Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a novel fault indicator assembly and testing tooling. Background Art

[0002] The fault indicator requires the installation of a large clamp and a small clamp. A torsion spring is installed on the swivel where the clamp limit hole of the new fault indicator is located to make the clamp clamp tight. Therefore, a lot of force is required to install the clamp, and uneven installation force often occurs during manual installation, so that the torsion spring often pops out or deviates, which poses certain safety hazards and may cause irreversible deformation of the torsion spring and become scrapped; in addition, the positioning of the limit hole is not accurate enough during manual installation of the clamp, making it difficult to install the pin, and the existing PCB burning and testing tooling is simple, and the contact area of ​​the vias is small when the cable pins are inserted into the PCB circuit, and poor wiring between the tooling and the motherboard often leads to burning failures and no response to the test connection. Utility Model Content

[0003] The utility model discloses a novel fault indicator assembly and testing tool with a simple structure and convenient operation, aiming to improve the above-mentioned problems.

[0004] The utility model adopts the following scheme:

[0005] A new type of fault indicator assembly and testing tool, including a base, on which is provided a fixing seat, a probe assembly, a first tightening assembly, a second tightening assembly and a pin, wherein the fixing seat is suitable for fixing the fault indicator shell body to the base; the first tightening assembly includes a pressure block with a first groove to press two large clamps onto the fault indicator at a fixed angle from the oblique upper part of the fault indicator, and the second tightening assembly includes a pressure block with a second groove to press two small clamps onto the fault indicator at a fixed angle from the horizontal side, thereby accurately aligning the pin holes of the large clamps and the small clamps with the limiting holes of the shell body; the pin is suitable for fixing the pressure plate on the fault indicator; the probe assembly is arranged on the base to respectively connect the mainboard burning port arranged at the bottom of the fault indicator and the test point connected to the power supply of the whole machine, so as to perform functional testing in the clamped state.

[0006] Furthermore, the first tightening assembly includes a first travel slide rail obliquely arranged on one side of the fixed seat, and a first fixed pressure block with a first groove is provided at one end of the first travel slide rail close to the fixed seat, and a first operating handle is provided at the other end. The first fixed pressure block is suitable for moving along the direction of the first travel slide rail under the control of the first operating handle to tighten the first groove on the large clamp, so that the pin hole on the large clamp is precisely aligned with the limiting hole of the shell body.

[0007] Furthermore, the second tightening assembly is arranged on the opposite side of the projection surface of the first tightening assembly, and includes a second travel slide rail arranged on the other side of the fixed seat, and the second travel slide rail is provided with a second fixed pressure block with a second groove at one end close to the fixed seat, and a second operating handle is provided at the other end. The second fixed pressure block is suitable for moving along the direction of the second travel slide rail under the control of the second operating handle to tighten the second groove on the small clamp, so that the pin hole on the small clamp is precisely aligned with the limiting hole of the shell body.

[0008] Furthermore, two of the first fixed pressing blocks and two of the second fixed pressing blocks are provided, and are used to compress the two large clamps and the small clamp respectively.

[0009] Furthermore, the latches are arranged on the other two opposite sides of the fault indicator and are perpendicular to the second tightening assembly to respectively fix the pressure plates on the fault indicator for the clamp locking action.

[0010] Furthermore, the probe assembly includes a program burning contact probe suitable for connecting to the mainboard burning port and a power consumption test probe suitable for connecting to the power supply test point of the whole machine. The program burning contact probe and the power consumption test probe are arranged below the fixing seat so as to be connected to the mainboard burning port and the power supply test point on the fault indicator after the fault indicator is fixed in the fixing seat.

[0011] Beneficial effects:

[0012] This solution ensures the integrated installation of the fixture by customizing the grooves of the fixed pressure block to fit closely to the rotating parts of the large fixture and the small fixture, reducing irreversible damage to the torsion spring and safety hazards; the shell body uses the first tightening component, the second tightening grip, the pressure plate fixing pin and the fixing seat with a foolproof mouth to ensure the multiple limits required for the up, down, left, right, front and back of the fault indicator main shell, ensuring that the pin holes of the fixture and the limit holes of the shell body are accurately aligned to facilitate the subsequent installation of the fixture pins. During the fixing process, the multiple limits of the fault indicator shell body when installing the fixture can make the fault indicator accurately contact with the test probe and the burning probe, reducing the inaccurate hole docking caused by processing errors. At the same time, a variety of handles and pins are pressed on the shell body, so that the spring probe can be in close contact, thereby reducing the problems of low program burning success rate and cumbersome test wiring.

DETAILED DESCRIPTION

[0021] Combine Figures 1 to 7 As shown, this embodiment provides a new type of fault indicator assembly and testing tool, including a base 2, on which a fixing seat 21, a probe assembly, a first tightening assembly, a second tightening assembly and a pin 4 are provided, wherein the fixing seat 21 is suitable for fixing the shell body 11 of the fault indicator 1 on the base 2; the first tightening assembly includes a pressing block with a first groove 24 to press two large clamps 12 on the fault indicator 1 at a fixed angle from the oblique upper side of the fault indicator 1, and the second tightening assembly includes a pressing block with a second groove 33 to press two small clamps 13 on the fault indicator 1 at a fixed angle from the horizontal side, thereby accurately aligning the pin holes of the large clamps 12 and the small clamps 13 with the limiting holes 14 of the shell body 11; the pin 4 is suitable for fixing the pressure plate 16 on the fault indicator 1; the probe assembly is arranged on the base 2 to connect the mainboard burning port and the whole machine power supply test point respectively provided at the bottom of the fault indicator 1, so as to perform functional testing in the clamped state.

[0022] Combine Figures 1 to 3As shown, in this embodiment, the fault indicator 1 includes a main body 11 housing. Limiting holes 14 are provided above both sides of the main body 11 housing. These limiting holes 14 are used to install a large clamp 12 and a small clamp 13. Each side is provided with a large clamp 12 and a small clamp 13, and the large clamp 12 and the small clamp 13 face opposite directions. Each large clamp 12 and small clamp 13 is provided with a torsion spring 15 to maintain preload and elasticity. A pressure plate 16 is provided below each clamp on each side for clamp locking.

[0023] Combine Figures 4 to 7As shown, the fixing seat 21 is provided with an anti-stuck opening, which can facilitate the direct insertion of the fault indicator 1 and quick positioning. The first tightening assembly is arranged on one side of the fixing seat 21, and is tilted so as to tighten it at the corner of the large clamp 12. Specifically, the first tightening assembly includes a first travel slide 22 tilted on one side of the fixing seat 21, and the first travel slide 22 is provided with a first fixed pressure block 23 with a first groove 24 at one end close to the fixing seat 21, and a first operating handle 25 is provided at the other end. The first fixed pressure block 23 is suitable for moving along the direction of the first travel slide 22 under the control of the first operating handle 25 to tighten the first groove 24 on the large clamp 12, so that the pin hole on the large clamp 12 is precisely aligned with the limiting hole 14 of the shell body 11. The base 2 is provided with an inclined surface 26 on one side of the fixed seat 21. The first travel slide 22 is arranged on the inclined surface 26. A first handle fixing structure is provided on the path forming the slide to fix the first handle after tightening, maintaining the first fixed pressure block 23 in a fixed position. There are two first fixed pressure blocks 23, each of which is arranged in parallel and has a first groove 24 at the end for tightening against the swivel of the large clamp 12. In addition, the second tightening assembly is disposed on the opposite side of the projection surface of the first tightening assembly and includes a second travel rail 31 disposed on the other side of the fixed seat 21. A second fixed pressure block 32 with a second groove 33 is disposed at one end of the second travel rail 31, which is close to the fixed seat 21, and a second operating handle 34 is disposed at the other end. The second fixed pressure block 32 is adapted to move along the second travel rail 31 under the control of the second operating handle 34 to tighten the second groove 33 against the small clamp 13, so that the pin hole on the small clamp 13 is precisely aligned with the limiting hole 14 of the housing body 11. On the projection surface of the base 2, the first travel rail 22 and the second travel rail 31 can be aligned, so that the forces acting on the main body 11 of the fault indicator 1 during tightening can offset each other. The second travel rail 31 is disposed on the horizontal surface of the base 2 and is also connected to two parallel second fixed pressure blocks 32 at one end. Each fixed pressure block has a second groove 33 at one end, which is used to tighten against the swivel of the small clamp 13. At the same time, the second operating handle 34 can also be fixed in the path of the travel slide, thereby maintaining the fixed position of the second fixed pressure block 32. Since the torsion spring 15 is installed simultaneously when the large clamp 12 and the small clamp 13 are installed, the above structure can overcome the elastic force of the torsion spring 15 and accurately match the pin hole of the clamp with the limit hole 14 on the fault indicator 1, which helps to control the consistent position of the large clamp 12 and the small clamp 13. In addition, scales can be provided on both the first travel slide 22 and the second travel slide 31 to control the stroke of each pressing.

[0024] Combine Figures 4 to 7 As shown, the latch 4 is arranged on the other two sides opposite to the fault indicator 1 and is perpendicular to the second tightening assembly to respectively fix the pressure plate 16 on the fault indicator 1 for the clamp locking action. Here, the two latches 4 are arranged on the same straight line and are respectively inserted into the pressure plate 16 of the fault indicator 1 on opposite sides. When the clamp is installed, the pressure plate 16 is fixed to prevent the pressure plate 16 from affecting the installation of the clamp. In a preferred embodiment, an elastic part is provided on the latch 4, and the latch 4 can be inserted and withdrawn by pressing. The latch 4 can be used to support the pressure plate 16 when installing the clamp to prevent it from affecting the installation.

[0025] Combine Figure 4 and Figure 5 As shown, the probe assembly includes a program burning contact probe 51 suitable for connecting to the mainboard burning port and a power consumption test probe 52 suitable for connecting to the power supply test point of the entire machine. The program burning contact probe 51 and the power consumption test probe 52 are arranged below the fixing seat 21 to connect to the mainboard burning port and the power supply test point on the fault indicator 1 after the fault indicator 1 is fixed in the fixing seat 21. A power access port 53 is provided on the base 2 to provide a standard source current to the fault indicator 1 as a whole, and a test access port 54 is also provided for connecting an external test instrument to test power consumption; the base 2 is also provided with a program burning access port 55 for connecting to a program burner. A power switch 56 is also included to turn on the power to enter the test after the burner is installed.

[0026] During operation, the fault indicator 1 housing body 11 with the PCB motherboard and locked is installed in the fixing seat 21 according to the anti-foolproof opening; four clamps and the pressure plate 16 are installed in the preset groove of the housing body 11, and the front and rear pins 4 are inserted into the two sides of the housing of the main body 11 of the fault indicator 1 to fix the pressure plate 16; then the two large clamps 12 are pressed into the corresponding positions of the housing body 11 of the fault indicator 1 using the first operating handle 25, so that the pin hole positions of the large clamps 12 are aligned with the corresponding limit holes 14, and the pins are inserted to fix them; then the two small clamps 13 are pressed into the corresponding positions of the housing body 11 using the second operating handle 34, so that the pin hole positions of the small clamps 13 are aligned with the corresponding limit holes 14, and the pins are inserted to fix them, thereby completing the installation of the clamp clamping mechanism on the fault indicator 1. Then, without releasing the operating handles on both sides, use the burner to connect the program burning access port 55 of the base 2 and the computer to burn the program to the mainboard, then connect the multimeter to the test access port 54, and finally turn on the power switch 56 to read the current parameters to complete the power consumption test of the entire machine.

[0027] The new fault indicator 1 provided in this embodiment utilizes the setting of fixed pressure blocks, latches 4 and fixed seats 21 to allow the shell body 11 to have multiple limits, reducing errors when installing into the fixture, so that the large and small fixtures 13 stuck in the pressure block grooves can be pressed into the shell alignment holes of the indicator body 11 more accurately along the direction of the slide rail, making it convenient for the subsequent insertion of pins; by reusing the fixed pressure blocks on the tooling, multiple production processes can be carried out simultaneously.
