The plurality of positioning portions 52 extend downwardly from the main body 51 and surround the through hole 511. There are four positioning portions 52, which are substantially disposed at adjacent outer positions corresponding to the four corners of the through hole 511. The positioning portions 52 are substantially in the shape of an "L". Each of the guide portions 53 is provided with a guide hole 531 extending upward and downward, and the clamping member 5 is further provided with an action portion 54 connected between the guide portion 53 and the main body portion 51. The action portion 54 is arranged higher than the guide portion 53, and the action portion 54 is located above the positioning portion 52. The clamping member 5 also includes a plurality of buckle portions 55 protruding downward relative to the main body portion 51. Specifically, the action portion 54 is located between the corresponding guide portion 53 and the adjacent positioning portion 52. The plurality of buckle portions 55 extend downward from the main body portion 51 to form and surround the through hole 511. The plurality of buckle portions 55 are arranged on the front and rear sides and the left and right sides of the through hole 511.
[0046] like Figure 1 As shown, the chip module 300 includes a substrate 6 and a protrusion 7 protruding upward from the substrate 6 .
[0047] like Figure 1 and Figure 6 As shown, when the electrical connector 1 is not loaded with the chip module 300, the accommodating cavity 1B is exposed to the window 22, and the opening 31 is arranged corresponding to the window 22 up and down, and the second pivot portion 32 is pivoted to the first pivot portion 24, so that the pressure cover 3 can rotate around the first pivot portion 24, and at the same time, the dust cover 4 is fastened to the bottom of the pressure cover 3 by the fastening portion 422, and the cover body 41 is covered on the opening 31. The dust cover 4 is covered on the top of the accommodating cavity 1B along with the pressure cover 3, which can prevent dust and other debris from entering the insulating body 1A and avoid contaminating the conductive terminals (not shown).
[0048] like Figure 1 , Figure 4 and Figure 5As shown, the chip module 300 is installed on the clamping member 5. At this time, the substrate 6 is located below the main body 51, and the plurality of snap portions 55 are snapped on the bottom of the substrate 6. The protrusion 7 is exposed above the clamping member 5 through the through hole 511, and part of the main body 51 is located directly above the substrate 6 along the four sides of the through hole 511. In this way, the substrate 6 is limited in the up and down directions by the main body 51 and the snap portions 55.
[0049] like Figure 7 and Figure 8 As shown, when the dust cover 4 rotates with the pressure cover 3 around the fixing seat 2 away from the insulating body 1A, the clamp 5 carries the chip module 300 and is vertically installed on the insulating body 1A along the up-down direction, and the guide column 23 vertically passes through the guide hole 531 along the up-down direction, so as to facilitate the initial positioning of the clamp 5 when it is assembled on the top of the fixing seat 2. The plurality of positioning portions 52 protrude downward into the window 22 and are positioned on the periphery of the insulating body 1A, so as to realize the precise positioning of the clamp 5 on the electrical connector 1, so that the chip module 300 and the plurality of conductive terminals (not shown) are precisely positioned.
[0050] like Fig. 9 , Fig.10 and Fig.11 As shown, when the chip module 300 is loaded into the accommodating cavity 1B and the pressure cover 3 is not rotated to cover, the clamping member 5 is located above the fixing seat 2. Since the chip module 300 is supported by the conductive terminal (not shown), part of the main body 51 is located directly above the substrate 6 along the four sides of the through hole 511, so that the clamping member 5 is supported by the chip module 300, so that the guide portion 53 is located above the bottom plate 21 of the fixing seat 2 and the two are spaced apart. In addition, the bottom surface of the main body 51 is higher than the bottom surface of the guide portion 53 in the up and down direction.
[0051] like Fig.10 , Fig.11 and Fig.13As shown, when the dust cover 4 rotates with the pressure cover 3 to cover the insulating body 1A, the ejection portion 42 begins to squeeze the action portion 54 downward in the up-down direction, thereby driving the guide portion 53 connected to the action portion 54 to move downward, and also driving the chip module 300 to press the conductive terminal downward until the guide portion 53 contacts the bottom plate 21 of the fixing seat 2. In this way, the fixing seat 2 supports the guide portion 53 upward to provide support force for the guide portion 53. The guide portion 53 also supports the action portion 54 upward to provide sufficient reverse force for the action portion 54 to push the action portion 54, so that the retaining portion 422 can be disengaged from the retaining of the pressure cover 3, and then the dust cover 4 is detached from the connector assembly. When viewed from a top view, the ejection portion 42 falls downward into the range of the corresponding action portion 54 (auxiliary reference Fig.14 ), so as to ensure that the ejection portion 42 is evenly pushed by the action portion 54, so that the ejection portion 42 can be completely pushed by the action portion 54. In this embodiment, the ejection portion 42 is pushed upward by the clamping member 5 at a portion other than the guide portion 53. Of course, in other embodiments, the ejection portion 42 can also be pushed upward by the guide portion 53. After the chip module 300 is loaded into the receiving cavity 1B and the pressure cover 3 is not rotated to cover, the guide portion 53 can directly contact the bottom plate 21 of the fixing seat 2.
[0052] In summary, the connector assembly has the following beneficial effects:
[0053] (1) Compared with the prior art, the present invention uses the clamping member 5 to push the ejection portion 42 of the dust cover 4 to separate the dust cover 4 from the connector assembly, thereby avoiding the risk of damaging the chip module 300 by using the chip module 300 to push the dust cover 4, and also improving the assembly efficiency.
[0054] (2) The guide portion 53 is in contact with the bottom plate 21 of the fixing seat 2, and the fixing seat 2 supports the guide portion 53 upward to provide a supporting force for the guide portion 53. The guide portion 53 also supports the action portion 54 upward to provide the action portion 54 with sufficient reverse action force for pushing the action portion 54, thereby enhancing the structural strength of the action portion 54.
[0055] (3) The contact surface 421 is provided with a notch 423 on opposite sides of the latching portion 422 , respectively. The notch 423 extends in the up-down direction to facilitate injection molding of the latching portion 422 .
[0056] (4) When viewed from above, the ejection portion 42 falls downward into the action range of the corresponding action portion 54, thereby ensuring that the ejection portion 42 is evenly pushed by the action portion 54, so that the ejection portion 42 can be completely pushed by the action portion 54, and also ensuring that the ejection portion 42 is not partially ejected and damaged, so that the dust cover 4 can be recycled.
[0057] (5) The bottom surface of the main body 51 is arranged higher than the bottom surface of the guide portion 53 in the up and down direction, so that the bottom surface of the guide portion 53 is positioned on the fixing seat 2 as a reference surface, which can prevent the clamping member 5 from forming a relatively large plane as a reference surface during injection molding, and its flatness is difficult to ensure.
[0058] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
