[0037] Reference Figures 1 to 3As shown, the present embodiment provides a connection device for circuit board detection, comprising a mounting plate 1 and an adjustment mechanism; the adjustment mechanism comprises: a fixing stud 4, one end of which is arranged on the mounting plate 1; a support arm 2, a connecting groove 20 is arranged on the support arm 2, the support arm 2 is rotatably sleeved on the fixing stud 4 through the connecting groove 20, and the fixing stud 4 can slide along the connecting groove 20; an adjusting nut 40, the adjusting nut 40 is threadedly engaged with the fixing stud 4; an abutment assembly, the abutment assembly is located between the support arm 2 and the mounting plate 1 to support the support arm 2; at least two probes 3, the probes 3 are mounted on the support arm 2.
[0038] The mounting plate 1 may be in a plate-like structure, has a certain degree of support, and can be stably placed on a desktop or on the ground.
[0039] The fixing stud 4 is a columnar structure with a section of thread thereon. The fixing stud 4 has a certain degree along its axial direction. In this embodiment, the lower end of the fixing stud 4 is connected to the mounting plate 1 and is preferably arranged perpendicular to the mounting plate 1 to facilitate operation and adjustment.
[0040] The support arm 2 is rotatably mounted on the fixed stud 4 through the connecting groove 20. It can be imagined that the support arm 2 can rotate relative to the fixed stud 4. In addition, the size of the rotation range depends on the length of the support arm 2. Therefore, when the support arm 2 has a certain length, the rotation range can be enlarged to a certain extent.
[0041] Therefore, the support arm 2 can have a certain length, and the connecting groove 20 formed thereon also has a certain length. The structure of the connecting groove 20 can refer to the mechanism of the narrow slot, so that the support arm 2 can be rotated through the connecting groove 20 and can also move along the length direction of the connecting groove 20, that is, its own length direction. Of course, in this process, the movement along the length direction of the connecting groove 20 and the rotation relative to the fixing stud 4 can also occur simultaneously.
[0042] The adjusting nut 40 and the abutment assembly are used to limit the movement of the support arm 2, and can also be understood as being used to adjust the movement of the support arm 2 relative to the fixing stud 4. The abutment assembly is located between the mounting plate 1 and the support arm 2, and applies an upward force to the bottom of the support arm 2. The adjusting nut 40 is located on the side of the support arm 2 facing away from the mounting plate 1, and the adjusting nut 40 and the abutment assembly are located on both sides of the support arm 2 on the axial direction of the fixing stud 4 to limit the support arm 2.
[0043] It can be imagined that when the adjusting nut 40 moves close to the support arm 2, the support arm 2 will move axially toward the mounting plate 1 along the fixing stud 4 under the action of the adjusting nut 40, that is, move downward. It is also conceivable that the supporting effect of the abutment assembly on the support arm 2 is adaptive, not fixed, and can certainly be considered adjustable. Therefore, in addition to the above-mentioned movement of being able to rotate the fixing stud 4 and move along its own direction, the support arm 2 can also move relative to the fixing stud 4 along the axial direction of the fixing stud 4.
[0044] It is not meaningless that the support arm 2 can move in various states relative to the fixed stud 4, that is, a probe 3 is installed on the support arm 2, one end of the probe 3 is used to connect the wire, and the other end is used to contact the circuit board or some integrated circuit component contacts; in actual situations, at least two probes 3 installed on the support arm 2 can be set, and there is a certain interval to meet the distance between different contacts.
[0045] The probe 3 can move in the horizontal plane under the action of the adjustment mechanism, that is, when the circuit board is horizontally arranged on the mounting plate 1, the movement of the probe 3 in the horizontal plane can cover the position of any contact on the circuit board. In addition, the entire support arm 2 can also move in the up and down directions to abut against the contact. More importantly, the wire connecting the test instrument or the computer can be connected to the non-detection end of the probe 3, and the detection end of the probe 3 can be contact-connected with the contact on the circuit board, avoiding the problem of directly soldering the wire to the circuit board in the traditional way to damage the circuit board or even scrap it.
[0046] In some other embodiments, the abutment assembly includes a spring 42 ; the spring 42 is sleeved on the fixing stud 4 .
[0047] Specifically, the spring 42 is sleeved on the fixing stud 4, the bottom end abuts against the top side of the mounting plate 1, and the top end abuts against the bottom of the support arm 2. Under the action of the adjusting nut 40 and the spring 42, the support arm 2 can be limited at a certain height relative to the mounting plate 1, thereby adjusting the distance between the detection end of the probe 3 and the contact point.
[0048] Under the effect of the adaptive elastic force of the spring 42 , it is very convenient to adjust the support arm 2 in the up and down directions, that is, the support arm 2 can be adjusted by simply rotating the adjusting nut 40 .
[0049] In some other embodiments, the abutment assembly includes a support nut; the support nut is screwed onto the fixing stud 4.
[0050] Specifically, the support nut is also screwed on the fixing stud 4. When the support arm 2 needs to be adjusted upward, the support nut and the adjusting nut 40 are adjusted upward at the same time. When the required height is reached, both are adjusted toward the support arm 2 to lock the support arm 2. When the support arm 2 needs to be adjusted downward, only the support nut needs to be adjusted downward. When the required height is reached, the fixing nut 43 is adjusted downward to lock the support arm 2. Under the action of the support nut, the position of the probe 3 after adjustment is more stable and less likely to change.
[0051] In some other embodiments, a gasket 41 is provided between the adjusting nut 40 and the support arm 2 and / or between the abutting assembly and the support arm 2 , and the gasket 41 is sleeved on the fixing stud 4 .
[0052] It can be imagined that since the support arm 2 can rotate in the horizontal plane under the action of the connecting groove 20, in order to ensure that the adjusting nut 40 and the abutment assembly have sufficient limiting performance on the support arm 2, gaskets 41 are arranged between the adjusting nut 40 and the support arm 2 and between the abutment assembly and the support arm 2 to ensure the limiting effect of the adjusting nut 40 and the abutment assembly on the support arm 2, and at the same time, it can also reduce the wear among the adjusting nut 40, the abutment assembly and the support arm 2, thereby increasing their service life.
[0053] In addition, under the action of the gasket 41, the adjusting nut 40 and the abutment assembly can avoid direct contact with the connecting groove 20, thereby reducing the probability of the adjusting nut 40 or the abutment assembly abutting into the inside of the connecting groove 20 due to unexpected size problems.
[0054] Of course, according to actual conditions, the gasket 41 may also be only provided between the adjusting nut 40 and the support arm 2 or between the abutting assembly and the support arm 2 .
[0055] In some other embodiments, at least two spaced-apart mounting holes 21 are provided on the support arm 2 , and the axial direction of the mounting holes 21 intersects with the rotation plane of the support arm 2 ; the probes 3 are correspondingly disposed in the mounting holes 21 .
[0056] The probe 3 is a needle-like structure, so a mounting structure such as a hole can be set to install the probe 3, that is, a mounting hole 21 is set on the support arm 2. In a preferred embodiment, the axial direction of the mounting hole 21 is the same as the axial direction of the fixing stud 4, so as to most efficiently drive the probe 3 to move in the up and down directions. However, in some conceivable embodiments, as long as the axial direction of the mounting hole 21 intersects with the rotation plane of the support arm 2, the detection end of the probe 3 can contact the contact during the downward process.
[0057] In addition, a number of mounting holes 21 may be arranged at intervals, but the probe 3 does not need to be installed in every mounting hole 21 . Instead, two mounting holes 21 with a contact pitch that meets the requirements are selected for installing the probe 3 to meet the contact adaptability of the probe 3 .
[0058] In some other embodiments, the support arm 2 is provided with an abutment hole 22, which is connected to the mounting hole 21; an abutment rod 5 is rotated in the abutment hole 22, one end of the abutment rod 5 is located outside the abutment hole 22, and the other end is located inside the abutment hole 22 to abut the probe 3.
[0059] Since the probe 3 may need to be adjusted according to actual conditions and it also needs to be fixed to the support arm 2, an abutment hole 22 connected to the mounting hole 21 is provided on the support arm 2 corresponding to the mounting hole 21, and an abutment rod 5 is rotated in the abutment hole 22. When the abutment rod 5 is rotated toward the inside of the abutment hole 22, the abutment rod 5 will abut against the probe 3 to fix the probe 3; when the abutment rod 5 is rotated toward the outside of the abutment hole 22, the abutment rod 5 will be separated from the probe 3 to release the fixation of the probe 3.
[0060] In some other embodiments, a rotating knob 50 is provided at one end of the abutment rod 5 located outside the abutment hole 22; specifically, in order to facilitate the rotation of the abutment rod 5, a rotating knob 50 is provided on one end of the abutment rod 5 located outside the abutment hole 22 to facilitate the operator to rotate.
[0061] In some other embodiments, the fixing stud 4 is a bolt; the head of the fixing stud 4 is sunk on the side of the mounting plate 1 facing away from the support arm 2, and a fixing nut 43 is provided on the side of the mounting plate 1 facing away from the head of the fixing stud 4, and the fixing nut 43 abuts against the side of the mounting plate 1 facing the adjusting nut 40.
[0062] Specifically, the fixing stud 4 can be a bolt; a countersunk hole is provided on the bottom side of the mounting plate 1, and the fixing stud 4 passes through the countersunk hole from bottom to top, and its head is sunk in the countersunk hole to avoid interference between the mounting plate 1 and the desktop or tabletop; and the fixing nut 43 moves downward to press against the top side of the mounting plate 1, thereby fixing the fixing stud 4; to ensure the stability of the fixing stud 4.
[0063] In some other embodiments, a threaded hole is provided on the end face of the fixing stud 4 connected to the mounting plate 1, and a screw is passed through the side of the mounting plate 1 facing away from the support arm 2 and toward the support arm 2. The screw is threadably matched with the threaded hole, and the head of the screw abuts against the side of the mounting plate 1 facing away from the adjusting nut 40.
[0064] In actual situations, a threaded hole can also be set on the bottom end face of the fixing stud 4, and a screw can be penetrated on the mounting plate 1 in the form of a countersunk hole. The screw can be tightened with the threaded hole, which can also fix the fixing stud 4 and ensure its stability.
[0065] In some other embodiments, at least two adjusting mechanisms are provided, and the two fixing studs 4 of two adjacent adjusting mechanisms are arranged at intervals.
[0066] Specifically, in reality, the situation that may exist is: the distance between two contacts to be tested on the circuit board is large, so that when the probe 3 is adjusted in different mounting holes 21, it cannot meet the effective contact of the contacts. Therefore, in some embodiments, a plurality of adjustment mechanisms can be provided on the mounting plate 1, and the fixing studs 4 in each adjustment mechanism can be arranged at intervals, so that when testing a group of contacts with a large distance to be tested, probes 3 in different adjustment mechanisms can be used respectively, thereby ensuring effective detection; at the same time, under the action of multiple groups of adjustment mechanisms, the range that the probe 3 can cover will also be larger, and the adaptability of the entire device is also improved.
[0067] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
