Description

Technical Field

[0001] This utility model relates to the field of bending probe technology, and in particular to a fixture for assisting in the insertion of bending probes. Background Technology

[0002] In the fields of electronic components, semiconductor packaging, and PCB board testing, it is often necessary to use probes (commonly known as "bent probes") with specific bending angles (such as 90 degrees or other non-vertical angles) for electrical contact or signal transmission testing. These bent probes typically include, from bottom to top, a first vertical section for contacting the component under test, a bent section, and a second vertical section for applying force. However, there are significant technical challenges in mounting such bent probes onto test fixtures or using them directly for insertion testing.

[0003] Conventionally, there are two ways for operators to insert bent probes. One method involves the operator inserting the bottom end of the probe sequentially through the insertion holes from top to bottom, thus connecting the bottom end of the probe to the component under test. Obviously, during the probe insertion process, the bent section of the probe cannot smoothly pass through the straight insertion holes on the top support plate, and may even twist the bent section of the probe. Therefore, operators rarely use this method to insert bent probes. The other method involves the operator inserting the bottom end of the probe into the insertion hole on the bottom support plate, and then inserting the top end of the probe into the insertion hole on the top plate. Similarly, this manual operation has the problem of three-dimensional alignment: inserting a single probe is time-consuming and prone to inaccuracy. Furthermore, the bent section of the probe is prone to change its curvature due to repeated stress during the operation, which seriously restricts the testing efficiency and reliability. Therefore, the existing technology lacks an auxiliary fixture that can effectively, quickly, and stably perform insertion tests on bent probes. Utility Model Content

[0004] The main purpose of this invention is to provide a fixture for assisting in the insertion of bent probes, which aims to solve the problem of the difficulty in quickly and accurately inserting bent probes.

[0005] To achieve the above objectives, this utility model proposes a fixture for assisting in the insertion of a bending probe, comprising a probe, wherein the probe comprises, from bottom to top, a first vertical segment, a bent segment extending from the top of the first vertical segment, and a second vertical segment parallel to the first vertical segment, and the fixture comprises:

[0006] The first support plate is provided with a first insertion hole;

[0007] A second support plate is disposed on top of the first support plate, and the second support plate is provided with a limiting channel capable of accommodating a plurality of the bending segments;

[0008] A guide member is detachably mounted on the top of the second support plate. The center of the first insertion hole is offset by a set distance relative to the center of the second insertion hole in the bending direction of the curved section. When the curved section passes through the second insertion hole and moves in the limiting channel, such that the top of the curved section contacts the outlet end of the second insertion hole, the lower end of the first vertical section is fully inserted into the first insertion hole to form a pre-positioned state, while the second vertical section is suspended and positioned at a preset height.

[0009] The third support plate is provided with a third insertion hole. The third support plate is sleeved with the corresponding second vertical segment through the third insertion hole to be installed on the top of the second support plate.

[0010] Preferably, the top of the second support plate is provided with a boss surrounding the entrance end of the limiting channel, the guide is stacked on the boss, and the guide is installed on the boss by a number of first fasteners.

[0011] Preferably, the first fastener includes a first fastening screw;

[0012] The top of the boss is provided with a plurality of threaded holes, which are evenly distributed around the limiting channel. The guide is provided with a through hole corresponding to the threaded hole. The guide is fastened to the boss by threading the through hole and the threaded hole through the first fastening screw.

[0013] Preferably, the third support plate has a recessed mounting groove on the side facing the guide member to accommodate the guide member and the boss;

[0014] The third support plate is also provided with a disassembly hole corresponding to the through hole.

[0015] Preferably, the guide member includes a guide plate.

[0016] Preferably, the first support plate and the second support plate are connected by a plurality of second fasteners.

[0017] Preferably, the second fastener includes a second fastening screw.

[0018] Preferably, the inlet end of the second insertion hole is chamfered.

[0019] The beneficial effects of this utility model are as follows: This fixture utilizes a directional offset design between the center of the first insertion hole and the center of the second insertion hole. The offset direction is consistent with the bending direction of the bending segment. Combined with the constraint of the free trajectory of the bending segment by the limiting channel, when the top of the bending segment moves to the outlet end of the second insertion hole, the lower end of the first vertical segment is simultaneously fully inserted into the first insertion hole to form a fixed end. This allows the second vertical segment to be suspended and positioned at a preset height to form a socket end. At this time, both ends of the bent probe are synchronously pre-positioned, so that the second vertical segment of the probe is in a pre-positioned state. The above operation is simple. Using the guide design, the positions of the probe bending segment and the first vertical segment are first stabilized, and then the positions of several second vertical segments are uniformly fixed using the third support plate, thereby quickly completing the assembly of the probe and the component under test. During the above operation, there is no need to apply force to the probe bending segment. Therefore, this fixture design also improves the stability and reliability of the contact between the probe and the component under test, realizes the accurate transmission of test signals, reduces test errors and the risk of probe damage, and improves test efficiency.

[0037] This utility model provides a fixture for assisting in the insertion of bending probes. Please refer to [reference needed]. Figures 1-4The fixture includes a probe 100, which, from bottom to top, comprises a first vertical segment 101, a curved segment 102 extending from the top of the first vertical segment 101, and a second vertical segment 103 parallel to the first vertical segment 101. The fixture includes a first support plate 1, a second support plate 2, a guide member 3, and a third support plate 4. The first support plate 1 has a first insertion hole 11. The second support plate 2 is disposed on top of the first support plate 1 and has a limiting channel 21 capable of accommodating several curved segments 102. The guide member 3 is detachably disposed on top of the second support plate 2 and has a second insertion hole 31 communicating with the limiting channel 21. The center of the first insertion hole 11 is offset by a set distance relative to the center of the second insertion hole 31 in the bending direction of the curved segment 102. When the curved segment 102 passes through the second insertion hole 31 and moves within the limiting channel 21, the top of the curved segment 102 contacts the second insertion hole 31. When the probe is in the opening position, the lower end of the first vertical segment 101 is fully inserted into the first insertion hole 11 to form a pre-positioned state, while the upper end of the second vertical segment 103 is suspended and positioned at a preset height. The third support plate 4 is provided with a third insertion hole 41. The third support plate 4 is fitted with the corresponding second vertical segment 103 through the third insertion hole 41 to be installed on the top of the second support plate 2. This fixture utilizes the directional offset design of the center of the first insertion hole 11 relative to the center of the second insertion hole 31, combined with the constraint of the free trajectory of the bending segment 102 by the limiting channel 21, so that when the top of the bending segment 102 moves to the outlet end of the second insertion hole 31, the lower end of the first vertical segment 101 is simultaneously fully inserted into the first insertion hole 11 to form a fixed end, thereby making the second vertical segment 103 suspended and positioned at a preset height to form a waiting end. At this time, the bending probe 100 is pre-positioned at both ends simultaneously. The above settings make the second vertical segment 103 of the probe 100 in a pre-positioned state.

[0038] The above structure is simple to operate; please refer to it. Figures 2-4 First, by using the guide component 3, the position of the bent section 102 and the first vertical section 101 of the probe 100 is stabilized by the insertion pin. Then, by operating the third support plate 4, the positions of several second vertical sections 103 are uniformly fixed, thus quickly assembling the probe 100 with the component under test. During the above operation, the bent section 102 of the probe 100 does not need to be stressed, which improves the stability and reliability of the contact between the probe 100 and the component under test, realizes the accurate transmission of test signals, reduces test errors and the risk of damage to the probe 100, and improves test efficiency.

[0039] To ensure that probe 100 does not jam during testing, please refer to the following: Figure 3In this embodiment, the top of the second support plate 2 is provided with a boss 22 surrounding the entrance end of the limiting channel 21. The guide member 3 is stacked on the boss 22 and is installed on the boss 22 by several first fasteners 5. The third support plate 4 has a recessed mounting groove 43 on the side facing the guide member 3 to accommodate the guide member 3 and the boss 22. Specifically, the guide member 3 is placed on the top of the boss 22. It should be noted that there is a gap in the vertical direction between the top of the guide member 3 and the bottom of the mounting groove 43. Please refer to [reference needed] for details. Figure 4 The gap is represented by M; when the first fastener 5 is removed and the fixed connection between the boss 22 and the guide 3 is released, the guide 3 can float up and down in the gap through the movement of the probe 100, so that the bent section 102 of the probe 100 can smoothly recover its elastic deformation.

[0040] Following on from the above, please refer to... Figure 3 and Figure 4 In this embodiment, the first fastener 5 includes a first fastening screw. The top of the boss 22 is provided with a plurality of threaded holes 221, which are evenly distributed around the limiting channel 21. The guide 3 is provided with a through hole 32 corresponding to the threaded hole 221. The guide 3 is fastened to the boss 22 by threading the first fastening screw into the through hole 32 and the threaded hole 221. The third support plate 4 is also provided with a disassembly hole 42 corresponding to the through hole 32. When the third insertion hole 41 on the third support plate 4 is sleeved with the second vertical segment 103 of the corresponding probe 100, the disassembly hole 42 will communicate with the corresponding through hole 32. Therefore, the operator can use the disassembly hole 42 to remove the first fastening screw from the threaded hole 221, thereby releasing the fixed connection between the guide 3 and the boss 22.

[0041] In other embodiments, the first fastener 5 includes screws, etc.

[0042] In this embodiment, there are several probes 100. The number of first insertion holes 11, second insertion holes 31, and third insertion holes 41 are all adapted to the number of probes 100. This utility model uses the guide 3 to be fixed on the boss 22, so that after the first vertical segment 101 of the probe 100 passes through the second insertion hole 31, since the curved segment 102 of the probe 100 is an extension of the first vertical segment 101, the curved segment 102 will stably pass through the second insertion hole 31. The first vertical segment 101 will automatically insert into the corresponding first insertion hole 11, realizing the pre-positioning of the probe 100, thereby enabling several probes 100 to quickly complete the assembly before testing the component under test. This utility model also utilizes the floating nature of the guide 3 in the mounting groove 43, so that the probe 100 will not experience the problem of being stuck or unevenly stressed due to the second insertion hole 31 during the movement.

[0043] To ensure that the curved section 102 can be inserted into the second insertion hole 31 more smoothly, the entrance end of the second insertion hole 31 is provided with a chamfer (not shown).

[0044] In this embodiment, the guide 3 includes a guide piece; in other embodiments, the guide 3 may be a mesh structure.

[0045] Regarding the connection method of the first support plate 1 and the second support plate 2, please refer to... Figure 3 In this embodiment, after the second support plate 2 is stacked on top of the first support plate 1, the first support plate 1 and the second support plate 2 are connected by a number of second fasteners 6. Specifically, the second fastener 6 includes a second fastening screw. In other embodiments, the second fastener 6 may be a Velcro structure or a magnetic layer, etc.

[0046] For the installation procedure of this fixture, please refer to [link / reference]. Figures 1-4 First, the second support plate 2 is stacked on top of the first support plate 1, so that the limiting channel 21 on the second support plate 2 communicates with the first insertion hole 11. Then, the first support plate 1 and the second support plate 2 are fixedly connected by the second fastener 6. Next, the operator places the guide plate on the boss 22, so that the through hole 32 on the guide plate communicates with the corresponding threaded hole 221. The operator fastens the guide plate to the boss 22 by rotating the first fastening screw. At this time, the probe 100 is installed. During installation, the first vertical section 101 of the probe 100 is first inserted into the second insertion hole 31. The curved section 102 extending from the top of the first vertical section 101 smoothly passes into the second insertion hole 31 until all the curved sections 102 are located in the limiting channel 21. At this time, the first vertical section 101 and the first threaded hole 11 are connected. The probe 100 is inserted into the insertion hole 11, and the second vertical segment 103 is suspended and positioned above the guide plate. This operation stabilizes the positions of the curved segment 102 and the first vertical segment 101. At this time, the probe 100 is pre-fixed on the straight path. After several probes 100 have completed the above insertion action, the operator only needs to insert the third insertion hole 41 on the third support plate 4 into the corresponding second vertical segment 103, press down the third support plate 4 to cover the guide 3, and completely fix the position of the probe 100. Finally, the operator removes the first fastener 5 through the disassembly hole 42. The guide plate can then move up and down in the gap between the mounting groove 43 and the boss 22 as the probe 100 moves, so as to avoid the probe 100 getting stuck when the second vertical segment 103 of the probe 100 is under force.

[0047] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
