Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an information outlet serving as a wiring device for indoor information wiring.

[0002]

2. Description of the Related Art Conventionally, when constructing a LAN (local area network) system using Ethernet,
A twisted pair cable in which a twisted pair wire of 8 cores is housed in a sheath is widely used. Twisted pair cables have the advantage of being easy to wire because they are relatively inexpensive and flexible. Modular jacks are often used to connect twisted pair cables to each other or to other devices. Therefore, it has been proposed that an information outlet equipped with a modular jack be laid in advance in a suitable place indoors and the information terminal device be detachably connected to the information outlet at a desired location.

When performing high-speed data communication using this type of information outlet, the degree of electrical coupling between signal pairs (in other words, crosstalk) is an important characteristic that affects communication quality. The electrical coupling between the signal pair occurs not only in the twisted pair cable but also in the information outlet, and the degree of electrical coupling changes depending on the positional relationship of the signal pair.

By the way, an information outlet having a plurality of ports for connecting a modular plug is disclosed in Japanese Unexamined Patent Publication No. 10-2088.
As described in Japanese Patent Publication No. 28, etc., it is often configured by mounting a plurality of single-ended modular jacks 6 on a body 60 side by side (see FIG. 20). If an attempt is made to miniaturize this type of information outlet, the distance between the modular jacks 6 is reduced and the modular jacks 6 are
Will be placed close to each other. However, the smaller the distance between the modular jacks 6, the higher the possibility that crosstalk will occur between the signal pairs of the adjacent modular jacks 6, resulting in a problem that the communication quality deteriorates.

By the way, as shown in FIG. 21, a shield (hatched portion) formed of a metal plate is provided around the plug insertion opening 11 into which the modular plug is inserted in the modular jack 6 (the front surface and the outer peripheral surface of the front end portion of the modular jack 6). (Shown) 7 is known. The modular jack 6 is used when connecting a shielded twisted pair cable, and the shield of the twisted pair cable is grounded via the shield 7 of the modular jack 6. That is, by providing a shield on the twisted pair cable, it is intended to reduce external noise to the twisted pair cable and radiation noise from the twisted pair cable.

[0006]

As described above, as shown in FIG.
The modular jack 6 shown in FIG. 10 is applied to a shielded twisted pair cable, and considers electrical coupling between signal pairs when a plurality of modular jacks 6 as shown in FIG. 20 are arranged side by side. However, the electrical coupling between signal pairs cannot be sufficiently suppressed. The modular jack 6 shown in FIG. 21 has a structure to be mounted on a printed circuit board.

The present invention has been made in view of the above circumstances, and an object of the present invention is to electrically couple a signal pair of adjacent modular jacks when a plurality of modular jacks are arranged side by side. It is to provide an information outlet with little deterioration in communication quality.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) As shown in FIGS. 1 and 2, a plurality of modular jacks 6 are coupled to a body 60.

The body 60 includes a front plate 62 having a plurality of opening windows 61 for exposing the plug insertion port 11 (see FIG. 7) provided on the front surface of the modular jack 6, and a bottom plate 63 continuous with the front plate 62. Prepare In FIG. 1, only a part of the body 60 is shown, and as the overall shape of the body 60, a box-shaped body similar to the body described in JP-A-10-208828 can be adopted. Plug insertion port 1
An unshielded twisted pair cable is connected to the modular plug inserted in 1.

Locking ribs 6a and locking grooves 6b are formed on both side surfaces of the modular jack 6, and the modular jack 6 is provided in an opening window 61 formed in a front plate 62 of the body 60.
When the front end portion of is inserted, the locking rib 6a is locked to the peripheral edge of the opening window 61. Further, a pair of mounting legs 64 are provided on the bottom plate 63 of the body 60 so as to project upward, and a claw portion 64 a provided at a tip end portion of the mounting leg 64 has a locking groove 6.
The modular jack 6 is fixed to the body 60 by engaging with b. In short, when the locking rib 6a contacts the peripheral edge of the opening window 61, the forward movement of the modular jack 6 with respect to the body 60 is restricted, and the claw portion 64a of the mounting leg 64 is engaged with the locking groove 6b. By this, the rearward movement of the modular jack 6 with respect to the body 60 is restricted, and as a result, the modular jack 6
Is fixed to the body 60.

By the way, a front plate 62 and a bottom plate 63 are provided in a portion of the body 60 corresponding to the space between the adjacent opening windows 61.
A partition plate 65 is provided so as to straddle and. Partition plate 65
Is a metal plate and is electrically disconnected from the signal path inside the modular jack 6. That is, the partition plate 65 has conductivity. Further, the partition plate 65 is provided for each opening window 61.
It is formed so as to cover the side surface of the modular jack 6 attached to the above, and prevents the signal pair from being electrically coupled between the adjacent modular jacks 6. Here, instead of using a metal plate for imparting conductivity to the partition plate 65, it may be formed of a synthetic resin together with the body 60, and a metal plating layer may be formed on the surface of the partition plate 65.

By the way, the modular jack 6 shown in the present embodiment, as shown in FIGS. 3 to 8, is a plug connection base 1 and a terminal base 2 which are molded products of synthetic resin having an insulating property.
With. The terminal base 2 includes a contact 41 and a terminal 42.
And a conductor 4 electrically connected to each other via a connection conductor 43.
(See FIG. 9) is held and connected to the plug connection base 1 to form a modular jack. The conductor 4 is formed by punching out a sheet metal having elasticity, and is attached to the terminal base 2.
The book is held. The terminal base 2 is formed of two members, a base 20 and a holding base 30, and the holding base 30 is a base 2.
It is glued to the upper surface of 0.

The plug connection base 1 is a hollow body in which a plug insertion opening 11 into which a modular plug is inserted is opened in the upper front surface, and a mounting hole 12 into which the front end of the terminal base 2 is inserted is opened in the lower rear surface. The rear wall is formed with eight separation slits 13 that are open to the upper edge of the mounting hole 12. Further, a pair of upper and lower locking ribs 6a are projected on the left and right side surfaces of the plug connection base 1, and a locking groove 6b is formed between the upper and lower locking ribs 6a.

The base 20 is provided with a connecting support piece 21 that abuts the lower surface of the plug connection base 1 at the front end, and a holding base mounting plate 22 on which the holding base 30 is mounted at the rear end. The lower surface of the plug connection base 1 is formed with a connecting groove portion 14 having a width substantially equal to the left-right width of the connecting support piece 21, and a coupling protrusion 15 formed in a substantially T shape is formed on the inner bottom surface of the connecting groove portion 14. It A substantially T-shaped coupling hole 23 that can be engaged with the coupling protrusion 15 is formed in the coupling support piece 21. The coupling hole 23 is provided with a notch groove 23a which is opened in the front edge of the connecting support piece 21 as desired, and the notch groove 23a improves the flexibility of the front end portion of the connecting support piece 21. In addition, insertion locking pieces 24 are provided on both sides of the base of the connection supporting piece 21 at positions displaced upward with respect to the connection supporting piece 21, and the insertion locking pieces 24 are attached to the mounting holes formed in the plug connection base 1. 12 is inserted in the lower part. Then, the insertion locking piece 24 is locked inside the plug connection base 1, and the connection support piece 21 abuts the lower surface of the plug connection base 10, whereby the base 20 is temporarily held by the plug connection base 1. become.

On the other hand, the holding table 30 has a contact supporting table 31 for holding the contacts 41 at the front end thereof, and a terminal 42.
Is provided at the rear end with a terminal support base 32 protruding toward the upper surface. A lever support base 33 is provided on the upper surface of the terminal base 2 so as to project between the contact support base 31 and the terminal support base 32. A positioning groove 34 for positioning the conductor 4 is formed in the front end portion of the contact support base 31 and the lower surface of the holding base 30. In addition, the terminal support 32 is formed with a terminal insertion hole 35 penetrating vertically and through which the terminal 42 is inserted.

To connect the terminal base 2 to the plug connection base 1, the contact support base 31 is inserted into the mounting hole 12 with the base 20 and the holding base 30 adhered to each other. Terminal base 2
Engaging protrusions 31a are provided on both side surfaces of the contact support base 31, and the inner surface of the plug connection base 1 guides the terminal base 2 in a state of being engaged with the engaging protrusions 31a. Ditch 1
0a is formed. Therefore, when the terminal base 2 is moved forward in a state where the engaging protrusion 31a is engaged with the engaging groove 10a, the holding base 30 causes the holding protrusion 30 to engage with the engaging groove 31a.
The position of the base 20 is regulated by a and
Since the position is regulated by 1 and the connecting groove portion 14, the terminal base 2 can be inserted to a predetermined position while regulating the position with respect to the plug connection base 1. When the terminal base 2 is inserted to a fixed position, a lever support base 33 or the like formed on the intermediate portion of the terminal base 2 in the front-rear direction abuts the rear surface of the plug connection base 1, whereby the plug of the terminal base 2 is plugged. The amount of insertion into the connection base 1 is restricted.

Further, the coupling projection 1 provided on the plug connection base 1
5, the coupling hole 23 of the base 20 is engaged, and the plug connection base 1
On the other hand, the rearward movement of the terminal base 2 is prohibited. At this time, the insertion locking piece 24 of the base 20 together with the contact support piece 31 of the holder 30 attaches to the mounting hole 12 of the plug connection base 1.
Inserted in. Here, when a downward force is applied to the rear end portion of the terminal base 2, the connection support piece 21 tries to move upward with the insertion locking piece 24 as a fulcrum, but the connection support piece 21 does not move in the plug connection base 1. Since it is in contact with the lower surface, upward movement is prohibited, and consequently, the rear end portion of the terminal base 2 is prevented from moving downward. Further, when an upward force is applied to the rear end portion of the terminal base 2, the connection support piece 21 tries to move downward with the insertion locking piece 24 as a fulcrum, but the lever support base 33 is the rear surface of the plug connection base 1. The movement of the terminal base 2 is prohibited because it is in contact with the terminal base 2, and consequently the rear end of the terminal base 2 is prohibited from moving upward. Although the engagement protrusions 31a and the engagement grooves 10a also contribute to the vertical movement restriction of the terminal base 2, the vertical movement restriction is more reliably performed by the above-described action. In short, the plug connection base 1 and the terminal base 2 are joined by engaging a part of them, but they are firmly joined so that rattling does not occur.

The contacts 41 are arranged on the contact support base 31 from the front end portion to the rear upper direction, and the terminal base 2
When inserting the contact support base 31 of the above into the plug connection base 1, each contact 41 is introduced into each separation slit 13, and each contact 41 is guided by each separation slit 13. With the terminal base 2 coupled to the plug connection base 1, the rear ends of the contacts 41 are kept inserted in the separation slits 13, and the contacts 41 are separated so as not to contact each other. By thus inserting the contact 41 into the plug connection base 1, the plug insertion opening 11
The contact 41 can be elastically contacted with the contact of the modular plug inserted into the plug connection base 1 through the contact 41.

The modular jack of the illustrated example is for connecting a twisted pair cable 1 of 4 to 8 cores, and eight conductors 4 are held on a terminal base 2. Each conductor 4
The terminal 42 provided in the terminal is the terminal insertion hole 35 provided in the holding table 30.
Is inserted from below to project from the upper surface of the terminal support base 32,
It is arranged in two rows. The terminal 42 is of a press-contact type formed in a fork shape having a press-contact slit 42a whose upper edge is opened between a pair of teeth, and the press-contact slit 42a.
Is set to such a degree that both side edges of the pressure contact slit 42a are in pressure contact with the core wire of the electric wire to be connected. That is, when an electric wire having an insulation coating is press-fitted into the press-contact slit 42a from above, the insulation cover of the electric wire is cut at both side edges of the press-contact slit 42a to remove the insulation cover and press-connect the slit 42a.
A core wire is introduced into the inside of the pressure contact slit 42a, and the core wire is sandwiched between both side edges of the pressure contact slit 42a. This terminal is a known one also called an IDC terminal.

By the way, in the illustrated example, in order to connect the electric wires to the terminals 42 without using a separate tool or jig, the aligning function for holding a plurality of electric wires together and the electric wires for pressure contact with the terminals 42 are provided with the slit 42a. A pair of levers 5 made of a synthetic resin molded product having a press-fitting function of being press-fitted into are provided. Although both levers 5 are formed in different shapes, they are formed in symmetrical shapes on the left and right. However, both levers 5
Is symmetrically formed as described above, so in the following,
Only one lever 5 will be described.

The lever 5 is rotatably supported via a rotary shaft 50 with respect to a bearing portion 33a formed integrally with each lever support base 33. The rotary shaft 50 is fixed through a shaft hole 51 provided in the lever 5, and together with the lever 5, the bearing portion 33a.
Rotate against. That is, the lever 5 has the bearing portion 33a.
It is rotatable around the center of the terminal base 2 and can be undulated between a position where the terminal base 2 is covered and a position where the terminal base 2 is opened. The rear surface side of the bearing portion 33a is open.

Here, the maximum angle at which the lever 5 is raised is restricted by the contact between the lever 5 and the plug connection base 1 as shown in FIG. That is, when the lever 5 is raised in the plug connection base 1, the portion where the lever 5 abuts (that is, the upper part of the rear surface of the plug connection base 1) is the inclined surface 10b that is inclined rearward, and when the lever 5 is raised. In addition, the upper surface of the terminal base 2 is opened sufficiently wide. Since the inclined surface 10b is formed on the upper portion of the rear surface of the plug connection base 1 as described above, the range of rotation of the lever 5 can be increased, and when the lever 5 is raised, the rear surface of the lever 5 is connected to the terminal board. The table 2 can be made substantially orthogonal to the upper surface of the table 2. Also, lever 5
The upper surface of the lever 5 in the state where the lever 5 is tilted (state of the solid line in FIG. 4) is curved so as to be convex upward at the front and rear intermediate portions, and when the lever 5 is raised, the upper portion of the inclined surface 10b described above is a fulcrum. As a result, the rotary shaft 50 can be removed from the bearing portion 33a. In this way, lever 5
Since the part that is relatively distant from the rotary shaft 50 can be used as the fulcrum when removing the lever, the work of removing the lever 5 is facilitated.

By the way, the terminal support base 3 of the lever 5
On one surface on the second side, three separating plates 52 that separate and hold the electric wires connected to the terminals 42 are provided in a protruding manner. A separation passage through which each electric wire passes is formed between each side wall of the lever 5 and the separation plate 52 or between the adjacent separation plates 52, and a holding projection 53 is provided at a proper position in each separation passage. This allows the wires to be attached to and detached from the separation passage. That is, the electric wire inserted into the separation passage is held by the holding projection 53 so as not to fall off. Further, a separation hole 54 for separating and holding the tip portion of the electric wire is formed in a portion of the lever 5 near the rotation shaft 50. Therefore, the electric wires can be aligned between the separation passage and the separation hole 54. Since the work of aligning the electric wires is performed before connecting the electric wires to the terminals 42, the lever 5 is raised at this time, and the rear surface when the lever 5 is raised is the upper surface of the terminal base 2 as described above. On the other hand, since the openings are substantially orthogonal to each other and largely open, the work of passing the electric wire through the separation passage and the separation hole 54 becomes easy.

On the other hand, the lever 5 has a separation passage and a separation hole 5.
Two press-fitting grooves 55 running in the axial direction of the rotary shaft 50 are formed in a portion between the two. Each press-fitting groove 55 is formed so that the tip of the terminal 42 is inserted when the lever 5 is brought close to the terminal base 22, as shown in FIG. 10, and the wire is pressed against the terminal 42 before and after the press-fitting groove 55. I am allowed to do so. In short, when the lever is brought close to the terminal base 2 while the lever 5 holds the electric wire, the electric wire is pressed before and after the press-fitting groove 55, so that the electric wire is press-fitted into the press-contact slit 42a of the terminal 42. In this sense, the lever 5 has an electric wire aligning function and a press-fitting function.

By the way, in the lever 5, the terminal support 3
An opening 57 into which a part of the terminal support 32 is inserted is formed on one side surface of the portion corresponding to 2. this is,
This is because the left and right width of the terminal support base 32 can be made larger than that when the terminal support base 32 is housed between both side surfaces of the lever 5. Further description will be made. There is a limit to widen the left and right width of the terminal base 2, while the distance between the terminals 42 needs to be relatively large.
When the left and right width of 2 is small, the distance between the terminal 42 and the side surface of the terminal support base 32 becomes small, and the terminal support base 32 becomes thin,
The strength of the terminal support 32 cannot be sufficiently secured, and the terminal support 32 may be damaged when the electric wire is press-fitted into the terminal 42. On the other hand, as in the above configuration, the lever 5
By forming the opening 57 on one side surface, it becomes possible to widen the left and right width of the terminal support base 32 within the limited left and right width of the terminal base base 2 and improve the strength of the terminal support base 32. It can be done.

When the lever 5 is tilted, as shown in FIG. 8, the pawl 36a of the locking hook 36 which is erected on the rear surface of the terminal base 2 (holding base 30) is located on the side of the lever 5. It is adapted to engage with the locking claw 56a at the tip of the extended movement restricting piece 56 to prevent the lever 5 from being easily opened. That is, since the lever 5 has a function of pressing the electric wire as described above, by preventing the lever 5 from being opened, even if an external force is applied to the electric wire, it is difficult for the lever 5 to come off from the terminal 42. Further, when the lever 5 is tilted, the lower surface of the movement restricting piece 56 abuts on the upper surface of the base portion 38 protruding from the upper surface of the terminal base 2, and the movement of the lever 5 is restricted. That is, if the movement restricting piece 56 is not provided, the bearing portion 33a may be damaged when a large force acts on the lever 5 when the lever 5 is tilted. Since the force can be received by the movement restricting piece 56 by abutting on a part of the above, it is possible to prevent the bearing portion 33a from being damaged.

As described above, the terminal base 2 is formed by stacking and adhering the base 20 and the holding base 30, and the contact supporting base 31 provided on the holding base 30 of the terminal base 2 is used. Since the connection support piece 21 of the base 20 is engaged with the lower surface of the plug connection base 1 while being inserted into the mounting hole 12 of the plug connection base 1, they are relatively bonded when the base 20 and the holding base 30 are bonded. It does not slide, and as a result, if the amount of adhesive applied is appropriate, the adhesive will not stick out between the base 20 and the holding table 30. In other words, it is possible to prevent the appearance of the adhesive from being spoiled and the product specifications from not being satisfied due to the adhesive protruding, which facilitates the manufacturing process and improves the yield. Further, when the electric wire is connected to the terminal 42 by the lever 5, a relatively large downward force acts on the terminal base 2, but as described above, the terminal base 2 moves up and down with respect to the plug connection base 1. It is difficult to do so, and it is possible to prevent an uncomfortable feeling when connecting the electric wire and to prevent the terminal base 2 from being damaged.

Reference Example In this example , as shown in FIG. 11, a body 60 having no partition plate is used. However, a shield portion (hatched portion) 8 made of a metal plate is provided on one side surface of the modular jack 6 over the entire surface. The shield portion 8 is electrically independent of the internal wiring of the modular jack 6 and functions similarly to the partition plate in the first embodiment. That is, due to the presence of the shield portion 8, electrical coupling between the signal pairs of the adjacent modular jacks 6 is reduced, and deterioration of communication quality can be reduced. Here, it is desirable that the size of the shield portion 8 be formed so as to include the entire range in which the internal wiring of the modular jack 6 is projected on the side surface of the modular jack 6. The shield portion 8 may be a synthetic resin plate plated with conductive material instead of a metal plate. Further, the shield portions 8 may be provided on both sides of the modular jack 6, or may be formed all over the periphery of the modular jack 6. Other configurations and operations are similar to those of the first embodiment.

( Second Embodiment ) In the above-mentioned embodiment, an example in which the base 20 and the holding base 30 are adhered has been shown. However, the base 20 and the holding base 30 are joined by engaging with each other. Good. That is, FIG.
As shown in FIG. 17, one of the peripheral portions of one of the base 20 and the holding base 30 (the base 20 in the illustrated example) except for one side located on the lower surface side of the plug connection base 1 has one side each. The connecting hooks 25 are continuously erected on a book-by-book basis. In addition, a coupling groove 37 that engages with the coupling hook 25 is formed on the peripheral portion of the other side (holding table 30 in the illustrated example). A coupling claw 25 a is provided on the upper end of each coupling hook 25 so as to project inward of the base 20. Also, each coupling hook 25
Near the lower end of the through hole 26 extending vertically through the base 20.
Is formed. The through hole 26 is formed for the convenience of forming the coupling hook 25a, but has a function of facilitating the coupling hook 25 together with the notches 25b formed on both sides of the lower end portion of the coupling hook 25.

On the other hand, the holding table 30 has the shape shown in FIG. 18, and the connecting hook 2 is provided on the peripheral portion of the holding table 30 as described above.
A coupling groove 37 that engages 5 is formed. Here, by engaging the coupling hook 25 with the coupling groove 37, the coupling hook 25 abuts on the three side surfaces of the holding base 30, and the coupling hook 25 is housed in the coupling groove 37, and the base 20
Since a part of the base 20 and the holding base 30 abuts on the plug connecting base 1 and is prohibited from moving forward, as a result, the base 20 and the holding base 30 are relatively opposed to each other in a plane along the facing surfaces of the base 20 and the holding base 30. Movement is prohibited. In short, the coupling hook 2 as a protrusion
The relative movement between the base 20 and the holding table 30 is prohibited by the connecting groove 5 as 5 and the recess. The coupling claw 25a locks the upper surface side of the holding table 30 to prevent the holding table 30 from floating from the base 20. Therefore, the coupling hook 2
