[0048] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0049] like Figures 1-3 As shown, a high-speed cable testing device includes a fixed base plate 1 on which:

[0050] The carrier 2 is used to support the cable under test and can reciprocate along the X-axis and Y-axis;

[0051] The testing element 3 is used to connect and cooperate with the terminals 16 on the cable under test to test the cable. The testing element 3 is located on one side of the carrier 2 along the Y-axis. Each cable end has several terminals 16, and the terminals 16 are spaced apart along the X-axis and located on the terminal block 17. Figure 8 and Figure 9 As shown;

[0052] The floating test stand 4 includes a floating base 412, an X-axis floating block 401 floating on the floating base 412 along the X-axis direction, a Z-axis floating block 402 floating on the X-axis floating block 401 along the Z-axis direction, and a Y-axis floating block 403 floating on the Z-axis floating block 402 along the Y-axis direction. The test piece 3 is mounted on the Y-axis floating block 403.

[0053] During testing, the cable is placed on the carrier 2 and moved along the Y-axis to the testing component 3 for testing. After the first terminal 16 is tested, the carrier 2 is moved along the X-axis and the second and third terminals 16 are tested in sequence. No manual insertion testing is required. At the same time, when the testing component 3 is inserted and mated with the terminal 16, the testing component 3 can float in the X, Y and Z axis directions, which can avoid damage to the terminal 16 during the insertion process.

[0054] In some examples, such as Figures 4-7As shown, an X-axis guide rod 404 is fixed on the floating base 412, and an X-axis floating block 401 is sleeved on the outside of the X-axis guide rod 404 with an X-axis linear bearing 405 installed between them. An X-axis spring plunger 406 is provided between the floating base 412 and the X-axis floating block 401. The floating base 412 is roughly U-shaped and has a sliding cavity inside. The X-axis floating block 401 can slide along the X-axis guide rod 404 in the sliding cavity, and the X-axis spring plunger 406 can provide cushioning for the X-axis floating block 401.

[0055] In some examples, such as Figures 4-7 As shown, a Z-axis guide rod 407 is fixed on the X-axis floating block 401, and a Z-axis floating block 402 is sleeved on the outside of the Z-axis guide rod 407 with a Z-axis linear bearing 408 installed between them. A Z-axis spring plunger 409 is provided between the X-axis floating block 401 and the Z-axis floating block 402. The X-axis floating block 401 is roughly U-shaped and has a sliding cavity inside. The Z-axis floating block 402 can slide along the Z-axis guide rod 407 in the sliding cavity, and the Z-axis spring plunger 409 can provide buffering for the Z-axis floating block 402.

[0056] In some examples, such as Figures 4-7 As shown, a Y-axis guide rod 410 is fixed on the Z-axis floating block 402, and a Y-axis floating block 403 is sleeved on the Y-axis guide rod 410. An elastic element 411 is provided between the Z-axis floating block 402 and the Y-axis floating block 403. The elastic element 411 is sleeved on the Y-axis guide rod 410, with one end abutting against the Z-axis floating block 402 and the other end abutting against the Y-axis floating block 403. The Y-axis floating block 403 can slide along the Y-axis guide rod 410, and a limiting protrusion is formed at the end of the Y-axis guide rod 410 to limit the sliding stroke of the Y-axis floating block 403. The elastic element 411 can provide buffering for the Y-axis floating block 403.

[0057] In some examples, such as Figure 1 As shown, there are several carriers 2, test pieces 3 and floating test seats 4, and the three correspond one to one. The number can be, but is not limited to, one, two or three, etc., and the several carriers 2 and several floating test seats 4 are distributed at intervals along the X-axis direction. The several carriers 2 are supported by the platform 15.

[0058] In some examples, such as Figure 1As shown, the connecting plate 9 is equipped with an indicator arrow 10 and an indicator spring plunger 11. The fixed base plate 1 is marked with a test quantity scale 12 that cooperates with the indicator arrow 10 and an indicator groove 101 that cooperates with the spring plunger. The number of test quantity scales 12, indicator grooves 101 and the number of terminals 16 on each cable are all corresponding. Each indicator groove 101 extends along the X-axis and corresponds to the position of each test quantity scale 12. In this embodiment, there are seven terminals 16 on each cable, and the test quantity scale 12 is 1-7. When the indicator arrow 10 points to "1" in the test quantity scale 12, the first terminal 16 is detected. At this time, the indicator spring plunger 11 is located in the indicator groove 101 corresponding to "1" in the test quantity scale 12. The second and third terminals 16 can be detected in the same way. The cooperation between the indicator spring plunger 11 and the indicator groove 101 can improve the operator's operating feel, so that the terminal 16 and the detection piece 3 can be quickly aligned and plugged in, thereby improving the detection efficiency.

[0059] In some examples, such as Figure 3 As shown, an X-axis guide mechanism and a Y-axis guide mechanism are provided between the carrier 2 and the fixed base plate 1;

[0060] The X-axis guiding mechanism includes an X-axis guide rail 5 fixed on a fixed base plate 1 and an X-axis slider 6 that cooperates with the X-axis guide rail 5. The two work together to provide guidance in the X-axis direction of the carrier 2.

[0061] The Y-axis guiding mechanism includes a Y-axis slider 7 installed at the bottom of the carrier 2 and a Y-axis slide rail 8 that cooperates with the Y-axis slider 7. The Y-axis slide rail 8 and the X-axis slider 6 are fixed by a connecting plate 9. The two cooperate to provide guidance in the Y-axis direction of the carrier 2.

[0062] In some examples, such as Figure 1 As shown, the carrier 2 includes a positioning base plate 201 and positioning upright plates 202 fixed on both sides of the positioning base plate 201 along the X-axis direction. The positioning upright plates 202 and the positioning base plate 201 enclose a receiving cavity 203 for accommodating the cable terminal 16. The end of the positioning upright plate 202 facing away from the detection element 3 is bent to form a limiting part for limiting the terminal 16 in the Y-axis direction, which can avoid the detection failure caused by the terminal 16 being forced to detach from the carrier 2 during the insertion process of the terminal 16 and the detection element 3.

[0063] In some examples, such as Figure 5 and Figure 6 As shown, a limiting plate 13 is fixed between the Y-axis floating block 403 and the detection piece 3. The limiting plate 13 includes a plate body 1301 for abutting against the terminal 16 to limit the detection piece 3 in the Y-axis and a protrusion 1302 protruding from the plate body 1301 and cooperating with the receiving cavity 203 to limit the detection piece 3 in the Z-axis.

[0064] The cross-sectional area of ​​the plate 1301 is much larger than that of a single terminal 16. When the detection element 3 is inserted into the terminal 16, the insertion depth of the two can be limited by the plate 1301 to avoid damaging the terminal 16.

[0065] The positioning base plate 201 has a recess at one end near the detection element 3 to form a limiting groove 204 for the protrusion 1302 of the limiting plate 13 to be inserted. When the detection element 3 is inserted into the terminal 16, the protrusion 1302 is inserted into the limiting groove 204 to limit the detection element 3 in the Z-axis direction, so as to avoid the detection element 3 and the terminal 16 from deviating in the Z-axis direction, which would lead to detection failure.

[0066] In some examples, such as Figure 1 As shown, the fixed base plate 1 is fixed with a limiting block 14 for limiting the connecting plate 9 in the X-axis direction. There are two limiting blocks 14, which are located on both sides of the connecting plate 9 along its axial direction.

[0067] Working principle:

[0068] During testing, the cable is placed on the carrier 2 and moved along the Y-axis to the testing part 3 for testing. When the indicator arrow 10 points to "1" in the test quantity scale 12, it means that the first terminal 16 is being tested. At this time, the indicator spring plunger 11 is located in the indicator groove 101 corresponding to "1" in the test quantity scale 12. After the first terminal 16 is tested, the carrier 2 is moved along the X-axis to test the second and third terminals 16. The cooperation between the indicator spring plunger 11 and the indicator groove 101 can improve the operator's operating feel, so that the terminal 16 and the testing part 3 can be quickly aligned and plugged in, thereby improving the testing efficiency.

[0069] When the detection element 3 is inserted into the terminal 16, the limiting plate 13 first limits the detection element 3 in the Y-axis and Z-axis directions. At the same time, the X-axis floating block 401 can slide in the sliding cavity along the X-axis guide rod 404, and the X-axis spring plunger 406 can provide buffer for the X-axis floating block 401 so that the detection element 3 can float in the X-axis direction. The Z-axis floating block 402 can slide in the sliding cavity along the Z-axis guide rod 407, and the Z-axis spring plunger 409 can provide buffer for the Z-axis floating block 402 so that the detection element 3 can float in the Z-axis direction. The Y-axis floating block 403 can slide along the Y-axis guide rod 410, and the elastic element 411 can provide buffer for the Y-axis floating block 403 so that the detection element 3 can float in the Z-axis direction. This can avoid damage to the terminal 16 during the insertion process.

[0070] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
