[0013] In one embodiment of this utility model, the rectangular groove is disposed between two slide rails; the upper end of the T-shaped plate is provided with a groove in the area corresponding to the rectangular groove.

[0014] In one embodiment of the present invention, the second connecting terminal is configured as an L-shaped structure, with the lower end of the L-shaped second connecting terminal passing through the groove and bypassing the lower end of the T-shaped plate to be electrically connected to the second connecting seat.

[0015] In one embodiment of the present invention, the lower end of the base near the first connecting seat is provided with a first positioning post, and the product under test is provided with a second positioning post on the side of the contact terminal.

[0030] Please see Figure 1 , Figure 5 This utility model provides a high current connection mechanism, including two output terminals 3 connected from the test module and a product under test 2. The product under test 2 is provided with two contact terminals 4. The upper end of the contact terminal 4 is provided with a bent portion 41, and the bent portions 41 of the two contact terminals 4 are arranged opposite to each other.

[0031] Please see Figures 2-4 The high-current connection mechanism further includes a base 5, a first connecting terminal 6, a first connecting seat 7, a second connecting terminal 8, and a second connecting seat 9. The base 5 is provided with a rectangular groove 51. The first connecting terminal 6 passes through the base 5. The upper end of the first connecting terminal 6 is connected to one of the output terminals 3. The first connecting seat 7 is located at the lower end of the base 5 and is electrically connected to the first connecting terminal 6. The second connecting terminal 8 is movably fitted in the rectangular groove 51, and the upper end of the second connecting terminal 8 is connected to the other output terminal 3. The second connecting seat 9 is electrically connected to the lower end of the second connecting terminal 8. The first connecting seat 7 and the second connecting seat 9 are provided with a plurality of parallel spring contacts 10 on the same side. Referring to the attached drawings, the same side of the first connecting seat 7 and the second connecting seat 9 is the side closer to the product under test 2. The first connecting seat 7 and the second connecting seat 9 are electrically connected to the two contact terminals 4 through a plurality of spring contacts 10. This utility model, by setting two connection terminals and two connection seats, and the several parallel spring contacts 10 set on the connection seats, can form a large-area contact between the output terminal 3 and the contact terminal 4, thereby improving the stability of the connection between the test module 1 and the product under test 2; and the large-area connection formed by several spring contacts 10 can effectively improve the current carrying capacity and meet the use requirements of high current for specific interfaces during electronic product testing.

[0032] The lower end of the base 5 is provided with two slide rails 11, and a slider 12 is slidably engaged on each slide rail 11. A T-shaped plate 16 is connected to the lower end of the two sliders 12, and the second connecting seat 9 is mounted on the T-shaped plate 16. The rectangular groove 51 is provided between the two slide rails 11, and the area corresponding to the rectangular groove 51 on the upper end of the T-shaped plate 16 is provided with a groove 161. The second connecting terminal 8 is set with an L-shaped structure. The lower end of the L-shaped second connecting terminal 8 passes through the groove 161 and bypasses the lower end of the T-shaped plate to be electrically connected to the second connecting seat 9. This invention features a second connecting seat 9 mounted on a T-shaped plate 16. The T-shaped plate 16, via a sliding rail 11 and a slider 12, can move closer to or further away from the first connecting seat 7. When the two contact terminals 4 of the product under test are inserted into the first connecting seat 7, several spring contacts 10 on the first connecting seat 7 reliably contact one of the contact terminals 4. At this time, the T-shaped plate 16 is driven manually or by a cylinder to move along the sliding rail 11 towards the first connecting seat 7 until it presses against the side end of the other contact terminal 4. The bent portion 41 of the other contact terminal can then press against the upper end of the second connecting seat 9, preventing the contact terminal 4 from detaching from the first connecting seat 7 and the second connecting seat 9. The several spring contacts 10 on the second connecting seat 9 reliably contact the other contact terminal 4, improving the testing effect of electronic products. After the test is completed, the T-shaped plate 16 is driven manually or by a cylinder to move the second connecting seat 9 away from the first connecting seat 7, allowing the contact terminal 4 to be removed.

The first positioning post 13 and the second positioning post 14 abut against each other after the test module 1 and the product under test 2 are connected in place, so as to avoid the electrical connection effect being affected by improper insertion and the terminal being damaged by excessive insertion. The lower end of the base 5 away from the second connecting seat 9 is provided with a positioning block 15, and a locking bolt 1 is fitted on the positioning block 15. The T-shaped plate 16 is provided with a slot 162 on the plate body away from the second connecting seat 9. After the test module 1 and the product under test 2 are electrically connected, the locking bolt 1 can be detachably passed through the slot 162 to lock the T-shaped plate 16 on the positioning block 15, so as to ensure the reliability of the connection between the test module 1 and the product under test 2 during the test.

[0034] In summary, this invention, through the combination of connecting terminals and connecting seats, allows for a large-area contact between the output terminal 3 and the contact terminal 4 by several parallelly arranged spring contacts 10 on the connecting seat, thereby improving the current-carrying capacity and the stability of the electrical connection. The slide rail 11, slider 12, and T-shaped plate 16 enable the second connecting seat 9 to quickly approach and separate from the first connecting seat 7, facilitating rapid insertion and removal of the product under test 2 from the test module 1. Therefore, this invention effectively overcomes the various shortcomings of the prior art and possesses high industrial applicability.
