[0040] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0041] The following will be combined Figures 1 to 8 The specific implementation of the electrical connector assembly, the electrical connector and the locking assembly thereof of the present invention is introduced.

[0042] like Figures 1 to 8 As shown, the present invention provides an electrical connector assembly 1000 for electrically connecting to a circuit board (not shown), the electrical connector assembly 1000 includes a chip module 100 and an electrical connector 200, the electrical connector 200 includes a base body 1 and a plurality of terminals 2 arranged in a matrix on the base body 1, the base body 1 is provided with a receiving space 10 for receiving the chip module 100, the terminal 2 includes a contact portion 20 protruding into the receiving space 10 to dock with the chip module 100, a first locking member 101 is installed on the outer side of the chip module 100, and a second locking member 201 is installed on the outer side of the base body 1, and when the chip module 100 is placed in the electrical connector 200, the second locking member 201 holds the first locking member 101. When the contact portion 20 contacts the chip module 100, a positive force facing the chip module 100 is generated, that is, the positive force exerted when the contact portion 20 is deformed; in this way, when the electrical connector assembly 1000 is provided with a large number of terminals 2, the locking force between the first and second locking members 101 and 201 can effectively overcome the above-mentioned upward positive force generated by the large number of terminals 2 when the chip module is pressed down, thereby providing load force for the assembly of the chip module 100, which meets the requirement that today's electrical connector assembly needs to be provided with a large number of terminals to transmit high-speed signals.

[0043] The first locking member 101 and the second locking member 201 constitute the locking assembly 300 of the present invention. Figures 2 to 8As shown, the second locking member 201 is provided with a plurality of upwardly bent hooks 202, which protrude into the receiving space 10. The first locking member 101 is provided with a plurality of downwardly extending extension pieces 102 corresponding to the hooks 202, and the extension pieces 102 are provided with hook holes 1020. During assembly, the chip module 100 is first lowered onto the electrical connector 200, and then the chip module 100 is moved horizontally and laterally in a first direction to push the extension pieces 102 toward the hooks 202, thereby allowing the hooks 202 to pass through the hook holes 1020 and finally hook into the hook holes 1020. Therefore, the present invention can achieve the goal of simultaneously locking the first and second locking members 101 and 201 together to alleviate the aforementioned positive force when the chip module 100 is installed in the receiving space 10. After the chip module 100 is assembled into the receiving space 10, it needs to press downward against the terminal contact portion 20. Therefore, the chip module 100 will be pushed upward due to the upward positive force exerted by the terminals 1. The locking effect generated by the first and second locking members 101 and 201 can help alleviate the positive force exerted by the large number of terminals 1, which not only improves the retention effect but also makes the operation very convenient and simple. If the chip module 100 needs to be removed from the electrical connector 200, it is only necessary to first press the chip module 100 downward and then push it in a second direction opposite to the first direction.

[0044] See Figures 6 and 7 The second locking member 201 is formed by bending a metal plate and includes a second covering portion 203 that at least partially covers the base 1. The hook portion 202 is bent and extended from the second covering portion 203. The second covering portion 203 includes a second fitting portion 204 located on the upper surface of the base 1. All the hook portions 202 extend in the same direction. Specifically, the hook portion 202 is bent and extended upward from the second fitting portion 204 along the second direction opposite to the first direction. Figure 2 and Figure 4, the second locking member 201 is provided with multiple rows of hooks 202, and at least one row of hooks 202 is located between two different matrices of the terminals 1. At least two rows of hooks 202 are respectively located on the opposite outer sides of the terminal matrices. Such an arrangement can make the seat body 1 bear the force evenly and can effectively reduce the warping of the center of the seat body 1. In this embodiment, the second fitting portion 204 is arranged in an "I" shape, and the second fitting portion 204 includes a second edge portion 2041 located at two opposite edges of the receiving space 10 and a second middle portion 2042 spanning the receiving space 10 and connecting the two second edge portions 2041. The hooks 202 are arranged in three rows and match the above-mentioned "I" shape, that is, the hooks 202 are arranged at the second edge portion 2041 and the second middle portion 2042. The second covering portion 203 also includes a second locking portion 205 extending from the second edge portion 2041, and the second locking portion 205 covers the side and bottom surfaces of the base body 1, thereby cooperating with the second edge portion 2041 to clamp the second locking member 201 to the base body 1 in the thickness direction of the base body 1.

[0045] like Figures 2 to 7 As shown, the first locking member 101 is formed by bending a metal plate and includes a first covering portion 103 that at least partially covers the chip module 100. The extension piece 102 is bent and extends from the first covering portion 103. The first covering portion 103 is provided with a first affixed portion 104 that affixes to the bottom surface of the chip module 100. Specifically, the extension piece 102 bends and extends downward from the first affixed portion 104 along the first direction. In this embodiment, the first and second affixed portions 104 and 204 are arranged correspondingly. The first affixed portion 104 is arranged in an "I" shape and includes first edge portions 1041 located at two opposite edges of the chip module 100 and a first middle portion 1042 that spans the chip module 100 and connects the two first edge portions 1041. The extension pieces 102 are arranged in three rows, matching the "I" shape, that is, the extension pieces 102 are arranged at the first edge portion 1041 and the first middle portion 1042. The first covering portion 103 also includes a first locking portion 105 extending from the first edge portion 1041, and the first locking portion 105 covers the side and top surfaces of the chip module 100, thereby cooperating with the first edge portion 1041 to clamp the first locking member 101 to the chip module 100 in the thickness direction of the chip module 100.

[0046] In this embodiment, the first and second locking members 101 and 201 are both made of iron. The iron-clad structure of the locking assembly 300 can disperse stress and effectively reduce the risk of breakage of the locking assembly 300. In other embodiments, a second terminal similar to the hook 202 can be inserted into the base 1 to replace the hook 202 and cooperate with the extension piece 102, thereby achieving a secure assembly between the chip module and the electrical connector.

[0047] The present invention can effectively overcome the upward positive force generated by the larger number of terminals 1 when the chip module 100 is pressed down through the locking force between the first and second locking parts 101 and 102, thereby providing a load force for the assembly of the chip module 100 and the electrical connector 100, which is conducive to setting a larger number of terminals 1 on the electrical connector combination 1000, meeting the requirements of the electrical connector for transmitting high-speed signals; at the same time, the present invention not only sets a hook portion 202 on the periphery of the terminal 1, but also sets a hook portion in the middle of the terminal matrix, so that the seat body 1 is evenly stressed and the warping of the center of the seat body 1 can be effectively reduced; in addition, the chip module 100 of the present invention only needs to be pushed horizontally after being pressed down to achieve the mutual locking of the hook portion 202 and the hook hole 1020 in the locking component 300, thereby completing the assembly, and the operation is simple and convenient.
