  By the way, in the connector shown in FIG. 9 of Patent Document 1, for example, if the amount of solder when the terminals are soldered to the substrate increases, the following problems may occur. Specifically, when soldering the terminals to the board, the liquid solder before solidification enters the slight gap between the bottom surface of the housing and the board by capillary action and short-circuits the adjacent terminals. There is a risk of being lost. Such a problem is likely to occur in a female terminal having a complicated terminal shape.

  The present invention is to solve the above problems, and an object thereof is to provide a connector having a configuration capable of preventing a short circuit between adjacent terminals, and a terminal having a configuration capable of preventing a short circuit between adjacent terminals. To provide a formed hoop material.

  Further, as described above, when a connector is formed by using two types of male terminals having different lengths from each other, it is necessary to manage the male terminals by type, which increases management man-hours.

  The present invention is to solve the above problems, and an object thereof is to standardize a male terminal used for a connector having male terminals having different projecting lengths with reference to a predetermined portion of a connector housing. ..

  (1) In order to solve the above problems, a connector according to an aspect of the present invention includes a connector housing body portion, a pair of press-fitting portions that are press-fitted into the connector housing body portion, and a pair of press-fitting portions. A connector provided with a plurality of female terminals, each of which has a lead portion which is integrally formed with one side and which is a portion to be soldered to a substrate, wherein the connector housing main body portion has the connector. A protruding portion is formed so as to protrude downward from the housing main body portion, and a tip end portion of the connector main body portion contacts the substrate when the connector is mounted on the substrate. Is larger than the distance between the press-fitting portions of the two female terminals that are adjacent to each other in the state of being attached to the connector housing body portion.

  With this configuration, when the connector is mounted on the board, a gap is formed at a predetermined distance between the bottom surface of the connector housing body and the board. The size of the gap is equal to the amount of downward protrusion of the protrusion with respect to the bottom surface of the connector housing body. That is, by providing the above-mentioned protruding portion on the connector housing main body portion, a gap can be formed between the bottom surface of the connector housing main body portion and the substrate. This gap is larger than the distance between the press-fitting portions of two adjacent female terminals.

  For example, if the gap between the bottom surface and the substrate is smaller than the distance between the press-fitting portions of two adjacent female terminals, the following problems may occur. Specifically, when soldering the female terminals to the substrate, liquid solder before solidification intrudes into a slight gap between the bottom surface of the housing and the substrate by a capillary phenomenon, so that adjacent female terminals are There is a risk of short-circuiting.

  In this regard, in this configuration, the gap between the bottom surface of the connector housing body and the substrate is larger than the distance between the press-fitting portions of the adjacent female terminals. With this configuration, even when liquid solder flows from the lead portion side to the press-fitting portion side during soldering, the solder does not easily reach the press-fitting portion. Further, even when the solder reaches the press-fitting portion, the width of the path until the liquid solder reaches the press-fitting portion of the adjacent female terminal (that is, the gap between the bottom surface of the housing body and the substrate). Because of its large size, capillarity is unlikely to occur. This makes it difficult for the liquid solder to reach the press-fitting portion of the adjacent female terminal, so that a short circuit between the adjacent female terminals does not easily occur.

  Therefore, according to this structure, it is possible to provide a connector having a structure capable of preventing a short circuit between adjacent terminals.

  (2) Preferably, one of the pair of press-fitting portions is a lead-portion-side press-fitting portion in which the lead portion is integrally formed, and the other of the pair of press-fitting portions is a non-lead-portion-side press-fitting portion. In addition, a recessed portion that is recessed upward from below is formed in the press-fitting portion on the side opposite to the lead portion.

  With this configuration, even if the liquid solder flows from one female terminal to the adjacent female terminal side and tries to reach the non-lead-side press-fitted portion of the female terminal, a concave portion is formed in that portion, so that the anti-lead is not formed. It is difficult to reach the press-fitting part on the side. That is, according to this structure, a short circuit between adjacent terminals can be prevented more reliably.

  (3) In order to solve the above problems, a connector according to an aspect of the present invention includes a plurality of male terminals and a connector housing having a plurality of through-holes into which the plurality of male terminals are press-fitted. A connector to be fitted with a mating connector, wherein the plurality of male terminals have the same shape and the same size, and at least one male terminal of the plurality of male terminals is based on a predetermined portion of the connector housing. The protrusion length that is the length to the tip of the male terminal is longer than the protrusion length of the other male terminals.

  According to this configuration, the plurality of male terminals in the connector having the plurality of male terminals having different protruding lengths are configured by using a plurality of male terminals having the same shape and the same size, that is, one type of male terminal. be able to.

  Therefore, according to this structure, the male terminal used for manufacturing a connector having male terminals having different protruding lengths with respect to a predetermined portion of the connector housing can be shared.

  (4) In order to solve the above problems, a connector according to an aspect of the present invention is a connector housing in which a plurality of spaces partitioned by a plurality of partition walls are arranged in a predetermined direction, and two adjacent partition walls. A plurality of female terminals each having a pair of press-fitting portions that are press-fitted or press-fitted into, and a connecting portion that connects the pair of press-fitting portions, each of which has the female terminal. A cutting portion, which is a cutting portion between a carrier connecting the plurality of female terminal portions in the hoop material on which a plurality of female terminal portions that are constituents is formed, is formed in the connecting portion.

  For example, when the cutting portion in this configuration is formed in one of the pair of press-fitting portions of the female terminal (that is, when the carrier of the hoop material is connected to the portion corresponding to the press-fitting portion of the female terminal portion). ), The following problems may occur. Specifically, when thread-like burrs, so-called whisker burrs, are formed by cutting between the carrier and the female terminal portion, the press-fitting portion is a female terminal adjacent to the female terminal having the press-fitting portion and a partition wall. Since they are adjacent to each other, the distance to the adjacent female terminal is very short. Then, the whisker burr easily contacts the adjacent female terminal, and a short circuit between the female terminals easily occurs.

  In this regard, the cutting portion in this configuration is formed at the connecting portion of the female terminal. Since the connecting portion is relatively distant from the female terminal adjacent to the female terminal having the connecting portion, even if a whisker burr is generated at the connecting portion, it is difficult to contact the adjacent female terminal.

  Therefore, according to this structure, a short circuit between adjacent terminals can be prevented.

  (5) In order to solve the above problems, a hoop material according to an aspect of the present invention includes a carrier having a band-shaped portion formed in a band shape and a plurality of connecting portions integrally formed with the band-shaped portion, A hoop member comprising a female terminal portion integrally formed with the connecting portion, wherein the female terminal formed by cutting the female terminal portion at the connecting portion is partitioned by a plurality of partition walls. And a pair of press-fitting portions that can be press-fitted into the two adjacent partition walls of the connector housing in which the plurality of spaces are arranged in a predetermined direction, and a connecting portion that connects the pair of press-fitting portions. The band-shaped portion and the connecting portion are connected to each other.

  For example, when the connecting portion of the hoop material connects the strip portion and the press-fitting portion, the following problems may occur. Specifically, when a thread-like burr, so-called whisker burr, is generated by cutting the connecting portion, the press-fitting portion is adjacent to the female terminal adjacent to the female terminal having the press-fitting portion with a partition wall therebetween. Therefore, it is very close to the adjacent female terminal. Then, the whisker burr easily contacts the adjacent female terminal, and a short circuit between the female terminals easily occurs.

  In this respect, the connecting portion in this configuration connects the strip-shaped portion and the connecting portion. Since the connecting portion is relatively distant from the female terminal adjacent to the female terminal having the connecting portion, even if a whisker burr is generated at the connecting portion, it is difficult to contact the adjacent female terminal.

  Therefore, according to this structure, a short circuit between adjacent terminals can be prevented.

  According to the present invention, a short circuit between adjacent terminals can be prevented. Further, according to the present invention, it is possible to share a male terminal used for a connector having male terminals having different protruding lengths with respect to a predetermined portion of the connector housing.

Similarly to the right side base 52, the left side base 53 is also a plate-shaped portion formed in a rectangular shape elongated in the front-rear direction when viewed from the left-right direction. The left side base portion 53 is provided on the left side of the right side base portion 52 with a predetermined distance from the right side base portion 52. The connecting portion 54 is provided as a portion that connects the front-side end of the right-side base 52 and the front-side end of the left-side base 53. That is, the connecting portion 54 is provided as a portion between the right side base portion 52 and the left side base portion 53. The height (the length in the vertical direction) of the connecting portion 54 is the same as the height of the right base portion 52 and the left base portion 53.

  The above-mentioned cutting part 76 is formed in the connecting part 54. The cutting portion 76 is formed at the central portion in the left-right direction at the lower end portion of the connecting portion 54. In the present embodiment, the plating process is applied to the portion of the female contact 50 other than the cut portion 76. That is, in the surface portion of the female contact 50, only the cut portion 76 is not plated. Arc-shaped recesses 54a are formed on both ends of the cutting portion 76.

  The pair of leaf spring portions 55, 56 has a right leaf spring portion 55 and a left leaf spring portion 56. The right side leaf spring portion 55 has a base end side portion (lower side portion) integrally provided with an upper end portion of the right side base portion 52. The left side leaf spring portion 56 has a base end side portion (lower side portion) integrally provided with an upper end portion of the left side base portion 53. That is, each leaf spring portion 55, 56 is formed in a cantilever shape with the base end side portion serving as a fulcrum.

  A slit portion 57 is formed in each of the leaf spring portions 55 and 56. Each slit portion 57 extends downward from the upper end portion of each leaf spring portion 55, 56 to a portion slightly closer to the base end side than the central portion in the vertical direction of each leaf spring portion 55, 56. As a result, the tip end side (upper end side) of each of the leaf spring portions 55 and 56 is divided in the front-rear direction. The pair of leaf spring portions 55 and 56 are configured to hold the contact main body portion 22 of the male contact 20 while sandwiching the male connector 2 and the female connector 3 in a fitted state. By thus forming the slit portion 57 in the leaf spring portions 55 and 56, the holding force of the male contact 20 by the pair of leaf spring portions 55 and 56 can be adjusted. Specifically, when the holding force of the male contact 20 by the pair of leaf springs in the state where the slit portion 57 is not formed is too large, the holding force is increased by forming the slit portion 57 as described above. Can be weakened.

  The lead portion 58 is formed integrally with the base portion 51. The lead portion 58 is formed in a tab shape extending downward from the lower end portion of the left base portion 53. The lead portions 58 have the same shape as each other. In the present embodiment, two lead portions 58 are formed with a space in the front-rear direction.

[About female connector]
Referring to FIG. 7, the female contact 50 is held in the female connector housing 30 as follows. Specifically, the right base portion 52 and the left base portion 53 of each female contact 50 are in a state of being press-fitted into the pair of partition walls 37, 37 that are adjacent in the left-right direction. That is, the right side base portion 52 and the left side base portion 53 are provided as press-fitting portions 59 and 61 that are press-fitted into the pair of partition walls 37 and 37 that are adjacent to each other in the left-right direction. The right side base portion 52 is provided as a non-lead portion side press-fitting portion 59 formed on the side far from the lead portion 58, and the left side base portion 53 is provided as a lead portion side press-fitting portion 61 formed on the side close to the lead portion 58. ing.

  In the female connector 3, the pair of press-fitting portions 59 and 61 of each female contact 50 are press-fitted into the pair of partition walls 37, so that the pair of leaf spring portions 55 and 56 and the press-fitting portion 59, as shown in FIG. 61 and the connecting portion 54 are housed in each housing space S, and the lead portion 58 is provided so as to extend downward from the bottom surface 31 a of the connector housing main body portion 31.

  Further, with reference to FIG. 7, the lead portion 58 is fixed to the substrate Sb by soldering in a state where the lead portion 58 is inserted into the lead portion through hole portion 85 of the substrate Sb and the portion exposed downward through the substrate Sb. ..

  Further, in the female connector 3, referring to FIG. 7, a reinforcing tab 48 is provided so as to extend in the up-down direction so as to straddle both the substrate Sb and the female connector housing 30. Specifically, the reinforcing tab 48 is press-fitted into the reinforcing tab hole 44 from the lower side to the upper side through the through hole 86 for the reinforcing tab. In this state, the portion of the reinforcing tab 48 exposed from the lower surface of the board Sb is soldered to the board Sb. Thereby, the female connector housing 30 can be more firmly fixed to the substrate Sb. Thus, the reinforcing tab 48 can be press-fitted from the lower side to the upper side via the substrate Sb. With such a configuration, the press-fitting direction of the reinforcing tab 48 and the press-fitting direction of the female contact 50 with respect to the female connector housing 30 can be aligned, so that workability at the time of assembly can be improved.

  In the female connector 3, the pair of leaf spring portions 55 and 56 sandwich and hold the contact body portion 22 of the male contact 20 in a state where the male connector 2 and the female connector 3 are fitted to each other. Specifically, when the male connector 2 and the female connector 3 are fitted to each other, although not shown, the contact body portion 22 of the male contact 20 is inserted between the pair of leaf spring portions 55 and 56, and the pair of leaf spring portions 55 and 56 are inserted. The leaf spring portions 55 and 56 are pushed outward (in the direction in which the pair of leaf spring portions 55 and 56 are separated from each other). As a result, a restoring force acts on the pair of leaf spring portions 55 and 56, so that the contact body portion 22 of the male contact 20 is sandwiched and held by the pair of leaf spring portions 55 and 56. As a result, the male contact 20 and the female contact 50 come into contact with each other, so that the male connector 2 and the female connector 3 are electrically connected.

[About the gap between the bottom of the connector housing body and the board]
By the way, referring to FIG. 7, in the protrusion 42 of the present embodiment, as described above, the downward protrusion amount L3 with the bottom surface 31a of the connector housing body 31 as the reference plane P2 is 0.6 mm. Is set to. As a result, the gap dimension a between the bottom surface 31a of the connector housing body 31 and the board Sb when the female connector 3 is mounted on the board Sb is also 0.6 mm. On the other hand, in this embodiment, the thickness of the partition wall 37 is set to 0.5 mm. Therefore, the lead portion side press-fitting portion 61 of one (for example, the right side in FIG. 7) female contact 50 that is adjacent to the partition wall 37 and the non-lead portion side press-fitting portion of the other (for example, the left side in FIG. 7) female contact 50. The distance b to 59 is 0.5 mm. That is, in this embodiment, the gap dimension a is set to be larger than the distance b. The reason why the dimensions a and b are set as described above will be described below.

  FIG. 13 is an enlarged cross-sectional view near the board Sb and the lead portion 58 of the female connector 3 according to the present embodiment, which is a diagram for explaining the behavior of the solder Sd when the lead portion 58 is soldered to the board Sb. FIG. 13 (A) is a diagram showing the state of the solder Sd immediately after the start of soldering, and FIG. 13 (B) is a diagram showing the state of the solder Sd after some time has elapsed from the start of soldering. . Further, FIG. 20 is an enlarged cross-sectional view of the conventionally known female connector 100 near the substrate Sb and the lead portion 58. The behavior of the solder Sd when the lead portion 58 is soldered to the substrate Sb will be described. 20A is a diagram showing a state of the solder Sd immediately after the start of soldering, and FIG. 20B is a diagram showing a state of the solder Sd after a lapse of time from the start of soldering. ,. 13 and 20, an example of performing soldering using the soldering iron 105 and the thread solder 106 is shown. In addition, FIGS. 13B and 20B illustrate an example in which the amount of soldered solder is slightly large.

  In the conventionally known female connector 100, as shown in FIGS. 20 (A) and 20 (B), the gap dimension c between the bottom surface 31a of the connector housing main body portion and the substrate Sb is relatively small, or Alternatively, no gap is formed. Specifically, the clearance dimension c is smaller than the distance b shown in FIG.

  In such a conventional configuration, when the amount of soldering when the operator solders the lead portion 58 to the substrate Sb becomes large, the liquid solder Sd forms the lead portion 58 and the lead portion through hole portion 85. It protrudes to the front side (upper side) of the substrate Sb through the gap between them. Then, in the conventional configuration, since the clearance dimension c is small, the liquid solder Sd reaches the bottom surface 31a of the connector housing main body immediately. Then, after that, the liquid solder Sd is attracted to the left side by the capillary phenomenon and reaches the right side base portion 52 of the adjacent female contact 50 (see FIG. 20B). As a result, the adjacent female contacts 50 are short-circuited with each other.

  In this respect, the female connector 3 according to the present embodiment is unlikely to cause the above-mentioned short circuit problem.

  Specifically, with reference to FIG. 13A, in the female connector 3 according to the present embodiment, when the operator solders the lead portion 58 to the substrate Sb, the soldering amount increases, As in the case of the conventional configuration, the liquid solder Sd runs off to the front side (upper side) of the substrate Sb through the gap between the lead portion 58 and the lead portion through hole portion 85. However, in the female connector 3, since the gap dimension a is set to be larger than the distance b, it is difficult for the liquid solder Sd to reach the bottom surface 31a of the connector housing body 31 (see FIG. 13B). As a result, adjacent female contacts 50 are less likely to short-circuit.

  Further, in the female connector 3, the gap dimension a is set larger than the distance b as described above. Then, even if the liquid solder Sd reaches the bottom surface 31a of the connector housing main body portion 31, the capillary phenomenon is unlikely to occur and it is difficult to be attracted to the adjacent female contact 50. As a result, adjacent female contacts 50 are less likely to short-circuit.

[effect]
As described above, in the female connector 3 of the electrical connection device 1 according to the present embodiment, when the female connector 3 is mounted on the board Sb, a predetermined distance is provided between the bottom surface 31a of the connector housing body 31 and the board Sb. Spaces are formed. The size a of the gap is equal to the downward protrusion amount L3 of the protrusion 42 with the bottom surface 31a of the connector housing body 31 as the reference plane P2. That is, by providing the protrusion 42 as described above on the connector housing body 31, a gap can be formed between the bottom surface 31a of the connector housing body 31 and the substrate Sb. The size a of this gap is larger than the distance b between the press-fitting portions 59 and 61 of the two adjacent female contacts 50. By setting the dimension a in this way, as described above, it is difficult for a short circuit between adjacent female contacts to occur.

  Therefore, the female connector 3 can provide a connector having a configuration capable of preventing a short circuit between adjacent terminals.

  Further, according to the male connector 2, referring to FIG. 2, the plurality of male contacts 20 in the connector having the plurality of male contacts 20 having different protruding lengths L1 and L2 have the same shape and the same size. The male contact 20 described above, that is, one type of male contact 20 can be used.

  Therefore, according to the male connector 2, the male contact 20 used for manufacturing a connector having male terminals having different protruding lengths with respect to a predetermined portion of the connector housing can be shared.

  Further, in the present embodiment, referring to FIG. 11, the cutting portion 76 is formed in the connecting portion 54. For example, when this cut portion is formed in either one of the press-fitting portions 59 and 61 (that is, when the carrier of the hoop material is connected to the portion corresponding to the press-fitting portion of the female contact portion 74), the following is performed. Problems can occur. Specifically, when thread-shaped burrs, so-called whisker burrs, are produced by cutting between the carrier and the female contact portion, the press-fitting portion is separated from the female terminal next to the female terminal having the press-fitting portion and the partition wall. Since they are adjacent to each other, the distance to the adjacent female terminal is very short. Then, the whisker burr easily contacts the adjacent female contact, and a short circuit between the female contacts easily occurs.

  In this regard, the cutting portion 76 of the female contact 50 of the female connector 3 is formed in the connecting portion 54. Since the connecting portion 54 is relatively distant from the female contact 50 adjacent to the female contact 50 having the connecting portion 54, even if a whisker burr is generated in the connecting portion 54, it is difficult to contact the adjacent female contact 50.

  Therefore, according to the female connector 3, a short circuit between the adjacent female contacts 50 can be prevented.

  In addition, in the hoop material 70 of the present embodiment, with reference to FIGS. 11 and 12, a connecting portion 73 connects the strip-shaped portion 72 and the connecting portion 54. For example, when the connecting portion of the hoop material connects the strip portion and the press-fitting portion, the following problems may occur. Specifically, when a thread-shaped burr, so-called whisker burr, is generated by cutting the connecting portion, the press-fitting portion is adjacent to the female contact adjacent to the female contact having the press-fitting portion with a partition wall therebetween. Therefore, it is very close to the adjacent female contact. Then, the whisker burr easily contacts the adjacent female contact, and a short circuit between the female contacts easily occurs.

  In this respect, the connecting portion 73 of the hoop member 70 connects the strip-shaped portion 72 and the connecting portion 54. Since the connecting portion 54 is relatively distant from the female contact 50 adjacent to the female contact 50 having the connecting portion 54, even if a whisker burr is generated in the connecting portion 54, it is difficult to contact the adjacent female contact 50.

  Therefore, the hoop material 70 can prevent a short circuit between adjacent terminals.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications can be made without departing from the spirit of the present invention.

It has male contact part 94, and these are formed integrally. The male contact portion 94 is provided as a portion of the hoop material 90 that forms the male contact 20.

  In the hoop material 90, the male contact portion 94 is separated from the carrier 91 by cutting the cutting target line 95 which is a boundary between the connecting portion 93 and the male contact portion 94. Thereby, the male contact 20 is formed. In the male contact 20 of the above-described embodiment, the cutting portion 96 generated by cutting the cutting target line 95 is formed in the center portion in the front-rear direction at the upper end of the base portion 21.

  As described above, in the above-described embodiment, with reference to FIGS. 5 and 14A, the cutting target line 95 is formed in the center portion in the front-rear direction at the upper end of the base portion 21 of the male contact 20, but the present invention is not limited to this. .. In this modification, the cut target lines 95a and 95b are provided between the connecting portion 93a and the lead portions 23a and 23b.

  The hoop material 90a of the present modified example has a carrier 91a having a strip portion 92 and a connecting portion 93a, and a male contact portion 94 connected to each connecting portion 93a, and these are integrally formed. The male contact portion 94 is provided as a portion forming the male contacts 20a and 20b in the hoop material 90a.

  In the present modification, two cutting target lines 95a and 95b are provided between the connecting portion 93a and the lead portions 23a and 23b. The cutting target line 95b is formed closer to the carrier 91a than the cutting target line 95a.

  With the hoop material 90a according to this modification, two types of male contacts 20a and 20b can be formed. Specifically, if the male contact portion 94 is cut along the cutting target line 95a, the long male contact 20a having the long lead portion 23a can be formed. A cutting portion 96a formed by cutting the wire 95a to be cut is provided at the tip (upper end) of the long lead portion 23a. On the other hand, if the male contact portion 94 is cut along the cutting target line 95b, the short male contact 20b having the short lead portion 23b can be formed. A cutting portion 96b formed by cutting the cutting target wire 95b is provided at the tip (upper end) of the short lead portion 23b. The long lead portion 23a is longer than the short lead portion 23b.

  The configuration of the long male contact 20a is the same as that of the male contact 20 of the above-described embodiment except that the position of the line to be cut is different and the length of the lead portion is different. Is omitted. Further, the configuration of the short male contact 20b is the same as that of the male contact 20 of the above-mentioned embodiment except that the position of the line to be cut is different, and therefore the description of the configuration is omitted.

  FIG. 16 is a front view of the male connector 2a according to the modification. In the male connector 2a according to the present modification, for the first, fourth, fifth, sixth, seventh, and tenth male contacts from the right, the male contact 20b having the shorter lead portion is used. For the second, third, eighth, and ninth male contacts, the male contact 20a having the longer lead portion is used. In the male connector 2a, the protrusion length L1 of the male contact 20a is the same as the protrusion length L1 of the first contact 25 in the above embodiment, and the protrusion length L2 of the male contact 20b is the second contact in the above embodiment. It is the same as the protruding length L2 of 26.

  On the other hand, in the male connector 2a, unlike the case of the connector 2 of the above-described embodiment, the upward protrusion lengths L4 of the male contacts 20a and 20b with the upper surface 11b of the connector housing body 11 as the reference plane P3 are mutually different. Is the same. This makes it possible to align the protruding lengths of the lead portions of the male contacts 20a and 20b from the substrate Sb when the male connector 2a is set on the substrate Sa. Then, the amount of solder for reliably soldering the male contacts 20a and 20b to the substrate Sa can be made constant, so that the quality of the male connector 2a can be stabilized.

  Moreover, according to this modification, it is possible to form two types of male contacts 20a and 20b having different lead lengths from one type of hoop material 90. That is, according to this modification, it is not necessary to form the hoop material corresponding to each of the two types of male contacts 20a and 20b, and the type of hoop material that needs to be managed can be reduced, so that the product management cost is reduced. it can.

  (2) FIG. 17A is a perspective view of a part of the female connector 3a according to the modification as viewed from below. A plurality of ribs 31b are formed on the bottom surface 31a of the female connector housing 30a of the female connector 3a according to this modification. Each rib 31b is provided corresponding to each partition wall 37, and is provided so as to project downward from the bottom surface of each partition wall 37. Each rib 31b is formed as a ridge extending in the front-rear direction. That is, each rib 31b is provided so as to partition between adjacent female contacts.

  According to the above configuration, even when the liquid solder tries to flow to the adjacent female connector side when soldering the female contact 50 to the substrate, the flow is prevented by the rib 31b. As a result, it is possible to more reliably prevent a short circuit between the adjacent female contacts 50.

  (3) FIG. 17B is a perspective view of a part of the female connector 3b according to the modification as viewed from below. In the female connector 3 according to the above-mentioned embodiment, the reinforcing tab 48 is provided in the female connector housing 30 to secure the fixing strength of the female connector 3 to the substrate Sb. However, the present invention is not limited to this, and FIG. As shown, a boss 45 may be provided on the tip surface of the protruding portion 42 of the female connector housing 30b. The boss 45 is inserted into a boss hole (not shown) formed in the substrate Sb. Thereby, the female connector 3b may be aligned with the substrate Sb.

  (4) FIG. 18A is a perspective view of a part of the female connector 3c according to the modification as viewed from below. 18 (B) is a perspective view of the female contact 50a shown in FIG. 18 (A). The female contact 50a of this modification has substantially the same configuration as the female contact 50 of the above embodiment. However, the female contact 50a is different from the female contact 50 of the above-described embodiment in the configuration of the right side base portion (opposite lead portion side press-fitting portion). In the following, parts different in configuration from the above embodiment will be described, and description of other parts will be omitted.

  With reference to FIG. 18B, a recess 59b is formed in the right-side base portion 52a (opposite lead portion side press-fitting portion 59a). The recess 59b is formed so as to be recessed upward from the lower end portion of the non-lead portion side press-fitting portion 59a. The recess 59b is formed so as to extend in the left-right direction when viewed from the right side. The recessed portion 59b is formed in the left base portion 53 (lead portion side press-fitting portion 61) at a location corresponding to the location where the lead portion 58 is formed.

  According to the female contact 50a having the above configuration, it is possible to more reliably prevent a short circuit between the female contacts 50a adjacent to each other. Specifically, referring to FIG. 18A, when the lead portion 58 is soldered to the substrate, even if liquid solder travels along the direction indicated by the solid arrow in FIG. 18A. Since the recess 59b is formed in the non-lead portion side press-fitting portion 59a of the adjacent female contact 50a, it is difficult for liquid solder to reach the adjacent female contact 50a. Thereby, according to the female contact 50a, a short circuit between the female contacts 50a adjacent to each other can be more reliably prevented.
