[0044] To facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will be further described with reference to the accompanying drawings and specific embodiments.

[0045] The electrical connector of the present invention is used to accommodate a chip module to achieve electrical connection between the chip module and the circuit board. Figure 5-9 As shown, an electrical connector 100 is used to electrically connect a chip module 800 to a circuit board 900. The circuit board 900 has a first surface 91 and a second surface 92 (marked on the left) opposite to each other. Figure 2 The electrical connector 100 includes an electrical connection base 10, a fixing base 20, a cover plate 30 and a bottom plate 40 (see Figure 2 ), the electrical connection seat 10 is installed on the first surface 91 of the circuit board 900, used to accommodate and electrically connect the chip module 800, the fixing seat 20 is arranged on the first surface 91 of the circuit board 900 and is located on the periphery of the electrical connection seat 10, the cover plate 30 is pivotally connected to one end of the fixing seat 20, and the base plate 40 is installed on the second surface 92 of the circuit board 900. The key improvement of the present invention is that the electrical connector 100 further includes a plurality of matching first locking members 50, second locking members 60 and pressing members 70. The first locking member 50 passes through the base plate 40, the circuit board 900 and the fixing seat 20 and is exposed above the fixing seat 20. The second locking member 60 is provided on the cover plate 30. When the cover plate 30 is closed toward the electrical connection seat 10, the second locking member 60 is locked to the first locking member 50 so that the cover plate 30 presses against the chip module 800. The pressing member 70 is pressed on the first locking member 50 to fix the first locking member 50 to the fixing seat 20. That is, the pressing member 70 uses the lateral force of the pressing member 70 on the first locking member 50 so that the first locking member 50 preliminarily fixes the base plate 40 and the fixing seat 20 to the front and back surfaces of the circuit board 900, respectively.

[0046] The following first introduces the assembly process and steps of the electrical connector 100 , the circuit board 900 , and the chip module 800 of this embodiment.

[0047] Ginseng Figure 1As shown, a plastic grabbing auxiliary member 11 is fixed to the surface of the electrical connection base 10, and the electrical connection base 10 is placed on the first surface 91 of the circuit board 900;

[0048] Ginseng Figure 1-2 The base plate 40 is placed on the second surface 92 of the circuit board 900. Six bolts 51 extend through six through-holes 41 provided in the base plate 40 and the circuit board 900, respectively. The base plate 40 is made of a metal plate, with a plastic insulating layer 42 applied to its upper surface. The caps 511 of the bolts 51 are located within the through-holes 41 of the base plate, while the studs 512 extend upward through the circuit board 900, exposed above the first surface 91 of the circuit board.

[0049] Ginseng Figure 3-4 After assembling the cover plate 30 and the fixing plate 20 together, they are then mounted from top to bottom on the first surface 91 of the circuit board 900. One end of the cover plate 30 is mounted to one end of the fixing base 20 via a pivoting member 31a. The pressing member 70 is fixed to the upper surface of the fixing base 20 and is located between the fixing base 20 and the cover plate 30. At this time, a dust cover 32 can be first mounted on the upper surface of the cover plate 30, covering the central opening, and then assembled together to the circuit board 900. The dust cover 32 can also be assembled after the cover plate 30 and the fixing base 20 are mounted on the circuit board 900. When the cover plate 30 and the fixing base 20 are placed on the first surface 91 of the circuit board, the first locking member 50 passes through the pressing member 70 and is locked to the second locking member 60, facilitating the subsequent soldering process, that is, soldering the pins of the conductive terminals of the electrical connection base to the circuit board. Please note that the above is the process in which the electrical connector manufacturer provides the electrical connector 100 to the system manufacturer before the electrical connector is soldered to the circuit board. Generally, the second locking member 60 is further rotated and fixed to the first locking member 50 using a tool, such as a screwdriver, to prevent damage to the electrical connector socket 10 caused by shaking during transportation.

[0050] Ginseng Figure 4-6 When the chip module 800 needs to be loaded, the second locking member 60 is rotated to release the second locking member 60 and the cover 30 is rotated upward to open the cover. Figure 5 It can be seen from the partially enlarged view that the pressing part 70 is located on the upper surface of the fixing seat 20, and its lateral elasticity presses against the first locking part 50 to ensure that the first locking part 50 will not loosen, so that the base plate 40 will not fall off from the second surface 92 of the circuit board 900. Then, remove the grasping auxiliary part 11 to expose the electrical connection seat 10, and then install the chip module into the electrical connection seat 10. Please note that in this embodiment, the electrical connection seat 10 includes conductive terminals in a matrix shape and an insulator that carries the conductive terminals. A chip receiving space is formed above the insulating seat. Since the conductive terminals are a conventional structure, they are not shown in the figure. The fixing seat 20 surrounds the insulator. It is worth noting that the chip module 800 of this embodiment is installed to the electrical connection seat 10 through the transfer member 81. Figure 7 shown.

[0051] Continue to participate Figure 9 , rotate the cover 30 to the electrical connection seat 10, further rotate the second locking member 60 to stably lock it with the first locking member 50, and the cover 30 is also pressed against the upper surface of the chip module 800.

[0052] The detailed structure is introduced below.

[0053] Ginseng Figure 11-12 The fixing seat 20 is a metal plate frame having a front end 201, a rear end 202 and a side 203 connecting the front and rear ends. The front end 201 is fixed with a cover plate rotating mechanism 21. The cover plate rotating mechanism 21 includes a pair of supporting plates 211, a pivot 212 passing through the supporting plates 211, and a pair of coupling plates 31 extending from the front end of the cover plate. The coupling plates 31 are sleeved on the pivot 212 and can rotate around the pivot. In this way, the cover plate 30 can rotate around the pivot 212, combined with Figure 3 Each support plate is bent forward to form a blocking piece 214, which prevents the coupling piece 31 from disengaging from the pivot shaft. A gasket 215 is sleeved on one end of the pivot shaft. The cover plate 30 and the cover plate rotation mechanism 21 of the fixed base form the aforementioned pivot member 31a. The bottom surface of the fixed base is covered with an insulating layer 24 made of plastic.

[0054] The module rotation mechanism 22 is fixed to the rear end 202 of the fixing base 20. The fixing base 20 is bent at its rear end to form a support piece 221 extending upward. Each support piece is in an inverted L shape and opens forward. A rotating frame 222 has a receiving slot 2210 open to one side, and a pivot 223 and a spring 224 are installed on the other side. The pivot 223 is assembled into the support piece 221 from the open side. After the chip module 800 is assembled into the transfer unit 81, Figure 7-8 One end 811 of the transfer member 81 is inserted into the receiving groove 2210 , and then the rotating frame 222 is rotated so that the chip module 800 and the transfer member 81 are assembled into the electrical connection seat 10 together.

[0055] The fixing seat 20 is provided with a through hole 23 at the junction of its side 203 and the front and rear ends, and a through hole 23 is provided in the middle of the side, so that a total of six through holes 23 are formed. The six pressing pieces 70 are respectively provided at the corresponding through holes 23. Figure 6 、 Figure 10 The pressing member 70 is a metal plate fixed to the upper surface of the fixing base 10 by spot welding. The pressing member 70 has a through-hole 71 and a plurality of elastic arms 72 extending into the through-hole. The through-hole 71 allows the first locking member 50 to pass through. The elastic arms 72 elastically press against the periphery of the first locking member to provide a retaining force and prevent the first locking member from falling off. Each pressing member is provided with two pairs of opposing elastic arms. The ends of the elastic arms are bent to form a plate surface 722 that presses against the first locking member.

[0056] Combine Figure 2 、 6 The first locking member 50 is a bolt 51 having an outer peripheral thread, and the end of the elastic arm 722 of the pressing member is pressed against the outer peripheral thread. The second locking member 60 includes a nut 61 and a collar 62 that pass through the cover plate 30 from top to bottom. The nut has an inner peripheral thread, and the collar 62 is sleeved on the outer periphery of the end of the nut 61 below the cover plate 30. The threaded column of the bolt 51 enters the inner periphery of the nut 61, and then the top surface of the nut 61 is rotated using a tool so that the bolt 51 and the nut 61 are locked to each other. The collar 62 is sleeved on the outer peripheral lower end of the nut so that the nut will not fall off the cover plate 30. At the same time, when the nut is rotated downward to reinforce, the collar and the nut jointly press the elastic arm downward.

[0057] The base plate 40 of the present invention is preliminarily fixed to the fixing base 20 by the pressing piece 70 on the base 20 through a simple pressing operation, while omitting the nut for installing the fixing base.

[0058] The assembly method described above is only one embodiment. However, in other embodiments, there may be no gripping auxiliary member 11, dust cover, etc. The following is a summary of the assembly method of the present invention:

[0059] Step 1: Provide an electrical connection base 10 and install the electrical connection base 10 on the front surface (i.e., the first surface 91) of the circuit board 900;

[0060] Step 2: Provide a base plate 40 and a plurality of first locking members 50. The base plate 20 is placed on the back side (i.e., the second surface 92) of the circuit board. The first locking members 50 pass through the base plate 20 and the circuit board 900.

[0061] Step 3: Provide a cover plate 30 and a fixing base 20. The cover plate 30 is installed with a plurality of second locking members 60. The fixing base 20 is installed with a plurality of pressing members 70. The cover plate is pivotally connected to one end of the fixing base.

[0062] Step 4: Install the cover 30 and the fixing seat 20 installed in step 3 to the front side 91 of the circuit board. The first locking member 50 passes through the pressing member 70 and cooperates with the second locking member 60. The pressing member 70 presses the first locking member 50 to achieve a preliminary fixation of the first locking member 70 and the fixing seat 20. When the cover 30 is closed toward the electrical connection seat 10, the second locking member 60 is locked to the first locking member 50.

[0063] The above are only preferred embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and the content of the present invention should still fall within the scope of the present invention.
