Description

Technical Field

The present invention belongs to a cable connector for connecting between conductive contacts and wires of a cable.

Background Art

Referring to Figs. 1 and 2, description will be made of a cable connector in a first related technology. The illustrated cable connector comprises a base insulator 114 provided with a plurality of conductive contacts 112 mutually arrayed in two rows, two cover insulators 121, 122 having a long plate shape and sandwiching two cables 117, 118 each arranged with a plurality of wires arrayed in a flat manner at predetermined intervals to each other, to thereby retain them, and a plurality of conductive cable-connection contacts 125 provided on the two cover insulators 121, 122, respectively.
The contact 112 comprises a socket portion 112a adapted to contact with the cable-connection contact 125, and a pin-shaped contact portion 112b adapted to contact with a counterpart contact of a counterpart connector not illustrated. The cable-connection contact 125 comprises a pin-shaped connection contact portion 125a provided between a plurality of grooves 131, 132 formed at one edge portion of each of the two cover insulators 121, 122, and a connection retaining portion 125b driven into each of a plurality of holes 135 formed near the grooves 131, 132.
The base insulator 114 comprises a base portion 114b including a fitting portion 114a that is open and arranged with the contact portions 112b for receiving the counterpart connector (not illustrated) fitted thereinto to bring the counterpart contacts into contact with the contacts 112, and base fixing portions 114c provided on both sides of the base portion 114b. The base fixing portion 114c is formed with a base screw hole 114d. Further, the two cover insulators 121, 122 are each formed with cover screw holes 121a to 121d, 122a to 122d near four corners thereof.
The two cables 117, 118 are sandwiched between the two cover insulators 121, 122. On the upper cover insulator 121, the wires of the upper cable 117 are connected to the upper cable-connection contacts 125 in one-to-one correspondence. On the lower cover insulator 122, the wires of the lower cable 118 are connected to the lower cable-connection contacts 125 in one-to-one correspondence.
Thereafter, the two cover insulators 121, 122 are screwed to each other by engaging screws 141 into the cover screw holes 121a to 121d, 122a to 122d for fixedly sandwiching the cables 117, 118. The two cover screw holes 122b, 122c are matched in position with the base screw holes 114c, 114d and screwed thereto. The two cover insulators 121, 122 are connected to the contacts 112 in the state where they are retained to the base insulator 114.
An example of a cable connector according to the first related technology is also disclosed in Japanese Patent Application Publication (JP-A) No. H10-303529 .
With respect to the cable connector according to the first related technology 1, however, the base insulator 114 and the cover insulators 121, 122 are held by jigs (not illustrated), respectively, and connection is carried out along guides of the jigs, and therefore, reliability upon the connection is poor. Further, the cover insulators 121, 122 and the base insulator 114 are screwed to each other to fix the cover insulators 121, 122, thereby achieving rigidity of the whole cable connector. However, the screwing operation takes much time and, if trying to achieve automation, facilities become complicated, which thus has been a factor of poor economical efficiency.
Referring now to Fig. 3, description will be made of a cable connector according to a second related technology. The illustrated cable connector uses one coaxial flat ribbon-shaped cable 117 like the cable shown in Fig. 1. The cable 117 has an end portion formed as a cable curved portion 117a having a generally S-shaped side and having been subjected to bending. The cable curved portion 117a is fixed by concavo- convex portions 121e, 122e formed by two cover insulators 121, 122.
In this case, operations such as a process of bending the cable 117 and a strip process of stripping the cable 117 of its coating portions to expose wires, are carried out.
Further, referring to Fig. 4, description will be made of a cable connector according to a third related technology. In the illustrated cable connector, two cables 117, 118 like the cables shown in Fig. 1 are overlapped each other via an intermediate member 161. The cables 117, 118 are sandwiched and fixed by two cover insulators 121, 122 as shown in Fig. 1 and the intermediate member 161. The cables 117, 118 are provisionally fixed to the cover insulators 121, 122 using double-coated tapes 165, 166, respectively. The intermediate member 161 serves to prevent coming-off of the cables 117, 118.
Examples of cable connectors according to the second and third related technologies are also disclosed in Japanese Patent Application Publication (JP-A) No. H11-329620 .
With respect to the cable connector according to the second related technology, however, there is a problem that the bent cable 117 is in an unstable state until the cover insulator 121 and the cover insulator 122 are united with each other so that it is difficult to automate the operations.
Further, with respect to the cable connector according to the third related technology, much time is required for the operation of sticking the cables 117, 118 onto the cover insulators 121, 122. Further, upon moving between the operation processes, there are instances where an external force is exerted to the cables 117, 118 to tear off the stuck cables 117, 118.
Further, there is a problem that inasmuch as the intermediate member 161 is provided between the cables 117, 118, it becomes unstable even in case of automatic assembly.
A known cable connector is disclosed in document JP 2000223189 , in which a cable connector is shown that is used for connecting a cable having a plurality of wires. The cable connector comprises a plurality of conductive contacts, a base insulator retaining said contacts, and a cable-side insulator that is attachable/detachable relative to said base insulator, arraying and retaining said wires in one plane, and connecting said wires to said contacts when attached to said base insulator. The base insulator has a base portion arraying said contacts at predetermined intervals to each other, and a pair of base guide portions that extend from both ends of said base portion while confronting each other. The cable-side insulator has a pair of cover guide portions of which movement is guided by said base guide portions.

It is therefore an object of the present invention to provide a cable connector that can improve reliability of connection and ensure rigidity of the whole connector in a connected state.
It is another object of the present invention to provide a cable connector that can achieve automation of production with simple facilities and thus is excellent in economics.
It is still another object of the present invention to provide a cable connector that can reduce operation processes for retaining a cable to shorten an operation time and that can accurately manage the overall length of a cable harness assembly.
It is still another object of the present invention to provide a cable connector that can prevent movement of a cable even when an external force is exerted on the cable, thereby to improve yield upon connection.

Best Mode for Carrying Out the Invention

Referring to Figs. 5 to 9, description will be made of a cable connector according to a first embodiment of the present invention.
The illustrated cable connector comprises a plurality of conductive contacts 11 (see Fig. 7), a base insulator 13 retaining these contacts 11 arrayed in two rows, two cover insulators 26, 27 sandwiching two cables 23, 24 each like a flat ribbon cable formed with a plurality of wires 21 in a flat manner at predetermined intervals to each other, to thereby retain them, and a plurality of conductive cable-connection contacts 28 retained by the cover insulators 26, 27, respectively. The contact 11 comprises a socket portion 11a adapted to contact with the cable-connection contact 28, and a pin-shaped contact portion 11b adapted to contact with a counterpart contact of a counterpart connector not illustrated.
Each of the cover insulators 26, 27 is formed with a plurality of connection grooves 31 at one edge portion thereof, and with a plurality of holes 33 near these connection grooves 31. The cable-connection contact 28 comprises a pin-shaped connection contact portion 28a disposed in the connection groove 31, and a connection retaining portion 28b press-fitted into the hole 33.
The connection contact portion 28a provided on the upper cover insulator 26 is connected with an end portion of the wire 21 of the cable 23 in the state where the end portion enters the connection groove 31 and is wound round therein. The connection contact portion 28a provided on the lower cover insulator 27 is connected with an end portion of the wire 21 of the cable 24 in the state where the end portion enters the connection groove 31 and is wound round therein. The cover insulators 26, 27 conjointly form a cable-side insulator.
The base insulator 13 comprises a base portion 14 extending in an array direction of the contacts 11, and a pair of base guide portions 15 extending in an insert/draw direction perpendicular to the array direction from both ends of the base portion 14 while confronting each other. That is, observing the base insulator 13 in a plan view, a generally ⊐-shape is exhibited by the base portion 14 and the pair of base guide portions 15. Mutually confronting surfaces of the base guide portions 15 are each formed with a long base guide groove 16 extending in the insert/draw direction. The base portion 13 is formed with a fitting portion 18 that is open for receiving the counterpart connector (not illustrated) fitted thereinto. When the counterpart connector is fitted into the fitting portion 18, the counterpart contacts of the counterpart connector are brought into contact with the contacts 11. Incidentally, in the base guide portion 15, a groove width of the base guide groove 16 is formed widest near an entrance portion located apart from the base portion 14 while slightly narrower at a deep portion near the base portion 14. The groove width of the base guide groove 16 will be made clear with later description.
The fitting portion 18 is partitioned into an upper portion and a lower portion by a partition plate 19 integral with the base portion 14. The contact portions 11b of the plurality of contacts 11 are arranged in each of the upper portion and the lower portion of the fitting portion 18. On the side opposite to the fitting portion 18, the socket portions 11a of the contacts 11 are arranged. Specifically, the socket portions 11a are located in the base portion 14 at portions deeper than the pair of base guide portions 15. The contacts 11 in the upper portion and the lower portion are arranged in a symmetrical manner, seen from the partition plate 19.
Connecting portions of the wires 21 connected to the connection contact portions 28a of the cable-connection contacts 28 provided on the upper cover insulator 26 enter the socket portions 11 a of the upper contacts 11 so as to contact therewith. Connecting portions of the wires 21 connected to the connection contact portions 28a of the cable-connection contacts 28 provided on the lower cover insulator 27 enter the socket portions 11 a of the lower contacts 11 so as to contact therewith. In this manner, the cable-connection contacts 28 serve as support contacts for supporting the connection of the cables 23, 24.
The cables 23, 24 are fixed to the cover insulators 26, 27 using double-coated tapes 36 or adhesives, respectively, and confront each other when the cover insulators 26, 27 are mated with each other. The cover insulators 26, 27 are formed in the same shape and size with each other, and come into the state to sandwich the cables 23, 24 therebetween when they are united together with one of them postured to turn round by an angle of 180 degrees. Inasmuch as the cover insulators 26, 27 have the same shape and size with each other, description will be given about the one cover insulator 26, while description about the other cover insulator 27 will be omitted by assigning the same symbols to the respective portions.
The cover insulator 26 comprises a main plate portion 41 of a rectangular shape having a width dimension equal to or slightly smaller than a width dimension between the base guide portions 15, a connection plate portion 43 integrally connected so as to project in a manner slightly descending stepwise relative to the main plate portion 41 at one side perpendicular to the width direction of the main plate portion 41, and a pair of cover guide portions 45 integrally connected so as to project in a manner slightly descending stepwise at both sides in the width direction of the main plate portion 41. In order to receive an end portion of the flat-shaped cable 23, the main plate portion 41 has the width dimension substantially equal to a width dimension of the end portion of the cable 23. The connection plate portion 43 is formed with the connection grooves 31 where the end portions of the wires 21 of the cable 23 enter and are wound round as described before.
The cover guide portions 45 project from the both sides in the width direction of the main plate portion 41. Specifically, the cover guide portions 45 comprise a pair of cover projecting portions 45a projecting outward relative to the main plate portion 41 near the connection plate portion 43, a pair of fixing plate portions 45b projecting largely outward relative to the width dimension of the main plate portion 41 on the side opposite to the connection plate portion 43, and a pair of engaging portions 45c formed in the insert/draw direction between the cover projecting portions 45a and the fixing plate portions 45b.
The pair of engaging portions 45c project and extend in a direction perpendicular to a plate thickness direction of the main plate portion 41 and, given a central point of the plane of the main plate portion 41, they are formed on a diagonal crossing the central point on the plane. That is, when the two cover insulators 26, 27 are combined, the engaging portions 45c of the one cover insulator 26 and the engaging portions 45c of the other cover insulator 27 are engaged with each other in the insert/draw direction. In this event, the fixing plate portions 45b of the one cover insulator 26 and the fixing plate portions 45b of the other cover insulator 27 are mated to each other on the plane parallel to the plane of the main plate portion 41. Further, the connection plate portion 43 of the one cover insulator 26 and the connection plate portion 43 of the other cover insulator 27 confront each other on the planes parallel to the plane of the main plate portion 41 at a predetermined interval therebetween.
The fixing plate portions 45 are formed with two cover through holes 47. Mutually parallel base guide plate portions 15a defining the base guide groove 16 of the base guide portion 15 are formed with base through holes 51 at corresponding positions.
The cover insulators 26, 27 are inserted into the base guide grooves 16 with the connection plate portions 43 facing forward, thereby to be retained by the base insulator 13. In this state, the wires 21 are brought into contact with the contacts 11. In the connected state after having brought the wires 21 into contact with the contacts 11, the base through holes 51 and the cover through holes 47 are located with their axes in a shared state.
In the state where the cover insulators 26, 27 are retained by the base insulator 13, the cover projecting portions 45a enter deep portions of the base guide grooves 16. Further, the fixing plate portions 45b are fitted into the base guide grooves 16 near the entrance side to prevent the cover insulators 26, 27 from being further inserted relative to the base insulator 13.
Referring to Fig. 10, description will be made of an operation after the cover insulators 26, 27 are fully inserted into the base insulator 13.
When the cover insulators 26, 27 are fully inserted into the base insulator 13, the connected state is obtained as described above. Thereafter, pins 53 such as parallel pins or spring pins are driven to be inserted upright into the base through holes 51 and the cover through holes 47. The base insulator 13 is fixed to the cover insulators 26, 27 by the pins 53. In this manner, the cover insulators 26, 27 are prevented from coming off the base insulator 13. Therefore, even if the cables 23, 24 are pulled, the cover insulators 26, 27 do not come off the base insulator 13.
Further, at least either of the base guide portions 15 and the cover guide portions 45 are provided with press-fitted relation giving means for putting the base guide portions 15 and the cover guide portions 45 mutually into a press-fitted relation.
Referring to Figs. 11 to 14, a specific example of the press-fitted relation giving means will be described.
The illustrated press-fitted relation giving means comprises base projection portions 55 formed on the base guide portion 15, and cover projection portions 57 formed on the cover guide portions 45. The base projection portions 55 are formed at deep portions near the base portion 14. The cover projection portions 57 are formed on outer surfaces of the fixing plate portions 45b at portions corresponding to the entrance portion apart from the base portion 14. Herein, a dimension between the base projection portions 55 is set smaller than the sum of thickness dimensions of the cover projecting portions 45a in the state where the cover insulators 26, 27 are mated. A dimension between tips of the cover projection portions 57 is set larger than a dimension between the base plate portions 15a (i.e. the groove width dimension of the base guide groove 16) at the entrance portion of the base guide portion 15.
Now, the cover guide portions 45 of the cover insulators 26, 27 are inserted into the base guide grooves 16 of the base insulator 13. On the way of insertion, tapered tip portions of the cover projecting portions 45a abut against the base projection portions 55. When the insertion is further continued, the cover projecting portions 45a are press-fitted into between the base projection portions 55. Thereafter, when the fixing plate portions 45b are fully inserted into the base guide grooves 16, the press-fitting of the cover projecting portions 45a into between the base projection portions 55 is completed.
In this event, the wires 21 contact with the socket portions 11 a of the contacts 11 so that the connected state is obtained. Since the cover projecting portions 45a are firmly press-fitted to the base projection portions 55 to be retained thereby, even if the cables 23, 24 are rocked upward, downward, leftward, or rightward by an external force, possibility is small that the connected state is loosened. Particularly, inasmuch as it is configured that the press-fitted relation is achieved immediately before the connected state is obtained, the insertion of the cover insulators 26, 27 relative to the base insulator 13 can be smoothly carried out with a small force.
Referring to Fig. 15, another specific example of the press-fitted relation giving means will be described.
In the illustrated press-fitted relation giving means, the cover guide portion 45 further comprises a cover projection portion 58. The one cover projection portion 57 is formed at a position of the base guide portion 45 corresponding to the entrance portion, while the other cover projection portion 58 is formed at a position of the cover guide portion 45 corresponding to the deep portion. That is, the one cover projection portion 57 is formed on the outer surface of the cover projecting portion 45b, while the other cover projection portion 57 is formed on the outer surface of the fixing plate portion 45a. Incidentally, the groove width dimension of the base guide groove 16 is constant.
Even with such cover projection portions 57, 58, the cover guide portions 45 are press-fitted into the base guide grooves 16 to be retained thereby. Therefore, even if the cables 23, 24 are rocked upward, downward, leftward, or rightward by an external force, possibility is small that the connected state is loosened.
Referring to Fig. 16, another specific example of the press-fitted relation giving means will be described.
The illustrated press-fitted relation giving means comprises base projection portions 55 formed at a deep portion of the base guide groove 16 so as to narrow the groove width thereof, and base projection portions 59 formed at an entrance portion of the base guide groove 16 so as to narrow the groove width thereof.
Even with such base projection portions 55, 59, the cover guide portions 45 are press-fitted into the base guide grooves 16. Therefore, even if the cables 23, 24 are rocked upward, downward, leftward, or rightward by an external force, possibility is small that the connected state is loosened.
Referring to Figs. 17 and 18, description will be made of a cable connector according to a second embodiment of the present invention. Like portions are assigned the same symbols to thereby omit description thereof.
The illustrated cable connector comprises two plates 61, 62 received between cover insulators 26, 27 and fixed with end portions of cables 23, 24 on outer sides thereof. The cover insulators 26, 27 have mutually confronting surfaces on which concave portions 26a are formed for retaining the plates 61, 62, respectively. The plates 61, 62 are fixed to both surfaces of the cables 23, 24, respectively. The cables 23, 24 are sandwiched between the cover insulators 26, 27 so as to be retained.
Referring also to Fig. 19, an assembly process of this cable connector will be described.
At the outset, the plates 61, 62 are fixed to the cables 23, 24. Using this as a reference, coatings of the cables 23, 24 are partly stripped by the use of a stripping machine to expose wires 21. Then, the cables 23, 24 are fixedly fitted to the concave portions 26a of the cover insulators 26, 27 shown in Fig. 14, using double-coated tapes 36 or adhesives. Further, after winding the wires 21 around connection contact portions 28a of cable-connection contacts 28, the wires 21 are cut into a fixed length dimension at winding ends, so that the wires 21 are set in connection grooves 31.
In the connected state, since the plates 61, 62 are received in the concave portions 26a of the cover insulators 26, 27, a retaining force for the cables 23, 24 can be set sufficiently large.
Referring to Figs. 20 to 22, description will be made of a cable connector according to a third embodiment of the present invention. Like portions are assigned the same symbols to thereby omit description thereof.
In the illustrated cable connector, cables 23, 24 have crank portions 23a, 24a each formed into a crank shape. Cover insulators 26, 27 have clamp grooves 71a, 71b for receiving the crank portions 23a, 24a inserted therein, and locking holes 73.
Further, the cable connector comprises locking members (cable clamp members) 75a, 75b for retaining/fixing the cables 23, 24 to the cover insulators 26, 27.
The locking members 75a, 75b are each formed into a generally ⊐-shape in section by pressing a metal plate to bend both end portions thereof in a longitudinal direction at a substantially right angle in the same direction. During the assembly operation for fixing the cables 23, 24 to the cover insulators 26, 27, in the state where the cables 23, 24 are processed into the crank shape and stripped portions of the cables 23, 24 are arrayed on the cover insulators 26, 27, the locking members 75a, 75b are driven into the locking holes 73 of the cover insulators 26, 27 to be press-fitted/fixed thereto in such a manner as to cover the crank portions 23a, 24a. In this state, the cables 23, 24 are fixed to the cover insulators 26, 27. By driving a base insulator 13 having contacts 11 provided in a base portion 14 in the state where the two sets of them are united together face to face, the connection is completed.
Referring to Figs. 23 and 24, description will be made of a cable connector according to a fourth embodiment of the present invention. Like portions are assigned the same symbols to thereby omit description thereof.
In the illustrated cable connector, a cable 23 has a crank portion 23a formed into a crank shape. A cover insulator 27 has a clamp groove 81 for receiving the crank portion 23a inserted therein, and locking holes 83.
Further, the cable connector comprises a locking member (cable clamp member) 85 for retaining/fixing the cable 23 to the cover insulator 27.
The locking member 85 has both sides in a longitudinal direction formed with a pair of locking portions 85a extending at a right angle in the same direction. The pair of locking portions 85a enter the locking holes 83 to be engaged with locking projections 88 formed in the locking holes 83.
When outer coating of one cable 23 is thin and weak, damage can be reduced by employing such a locking member 85. An assembly operation of this cable connector is carried out like the case of the cable connector as described with reference to Figs. 20 to 22.
The foregoing description has been given about the example wherein the two cables are sandwiched between the two cover insulators and, by uniting the two insulators together, the two cables are retained/fixed, and the example wherein the one cable is sandwiched using the one cover insulator. However, it is needless to say that it is possible to configure such that three or more cables are retained/fixed by three or more cover insulators, or retained/fixed by three or more plates.

The cable connector of the present invention is suitable as a connection device for connecting a cable used in a computer, a portable telephone, or the like.
