[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0041] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0043] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] In this embodiment, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0045] like Figure 1-Figure 6As shown, the present embodiment provides a plug-in card type single board test device, which is used to detect a chassis to be tested 10, wherein a plurality of boards 101 are arranged in the chassis to be tested along a first direction, and a plug-in card type single board test device comprises a plurality of drive devices 1 and a plurality of single board test modules 2 arranged at intervals along the first direction, wherein the drive device 1 is provided with a first mounting seat 11; the single board test module 2 can be selectively installed on the first mounting seat 11, and the single board test module 2 is provided with a probe 21, and the drive device 1 can drive the single board test module 2 to move along a second direction (i.e., a direction close to the chassis to be tested 10) so that the probe 21 is plugged into the plug-in card type single board test device. The plurality of single board test modules 2 are independent of each other, and the arrangement order of the plurality of single board test modules 2 can be adaptively adjusted according to actual test requirements, therefore, different chassis to be tested 10 only need one plug-in card type single board test device for testing, thereby reducing production costs. The driving device 1 drives the single board test module 2 to move along the second direction so that the probe 21 is plugged into the socket, thereby realizing that the single board test module 2 is automatically plugged into the socket of the board 101, reducing labor costs and improving test efficiency.

[0046] Since the test device in the prior art is an integrated structure, when the position of individual boards is deviated, it is easy to cause poor contact between the probe and the board. Figure 2-Figure 5 As shown, the single-board test module 2 also includes a shell 22 and a floating component 23, the floating component 23 includes a floating plate 231 and a second mounting seat 24, the second mounting seat 24 is mounted on the floating plate 231, the probe 21 is mounted on the second mounting seat 24, and the floating plate 231 is floatingly mounted in the shell 22; two first mounting holes are provided on the floating plate 231, and conical push rods 25 are installed in the first mounting holes, the two conical push rods 25 are located at both ends of the probe 21 and the conical push rods 25 protrude from the probe 21 at one end close to the board 101, during the insertion of the probe 21, the conical push rod 25 can preferentially contact the chassis 10 to be tested, and a positioning hole corresponding to the conical push rod 25 is provided on the board 101, and the conical push rod 25 can be inserted into the positioning hole. When the driving device 1 drives the single-board test module 2 to be plugged into the socket of the board 101, the two conical push rods 25 preferentially extend into the two positioning holes. Since the conical push rods 25 are installed on the floating plate 231, the conical portion of the conical push rods 25 can be guided by the positioning holes, and the floating plate 231 can adaptively move following the conical push rods 25 to align the probe 21 with the socket, thereby preventing poor contact between the probe 21 and the socket.

[0047] More preferably, if Figure 3 and Figure 4As shown, a spring 252 is provided between the conical push rod 25 and the first mounting hole, and the conical push rod 25 is slidably installed in the first mounting hole. When the tip of the conical push rod 25 abuts against the bottom of the positioning hole, the conical push rod 25 overcomes the elastic force of the spring 252 and retracts into the first mounting hole to prevent the conical push rod 25 from interfering with the bottom of the positioning hole.

[0048] Preferably, a photoelectric sensor 26 is provided on the inner wall of at least one first mounting hole, and the conical push rod 25 is provided with an annular groove 251. When the probe 21 is inserted into the socket, the light beam of the photoelectric sensor 26 passes through the annular groove 251; when the probe 21 is not inserted into the socket, the conical push rod 25 blocks the light beam of the photoelectric sensor 26. The photoelectric sensor 26 can detect whether the conical push rod 25 is retracted into place, and then detect whether the probe 21 of the single-board test module 2 is well connected with the socket of the board 101.

[0049] Furthermore, if Figure 5 As shown, guide portions 2311 are provided at both ends of the floating plate 231, and the shell 22 includes a bottom shell 221 and a cover plate 222. A guide groove 2211 corresponding to the guide portion 2311 is provided on the bottom shell 221, and the guide portion 2311 is floatingly installed in the guide groove 2211. The cover plate 222 presses the floating plate 231 to the bottom shell 221, thereby realizing the floating installation of the floating plate 231 in the shell 22.

[0050] In this embodiment, a first elastic member 232 is provided between the end of the guide portion 2311 and the guide groove 2211. Through the first elastic member 232 at the upper and lower ends of the floating plate 231, it is achieved that the floating plate 231 can float relative to the shell 22 along the third direction. The two side walls of the guide portion 2311 along the first direction are provided with second mounting holes, and a ball plunger 233 is installed in the second mounting hole. When the cover plate 222 is installed on the bottom shell 221, a ball plunger 233 is provided between the floating plate 231 and the guide groove 2211 and between the floating plate 231 and the cover plate 222, so that the floating plate 231 can float relative to the shell 22 along the first direction. In this embodiment, the floating plate 231 can float relative to the shell 22 along the first direction and the third direction, so that the floating plate 231 can be adaptively adjusted with the conical push rod 25, thereby ensuring that the probe 21 of the single-board test module 2 is well docked with the socket of the board 101.

[0051] In this embodiment, the shell 22 is made of aluminum alloy, which ensures strength and precision while reducing the weight of the single board test module 2.

[0052] Preferably, the two side walls of the guide portion 2311 along the second direction are provided with third mounting holes, and a steel ball 234 is installed in the third mounting hole. A slide plate 235 is installed in the guide groove 2211, and the steel ball 234 abuts against the slide plate 235. The slide plate 235 is embedded in the guide groove 2211. Since the material of the housing 22 is relatively soft, when the floating plate 231 floats, the steel ball 234 abuts against the slide plate 235. The slide plate 235 is made of steel with high hardness, which prevents the steel ball 234 from damaging the housing 22. At the same time, the steel ball 234 is provided to facilitate the movement of the floating plate 231 and improve the movement accuracy of the floating plate 231.

[0053] Furthermore, if Figure 5 As shown, the single-board test module 2 also includes a docking baseboard interface 28. A fourth mounting hole is provided at the bottom of the shell 22. The docking baseboard interface 28 is installed in the fourth mounting hole. The docking baseboard interface 28 is electrically connected to the probe 21 through a wiring harness to adapt to changes in product size.

[0054] Preferably, a label 29 is provided on the top of the housing 22. The label 29 may be a barcode, and the type of the single board test module 2 may be identified by the label 29, so as to facilitate database management of the single board test module 2. When the single board test module 2 is put into storage, its position may be recorded according to the label 29, and when used, automatic management of the test equipment may be realized.

[0055] In this embodiment, a handle 27 is further provided on the housing 22 , and the handle 27 is used for manually taking and placing the single board test module 2 , thereby improving convenience.

[0056] More specifically, Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the plug-in single-board test device also includes a third mounting seat 3, and the chassis to be tested 10 is installed on the third mounting seat 3; the driving device 1 also includes a bottom plate 12, a fourth mounting seat 13, a driving member 14 and a second slider 15, the first mounting seat 11 is slidably connected to the bottom plate 12, the fourth mounting seat 13 is fixed to the bottom plate 12, the driving member 14 is installed on the fourth mounting seat 13, the output end of the driving member 14 is connected to the first mounting seat 11, and the first mounting seat 11 is provided with a first slide groove 111, and the single-board test module 2 is away from the side of the chassis to be tested 10 along the third Two first sliders 201 are arranged at intervals in the direction, and the first slider 201 is slidably connected to the first slide groove 111, so that the single board test module 2 is fixed on the first mounting seat 11; the third mounting seat 3 is provided with a second slide groove 31, and a bushing 202 is installed at the bottom of the single board test module 2. A latch 151 is arranged on the second slider 15, and the latch 151 is plugged into the bushing 202, so that the second slider 15 is connected to the bottom of the single board test module 2, and the second slider 15 is slidably connected to the second slide groove 31, thereby improving the moving accuracy of the single board test module 2. In this embodiment, the single board test module 2 is slidably installed on the first mounting seat 11 through the two first sliders 201, and the second slider 15 improves the stability of the installation of the single board test module 2, and the operation is simple and the installation efficiency is high. When the driving member 14 drives the first mounting seat 11 to move, the first mounting seat 11 drives the single board test module 2 to move along the second direction, and the single board test module 2 is guided by the second slider 15, thereby improving the moving accuracy of the single board test module 2. In this embodiment, the driving member 14 is a cylinder.

[0057] Preferably, the driving device 1 further comprises a locking member 16. When the first slider 201 slides to a preset position, the locking member 16 is mounted on the first mounting seat 11, and the locking member 16 blocks the top wall of the first slider 201. After the first slider 201 of the single board test module 2 is slidably connected to the first slide groove 111, the single board test module 2 is assembled, and then the locking member 16 is installed. The locking member 16 blocks the top wall of the first slider 201 to prevent the single board test module 2 from shaking relative to the first mounting seat 11 or even detaching from the first slide groove 111, thereby improving the installation stability of the single board test module 2.
