Description

Technology Field

[0001] The present invention relates to a jig assembly for testing a radio frequency module, and more specifically, to a jig assembly for testing a radio frequency module in which a plurality of blocks are sequentially combined in a sliding manner, thereby enabling a plurality of test stages to be performed continuously on a single jig without replacing a separate jig. Background Technology

[0002] As radio frequency (RF) modules are core components that perform communication functions, precise testing of various electrical characteristics and signal transmission performance is required before product shipment. To verify the performance of such RF modules, a widely used method involves sequentially performing multiple test processes while the module is fixed using a test jig.

[0003] Conventional jigs for RF module testing are often designed as a single structure to correspond to specific test stages. Consequently, performing different test stages required the inconvenience of separating the module under test from the jig and moving it to other test equipment or a separate jig. This resulted in problems such as a complex test process and increased working time.

[0004] Furthermore, the electrical connection between the RF module and the test jig may become unstable during repeated detachment and reattachment processes, which can lead to reduced measurement reliability and errors in defect judgment. In particular, for RF modules with high-frequency characteristics, even minute contact failures can cause signal distortion or measurement errors, making it crucial to maintain a stable connection.

[0005] Furthermore, in order to respond to various test conditions, the test configuration must be easily changeable; however, conventional jig structures had limitations in that flexible reconfiguration was difficult and scalability was restricted.

[0006] Therefore, there is an increasing demand for a new structure of RF module test jig assembly that can continuously perform multiple test stages within a single jig assembly, while also simplifying the test process, reducing testing time, and maintaining a stable electrical connection state. The problem to be solved

[0007] The present embodiment aims to provide a jig assembly for testing radio frequency modules that can continuously perform multiple test stages within a single jig assembly by configuring at least two blocks to be movable relative to each other.

[0008] The present embodiment aims to provide a jig assembly for testing radio frequency modules that can perform various tests without repeated detachment of the module to be tested by enabling selective alignment and coupling to a position corresponding to each test stage through relative movement between blocks.

[0009] The present embodiment aims to provide a radio frequency module test jig assembly capable of stably maintaining the electrical connection state between the RF module and the jig during the test process.

Specific details for implementing the invention

[0026] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are presented to sufficiently convey the concept of the present invention to those skilled in the art to which the present invention pertains. The present invention is not limited to the embodiments presented herein and may be embodied in other forms. In order to clarify the present invention, the drawings may omit the illustration of parts unrelated to the description and may slightly exaggerate the size of components to aid understanding.

[0027] FIGS. 1 and FIGS. 2 are a perspective view and a top view illustrating a jig assembly for testing a radio frequency module according to a first embodiment of the present invention, and FIGS. 3 to 5 are top views illustrating a jig assembly for testing a radio frequency module according to embodiments of the present invention.

[0028] Referring to FIGS. 1 to 5, a jig assembly for testing a radio frequency module according to the present invention may be configured to include a base plate (100), a first support plate (200), a second support plate (300), a plurality of blocks (400), and a clamping unit (500).

[0029] The base plate (100) is a structure that supports the entire jig assembly and can be provided in the shape of a rectangular flat plate. Additionally, the base plate (100) can be formed from a metal material such as aluminum alloy or steel, or a high-rigidity synthetic resin material, and can be designed to have sufficient rigidity to minimize deformation under external loads or repetitive testing processes. Furthermore, the upper surface of the base plate (100) is processed to maintain flatness, thereby ensuring precise alignment of the components installed on the upper surface.

[0030] Such a base plate (100) may include a structure such as a hole for inserting a fastening member, such as a bolt or rivet, for fixing the first support plate (200) and the second support plate (300). As described above, a plurality of holes formed on the base plate (100) may be arranged at regular intervals, and may also be formed in a slot shape so that the first support plate (200) and the second support plate (300) can be selectively placed at various positions.

[0031] The first support plate (200) is installed upright so as to protrude upward from the upper surface of the base plate (100) and can provide a reference surface that restricts the movement of the block (400) placed on the base plate (100). That is, the first support plate (200) can act as a stopper that physically blocks the block (400) from moving beyond a certain direction, and can also act as a position reference for the wireless frequency module under test.

[0032] This first support plate (200) is provided in an overall rectangular flat shape and can be fixedly installed on a base plate (100) by means of fastening members such as bolts or rivets. In addition, the height of the first support plate (200) can be set considering the height of the block (400) and the thickness of the module to be tested, and if necessary, multiple plates may be spaced apart or configured to be replaceable.

[0033] The second support plate (300) is positioned to extend in a mutually orthogonal direction from one end of the first support plate (200). More specifically, the second support plate (300) is positioned in a direction orthogonal to the length direction of the first support plate (200) while standing upright perpendicular to the upper surface of the base plate (100), so as to function as a reference structure that defines the direction of movement of the block (400).

[0034] This second support plate (300) is provided in an overall rectangular flat shape and can be fixedly installed on the base plate (100) by means of fastening members such as bolts or rivets. Additionally, the second support plate (300) can be configured to be detachable from the base plate (100), so that it can be designed to allow for position adjustment or replacement depending on the test environment. Accordingly, the first support plate (200) and the second support plate (300) are arranged in an "L" shape on the base plate (100), and a reference space in which a block (400) is placed can be formed between them. This "L" shape arrangement of the first support plate (200) and the second support plate (300) can act as a reference frame that effectively restricts the movement of the block (400) in two directions while inducing linear movement in the remaining direction (y-axis direction).

[0035] Additionally, the second support plate (300) may include a base guide rail (310) that is continuously formed along the longitudinal direction (y-axis direction) on one side where the block (400) is placed. For example, the base guide rail (310) may be provided with a groove or protrusion having a cross-section in the shape of a "T". The "T" shape of the cross-section of the base guide rail (310) can provide a structural feature that allows sliding movement in the longitudinal direction (y-axis direction) while preventing vertical and lateral deviation when combined with the block (400). Furthermore, the base guide rail (310) may be formed along the entire length of the second support plate (300) to maximize the range of movement of the block (400), and if necessary, multiple guide rails may be formed in parallel to provide a more stable guide function.

[0036] A block (400) is a plurality of components that are placed in a space formed on a base plate (100) by a first support plate (200) and a second support plate (300) to load a radio frequency module to be tested, and at least two blocks (400) may be arranged adjacent to each other. At this time, each block (400) may be arranged in a state of close contact or spaced apart at a certain interval, and the spacing may be adjusted according to the size, shape, and contact arrangement of the module to be tested. In addition, the upper surface of the block (400) may be formed flat so that the radio frequency module can be stably seated. Specifically, such a block (400) may be configured to include a base block (410) and at least one additional block (420).

[0037] The base block (410) may include a base guide projection (411) continuously formed along the longitudinal direction (y-axis direction) on one side supported by the second support plate (300), and a block guide rail (412) continuously formed along the longitudinal direction (y-axis direction) on the other side. Here, the base guide projection (411) may be provided as a projection or groove corresponding to the cross-sectional shape of the base guide rail (310). For example, the base guide projection (411) may be formed in a “T” shape or a cross-sectional shape corresponding thereto to prevent detachment in the up-down and left-right directions while inserted into the base guide rail (310).

[0038] Accordingly, the base block (410) is installed on the base plate (100) so that it can slide along the base guide rail (310) while one side is supported by the second support plate (300). Additionally, although not illustrated, the base block (410) may be coated with a low-friction material or have an internal bearing structure added to reduce friction during movement. Furthermore, the block guide rail (412) may be provided with a "T" shaped groove or protrusion in cross-section, similar to the base guide rail (310). Such a block guide rail (412) can serve as a reference structure that enables repeated attachment and detachment and movement while maintaining alignment precision when combined with an additional block.

[0039] An additional block (420) is configured to be continuously coupled and arranged to a base block (410) or another additional block, and may include a block guide projection (421) continuously formed along the longitudinal direction (y-axis direction) on one side and an additional block guide rail (422) continuously formed along the longitudinal direction (y-axis direction) on the other side. Here, the block guide projection (421) may be provided as a projection or groove corresponding to the cross-sectional shape of the block guide rail (412) of the base block (410) or the additional block guide rail (422) of the other additional block (420). At this time, the coupling of the block guide projection (421) and the additional block guide rail (422) may be designed to have a certain gap, so as to enable smooth sliding while minimizing play.

[0040] Accordingly, the additional block (420) is slidably coupled to the base block (410) or an adjacent additional block and can be positioned to move along the longitudinal direction (y-axis direction) of the second support plate (300). Additionally, since another additional block can be continuously coupled through the additional block guide rail (422) formed on the other side of the additional block (420), a plurality of additional blocks (420) can be arranged in series to form a structure that can be extended to various lengths. Due to this serial extension structure of the block (400), test configurations of various lengths can be implemented with a single jig assembly, and a flexible test environment can be established without replacing separate equipment.

[0041] In this way, the rail and protrusion coupling structure between the base block (410) and the additional block (420) forms a repeatedly connected modular structure, thereby allowing the arrangement of the blocks (400) to be flexibly adjusted according to the size or contact position of the radio frequency module under test. In particular, the modular structure of this jig assembly allows only specific blocks to be selectively replaced during maintenance, thereby providing the effect of reducing the maintenance costs of the entire system.

[0042] Meanwhile, as illustrated in FIG. 3, a plurality of blocks (400) may each include a second connector (401, 401', 401'') on one side facing the first support plate (200). Here, the second connector (401) is configured to electrically contact a radio frequency module under test to transmit and receive signals, and may be provided to protrude from one side of the block (400). At this time, the second connector (401) may be formed as a spring pin structure, thereby providing a constant elastic force upon contact, so as to maintain a stable electrical connection.

[0043] Additionally, among the plurality of additional blocks (420), the block placed at the final stage may be configured as a connector block (430). The connector block (430) may include a connector guide projection (431) that is slidably coupled to an additional block guide rail (422) on one side, and a first connector (432) for input or output of an external signal on the other side. Here, the first connector (432) is provided to be connected to a cable or external test equipment and may be internally electrically connected to the second connector (401) to form a signal transmission path. Additionally, the first connector (432) may be formed with a structure capable of impedance matching considering RF signal characteristics.

[0044] At this time, the first connector (432) functions as a connector for input or output of an external signal, and the second connector (401) can be configured to transmit a signal in the opposite direction to the first connector (432). Accordingly, a signal input from an external device may be introduced through the first connector (432) and transmitted to the test target module through the second connector (401) of each block (400), or conversely, a signal output from the test target module may be transmitted to the external device. In this process, the internal wiring may be formed with a shielded structure to minimize signal loss.

[0045] Meanwhile, referring to FIG. 4, a base auxiliary guide rail (110) and at least one auxiliary guide rail (120, 120') spaced apart from the base auxiliary guide rail (110) may be formed on the upper surface of the base plate (100) along the longitudinal direction (y-axis direction) of the second support plate (300). Here, the auxiliary guide rails (110, 120, 120') may be arranged parallel to each other to form a structure that supports the lower part of the block (400) at multiple points.

[0046] Accordingly, a base auxiliary guide projection (413) that is slidably coupled to a base auxiliary guide rail (110) may be further formed on the bottom surface of the base block (410), and an auxiliary guide projection (423, 423') that is slidably coupled to an auxiliary guide rail (120, 120') may be formed on the bottom surface of the additional block (420). At this time, each auxiliary guide projection (413, 423, 423') has a cross-section corresponding to the shape of the rail and may be lubricated to minimize friction during movement.

[0047] This auxiliary guide structure additionally supports the lower part of the block (400) along with lateral support by the second support plate (300), thereby preventing shaking or tilting that may occur during the movement of the block (400) and enabling more stable straight movement.

[0048] Additionally, the base block (410) may be configured to be connected to and disconnected from the second support plate (300), and the additional block (420) may be configured to be connected to and disconnected from the base block (410) or other additional blocks. Accordingly, the user can respond to various test environments by selectively combining or replacing the required number of blocks according to the shape or specifications of the module to be tested. Furthermore, work efficiency can be improved by rapidly implementing various test scenarios by replacing only a specific block (400).

[0049] Meanwhile, the clamping unit (500) is positioned on the base plate (100) adjacent to the end side of the additional blocks (420) and can perform the function of pressing and releasing a plurality of blocks (400) toward the second support plate (300).

[0050] Specifically, the clamping unit (500) may include a main body (510) fixedly installed on a base plate (100) and a clamping bar (520) extending from the main body (510) and configured to be adjustable in length. Here, the clamping bar (520) may be formed to be positioned parallel to the longitudinal direction of the first support plate (200) and may press or release the block (400) through forward or backward movement.

[0051] Additionally, as illustrated in FIG. 5, the base plate (100) may further include a clamping unit guide rail (130) formed along the longitudinal direction of the first support plate (200), and the main body (510) of the clamping unit (500) may include a clamping unit guide projection (511) on its bottom surface that is slidably coupled to the clamping unit guide rail (130). Accordingly, since the clamping unit (500) can move its position on the base plate (100), it can perform a clamping operation after being adjusted to an appropriate position according to the arrangement length of the block (400).

[0052] The clamping unit (500) configured in this manner can bring a plurality of blocks (400) into close contact with the second support plate (300) via the clamping bar (520) and eliminate gaps between the blocks, thereby preventing positional changes during testing. Additionally, by moving the clamping bar (520) in the opposite direction, the pressure applied to the blocks (400) is released, allowing the position of each block to be freely adjusted.

[0053] Meanwhile, FIG. 6 is a top view illustrating a state in which a radio frequency module is mounted on a jig assembly for testing a radio frequency module according to one embodiment of the present invention.

[0054] Referring to FIG. 6, the pre-drive block (B1), drive block (B2), and final block (B3) constituting the radio frequency module to be tested are each loaded onto the base block (410) and additional blocks (420, 420') so that they can be aligned in the width direction (x-axis direction) and height direction (y-axis direction) of the radio frequency module. Additionally, since the base block (410) and additional blocks (420, 420') are formed at the same height from the base plate (100), the pre-drive block (B1), drive block (B2), and final block (B3) can also be aligned in the thickness direction (z-axis direction) by being loaded onto the base block (410) and additional blocks (420, 420').

[0055] Consequently, the jig assembly for testing a radio frequency module according to the present invention can provide a rapid and precise test environment for various types of radio frequency modules through the sliding and modularized coupling structure of the block (400) and the fixing function through the clamping unit (500).

[0056] Although specific embodiments of the jig assembly for testing a radio frequency module according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0058] That is, the aforementioned embodiments should be understood as exemplary in all respects and not limiting, and the scope of the invention is defined by the claims set forth below rather than by the detailed description, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts thereof should be interpreted as being included within the scope of the invention.
