Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mainly used for signal transmission for preventing crosstalk.

[0002]

2. Description of the Related Art In recent years, in the field of telecommunications, the amount of information to be transmitted has been dramatically increased, so that high-speed signal transmission is required. Since high-speed transmission requires the use of high-frequency signals, the amount of crosstalk between signal lines due to electrostatic coupling increases. That is, it is necessary to reduce the amount of crosstalk in order to prevent signal quality deterioration, and to perform high-speed signal transmission, it is necessary to prevent crosstalk not only in signal lines but also in connectors. Is done.

A connector generally used for communication has a configuration in which two connectors (plug and jack) are connected to each other, and an output terminal connected to the other and an input terminal connected to an external electric wire (signal line). A connection conductor portion for internally connecting the output terminal and the input terminal is formed of a conductor, and these conductors include portions arranged in parallel in one plane. In such a parallel portion, crosstalk current flows because the capacitance components between conductors transmitting other signals become unbalanced. In addition, since the assignment and the positional relationship of the signal types are fixedly determined for the output terminals according to the standard, there is a problem that the degree of freedom of design is low and it is difficult to reduce the crosstalk at the output terminals.

In this type of connector, a conductor structure has been devised so as to reduce crosstalk between input terminals of the plug and the jack in a state where the plug and the jack are connected to each other. In this case, the connector on the plug side is smaller in size than the connector on the jack side, and there is little room for devising the conductor structure. Therefore, in order to improve the crosstalk characteristics, the arrangement of the connection conductor in the connector on the jack side is devised. It is common. Also, as described above, the output terminals are restricted in arrangement, and the input terminals also have a low degree of freedom in arrangement. Therefore, attempts have been made to reduce crosstalk by devising the arrangement of conductors forming the connection conductor. It has been done. In addition, such a connection conductor is often constituted by a conductor manufactured by punching a substrate pattern or a wire frame.

[0005]

By the way, if many types of signal lines are to be connected by one connector, it is desirable to arrange the connecting conductors so as to prevent crosstalk between all the signal lines. In addition, there is a problem that the design or manufacture of the arrangement of the connection conductors becomes complicated. Further, in the conventional example, since the specific gravity is given to the prevention of crosstalk and the arrangement of the output terminals is fixedly determined according to the standard, the arrangement of the input terminals connected to the signal lines is largely considered. Was not done,
When the signal line is a pair line, the input terminals of each pair may not be arranged adjacently, and there is a problem that the workability is low because the arrangement is not easy to construct.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a connector that reduces crosstalk and that is easy to manufacture and easy to install.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIGS. Although the present embodiment exemplifies a modular jack as a connector, it does not prevent the technical idea of the present invention from being applied to other types of connectors. As shown in FIG. 5, the modular jack of the present embodiment is of an eight-pole type and includes a body 10 made of a synthetic resin molded product (dielectric) as an insulating material and a housing made of an insert 20. Holds the conductor 30 that electrically connects the output terminal 31 and the input terminal 32 via the connection conductor 33.

The body 10 includes a connection base 11 having a plug insertion opening 13 into which a modular plug is inserted, which is opened at the front, and a base 12 extending rearward from a lower rear portion of the connection base 11 in a continuous and integral manner. The connection base 11 is formed in a hollow shape, and a mounting hole 14 into which the insertion body 20 is inserted is opened at a lower portion of the rear wall. In addition, a comb-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 includes a base 20a having an output terminal support 21 for holding an output terminal 31 at a front end thereof, and a pair of terminal bases projecting from an upper surface of the base 20a and projecting an input terminal 32 upward. 22 ₁ and 22 ₂ . An output terminal support 21 is provided on the upper surface near the front end of the base 20a.
And a pair of bearing bases 2 in a form of partitioning the terminal bases 22 ₁ and 22 _{2 from} each other.
3 _1, 23 ₂ are projected.

By the way, the wiring assignment of the output terminal 21 is as follows.
ANSI / EIA / TIA-568 (Commercial Building Communication Wiring Standard), as shown in FIG.
When 0 is viewed from the lower surface, terminal numbers are assigned in the order of from top to bottom. At this time, the color code of the electric wire electrically connected to each of the output terminals 21 is defined as follows. That is, white-orange, orange, white-green,
Blue, white-blue, green, white-brown, brown (white-X
(X: orange, green, blue, brown) indicates white and X
And that the two colors are colored over the entire length). Further, the electric wire 2 connected to the input terminal 32 is a twisted pair wire, and the connection relationship is defined such that the pair of the output terminals 21 are paired. In other words, the paired wire of the twisted pair wire is obtained by twisting a color wire having a single color of the insulation coating and a white background wire having the two colors of the insulation coating of white and other colors. The colors that are not the same as the colors of the paired color lines are adopted. For example, when the white background line is two colors of white and green, the color line is paired with green. In addition to the color code of such wires, the near-end crosstalk between pairs of wires is also specified.

Here, since the pair is arranged between the pairs, the bridge circuit formed by the capacitance component between the connection conductors 33 becomes unbalanced.
That is, a crosstalk current easily flows between the pair and the crosstalk current increases particularly when the frequency of the signal increases. Also, as for the other pairs, the higher the frequency, the more the amount of crosstalk increases.

On the other hand, in reducing the above-mentioned crosstalk amount, considering the simplicity of connection, the cost, the degree of spread, and the like,
It is desirable to use the modular jacks and modular plugs currently used without changing the structure. Therefore, in the present invention, the connection conductor portion 33 of the conductor 30 is provided.
Are arranged in one plane with respect to the insertion body 20, and a positional relationship is set such that the amount of crosstalk between the twisted pair wires is reduced by adjusting the width of the connecting conductors 33 and the distance between them. is there. In particular, as described later, the output terminal 31
In the state where 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 by appropriately changing the arrangement order in the left-right direction between the connection conductor 33 and the connection conductor 33. This causes the unbalanced currents of both to cancel each other, thereby reducing the amount of crosstalk. In addition, by arranging the connection conductors 33 in one plane, it is possible to suppress variations in transmission performance (including crosstalk) due to variations during manufacturing, and to improve ease of manufacturing and workability. There is also an advantage that can be.

Here, each of the conductors 30 including the output terminal 21, the input terminal 32, and the connection conductor 33 has an elasticity.
A metal plate (alloy) having a thickness of about 4 mm is punched out to be continuously and integrally formed in a lead frame shape, and a plurality of conductors 30 are formed by punching one metal plate. The metal plate can be continuously punched by supplying it as a hoop material as in the case of forming a lead frame for an integrated circuit.

The conductor 30 punched and formed into the shape described above is mounted on the insert 20. As shown in FIG. 1, the connecting conductor 33 of the conductor 30 is
The base 20a is disposed in a recess 20b provided in the base 20a, and an opening surface of the recess 20b is closed by a flat lid 27. The output terminal 21 is bent after forming the insert 20. As described above, since the bending work is hardly required, the working becomes easy. Here, the pattern of each conductor 30 is formed in a shape such that it does not cross three-dimensionally when the output terminal 21 and the input terminal 32 are bent by being attached to the insert 20 (see FIGS. 3 and 4). Therefore, there is no need to consider the mounting order when mounting each conductor 30 to the insert 20. In addition, each pair of connecting conductors 3
Since the positional relationship is such that the capacitance components between the three components are substantially balanced, it is possible to reduce the amount of crosstalk. Further, since the left and right sides of the output terminal 21 and the connection conductor 33 are reversed for each pair of
In each of these pairs, the relationship between the left and right arrangement of the contact portions of the modular plug, which is the mating connector contacting the output terminal 21, and the left and right arrangement of the connection conductor portions 33 can be reversed. As a result, when the modular jack of the present invention is connected to the modular plug, an unbalanced current having a phase opposite to that of the unbalanced current generated in the modular plug is generated in the modular jack, and the unbalanced currents of the two cancel each other. Crosstalk is further reduced. If the plurality of conductors 30 are insert-molded into the insert 20, the manufacturing process can be simplified.

In the above-mentioned pair, the connection conductors 33 are adjacent to each other, so that the input terminals 32 can also be adjacent to each other.
The input terminals 32 are arranged next to each other by forming a wraparound portion 34 in the connection conductor portion 33 because there is a pair of connection conductor portions 33 between them (see FIG. 2). That is, the wraparound portion 34 is formed so as to pass through the opposite side of the output terminal 21 with respect to the other pair of input terminals 32, so that the pair of input terminals 32 can be adjacent to each other. I can do it. Also, the input terminal 32
Are arranged in such an order that the color lines and the white background lines of the connected pair lines are alternately arranged. With such an arrangement, a pair of color lines and a white background line are connected to the adjacent input terminal 32, and the color lines and the white background line are alternately arranged. It can be easily recognized, and as a result, erroneous connection can be reduced. This leads to an improvement in the reliability of the construction.
In addition, since the left and right in FIG. 2 are interchangeable, the wraparound portion 34 may be provided in the connection conductor portion 33.

The insert 20 is bearing stand 23 _1, 23 ₂ of the front surface of the insert 20 is inserted comes into contact with the rear surface of the connecting base 11 into position, insert 20 is positioned with respect to the body 10 ( (See FIG. 7). That is, the front surface of the bearing stand 23 _1, 23 ₂ functions to regulate the insertion amount with respect to the body 10 of the insert 20. The output terminal support 21 is provided with an output terminal 31 protruding from the front end toward the rear upper side. When the output terminal support 21 of the insert 20 is inserted into the connection base 11 of the body 10, each output terminal is provided. 31 are respectively introduced into the separation slits 15. Bearing stand 2 of insert 20
3 _1, 23 ₂ is a rear end portion of the output terminal 31 in contact with a position on the rear surface of the connecting base 11 is kept inserted in the separation slit 15 is prevented from contacting with each other the output terminal 31 . By inserting the output terminal 31 into the connection base 11 in this manner, the output terminal 31 can elastically contact the contact (contact portion) of the modular plug inserted into the connection base 11 through the plug insertion port 13. It is.

In this state, the retaining projections 21c provided on both sides of the rear portion of the output terminal support 21 of the insertion body 20 engage with the retaining holes 11c provided on both sides of the rear portion of the connecting base 11, so that the body 10 is secured. And the insert 20 are fixed. In other words, the retaining projection 21c and the retaining hole 11c function as coupling means for coupling the body 10 and the insert 20.

As described above, the engaging ridge 2 is inserted into the engaging groove 11a.
1a is with the mounting hole 14 engages the output terminal support base 21 engage, the connecting base 11 from pedestal 23 _1, 23 ₂ abuts, the body 10 and the insert 20 is positioned to one another You. Moreover, when the insert 20 is inserted into the body 10 to a predetermined position, the retaining projection 21c is
c, the insert 20 is fixed in place with respect to the body 10. Further, the rear part of the insert 20 is placed on the base 12 with the insert 20 being coupled to the body 10.

C), which is formed in a fork shape having a pressure contact slit 32a having an open upper end edge between a pair of teeth, and the width of the pressure contact slit 32a is set to be equal to that of the core wire of the electric wire 2 to be connected.
It is set so that both side edges of 2a are pressed against each other. That is, when the electric wire 2 having the insulating coating is press-fitted into the press-fitting slit 32a from above, the insulating coating of the electric wire 2 is applied to the press-fitting slit 3a.
The core wire of the electric wire 2 is introduced into the press-contact slit 32a while stripping the insulating coating by cutting at both side edges of 2a, and the core wire is sandwiched between both side edges of the press-contact slit 32a.

In the input terminal 32, it is necessary to cut off the insulating coating of the electric wire 2 at both side edges of the press-contact slit 32a. Therefore, it is desirable to make the tip of the input terminal 32 thinner than other portions. That is, if the tip of the input terminal 32 has the above-described shape, the insulating coating of the electric wire 2 can be more easily cut off,
As a result, the force required for press-fitting the electric wire 2 into the input terminal 32 is reduced.
