Description

Technical Field

[0001] The invention belongs to the field of electrical connectors, and in particular relates to a terminal module of an orthogonal connector and an orthogonal connector. Background Art

[0002] The terminal module of the connector generally includes an insulator, a signal terminal located in the insulator, a ground terminal, and shielding sheets located on both sides of the insulator. The signal terminal is arranged in the form of a differential pair, and one end of the signal terminal and the ground terminal protrude from the insulator to form a signal contact and a ground contact, respectively. The orthogonal connector assembly is used to connect two vertical circuit boards, so the terminal of an orthogonal connector in the orthogonal connector assembly needs to be bent vertically.

[0003] The Chinese invention patent application with the existing application publication number CN112636046A and the application publication date of April 9, 2021 discloses a chip, an orthogonal connector and a connector assembly of an orthogonal connector, wherein the chip (terminal module) includes an insulating frame (insulator), and a signal differential pair and a ground terminal are provided on the insulating frame. The signal differential pair includes two signal terminals, and the signal terminal includes a signal contact located at the mating end, and the ground terminal includes a ground contact located at the mating end; the signal contacts and the ground contacts both extend along a first direction and are arranged at intervals along a second direction perpendicular to the first direction. The signal contacts and the ground contacts are both bent vertically relative to the main body part of the corresponding terminal, and the two signal contacts in the same signal differential pair are arranged side by side along a third direction perpendicular to the first direction and the second direction.

[0004] In the above-mentioned terminal module, the signal terminal and the ground terminal are both made of the same metal strip through punching and bending, and the vertically bent structures on the signal terminal and the ground terminal need to occupy a larger size of the original metal strip in the second direction. If the vertical bends on the signal terminal and the ground terminal are aligned in the second direction, then in order to have enough material to process the signal contact and the ground contact, the entire terminal module needs to have a larger size in the second direction. Therefore, in order to keep the size of the terminal module in the second direction small, it is necessary to stagger the vertical bend structures on the two signal terminals of the same differential pair and the adjacent ground terminals in the second direction.

[0005] The two signal terminals in the same differential pair need to maintain a stable spacing to achieve better coupling and reduce crosstalk during high-speed data transmission, which requires that the vertical bending structures of the two signal terminals in the same differential pair be aligned or symmetrically arranged in the second direction. However, this will result in insufficient material reserved on the original metal sheet for making ground contacts while the size of the terminal module in the second direction remains unchanged, making it more difficult to perform vertical bending of the ground terminals. Summary of the invention

[0006] One of the purposes of the present invention is to provide a terminal module of an orthogonal connector to solve the technical problem in the prior art that if the vertical bending structures on the two signal terminals in the same differential pair are aligned in the second direction for the purpose of better coupling, there will not be enough space on the material strip to integrally process the grounding contact on the grounding terminal, thereby affecting normal shielding.

[0033] The present invention is further described in detail below in conjunction with embodiments.

[0034] In order to solve the problems in the prior art, the basic concept of the present invention is to separate the grounding contact and the grounding terminal so that there is no need to reserve space on the material strip for making the grounding contact. While ensuring that the size of the entire terminal module in the second direction remains unchanged, the vertical bending structure is aligned in the second direction, thereby improving the coupling effect and the signal transmission quality.

[0035] Specific embodiment 1 of the orthogonal connector provided by the present invention: An orthogonal connector, see attached Figure 1 , including a housing and a terminal module installed in the housing, the terminal module including a first terminal module and a second terminal module alternately arranged along a third direction.

[0036] See attached Fig. 9 , Attachment Fig.10 And attached Fig.11 The housing includes an insulating shell 1 and a common ground conductor 2. The common ground conductor 2 is installed in the insulating shell 1 to achieve common grounding of each terminal module. This is a prior art and will not be described in detail here.

[0037] See attached Figure 2 and attached Figure 3 The terminal modules all include an insulator 3, signal terminals 4 and ground terminals 5 located in the insulator 3, and shielding sheets located on both sides of the insulator 3. The signal terminals 4 are arranged in pairs, and two signal terminals 4 form a differential pair. The differential pairs and ground terminals 5 are alternately arranged in a plane perpendicular to the thickness direction of the insulator 3 in the insulator 3.

[0038] The thickness direction of the insulator 3 is taken as the third direction, the first direction and the second direction are two directions perpendicular to the third direction, and the first direction and the second direction are perpendicular to each other.

[0039] The terminal module has a mating end and a connecting end, wherein the connecting end is used to connect to the printed circuit board, and the mating end is used to mate with the terminal module in the adapter connector. The two ends of the signal terminal 4 and the ground terminal 5 are located at the mating end and the connecting end respectively.

[0040] See attached Figure 4 At the connection end, the differential pairs and the ground terminals 5 are arranged alternately in the first direction, the ends of the signal terminals 4 and the ground terminals 5 at the connection end are processed into fisheyes, and the fisheyes of the signal terminals 4 and the fisheyes of the ground terminals 5 are arranged alternately in the first direction. At the mating end, the differential pairs and the ground terminals 5 are arranged alternately in the second direction.

[0041] The signal terminal 4 includes a terminal body 41 and a signal contact 42. The signal contact 42 is connected to the terminal body 41 through a vertical bending structure 43, so that the signal contact 42 is in a vertical state after being bent with the terminal body 41. The two terminal bodies 41 in the same differential pair are located at one end of the mating end in the insulator 3 and are arranged at intervals along the second direction. The two signal contacts 42 in the same differential pair are arranged at intervals along the third direction. The thickness direction of the terminal body 41 is in the same direction as the third direction, and the thickness direction of the signal contact 42 is in the same direction as the second direction.

[0042] In order to ensure good coupling between the two signal terminals 4 in the same differential pair at the mating end and thus reduce crosstalk, the vertical bending structures 43 on the two signal terminals 4 in the same differential pair need to be aligned along the second direction and the two vertical bending structures 43 are centrally symmetrical. Specifically, the vertical bending structure 43 is composed of a first transition portion 431 and a second transition portion 432 from the terminal body 41 to the signal contact 42. The first transition portion 431 is located on the side of the corresponding terminal body 41 away from the other terminal body 41 in the same differential pair and is bent vertically in the third direction, so that a vertical angle is formed between the first transition portion 431 and the terminal body 41, and the bending directions of the two first transition portions 431 in the same differential pair are opposite; the second transition portion 432 is bent toward the position between the two signal terminals 4 of the same differential, so that an obtuse angle is formed between the second transition portion 432 and the first transition portion 431; finally, after the signal contact 42 is bent again, an obtuse angle is formed between the signal contact 42 and the second transition portion 432, and the two signal contacts 42 in the same differential pair are arranged along the third direction and extend along the first direction. The vertical bending structures 43 on the two signal terminals 4 in the same differential pair mentioned above are aligned along the second direction, which means that the first transition portions 431 in the vertical bending structures 43 on the two signal terminals 4 in the same differential pair are aligned accordingly, the second transition portions 432 are also aligned accordingly, and the end where the terminal body 41 is connected to the vertical bending structure 43 is aligned accordingly, and the end where the signal contact 42 is connected to the vertical bending structure 43 is aligned accordingly.

[0043] The first transition portion 431 is located on a side of the corresponding terminal body 41 away from the other terminal body 41 in the same differential pair, which can avoid the local spacing between the two signal terminals 4 in the same differential pair being too large and ensure better coupling; the two first transition portions 431 in the same differential pair are bent in opposite directions, which can ensure that the two vertical bending structures 43 in the same differential pair are symmetrically arranged, so that the two signal terminals 4 in the same differential pair are better coupled.

[0044] After the vertical bending structures 43 on the two signal terminals 4 in the same differential pair are aligned in the second direction, the bending structures will occupy the space in the second direction of the material strip. Without increasing the size of the terminal module in the second direction, the two adjacent differential pairs punched out on the material strip are almost connected at the vertical bending structure 43, so there is no excess material on the material strip to process the grounding contact 8 on the grounding terminal 5.

[0045] The two shielding sheets located on both sides of the insulator 3 are respectively a first shielding sheet 6 and a second shielding sheet 7, see the attached Figure 2 , Attachment Figure 3 And attached Figure 5 In this embodiment, the grounding contact 8 is integrally arranged at the end of the first shielding sheet 6 at the mating end, and the number of the grounding contacts 8 corresponds to the number of the grounding terminals 5 and the position in the second direction also corresponds. The grounding contact 8 includes a contact root 82 extending along the third direction and a contact body 81 extending along the first direction. The contact root 82 and the contact body 81 are L-shaped as a whole. The contact root 82 is connected to the first shielding sheet 6 by an angle structure formed by vertical bending, and the angle structure is a right angle formed by bending. The end of the grounding contact 8 connected to the first shielding sheet 6 is the contact root 82, which extends along the third direction to between the signal contacts 42 of two adjacent differential pairs and is aligned with one of the signal contacts 42 in the second direction. In addition to the above-mentioned method, the grounding contact 8 can also be independently processed and then integrally connected to the first shielding sheet 6 by welding.

[0046] Specifically, the terminal module in the orthogonal connector includes a first terminal module and a second terminal module, and the structures of the first terminal module and the second terminal module are similar. Figure 3 The contact root 82 of the grounding contact 8 in the first terminal module extends along the third direction to the position of the grounding terminal 5 and is conductively connected to the grounding terminal 5, see the attached Figure 7 , and the contact root 82 of the grounding contact 8 in the second terminal module extends along the third direction to the second shielding piece 7 of the terminal module and is conductively connected to the second shielding piece 7 .

[0047] The above-mentioned conductive connection method is as follows: Figure 6The second shielding sheet 7 of the first terminal module is provided with a notch 9, and the contact root 82 of the corresponding grounding contact 8 is interference-fitted in the notch 9; see the attached Figure 8 , and a notch 9 is formed on the ground terminal 5 of the second terminal module, and a contact root 82 of the corresponding ground contact 8 is interference-fitted into the notch 9 .

[0048] Using the notch 9 to fix the grounding contact 8 can not only realize the conductive connection between the grounding contact 8 and the grounding terminal 5 or the second shielding sheet 7, but also improve the stability of the grounding contact 8. In other embodiments, the grounding contact 8 in the first terminal module can be connected to the corresponding grounding terminal 5, and the grounding contact 8 in the second terminal module can be connected to the corresponding second shielding sheet 7 by laser welding or brazing. In other embodiments, the grounding contact 8 can be brought into contact and conduction with the corresponding grounding terminal 5 or the grounding contact 8 can be brought into contact and conduction with the corresponding second shielding sheet 7 only by abutment. In other embodiments, peanut buckles can be used to make two shielding sheets or the shielding sheet and the grounding terminal 5 conductively connected to the same ground without making the grounding contact 8 conductively connected to the grounding terminal 5 or the second shielding sheet 7.

[0049] In this embodiment, the first terminal module and the second terminal module are alternately arranged along the third direction and cooperate with each other as needed. In other embodiments, only the first terminal module or only the second terminal module may be used according to actual conditions. During assembly, the common ground conductor 2 is first installed in the insulating shell 1, and then each terminal module is installed in the shell composed of the common ground conductor 2 and the insulating shell 1, and the shielding sheet is inserted into the slot on the common ground conductor 2, so that each shielding sheet is conductively connected to the common ground conductor 2, and the grounding contact 8 is inserted into the through hole on the common ground conductor 2 and conductively connected to the inner wall of the through hole to achieve common grounding of each grounding contact 8.

[0050] Specific embodiment 2 of the orthogonal connector provided by the present invention: This embodiment is based on Embodiment 1, and differs from Embodiment 1 in that the grounding contact 8 in this embodiment is manufactured separately, and during assembly, the grounding contact 8 is directly interference fitted into the notch 9 on the second shielding plate 7 in the first terminal module and into the notch 9 on the grounding terminal 5 in the second terminal module.

[0051] Specific embodiment 3 of the orthogonal connector provided by the present invention: This embodiment is based on Embodiment 1, and differs from Embodiment 1 in that the grounding contact 8 in this embodiment is manufactured separately, and a slot for inserting the grounding contact 8 is provided on the common ground conductor 2 in this embodiment. During assembly, the common ground conductor 2 is installed in the insulating shell 1, and then the grounding contacts 8 are installed one by one on the common ground conductor 2. After each terminal module is installed, the grounding contact 8 is conductively connected to the shielding sheet and the grounding terminal 5 through the common ground conductor 2. Therefore, in this embodiment, the common ground conductor 2 is used as a transition piece to conductively connect the grounding terminal 5 with the grounding contact 8.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents.
