Description

Technical Field

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector that can operate stably in a high-frequency environment. Background Technology

[0002] In recent years, the booming development of the electronics industry and consumers' preference for lighter, thinner, smaller, and more portable electronic products have driven small electronic products to become the mainstream in the market. For these reasons, electronic devices are becoming increasingly smaller, leading to the miniaturization of circuit boards and corresponding connectors. However, with the miniaturization of circuits, the distance between terminals inside electronic components such as connectors is shortened, resulting in more frequent coupling between the electric fields of the terminals. This contributes to the generation of more noise signals and exacerbates crosstalk problems when transmitting high-frequency signals, causing connectors to be unable to operate stably in high-frequency environments.

[0003] Therefore, it is necessary to provide an electrical connector with better resistance to high-frequency noise and crosstalk. Summary of the Invention

[0004] The purpose of this utility model is to provide an electrical connector, comprising: a first insulating base, the first insulating base being elongated; a first terminal group, the first terminal group being disposed within the first insulating base and including a plurality of signal terminals and a plurality of ground terminals, with a ground terminal provided on each side of every two signal terminals; a second insulating base, the second insulating base being elongated and engaging with the first insulating base; a second terminal group, the second terminal group being disposed within the second insulating base and including a plurality of signal terminals and a plurality of ground terminals, wherein the ground terminals in the second terminal group are symmetrically arranged with respect to the ground terminals in the first terminal group; and a conductive plastic component disposed between the first insulating base and the second insulating base. The conductive plastic component is electrically connected to the grounding terminal in the first terminal group and the second terminal group. The conductive plastic component has a main body, a plurality of connecting blocks extending to the left and right from the main body, and a reinforcing rib disposed at the junction of the main body and the connecting blocks.

A spacer is connected between the main body, the partition and the connecting block. A spacer groove is formed between the spacer, the partition and the connecting block. The top and bottom walls of the first insulating seat and the second insulating seat are respectively inserted into the spacer groove. The outer side of the spacer corresponds to the inner side of the top and bottom walls of the first insulating seat and the second insulating seat.

The main body is clamped between the first insulating base and the second insulating base and protrudes from the top and bottom surfaces of both the first insulating base and the second insulating base. The connecting blocks are disposed on the main body and extend outward to be electrically connected to the grounding terminal.

[0029] To illustrate in detail the technical content, structural features, objectives, and effects of the electrical connector of this utility model, the following embodiments are provided in conjunction with the accompanying drawings.

[0030] Please see Figure 1 and Figure 2 The present invention provides an electrical connector 200 comprising a housing 50, an accommodating space 55 disposed inside the housing 50, an insulating body 40 disposed in the accommodating space 55, and a terminal assembly 100 disposed inside the insulating body 40.

[0031] Please see again Figure 3 The terminal assembly 100 includes a terminal holder assembly 10, a terminal group 20 fixed in the terminal holder assembly 10, and a conductive plastic component 30 fixed in the terminal holder assembly 10 and electrically connected to the terminal group 20. The terminal holder assembly 10 includes a first insulating base 11, a second insulating base 12 assembled with the first insulating base 11, and a conductive plastic component 30 clamped between the first insulating base 11 and the second insulating base 12. The terminal group 20 includes a first terminal group 21 passing through the first insulating base 11 and a second terminal group 22 passing through the second insulating base 12.

[0032] Please see again Figures 3 to 4 The terminal fixing assembly 10 is rectangular, and the first insulating seat 11 and the second insulating seat 12 are generally elongated and symmetrically arranged. The adjacent surfaces of the first insulating seat 11 and the second insulating seat 12 are respectively provided with grooves 111 and 121, which penetrate the top and bottom surfaces of the first insulating seat 11 and the second insulating seat 12 respectively. A plurality of through holes 1111 and 1211 are provided on the bottom surface of the grooves 111 and 121 respectively. The conductive plastic component 30 is fixed in the through holes 1111 and 1211, and protrudes from the grooves 111 and 121, extending beyond the top and bottom surfaces of both the first insulating seat 11 and the second insulating seat 12.

[0033] Please see Figure 3 and Figure 5 Both the first terminal group 21 and the second terminal group 22 include a plurality of signal terminals 201 and a plurality of ground terminals 202. The signal terminals 201 and the ground terminals 202 are spaced apart from each other, and two signal terminals 201 form a differential terminal pair. The two ground terminals 202 are located on both sides of a differential terminal pair.

[0034] Continue reading Figure 3 and Figure 5Both the signal terminal 201 and the ground terminal 202 are elongated strips and each includes a fixing part 201a and 202a fixed and covered in the terminal fixing base assembly 10, a mating part 201b and 202b extending upward from the fixing part 201a and 202a, and a welding part 201c and 202c extending downward from the fixing part 201a and 202a, respectively. The welding parts 201c and 202c extend downward and then bend outward and extend to be welded to a circuit board.

[0035] Please see Figure 3 and Figures 6 to 8 The conductive plastic component 30 is held by the terminal fixing assembly 10 and electrically connected between the first terminal group 21 and the second terminal group 22. In this embodiment, the conductive plastic component 30 is made of conductive plastic and has a main body 31, a plurality of connecting blocks 32 extending to the left and right from the main body 31, and a reinforcing rib 33 disposed between the main body 31 and the connecting blocks 32. The main body 31 is flat and is held between the first insulating seat 11 and the second insulating seat 12, and protrudes from the top and bottom surfaces of the first insulating seat 11 and the second insulating seat 12 by the grooves 111 and 121. The connecting blocks 32 are continuously disposed on the main body 31 at fixed intervals and extend outward to be electrically connected to the grounding terminal 202. The reinforcing rib 33 is disposed at the junction of the main body 31 and the connecting block 32, and is clamped between the first insulating seat 11 and the second insulating seat 12. The reinforcing rib 33 is designed to be slender and extends from the main body 31 to the left and right, and the distance of extension is less than the distance of extension of the connecting block 32 to the left and right, so as to strengthen the structural strength of the conductive plastic part 30.

[0036] In this preferred embodiment, all terminals in the first terminal group 21 and the second terminal group 22 are arranged symmetrically from left to right. The distance the main body 31 extends forward and backward is approximately the length of the arrangement of terminals 201 and 202. The distance the main body 31 extends upward beyond the first insulating base 11 and the second insulating base 12 is the same as the distance the main body 31 extends downward beyond the first insulating base 11 and the second insulating base 12. Furthermore, the distance the main body 31 extends downward does not exceed the bends of the welding portions 201c and 202c, thereby separating the space between the first terminal group 21 and the second terminal group 22. This separates the electric field of the signal terminal 201 of the first terminal group 21 from the electric field of the signal terminal 201 of the second terminal group 22, reducing the coupling between the two electric fields and suppressing the generation of noise signals, thus improving crosstalk problems. The connecting block 32 is housed in the through holes 1111 and 1211, and extends to the left and right sides in the through holes 1111 and 1211, respectively, and is electrically connected to the grounding terminal 202 in the first terminal group 21 and the second terminal group 22. The distance between the center lines of two adjacent connecting blocks 32 is the same as the distance between the center lines of two adjacent grounding terminals 202, so that all the grounding terminals 202 are interconnected through the conductive plastic part 30 and have the same potential.

[0037] Please see Figure 8 and Figure 9 To prevent gaps from forming between the connecting block 32 and the grounding terminal 202 when the grounding terminal 202 is bent, three protrusions 321 are provided at the connection between the connecting block 32 and the grounding terminal 202. The protrusions 321 abut against the fixing part 202a, so that the connecting block 32 can reliably contact and connect with the grounding terminal 202.

[0038] Please see Figure 6 , Figures 10 to 12 In another embodiment, the conductive plastic component 30 is further provided with a plurality of spacers 34 extending to the left and right from the main body 31. The spacers 34 are continuously disposed on the main body 31 at the same fixed interval as the connecting block 32, and the spacers 34 are respectively located on the upper side and the lower side of the connecting block 32. The ends of the spacers 34 are spaced apart from the grounding terminal 202. The spacers 34 protrude from the top and bottom surfaces of both the first insulating base 11 and the second insulating base 12 to divide the space between the first terminal group 21 and the second terminal group 22 into a plurality of small compartments, thereby isolating the electric fields of all the differential terminal pairs, reducing the coupling between the electric fields of the differential terminal pairs, and suppressing the generation of noise signals.

[0039] The connecting block 32 is housed within the fixing base assembly 10, and the partition plate 34 is exposed on the top and bottom surfaces of the fixing base assembly 10. The connecting block 32 and the partition plate 34 are separated from each other, forming a gap groove 35 between them. The top and bottom walls of the fixing base assembly 10 are engaged in the gap groove 35. A gap portion 36 connects the connecting block 32 and the partition plate 34, and the gap portion 36 connects the main body 31, the connecting block 32, and the partition plate 34. The gap groove 35 is formed between the gap portion 36, the connecting block 32, and the partition plate 34. The outer surface of the gap portion 36 corresponds to the inner surface of the top and bottom walls of the fixing base assembly 10.

[0040] In summary, this invention electrically connects all the grounding terminals 202 in the first terminal group 21 and the second terminal group 22 through the conductive plastic component 30, thereby eliminating the potential difference between the grounding terminals 202 and pushing the resonant point of crosstalk to a higher frequency. Furthermore, the conductive plastic component 30 is provided with the main body 31 and the spacer 34, both of which protrude from the top and bottom surfaces of the first insulating base 11 and the second insulating base 12, respectively, to separate the electric fields of all the differential terminal pairs in the first terminal group 21 and the second terminal group 22, weakening the coupling phenomenon between the electric fields and thus reducing noise signals. Therefore, the electrical connector 200 of this invention can effectively suppress the resonant point of crosstalk, improve the crosstalk problem of high-frequency signals, and enhance the transmission capability of high-frequency signals.

[0041] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
