In the description of the present application, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, a fixed connection, a detachable connection, an interference connection, or an integral connection. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art in a specific context.

Fig. 1 is a front view of a connector assembly according to a first embodiment of the present disclosure. Fig. 2 is a left side view of the connector assembly of fig. 1. As shown in fig. 1 and 2, the connector assembly includes a metal housing 1 and a connector 2. The metal case 1 is provided with a ground portion for grounding. An accommodating chamber P is provided in the metal case 1, and the accommodating chamber P has a first opening P1 and a second opening P2. A connector 2 is disposed in the accommodation chamber P, the connector 2 having a first connection end D1 and a second connection end D2; the first connecting end D1 faces the first opening P1, and the second connecting end D2 faces the second opening P2. When the connector assembly is mounted to the single board, the first opening P1 of the metal case 1 faces the circuit board of the single board, so that the first connection end D1 of the connector 2 can be connected with the circuit board of the single board. When the single board mounted with the connector assembly is connected with the back board, the second open P2 of the metal case 1 may face the back board, so that the second connection end D2 of the connector 2 can be connected with the back board.

In the above technical solution, since the connector 2 is disposed in the accommodating chamber P of the metal shell 1, the connector 2 can be well prevented from being bumped during the mounting and dismounting process. In addition, the metal shell 1 is provided with the grounding part, so that the grounding part can play a role in shielding electromagnetic interference in use, specifically, external electromagnetic waves can be prevented from influencing the connector 2 in the metal shell 1, the radiation intensity of the connector 2 to the outside is reduced, the electromagnetic radiation energy loss is reduced, and meanwhile, the interference to other circuits in a system for installing the connector assembly is also avoided.

Fig. 3 is a top view of the connector assembly of fig. 1. As shown in fig. 1 and 3, the receiving chamber P optionally has a third opening P3. The third opening P3 is for heat dissipation.

Optionally, in order to facilitate accurate and quick connection of the metal shell 1 with other components, as shown in fig. 1, a guide structure G is provided on the metal shell 1. Wherein, the guiding structure G can be a groove or a cylinder. Further, the guide structure G may be disposed at the second opening P2. Thus, when the metal shell 1 is connected with the back plate, the guide structure G can be matched with the positioning structure arranged on the back plate to realize guiding. Or, when the metal shell 1 is connected with the line end connector, the guide structure G can be matched with a positioning structure arranged on the line end connector to realize guiding. In addition, in order to prevent the side of the connector 2 facing the second opening P2 from being hit by a component such as a back plate, at least a portion of the second opening P2 of the metal housing 1 may be disposed to protrude out of the connector 2. At this time, the guiding structure G may be disposed on the protruding portion of the second opening P2, so that when the single board on which the connector assembly is mounted is connected to the back board, the guiding structure G may be in contact with the positioning structure on the back board for the metal shell 1 to move to a desired position according to the guiding direction, thereby achieving a better guiding effect.

As shown in fig. 1 to 3, in the connector assembly provided in the first embodiment, the metal housing 1 may include a top wall T and a first side wall C1 and a second side wall C2 vertically connected to the top wall T, the first side wall C1 and the second side wall C2 are vertically disposed, an end surface of each of the first side wall C1 and the second side wall C2, which is far from the top wall T, forms a first opening P1, an end surface of each of the top wall T and the first side wall C1, which is far from the second side wall C2, forms a second opening P2, and an end surface of each of the top wall T and the second side wall C2, which is far from the first side wall C1, forms a third opening P3. The connector 2 can be surrounded from three sides by the metal shell 1, so that the connector 2 can be well prevented from being collided and shielded from electromagnetic interference in three directions.

Optionally, the side of the first side wall C1 and/or the top wall T remote from the second side wall C2 may be disposed to extend beyond the connector 2. As shown in fig. 2 and 3, the side of the first side wall C1 remote from the second side wall C2 is disposed to protrude out of the connector 2. At this time, the guide structure G may be provided on the protruding portion of the first sidewall C1, as shown in fig. 1.

In addition, when the connector 2 includes the first connector 21 and the second connector 22, the first connector 21 and the second connector 22 may be stacked within the accommodation chamber P. Thus, when the connectors 2 are arranged on the single board, if the total width of the connectors is greater than the width of the single board, the connectors 2 will overlap when placed side by side on the single board, which is not favorable for the connectors 2 to connect with other components, and cannot ensure the size of the heat dissipation channel with sufficient width; or in order to ensure the size of the heat dissipation channel with a sufficient width, the width of part of the connector needs to be compressed as much as possible, which causes the use type of the connector to be limited, and the working requirements under more use scenes cannot be met. By stacking the first connector 21 and the second connector 22 in the accommodating chamber P, the total width of the plurality of connectors 2 on a member such as a single board can be reduced, so that not only can the size of the heat dissipation passage of a sufficient width be ensured, but also the width of each connector 2 does not need to be reduced, and the connectors 2 can be conveniently connected with another device in a manner of being arranged.

Optionally, the first connector 21 is suspended on the metal housing 1 in order to secure the installation of the first connector 21 and/or to avoid the gravity of the first connector 21 from being exerted on the second connector 22.

Specifically, as shown in fig. 1, the first connector 21 may be provided with a clamping portion 211, the inner surface of the metal shell 1 may be provided with a clamping groove 11, and the clamping groove 11 extends to the second opening P2, so that the clamping portion 211 can slide into the clamping groove 11 from the second opening P2. The card slot 11 may include two rectangular slot bodies stacked and communicated with each other, and the cross-sectional area of the rectangular slot body located above is larger than that of the rectangular slot body located below, so that the engaging portion 211 can be engaged with and mounted in the card slot 11. Alternatively, the slots may be dovetail slots.

As shown in fig. 2, when the first connector 21 is L-shaped, the first connection end D1 is an end of a first side of the L-shaped first connector 21, the second connection end D2 is an end of a second side of the L-shaped first connector 21, and the first and second sides of the first connector 21 are disposed around the second connector 22. That is, a space is left below the first connector 21, the second connector 22 can be arranged, the three-dimensional space is fully utilized, and the width dimension of the connector assembly is reduced, so that the connector assembly occupies a smaller width dimension of the printed circuit board. This allows more space on the circuit board for other uses, such as increasing the size of the heat dissipation gap between adjacent connector assemblies to improve heat dissipation, or increasing the number of connectors to increase the number of signals between circuit boards.

Wherein one of the first connector 21 and the second connector 22 is a power connector and the other is a signal connector. Alternatively, the first connector 21 and the second connector 22 are both signal connectors.

The metal shell 1 can surround the connector 2 from four sides, so that the connector 2 can be well prevented from being collided and shielded from electromagnetic interference in four directions.

In the connector assemblies provided in the second and third embodiments of the present application, in order to prevent the second connection end D2 of the connector 2 from colliding against the connector 2 when being connected to a component such as a back panel or a line terminal connector through the second opening P2, in some embodiments, an end surface of at least one of the top wall T, the first side wall C1, and the third side wall C3 forming the second opening P2 is disposed to protrude out of the connector 2.
