[0044] The detailed description and technical contents of this application are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit this application.

[0045] The present application provides a grounding-enhanced electrical connector that can be applied to any electrical connector that requires shielding and grounding, and is particularly suitable for DP connectors (DP is the abbreviation for DisplayPort (digital video interface standard)). Figures 1 to 4 The first embodiment of the present application is shown as follows. Figure 5 The second embodiment is shown.

[0046] like Figures 1 to 4 As shown, a first embodiment of the ground-enhanced electrical connector (hereinafter referred to as electrical connector) of the present application includes an insulating body 1 , a terminal assembly 2 and a metal shell 4 .

[0047] The terminal assembly 2 is disposed on the insulating body 1 and includes, for example, a first terminal row 21 and a second terminal row 22, which may be spaced apart and opposed to each other. The first terminal row 21 includes a plurality of first terminals (not labeled) arranged side by side, including at least one first grounding terminal 211; the second terminal row 22 includes a plurality of second terminals (not labeled) arranged side by side, including at least one second grounding terminal 221. This application does not limit the number of first and second grounding terminals 211, 221; in this embodiment, at least two are used as an example. Each first grounding terminal 211 extends (or is connected to) a first conductive pin 2111, and each second grounding terminal 221 extends (or is connected to) a second conductive pin 2211. The extended end portion of each first conductive pin 2111 and the extended end portion of each second conductive pin 2211 are exposed from two side surfaces (not labeled) of the insulating body 1, forming two protrusions E.

[0048] The metal shell 4 has two inner wall surfaces 41, which are preferably opposite to each other. Figure 3 、 Figure 4 As shown, the metal shell 4 surrounds the insulating body 1 on which the terminal assembly 2 is provided, and the protrusion E of each first conductive pin 2111 and the protrusion E of each second conductive pin 2211 respectively abut against the two inner wall surfaces 41 to be conductively connected to each other.

[0049] By this, Figure 3 and Figure 4 As shown, since each first conductive pin 2111 of the first terminal row 21 abuts against one of the two inner wall surfaces 41 of the metal shell 4 with its protrusion E, each second conductive pin 2211 of the second terminal row 22 abuts against the other of the two inner wall surfaces 41 of the metal shell 4 with its protrusion E, so as to conduct the load through the metal shell 4, the metal shell 4 is used to strengthen the grounding effect.

[0050] It should be noted that if Figure 4As shown, each first conductive pin 2111 extends toward one of the two inner wall surfaces 41 through an initial bend and then bends again at the distal end of the extension to form a protrusion E that is exposed from the insulating body 1 as shown. Each second conductive pin 2211 also extends toward the other of the two inner wall surfaces 41 through an initial bend and then bends again at the distal end of the extension to form a protrusion E that is exposed from the insulating body 1 as shown. In other words, the initial bends of each first conductive pin 2111 and each second conductive pin 2211 are in opposite directions from each first ground terminal 211 and each second ground terminal 221, respectively.

[0051] like Figure 2 and Figure 4 As shown, each first terminal of the first terminal row 21 forms a welding portion (not marked with an element symbol) on the rear end face of the insulating body 1, and each second terminal of the second terminal row 22 also forms a welding portion (not marked with an element symbol) on the rear end face of the insulating body 1. The metal shell 4 also extends at least one plug-in portion 42 at the rear end face corresponding to the insulating body 1. The electrical connector of the present application can utilize these welding portions and plug-in portions 42 for conducting. It should be noted that the method for soldering all the first terminals of the first terminal row 21 and all the second terminals of the second terminal row 22 to a circuit board (not shown) is not limited in the present application. In other words, the welding portions of all the first terminals and all the second terminals can be as follows Figure 2 The flat pins shown are bent (applied in surface mount technology (SMT)), or they may be straight pins without bending (not shown).

[0052] In addition, if Figures 1 to 4 As shown, the insulating body 1 further has a tongue plate 135 extending forward, the front end of each first terminal of the first terminal row 21 (including the first grounding terminal 211) is flatly attached to one side of the tongue plate 135, and the front end of each second terminal of the second terminal row 22 (including the second grounding terminal 221) is flatly attached to the other side of the tongue plate 135. Figure 4 As shown, taking each first terminal of the first terminal row 21 as an example, its front section (as mentioned above), rear section and protrusion E are arranged from low to high in sequence; as for each second terminal of the second terminal row 22, it is symmetrically designed with the first terminal.

[0053] The insulating body 1 can be a single-piece structure (not shown) or a multi-piece structure as shown in the figure. Figure 1 、 Figure 2 and Figure 4 As shown, the multi-piece insulating body 1 includes a first block 11, a second block 12 and a base 13, which will be described below.

[0054] The base 13 is provided with a first combination portion 131 and a second combination portion 132. The base 13 has the aforementioned tongue plate 135. Specifically, the first combination portion 131 and the second combination portion 132 are both provided as recessed grooves, but the present application is not limited to this. The first terminal row 21 is provided on the first block 11, and the second terminal row 22 is provided on the second block 12.

[0055] The first block 11 provided with the first terminal block 21 is correspondingly embedded in the first assembly portion 131 of the base 13 , and the second block 12 provided with the second terminal block 22 is correspondingly embedded in the second assembly portion 132 of the base 13 .

[0056] like Figure 5 As shown, it is the second embodiment of the electrical connector of the present application. The second embodiment is roughly the same as the aforementioned first embodiment, with the difference that it further includes a shielding member 3. The shielding member 3 is a metal shielding sheet and is arranged on the insulating body 1, and the shielding member 3 is separated between the first terminal row 21 and the second terminal row 22, so that the shielding member 3 is used to shield between the first terminal row 21 and the second terminal row 22, thereby having the effect of avoiding signal interference. Specifically, the shielding member 3 is arranged on the base 13. In addition, the shielding member 3 can also extend at least one plug-in portion 36 corresponding to the rear end face of the insulating body 1, so as to utilize the plug-in portion 36 for conducting connection.

[0057] In other embodiments not shown in the figures, the first conductive pin 2111 and the second conductive pin 2211 may not be configured to extend from the first ground terminal 211 and the second ground terminal 221, respectively, as described above. Instead, they may be connected as additional connections. That is, the first conductive pin 2111 and the second conductive pin 2211 may be connected between the first ground terminal 211 and one of the two inner walls 41, and between the second ground terminal 221 and the other of the two inner walls 41, respectively. This approach can also achieve the same effect. Of course, the first conductive pin 2111 and the second conductive pin 2211 may also be configured to extend from the metal housing 4 (e.g., from its two inner walls 41), and this is not a limitation of the present application.

[0058] In summary, the ground-enhanced electrical connector of the present application can achieve the intended purpose and effect and solve the shortcomings of the prior art, and therefore a patent application is filed.

[0059] The above description is merely a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural changes made by using the description and drawings of the present application are also included in the scope of the rights of the present application and are hereby stated.
