Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and specifically relates to a composite structure combining a multi-density rectangular connector and a PogoPin. Background Technology

[0002] In the field of semiconductor testing, with the continuous increase in chip integration, the demand for high-density and high-precision electrical connections is growing. Traditional connector structures generally suffer from poor connection stability when dealing with multi-pin chip testing. Traditional PogoPin connectors often use a simple straight hole mounting method, and the probes lack effective constraints in the axial and radial directions. During testing, they are prone to displacement due to vibration or uneven force, resulting in poor contact or signal interference, which affects the test accuracy. Utility Model Content

[0003] This utility model addresses the problems of existing technologies by providing a composite structure that combines a multi-density rectangular connector with a PogoPin. The specific technical solution is as follows:

[0004] A composite structure combining a multi-density rectangular connector and a PogoPin, comprising a base connector, the base connector including:

[0005] A modular base includes a detachably connected base and a cover. The base has an installation hole, and the cover has a limiting hole. The installation hole and the limiting hole communicate and cooperate to form an installation channel.

[0006] And the probe, in the installed state, is confined within the installation channel.

[0007] As a further technical solution of this utility model, both the mounting hole and the limiting hole are stepped structures, wherein:

[0008] The mounting hole includes a wide diameter section and a narrow diameter section, wherein the diameter of the narrow diameter section is smaller than the diameter of the wide diameter section.

[0009] The limiting hole includes a wide diameter section two and a narrow diameter section two, wherein the diameter of the narrow diameter section two is smaller than the diameter of the wide diameter section two;

[0010] In the installed state, the second wide-diameter section and the first wide-diameter section are adjacent to each other, forming a stepped cavity that is wide in the middle and narrow at both ends.

[0011] As a further technical solution of this utility model, the probe includes a needle sleeve and a needle head. The needle sleeve includes a base segment and an extension segment that are successively narrowed in one direction. In the installed state, the needle sleeve is confined in a stepped cavity formed by the second wide-diameter segment and the first wide-diameter segment. The extension segment penetrates the first narrow-diameter segment and is exposed.

[0012] As a further technical solution of this utility model, the base segment has an outer ring, which fits against the inner end wall of the stepped cavity.

[0013] As a further technical solution of this utility model, the combined substrate is provided with a plurality of installation channels arranged in a multi-row, multi-column rectangular distribution structure.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) In this application, a detachable and modular base design is used;

[0016] The basic connector's modular base features a detachable base and cover structure, which together form an installation channel. Disassembly allows for quick probe replacement, resolving the issue of traditional connectors' inability to adapt to different pin structures. This significantly improves test compatibility and maintenance efficiency. The modular design reduces overall replacement costs due to pin shape differences, meeting the needs of various testing scenarios.

[0017] (2) In this application, the stepped installation channel is matched with the probe;

[0018] The mounting holes and limiting holes adopt a stepped structure, forming a cavity that is "wide in the middle and narrow at both ends". The probe's sheath is designed with a base section, an extension section, and a docking section that decrease in diameter in sequence, and fits against the inner wall of the stepped cavity through a ring.

[0019] Axial restriction: Wide diameter section one and wide diameter section two work together to restrict the axial movement of the needle sleeve from both ends, preventing the probe from becoming loose during testing.

[0020] Radial constraint: The ring body fills the cavity gap, combined with the narrow diameter section of the aperture constraint, to prevent the probe from radially deviating, ensuring the stability of the electrical connection and the accuracy of the test.

[0021] By combining the stepped structure with the probe diameter reduction design, a four-dimensional constraint of "biaxial + biradial" is achieved, which significantly improves the connection reliability.

[0022] (3) In this application, high-density integration and standardized layout;

[0023] The modular substrate features mounting channels arranged in a multi-row, multi-column rectangular pattern, enabling the integration of a large number of probes within a limited space to form a high-density test interface. Compared to traditional discrete connectors, this solution can significantly improve the efficiency and density of chip testing, adapting to the multi-pin testing requirements of advanced process chips.

[0034] Figure 1 In this embodiment, the basic connector 2 and the adapter 3 cooperate to form a connector structure, establishing an electrical connection between the terminal component 4 and the test base plate 1, thereby enabling high-density chip testing. This embodiment only makes further improvements to the basic connector 2, while the test base plate 1, adapter 3 and terminal component 4 are all existing technologies.

[0035] Figure 2In the composite structure combining the multi-density rectangular connector and PogoPin, there is a base connector 2. The base connector 2 includes a combined base 21 and a probe 22. The combined base 21 has several mounting channels arranged in a multi-row, multi-column rectangular distribution structure. The probe 22 is confined within the mounting channels, and the two ends of the probe 22 are exposed to facilitate docking.

[0036] Figure 3 In the middle, the combined base 21 includes a detachably connected base 211 and a cover 212. That is, when disassembling, the mounting channel is disassembled and the probe 22 can be removed, which facilitates the replacement of the probe 22 to adapt to different pin structures.

[0037] The mounting channel includes a mounting hole 2111 and a limiting hole 2121. The mounting hole 2111 is opened in the base 211, and the limiting hole 2121 is opened in the cover 212. In the installed state, the mounting hole 2111 and the limiting hole 2121 are connected and cooperate to form the mounting channel for limiting the probe 22.

[0038] Figure 4 and Figure 5 In the mounting hole 2111 and the limiting hole 2121, both are stepped structures. The mounting hole 2111 includes a wide diameter section 2111a and a narrow diameter section 2111b, the diameter of which is smaller than that of the wide diameter section 2111a. The limiting hole 2121 includes a wide diameter section 2121a and a narrow diameter section 2121b, the diameter of which is smaller than that of the wide diameter section 2121a. In the installed state, the wide diameter section 2121a and the wide diameter section 2111a are adjacent to each other, forming a stepped cavity that is wide in the middle and narrow at both ends, so as to restrict the probe 22 installed therein.

[0039] Figure 6In the probe 22, a needle sleeve 221 and a needle tip 222 are included. The needle sleeve 221 includes a base segment 2211, an extension segment 2212, and a docking segment 2213 that decrease in diameter in one direction. That is, the diameters of the base segment 2211, the extension segment 2212, and the docking segment 2213 decrease sequentially. The base segment 2211 has an annular body 2214 outside. In the installed state, the needle sleeve 221 is confined within the stepped cavity formed by the second wide-diameter segment 2121a and the first wide-diameter segment 2111a. The docking segment 2213 penetrates through the second narrow-diameter segment 2121b and is exposed. The extension segment 2212 penetrates through the first narrow-diameter segment 2111b and is exposed. The annular body 2214 fits against the stepped cavity. The inner end wall of the cavity forms a radial constraint; the position of the needle sleeve 221 can be restricted from both ends by the cooperation of the second wide diameter section 2121a and the first wide diameter section 2111a, thereby restricting the axial movement space of the needle sleeve 221 and ensuring that the needle sleeve 221 does not move axially in the working state. The ring body 2214 fits against the inner end wall of the stepped cavity, which can fill the gap between the needle sleeve 221 and the cavity, thereby restricting the radial movement space of the needle sleeve 221 and ensuring that the needle sleeve 221 does not move radially in the working state. The combination of the two satisfies the stability of the probe 22 after it is installed in the combined substrate 21, and meets the testing requirements.

[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
