Description

Technical Field

[0001] The utility model relates to the field technology of backplane connectors, in particular to an insulating shielding sheet structure of a backplane connector. Background Art

[0002] With the rapid development of information technology and the increasing demand for data, the requirements for data transmission rates for large amounts of data are becoming higher and higher. High-speed connectors, including backplane connectors, board-to-board connectors, and I / O connectors, are also developing towards higher rates. To increase the transmission rate of the connector, it is necessary to ensure the signal quality at a higher frequency transmission rate. The quality of the signal on the transmission path is signal integrity, and the main indicators include crosstalk, loss, and impedance. In order to prevent the signal from being crosstalked by the outside, the backplane connector generally uses a shielding sheet to shield it.

[0003] The existing backplane connector shielding plates are all exposed on the outer surface of the backplane connector. Since the shielding plates are mostly conductive structures, the overall insulation of the backplane connector is poor. When multiple backplane connectors are used together, a certain space interval is required between two adjacent backplane connectors, resulting in a larger overall occupied space. The shielding plates are easily in contact with the outside, thereby affecting their signal shielding function. At the same time, the connection structure between the shielding plates and the insulating body will also make the overall appearance poorly integrated. Therefore, it is necessary to further improve the existing backplane connector structure. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a backplane connector insulating shielding sheet structure, which can effectively solve the problems of poor insulation of the existing backplane connectors, large space occupied when multiple are used, and poor shielding effect.

[0007] As a preferred solution, the insulating body is provided with a heat dissipation groove penetrating the upper and lower surfaces of the insulating body, and the terminal group passes through the heat dissipation groove.

[0008] As a preferred solution, the terminal group includes two terminals arranged at intervals, and correspondingly, two heat dissipation slots are also arranged at intervals, and each terminal passes through the corresponding heat dissipation slot.

[0009] As a preferred solution, a positioning hole that cooperates with the outside is integrally formed on the lower surface of the insulating body.

[0010] As a preferred solution, the lower surface of the cover plate is integrally provided with a recessed groove that cooperates with the shielding sheet, and the shielding sheet extends into the recessed groove.

[0011] As a preferred solution, a reinforcement portion is integrally extended outward from the upper surface of the insulating body, the upper surface of the reinforcement portion is flush with the upper surface of the cover plate, and one end of the terminal group extends outward from the insulating body through the reinforcement portion.

[0012] As a preferred solution, the number of the fixing columns is three and arranged at intervals in the transverse direction, and correspondingly, the number of the fixing holes is also three and arranged at intervals in the transverse direction, and each fixing column passes through the corresponding fixing hole.

[0013] As a preferred solution, the shielding sheet is provided with a through hole for the fixing column to pass through.
