2. Background Art
U.S. Pat. No. 7,485,008 discloses a conventional connector including a insulating body, a first terminal group, a second terminal group, and a cable.
At least one of the first and second terminal groups includes a pair of signal terminals and a pair of power terminals. The signal terminals are used to transmit and receive signals, and the power terminals are used to supply power. The signal terminals and the power terminals are connected to core wires of the cable.
The above connector is demanded to supply power with a pair of or a plurality of pairs of power terminals. In other words, the connector is demanded to supply power in a single electrical system or a plurality of systems. However, the connector with a plurality of pairs of power terminals should require space for connection between the power terminal and the core wire (connection object) of the cable in accordance with the number of the power terminals and the core wires, resulting in the upsizing of the connector.
In view of the above-mentioned circumstances, the invention is devised to provide a connector with reduced space for connection between the terminals and the connection objects.

Subsequently, the protruding part 120 of the body 100 is inserted into the tube 510a of the shield case 500a, and the cup 520a of the shield case 500a is placed over the base 110 of the body 100. At this stage, the cable holder 530a of the shield case 500a contacts the insulator 420 of the cable 400. The claws 321 of the lock pieces 300 are received in the respective openings 511a of the tube 510a.
Then, the insulating tape 700 is placed on the body 100 to close the first and second recesses 130a and 130b. After that, the engaging pieces 512a of the tube 510a is inserted into and brought into engagement with the slit 511b of the tongue 510b of the shield case 500b. Simultaneously, the cup 520b of the shield case 500b is placed over the cup 520a to engage the engaging pieces 521a of the cup 520a with the respective engaging holes 521b of the cup 520b. Also, the cup 520b contacts the insulating tape 700, and the cable holder 530b contacts the insulator 420 of the cable 400. The shield cases 500a and 500b are thus combined to cover the body 100. After that, the cable holder 530b is curved like a ring to hold the cable 400 and the cable holder 530a. The shield cases 500a and 500b thus hold the cable 400.
Subsequently, the base 110 of the body 100, the cup 520a of the shield case 500a, the cable holder 530a, the shield case 500b, and the lengthwise end of the cable 400 are placed into a die. Into the die, insulating resin is injected to mold the case 600. The case 600 thus covers the base 110 of the body 100, the cup 520a of the shield case 500a, the cable holder 530a, the shield case 500b, and the lengthwise end of the cable 400.
The connector P described above has at least the following technical features. First, the connector P will not be substantially upsized in accordance with the increase in outer diameter of the first and second core wires 410a and 410b for the purpose of supplying a large amount of power. This is realized through the following arrangement. The second connecting portion 240b is provided in the first bottom 131a and the first side wall 132a of the first recess 130a, and the first connecting portion 240a is provided on the second portion 242b of the second connecting portion 240b. The fourth connecting portion 240d is provided in the second bottom 131b and the second side wall 132b of the second recess 130b, and the third connecting portion 240c is provided on the second portion 242d of the fourth connecting portion 240d. The first core wire 410a is connected to the first and second connecting portions 240a and 240b together in the first recess 130a. The second core wire 410b is connected to the third and fourth connecting portions 240c and 240d together in the second recess 130b. This arrangement can reduce connection spaces (soldering spaces) for connecting between the first core wire 410a and the first and second connecting portions 240a and 240b and for connecting between the second core wire 410b and the third and fourth connecting portions 240c and 240d.
Second, the connector P has improved reliability of connection between the first core wire 410a and the first and second terminals 200a and 200b for the reasons below. The first portion 241b of the second connecting portion 240b is provided in the first side wall 132a of the first recess 130a, and the second portion 242b of the second connecting portion 240b is provided in the first bottom 131a of the first recess 130a. The second portion 242b is in contact with the first connecting portion 240a. The first connecting portion 240a has smaller outer dimensions than the second portion 242b, so that the second portion 242b is partially exposed outside the first connecting portion 240a. This arrangement can increase the area for connection between the first core wire 410a and the first and second connecting portions 240a and 240b. Therefore, connecting the first core wire 410a to at least one of the first and second connecting portions 240a and 240b will result in connection to both the connecting portions. Similarly, the connector P has an improved reliability of connection between the second core wire 410b and the third and fourth terminals 200c and 200d for the reasons below. The first portion 241d of the fourth connecting portion 240d is provided in the second side wall 132b of the second recess 130b, and the second portion 242d of the fourth connecting portion 240d is provided in the second bottom 131b of the second recess 130b. The second portion 242d is in contact with the third connecting portion 240c. The third connecting portion 240c has smaller outer dimensions than the second portion 242d, so that the second portion 242d is partially exposed outside the third connecting portion 240c. This arrangement can increase the area for connection between the second core wire 410b and the third and fourth connecting portions 240c and 240d. Therefore, connecting t the second core wire 410b to at least one of the third and fourth connecting portions 240c and 240d will result in connection to both the connecting portions.
Third, the connector P has an improved reliability of connection with respect to a mating connector R (to be described) for the reasons below. The first and third contact portions 210a and 210c of the first and third terminals 200a and 200c are respectively received in the grooves 152a and 152c in the bottom of the connection part 140. The second contact portion 210b of the second terminal 200b is disposed along the wall on the X1-direction side of the housing recess 154b of the connection part 140. The fourth contact portion 210d of the fourth terminal 200d is disposed along the wall on the X2-direction side of the housing recess 154d of the connection part 140. This means that the first and third contact portions 210a and 210c, and the second and fourth contact portions 210b and 210d are exposed from different places of the connection part 140. Therefore, even if the connector P is pried with its connection hole engaged with the mating connector R, it is still possible to maintain the electrical connection of the mating connector R to at least one of the first and second contact portions 210a and 210b and to at least one of the third and fourth contact portions 210c and 210d.
Fourth, the connector P can be readily modified and therefore has improved versatility. One of the first and second terminals 200a and 200b can be omitted because the first core wire 410a is still connected to the other of the first and second terminals 200a and 200b in the first recess 130a. One of the third and fourth terminals 200c and 200d can be omitted because the second core wire 410b is still connected to the other of the third and fourth terminals 200c and 200d in the second recess 130b. It is thus easy to modify the connector P, simply by omitting one of the first and second terminals 200a and 200b and one of the third and fourth terminals 200c and 200d.
The mating connector R in accordance with an embodiment of the invention will be described below with reference to

The mating connector R may be assembled in the following manner. First, the body 10, the signal terminals 20a, 20b, 20d, and 20e and the ground terminal 20c are prepared. The signal terminals 20a, 20b, 20d, and 20e, particularly the contact portions 21a, 21b, 21d, and 21e and the engaging portions 22a, 22b, 22d, and 22e, are respectively inserted into the engaging holes 14a1, 14b1, 14d1, and 14e1 of the body 10 from the Y2′ direction. The inserted engaging portions 22a, 22b, 22d, and 22e are engaged with the engaging holes 14a1, 14b1, 14d1, and 14e1, respectively. Also, the contact portion 21a, 21b, 21d, 21e are received in the housing grooves 14a2, 14b2, 14d2, and 14e2 of the second protruding part 13 of the body 10, and the contact portions 21a, 21b, 21d, and 21e are exposed from the housing grooves 14a2, 14b2, 14d2, and 14e2, respectively, in the Z2′ direction. The L-shaped portions 23a and 23e of the signal terminals 20a and 20e are respectively received in the housing grooves 14a3 and 14e3 of the body 10, and the hanging portions 23b and 23d of the signal terminals 20b and 20d are respectively received in the housing grooves 14b3 and 14d3 of the body 10.
Similarly, the contact portion 21c and the engaging portion 22c of the ground terminal 20c are inserted into the engaging hole 14c1 of the body 10 from the Y2′ direction. The inserted engaging portion 22c is engaged with the engaging hole 14c1. Also, the contact portion 21c is received in the housing groove 14c2 of the second protruding part 13 of the body 10, and the contact portion 21c is exposed from the housing groove 14c3 in the Z2′ direction. The hanging portion 23c of the ground terminal 20c is received in the housing groove 14c3 of the body 10. The ground terminal 20c is thus disposed between the signal terminal 20b and the signal terminal 20d.
The first to fourth power terminals 30a to 30d are also prepared. The first to fourth power terminals 30a to 30d, particularly the first to fourth contact portions 32a to 32d and the first to fourth arms 31a to 31d, are respectively inserted into the housing portion body 15a2 to 15d2 of the body 10. Simultaneously, the first to fourth engaging portions 34a to 34d of the first to fourth power terminals 30a to 30d are respectively engaged with the engaging hole 15a1 to 15d1 of the body 10. Then, the first and third contact portions 32a and 32c protrude in the Z2′ direction from the housing portion bodies 15a2 and 15c2 (the Z2′-direction end face of the first protruding part 12). The second contact portion 32b protrudes in the X1′ direction from the housing portion body 15b2 (the X1′-direction end face of the first protruding part 12). The fourth contact portion 32d protrudes in the X2′ direction from the housing portion body 15d2 (the X2′-direction end face of the first protruding part 12). The first and third hanging portions 33a and 33c of the first and third power terminals 30a and 30c are housed in the housing grooves 15a3 and 15c3 of the body 10. The second and fourth L-shaped portions 33b and 33d of the second and fourth power terminals 30b and 30d are respectively housed in the housing grooves 15b3 and 15d3 of the body 10. As a result, the first hanging portion 33a is disposed between the L-shaped portion 23a and the hanging portion 23b, and the first tail portion 35a is disposed between the tail portion 24a and the tail portion 24b. The third hanging portion 33c is disposed between the L-shaped portion 23e and the hanging portion 23d, and the third tail portion 35c is disposed between the tail portion 24e and the tail portion 24d. The first to fourth tail portions 35a to 35d and the tail portions 24a to 24e are aligned at intervals in the X1′-X2′ direction such that their lower surfaces are flush with each other
The shield case 40 is also prepared. Into the front space of the shell 41 of the shield case 40 inserted are the first and second protruding parts 12 and 13 of the body 10 to house the base 11 of the body 10 in the rear space of the shell 41. The base 11 then abuts on the shell 41. This is how the mating connector R may be assembled.
The assembled mating connector R may be connected to the connector P in the following manner. The tube 510a and the protruding part 120 of the connector P are fitted into the front space of the shell 41 of the mating connector R. On the other hand, the first and second protruding parts 12 and 13 of the mating connector R are fitted into the connection hole of the connector P. Then, the first contact portion 32a of the first power terminal 30a of the mating connector R elastically contacts the third contact portion 210c of the third terminal 200c of the connector P. The second contact portion 32b of the second power terminal 30b of the mating connector R elastically contacts the fourth contact portion 210d of the fourth terminal 200d of the connector P. The third contact portion 32c of the third power terminal 30c of the mating connector R elastically contacts the first contact portion 210a of the first terminal 200a of the connector P. The fourth contact portion 32d of the fourth power terminal 30d of the mating connector R elastically contacts the second contact portion 210b of the second terminal 200b of the connector P. The claws 321 of the lock pieces 300 of the connector P are engaged with engaging holes in the top plate of the shell 41.
The mating connector R has at least the following technical features. First, the mating connector R realizes power supply to electronic equipment through two electrical systems by way of the first and second power terminals 30a and 30b and the third and fourth power terminals 30c and 30d.
Second, he mating connector R has improved connection reliability for the reasons below. The first and second contact portions 32a and 32b of the first and second power terminals 30a and 30b are exposed from different places of the first protruding part 12, and the third and fourth contact portions 32c and 32d of the third and fourth power terminals 30c and 30d are exposed from different places of the first protruding part 12. In this arrangement, even if the connector P as fitting in the front space of the connector P is pried, it is still possible to maintain the electrical connection of at least one of the first and second contact portions 32a and 32b to at least one of the third and fourth contact portions 210c and 210d of the third and fourth terminals 200c and 200d of the connector P, and the electrical connection of at least one of the third and fourth contact portions 32c and 32d to at least one of the first and second contact portions 210a and 210b of the first and second terminals 200a and 200b of the connector P.
Third, the mating connector R is connectable to a different type of plug connector with contacts that are contactable with the contact portions 21a and 21b of the signal terminals 20a and 20b, the contact portion 21c of the ground terminal 20e, and the contact portions 21d and 21e of the signal terminals 20d and 20e but not contactable with the first to fourth power terminals 30a to 30d. This is made possible by the arrangement of contacts of the mating connector R. Particularly, the contact portions 21a and 21b of the signal terminals 20a and 20b, the contact portion 21c of the ground terminal 20c, and the contact portions 21d and 21e of the signal terminals 20d and 20e are exposed from the surface on the Z2′-direction side of the second protruding part 13. The first and third contact portions 32a and 32c of the first and third power terminals 30a and 30c protrude in the Z2′ direction from the Z2′-direction end face of the first protruding part 12. The second and fourth contact portions 32b and 32d of the second and fourth power terminals 30b and 30d protrude from the X1′- and X2′-direction end faces of the first protruding part 12.
