Description

Chip connector This invention relates to a chip connector. Related prior art, see CN211980932U, involves a cover plate pivotally mounted to a mounting base, which can be rotated open relative to the base. The cover plate is mounted on the circuit board along with the mounting base, requiring multiple opening and closing cycles before and after chip module installation. Due to the use of a rotating screw structure, this method consumes considerable time and involves numerous processes. Therefore, it is indeed necessary to improve the chip connector. An embodiment of this application provides a chip connector for electrically connecting a chip module and a circuit board. The chip connector includes a body carrying conductive terminals, a frame surrounding the body, and a switching plate. The body and frame are mounted on the circuit board. The switching plate has a first end and a second end opposite to each other. The first end is pivotally mounted to the corresponding first end of the frame, which allows the switching plate to have an outward rotation tendency. The second end is provided with a first fastening part, and the corresponding second end of the frame is provided with a second fastening part. The first fastening part is pressed and fastened to the second fastening part. Compared with the prior art, the present invention has the following advantages: the pressure plate is initially fixed by pressing the first and second fastening parts, which greatly simplifies the assembly process. The following describes specific embodiments of the chip connector of the present invention with reference to Figures 1 to 9. Please refer to Figures 1 to 9. This invention discloses a chip connector 100 for electrically connecting a chip module 300 and a circuit board 200. The chip connector 100 includes a body 10 carrying conductive terminals (not shown), a frame 20 surrounding the body 10, and a switching plate 30. The body 10 and frame 20 are mounted on the circuit board 100. The switching plate 30 has a first end 311 and a second end 312. The first end 311 is pivotally mounted to the corresponding first end 211 of the frame 10, allowing the switching plate 30 to have an outward rotation tendency. The second end 312 has a first retaining part 32, and the corresponding second end 212 of the frame 20 has a second retaining part 22. The first retaining part 32 is pressed and secured to the second retaining part 22. This invention allows the switching plate 30 to be fixed to the frame 20 by manually pressing the first retaining part 32, simplifying the process compared to the prior art which uses a screw structure for rotational locking. The invention will now be further described in the order of assembly. As shown in Figures 1-2, a protective cover 40 is installed on the top of the main body 10. Besides protecting and dustproofing the main body 10, the cover also provides vacuum suction during movement. The conductive terminals of the main body 10 are soldered to the front of the circuit board 200. A back plate 50 is installed on the back of the circuit board 200. Hex studs 71 ​​and 72 extend upwards to the front of the circuit board 200 through the through holes (not labeled) in the back plate 50 and the circuit board 200. The pressure plate 30 is mounted at its first end 311 to the first end of the frame 20 via a torque shaft 33. The torque shaft 33 provides torque, causing the pressure plate 30 to rotate upwards (away from the main body 10). At this time, the first holding part 32 of the pressure plate 30 presses against the second holding part 22 of the frame 10, so that the pressure plate 30 is mounted parallel to the frame 10, forming an independent load-bearing device 200a, commonly referred to in the industry as an Independent Loading Mechanism (ILM). The central opening of the pressure plate 30 is covered by a dust cover 60. After the main body 10 is soldered to the circuit board 200, the independent support device 200a is placed on the front side of the circuit board 200. Two studs (hereinafter referred to as the first studs 71) pass through the positioning parts 24 provided on both sides of the frame and are fixed by rotation with nuts 81, thereby fixing the independent support device 200a to the circuit board, as shown in Figure 3. Referring to the enlarged view in Figure 4, it can be seen that the pressure plate 30 has a notch 34 for the first studs 71 ​​and nuts 81 to pass through. As shown in Figures 5-6, the first holding part 32 is a vertical piece bent downward from the rotating pressure plate 30, and has a holding protrusion 321 away from the second end. The second holding part 22 is an L-shaped piece bent upward from the frame 10, and has a holding crossbar 221 located above the holding protrusion 321. When the user presses the second end 312 of the rotating pressure plate 30, the holding protrusion 321 abuts against the holding crossbar 221, thus preventing the holding protrusion 321 from disengaging upward. Referring to Figure 7, when the chip module 300 needs to be installed, the second holding part 22 is pushed outward to unlock the first holding part 32. Under the action of the torque shaft 33, the pressure plate 30 rotates upward, exposing the body 10 and the protective cover 40. The protective cover 40 is removed to expose the body 10, which has an upward-facing chip receiving cavity (not labeled), with the contact portion of the conductive terminal protruding into the chip receiving cavity. The chip module 300 is inserted into the chip receiving cavity via the mounting member 90. The mounting member 90 is then installed between the body 10 and the pressure plate 30 after the chip module 300 is installed. Subsequently, the pressure plate 30 is rotated until its first holding part 32 is locked to the second holding part 22, as shown in Figure 8. Finally, four nuts 82 are provided and rotated to the four corresponding second studs 72 to further secure the pressure plate. As described above, when the chip module 300 is not installed, the independent support device 200a operates through the cooperation of the first and second clamping parts. The first and second clamping parts are locked by pressing, which greatly simplifies the assembly process. After the chip module 300 is installed, further screw structure locking is performed, that is, the rotational engagement of the nut and the stud to ensure that the two are stably fixed. In this process, due to the reaction force of the conductive terminals and the chip module, the torque on the pressure plate is greatly increased, and the locking of the first and second clamping parts is not stable enough, so the screw structure is required for reinforcement. In summary, it can be seen that the first retaining part 32 of the pressure plate is pressed and held to the second retaining part 22 of the frame. Simultaneously, the pressure plate 30 has a first locking fastener at its first end 311 and second end 312, and the frame has a corresponding second locking fastener. The first and second locking fasteners are matching screw structures. In this embodiment, the first stud 71 passes through the back plate 60, the circuit board 200, and the frame 10, and is fixed to the circuit board by a corresponding nut 71. The second stud 72 passes through the back plate, the circuit board, the frame, and the pressure plate, and the pressure plate is fixed by a corresponding nut 82. The frame 10 has four positioning posts 25 protruding from it, and the mounting part 90 has positioning holes 91 through which the positioning posts pass, which facilitates the initial positioning of the mounting part 90 when it is assembled into the frame. The above embodiments are preferred embodiments of the present invention, but not all embodiments. Any equivalent changes to the technical solutions of the present invention made by those skilled in the art through reading the present invention specification are covered by the claims of the present invention. 10: Body 100: Chip Connector 20: Frame 211: First End 212: Second End 22: Second Clamping Part 221: Clamping Crossbar 24: Positioning Part 25: Positioning Post 30: Pressure Plate 311: First End 312: Second End 32: First Clamping Part 321: Clamping Protrusion 33: Torque Shaft 34: Notch 40: Protective Cover 50: Back Plate 60: Dust Cover 71, 72: Studs 81, 82: Nuts 90: Mounting Part 91: Positioning Hole 200: Circuit Board 200a: Independent Support Device 300: Chip Module Figure 1 is a perspective view of the chip connector and circuit board of the present invention, wherein the body with a protective cover is mounted on the circuit board, and the independent support device is prepared to be mounted on the circuit board.
