Description

[Technical field]

[0001] The present invention relates to a board-mounted connector that has a structure in which terminals are press-fitted into a housing and is to be mounted on a circuit board, and to a board with connector in which the connector is mounted on a circuit board. [Background technology]

[0002] Conventionally, a board-mounted connector has been proposed in which a terminal is press-fitted into a press-fit hole provided in a housing, one end of the terminal is used as a contact point (a so-called tab) with a mating terminal, and the other end of the terminal is used as a contact point with a conductor pattern on a circuit board (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-187953 A Summary of the Invention [Problem to be solved by the invention]

[0004] In general, in a board-mounted connector, a plurality of terminals are press-fitted into a plurality of press-fit holes provided in a housing, and each of the plurality of terminals is adapted to electrically connect a mating terminal and a conductor pattern of a circuit board. In order to meet the demands for a smaller and thinner connector, a large number of terminals may be densely arranged in a small housing. On the other hand, excessively reducing the distance between adjacent terminals (so-called insulation distance) is not preferable from the viewpoint of ensuring sufficient insulation between the terminals. In this way, it is generally difficult to achieve both a smaller and thinner connector and the insulation between the plurality of terminals.

[0005] One object of the present invention is to provide a board-mounted connector that can achieve both a small size and low profile of the connector and maintenance of insulation between multiple terminals, and a board with a connector that uses said connector. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the present invention provides a board-mounted connector and a board with a connector, comprising the following features [1] to [ 4 ] is one of its features. [1] A board-mounted connector comprising a housing and a plurality of terminals press-fitted into the housing, the board-mounted connector being to be mounted on a circuit board, The housing includes: a plurality of first press-fit holes arranged along a predetermined arrangement direction, a plurality of second press-fit holes arranged along the arrangement direction at positions different from the positions of the plurality of first press-fit holes in a terminal stage direction intersecting the arrangement direction, and a partition wall portion protruding from the housing and extending along the arrangement direction so as to separate the plurality of first press-fit holes and the plurality of second press-fit holes, Each of the plurality of terminals is a first terminal portion to be press-fitted into the first press-fit hole or the second press-fit hole and to be conductively connected to a mating terminal, and a second terminal portion to be conductively connected to a conductor pattern of the circuit board, The terminal is press-fitted into at least one of the first press-fit holes, The terminal is press-fitted into at least one of the second press-fit holes, In a fitting direction of the housing with a mating housing, the partition wall portion has a flat plate shape that protrudes from the housing in the opposite direction to a position on the opposite side of an opening end of each of the first press-fit hole and the second press-fit hole on a side opposite to a fitting progress direction of the housing in the fitting direction and extends in the arrangement direction. 、 The housing includes: The terminal section further includes an auxiliary wall portion protruding from the partition wall portion in the terminal section direction. It is a board-mounted connector. [ 2 ] [1] To In the connector described, The first terminal portion is a first contact point that contacts the mating terminal to be electrically connected, and a press-fit point that is press-fitted into the first press-fit hole or the second press-fit hole, The second terminal portion is a curved portion extending from the first terminal portion and curved about a curved axis along the axis of the first terminal portion, and a second contact portion that is offset from the first contact portion in a direction intersecting the axis of the first terminal portion and that is electrically connected to the conductor pattern. It is a board-mounted connector. [ 3 ] the above[ 2 In the connector according to the present invention, The second terminal portion is The connector has an upright portion extending from the first terminal portion, passing through the curved portion and extending along the intersecting direction, a first portion extending from an end of the upright portion in a direction along the axis, and a second portion extending from an end of the first portion toward the second contact portion. It is a board-mounted connector. [ 4 ] A circuit board and the above-mentioned [1] to [ 3 and a connector-equipped substrate comprising the connector according to any one of the above items, The circuit board includes: The circuit board has a side edge having a recessed portion that is recessed in a direction along the board surface, The connector includes: the housing is disposed so as to be fitted into the notch portion, and the second terminal portion of the terminal is conductively connected to a conductor pattern of the circuit board, and the terminal is mounted on the circuit board. It is a board with a connector.

[0007] According to the board-mounted connector having the configuration of [1], a partition wall portion is provided between the first and second press-fit holes provided in the housing, protruding from the housing and extending along the arrangement direction so as to separate the press-fit holes from each other. Therefore, compared to the case where the partition wall portion is not provided, the insulation distance (particularly the creepage distance) between the terminals press-fitted into the first and second press-fit holes can be increased. Furthermore, since the partition wall portion has a shape extending along the arrangement direction, the first and second press-fit holes can be separated collectively. Therefore, compared to the case where multiple independent walls are provided between each of the first and second press-fit holes, it is possible to easily form a thin partition wall portion when molding the housing with a mold or the like. In this way, the partition wall portion can increase the insulation distance between the terminals, and the thickness of the partition wall portion itself can also be made thin. Therefore, the board-mounted connector having this configuration can achieve both a small size and low profile of the connector and the maintenance of insulation between the multiple terminals.

[0008] Furthermore, the above[ 1 According to a board-mounted connector having the above configuration, an auxiliary wall portion protruding from the partition wall portion in the terminal stage direction is further provided on the housing. The auxiliary wall portion supports the partition wall portion, so that unintended deformation (e.g., collapse) of the partition wall portion is suppressed even if the thickness of the partition wall portion is made thin. If the auxiliary wall portion is disposed between adjacent first press-fit holes, the insulation distance between the terminals press-fitted into the first press-fit holes can be increased. The same applies to the case where the auxiliary wall portion is disposed between adjacent second press-fit holes.

[0009] the above[ 2According to the board-mounted connector having the configuration of [1], the second terminal portion having the second contact point to be conductively connected to the conductor pattern of the circuit board extends from the first terminal portion having the first contact point to be conductively connected to the mating terminal and has a curved portion that is curved around a curved axis along the axis of the first terminal portion. The terminal has a shape in which the first contact point with the mating terminal and the second contact point with the conductor pattern of the circuit board are offset from each other. For example, when the terminal has a typical crank shape, a preform having a first terminal portion and a second terminal portion (for example, see the chain terminal shown in FIG. 8) is manufactured by punching a metal sheet, and then the preform is bent once at the curved portion so that the first contact point and the second contact point are offset in a predetermined direction. That is, the number of times that the terminal is bent can be reduced compared to the number of times (at least two times) when the terminal is simply formed into a crank shape. In addition, when the terminal has a more complicated shape, for example, a preform having such a shape may be manufactured at the punching stage, or an additional bending process may be performed after the bending process into the crank shape described above. In either case, the number of bending processes can be reduced as described above.

[0010] the above[ 3 According to a board-mounted connector having the configuration of [1], the second terminal portion of the terminal has an upright portion extending from the first terminal portion, passing through a curved portion and extending along the intersecting direction, a first portion extending from an end of the upright portion in a direction along the axis, and a second portion extending from an end of the first portion toward the second contact portion. As a result, even when a circuit board is disposed at a position offset from the first terminal portion in the intersecting direction (see, for example, FIG. 4), the number of bends during the manufacture of the terminal can be reduced as described above, and the terminal can be connected to the conductor pattern of the circuit board.

[0011] the above[ 4According to the connector-attached board having the configuration of [1], the terminals press-fitted into the housing are connected to the conductor pattern of the circuit board in a state in which the connector housing is fitted into the concave cutout of the circuit board. This makes it possible to reduce the overall height of the connector-attached board compared to a case in which the connector is mounted by placing it on the board surface of the circuit board. Effect of the Invention

[0012] Thus, according to the present invention, it is possible to provide a board-mounted connector that is capable of achieving both a small size and low profile connector while maintaining insulation between multiple terminals, and a board with a connector that uses such a connector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] <Embodiment> Hereinafter, a board-mounted connector 1 and a board with connector 7 according to an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, the connector 1 includes a housing 2 and a plurality of terminals 3 press-fitted into the housing 2, and is mounted on a circuit board 4 for use. Through this mounting, a board with connector 7 is manufactured.

[0016] For the sake of convenience, the following definitions are used for the "front-rear direction", "left-right direction", "up-down direction", "front", "rear", "left", "right", "up" and "down" as shown in Figs. 1 to 10. The "front-rear direction", "left-right direction" and "up-down direction" are mutually perpendicular. The front-rear direction coincides with the mating direction of the connector 1 and the mating connector (not shown), and the front side in the mating direction in which the mating connector is mated is defined as the front side, and the rear side in the mating direction opposite thereto is defined as the rear side. The left-right direction coincides with the arrangement direction in which a plurality of upper press-fit holes 33A and a plurality of lower press-fit holes 33B (see Fig. 5, etc.) of the housing 2, which will be described later, are arranged. Hereinafter, each member constituting the connector 1 will be described in order.

[0017] First, the terminal 3 will be described. As shown in Fig. 5 etc., the connector 1 includes, as the multiple terminals 3, multiple upper terminals 3A to be press-fitted into the upper press-fit holes 33A and multiple lower terminals 3B to be press-fitted into the lower press-fit holes 33B. Hereinafter, first, the upper terminals 3A will be described.

[0018] The upper terminal 3A shown in Fig. 6 is formed by bending curved portions 17, 20, and 22 (see Fig. 6) of a preform 3g (see Fig. 8) obtained by punching and pressing a flat metal sheet. The preform 3g has a first terminal portion 11 extending linearly and a second terminal portion 12 extending substantially in an L-shape. The cross section perpendicular to the extension direction of each of the first terminal portion 11 and the second terminal portion 12 is rectangular.

[0019] 6, the first terminal portion 11 has a shape that extends linearly in the front-rear direction as a whole. The front end portion of the first terminal portion 11 functions as a first contact point 13 that comes into contact with a mating terminal (female terminal, not shown) accommodated in a mating connector to establish an electrical connection. A pair of press-fitting projections 14 that project in both the left and right directions are provided at two positions in the front-rear direction on the rear side of the first contact point 13 of the first terminal portion 11.

[0020] The first terminal portion 11 has a wide portion 15 protruding further in both left and right directions from the pair of press-fit projections 14 at a position rearward of the press-fit projections 14. The wide portion 15 functions as a stopper that determines the front-rear position of the upper terminal 3A relative to the housing 2 when the upper terminal 3A is press-fitted. The rear end face (a rectangular plane perpendicular to the front-rear direction) of the first terminal portion 11 functions as a pressing surface 16 against which a press-fit jig (not shown) is pressed when the upper terminal 3A is press-fitted. Therefore, the press-fit jig can be pressed against the pressing surface 16 located on an extension of the axis of the first contact point 13, so that the structure of the terminal 3 can be simplified compared to a case in which a dedicated pressing surface (for example, a so-called shoulder portion) is separately provided on the terminal 3. Furthermore, defects such as buckling are unlikely to occur in the first terminal portion 11 when the upper terminal 3A is press-fitted.

[0021] As shown in FIG. 6, the second terminal portion 12 includes a curved portion 17 extending from the rear end of the first terminal portion 11 (the portion rearward of the wide portion 15) toward the right and curved upward, an erected portion 18 extending upward from the upper end of the curved portion 17, a first portion 19 extending rearward from the upper end of the erected portion 18, a curved portion 20 extending rearward from the rear end of the first portion 19 and curved downward, a second portion 21 extending downward from the lower end of the curved portion 20, a curved portion 22 extending downward from the lower end of the second portion 21 and curved rearward, and a second contact portion 23 extending rearward from the rear end of the curved portion 22. The second contact portion 23 is electrically connected to the conductor pattern 42A of the circuit board 4 (see FIGS. 4 and 5). The curved portion 17 is curved around a curved axis X offset parallel to the right side from the axis of the first terminal portion 11.

[0022] Thus, in the upper terminal 3A, the second terminal portion 12 is offset to the right with respect to the first terminal portion 11 (see FIG. 6(a)). Also, the second contact point 23 is offset downward with respect to the first contact point 13 (see FIG. 6(b)).

[0023] In upper terminal 3A, a crank shape (see FIG. 6(b)) consisting of first terminal portion 11, standing portion 18, and first portion 19 when viewed from the left-right direction can be obtained by performing a single bending process on curved portion 17. Therefore, compared to a general processing method in which a crank shape is obtained by bending two portions in the extension direction of a terminal, the number of bending processes performed on the terminal to obtain the crank shape can be reduced.

[0024] In the upper terminal 3A, the thickness T2 (see FIG. 6(a)) of the second terminal portion 12 is smaller than the thickness T1 (see FIG. 6(b)) of the first terminal portion 11 (see FIG. 8(b) as well). More specifically, the second terminal portion 12 has a shape in which the thickness is reduced in a direction in which the curved outer surface (lower surface in FIG. 8(b)) at the curved portion 17 approaches the curved inner surface (upper surface in FIG. 8(b)), and thus the thickness T2 of the second terminal portion 12 is thinner than the thickness T1 of the first terminal portion 11. This makes it easier to perform bending when providing the curved portion 17 of the second terminal portion 12. Furthermore, in this example, the multiple upper terminals 3A are arranged in the housing 2 in a state of being lined up in the left-right direction (see FIG. 4, etc.). In this case, between the upper terminals 3A adjacent in the left-right direction, the curved portion 17 of the left upper terminal 3A and the left end face of the rear end of the first terminal portion 11 of the right upper terminal 3A are closest in the left-right direction (see FIG. 9(b)). In this regard, the plate thickness T2 (i.e., the thickness in the left-right direction) of the curved portion 17 (= a part of the second terminal portion 12) is reduced in the direction away from the adjacent first terminal portion 11, so that the left-right distance Y between them (so-called insulation distance) can be increased.

[0025] In the upper terminal 3A, the front-to-rear width T3 (see FIG. 6(b)) of the curved portions 17 and the standing portions 18 is greater than the plate thicknesses T1 and T2. This increases the rigidity of the curved portions 17, and the shape of the upper terminal 3A after bending of the curved portions 17 is properly maintained. As a result, the coplanarity (flatness) of the second contact points 23 of the multiple upper terminals 3A is improved, improving the reliability of the electrical connection between the circuit board 4 and the connector 1. The upper terminal 3A has been described above.

[0026] The upper terminal 3A described above is manufactured, for example, as follows. First, a metal sheet is punched to obtain a chained terminal in which a plurality of preforms 3g are connected by a carrier 5, as shown in FIG. 8(a). Next, for the chained terminal, press processing is sequentially performed on only the second terminal portion 12 of each preform 3g, so that the plate thickness T2 of the second terminal portion 12 of each preform 3g is made smaller than the plate thickness T1 of the first terminal portion 11 (see also FIG. 8(b)). Next, in the chained terminal, the carrier 5 is removed to separate the plurality of preforms 3g from each other, and each preform 3g is bent at its curved portions 17, 20, 22 (see FIG. 6). In this way, a plurality of upper terminals 3A are obtained. Note that bending of some or all of the curved portions 17, 20, 22 (see FIG. 6) may be performed before or after the upper terminal 3A is press-fitted into the housing 2.

[0027] As can be understood from the above-mentioned manufacturing procedure, in the second contact point 23 of the upper terminal 3A, the punched surface (cut surface) generated when punching the thin metal plate faces and is connected to the conductor patterns 42A, 42B of the circuit board 4. From the viewpoint of achieving good electrical connection, in this example, the punched surface of the second contact point 23 is plated. An example of the plating material is gold (Au). Note that, in general, gold plating is provided on an undercoat plating of copper, nickel, or the like provided on a base material. Note that a similar plating may be applied not only to the punched surface of the second contact point 23 but also to the entire punched surface of the upper terminal 3A. In this example, a similar plating is also applied to the second contact point 23 of the lower terminal 3B described later.

[0028] Next, the lower terminal 3B will be described. Regarding the lower terminal 3B shown in FIG. 7, the same or equivalent configurations as those of the upper terminal 3A shown in FIG. 6 are denoted by the same reference numerals as those of the upper terminal 3A, and the description thereof will not be repeated. The second contact point 23 of the lower terminal 3B is conductively connected to the conductor pattern 42B of the circuit board 4 (see FIGS. 4 and 5). The lower terminal 3B is also manufactured from a chain terminal as shown in FIG. 8 through the same process as the upper terminal 3A. The lower terminal 3B also achieves the same various functions and effects as those described above for the upper terminal 3A. Below, the main differences between the lower terminal 3B and the upper terminal 3A will be described.

[0029] In the lower terminal 3B, contrary to the upper terminal 3A, the curved portion 17 extends leftward from the rear end of the first terminal portion 11 (see FIG. 7(a)). That is, the curved portion 17 is curved around a curved axis X that is offset in parallel to the left side from the axis of the first terminal portion 11. Therefore, in the upper terminal 3A, the second terminal portion 12 is offset rightward from the first terminal portion 11 (see FIG. 6(a)), whereas in the lower terminal 3B, the second terminal portion 12 is offset leftward from the first terminal portion 11 (see FIG. 7(a)).

[0030] In the lower terminal 3B, the overall shape of the second terminal portion 12 is different from that of the upper terminal 3A. Therefore, in the upper terminal 3A, the second contact point 23 is offset downward from the first contact point 13 (see FIG. 6(b)), whereas in the lower terminal 3B, the second contact point 23 is offset upward from the first contact point 13 (see FIG. 7(b)). As a result, when the upper terminal 3A and the lower terminal 3B are press-fitted into the upper press-fit hole 33A and the lower press-fit hole 33B of the housing 2, respectively, the second contact point 23 of the upper terminal 3A and the second contact point 23 of the lower terminal 3B are positioned on the same plane (see FIG. 4, etc.). The lower terminal 3B has been described above.

[0031] Next, the housing 2 will be described. The housing 2 is a resin molded product, and includes a rectangular tubular main body 31 that extends in the front-rear direction and is long in the left-right direction, as shown in Fig. 2 etc. The rear end of the main body 31 is closed by a rectangular flat rear end wall 32 (see Figs. 4 and 5), while the front end of the main body 31 is open. When the connector 1 is mated with the mating connector, the mating connector is inserted and mated into the internal space of the main body 31 through the front end opening of the main body 31, and the mated state is maintained by a locking portion 31a provided in the left-right central portion of the upper wall of the main body 31.

[0032] 3(c), 5, etc., a plurality of upper-stage press-fit holes 33A are provided in the rear end wall 32 so as to be aligned in the left-right direction, and a plurality of lower-stage press-fit holes 33B are provided in the rear end wall 32 so as to be aligned in the left-right direction below the plurality of upper-stage press-fit holes 33A. Each of the upper-stage press-fit holes 33A and the lower-stage press-fit holes 33B is a through hole having a rectangular cross section and penetrating in the front-rear direction.

[0033] The first terminal portion 11 of the upper terminal 3A is inserted and press-fitted into the upper press-fit hole 33A from the rear. This press-fitting is performed by pressing the first terminal portion 11 forward with a press-fitting tool (not shown) pressed against the pressing surface 16. This press-fitting progresses while the press-fitting protrusion 14 of the first terminal portion 11 rubs against the inner wall surface of the upper press-fit hole 33A, and is completed when the wide portion 15 of the first terminal portion 11 abuts against the rear end edge of the upper press-fit hole 33A. Similarly, the first terminal portion 11 of the lower terminal 3B is inserted and press-fitted into the lower press-fit hole 33B from the rear.

[0034] As shown in FIG. 4, in the press-fitted state, the first contact points 13 of the first terminal portions 11 of the upper terminal 3A and the lower terminal 3B are located in the internal space of the main body 31, and the second terminal portions 12 of the upper terminal 3A and the lower terminal 3B extend rearward from the rear end wall 32 of the main body 31, and the second contact points 23 are exposed to the outside of the main body 31. The second contact points 23 of the upper terminals 3A are arranged side by side in the left-right direction, and the second contact points 23 of the lower terminals 3B are arranged side by side in the left-right direction in front of the second contact points 23. All the second contact points 23 of the upper terminals 3A and the lower terminals 3B are located on the same plane. The second contact points 23 of the upper terminals 3A are connected to the conductor pattern 42A of the circuit board 4, and the second contact points 23 of the lower terminals 3B are connected to the conductor pattern 42B of the circuit board 4.

[0035] The left-right spacing (pitch) between adjacent upper-stage press-fit holes 33A is the same as the left-right spacing (pitch) between adjacent lower-stage press-fit holes 33B. In this example, as can be seen from Fig. 3(b), the upper-stage press-fit holes 33A are arranged to be shifted to the left by half a pitch relative to the lower-stage press-fit holes 33B. In other words, the upper-stage press-fit holes 33A and the lower-stage press-fit holes 33B are arranged in a positional relationship (so-called zigzag or staggered) in which they do not overlap each other in the up-down direction when viewed from the front-rear direction.

[0036] Therefore, the first terminal portion 11 of the lower terminal 3B1 (see FIG. 3(b) and FIG. 10) pressed into the lower press-fit hole 33B located at the rightmost position among the plurality of lower press-fit holes 33B is located to the right of the first terminal portion 11 of the upper terminal 3A pressed into the upper press-fit hole 33A located at the rightmost position among the plurality of upper press-fit holes 33A. Conversely, the first terminal portion 11 of the upper terminal 3A1 (see FIG. 3(b) and FIG. 10) pressed into the upper press-fit hole 33A located at the leftmost position among the plurality of upper press-fit holes 33A is located to the left of the first terminal portion 11 of the lower terminal 3B pressed into the lower press-fit hole 33B located at the leftmost position among the plurality of lower press-fit holes 33B. In this example, in order to avoid interference with the lock portion 31a, the upper press-fit hole 33A is not provided in the center region in the left-right direction (see FIG. 3(b)). This can further promote the reduction in height of the main body portion 31.

[0037] Furthermore, for each of the upper terminal 3A and the lower terminal 3B, the offset amount in the left-right direction between the first terminal portion 11 and the second terminal portion 12 coincides with the half pitch. Therefore, as shown in Fig. 10, for the lower terminal 3B in which the first terminal portion 11 is press-fitted into the lower press-fit hole 33B, and the upper terminal 3A in which the first terminal portion 11 is press-fitted into the upper press-fit hole 33A located half a pitch to the left of the lower press-fit hole 33B, the position of the second terminal portion 12 of the upper terminal 3A coincides with the position of the first terminal portion 11 of the lower terminal 3B in the left-right direction, and the position of the first terminal portion 11 of the upper terminal 3A coincides with the position of the second terminal portion 12 of the lower terminal 3B.

[0038] 5 and other figures, the rear end wall 32 is provided with a plate-like partition wall portion 34 that protrudes rearward and extends in the left-right direction between the upper press-fit holes 33A and the lower press-fit holes 33B in the vertical direction so as to separate the upper press-fit holes 33A and the lower press-fit holes 33B from each other. In this example, the upper surface of the partition wall portion 34 is flush with and continuous with the lower end edges of the inner walls of the upper press-fit holes 33A. By providing the partition wall portion 34 in this way, it is possible to increase the insulation distance (particularly the creepage distance) between the upper terminal 3A press-fitted into the upper press-fit hole 33A and the lower terminal 3B press-fitted into the lower press-fit hole 33B, compared to the case where the partition wall portion 34 is not provided.

[0039] The lower surface of the partition wall portion 34 is provided with auxiliary wall portions 35 protruding downward at left-right positions corresponding to the lower press-fit holes 33B (see Figs. 5 and 10, etc.). In other words, each auxiliary wall portion 35 is provided between adjacent upper press-fit holes 33A in the left-right direction (see Fig. 10). As a result, the auxiliary wall portions 35 support the partition wall portion 34, so that even if the thickness of the partition wall portion 34 is made thin, the partition wall portion 34 is prevented from collapsing. Furthermore, since the second terminal portion 12 (particularly the first portion 19) of each lower terminal 3B is located in the space between adjacent auxiliary wall portions 35 (see Fig. 10), the insulation distance between adjacent lower terminals 3B is increased. The direction in which the auxiliary wall portions 35 extend (vertical direction) is also referred to as the terminal stage direction.

[0040] 2 and other figures, a pair of overhanging portions 36 are provided in the upper regions of the left and right sides of the main body 31 so as to protrude in the left-right direction and extend in the front-rear direction. The pair of overhanging portions 36 function as stoppers that determine the vertical position of the housing 2 with respect to the circuit board 4 when the housing 2 is mounted on the circuit board 4. Each overhanging portion 36 is provided with a peg attachment portion 37, and a metal peg 6 is attached and fixed to each peg attachment portion 37.

[0041] The main body 31 is provided with a pair of protective walls 38 that are continuous with the pair of overhanging portions 36 and further protrude rearward. As a result, the pair of protective walls 38 are arranged to sandwich the second terminal portions 12 of the upper terminals 3A and the lower terminals 3B extending rearward from the upper press-fit holes 33A and the lower press-fit holes 33B in the left-right direction, and function to protect the second terminal portions 12 of the upper terminals 3A and the lower terminals 3B. As shown in Figs. 2 and 10, a pair of engagement protrusions 39 that protrude downward is provided on the lower surface of the pair of protective walls 38. The pair of engagement protrusions 39 are inserted into a pair of positioning holes 44 (see Fig. 2) of the circuit board 4.

[0042] 10, in this example, for a lower terminal 3B1 in which a first terminal portion 11 is press-fitted into a lower press-fit hole 33B located at the rightmost position among the plurality of upper press-fit holes 33A and lower press-fit holes 33B, the second terminal portion 12 is located to the left of the first terminal portion 11 (i.e., inside in the left-right direction). Similarly, for an upper terminal 3A1 in which a first terminal portion 11 is press-fitted into an upper press-fit hole 33A located at the leftmost position among the plurality of upper press-fit holes 33A and lower press-fit holes 33B, the second terminal portion 12 is located to the right of the first terminal portion 11 (i.e., inside in the left-right direction). This makes it easier to ensure a large distance L1 between the second terminal portion 12 of the lower terminal 3B1 and the right protective wall portion 38, and a large distance L2 between the second terminal portion 12 of the upper terminal 3A1 and the left protective wall portion 38.

[0043] In other words, in both the upper press-fit hole 33A and the lower press-fit hole 33B, the first terminal portion 11 of the terminal 3 can be disposed as far outward as possible in the left-right direction, while the second terminal portion 12 of the terminal 3 can be disposed at a position away from the pair of protective wall portions 38. Therefore, since there is no need to design the pair of protective wall portions 38 to be moved outward in the left-right direction to avoid contact with the second terminal portion 12, the size of the housing 2 in the arrangement direction (i.e., the left-right direction) can be reduced. The housing 2 has been described above.

[0044] Next, the circuit board 4 will be described. The resin circuit board 4 has a rectangular flat plate shape with a rectangular cutout 41 formed in an area excluding both left and right ends of the front end face, as shown in Fig. 2. The cutout 41 has a shape corresponding to the outer shape of the main body 31 of the housing 2 (the shape viewed from the top and bottom direction).

[0045] On the upper surface of the rear region of the cutout portion 41 of the circuit board 4, a plurality of conductor patterns 42A are arranged in the left-right direction in correspondence with the second contact points 23 of the plurality of upper terminals 3A, and a plurality of conductor patterns 42B are arranged in the left-right direction at front positions of the plurality of conductor patterns 42A in correspondence with the second contact points 23 of the plurality of lower terminals 3B.

[0046] A pair of recesses 43 are provided on the upper surface of the circuit board 4 in the left-right outer region of the cutout portion 41, corresponding to the pair of pegs 6 fixed to the housing 2. The pair of pegs 6 are received in and soldered to the pair of recesses 43. A pair of positioning holes (through holes) 44 are provided on the upper surface of the circuit board 4 in the left-right outer region of the plurality of conductor patterns 42A, 42B. The circuit board 4 has been described above.

[0047] In order to mount the connector 1 on the circuit board 4, first, the housing 2 is placed above the circuit board 4, as shown in Fig. 2. Next, the main body 31 of the housing 2 is inserted so as to fit into the cutout portion 41 of the circuit board 4, the pair of pegs 6 are housed in the pair of recesses 43, and the pair of engagement protrusions 39 are inserted into the pair of positioning holes 44, and the housing 2 and the circuit board 4 are brought closer to each other in the vertical direction until the lower surfaces of the pair of projections 36 abut against the circuit board 4 so that the second contact points 23 of the plurality of upper terminals 3A contact the plurality of conductor patterns 42A, respectively, and the second contact points 23 of the plurality of lower terminals 3B contact the plurality of conductor patterns 42B, respectively (see Fig. 1).

[0048] Next, the pair of pegs 6 accommodated in the pair of recesses 43 are adhered and fixed to the pair of recesses 43 by adhesive or solder, and the second contact points 23 of the plurality of upper terminals 3A are fixed to the plurality of conductor patterns 42A by solder, and the second contact points 23 of the plurality of lower terminals 3B are fixed to the plurality of conductor patterns 42B by solder. This completes the mounting of the housing 2 on the circuit board 4. By mounting the connector 1 so as to fit into the notches 41 provided in the circuit board 4 in this manner, the overall structure of the connector 1 and the circuit board 4 can be made lower in height than when the connector 1 is mounted by placing it on the board surface of the circuit board 4.

[0049] <Actions and Effects> As described above, according to the board-mounted connector 1 of the present embodiment, the partition wall portion 34 is provided between the upper press-fit holes 33A and the lower press-fit holes 33B provided in the housing 2, so as to separate the press-fit holes 33A and 33B from each other, protruding from the housing 2 and extending along the left-right direction (arrangement direction). Therefore, compared to the case where the partition wall portion 34 is not provided, it is possible to increase the insulation distance (particularly the creepage distance) between the upper terminal 3A and the lower terminal 3B pressed into the upper press-fit hole 33A and the lower press-fit hole 33B. Furthermore, since the partition wall portion 34 has a shape extending along the left-right direction of the circuit board 4 so as to collectively separate the upper press-fit holes 33A and the lower press-fit holes 33B, it is possible to easily form a thin partition wall portion 34 when forming the housing with a mold or the like, compared to the case where multiple independent walls are provided between each of the upper press-fit holes 33A and each of the lower press-fit holes 33B. Therefore, the board-mounted connector 1 according to this embodiment can achieve both a small size and a low profile of the connector 1 and the maintenance of insulation between the multiple terminals 3A, 3B.

[0050] Furthermore, an auxiliary wall portion 35 is further provided protruding from the partition wall portion 34 in the vertical direction (terminal stage direction). The auxiliary wall portion 35 supports the partition wall portion 34, so that even if the thickness of the partition wall portion 34 is made thin, the partition wall portion 34 is prevented from collapsing. Furthermore, if the auxiliary wall portion 35 is disposed between the adjacent upper stage press-fitting holes 33A, the insulation distance between the upper stage terminals 3A pressed into the upper stage press-fitting holes 33A can be increased. The same is true even when the auxiliary wall portion 35 is disposed between the adjacent lower stage press-fitting holes 33B. Therefore, the board-mounted connector 1 according to this embodiment can further contribute to achieving both a smaller size and lower height of the connector 1 and maintaining insulation between the multiple terminals 3A and 3B.

[0051] Furthermore, the terminal 3 is configured such that the second terminal portion 12 having the second contact portion 23 to be conductively connected to the conductor patterns 42A, 42B of the circuit board 4 extends from the first terminal portion 11 having the first contact portion 13 to be conductively connected to the mating terminal and has a curved portion 17 that is curved around a curved axis along the axis of the first terminal portion 11. For example, when the terminal 3 has a typical crank shape, the terminal 3 can be manufactured by punching out a preform (see, for example, FIG. 8) having the first terminal portion 11 and the second terminal portion 12 from a metal sheet, and then performing a single bending process so that the first terminal portion 11 and the second terminal portion 12 are offset in the thickness direction of the circuit board 4. That is, the number of times bending processes are performed on the terminal 3 can be reduced.

[0052] Furthermore, the second terminal portion 12 has an upright portion 18 extending from the first terminal portion 11, passing through a curved portion 17 and extending along the intersecting direction, a first portion 19 extending from an end portion of the upright portion 18 in a direction along the axis, and a second portion 21 extending from an end portion of the first portion 19 toward a second contact portion 23. As a result, even when the circuit board 4 is disposed at a position offset from the first terminal portion 11 in the intersecting direction, the number of times the terminal 3 is bent during manufacture can be reduced as described above, and the terminal 3 can be connected to the conductor patterns 42A, 42B of the circuit board 4.

[0053] Furthermore, with the housing 2 of the connector 1 positioned to fit into the cutout 41 of the circuit board 4, the terminals 3 press-fitted into the housing 2 are connected to the conductor patterns 42A, 42B of the circuit board 4. This allows the connector-equipped board 7 to have a lower overall height than when the connector 1 is placed on the board surface of the circuit board 4.
