Abstract

The present invention is a plug electrical connector including a plurality of terminals and an insulating body, a pair of grounding fasteners, a shielding spring and a shielding shell. Each terminal has a contact section and an elastic section. Each contact section has a stop surface. The insulating body partially covers these terminals and has a plurality of stop edges. When the plug electrical connector and the socket electrical connector are plugged into each other, the shape of each elastic section changes so that the corresponding contact section is offset until the corresponding stop edge abuts against the corresponding stop surface, and each contact section does not protrude from the insulating body. When the plug electrical connector is not plugged into the socket electrical connector, the shape of each elastic section is restored so that the corresponding contact section is reset and the corresponding stop edge is away from the stop surface.

Description

Technical Field

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

[0002] Electrical connectors are common components on electronic devices. They can be connected to matching electrical connectors on other electronic devices to serve as a medium for transmitting signals and power between two electronic devices. Common electrical connectors include Universal Serial Bus (USB) electrical connectors. The USB protocol has added the Type C electrical connector specification, which not only provides an ultra-high data transmission rate of 10Gbps, but also has a symmetrical plug-in that can be plugged in either direction. Therefore, it is widely used in various electronic devices, such as notebook computers.

[0003] In the case of the USB Type C plug electrical connector, in order to prevent the contact end of the terminal located in the insulating body from passing through the opening of the insulating body and contacting the shielding shell after being deflected, an insulating film is usually adhered to the insulating body to cover the opening of the insulating body. Because of the isolation of the insulating film, the terminal will not directly contact the shielding shell after being pressed and deflected by the tongue of the corresponding socket electrical connector. However, the above-mentioned insulating film has the following disadvantages. It takes more work hours to stick the insulating film. The stickiness of the insulating film will slip and fall off easily after long-term use. The insulating film is easily broken by the friction of the contact end of the terminal, resulting in insulation failure. Summary of the invention

[0004] The invention provides a plug electrical connector which can prevent the contact end of a terminal located in an insulating body from passing through an opening of the insulating body and contacting a shielding shell after being deflected without using an insulating film.

[0005] A plug electrical connector of the present invention is suitable for mutual plugging with a socket electrical connector. The plug electrical connector includes a plurality of terminals, an insulating body, a pair of grounding fasteners, a shielding spring and a shielding shell. Each terminal has a contact section and an elastic section. Each contact section has a stop surface. The insulating body partially covers these terminals and has a plurality of stop edges. When the plug electrical connector and the socket electrical connector are mutually plugged, the shape of each elastic section changes so that the corresponding contact section is offset until the corresponding stop edge abuts against the corresponding stop surface, and each contact section does not protrude from the insulating body. When the plug electrical connector is not mutually plugged with the socket electrical connector, the shape of each elastic section is restored so that the corresponding contact section is reset and the corresponding stop edge is away from the corresponding stop surface. The pair of grounding fasteners are installed to the insulating body and are respectively located on both sides of these terminals to be mutually buckled with the socket electrical connector. The shielding spring is installed to the insulating body to contact the socket electrical connector. The shielding shell accommodates these terminals, the insulating body, the pair of grounding fasteners and the shielding spring.

[0006] In some embodiments, the insulating body has a plurality of openings, and one end of each opening close to the interior of the insulating body forms a corresponding stop edge.

[0007] In some embodiments, when the plug electrical connector and the socket electrical connector are plugged into each other, each contact segment moves into the space surrounded by the corresponding opening, and when the plug electrical connector and the socket electrical connector are not plugged into each other, each contact segment moves out of the space surrounded by the corresponding opening.

[0008] In some embodiments, the insulating body has a locking protrusion, the shielding spring has a locking slot, the locking protrusion matches the locking slot, and the ends of the openings away from the interior of the insulating body are located at the locking protrusion.

[0009] In some embodiments, the above-mentioned plug electrical connector further includes a grounding plate mounted to the insulating body and located between the first terminals and the second terminals.

[0010] In some embodiments, the grounding plate and the pair of grounding fasteners are integrally formed.

[0011] In some embodiments, the above-mentioned terminals include multiple first terminals and multiple second terminals, the insulating body includes a first rear insulating portion, a second rear insulating portion and a front insulating portion, the first rear insulating portion is combined with these first terminals, the second rear insulating portion is combined with these second terminals, and the first rear insulating portion and the second rear insulating portion are assembled to the front insulating portion so that these first terminals and these second terminals are accommodated in the front insulating portion.

[0012] In some embodiments, the above-mentioned terminals include multiple first terminals and multiple second terminals, the insulating body includes a first insulating part and a second insulating part, the first terminals are installed to the first insulating part, the second terminals are installed to the second insulating part, and the first insulating part and the second insulating part are assembled together.

[0013] In some embodiments, each of the above-mentioned terminals has a fixing section and a welding section, and the elastic section is located between the corresponding contact section and the corresponding fixing section.

[0014] Based on the above, in the present invention, the contact section of the terminal is offset until the stop edge of the insulating body abuts against the stop surface of the contact section, so that the contact section does not protrude from the insulating body to avoid contacting the shielding shell. Therefore, compared with the prior art, the present invention does not need to use an insulating film, so it can avoid the many problems derived from using an insulating film to isolate the contact section of the terminal from the shielding shell.

DETAILED DESCRIPTION

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 The plug electrical connector 100 of this embodiment is suitable for connecting with a socket electrical connector 200 (such as Figure 4 The plug electrical connector 100 is, for example, a USB TYPE-C specification standard. The plug electrical connector 100 includes a plurality of terminals and an insulating body partially covering the terminals. In the present embodiment, the terminals include a plurality of first terminals 110a and a plurality of second terminals 110b, and the insulating body includes a first rear insulating portion 120a, a second rear insulating portion 120b, and a front insulating portion 120c. The first rear insulating portion 120a is combined with the first terminals 110a, and the second rear insulating portion 120b is combined with the second terminals 110b. The first rear insulating portion 120a and the second rear insulating portion 120b are assembled to the front insulating portion 120c, so that the first terminals 110a and the second terminals 110b are accommodated in the front insulating portion 120c.

[0026] Please refer to Figure 2 and Figure 3 In this embodiment, the plug electrical connector 100 further includes a pair of grounding fasteners 130, a pair of shielding springs 140 and a shielding shell 150. The pair of grounding fasteners 130 are mounted to the insulating body (i.e., the front insulating portion 120c) and are respectively located on both sides of the terminals (i.e., the first terminals 110a and the second terminals 110b) to be mutually buckled with the socket electrical connector 200. The shielding spring 140 is mounted to the insulating body (i.e., the front insulating portion 120c) to contact the socket electrical connector 200. The shielding shell 150 accommodates the terminals (i.e., the first terminals 110a and the second terminals 110b), the insulating body (i.e., the first rear insulating portion 120a, the second rear insulating portion 120b and the front insulating portion 120c), the pair of grounding fasteners 130 and the pair of shielding springs 140.

[0027] Please refer to Figure 2 and Figure 3 In this embodiment, the insulating body (i.e., the front insulating portion 120c) has a snap-fitting protrusion 122, the shielding spring 140 has a snap-fitting slot 142, the snap-fitting protrusion 122 matches the snap-fitting slot 142, and the ends of the openings 121 away from the interior of the insulating body (i.e., the front insulating portion 120c) are located at the snap-fitting protrusion 122. In addition, the plug electrical connector 100 further includes a grounding plate 132, which is mounted to the insulating body (i.e., the front insulating portion 120c) and is located between the first terminals 110a and the second terminals 110b. In this embodiment, the grounding plate 132 is integrally formed with the pair of grounding fasteners 130, but the present invention is not limited thereto. In other embodiments, the pair of grounding fasteners 130 and the grounding plate 132 may also be multiple independent components.

[0028] Please refer to Figure 3 In this embodiment, each terminal (i.e., each first terminal 110a or each second terminal 110b) has a contact section 111, an elastic section 112, a fixed section 113, and a welding section 114. The contact section 111 is used to contact the pad (e.g., Figure 5 ). The elastic section 112 is located between the corresponding contact section 111 and the corresponding fixed section 113 to provide elastic stress to the contact section 111 relative to the fixed section 113. The fixed section 113 is fixed in the insulating body (i.e., the first rear insulating portion 120a or the second rear insulating portion 120b). The welding section 114 is used for welding to the circuit board.

[0029] Please refer to Figures 3 to 5 In addition, in order to prevent the contact segment 111 of each terminal (i.e., each first terminal 110a or each second terminal 110b) from contacting the shielding shell 150 after moving, each contact segment 111 has a stop surface 111a, and the insulating body (i.e., the front insulating portion 120c) has a plurality of stop edges 121a, which are used to respectively abut against these stop surfaces 111a to limit the position of these contact segments 111 relative to the insulating body (i.e., the front insulating portion 120c).

[0030] like Figure 3 As shown, when the plug electrical connector 100 is not plugged into the socket electrical connector 200, each contact segment 111 does not contact the insulating body (ie, the front insulating portion 120c). Figure 4 and Figure 5 As shown, when the plug electrical connector 100 and the socket electrical connector 200 are plugged into each other, the shape of each elastic segment 112 changes so that the corresponding contact segment 111 is offset until the corresponding stop edge 121a abuts against the corresponding stop surface 111a, and each contact segment 111 does not protrude from the insulating body (i.e., the front insulating portion 120c) to avoid contacting the shielding shell 150. Figure 3As shown, when the plug electrical connector 100 is not plugged into the socket electrical connector 200 , the shape of each elastic segment 112 is restored so that the corresponding contact segment 111 is reset and the corresponding stop edge 121a is away from the corresponding stop surface 111a .

[0031] Please refer to Figure 2 and Figure 3 In this embodiment, the insulating body (i.e., the front insulating portion 120c) has a plurality of openings 121 to prevent each terminal (i.e., each first terminal 110a or each second terminal 110b) from interfering with the insulating body (i.e., the front insulating portion 120c) in structure when moving. In this embodiment, one end of each opening 121 close to the inside of the insulating body (i.e., the front insulating portion 120c) forms a corresponding stop edge 121a.

[0032] like Figure 3 As shown, when the plug electrical connector 100 is not plugged into the socket electrical connector 200, each contact segment 111 is not located in the space S surrounded by the corresponding opening 121. Figure 5 As shown, when the plug electrical connector 100 and the socket electrical connector 200 are plugged into each other, each contact segment 111 moves into the space S surrounded by the corresponding opening 121. Figure 3 As shown, when the plug electrical connector 100 is not plugged into the socket electrical connector 200 , each contact segment 111 moves out of the space S surrounded by the corresponding opening 121 .

[0033] Please refer to Figure 3 In this embodiment, the insulating body is divided into three structurally independent parts, namely the first rear insulating part 120a, the second rear insulating part 120b and the front insulating part 120c. In other embodiments, the insulating body may also be composed of two independent parts or a single component.

[0034] Please refer to Figure 6 , different from Figure 3 The insulating body of the embodiment is composed of three independent parts. Figure 6 The insulating body of the plug connector 100 of the embodiment includes a first insulating portion 120m and a second insulating portion 120n, the first terminals 110a are mounted to the first insulating portion 120m, the second terminals 110b are mounted to the second insulating portion 120n, and the first insulating portion 120m and the second insulating portion 120n are assembled together.

[0035] Please refer to Figure 7 , different from Figure 3 and Figure 6 The insulating body of the embodiment is composed of three and two independent parts respectively. Figure 7The plug connector 100 of the embodiment adopts a single insulating body 120s, and the first terminals 110a and the second terminals 110b are mounted to the single insulating body 120s.

[0036] In summary, in the present invention, the contact section of the terminal is offset until the stop edge of the insulating body abuts against the stop surface of the contact section, so that the contact section does not protrude from the insulating body to avoid contacting the shielding shell. Therefore, compared with the prior art, the present invention does not need to use an insulating film, so it can avoid the many problems derived from using an insulating film to isolate the contact section of the terminal from the shielding shell.
