Description

Technical Field

[0001] The present invention relates to a lead relay assembly.

Background Art

[0002] A lead relay is used for performing various tests and measurements by connecting and disconnecting circuits on a test interface board in semiconductor testing, and is an indispensable passive element. For example, a lead relay can be used to connect a specific pin of an IC to an external measurement device such as a semiconductor test system, an automated test equipment (ATE), an oscilloscope, or a multimeter to measure the function, radio frequency performance, voltage, or current of the IC. Exactly because of its fast switching speed, low contact resistance, and high-precision control, it plays a very important role in semiconductor testing.

[0003] However, in actual use, the lead relay still needs to meet different operating requirements according to the usage environment. However, the existing lead relay cannot provide a complete adaptation solution structurally.

Means for Solving the Problems

[0005] The reed relay assembly of this invention includes a relay body and an adapter. The relay body has a plurality of first pins and a plurality of contact protrusions, each extending and protruding from the bottom surface of the relay body. The adapter is detachably assembled to the relay body. The adapter has a platform and a plurality of second pins, the platform having opposing first and second surfaces, the second pins extending and protruding from the second surface. The platform has a plurality of housing notches exposed on the first surface, and these second pins expose a plurality of conversion holes on the first surface, the first pins are inserted into the corresponding conversion holes, and the contact protrusions are inserted into the corresponding housing notches, thereby bringing the bottom surface into contact with the first surface.

[0006] In one embodiment of the present invention, the platform described above is a rectangular plate, and the accommodation notches are located on the four side edges of the rectangular plate and adjacent to the first surface.

[0007] In one embodiment of the present invention, the relay body described above is a multi-channel reed relay, and some of the second pins penetrate the platform from the first surface to the second surface and are located at multiple corners of the platform.

[0008] In one embodiment of the present invention, the platform described above further has a plurality of relief cutouts, each located at a corner where a second pin is located.

[0009] In one embodiment of the present invention, the second pin located at the corner includes a head step, a middle step, and a tail step, the middle step being connected between the head step and the tail step, the middle step being drilled into and fitted into the platform, and the head step being located in a relief notch.

[0010] In one embodiment of the present invention, the platform described above has fitting holes at the corners, the middle section is fitted into the fitting holes, and the outer diameter of the top section is larger than the inner diameter of the fitting holes, thereby retaining the top section in a relief cutout.

[0011] In one embodiment of the present invention, at least one second pin that is not located at a corner has its head and middle sections fitted into fitting holes in the platform, respectively. [Effects of the Invention]

[0012] As described above, the reed relay assembly, consisting of a relay body and an adapter, allows the multiple first pins of the relay body to be smoothly inserted into the second pins of the adapter, enabling the relay body to be connected to other devices (e.g., circuit boards) via the adapter. In addition, the multiple contact protrusions of the relay body can be further inserted into the housing notches of the adapter for housing. In this way, the characteristic of the contact protrusions protruding high relative to the relay body can be eliminated by the presence of the housing notches. [Brief explanation of the drawing]

[Figure 5B] This is a schematic diagram of an adapter according to another embodiment of the present invention. [Modes for carrying out the invention]

[0014] Figure 1 is an exploded schematic diagram of a reed relay assembly according to one embodiment of the present invention. Figure 2 is a side view of the reed relay assembly of Figure 1 in use. Referring to Figures 1 and 2 together, in this embodiment, the reed relay assembly 100 includes a relay body 120 and an adapter 110. The relay body 120 has a plurality of first pins 123 and a plurality of contact protrusions 122a, each extending and protruding from the bottom surface 122b of the relay body 120. The adapter 110 is detachably assembled to the relay body 120. The adapter 110 has a platform 111 and a plurality of second pins 112, the platform 111 having opposing first surfaces S1 and second surfaces S2, and the second pins 112 extending and protruding from the second surface S2. The platform 111 has a plurality of housing notches 111a exposed on the first surface S1, and these second pins 112 expose a plurality of conversion holes 112d on the first surface S1, the first pins 123 are inserted into the corresponding conversion holes 112d, and the contact protrusions 122a are inserted into the corresponding housing notches 111a, thereby bringing the bottom surface 122b into contact with the first surface S1.

[0015] As shown in Figures 1 and 2, the relay body 120 of this embodiment includes a metal shell 121, a plastic base 122, and the aforementioned plurality of first pins 123. Here, since the relay body 120 is a multi-channel reed relay, it can accommodate a plurality of reed relays after the metal shell 121 and the plastic base 122 are coupled, and therefore has a plurality of first pins 123 protruding from the base 122b. Since the structural features of reed relays are known, the plurality of reed relay structures inside the metal shell 121 are omitted. In other embodiments not shown, the metal shell 121 of this embodiment may be replaced with another material, for example, a plastic shell.

[0016] Figure 2 shows a side view of the relay body 120 when it is inserted into an external device via the adapter 110. Here, the external device is, for example, a circuit board 15, which is the relevant circuit board of the external equipment for semiconductor testing described above. Multiple first pins 123 and multiple second pins 112 allow the circuit board 15 and the reed relay to establish a smooth electrical connection. More importantly, as shown in Figure 2, the housing notch 111a accommodates the corresponding contact protrusion 122a, so that the relay body 120, adapter 110, and circuit board 15 form a tight structure. Here, the bottom surface 122b abuts against the first surface S1, and the second surface S2 abuts against the circuit board 15. In this way, the height of the contact protrusion 122a is considered to be absorbed for the relay body 120 and adapter 110 after coupling, so that the relay body 120 and adapter 110 do not have to smoothly lower their overall height after coupling due to the presence of the contact protrusion 122a.

[0017] Figures 3 and 4 are schematic diagrams of the partial structure of the reed relay adapter, respectively. Referring to Figures 1, 3, and 4 together, in this embodiment the platform 111 is a rectangular plate, and the housing notches 111a are located on the four side edges of the rectangular plate and adjacent to the first surface S1. Furthermore, the platform 111 has a plurality of fitting holes 111b, and the housing notches 111a and the fitting holes 111b are different from each other and substantially offset from each other so that the second pin 112 does not collide with the second pin when it is drilled into these fitting holes 111b and fitted, and the resistance projection 122a does not collide with the second pin when it is inserted into the housing notches 111a. Unlike the case where the receiving notches 111a are located on the four side edges of a square plate, in this embodiment, some (two) second pins 112 are drilled in the center of the platform 111 from the first surface S1 to the second surface S2, while the other four second pins 112 are drilled in the platform 111 from the first surface S1 to the second surface S2 and are located at the four corners of the platform 111. Here, the platform 111 has a plurality (six) of fitting holes 111b corresponding to the number of second pins 112. The number of second pins 112 and fitting holes 111b is not limited herein and can be adjusted according to relevant standards and requirements.

[0018] Furthermore, it should be noted that the second pin 112 includes a head section 112a, a middle section 112b, and a tail section 112c, with the middle section 112b connected between the head section 112a and the tail section 112c. The head section 112a and the middle section 112b have the aforementioned conversion hole 112d, and are butt-connected to the first pin 123. In this embodiment, these second pins 112 are fitted into the fitting hole 111b by the head section 112a and the middle section 112b. In other words, the fitting hole 111b has an internal bore structure that can interfere with and accommodate the head section 112a and the middle section 112b.

[0019] FIG. 5A is a schematic diagram of a platform according to another embodiment of the present invention. FIG. 5B is a schematic diagram of an adapter according to another embodiment of the present invention. Referring to FIGS. 5A and 5B simultaneously, the difference from the foregoing embodiment is that the platform 211 of this embodiment further has a plurality of relief cutouts 211a, each of which is located at the corner where the second pin 112 is located. As shown in the figure, in the square plate of this embodiment, the relief cutouts 211a are located at the four corners where the second pins 112 are located, which corresponds to the second pins 112 at these locations being inserted into the fitting holes 211b through the middle sections 112b. Comparing FIG. 4 and FIG. 5A, for the second pin 112 of this embodiment, the outer diameter D1 of the head section 112a is larger than the inner diameter D3 of the fitting hole 211b, thereby retaining the head section 112a in the relief cutout 211a.

[0020] As shown in FIG. 5B, after the platform 211 is manufactured by plastic injection molding, in order to drill the second pin 112 into it from the first surface S1 towards the second surface S2, for the corners of the platform 211, there is a risk that the preliminary width (the relative distance from the fitting hole 211b to the side edge of the square plate) is insufficient and the structural strength is insufficient to support the aforementioned drilling operation. That is, due to the aforementioned risk, the platform 211 faces a situation of damage when drilling the second pin 112. Based on this, in this embodiment, further, relief cutouts 211a are formed at the corner portions, and the second pin 112 is inserted into the fitting hole 211b only through its middle section 112b, and the head section 112a is made to stay in the relief cutout 211a, thereby avoiding the aforementioned risk.

[0021] As described above, in the above-described embodiment of the present invention, the lead relay assembly composed of the relay body and the adapter can smoothly insert a plurality of first pins of the relay body into the second pins of the adapter, and the relay body can be connected to other devices (for example, a circuit board) by the adapter. In addition, a plurality of abutting convex portions of the relay body can be further inserted into and accommodated in the accommodation notch of the adapter. In this way, the feature that the abutting convex portion protrudes highly with respect to the relay body can be eliminated by the presence of the accommodation notch.

[0022] Furthermore, for the adapter, when the platform drills the second pins, especially when drilling the corner fitting holes, in order to avoid damage to the platform due to insufficient structural strength, a relief notch is formed at the corner of the platform. Thereby, the second pin at this location is inserted into the fitting hole through structural interference only in the middle section, and the head section is left in the relief notch, thereby avoiding the risk of damage to the platform during the above-mentioned drilling.

[0023] The lead relay assembly of the present invention is used in the field of relays.
