Description

Technical Field

[0001] The present invention provides a shielding structure for an electrical connector, especially 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. At this time, an electromagnetic field will be generated along with the current or voltage, resulting in interference caused by the electromagnetic field, thereby reducing the performance of the electronic device or generating incorrect signals. This is the so-called electromagnetic interference (EMI). Even when some devices are larger or the current passing through is larger, the generated electromagnetic interference will be more serious, thus affecting human health.

[0003] With the progress of the times, many electronic devices are becoming more and more miniaturized. However, while miniaturizing, there is also a requirement 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, thereby 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 shielding housing assembly.

[0005] To achieve the above object, the main structure of the present invention includes: a first connector, which includes a female terminal insulating colloid and a shielding housing assembly provided on the female terminal insulating colloid. The shielding housing assembly includes an outer shielding housing and a plurality of inner shielding housings provided inside the outer shielding housing. The inner shielding housings are perpendicular to the long side direction of the female terminal insulating colloid, and a first space, a second space, and a third space are sequentially formed by the shielding housing assembly along the long side direction of the female terminal insulating colloid; a first female terminal, which is provided on the female terminal insulating colloid and is located in the first space; a plurality of second female terminals, which are provided on the female terminal insulating colloid and are located in the second space; and a third female terminal, which is provided on the female terminal insulating colloid and is located in the third space.

[0006] At least one notch is provided on the outer shielding housing.

[0007] A plurality of shielding docking parts are provided on the outer shielding housing.

[0008] A plurality of colloid docking parts for docking the shielding docking parts are provided on the female terminal insulating colloid.

[0009] The first connector is for connecting a second connector.

[0010] Wherein the second connector includes a male-end insulating colloid, a first shielding housing disposed on the male-end insulating colloid, and a second shielding housing disposed on the male-end insulating colloid.

[0011] Wherein the first shielding housing surrounds to form a fourth space, a fifth space is defined between the first shielding housing and the second shielding housing, and the second shielding housing surrounds to form a sixth space.

[0012] Wherein a first male terminal is disposed in the fourth space, a plurality of second male terminals are disposed in the fifth space, and a third male terminal is disposed in the sixth space.

[0013] Wherein the first shielding housing has a plurality of first welding portions.

[0014] Wherein the second shielding housing has a plurality of second welding portions.

[0015] With the above structure, the shielding housing assembly will sequentially surround the first space, the second space, and the third space along the long side direction of the female-end insulating colloid. Thereby, when the first connector is docked with the second connector, the first female terminal, the second female terminal, and the third female terminal can be respectively isolated in the first space, the second space, and the third space, and are mutually shielded by the outer shielding housing and the inner shielding housing to reduce the electromagnetic interference between the first female terminal, the second female terminal, and the third female terminal.

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

[0052] A first connector 100, the first connector 100 includes a female end insulating colloid 1, a shielding housing assembly 2 provided on the female end insulating colloid 1. The shielding housing assembly 2 includes an outer shielding housing 21 and a plurality of inner shielding housings 22 provided inside the outer shielding housing 21. And in cooperation with those shown in the first figure and the second figure, the inner shielding housings 22 are perpendicular to the long side direction of the female end insulating colloid 1, so that the shielding housing assembly 2 can sequentially form a first space 11, a second space 12, and a third space 13 along the long side direction of the female end insulating colloid 1;

[0053] A first female terminal 31 provided on the female end insulating colloid 1, and the first female terminal 31 is located in the first space 11;

[0056] At least one notch 211 provided on the outer shielding housing 21;

[0057] A plurality of shielding docking parts 212 provided on the outer shielding housing 21;

[0058] A plurality of colloid docking parts 14 provided on the female end insulating colloid 1 for docking with the shielding docking parts 212;

[0059] A second connector 400 connected to the first connector 100. The second connector 400 includes a male end insulating colloid 4, a first shielding housing 51 provided on the male end insulating colloid 4, and a second shielding housing 52 provided on the male end insulating colloid 4. The first shielding housing 51 forms a fourth space 41 around the male end insulating colloid 4. A fifth space 42 is defined between the first shielding housing 51 and the second shielding housing 52. The second shielding housing 52 forms a sixth space 43 around the male end insulating colloid 4;

[0060] A first male terminal 61 disposed on the common terminal insulating colloid 4 and located within the fourth space 41;

[0061] A plurality of second male terminals 62 disposed on the common terminal insulating colloid 4 and located within the fifth space 42;

[0062] A third male terminal 63 disposed on the common terminal insulating colloid 4 and located within the sixth space 43;

[0063] A plurality of first welding portions 511 disposed on the first shielding housing 51; and

[0064] A plurality of second welding portions 521 disposed on the second shielding housing 52.

[0065] Through the above description, the structure of the present technology can already be understood. Based on the corresponding cooperation of this structure, the advantage of reducing electromagnetic interference between terminals can be achieved, and a detailed explanation will be provided in the following description.

[0066] Please also refer to Figures 1 to 7 As shown, it is a perspective view of the female end to the combined view (III) of the preferred embodiment of the present invention. When the above components are assembled, it can be clearly seen from the figure that the user can dispose the first female terminal 31, the second female terminal 32, and the third female terminal 33 on the female terminal insulating colloid 1, then connect the outer shielding housing 21 to the colloid docking portion 14 via the shielding docking portion 212, and at the same time dispose the inner shielding housing 22 on the female terminal insulating colloid 1. Thus, the first space 11, the second space 12, and the third space 13 are surrounded by the shielding housing assembly 2. The first female terminal 31 is located within the first space 11, the second female terminal 32 is located within the second space 12, and the third female terminal 33 is located within the third space 13. Thus, the electromagnetic interference between the first female terminal 31, the second female terminal 32, and the third female terminal 33 is shielded by the outer shielding housing 21 and the inner shielding housing 22.

[0067] And dispose the first male terminal 61, the second male terminal 62, and the third male terminal 63 on the common terminal insulating colloid 4, and make the first male terminal 61 located within the fourth space 41 surrounded by the first shielding housing 51 and the second shielding housing 52, the second male terminal 62 located within the fifth space 42, and the third male terminal 63 located within the sixth space 43. Thus, the electromagnetic interference between the first male terminal 61, the second male terminal 62, and the third male terminal 63 is shielded by the first shielding housing 51 and the second shielding housing 52.

[0068] In use, the first connector 100 and the second connector 400 can be respectively installed on the corresponding circuit boards, and the first connector 100 and the second connector 400 are connected to each other. When connecting, the position of the first space 11 corresponds to the position of the fourth space 41; the position of the second space 12 corresponds to the position of the fifth space 42; the position of the third space 13 corresponds to the position of the sixth space 43, and the first male terminal 61 is connected to the first female terminal 31; the second male terminal 62 is connected to the second female terminal 32; the third male terminal 63 is connected to the third female terminal 33, and then the signal and power transmission actions can be carried out.

[0069] While transmitting the signal, the shielding effect between the first male terminal 61, the second male terminal 62, and the third male terminal 63 can be enhanced by the cooperation of the first shielding shell 51, the second shielding shell 52, the first welding portion 511, and the second welding portion 521. At the same time, the cooperation of the outer shielding shell 21, the inner shielding shell 22, and the notch 211 enhances the shielding effect between the first female terminal 31, the second female terminal 32, and the third female terminal 33. Through the above structure, the overall shielding effect can be enhanced to reduce the electromagnetic interference (EMI) between the terminals.
