[0025] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0026] Ginseng Figure 1-4As shown, the present invention discloses an electrical connector assembly 200, which is used to establish an electrical connection between a computer central processing unit module (abbreviated as CPU) or other chips and a circuit board 290. The electrical connector assembly 200 includes a circuit board 290, a chip connector 210 mounted on the circuit board, and the specific structure can also refer to another patent application 201911021216.5 of the applicant; as known in the art, the chip connector 210 includes a body made of insulating material and a conductive terminal fixed to the body, which is not shown in detail here; in order to fix the body on the circuit board and install the chip, the chip connector further includes a fixing seat 220 surrounding the chip connector 210, and the fixing seat 220 is made of metal material.

[0027] from Figure 1-4 As shown, a carrier seat 250 is fixed to one end of the fixing seat 220 by a pivoting manner, and a metal pressing piece 240 is fixed to the other end by a pivoting manner. The carrier seat and the pressing piece are pivoted to the opposite ends of the fixing seat respectively, and the chip 299 is first fixed to the carrier 230 and then inserted into the carrier seat 250. Subsequently, the carrier 230 and the carrier seat 250 are driven to rotate downward until the chip is installed into the chip connector 210. The pressing plate 240 is pivoted to the other end of the fixing seat 220, and it rotates downward and presses on the carrier 230 until the chip is fixed in the chip connector 210. The carrier seat 250 includes a torsion spring 252, which urges the carrier seat 250 to be in a vertical open state, so as to facilitate the insertion of the carrier 230 into the carrier seat 230.

[0028] The fixing base 220 is provided with a plurality of first fixing columns 224, 226, 222, some of which are used to fix the fixing base 220 to the circuit board 290, and some of which cooperate with the fixing parts 244, 246, 222 to fix the pressing piece 240 to the fixing base 220. The fixing base 220 further includes a plurality of second fixing columns 228, which are located at four diagonal corners, and the pressing piece 240 forms corresponding notches 248 to facilitate the passage of the fixing columns 228. It can be understood that the chip 229 located in the carrier 230 is pressed downward by the pressing piece 240 and is restricted.

[0029] Ginseng Figure 5-11As shown, the carrier 230 includes a frame-shaped portion 237 and an insertion head 232 located at one end of the frame-shaped portion. The frame-shaped portion is made of insulating material, and a metal reinforcement 238 is embedded therein. The metal reinforcement 238 is embedded by injection molding. The frame-shaped portion 237, that is, a frame-shaped structure having a large through hole extending from top to bottom, has an upper surface 2371 and a lower surface 2372 opposite to each other, and an outer side surface 2373 and an inner side surface 2374 located between the upper and lower surfaces. A chip accommodating cavity 2375 is formed between the inner side surfaces 2374. The reinforcement 238 extends horizontally and is located between the upper and lower surfaces to enhance the strength of the carrier. The insertion head 232 is formed by protruding from the outer side of one end of the frame-shaped portion 237, and is used to be inserted into the insertion groove provided in the carrier seat 250. The inner edge 2374 of the frame-shaped portion is provided with a plurality of hooks 234 and fixing feet 235, 236. The hooks 234 protrude inwardly to carry the chip 229. The fixing legs 235 , 239 are formed on the outer edge of the frame portion 237 . When the carrier 230 rotates to be horizontal, the fixing legs 235 , 239 are temporarily supported on the fixing seat 220 , waiting for the pressing member 240 to rotate until it presses on the carrier 230 .

[0030] The frame portion 237 has a pair of notches 231 on its two opposite outer sides 2373, and correspondingly, the reinforcement member 238 also has a pair of grooves 238A formed thereon to match the notches 231. Fig.10 In other embodiments, the metal reinforcement 238 is provided with a plurality of holes 238B for receiving the insulating material of the frame 237, so as to strengthen the bonding strength between the frame 237 and the reinforcement 238. In this embodiment, the metal reinforcement 238 is formed by stamping and then bending, and the notch 231 can be used to connect the material strip. In other embodiments, such as Figure 12-14 As shown, the metal reinforcement 238 is initially located and exposed outside one end of the frame 237, so that the metal plate 260 is connected to the carrier 230 through the connecting strip 262. After the strip 262 is cut, a strip connecting end 238C is left. The frame 237 can form a plurality of notches 237A to correspond to the strip connecting end 238C.

[0031] Please note that as the transmission speed increases, the number of conductive sheets increases, and the carrier 230 is limited by the miniaturization of the electrical connector structure itself, and is relatively thin. During the rotation process, the user applies force to the carrier 230, causing it to overcome the force of the torsion spring 252 and rotate downward. At this time, the carrier 230 is subjected to a large force. When the pressing plate 240 is pressed against the carrier, the force generated by the elasticity between the chip and the terminal will also act on the carrier 230. At this time, the carrier is subjected to a large force. The addition of the metal reinforcement 238 to the carrier can greatly increase its strength.

[0032] Figure 16-18The second embodiment of the present invention is disclosed. The card edge connector includes a longitudinal insulating body 510 and a card ejector 520. The insulating body is provided with a longitudinally extending central slot 512 for accommodating a PCI card. Two outer side surfaces at one end of the insulating body are provided with a vertical retaining strip 514 and a notch 516. The card ejector 520 is rotatably mounted at one end of the insulating body 510. The card ejector 520 includes a pair of elastic retaining arms 526. When the card ejector 520 rotates inwardly, the retaining arms 526 retain the retaining strip 514, thereby fixing the card ejector to the insulating body. The notch 516 is used to allow the card ejector 520 to rotate outwardly. The following focuses on the improvements of the card ejector.

[0033] The card ejector 550 includes an upper component 570 and a lower component 560, which are separated from each other but are mounted together by pivoting, and the two components can pivot relative to each other. The lower component 560 includes a top card portion 564, and a pair of first rotating shafts 562 are provided on both sides of the top card portion, which are main rotating shafts, and the first rotating shafts are pivoted to one end of the insulating body of the card edge connector. The upper component 570 includes a pair of vertical plates 574 spaced apart from each other, and a receiving groove 576 is formed between the vertical plates, and the receiving groove is used to press the PCI card received in the central slot. A pair of operating wings 579 are formed by protruding outward from the vertical plates horizontally. The upper component 570 includes a pair of second rotating shafts 571, which are auxiliary rotating shafts, and the second rotating shafts 571 are received in the rotating shaft holes provided inside the lower component 560, so that the upper and lower components are installed together through the second rotating shafts 571. The ejector 550 is provided with a notch between the lower surface 577 of the upper component and the upper surface 566 of the lower component, and the notch allows the upper component 570 to rotate at an angle of about 30 degrees on the lower component. In the process of ejecting the PCI card, a downward force is applied to the operating wing 579, and the upper component 570 first rotates outward with the second rotating shaft 571 as a fulcrum until the lower surface 577 of the upper component abuts against the upper surface 566 of the lower component, and then immediately presses the lower component 560 to rotate together with the second rotating shaft 562 as a fulcrum until the PCI card and the terminals in the insulating body are separated from each other. It can be understood that the initial rotation is mainly based on the second rotating shaft 571, and the second rotating shaft 571 is mainly arranged on the outside of the locking arm 572, so that the outward rotation path replaces the inward rotation path, which can avoid interference with the PCI card. If necessary, a spring can be set between the upper and lower components to make the two fit tightly.
