width direction of the base housing 2 and connects the extending portion 22a whose lower surface and its peripheral edge are joined to the substrate 101 by soldering, and the extending portion 22a and the lower end of the connecting portion 24. And a curved portion 22b. The curved portion 22b is bent 90 ° rearward from the lower end of the connecting portion 24 so that the in-plane direction on the lower surface of the extending portion 22a includes a direction parallel to the protruding direction of the contact portion 21.

  The extending part 22a has two protruding parts 22c that protrude rearward from both ends in the extending direction. That is, a concave portion 22d that is recessed in the width direction of the extending portion 22a (the direction orthogonal to the extending direction and the front-rear direction) is formed at the center of the extending portion 22a. As described above, since the recessed portion 22d is formed in the extending portion 22a, the peripheral length of the extending portion 22a is longer than that in which the recessed portion 22d is not formed, and the solder 102 in the extending portion 22a is formed. The adhesion distance becomes longer. Therefore, it is possible to improve the bonding strength of the base connector 1 to the substrate 101.

  Moreover, the length of the extending part 22a in the extending direction is longer than the length in the width direction (front-rear direction) orthogonal to the extending direction of the extending part 22a, as shown in FIGS. The extension 22 a is long and can be disposed between the pair of protrusions 15. That is, the extending part 22a is disposed within a range defined by both side surfaces of the base housing 2 in the width direction. As a result, when the plurality of base connectors 2 are arranged in parallel on the substrate, the extending portions 22a do not come into contact with each other even if they are arranged adjacent to each other so as to be in close contact with each other. Therefore, a plurality of base connectors 2 can be arranged adjacently in parallel on the substrate 101 without forming a gap between the base connectors 1. Further, since the extending portion 22a is disposed between the pair of protrusions 15, the distance between both side surfaces of the base housing 2 and both ends of the extending portion 22a is relatively separated in the width direction of the base housing 2. For this reason, even if the solder 102 which joins the extension part 22a to the board | substrate 101 spreads a little around the extension part 22a, it can suppress that adjacent extension part 22a short-circuits.

  Similarly to the base contact 3, the other base contact 4 is manufactured by punching and bending a conductive metal plate. As shown in FIGS. 4, 7, and 8, the contact portion 25 and the substrate 101 are soldered. A lead portion 26 to be attached, a fixing portion 27 that fixes the base contact 4 to the base housing 2, and a connecting portion 28 that connects the contact portion 25, the lead portion 26 and the fixing portion 27. At the lower end of the connecting portion 28, a curved portion 28 a that is bent in the width direction of the base housing 2 and then further bent forward is connected to the lead portion 26.

  The contact portion 25 is formed so as to protrude forward from the upper end portion of the connecting portion 28. Further, as shown in FIGS. 4 and 9, the contact portion 25 is disposed in the other space portion 11 b disposed below the partition wall 13 and close to the surface 101 a of the substrate 101. That is, the contact portion 25 projects into the space portion 11b along the front-rear direction when the base contact 4 is fixed to the base housing 2.

  Specifically, the contact portion 25 extends forward from the vicinity of the center of the base housing 2 in the front-rear direction. Further, the contact portion 25 has a length that can protrude forward from the tip of the partition wall 13 in the space portion 11b. Thus, the contact portion 25 of the base contact 4 is disposed in front of the contact portion 21 of the base contact 3 in the space portion 11b. In other words, the contact portion 21 is disposed at a position recessed behind the contact portion 25 (in the fitting direction of the socket connector 6 with respect to the base connector 1) in the space portion 11a. That is, both the contact parts 21 and 25 are displaced from each other in the front-rear direction. As a result, the creepage distance between the contact portions 21 and 25 in the recess 11 can be increased. Further, both contact portions 21 and 25 are arranged in the vertical direction, that is, in the direction perpendicular to the surface 101 a of the substrate 101. Thereby, the user can easily check the state (whether there is deformation or damage) of both the contact portions 21 and 25. Further, since both contact portions 21 and 25 are arranged vertically, the width of the base connector 1 can be reduced in the direction along the surface 101a of the substrate 101 and in the width direction of the base housing 2. . Further, since the socket connector 6 described later also corresponds to the base connector 1, the socket contacts 8 and 9 are arranged in the vertical direction, and the width can be reduced similarly to the base connector 1. Since the widths of the connectors 1 and 6 can be reduced in this way, the width of the substrate 101 can be reduced as shown in FIG. When the width of the substrate 101 can be reduced, the LED element 103 having a small width or the light guide plate 105 having a small thickness can be employed, and the thickness of the entire backlight unit can be reduced. . In addition, the contact part 25 of this embodiment may be in any shape such as a prism, a cylinder, and a hollow, like the contact part 21.

  The fixing portion 27 is formed so as to protrude rearward from the upper end portion of the connecting portion 28. Further, as shown in FIG. 4, two locking portions 27 a that are locked to the two concave portions 13 a formed on the lower surface of the partition wall 13 are formed on the upper surface of the fixing portion 27. Thereby, the base contact 4 can be fixed to the base housing 2.

  The lead portion 26 extends along the width direction of the base housing 2, and an extended portion 26 a whose lower surface and its peripheral edge are joined to the substrate 101 by the solder 102, and a curved portion 28 a of the extended portion 26 a and the connecting portion 28. And a curved portion 26b connecting the two. The curved portion 26b has a shape extending from the curved portion 28a so that the in-plane direction on the lower surface of the extended portion 26a includes a direction parallel to the protruding direction of the contact portion 25.

  The extending portion 26a has two protruding portions 26c that protrude forward from both ends in the extending direction. That is, in the center of the extending direction of the extending part 26a, a recessed part 26d that is recessed in the width direction of the extending part 26a (the direction orthogonal to the extending direction and the front-rear direction) is formed. As described above, since the recessed portion 26d is formed in the extending portion 26a, the attachment distance of the solder 102 on the extending portion 26a is increased. Therefore, it is possible to further improve the bonding strength of the base connector 1 to the substrate 101.

  The length of the extending portion 26a in the extending direction is longer than the length in the width direction (front-rear direction) orthogonal to the extending direction of the extending portion 26a, and the extending portion 26a is a pair of protrusions 16. The length can be placed between them. That is, the extending portion 26 a is also disposed within a range defined by both side surfaces of the base housing 2 in the width direction. Therefore, similarly to the above, the plurality of base connectors 2 can be arranged adjacent to each other in parallel (arranged with the side surfaces in contact with each other). Further, since the extending portion 26 a is disposed between the pair of protrusions 16, the distance between the both side surfaces of the base housing 2 and both ends of the extending portion 26 a is relatively long with respect to the width direction of the base housing 2. For this reason, even if the solder 102 that joins the extending portion 26a to the substrate 101 spreads slightly around the extending portion 26a, it is possible to suppress the adjacent extending portions 26a from being short-circuited.

  Next, the socket connector 6 that can be fitted into the recess 11 of the base connector 1 will be described below with reference to FIGS. As shown in FIGS. 9 to 12, the socket connector 6 includes a socket housing 7 that is inserted into and fitted into the recess 11, and two socket contacts that are connected to the two electric wires 10 and are accommodated in the socket housing 7. 8 and 9 are included. The socket contacts 8 and 9 are accommodated in the socket housing 7 so that the contact portions 21 and 25 are inserted when the socket housing 7 and the base housing 2 are fitted together. Further, the socket contacts 8 and 9 may have any shape as long as the contact portions 21 and 25 can be inserted when the connectors 1 and 6 are fitted. For convenience of explanation, the socket connector 6 will be described below with the left end portion of the socket connector 6 as the front end portion and the right end portion as the rear end portion, as shown in FIGS.

  The socket housing 7 is made of an insulating synthetic resin. 10 to 12, the socket housing 7 has two cylindrical support portions 31 and 35 that surround the socket contacts 8 and 9 and support the socket contacts 8 and 9, respectively. ing. Socket contacts 8 and 9 connected to the electric wire 10 from the rear end side of the socket housing 7 are inserted into the support portions 31 and 35 and accommodated in the support portions 31 and 35. Further, the front end walls 32 and 36 of the support portions 31 and 35 are formed with openings 33 and 37 through which the contact portions 21 and 25 pass when the connectors 1 and 6 are fitted.

  Among these support portions 31 and 35, the support portion 31 is disposed above, and the support portion 35 is formed integrally from the center in the front-rear direction of the support portion 31 to the rear end thereof. That is, in a state where the socket connector 6 is fitted to the base connector 1 mounted on the substrate 101, the tip (front end) of one support portion 31 disposed at a position far from the surface 101a of the substrate 101 is the base housing 2. The socket housing 7 is disposed so as to protrude from the tip (front end) of the other support portion 35 along the fitting direction of the socket housing 7 (the direction from right to left in FIG. 9). , 11b, and shifted in the fitting direction (front-rear direction). Further, the socket contacts 8 and 9 are also shifted in the fitting direction (front-rear direction) in accordance with the positional relationship between the contact portions 21 and 25. As described above, the support portion 31 located on the upper side is arranged so as to be shifted from the support portion 35 so as to protrude forward in the fitting direction, so that the socket connector 6 can be easily fitted to the base connector 1 visually. Further, two space portions 11 a and 11 b corresponding to the support portions 31 and 35 are formed in the base housing 2, and the contact portion 21 is disposed at a position recessed rearward from the contact portion 25, so that the socket connector is further improved. 6 is easily fitted into the base connector 1.

  In the socket housing 7, a partition wall 30 is formed between the two socket contacts 8 and 9, which is a portion of the lower wall portion of the support portion 31 and the upper wall portion of the support portion 35. As shown in FIG. 9, the partition wall 30 is formed so as to overlap with the partition wall 13 of the base housing 2 in the fitting direction (front-rear direction: one direction) when both the connectors 1 and 6 are fitted. .

  Further, as shown in FIGS. 9 and 12, a notch 42 is formed in the rear portion of the upper wall portion 41 of the socket housing 7 constituting the support portion 31. The notch 42 extends from the rear end of the upper wall 41 to the vicinity of the center in the fitting direction. By forming the cutout portion 42 in this manner, the socket contact 8 connected to the electric wire 10 can be easily placed (inserted) in the support portion 31.

  Further, on the upper surface of the upper wall portion 41 of the socket housing 7, as shown in FIG. 9, a hook 51 that can be locked to the hook portion 19 of the base housing 2 when the socket connector 6 and the base connector 1 are fitted. Is provided. Thereby, when both the connectors 1 and 6 are fitted, they can be locked so as not to be separated from each other. As shown in FIG. 12, the hook 51 is integrally connected to the rear wall portion and the upper wall portion 41 with respect to the front-rear direction. The hook 51 can swing up and down with this connecting portion as a fulcrum. For this reason, when the both connectors 1 and 6 are fitted together, the front end of the hook 51 is pressed to the upper wall portion 41 by pressing the rear end of the hook 51 locked to the hook portion 19 in a direction approaching the upper wall portion 41. And the hook 51 is released from the hooked portion 19. In this way, it is possible to release the fitting of both connectors 1 and 6.

  As described above, according to the base connector 1 of the present embodiment, the lead portion 26 is disposed at the front end portion (the other end portion) of the base housing 2, and the lead portion 22 is disposed at the rear end portion (one end portion) of the base housing 2. Therefore, the creepage distance required for insulation between the lead portions 22 and 26 can be ensured. In addition, lead portions 22 and 26 constituting part of the base contacts 3 and 4, which are soldered to the substrate 101, are disposed at the front end portion and the rear end portion of the base housing 2. Thus, it is not necessary to provide the base connector 1 with reinforcing ribs different from the lead portions 22 and 26. For this reason, the increase in a number of parts can be suppressed and the manufacturing cost of the base connector 1 can be reduced. Further, since the lead portions 22 and 26 are arranged at the front end portion and the rear end portion of the base housing 2, when the socket connector 6 is fitted to the base connector 1, as shown in FIG. The upper part of the lead part 26 arranged at the front end of the socket connector 6 is covered with the socket connector 6. In other words, the lead portion 26 is disposed at a position where the upper portion thereof is covered by the socket connector 6 when both the connectors 1 and 6 are fitted. For this reason, the lead part 26 is protected by the socket connector 6. Further, the protection of the lead portion 26 by the socket connector 6 is also used for the fitting operation of both the connectors 1 and 6.

  Further, since the lead portions 22 and 26 have the extending portions 22a and 26a, the base connector 1 is joined to the substrate 101 by the solder 102 while ensuring a creepage distance necessary for insulation between the lead portions 22 and 26. Strength can be improved. Furthermore, since both the lead parts 22 and 26 have the extension parts 22a and 26a, the joint strength of the base connector 1 with respect to the board | substrate 101 can be improved effectively.

  The connector 100 of the present embodiment has a configuration including the base connector 1 having the above-described effects and a socket connector 6 that is a pair of the base connector 1. Further, when both connectors 1 and 6 are fitted to both housings 2 and 7, they are fitted between one base contact 3 and socket contact 8 and the other base contact 4 and socket contact 9. The partition walls 13 and 30 are provided so as to overlap each other with respect to the direction, and one base contact 3 and the socket contact 8 and the other base contact 4 and the socket contact 9 are shifted from each other with respect to the fitting direction. As described above, the length of the partition walls 13 and 30 in the fitting direction is compared because the one contact 3 and 8 and the other contact 4 and 9 are arranged so as to be shifted in the fitting direction (one direction). Can be shortened. Specifically, the length in the fitting direction of the partition walls 13 and 30 is a length that secures a creepage distance between the one contact 3 and 8 and the other contact 4 and 9, as shown in FIG. The amount of overlap of the partition walls 13 and 30 in the fitting direction is smaller than the amount of shift in the fitting direction between one base contact 3 (or socket contact 8) and the other base contact 4 (or socket contact 9). It becomes the length. For this reason, it is possible to reduce the size of the connector 100 in the fitting direction. Further, the connector 100 is provided with a creeping distance necessary for insulation at the boundary between the partition walls 13 and 30 between the one contact 3 and 8 and the other contact 4 and 9. Is improved, and it becomes difficult to short-circuit between one and the other contacts.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, in the above-described embodiment, the support portion 31 protrudes forward from the support portion 35, but the support portion disposed at a position close to the surface 101 a of the substrate 101 is disposed at a position far from the surface 101 a. You may protrude ahead rather than the front end of a part. In this case, the positional relationship in the front-rear direction of the base contacts 3 and 4 and the socket contacts 8 and 9 is also opposite to the above. Further, the cutout portion 18 may not be formed in the upper wall portion 17 of the base housing 2. Further, the notch 42 may not be formed in the upper wall portion 41 of the socket housing 7.
