Description

Technical Field

[0001] The utility model relates to an object with electrical properties and a jig for detecting the electrical properties of the object, in particular to an object electrical property detection jig. Background Art

[0002] Electrical objects are generally those that require power to operate in order to perform their intended functions (e.g., servers). When these objects are nearly completed, they are usually subject to electrical testing to ensure the production yield of the object products.

[0003] It is known that these electrical objects generally have at least one external electrical connection port. When conducting electrical testing, the electrical connection port of the object must be connected to a testing socket provided by an electrical testing device to facilitate power-on testing.

[0004] Currently, the industry has specialized jigs for testing the electrical properties of objects. These jigs are equipped with an electrical testing assembly with a testing socket and its electrical connections. The object to be tested is typically placed in a slot of the jig by human labor or robotic arms. A servo motor drives a worm gear to generate thrust, which drives the object in the slot so that the electrical connection port engages with the testing socket, allowing the object to undergo a power-on test before shipment.

[0005] However, since electrical objects contain sophisticated electronic components, they are not suitable for withstanding excessive thrust, lest the electronic components and their structures within the objects be damaged.

[0006] In the above description, the electrical connection port and the detection socket are connected to each other by relying on the thrust generated by the servo motor driving the worm to push the object to achieve the said connection; 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 poor, which can easily cause damage to the conductive terminals or contacts, so it is urgent to improve. Utility Model Content

[0007] In view of the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an electrical testing fixture for an object, specifically using a compressible force to replace the thrust generated by the above-mentioned servo motor drive worm, and making the compressible force greater than the elastic force to protect the conductive terminals or contacts from damage during electrical connection.

[0008] To this end, the present invention provides an electrical property detection fixture for an object, comprising a base, a placement seat and an expandable and contractible airbag; the base is equipped with at least one detection socket and an electrical testing structure electrically connected to the detection socket; the placement seat is driven back and forth by a driver and is in the form of an outward-pushing and inward-retracting sliding group on the base; the placement seat provides a placement for the object to be electrically tested when it is pushed outward; and the placement seat can make at least one electrical connection port of the object exposed adjacent to the top of the detection socket when it is retracted; the airbag is arranged in the base and connected to an air source via an air inlet, the air source can fill the airbag to expand and generate a compressible force, and the airbag transmits the compressible force to drive at least one of the electrical connection ports of the object and the detection socket to electrically engage with each other.

[0009] In a further embodiment, a plurality of elastic elements are respectively disposed on both sides of the placement seat, and the object resists the compressible force by virtue of an elastic force generated by the plurality of elastic elements, and the compressible force is greater than the elastic force.

[0010] In a further embodiment, the placement seat is slidably mounted on the base via a slide, and the driver is configured on the base and transmission-connected to the slide.

[0011] In a further embodiment, a plurality of elastic elements are disposed on both sides of the placement seat and between the slide seat. The object resists the compressible force by virtue of an elastic force generated by the plurality of elastic elements, and the compressible force is greater than the elastic force. Furthermore, the air source is a high-pressure air source, and the air source is equipped with a proportional control valve capable of sensing the pressure value of the high-pressure air. 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 engaged with each other. A control unit is electrically connected between the proportional control valve and the pressure sensor to detect and control the compressible force.

[0012] In a further embodiment, the plurality of elastic elements are coil springs, and columns for guiding and holding the coil springs are arranged between the two sides of the placement seat and the slide seat.

[0013] In a further embodiment, a pair of guide members are disposed in the base, and the airbag is integrally connected to a pressure plate. The pressure plate is guided by the pair of guide members to transmit the compressible force to drive the object.

[0014] In a further embodiment, the pressure plate is configured with a plurality of pairs of pressure rods, and a plurality of pairs of pressure-resistant ends are provided around the object. The pressure plate transmits the compressible force to the object by pushing the plurality of pressure-resistant ends via the plurality of pressure rods.

[0015] In the above embodiment, the driving direction of the airbag to generate the compressible force is the same as the direction in which the electrical connection port and the detection socket can be electrically engaged with each other. In addition, the driving direction of the airbag to generate the compressible force is perpendicular to the direction in which the driver reciprocates to push and retract the placement seat.

[0016] 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 pressure value of the high-pressure air. 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 engaged with each other.

DETAILED DESCRIPTION

[0025] First, please refer to Figures 1 to 3 As shown, the present invention discloses an electrical property detection fixture for an object, which includes a base 10, a placement seat 20 and an expandable airbag 30. The base 10 can be assembled from a metal frame plate, so that the base 10 forms a top compartment 11, a middle compartment 12 and a bottom compartment 13 that are connected to each other as a whole. Among them, the top compartment 11 is used to configure the airbag 30, the middle compartment 12 is used to configure the placement seat 20, and the bottom compartment 13 is connected to a plate 14 at the bottom of the base 10, and is used to configure at least one detection socket 15 and an electrical measurement structure 16 electrically connected to the detection socket 15. The detection socket 15 has many conductive terminals or contacts that can be energized; the electrical measurement structure 16 includes electronic components that provide adaptive current to the detection socket 15, and the electrical measurement structure 16 can also include a pressure sensor.

[0026] like Figure 1 As shown, the placement seat 20 is formed with a groove frame 21 and vertical walls 22 on both sides of the groove frame. The bottom of the groove frame 21 is formed with a frame hole 211, so that the detection socket 15 of the bottom cabin 13 can be exposed to the middle cabin 12 through the frame hole 211. Figure 2 As shown, the placement seat 20 can provide an object 40 to be tested for electrical properties by means of the slot frame 21. The object 40 can be a server or other object that needs to be powered on to perform a predetermined function. The bottom of the object 40 has at least one electrical connection port 41 (such as Figure 4 As shown in FIG. 4 , the electrical connection port 41 also has a plurality of conductive terminals or contacts that can be electrically conductive.

[0027] In a preferred embodiment, Figure 1 and Figure 2It is revealed that the placement seat 20 can be slidably assembled to the center cabin 12 of the base 10 via a slide 23. Furthermore, the slide 23 is surrounded by two side walls 231 and a connecting wall 232 to form a hollow quadrilateral frame. The two sides of the slide 23 are respectively equipped with sliding components such as slide rails by means of the two side walls 231. The two sides of the center cabin 12 are respectively pivotally provided with a plurality of free rotors 121 to guide the two side walls 231 of the slide 23. Furthermore, a tongue 233 is formed on one side of the connecting wall 232. The side wall 17 of the base 10 (such as Figure 2 As shown) is provided with a driver 24, which can be made of a pneumatic cylinder. The slide 23 provides a cylinder rod 241 of the driver 24 with a transmission connection by means of the tongue 233, so that the driver 24 can reciprocate and drive the slide 23. Figure 3 and Figure 4 The X-axis shown in the figure is moved outward and inward. Figure 1 and Figure 3 The state in which the placement seat 20 is extended and the object 40 is not placed is disclosed. Figure 2 The object 40 is placed on the placement seat 20 when it is extended. Figure 4 As shown, it is further revealed that when the placement seat 20 is retracted, the electrical connection port 41 of the object 40 can be exposed adjacent to the top of the detection seat 15 along the Z-axis.

[0028] In another preferred embodiment, Figure 1 and Figure 2 It is revealed that a plurality of elastic elements 25 are respectively disposed between the vertical walls 22 on both sides of the placement seat 20 and the side walls 231 on both sides of the slide 23; furthermore, the plurality of elastic elements 25 can be made of coil springs, and a plurality of columns 251 for guiding the coil springs are disposed between the vertical walls 22 on both sides of the placement seat 20 and the side walls 231 on both sides of the slide 23; according to this configuration, the plurality of elastic elements 25 can provide an upward elastic force F1 along the X-axis (such as Figure 5 as shown) to the placement seat 20 and the object 40 placed on the placement seat 20.

[0029] Please refer back to Figure 3 and Figure 4 As shown, the airbag 30 is disposed in the top compartment 11 of the base 10; the airbag 30 can be made of a soft gas-filled capsule made of rubber or other materials, and has an air inlet 31 for connecting to an air source; the air source can be generated by high-pressure air provided by an air supply line, and the air source is equipped with a proportional control valve (not shown) that can sense the pressure value of the high-pressure air. Figure 5As shown, a high-pressure air source fills the airbag 30 to expand, driving the airbag to generate a compressible force F2 that drives the electrical connection port 41 of the object 40 and the detection socket 51 to electrically engage with each other. The elastic force F1 is used to resist the compressible force F2, and the compressible force F2 is greater than the elastic force F1, so that the electrical connection port 41 of the object 40 can engage with the detection socket 51 in a flexible manner under spring pressure, thereby protecting the electrical connection port 41 and the conductive terminals or contacts within the detection socket 15 from damage.

[0030] Furthermore, the present invention can also rely on a control unit to electrically connect the above-mentioned proportional control valve and the pressure sensor, wherein the pressure sensor is used to sense the pressure value when at least one of the electrical connection ports 41 and the detection socket 15 are electrically connected to each other, and then accurately detect and control the compressible force F2 through the control unit. It must be noted that the compressible force F2 can be the remaining force after offsetting the elastic force F1; in addition, when the plurality of elastic elements 25 are not configured, the compressible force F2 is entirely generated by the airbag 30. The above are all within the scope of application of the present invention. In addition, the above-mentioned air source, control unit, proportional control valve and pressure sensor are all general components of the assembly and application, so they are not attached to the drawings.

[0031] In a second preferred embodiment, if Figures 1 to 5 As shown, the base 10 can be configured with a pair of guide members 18 along the Z-axis by using the bulkhead of the top cabin 11 as a fixed end. The guide members 18 can be made of guide pillars. In addition, the bottom of the airbag 30 can be integrally connected to a pressure plate 32. The pressure plate 32 is configured with a pair of shaft sleeves or bearings open along the Z-axis. The pressure plate 32 can pass through the pair of guide members 18 by using the pair of shaft sleeves or bearings, so that when the airbag 30 expands and drives the pressure plate 32 to move down the Z-axis groove (as shown in FIG. Figure 5 As shown), the pressing plate 32 can transmit the compressible force to the object 40 by means of the guide of the pair of guide members 18.

[0032] In a further implementation, if Figures 3 to 5 As shown, the pressure plate 32 is provided with a plurality of pairs of pressure rods 33 downwardly along the Z axis; in addition, the periphery (eg, bottom end) of the object 40 provides a plurality of pairs of pressure-resistant end portions 42 (eg, Figure 4 ), the plurality of pressure-resistant ends 42 have the advantage of being away from the electronic components contained in the object 40, so that the pressure plate 32 can transmit the compressible force F2 through the plurality of pressure rods 33 to push the plurality of pressure-resistant ends 42, and can further protect the electrical connection port 41 and the conductive terminals or contacts inside the detection socket 15 during the electrical connection process.

[0033] In the above, Figures 1 to 5 It should not be difficult to find that the driving direction (i.e., the Z-axis direction) in which the airbag 30 generates the compressible force F2 is the same as the direction in which the electrical connection port 41 and the detection socket 15 are electrically connected (both in the Z-axis direction); in addition, the driving direction (i.e., the Z-axis direction) in which the airbag 30 generates the compressible force F2 is perpendicular to the direction (i.e., the X-axis direction) in which the driver 24 reciprocates to drive the placement seat 20 outward and inward; this configuration helps to simplify the structural complexity of the above-mentioned fixture of the present invention.

[0034] The above-described embodiments merely express preferred implementation methods of the present invention, but should not be construed as limiting the patent scope of the present invention.
