[0023] See also Figures 1 to 4, is a chip socket connector in some embodiments of the utility model, which is compatible with chips 3 of various thickness specifications for plugging and use, and is mainly used in wireless communication base stations. The chip socket connector may include an insulating colloid 1 and a metal shell 2 detachably connected to the insulating colloid 1, and the chip socket connector also includes a contact terminal 4 arranged in the insulating colloid 1 and used to connect to the chip 3. The insulating colloid 1 is provided with a terminal groove 15 for installing the contact terminal 4. The contact terminal 4 can be used for transmitting current or signal of the chip 3. After the insulating colloid 1 and the metal shell 2 are connected, an installation cavity 11 for installing the chip 3 is formed, and the installation cavity 11 is roughly rectangular.
[0024] like Figure 3 and Figure 4 As shown, the metal shell 2 includes a shell body 21, a first spring piece 22 and a second spring piece 23 which are separately arranged on the shell body 21, the free end of the first spring piece 22 and the free end of the second spring piece 23 are both arranged toward the mounting cavity 11, the first spring piece 22 and the second spring piece 23 are approximately located in the middle position of the shell body 21, when the chip 3 is inserted into the mounting cavity 11, the free end of the first spring piece 22 and the free end of the second spring piece 23 are both in contact with the chip 3, the free end of the first spring piece 22 and The free ends of the second spring pieces 23 have a predetermined gap with the bottom wall of the mounting cavity 11 in the initial state. In the present embodiment, the minimum distances between the free ends of the first spring pieces 22 and the second spring pieces 23 and the bottom wall of the mounting cavity 11 are 1.7 mm, and the distance between the bottom wall of the shell body 21 and the bottom wall of the mounting cavity 11 is 2.1 mm, which can accommodate the insertion of chips 3 of various thicknesses. In some other embodiments, the above distances can be adjusted according to actual conditions, which is not specifically limited here.
[0025] like Figure 4 As shown, when the chip 3 is inserted into the mounting cavity 11, the first spring piece 22 and the second spring piece 23 form elastic interference with the chip 3, and the first spring piece 22 and the second spring piece 23 retreat and press the surface of the chip 3 to form an elastic clamping force to ensure that the chip 3 forms a reliable contact with the contact terminal 4. When the chip 3 is inserted, the first spring piece 22 and the second spring piece 23 retreat from the initial position and rise to a position tangent to the upper surface of the chip 3. According to the thickness of the chip 3, the spring piece can retreat and rise to different positions to press the chip 3, so as to be compatible with the insertion and use of chips 3 of different thicknesses. It can be understood that the chip socket connector normalizes and integrates product specifications by adding an elastic pressing sheet structure, meets the application requirements of different scenarios, increases the elastic tolerance of the product, and is compatible with the use of chips 3 of different thickness specifications.
[0026] The mounting cavity 11 has an open end, and the first elastic sheet 22 is arranged closer to the open end than the second elastic sheet 23. Figure 4As shown, the first spring piece 22 includes a plurality of contact portions 221, and a separation groove 222 is provided between each adjacent contact portion 221. The number of the contact portions 221 is preferably three, which can increase the contact area between the first spring piece 22 and the chip 3, so that the chip 3 and the first spring piece 22 are clamped more firmly. The setting of the separation groove 222 can reduce the positive stress of the chip 3 when plugging and unplugging.
[0027] The metal shell 2 further includes an anti-retraction spring sheet 25 disposed on the shell body 21, and the free end of the anti-retraction spring sheet 25 is disposed toward the mounting cavity 11. When the metal shell 2 is connected to the insulating colloid 1, the free end of the anti-retraction spring sheet 25 abuts against the inner wall of the insulating colloid 1 to prevent the metal shell 2 from escaping from the insulating colloid 1. Furthermore, there are two anti-retraction spring sheets 25, and the two anti-retraction spring sheets 25 are symmetrically disposed about the central axis of the shell body 21.
[0028] A stopper 12 is provided on the side of the insulating colloid 1 , and the metal shell 2 further includes a locking portion 26 provided on the side of the shell body 21 and corresponding to the stopper 12 to ensure the positioning between the metal shell 2 and the insulating colloid 1 .
[0029] The metal shell 2 also includes a retaining portion 27 arranged on the side of the shell body 21. A mounting groove 13 for installing the retaining portion 27 is provided on the side of the insulating colloid 1. The retaining portion 27 is roughly U-shaped. The mounting groove 13 is arranged along the length direction of the shell body 21. When the retaining portion 27 is inserted into the mounting groove 13, it can be ensured that the metal shell 2 cannot fall out from the shell body 21 in the height direction, thereby completing the positioning of the metal shell 2 in the height direction.
[0030] The metal shell 2 further includes a positioning portion 28 disposed on the shell body 21 . When the metal shell 2 is connected to the insulating colloid 1 , the free end of the positioning portion 28 abuts against the outer wall of the insulating colloid 1 to cooperate with the positioning portion 28 to complete the positioning of the metal shell 2 and the insulating colloid 1 .
[0031] The insulating colloid 1 is provided with a through portion 14 , which is connected to the mounting cavity 11 . When the chip 3 needs to be taken out, the chip 3 can be pushed out through the through portion 14 . The provision of the through portion 14 facilitates the removal of the chip 3 .
[0032] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
