Description

Technical Field

[0001] This utility model relates to a high-density miniaturized connector, and more particularly to a high-density miniaturized connector suitable for the 153FBGA chip model. Background Technology

[0002] With the development of science and technology, electronic chips have been widely used in various electronic products. After mass production of chips, it is necessary to test their conformity to select out unqualified chips and retain qualified ones. However, in the current field of semiconductor chip testing, test sockets mainly consist of a lower test socket body, test probes, and a lower test socket probe holding plate to complete the testing of single-sided pin array chips. While these sockets are designed for testing single-sided pin array chips, for new packaging technologies such as double-sided pin array chips, especially the main chip face of stacked semiconductor chips, these test sockets lack the function of simultaneously testing both the upper and lower sides of the chip.

[0003] High-density miniaturized connectors are interfaces used to connect various electrical components in chips and testing equipment. They ensure the stability of electrical signals and data transmission, thereby guaranteeing the accuracy and reliability of chip testing.

[0004] A search revealed the patent: Chip Test Socket (CN216979234U), which includes a main body comprising a base and a top cover. The top cover is fitted onto the base, and the base has an electrical connector. The electrical connector includes an actuating end, an upper connecting end, a lower connecting end, and a fixing end. The actuating end is connected to the upper connecting end, and the fixing end includes a fixing foot and an extending foot. The base has a chip placement slot, with partition plates on both sides forming a fixing slot. The bottom of the base has an extending hole through which the fixing foot and extending foot pass. The top cover has receiving slots on both sides, with the bottom surface of the receiving slots sloping inwards from top to bottom. The actuating end is positioned within the receiving slot and abuts against the bottom surface of the receiving slot. The base has locking slots on both sides, and the top cover has hooks that mate with the locking slots. While the above method also uses a pressing mechanism to clamp the product, its opening angle is limited, making it prone to interference during replacement and causing inconvenience.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of high-density miniaturized connector with a new structure, making it more valuable for industrial applications. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a high-density miniaturized connector includes a base 1, a placement groove 2 in the center of the base 1, an adapter seat 3 for placing a product connected in the placement groove 2, a contact plate 4 for contacting the product connected in the adapter seat 3, movable grooves 5 on the left and right sides of the base 1, a cover plate 6 slidably connected to the base 1 through the movable grooves 5, a cover plate spring 7 connected between the base 1 and the cover plate 6, a cover plate pin 8 connected to the cover plate 6 located in the movable groove, the cover plate pin 8 connected to one end of a clamping connecting rod 9 for clamping the product, a connecting rod pin 10 passing through the middle of the clamping connecting rod 9, the connecting rod pin 10 connected to one end of a connecting rod 11, the other side of the connecting rod 11 connected to a base pin 12 mounted on the base 1, and the other end of the clamping connecting rod 9 connected to a clamping block 13 for clamping the product.

[0021] In this embodiment, spring mounting slots for placing cover springs are provided at the corners of both the base 1 and the cover plate 6, and two cover springs 7 are provided at each corner of both the base 1 and the cover plate 6. The multiple cover springs ensure that the cover plate can stably press the connecting rod against the product during operation.

[0022] In this embodiment, the base 1 has a guide groove 14, and the cover plate 6 is connected to a guide block 15 that slides within the guide groove. A guide strip 16 is connected to the guide groove 14, and the guide block 15 has a guide groove that slides along the guide strip. This improves the accuracy of the clamping.

[0023] In this embodiment, the clamping block 13 and the clamping connecting rod 9 are integrally formed to ensure the firmness of the clamping block and the clamping connecting rod.

[0024] In this embodiment, the adapter 3 is provided with a guide edge for product placement. This facilitates the quick and easy insertion of the product into the adapter, improving both accuracy and installation efficiency.

[0025] The working principle of this utility model is as follows: like Figure 4 As shown, after the cover plate is fully pressed down, i.e., the cover plate contacts the base, at this time, under the action of the base pin, the clamping connecting rod is tilted up by the connecting rod, forming an almost 90° angle with the base. After the clamping connecting rod is fully opened, the product is placed in the adapter seat and contacts the contact plate. Then, the cover plate is slowly lifted, and under the action of the cover plate spring, the cover plate returns to its initial position. At this time, under the action of the connecting rod pin and the base pin, the clamping block on the clamping connecting rod presses the product (e.g., Figure 3 As shown in the figure, after the product is clamped, the test socket is placed on the corresponding test fixture for testing.

[0026] The testing fixture in this utility model is prior art known to those skilled in the art and will not be described in detail here.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
