[0040] like Figures 1 to 20 As shown, the present invention provides a circuit pin plugging and unplugging test device, comprising a base 1 and a moving mechanism 2. The moving mechanism 2 is arranged on the base 1, and the moving mechanism 2 can move closer to or away from each other to clamp the connection terminal 3.

[0041] It can be understood that the moving mechanism 2 can be moved closer to or farther from each other, thereby clamping the connection terminals 3 of different lengths and adapting to the connection terminals 3 of different models.

[0042] Preferably, the base 1 is provided with a symmetrically arranged fixing block 4, which can be installed on the base 1, or the base 1 and the fixing block 4 can be kept as an integral structure. A holding area 5 is formed between the fixing blocks 4, and the size of the holding area 5 can clamp the connection terminals 3 of different lengths. The fixing block 4 is provided with a first threaded hole 6 and a symmetrically arranged sliding hole 7, the sliding hole 7 is a through hole, and the sliding rod 9 can slide in the sliding hole 7. When the holding area 5 is the smallest, the first spring 8 at this time pushes the sliding rod 9 to be in a natural state, and a part of the sliding rod 9 is in the sliding hole 7.

[0043] A fixing plate 10 and a positioning plate 11 are also provided in the middle of the base 1. The fixing plate 10 and the positioning plate 11 are installed opposite to each other, and the middle is a holding area 5.

A test plate 16 is provided in the middle of the positioning plate 11.

[0044] Preferably, the positioning plate 11 is provided with a second mounting groove 17 and a second opening 18, the second mounting groove 17 is connected with the second opening 18, and the test board 16 is provided with a symmetrically arranged positioning end 19 and a test end 20, the positioning end 19 is arranged in the second mounting groove 17, and the test end 20 is arranged in the second opening 18. By using connection terminals 3 of different lengths, test boards 16 corresponding to different models can be installed, so that the pins on the connection terminals 3 can be plugged and unplugged correspondingly with the sockets on the test board 16, and the pins on the connection terminals 3 can be tested, and life tests can be performed on them.

[0045] Preferably, the moving mechanism 2 is mounted on the fixed block 4, and a moving seat 21 and a holding assembly 22 are provided in the moving mechanism 2, and the holding assembly 22 is arranged on the moving seat 21. The moving seat 21 is composed of a first plate body 23 and a second plate body 24, and the first plate body 23 and the second plate body 24 are arranged vertically. The first plate body 23 is placed on the fixed block 4, and a strip hole 25 is provided on the first plate body 23. The first plate body 23 is connected to the first threaded hole 6 through the strip hole 25 by a fastener 26. A first threaded portion 27 is provided on the fastener 26, and the first threaded portion 27 is kept corresponding to the first threaded hole 6.

[0046] It is understandable that, during installation, the hexagonal portion 28 on the fastener 26 does not contact the first plate 23 , so that the fastener 26 can limit the position of the movable seat 21 but does not limit the movement of the movable seat 21 .

[0047] The second plate body 24 is provided with a symmetrically arranged sliding rod 9 which is placed in the sliding hole 7 . The sliding rod 9 is sleeved with a first spring 8 . One end of the first spring 8 contacts the second plate body 24 , and the other end contacts the fixed block 4 .

[0048] It can be understood that the first spring 8 can be used to push the movable seat 21 to keep the movable seat 21 cooperating with the retaining assembly 22 to clamp the connecting terminals 3 of different lengths.

[0049] Preferably, the holding assembly 22 is provided with a holding seat 29, a positioning member 30, a holding member 31, a fixing member 32 and a symmetrically arranged holding block 33. The holding seat 29 is arranged on the first plate 23 through the positioning member 30 and the holding member 31. The first plate 23 is provided with a second threaded hole 34 that cooperates with the positioning member 30 and a third threaded hole 35 that cooperates with the fixing member 32. The fixing member 32 installs the holding member 31 on the first plate 23. The holding seat 29 pushes the holding member 31 to be deformed by force and installed between the holding member 31 and the positioning member 30. The positioning member 30 is provided with a second threaded portion 84 that cooperates with the second threaded hole 34.

[0050] It is worth mentioning that the fixing member 32 is composed of a third threaded portion 36 , a tightening portion 37 and a columnar portion 38 . The third threaded portion 36 cooperates with the third threaded hole 35 , and the columnar portion 38 is arranged in the middle of the retaining member 31 .

[0051] Preferably, the retaining seat 29 is composed of a transverse plate 39 and a vertical plate 40, the transverse plate 39 and the vertical plate 40 are vertically arranged, and the transverse plate 39 is arranged on the first plate body 23. The transverse plate 39 is provided with a notch for accommodating the positioning member 30, and the vertical plate 40 is provided with a first mounting groove 41 and a first opening 42, and the first mounting groove 41 is connected to the first opening 42. The retaining block 33 is arranged in the first mounting groove 41, and the retaining blocks 33 are connected to each other through an elastic member 43, and the retaining blocks 33 are separated by force, and the retaining elastic member 43 is stretched by force.

[0052] Preferably, the retaining member 31 is composed of a first vertical section 44, a first transverse section 45, a spiral section 46, a deformation section 47, a second vertical section 48, a second transverse section 49, a third vertical section 50, a third transverse section 51, a fourth transverse section 52, a guide section 53, an extension section 54 and an inclined section 55. The guide section 53 is provided with arc sections 56 at both ends, and the guide section 53 is connected to the fourth transverse section 52 and the extension section 54 through the arc sections 56, respectively, the third transverse section 51 and the fourth transverse section 52 are at the same horizontal height, the spiral section 46 is provided with a receiving hole 57 for receiving the column part 38 in the middle, and the movable seat 21 is provided with a vertical groove 58 matched with the first vertical section 44.

[0053] It can be understood that the second transverse section 49 , the third transverse section 51 , the extension section 54 and the inclined section 55 can expand the pressure application area of ​​the elastic member 43 , which is beneficial to the pressure application on the retaining seat 29 .

[0054] It is worth mentioning that since the guide section 53 and the third and fourth transverse sections 51 and 52 are not on the same horizontal plane, the retaining seat 29 can be placed at the lower end of the retaining member 31 in cooperation with the first guide surface 59, and the retaining member 31 applies pressure to the retaining seat 29.

[0055] The second vertical section 48 and the third vertical section 50 are in contact with the side of the movable seat 21 , and the retaining seat 29 is pushed toward the positioning member 30 by the elastic force of the deformation section 47 , so that the positioning member 30 is placed in the slot 60 , and the position of the retaining seat 29 is limited by the slot 60 .

[0056] An active gap 61 is formed between the spiral section 46 and the transverse plate 39, and the length of the notch 60 is smaller than the width of the active gap 61. When the driving member 13 pushes the push rod 15, the retaining seat 29 is pushed by the push rod 15 at this time, and the moving distance is H1, and the length of H1 is smaller than the distance of the notch 60, which prevents the positioning member 30 from being separated from the notch 60 after the retaining seat 29 is pushed, causing the retaining seat 29 to shift in position, and also prevents the deformation section 47 from being deformed excessively.

[0057] The transverse plate 39 is provided with a first guide surface 59 which is inclined, and the transverse plate 39 is also provided with second guide surfaces 83 which are arranged on both sides of the first guide surface 59, and the second guide surfaces 83 are inclined. The first guide surface 59 and the second guide surface 83 are used to guide the movement of the retaining seat 29 so that it reaches the lower end of the second transverse section 49 and the third transverse section 51, and reaches the limit position between the positioning member 30 and the elastic member 43.

[0058] A movable hole 62 is provided on one side of the symmetrical holding block 33 away from the middle, a second spring 63 is provided in the movable hole 62, a fourth threaded hole 64 is provided on the vertical plate 40, a bolt 65 is provided in the fourth threaded hole 64, a fourth threaded portion 66 matching the fourth threaded hole 64 is provided on the bolt 65, and the fourth threaded portion 66 passes through the second spring 63 and is placed in the movable hole 62. The bolt 65 can limit the holding block 33 from being disengaged from the first mounting groove 41, and can also limit the position of the second spring 63.

[0059] A protruding block 67 is provided on one side of the symmetrical retaining block 33 near the middle, a first inclined surface 68 is provided on the protruding block 67, a second inclined surface 69 adjacent to the first inclined surface 68 is provided on the retaining block 33, a clamping surface 70 is formed on one side of the symmetrical retaining block 33 near the middle, and an open gap 71 is formed between the clamping surfaces 70.

[0060] Preferably, the elastic member 43 is composed of a first connecting segment 72 and a symmetrically arranged second connecting segment 73, a third connecting segment 74 and a fourth connecting segment 75, wherein the first connecting segment 72 is arranged perpendicularly to the second connecting segment 73, and the second connecting segment 73 is arranged perpendicularly to the third connecting segment 74. The first connecting segment 72 is arranged parallel to the third connecting segment 74, the second connecting segment 73 is arranged parallel to the fourth connecting segment 75, and a stop block 76 is provided on the fourth connecting segment 75.

[0061] It is understandable that the elastic member 43 can cooperate with the second spring 63 to clamp the connecting terminal 3. When the connecting terminal 3 is inserted from the second inclined surface 69, the symmetrically arranged retaining block 33 can be pushed away, so that the second spring 63 is compressed and the elastic member 43 is stretched.

[0062] Preferably, the retaining block 33 is provided with an annular groove 77, and the elastic member 43 is arranged in the annular groove 77. Symmetrically arranged blocking blocks 78 are provided in the annular groove 77, a passing area 79 is formed between the blocking blocks 78, and a limiting area 80 for limiting the fourth connecting section 75 is formed between the blocking blocks 78 and the inner wall of the annular groove 77. A limiting groove 81 is also provided in the annular groove 77 to cooperate with the limiting block 76, and a limiting tooth 82 is provided in the limiting groove 81.

[0063] It is worth mentioning that the position of the fourth connecting section 75 can be limited by the blocking block 78 to prevent the limiting block 76 from being separated from the limiting groove 81 .

[0064] The limiting teeth 82 can apply pressure to the limiting block 76 , so that a tooth groove 85 is formed on the limiting block 76 , thereby preventing the limiting block 76 from being separated from the limiting groove 81 .

[0065] It should be noted that when testing the pins on the connection terminals 3, it is necessary to first install the test board 16 that matches the connection terminals 3 to be tested, and then install the connection terminals 3 on the retaining assembly 22. The retaining assembly 22 can be directly placed on the fixed block 4, or the connection terminals 3 can be placed on the retaining assembly 22 first, and then the retaining assembly 22 and the connection terminals 3 to be tested are placed on the fixed block 4 together. After the installation is completed, the driving member 13 can be started to push the retaining seat 29 in the retaining assembly 22. The elastic force of the deformation segment 47 is greater than the friction force of the pin inserted into the jack. After the driving member 13 pushes the pin to be inserted, the pin can be taken out of the jack under the elastic force of the deformation segment 47, which is convenient for the driving member 13 to push and insert again.

[0066] It is worth mentioning that Fig.19 As shown in FIG. 3 , the connection terminal 3 in the present application is provided with a clamping plate 86 and a connector 87. The middle of the connector 87 is hollowed out to form a docking hole 88. A pin 89 is provided in the docking hole 88. An anti-mute surface 90 is provided in the docking hole 88. Fig. 20 As shown, the test board 16 in the present application is provided with a plug hole 91 corresponding to the plug pin 89 on the test end 20 of the test board 16, and a contact surface 92 matched with the foolproof surface 90 is provided on the test end 20. When installing the connection terminal 3, the clamping plate 86 on the connection terminal 3 is placed in the open gap 71 between the symmetrically arranged retaining blocks 33 to achieve clamping of the connection terminal 3.

[0067] Before the test, the corresponding test board 16 and the connection terminal 3 need to be installed so that the pins 89 on the connection terminal 3 can be correspondingly inserted into the sockets 91 to implement the plug-in and pull-out test of the pins 89 .

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
