Description

Technical Field

[0001] The present invention provides a shielding structure for an electrical connector, particularly a shielding structure for an electrical connector that can effectively reduce electromagnetic interference between terminals. Background Art

[0002] Generally speaking, most electronic devices transmit signals or currents through accessories such as sockets or wires. During the transmission, an electromagnetic field will be generated along with the current or voltage. This electromagnetic field will cause interference, thereby reducing the performance of the electronic device or generating incorrect signals. This is the so-called electromagnetic interference (EMI). When some devices are larger or carry more current, the generated electromagnetic interference will be more serious, even affecting human health.

[0003] With the progress of the times, many electronic devices are becoming more and more miniaturized. However, during the miniaturization process, it is also required to enhance the transmission effect of various signals or currents. Therefore, during the miniaturization process, various terminals and wires are getting closer and closer to each other, and the signals and currents being transmitted are also continuously increasing, thus making the electromagnetic interference between them more and more serious. Summary of the Invention

[0004] The main purpose of the present invention is to reduce the electromagnetic interference between terminals through the space surrounded by the first shielding housing and the second shielding housing.

[0005] To achieve the above object, the main structure of the present invention includes: a first connector, which includes a male terminal insulating colloid, a first shielding housing provided on the male terminal insulating colloid, and a second shielding housing provided on the male terminal insulating colloid. The first shielding housing and the second shielding housing are respectively located on both sides of the long side direction of the male terminal insulating colloid to form a first space surrounded by the first shielding housing; a second space formed by surrounding of the second shielding housing; a third space defined between the first shielding housing and the second shielding housing; a first male terminal provided on the male terminal insulating colloid and located in the first space; a second male terminal provided on the male terminal insulating colloid and located in the second space; and a plurality of third male terminals provided on the male terminal insulating colloid and located in the third space.

[0006] The first shielding housing has a plurality of first welding portions.

[0007] The second shielding housing has a plurality of second welding portions.

[0008] Wherein, at least one first docking portion is provided on the first shielding housing, and at least one second docking portion is provided on the second shielding housing.

[0009] Wherein, a plurality of colloid docking portions for docking the first docking portion and the second docking portion are provided on the male-end insulating colloid.

[0010] Wherein, the first connector is for connecting a second connector.

[0011] Wherein, the second connector includes a female-end insulating colloid and a shielding housing assembly provided on the female-end insulating colloid.

[0012] Wherein, the shielding housing assembly has an outer shielding housing and a plurality of inner shielding housings provided on the inner side of the outer shielding housing, and the inner shielding housings are perpendicular to the long side direction of the female-end insulating colloid, and a fourth space, a fifth space, and a sixth space are formed along the long side direction of the female-end insulating colloid in sequence by the shielding housing assembly.

[0013] Wherein, a first female terminal is provided in the fourth space, a plurality of second female terminals are provided in the fifth space, and a third female terminal is provided in the sixth space.

[0014] Wherein, at least one notch is provided on the outer shielding housing.

[0015] With the above structure, since the first shielding housing and the second shielding housing enclose a first space, a second space, and a third space, when the first connector and the second connector are docked, the first male terminal, the second male terminal, and the third male terminal can be respectively isolated in the first space, the second space, and the third space, and are mutually shielded by the first shielding housing and the second shielding housing to reduce the electromagnetic interference between the first male terminal, the second male terminal, and the third male terminal.

[0016] With the above technology, the problem of electromagnetic interference generated by conventional sockets and terminals can be broken through, achieving the practical progress of the above advantages. Brief Description of the Drawings

[0071] Please refer to it together with Figures 1 to 7Shown is a three-dimensional schematic diagram to a combined schematic diagram (III) of a preferred embodiment of the present invention.
