[ detailed description ] embodiments

Hereinafter, embodiments of the present invention will be described with reference to fig. 1 to 10. The invention relates to a chip connector combination, which accommodates a chip module, establishes electrical connection between the chip module and a circuit board, and simultaneously comprises a fixing structure for fixing the chip module and a heat dissipation module positioned above the chip module. The main improvement of the present invention lies in the fixing structure, which will be mainly described in detail below, and some structures are not shown or described in detail.

Referring to fig. 3-4, the chip connector assembly includes a holder 200, an electrical connector (not shown, refer to U.S. patent application publication No. 20190088572), and a back plane 400, wherein the holder 200 is mounted on the front surface of a circuit board 300, and the back plane 400 is mounted on the back surface of the circuit board. The holder 200 is a frame structure, the electrical connector is located in the holder 200, the chip module (Central Process Unit)600 is mounted on the chip carrier 500 and then placed on the electrical connector, and is limited by the holder 200, and the chip module 600 is electrically connected to the conductive terminals disposed in the electrical connector. A heat sink 700 is seated on the chip module 600 and is fixed to the chip carrier 500 and the fixing base 200. It should be noted that the heat sink 700 and the circuit board 300 are not complete structures, for example, the heat dissipation holes of the heat sink 700 are not shown, and the circuit board may be thicker, but these will not affect the understanding of the present invention.

The mounting base 200 includes a substrate 210 and a preload support structure 220. The substrate 210 is a frame-shaped structure, and the substrate 210 includes a bottom plate 212 and a pair of side plates 214 extending upward from two opposite sides of the substrate, the pair of side plates 214 are spaced apart from each other in a transverse direction of the bottom plate, the transverse direction is perpendicular to a vertical direction, the side plates 214 extend upward in the vertical direction, and each side plate 214 is longitudinal, that is, each side plate extends in the longitudinal direction. The bottom plate 212 is provided with an opening 217 and an electrical connector is located in said opening 217 through which the electrical connector is connected to the circuit board 300. A plurality of fixing nuts 216 are fixed on the base plate 212, and the back plate 300 is rotatably fixed to the fixing nuts 216 by bolts 402, thereby fixing the back plate 400 to the circuit board 300, which is tightly clamped between the substrate 210 and the back plate 400.

The base plate 210 is provided with a torsion member 222 and a column 224 at four opposite corners thereof, the torsion member 222 is a linear metal wire body extending along the longitudinal direction, the bottom plate 212 is bent upwards to form a fixing lug 218 at the inner edge thereof, and one end of the torsion member 222 is L-shaped and fixed in a circular hole provided in the fixing lug 218; the main portion 2221 of the torsion member 222 extends along the inner side of the side plate 214. The column 224 is placed in the vertical direction and can move in the vertical direction. The other end of the torsion member 222 is bent in a U-shape and fixed in a hole provided at the lower end of the column member 224. The bottom plate 212 is bent upward and inward at its outer edge to form a fixing piece 219, the fixing piece 219 is located near the column 224, and the fixing piece 219 can limit the torsion member between the side plate 214 and the bottom plate 212 to prevent the torsion member 222 from being separated upward. The column 224 is in the shape of a pin, i.e., a three-stage structure that is enlarged from top to bottom, and is disposed above and below. The torsion member 222 and the post 224 form the preload support structure 220 described above.

To ensure that torsion members 224 do not disengage from base plate 212 when subjected to a force to create a large torque, preload support structure 220 further includes a restraint 225. A plurality of posts 226 are secured to the base 212, each post 226 cooperating with a side plate 214 for securing the torsion member 222 in a lateral direction. Each of the cylindrical bodies 226 is provided with an annular groove 227 adjacent to the top surface thereof for receiving an annular washer 228, the inner periphery of the washer is provided with four inwardly projecting claw portions 229 which are symmetrical to each other, the washer 228 is forced to be fitted down into the cylindrical body 226, and the four claw portions 229 are deformed to pass through the cylindrical body 226 until the claw portions 229 are caught in the annular groove 227. It should be noted that the washer 228 presses down on the torsion member 222, so that the main body portion 2221 of the torsion member 222 in the longitudinal direction can only move in the horizontal direction, i.e. the torsion member 224 is prevented from being separated from the base plate 212. The post 226 and washer 228 form the restraint 225.

The chip carrier 500 is a frame structure, which includes a plurality of fastening arms 502 for fixing the chip module 600 in the chip carrier. Through holes 504 are formed in the chip carrier for posts 224 to pass through, and through holes 508 are formed in the chip carrier for posts 226 to pass through to restrain base 704 of heat spreader module 700. A plurality of restraining tabs 506 are positioned alongside the through holes 506 to restrain the base 704. The heat sink module 700 has through holes 702 formed at four corners of the base 704 thereof for receiving the cylindrical body 224, the nuts 720 are rotated into the top end of the cylindrical body 224, and not only are fixed on the top end of the cylindrical body 224, but also abut against the base 704 of the heat sink module, the base 704 reacts on the cylindrical body 224 to drive the cylindrical body 224 to move upward, and the cylindrical body drives the end of the torsion member to tilt up and down when moving upward, and the torsion member is twisted, thereby enhancing the torsion thereof. The torsion piece generates downward torsion, so that the gravity of the heat dissipation module is dispersed, and the local stress is reduced. It is noted that the torsion member 222 has a certain torsion force when the pillar 224 is seated on the base plate 210, i.e. is in a preloaded condition. The force of the nut 720 on the heat sink module causes the column 224 to be lifted upwards, increasing the torsion angle and the torsion force of the torsion member.

It will be appreciated that the washer 228 is pressed directly into the post 226 by pressure to thereby firmly press against the torsion member 222, trapping the torsion member between the bottom plate 212 and the side plate 214, preventing the torsion member from being pulled upwardly. The press-in of the washer 228 is a relatively easy method of manufacture and installation, and the press-in action is also suitable for automated assembly processes. In this embodiment, the bottom plate can also be formed with a recess for receiving and fixing the pillar 224, which is also beneficial to enhance the fixing of the pillar.

Referring to fig. 10, the washer 228 has an upper surface flush with the upper surfaces of the four jaws, and a lower surface projecting downward from the lower surfaces of the four jaws.

The above description is only a part of the embodiments of the present invention, and not all embodiments, and any equivalent variations of the technical solutions of the present invention, which are made by those skilled in the art through reading the present specification, are covered by the claims of the present invention.
