Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a novel PCIE electrical connector. Background Art

[0002] The PCIE electrical connector is based on the PCI Express bus standard and is a high-speed serial computer expansion bus interface. It uses a point-to-point serial connection method, and each device has its own independent data connection without affecting each other, thus providing high-bandwidth and low-latency data transmission performance. The PCIE electrical connector contains multiple differential signal line pairs for data transmission, clock synchronization, and reset functions. The differential signal line pair consists of two signal lines, D+ and D-, and the difference between the two signals is compared to determine whether the logic "1" or the logic "0" is sent. This differential signal method effectively improves the signal's anti-interference ability and transmission rate.

[0003] After searching, the patent with patent announcement number CN202323015339.2 discloses a PCIE electrical connector that can be plugged on both sides. Although the device is provided with a plastic body, fixed feet arranged at both ends of the plastic body and a plurality of signal terminals inserted on both sides of the plastic body when in use, the interior of the plastic body is provided with a slot that passes through from top to bottom and can be inserted with a card, and the slot is provided with a first socket for inserting a network card from the top of the plastic body and a second socket for inserting a network card from the bottom of the plastic body, and both sides of the plastic body are provided with horizontal mounting surfaces that are installed in cooperation with the PCB board, the first socket and the second socket have the same structure and are distributed on both sides of the PCB board, and the network card selectively inserts from the first socket or the second socket and abuts against the signal terminal to realize signal transmission, but when the device is in use, the structure of the PCIe electrical connector is that all single contacts are bridged together, resulting in excessive signal interference when the high-speed transmission terminal transmits high-speed signals in the high-frequency band, which fails to meet the high-speed transmission requirements of PCIe6.0. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a novel PCIE electrical connector, which solves the problems raised in the background technology.

[0005] The solution of the present invention to solve the above technical problems is as follows:

[0006] A novel PCIE electrical connector comprises a plastic body, a molded terminal is installed in the plastic body, and a metal conductive bridge is installed in the molded terminal;

[0007] The molded terminal is plugged with a first spring, and both ends of the molded terminal are provided with fixing plates, and the molded terminal is installed on the circuit main board through the fixing plates. One end of the molded terminal is provided with a second buckle, and the metal conductive bridge is mounted in the molded terminal through the second buckle;

[0008] The metal conductive bridge is provided with a connecting rib, and the upper end and the lower end of the connecting rib are respectively provided with a third reed and a second reed, and the third reed and the second reed are both in electrical contact with the first reed.

[0016] Furthermore, the molded terminal is provided with a first buckle, and the plastic body is provided with a card interface. The molded terminal is mutually engaged with the card interface through the first buckle, so that the plastic body and the molded terminal are connected and fixed.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The first buckle on the molded terminal and the card interface on the plastic body are mutually engaged, thereby achieving a stable connection between the plastic body and the molded terminal.

This design not only prolongs the service life of the first reed, but also ensures good contact between the first reed and the circuit board, thereby ensuring stable transmission of electrical signals.

[0022] Furthermore, a notch is provided on the metal conductive bridge piece. When the metal conductive bridge piece is installed in the molded terminal, the metal conductive bridge piece is adjusted through the notch so that the metal conductive bridge piece fits the molded terminal.

[0023] The beneficial effects of adopting the above further scheme are:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 4As shown, the embodiments provided by the present invention are:

[0042] Embodiment 1

[0043] A novel PCIE electrical connector includes a plastic body 1, a molded terminal 2 is installed in the plastic body 1, a first buckle 202 is provided on the molded terminal 2, a card interface 104 is provided on the plastic body 1, the molded terminal 2 is mutually engaged with the card interface 104 through the first buckle 202, the plastic body 1 is connected and fixed with the molded terminal 2, and the first buckle 202 on the molded terminal 2 and the card interface 104 on the plastic body 1 are cleverly matched to achieve a stable connection between the two. This snap-on method is not only simple and easy, without the need for complicated installation steps or tools, but also can effectively resist vibration and impact. In actual use, no matter how large the vibration or impact is, the buckle and the card interface 104 can be tightly engaged together to ensure that the connection between the plastic body 1 and the molded terminal 2 will not loosen or break. This stable connection method greatly prolongs the service life of the electrical connector and ensures its stability and reliability in long-term use. A metal conductive bridge 3 is installed in the molded terminal 2, and a notch 302 is provided on the metal conductive bridge 3. During the installation of the metal conductive bridge 3 in the molded terminal 2, the metal conductive bridge 3 is adjusted through the notch 302 to make the metal conductive bridge 3 fit the molded terminal 2. The notches 302 specially provided on the metal conductive bridge 3 provide great flexibility during the installation process. These notches 302 not only allow the bridge to be adjusted within a certain range during the installation process to adapt to the size of the molded terminal 2, but also ensure close contact and good conductivity between the bridge and the molded terminal 2. In the actual installation process, the notch 302 on the bridge is adjusted to ensure a perfect match between it and the molded terminal 2. This design not only increases the flexibility of installation, but also avoids the problem of unstable or interrupted transmission of electrical signals due to mismatching, thereby improving the overall performance and reliability of the electrical connector. The metal conductive bridge 3 is provided with a fixing hole 301, and the metal conductive bridge 3 is installed on the circuit main board through the fixing hole 301. The fixing holes 301 specially opened on the metal conductive bridge 3 provide great convenience for its connection with the circuit main board. These fixing holes 301 are not only designed just right, so that the bridge can be firmly installed on the main board, but also greatly simplify the installation process and improve work efficiency. The installer does not need to spend too much time and energy to find a suitable connection point or perform complicated fixing operations. It only needs to align the fixing holes 301 on the bridge with the corresponding holes on the main board, and then use appropriate fasteners to fix them. This design not only ensures a firm connection between the metal conductive bridge 3 and the circuit main board, but also avoids the problem of unstable or interrupted transmission of electrical signals due to loose connection, thereby ensuring the stable transmission of electrical signals.

[0044] Embodiment 2

[0045] In order to significantly reduce the degree of signal interference attenuation caused by high-speed transmission terminals when transmitting high-speed signals in high-frequency bands, and to improve the effective signal transmission speed of electronic devices, for example, Figures 1 to 4 As shown, the present invention also includes: a first spring 203 is plugged into the molded terminal 2, a socket 102 is provided on the plastic body 1, a limit block 101 is provided in the socket 102, the socket 102 is divided into two parts by the limit block 101, and the first spring 203 on the molded terminal 2 is also provided with two parts, and the two parts of the first spring 203 correspond to the positions of the socket 102. This clever design cleverly divides the socket 102 into two parts, each of which closely corresponds to the two parts of the first spring 203 carefully arranged on the molded terminal 2. The limit block 101 not only plays a separating role, but more importantly, it ensures the accuracy and stability of the first spring 203 during the installation process. Each spring can be accurately placed in the corresponding part of the socket 102, avoiding any possible offset or misalignment. This not only makes the installation process smoother, but also greatly reduces the risk of damage to the spring during installation or subsequent use. This precise alignment and stable installation method undoubtedly improves the overall performance and reliability of the electrical connector and provides a solid foundation for the stable transmission of electrical signals. A groove 103 is provided in the socket 102, and the end of the first reed 203 is located in the groove 103. The end of the first reed 203 is protected by the groove 103. The groove 103 carefully provided in the socket 102 provides all-round protection for the end of the first reed 203. These grooves 103 are not only designed to be just right, and can tightly wrap the end of the reed, but also prevent the reed from being damaged or deformed in any form during use. This design not only extends the service life of the first reed 203, but also ensures good contact between the reed and the circuit board. The end of the reed is always kept in the groove 103, and will not be displaced or deformed due to external factors, thereby ensuring the stable transmission of electrical signals. In addition, the design of the groove 103 also increases the friction between the reed and the socket 102, so that the reed is more firmly fixed in the socket 102, further improving the overall performance and reliability of the electrical connector. Fixed plates 201 are provided at both ends of the molded terminal 2, and the molded terminal 2 is installed on the circuit main board through the fixed plate 201. A second clip 204 is provided at one end of the molded terminal 2, and the metal conductive bridge 3 is installed in the molded terminal 2 through the second clip 204. The metal conductive bridge 3 is provided with a connecting rib 304, and the upper and lower ends of the connecting rib 304 are respectively provided with a third reed 305 and a second reed 303, and the third reed 305 and the second reed 303 are both in electrical contact with the first reed 203.

[0046] Working principle:

[0047] The molded terminal 2 is connected to the card interface 104 on the plastic body 1 by the first clip 202 thereon to achieve a stable connection. This card connection method is not only simple and easy, but also can resist vibration and impact, ensuring the stability of the electrical connector in long-term use. The metal conductive bridge 3 is installed on the circuit board through the fixing hole 301 thereon, and is connected to the molded terminal 2 by the second clip 204. This installation method not only ensures the close contact between the metal conductive bridge 3 and the molded terminal 2, but also provides additional fixing support, thereby enhancing the stability of the electrical connector.

[0048] The first spring piece 203 inserted on the molded terminal 2 is in electrical contact with the third spring piece 305 and the second spring piece 303 on the metal conductive bridge 3. This contact mode ensures that the electrical signal can be smoothly transmitted between the spring piece and the metal conductive bridge 3, thereby realizing high-speed data transmission. When the electrical signal is transmitted from the circuit board to the electrical connector, it will first enter the metal conductive bridge 3 through the metal connector at the fixing hole 301 on the metal conductive bridge 3. Then, the electrical signal will be transmitted through the third spring piece 305 and the second spring piece 303 on the metal conductive bridge 3 and the first spring piece 203. Finally, the electrical signal will be transmitted to the molded terminal 2 through the first spring piece 203, and finally transmitted to the peripheral device or expansion card connected to the electrical connector.

[0049] The groove 103 provided in the socket 102 protects the end of the first reed 203 from being damaged or deformed. This design ensures the reliability and stability of the reed in long-term use. The groove 103 provided in the socket 102 protects the end of the first reed 203 from being damaged or deformed. This design ensures the reliability and stability of the reed in long-term use.
