This patent application claims priority of a Chinese Patent Application No. 202121801823.6, filed on Aug. 3, 2021 and titled “CONNECTOR ASSEMBLY”, the entire content of which is incorporated herein by reference.
The present disclosure relates to a connector assembly, which belongs to a technical field of connectors.
Some electrical systems often use orthogonal connectors to interconnect two circuit boards with each other. In some applications, the circuit boards are oriented orthogonal to each other. Typically, the orthogonal connector include a first connector mounted on a first circuit board and a second connector mounted on a second circuit board. The first connector and the second connector are matched and connected to realize the connection between the first circuit board and the second circuit board. The first circuit board and the second circuit board are disposed perpendicular to each other. However, the existing orthogonal connector occupies a relatively large space, resulting in low space utilization in the electrical system.
An object of the present disclosure is to provide a connector assembly with higher space utilization.
In order to achieve the above object, the present disclosure adopts the following technical solution: a connector assembly, including: a card connector including a first terminal module, a second terminal module and a circuit board card, the circuit board card being connected to the first terminal module and the second terminal module so as to jointly form a receiving cavity; and a first backplane connector received in the receiving cavity.
In order to achieve the above object, the present disclosure adopts the following technical solution: a connector assembly, including: a card connector including a first terminal module, a second terminal module parallel to the first terminal module, and a circuit board card erected on the first terminal module and the second terminal module; the first terminal module and the second terminal module being electrically connected to the circuit board card; the first terminal module, the second terminal module and the circuit board card jointly forming a receiving cavity; a first backplane connector received in the receiving cavity.
Compared with the prior art, the first terminal module and the second terminal module of the present disclosure are lapped with the circuit board to form a receiving cavity, and the first backplane connector is received in the receiving cavity. As a result, it can make full use of space to improve space utilization of the connector assembly.

The second terminal module 12 includes a plate-shaped second insulating portion 121 and a plurality of second pressing terminals 122 fixed in the second insulating portion 121. In this embodiment, the second insulating portion 121 is molded together with the second press terminals 122 by injection molding. In other embodiments, the second pressing terminal 122 may also be fixed in the second insulating portion 121 in a post-assembly manner. After the card connector 1 is assembled on the first circuit board S1, the second insulating portion 121 is vertically arranged relative to the first circuit board S1. The second insulating portion 121 includes a second bottom end 1211 contacting the first circuit board S1 and a second top end 1212 disposed opposite to the second bottom end 1211. Each second pressing terminal 122 includes a second bottom pressing pin 1221 protruding beyond the second bottom end 1211 and a second top pressing pin 1222 protruding beyond the second top end 1212. In this embodiment, the second bottom pressing pins 1221 are pressed into corresponding connection holes (not shown) of the first circuit board S1. The second top pressing pins 1222 are pressed into the second holes 132 of the circuit board card 13. Each of the second bottom pressing pins 1221 and the second top pressing pins 1222 includes a fish-eye structure. The second bottom pressing pins 1221 and the second top pressing pins 1222 are pressed into the corresponding holes of the second circuit board S2 and the circuit board card 13 through the fish-eye structures. In this embodiment, the first bottom pressing pins 1121 and the second bottom pressing pins 1221 are inserted into the first circuit board S1 by pressing. The electrical connection is achieved by the first bottom pressing pins 1121 and the second bottom pressing pins 1221 elastically contacting the first circuit board S1. In other embodiments, welding can also be used for electrical connection.
In some embodiments, a plurality of first grooves 1113 are respectively provided on opposite sides of the first insulating portion 111. The first grooves 1113 on the opposite sides are symmetrically arranged. Correspondingly, a plurality of second grooves 1213 are respectively provided on opposite sides of the second insulating portion 121. The second grooves 1213 on the opposite sides are symmetrically arranged. In some embodiments, parts of the first pressing terminals 112 are exposed from the first grooves 1113. Parts of the second pressing terminals 122 are exposed from the second grooves 1213.
The card connector 1 also includes an inverted L-shaped bracket 15. The bracket 15 includes a rear wall 151 and a top wall 152 extending from an end of the rear wall 151. The rear wall 151 and the top wall 152 are perpendicular to each other. When the card connector 1 is mounted on the first circuit board S1, the rear wall 151 is vertically mounted on the first circuit board S 1, and the top wall 152 is suspended in parallel to the first circuit board S1. The first terminal module 11 and the second terminal module 12 are disposed on opposite sides of the bracket 15. The top wall 152 includes at least one positioning post 1521 protruding from a top surface of the top wall 152 for positioning the circuit board card 13. In this way, the first terminal module 11, the second terminal module 12, the circuit board card 13 and the bracket 15 are enclosed with the first circuit board S1 to form a receiving cavity 14. A plurality of first holes 131 and a plurality of second holes 132 are opened on opposite sides of the circuit board card 13, respectively. The circuit board card 13 defines at least one positioning hole 133 corresponding to the positioning post 1521, and the positioning post 1521 is inserted into the positioning hole 133. In this embodiment, the circuit board card 131 defines two positioning holes 133 at intervals. Correspondingly, the top wall 152 includes two protruding positioning posts 1521. An end of the circuit board card 131 is configured as a plug-in end 134. Specifically, the circuit board card 131 is installed on the top wall 152 and protrudes beyond the top wall 152 toward an end of an opening of the receiving cavity 14 to be set as a plug-in end 134. A plurality of conductive pads 1341 are arranged on upper and lower sides of the plug-in end 134, respectively. The conductive pads 1341 are used to realize electrical connection with the plug-in card connector 2.
