Background Art

[0002] Conventionally, as an internal circuit of an electrical connection box for an automobile, a connector mounting substrate in which a connector is mounted on a printed board has been used. In the connector mounting substrate, a connector housing constituting the connector is fixed to the printed board by screwing. By the way, in recent years, in response to the requirements for space saving and weight reduction, instead of screwing, a connector device has been proposed in which a connector housing is fixed to a printed board by a metal peg (Patent Document 1).

[0003] However, in the above-described connector device, the connector housing may be lifted (tilted) by the stress along the connection direction applied at the time of connection of the mating connector, and the soldering between the peg and the substrate may be peeled off. Therefore, the connector device of Patent Document 1 provides a hook that hooks the substrate to the mating connector in order to prevent the tilting of the connector housing. However, providing the hook increases the size of the mating connector, and there is a problem that care is required during transportation because there is a concern about breakage of the hook.

[0012] Hereinafter, for convenience of explanation, as shown in FIGS. 1 to 6, "front (F)", "rear (B)", "left (L)", "right (R)", "up (U)" and "down (D)" are defined. The "front-rear direction", the "left-right direction" and the "up-down direction" are orthogonal to each other. The front-rear direction corresponds to the "connection direction" of the present invention, and the rear side corresponds to the "mating connector side in the connection direction" of the present invention.

[0013] As shown in Figure 1, the connector mounting board 1 of this embodiment can be connected to two mating connectors 10. As shown in Figure 2, the connector mounting board 1 comprises a board 2, a connector 3 mounted on the upper surface of the board 2, and a housing case 4 that houses the board 2.

[0014] The substrate 2 is made of a flat plate made of synthetic resin and is rectangular in shape when viewed from above. The substrate 2 is arranged so that its thickness is aligned with the vertical direction. As shown in Figure 3, the substrate 2 is provided with through-holes 21 that penetrate vertically through the substrate, through which signal terminals 51 and power terminals 52 (described later) are inserted, and through-holes 22 that penetrate vertically through the substrate, through which pegs 7 (described later) are inserted. The substrate 2 is also provided with terminal connection parts 23 and foot connection parts 24. These terminal connection parts 23 and foot connection parts 24 are formed by printing a conductive material such as metal onto the surface of the substrate 2.

[0015] The terminal connection section 23 is where the signal terminal 51 and power terminal 52 are soldered and connected. The terminal connection section 23 is provided along the edge of the through-hole 21 on the upper surface of the circuit board 2. The foot connection section 24 is where the feet 72 of the peg 7 are soldered and connected. The foot connection section 24 is provided along the edge of the through-hole 22 on the upper surface of the circuit board 2.

[0016] Next, the connector 3 will be described. In this embodiment, as shown in Figure 2, two connectors 3 are arranged side by side on the circuit board 2 in the left-right direction. As shown in Figure 4, the connector 3 has signal terminals 51 and power terminals 52 connected to the circuit board 2, a connector housing 6 that holds these signal terminals 51 and power terminals 52, and four pegs 7 for fixing the connector housing 6 to the circuit board 2.

[0017] The signal terminal 51 and power terminal 52 are arranged in a roughly L-shape and have a mating connector connection portion 501 that runs in the front-to-back direction and a board connection portion 502 that hangs downward from the front end of the mating connector connection portion 501. The mating connector connection portion 501 is inserted through the terminal retaining hole 611 of the connector housing 6, and the part behind the terminal retaining hole 611 is connected to the mating terminal 11 (see Figure 6) provided on the mating connector 10. The lower end of the board connection portion 502 is inserted through the through hole 21 and protrudes from the lower surface of the board 2. The board connection portion 502 is connected to a terminal connection portion 23 provided on the upper surface of the board 2 by soldering.

[0018] The connector housing 6 is made of a synthetic resin such as PCB (Poly Chlorinated Biphenyl). As shown in Figure 4, the connector housing 6 includes a terminal holding portion 61 which is erected above the substrate 2 and has terminal holding holes 611 for inserting and holding the signal terminals 51 and power terminals 52, and a pair of attitude holding portions 62, 62 which extend from the terminal holding portion 61 along the substrate 2 on both sides in the front-rear direction.

[0019] In this embodiment, the connector housing 6 consists of a terminal holding portion 61 and a pair of attitude holding portions 62, 62, and the entire mating connector connection portion 501 that protrudes rearward from the terminal holding portion 61 is exposed from the connector housing 6. In other words, the connector housing 6 is not provided with a housing portion for accommodating and mating the mating connector 10.

[0020] The terminal holding section 61 is provided in the shape of a plate perpendicular to the front-to-back direction. The terminal holding section 61 is provided with multiple terminal holding holes 611 through which signal terminals 51 and power terminals 52 are inserted and held. In this embodiment, multiple terminal holding holes 611 for signal terminals 51 are provided in both the upper and lower sections, arranged in a row along the left-to-right direction (seven in this embodiment). In addition, two terminal holding holes 611 for power terminals 52 are provided, arranged in a left-to-right direction, flanking the terminal holding holes 611 for signal terminals 51.

[0021] The pair of attitude-holding parts 62, 62 are provided extending from both the left and right ends of the terminal holding part 61 in the front and rear directions, with their lower surfaces overlapping the substrate 2. The pair of attitude-holding parts 62, 62 are provided in a plate shape perpendicular to the left and right directions, with their upper surfaces positioned below the terminal holding holes 611. As shown in Figure 5, the front ends of the pair of attitude-holding parts 62, 62 extend to a position in front of the substrate connection parts 502 of the signal terminals 51 and power terminals 52. The rear ends of the pair of attitude-holding parts 62, 62 extend to the same position in the front and rear direction as, or slightly behind, the tip of the mating connector connection part 501 of the signal terminals 51 and power terminals 52.

[0022] Furthermore, as shown in Figure 4, the pair of posture-holding parts 62, 62 are provided with peg-holding holes 621 on their outer surfaces for holding pegs 7. As shown in Figure 5, two peg-holding holes 621 are provided side by side in the front-to-back direction for each posture-holding part 62, and each posture-holding part 62 holds two pegs 7. One of the two pegs 7, 7 is held in the same position as the terminal-holding part 61 in the posture-holding part 62, and the other of the two pegs 7, 7 is held at a position closer to the end (rear side) than the center between the rear end of the posture-holding part 62 and one of the pegs 7. The pair of peg-holding holes 621 are provided penetrating the posture-holding part 62 in the vertical direction. In this embodiment, the peg-holding holes 621 have openings 622 on the left-to-right outer side. The openings 622 extend along the vertical direction, and it is possible to visually confirm whether a peg 7 is inserted through the openings 622.

[0023] Next, the structure of the peg 7 will be described. The peg 7 is formed by punching out a metal plate. As shown in Figure 3, the peg 7 has a retained portion 71 and a single foot portion 72. The retained portion 71 is wider in the front-to-back direction than the foot portion 72 and is press-fitted into the peg retaining hole 621. The foot portion 72 is provided protruding from the lower end of the retained portion 71 toward the base plate 2 and is inserted through a through-hole 22 provided in the base plate 2. The foot portion 72 is provided in a straight shape along the vertical direction and does not have any bends or other features.

[0024] Next, the configuration of the storage case 4 will be described. As shown in Figures 2 and 6, the storage case 4 comprises a roughly box-shaped case body 8 with an open front and a lid 9 that closes the front opening of the case body 8. The case body 8 comprises a bottom wall 81, a left side wall 82, a right side wall 83, a top wall 84, a rear side wall 85, a first partition wall 86, and a pair of second partition walls 87, 87. The bottom wall 81 is provided in a rectangular shape that covers the lower side of the substrate 2. The left side wall 82 is provided erected upward from the left end of the bottom wall 81. The right side wall 83 is provided erected upward from the right end of the bottom wall 81. The rear and upper corners of the right side wall 83 are cut out, and the vertical height of the front side is set higher than the vertical height of the rear side. The upper wall 84 covers the upper side of the substrate 2 and extends from the upper end of the left wall 82 to the upper end of the right wall 83 in front of the notch.

[0025] The rear wall 85 is erected from the rear end of the bottom wall 81. The right and upper corners of the rear wall 85 are cut out, and the vertical height on the left side is set higher than the vertical height on the right side. The left side portion of the rear wall 85, which is higher in the vertical direction, extends from the rear end of the bottom wall 81 to the rear end of the top wall 84. The first partition wall 86 is erected from the upper end of the right side portion of the rear wall 85, which is lower in the vertical direction, toward the front. As shown in Figure 6, the first partition wall 86 is positioned above the attitude holding portion 62 and extends toward the front of the tip of the mating connector connection portion 501. As shown in Figure 2, the pair of second partition walls 87, 87 are erected above the first partition wall 86 and are arranged side by side in the left-right direction.

[0026] Specifically, the housing case 4 has a cylindrical housing section 88 formed by the second partition wall 87 on the left, the upper wall 84, the second partition wall 87 on the right, and the first partition wall 86, with the rear open and a portion of the front opening closed by the terminal holding portion 61 of the connector 3 on the left.

[0027] The mating housing 12 of the mating connector 10 is housed in these two housing sections 88, 88. When the mating housing 12 is housed in the housing section 88, the mating terminals 11, signal terminals 51, and power terminals 52 are connected, as shown in Figure 6. In addition, a locking arm 841 is provided on the upper wall 84, which can lock with a locking projection 13 provided on the mating housing 12 of the mating connector 10.

[0028] According to the embodiment described above, since one attitude-holding part 62 is connected to the substrate 2 by two independent pegs 7, the fixing strength of the connector 3 can be increased. Furthermore, one of the two pegs 7 is fixed to the attitude-holding part 62 that is rearward of the terminal-holding part 61. As a result, when connecting to the mating connector 10, a force (shown by a thick arrow) is applied to the front end of the attitude-holding part 62, with the front end acting as a fulcrum P (Figure 6), causing the connector 3 to tilt, but the peg 7 can be placed at a location far from the fulcrum P. Therefore, the tilting of the connector 3 can be suppressed with a small force, and solder cracks can be suppressed. In other words, the tilting of the connector 3 can be suppressed without providing a tilt prevention structure on the mating connector 10.

[0029] According to the embodiment described above, the connector housing 6 is provided such that the signal terminals 51 and power terminals 52 are exposed on the rear side of the terminal holding portion 61. That is, the connector housing 6 does not have a cylindrical housing portion for accommodating the mating connector 10. As a result, the connector housing 6 is shaped in such a way that the terminal holding portion 61 is supported by the attitude holding portion 62 that protrudes on both the front and rear sides, allowing it to be stably fixed to the substrate 2.

[0030] According to the embodiment described above, the other of the two pegs 7 is held at a position closer to the end (rear side) than the midpoint between the rear end of the posture-holding portion 62 and one of the pegs 7. This allows the other peg 7 to be positioned even further away from the pivot point P where the force that causes the connector 3 to tip over is applied.

[0031] According to the embodiment described above, the housing case 4 can be provided with a cylindrical housing portion 88 in which the mating connector 10 is housed.

[0032] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.

[0033] In the above-described embodiment, two pegs 7 were held in one posture-holding section 62, but this is not the only case. A single posture-holding section 62 may hold multiple pegs 7, or it may hold three or more pegs 7.

[0034] According to the embodiment described above, the housing case 4 is provided with a housing section 88, but this is not the only option. The connector housing 6 may also be provided with a housing section 88.
