2. Description of the Related Art An electronic exchange has, for example, a plurality of exchange units housed in a cabinet thereof. The exchange unit includes a printed circuit board having a board connector in a housing thereof. The housing of the exchange unit is conductive, and the conductive housing electromagnetically shields the printed circuit board. A part of the conductive housing is used as a ground plate by grounding. When electrically connecting board connectors in the same electronic exchange and between board connectors in another electronic exchange, a cable connector electrically connected to a cable with an electromagnetic wave shield is used.

FIG. 1 shows how a cable connector 111 connected to a shielded cable 119 is fitted and connected to a board connector 103 via a ground plate 101 of an exchange unit. The board connector 103 is formed of an insulator 1 holding a terminal pin 105 disposed in the internal space.
07. On the other hand, the cable connector 111
Are the signal line 121 of the cable 119 and the board connector 1
03, a female contact 115 electrically connected to each of the terminal pins 105, a contact housing 117 for accommodating the female contact 115, a conductive shield shell (not shown), and an insulating cover 118 surrounding the shield shell. And an electrical contact 113 extending from the shield shell and exposed from a gap between the contact housing 117 and the insulating cover 118.

[0004] The cable 119 has a configuration in which a plurality of signal lines 121 are surrounded by a jacket. These signal lines 121 are electrically connected to the respective female contacts 115, and the jacket shield is electrically connected to the shield shell of the cable connector 111. At the time of mating connection of the connector, the electrical contact 113 is elastically brought into contact with the conductive ground plate 101 to secure electrical connection, and a shield ground path from the cable 119 to the ground plate 101 is formed. Has formed.

However, the electric contact 113 shown in FIG. 1 is of a cantilever type in which the spring piece is straight. Electrical contact 11 with straight spring piece
In No. 3, since the spring length from the supporting end (the fulcrum of the spring) supported by the shield shell to the contact end, which is the point of action, is short, a spring that generates a larger displacement with respect to the load (a so-called big spring constant value). (Rigid) spring, which results in a narrow spring displacement area for obtaining a necessary and sufficient contact force. The position accuracy of the ground plate 101 with respect to the cable connector 111 is not good, and the amount of protrusion of the contact end of the electrical contact 113 varies. When the distance becomes large, the contact state of the electric contact 113 with the ground plate 101 is no longer good (sufficient spring force cannot be secured), so that the impedance of the shield ground path increases, There is a problem that the shield grounding effect is reduced.

[0006]

SUMMARY OF THE INVENTION Therefore, the technical problem to be solved by the present invention is that when a cable connector connected to a shielded cable is fitted and connected to a mating connector via a ground plate, a shielded cable connector is required. An object of the present invention is to provide a cable connector in which a shield ground path from a cable with a cable to a ground plate has low impedance. It is another object of the present invention to provide a connector system including the cable connector and a communication device using the connector system.

[0007]

In order to solve the above-mentioned technical problems, the present invention provides a method of electrically connecting a signal line to a shielded cable in which a signal wire is shielded by an outer shield, and A contact connector fitted with a connector via a grounding plate via a ground plate, the contact housing including a first contact electrically connected to a signal line, and the contact housing electrically connected to a jacket shield. And a shield shell that covers the shield shell, and an insulating cover that covers the shield shell.
One end is formed of a bent spring piece that is supported by the shield shell and bent in a substantially U-shape, and is electrically connected to the ground plate when the cable connector is fitted to the mating connector. It is characterized by having a contact.

According to the cable connector having the above-described structure, the cable connector is formed of a bent spring piece having one end supported by the shield shell and bent substantially in a U-shape on the surface facing the mating connector. Has an electrical contact that elastically contacts the ground plate when fitted to the mating connector. That is, the bent spring piece is typically substantially U-shaped, but also includes one bent into a substantially V shape, a substantially W shape, a substantially bellows shape, or the like. About U
The cable-side end of the bent spring piece is fixed and supported with respect to the shield shell.

In the case of a substantially U-shaped bent spring piece, when one end (first support end) of the U-shape on the cable side is fixed and supported on the shield shell, one end fixed and supported by the shield shell is used. Becomes the fulcrum of the spring, and the U-shaped bent portion becomes the action point of the spring. Further, the bent portion also serves as a fulcrum for the other end of the U-shape (the end on the side of the mating connector). Then, the other end on the side of the mating connector becomes the final point of action. In the bent spring piece bent in a substantially U shape, one end on the cable side serves as a fulcrum of the spring, the other end on the mating connector side serves as a final application point, and the entire length of the substantially U-shaped spring piece is a spring. Work as head. As described above, since the spring of the bent type can have a longer spring length than the spring of the straight shape, the spring constant of the spring piece can be made smaller than that of the conventional straight spring. Thereby, a wide spring displacement area for obtaining a necessary and sufficient contact force can be secured. Therefore, due to the fact that a stable contact (force) is obtained between the spring piece and the ground plate, the electrical connectivity of the electrical contact to the ground plate is improved, and the shielded cable is connected to the ground plate. The resulting shield ground path has low impedance.

It is preferable that the electric contact has a support portion extending from the end of the bent spring piece on the cable side in the connector fitting direction on the cable side and supported by a shield shell. According to such a configuration, the end of the bent spring piece on the cable side is fixed and supported by the support portion supported by the shield shell. Since it can withstand the elastic force acting when the bent spring piece abuts against the ground plate, the supportability of the electrical contact is improved,
A stable contact can be obtained. Therefore, the electrical connectivity of the electrical contact to the ground plate is improved.

[0011] It is also possible to adopt a configuration in which a part of the support portion of the electrical contact is supported on the shield shell. In the support portion having the above configuration, one end of the bent spring on one side of the portion supported by the shield shell functions as a fulcrum of the spring, and a portion not supported by the shield shell is a spring action portion. That is, in addition to the bent spring piece,
The portion not supported by the shield shell acts as a spring. Therefore, the spring length of the electrical contact becomes longer than in the case where the support is supported almost entirely on the shield shell. Therefore, based on the above-mentioned principle, further stable contact with the ground plate can be obtained because the spring constant of the spring piece can be made smaller. Therefore, the electrical connectivity of the electrical contact to the ground plate is further improved.

Preferably, at least one pair of the electrical contacts is used. According to such a configuration, even if there is a displacement in the connector fitting direction between the electrical contact and the ground plate, any one of the electrical contacts absorbs the displacement, so that a stable state can be obtained. Contact can be obtained. Therefore, the electrical connectivity of the electrical contact to the ground plate is improved.

Preferably, the electric contact is formed integrally with the shield shell. A processed part of a shape corresponding to the electrical contact is provided in advance on the shield shell,
Processing such as folding of the processed portion is performed to create an electrical contact having a predetermined shape. Therefore, the number of parts and the number of manufacturing steps can be reduced, and the cost can be reduced, as compared with the case where the separately prepared electrical contact is later attached to the shield shell.

In the connector system arranged on the ground plate between the cable connector and the mating connector,
When the cable connector is fitted and connected to the mating connector, the electrical contact of the cable connector elastically contacts the ground plate, thereby forming a shield ground path between the two. In the connector system, the electrical contact stably contacts the ground plate with a necessary and sufficient spring force for the same reason as described for the cable connector, so that a low-impedance shield ground path is formed. And electromagnetic noise from outside can be reduced.

The board connector and the cable connector as the mating connectors are applied to a communication device having a plurality of units each having a printed circuit board inside a box-shaped conductive casing. That is, in a communication device, a part of the conductive casing of the unit is grounded to form a grounding plate, and the grounding plate is arranged between the board connector provided on the printed board and the cable connector having the electrical contact. It has a configuration. In the communication device having such a configuration, when the cable connector is fitted and connected to the board connector, the electrical contact stably contacts the ground plate for the same reason as described for the connector system. In addition, the printed circuit boards incorporated in each unit can be connected by a low impedance shield grounding path, so that the mixing of external electromagnetic noise can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cable connector 10, a connector system 80 including the cable connector 10, and the connector system 80 according to an embodiment of the present invention will be described below.
An electronic exchange using the method will be described in detail with reference to FIGS.

FIG. 2 is a perspective view showing a cable connector 10 connected to a shielded cable (not shown). FIG. 3 is an exploded perspective view of the cable connector 10 of FIG.

The cable connector 10 includes a contact housing 12, a cable-side shield shell 14 surrounding the contact housing 12, an insulating cover 18, a latch member 22, and a cable clamp member 28.

Contact housing 12 having a rectangular shape
Is formed by molding an insulating resin material (for example, an insulating resin such as PBT, PCT, or nylon). The lower wall of the contact housing 12 has a first guide 13a formed with a guide groove, and the front wall of the contact housing 12 has terminal holes 13 arranged in a matrix (for example, at a pitch of 2 mm). I have. Each terminal hole 13 is provided with a female contact (first contact) 17. The female contact 17 is made of a copper alloy for a spring, and it is preferable to apply a gold plating process to an electrically contacting portion. The female contact 17 has a connection portion with the signal line of the cable at the end portion on the cable side, and has a connection portion with the terminal pin 46 at the end portion on the substrate side.

The cable-side shield shell 14 is made of a conductive material such as a copper alloy, for example, and has a box shape that covers the contact housing 12. The cable-side shield shell 14 having a box shape is a combination of two parts, an upper shield shell 15 and a lower shield shell 16 each having a U-shaped cross section. The lower shield shell 16 includes a bottom wall 32 and two side walls 31. A cable clamp is provided at the end of the bottom wall 32 on the cable side. The cable clamp portion is for connecting to the cable clamp member 28 that grips the exposed jacket shield.

The lower shield shell 16 is provided on both side walls 3.
On one substrate connector side, there is a contact mounting portion 33 extending toward the substrate connector 40. At each of the upper and lower end portions of the contact attachment portion 33, two pairs of support portions 34 extending in a direction orthogonal to the contact attachment portion 33 and in the connector fitting direction, that is, a total of four support portions 34 Is provided. The support part 34 forms a part of an electric contact 30 described later, and is fixed to the contact attachment part 33.
Supported.

That is, the electrical contact 30 is a plate-like spring piece made of the same conductive material as the cable-side shield shell 14 such as a copper alloy, and a bent spring piece 36 bent substantially in a U-shape. And a support portion extending from the cable-side end of the bent spring piece and supported by the contact mounting portion 33 of the lower shield shell 16. The electrical contact 30 has a so-called “LU overlapped” shape in which the “U” -shaped right piece is superimposed on the “L” -shaped bottom piece. In the cable connector 10, two pairs of electrical contacts 3
0, that is, a total of four electrical contacts 30 are provided in the contact mounting portion 33.

The bent spring piece 36 bent in a U-shape at the second support end 35b has one end (first support end) on the cable side.
35a is a contact mounting portion 33 of the lower shield shell 16.
Is fixed and supported via a support portion 34. The end (terminal working end) 35c on the board connector side is freely displaced in the connector fitting direction. At this time, one end (first support end) 35a on the cable side becomes a fulcrum of the spring,
The U-shaped bent portion (second support end) 35b is the point of action of the spring. The bent portion 35b functions as a fulcrum with respect to the end portion (terminal action end) 35c on the board connector side.
c serves as the final point of action.

Therefore, in the electrical contact 30 having the “LU overlapped” shape, one end (first support end) 35 a of the bent spring piece 36 on the cable side serves as a fulcrum of the spring, and the board connector of the bent spring piece 36 is formed. The side end (end working end) 35c is the final working point. The length of the bent spring piece 36 functions as the spring length in the bent spring piece 36 having the “LU overlap” shape. Therefore, in the U-shaped bent spring piece 36, the spring length is long, so that the spring constant can be reduced, and as a result, a spring displacement region capable of securing a necessary and sufficient (predetermined) contact force can be widened. Thereby, even when the distance between the ground plate 60 and the ground plate 60 is deviated, the deviation is absorbed, and a stable contact with a substantially predetermined spring force can be secured.

The electrical contact 30 can be made by various methods. For example, it can be made by the following method. That is, at each end of the contact attachment portion 33, two strip-shaped plates extending in a predetermined length toward the board connector are formed in advance. Both strip plate members are bent at an angle of about 90 degrees toward the center line of the contact attachment portion 33. After that, the first support ends 35a are formed by bending the rectangular plates at an angle of about 90 degrees so that the free ends 35c of the two strips protruding from the contact attachment portion 33 face each other. Then, the second supporting end 35 is bent into a substantially U-shape so that the free end 35c of the strip-shaped body faces the board connector side.
b is formed, and a U-shaped bent spring piece 36 is formed.

In the electric contact 30, the bent spring piece 3
6 is configured integrally with the support portion 34,
Further, the electrical contact 30 is integrally formed with the contact mounting portion 33, so that the number of parts and the number of manufacturing steps can be reduced, and the cost can be reduced. In addition, the electric contact 30
May be configured as a separate member from the lower shield shell 16. For example, an electrical contact 30 having a “LU superimposed” shape is separately prepared in advance, and the electrical contact 30 is fixed to the side end of the contact attachment portion 33 by various known methods such as screwing or welding. I do.

In the surface of the bent spring piece 36 on the board connector side, two portions near the free end 35c are slightly bent toward the cable side to form a substantially planar contact portion 38. By providing the substantially planar contact portion 38, the contact with the contact plate 60 can be improved.

The insulating cover 18 that covers the cable-side shield shell 14 has a box shape, and is a combination of two parts, an upper insulating cover 19 and a lower insulating cover 20 each having a U-shaped cross section. is there. A concave portion is formed on the upper surface of the upper insulating cover 19. The latch member 22 is housed in the recess and is supported by a pivot provided in the recess.

The latch member 22 has a latch 24 in a region in front of an arm 23 extending in the fitting connection direction.

Are provided with through-holes arranged in a matrix (for example, at a pitch of 2 mm), and conductive terminal pins (second contacts)
46 is fixed to the printed circuit board 44 by a method such as press-fitting into a through hole. Then, both end portions of the terminal pins 46 fixed to the printed board 44 project toward the circuit side and the board connector 40 side, respectively. After the board connector 40 is positioned at a predetermined position on the surface of the cable connector 10 side, the board connector 45 is engaged with the printed board 44 by using the locking portion of the board housing 45 to be integrated with the printed board 44. The printed circuit board 44 is usually provided with a plurality of board connectors 40.

Next, referring to FIGS. 6 to 9, a connector system 80 including the cable connector 10, the board connector 40, and the ground plate 60 described above is applied to an electronic exchange 90 in which an exchange unit containing the printed circuit board 44 is housed. Next, a case where the board connectors 40 of the printed circuit board 44 are electrically connected in a shield ground state will be described.

Each exchange unit 93 contains at least one printed circuit board. The exchange unit 93 is formed of a conductive housing and shields a built-in printed circuit board. A part of the conductive case, for example, the back plate 94 is connected to the ground as the ground plate 60. Each printed circuit board mounted inside the conductive housing has at least one board connector described above. Each board connector is fitted and connected to a cable connector 95 connected to a shielded cable 96. The cable connector 95 connected to the shielded cable 96 electrically connects the exchange units 93 in the electronic exchange 90 or electrically connects units of communication equipment such as another electronic exchange.

The shielded cable 96 shown in FIG.
Has a plurality of signal lines, a conductive outer shield that surrounds and shields these signal lines, and an insulating coating that covers the outer periphery of the outer shield. The outer shield exposed by peeling off the insulating coating at the cable end is tightened and electrically connected to the conductive cable clamp member 28, and the cable clamp member 28 is connected to the cable clamp portion of the lower shield shell 16 of the cable connector 10. Electrically connected to and secured. Then, each signal line is electrically connected to and fixed to the female contact 17 of the cable connector 10, respectively. Therefore, when the shielded cable 96 is connected to the cable connector 10, both a shield path and a signal transmission path are formed therebetween.

As shown in FIG. 6, the grounding plate 60 is positioned at a position corresponding to each of the board connectors 40.
Each opening is provided so as to be able to be inserted and removed. This opening includes a housing opening 62 for inserting the contact housing 12 and a latch member opening 64 for inserting the latch member 22.
The grounding plate 60 shown in FIGS. 6 to 8 includes not only a portion corresponding to one connector system but also an upper half and a lower half corresponding to a connector system disposed above and below the same. That is, the ground plate 60 used in one connector system is a portion surrounded by a substantially rectangular frame 61. Contact portions 66 provided on upper and lower frames in the figure
Is for contacting the electrical contact 30. The grounding plate 60 is attached to the exchange unit 93 in FIG. 9 in a state where a receiving space for the board connector 40 appears from the opening of the grounding plate 60.

0, the cable connector 10 is connected to the board connector 4
The formation of the shield ground path between the exchange units 93 of the electronic exchange 90 at the time of fitting connection to 0 will be described in detail.

The board connector 40 whose receiving space is exposed from the opening of the contact plate 60 and the shielded cable 96
And a cable connector 10 that is electrically connected. The cable connector 10 is so adjusted that the contact housing 12 of the cable connector 10 matches the opening shape of the contact plate 60 and the receiving space of the board connector 40.
Position. When the contact housing 12 is inserted into the receiving space of the board connector 40, the first guide 13a of the cable connector 10 is guided along the guide groove 43 of the board connector 40, and the cable connector 10 is fitted and connected to the board connector 40.

When the connector is fitted and connected, the latch member 2
The second latch 24 is engaged with the locking hole 47 of the board connector 40, the terminal pin 46 of the board connector 40 is fitted into the female contact 17 of the cable connector 10, and the electrical contact 30 of the cable connector 10 is sufficient. The spring comes into contact with the contact portion 66 of the ground plate 60 by a spring force. Since the bent spring piece 36 can reduce the spring constant of the spring piece, a wide spring displacement area capable of ensuring a predetermined contact force can be obtained. Spring force can be secured. Therefore, a signal transmission path is formed, and a low-impedance shield ground path is established through the jacket of the shielded cable 96, the cable-side shield shell 14, the electrical contact 30, and the ground plate 94. As a result, the external electromagnetic noise taken in from the shielded cable 96 falls to the ground through the shield grounding path, so that a sufficient shielding effect can be obtained.

The cable-side shield shell 14 of the cable connector 10 and the board-side shield shell of the board connector 40 have a first contact portion and a second contact portion (not shown), respectively. When the cable connector 10 is fitted and connected to the board connector 40 via the ground plate 60, the first contact portion makes electrical contact with the second contact portion, and the cable side shield shell 14 and the board side shield A conductive path is formed with the shell. Therefore, the board side shield shell,
A shield ground path can be established through the cable side shield shell 14, the electrical contact 30, and the ground plane 60.

The bent spring piece 3 bent into a U-shape
The same effect can be obtained by bending the V-shaped member 6 into a V shape, a W shape, a bellows shape, or the like.

A slit or the like is provided between the support portion 34 of the electric contact 30 and the contact mounting portion 33 of the lower shield shell 16 so that a part of the support portion 34 is
May be supported.

In the support portion 34 having the above-described structure, a portion on the cable side, that is, a base end support portion 34a is supported by the contact mounting portion 33 of the lower shield shell 16, and a portion on the board connector side is connected to the lower shield shell 16 Are not supported by the contact mounting portion 33. Accordingly, the base end support portion 34a serves as a fulcrum of the spring, and the end (first support end) 35a of the support portion 34 on the board connector side serves as a point of action of the spring.

Accordingly, in the electrical contact 30 having the “LU overlapped” shape, the base support portion 34 a of the support portion 34 serves as a spring fulcrum, and the end portion of the U-shaped bent spring piece 36 on the board connector side. (Terminal working end) 35c is the final working point. In the spring piece 36 having the “LU superimposed” shape, the length of the portion of the lower shield shell 16 that is not supported by the contact mounting portion 33 (the unsupported portion of the bent spring piece 36 and the support portion 34) functions as the spring length. Therefore, the support 3
The spring length of the electric contact 30 is further longer than when the contact 4 is supported almost entirely on the contact mounting portion 33.
Since the spring constant of the electric contact 30 can be made small and small, a spring displacement area capable of securing a predetermined contact force can be widened, and thereby a necessary and sufficient spring force can be provided between the electric contact 30 and the ground plate 60. Can be secured. Therefore, the electrical connectivity of the electrical contact 30 to the ground plate 60 is improved.
