[0033] In the description of this application, it should be noted that the terms "center", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] like Figures 1 to 4As shown in the figure, this application embodiment provides a testing device for testing chips to determine whether the chips can perform their functions. The testing device provided by this application embodiment can improve the installation accuracy and efficiency of boards such as resource boards and communication boards. Specifically, the testing device of this application embodiment includes a housing, in which a frame 110 for installing boards is installed; the frame 110 has multiple parallel and spaced board workstations, and the board workstations can be equipped with boards such as communication boards or resource boards according to actual needs; one side of the frame 110 has an installation port for board insertion, and the installation port is connected to each board workstation.

[0035] To achieve precise installation of the circuit boards, multiple pairs of guide rails 112 are symmetrically constructed on the inner walls of both sides of the frame 110. Each pair of guide rails 112 corresponds to a circuit board station. This arrangement facilitates accurate installation of the circuit boards into the frame 110 by leveraging the guiding effect of the guide rails 112, while also improving installation efficiency. To further enhance installation efficiency and accuracy, a chamfered inlet 114 is provided at one end of each guide rail 112 near the installation opening.

[0036] In order to improve the insertion and removal efficiency of the board, the chassis 110 is provided with multiple extraction ports 115. Each extraction port 115 is set to correspond one-to-one with each chamfered inlet 114. With this setting, the extraction aid on the board can be fixedly placed at the extraction port 115, and when the board needs to be removed, it provides support based on the extraction port 115 to improve the insertion and removal efficiency.

[0037] In one embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the frame 110 includes a pair of parallel and spaced side plates 116, a pair of parallel and spaced track plates 111, and a fixing plate 113. The two side plates 116 and the two track plates 111 are connected end to end to form an annular frame. The fixing plate 113 is fixedly connected to the same side end face of each side plate 116 and each track plate 111, so that one side of the annular frame is configured as an installation port for inserting circuit boards. That is, the same side end of each track plate 111 is fixedly connected to one side plate 116, and the other side end is fixedly connected to another side plate 116. The same side end face of each track plate 111 and each side plate 116 is perpendicularly connected to the same side of the fixing plate 113. With this arrangement, multiple circuit board stations for accommodating circuit boards can be formed in the space enclosed by the track plates 111, side plates 116, and fixing plate 113. In order to reduce the weight and cost of the testing device, the side plate 116, the track plate 111 and the fixing plate 113 are preferably made of aluminum alloy sheet. In order to improve the practical safety of the testing device, the frame 110 can be chemically nickel plated to form a nickel plating layer on the surface of the frame 110.

[0038] Each track plate 111 has multiple guide rails 112 symmetrically constructed on both sides facing each other. Each guide rail 112 is perpendicular to the fixed plate 113 along its length, and each chamfered inlet 114 is located at the end of the guide rail 112 away from the fixed plate 113. This arrangement facilitates the insertion and removal of the board and also effectively improves the installation accuracy of the board.

[0039] Understandably, the side plate 116 and the track plate 111 can be integrally formed, and the fixing plate 113 can be fixedly connected to the side plate 116 and the track plate 111 using bolts or other connecting parts. The multiple board stations set in the frame 110 include: a communication station 127 for inserting communication boards, and multiple resource stations for inserting resource boards. The communication station 127 has the same number of resource stations on both sides, so that the communication board set in the communication station 127 can be arranged side by side with the resource boards set in the multiple resource stations. A pair of back plates are centrally symmetrically provided on the fixing plate 113. Each back plate can be simultaneously inserted and mated with the communication board inserted in the middle of the frame. This arrangement eliminates the need for flying wire connections between the back plates and the communication boards, simplifies the structure, and has good practicality.

[0040] In one embodiment, to facilitate accurate insertion of the board, such as Figure 5 and Figure 7 As shown, a plurality of first guide holes 123 are provided on the surface of the fixing plate 113 facing the chamfered entrance 114. Each first guide hole 123 is provided in correspondence with each board station so that when the board is installed, the guide post provided at the board can be inserted and matched with the first guide hole 123, thereby improving the installation accuracy.

[0041] In one embodiment, such as Figure 7 As shown, in order to further improve the installation accuracy and stability of the board, the surface of the fixing plate 113 facing the chamfered entrance 114 is provided with a plurality of second guide holes 124, each of which corresponds to a first guide hole 123. The diameter of the second guide hole 124 is smaller than that of the first guide hole 123. At the same time, the board is also provided with guide posts corresponding to the first guide hole 123 and the second guide hole 124 respectively. This arrangement can facilitate the positioning and installation of the board, and also facilitate the identification of the board's position based on the difference in diameter between the first guide hole 123 and the second guide hole 124, so as to avoid incorrect insertion.

[0042] In one embodiment, the side plate 116 and the track plate 111 are fixedly connected by a plurality of first connectors, and the fixing plate 113 is fixedly connected to both the side plate 116 and the track plate 111 by a plurality of second connectors. It is understood that the first and second connectors can be screws, bolts, or other fasteners capable of threaded connection.

[0043] To avoid the first and second connectors protruding from the surface of the frame 110 and affecting assembly, such as Figure 6 As shown, the side plate 116 is provided with a plurality of first countersunk holes 117, and each first connector is correspondingly inserted into each first countersunk hole 117 to fix the side plate 116 to the track plate 111, with the end of the first connector away from the track plate 111 located inside the first countersunk hole 117. Additionally, as... Figure 8 As shown, the fixing plate 113 is provided with a plurality of second countersunk holes 125, and each second connector is correspondingly inserted into each second countersunk hole 125 so that the fixing plate 113 is fixedly installed on each side plate 116 and each track plate 111, and the end of the second connector away from the track plate 111 or the side plate 116 is located in the second countersunk hole 125.

[0044] In one embodiment, to facilitate the fixing of the circuit boards inserted at each board station, the surface of the track plate 111 facing away from the fixing plate 113 is provided with multiple locking holes 126. Each locking hole 126 corresponds to a guide rail 112. This arrangement facilitates the locking of the circuit boards onto the machine frame 110 using fasteners such as pins and screws. In addition, to prevent the circuit boards from stripping, anti-slip sleeves are fitted into each locking hole 126, providing a better fixing effect.

[0045] In one embodiment, in order to improve the heat dissipation effect inside the frame, each track plate 111 is provided with multiple heat dissipation vents 121, and each heat dissipation vent 121 is staggered with each guide track 112 to avoid interference.

[0046] In one embodiment, such as Figure 5 and Figure 7 As shown, the fixing plate 113 has multiple limiting slots 119 through it. Each board station is set with at least one limiting slot 119. This setting can facilitate the connection of the board to the external test component through the connecting wire, while also avoiding the situation of messy wiring.

[0047] In one embodiment, in order to achieve a fixed installation between the housing and its internal frame 110, such as Figure 1 As shown, each of the two opposite sides of the side plates 116 is equipped with a fixing seat 122. The side plates 116 are fixedly connected to the housing through the fixing seats 122. This arrangement allows the frame 110 to be fixed inside the housing, and also creates space between the housing and the frame 110 to facilitate the installation of electrical modules, air-cooling modules, etc.

[0048] In one embodiment, such as Figure 2 and Figure 6 As shown, a clamping seat 120 is fixedly installed on each of the two opposite sides of the side plate 116. The clamping seat 120 has multiple clamping holes 118. At the same time, the housing has through holes corresponding to the positions of each clamping hole 118. With this arrangement, the robotic arm of the external device can sequentially extend into the through holes and the corresponding clamping holes 118 and be fixed on the clamping seat 120. Then, the clamping arm can clamp the clamping seat 120 to achieve the goal of clamping the frame 110, so as to facilitate the handling or adjustment of the position of the testing device.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
