[0135] Figures 33 to 40 Another embodiment of the electrical connector 100 of the present invention is disclosed, wherein Figures 33 to 40 andFigures 1 to 32 The same reference numerals used herein denote the same or corresponding technical features, and the description thereof will not be repeated in this utility model. Hereinafter, only the main distinguishing technical features of the electrical connector 100 described in these two embodiments will be described.
[0136] Please refer to Figures 33 to 40 As shown, in this embodiment, the plurality of first terminal module mounting grooves 113 are arranged at intervals along the second direction A2-A2. The first conductive housing 11 includes a plurality of first partition walls 114 arranged at intervals along the second direction A2-A2. Each first partition wall 114 is provided with a first notch 1140 at the bottom. The first partition wall 114 includes first side walls 1140a exposed in the first notch 1140 and located on both sides of the first notch 1140.
[0137] Similarly, the plurality of second terminal module mounting grooves 123 are arranged at intervals along the second direction A2-A2. The second conductive housing 12 includes a plurality of second partition walls 124 arranged at intervals along the second direction A2-A2. Each second partition wall 124 is provided with a second notch 1240 at the bottom. The second partition wall 124 includes second side walls 1240a exposed in the second notch 1240 and located on both sides of the second notch 1240.
[0138] Correspondingly, the first partition wall 523 of the mounting block 5 is provided with a first rib 5230 at its top, and the second partition wall 533 of the mounting block 5 is provided with a second rib 5330 at its top. The first rib 5230 is provided with first side wall surfaces 5230a on both sides thereof. The second rib 5330 is provided with second side wall surfaces 5330a on both sides thereof.
[0139] When the mounting block 5 is assembled with the first conductive housing 11 and the second conductive housing 12, the first rib 5230 of the mounting block 5 is clamped in the first notch 1140 of the first conductive housing 11, and the second rib 5330 of the mounting block 5 is clamped in the second notch 1240 of the second conductive housing 12. At this time, the first side wall surface 5230a of the first rib 5230 can be in close contact with the first side wall 1140a of the first partition wall 114, and the second side wall surface 5330a of the second rib 5330 can be in close contact with the second side wall 1240a of the second partition wall 124. With such a setting, the gap between the first partition wall 114 and the first spacer wall 523 is reduced, and the gap between the second partition wall 124 and the second spacer wall 533 is also reduced, which is beneficial to improving crosstalk during signal transmission and improving the quality of signal transmission. Of course, those skilled in the art can understand that the first rib 5230 and the first notch 1140 can also be swapped, that is, the first rib 5230 is provided on the first partition wall 114, and the first notch 1140 is provided on the first spacer wall 523. Similarly, the second rib 5330 and the second notch 1240 can also be swapped, that is, the second rib 5330 is provided on the second partition wall 124, and the second notch 1240 is provided on the second spacer wall 533.
[0140] The mounting block 5 is a metal mounting block or a composite mounting block formed by electroplating a metal material on an insulating material. Preferably, the mounting block 5 is a metal mounting block made of a metal material to provide a better shielding effect.
[0141] In an embodiment of the present invention, both the first rib 5230 and the second rib 5330 are electroplated adhesives to further improve crosstalk during signal transmission and improve the quality of signal transmission.
[0142] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the art. Although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify the present invention or make equivalent replacements, and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
