Socket electrical connector

Abstract

A socket electrical connector includes a metal shell and at least one plug-in module. The metal shell includes two first walls, two second walls and a plurality of protrusions. The first wall and the second wall surround a plug-in space. The protrusion extends from the first wall to the plug-in space, and the first wall and the protrusion are continuously formed and closed. The plug-in module is surrounded by the metal shell. The plug-in module includes an insulating body, a first terminal, a second terminal and a grounding plate, and the grounding plate is located between the first terminal and the second terminal. When the socket electrical connector is connected to the plug electrical connector, the protrusion contacts the shielding shell of the plug electrical connector. Since the structure of the metal shell does not have an opening, it can be tightly fitted to achieve a waterproof effect after the plug-in module and the plug electrical connector are assembled, and the contact of the protrusion can suppress electromagnetic interference and radio frequency interference.

Description

Technical Field

[0001] The invention relates to an electrical connector, and in particular to a USB socket electrical connector. Background Art

[0002] With the formulation of the Universal Serial Bus (USB) interface specification, more and more products are using this specification. Currently, the USB2.0 transmission specification is the majority in the market, but since the USB interface has been widely used in high-frequency, radio frequency, wireless or Bluetooth transmitters and other products, the USB2.0 transmission rate is increasingly unable to meet the needs of existing products.

[0003] Therefore, the transmission specifications of USB3.0 and USB3.1 are gradually developing and expanding their market share. However, as the amount of digital data converges, faster digital data transmission speeds are required, and external electromagnetic interference or signal crosstalk between internal terminals will affect the product effect.

[0004] In order to suppress signal crosstalk, external electromagnetic interference or radio frequency interference, shielding components are added to the overall structural design, resulting in more overall parts and increased difficulty in the overall process and assembly. In order to cooperate with the fixture, multiple openings need to be opened in the structure, which reduces the strength and thus reduces the yield rate in manufacturing. In addition, many recent products are also designed for use in water. However, if such a structure with openings accidentally causes the product to come into contact with water, water droplets may flow directly into the interior, affecting or even damaging the components. When the plug electrical connector is damaged, the motherboard needs to be manually removed and replaced, and the plug electrical connector needs to be replaced, and the overall maintenance cost is expensive.

[0005] Therefore, what the industry needs at present is a plug electrical connector that can provide waterproof effect and improve strength and shielding effect. Summary of the invention

[0006] The main purpose of the present invention is to provide a socket electrical connector. The socket electrical connector includes a metal shell and at least one plug-in module. The metal shell includes two first walls, two second walls and a plurality of protrusions. The two first walls are opposite to each other, the two second walls are opposite to each other, and each second wall is connected to the two first walls, and the two first walls and the two second walls surround a plug-in space. The protrusion extends from the first wall to the plug-in space, and the first wall and the protrusion are continuous and closed. At least one plug-in module is surrounded by the metal shell. Each plug-in module includes an insulating body, a plurality of first terminals, a plurality of second terminals and a grounding plate, wherein the first terminal, the second terminal and the grounding plate are fixed in the insulating body, and the grounding plate is located between the first terminal and the second terminal. When the socket electrical connector is connected to a plug electrical connector, the protrusion contacts a shielding shell of the plug electrical connector.

[0007] In one embodiment, the metal shell includes a plurality of grooves, and the grooves are located on the first wall, opposite to the other surface of the protrusion.

[0008] In one embodiment, the metal shell is integrally formed.

[0009] In one embodiment, the insulating body includes a seat and a tongue plate, the tongue plate extends from one side of the seat, each first terminal includes a first contact portion, each second terminal includes a second contact portion, and the first contact portion and the second contact portion are respectively located on an upper surface and a lower surface of the tongue plate. Further, the grounding plate is exposed on the side surface of the tongue plate. Further, the first terminal also includes a first welding portion, and the second terminal also includes a second welding portion. The first welding portion extends from the first contact portion, and the second welding portion extends from the second contact portion, and the first welding portion and the second welding portion protrude from the seat.

[0010] In one embodiment, the first terminal, the second terminal and the grounding plate are fixed in the insulating body by inserting molding. In another embodiment, the first terminal, the second terminal and the grounding plate are fixed in the insulating body by assembly.

[0011] In one embodiment, the plug module further comprises a first conductive sheet and a second conductive sheet. The first conductive sheet is located on the upper surface of the insulating body to partially shield the first terminal, and the second conductive sheet is located on the lower surface of the insulating body to partially shield the second terminal.

[0012] In one embodiment, the electrical socket connector further includes a second metal shell, and the second metal is assembled with the metal shell and is disposed outside the metal shell.

[0013] In one embodiment, the pin positions of the first terminal and the second terminal are arranged in reverse order. Therefore, no matter the plug electrical connector is inserted into the socket electrical connector in a forward direction or a reverse direction, the signal can be correctly transmitted.

[0014] In the above disclosed embodiments, since the outer wall of the metal shell has no opening, it can be tightly fitted with the plug module and the plug electrical connector after being assembled and plugged in, so as to achieve a waterproof effect. The protrusion on the metal shell can contact the shielding shell of the plug electrical connector, making the combination tighter, improving the tightness and waterproof effect, and can contact each other to form a ground loop, further suppressing electromagnetic interference (EMI) and radio frequency interference (RFI).

Figure 1-Figure 4 As shown, the socket electrical connector 1 includes a metal housing 10 and a plug module 20. The plug module is surrounded by the metal housing 10. In this embodiment, one plug module 20 is presented, but it is not limited thereto. In fact, the metal housing 10 may surround multiple plug modules 20.

[0049] The metal shell 10 includes two first walls 11 and two second walls 13, wherein the first wall 11 may be an upper wall and a lower wall, and the second wall 13 is a left wall and a right wall. The two first walls 11 are opposite to each other, the two second walls 13 are opposite to each other, and each second wall 13 connects the two first walls 11. The first wall 11 and the second wall 13 enclose a plug-in space 15. One end of the plug-in space 15 corresponds to the plug-in frame opening of the plug. The metal shell 10 further includes a plurality of protrusions 17, which extend from the first wall 11 toward the plug-in space 15, and the first wall 11 and the protrusions 17 are continuously formed and closed, that is, the first wall 11 has no opening, and the second wall 13 has no opening.

[0050] In addition, the metal shell 10 includes a plurality of grooves 19. The grooves 19 are located on the first wall 11, opposite to the other surface 111 of the protrusion. The protrusion 17 and the grooves 19 can be two corresponding surfaces of an integral body. The protrusion 17 and the grooves 19 can be formed independently. In addition, the metal shell 10 is integrally formed, and can also be formed by welding multiple plates.

[0051] The plug module 20 includes an insulating body 30, a plurality of first terminals 40, a plurality of second terminals 50 and a grounding plate 60. The first terminal 40, the second terminal 50 and the grounding plate 60 are fixed in the insulating body 30. The first terminal 40, the second terminal 50 and the grounding plate 60 can be assembled to the insulating body 30 by assembly, or the first terminal 40, the second terminal 50 and the grounding plate 60 can be molded and fixed by insert-molding to make the whole more stable. The grounding plate 60 is located between the first terminal 40 and the second terminal 50 to provide a metal shielding effect to suppress signal crosstalk between the terminals.

[0052] The insulating body 30 includes a seat 31 and a tongue 33. The tongue 33 extends from one side of the seat 31. The first terminal 40 includes a first contact portion 41 and a first welding portion 43, and the second terminal 50 includes a second contact portion 51 and a second welding portion 53. The first contact portion 41 and the second contact portion 43 are respectively located on an upper surface 331 and a lower surface 333 of the tongue 33. The first welding portion 43 extends from the first contact portion 41, and the second welding portion 53 extends from the second contact portion 51, and the first welding portion 43 and the second welding portion 53 protrude from the seat 31. In addition, the grounding plate 60 protrudes from the side surface 335 of the tongue 33.

[0053] Furthermore, the plug module 20 further includes a first conductive sheet 71 and a second conductive sheet 73. The first conductive sheet 71 is located on the upper portion of the insulating body 30 to partially shield the first terminal 40, and the second conductive sheet 73 is located on the lower portion of the insulating body 40 to partially shield the second terminal 50.

[0054] Furthermore, the electrical socket connector 1 further includes a second metal shell 80 . The second metal shell 80 is assembled with the metal shell 10 and is disposed outside the metal shell 10 to achieve a further shielding effect.

[0055] See also Figure 5-Figure 6 , are cross-sectional schematic diagrams of the socket electrical connector and the plug electrical connector of the present invention before and after assembly. Figure 5-Figure 6As shown, when the socket electrical connector 1 is connected to a plug electrical connector 500, the protrusion 17 contacts a shielding shell 510 of the plug electrical connector 500. Therefore, the protrusion 17 and the shielding shell 510 can form a grounding loop together, greatly suppressing electromagnetic interference and radio frequency interference. In addition, the protrusion 17 can also make the plug-in connection between the socket electrical connector 1 and the plug electrical connector 500 more tightly fitted, and can further enhance the tight and waterproof effect.

[0056] Furthermore, the pin positions of the first terminal 40 and the second terminal 50 are arranged in reverse order, so that the signal can be correctly transmitted regardless of whether the plug electrical connector 500 is inserted in the forward direction or the reverse direction. The protrusion 17 can also serve as a guide for inserting the plug electrical connector 500, so that the plug electrical connector 500 is inserted in the correct position.

[0057] Therefore, the socket electrical connector provided in the above embodiment has no opening on the outer wall of the metal shell, so it can be tightly fitted after being assembled with the plug module and plugged with the plug electrical connector, achieving a waterproof effect and avoiding damage to the components caused by water vapor leakage. In addition, the protrusion on the metal shell can contact the shielding shell of the plug electrical connector, making the combination tighter, improving the tightness and waterproof effect, and can contact each other to form a grounding loop, further suppressing electromagnetic interference and radio frequency interference, and better meeting high-frequency and high-transmission rate applications.
