<figref idrefs="S16">5</figref> a schematic illustration of the holes of the invention electrical connector according to a second embodiment.

As out <figref idrefs="S12">1</figref> to <figref idrefs="S13">2</figref> visible, is the inventive electrical connector made of a plastic inner part <figref>10</figref>. a plurality of terminal holes <figref>20</figref>, one rear plug-in part <figref>30</figref> and an iron housing <figref>40</figref>, The electrical connector is substantially as an electric Connector for a display port applied.

As out <figref idrefs="S14">3</figref>. <figref idrefs="S15">4</figref> seen is the plastic inner part <figref>10</figref> out Insulating prepared and has a plurality of terminal holes <figref>11</figref> and a plurality of holes <figref>12</figref> on. The mounting holes<figref>11</figref> are horizontally arranged and extend through the front in series and the rear side of the Art&lt;?page 3?&gt;material inner part <figref>10</figref> therethrough. The holes <figref>12</figref> are located at the upper and lower Side of the plastic inner part <figref>10</figref> arranged and communicate with the terminal holes <figref>11</figref>, Alternatively, the holes <figref>12</figref> only at the upper or lower side the plastic inner part <figref>10</figref> be arranged (not shown).

The conductive terminals <figref>20</figref> are made of metal with produced high-conductivity and are after row in the terminal holes <figref>11</figref> the plastic inner part <figref>10</figref> plugged in. The back side of the conductive terminals <figref>20</figref> protrudes from the rear of the plastic inner part <figref>10</figref> out.

The rear plug-in part <figref>30</figref> is also made of insulating material and communicates with the rear end of the inner plastic part <figref>10</figref> in Locking connection. The rear plug-in part<figref>30</figref> has a tongue portion <figref>31</figref>. a plurality of through holes <figref>32</figref> and a Plurality of terminal grooves <figref>33</figref> on. The tongue part<figref>31</figref> extends from the rear side of the rear plug member <figref>30</figref> after rear; the through holes<figref>32</figref> horizontally arranged and passing through the front and rear rows in Side of the rear plug-in part <figref>30</figref> therethrough, said horizontal Ranking the through holes <figref>32</figref> with the position the terminal holes <figref>11</figref> the plastic inner part <figref>10</figref> corresponds. The connection channels <figref>33</figref> are on the tongue part <figref>31</figref> arranged and communicate with the through holes <figref>32</figref>,

If the rear plug-in part <figref>30</figref> with the rear end of the inner plastic part <figref>10</figref> in Latching stands, extends the rear end of the conductive connections <figref>20</figref> through the through-holes <figref>32</figref> of rear plug-in part <figref>30</figref>, Extending into the connecting channels <figref>33</figref> of tongue part <figref>31</figref> and is received there.

After this the plastic inner part <figref>10</figref>, The conductive terminals <figref>20</figref> and the rear plug-in part <figref>30</figref> been assembled with each other are, the contact area of ​​the conductive terminals is <figref>20</figref> and the Air therefore increased, because the conductive connections <figref>20</figref> with the holes <figref>12</figref> of Plastic inner part <figref>10</figref> correspond. The dielectric constant the air is much lower than that of the plastic inner part <figref>10</figref>, For example, when the plastic inner part <figref>10</figref> plastic is, its dielectric constant is between 2.4 and 4, while the dielectric constant of the Air is 1.0054. Since the dielectric constant the substance in proportional relation to the capacity is the capacitance of the conductive terminals drops <figref>20</figref> With the enlargement of the contact surface of the Air. Further, the impedance of the substance is in inverse proportion to capacity, so that the impedance of the higher is, the lower the capacitance. Accordingly increases the impedance of the conductive leads <figref>20</figref> by virtue of the reduction of the capacity.

If later, the rear end of the conductive leads <figref>20</figref> With a cable (not shown) with a higher impedance is connected, then it is not a big difference between the impedances of the conductive terminals <figref>20</figref> and consist of the cable, so no dasss Unabstimmigkeit the impedances present. This is among the high-frequency transmission electrical connector, the transmitted high-frequency signal not weaken slightly and distorted.

Of Furthermore, the size of the holes of the inner plastic part is <figref>10</figref> ever adjustable according to the needs of the manufacturer. If the holes<figref>12</figref> greater are, the impedance of the conductive terminals is <figref>20</figref> accordingly elevated. In this way, the conductive connections <figref>20</figref> easily with cables of different Impedances match.

<figref idrefs="S16">5</figref> shows the second embodiment of the invention, wherein the second embodiment from the first differs, that on the upper and lower sides of the plastic inner part <figref>10</figref> each two rows of holes <figref>12</figref> are arranged so that the contact area of ​​the conductive terminals <figref>20</figref> and the air using the additional set of holes <figref>12</figref> increased is so as to increase the impedance.

After this the plastic inner part <figref>10</figref>, The conductive terminals <figref>20</figref>. the rear plug-in part <figref>30</figref> and the cable (not shown) have been assembled with each other, such as from <figref idrefs="S12">1</figref>. <figref idrefs="S13">2</figref> appreciated are the plastic inner part <figref>10</figref>, The rear plug-in part <figref>30</figref> and the front end of the cable to the iron casing <figref>40</figref> covered. The iron housing <figref>40</figref> is composed of an upper <figref>41</figref> and a lower iron housing <figref>42</figref> composed. During assembly, the upper housing is iron <figref>41</figref> from Front end of the plastic inner part <figref>10</figref> the plastic inner part <figref>10</figref> drawn; then snap the lower iron housing <figref>42</figref> from the lower part the upper iron housing <figref>41</figref> in which both sides the upper iron housing <figref>41</figref> on. Thereby the plastic inner part <figref>10</figref>, The rear plug-in part <figref>30</figref> and the front end of the cable between the upper <figref>41</figref> and the lower iron housing <figref>42</figref> wrapped.

Of Further, on the both sides of the iron housing <figref>40</figref> each one located inside ward extending decline locking disc <figref>43</figref> arranged which on the upper iron housing <figref>41</figref> or lower iron housing <figref>42</figref> can be attached. In the Invention, the decline locking disks <figref>43</figref> on the upper iron housing <figref>41</figref> appropriate. The decline locking disks<figref>43</figref> support on the rear surface of the two side walls <figref>12</figref> of Plastic inner part <figref>10</figref> from, in order to avoid that the &lt;?page 4?&gt;Plastic inner part <figref>10</figref> in the iron housing <figref>40</figref> slides, so that the plastic inner part <figref>10</figref> in the iron housing <figref>40</figref> remains stable.

The Invention has the following advantages: when the conductive connections <figref>20</figref> the plastic inner part <figref>10</figref> plugged in remain, allow the holes <figref>12</figref> of Plastic inner part <figref>10</figref> a Vergrößernung the contact surface of the conductive terminals <figref>20</figref> and the air, which leads to effective reduction of the capacitance of the conductive connections <figref>20</figref> and thereby increase the impedance the conductive terminals <figref>20</figref> contributes so that so that the impedances of the conductive terminals <figref>20</figref> and the cable coincide with each other.
