Description

Technical Field

[0001] The present invention relates to the technical field of conductive connection, and particularly relates to a female terminal connector and a connector assembly. Background Art

[0002] The connection between cables is usually achieved by the insertion and interconnection of a male terminal connector and a female terminal connector. To ensure high-speed transmission performance, a shielding structure is provided around the contact members of both the male terminal connector and the female terminal connector, and the shielding is electrically connected after the male terminal connector and the female terminal connector are inserted and connected. For the existing insertion connection structure of the male terminal connector and the female terminal connector, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , a female terminal cable 3 is connected to the female terminal connector 1, a male terminal cable 4 is connected to the male terminal connector 2, the male terminal connector and the female terminal connector are inserted and connected to form a connector assembly. The female terminal connector 1 includes a female terminal shield and female terminal contact members 14. A plurality of pairs of female terminal contact members are arranged side by side in the left-right direction, and each pair of female terminal contact members forms a differential pair to transmit differential signals. The female terminal shield includes a female upper shield 11, a female lower shield 15, and a female side shield 12 disposed around each pair of female terminal contact members. There are female side shields on both the left and right sides of the female terminal contact members. The two left and right female side shields, and the corresponding female upper shield and female lower shield are used to enclose a rectangular female insertion cavity. The female upper shield is used to form the upper cavity wall of the female insertion cavity. The rear end of each female insertion cavity is provided with a socket. A support body 13 is provided in the female insertion cavity, and the female terminal contact members 14 are inserted through the support body 13 and extend into the female insertion cavity; the male terminal connector 2 includes a male terminal shield and male terminal contact members. The male terminal contact members are arranged in pairs. The male terminal shield includes a male upper shield 21, a male lower shield, and a male side shield 22 disposed around each pair of male terminal contact members. There are male side shields on both the left and right sides of the male terminal contact members. The two left and right male side shields, and the corresponding male upper shield and male lower shield are used to enclose a male insertion cavity. The front end of the male insertion cavity is provided with a socket. The male terminal contact members extend into the female insertion cavity; when the male terminal connector and the female terminal connector are inserted, the male terminal shield is inserted into the female insertion cavity, the front part of the male insertion cavity enters the female insertion cavity, and the female terminal contact members extending into the female insertion cavity are inserted into the male insertion cavity to contact and conduct with the male terminal contact members. A side shield spring piece 121 is provided on the inner side surface of the female side shield to contact the outer side surface of the male side shield after the male terminal shield is inserted to achieve shielding conduction.

[0003] However, there is still a problem of insufficient shielding in the mating area when the existing shielding structure is actually applied. To ensure smooth mating, a gap is left between the male-end shield and the cavity wall of the female-end mating cavity to prevent the male-end shield from being blocked during insertion. The contact and conduction position between the male-end shield and the female-end shield is only at the side shielding elastic pieces, that is, the shielding contact and conduction are only achieved on the left and right sides of the contact member. At the upper and lower sides, the female-end shield and the male-end shield do not contact. The crosstalk signals on the upper or lower side need to be first conducted to the side shielding elastic piece positions on the left and right sides and then conducted away. The conduction path is relatively long, and resonance will occur during high-speed signal transmission. Therefore, the shielding structure needs to be further improved to improve the high-speed transmission performance. Summary of the Invention

[0004] The object of the present invention is to provide a female-end connector to solve the problem of insufficient shielding of the existing female-end connector; the object of the present invention is also to provide a connector assembly to solve the problem of insufficient shielding after the connection between the existing female-end connector and the male-end connector.
