BACKGROUND OF THE INVENTION
This invention relates to a connector mateable with a mating connector, and to an electronic equipment comprising the connector.
Referring to FIGS. 24 and 25, JPA2017-21899 (Patent Document 1) discloses a connector 900. Specifically, the connector 900 is configured to be mounted on a circuit board 980 and is mateable with a mating connector (not shown) along an X-direction. The circuit board 980 has pads 982, 986. The pad 982 is positioned in a negative X-direction beyond the pad 986. The connector 900 comprises a mating portion 905, a holding member 910 and terminals 950. Specifically, the holding member 910 has a plate-like portion 912, and each of the terminals 950 has a substantially L-like shape. When the connector 900 is mounted on the circuit board 980, the mating portion 905 protrudes beyond a positive X-end of the circuit board 980. The terminals 950 are grouped into two groups including a group of upper terminals 960 and a group of lower terminals 970. Each of the upper terminals 960 has a contact portion 962 and a surface mount technology (SMT) portion 966. The contact portion 962 is arranged on an upper surface 9122 of the plate-like portion 912. The SMT portion 966 is soldered on the pad 982 of the circuit board 980 when the connector 900 is mounted on the circuit board 980. Each of the lower terminals 970 has a contact portion 972 and an SMT portion 976. The contact portion 972 is arranged on a lower surface 9126 of the plate-like portion 912. The SMT portion 976 is soldered on the pad 986 of the circuit board 980 when the connector 900 is mounted on the circuit board 980. When the connector 900 mounted on the circuit board 980 is viewed from its positive Z-side, the SMT portion 976 of the lower terminal 970, which is soldered on the pad 986, is invisible because the upper terminal 960 hides the SMT portion 976. Similarly, when the connector 900 mounted on the circuit board 980 is viewed from its negative X-side, the SMT portion 976 of the lower terminal 970, which is soldered on the pad 986, is invisible because the upper terminal 960 hides the SMT portion 976.
When the soldering operation is done in a state where the connector 900 simply rests on the circuit board 980 so that the mating portion 905 protrudes beyond the positive X-end of the circuit board 980, the connector 900 is tilted relative to the circuit board 980 by the weight of the mating portion 905. This makes difficult to solder the SMT portion 966, 976 of the connector 900 on the pad 982, 986 of the circuit board 980 in a state where the connector 900 rests on the circuit board 980, and this might cause the SMT portion 966, 976 to be poorly soldered on the pad 982, 986.
In addition, the SMT portion 976 of the lower terminal 970, which is soldered on the pad 986 of the circuit board 980, is hidden by the upper terminal 960 as described above. Accordingly, if the SMT portion 976 of the lower terminal 970 is poorly soldered on the pad 986, it is a difficult matter to resolder the SMT portion 976 on the pad 986. Specifically, if the SMT portion 976 of the lower terminal 970 is poorly soldered on the pad 986, the circuit board 980, on which the connector 900 is mounted, itself must be discarded as defective. This increases the manufacturing costs of the connector 900 and the circuit board 980.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a connector which enables its SMT portion to be easily soldered on a circuit board and which enables its SMT portion to be resoldered on a circuit board if the SMT portion is poorly soldered on the circuit board.
One aspect (first aspect) of the present invention provides a connector mateable with a mating connector along a front-rear direction. The mating connector comprises a plurality of mating terminals. The connector comprises a first sub connector and a second sub connector. The first sub connector and the second sub connector are mateable with each other in a direction intersecting with the front-rear direction. The first sub connector comprises a first holding member and a plurality of first terminals. The first holding member has at least a plate-like portion. The plate-like portion has an upper surface and a lower surface. The first terminals are brought into contact with the mating terminals, respectively, when the connector and the mating connector are mated with each other. The first terminals include a plurality of upper terminals and a plurality of lower terminals. Each of the upper terminals has an upper contact portion, an upper extending portion and a first upper contact point. The upper contact portion extends in the front-rear direction and is arranged on the upper surface of the plate-like portion. The upper extending portion extends in a direction intersecting with the front-rear direction. The upper extending portion has an end portion. The first upper contact point is provided at the end portion of the upper extending portion. Each of the lower terminals has a lower contact portion, a lower extending portion and a first lower contact point. The lower contact portion extends in the front-rear direction and is arranged on the lower surface of the plate-like portion. The lower extending portion extends in a direction intersecting with the front-rear direction. The lower extending portion has an end portion. The first lower contact point is provided at the end portion of the lower extending portion. The second sub connector is configured to be mounted on a circuit board. The second sub connector comprises a second holding member and a plurality of second terminals. The second holding member holds the second terminals. The second terminals are arranged in two rows. Each of the second terminals has a second contact point and an SMT portion. The second contact point of the second terminal of one of the two rows is brought into contact with the first upper contact point under a mated state where the first sub connector and the second sub connector are mated with each other. The second contact point of the second terminal of a remaining one of the two rows is brought into contact with the first lower contact point under the mated state where the first sub connector and the second sub connector are mated with each other. The SMT portion is configured to be fixed on the circuit board. The SMT portion of the second terminal of the one of the two rows extends in an orientation opposite to an orientation in which the SMT portion of the second terminal of the remaining one of the two rows extends.
Another aspect (second aspect) of the present invention provides an electronic equipment comprising the connector of the first aspect, the circuit board and a housing. The connector is mounted on the circuit board. The circuit board is attached to an inside of the housing. The housing is provided with a receiving portion which communicates with an outside of the housing. The plate-like portion is positioned in the receiving portion.
The connector of the present invention comprises the first sub connector and the second sub connector. In addition, the first sub connector and the second sub connector are mateable with each other in the direction intersecting with the front-rear direction, and the second sub connector is configured to be mounted on a circuit board. Accordingly, the connector of the present invention is configured so that the whole of the connector can be mounted on a circuit board by the first sub connector being mated with the second sub connector after the mounting of the second sub connector on the circuit board. Thus, in the connector of the present invention, the SMT portion can be easily soldered on a circuit board.
In addition, the second sub connector of the connector of the present invention is configured so that the SMT portion of the second terminal of the one of the two rows extends in the orientation opposite to the orientation in which the SMT portion of the second terminal of the remaining one of the two rows extends. Thus, even without the second sub connector having an increased size in a pitch direction, the connector of the present invention can allow the SMT portion to be easily resoldered on a circuit board when the SMT portion is poorly soldered on the circuit board.
An appreciation of the objectives of the present invention and a more complete understanding of its structure may be had by studying the following description of the preferred embodiment and by referring to the accompanying drawings.

Referring FIG. 19, the second holding member 310 of the present embodiment is made of insulator. The second holding member 310 holds the second terminals 350. The second holding member 310 has an upper terminal accommodating portion 312, a lower terminal accommodating portion 314, and an island-like portion 318.
As shown in FIG. 18, the upper terminal accommodating portion 312 of the present embodiment is a space which is recessed downward in the up-down direction. The upper terminal accommodating portion 312 is positioned rearward of the lower terminal accommodating portion 314 in the front-rear direction. The upper terminal accommodating portion 312 is positioned rearward of the island-like portion 318 in the front-rear direction. As shown in FIG. 5, when the second sub connector 300 is mated with the first sub connector 200, the upper terminal accommodating portion 312 accommodates the first upper contact points 266, the auxiliary first upper contact points 268 and the first upper contact point holding portion 2183 of the first sub connector 200.
As shown in FIG. 18, the lower terminal accommodating portion 314 of the present embodiment is a space which is recessed downward in the up-down direction. As shown in FIG. 5, when the second sub connector 300 is mated with the first sub connector 200, the lower terminal accommodating portion 314 accommodates the first lower contact points 276, the auxiliary first lower contact points 278 and the first lower contact point holding portion 2185 of the first sub connector 200.
As shown in FIG. 18, the island-like portion 318 of the present embodiment protrudes upward in the up-down direction. As shown in FIG. 19, the island-like portion 318 is positioned between the upper terminal accommodating portion 312 and the lower terminal accommodating portion 314 in the front-rear direction. As shown in FIG. 5, when the second sub connector 300 is mated with the first sub connector 200, the island-like portion 318 is accommodated in the island-like portion accommodating portion 2186 of the first sub connector 200.
Referring to FIG. 19, each of the second terminals 350 of the present embodiment is made of conductor. The second terminals 350 are arranged in two rows 360, 370. More specifically, the second terminals 350 of each of the two rows 360, 370 are arranged in the pitch direction. The second terminal 350 of the row 360, i.e. one of the two rows 360, 370, is positioned rearward of the second terminal 350 of the row 370, i.e. a remaining one of the two rows 360, 370, in the front-rear direction. The second terminals 350 of the row 360 correspond to the upper terminals 260, respectively. The second terminals 350 of the remaining row 370 correspond to the lower terminals 270, respectively.
As shown in FIG. 18, each of the second terminals 350 of the present embodiment has a second contact point 352, a surface mount technology (SMT) portion 355 and an auxiliary second contact point 358.
As shown in FIG. 5, the second contact point 352 of the present embodiment is a female contact. When the first sub connector 200 and the second sub connector 300 are mated with each other, the female contact 352 receives the male contact 266 or the male contact 276 and is brought into contact with the male contact 266 or the male contact 276. The second contact point 352 is resiliently displaceable in the front-rear direction.
As shown in FIG. 5, the auxiliary second contact point 358 of the present embodiment is a female contact. When the first sub connector 200 and the second sub connector 300 are mated with each other, the female contact 358 receives the auxiliary first upper contact point 268 or the auxiliary first lower contact point 278 and is brought into contact with the auxiliary first upper contact point 268 or the auxiliary first lower contact point 278. The auxiliary second contact point 358 is resiliently displaceable in the front-rear direction. The auxiliary second contact point 358 is positioned outward of the second contact point 352 in the front-rear direction. The second contact point 352 and the auxiliary second contact point 358 face each other in the front-rear direction. The second contact point 352 and the auxiliary second contact point 358 are positioned at the same position as each other in the pitch direction.
Referring to FIGS. 5 and 16, the second sub connector 300 of the present embodiment is configured so that, when the first sub connector 200 and the second sub connector 300 are mated with each other, the auxiliary second contact point 358 of the second terminal 350 of the row 360 of the two rows 360, 370 rides over the upper step portion 267 and is then brought into contact with the auxiliary first upper contact point 268. Referring to FIGS. 5 and 17, when the first sub connector 200 and the second sub connector 300 are mated with each other, the second contact point 352 of the second terminal 350 of the remaining row 370 of the two rows 360, 370 rides over the lower step portion 277 and is then brought into contact with the first lower contact point 276. Thus, the riding over provides a clicking sensation to a user when the user mates the first sub connector 200 and the second sub connector 300 to each other.
As shown in FIG. 5, the second sub connector 300 of the present embodiment is configured so that the second contact point 352 of the second terminal 350 of the row 360 of the two rows 360, 370 is brought into contact with the first upper contact point 266 under a mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. Specifically, the second contact point 352 of the second terminal 350 of the row 360 is brought into direct contact with the first upper contact point 266 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. As described above, the first upper contact point 266 is the male contact which extends in the direction intersecting with the front-rear direction. Accordingly, the first upper contact point 266 has an effective contact length which is sufficient in the direction intersecting with the front-rear direction. In other words, a part of the first upper contact point 266 that can be brought into contact with the second contact point 352 extends long in the direction intersecting with the front-rear direction. The second contact points 352 of the second terminals 350 of the row 360 may be brought into one-to-one contact with the first upper contact points 266. Additionally, the second contact points 352 of the second terminals 350 of the row 360 may be simultaneously brought into contact with the common first upper contact point 266. The second contact point 352 of the second terminal 350 of the remaining row 370 of the two rows 360, 370 is brought into contact with the first lower contact point 276 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. Specifically, the second contact point 352 of the second terminal 350 of the remaining row 370 is brought into direct contact with the first lower contact point 276 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. As described above, the first lower contact point 276 is the male contact which extends in the direction intersecting with the front-rear direction. Accordingly, the first lower contact point 276 has an effective contact length which is sufficient in the direction intersecting with the front-rear direction. In other words, a part of the first lower contact point 276 that can be brought into contact with the second contact point 352 extends long in the direction intersecting with the front-rear direction. The second contact points 352 of the second terminals 350 of the remaining row 370 may be brought into one-to-one contact with the first lower contact points 276. Additionally, the second contact points 352 of the second terminals 350 of the remaining row 370 may be simultaneously brought into contact with the common first lower contact point 276.
As shown in FIG. 5, the second sub connector 300 of the present embodiment is configured so that the auxiliary second contact point 358 of the second terminal 350 of the row 360 of the two rows 360, 370 is brought into contact with the auxiliary first upper contact point 268 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. Specifically, the auxiliary second contact point 358 of the second terminal 350 of the row 360 is brought into direct contact with the auxiliary first upper contact point 268 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. As described above, the auxiliary first upper contact point 268 is the male contact which extends in the direction intersecting with the front-rear direction. Accordingly, the auxiliary first upper contact point 268 has an effective contact length which is sufficient in the direction intersecting with the front-rear direction. In other words, a part of the auxiliary first upper contact point 268 that can be brought into contact with the auxiliary second contact point 358 extends long in the direction intersecting with the front-rear direction. The auxiliary second contact points 358 of the second terminals 350 of the row 360 may be brought into one-to-one contact with the auxiliary first upper contact points 268. Additionally, the auxiliary second contact points 358 of the second terminals 350 of the row 360 may be simultaneously brought into contact with the common auxiliary first upper contact point 268. The auxiliary second contact point 358 of the second terminal 350 of the remaining row 370 of the two rows 360, 370 is brought into contact with the auxiliary first lower contact point 278 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. Specifically, the auxiliary second contact point 358 of the second terminal 350 of the remaining row 370 is brought into direct contact with the auxiliary first lower contact point 278 under the mated state where the first sub connector 200 and the second sub connector 300 are mated with each other. As described above, the auxiliary first lower contact point 278 is the male contact which extends in the direction intersecting with the front-rear direction. Accordingly, the auxiliary first lower contact point 278 has an effective contact length which is sufficient in the direction intersecting with the front-rear direction. In other words, a part of the auxiliary first lower contact point 278 that can be brought into contact with the auxiliary second contact point 358 extends long in the direction intersecting with the front-rear direction. The auxiliary second contact points 358 of the second terminals 350 of the remaining row 370 may be brought into one-to-one contact with the auxiliary first lower contact points 278. Additionally, the auxiliary second contact points 358 of the second terminals 350 of the remaining row 370 may be simultaneously brought into contact with the common auxiliary first lower contact point 278.
As shown in FIG. 18, the second terminals 350 of the present embodiment are arranged at regular intervals in the pitch direction. An interval between the second terminals 350 of the row 360 may, however, be modified in accordance with a pitch interval between the first upper contact points 266 of the upper terminals 260 corresponding thereto. Similarly, an interval between the second terminals 350 of the remaining row 370 may be modified in accordance with a pitch interval between the first lower contact points 276 of the lower terminals 270 corresponding thereto.
As described above, the first sub connector 200 is configured so that each of the first upper contact points 266 is positioned at the same position as the first lower contact point 276 corresponding thereto in the pitch direction perpendicular to the front-rear direction. More specifically, the first upper contact point 266, the auxiliary first upper contact point 268, the first lower contact point 276 and the auxiliary first lower contact point 278 are positioned at the same position as each other in the pitch direction. Accordingly, in the second sub connector 300 mateable with the first sub connector 200, an arrangement of the second terminals 350 of the row 360 and an arrangement of the second terminals 350 of the remaining row 370 occupy the same extent in the pitch direction. Thus, the second sub connector 300 can have a minimized size in the pitch direction.
As described above, the connector 100 is configured as follows: the first sub connector 200 and the second sub connector 300 are mateable with each other in the direction intersecting with the front-rear direction; each of the first upper contact point 266 and the first lower contact point 276 of the first sub connector 200 has the effective contact length which is sufficient in the direction intersecting with the front-rear direction; and each of the auxiliary first upper contact point 268 and the auxiliary first lower contact point 278 of the first sub connector 200 has the effective contact length which is sufficient in the direction intersecting with the front-rear direction. In other words, the part of each of the first upper contact point 266 and the first lower contact point 276 of the first sub connector 200 that can be brought into contact with the second contact point 352 extends in the direction intersecting with the front-rear direction, and the part of each of the auxiliary first upper contact point 268 and the auxiliary first lower contact point 278 of the first sub connector 200 that can be brought into contact with the auxiliary second contact point 358 extends in the direction intersecting with the front-rear direction. These enable the first sub connector 200 and the second sub connector 300 to be appropriately connected with each other even if the first sub connector 200 and the second sub connector 300 are mated with each other while the first sub connector 200 and the second sub connector 300 are slightly misaligned from each other in the direction intersecting with the front-rear direction. In addition, each of the second contact point 352 and the auxiliary second contact point 358 of the second sub connector 300 is resiliently displaceable in the front-rear direction, and the second contact point 352 and the auxiliary second contact point 358 face each other in the front-rear direction. These enable the first sub connector 200 and the second sub connector 300 to be appropriately connected with each other even if the first sub connector 200 and the second sub connector 300 are mated with each other while the first sub connector 200 and the second sub connector 300 are slightly misaligned from each other in the front-rear direction. Specifically, even in a case where the first sub connector 200 and the second sub connector 300 are mated with each other while the first sub connector 200 is slightly misaligned forward from the second sub connector 300, the auxiliary first lower contact point 278 is brought into contact with the auxiliary second contact point 358 while the first upper contact point 266 is brought into contact with the second contact point 352. Thus, the first sub connector 200 and the second sub connector 300 can be appropriately connected with each other even in this case. Similarly, even in a case where the first sub connector 200 and the second sub connector 300 are mated with each other while the first sub connector 200 is slightly misaligned rearward from the second sub connector 300, the first lower contact point 276 is brought into contact with the second contact point 352 while the auxiliary first upper contact point 268 is brought into contact with the auxiliary second contact point 358. Thus, the first sub connector 200 and the second sub connector 300 can be appropriately connected with each other even in this case.
As shown in FIG. 5, the SMT portion 355 of the present embodiment is configured to be fixed on the circuit board 600. As shown in FIG. 20, the SMT portion 355 of the second terminal 350 of the row 360 extends in an orientation opposite to an orientation in which the SMT portion 355 of the second terminal 350 of the remaining row 370 extends. The direction in which the SMT portion 355 extends is the front-rear direction. More specifically, the SMT portion 355 of the second terminal 350 of the row 360 extends rearward, and the SMT portion 355 of the second terminal 350 of the remaining row 370 extends forward.
Referring to FIG. 19, each of the connected portions 380 of the present embodiment is made of metal. Each of the connected portions 380 faces inward in the front-rear direction. As understood from FIGS. 14 and 19, when the second sub connector 300 is mated with the first sub connector 200, the connected portion 380 is connected with the connecting portion 284 of the midplate 280 of the first sub connector 200.
As shown in FIGS. 2, 3 and 6, the housing 700 of the present embodiment is provided with a receiving portion 710 which communicates with the outside of the housing 700. The receiving portion 710 opens forward in the front-rear direction. The plate-like portion 212 of the first holding member 210 of the first sub connector 200 is positioned in the receiving portion 710. The receiving portion 710 surrounds the plate-like portion 212 in the plane perpendicular to the front-rear direction. A front end of the receiving portion 710 is positioned forward beyond a front end of the plate-like portion 212.
Referring to FIGS. 2 and 6, the housing 700 has a shell 750 and a connecting hole (not shown). The shell 750 is positioned in the receiving portion 710. However, the present invention is not limited thereto. Specifically, the housing 700 may have no shell 750.
The connecting hole of the present embodiment is a hole piercing the receiving portion 710 in the front-rear direction.

A part of the middle portion 214 of the first holding member 210 of the first sub connector 200 is positioned in the connecting hole.
Referring to FIGS. 2 and 6, the shell 750 of the present embodiment is made of conductive member. The shell 750 is arranged on an inner surface of the receiving portion 710. The shell 750 surrounds the plate-like portion 212 in the plane perpendicular to the front-rear direction. Since the housing 700 has the shell 750, electrical noise generated in the first sub connector 200 can be strongly prevented from being emitted.
As shown in FIGS. 2 and 6, the connector 100 of the present embodiment is attached to the housing 700 by the connector 100 being inserted into the connecting hole of the housing 700 from a rear side of the connecting hole. The electronic equipment 400 is provided with an adhesive member (not shown) between the housing 700 and the base portion 216 of the first holding member 210 of the first sub connector 200 of the connector 100. The base portion 216 of the first holding member 210 of the first sub connector 200 is attached to the housing 700 by the adhesive member. In other words, the connector 100 is attached to the housing 700 by the adhesive member. Thus, the electronic equipment 400 can be assembled in the following simpler order: the first sub connector 200 is attached to the housing 700 by the adhesive member; the second sub connector 300 is fixed on the circuit board 600; and the first sub connector 200 and the second sub connector 300 are mated with each other. The aforementioned adhesive member may be, for example, a double-sided tape or an epoxy-based glue. Additionally, the adhesive member may be selected from any kind of materials that can adhere the connector 100 and the housing 700 to each other.
