Description

Technical Field

[0001] This utility model relates to the field of chip technology, and in particular to a positioning mechanism for use in a socket fastener. Background Technology

[0002] like Figures 4-6 As shown, existing socket fasteners generally include a fastener cover plate c, a base a, and a chip holder g; the chip g is fixed on the chip holder g, and the chip holder g is placed directly on the base a via a guide post d, as shown. Figure 1 As shown, when one side of the fastener cover c is released, the chip h is affected by the elastic rebound of the terminal f. The side that is released first, as shown... Figure 2 As shown, chip h will first be lifted by terminal f, but on the other side, due to the pressure of the fastener cover plate c, as... Figure 3 As shown, the chip h remains in its original position. At this time, the chip h flips inside the socket holder, which can easily cause the terminal f to scratch the chip PAD, resulting in problems such as deformation of the terminal f and scratches on the chip PAD. This makes it unusable multiple times, increases the cost of use, and fails to meet market demand. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figure 7 As shown in the figure, the positioning mechanism for the socket fastener provided in this embodiment includes a guide post (13), a spring (14), and a sleeve (12); both the sleeve (12) and the spring (14) are sleeved on the guide post (13). Those skilled in the art will understand that the guide post (13) is fixed on the base of the socket fastener. When the chip holder is placed on the base, the sleeve (12) is inserted into the positioning hole on the chip holder and abuts against the chip holder. Then, the fastener cover is fastened to the base, forcing the spring (14) to a compressed state. When the fastener cover is opened, the spring (14) returns to a free state, causing the sleeve (12) to be pushed upward, first lifting the chip as a whole to a certain height, so that the chip contact surface is away from the socket terminal contact surface, and then the chip is taken out. This will not cause the chip to be scratched by the socket due to tilting when picking up the chip, thus improving the service life of the chip or the socket and meeting market demand.

[0036] Furthermore, the guide post (13) includes a first post (132) and a second post (133); the first post (132) and the second post (133) are connected end to end to form an integral structure; the outer diameter of the second post (133) is larger than the outer diameter of the first post (132); the outer diameter of the second post (133) matches the inner diameter of the spring (14); the spring (14) is sleeved on the first post (132) and the second post (133). Those skilled in the art will understand that when the spring (14) is compressed, most of the compressed spring (14) is sleeved on the second post (133). Since the outer diameter of the second post (133) is the same as that of the spring (14), this can limit the spring (14) and prevent the spring (14) from shaking. The original SOCKET fastener guide post (d) is designed as a spring mechanism (1), which can not only serve the original function of the guide post (d), but also reduce the chip PAD from being scratched by the socket terminals.

[0037] Furthermore, the sheath (12) includes a first ring (121) and a second ring (122); the second ring (122) is sleeved on the outer wall of the first ring (121) and fixed to the first ring (121); the outer diameter of the second ring (122) is larger than the outer diameter of the spring (14); the outer diameter of the first ring (121) is the same as the inner diameter of the spring (14); the spring (14) abuts against one side of the second ring (122), so that the sheath (12) slides on the first column (132). Those skilled in the art will understand that the other side of the second ring (122) is used to abut against the positioning hole (g1) on the chip holder (g).

[0038] Furthermore, the guide post (13) also includes a third post (134); the third post (134) is fixed to the end of the second post (133) away from the first post (132); the outer diameter of the third post (134) is larger than the outer diameter of the second post (133), such that a boss is formed at the connection between the third post (134) and the second post (133); the end of the spring (14) away from the second ring (122) abuts against the boss. Those skilled in the art will understand that the spring (14) abuts between the boss and the second ring (122).

[0039] Furthermore, the outer wall of the third column (134) away from the end of the second column (133) is provided with a serrated structure (1311). Those skilled in the art will understand that the outer side of the bottom of the guide column (13) adopts a serrated structure, which can be directly riveted to the base hole, simplifying the assembly process and ensuring the stability of the connection between the guide column (13) and the base (a).

[0040] Furthermore, the end of the first ring (121) away from the spring (14) has a smaller diameter than the end of the first ring that is closer to the spring (14).

[0041] Those skilled in the art will understand that one end of the first ring (121) is chamfered to facilitate guidance during assembly.

[0042] Furthermore, the positioning mechanism for the socket fastener provided in this embodiment also includes a nut (11); the end of the first column (132) away from the second column (133) is provided with an external thread (131) that matches the nut (11). Those skilled in the art will understand that the top of the first column (132) is directly locked with the nut (11) to ensure that the sheath (12) does not fall off.

[0043] Furthermore, the nut (11) has a chamfer at its top. Those skilled in the art will understand that the chamfer on the nut (11) facilitates guidance when it passes through the chip carrier (g).

[0044] Furthermore, the top of the nut (11) is also provided with a slot (112). Those skilled in the art will understand that the slot (112) on the top of the nut (11) facilitates disassembly with a conventional screwdriver.

[0045] Furthermore, the compressive force of the spring (14) is greater than several times the weight of the chip (h) and the chip carrier (g). Those skilled in the art will understand that this is to ensure that the spring (14) can easily lift the chip (h) and the chip carrier (g).

[0046] Furthermore, the working range of the spring (14) is greater than the free state height of the socket terminal (f). Those skilled in the art will understand that after the spring (14) lifts the chip (h) and the chip support (g) away from the contact surface of the terminal (f), the chip PAD cannot contact the terminal (f).

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
