The fixing portion is fixed in the fixing hole, the through hole is located in the fixing hole, the first side faces the first inner side wall and is spaced apart from the first inner side wall by a first spacing, the second side faces the second side The inner sidewall is spaced apart from the second inner sidewall by a second spacing. Thereby, in practice, the structural dimension of the fixing portion with respect to the through hole (for example, the peripheral contour in the direction and the through hole aperture, etc.) or the first spacing and the second spacing may be changed. Adjust the impedance of the electrical connector.

Another object of the present invention is to provide a terminal for use in an electrical connector. The terminal has a through hole in a portion fixed to the insulating body of the electrical connector, and the structural design helps to adjust the impedance of the electrical connector.

The terminal according to the present invention comprises a fixing portion, a contact portion and a connecting portion. The fixing portion has a first side surface and a second side surface opposite to the first side surface. The fixing portion includes an abutting portion and a through hole, and the abutting portion is perpendicular to the first direction. One of the second direction protrusions is located at the abutting portion and extends through the first side surface and the second side surface, wherein the fixing portion is fixed in the electrical connector via the abutting portion. The contact portion extends from the fixing portion. The connecting portion extends from the fixing portion. Thereby, in practice, the impedance of the electrical connector can be adjusted by changing the aperture of the through hole and the abutment profile.

In this embodiment, the upper row of terminals 16 and the lower row of terminals 18 are logically equivalent, and the upper row of fixing holes 122 and the lower row of fixing holes 124 have the same logic structure. Therefore, the above row of terminals 16 and the upper row of fixing holes 122 are taken as an example. For the description of the lower row of terminals 18 and the lower row of the fixing holes 124, unless otherwise specified, the related description of the upper row of terminals 16 and the upper row of the fixing holes 122 can be directly referred to, and will not be further described. Please also refer to Figures 7 and 8. The fixing portion 164 of the upper row of terminals 16 has a first side surface 164a and a second side surface 164b opposite to the first side surface 164a. The fixing portion 164 includes a body 1642 and a first abutting portion 1644. And a second abutting portion 1646, the first abutting portion 1644 and the second abutting portion 1646 are convex in a second direction D2 perpendicular to the first direction D1, and the body 1642 is perpendicular to the first direction D1 and the second One of the directions D2 extends in the third direction D3 and connects the first abutting portion 1644 and the second abutting portion 1646. The fixing portion 164 extends in the third direction D3 as a whole, and the contact portion 162 and the connecting portion 166 extend from opposite ends of the fixing portion 164 in the third direction D3. The upper row of fixing holes 122 has a first inner side wall 1222 and a second inner side wall 1224 opposite to the first inner side wall 1222. The upper row of fixing holes 122 is first with respect to the second direction D2. A third inner sidewall 1226 and a fourth inner sidewall 1228 opposite the third inner sidewall 1226 are defined between the inner sidewall 1222 and the second inner sidewall 1224. The fixing portion 164 abuts the upper row of fixing holes 122 with the first abutting portion 1644 and the second abutting portion 1646 to fix the upper row of terminals 16 to the insulative housing 12 (or the fixing portion 164 is fixed to the upper row of fixing holes 122). ). In this embodiment, the upper row of terminals 16 are inserted into the upper row of fixing holes 122 in the third direction D3, and the second abutting portion 1646 is located between the first abutting portion 1644 and the contact portion 162, so in principle, the first abutment The outer diameter L1 of the portion 1644 in the second direction D2 is greater than the outer diameter L2 of the second abutting portion 1646 in the second direction D2, so that the upper row of terminals 16 can be smoothly inserted into the upper row of fixing holes 122 and the first abutting portion Both the 1644 and the second abutting portion 1646 can maintain an effective holding effect with the upper row of fixing holes 122.

In the present embodiment, the first abutting portion 1644 and the second abutting portion 1646 are both convex toward the two sides of the main body 1642 in parallel with the second direction D2, so the first abutting portion 1644 and the second abutting portion 1646 will simultaneously abut the third inner side wall 1226 and the fourth inner side wall 1228; but in practice, the first abutting portion 1644 and the second abutting portion 1646 may be parallel to the second direction D2 on the side of the body 1642 The raised structure (e.g., the upwardly convex structure of the fixing portion 164 in Fig. 4 abuts against the third inner side wall 1226; the lower side of the fixing portion 164 is kept flat and abuts against the fourth inner side wall 1228). In addition, in the embodiment, the upper row of fixing holes 122 form opposite grooves 1227, 1229 (extending in the third direction D3) in the second direction D2, and the width thereof (ie, the width in the first direction D1) It is substantially equal to the thickness of the upper row of terminals 16 in the first direction D1 (for example, when the upper row of terminals 16 is made of a metal plate member, that is, the thickness of the plate), which helps the upper row of terminals 16 to be smoothly inserted and positioned in the upper row. The fixing hole 122 is in the middle. In practice, the fixing portion 164 can be received only in the grooves 1227, 1229 by the first abutting portion 1644 and the second abutting portion 1646.

However, in practice, the body 1642 can also cause structural interference with the upper row of fixing holes 122 to contribute to the aforementioned holding force. In addition, in FIG. 8, the cross section of the upper row of terminals 16 is not vertically symmetrical with respect to the upper row of fixing holes 122, because the first abutting portion 1644 is embedded in the fourth inner side wall 1228 (ie, the fourth inner side wall is pushed downward). This is caused by 1228), which can also be understood from Figure 7 (a side view).

In this embodiment, when the fixing portion 164 is fixed in the upper row of fixing holes 122, the first side surface 164a faces the first inner side wall 1222 and is spaced apart from the first inner side wall 1222 by a first distance W1, and the second side surface 164b faces the second side. The inner side wall 1224 is spaced apart from the second inner side wall 1224 by a second spacing W2 such that an air band can exist between the first side surface 164a and the first inner side wall 1222, and between the second side surface 164b and the second inner side wall 1224. The first side surface 164a and the second side surface 164b are substantially parallel to the first inner side wall 1222 and the second inner side wall 1224, respectively. The impedance of the electrical connector 1 can also be adjusted (or changed) by designing the first pitch W1 and the second pitch W2; in practice, the first pitch W1 and the second pitch W2 can be designed as, but not limited to, equal and It is larger than one third of the outer diameter W0 of the fixing portion 164 in the first direction D1 (that is, the thickness corresponding to the fixing portion 164).

In the embodiment, the fixing portion 164 has a first through hole 1648 and a second through hole 1650, both of which penetrate the first side surface 164a and the second side surface 164b along the first direction D1. When the fixing portion 164 is fixed in the upper row of fixing holes 122, the first through holes 1648 and the second through holes 1650 are located in the upper row of fixing holes 122. The impedance of the electrical connector 1 can also be adjusted (or changed) by designing the dimensions of the first through hole 1648 and the second through hole 1650. In the present embodiment, the first through hole 1648 and the second through hole 1650 are respectively located at the first abutting portion 1644 and the second abutting portion 1646, and the first through hole 1648 and the second through hole 1650 are in the second direction D2. The apertures 1648a and 1650a are both larger than the outer diameter 1642a of the body 1642 in the second direction D2, and the first through hole 1648 is larger than the second through hole 1650 (or the aperture 1648a is larger than the aperture 1650a), but the implementation is not For example, the first through hole 1648 and the second through hole 1650 may not be formed on the first abutting portion 1644 and the second abutting portion 1646. For example, the impedance of the required electrical connector 1 may be obtained through a simple attempt. Aperture value.

In the present embodiment, the upper row of terminals 16 further includes a stop portion 168 extending from the connecting portion 166 in the second direction D2 (or upward). When the fixing portion 164 is fixed in the upper row of fixing holes 122, the blocking portion 168 abuts against the rear side 12b of the insulative housing 12, and can be inserted into the positioning mechanism of the upper row of fixing holes 122 as the upper row of terminals 16. In contrast, in the process of inserting the lower row of terminals 18 into the lower row of fixing holes 124, the connecting portion 186 of the lower row of terminals 18 faces the side surface 186a of the insulative housing 12 against the rear side 12b of the insulative housing 12 as a positioning mechanism. In addition, in the embodiment, after the lower row of terminals 18 are inserted into the lower row of fixing holes 124, the rear cover 14 is combined to the rear side 12b to cover the connecting portions 186 of the lower row of fixing holes 124 and the lower row of terminal portions 18; The fixing portion 184 of the lower row of terminals 18 is completely invisible from the rear side 12b. The connecting portion 166 of the upper row of terminals 16 is exposed to the rear cover 14, and the fixing portion 164 is also shielded by the blocking portion 168 and the connecting portion 166 in principle. The fixing portion 164 can also be regarded as being invisible from the rear side 12b. In addition, the rear cover 14 can provide a positioning effect for the upper row of terminals 16. Therefore, if the connecting portion 166 faces the side surface 166a of the insulative housing 12 against the rear cover 14 as a positioning mechanism, the blocking portion 168 can also be omitted.

In addition, in the embodiment, as shown in FIG. 1 and FIG. 8 , the plurality of upper rows of terminals 16 are identical in structure and are arranged in a first direction D1 at a first pitch P1 (the plurality of upper rows of fixing holes 122 ). In the same manner, the plurality of lower rows of terminals 18 are identical in structure and arranged in a first pitch D2 in a first direction D1 (the plurality of lower rows of fixing holes 124 are also the same). The first pitch P1 is the same as the second pitch P2. However, the implementation is not limited thereto. For example, the upper row of terminals 16 and the lower row of terminals 18 are each arranged at a different pitch in the first direction D1. Further, although the above description has been made by taking the electrical connector 1 of the double-row terminal as an example, the above description can be applied to the electrical connector of the single-row terminal. Moreover, although the above description uses the female end and the board side electrical connector (ie, the electrical connector 1) as an example, in practice, the foregoing description can also be applied to the male end, the cable connector, or even an adapter. , no further details.

In addition, in the embodiment, the upper row of terminals 16 has a plate-like structure, and can be cut and formed by a metal plate member. The plate-like structure extends parallel to the second direction D2 and the third direction D3, so the plurality of The upper row of terminals 16 are parallel and non-coplanar on the insulative housing 12; however, in practice, the upper row of terminals 16 can be modified from a bent plate-like structure. The lower row of terminals 18 are also the same and will not be described again. Referring to FIG. 9 and FIG. 10, only the structure of a simplified variation of one of the electrical connectors 1 is shown. For simplicity of explanation, the structure of a single row of terminals will be described as an example. As shown in FIG. 9 and FIG. 10, the terminal 19 is structurally equivalent to the simplified structure of the upper row of terminals 16 (or the lower row of terminals 18). Therefore, other descriptions about the terminal 19 (and the insulative housing 13 combined therewith) include For the description of the change, refer to the previous description of the upper row of terminals 16 (or the lower row of terminals 18), and no further details are provided. The terminal 19 includes a contact portion 192, a fixing portion 194 and a connecting portion 196. The contact portion 192 and the connecting portion 196 extend from opposite ends of the fixing portion 194 in the third direction D3. The fixing portion 194 has a first side surface 194a and a second side surface 194b opposite to the first side surface 194a. The fixing portion 194 includes a body 1942, an abutting portion 1944 and a through hole 1946. 1944 is connected to the body 1942 and protrudes in the second direction D2.

The fixing portion 194 is fixed to the insulating body 13 via the abutting portion 1944. The fixing hole 132 is inside. The fixing hole 132 has a first inner side wall 1322 facing the first side surface 194a and a second inner side wall 1324 facing the second side surface 194b. The first side surface 194a is spaced apart from the first inner side wall 1322 by a first spacing W1', and the second The side surface 194b is spaced apart from the second inner side wall 1324 by a second spacing W2'. The sum of the first spacing W1' and the second spacing W2' is greater than one third of the outer diameter W0' of the fixing portion 194 in the first direction D1. With the terminal 19 as a whole, the terminal 19 has a bent plate-like structure (bent perpendicular to the second direction D2), and the adjacent two terminals 19 are arranged in the second direction D2 (or coplanar) and fixed. In the corresponding fixing hole 132. This structure facilitates the fabrication of the terminal 19 by continuous stamping (ie, the terminals 19 are each connected to a strip, as shown by the dashed line in FIG. 9), and facilitates simultaneous insertion of the plurality of terminals 19 into the fixing holes 132 of the insulative housing 13 ( This can reduce the assembly cost by inserting the direction as indicated by the arrow in FIG. In practice, the terminal 19 and the associated insulative housing 13 can be expanded to a double-row terminal based on the foregoing description of the electrical connector 1, and will not be further described.
