Description

Technical Field

[0001] This utility model relates to the field of server testing technology, and in particular to an auxiliary connection device. Background Technology

[0002] Existing boundary scan technology is mainly used to inspect the interconnection status of chips and devices on circuit boards, so it is often called boundary scan interconnect (BSI) technology, and the equipment used for this inspection is called BSI equipment. When existing BSI equipment actually inspects the circuit board under test, it typically uses slimline connectors. Slimline connectors are a very common type of connector in servers, and due to their low cost and support for speeds up to 24Gbps, they have become the preferred connector in hard drive-related designs.

[0003] Currently, since the circuit board under test (DUT) in a server cannot be directly connected to the test board, an adapter board is required for auxiliary connection. Typically, the test board is first connected to the adapter board, and then the adapter board connects to the DUT via a Slimline connector. However, due to the very limited internal space of servers, large fixing devices or complex connection methods cannot be accommodated, so a slot-and-plug connection method is used. While this maximizes space utilization, vibrations from the testing environment or equipment can cause the connection between the test board and the adapter board to loosen, affecting the accuracy and stability of the test and increasing the failure rate. Therefore, it is necessary to invent an auxiliary connection device that solves the above-mentioned shortcomings. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary connection device that helps improve the accuracy and stability of testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary connection device is provided for auxiliary connection between an adapter plate and a test plate. The adapter plate is provided with a female connector, and the test plate is provided with a male connector adapted to the female connector. The test plate is installed on the adapter plate by the mating of the male connector and the female connector. The device includes: a first connecting block, which is fixedly mounted on the test plate and has a plurality of first magnets on it, and a positioning pin near the first magnets; and a second connecting block, which is fixedly mounted on the adapter plate and has a plurality of second magnets on it, and a positioning hole for installing the positioning pin is provided on the second connecting block opposite to the positioning pin. When the adapter plate and the test plate are installed together, the first magnets and the second magnets are magnetically connected, and the positioning pin is inserted into the positioning hole.

[0007] Preferably, a connector is electrically connected to one end of the adapter board opposite to the female connector, and the connector is used to connect the adapter board to a port under test of a server under test.

[0008] Preferably, the connector is a Slimline connector.

[0009] Preferably, both the first magnet and the second magnet are cylindrical.

[0010] Preferably, there are four of each of the first and second magnets.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The auxiliary connection device, through the synergistic effect of the first and second connecting blocks, combined with magnetic connection and the cooperation of the positioning pin and the positioning hole, significantly enhances the connection stability between the adapter plate and the test plate, effectively preventing loosening caused by vibration or external force, and reducing the test failure rate. The magnetic attraction of the magnet provides strong connection stability, while the cooperation of the positioning pin and the positioning hole ensures precise alignment and improves connection reliability. In addition, this design simplifies the installation process, allowing for quick connection without complex tools, thus improving work efficiency. The structural design of the device gives it high compatibility and versatility, enabling it to adapt to various devices and interfaces, while reducing manufacturing and maintenance costs and improving equipment safety and service life.

[0018] See Figure 1 and Figure 2 This utility model provides an auxiliary connection device for auxiliary connection between an adapter plate 100 and a test plate 200. The adapter plate 100 is provided with a female connector 101, and the test plate 200 is provided with a male connector 201 adapted to the female connector 101. The test plate 200 is installed on the adapter plate 100 by the mating of the male connector 201 and the female connector 101. Specifically, the main function of the male connector 201 on the test plate 200 is to achieve electrical connection between the test plate 200 and the adapter plate 100 through cooperation with the female connector 101. The pins on the male connector contact the sockets of the female connector to form a stable electrical conduction path, ensuring the transmission of signals and power.

[0019] The auxiliary connection device includes a first connecting block 300 and a second connecting block 400. Firstly, the first connecting block 300 is mounted and fixed on the test plate 200. The first connecting block 300 has multiple first magnets 301 for magnetic connection with the second magnets 401 on the adapter plate 100. Additionally, a positioning pin 302 is provided near the first magnets 301 to further enhance the stability of the connection. The second connecting block 400 is mounted and fixed on the adapter plate 100, and has multiple second magnets 401 corresponding to the first magnets 301 on the test plate 200 for magnetic connection. Simultaneously, a positioning hole 402 is provided on the second connecting block 400 opposite to the positioning pin 302 for mounting the positioning pin 302. When the adapter plate 100 and the test plate 200 are inserted and installed, this ensures that the positioning pin 302 can be accurately inserted, further fixing the relative positions of the adapter plate 100 and the test plate 200. The dual fixing method of magnetic connection and positioning pin 302 significantly enhances the connection stability between adapter plate 100 and test plate 200, effectively reduces the loosening of connection caused by factors such as vibration, thereby improving the stability and reliability of the test.

[0020] In a preferred embodiment, a connector 500 is electrically connected to one end of the adapter board 100 opposite to the female connector 101. The connector 500 is used to connect the adapter board 100 to the port under test of the server under test. Specifically, one end of the adapter board 100 is electrically connected to the female connector 101, and the other end is electrically connected to the connector 500. The connector 500 can be a Slimline connector to achieve the connection with the server. It is mainly electrically connected to the port under test on the server under test, which is actually located on the motherboard under test inside the server under test.

[0021] In another preferred embodiment, both the first magnet 301 and the second magnet 401 are cylindrical. Four of each type are provided. Both the first magnet 301 and the second magnet 401 can be neodymium iron boron magnets, which are the strongest magnets in circulation, possessing excellent coercivity and high magnetic flux density, exhibiting the strongest magnetic force. Furthermore, using four cylindrical magnets can further enhance the magnetic attraction, ensuring the stability and reliability of the connection. It also has advantages such as low cost, ease of manufacturing, and installation. Alternatively, the first magnet 301 and the second magnet 401 do not have to be cylindrical. The specific shape should be chosen based on a comprehensive consideration of factors such as actual application requirements, space constraints, magnetic force requirements, and manufacturing processes. By rationally selecting the magnet shape, the performance of the auxiliary connection device can be optimized.

[0022] In summary, the auxiliary connection device, through the synergistic effect of the first connecting block 300 and the second connecting block 400, combined with the magnetic connection and the engagement of the positioning pin 302 and the positioning hole 402, significantly enhances the connection stability between the adapter plate 100 and the test plate 200, effectively preventing loosening caused by vibration or external force and reducing the test failure rate. The magnetic attraction of the magnet provides strong connection stability, while the engagement of the positioning pin 302 and the positioning hole 402 ensures precise alignment and improves connection reliability. Furthermore, this design simplifies the installation process, allowing for quick connection without complex tools, thus improving work efficiency. The device's structural design gives it high compatibility and versatility, enabling it to adapt to various devices and interfaces, while reducing manufacturing and maintenance costs and improving equipment safety and service life.
