Description

[0002] In a conventional connector structure, when an interface connector is directly connected to a circuit board, a plurality of gold-plated pieces for correspondingly connecting to a plurality of terminals of the interface connector are provided on the side of the circuit board facing the interface connector.

[0003] However, such a structural arrangement requires that the plurality of terminals of the interface connector be arranged in a single row. As a result, both the width of the interface connector and the width of the circuit board become relatively large, which makes the overall width of the connector structure relatively large, and the space occupation inside the electronic product also becomes relatively large.

[0023] To further clarify the purpose, technical solutions, and advantages of the embodiments of this application, the technical solutions of the embodiments of this application will be described clearly and completely below with reference to the drawings of the embodiments of this application, although it is clear that the embodiments described are only a part of the embodiments of this application, not all of them. All other embodiments obtained by a person skilled in the art without creative effort based on the embodiments of this application are within the scope of protection of this application.

[0024] The following disclosure provides many different embodiments or examples for realizing different structures of this application. To simplify the disclosure of this application, the components and installations of specific examples are described below. Of course, these are illustrative only and do not limit this application. This application may repeat reference numerals and / or letters in different examples. Such repetitions are for simplification and clarity and do not in themselves indicate relationships between the various embodiments and / or installations discussed.

[0025] For the sake of clarity, spatial relation terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the diagram. These relation terms include, for example, "internal," "external," "inside," "outside," "down," "downward," "up," "above," "front," and "back." Such spatial relation terms imply that other orientations of the device in use or operation are included, in addition to the orientations shown in the diagram. For example, if the device in the diagram undergoes a reversal of position, a change in orientation, or a change in movement state, these orientation indications will also change accordingly. For example, an element described as "below another element or feature" or "below another element or feature" may subsequently be oriented as "above another element or feature" or "above another element or feature." Thus, the exemplary term "below..." can include orientations that are above and below. The device may be oriented differently (90-degree rotation or other directions), and the spatial relation descriptors used in the text will be interpreted accordingly.

[0026] One embodiment of this application provides an adapter connector and a connector assembly, the adapter connector configured to achieve an indirect connection between the interface connector and the circuit board 8 in such a way that the layout and dimensions of the connection points between the interface connector and the circuit board 8 are adjusted, and at the same time, a relatively large crosstalk prevention space 3 is formed between the two rows of terminals of the adapter connector, thereby reducing crosstalk that occurs when the terminals inside the adapter connector transmit signals, thus avoiding the impact of crosstalk on the integrity and reliability of information transmission, and solving the technical problem in the prior art that crosstalk tends to affect the integrity and reliability of information transmission when signals are transmitted by an adapter connector.

[0027] Referring to Figures 1 to 12, a first embodiment of the present invention provides an adapter connector including a first terminal unit and a second terminal unit, the first terminal unit including a plurality of parallel first terminals 1, the first terminals 1 including a first connection portion 11, a first bend portion 12 and a second connection portion 13 connected in order, the first connection portion 11 being used to connect to a signal terminal in an interface connector and the second connection portion 13 being used to connect to a circuit board 8, as shown in Figures 4, 9 and 10.

[0028] The second terminal unit includes a plurality of parallel second terminals 2, each of which includes a third connection portion 21, a second bend portion 22, and a fourth connection portion 23 connected in order. Of these, the third connection portion 21 is used to connect to a signal terminal in an interface connector, and the fourth connection portion 23 is used to connect to a circuit board 8, as shown in Figures 4, 9, and 10.

[0029] The first and second terminal units are installed sequentially along the first direction, and two rows of terminal connection points can be formed in the first direction, making it easy to change the terminal arrangement of the interface connector from a single row to a double row, as shown in Figure 7, which is advantageous in reducing the width dimension of the interface connector.

[0030] Both the first connection portion 11 and the third connection portion 21 extend along a first direction, and can each form a connection area of ​​a certain length in the first direction to facilitate matching with the terminal connection position of the interface connector. This allows for installation with different center height differences between the interface connector and the circuit board 8, improving the connection flexibility and convenience between the adapter connector and the interface connector and the circuit board 8.

[0031] One end of the first bent portion 12 is connected at an angle to the end of the first connecting portion 11 that is away from the third connecting portion 21, and one end of the second bent portion 22 is connected at an angle to the end of the third connecting portion 21 that is away from the first connecting portion 11, thereby maximizing the distance between the first bent portion 12 and the second bent portion 22, and forming a crosstalk prevention space 3 between the first bent portion 12 and the second bent portion 22, as shown in Figures 4 and 5.

[0032] Furthermore, the first terminal unit and the second terminal unit are installed facing each other in two rows inside the adapter connector, and a relatively large predetermined distance exists between the first bend 12 and the second bend 22, thereby forming a crosstalk prevention space 3. Even without installing a metal shielding member between the first terminal unit and the second terminal unit, the presence of the crosstalk prevention space 3 can reduce the crosstalk that occurs between any pair of first terminals 1 and second terminals 2 installed facing each other in the first direction, thereby avoiding the impact of crosstalk on the integrity and reliability of information transmission, and thereby reducing or avoiding the adverse effects of the installation of the adapter connector on the integrity and reliability of information transmission between the interface connector and the circuit board 8.

[0033] In the above embodiment, the connection angle between the first connecting portion 11 and the first bent portion 12 is preferably a right angle or an obtuse angle such that the first bent portion 12 is as far away from the second bent portion 22 as possible. Similarly, the connection angle between the third connecting portion 21 and the second bent portion 22 is preferably a right angle or an obtuse angle such that the second bent portion 22 is as far away from the first bent portion 12 as possible, thereby increasing the distance between the first bent portion 12 and the second bent portion 22.

[0034] In some preferred embodiments of this application, referring to Figures 4 and 5, the first bend 12 includes a first straight segment 121, and one end of the first straight segment 121 is perpendicularly connected to the end of the first connector 11 away from the third connector 21, so that the first straight segment 121 extends along a direction perpendicular to the first direction, and avoids increasing the dimensions of the adapter connector in the first direction if the first straight segment 121 is installed to protrude excessively from the first connector 11 (i.e., to protrude upward in Figure 5).

[0035] The second bend 22 includes a second straight segment 221, and one end of the second straight segment 221 is perpendicularly connected to the end of the third connector 21 that is away from the first connector 11, so that the second straight segment 221 extends in a direction perpendicular to the first direction, and avoids increasing the dimensions of the adapter connector in the first direction if the second straight segment 221 is installed to protrude excessively from the third connector 21 (i.e., to protrude downward in Figure 5).

[0036] Furthermore, since the first linear segment 121 and the second linear segment 221 are installed in parallel, and the parallel wiring installation method between the first linear segment 121 and the second linear segment 221 is symmetrical with respect to the external electromagnetic field, some interference signals can be canceled out, improving the stability of the adapter connector in a complex electromagnetic environment.

[0037] In some embodiments of this application, referring to Figures 4 and 5, the first straight segment 121 and the second straight segment 221 are installed parallel to each other, and the length of the first straight segment 121 is greater than the length of the second straight segment 221. The projection of the second bend 22 and the fourth connection 23 in the first direction overlaps with the projection of the first straight segment 121, making it easier to achieve misaligned installation of the fourth connection 23 and the second connection 13. Mutual interference between multiple fourth connection 23 and multiple second connection 13 can be avoided, thereby making it easier to achieve misaligned connection between the fourth connection 23, the second connection 13 and the circuit board 8. At the same time, the projections of the two rows of terminals on the circuit board 8 partially overlap, which is advantageous in reducing the layout area of ​​the circuit board 8.

[0038] In some embodiments of this application, referring to Figures 4, 5, 9, and 10, the second connection portion 13 and the fourth connection portion 23 are installed on the same plane, making it easy to connect to the same side of the circuit board 8, which is advantageous for realizing a compact connection between the adapter connector and the circuit board 8.

[0039] In the above embodiment, the shape of the first bent portion 12 may be set according to the relative position between the first connecting portion 11 and the second connecting portion 13, and the shape of the second bent portion 22 may be set according to the relative position between the third connecting portion 21 and the fourth connecting portion 23. In either case, the objective of this application can be achieved as long as a crosstalk prevention space 3 exists between the first bent portion 12 and the second bent portion 22.

[0040] In some preferred embodiments of this application, referring to Figures 4 and 5, the first bend 12 is a horizontally oriented L-shaped structure, and the second bend 22 is a horizontally oriented S-shaped structure, with the opening direction of the L-shaped structure facing the second bend 22, thereby maximizing the relative distance between the first bend 12 and the second bend 22, and thereby ensuring the crosstalk prevention effect of the crosstalk prevention space 3.

[0041] Specifically, the first direction is vertical, and the first bent portion 12 of the first terminal 1 includes a first straight segment 121 and a first vertical segment 122 connected in an L-shape, and the first vertical segment 122 is connected perpendicularly to the second connecting portion 13, so that the first terminal 1 as a whole has a bent shape. The second bend 22 of the second terminal 2 includes an S-shaped connected second straight segment 221, an inclined segment 222, a third straight segment 223, and a second vertical segment 224, and the second vertical segment 224 is connected perpendicularly to the fourth connection 23. The second connection 13 and the fourth connection 23 are installed on the same plane and are both connected to the circuit board 8. The orientation of the second bend 22 can be changed by installing the inclined segment 222, the third straight segment 223, and the second vertical segment 224, thereby facilitating the connection between the second bend 22 and the fourth connection 23 and adapting to the mounting height of the circuit board 8.

[0042] Furthermore, both the first terminal 1 and the second terminal 2 employ rounded corner connections in the bending region, thereby achieving stress distribution, avoiding abrupt changes in impedance, and ensuring high-speed signal transmission quality (e.g., 10 Gbps or more).

[0043] Referring to Figures 1 to 12, a second embodiment of the present invention provides a connector assembly that includes the adapter connector described in the above embodiment, and further includes an interface connector, wherein the end of the interface connector is provided with a third terminal unit and a fourth terminal unit that are sequentially installed along a first direction.

[0044] The third terminal unit includes a plurality of parallel third terminals 5, each third terminal 5 including a first elastic portion 51 positioned toward the first terminal 1, the first elastic portion 51 elastically contacting the first connection portion 11 to enable electrical conductivity between the third terminal 5 and the first terminal 1; the fourth terminal unit includes a plurality of parallel fourth terminals 6, each fourth terminal 6 including a second elastic portion 61 positioned toward the second terminal 2, the second elastic portion 61 elastically contacting the third connection portion 21 to enable electrical conductivity between the fourth terminal 6 and the second terminal 2, as shown in Figures 6, 7, 8, and 10.

[0045] Furthermore, since both the first connection portion 11 and the second connection portion 13 extend along the first direction, a connection area of ​​a certain length is formed in the first direction and can be used to contact the first elastic portion 51 or the second elastic portion 61. The adapter connector is movable relative to the end of the interface connector in the first direction, and specifically, when the first direction is vertical, the adapter connector can support different connection height requirements by sliding up and down relative to the end of the interface connector, significantly improving the usability of the product.

[0046] In some embodiments of this application, the adapter connector includes a first insulating body 4, and the first and second terminal units are fixedly installed by being fitted inside the first insulating body 4, as shown in Figures 1, 2, and 3. The interface connector includes a second insulating body 7, and the third and fourth terminal units are fixedly installed by being fitted inside the second insulating body 7, as shown in Figures 6, 7, and 10.

[0047] A first engaging portion 41 is provided on the side of the first insulating body 4 facing the second insulating body 7, and a second engaging portion 72 is provided on the side of the second insulating body 7 facing the first insulating body 4. The first engaging portion 41 and the second engaging portion 72 are installed in a matching manner, enabling assembly positioning between the first insulating body 4 and the second insulating body 7. This allows multiple third terminals 5 and multiple first terminals 1 to be brought into one-to-one contact, and multiple fourth terminals 6 and multiple second terminals 2 to be brought into one-to-one contact, ensuring connection accuracy between the interface connector and the adapter connector, as shown in Figures 1, 7, 9, and 11.

[0048] In some preferred embodiments of this application, referring to Figures 1, 7, 9, and 11, the first engaging portion 41 or the second engaging portion 72 is a sliding groove extending along a first direction, thereby facilitating the adjustment of the assembly position of the adapter connector and interface connector according to connection height requirements, by providing a sliding guide in the first direction via the sliding groove, thereby ensuring connection accuracy between the adapter connector and the interface connector.

[0049] In some embodiments of this application, referring to Figures 7, 8, and 10, a plurality of limiting grooves 71 are provided at the end of the second insulating body 7, and each of the limiting grooves 71 is installed in a one-to-one correspondence with a plurality of first elastic parts 51 and a plurality of second elastic parts 61, so as to be able to achieve spacing and limiting between any two elastic parts (including the first elastic part 51 and the second elastic part 61), and both the first elastic part 51 and the second elastic part 61 are installed protruding from the limiting grooves 71 and are used to abut against the first connection part 11 and the second connection part 13, respectively.

[0050] Furthermore, the ends of both the first elastic portion 51 and the second elastic portion 61 abut against the inside of the limiting groove 71, and as shown in Figure 10, only a portion of the elastic portion can be installed protruding from the limiting groove 71, and the elastic portion does not completely escape to the outside of the limiting groove 71 during deformation, thereby ensuring the reliability of the elastic contact function of the elastic portion.

[0051] In some embodiments of this application, referring to Figure 10, the third terminal 5 includes a fifth connector 52 connected to the first elastic portion 51, and the fifth connector 52 is fitted onto the upper side of the insulating tongue of the second insulating body 7, and the fourth terminal 6 includes a sixth connector 62 connected to the second elastic portion 61, and the sixth connector 62 is fitted onto the lower side of the insulating tongue of the second insulating body 7, thereby enabling the third terminal 5 and the fourth terminal 6 to be fixedly installed, and providing a reaction force to the first elastic portion 51 and the second elastic portion 61 when they come into contact with each other.

[0052] In some embodiments of this application, referring to Figures 6, 10, and 12, the connector assembly further includes a circuit board 8, and the second connector 13 and the fourth connector 23 are both connected to the circuit board 8, thereby enabling information transmission between the interface connector and the circuit board 8 by a plurality of first terminals 1 and a plurality of second terminals 2.

[0053] In some embodiments of this application, referring to Figure 12, the circuit board 8 includes two rows of conductive regions arranged sequentially along a second direction, each of which includes multiple conductive points, the multiple conductive points in one row of conductive regions being connected to a plurality of second connection parts 13, and the multiple conductive points in the other row of conductive regions being connected to a plurality of fourth connection parts 23, thereby achieving corresponding conductivity with the terminal units at both ends of the adapter connector (i.e., the first terminal unit and the second terminal unit), which is advantageous for achieving a compact layout design of the circuit board 8 and reducing the width dimension of the circuit board 8.

[0054] Specifically, the second direction is horizontal, and the two conductive regions are represented as the first conductive region 81 and the second conductive region 82, respectively. The first conductive region 81 is located on the side of the circuit board 8 closer to the adapter connector and is used to establish conductivity with the fourth connection portion 23 of the second terminal 2, while the second conductive region 82 is located on the side of the circuit board 8 further from the adapter connector and is used to establish conductivity with the second connection portion 13 of the first terminal 1, matching the arrangement of the first terminal 1 and the second terminal 2, as shown in Figure 10.

[0055] In some embodiments of this application, referring to Figures 1, 6, and 12, a first positioning portion 42 is provided at the bottom of the first insulating body 4, and a second positioning portion 83 is provided on the circuit board 8, which is installed to match the first positioning portion 42. By fitting the first positioning portion 42 and the second positioning portion 83, assembly positioning can be achieved between the second connection portion 13 and the second conductive region 82, and between the fourth connection portion 23 and the first conductive region 81.

[0056] Specifically, the first positioning section 42 consists of positioning columns installed on both sides of the bottom of the first insulating body 4, and the second positioning section 83 consists of positioning holes installed on both sides of the circuit board 8. By inserting the positioning columns into the corresponding positioning holes, assembly positioning between the adapter connector and the circuit board 8 can be achieved.

[0057] In some embodiments of this application, referring to Figures 6 and 7, the connector assembly is further manufactured from a metallic material and includes a housing assembly 9 for providing physical protection and electromagnetic shielding functions for the connector assembly.

[0058] Specifically, the housing assembly 9 includes a first housing 91, a second housing 92, and a third housing 93. The first housing 91 covers the outside of the first insulating body 4, and a housing conduction portion 84 is provided on the circuit board 8 for connecting to the first housing 91 to achieve a grounded state. The second housing 92 covers the outside of the second insulating body 7, and the third housing 93 covers the outside of the second housing 92 and can be used to achieve electromagnetic shielding and mounting.

[0059] Referring to Figures 1 to 12, in some embodiments of this application, the assembly process for the connector assembly is as follows:

[0060] Step 1: The adapter connector and the circuit board 8 are assembled and positioned using the first positioning part 42 and the second positioning part 83, and the multiple second connection parts 13 are connected to correspond to multiple conductive points in the second conductive region 82 on the circuit board 8, and the multiple fourth connection parts 23 are connected to correspond to multiple conductive points in the first conductive region 81 on the circuit board 8.

[0061] Step 2: The first engaging portion 41 and the second engaging portion 72 enable assembly and positioning between the first insulating body 4 and the second insulating body 7. By sliding the first engaging portion 41 and the second engaging portion 72 relative to each other along the first direction, the assembly position between the interface connector and the adapter connector is adjusted, the first elastic portion 51 is brought into contact with the first connecting portion 11, and the second elastic portion 61 is brought into contact with the third connecting portion 21.
