Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of probe connector, in particular to a probe connector fixing tool. BACKGROUND

[0002] The probe connector is a key component for electrical testing, widely used in the fields of semiconductor, electronic components, printed circuit board (PCB) and the like. Its core function is to realize the transmission of electrical signals through the physical contact between the probe and the test point, so as to complete the performance test of the measured object.

[0003] In the related art, when testing a plurality of regularly arranged test points, a plurality of probe connector units are regularly fixed on an outer shell, the spacing between the probe connector units is consistent with the spacing between the test points, so that the probe and the test point are one-to-one corresponding, thereby facilitating the simultaneous testing of a plurality of regularly arranged test points and improving the testing efficiency.

[0004] In the implementation of the present application, it is found that at least the following problems exist in the prior art: the spacing between the probe connector units is not variable, which limits the applicability of the probe connector in different testing scenarios; when changing the electronic components to be tested, the spacing of some test points is different, but the arrangement of the test points is similar, such as the common single-row arrangement and matrix arrangement, at this time, it is necessary to re-customize the outer shell of the probe connector and install the corresponding probe connector unit, which not only consumes time but also wastes resources. SUMMARY

[0005] In order to facilitate the adjustment of the spacing between the probe connector units and reduce the time consumption and resource waste caused by re-customizing the outer shell, the present application provides a probe connector fixing tool.

[0006] The probe connector fixing tool provided by the present application adopts the following technical solution:

[0007] A probe connector fixing tool, comprising an outer shell and a plurality of probe connector units, the outer shell is provided with a loading guide rail along the length direction, the loading guide rail is uniformly and spacedly provided with a plurality of mounting seats along the length direction, one of the mounting seats is fixedly connected with the loading guide rail, and the remaining mounting seats are slidably connected with the loading guide rail, the probe connector units are one-to-one corresponding and fixedly connected with the mounting seats, the outer shell is provided with a spacing adjustment mechanism, and the spacing adjustment mechanism is used to drive the slidable mounting seats to slide on the loading guide rail and fix the position of the mounting seats.

[0008] By adopting the above technical scheme, when the test points with changed intervals need to be tested, the operator can drive the slidable mounting seats to slide on the loading guide rail through the interval adjusting mechanism, so as to change the intervals between the mounting seats. The change of the intervals between the mounting seats means the change of the intervals between the probe connector units, and the intervals between the probes are also changed. In this way, the intervals between the probe connector units are adjusted, and the time consumption and resource waste caused by re-customizing the shell are reduced.

[0009] As a preferred, the interval adjusting mechanism comprises an adjusting guide rail, movable blocks, first connecting rods, second connecting rods and first interval adjusting assemblies. The adjusting guide rail is parallel to the loading guide rail and slides in the shell along the direction of approaching or moving away from the loading guide rail. The movable blocks are uniformly spaced along the length direction on the adjusting guide rail and slide. Each of the first connecting rods and the second connecting rods is arranged on each movable block. Each movable block corresponds to two adjacent mounting seats. In the movable block and the corresponding two mounting seats, one end of the first connecting rod is rotationally connected with one mounting seat, one end of the second connecting rod is rotationally connected with the other mounting seat, and the other ends of the first connecting rod and the second connecting rod are rotationally connected with the movable block. The first interval adjusting assembly is used to drive the adjusting guide rail to approach or move away from the loading guide rail.

[0010] By adopting the above technical scheme, when the test points with changed intervals need to be tested, the adjusting guide rail slides along the direction of approaching or moving away from the loading guide rail through the first interval adjusting assembly. Since the movable blocks and the two adjacent mounting seats are rotationally connected through the first connecting rods and the second connecting rods, when the interval between the adjusting guide rail and the loading guide rail decreases, the included angle between the first connecting rod and the second connecting rod increases, the distance between the mounting seats connected by the first connecting rod and the second connecting rod increases, and then the interval between the probe connector units increases, and the interval between the probes also increases. Conversely, when the interval between the adjusting guide rail and the loading guide rail increases, the included angle between the first connecting rod and the second connecting rod decreases, the distance between the connected mounting seats decreases, the interval between the probe connector units decreases, and the interval between the probes also decreases. In this way, the distances between all adjacent mounting seats are changed at the same time, and after the change, the intervals between the mounting seats are still equal.

[0011] As a preferred, the first interval adjusting assembly comprises a bracket and a first screw rod. The bracket is fixed in the shell, and the first screw rod is arranged along the width direction of the shell. The first screw rod is rotationally connected with the bracket and is threadedly connected with the adjusting guide rail.

[0012] By adopting the above technical scheme, when it is necessary to change the distance between the adjusting guide rail and the loading guide rail, the first screw rod is rotated, and since the first screw rod is rotationally connected with the support and is threadedly connected with the adjusting guide rail, the rotation of the first screw rod will be converted into the linear motion of the adjusting guide rail along the axial direction of the first screw rod (i.e. the direction of the width of the shell, that is, the direction of approaching or moving away from the loading guide rail), so as to change the distance between the adjusting guide rail and the loading guide rail.

[0013] As a preferred, the first screw rod is provided with one at each end of the adjusting guide rail, and the first distance adjusting assembly further comprises a worm, a worm wheel and a distance knob, the worm wheel is coaxial with the first screw rod and is fixedly connected with the first screw rod, the worm is arranged along the length direction of the shell and is rotationally connected with the shell, the end of the worm penetrates through the side wall of the shell and is fixedly connected with the distance knob, and the worm is meshingly connected with the two worm wheels.

[0014] By adopting the above technical scheme, the first screw rod is provided with one at each end of the adjusting guide rail, on the one hand, the driving force is applied to both ends of the adjusting guide rail, so as to improve the stability of the adjusting guide rail during movement, and on the other hand, the first screw rod is prevented from interfering with the movable block, when it is necessary to adjust the distance between the probe connector units, the distance knob is only needed to be rotated, the worm is synchronously rotated by the distance knob, the rotation of the worm will simultaneously drive the two worm wheels to rotate, and then the two first screw rods are synchronously rotated, so that the adjusting guide rail moves stably along the direction of approaching or moving away from the loading guide rail.

[0015] As a preferred, the loading guide rails are symmetrically arranged in the width direction of the shell, the adjusting guide rails are each provided with one on the side of the loading guide rails close to each other, the support is located between the two adjusting guide rails, the middle part of the first screw rod is rotationally connected with the support, and the two ends of the first screw rod are provided with two thread segments with equal thread pitch and opposite rotation direction, one of the thread segments is threadedly connected with one of the adjusting guide rails, and the other thread segment is threadedly connected with the other adjusting guide rail.

[0016] By adopting the above technical scheme, when the test points are arranged in a matrix, the two loading guide rails can simultaneously test the test points of two rows, so as to improve the test efficiency. When the first screw rod is rotated, the two adjusting guide rails on the two sides simultaneously approach or move away from the corresponding loading guide rails, and the moving distance is equal. The movable blocks on the adjusting guide rails are connected with the mounting seats on the loading guide rails through the first connecting rod and the second connecting rod, so that the synchronous movement of the two adjusting guide rails can drive the mounting seats on the two loading guide rails to synchronously change the distance. The distance between the two rows of probe connector units can be simultaneously adjusted, so as to improve the adjustment efficiency.

[0017] Preferably, the top of the housing has a movable groove along its length, and the top of the housing has a spacing scale line for reflecting the distance between adjacent mounting bases. A pointing block slides in the movable groove, and the pointing block points to the spacing scale line. A connecting frame slides on the pointing block along the width of the housing, and the connecting frame is fixedly connected to any movable block.

[0018] By adopting the above technical solution, when the operator uses the spacing adjustment mechanism to adjust the distance between adjacent mounting seats, the movement of the movable block on the adjustment guide rail will drive the connecting frame to move synchronously. Since the connecting frame and the pointing block slide along the width direction of the housing, the movement of the connecting frame will cause the pointing block to slide within the movable groove along the length direction of the housing. The operator can intuitively and accurately understand the change in distance between adjacent mounting seats by observing the value indicated by the pointing block on the spacing scale line.

[0019] Preferably, the loading guide rail can slide along the width direction of the housing, and the housing is also provided with a second adjusting component for driving the loading guide rails closer or further apart, and the second adjusting component can fix the position of the loading guide rail.

[0020] By adopting the above technical solution, when testing the test points of the matrix arrangement and the row spacing of the test points changes, the operator can use the second adjustment component to drive the two loading guide rails to move closer or further apart, thereby changing the row spacing between the two rows of mounting seats. Since the loading guide rails are moving closer or further apart, it is still possible to ensure that the distance between the loading guide rails and the corresponding adjustment guide rails is equal, thereby ensuring that the spacing of each row of mounting seats is equal.

[0021] Preferably, the second pitch adjustment assembly includes a second screw, a rack, and an intermediate gear. The second screw is arranged along the width direction of the housing and is threadedly connected to the end wall of the housing. The second screw is rotatably connected to any loading guide rail. The intermediate gear rotates on the side wall of the housing. There are two racks, one of which is fixedly connected to one of the loading guide rails and meshes with one side of the intermediate gear, and the other rack is fixedly connected to the other loading guide rail and meshes with the other side of the intermediate gear.

[0022] By adopting the above technical solution, when it is necessary to change the spacing of the loading guide rails, the second screw is rotated. Since the second screw is threadedly connected to the end wall of the housing, the second screw will drive one loading guide rail to slide along the width direction of the housing. The sliding of the loading guide rail will drive the rack connected to it to slide, which in turn drives the intermediate gear to rotate. The intermediate gear drives another rack to slide in the opposite direction, so as to further drive the other loading guide rail to slide, thereby driving the two loading guide rails to move closer or further apart.

[0023] Preferably, the top of the housing has a through-hole that extends through both the inside and outside. Several test leads are installed in the through-hole, and each test lead corresponds to and is electrically connected to a probe connector unit.

[0024] By adopting the above technical solution, the through-hole design allows test leads to easily pass through the housing and make electrical connections with the probe connector unit, ensuring the transmission of electrical signals. At the same time, the through-hole extends through both the inside and outside of the housing, facilitating the arrangement and management of test leads, minimizing clutter and interference during testing, and improving the stability and reliability of the test.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up a housing, probe connector, loading rail, mounting base, and spacing adjustment mechanism, the spacing between probe connector units can be adjusted, which can adapt to test points with different spacings. There is no need to customize the housing, which reduces time consumption and resource waste, and improves the applicability of probe connectors in different testing scenarios.

[0027] 2. By setting up an adjusting guide rail, a movable block, a first connecting rod, a second connecting rod, and a first pitch adjustment component, the adjusting guide rail can be stably driven to move closer to or further away from the loading guide rail, thereby driving the mounting base and probe connector unit to change the pitch synchronously, ensuring the accuracy and consistency of the pitch adjustment;

[0028] 3. By setting up movable slots, spacing scale lines, pointing blocks, and connecting brackets, operators can intuitively and accurately understand the spacing changes when adjusting the distance between adjacent mounting seats, which facilitates precise control of the spacing between probe connector units and improves the accuracy of testing.

[0034] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0035] Embodiment 1 of this application discloses a probe connector fixing fixture. (Refer to...) Figure 1 and Figure 2 The device includes a housing 1 and several probe connector units 2. A loading guide rail 3 is arranged along the length of the housing 1, and several mounting seats 31 are evenly spaced along the length of the loading guide rail 3. One mounting seat 31 is fixedly connected to the loading guide rail 3, while the remaining mounting seats 31 are slidably connected to the loading guide rail 3. Specifically, there are five mounting seats 31 on the loading guide rail 3, and the central mounting seat 31 is fixedly connected to the loading guide rail 3. The probe connector units 2 are fixedly connected to each mounting seat 31. A spacing adjustment mechanism 4 is provided inside the housing 1. The spacing adjustment mechanism 4 is used to drive the slidable mounting seats 31 to slide on the loading guide rail 3 and can fix the position of the mounting seats 31.

[0036] Reference Figure 1 and Figure 2 The top of the outer casing 1 has a through-hole 15 that extends from both inside and outside. Several test leads 22 are installed within the through-hole 15, each corresponding to and electrically connected to a probe connector unit 2. Specifically, the test leads 22 are electrically connected to the probe connector unit 2 via an SMA interface 21. The SMA interface 21 has excellent electrical and mechanical properties, ensuring the quality and accuracy of signal transmission. Using the SMA interface 21 minimizes the risk of unstable or broken connections between the probe connector unit 2 and the connecting wires during movement of the mounting base 31.

[0037] Reference Figure 2When it is necessary to test test points with altered spacing, the spacing adjustment mechanism 4 drives the sliding mounting base 31 to slide on the loading guide rail 3, thereby changing the spacing between each mounting base 31 and thus changing the spacing between the probes.

[0038] To facilitate the detection of test points arranged in multiple rows, refer to Figure 1 and Figure 2 A set of loading guide rails 3 are symmetrically arranged in the width direction of the outer casing 1. A set of fixed guide rails 16 are fixed on the two inner side walls of the outer casing 1 in the length direction. The fixed guide rails 16 are arranged along the width direction of the outer casing 1, and the loading guide rails 3 are slidably connected to the fixed guide rails 16.

[0039] Reference Figures 1 to 3 The outer casing 1 is also provided with a second adjusting assembly 5 for driving the loading guide rails 3 closer together or further apart, and the second adjusting assembly 5 can fix the position of the loading guide rails 3. The second adjusting assembly 5 includes a second screw 51, a rack 52, an intermediate gear 53, and a spacing knob 54. The second screw 51 is arranged along the width direction of the outer casing 1, passes through the end wall of the outer casing 1, and is threadedly connected to the end wall of the outer casing 1. The spacing knob 54 is located outside the outer casing 1 and is fixedly connected to the second screw 51. The second screw 51 is rotatably connected to any one of the loading guide rails 3, and the intermediate gear 53 rotates on the inner side wall of the outer casing 1. There are two racks 52, one of which is fixedly connected to one of the loading guide rails 3 and meshes with one side of the intermediate gear 53, and the other rack 52 is fixedly connected to the other loading guide rail 3 and meshes with the other side of the intermediate gear 53.

[0040] Reference Figure 2 and Figure 3 When it is necessary to change the spacing of the loading guide rails 3, the second screw 51 is rotated. The second screw 51 drives one loading guide rail 3 to slide along the width direction of the housing 1. The rack 52 connected to the loading guide rail 3 moves accordingly, thereby driving the intermediate gear 53 to rotate. The intermediate gear 53 drives another rack 52 to slide in the opposite direction, so as to further drive the other loading guide rail 3 to slide, thereby driving the two loading guide rails 3 to move closer or further apart, thereby adjusting the row spacing of the probes of the probe connector unit 2.

[0041] In addition, refer to Figure 1 and Figure 2 The end wall of the outer casing 1 has a scale rod 55 that runs through and slides, and the scale rod 55 is provided with a row spacing scale line 56. The scale rod 55 is fixedly connected to any loading guide rail 3, and the outer end face of the end wall of the outer casing 1 points to the row spacing scale line 56. The row spacing of the probe connector unit 2 can be easily read directly through the row spacing scale line 56.

[0042] To facilitate the synchronous sliding of all sliding mounting bases 31, refer to Figure 2and Figure 4 The spacing adjustment mechanism 4 includes an adjustment guide rail 41, a movable block 42, a first connecting rod 43, a second connecting rod 44, and a first spacing adjustment component 45. The adjustment guide rail 41 is parallel to the loading guide rail 3. The adjustment guide rail 41 slides within the housing 1 in a direction that is close to or away from the loading guide rail 3. One adjustment guide rail 41 is provided on each side of a set of loading guide rails 3 that are close to each other.

[0043] Reference Figures 1 to 4 The first pitch adjustment assembly 45 is used to drive the adjustment guide rail 41 closer to or further away from the loading guide rail 3. Specifically, the first pitch adjustment assembly 45 includes a bracket 451, a first screw 452, a worm gear 453, a worm wheel 454, and a pitch knob 455. The bracket 451 is fixed inside the housing 1 and located between the two adjustment guide rails 41. The first screw 452 is arranged along the width direction of the housing 1 and is rotatably connected to the bracket 451. The two ends of the first screw 452 have two threaded sections with equal pitch and opposite directions of rotation. One threaded section is threadedly engaged with one of the adjustment guide rails 41, and the other threaded section is threadedly engaged with the other adjustment guide rail 41. The worm wheel 454 is coaxial with and fixedly connected to the first screw 452. The worm gear 453 is arranged along the length direction of the housing 1 and is rotatably connected to the housing 1. The end of the worm gear 453 penetrates the side wall of the housing 1 and is fixedly connected to the pitch knob 455. The worm gear 453 is meshed with the two worm wheels 454.

[0044] Reference Figure 2 and Figure 4 The movable blocks 42 are evenly spaced and slide along the length of the adjusting guide rail 41, and their number is one less than that of the mounting bases 31. Specifically, there are four movable blocks 42 on the adjusting guide rail 41. One first connecting rod 43 and one second connecting rod 44 are each provided on each movable block 42. Each movable block 42 corresponds to two adjacent mounting bases 31. In the relationship between the movable block 42 and the two corresponding mounting bases 31, one end of the first connecting rod 43 is rotatably connected to one of the mounting bases 31, one end of the second connecting rod 44 is rotatably connected to the other mounting base 31, and the other ends of both the first connecting rod 43 and the second connecting rod 44 are rotatably connected to the movable block 42.

[0045] Reference Figures 1 to 4 When it is necessary to test the test points where the spacing changes, rotate the spacing knob 455. The spacing knob 455 drives the worm gear 453 to rotate synchronously. The rotation of the worm gear 453 will simultaneously drive the two worm wheels 454 to rotate, which in turn drives the two first screws 452 to rotate synchronously, so that the adjusting guide rail 41 moves smoothly along the direction of approaching or moving away from the loading guide rail 3.

[0046] Reference Figure 4When the distance between the adjusting guide rail 41 and the loading guide rail 3 decreases, the angle between the first connecting rod 43 and the second connecting rod 44 increases, the distance between the connected mounting seats 31 increases, the distance between the probe connector units 2 increases, and the distance between the probes also increases. Conversely, when the distance between the adjusting guide rail 41 and the loading guide rail 3 increases, the angle between the first connecting rod 43 and the second connecting rod 44 decreases, the distance between the connected mounting seats 31 decreases, the distance between the probe connector units 2 decreases, and the distance between the probes also decreases. This simultaneously changes the distance between all adjacent mounting seats 31, while maintaining the same spacing between the mounting seats 31 after the change.

[0047] Reference Figure 1 and Figure 2 The top of the outer casing 1 has a movable groove 11 along its length. A spacing scale 12, indicating the distance between adjacent mounting bases 31, is also provided on the top of the outer casing 1. A guide block 13 slides within the movable groove 11, pointing towards the spacing scale 12. A connecting frame 14 slides along the width of the outer casing 1 on the guide block 13, and is fixedly connected to any movable block 42. When the distance between the mounting bases 31 is adjusted, the movement of the movable block 42 on the adjusting guide rail 41 causes the connecting frame 14 to move synchronously. The movement of the connecting frame 14 causes the guide block 13 to slide within the movable groove 11 along the length of the outer casing 1. The operator can observe the value indicated by the guide block 13 on the spacing scale 12.

[0048] The implementation principle of a probe connector fixing fixture in this application embodiment is as follows: When testing test points arranged in multiple rows, the second screw 51 is rotated first. The second screw 51 drives a loading guide rail 3 to slide along the width direction of the outer shell 1. The rack 52 connected to the loading guide rail 3 moves accordingly, thereby driving the intermediate gear 53 to rotate. The intermediate gear 53 drives another rack 52 to slide in the opposite direction, further driving the other loading guide rail 3 to slide. The spacing between the two loading guide rails 3 is adjusted in this way, and the accuracy of the adjustment is confirmed by the row spacing scale line 56.

[0049] Next, rotating the spacing knob 455 causes the worm gear 453 to simultaneously drive the two worm wheels 454 to rotate, which in turn drives the two first screws 452 to rotate synchronously, causing the adjusting guide rail 41 to move closer to or further away from the loading guide rail 3. When the spacing between the adjusting guide rail 41 and the loading guide rail 3 decreases, the angle between the first connecting rod 43 and the second connecting rod 44 increases, the distance between the mounting seats 31 connected to the first connecting rod 43 and the second connecting rod 44 increases, and the spacing between the probes of the probe connector unit 2 also increases. Conversely, when the spacing between the adjusting guide rail 41 and the loading guide rail 3 increases, the angle between the first connecting rod 43 and the second connecting rod 44 decreases, the distance between the connected mounting seats 31 decreases, and the spacing between the probes of the probe connector unit 2 also decreases. This simultaneously changes the distance between all adjacent mounting seats 31, while maintaining the same spacing between the mounting seats 31 after the change. This changes the spacing between each mounting seat 31, thereby changing the spacing between the probes. This reduces the time and resource waste associated with customizing the housing 1.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
