Abstract
Description
Technical Field
[0001] The present application relates to the field of connectors, and particularly to a high-speed electrical connector and its assembly process. Background Art
[0002] A high-speed electrical connector is an electronic component designed to transmit high-frequency signals, usually used for signal transmission inside or between electronic devices.
[0003] In related technologies, referring to Figure 1 and Figure 2 , the high-speed electrical connector includes a housing 1 and a plurality of terminal inserts installed in the housing 1. The housing 1 is provided with an insertion port 11 for other connectors to be inserted and mated, an installation port 12 for each terminal insert to be loaded into the housing 1, and a connection port 13 for each terminal insert to be connected to a circuit board. The connection port 13 is opened on the bottom wall of the housing 1, and the insertion port 11 and the installation port 12 are oppositely arranged. One end of each terminal insert faces the insertion port 11, and the other end of each terminal insert extends out of the housing 1 through the connection port 13 to facilitate the connection of each terminal insert to the circuit board.
[0004] The terminal inserts are divided into a first terminal insert 2, a second terminal insert 3, a third terminal insert 4, and a fourth terminal insert 5. Limited by the shapes of different terminal inserts, during installation, they are usually loaded into the housing 1 in the arrangement order of the first terminal insert 2, the second terminal insert 3, the third terminal insert 4, and the fourth terminal insert 5 through the installation port 12 along the arrangement direction from the installation port 12 to the insertion port 11.
[0005] The housing 1 loaded with each terminal insert is supported by each terminal insert, and its structural strength relatively meets the application requirements. For the housing 1 without loading each terminal insert, in order to enable each terminal insert to be smoothly loaded into the housing 1 and meet the requirement that the end of each terminal insert leaks out through the connection port 13, the connection port 13 is completely communicated with the installation port 12, and there is a large-distance gap between the two opposite shell walls of the housing 1 surrounding the connection port 13, resulting in low strength of the housing 1. It is not only easy to be damaged when suffering impacts, but also has a relatively high defective rate in direct molding, which needs to be improved. Summary of the Invention
[0006] In order to improve the yield rate of the housing, the present application provides a high-speed electrical connector and its assembly process.
[0007] In the first aspect, a high-speed electrical connector provided by the present application adopts the following technical solution:
[0008] A high-speed electrical connector includes a shell having a connection port connected to its own inner cavity, two opposite shell walls of the shell used to enclose the connection port being connecting walls, a reinforcement strip connected to both connecting walls being provided between the two connecting walls, and the reinforcement strip being integrally formed with the shell.
[0009] By adopting the above technical solution, a reinforcement strip is directly integrally formed when the shell is formed, and the reinforcement strip is located between the two connecting walls and supports the two connecting walls, which can effectively prevent the two connecting walls from being damaged or forming defective products due to impact, thereby effectively improving the yield of the shell.
[0010] Optionally, it also includes a first terminal insert and a second terminal insert arranged in the shell, and the shell is provided with a loading groove on the surface of the connection port, and a sliding groove connected to the loading groove is provided on the connecting wall. The loading groove and the sliding groove are both used for inserting and sliding the ends of the first terminal insert and the second terminal insert, and the first terminal insert and the second terminal insert can both slide in the sliding groove to the position where they are installed.
[0011] By adopting the above technical solution, when installing the first terminal insert and the second terminal insert, the end of the first terminal insert is first inserted into the sliding groove through the insertion groove, and then the first terminal insert is slid to the position where it is installed. Then, the end of the second terminal insert is inserted into the sliding groove through the insertion groove, and finally the second terminal insert is slid to the position where it is installed.
[0012] Alternatively, the second terminal insert may be first installed into the sliding slot through the installation slot, and then the second terminal insert may be slid until it is offset from the installation slot to make way for the first terminal insert. The first terminal insert may then be installed, and finally the second terminal insert may be slid to a position where it is fully installed.
[0013] With this arrangement, both the first terminal insert and the second terminal insert can be installed into the housing through the connection port without being installed through the installation port. The addition of a reinforcement strip on the housing will not affect the installation of the first terminal insert and the second terminal insert. The installation method is simple and can be easily achieved through automation.
[0014] Optionally, it also includes a first stop block connected to the shell, the shell is provided with a plug interface for inserting other connectors, the first stop block is located on the side of the first terminal insert away from the plug interface, and the first stop block is in conflict with the first terminal insert, the first stop block is provided with a limiting groove for inserting the second terminal insert, and the direction of the second terminal insert inserted into the limiting groove is staggered with the extension direction of the plug interface.
[0015] By adopting the above technical solution, after the first and second terminal inserts are installed, the first stopper is installed on the housing. The first stopper blocks the first terminal insert, effectively improving its structural stability and minimizing its movement when other connectors are inserted into the plug interface and mated with the first terminal insert. Secondly, the first stopper limits the second terminal insert via the limiting groove, similarly effectively restricting its movement along the extension direction of the plug interface and improving its structural stability.
[0016] Optionally, it also includes a third terminal insert and a second stop block connected to the shell, the second stop block is provided with a limiting boss and a fixed plug, the surface of the limiting boss facing the plug interface is in contact with the second terminal insert, the third terminal insert is provided with a fixed slot, and the direction in which the fixed plug is inserted into the fixed slot is staggered with the extension direction of the plug interface.
[0017] By adopting this technical solution, after installing the second and third terminal inserts, the second stopper is installed on the housing. The limiting boss blocks the second terminal insert, restricting its movement away from the plug interface, thereby improving its stability when other connectors are inserted into the plug interface. Furthermore, the fixing slot and the fixing block cooperate to effectively improve the structural stability of the third terminal insert after installation in the housing.
[0018] Optionally, the first stopper is made of a wave-absorbing material or a conductive material, and the second stopper is made of a wave-absorbing material or a conductive material.
[0019] By adopting the above technical solution, the first and second blocks made of absorbing material can effectively absorb noise waves generated by the first and second terminal inserts. The first and second blocks made of conductive material can effectively isolate noise and suppress adjacent electromagnetic waves. Therefore, using absorbing or conductive materials as the materials for the first and second blocks can improve the high-frequency performance of the connector of this application.
[0020] Optionally, a third terminal insert is further included in the housing, and an insertion groove is provided on the surface of the housing where the connection port is provided, and an end of the third terminal insert is inserted into the insertion groove.
[0021] By adopting the above technical solution, when installing the third terminal insert, the third terminal insert is installed into the housing through the connection port and simultaneously inserted into the insertion slot. This arrangement eliminates the need for the third terminal insert to be installed through the installation port, i.e., the installation of the third terminal insert is not restricted by the reinforcement strip.
[0022] Optionally, it further includes a first terminal insert, a second terminal insert, a first stopper for limiting the first terminal insert and the second terminal insert, a second stopper for limiting the second terminal insert and the third terminal insert, and a riveting piece provided on the outer wall of the housing. A connecting post is provided on the housing. The first stopper, the second stopper, the third terminal insert, and the connecting post all penetrate through the riveting piece. A riveting head is connected to one side of the first stopper, the second stopper, the third terminal insert, and the connecting post away from the inner cavity of the housing. The riveting head abuts against the surface of the riveting piece away from the inner cavity of the housing.
[0023] By adopting the above technical solution, after the first terminal insert, the second terminal insert, the third terminal insert, the first stopper, and the second stopper are all installed, the riveting piece is sleeved on the first stopper, the second stopper, the third terminal insert, and the connecting post, that is, the first stopper, the second stopper, the third terminal insert, and the connecting post penetrate through the riveting piece. Then, hot riveting is performed on the first stopper, the second stopper, the third terminal insert, and the connecting post, so that riveting heads are formed on the first stopper, the second stopper, the third terminal insert, and the connecting post. The first stopper, the second stopper, the third terminal insert, and the connecting post are fixed by the riveting heads and the riveting piece. The connection method is simple and can fix the first stopper, the second stopper, the third terminal insert, and the riveting piece at the same time.
[0024] In a second aspect, the present application provides an assembly process for a high-speed electrical connector adopting the following technical solution:
[0025] An assembly process for a high-speed electrical connector is applied to a high-speed electrical connector. The high-speed electrical connector further includes a fourth terminal insert. An insertion groove is formed on the surface of the housing provided with a connection port. An installation port is formed on the housing opposite to the insertion port. A connection groove communicating with the installation port is formed on the connection wall. The process includes the following steps:
[0026] Installation of the fourth terminal insert: The fourth terminal insert is inserted into the housing through the installation port, and the fourth terminal insert is inserted into the connection groove.
[0027] Installation of the third terminal insert: The third terminal insert is inserted into the housing through the connection port, and the third terminal insert is inserted into the insertion groove.
[0028] Installation of the first terminal insert: The first terminal insert is inserted into the housing through the connection port. The first terminal insert is first inserted into the loading groove, then moved into the sliding groove, and finally moves to its installation position in the sliding groove.
[0029] Installation of the second terminal insert: The second terminal insert is inserted into the housing through the connection port. The second terminal insert is first inserted into the loading groove, then moved into the sliding groove, and finally moves to its installation position in the sliding groove.
[0030] By adopting the above technical solution, even if a reinforcement strip is added to the housing, the installation of the fourth terminal insert is not affected and can be installed using existing methods. The first, second, and third terminal inserts are all installed through the connection port, avoiding the reinforcement strip, and can still be installed normally. In this arrangement, while the reinforcement strip is integrally formed on the housing to increase the housing strength, the first, second, third, and fourth terminal inserts can be installed smoothly by changing the housing structure and installation method. This means that the housing's yield rate is improved while ensuring normal connector production.
[0031] Optionally, a stopper groove communicating with the sliding groove is provided on the surface of the housing provided with the connection port, and a stopper hole is provided on the housing, further comprising the following steps:
[0032] Installation of the second stopper: The second stopper is installed into the housing through the stopper hole, and the surface of the limiting boss facing the plug interface contacts the second terminal insert. The third terminal insert is provided with a fixing slot, and the direction in which the fixing insert is inserted into the fixing slot is staggered with the extension direction of the plug interface.
[0033] Installation of the first stopper: Install the first stopper into the housing through the connection port, install the first stopper into the stopper groove, and the first stopper is located between the first terminal insert and the second terminal insert, and the second terminal insert is inserted into the limiting groove.
[0034] By adopting the above technical solution, the first stopper not only simultaneously limits and reinforces the first and second terminal inserts, but also facilitates installation. The second stopper is also easy to install and simultaneously limits and reinforces the second and third terminal inserts. The first and second stops not only enhance the structural strength of the connector of this application but also improve the insertion stability of the first, second, and third terminal inserts when mating with other connectors.
[0035] Optionally, the housing is provided with a connecting column and a riveting sheet, and the riveting sheet is provided with through holes corresponding to the connecting column, the first stopper, the second stopper and the third terminal insert, and further comprising the following steps:
[0036] Hot riveting process: The rivet sheet is installed on the shell, and the connecting column, the first stop block, the second stop block and the third terminal insert are respectively inserted into different through holes, and the ends of the connecting column, the first stop block, the second stop block and the third terminal insert passing through the through holes are hot riveted to form rivet heads on the ends of the connecting column, the first stop block, the second stop block and the third terminal insert.
[0037] By adopting the above technical solution, compared with other methods, hot riveting can fix the first stop block, the second stop block, and the third terminal insert at the same time, and cooperate with the connecting column to also fix the riveting sheet on the housing. The process is simple, fast, and has high strength, meeting the strength requirements of the connector in this application.
[0038] In summary, this application includes at least one of the following beneficial technical effects:
[0039] Reinforcing strips for supporting two connecting walls are formed on the housing, which can significantly improve the structural strength of the housing, minimize the damage of the connecting walls due to external impacts or the formation of defective products, and effectively improve the yield rate of the housing;

Through the reinforcing strips, the different CTE parameters of different materials and the thermal deformation during surface mounting in the IR furnace can be effectively resisted. At the same time, the holding strength between the first terminal insert, the second terminal insert, the third terminal insert, and the fourth terminal insert is improved, and the distance accuracy of the first terminal insert, the second terminal insert, the third terminal insert, and the fourth terminal insert after installation is improved, thereby improving the high-frequency performance.

[0057] Refer to Figure 4-6 , a bottom locking block 51 and two side locking blocks 52 are integrally formed on the fourth terminal insert 5, and the two side locking blocks 52 are respectively located on both sides of the fourth terminal insert 5. Connecting grooves 142 are formed on the opposite surfaces of the two connecting walls 14, and side locking grooves 143 are formed on the groove walls of the connecting grooves 142. The two connecting grooves 142 are respectively used for inserting and sliding different side locking blocks 52, and the two side locking grooves 143 are respectively used for engaging and cooperating with different side locking blocks 52. A bottom locking groove 16 is formed on the inner wall of the housing 1, and the bottom locking groove 16 is used for engaging and cooperating with the bottom locking block 51. When the bottom locking groove 16 engages and cooperates with the bottom locking block 51, the side locking groove 143 engages and cooperates with the corresponding side locking block 52, and at this time, the fourth terminal insert 5 is completely installed in place.
[0058] Refer to Figure 4-6 , when installing the fourth terminal insert 5, first insert the fourth terminal insert 5 into the housing 1 through the installation port 12, insert the guide block 21 on the fourth terminal insert 5 into the corresponding guide groove 141, and then slide the fourth terminal insert 5 until the side locking block 52 engages and cooperates with the side locking groove 143 and the bottom locking block 51 engages and cooperates with the bottom locking groove 16.
[0059] Refer to Figure 4-6 , two insertion slots 144 are formed on the surface of the housing 1 provided with the connection port 13, and the two insertion slots 144 are respectively located on different connecting walls 14. Both ends of the third terminal insert 4 are in a block shape and are respectively inserted into different insertion slots 144. A mating groove 41 is formed on the side of the third terminal insert 4 facing the fourth terminal insert 5, and a reinforcing post 42 is integrally formed on the groove wall of the mating groove 41. A mating protrusion 53 is formed on the fourth terminal insert 5, the mating groove 41 is used for inserting the mating protrusion 53, and a reinforcing groove 54 for inserting the reinforcing post 42 is formed on the mating protrusion 53. When the third terminal insert 4 is inserted into the insertion slot 144, the mating protrusion 53 is inserted into the mating groove 41 and the reinforcing post 42 is inserted into the reinforcing groove 54.

[0061] Refer toFigure 4 , Figure 5 , on the surface of the housing 1 provided with the connection port 13, two insertion grooves 145 are formed. The two insertion grooves 145 are respectively located on different connection walls 14. The insertion grooves 145 are used for the ends of the first terminal insert 2 and the second terminal insert 3 to be inserted and slide. On the opposite surfaces of the two connection walls 14, sliding grooves 146 are formed. The sliding grooves 146 are divided into a first sliding groove 1461 and a second sliding groove 1462 communicating with the first sliding groove 1461 along their own extending directions. The first sliding groove 1461 and the second sliding groove 1462 are arranged along the arrangement direction from the insertion port 11 to the installation port 12. The groove width of the second sliding groove 1462 is greater than that of the first sliding groove 1461. The second sliding groove 1462 communicates with the insertion groove 145 and is used for the ends of the first terminal insert 2 and the second terminal insert 3 to be inserted and slide. The first sliding groove 1461 is used for the end of the first terminal insert 2 to be inserted and slide. When the first terminal insert 2 slides to the end of the first sliding groove 1461 far from the second sliding groove 1462, it is the installation completion position of the first terminal insert 2. When the second terminal insert 3 slides to the end of the second sliding groove 1462 close to the first sliding groove 1461, it is the installation completion position of the second terminal insert 3.

In this case, the second terminal insert 3 can be installed first, and the second terminal insert 3 is moved away from the first sliding groove 1461 to make way, so that the end of the first terminal insert 2 can be inserted into the second sliding groove 1462 through the insertion groove 145. Then install the first terminal insert 2 first, and then install the second terminal insert 3. With such a setting, the second terminal insert 3 and the first terminal insert 2 can be inserted into the second sliding groove 1462 first, and then pushed together to complete the installation together.

The third terminal insert 4 is provided with a fixed slot 43. The extension direction of the fixed slot 43 is perpendicular to the extension direction of the plug port 11, that is, the extension direction of the fixed slot 43 is perpendicular to the direction in which other connectors are inserted into the plug port 11. The fixed insert 72 is inserted into the fixed slot 43, and the direction in which the fixed insert 72 is inserted into the fixed slot 43 is staggered with the extension direction of the plug port 11.

Then, insert the first stopper 6 into the housing 1 through the stopper groove 148, and insert the second terminal insert 3 into the limiting groove 61. In other embodiments, the first stopper 6 can also be installed first, and then the second stopper 7.
[0068] Reference Figure 7 Figure 7 , on the opposite surfaces of the two connecting walls 14, riveting grooves 149 are integrally formed. Riveting sheets 8 are placed in each of the riveting grooves 149. Connecting columns 17 are integrally formed on the groove walls of the riveting grooves 149. A plurality of through holes 81 are formed in the riveting sheets 8, and the end portions of the connecting columns 17, the first stopper 6, the second stopper 7, and the third terminal insert 4 are respectively adapted to pass through the respective through holes 81.

Then, hot riveting is performed on the first stopper 6, the second stopper 7, the third terminal insert 4, and the connecting column 17 to form the riveting head 171, thereby fixing the riveting sheet 8 on the housing 1 and fixing the first stopper 6, the second stopper 7, and the third terminal insert 4 on the riveting sheet 8 and the housing 1.
[0070] Reference Figure 3 Figure 3 , on the surface of the housing 1 provided with the connection port 13, two mounting posts 18 are integrally formed. A welding fixing piece 9 is disposed on the mounting posts 18. The mounting posts 18 pass through the welding fixing piece 9, and both ends of the welding fixing piece 9 are in snap-fit engagement with the housing 1. The welding fixing piece 9 is used for welding with the PCB pad to make the connector of the present application more firmly welded.
[0071] The implementation principle of a high-speed electrical connector according to an embodiment of the present application is as follows: Even if a reinforcing bar 15 is integrally formed on the housing 1, by providing the insertion slot 144, the loading slot 145, and the sliding slot 146, the first terminal insert 2, the second terminal insert 3, and the third terminal insert 4 can still be smoothly installed.
