Electrical connector

The present invention relates to an electrical connector, and in particular to an electrical connector suitable for high speed transmission (eg, 12.5 Gbps).

The conventional PCI (Peripheral Component Interconnect) connector has many areas for improvement in terms of transmission rate improvement. For example, a TCA (Telecom Computing Architecture) connector in a PCI connector includes a plurality of pairs of signal chips and a plurality of grounding strips, and the pair of signal chips and the grounding strip are staggered so that each signal chip A grounding piece is arranged next to the grounding piece to shield the signal piece to reduce the possibility of signal interference.

The conventional signal chip included in the TCA connector has a rubber core, a fixing section embedded in the rubber core, and a matching section and a fisheye section respectively extending from opposite ends of the fixing section. The width of the fixed section and the connected mating section are substantially the same, and the dielectric constant of the rubber core coated on the outer surface of the fixing section is obviously different from the dielectric constant of the air coated on the outer surface of the mating section. This causes impedance inconsistency, which is not conducive to further increase the transmission rate of the TCA connector.

In summary, the electrical connector provided by the present embodiment has a lower dielectric constant than the coated first region due to the medium (eg, air) that is not contacted by the rubber-coated portion. The dielectric constant of the rubber core contacted by the segment, so that the first portion covered by the rubber core is tapered, so that the impedance of the first segment and its associated mating segment can be adjusted to be substantially the same, thereby facilitating the lifting.

Please refer to FIG. 1 to FIG. 11 , which is an embodiment of the creation. It should be noted that the related quantity and appearance mentioned in the embodiment are only used to specifically describe the implementation of the creation. Ways to understand the content, not to limit the scope of the creation. The present embodiment provides an electrical connector 100 that is suitable for high-speed transmission (eg, a transmission rate of preferably 12.5 Gbps), and the type of the electrical connector 100 is suitable for plug-in boards in this embodiment. The TCA connector is taken as an example, but the type of the electrical connector 100 of the present invention is not limited thereto.

Referring to FIG. 1 to FIG. 3A , the electrical connector 100 includes an elongated insulating body 1 , a pair of differential signal chips 2 , a plurality of grounding shields 3 , and a series of connectors 4 . The insulative housing 1 defines a longitudinal direction L, a width direction W, and a height direction H that are perpendicular to each other. The differential signal chip 2 and the grounding shield 3 are inserted into the insulative housing 1 and arranged in a row along the length direction L, and a pair of differential signal plates 2 are disposed between any two adjacent grounding shields 3. And each pair of differential signal chips is located at the signal transmission portion of the insulative housing 1 (ie, the fixed segment 221 and the mating segment 222 as described below) in the length direction. It is completely shielded from the grounding shield 3 adjacent to it by L. It should be explained that the "complete" masking of this embodiment means that when viewed in a specific direction, the object to be shielded cannot be seen.

Referring to FIG. 4 to FIG. 6 , the configurations of the pair of differential signal chips 2 are substantially the same. Therefore, only one pair of differential signal chips 2 and their adjacent ground shielding plates 3 are illustrated in FIG. 4 , and only FIG. Among them, a pair of differential signal chips 2, only one of the differential signal chips 2 is illustrated in Fig. 6, for the purpose of explaining the configuration thereof.

As shown in FIG. 6, each differential signal chip 2 includes a sheet-shaped rubber core 21 and two long-shaped signal terminals 22, and each signal terminal 22 has a fixed section 221 embedded in the rubber core 21, and The opposite ends of the fixing section 221 (such as the top end and the bottom end of the fixing section 221 in FIG. 6) respectively extend in a direction substantially away from each other to protrude from a mating section 222 of the rubber core 21 and a positioning section 223.

The fixing section 221 and the mating section 222 of each of the differential signal sheets 2 are substantially received in the insulative housing 1 , and the positioning section 223 of each differential signal strip 2 is inserted into the insulative housing 1 and exposed. Outside the insulating body 1 (see Figure 2). It should be noted that the outer surface of the fixed section 221 and the mating section 222 of the signal terminal 22 can be roughly divided into two wide surfaces perpendicular to the longitudinal direction L and a narrow surface surrounding the outer edges of the two wide surfaces.

In more detail, in each of the signal terminals 22, the fixed section 221 has a continuous strip-shaped first section 2211 and a curved second section 2212, and is away from the second section 2212. One end of a section 2211 (such as the top end of the first section 2211 in FIG. 6) is connected to the mating section 222, and away from the end of the second section 2212 of the first section 2211 (such as the bottom of the second section 2212 in FIG. 6). The end is then connected to the positioning segment 223.

Wherein, in the width direction W, the width of the first segment 2211 of the fixed segment 221 of each signal terminal 22 is smaller than the portion of the mating segment 222 to which it is connected (as in FIG. 6). The width of the bottom portion of the section 222 is matched. The above design considerations are: the portion of the mating segment 222 that is not covered by the rubber core 21, and the dielectric (eg, air) that it contacts has a lower dielectric constant than the rubber core 21 that the coated first segment 2211 contacts. The dielectric constant, so that the first section 2211 covered by the rubber core 21 is tapered, so that the impedance of the first section 2211 and its associated mating section 222 can be adjusted to be substantially the same, thereby facilitating the increase of the transmission rate. .

As shown in FIG. 4 and FIG. 5, in the length direction L, the first segment 2211 of any one of the differential signal chips 2 of each pair of differential signal chips 2 is adjacent to the first differential signal chip 2 Section 2211, the contours of the two are aligned with each other and form a wide-edge coupled arrangement. The wide-side coupling is generally described as follows: the first segment 2211 of any one of the differential signal chips 2 and the adjacent first segment 2211 of the other differential signal chip 2 are adjacent to each other. The wide surfaces face each other and are substantially parallel to each other, whereby a wide-side coupling can be formed in the longitudinal direction L when the signal is transmitted. Thereby, the coupling length between each pair of differential signal chips 2 can be effectively improved, thereby having a better coupling effect and effectively reducing the interference of noise between each pair of differential signal chips 2.

The second segments 2212 of each pair of differential signal chips 2 are respectively formed by bending and extending from the first segments 2211 to which they are connected, and the positioning segments 223 of each pair of differential signal chips 2 are arranged in a row in the width direction W. In the width direction W, the second segment 2212 of any one of the differential signal chips 2 of each pair of differential signal chips 2 and the adjacent second segment 2212 of the other differential signal chip 2 form a narrow-edge coupling arrangement. Settings. Further to say, corresponding to (6) on the height direction H, any of the signal terminal 22 of the first section 2211 is greater than the second _{height. 1} H segment height H ₂ of 2212.

It should be noted that the rubber core 21 in this embodiment does not have any pressing hole corresponding to the fixing portion 221, that is, the fixing portion 221 is completely covered in the rubber core 21 without any The part is exposed outside the rubber core 21, thereby facilitating the impedance control of the differential signal chip 2, and effectively improving the stability of the signal transmission, but the creation is not limited thereto.

As shown in FIG. 6, in each of the differential signal sheets 2, the inner edges of the two mating segments 222 adjacent to each other define a clamping opening 2221 at a shortest distance, and one end of the two engaging segments 222 away from the rubber core 21. The portion (the top end portion of the fitting portion 222 in FIG. 6) is formed with the above-described gripping opening 2221 and each is defined as a head portion 2222. Furthermore, in the length direction L (as shown in FIG. 4), the mating segments 222 of any of the differential signal chips 2 of each pair of differential signal chips 2 and the adjacent mating segments 222 of the other differential signal patch 2 are contoured to each other. Cut and form a wide-edge coupling arrangement.

The positioning segment 223 is exemplified in the present embodiment as a fish-eye configuration, and the position of each positioning segment 223 is adapted to penetrate the fisheye hole 2231 of the fisheye structure for the longitudinal direction L, that is, the The central axis of the fisheye hole 2231 of the positioning section 223 is parallel to the longitudinal direction L. However, the positioning segment 223 of the present creation is not limited to the fisheye configuration. For example, the positioning segment 223 can also form a configuration suitable for surface mount technology (SMT).

Referring to FIG. 7 to FIG. 9, the configurations of the grounding shield sheets 3 are substantially the same, and thus only one of the grounding shield sheets 3 is illustrated in FIGS. 7 to 9 as a configuration for the following description.

Each of the grounding shields 3 includes a sheet body 31, two long strip-shaped shield segments 32 extending from one end of the sheet body 31 (such as the top end of the sheet body 31 in FIG. 7), and the other end of the sheet body 31 (as shown in the figure). The bottom end of the sheet body 31 in 7) has three elongated extensions 33 extending in sequence and three grounding positioning segments 34. That is, the extending portion 33 and the grounding positioning portion 34 are located on a side of the sheet body 31 away from the two shielding segments 32 (such as the lower side of the sheet body 31 in FIG. 7), and one ends of the three extending portions 33 are respectively connected away from each other. One end of the sheet body 31 of the two shielding sections 32 (such as the bottom end of the sheet body 31 in FIG. 7), and the other ends of the three extending sections 33 are respectively connected to the three grounding positioning sections 34.

The grounding body 31 and the shielding section 32 of each of the grounding shields 3 are substantially received in the insulative housing 1. The grounding positioning section 34 of each of the grounding shields 3 is inserted into the insulative housing 1 and exposed outside the insulative housing 1 ( As shown in Figure 2). It should be noted that the grounding The outer surface of the sheet body 31 of the shielding sheet 3 and the shield segment 32 can be roughly divided into two wide surfaces perpendicular to the longitudinal direction L and a narrow surface surrounding the outer edges of the two wide surfaces.

In more detail, as shown in FIG. 4, the fixed sections 221 of each pair of differential signal sheets 2 are completely shielded by the sheet body 31 of the adjacent ground shield sheets 3 in the longitudinal direction L. In each of the grounding shields 3, the sheet body 31 has a structure without a hole, so that the fixing section 221 of the adjacent differential signal sheet 2 is completely shielded in the longitudinal direction L. Furthermore, the sheet body 31 has a substantially trapezoidal tab 311 between the two shield segments 32. When the tabs 311 are projected in the longitudinal direction L on the glue core 21 of the adjacent differential signal sheet 2, The outline of the tab 311 is located within the outline of the core 21.

The mating segments 222 of each pair of differential signal patches 2 are completely shielded by the shield segments 32 of their adjacent ground shields 3 in the length direction L. In each of the grounding shields 3 (FIG. 8), the inner edges of the two shield segments 32 adjacent to each other define a clamping opening 321 at a shortest distance, and one end of the two shielding segments 32 away from the sheet body 31. The portion (the top end portion of the shield segment 32 in FIG. 8) is formed with a grip opening 321 and each is defined as a head portion 322.

Wherein, in the plane of the vertical length direction L (as shown in FIG. 4), the area of the head portion 322 of the shield segment 32 of each grounding shield 3 is larger than the position of any adjacent signal terminal 22 (ie, the mating segment 222 of the signal terminal 22). The area of the head 2222). In this embodiment, the area of the head 322 of each shield segment 32 is substantially twice the area of any adjacent signal terminal 22 (ie, the head portion 2222 of the mating segment 222) corresponding to the plane of the vertical length direction L. The area, but the ratio of the area of the shield section 32 head 322 to the mating section 222 head 2222 is not limited thereto. Furthermore, in the plane of the vertical length direction L, the area of the portion other than the head 322 of each of the shield segments 32 is slightly larger than the position of any adjacent signal terminal 22 (ie, the head 2222 of the mating segment 222 of the signal terminal 22). The area outside the area).

Therefore, the relative shape and area of the shield section 32 of the grounding shield 3 and the mating section 222 of the adjacent differential signal patch 2 are designed, in particular, the area of the head portion 322 of the shield section 32 is larger than the head of the adjacent mating section 222. The area of the portion 2222 is such that the shielding effect of the grounding shield 3 corresponding to the differential signal chip 2 can be effectively improved, and the differential impedance fluctuation of the differential signal chip 2 can be relieved, thereby having better S parameters (eg, insertion loss, reflection). Loss, crosstalk).

Further, as shown in FIG. 8, in each of the grounding shields 3, the inner edges of the two head portions 322 adjacent to each other include a guiding side edge 323, and one end of the leading side edge 323 of the two head portions 322 (the bottom end of the guiding side edge 323 in FIG. 8) defines the clamping opening 321, and the other end of the guiding side edge 323 of the two heads 322 (such as the leading end of the guiding side edge 323 in FIG. 8). They are the end edges of the two shield segments 32, respectively. In the length direction L, the leading edge 323 of each grounding shield 3 and the edge of the adjacent signal terminal 22 are aligned with each other (see FIG. 4), thereby facilitating the guiding side of the card through the grounding shield 3. The edge 323 is guided by the edge of the adjacent signal terminal 22, and is further sandwiched between the clamping opening 321 of the grounding shield 3 and the clamping opening 2221 of the differential signal sheet 2.

As shown in FIG. 9, the opposite ends of each of the extending sections 33 are angularly connected to the sheet body 31 and the corresponding grounding positioning section 34, respectively, and the extending section 33 and its connected sheet body 31 are formed. The angle θ ₁ and the angle θ ₂ formed between the extension 33 and the grounding positioning section 34 connected thereto, and the two angles θ ₁ and θ ₂ are arranged at an internal error angle (θ ₁ = θ ₂ ), thereby Each of the grounding positioning segments 34 is spaced apart from the sheet body 31 by a plane perpendicular to the longitudinal direction L and is parallel to each other.

In this embodiment, as shown in FIG. 9, the lengths of the extensions 33 are substantially the same and parallel to the length direction L, and the extensions 33 are all located on the same side of the sheet body 31 (as shown in the figure). 9 in the lower left side of sheet body 31), so that any one of the plurality of ground shield plate 343 of the ground segment are positioned substantially in the same plane P _1, is not present in the above-described configuration creation limited thereto.

For example, all of the grounding segments 34 of any of the grounding shields 3 need not be located on the same plane, but must conform to each of the grounding segments 34 in a plane perpendicular to the length direction L to be spaced from the sheet body 31. And parallel to each other. 10 and 11, any one of the ground shield plate 3 of two adjacent ground positioning section 34 located in two distinct and mutually parallel plane P _1, P _2, and a ground shield sheet 3 away from any two the positioning section 34 is located on the ground _a same plane P.

Thereby, the grounding shielding sheet 3 is transmitted through the bending design of the extending portion 33, so that each of the grounding positioning segments 34 can be spaced apart from each other and parallel to each other in a plane perpendicular to the longitudinal direction L, thereby effectively avoiding the sheet. The body 31 generates a hole, so that the shielding effect of the grounding shield 3 corresponding to the differential signal chip 2 can be effectively improved, and the differential impedance fluctuation of the differential signal chip 2 can be relieved, thereby having better S parameters (eg, insertion loss, Reflection loss, crosstalk).

In addition, the grounding positioning segment 34 is exemplified in the present embodiment as a fisheye configuration identical to the positioning segment 223, and the position of each of the grounding positioning segments 34 is also suitable for the longitudinal direction L to penetrate the fisheye structure. The fisheye hole 341, that is, the central axis of the fisheye hole 341 of the grounding positioning section 34 is parallel to the longitudinal direction L. However, the grounding positioning section 34 of the present creation is not limited to the fisheye configuration. For example, the grounding location segment 34 can also form a configuration suitable for surface mount technology (SMT).

Referring to FIG. 3A and FIG. 4, three of the grounding positioning segments 34 of the two adjacent grounding shields 3 and the positioning segments 223 of the pair of differential signal patches 2 located between the two adjacent grounding shields 3 are shown. They are arranged in a row substantially in the width direction W. And two mutually adjacent signal terminals 22 positioning segments 223 are disposed between any two adjacent ground positioning segments 34 in the width direction W.

Further, when the electrical connector 100 uses the grounding shield 3 shown in FIG. 7, the three grounding segments 34 of any of the grounding shields 3 and the positioning segments 223 of the adjacent one of the differential signal patches 2 are along The width direction W is arranged in a row (Fig. 3A). When the electrical connector 100 adopts the grounding shield 3 shown in FIG. 10, the grounding positioning segments 34 of the two grounding shields 3 of the two adjacent grounding shields 3 located at the outer sides thereof The central grounding positioning portion 34 of the other grounding shield 3 is arranged in a row along the width direction W of the positioning segments 223 of the pair of differential signal plates 2 located between the two adjacent grounding shield sheets 3 ( Figure omitted).

Referring to FIG. 3A and FIG. 3B , the serial connector 4 is mounted in the insulative housing 1 , and the serial connector 4 is substantially located in the mating segment 222 of all the differential signal plates 2 and the shielding segment 32 of all the grounding shields 3 . One side, and the series member 4 is connected to the grounding shielding sheets 3, so that the grounding shielding sheets 3 can be electrically connected via the series members 4. Thereby, the electrical connector 100 can have a better effect in reducing crosstalk, and can effectively solve the related resonance problem.

In more detail, the series member 4 has a long sheet shape in the present embodiment and its major axis direction is substantially parallel to the longitudinal direction L, and one of the long edges of the stringing member 4 is concavely provided with a plurality of spaced numbers. The recesses 41 are located, and the distance between the adjacent two recesses 41 is substantially the distance between the adjacent two bodies 31. The two connecting blocks 42 facing each other are formed in each of the notches 41, and the distance between the two protrusions 42 in any of the notches 41 is slightly smaller than the thickness of the sheet body 31 of the grounding shield 3.

Furthermore, the series members 4 are respectively fastened to the sheet bodies 31 of the grounding shielding sheets 3 with their notches 41 such that the series members 4 and the one-piece body 31 are substantially perpendicular to each other, and each of the notches 41 The inner two projections 42 abut against the wide surface of the sheet body 31 located in the recess 41. From another point of view, the portions of the grounding shield sheets 3 connected to the series members 4 are arranged substantially in a row along the longitudinal direction L.
