Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modular jack mainly for communication and to which a plurality of twisted pair wires are connected.

[0002]

2. Description of the Related Art Conventionally, modular jacks have been used to connect communication cables to each other or to other devices. In particular, when constructing a LAN (Local Area Network) system using Ethernet, a twisted pair cable having a 4 to 8 core twisted pair wire housed in a sheath is widely used for relatively short distance communication (10BASE- T etc.). This kind of cable
It is relatively inexpensive and has the advantage that it is easy to wire because the cable is thin.

By the way, the modular jack has a housing having a plug insertion port into which a modular plug is detachably inserted, and a contact of a modular plug inserted into the housing can be contacted in the housing through the plug insertion port. The contacts are arranged. Further, the housing is provided with a terminal portion for connecting to an electric wire such as the above-mentioned twisted pair wire, and the contact and the terminal portion are electrically connected to each other through a connection conductor arranged in the housing. The terminal part is formed in the shape of a fork with a pressure contact slit between a pair of teeth, and by inserting the wire into the pressure contact slit, a pressure contact type terminal piece that sandwiches the core wire while stripping the insulation coating of the wire is easy to connect. It has been used a lot since.

[0004]

By the way, in the modular jack provided with the above-mentioned pressure contact type terminal piece, when the electric wire is press-fitted into the pressure contact slit of the terminal piece, the electric wire at both side edges of the pressure contact slit of the terminal piece. Since the core wire is sandwiched while stripping the insulating coating, a required force is required for press fitting. Therefore, at present, a special jig in the form of a cap that covers the terminal piece is used, and the wire is pushed into the press-contact slit of the terminal piece by the jig by pressing the jig to one side of the terminal using a general-purpose tool such as pliers. Like that. That is, in order to connect the electric wire to the terminal strip, a dedicated jig and a tool such as a plier are required. In addition, as described above, when connecting a 4-to-8-core electric wire, it is troublesome to connect the electric wires one by one. Therefore, it is better to connect a plurality of electric wires at a time, but the wiring work should be more efficient. If an attempt is made to perform the work, it is necessary to hold the electric wires in a state where a plurality of electric wires are aligned and arranged in the arrangement order of the terminal pieces, and as a result, the wiring work becomes difficult. That is, the conventional configuration cannot improve the efficiency of the wiring work.

The present invention has been made in view of the above circumstances. A first object of the present invention is to connect wires with a relatively small force without using a dedicated jig or tool even though the pressure contact type terminal piece is provided. It is to provide a modular jack that improves work efficiency of wiring work by enabling work to be performed.

As shown in FIGS. 1 to 4, the housing 10 includes a body 10 made of a molded product of a synthetic resin, which is an insulating material, and a housing 20. The housing 20 has a contact 31 and a terminal piece 32 via a connecting conductor 33. The electrically conductive body 30 (see FIG. 13) electrically connected is held. Eight conductors 30 are provided and are formed by punching an elastic sheet metal.

The body 10 is integrally provided with a connection base 11 in which a plug insertion port 13 into which a modular plug is inserted is opened on the front surface, and a base 12 extended rearward from the lower rear surface of the connection base 11. The connection board I1 is formed in a hollow shape, and a mounting hole 14 into which the insert 20 is inserted is opened in the lower portion of the rear wall. Further, a comb-teeth-shaped separation slit 15 is formed on the rear wall of the connection base 11 so as to face the upper edge of the mounting hole 14.

The insert 20 has a contact support base 21 for holding the contacts 31 at the front end thereof, and a terminal base 22 having a terminal piece 32 projecting to the upper surface side is formed at the rear end thereof. Further, a wall plate 23 is formed continuously and integrally with the contact support 21 and the terminal block 22 so as to partition the contact support 21 and the terminal block 22. To connect the insert 20 to the body 10, the contact support base 21 is inserted into the mounting hole 14. Engagement ridges 21a are provided on both side surfaces of the contact support base 21 of the insert body 20, and the insert body 20 is engaged with the engagement ridge 21a on the inner side surface of the connection base 11 of the body 10. Is formed with an engaging groove 11a. Therefore, when the insertion body 20 is moved forward with the engagement protrusion 21a engaged with the engagement groove 11a, the insertion body 20 can be inserted to a predetermined position while the position of the insertion body 20 is restricted with respect to the body 10. .

When the insert body 20 is inserted to the fixed position, the front surface of the wall plate 23 of the insert body 20 contacts the rear surface of the connection base 11,
The insert 20 is positioned with respect to the body 10. That is, the front surface of the wall plate 23 functions as a locking surface that regulates the amount of insertion of the insert 20 into the body 10. Further, a contact 31 is provided on the contact support base 21 so as to project from the front end portion toward the upper rear side. When the contact support 21 of the insert body 20 is inserted into the connection base 11 of the body 10, the contact 31 is separated by a slit. Introduced in 15. Insert 2
The rear end portion of the contact 31 is kept inserted in the separation slit 15 at the position where the wall plate 23 of 0 abuts on the rear surface of the connection base 11, and the contacts 31 are prevented from contacting each other. By inserting the contact 31 into the connection base 11 in this way, the contact 31 can elastically contact the contact of the modular plug inserted into the connection base 11 through the plug insertion port 13.

A retaining recess 12a is formed on the upper surface of the rear portion of the base 12.
Is opened, and as shown in FIG.
With respect to the fixed position, the retaining projections 22a are provided on the lower surface of the terminal block 22 provided on the insert 20.
By engaging with the retaining recess 12a in a concave-convex manner.
The position of 0 with respect to the body 10 is fixed. That is,
The retaining recess 12a and the retaining projection 22a constitute a fixing means. Here, the retaining projection 22a is formed in a wedge shape in which the protruding amount increases toward the rear side, and it hardly interferes with the forward movement of the insert 20, but the retaining projection 22a does not interfere with the retaining recess 1a.
After engaging with 2a, it has a shape that prohibits backward movement.

As described above, the engaging projections 1 are formed in the engaging grooves 11a.
2a engages, the mounting hole 14 engages the contact support base 21, and the connection base 11 abuts the wall plate 23,
Further, since the retaining projection 22a engages with the retaining recess 12a,
The insert 20 is fixed in place with respect to the body 10.
In addition, the terminal block 22 provided on the rear portion of the insert 20 is placed on the base 12 in a state where the insert 20 is coupled to the body 10.

The modular jack shown in this embodiment has four
This is for connecting the twisted pair cable 1 of 8 cores, and holds the eight conductors 30 in the insert body 20.
The terminal pieces 32 of each conductor 30 protrude from the upper surface of the terminal block 22 and are arranged in two rows in the front and rear. As shown in FIG. 8, the terminal piece 32 is a press-contact slit 32 having an upper edge opened between a pair of teeth.
a pressure contact type formed in a fork shape having a, and the width of the pressure contact slit 32a is the core wire 2 of the electric wire 2 to be connected.
It is set so that both side edges of the pressure contact slit 32a are in pressure contact with a. That is, as shown in FIG. 9A, the insulating coating 2b
When the electric wire 2 having the above is press-fitted into the press-contact slit 32a from above, the core wire 2a is introduced into the press-contact slit 32a by cutting the insulating cover 2b of the electric wire 2 at both side edges of the press-contact slit 23 and peeling the insulating cover 2b. Slit 32a
The core wire 2a is sandwiched between both side edges of the.

In order to connect the electric wires 2 to the above-mentioned terminal piece 32 without using a separate tool or jig, in the present invention, an aligning function for holding a plurality of electric wires 2 together and an electric wire 2 are provided. Fixture 40 having a press-fitting function of press-fitting into the press-contact slit 32a of the terminal piece 32, and the fixture 40
Lever 5 that exerts a force in the direction to bring the terminal closer to the terminal block 22.
0 and are provided. The fixture 40 and the lever 50 are molded products of synthetic resin and are provided in pairs.

Each lever 50 has a housing (body 10 and body 10) by pivotally supporting a rotary shaft 51 provided on the lever 50 with respect to a pair of bearings 24 continuously and integrally projected on the upper rear surface of the wall plate 23 of the insert 20. It can be raised and lowered with respect to the insert 20). That is, the lever 50 can be undulated between the position where the terminal block 22 is covered and the position where the terminal block 22 is opened. The lever 50 is formed in a shape in which the rotary shaft 51 is continuously and integrally provided between a pair of left and right arm pieces 52 projecting from one end in the longitudinal direction. The bearing 24 is open at the lower surface side. The rotating shaft 51 is inserted into the bearing 24. That is, the lever 50 is attachable to and detachable from the insert body 20. Here, as shown in FIG. 5, the stop surface 52a on which the arm piece 52 is provided is a stop surface provided on the outer surface of the bearing 24 at a predetermined position when the lever 50 is raised in a direction away from the terminal block 22. By abutting against 24a, the maximum angle for raising the lever 50 is restricted.

Each fixture 40 is placed on the terminal block 22 with the lever 50 opened as shown in FIG. As will be described later, the fixing tool 40 is self-standing in this state, and when the lever 50 is tilted, the fixing tool 40 is pressed by the lever 50 as the lever 50 rotates, and the fixing tool 40 moves downward as shown in FIGS. 6 and 7. Move to. Each fixture 40 is formed in a rectangular tube shape into which the electric wire 2 is inserted, and the inside of the tube is formed by a partition wall 41 as shown in FIG.
It is divided into four separation passages 42 each having a rectangular cross section. The electric wire 2 is inserted into each of the separation passages 42 one by one. Further, the separation passage 42 may have a constant opening cross-section, but if it is formed in a shape such that the introduction side of the electric wire 2 has a larger opening cross-sectional area than the protruding side, as shown in FIG. It becomes easy to introduce the electric wire 2 into the separation passage 42. That is, since the minimum value of the opening cross-sectional area of the separation passage 42 is set to be substantially equal to the cross-sectional area of the electric wire 2, the centers of the separation passage 42 and the electric wire 2 must be substantially aligned with each other. It is difficult to insert the electric wire 2 if the opening cross-sectional area on the introduction side is small, but by adopting the above shape, the electric wire 2
Since the opening cross-sectional area of the separation passage 42 can be made larger than the cross-sectional area of the electric wire 2 on the introduction side, the work of introducing the electric wire 2 into the separation passage 42 becomes easy.

By the way, when connecting the electric wire 2 to the terminal piece 32, it is necessary to move the electric wire 2 along the protruding direction of the terminal piece 32. Therefore, the electric wire 2 is held in the fixture 40. In order to connect the terminal block 40 to the terminal block 32, it is necessary to regulate the moving direction so that the terminal block 40 moves along the protruding direction of the terminal piece 32. Therefore, a guide projection 43 is provided at the center of the lower surface of the fixture 40, and a guide hole 25 having an opening shape matching the cross-sectional shape of the guide projection 43 is formed in the terminal block 22 provided in the insert 20. There is. here,
Since two fixtures 20 are provided for one insert 20, two guide holes 25 are also formed. Further, the base 12 of the body 10 is formed with an insertion hole 16 into which the guide protrusion 43 can be inserted at a portion corresponding to the guide hole 25. The guide protrusion 43 has a substantially U-shaped cross section so that the fixture 40 does not rattle forward, backward, left and right.

Since the fixture 40 is used for press-fitting the electric wire 2 into the terminal piece 32, it can be moved vertically from the position where the electric wire 2 contacts the upper end of the terminal piece 32 to the position where the electric wire 2 is completely connected to the terminal piece 32. It suffices if the base 12 and the terminal block 2 are positioned such that the lower end of the guide protrusion 43 is located in either the insertion hole 16 or the guide hole 25 in this movement range.
The relationship between the thickness of No. 2 and the protrusion size of the guide protrusion 43 is set.

Further, guide ribs 45 are provided so as to project from the left and right ends of the front surface of the fixture 40, and the tip end surfaces of both guide ribs 45 contact the rear surface of the wall plate 23 of the insert 20. Therefore, the guide rib 45 is brought into sliding contact with the wall plate 23, so that the forward movement of the fixture 40 is restricted. In addition, a guide receiving portion 26 that is sandwiched between a pair of guide ribs 45 provided on the fixture 40 is provided at the lower rear portion of the wall plate 23 so as to project. Therefore, the guide receiving portion 2 is provided between the two guide ribs 45.
By sandwiching 6 the movement of the fixture 40 in the left-right direction is restricted. Thus, the guide rib 45, the wall plate 23, and the guide receiving portion 26 have a function of restricting the moving direction of the fixture 40, and cooperate with the guide protrusion 43 and the guide hole 25 to fix the fixture 40 to the terminal piece 32. It is moved without rattling in the protruding direction of.

At the lower end of the guide protrusion 43, the temporary holding protrusion 4 is provided.
3a is projected rearward, and a latch projection 43b is projected rearward at an intermediate portion of the guide projection 43. Temporary holding protrusion 43a
The projecting dimensions of the latch projection 43b and the latch projection 43b are substantially equal to each other, and can be engaged with the holding projection 25a provided at the upper end of the guide hole 25. That is, as shown in FIG. 5, before the guide protrusion 43 is inserted into the guide hole 25, the temporary holding protrusion 43a is placed on the holding protrusion 25a, so that the fixture 40 is locked in place. In this state, the fixture 40 is supported by the guide ribs 45, the wall plate 23, and the guide receiving portion 26, so that it is self-supporting. Further, when the electric wire 2 is inserted into the fixture 40, the electric wire 2 is connected to the terminal piece 32 as shown in FIG.
The temporary holding protrusion 43a can be positioned below the holding protrusion 25a to prevent the fixture 40 from falling off when not connected to the holding protrusion 25a. In this state, the fixture 40 cannot move backward, so that the work of adjusting the position of the electric wire 2 inserted into the fixture 40 becomes easy. After the fixture 40 moves downward, the latch protrusion 43b is formed as shown in FIG.
Is fixed to the holding projection 25a, so that the fixture 4
The floating of 0 will be prevented.

Since the temporary holding protrusion 43a or the latching protrusion 43b of the fixture 40 is only locked to the holding protrusion 25a of the insert 20, the fixture 40 can be removed from the insert 20. That is, the fixture 40 is detachable from the insert 20. The terminal block 2 is provided at the rear end of the insert 20.
The open removal groove 27 is formed on the upper surface and the rear edge of the tool 2, so that a gap for tool insertion is formed between the rear portion of the fixture 40 and the bottom surface of the removal groove 27 while the fixture 40 is pushed down. I am doing it. Therefore, as shown in FIG.
The fixture 40 can be removed by inserting the tip of a flat-blade screwdriver into the gap and pushing up the fixture 40 with the rear edge of the removal groove 27 as a fulcrum. That is,
The removal groove 27 functions as a release part.

Two guide receiving portions 26 are provided on the wall plate 23, and each of the guide receiving portions 26 is formed with four separating grooves 26a running in the vertical direction. Each separation groove 2
6a is formed at a position corresponding to the separation passage 42 provided in the fixture 40, and the tip of the electric wire 2 inserted in the fixture 40 is inserted into the separation groove 26a to separate the tip of the electric wire 2. .

By the way, since the fixing tool 40 presses the electric wire 2 introduced into the separation passage 42 into the terminal piece 32,
When the fixture 40 moves downward, the electric wire 2 is connected to the terminal piece 32.
So that it can be pressed into the pressure contact slit 32a of
The holding parts 46a to 46c as shown in FIG. 7 are provided. The holding portions 46a to 46c are formed on the upper surface of the separation passage 42, and the upper end portion of the terminal piece 32 is introduced between the holding portions 46a to 46c adjacent to each other in the front and rear. That is, the terminal piece 3
2 are arranged in two rows in the front and rear as described above, so that the pressing portions 46a are located at corresponding positions between the terminal pieces 32 in each of the front and rear rows.
And the pressing portions 46b, which are positioned with the terminal pieces 32 in the front and rear rows sandwiched therebetween, with respect to the pressing portions 46a,
46c are provided. By arranging the holding portions 46a to 46c in this manner, a pressing force can be applied to the electric wire 2 before and after the terminal piece 32 and at a distance close to the terminal piece 32, so that the pair of holding portions 46a to 46c can be pressed. The electric wire 2 can be press-fitted into the terminal piece 32 without being bent. That is, the pressing force of the fixture 40 can be efficiently transmitted to the electric wire 2.

A pressing rib 47 that abuts the lever 50 is provided on the upper surface of the fixture 40 in a protruding manner. The pressing rib 47 is the electric wire 2
In the position where is not connected, the point of action of the pressing force from the lever 50 to the fixture 40 is provided above the rotation shaft 51 that is the swing fulcrum of the lever 50. The lower surface of the front end portion of the lever 50 is formed in an arc shape, and when the lever 50 is tilted, the rotational force of the lever 50 is transmitted to the pressing rib 47, and the fixture 40 moves downward. Here, by changing the shape or size of the pressing rib 47 or the shape of the lower surface of the lever 50, the lever 5
Since the position of the point of application of the pressing force from 0 to the fixture 40 can be changed, the fixture 4 can be rotated by the rotational force of the lever 50.
A highly flexible design is possible so that 0 can be moved downward with a desired pressing force. The angle range of the undulation of the lever 50 is regulated by the position where the stop surfaces 24a and 52a contact and the position where the fixture 40 contacts the terminal block 22, and this angle range is set to 90 degrees or more. ing. Therefore, it is easy to confirm the insertion state of the electric wire 2 inserted in the fixture 40 when the lever 50 is opened.

In order to connect the twisted pair cable 1 to the above-mentioned modular jack, connect the electric wire 2 to each fixture 40 with 4 wires.
The books are inserted one by one, and the fixture 40 is mounted between the terminal block 22 and the lever 50. In this state, separate the tip of the wire 2 into the separation groove 2
When the position is adjusted so as to be inserted into 6a and the lever 50 is tilted, the fixture 40 moves downward and the electric wire 2 is connected to the terminal piece 53. Since the moving direction of the fixture 40 is restricted to the vertical direction as described above, the electric wire 2 is connected to the terminal piece 3
2, the terminal piece 32 is not moved by the force in the thickness direction at this time, and the terminal piece 32 is not bent.

Further, the rotary shaft 51 which is the fulcrum of the lever 50
From the fulcrum to the rear end of the lever 50 that applies a pressing force to the lever 50, as compared with the distance from the contact position to the pressing rib 47, which is the point of application of the pressing force. Therefore, each electric wire 2 can be pushed into the press contact slit 32a with a relatively small force. Moreover, 8
Since the four electric wires 2 are divided into four when connecting them, the force required for the connection is small as compared with the case where the eight electric wires 2 are simultaneously connected to the terminal piece 32, and as a result, the lever 5 is connected.
The length of 0 can be shortened. That is, it leads to miniaturization. Furthermore, by simply applying a force to the lever 50 so that the housing and the lever 50 are sandwiched,
Since each electric wire 2 can be pushed into the press contact slit 32a, no additional jig or tool is required, and the connection work can be performed only with the modular jack. In this state, the fixture 4
Since the latch protrusion 43b of 0 is locked to the holding protrusion 25a of the insert 20, the fixture 40 keeps the electric wire 2 connected to the terminal piece 32.

The fixture 40 has a lower wall 42a formed only at the rear portion of the separation passage 42. This lower wall 42a is an electric wire 2
Has a function of pulling out the electric wire 2 from the terminal piece 32 by pushing the electric wire 2 upward together with the fixing tool 40 when the fixing tool 40 moves upward from the state in which is connected to the terminal piece 32, Functions as a wire removal member. That is, as described above, when the electric wire 2 is connected to the terminal piece 32, a tool such as a flat-blade screwdriver is inserted into the removal groove 27, and the fixture 40 is moved upward. It is possible to release the connection state of the electric wire 2 with the terminal piece 32 with the movement to. Further, when the fixture 40 moves up to the position where the temporary holding protrusion 43a contacts the holding protrusion 25a, the electric wire 2 can be pulled out from the fixture 40.

By the way, each contact 31 and each terminal piece 3
2 are connected so as to have a relationship shown in FIG.
1 and the terminal piece 32 are connected to each other). The terminal pieces 32 are arranged so as to be plane-symmetric in the left-right direction. That is, the two terminal pieces 32 on the center side in the front row (the upper row in FIG. 13) are located between the two terminal pieces 32 on the center side in the rear row, and the left and right terminal pieces 32 sandwich the plane of symmetry. , One terminal piece 3 in the rear row between each of the two terminal pieces 32 in the front row
2 is located, and one terminal piece 32 in the front row is arranged between two terminal pieces 32 in the rear row. By arranging the eight terminal pieces 32 in this way, the lateral dimension required to arrange the terminal pieces 32 can be reduced as compared with the case where the terminal pieces 32 are arranged in one row. That is, the lateral width of the housing (body 10 and insert 20) can be reduced.

By providing eight terminal pieces 32, four pairs of twisted pair wires can be connected, and each twisted pair wire is connected to the front and rear terminal pieces 32 that are adjacent to each other in the left-right direction. That is, the two electric wires 2 that are paired as a twisted pair wire are connected to the leftmost terminal piece 32 in the rear row (the lower row in FIG. 13) and the leftmost terminal piece 32 in the front row, and the second electric wire 2 from the left end in the rear row. Two electric wires 2 forming a pair as twisted pair wires are connected to the two terminal pieces 32, which are the second from the left end in the front row, and the remaining electric wires 2 are also connected so that they are adjacent to each other in pairs.

Each electric wire 2 has an insulating coating, and the color of the insulating coating is defined by ANSI / EIA / TIA-568 (commercial building communication wiring standard). That is, as shown in FIG. 14, when the contacts 31 are arranged so as to project from the top to the bottom when viewed from the front of the plug insertion opening 13, the terminal numbers are assigned in the order of from left to right. The color code of the electric wire electrically connected to the contact 31 (color assignment of the insulation coating) is defined as follows. White-orange, orange, white-green, blue,
White-blue, green, white-brown, and brown (white-X (X: orange, green, blue, brown) are white and X).
Represents that the color is colored the entire length). Further, the connection relationship is defined so that the contacts 31 ,,, and are paired. In other words, the wire that makes a pair of twisted pair wire is a color wire whose insulation coating is a single color,
The insulating coating is formed by twisting a white ground wire, which is two colors of white and other colors, and the color of the white ground wire which is not white is the same as the color of the pair of color wires. For example, when the white line has two colors, white and green, the color line is paired with green.

Since the pair of is arranged between the pair of, if the connection conductor 33 is formed on one plane, it is formed by the capacitance component between the connection conductors 33. The bridge circuit becomes unbalanced. That is,
The crosstalk current easily flows between the pair and the pair, and the crosstalk current increases especially when the frequency of the signal becomes high. Also, for other pairs, the crosstalk amount increases as the frequency increases.

Therefore, the crosstalk amount is reduced by arranging the connection conductors 33 for electrically connecting the contacts 31 and the terminal pieces 32 in three layers and adjusting the width and interval of the connection conductors 33. For example, is placed in the upper layer, the middle layer, and the rest in the lower layer. Further, the crosstalk amount is also reduced by changing the arrangement order of the connection conductors 33 and the arrangement order of the contacts 31 (particularly).
In order to change the arrangement order without intersecting vertically, the connection conductor 33 and the contact 31 are arranged so that the position of the connection portion is shifted. In practice, the distance between the left and right of the contact 31 cannot be changed, so that the positions of the contacts 31 and the connection conductors 33 can be arranged by shifting the front and rear positions of the connecting portion (it is also possible to shift the upper and lower positions). They are swapping. Specifically, contact 3
1 indicates that the position of the connection portion with the connection conductor 33 is another contact 3
The connection conductor 33, which is located rearward of the first connection portion,
The wrap-around portion 3 that passes through the front portion of the connection portion of the contact 31 and detours so as to be connected to the contact 31.
3a is formed. Further, as described above, in order to connect the pair of electric wires 2 to the adjacent terminal pieces 32, the connection conductor 33 is formed with the wrap-around portion 33b that detours so as to pass behind the connection conductor 33. In addition, as is clear from FIG. 13, since the left and right of the contact 31 and the connection conductor 33 are reversed for each pair of ,,, so that the contact of the modular plug contacting the contact 31 is contacted in each of these pairs. The relationship between the left and right arrangement and the left and right arrangement of the connection conductors 33 can be reversed. As a result, when the modular plug is connected, an unbalanced current having a phase opposite to that of the unbalanced current generated in the modular plug is generated in the connection conductor 33, and the unbalanced currents of the two cancel each other out, further reducing the crosstalk amount. To be done.

With these configurations, the amount of crosstalk is reduced, and therefore the leakage suppressing portion for suppressing the amount of crosstalk can be formed without the conductors 30 crossing vertically. In this way, the crosstalk amount can be suppressed without crossing the conductors 30 vertically, so that the conductors 30 can be suppressed.
It is easy to manufacture because there is no need for bending for crossing.

Contact 31, terminal piece 32, and connecting conductor 3
3 is a lead frame-like continuous and integrally formed by punching out an elastic metal plate (alloy) having a thickness of about 0.4 mm, and the connection conductor 33 and the contact 31 and the terminal piece arranged in the same layer. 32, connection conductor 33 is 1
It is formed by punching out a metal plate. That is, the three metal plates 3a having the shapes shown in FIGS.
By punching 3c, it is possible to form a conductor portion for three layers. The metal plates 3a to 3c can be continuously punched by supplying them as a hoop material as in the case of forming a lead frame for an integrated circuit.

The metal plates 3a to 3c punched and formed in the above-mentioned shape are inserted into the insert body 2 in such a manner that three layers are superposed in order.
It is attached to 0. The contact 31 is bent after the metal plates 3a to 3c are attached to the insert 20 and the frame portion is removed. In this way, since bending is hardly required, the processing is easy. Here, the conductor pattern formed on each of the metal plates 3a to 3c is formed in such a shape that the contacts 31 and the terminal pieces 32 are mounted on the insertion body 20 and do not cross each other in a bent state. Therefore, there is no restriction on the stacking order of the metal plates 3a to 3c except that the stacking order is set in consideration of the crosstalk characteristic. Moreover, by arranging the connecting conductors 33 so as to be displaced in the thickness direction of the insert body 20, the degree of freedom in designing the distance between conductors and dimensions is increased, and the capacitance component between each pair of connecting conductors 33 is increased. The balance can be almost balanced, and the crosstalk amount can be reduced. By the way, as described above, the pair of contacts 31 are sandwiched between the pair of contacts 31. However, by forming the wraparound portions 33a and 33b in the connection conductor 33, the pair of terminal pieces 32 can be separated. They are next to each other. The terminal pieces 32 are arranged in this order so that the color lines and white background lines of the paired lines to be connected are alternately arranged. With such an arrangement, the color line and the white background line that make a pair are connected to the adjacent terminal pieces 32, and the color line and the white background line are alternately arranged. It can be easily recognized, and as a result, misconnection can be reduced. This leads to improvement in construction reliability. Since the left and right sides in FIG. 13 are interchangeable, the wraparound portion 33a may be provided in the connecting portion 3.

The modular jack A constructed as described above may be housed in an outer case for mounting on a construction surface such as a wall. Various things can be used for the outer case, but in view of the preceding wiring,
It is desirable to use an outer case having the same shape as a general wiring device. Therefore, as shown in FIG. 18, it has the same size and shape as a unit size wiring device that can be attached to a mounting frame for three large squares which is standardized by the JIS standard as an embedded wiring device. The outer case 60 is used. The unit size means that up to 3 units can be mounted on the mounting frame, and the outer case 6
At 0, a mounting portion that engages with the mounting frame is provided. Therefore, by using the outer case 60, up to three can be attached to the mounting frame, and by fixing the mounting frame to the construction surface using a switch box or the like, the outer case 60 can be mounted on the construction surface. Can be fixed.

If a synthetic resin material is used as the mounting frame, since the holding holes are formed in both side pieces of the mounting frame, the mounting claws 61 project on both side surfaces as the mounting portions that engage with this mounting frame. The installed outer case 60 is used. Further, the outer case 60 is formed by connecting the body 60a and the cover 60b, and the assembly claw 62 projecting from the cover 60b is engaged with the assembly hole 62 provided in the body 60a. Thus, the body 60a and the cover 60b are joined together. Positioning ribs 64 for locking the positioning step portions 11b provided on both side surfaces of the connection base 11 are provided on the inner peripheral surface of the cover 60b, and the positioning ribs 64 are provided when the modular jack A is housed in the outer case 60.
The front end surface of the serves as a positioning surface. Also, body 6
The rear wall of 0a (upper wall in FIG. 18) holds the modular jack A by pressing the modular jack A.
It can be fixed within zero. An operation window 65 for exposing the lever 50 is formed in the body 60a so that the lever 50 can be operated in this state. Further, the outer case 60 is provided with doors 66a and 66b that cover the plug insertion opening 13 when not in use, and the doors 66a and 66b are urged by a spring 67 in the closing direction. Further, a pressing plate 68 that holds both side portions of the door 66a between the door 66a and the inner peripheral surface of the cover 60b is also provided.

As the outer case 70, as shown in FIG. 19, it is possible to use an exposed case that is directly fixed to the construction surface such that it is brought into contact with the construction surface such as a wall surface. The outer case 70 is formed by connecting a base 70a and a cover 70b, and a hook claw 78 protruding from the base 70a engages with a recess formed in the inner peripheral surface of the peripheral wall of the cover 70b. By doing so, the cover 70b is coupled to the base 70a. In addition, the base 70a is fixed to the construction surface by using a wood screw, a double-sided adhesive sheet, a magnet or the like (not shown). A fitting concave portion 71 into which the modular jack A is fitted is formed in the base 70a, and a positioning step portion 11 provided in the modular jack A is formed in a part of a peripheral wall of the fitting concave portion 71.
The receiving piece 72 with which b contacts is provided in a protruding manner. The surface of the receiving piece 72 that comes into contact with the positioning step portion 11b functions as a positioning surface. Further, an opening window 73 corresponding to the plug insertion opening 13 is formed on one surface of the base 70a, and openable doors 74a and 74b are attached to the opening window 73. Similar to the embedded outer case 70, the doors 74 a and 74 b are biased by the spring 75 in the closing direction. Further, a spring receiver 76 that receives one end of the spring 75 is attached to the lower surface side of the base 70a. A sandwiching plate 77a having a function of stopping the tension of the twisted pair cable 1 is fixed to the base 70a with a screw 77b.

By using the outer cases 60, 70 as described above, the modular jack A can be fixed to the construction surface by various construction methods. Although the basic embodiment of the present invention is as described above, each component can be replaced with each member described below. Therefore, each replaceable member will be described below for each component.

First, the structure for holding the conductor 30 in the insert 20 will be described. Since the connection conductor 33 of the conductor 30 is sandwiched between the lower surface of the insert 20 and the body 10,
The part where the conductor 30 must be fixed to the insert 20 is the terminal piece 32. As a configuration for fixing the terminal piece 32 to the insert body 20, if productivity is emphasized, a structure in which the insert body 20 and the terminal piece 32 are integrally molded at the same time can be adopted.

As shown in FIG. 20, the wedge-shaped press-fitting protrusions 32b are provided on both side edges of the lower portion of the terminal piece 32 so that the terminal piece 32 can be pressed into the holding hole 22b formed in the terminal block 22. Good. A fixed recess 22c that engages with the press-fitting protrusion 32b is formed on the inner surface of the holding hole 22b, and the terminal piece 32 is fixed at a fixed position with respect to the terminal block 22 by the press-fitting protrusion 32b engaging with the fixed recess 22c. It is retained. With this structure, it is not necessary to add another member and the assembling process is simple, so that the manufacturing cost can be reduced.

Further, as shown in FIG. 21, the terminal piece 32 is inserted from the lower surface side of the terminal block 22, and the conductor 30 is inserted between the holding body 28 mounted on the lower surface side of the terminal block 22 and the terminal block 22.
You may make it pinch a part of. The holder 28 is fixed to the terminal block 20 by a method such as adhesion or welding. Grooves 28a into which the conductors 30 are respectively inserted are formed on the upper surface of the holder 28. In this structure, the use of the holder 28 improves the positioning accuracy of the terminal piece 32. In addition, although the conventional shape of the conductor 30 is illustrated here, it goes without saying that the holding body 28 can be applied to the conductor 30 of the above-described embodiment.

The structure shown in FIG. 20 and the structure shown in FIG. 21 can be used in combination. In that case, the fixing strength of the terminal piece 32 is further increased. In the basic embodiment, the bearing 24 of the lever 50 is replaced by the wall plate 23 of the insert 20.
However, as shown in FIGS. 22 and 23, it may be provided at the upper end of the rear wall of the connection base 11 of the body 10. In this case, the wall plate 23 is lower than the connection board 11. Providing the bearing 24 in the insert 20 improves the positional accuracy of the lever 50 with respect to the terminal block 22, but providing the bearing 24 in the body 10 increases the strength of the bearing 24 and increases the lever 50.
The undulating operation of the becomes smoother.

In the basic embodiment, the wall plate 2 of the insert 20
Although the guide receiving portion 26 that receives the guide rib 45 of the fixture 40 and guides the vertical movement of the fixture 40 is integrally formed with the guide 3, the guide receiving portion 26 is formed separately from the insert body 20. Good. That is, as shown in FIG. 24, a guide block 80 having a guide receiving portion 26 is formed, and the guide block 80 is used to insert the terminal block 22 and the wall plate 23 in the insert 20.
It is fixed by adhesion or welding so as to be in close contact with the corner portion between and. A guide receiving portion 26 is formed in the guide block 80, and a separation groove 26a for separating and aligning the tip end portion of the electric wire 2 is formed in the guide receiving portion 26. In this way, by fixing the guide block 80 provided separately from the insert body 20 to the insert body 20, it is possible to make the insert body 20 function in the same manner as that in which the guide receiving portion 26 is integrally formed. .

As the structure for fixing the insert 20 to the base 10, in addition to the structure in which the retaining projection 12a is engaged with the retaining recess 22a in a concavo-convex manner, as shown in FIG. 25, it is inserted through the through hole 12b drilled in the base 12. The insert 20 may be fixed to the body 10 by screwing the fixing screw 17 to the insert 20. Further, as shown in FIG. 26, the body 10 and the insert 20 may be bonded or welded without providing a specific structure. The coupling work is easy in the configuration in which the retaining projections 12a and the retaining protrusions 22a are engaged as in the above-described basic embodiment, but the fixing strength is increased in the configuration in which the fixing screw 17 or the bonding or welding is performed. Here, these configurations can be combined. Although the retaining projection 22a is provided on the lower surface of the insert 20, it may be provided on the side surface of the insert 20 depending on the shape of the body 10.

Next, a replaceable structure of the fixture 40 will be described. Since the fixture 40 has a function of aligning the electric wires 2, it is desirable to be able to confirm the aligned state of the electric wires 2. So if you make it with a transparent material,
As shown in FIG. 27, the aligned state of the electric wires 2 can be easily visually recognized. The fixture 40 may be opaque, but if it is transparent, not only the aligned state of the electric wires 2 but also the connected state to the terminal piece 32 can be confirmed.

Since the fixture 40 moves up and down as described above, it is provided with the guide projections 43 and the guide ribs 45 to regulate the moving direction. Here, the cross-sectional shape of the guide protrusion 43 is U-shaped as shown in FIG. 28 (a) in the basic embodiment, but is H-shaped in cross section as shown in FIG. 28 (b) or as shown in FIG. 28 (c). You may form in an I-shaped cross section like this. Here, if a cross-sectional shape such as a U-shape or an H-shape in which the straight line portions in the left-right direction and the front-rear direction intersect each other, the fixture 40 can be used rather than the I-shaped one. It becomes difficult to tilt. That is, the moving direction of the fixture 40 can be reliably regulated in the vertical direction. Also, the guide protrusion 4
Since 3 is provided in the vicinity of the central portion of the lower surface of the fixture 40, the moving direction of the fixture 40 can be regulated without widening the lateral width. By the way, by providing a pair of left and right guide ribs 45, it is possible to prevent the fixture 40 from swinging to the left and right, and the tip end surface of the guide ribs 45 is the wall plate 2.
By abutting against 3, the fixture 40 is also prevented from swinging forward.

The fixture 40 holds the electric wire 2 at the position where the electric wire 2 is connected to the terminal piece 32 by engaging the latch projection 43b with the holding projection 25a while the electric wire 2 is connected to the terminal piece 32. There is. This makes it difficult for the electric wire 2 to fall off the terminal piece 32 even when tension is applied to the electric wire 2. That is, the fixture 40 functions as a tension stopper. Further, it is possible to know that the electric wire 2 is connected to the terminal piece 32 by a click sound or a click feeling when the latch protrusion 43b is engaged with the holding protrusion 25a.

As described above, the structure as the latch for holding the fixing tool 40 in the fixed position may be any structure as long as it prevents the fixing tool 40 from being lifted. Therefore, instead of the structure for directly holding the fixing tool 40, as shown in FIG. The lever 50 may be held as described above. That is, the following configuration can be adopted as the lever lock. For example, it is possible to adopt a configuration in which the hooks 29 are erected on the left and right of the rear end of the terminal block 22 and the hooks 29 are locked to the levers 50 when the levers 50 are tilted. In this configuration, the position where the lever 50 is tilted is the position where the fixture 40 connects the electric wire 2 to the terminal piece 32, so that when the lever 50 and the hook 29 are engaged, the latch projection 43b and the holding projection 25a are formed. It will have the same function as when engaged. Here, the lever 50 is formed with a hook groove 53 with which the hook 29 is engaged. If this structure is adopted, the fixture 5 is held and at the same time the lever 5 is held.
It also holds 0, so that the lever 50 can be fixed so as not to move freely while the electric wire 2 is connected to the terminal piece 32.

The hook 29 shown in FIG. 29 has a pillar shape, but as shown in FIG. 30, the body 10 is provided with the left and right side walls 18, and the holding claw 18a is provided on the upper rear end of the side wall 18 to form the hook 29. It can be made to function similarly. Further, since the fixing tool 40 is vertically restricted in its moving direction and the lever 50 is pivotally supported by the housing (the body 10 and the insertion body 20) so that it can be raised and lowered, the fixing tool in a state where the wire 2 is connected to the terminal piece 32. By engaging the lever 40 and the lever 50, the fixture 40 and the lever 50 can be fixed similarly to the hook 29 described above. Therefore, as shown in FIG. 31, a projecting piece 54 that is inserted between the pressing ribs 47 of the fixture 40 is provided on one surface of the lever 50 facing the fixture 40 when the lever 50 is tilted. It is also possible to project the fixing protrusion 54a on the side surface of 54 and to form the fixing recess 47a with which the fixing protrusion 54a is engaged on the side surface of the pressing rib 47. In this configuration, with the lever 50 tilted down to connect the electric wire 2 to the terminal piece 32, the fixing protrusion 54a is fixed to the fixing recess 47.
By engaging with a, the fixture 40 and the lever 50 are coupled, and in this state, the position of the fixture 40 and the lever 50 is fixed.

As a structure for holding the fixture 40 and the lever 50 at the position where the electric wire 2 is connected to the terminal piece 32, FIG.
A configuration in which it is housed in the outer case 70 as in the configuration shown in FIG. That is, if the modular jack A is housed in the outer case 70 as shown in FIG. 19, the lever 50 contacts the inner peripheral surface of the cover 70b. As a result, the positions of the fixture 40 and the lever 50 are fixed.

An important function of the fixture 40 is to press the electric wire 2 into the pressure contact slit 32a of the terminal piece 32, and as described above, the retainer 40 is formed with the holding portions 46a to 46c which come into contact with the electric wire 2. Has been done. The pressing portion 4 described above
6a to 46c are provided on the terminal piece 3 so that the electric wire 2 can be held at a position near the terminal piece 32 before and after the terminal piece 32.
Before and after the part where 2 is provided (holding parts 46b, 46c)
Not only between the two front and rear rows of the terminal pieces 32 (the holding portion 4
It was also provided in 6a). That is, if described schematically, it is provided with three rows of holding portions 46a to 46c as shown in FIG. 32 (the partition wall 41 for forming the separation passage 42 is omitted in the drawing).

The same function can be realized by the shape as shown in FIG. This is one in which two pressing portions 46d and 46e are provided before and after the portion where the terminal piece 32 is provided, and each pressing portion 46d and 46e passes between the adjacent terminal pieces 32 of one row and the other row. Terminal piece 32
Is formed in a shape including a projecting piece 46f extended to a portion facing to. Such a comb-shaped pressing portion 46
By forming d and 46e, the electric wire 2 can be pressed in the vicinity of the terminal piece 32.

The pressing portions 46a to 46c as described above,
When 46d and 46e are provided, compared with the state shown in FIG. 34 (b) in which the holding portion 46 is provided only before and after the portion where the terminal piece 32 is provided, the holding portions 46a to 46c, 46 are provided.
The electric wire 2 can be held in the state where d and 46e are brought close to the terminal piece 32. In the state as shown in FIG. 34 (b), when the pressing portion 46 exerts a pressing force on the electric wire 2, the electric wire 2 may be bent, but the pressing portions 46a to 46c having the above-described configuration, In 46d and 46e, FIG.
As shown in (a), the electric wire 2 is less likely to bend, and as a result, the electric wire 2 can be reliably pressed into the terminal piece 32.

The fixture 40 also has a function as an electric wire removing member for removing the electric wire 2 connected to the terminal piece 32.
That is, the lower wall 4 formed integrally with the fixture 40 continuously.
2a is for connecting the wire 2 to the terminal piece 3 if the fixture 40 moves upward.
Push it up like you pull it from 2. In the basic embodiment, the lower wall 42a is provided only at the rear end portion of the fixture 40, but as shown in FIG. 35, the fixture 40 is substantially the entire length in the front-rear direction except for the portion where the terminal piece 32 is inserted. You may form the lower wall 42a over. In this configuration, since the electric wire 2 is supported before and after the terminal piece 32, it is possible to apply a pulling force to the electric wire 2 connected to the terminal piece 32 substantially evenly before and after the terminal piece 32, and the electric wire 2 is bent. It can be pulled out without fail.

The wire removing member is attached to the lower wall 4 of the fixture 40.
As shown in FIG. 36, the lower surface of the fixing tool 40 may be left open and the wire removing plate 48 separate from the fixing tool 40 may be provided, instead of being shared by the 2a. The electric wire removing plate 48 is shown in FIG.
6 (b), an insertion hole 48a through which the guide protrusion 43 of the fixture 40 is inserted is provided. Therefore, the moving direction of the wire removing plate 48 is regulated in the vertical direction by the guide protrusions 43, and when removing the wire 2, the wire removing plate 48 may be pushed up by using a tool such as a flat-blade screwdriver.

Another important function of the fixture 40 is to function as an aligning member for aligning the electric wires 2. That is, the partition wall 4
The separation passages 42 separated by 1 are provided, and each separation passage 4
Since the electric wires 2 are inserted one by one into the electric wires 2, the electric wires 2 can be aligned at the positions corresponding to the terminal pieces 32. Also,
Before connecting the wire 2 to the terminal piece 32, multiple wires (here, 4
Since the electric wire 2 of this) is held in advance in the fixture 40 in a state of being arranged so as to correspond to the terminal piece 32, it is easy to prevent erroneous connection of the electric wire 2. Furthermore, since the fixture 40 can be removed from the insert 20, the fixture 40 can be removed from the insert 2.
Remove the wire 2 from 0 and insert the wire 2 into the fixture 40.
If the surplus portion of the tip end of the wire is cut in accordance with the end of the fixture 40, the lengths of the electric wires 2 do not become uneven, and the increase in the crosstalk amount is suppressed. However, in order to exert these effects, it is desirable to use the fixture 40 including the lower wall 42a.

The function of aligning the electric wires 2 is that the guide receiving portion 2
6 is also provided with a separation groove 26a. If both the fixture 40 and the guide receiving portion 26 are used, the function of separating the electric wire 2 is enhanced, but only one of them may be used for separating the electric wire 2. When only the fixture 40 has a function of separating the electric wire 2, the guide receiving portion 26 is not provided as shown in FIG. In this configuration, the function of the guide receiving portion 26 engaging with the guide rib 45 is lost, but the function of aligning the electric wires is realized by the fixture 40. Further, as shown in FIG. 38, it is possible to arrange the electric wires 2 only by the separation groove 26a provided in the guide receiving portion 26 without forming the separation passage 42 in the fixture 40. The fixture 40 has a lower wall 42a.
If the internal height dimension is set to such an extent that the electric wires 2 are not interchanged between the left and right in the fixture 40, the electric wires 2 can be aligned even with this configuration.

The separating passage 42 for aligning the electric wires 2 in the fixture 40 is not limited to the rectangular sectional shape separated by the partition wall 41 as described above, and the sectional shape of the separating passage 42 can be changed as shown in FIG. It may be circular according to the cross-sectional shape of the electric wire 2. Some of the fixtures 40 do not have the lower wall 42a as described above, and have a shape whose lower surface is open as shown in FIG. In addition, since the lower surface of the fixture 40 is opened, the guide protrusions 43 are continuously and integrally formed from the partition wall 41, and as a result, the number of the guide protrusions 43 is two.

As described above, since the order of arrangement of the contacts 31 and the color code of the insulation coating of the electric wire 2 is predetermined, when the electric wire 2 is inserted into the fixture 40, the order of arrangement of the terminal pieces 32 is arranged. Must be considered. Therefore, it is desirable to provide a color code display indicating the color code. As shown in FIG. 41, a color code display (for the sake of convenience of the drawing, a shaded line is shown, but a color matching the color code of the electric wire 2 is actually worn) 5a to 5d is associated with the electric wire 2. Provide in a position where you can. The position that can be associated with the electric wire 2 is, for example, the rear end of the insert 20, the rear end of the fixture 40, the upper surface of the body 10, the lever 5.
For example, the front end surface of 0. If the color code indications 5a to 5d are provided at any of these positions, the color shown on the color code indications 5a to 5d when inserting the electric wire 2 into the fixture 40 and the color of the insulation coating of the electric wire 2 It is possible to prevent misconnection by simply combining and. Here, the color code displays 5a to 5d are realized by directly printing or attaching a label.

Since the electric wire 2 is a twisted pair wire, when it is inserted into the fixture 40, the twist must be unwound at the tip. However, if the untwisted dimension is unnecessarily large, the transmission characteristics will change, so the untwisted dimension must be minimized. Further, since there are four pairs of twisted pair wires, if the size of untwisting is different in each pair, the transmission characteristics are affected. Therefore, a gauge 6 is provided as shown in FIG. 42 in order to keep the untwisted dimension constant. The gauge 6 can be provided at an appropriate portion, for example, the lever 5
0, the insert 20, the fixture 40, and the body 10 can be provided. In the illustrated example, one lever 50
It is provided on the upper surface of, and the correspondence relationship between the length of untwisting the electric wire 2 and the length of inserting the electric wire 2 is easy to understand.
The gauge 6 is formed simultaneously with the molding of the lever 50, and is formed in a groove shape or an embossed shape.

Incidentally, although the terminal pieces 32 are arranged symmetrically in the left-right direction, they may be arranged asymmetrically as shown in FIGS. 43 and 44. In this arrangement, the front and rear rows are the same as those described above, but the terminal pieces 32 in the front and rear rows are alternately arranged in the left-right direction. That is, the terminal pieces 32 are arranged in a staggered pattern. Although the positional relationship of the layers of the connection conductor 33 and the position of the wraparound portion 33b are changed due to the change of the arrangement of the terminal pieces 32, the arrangement is basically the same as that shown in FIG. Further, the terminal piece 32 with respect to the arrangement order of the contacts 31
The arrangement order of is similar to that shown in FIG. Here, the connecting conductor 33 has a step portion 33 near the terminal piece 32.
c is formed, and most of the intermediate portion of the connection conductor 33 is an upper layer. Thus, the connecting conductor 33 is an upper layer, the middle layer is a lower layer, and the wrap-around portion 33a formed at the front end portion of the connecting conductor 33 is also in the same layer so that the connecting conductor 33 has a step also at the front end portion. The portion 33d is formed.

The conductor 30 is not limited to the one formed by punching a sheet metal, and as shown in FIG. 45, the portion excluding the terminal piece 32 can be formed by a wire. Further, as shown in FIG. 46, it is possible to use only the contact 31 as a wire rod and form the terminal piece 32 and the connection conductor 33 by sheet metal. 45 and 46, the portions having the same reference numerals as those in FIG. 44 have the same function.

In the conductor 30 described above, the connection conductors 33 are arranged in three layers, but it is also possible to form a pattern in which the connection conductors 33 are arranged in one plane while reducing the amount of crosstalk. In such a pattern, as shown in FIGS. 47 and 48, the printed circuit board 34 is used and the printed circuit board 3 is used.
The conductive pattern formed in 4 can be used as the connection conductor 33. The contact 31 and the terminal piece 32 are mounted on the printed board 34. The terminal piece 32 is coupled and held to the insert body 20 as described above, but the contact 31 is not coupled to the insert body 20 and the printed circuit board 34.
It is easy to bend just by fixing it to the solder. Therefore, a support 35 made of a synthetic resin that supports the base of the contact 31 is provided to integrate the plurality of contacts 31. This support 35 increases the support strength of the contact 31 and prevents the contact 31 from wobbling.

In each of the conductors 30 described above, the contact 31 is extended obliquely rearward from the tip of the connecting conductor 33. However, as shown in FIG. The conductor 30 may be formed so as to extend obliquely forward from the tip portion. In this way, by reversing the directions of the currents flowing through some of the contacts 31, the crosstalk current can be made in a phase opposite to that of the modular plug, and as a result, the crosstalk currents cancel each other and the crosstalk amount is reduced. is there.

Although the above-mentioned connecting conductors 33 do not vertically intersect, it is possible to adopt a configuration in which a part of them cross vertically as a configuration for reducing the crosstalk amount. The terminal piece 32 receives a pressing force when the electric wire 2 is press-fitted into the pressure contact slit 32a, and at this time, a force other than a component orthogonal to the thickness direction of the terminal piece 32 may act. The terminal piece 32 may be reinforced to prevent deformation. For example, as shown in FIG. 50, the deformation restricting ribs 36 having a U-shaped cross section are provided upright at the portions of the insert 20 corresponding to both sides of the terminal piece 32. The deformation restricting rib 36 is provided at a position that does not hinder the press-fitting of the electric wire 2 into the press contact slit 32a, and reinforces the terminal piece 32 so that the terminal piece 32 is not deformed even when a component force in the thickness direction acts on the terminal piece 32. The deformation regulating rib 36 may be provided on the fixture 40 side instead of the housing side.

By the way, in the above-mentioned basic embodiment,
Although the pressing rib 47 is projectingly provided on the fixture 40, the pressing rib 55 may be projectingly provided on the lever 50 as shown in FIG. In this case, the fixing rib 40 does not need the pressing rib 47. In short, the pressing ribs 47 and 55 may be provided on one of the fixture 40 and the lever 50. In any of the above-described configurations, the fixture 40 moves downward when the lever 50 is tilted, but a tool such as a flat-blade screwdriver is required to raise the fixture 40. There is a configuration as shown in FIG. 52 in which the fixture 40 can be moved upward by the lever 50. In this configuration, the fixture 40 and the lever 50 are connected via the link 56, and the link 56 is rotatably attached to the side faces of the fixture 40 and the lever 50, respectively. . The length and the connecting position of the link 56 are the same as those of the rotating shaft 51.
It is set so that the fixture 40 can be moved up and down when the lever 50 rotates around the center. Therefore, if the lever 50 is tilted down, the fixture 40 can be moved downward to press the electric wire 2 into the terminal piece 32. If the lever 50 is raised, the fixture 40 can be moved upward to move the electric wire 2 from the terminal piece 32. It can be pulled out.

Although the number of levers 50 is two in the above configuration example, three or more levers may be used in some cases, and one lever 50 may be provided as shown in FIG. Similarly, the number of fixtures 40 may be three or more, and may be one. Furthermore, the number of levers 50 and the number of lake bottoms 40 do not necessarily have to match.
