Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a switch using a CPCI connector. Background Technology

[0002] The switch motherboard integrates standard network interfaces (such as RJ45 connectors or pin headers), and uses crimped RJ45 / pin header cables to physically connect the motherboard to external network interfaces. The implementation involves two connection stages: the motherboard side uses a plug-in method (RJ45 or pin header), and the external interface side uses manual soldering to complete the electrical connection between the cable and the interface. To ensure cable stability, additional cable routing aids are required for securing the cables.

[0003] The main defects of the existing technology are as follows: 1. Mechanical structural defects: The lack of a dedicated fixing mechanism makes the motherboard interface (RJ45 / pin header) and cable connection points susceptible to vibration, which can lead to poor contact over long-term use; the connection between the cable and the motherboard lacks an anti-detachment design, resulting in poor physical stability; 2. Process reliability risks: External interface terminals rely on manual soldering, and operational errors can easily lead to incorrect soldering / cold soldering. Soldering quality is greatly affected by the skill level of the personnel, making it difficult to guarantee consistency. These problems directly lead to the risk of network communication interruption, affecting the core functions of the equipment; 3. High manufacturing complexity: Multi-port devices require soldering wire by wire, and the number of solder points on a single device increases exponentially with the number of ports. The production process requires repeated verification of electrical wiring diagrams, resulting in high labor costs and a high risk of errors; 4. Difficult internal cable management: Discrete cables require additional fixing devices, increasing BOM costs and assembly steps. Messy cable bundles affect equipment heat dissipation and subsequent maintenance, and increase the difficulty of troubleshooting.

[0004] Existing technologies are no longer sufficient to meet the requirements of high-reliability industrial switches for connection stability and mass production efficiency, and there is an urgent need to improve them through integrated connection solutions. Utility Model Content

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within its scope.

[0026] In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, a switch using a CPCI connector is provided, such as... Figure 1-4 As shown, it includes:

[0027] Switching motherboard module 1, which is equipped with CPCI connector 104;

[0028] Network interface circuit board module 2, which is equipped with CPCI socket 201, and CPCI plug 104 is connected to CPCI socket 201.

[0029] The network connector module 3 is equipped with multiple network connectors 301, which are connected and soldered to multiple connector packages 202 on the network interface circuit board module 2 via corresponding pins.

[0030] Specifically, in the traditional method, the network interface on the switching motherboard usually uses RJ45 or pin header sockets. Then, a crystal head or pin header is crimped onto one end of the cable and inserted into the corresponding RJ45 or pin header socket. The other end of the cable is soldered to the corresponding external network interface (such as a network connector). When soldering, it is necessary to repeatedly check the electrical wiring diagram to confirm the correspondence between the external network interface and the network interface on the switching motherboard. This can easily lead to many problems such as connection errors, cold solder joints, loose connections, and poor contact.

[0031] In this embodiment, a network interface circuit board module 2 is set between the switching motherboard module 1 and the external network interface (network connector module 3 is used in this embodiment) to replace the traditional cable connection method, thus avoiding many problems that may occur with the traditional cable method.

[0032] CPCI plugs 104 and CPCI sockets 201 are respectively set on the switching motherboard module 1 and the network interface circuit board module 2 and are connected accordingly, eliminating the need for cable connection in traditional technology, as well as crimping crystal heads and soldering. The network interface circuit board module 2 includes a network interface circuit board 202, which has multiple aviation plug packages 203. The pins of the CPCI socket 201 are formed on the copper foil lines on the substrate (such as FR-4) through an etching process, which undertake the electrical connection function between components. This also avoids the problems of lack of fixing device for external wiring and unstable connection.

[0033] Multiple network connectors 301 on the network connector module 3 and multiple connector packages 203 on the network interface circuit board 202 are first inserted by corresponding pins, and then connected and fixed by soldering to achieve dual protection.

[0042] In a preferred embodiment of the present invention, a plurality of fins 1031 are provided on one side of the cold plate 103.

[0043] Specifically, in this embodiment, the switching motherboard 101 usually generates a lot of heat during network switching. In order to improve the heat dissipation effect, a cold plate is installed on the switching motherboard 101 to assist in heat dissipation. A thermally conductive silicone pad is attached between the heat-generating part of the switching motherboard 101 and the cold plate 103 to enhance the heat conduction effect. Multiple fins are added to one side of the cold plate to increase the heat dissipation area and further improve the heat dissipation effect.

[0044] In a preferred embodiment of the present invention, the switch chassis 4 is further included, and the switch motherboard module 1 also includes a mounting plate 102, which is screwed into the switch chassis 4.

[0045] Specifically, the switch chassis 4 is provided with an external barrier to reduce the impact of the external environment. A mounting plate 102 is provided, and the switch motherboard 101 is screwed to the mounting plate 102 to fix the switch motherboard module 1, the network interface circuit board module 2 and the network connector module 3 in the switch chassis 4.
