[0002] Any electrical discontinuity on a signal transmission line will affect signal quality. Some connectors on signal transmission lines use grounding terminals to provide shielding to maintain stability or efficiency during data transmission. However, as signal transmission rates increase, simply using grounding terminals on both sides of the signal terminals to provide shielding is no longer sufficient, thus requiring improvements to the aforementioned shielding effect. Utility Model Content

Prefixes for component names, such as first, second, etc., are only for distinguishing components and facilitating description, and do not impose any other limitations on the components; furthermore, components with the same prefix in different embodiments do not necessarily correspond. The correspondence of components in each embodiment should still be determined according to the specific structure described in each embodiment.

[0040] Please see Figures 1 to 4 An electrical connector 1 according to one embodiment includes an insulating body 12, a plurality of conductive terminals 14, two rear grounding members 16, four front grounding members 18, and two retaining tabs 20. The insulating body 12 is composed of a body 122 and a bottom engaging portion 124 and has a front side 12a and a rear side 12b. The insulating body 12 forms a mating groove 12c, which is exposed on the front side 12a. The plurality of conductive terminals 14 are fixedly arranged on the insulating body 12 along an arrangement direction Da (indicated by an arrow in the figure), forming two rows on both sides of the mating groove 12c (one conductive terminal 14 is selected from each row). The two rear grounding members 16 are fixed to the insulating body 12 corresponding to the two rows of conductive terminals 14 and are exposed on the rear side 12b of the insulating body 12, and are in contact with a portion of the conductive terminals 14. The four front grounding members 18 are also fixedly arranged on the insulating body 12 along the arrangement direction Da, forming two columns, which are respectively aligned with the original two rows of conductive terminals 14. The four front grounding elements 18 are exposed on the front side 12a of the insulating body 12 and can contact some of the conductive terminals 14. The two fixing pieces 20 are fixed to both sides of the insulating body 12 in the arrangement direction Da.

[0041] Each conductive terminal 14 includes a contact portion 142, a fixing portion 144, and a soldering portion 146. The contact portion 142 and the soldering portion 146 extend from the fixing portion 144 and are exposed in the insulating body 12 (the former is exposed in the insertion slot 12c; the latter is exposed on the rear side 12b of the insulating body 12). The conductive terminal 14 is fixed to the insulating body 12 by the fixing portion 144. The contact portion 142 is elastic relative to the insulating body 12 so as to elastically contact the conductive terminal of the external connector. The electrical connector 1 can be electrically fixed to an external carrier, such as soldered to a circuit board, by the soldering portion 146. The rear grounding member 16 includes a rear plate 162 and a plurality of rear contact terminals 164 (selected from the figures) extending from the rear plate 162. The rear plate 162 extends parallel to the arrangement direction Da, and the plurality of rear contact terminals 164 are exposed on the rear side 12b of the insulating body 12. The rear grounding member 16 is fixed to the insulating body 12 by a rear plate 162 (e.g., the rear plate 162 is embedded in the insulating body 12 and exposed on the rear side 12b of the insulating body 12), and contacts the conductive terminal 14 through the plurality of rear contact terminals 164. The front grounding member 18 includes a front plate 182 and a plurality of front contact terminals 184 (selected from the figures) extending from the front plate 182. The front plate 182 extends parallel to the arrangement direction Da, and the plurality of front contact terminals 184 are exposed in the insertion slot 12c and opposite the contact portion 142 of the conductive terminal 14. The front grounding member 18 is fixed to the insulating body 12 by the front plate 182 (e.g., the front plate 182 is embedded in the insulating body 12 and exposed on the front side 12a of the insulating body 12). The front grounding member 18 can contact the conductive terminal 14 through the front contact terminals 184.

[0042] Please also refer to Figure 5 Furthermore, taking a portion of the conductive terminals 14 in one row of conductive terminals 14 as an example, these conductive terminals 14 include a first terminal 14a, at least one second terminal 14b (e.g., two terminals), and a third terminal 14c arranged consecutively (in other words, the two second terminals 14b are located between the first terminal 14a and the third terminal 14c). For example, the first terminal 14a and the third terminal 14c serve as grounding terminals, and the second terminal 14b serves as a signal terminal. The rear plate 162 is opposite to the fixing portion 144 of the first terminal 14a, the second terminal 14b, and the third terminal 14c, and the rear contact terminals 164 corresponding to the first terminal 14a and the third terminal 14c respectively contact the solder portion 146 of the first terminal 14a and the solder portion 146 of the third terminal 14c. The rear grounding member 16 is insulated from the second terminal 14b. The front contact terminals 184 corresponding to the first terminal 14a and the third terminal 14c are respectively provided relative to the contact portions 142 of the first terminal 14a and the third terminal 14c (and are located between the contact portions 142 and the side wall of the insertion groove 12c). The front grounding member 18 is insulated from the second terminal 14b.

[0043] Furthermore, the electrical connector 1 allows a mating connector (not shown) to be inserted through the insertion slot 12c and is electrically connected to the mating connector through the plurality of conductive terminals 14, thus the electrical connector 1 has a mated state (such as...). Figure 6 (as shown) and an unplugged state (such as) Figure 5 (As shown). When the electrical connector 1 is in the unplugged state, the front contact terminal 184 does not contact the contact portions 142 of the first terminal 14a and the third terminal 14c. This configuration allows the contact portion 142 of each conductive terminal 14 to contact the conductive terminal of the mating connector with the same contact force when the mating connector is first inserted into the insertion slot 12c, making the mating connector subject to even force and easy to maintain smooth insertion. However, this is not a limitation in practice; for example, the front contact terminal 184 may slide to contact the contact portions 142 of the first terminal 14a and the third terminal 14c.

[0044] When the electrical connector 1 is in the plugged-in state, the front contact terminal 184 contacts the contact portions 142 of the first terminal 14a and the third terminal 14c respectively. Conversely, when the mating connector is inserted into the plug slot 12c, it pushes against the contact portions 142 of the first terminal 14a and the third terminal 14c, causing the contact portions 142 to move towards and contact the front contact terminal 184. At this time, the rear grounding member 16 and the front grounding member 18 simultaneously connect the first terminal 14a and the third terminal 14c (at both ends), ensuring a more complete shielding effect across the entire space between the first terminal 14a and the third terminal 14c (compared to the case where only a single end is connected).

[0045] In this embodiment, the soldering portion 146 of the conductive terminal 14 has a bottom surface 1462 and a top surface 1464 opposite to the bottom surface 1462. The rear contact terminals 164 corresponding to the first terminal 14a and the third terminal 14c respectively contact the top surface 1464 of the soldering portion 146 of the first terminal 14a and the third terminal 14c. The electrical connector 1 is soldered to a circuit board, for example, through the bottom surface 1462 of the soldering portion 146. In practice, by controlling the amount of solder paste, the rear contact terminals 164 can be soldered to the top surface 1464 of the soldering portion 146 at the same time as the soldering portion 146 is soldered to the circuit board.

[0046] Regarding the connection relationships between other conductive terminals 14 and the rear grounding member 16 and the front grounding member 18, please refer directly to the aforementioned connection relationships between the rear grounding member 16 and the front grounding member 18 and the first terminal 14a, the second terminal 14b, and a third terminal 14c, which will not be repeated here. Furthermore, in this embodiment, for the same row of conductive terminals 14, a single rear grounding member 16 is used to conduct the corresponding conductive terminal 14, and two front grounding members 18 are used to conduct the corresponding conductive terminal 14. However, this is not a limitation in practice; for example, the rear grounding member 16 can be structurally divided into two rear grounding members, and the two front grounding members 18 can also be structurally integrated into a single front grounding member.

[0047] In addition, in this embodiment, the electrical connector 1 has grounding elements (i.e., rear grounding element 16 and front grounding element 18) on both its front side 12a and rear side 12b. However, in practice, one of them can be implemented at a time, and it can still provide an improved shielding effect for the at least one second terminal 14b located between the first terminal 14a and the third terminal 14c.

[0048] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
