[0002] A chip, namely a central processing unit (CPU for short), as a core component for data operation and control, needs to be buckled and fixedly installed on a circuit board during use to electrically connect the chip to the circuit board. When buckling upwards, it is necessary to manually hold the chip and place it for buckling, and the installation convenience is poor.

[0003] To facilitate the installation of the chip, Chinese Patent No. CN201820210165.5 discloses an electrical connector for electrically connecting a chip module. The electrical connector includes a base, a guiding frame pivotally connected to the base, a clamping member for installing the chip module and slidable relative to the guiding frame, and a pressing plate pivotally connected to the base; the clamping member is pressed by the pressing plate. The guiding frame includes a cross beam portion and a frame opening portion surrounded by the cross beam portion. The cross beam portion includes a first cross beam portion pivotally connected to the base, two second cross beam portions arranged side by side on both sides of the first cross beam portion, and a third cross beam portion connected to one side of the two second cross beam portions and opposite to the first cross beam portion. The third cross beam portion is recessed compared with the first and second cross beam portions, and sliding rails are provided on both second cross beam portions. The guiding frame is provided with a stop block at the third cross beam portion to abut against the lower part of the clamping member during the insertion or extraction of the clamping member, which can fully protect the chip module and prevent it from being bruised.

[0004] The above chip installation method of the electrical connector is to fix the chip on the clamping member by adding structures such as a guiding frame, a clamping member and a pressing plate, and then buckle and install it on the base, so that the structure of the electrical connector is relatively complex, the assembly steps are more cumbersome, and the chip is likely to fall off during the assembly process.

Compared with the prior art in which the upper buckle and the clamping piece are detachably connected or a guiding frame is added to install and fix the chip, the chip installation structure of this solution is simpler, with fewer assembly steps, improving the chip installation efficiency. Moreover, by locking the chip between the upper buckle and the clamping piece, the chip is installed more firmly, and it is not easy for the chip to fall off during the assembly process.

[0030] To better understand the technical solution and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0031] As Figures 1 to 4 shown, a chip fastening device 10 in an embodiment is used to fasten and install a chip on a connector body 21. The connector body 21 is provided with a conductive contact area. The chip fastening device 10 includes an upper buckle 100 and a clamping piece 200. The upper buckle 100 is rotatably connected to the connector body 21. The upper buckle 100 is provided with an exposed opening 101. One side of the clamping piece 200 adjacent to the upper buckle 100 is provided with a buckle groove 201 for buckling the chip. The chip is used to abut against the conductive contact area when the upper buckle 100 is fastened to the connector body 21. The upper buckle 100 and the clamping piece 200 are locked and fixedly connected to jointly clamp the chip.

[0032] In this embodiment, the upper buckle 100 and the clamping piece 200 are locked and fixedly connected. It should be understood that the connection method is not limited. The clamping piece 200 can be fixedly connected to the upper buckle 100 by forms such as hot melting, hot riveting, and laser welding. Then, the chip is fixed to the clamping piece 200 manually or by a jig, so that the chip, the clamping piece 200, and the upper buckle 100 are fixed. Finally, the upper buckle 100 is buckled to install the chip on the connector body 21.

[0033] The above chip fastening device 10 locks and fixedly connects the upper buckle 100 and the clamping piece 200 together, and then fixes the chip between the upper buckle 100 and the clamping piece 200. The upper buckle 100 is rotatably connected to the connector body 21. By fastening the upper buckle 100, the chip can be installed and fixed on the connector body 21. Compared with the prior art in which the upper buckle 100 and the clamping piece 200 are detachably connected, or a guiding frame is added to install and fix the chip, the chip installation structure of this solution is simpler, with fewer assembly steps, improving the chip installation efficiency. Moreover, by locking the chip between the upper buckle 100 and the clamping piece 200, the chip is installed more firmly, and it is not easy for the chip to fall off during the assembly process.

[0034] As Figure 4 shown, further, the buckle groove 201 is a regional space formed by a plurality of hooks 212 together, and each hook 212 protrudes from the side of the clamping piece 210 facing away from the upper buckle. In other embodiments, the buckle groove 201 is not limited to the regional space formed by a plurality of hooks together. For example, the hook can also be replaced by a convex bump.

[0035] As Figures 1 to 4 shown, in one embodiment, the upper buckle 100 is connected to the clamping piece 200 by hot melting or hot riveting. In this embodiment, the upper buckle 100 is connected to the clamping piece 200 by hot melting or hot riveting so that the clamping piece 200 is fixedly connected to the upper buckle 100, facilitating the subsequent installation and fixation of the chip. The connection method between the upper buckle 100 and the clamping piece 200 is not limited. In other embodiments, it can also be by laser welding, screwing, etc.

[0036] As Figures 1 to 4 shown, in one embodiment, the clamping piece 200 includes a connected clamping piece main body 210 and a connecting convex column 220. The buckle groove 201 is opened on the clamping piece main body 210, and the connecting convex column 220 is connected to the upper buckle 100 by hot melting or hot riveting. In this embodiment, the connecting convex column 220 protrudes on the clamping piece 200 to facilitate the subsequent fixation of the clamping piece 200 to the upper buckle 100 by hot melting, hot riveting, etc.

[0037] As Figure 1 and Figure 2 shown, in one embodiment, the connecting convex column 220 is located on the side of the clamping piece main body 210 adjacent to the upper buckle 100. In this embodiment, the connecting convex column 220 is located on the side of the clamping piece main body 210 adjacent to the upper buckle 100, that is, the connecting convex column 220 should be arranged in the direction facing the upper buckle 100 to facilitate the subsequent fixation of the clamping piece 200 to the upper buckle 100 by hot melting, hot riveting, etc.

[0038] As Figures 1 to 3As shown, in one embodiment, the upper buckle 100 is provided with a fixing hole 102, and the connecting convex post 220 is located in the fixing hole 102. In this embodiment, the upper buckle 100 is provided with a fixing hole 102, and the connecting convex post 220 is located in the fixing hole 102. It can be understood that by passing the connecting convex post 220 through the fixing hole 102 provided in the upper buckle 100, and then thermally melting or thermally riveting the connecting convex post 220 at the fixing hole 102, the clamping piece 200 is fixed in the upper buckle 100.

[0039] As Figures 1 to 4 shown, in one embodiment, the number of both the connecting convex posts 220 and the fixing holes 102 is multiple. In this embodiment, the connecting convex posts 220 protrude at the four diagonal corners of the clamping piece 200, and the fixing holes 102 are provided at the four diagonal corners of the corresponding upper buckle 100 to improve the connection strength between the clamping piece 200 and the upper buckle 100.

[0040] As Figure 3 shown, in one embodiment, the upper buckle 100 is further provided with a limiting groove 103 communicating with the fixing hole 102, and the cross-sectional area of the limiting groove 103 is larger than that of the fixing hole 102, that is, the notch diameter of the limiting groove 103 is larger than the aperture of the fixing hole 102. In this embodiment, the upper buckle 100 is further provided with a limiting groove 103 communicating with the fixing hole 102. At the same time, a clamping portion 221 matching the shape of the limiting groove 103 is provided on the connecting convex post 220. When the connecting convex post 220 is thermally melted or thermally riveted at the fixing hole 102, the connection strength between the clamping piece 200 and the upper buckle 100 is improved through the limiting cooperation between the clamping portion 221 and the limiting groove 103.

[0041] As Figure 3 shown, in one embodiment, the cross-sectional area of the limiting groove 103 gradually increases from the direction adjacent to the fixing hole 102 to the direction away from the fixing hole 102, that is, along the direction away from the side of the clamping piece 200 facing away from the upper buckle 100, the notch diameter of the limiting groove 103 gradually increases. In this embodiment, the cross-sectional area of the limiting groove 103 gradually increases from the direction adjacent to the fixing hole 102 to the direction away from the fixing hole 102, that is, the limiting groove 103 as a whole has an inverted conical structure, which is convenient for the connection between the connecting convex post 220 and the upper buckle 100.

[0042] As Figures 1 to 4 shown, in one embodiment, both the fixing hole 102 and the limiting groove 103 are provided adjacent to the periphery of the upper buckle 100. In this embodiment, both the fixing hole 102 and the limiting groove 103 are provided adjacent to the periphery of the upper buckle 100. It can be understood that a communicating fixing hole 102 and a limiting groove 103 are provided at the periphery of the upper buckle 100. Correspondingly, the connecting convex post 220 protrudes at the periphery of the clamping piece 200, that is, thermal melting or thermal riveting is performed at the periphery of the clamping piece 200 and the upper buckle 100, which is convenient for operation.

[0043] As Figure 5 shown, the present application further provides an electrical connector 20, which includes a connector body 21, a mounting base 22, a circuit board 23, a base 24, and the chip fastening device 10 of any of the above embodiments. The mounting base 22 is provided with a mounting groove for mounting a chip. The circuit board 23 is clamped between the mounting base 22 and the base 24, and the circuit board 23 is electrically connected to the chip.

[0044] Compared with the prior art, the present disclosure has at least the following advantages:

[0045] For the above-mentioned chip fastening device 10, the upper buckle 100 and the clamping piece 200 are locked and fixedly connected together, and then the chip is fixed between the upper buckle 100 and the clamping piece 200. By rotatably connecting the upper buckle 100 with the connector body 21, closing the upper buckle 100 can fix the chip on the connector body 21. Compared with the prior art in which the upper buckle 100 and the clamping piece 200 are detachably connected, or a guiding frame is added to install and fix the chip, the chip installation structure of this solution is simpler, with fewer assembly steps, improving the chip installation efficiency. Moreover, by locking the chip between the upper buckle 100 and the clamping piece 200, the chip is installed more firmly, and the chip is not likely to fall off during the assembly process.

[0046] The above-described embodiments only represent several implementation manners of the present disclosure, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
