[0025] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] This embodiment provides a computer automatic electrical testing device, such as Figure 1-6 As shown, it includes an upper test component and a lower test component, the lower test component includes a lower circuit board 1, a probe 2 and a lower network cable female connector 3, the upper end of the probe 2 extends upward from the upper surface of the lower circuit board 1, the probe 2 is welded to the lower circuit board 1, and the lower network cable female connector 3 is arranged on the lower surface of the lower circuit board 1, the upper test component includes an upper circuit board 4, a probe contact point 5 and an Internet cable female connector 6, the probe contact point 5 is arranged corresponding to the probe 2, the probe contact point 5 is welded to the lower surface of the upper circuit board 4, the Internet cable female connector 6 is arranged on the upper surface of the upper circuit board 4, the probe 2 is selectively contacted with the probe contact point 5, and the selective contact means that in the non-working test state, the probe and the probe contact point are not in contact, and in the working test state, the probe and the probe contact point are in contact, the lower circuit board and the upper circuit board can be treated with anti-interference, the anti-interference treatment belongs to the prior art, and does not belong to the innovation of the present application, so it will not be repeated here. In this embodiment, the probe is directly welded to the lower circuit board after anti-interference treatment, and the network cable is inserted into the lower network cable female connector, avoiding the welding of the network cable and the probe, and solving many problems such as easy oxidation at the welding point between the network cable and the probe, large resistance of solder joint burrs, weakened anti-interference ability of the twisted pair network cable when separated during welding, and time-consuming and costly welding. The network quality is greatly improved, and the network transmission speed reaches gigabit (1000Mbps), meeting the test requirements.

[0027] In order to protect the probe, the present embodiment further includes a lower fixing plate 7 and a probe protection seat 8. The lower circuit board 1 is installed in the middle of the lower fixing plate 7. The probe protection seat 8 is arranged above the lower circuit board 1. A vertical through hole is arranged on the probe protection seat 8. The upper end of the probe 2 extends into the through hole. The probe protection seat 8 can slide up and down relative to the probe 2. An elastic member 9 is arranged between the probe protection seat 8 and the lower fixing plate 7. When not in operation, the probe is located in the through hole of the probe protection seat, which can effectively protect the probe from external damage. When in operation, a downward force is applied to the probe protection seat to expose the probe, and the probe can work by contacting the probe contact point. Due to the setting of the elastic member, the elastic member is compressed when in operation, and the downward force is removed when not in operation. Under the elastic action of the elastic member, the probe protection seat can automatically reset to continuously protect the probe.

[0028] The present embodiment also includes an upper mounting plate 10, on which the upper circuit board 4 is mounted, and the upper mounting plate 10 is selectively placed above the probe protection seat 8. In the present embodiment, the force applied to the probe protection seat comes from the gravity of the upper mounting plate and the upper test assembly. The upper test assembly is assembled with the upper mounting plate in advance, a network cable is inserted into the lower network cable female connector, one end of the other network cable is inserted into the upper network cable female connector, and the other end is inserted into the desktop host. The upper mounting plate is automatically placed on the probe protection seat by a manipulator. Due to the gravity of the upper mounting plate and the upper test assembly, the probe protection seat moves downward, and the probe is exposed to contact with the probe contact point to perform the test. After the test is completed, the upper mounting plate is removed. Due to the compression of the elastic member, the elastic member drives the probe protection seat to move upward and reset, thereby protecting the probe.

[0029] In order to prevent the probe protection seat from moving upwards uncontrollably when resetting due to the elastic force of the elastic member, the present embodiment further includes a fixed panel 11, which is arranged on both sides of the lower fixed plate 7. The inner side of the fixed panel 11 is provided with a limit portion 12 protruding inwards, and the outer side of the probe protection seat 8 is correspondingly provided with a flange 13 protruding outwards. In the non-working state, that is, in the free state of the elastic member, the lower surface of the limit portion contacts the upper surface of the flange, and this arrangement can ensure that the probe protection seat can be completely reset and can prevent the probe protection seat from continuing to move upward.

[0030] Specifically, the lower ends of the lower network cable female connector and the probe 2 extend into the lower fixing plate 7, a first groove 14 is provided in the middle of the upper surface of the lower fixing plate 7, and the lower circuit board 1 is installed in the first groove 14 by screws. The first groove is provided with corresponding through grooves for the probe and the lower network cable female connector on the lower side of the lower circuit board. The network cable can be inserted into the lower network cable female connector through the through groove.

[0031] Optionally, the elastic member 9 is a spring, and a second groove 15 is provided on both sides of the first groove 14, and downward protrusions 16 are provided on both sides of the lower end of the probe protection seat 8, and a third groove 17 opposite to the second groove 15 is provided on the protrusion 16, and one end of the spring is connected to the second groove 15, and the other end of the spring is connected to the third groove 17. The downwardly arranged protrusion 16 can limit the downward movement distance of the probe protection seat, and prevent the spring from being overly compressed and affecting the life of the spring. Optionally, the flange 13 is arranged on the outer side of the protrusion 16.

[0032] Optionally, a vertical threaded hole is provided on the lower surface of the fixed panel 11, and a stepped hole is correspondingly provided on the lower fixed plate 7, the stepped hole including a small hole 18 and a large hole 19 from top to bottom, and a screw is inserted into the stepped hole and threadedly connected with the threaded hole. After installation, the screw is located in the large hole, so that the lower surface of the lower fixed plate is flat, which is convenient for placing the lower fixed plate.

[0033] Optionally, a fourth groove 20 and a fifth groove 21 are provided in the middle of the upper mounting plate 10 from bottom to top. The fourth groove 20 is used to install the second circuit board, and the fifth groove 21 is used to place the network cable female connector. The network cable is inserted into the network cable female connector through the fifth groove.

[0034] Optionally, two lower network cable female connectors are provided on the lower circuit board 1, and two upper network cable female connectors are provided on the upper circuit board 4, and each upper network cable female connector corresponds to the lower network cable female connector directly below. The arrangement of two lower network cable female connectors and two corresponding upper network cable female connectors enables the device to test two desktop computers in one test. Optionally, one lower network cable female connector corresponds to 8 probes, a total of 16 probes are provided on the lower circuit board, and 16 probe contact points are provided on the corresponding upper circuit board.

[0035] The working process of this embodiment is as follows: the lower test assembly is installed on the lower fixed plate, the probe protection seat and the fixed panel are installed on the lower fixed plate, the probe is located in the through hole of the probe protection seat in the non-working state, the upper test assembly is installed on the upper mounting plate, the two networked network cables are respectively inserted into the two lower network cable female heads, and one end of the other two network cables is inserted into the two Internet cable female heads, and the other ends are respectively inserted into different desktop computer hosts. The two pairs of Internet cable female heads and the lower network cable female heads correspond to each other left and right, up and down, and cannot be used crosswise. A manipulator is used to grab the upper mounting plate and place it on the probe protection seat. Due to the gravity of the upper mounting plate and the upper test assembly, the probe protection seat moves down, and the probe is exposed and contacts with the probe contact point to carry out testing. After the test is completed, the manipulator is used to remove the upper mounting plate. Since the elastic member is compressed, the elastic member drives the probe protection seat to move up and reset, thereby protecting the probe, and the device returns to the non-working state.

[0036] The advantages and positive effects of the present invention are as follows: the present invention provides a computer automatic electrical testing device, in which the probe is directly welded to a lower circuit board with a lower network cable female connector, and the network cable is directly connected to the lower network cable female connector, thereby greatly improving the network quality; a probe contact point for selectively contacting the probe is provided on the upper circuit board, and during testing, the network cable female connector is connected to a host computer of a desktop computer via a network cable, and the lower network cable female connector is directly connected to the network cable, and an upper mounting plate with an upper circuit board installed is placed above a probe protection seat by a manipulator to realize automatic connection of the network; this embodiment has the advantages of simple processing and low cost, and the network transmission speed reaches gigabit, thus meeting the testing requirements.

[0037] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
