Description

Technical Field

[0001] This application relates to the field of electronic connection technology, and in particular to an adapter connector and connector assembly. Background Technology

[0002] In a conventional connector structure, when the interface connector is directly connected to the circuit board, multiple gold fingers are provided on the side of the circuit board facing the interface connector for corresponding connection with multiple terminals in the interface connector.

[0003] However, this structural design requires multiple terminals in the interface connector to be arranged in a row, which makes the width of the interface connector and the width of the circuit board larger, resulting in a larger overall width of the connector structure and a larger space occupancy rate inside the electronic product.

[0004] If the adapter is used to connect to the interface connector and the circuit board signal respectively, the adapter has a relatively simple structure and usually does not have a shield. This makes it easy for crosstalk to occur between the internal terminals of the adapter, which will adversely affect the integrity and reliability of information transmission during the adapter process. Utility Model Content

[0005] This application provides an adapter connector and connector assembly to solve the technical problem in the prior art where crosstalk can easily affect the integrity and reliability of information transmission when transmitting signals through an adapter connector.

[0008] The second terminal unit includes a plurality of second terminals arranged side by side, and each second terminal includes a third connecting part, a second bending part and a fourth connecting part connected in sequence.

[0009] The first terminal unit and the second terminal unit are arranged sequentially along the first direction, and the first connecting part and the third connecting part both extend along the first direction. One end of the first bent part is connected at an angle to the end of the first connecting part away from the third connecting part; one end of the second bent part is connected at an angle to the end of the third connecting part away from the first connecting part, and an anti-crosstalk space is formed between the first bent part and the second bent part.

[0010] Optionally, the first bend includes a first straight section, one end of which is perpendicularly connected to the end of the first connecting portion away from the third connecting portion;

[0011] The second bend includes a second straight section, one end of which is perpendicularly connected to the end of the third connecting portion that is away from the first connecting portion.

[0012] Optionally, the first straight segment and the second straight segment are arranged in parallel, and the length of the first straight segment is greater than the length of the second straight segment; the projection of the second bent portion and the fourth connecting portion in the first direction overlaps with the projection of the first straight segment.

[0013] Optionally, the second connecting part and the fourth connecting part are arranged in the same plane.

[0014] Optionally, the first bend is a horizontally placed L-shaped structure, and the second bend is a horizontally placed S-shaped structure, with the opening of the L-shaped structure facing the second bend.

[0015] In a second aspect, this application provides a connector assembly, including the adapter connector provided in the first aspect of this application, and also including an interface connector, wherein the tail end of the interface connector is provided with a third terminal unit and a fourth terminal unit arranged sequentially along a first direction;

[0016] The third terminal unit includes a plurality of third terminals arranged side by side. Each third terminal includes a first elastic portion disposed toward the first terminal. The first elastic portion elastically abuts against the first connecting portion.

[0017] The fourth terminal unit includes a plurality of fourth terminals arranged side by side. Each fourth terminal includes a second elastic portion disposed toward the second terminal, and the second elastic portion elastically abuts against the third connecting portion.

[0018] Optionally, the adapter connector includes a first insulating body, and a first terminal unit and a second terminal unit are both embedded inside the first insulating body; the interface connector includes a second insulating body, and a third terminal unit and a fourth terminal unit are both embedded inside the second insulating body.

[0019] The first insulating body has a first snap-fit ​​portion on the side facing the second insulating body, and the second insulating body has a second snap-fit ​​portion on the side facing the first insulating body. The first snap-fit ​​portion and the second snap-fit ​​portion are matched and configured.

[0020] Optionally, the first or second snap-fit ​​portion is a groove extending along a first direction.

[0021] Optionally, the tail end of the second insulating body is provided with multiple limiting grooves, and the multiple limiting grooves are respectively provided in correspondence with multiple first elastic parts and multiple second elastic parts, and the first elastic parts and the second elastic parts both protrude from the limiting grooves.

[0022] Optionally, the connector assembly also includes a circuit board, with both the second and fourth connecting portions connected to the circuit board.

[0023] Optionally, the circuit board includes two rows of conductive areas arranged sequentially along the second direction. Each row of conductive areas includes multiple conductive points. The multiple conductive points in one row of conductive areas are connected to multiple second connecting parts, and the multiple conductive points in the other row of conductive areas are connected to multiple fourth connecting parts.

[0024] The technical solutions provided in this application have the following advantages compared with the prior art:

[0025] The adapter connector provided in this application embodiment can be used to realize indirect connection between interface connector and circuit board. The first terminal unit (including multiple first terminals) and the second terminal unit (including multiple second terminals) of the adapter connector are arranged sequentially along a first direction, which can form two rows of terminal connection points in the first direction. This allows the terminal arrangement of the interface connector to be changed from one row to two rows, which is beneficial to shortening the width of the interface connector. The first connecting portion of the first terminal and the third connecting portion of the second terminal both extend along the first direction, and can respectively form a connection area of ​​a certain length in the first direction to match the terminal connection position of the interface connector. This adapts to different center height differences between the interface connector and the circuit board, improving the flexibility and convenience of connection between the adapter connector, the interface connector, and the circuit board.

[0026] One end of the first bend of the first terminal is angularly connected to the end of the first connecting portion away from the third connecting portion; one end of the second bend of the second terminal is angularly connected to the end of the third connecting portion away from the first connecting portion. This maximizes the distance between the first bend and the second bend and forms an anti-crosstalk space between the first bend and the second bend. Even if no metal shield is provided between the first terminal unit and the second terminal unit, the existence of the anti-crosstalk space can reduce the crosstalk generated between any pair of first and second terminals that are opposite each other in the first direction. This reduces the adverse impact of the adapter connector on the integrity and reliability of information transmission between the interface connector and the circuit board.

[0027] The connector assembly provided in this application includes the aforementioned adapter connector. By using anti-crosstalk space, the adverse effects of the adapter connector's placement on the integrity and reliability of information transmission between the interface connector and the circuit board can be reduced or avoided. Therefore, it naturally possesses the technical effects of the aforementioned adapter connector. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0055] For ease of description, spatial relative 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 figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0056] To address the technical problem in the prior art where crosstalk can easily affect the integrity and reliability of information transmission when signal transmission is performed via adapter connectors, this application provides an adapter connector and connector assembly. The adapter connector can be used to achieve indirect connection between the interface connector and the circuit board 8, so as to facilitate the adjustment of the connection point layout and size of the interface connector and the circuit board 8. At the same time, since a large anti-crosstalk space 3 is formed between the two rows of terminals of the adapter connector, the crosstalk generated by the terminals inside the adapter connector during signal transmission can be reduced, thus avoiding the impact of crosstalk on the integrity and reliability of information transmission.

[0057] Please see Figures 1 to 12 The first aspect of this application provides an adapter connector, including a first terminal unit and a second terminal unit. The first terminal unit includes a plurality of first terminals 1 arranged side by side. Each first terminal 1 includes a first connecting portion 11, a first bending portion 12, and a second connecting portion 13 connected in sequence. The first connecting portion 11 is used to connect to a signal terminal in an interface connector, and the second connecting portion 13 is used to connect to a circuit board 8. Figure 4 , Figure 9 and Figure 10 As shown.

[0058] The second terminal unit includes multiple second terminals 2 arranged side by side. Each second terminal 2 includes a third connecting portion 21, a second bending portion 22, and a fourth connecting portion 23 connected in sequence. The third connecting portion 21 is used to connect to the signal terminals in the interface connector, and the fourth connecting portion 23 is used to connect to the circuit board 8. Figure 4 , Figure 9 and Figure 10 As shown.

[0059] The first terminal unit and the second terminal unit are arranged sequentially along the first direction, forming two rows of terminal connection points in the first direction. This allows the terminal arrangement of the interface connector to be changed from a single row to two rows. Figure 7 As shown, this helps to shorten the width of the interface connector.

[0060] Both the first connecting part 11 and the third connecting part 21 extend along the first direction and can form a connecting area of ​​a certain length in the first direction to match the terminal connection position of the interface connector, thereby adapting to different center height differences between the interface connector and the circuit board 8, and improving the flexibility and convenience of connection between the adapter connector, the interface connector and the circuit board 8.

[0061] One end of the first bend 12 is angled to the end of the first connecting portion 11 away from the third connecting portion 21; one end of the second bend 22 is angled to the end of the third connecting portion 21 away from the first connecting portion 11, which maximizes the distance between the first bend 12 and the second bend 22, and forms an anti-crosstalk space 3 between the first bend 12 and the second bend 22. Figure 4 and Figure 5 As shown.

[0062] It should be noted that the first terminal unit and the second terminal unit are arranged in two rows opposite each other inside the adapter connector. There is a large preset distance between the first bending part 12 and the second bending part 22, thereby forming an anti-crosstalk space 3. Even if there is no metal shield between the first terminal unit and the second terminal unit, the existence of the anti-crosstalk space 3 can reduce the crosstalk generated between any pair of first terminals 1 and second terminals 2 arranged opposite each other in the first direction. This can prevent crosstalk from affecting the integrity and reliability of information transmission, thereby reducing or avoiding the adverse effects of the adapter connector arrangement on the integrity and reliability of information transmission between the interface connector and the circuit board 8.

[0063] In the above embodiments, the connection angle between the first connecting portion 11 and the first bending portion 12 is preferably a right angle or an obtuse angle, so that the first bending portion 12 is as far away from the second bending portion 22 as possible; similarly, the connection angle between the third connecting portion 21 and the second bending portion 22 is preferably a right angle or an obtuse angle, so that the second bending portion 22 is as far away from the first bending portion 12 as possible, thereby increasing the distance between the first bending portion 12 and the second bending portion 22.

[0064] Please refer to some preferred embodiments of this application. Figure 4 and Figure 5The first bending portion 12 includes a first straight section 121, one end of which is perpendicularly connected to the end of the first connecting portion 11 away from the third connecting portion 21, so that the first straight section 121 extends in a direction perpendicular to the first direction, thus preventing the first straight section 121 from protruding excessively from the first connecting portion 11 (i.e., towards). Figure 5 When the upper side protrudes, the size of the adapter connector in the first direction is increased.

[0065] The second bend 22 includes a second straight section 221, one end of which is perpendicularly connected to the end of the third connecting portion 21 away from the first connecting portion 11. This allows the second straight section 221 to extend in a direction perpendicular to the first direction, preventing it from excessively protruding from the third connecting portion 21 (i.e., towards...). Figure 5 When the lower side protrudes, the size of the adapter connector in the first direction is increased.

[0066] It should be noted that the first straight section 121 and the second straight section 221 are arranged in parallel. Since the parallel routing arrangement of the first straight section 121 and the second straight section 221 has symmetry with the external electromagnetic field, it can cancel out some interference signals and improve the stability of the adapter connector in complex electromagnetic environments.

[0067] In some embodiments of this application, please refer to Figure 4 and Figure 5 The first straight section 121 and the second straight section 221 are arranged in parallel, and the length of the first straight section 121 is greater than the length of the second straight section 221. The projections of the second bent portion 22 and the fourth connecting portion 23 in the first direction overlap with the projection of the first straight section 121, which facilitates the staggered arrangement of the fourth connecting portion 23 and the second connecting portion 13, avoids interference between multiple fourth connecting portions 23 and multiple second connecting portions 13, and facilitates the staggered connection between the fourth connecting portion 23, the second connecting portion 13 and the circuit board 8. At the same time, it allows the projections of the two rows of terminals on the circuit board 8 to partially overlap, which helps to reduce the layout area of ​​the circuit board 8.

[0068] In some embodiments of this application, please refer to Figure 4 , Figure 5 , Figure 9 and Figure 10 The second connecting part 13 and the fourth connecting part 23 are arranged on the same plane, which facilitates connection with the board surface on the same side of the circuit board 8 and helps to achieve a compact connection between the adapter connector and the circuit board 8.

[0069] In the above embodiments, the shape of the first bending portion 12 can 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 bending portion 22 can be set according to the relative position between the third connecting portion 21 and the fourth connecting portion 23. As long as there is an anti-crosstalk space 3 between the first bending portion 12 and the second bending portion 22, the purpose of this application can be achieved.

[0070] Please refer to some preferred embodiments of this application. Figure 4 and Figure 5 The first bending part 12 is a horizontally placed L-shaped structure, and the second bending part 22 is a horizontally placed S-shaped structure. The opening direction of the L-shaped structure is set towards the second bending part 22 to maximize the relative distance between the first bending part 12 and the second bending part 22, thereby ensuring the anti-crosstalk effect of the anti-crosstalk space 3.

[0071] Specifically, the first direction is vertical. The first bending portion 12 of the first terminal 1 includes a first straight section 121 and a first vertical section 122 connected in an L-shape. The first vertical section 122 is perpendicularly connected to the second connecting portion 13, which makes the first terminal 1 as a whole form a Z-shape. The second bending portion 22 of the second terminal 2 includes a second straight section 221, an inclined section 222, a third straight section 223, and a second vertical section 224 connected in an S-shape. The second vertical section 224 is perpendicularly connected to the fourth connecting portion 23. The second connecting portion 13 and the fourth connecting portion 23 are coplanar and both are connected to the circuit board 8. By setting the inclined section 222, the third straight section 223, and the second vertical section 224, the direction of the second bending portion 22 can be changed, thereby facilitating the connection between the second bending portion 22 and the fourth connecting portion 23 while adapting to the installation height of the circuit board 8.

[0072] It should be noted that both the first terminal 1 and the second terminal 2 are connected with rounded corners in the bending area, which can achieve stress dispersion, avoid impedance abrupt changes, and ensure the transmission quality of high-speed signals (such as 10Gbps and above).

[0073] Please see Figures 1 to 12 The second aspect of this application provides a connector assembly, including the adapter connector described in the above embodiments, and further including an interface connector, wherein the tail end of the interface connector is provided with a third terminal unit and a fourth terminal unit arranged sequentially along a first direction;

[0074] The third terminal unit includes multiple third terminals 5 arranged side by side. Each third terminal 5 includes a first elastic portion 51 facing the first terminal 1. The first elastic portion 51 elastically abuts against the first connecting portion 11 to achieve conductivity between the third terminal 5 and the first terminal 1. The fourth terminal unit includes multiple fourth terminals 6 arranged side by side. Each fourth terminal 6 includes a second elastic portion 61 facing the second terminal 2. The second elastic portion 61 elastically abuts against the third connecting portion 21 to achieve conductivity between the fourth terminal 6 and the second terminal 2. Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown.

[0075] It should be noted that since both the first connecting part 11 and the second connecting part 13 extend along the first direction, a connecting area of ​​a certain length is formed in the first direction, which can be used to abut against the first elastic part 51 or the second elastic part 61. The adapter connector can move relative to the tail end of the interface connector in the first direction. Specifically, when the first direction is vertical, by sliding the adapter connector up and down relative to the tail end of the interface connector, different connection height requirements can be supported, greatly improving the performance of the product.

[0076] In some embodiments of this application, the adapter connector includes a first insulating body 4, and both the first terminal unit and the second terminal unit are embedded inside the first insulating body 4 to achieve a fixed arrangement of the first terminal unit and the second terminal unit, such as... Figure 1 , Figure 2 and Figure 3 As shown; the interface connector includes a second insulating body 7, and a third terminal unit and a fourth terminal unit are both embedded inside the second insulating body 7 to achieve a fixed arrangement of the third terminal unit and the fourth terminal unit, as shown. Figure 6 , Figure 7 and Figure 10 As shown.

[0077] The first insulating body 4 has a first snap-fit ​​portion 41 on the side facing the second insulating body 7, and the second insulating body 7 has a second snap-fit ​​portion 72 on the side facing the first insulating body 4. The first snap-fit ​​portion 41 and the second snap-fit ​​portion 72 are matched to achieve assembly positioning between the first insulating body 4 and the second insulating body 7, thereby ensuring that multiple third terminals 5 abut against multiple first terminals 1 in a one-to-one correspondence, and that multiple fourth terminals 6 abut against multiple second terminals 2 in a one-to-one correspondence, guaranteeing the accurate mating between the interface connector and the adapter connector. Figure 1 , Figure 7 , Figure 9 and Figure 11 As shown.

[0078] Please refer to some preferred embodiments of this application. Figure 1, Figure 7 , Figure 9 and Figure 11 The first snap-fit ​​portion 41 or the second snap-fit ​​portion 72 is a sliding groove that extends along the first direction, so that when the adapter connector and the interface connector are adjusted in assembly position according to the connection height requirements, the sliding groove can guide them in the first direction, ensuring the mating accuracy between the adapter connector and the interface connector.

[0079] In some embodiments of this application, please refer to Figure 7 , Figure 8 and Figure 10 The tail end of the second insulating body 7 is provided with a plurality of limiting grooves 71. The plurality of limiting grooves 71 are respectively provided in correspondence with a plurality of first elastic parts 51 and a plurality of second elastic parts 61, which can realize the spacing and limiting between any two elastic parts (including the first elastic part 51 and the second elastic part 61). The first elastic part 51 and the second elastic part 61 are both protruding from the limiting grooves 71 and are respectively used to abut against the first connecting part 11 and the second connecting part 13.

[0080] It should be noted that the ends of both the first elastic part 51 and the second elastic part 61 abut against the inner side of the limiting groove 71, such as... Figure 10 As shown, the elastic part can be partially protruded from the limiting groove 71, and the elastic part will not completely come out of the limiting groove 71 during the deformation process, which can ensure the reliability of the elastic abutment function of the elastic part.

[0081] In some embodiments of this application, please refer to Figure 10 The third terminal 5 includes a fifth connecting portion 52 connected to the first elastic portion 51, and the fifth connecting portion 52 is embedded on the upper side of the insulating tongue of the second insulating body 7; the fourth terminal 6 includes a sixth connecting portion 62 connected to the second elastic portion 61, and the sixth connecting portion 62 is embedded on the lower side of the insulating tongue of the second insulating body 7, which can realize the fixed setting of the third terminal 5 and the fourth terminal 6. When the first elastic portion 51 and the second elastic portion 61 are abutted, they can provide reaction force to the first elastic portion 51 and the second elastic portion 61 respectively.

[0082] In some embodiments of this application, please refer to Figure 6 , Figure 10 and Figure 12 The connector assembly also includes a circuit board 8, and the second connecting part 13 and the fourth connecting part 23 are both connected to the circuit board 8, thereby realizing information transmission between the interface connector and the circuit board 8 through multiple first terminals 1 and multiple second terminals 2.

[0083] In some embodiments of this application, please refer to Figure 12The circuit board 8 includes two rows of conductive areas arranged sequentially along the second direction. Each row of conductive areas includes multiple conductive points. Multiple conductive points in one row of conductive areas are connected to multiple second connecting parts 13, and multiple conductive points in the other row of conductive areas are connected to multiple fourth connecting parts 23. Corresponding conductive is achieved between the two rows of conductive areas and the two terminal units (i.e., the first terminal unit and the second terminal unit) in the adapter connector. This facilitates the compact layout design of the circuit board 8 and shortens the width of the circuit board 8.

[0084] Specifically, the second direction is horizontal, and the two rows of conductive areas are respectively designated as the first conductive area 81 and the second conductive area 82. The first conductive area 81 is located on the side of the circuit board 8 closest to the adapter connector, and is used for conduction with the fourth connection portion 23 of the second terminal 2. The second conductive area 82 is located on the side of the circuit board 8 furthest from the adapter connector, and is used for conduction 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 below. Figure 10 As shown.

[0085] In some embodiments of this application, please refer to Figure 1 , Figure 6 and Figure 12 The bottom of the first insulating body 4 is provided with a first positioning part 42, and the circuit board 8 is provided with a second positioning part 83 that matches the first positioning part 42. By fitting the first positioning part 42 and the second positioning part 83 together, the assembly positioning between the second connecting part 13 and the second conductive area 82 and between the fourth connecting part 23 and the first conductive area 81 can be realized.

[0086] Specifically, the first positioning part 42 is a positioning post disposed on both sides of the bottom of the first insulating body 4, and the second positioning part 83 is a positioning hole disposed on both sides of the circuit board 8. By inserting the positioning post into the positioning hole on its corresponding side, the assembly positioning between the adapter connector and the circuit board 8 can be achieved.

[0087] In some embodiments of this application, please refer to Figure 6 and Figure 7 The connector assembly also includes a housing assembly 9, which is made of metal and can be used to provide physical protection and electromagnetic shielding for the connector assembly.

[0088] 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. The circuit board 8 is provided with a housing conductive part 84, which can be used to connect with the first housing 91 and 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, which can be used to achieve electromagnetic shielding and installation.

[0089] Please see Figures 1 to 12 In some embodiments of this application, the assembly process of the connector assembly is as follows:

[0090] Step 1: Assemble and position the adapter connector and circuit board 8 through the first positioning part 42 and the second positioning part 83, so that the multiple second connecting parts 13 are connected to the multiple conductive points in the second conductive area 82 on the circuit board 8, and the multiple fourth connecting parts 23 are connected to the multiple conductive points in the first conductive area 81 on the circuit board 8.

[0091] Step 2: The first locking part 41 and the second locking part 72 are used to achieve the assembly positioning between the first insulating body 4 and the second insulating body 7. The first locking part 41 and the second locking part 72 are slid relative to each other in the first direction to achieve the assembly position adjustment between the interface connector and the adapter connector, so that the first elastic part 51 abuts against the first connecting part 11 and the second elastic part 61 abuts against the third connecting part 21.

[0092] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms.
