Description

Pressure measuring mechanism

Technical Field

The present invention relates to a pressure measurement mechanism, and more particularly to a pressure measurement mechanism for measuring impedance.

Background

The traditional impedance measuring mechanism presses the element to be measured to the carrier through the pressing piece, so that the pin of the element to be measured can be tightly contacted with the electrode contact of the carrier, and a back-end system is provided for testing. In addition, the impedance measuring mechanism can be used for independently testing various types of elements to be tested. When the impedance measuring mechanism is changed to test another element to be tested with a different model, in order to allow the pressing member to effectively press the element to be tested with the different model, a user needs to change the configuration position of the carrier table, so that the element to be tested moves to an effective position below the pressing member.

However, since the carrier of the impedance measuring mechanism includes many complex components stacked on each other, in order to change the configuration orientation of the carrier, a user must take out the components in the carrier in sequence, rotate the components in sequence, and then put the components back into the carrier in sequence, which is time-consuming and labor-consuming, and may cause damage to the device to be tested due to incorrect installation.

It is clear that the above-mentioned techniques still have inconveniences and drawbacks, and need further improvement. Therefore, how to effectively find a solution to overcome the above inconvenience and drawback is one of the important research and development issues, and is also an urgent need for improvement in the related art.

Detailed Description

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in the embodiments of the present invention, these practical details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner.

Unless defined otherwise, all words (including technical and scientific terms) used herein have their ordinary meaning as is understood by those skilled in the art. Furthermore, the definitions of the above words and phrases in general dictionary should be read in the content of the present specification to be consistent with the meaning and meaning of the relevant fields of the present invention. Unless specifically defined otherwise, these terms are not to be interpreted in an idealized or overly formal sense.

Fig. 1 is a partially exploded view of a pressure measurement mechanism 10 according to an embodiment of the present invention. Fig. 2 is a partial top view of the stage 100 of the pressure measuring mechanism 10 of fig. 1. Fig. 3 is a schematic view of the pressure measuring mechanism 10 of fig. 1 and an enlarged view of a part M1 thereof. As shown in fig. 1 to 3, the pressure measuring mechanism 10 includes a carrier 100, a pressing device 200, and an electrode 300. The electrode portion 300 is located in the stage 100, and the electrode portion 300 includes a first contact 310 (e.g., a positive electrode) and a second contact 320 (e.g., a negative electrode) with opposite polarities. The carrier 100 includes a receiving cavity 101, a first fixed area 170 and a second fixed area 180. A plurality of openings 151 are arranged in the receiving groove 101. Each of the openings 151 simultaneously exposes the first contact 310 and the second contact 320, and the sizes of the openings 151 are different from each other. Each opening 151 receives a different size of dut 400 (fig. 3). For example, the device under test 400 is a passive device (e.g., inductor L, capacitor C, resistor R), and the passive device is manufactured into different types of devices according to the function or characteristic, such as 0402, 0603, 0805, 1206 (unit: inch). The first fixing area 170 and the second fixing area 180 are respectively located on different sides of the accommodating groove 101. The pressing device 200 is selectively locked on the first fixing area 170 or the second fixing area 180, so that the pressing device 200 can move to a position right above the device under test 400 to effectively press down the device under test 400 in one of the openings 151, and thus, the pins (not shown) of the device under test 400 can respectively and tightly contact the first contact 310 and the second contact 320 in the opening 151.

Specifically, the carrier 100 further includes a base 110 and a carrier 120. The base 110 has a crevasse 111. Carrier 120 is removably inserted into base 110, and a portion of carrier 120 is exposed from breach 111 of base 110. The accommodating cavity 101, the first fixing area 170 and the second fixing area 180 are all located on the carrier 120 at the same time and exposed from the opening 111 of the base 110.

The receiving groove 101 is circular, and the openings 151 surround the center of the receiving groove 101. These openings 151 are, for example, rectangular, and the long axis directions (e.g., X or Y axes) of the two openings 151 intersect or even are orthogonal to each other (fig. 2). However, the present invention is not limited thereto.

In the embodiment, the first fixed area 170 and the second fixed area 180 are respectively located at two adjacent sides of the accommodating groove 101, but not at the same side of the accommodating groove 101. For example, the first fixing region 170 includes a plurality (e.g., 2) of first fixing holes 171, and the second fixing region 180 includes a plurality (e.g., 2) of second fixing holes 181. The first fixing holes 171 and the second fixing holes 181 are respectively located at two adjacent sides of the receiving cavity 101, in other words, imaginary connecting lines between the first fixing holes 171 and the imaginary connecting lines between the second fixing holes 181 intersect with each other, or even are orthogonal to each other. The pressing device 200 is locked into the first fixing hole 171 through a plurality (e.g., 2) of fixing bolts 290, so that the pressing device 200 can be fixed on the first fixing area 170 and located at one side of the accommodating groove 101 (fig. 3). However, the present invention is not limited thereto.

Fig. 4 is another schematic view of the pressure measuring mechanism 10 of the present embodiment and an enlarged view of a part M2 thereof. As shown in fig. 1 and fig. 4, when the user changes the to-be-tested device 401 to be placed in the opening 151, the user only needs to disengage the fixing bolt 290 from the first fixing hole 171 and lock the fixing bolt into the second fixing hole 181, so that the pressing device 200 is fixed to the adjacent side of the accommodating slot 101 from the original side of the accommodating slot 101, and can further effectively press the to-be-tested device 401 in the opening 151.

More specifically, as shown in fig. 1 and 4, the pressing device 200 includes a base 210, a bracket 240 and a pressing rod 280. The base 210 is locked to the carrier 100 by a fixing bolt 290. The bracket 240 is fixedly disposed on the top surface 211 of the base 210. The down-pressure rod 280 is disposed on the bracket 240 in a liftable manner, and is used for moving down to the dut 400 in the opening 151. More specifically, the bracket 240 is in a zigzag shape, the bracket 240 has a first end 241 and a second end 242 opposite to each other, the first end 241 and the second end 242 have a height difference, the first end 241 of the bracket 240 is fixed on the top surface 211 of the base 210, and the second end 242 of the bracket 240 is located above the accommodating groove 101 and bears the push-down lever 280.

More specifically, the hold-down device 200 further includes a plurality (e.g., 2) of first slots 220. The first slits 220 are respectively opened on the base 210, and the long axis directions (such as the X axis) of the first slits 220 are coaxial with each other. Each securing latch 290 extends through one of the first slots 220 and is latchingly retained in one of the first securing holes 171. For example, each fixing bolt 290 is a bolt, and each of the first fixing hole 171 and the second fixing hole 181 is a screw hole.

Thus, before the pressing device 200 is assembled to one side of the receiving cavity 101 through the fixing bolt 290, the pressing device 200 can slide along the first slot 220 to adjust the corresponding position of the pressing device 200 and the receiving cavity 101. Similarly, before the pressing device 200 is assembled to the adjacent side of the receiving groove 101, the pressing device 200 can also slide along the first slot 220 to adjust the corresponding position of the pressing device 200 and the receiving groove 101.

Further, the bottom surface 212 of the base 210 has a guiding groove 230. The long axis direction of the guide groove 230 is parallel to the long axis direction (e.g., X axis) of the first slit 220. The carrier 120 of the carrier 100 has a plurality (e.g., 2) of first bumps 130 and a plurality (e.g., 2) of second bumps 140. The first bumps 130 and the second bumps 140 are respectively located on two adjacent sides of the receiving groove 101. In other words, imaginary connecting lines between the first bumps 130 and the second bumps 140 intersect with each other, or even are orthogonal to each other. The first tab 130 is slidably located within the guide groove 230. Thus, when the pressing device 200 slides along the first slot 220, the pressing device 200 can smoothly slide along the first slot 220 by the cooperation of the first protrusion 130 in the guiding groove 230. Similarly, when the pressing device 200 is engaged in the guiding groove 230 through the second protrusion 140, the pressing device 200 can smoothly slide along the first slot 220 on the adjacent side of the receiving groove 101.

However, the present invention is not limited thereto, and in other embodiments, the design (not shown) of the first slot 220 may be changed to allow the extending direction (e.g. Y axis) of the first slot 220 to pass through the receiving groove 101, so that the pressing device 200 can slide along the first slot 220 at one side of the receiving groove 101, so as to adjust the distance between the pressing device 200 and the receiving groove 101.

Fig. 5 is an exploded view of stage 100 of pressure measuring mechanism 10 according to the present embodiment. As shown in fig. 1 and 5, the pressing device 200 further includes a pushing member 250, a locking member 260 and a spring element 270. The pushing member 250 is pivoted to the bracket 240 via a pivot 253, so that the pushing member 250 can pivot relative to the bracket 240. The pusher 250 has a second slot 254. The long axis direction (e.g., Y axis) of the second slit 254 is orthogonal to the long axis direction (e.g., X axis) of the first slit 220. The second slot 254 is opened at the front end 251 of the pushing member 250 for the end of the lower pressing rod 280 opposite to the receiving groove 101 to pass through. The depression bar 280 can be moved along the second slot 254 to adjust the degree of tilt of the depression bar 280. The locking member 260 is fixedly disposed at an end of the lower pressing rod 280 opposite to the accommodating groove 101, and limits the lower pressing rod 280 on the pushing member 250. The second end 242 of the bracket 240 has an elongated slot 243. The spring element 270 is disposed in the slot 243, sleeved on the down-pressing rod 280, and abutted against the down-pressing rod 280 and the stopper 281 in the slot 243. The long axis direction (e.g., Z axis) of the elongated slot 243 is orthogonal to the long axis direction (e.g., X axis) of the first slit 220 and the long axis direction (e.g., Y axis) of the second slit 254, respectively.

Thus, when a user pushes the rear end 252 of the pushing member 250 towards the bracket 240, such that the front end 251 of the pushing member 250 pulls the pressing rod 280 upwards, and the pressing rod 280 is pulled away from the receiving groove 101, the spring element 270 is compressed and stores a restoring force. Conversely, when the user releases the rear end 252 of the push member 250, the restoring force of the spring member 270 pushes the depression bar 280 back into the receiving groove 101.

As shown in fig. 2 and 5, the electrode portion 300 further includes an insulating ring 340, and the first contact 310 includes a metal pillar 311. The second contact 320 includes a conductive ring 321 and a conductive plate 330. The insulating ring 340 surrounds the pillar 311 and is directly located between the pillar 311 and the conductive ring 321. The conductive ring 321 surrounds the insulating ring 340 and the metal center pillar 311. The conductive plate 330 includes a metal plate 331 and a through opening 332, wherein the metal plate 331 covers a surface of the conductive ring 321 and is electrically connected to the conductive ring 321. The through hole 332 is formed on the metal sheet 331, and the metal pillar 311 passes through the through hole 332.

The carrier 100 further includes an alignment pad 150 and a top cover 160. The alignment pad 150 covers the conductive plate 330, the insulating ring 340 and the first contact 310. The openings 151 are opened on the alignment pad 150, and each opening 151 exposes a portion of the conductive plate 330, a portion of the insulating ring 340, and a portion of the first contact 310. The upper cover 160 fixes the alignment pad 150 on the conductive plate 330, and the upper cover 160 includes a through hole 161 that simultaneously exposes the openings 151. The alignment pad 150 is directly sandwiched between the carrier 120 and the metal plate 331 (fig. 1). The metal sheet 331 is directly sandwiched between the conductive ring 321 and the alignment pad 150. The carrier 120 has an opening 121. The opening 121 exposes the alignment pad 150 and the conductive ring 321. The upper cover 160 covers the opening 121 of the carrier 120. In addition, one surface of the conductive ring 321 has the guide pillars 322, and the top cover 160, the carrier 120, the alignment pad 150, and the conductive sheet 330 are sequentially overlapped to the conductive ring 321 and then sequentially penetrated by the guide pillars 322.

Finally, the above-described embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the appended claims.
