Description

Shield assembly and electrical connection device

The present invention relates to a shield assembly, and more particularly to a shield assembly for shielding an electrical connector and an electrical connection device having a shield assembly.

In some cases, the electrical connection device with the metal cage has a keyway extending from the mouth of the metal cage for docking for the docking connector having the key corresponding to the keyway. For example, Chinese Patent No. CN1929342A (U.S. Patent No. US2007054551) discloses an optical transceiver and a cage system in which a slot provided in a cage is equivalent to a keyway and a tab of its transceiver module is equivalent to a key. Design Patent No. DM101671, which is registered with the World Intellectual Property Organization ( WIPO ), discloses a socket connector having a grounding piece on the outer periphery of the adjacent opening of the cage, and the grounding piece is formed with a ridge structure corresponding to the key groove of the cage to form a passage. . The grounding strip is generally made of a metal sheet having a thickness of 0.1 mm. However, the strength of the raised structure of the single-layer metal sheet is insufficient, so that when the cage is assembled to a panel with the cornice facing forward, it is located at the cornice. The raised structure is easily deformed by accidentally hitting the panel, which in turn affects the docking of the socket connector and the docking connector.

Accordingly, it is an object of the present invention to provide a shield assembly that solves the aforementioned problems.

Thus, in some embodiments, the novel shield assembly includes a metal cage and a grounding member. The metal cage defines a mouthpiece and an accommodation space extending from the mouth in a pair of connection directions, and has a keyway extending from the mouth in the butting direction. The grounding member is disposed on the outer surface of the metal cage adjacent to the mouthpiece, and has a body connected to the metal cage, and a bend extending from the edge of the body to extend adjacent to the mouth And a plurality of resilient fingers extending from the bent portion, the body having a raised guiding cover corresponding to the keyway and defining a passage in communication with the keyway.

In some embodiments, the resilient fingers extend from the bend away from the rake.

In some embodiments, at least one of the resilient fingers is located on an outer surface of the guide cover.

In some embodiments, the body further has a back cover portion that connects the guide cover portion and covers the end of the channel opposite the one of the mouthpieces.

In some embodiments, the back cover has a shield section that covers the passage, and a bottom contact section that extends from the shield section and contacts the metal cage.

In some embodiments, the back cover portion further has at least one side contact segment that extends from the shielding segment and contacts the guiding cover portion.

In some embodiments, the metal cage has at least one positioning portion that protrudes outwardly, and the body further has at least one positioning hole corresponding to the at least one positioning portion.

Another object of the present invention is to provide an electrical connection device having the aforementioned shield assembly.

Thus, in some embodiments, the novel electrical connection device includes the aforementioned shield assembly and an electrical connector. The electrical connector is located in the accommodating space and has a slot facing the mortise and extending in the docking direction.

The novel has the following effects: the grounding member can be stamped and bent from a metal sheet, is easy to manufacture, and the guiding cover portion at the cornice has a double-layer metal sheet thickness by the bending portion, and the structure is relatively firm and difficult to be Deformed by collision.

The upper body 4A and the lower body 4B can be fixed to the metal cage 3 by, for example, laser spot welding or riveting. In addition, the metal cage 3 has two positioning portions 37 protruding outwardly, and the main body 41 further has two positioning holes 44 corresponding to the positioning portions 37 for the grounding member 4 and the metal cage. When the shell 3 is assembled, the grounding member 4 can be positioned opposite to the metal cage 3 for easy assembly. In a variant embodiment, the grounding member 4 can also be a one-piece frame shape, or the upper body 4A is U-shaped on the top wall 31 and the two side walls 33 of the metal cage 3 and the lower body 4B is provided. The position of the guiding cover portion 411 can be adjusted according to the position of the key groove 36, which is not limited to the embodiment.

Referring to FIG. 2, FIG. 6, and FIG. 7, the electrical connector 2 is located in the accommodating space 35 and has a slot 21 extending toward the port 34 and in the docking direction D for the docking. The electrical connections are docked to form an electrical connection.

Referring to FIGS. 8-11, a second embodiment of the present electrical connection device is substantially identical to the first embodiment, but in the second embodiment, three resilient fingers 43 are located on the outer surface of the guide cover portion 411 and The rear cover portion 412 has a shielding portion 412a covering the passage 411a, a bottom contact portion 412b bent from the shielding portion 412a and contacting the metal cage 3, and two bent and extending from the shielding portion 412a. The side contact section 412c of the guide cover portion 411 is contacted. In the second embodiment, the bottom contact portion 412b and the side contact portion 412c have better effects of preventing EMI leakage than the first embodiment.
