Abstract

PROBLEM TO BE SOLVED: To provide a compact electric connector applicable for high speed transmission at about 100 MHz and capable of suppressing crosstalk. SOLUTION: Terminals 1 are arranged on two straight lines L1, L2 six by six and each pair consisting of neighboring terminals arranged on the different straight lines L1, L2 constitutes a transmission and reception pair 2. The distance (a) between the terminals of each pair constituting the transmission and reception pair 2 is set shorter than the distance (b) between neighboring transmission and reception pairs.

[0002]

2. Description of the Related Art It is generally known that, in an adjacent signal transmission line, a signal current of one circuit causes a current to flow in the other circuit by capacitive coupling or electromagnetic coupling, thereby causing crosstalk. Crosstalk increases as the frequency of the signal current increases (that is, as the transmission speed increases), and if significant crosstalk occurs, the signal will not be transmitted properly. Therefore, reducing crosstalk is an important issue.

The distance between the pair of terminals is set smaller than the distance between the other terminals. According to this configuration, the coupling between each pair of terminals forming the terminal set is strengthened, and is less likely to be affected by the outside.

Are arranged at an intermediate position between each pair of terminals of the terminal set orthogonal to the above. According to this configuration, since the pair of terminals forming each terminal set are alternately arranged in different directions, the difference in distance between each terminal forming the other terminal set and one terminal of the adjacent terminal set is determined. (Ie, the distance from each terminal of the other terminal set to the terminal of the one terminal set becomes substantially equal), and the effect of each terminal is canceled between adjacent terminal sets, and crosstalk is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments described below relate to a technique for reducing crosstalk at terminals of a connector. In the following embodiment, six pairs of transmission / reception pairs (terminal sets) are provided, but the number of transmission / reception pairs is not limited to this. (Embodiment 1) In this embodiment, as shown in FIG. 1, six terminals 1 are arranged on two parallel straight lines L1 and L2, and are arranged on different straight lines L1 and L2 so as to be adjacent to each other. Each pair of terminals 1 forms a transmission / reception pair (terminal set) 2. That is, the center of the transmission / reception pair 2 is arranged on one reference line (not shown). In FIG. 1, each pair of terminals 1 surrounded by a dashed line forms a transmission / reception pair 2. Each pair of terminals 1 forming each transmission / reception pair 2 is arranged on a straight line in a direction (vertical direction in FIG. 1) orthogonal to the straight lines L1 and L2. Each terminal 1 is connected to the straight line L1, L
2 (a left-right direction in FIG. 1) is formed in a rectangular cross section longer than the up-down direction. In addition, send / receive pair 2
Are arranged at equal intervals along the straight lines L1 and L2.

Here, in order to reduce crosstalk, the distance a between each pair of terminals 1 forming each transmission / reception pair 2 is set smaller than the distance b between adjacent transmission / reception pairs 2 (terminals). (The distances A and B between the centers of the 1 are also smaller in the vertical direction than in the horizontal direction.) By setting such a dimensional relationship, the distance between each pair of terminals 1 forming each transmission / reception pair 2 becomes smaller than the distance between the terminals 1 forming another transmission / reception pair 2, and consequently other distances. The amount of signal current leakage to the transmission / reception pair 2 is reduced.

(Embodiment 2) As shown in FIG. 2, this embodiment has a transmission / reception pair 2 similar to that of the embodiment 1, but each pair of terminals 1 forming each transmission / reception pair 2 Are different from the first embodiment in that three are arranged on four straight lines L11 to L14 parallel to each other. That is, in the present embodiment, the center of each transmission / reception pair 2 has two reference lines (not shown).
Is placed on one of the. Now, straight lines L11 to L11
Assuming that L14 is arranged from the top in FIG. 2, terminal 1 is arranged on the straight lines L11 and L13 in the transmission / reception pair 2 at the left end, and the transmission / reception pair 2 from the left is located on the straight lines L12 and L1.
4 is located on top of the third transmission / reception pair 2 from the left.
The terminal 1 is arranged on the straight lines L11 and L13. The four straight lines L11 to L14 are set at equal intervals. Further, the transmission / reception pairs 2 are set at equal intervals in the left-right direction in FIG.

The pair of terminals 1 forming the transmission / reception pair 2 are arranged in a direction (vertical direction in FIG. 2) orthogonal to the straight lines L11 to L14, as in the first embodiment. However, as described above, the adjacent transmission / reception pairs 2 are vertically offset from each other, and the other transmission / reception pair is located at an intermediate position in the vertical direction between each pair of terminals 1 forming one of the adjacent pair of transmission / reception pairs 2. The two terminals 1 of the pair 2 are arranged so as to be located in a staggered arrangement. By adopting such an arrangement, assuming that the width in the left-right direction is equal to that of the first embodiment, the distance between the adjacent transmission / reception pairs 2 can be larger than that of the first embodiment. It becomes possible to reduce.

In the above arrangement, straight lines L12 and L13
Are arranged so that the influence from the surrounding other terminals 1 or the influence on the other terminals 1 is equal. Another configuration is the first embodiment.
Is the same as (Embodiment 3) In the present embodiment, as shown in FIG. 3, the transmission / reception pair 2 similar to that of the first embodiment is used, and the center of the transmission / reception pair 2 is arranged on a horizontal straight line (reference line) L0. (The center of each transmitting / receiving pair 2 is on a straight line). However, in each pair of adjacent transmission / reception pairs 2, straight lines passing through each pair of terminals 1 forming the transmission / reception pair 2 are orthogonal to each other. In other words, if one pair of the transmitting and receiving pairs 2 adjacent to each other has a pair of terminals 1 arranged vertically in FIG. 3, the other pair of terminals 1 is arranged horizontally in FIG. 3. It is. The transmission / reception pair 2 in which the pair of terminals 1 are disposed in the left-right direction is located on a straight line L0 passing through the center of each transmission / reception pair 2 in which the pair of terminals 1 is disposed in the vertical direction. The distance from the arranged pair of terminals 1 to each terminal 1 arranged in the left-right direction is equal. Therefore, when the pair of terminals 1 forming the transmission / reception pair 2 are arranged in the left-right direction, the influence from the surrounding other terminals 1 and the influence on the other terminals 1 are substantially equal. Other configurations are the same as in the first embodiment.

(Embodiment 4) In this embodiment, as shown in FIG. 4, a pair of terminals 1 forming a transmission / reception pair 2 are arranged six on each of two parallel straight lines L1 and L2. This is the same as the first embodiment in this point, but differs from the first embodiment in that a transmission / reception pair 2 is formed on each of the straight lines L1 and L2. That is, three transmission / reception pairs 2 are arranged on each of the straight lines L1 and L2. Terminal 1
As in the first embodiment, the cross-sectional shape is formed in a rectangular shape that is long in the left-right direction, and a pair of left and right terminals 1 forms a transmission / reception pair 2. Further, the transmission / reception pair 2 on each of the straight lines L1 and L2 is arranged on a vertical line (that is, the transmission / reception pair 2 is placed on the vertical line passing through the center of each transmission / reception pair 2 on one of the straight lines L1 and the other). The transmission / reception pair 2 is located on the straight line L2 of FIG.

Here, the distance A between each pair of terminals 1 forming each transmission / reception pair 2 is set smaller than the distances B and C from the terminals 1 forming the other transmission / reception pairs 2. Therefore, crosstalk is reduced as in the first embodiment. In the case of the present embodiment, if the number of the transmission / reception pairs 2 is not an even number, one transmission / reception pair 2 has a pair of terminals 1 arranged vertically, and the center of the transmission / reception pair 2 is the center of the straight lines L1 and L2. Arrange so that it is located in the middle. Other configurations are the same as in the first embodiment.

(Embodiment 5) In this embodiment, as shown in FIG. 5, similar to Embodiment 4, two parallel straight lines L
1 and L2, each terminal 1 is arranged, and each straight line L1, L2
And three transmission / reception pairs 2 are arranged on each of the transmission / reception pairs. However, the transmission / reception pairs 2 on the other straight line L2 are arranged in a zigzag manner such that the transmission / reception pairs 2 on the other straight line L2 are arranged at positions corresponding to between a pair of adjacent transmission / reception pairs 2 on one straight line L1. It is. With this configuration, the distance between the terminals 1 where the transmitting / receiving pair 2 is not formed is larger than in the fourth embodiment, and the crosstalk is further reduced. Other configurations are the same as those of the fourth embodiment.

(Embodiment 6) In this embodiment, as shown in FIG. 6, an electric connector for connecting two twisted pair cables 3 as external electric wires, and an electric wire drawn from a sheath 3a of the twisted pair cable 3 A cable holding portion 4 for holding the wires 3b so as to be substantially parallel, a contact 5 electrically connected to an electric connector on the other side, and an electric wire 3b connected to the contact 5 to electrically connect the electric wire 3b and the contact 5 to each other. And a terminating portion 6 which is electrically connected. The termination portion 6 may be of any type. For example, the wire 3b insulated from the slit provided in the terminal piece is provided.
Is press-fitted along the slit to cut the insulating coating so as to simultaneously hold and connect the electric wire 3b to the terminal piece. There are various types of contact portions of the contacts 5 provided on the other connector. For example, one contact is made of a plate material, such as a modular jack and a modular plug.
It is possible to adopt a configuration in which the other contact is a wire spring that elastically contacts the plate material.

Incidentally, in order to connect the electric wire 3b of the twisted pair cable 3 to the contact 5, the twist of the electric wire 3b must be unwound, and there is a possibility that crosstalk will increase in this portion. Therefore, in the present embodiment, the electric wires 3 arranged substantially in parallel in the cable holding portion 4 are provided.
By crossing a part of b (the crossing site is indicated by 3c), an increase in crosstalk is suppressed. Specifically, the electric wires 3b forming each pair are arranged in order on the cable holding portion 4, and one of the adjacent pairs crosses and the other is kept parallel to be connected to the termination portion 6. It is. The pairs where the wires 3b cross each other are crossed once in each electrical connector. In other words, the electric wires 3b are arranged side by side on the cable holding part 4 (FIG. 6 is arranged in the vertical direction), and the electric wires 3b forming a pair are arranged so as to be adjacent to each other. Here, in each electrical connector, pairs in which the wires 3b intersect and pairs 3b in which the wires 3b do not intersect are alternately arranged. In the pair where the wires 3b cross each other, there are two crossing portions 3c between the twisted pair cables 3 connected to each other. Therefore, in the above configuration, the arrangement of the wires 3b in the two connectors is reversed but the order is not changed.

With the above-mentioned structure, if the pairs are equal except for the condition of whether or not the wires 3b are to be crossed (replaced), when the lengths of the parallel portions before and after the crossing become equal, the crosstalk is reduced. It becomes the smallest. However, the position and the number of times at which the electric wires 3b cross each other are not limited to those described above. The arrangement of the terminals 1 in this embodiment is the same as that of the fourth embodiment, but is not limited to this.

(Embodiment 7) In the present embodiment shown in FIG. 7, the thickness direction of the cable holding portion 4 (FIG.
The electric wires 3b (in the vertical direction of (b)) are in pairs. In the present embodiment, each pair of wires 3b intersects only one of the two electrical connectors (the intersection is indicated by 3c). In addition, each adjacent pair (corresponding to the transmission / reception pair 2 of the first embodiment) has a different intersection portion 3c. In the illustrated example, the electrical connectors that form the intersecting portions 3c are different between adjacent pairs. The number and positions of the intersections 3c are not limited to those shown in FIG. The arrangement of the terminals 1 in the present embodiment is the same as that of the first embodiment, but is not limited to this.

(Embodiment 8) In the present embodiment, as shown in FIG. 8, the number of crossings of the electric wire 3b forming a pair is different for each pair. That is, the electric wires 3b are arranged in the same manner as the terminals 1 of the fourth embodiment, and each pair of electric wires 3b arranged in the left and right direction (up and down in FIG. 8) is arranged so as to form a pair.
Here, in the upper pair shown in FIG. 8, the electric wires 3b cross each once in the cable holding portion 4 of each connector, the middle pair does not cross the electric wires 3b, and the lower pair does not cross the electric wires 3b but the contacts 5 instead. Are crossed (the crossing site is indicated by 3c). In this way, by making the number of crossings different for each pair, it is difficult for not only adjacent pairs but also other pairs to be coupled. That is, crosstalk can be further reduced. Moreover, in the present embodiment, the position of the intersection part 3c is different for each pair, and this point is also effective in reducing crosstalk. The position and the number of the intersections 3c are appropriately selected. The same arrangement as that of the fourth embodiment is employed as the arrangement of the electric wires 3b, but the arrangement is not particularly limited.

(Ninth Embodiment 9) In this embodiment, as shown in FIG. 9, a reverse-phase current generating portion which is extended in a substantially U-shape at one end of a contact 5 provided on each connector and in contact with each other. 5a. By forming the reverse-phase current generating portion 5a as shown in FIG. 9B, the signal current leaked from another adjacent pair of contacts 5 (the upper contact 5 in FIG. 9
(B) the current flowing to the other part of the contact 5) below;
Since the current flowing in the negative-phase current generator 5a is in reverse phase, if the position, size, and shape of the negative-phase current generator 5a are appropriately adjusted, the leakage current can be canceled and crosstalk can be reduced. . In this embodiment, the arrangement of the electric wires 3b is the same as that of the terminal 1 of the fourth embodiment, but another arrangement may be adopted.

(Embodiment 10) In this embodiment, as shown in FIG. 10, a capacitance adding member 8 is embedded in a contact holding member 7 which is an insulating substrate holding the contact 5. The contacts 5 are arranged on the front and back of the contact holding member 7, and in the present embodiment, the contacts 5 on the front and back of the contact holding member 7 are paired as in the first embodiment. The capacitance adding member 8 is formed of a metal plate, is buried in the contact holding member 7, and is arranged so as to straddle between the contacts 5 arranged on different surfaces on the front and back of the adjacent pair of contacts 5. . However, each end of the capacitance adding member 8 and the contact 5 face each other via an insulating layer. Therefore, a capacitance component is formed between the contact 5 and the capacitance addition member 8, and the capacitance component between the adjacent pair of contacts 5 arranged on different surfaces on the front and back of the contact holding member 7 is converted to the capacitance addition member 8. Can be adjusted. Here, two capacitance adding members 8 are provided for each pair of adjacent contacts 5. That is, one capacitance adding member 8 is arranged between one pair of contacts 5 arranged on one surface of the contact holding member 7 and the other pair of contacts 5 arranged on the other surface of the contact holding member 7, Another capacitance adding member 8 is provided between the one pair of contacts 5 arranged on the other surface of the contact holding member 7 and the other pair of contacts 5 arranged on the one surface of the contact holding member 7. Be placed. Therefore, it is possible to adjust the capacitance components at the positions shown as capacitors C1 and C2 in FIG.

If the capacitance component generated by the capacitance adding member 8 is set to an appropriate value, the capacitance between each pair of terminals 1 forming the transmission / reception pair 2 and the capacitance between the capacitors C1 and C1 in FIG.
The capacitance component indicated as C2 becomes equal. As a result, if one transmitting / receiving pair 2 is regarded as a signal source and the voltage generated in the other transmitting / receiving pair 2 is considered, the bridge circuit with the above-described capacitance can be balanced, and the other transmitting / receiving pair 2 No voltage is generated by the signal of the one transmission / reception pair 2, and therefore, crosstalk due to electrostatic coupling can be suppressed. In the present embodiment, the contacts 5 are arranged in the same manner as the terminals 1 of the first embodiment, but another arrangement may be adopted. It is needless to say that the above embodiments may be appropriately combined.

[0030]

According to the structure of the present invention, crosstalk can be reduced without shielding between pairs.
As a result, there is an effect that it is possible to provide a small-sized electrical connector having sufficient performance for application to high-speed transmission of about 100 MHz.
