Description

Technical Field

[0001] This invention relates to an electrical object and a fixture for detecting the electrical properties of the object, and particularly to a fixture for detecting the electrical properties of an object and its operating method. Background Technology

[0002] The term "electrical device" refers to a device that generally requires a power source to perform its intended function (such as a server). When such devices are nearly completed in production, they usually need to undergo electrical testing to ensure the product yield.

[0003] Furthermore, it is known that such electrical objects generally have at least one exposed electrical connection port. When performing electrical testing, the electrical connection port of the object must be connected to the test socket provided by the electrical testing device in order to facilitate power-on testing.

[0004] Currently, manufacturers have specialized fixtures for testing the electrical properties of objects. These fixtures are equipped with electrical testing devices that have test sockets and electrical connections. Typically, the object to be tested can be placed in a slot of the fixture by human or automated arm. A servo motor drives a worm gear to generate a thrust, which drives the object to be tested in the slot, so that the electrical connection port can be engaged with the test socket, thereby performing electrical testing on the object before it leaves the factory.

[0005] However, since electrical objects contain sophisticated electronic components, they are not suitable for being subjected to excessive force, so as to avoid damage to the electronic components and their structure.

[0006] As described above, the way in which the electrical connection port and the detection socket are interlocked is achieved by pushing the object with the thrust generated by the worm gear driven by the servo motor; however, this thrust is more likely to cause pressure on the electrical object, especially when the alignment accuracy between the electrical connection port and the detection socket is not good, which can easily cause damage to the conductive terminals or contacts, so it is urgent to improve it. Summary of the Invention

[0007] In view of the technical problems existing in the prior art, the object of the present invention is to provide an electrical testing fixture for an object and its operating method, specifically employing a compressible force to replace the thrust generated by the servo motor drive worm gear, thereby protecting the conductive terminals or contacts from damage during electrical connection. Furthermore, another aspect of the present invention employs an elastic force to resist the compressible force, and makes the compressible force greater than the elastic force, to further protect the conductive terminals or contacts from damage during electrical connection.

[0008] To this end, the present invention provides an electrical testing fixture for an object, comprising a base, a placement seat, and an inflatable airbag; the base is configured with at least one detection connector and an electrical testing device electrically connected to the detection connector; the placement seat is reciprocated by a driver and is slidably mounted on the base in an outward and inward manner; when the placement seat is outward, it provides a place for the object to be tested for electrical properties; and when the placement seat is inward, it allows at least one electrical connection port of the object to be exposed adjacent to the detection connector above; the airbag is disposed in the base and connected to an air source via an air inlet, the air source being able to inflate the airbag and generate a compressible force, the airbag transmitting the compressible force to drive at least one of the electrical connection ports of the object and the detection connector to electrically engage with each other.

[0009] In a further embodiment, the placement base is equipped with multiple elastic elements on both sides. The object resists the compressible force by an elastic force generated by these multiple elastic elements, and the compressible force is greater than the elastic force. Furthermore, the air source is a high-pressure air source, equipped with a proportional control valve capable of sensing the high-pressure air pressure value. The base is also equipped with a pressure sensor capable of sensing the pressure value when at least one of the electrical connection ports and the detection port are electrically engaged. A control unit is electrically connected between the proportional control valve and the pressure sensor to detect and control the compressible force. In a further embodiment, the placement base slides onto the base via a slide block, and the actuator is disposed on the base and drivenly connected to the slide block.

[0010] In a further implementation, multiple elastic elements are respectively arranged between the two sides of the placement base and the slide. The object resists the compressible force by an elastic force generated by the multiple elastic elements, and the compressible force is greater than the elastic force. Furthermore, the air source is a high-pressure air source, which is equipped with a proportional control valve capable of sensing the high-pressure air pressure value. The base is also equipped with a pressure sensor capable of sensing the pressure value when at least one of the electrical connection ports and the detection port are electrically interlocked. A control unit is electrically connected between the proportional control valve and the pressure sensor to detect and control the compressible force.

[0011] In a further embodiment, multiple elastic elements are helical springs, and a column for guiding the helical springs is arranged between the two sides of the placement seat and the slide.

[0012] In a further implementation, the base is provided with a pair of guide members, and the airbag is integrally connected to a pressure plate, which receives the guidance of the pair of guide members to transmit the compressible force to drive the object.

[0013] In a further embodiment, the pressure plate is configured with a pair of multiple pressure bars, and the object is provided with a pair of multiple compressive ends around its periphery. The pressure plate transmits the compressible force to the object by pressing the multiple compressive ends against the multiple pressure bars.

[0014] In the above implementation, the driving direction of the compressible force generated by the airbag is the same as the direction in which the electrical connection port and the detection socket can be electrically connected to each other. Furthermore, the driving direction of the compressible force generated by the airbag is perpendicular to the direction in which the actuator reciprocates to push the placement seat outward and inward.

[0015] In a further implementation, the air source is a high-pressure air source, which is equipped with a proportional control valve that can sense the high-pressure air pressure value. The base is also equipped with a pressure sensor that can sense the pressure value when at least one of the electrical connection ports and the detection socket are electrically connected to each other. The proportional control valve and the pressure sensor are electrically connected to a control unit for detecting and controlling the compressible force.

[0016] In a further implementation, the air source is a high-pressure air source, which is equipped with a proportional control valve capable of sensing the high-pressure air pressure value. The base is also equipped with a pressure sensor capable of sensing the pressure value when at least one of the electrical connection ports and the detection socket are electrically interlocked. A control unit is electrically connected between the proportional control valve and the pressure sensor to detect and control the compressible force.

[0017] The present invention further provides a method for operating the above-mentioned electrical testing fixture, comprising: suspending an object in the fixture, and using high-pressure air to drive an airbag to generate a compressible force to move the object, causing at least one electrical connection port of the object to be engaged with a testing socket having electrical conductivity within the fixture. The object resists the compressible force by bearing an elastic force, and the compressible force is greater than the elastic force.

Detailed Implementation

[0025] First, please refer to both. Figures 1 to 3 The diagram discloses an electrical testing fixture for an object provided by the present invention, comprising a base 10, a placement seat 20, and an inflatable airbag 30. The base 10 is assembled from metal frame plates, forming an integrally connected top chamber 11, a middle chamber 12, and a bottom chamber 13. The top chamber 11 houses the airbag 30, the middle chamber 12 houses the placement seat 20, and the bottom chamber 13 is connected to a plate 14 at the bottom of the base 10, housing at least one detection connector 15 and an electrical testing device 16 electrically connected to the detection connector 15. The detection connector 15 has a plurality of energized conductive terminals or contacts; the electrical testing device 16 includes electronic components that provide adaptive current to the detection connector 15, and may also include a pressure sensor.

[0026] like Figure 1 As shown, the placement seat 20 forms a slot frame 21 and upright walls 22 on both sides of the slot frame. A frame hole 211 is formed at the bottom of the slot frame 21, allowing the detection connector 15 of the bottom compartment 13 to be exposed to the central compartment 12 through the frame hole 211. For example... Figure 2 As shown, the placement base 20 can provide a place for an object 40 to be tested for electrical properties via the slot frame 21. The object 40 can be a server or other object that requires a power supply to perform a predetermined function, and the bottom of the object 40 has at least one electrical connection port 41 for electrically connecting to the detection base 15 (e.g., ...). Figure 4As shown), the electrical connection port 41 also has a number of conductive terminals or contacts that can be energized.

[0027] In a preferred implementation, such as Figure 1 and Figure 2 The placement seat 20 is disclosed to be slidable into the central compartment 12 of the base 10 via a slide 23. Furthermore, the slide 23 is a hollow quadrilateral frame formed by two side walls 231 and a connecting wall 232. Sliding components such as slide rails are respectively arranged on both sides of the slide 23 via the side walls 231. Multiple free rotors 121 are pivotally mounted on both sides of the central compartment 12 to guide the side walls 231 of the slide 23. Moreover, a tongue 233 is formed on one side of the connecting wall 232, and one side wall 17 of the base 10 (such as...) Figure 2 (As shown) A drive 24 is provided, which may be made of a pneumatic cylinder. The slide 23 is connected to the cylinder rod 241 of the drive 24 via the tongue 233, so that the drive 24 can reciprocate to drive the slide 23. Figure 3 and Figure 4 The diagram shows outward and inward movement along the X-axis. Figure 1 and Figure 3 This reveals that the object 40 was not placed in the seat 20 when it was pushed outward. Figure 2 This reveals the state in which the object 40 is placed when the placement base 20 is pushed outward. Please refer to [further details]. Figure 4 Furthermore, it is revealed that when the placement seat 20 is retracted, the electrical connection port 41 of the object 40 is exposed adjacent to the detection seat 15 along the Z-axis.

[0028] In another preferred implementation, such as Figure 1 and Figure 2 It is revealed that multiple elastic elements 25 are respectively arranged between the upright walls 22 on both sides of the placement base 20 and the side walls 231 on both sides of the slide 23; furthermore, the multiple elastic elements 25 may be made of helical springs, and multiple posts 251 for guiding the helical springs are arranged between the upright walls 22 on both sides of the placement base 20 and the side walls 231 on both sides of the slide 23; with this configuration, the multiple elastic elements 25 can provide an upward elastic force F1 along the X-axis (e.g., ... Figure 5 (As shown) to the placement seat 20 and the object 40 already placed on the placement seat 20.

[0029] Please refer to the following: Figure 3 and Figure 4The airbag 30 is disclosed to be disposed within the top chamber 11 of the base 10; the airbag 30 may be made of a soft capsule that can be filled with gas, such as rubber, and has an air inlet 31 for connecting to an air source (not shown); the air source may be generated by high-pressure air supplied by an air supply line, and the air source is equipped with a proportional control valve (not shown) that can sense the high-pressure air pressure value. See also Figure 5 The invention discloses that a high-pressure air source fills and inflates the airbag 30, causing the airbag 30 to generate a compressible force F2 that drives the electrical connection port 41 and the detection connector 51 of the object 40 to electrically engage with each other. The elastic force F1 resists the compressible force F2, and the compressible force F2 is greater than the elastic force F1, allowing the electrical connection port 41 of the object 40 to flexibly engage with the detection connector 51 under spring pressure, thereby protecting the internal conductive terminals or contacts of the electrical connection port 41 and the detection connector 51 from damage.

[0030] Furthermore, the present invention can also electrically connect the aforementioned proportional control valve and pressure sensor via a control unit, wherein the pressure sensor is used to sense the pressure value when at least one of the aforementioned electrical connection ports 41 and the aforementioned detection socket 15 are electrically engaged with each other, thereby enabling the control unit to accurately detect and control the compressible force F2. It must be noted that the compressible force F2 can be the force remaining after deducting the elastic force F1; furthermore, when the plurality of elastic elements 25 are not implemented, the compressible force F2 is entirely generated by the airbag 30. All of the above fall within the scope of application of the present invention. Also, the aforementioned air source, control unit, proportional control valve, and pressure sensor are all general components and applications, and therefore are not included in the accompanying drawings.

[0031] In the next better implementation, such as Figures 1 to 5 As shown, the base 10 can be equipped with a pair of guide members 18 along the Z-axis, with the bulkhead of the top chamber 11 serving as a fixed end. The guide members 18 can be made of guide posts. Furthermore, a pressure plate 32 can be integrally connected to the bottom of the airbag 30. The pressure plate 32 is equipped with a pair of bushings or bearings that open along the Z-axis. The pressure plate 32 can pass through the pair of guide members 18 via the pair of bushings or bearings, so that when the airbag 30 inflates and moves the pressure plate 32 downwards along the Z-axis groove (e.g....),... Figure 5 As shown), the pressure plate 32 can transmit the compressible force to the object 40 by means of the guide members 18.

[0032] In further implementation, such as Figures 3 to 5 As shown, the aforementioned pressure plate 32 is provided with a pair of pressure rods 33 arranged downward along the Z-axis; in addition, the periphery (e.g., the bottom end) of the object 40 is provided with a pair of pressure-resistant ends 42 (e.g., Figure 4As shown), the plurality of pressure-resistant ends 42 have the advantage of being far from the electronic components inside the object 40, so that the pressure plate 32 can transmit the compressible force F2 through the plurality of pressure rods 33 to press the plurality of pressure-resistant ends 42, thereby further protecting the electrical connection port 41 and the internal conductive terminals or contacts of the detection socket 15 during the electrical connection process.

[0033] In the above description, by Figures 1 to 5 As can be seen, the driving direction (i.e., the Z-axis) of the compressible force F2 generated by the airbag 30 is the same as the direction of electrical connection 41 and detection socket 15 electrically connected (both are in the Z-axis); in addition, the driving direction (i.e., the Z-axis) of the compressible force F2 generated by the airbag 30 is perpendicular to the direction (i.e., the X-axis) of the driver 24 reciprocatingly driving the placement seat 20 to push outward and retract inward; this configuration helps to simplify the structural complexity of the fixture described above in this invention.

[0034] Furthermore, based on the detailed description of the aforementioned fixture, the present invention can also disclose an operation method for an object electrical testing fixture, which sequentially includes: the object 40 is suspended by the fixture, and the high-pressure air-driven airbag 30 generates a compressible force to drive the object 40, causing the electrical connection port 41 of the object 40 to be engaged with the detection socket 15, which has electrical conductivity, within the fixture. Where the compressible force F2 is greater than the elastic force F1, the object 40 can resist the compressible force F2 by bearing the elastic force F1, thereby generating a soft thrust to drive the electrical connection port 41 to engage with the detection socket 51, thus protecting the conductive terminals or contacts.

[0035] The above-described embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention.
