[0027] See also Figures 1 to 5, is a DDR5 connector in some embodiments of the utility model. The DDR5 connector is an SMT structure. The DDR5 connector includes a mounting shell 1 and a clip 2 mounted on both sides of the mounting shell 1. The clip 2 is used to lock and prevent the memory stick from falling off and unlock and eject it. In addition, a base 11 corresponding to the mounting clip 2 is provided at both ends of the mounting shell 1. The base 11 includes a positioning base 111 and a clamping body 112 integrally formed with the positioning base 111. The clamping body 112 is located above the positioning base 111. The width of the clamping body 112 is smaller than the width of the positioning base 111. The clip 2 includes a positioning portion 21 and a clamping portion 22 integrally formed with the positioning portion 21. The positioning portion 21 is located above the clamping portion 22. The width of the positioning portion 21 matches the width of the clamping body 112. The width of the positioning portion 21 can be close to or consistent with the width of the clamping body 112.

[0028] It can be understood that since a fan is used to dissipate heat for the DDR5 connector during the heat dissipation process, the heat dissipation wind is blown in through the base 11 at both ends of the DDR5 connector to dissipate heat for the entire DDR5 connector. Compared with the traditional SMT structure connector in which the ear buckle width is consistent with the main body width, the width of the positioning body 112 above the base 11 of the present application is narrowed, and at the same time, the positioning portion 21 above the fastener 2 is also narrowed, which can effectively increase the heat dissipation air circulation space and enhance the heat dissipation effect.

[0029] Specifically, the width of the positioning body 112 is 4 mm to 4.2 mm, and the width of the positioning portion 21 is 4 mm to 4.2 mm. In this embodiment, the width of the positioning base 111 is 6 mm, and the widths of the positioning body 112 and the positioning portion 21 are preferably 4.1 mm. The connection between the positioning base 111 and the positioning body 112 has a connection chamfer.

[0030] like Figure 3 and Figure 5 As shown, the base 11 further includes a mounting groove 113, the upper portion of the positioning body 112 extends outward to form a limiting arm 114, the mounting groove 113 is located below the limiting arm 114, the clamping portion 22 is installed in the mounting groove 113, and a receiving groove 211 for receiving the limiting arm 114 is provided between the positioning portion 21 and the clamping portion 22. It can be understood that when the limiting arm 114 is received in the receiving groove 211, the side wall of the limiting arm 114 abuts against the side wall of the positioning portion 21, the upper side surface of the limiting arm 114 is located above the receiving groove 211, and the lower side surface of the limiting arm 114 is located below the receiving groove 211, and the limiting arm 114 can form a limiting effect on the entire buckle 2.

[0031] At the same time, a convex portion 115 is provided on the mounting groove 113, and a connecting portion 221 is provided on the clamping portion 22 to cooperate with the convex portion 115. In the present embodiment, the convex portion 115 is connected to the limiting arm 114 and is located below the limiting arm 114. Since the mounting shell 1 and the fastener 2 are both made of plastic material, both have a certain elasticity. When the clamping portion 22 is located in the mounting groove 113, the clamping portion 22 can be clamped in the mounting groove 113 through the cooperation of the convex portion 115 and the connecting portion 221, thereby forming further limitation.

[0032] The mounting groove 113 is provided with a fixing portion 116, and the clamping portion 22 is provided with a fixing boss 222 that is arranged in cooperation with the fixing portion 116. In the present embodiment, the fixing portion 116 is a concave circular groove portion, and the fixing boss 222 is in the shape of a protruding cylinder that matches the shape of the circular groove portion, and the fixing portion 116 and the fixing boss 222 cooperate with each other to position the clamping portion 22 in the mounting groove 113. In some other embodiments, the cross-sectional shapes of the fixing boss 222 and the fixing portion 116 may also be triangular, quadrilateral or other shapes, which are not specifically limited here.

[0033] The lower portion of the mounting groove 113 penetrates the positioning base 111 , and the width of the lower portion of the clamping portion 22 matches the width of the portion of the mounting groove 113 that penetrates the positioning base 111 , so as to further limit the clamping portion 22 .

[0034] In some embodiments, a through hole 223 is further provided in the clamping portion 22, and the through hole 223 is arranged along the length direction of the clamping portion 22. The base 11 also includes a connecting portion 117 connected to the through hole 223. The setting of the through hole 223 can also effectively increase the heat dissipation air circulation space and enhance the heat dissipation effect.

[0035] Furthermore, the DDR5 connector also includes a plurality of terminals 3 arranged in parallel along the length direction of the mounting housing 1, and the mounting housing 1 is provided with a receiving groove 13 for installing the terminals 3. The terminals 3 are used for conducting the welding end with the PCB board and the contact end with the memory stick to realize data interaction.

[0036] In addition, the DDR5 connector also includes a fixing plate 4. A plug-in slot 14 for installing the fixing plate 4 is provided on the middle of the installation shell 1 and the positioning base 111. The fixing plate 4 is used to increase the holding force after the installation of the installation shell 1 is completed. The number of the fixing plates 4 is preferably three.

[0037] 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.
