Description

Technical Field

[0001] This invention relates to an electrical connector, and more particularly to an electrical connector with good shielding effect. Background Technology

[0002] Chinese patent application number CN202121892308.3 discloses a female connector assembly, including a female connector shielding shell and a female connector signal terminal component. The female connector signal terminal component has a housing in the middle, with one end being an arched terminal and the other end protruding slightly from the housing and bent downwards. The female connector shielding shell has a full-enclosed structure, with one housing corresponding to one female connector shielding shell. The female connector shielding shell has an opening, with the arched terminal of the female connector signal terminal component exposed at the opening. The female connector shielding shell has protruding spring tabs on both sides, which contact each other to form an overall shield.

[0003] The above structure has the following problems:

[0004] The two female shield shells are in contact with each other by their two oppositely arranged side walls being pressed together, which is essentially equivalent to two planes being pressed together. Therefore, the contact between the two female shield shells cannot be guaranteed to be stable, and it is difficult to guarantee the overall shielding effect. Furthermore, the two female shield shells are pressed together by their two oppositely arranged side walls, which makes the distance between the two female shield shells relatively close. The distance between the female signal terminals they cover is reduced, and their crosstalk will also increase.

[0005] Therefore, it is necessary to design a new electrical connector to overcome the above problems. Summary of the Invention

[0006] In view of the problems faced by the prior art, the purpose of this invention is to provide an electrical connector with better shielding effect.

[0007] To achieve the above objectives, the present invention employs the following technical means:

[0008] An electrical connector, for interlocking with a mating element along a mating direction, is characterized by comprising: an insulating body; a plurality of conductive components arranged in at least one row along a first direction and housed within the insulating body, the first direction being perpendicular to the mating direction; each conductive component including a shielding shell and at least one signal terminal housed within the shielding shell; two grounding terminals provided between every two shielding shells in the first direction, one grounding terminal corresponding to one shielding shell; wherein the two grounding terminals are conductively connected to a grounding conductor of the mating element; each grounding terminal including a U-shaped connecting portion and a contact arm extending from the U-shaped connecting portion; each U-shaped connecting portion including a first wall, a second wall spaced apart from the first wall, and a bent portion connecting the first wall and the second wall; the contact arm extending from the second wall along the mating direction; and the first wall being integrally connected to the shielding shell.

[0009] Furthermore, the shielding shell includes a first shell and a second shell, the first shell and the second shell cooperate with each other in a second direction perpendicular to the docking direction and the first direction, the first wall is integrally connected to the first shell, the second shell is provided with a limiting groove, the first wall is located in the limiting groove, and the limiting groove restricts the movement of the first wall along the docking direction.

[0010] Furthermore, the first shell has a first protrusion, which is spaced apart from the first wall along the docking direction. The second shell has a positioning groove corresponding to the first protrusion, and the first protrusion is located in the positioning groove. A retaining part is provided on the second shell and located between the positioning groove and the limiting groove. The retaining part includes an internal section and a limiting section. The internal section is housed inside the first shell, and the limiting section is located outside the first shell, and the limiting section blocks the displacement of the first shell along the second direction.

[0011] Furthermore, the insulating body includes a plug-in cavity for accommodating the docking element. The insulating body includes a first slot for accommodating the signal terminal and a second slot for accommodating the grounding terminal. The first slot and the second slot are respectively connected to the plug-in cavity. A partition is provided between each of the first slot and each of the second slots. The contact portion of the signal terminal and the contact portion of the grounding terminal protrude from the first slot and the second slot respectively and are located in the plug-in cavity.

[0012] Furthermore, the shielding shell includes an end wall, two side walls disposed opposite to each other along the first direction, a first side plate, and a second side plate disposed opposite to the first side plate along a second direction, the second direction being perpendicular to the first direction and the docking direction. The two side walls, the first side plate, and the second side plate surround to form a receiving cavity. The signal terminal is received in the receiving cavity and is electrically isolated from the shielding shell. The signal terminal includes a contact portion that is conductive to the docking element. The second side plate has an opening for the contact portion to protrude. The end wall is integrally connected to the two side walls and the first side plate to close the end of the receiving cavity near the contact portion.

[0013] Furthermore, the signal terminal includes an end portion extending from the contact portion toward the mating element, and the second side plate includes a shielding portion located between the opening and the end wall along the mating direction, and shielding the end portion in the second direction. The shielding portion is integrally connected to the end wall, the two side walls, and the first side plate.

[0014] Furthermore, the signal terminal includes a contact portion that is conductive to the docking element and an end portion extending from the contact portion toward the docking element; along the first direction, the projection of the end portion is located within the projection of the grounding terminal.

[0015] Furthermore, the shielding shell includes a first shell and a second shell, which cooperate with each other along a second direction perpendicular to the docking direction and the first direction. The first shell has a first protrusion and a second protrusion. Along the first direction, the first protrusion and the second protrusion are located on the same side of the shielding shell and are spaced apart. The second shell is provided with a positioning groove corresponding to the first protrusion and the second protrusion to limit the displacement of the first shell along the docking direction. The first protrusion and the second protrusion are located in the two positioning grooves in a one-to-one correspondence. The first protrusion is provided with a first guiding slope on the side away from the second protrusion, and the second protrusion is provided with a second guiding slope on the side away from the second protrusion. The inclination directions of the first guiding slope and the second guiding slope are opposite.

[0016] Furthermore, the shielding shell includes a first shell and a second shell, which cooperate with each other along a second direction perpendicular to the docking direction and the first direction. The first shell has a first protrusion; the second shell is provided with a positioning groove corresponding to the first protrusion to limit the displacement of the first shell along the docking direction, and the first protrusion is located in the positioning groove. A retaining part is provided on the second shell and adjacent to the positioning groove. The retaining part includes an internal section and a limiting section. The internal section is received inside the first shell, and the limiting section is located outside the first shell, and the limiting section limits the displacement of the first shell along the second direction.

[0017] Furthermore, the shielding shell includes two sidewalls disposed opposite to each other along the first direction, and each grounding terminal includes a connecting portion, a contact arm extending from the connecting portion along the mating direction, and a conductive portion extending from the contact arm portion along the mating direction, wherein the connecting portion extends from the sidewall.

[0018] Furthermore, multiple conductive components are assembled within the insulating body along the mating direction, and viewed from the first direction, the shielding shell extends beyond the grounding terminal in the direction toward the mating element.

[0019] Furthermore, the two grounding terminals are arranged in a row along the first direction. Each grounding terminal includes a plate surface and a side surface. The plate surface is perpendicular to the first direction, and the side surface is parallel to the first direction. The plate surfaces of the two grounding terminals are arranged opposite each other along the first direction. The width of the plate surface along a second direction perpendicular to the first direction and the docking direction is greater than the width of the side surface along the first direction.

[0020] Furthermore, after the electrical connector and the mating element are plugged into each other, along the first direction, the projection of the grounding terminal is located within the projection of the shielding shell.

[0021] Furthermore, the docking element includes a grounding plate, which is electrically connected to the shielding shell.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Two grounding terminals are provided between the two shielding shells, creating a certain distance between them. This increases the distance between the signal terminals within the two shielding shells, thereby reducing crosstalk. Furthermore, each grounding terminal is connected to one shielding shell, and both grounding terminals are connected to a grounding conductor of the mating element. This allows the two shielding shells to achieve a stable connection through the mating element, eliminating the need for an additional structure in the electrical connector to connect the two shielding shells to each other. This provides better grounding and shielding while also enabling the miniaturization of the electrical connector.

[0024] The U-shaped connector provides sufficient support and rebound force to the contact arm, ensuring that the grounding terminal has sufficient support strength when the electrical connector is plugged into the mating element, and that the contact with the mating element is relatively stable due to the sufficient rebound force.

[0025] The shielding shell includes a first shell and a second shell, which cooperate with each other along a second direction. The first wall is integrally connected to the first shell, and the second shell is provided with a limiting groove. The first wall is located in the limiting groove. The limiting groove restricts the movement of the first wall along the docking direction. The limiting groove limits the movement of the first wall of the grounding terminal along the docking direction, so that when the grounding terminal is connected to the docking element and subjected to the pushing force of the docking element, it will not easily deform along the docking direction.

[0026] The first shell has a first protrusion, which is spaced apart from the first wall along the docking direction. The second shell has a positioning groove corresponding to the first protrusion, and the first protrusion is located inside the positioning groove. A retaining part is provided on the second shell and located between the positioning groove and the limiting groove. The retaining part includes an internal section and a limiting section. The internal section is housed inside the first shell, and the limiting section is located outside the first shell. The limiting section prevents the first shell from displacing along the second direction, so that the first shell and the second shell can mutually limit each other along the docking direction and the second direction, making the first shell and the second shell fit together accurately and connect stably.

[0027] The insulating body includes a first slot for receiving the signal terminal and a second slot for receiving the grounding terminal. The first slot and the second slot are respectively connected to the insertion cavity. A partition is provided between each of the first slot and each of the second slots. The partition can support and position the grounding terminal to prevent the position of the grounding terminal from shifting during repeated insertion and removal of the docking components.

[0028] The shielding shell includes an end wall, two side walls disposed opposite each other along the first direction, a first side plate, and a second side plate disposed opposite to the first side plate along a second direction, the second direction being perpendicular to the first direction and the mating direction. The two side walls, the first side plate, and the second side plate surround to form a receiving cavity. The signal terminal is housed in the receiving cavity and is electrically isolated from the shielding shell. The signal terminal includes a contact portion that is conductive to the mating element. The second side plate has an opening for the contact portion to protrude. The end wall is integrally connected to the two side walls and the first side plate to close the end of the receiving cavity near the contact portion, so that the shielding shell can also achieve a full shielding effect at the end near the contact portion, which can maximize the shielding of external interference and optimize the electrical characteristics of the electrical connector.

[0029] The signal terminal includes an end extending from the contact portion toward the mating element. When the signal terminal is connected to the mating element, an antenna effect is generally generated at the end, which may cause interference to adjacent signal terminals. To reduce this interference, the second side plate includes a shielding portion located between the opening and the end wall along the mating direction, and shielding the end in the second direction. The shielding portion is integrally connected to the end wall, the two side walls, and the first side plate, so that the end is located within the coverage area of ​​the shielding shell, which enhances the shielding effect and optimizes the electrical characteristics of the electrical connector.

[0030] The signal terminal includes a contact portion that is conductive to the docking element and an end portion extending from the contact portion toward the docking element. When the signal terminal is conductive to the docking element, an antenna effect is generally generated at the end portion, which may cause interference to adjacent signal terminals. In order to reduce this interference, the projection of the end portion is located within the projection of the grounding terminal along the first direction. This allows the grounding terminal to not only conduct the grounding path but also to shield the signal terminal over a larger area.

[0031] The first protrusion and the second protrusion are used to limit the relative position between the first shell and the second shell so that they can be engaged and fixed as desired. The first protrusion has a first guiding slope on the side opposite to the first protrusion, and the second protrusion has a second guiding slope on the side opposite to the second protrusion. The inclination directions of the first guiding slope and the second guiding slope are opposite, so that when the first shell and the second shell are engaged and fixed together, the guiding effect is stronger and it is easier for them to reach the desired relative position.

[0032] The shielding shell includes a first shell and a second shell, which cooperate with each other along a second direction perpendicular to the docking direction and the first direction. The first shell has a first protrusion; the second shell is provided with a positioning groove corresponding to the first protrusion to limit the displacement of the first shell along the docking direction, and the first protrusion is located in the positioning groove. A retaining part is provided on the second shell and adjacent to the positioning groove. The retaining part includes an internal section and a limiting section. The internal section is housed in the first shell, and the limiting section is located outside the first shell. The limiting section limits the displacement of the first shell along the second direction, so that the first shell and the second shell can mutually limit each other along the docking direction and the second direction, so that the first shell and the second shell cooperate accurately and are stably connected.

[0033] The grounding terminal extends from the side wall rather than being torn directly from it, thus avoiding gaps in the shielding shell caused by the torn grounding terminal, which would result in poor shielding performance at the gap locations.

[0034] During the assembly of the multiple conductive components into the insulating body along the mating direction, the shielding shell extends beyond the grounding terminal in the direction of the mating element, thus protecting the grounding terminal from damage caused by unintended impacts.

[0035] Two grounding terminals are arranged in a row along the first direction. Each grounding terminal includes a plate and a side surface. The plate is perpendicular to the first direction, and the side surface is parallel to the first direction. The plate surfaces of the two grounding terminals are arranged opposite each other along the first direction. The width of the plate surface along a second direction perpendicular to the first direction and the mating direction is greater than the width of the side surface along the first direction. In summary, the grounding terminal is a blank-type terminal. By having relatively wide plate surfaces facing each other, the width occupied by the grounding terminal in the first direction is reduced, which is beneficial to the miniaturization of the connector.

[0036] After the electrical connector and the mating element are plugged into each other, along the first direction, the projection of the grounding terminal is located within the projection of the shielding shell. The shielding shell can prevent the grounding terminal from being excessively deformed and damaged due to excessive plugging of the mating element.

[0037] In addition to the grounding path between the electrical connector and the mating element via the grounding terminal and the grounding conductor of the mating element, there is also a conductive path between the shielding plate and the grounding plate, which makes the shielding effect of the electrical connector and the mating element better.

[0048] Detailed Implementation

[0049] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0050] like Figures 1 to 9 As shown, the electrical connector 100 of the present invention defines the mating direction as the X-axis, the first direction as the Y-axis, and the second direction as the Z-axis.

[0051] like Figures 1 to 9 As shown, the electrical connector 100 of the present invention is plugged into a mating element 200 along a mating direction. The electrical connector 100 includes an insulating body 1 and a plurality of conductive components 2 arranged in four rows along the first direction. The portions of two adjacent conductive components 2 in the same row are staggered along the mating direction. The conductive components 2 are assembled on the insulating body 1 along the mating direction.

[0052] like Figure 1 and Figure 2As shown, the insulating body 1 includes a plug-in cavity 11 for accommodating the docking element 200. The insulating body 1 includes a plurality of first slots 12, a plurality of second slots 13, and a plurality of partitions 14. The first slots 12 and the second slots 13 are arranged alternately, that is, a second slot 13 is provided between every two first slots 12. The partitions 14 are provided between adjacent first slots 12 and second slots 13. The first slots 12 and the second slots 13 are all in communication with the plug-in cavity 11. Along the first direction, the width of the first slot 12 is greater than the width of the second slot 13.

[0053] like Figure 1 , Figure 3 and Figure 4 As shown, each of the conductive components 2 includes a shielding shell 21 and two signal terminals 23 housed within the shielding shell 21. The shielding shell 21 can be formed by a stretching process. The two signal terminals 23 are used to transmit a differential signal. Of course, in other embodiments, only one signal terminal 23 may be provided within the shielding shell 21. The signal terminal 23 and the shielding shell 21 are housed in the first groove 12. Further, in the first direction, two grounding terminals 24 are provided between every two shielding shells 21, and the two grounding terminals 24 are arranged in a row along the first direction. Each grounding terminal 24 includes a plate surface P1 and a side surface P2. The plate surface P1 is perpendicular to the first direction, and the side surface P2 is parallel to the first direction. The plate surfaces P1 of the two grounding terminals 24 are arranged opposite each other along the first direction. The width of the plate surface P1 along the second direction is greater than the width of the side surface P2 along the first direction. One grounding terminal 24 is integrally connected to one shielding shell 21. The two grounding terminals 24 are housed in a second groove 13. The conductive portions 243 of the two grounding terminals 24 protrude from the second groove 13 and are located in the insertion cavity 11, conducting with the same grounding conductor of the docking element 200. The contact portion 231 of the signal terminal 23 protrudes from the first groove 12 and is located in the insertion cavity 11, conducting with the signal conductor of the docking element 200. An end portion 232 extends from the contact portion 231 toward the docking element 200.

[0054] like Figure 3 , Figure 4 and Figure 7As shown, the shielding shell 21 includes an end wall 211, two side walls 212 disposed opposite to each other along the first direction, a first side plate 213, and a second side plate 214 disposed opposite to the first side plate 213 along a second direction. The two side walls 212, the first side plate 213, and the second side plate 214 surround to form a receiving cavity 223. The signal terminal 23 is received in the receiving cavity 223 and electrically isolated from the shielding shell 21. The second side plate 214 is provided with a contact portion 231 for the signal terminal 23 to protrude. The opening 216, the end wall 211 is integrally connected to the two side walls 212 and the first side plate 213 to close the end of the receiving cavity 223 near the contact portion 231. Further, the second side plate 214 is also provided with a shielding portion 215. Along the docking direction, the shielding portion 215 is located between the opening 216 and the end wall 211, and is integrally connected to the end wall 211, the two side walls 212 and the first side plate 213. Along the second direction, the shielding portion 215 shields the end portion 232. Of course, in order to meet the plugging requirements, the opening 216 can also be provided on the first side plate 213 according to the contact direction of the contact portion 231 of the signal terminal 23. When the opening 216 is provided on the first side plate 213, the end wall 211 is integrally connected with the two side walls 212 and the second side plate 214 to close the end of the receiving cavity 223 near the contact portion 231. Along the docking direction, the shielding portion 215 is located between the opening 216 and the end wall 211, and is integrally connected with the end wall 211, the two side walls 212 and the second side plate 214. Along the second direction, the shielding portion 215 shields the end portion 232.

[0055] like Figure 5 As shown, each of the shielding shells 21 includes a first shell 21a and a second shell 21b, which are separately disposed. The first shell 21a and the second shell 21b cooperate with each other along the second direction. Along the first direction, the first shell 21a has two first protrusions 217 and one second protrusion 218 on the same side. The second protrusion 218 and the two first protrusions 217 are spaced apart from each other. The second shell 21b has a positioning groove 220 corresponding to the two first protrusions 217 and the second protrusion 218. The two first protrusions 217 and the second protrusion 218 are respectively located in the positioning grooves 220 that correspond to them one by one, so as to limit the displacement of the first shell 21a and the second shell 21b along the docking direction.

[0056] Further reference Figure 5The second shell 21b further includes a retaining portion 221, which is located between two adjacent positioning grooves 220. The retaining portion 221 includes an inner section 2211 and a limiting section 2212. The inner section 2211 includes two protrusions 2211a (or other protrusions in other embodiments). The limiting section 2212 includes two opposing limiting surfaces 2212a. After the first shell 21a and the second shell 21b are fixed together along the second direction, the inner section 2211 is located inside the first shell 21a, the protrusions 2211a abut against the first shell 21a, and the limiting section 2212 is located outside the first shell 21a. The two limiting surfaces 2212a respectively block the first protrusion 217 and the second protrusion 218 to prevent relative displacement between the first shell 21a and the second shell 21b. Furthermore, the limiting section 2212 can also block the displacement of the first shell 21a along the second direction.

[0057] like Figure 5 and Figure 6 As shown, the first protrusion 217 has a first guiding slope 2171 on the side opposite to the second protrusion 218, and the second protrusion 218 has a second guiding slope 2181 on the side opposite to the second protrusion 218, and the first guiding slope 2171 and the second guiding slope 2181 have opposite inclination directions.

[0058] like Figure 3 and Figure 4 As shown, each grounding terminal 24 includes a U-shaped connecting portion 241 and a contact arm 242 extending from the U-shaped connecting portion 241. Each U-shaped connecting portion 241 includes a first wall 2411, a second wall 2412 spaced apart from the first wall 2411, and a bent portion 2413 connecting the first wall 2411 and the second wall 2412. The contact arm 242 extends from the second wall 2412 along the docking direction. The first wall 2411 is integrally connected to the first shell 21a, and the first wall 2411 is located in the limiting groove 219 to restrict the movement of the first wall 2411 along the docking direction. The first wall 2411 is located between the two first protrusions 217. A retaining portion 221 is also provided between the limiting groove 219 and the positioning groove 220 near the contact portion 231. Of course, in other embodiments, the connecting portion 241 can also be any other shape, such as extending directly from the side wall 212 by a vertical bend, instead of being U-shaped.

[0059] like Figure 6As shown, along the first direction, the projection of the end 232 is located within the projection of the grounding terminal 24; viewed from the first direction, the shielding shell 21 extends beyond the grounding terminal 24 toward the docking element 200.

[0060] like Figure 8 and Figure 9 As shown, after the electrical connector 100 and the mating element 200 are plugged into each other, along the first direction, the projection of the grounding terminal 24 is located within the projection of the shielding shell 21. The mating element 200 also includes a grounding piece 3, and the grounding piece 3 is electrically connected to the shielding shell 21.

[0061] In summary, the electrical connector 100 and its manufacturing method of the present invention have the following beneficial effects:

[0062] 1. Two grounding terminals 24 are provided between the two shielding shells 21, so that the two shielding shells 21 are spaced a certain distance apart. This increases the distance between the signal terminals 23 inside the two shielding shells 21, thereby reducing crosstalk. Furthermore, one grounding terminal 24 is connected to one shielding shell 21, and the two grounding terminals 24 are connected to a grounding conductor of the docking element 200, so that the two shielding shells 21 can achieve a stable connection through the docking element 200. There is no need to set an additional structure in the electrical connector 100 to connect the two shielding shells 21 to each other. The grounding shielding effect is better, and the miniaturization of the electrical connector 100 can also be met.

[0063] 2. The U-shaped connecting portion 241 provides sufficient support and rebound force to the contact arm 242, ensuring that the grounding terminal 24 has sufficient support strength when the electrical connector 100 is inserted into the mating element 200, and that its contact with the mating element 200 is relatively stable due to sufficient rebound force.

[0064] 3. The shielding shell 21 includes a first shell 21a and a second shell 21b. The first shell 21a and the second shell 21b cooperate with each other along the second direction. The first wall 2411 is integrally connected with the first shell 21a. The second shell 21b is provided with a limiting groove 219. The first wall 2411 is located in the limiting groove 219. The limiting groove 219 restricts the movement of the first wall 2411 along the docking direction. The limiting groove 219 limits the movement of the first wall 2411 of the grounding terminal 24 along the docking direction, so that when the grounding terminal 24 is connected to the docking element 200 and is subjected to the pushing force of the docking element 200, it will not easily deform along the docking direction.

[0065] 4. The first shell 21a has a first protrusion 217, which is spaced apart from the first wall 2411 along the docking direction. The second shell 21b has a positioning groove 220 corresponding to the first protrusion 217, and the first protrusion 217 is located inside the positioning groove 220. A retaining part 221 is provided on the second shell 21b and located between the positioning groove 220 and the limiting groove 219. The retaining part 221 includes an internal section 2211 and a limiting section 2212. The internal section 2211 is received inside the first shell 21a, and the limiting section 2212 is located outside the first shell 21a. The limiting section 2212 blocks the displacement of the first shell 21a along the second direction, so that the first shell 21a and the second shell 21b can be mutually limited along the docking direction and the second direction, so that the first shell 21a and the second shell 21b fit together accurately and are connected stably.

[0066] 5. The insulating body 1 includes a first slot 12 for receiving the signal terminal 23 and a second slot 13 for receiving the grounding terminal 24. The first slot 12 and the second slot 13 are respectively connected to the insertion cavity 11. A partition 14 is provided between each first slot 12 and each second slot 13. The partition 14 can support and position the grounding terminal 24 to prevent the position of the grounding terminal 24 from shifting during repeated insertion and removal of the docking element 200.

[0067] 6. The shielding shell 21 includes an end wall 211, two side walls 212 disposed opposite to each other along the first direction, a first side plate 213, and a second side plate 214 disposed opposite to the first side plate 213 along a second direction, the second direction being perpendicular to the first direction and the mating direction. The two side walls 212, the first side plate 213, and the second side plate 214 surround to form a receiving cavity 223. The signal terminal 23 is received in the receiving cavity 223 and is electrically isolated from the shielding shell 21. The signal terminal 23 includes a contact portion 231 that is connected to the mating element 200. The second side plate 214 is provided with an opening 216 for the contact portion 231 to protrude. The end wall 211 is integrally connected with the two side walls 212 and the first side plate 213 to close the end of the receiving cavity 223 near the contact portion 231, so that the shielding shell 21 can also achieve a full shielding effect at the end near the contact portion 231, which can maximize the shielding of external interference and optimize the electrical characteristics of the electrical connector 100.

[0068] 7. The signal terminal 23 includes an end portion 232 extending from the contact portion 231 toward the mating element 200. When the signal terminal 23 is connected to the mating element 200, an antenna effect is generally generated at the end portion 232, which may cause interference to the adjacent signal terminals 23. In order to reduce this interference, the second side plate 214 includes a shielding portion 215. Along the mating direction, the shielding portion 215 is located between the opening 216 and the end wall 211, and shields the end portion 232 in the second direction. The shielding portion 215 is integrally connected with the end wall 211, the two side walls 212, and the first side plate 213, so that the end portion 232 is located within the coverage area of ​​the shielding shell 21, which enhances the shielding effect and optimizes the electrical characteristics of the electrical connector 100.

[0069] 8. The signal terminal 23 includes a contact portion 231 that is connected to the docking element 200 and an end portion 232 extending from the contact portion 231 toward the docking element 200. When the signal terminal 23 is connected to the docking element 200, an antenna effect is generally generated at the end portion 232, which will cause interference to the adjacent signal terminal 23. In order to reduce this interference, the projection of the end portion 232 is located within the projection of the grounding terminal 24 along the first direction. This allows the grounding terminal 24 to not only conduct the grounding path, but also to shield the signal terminal 23 over a larger area.

[0070] 9. The first protrusion 217 and the second protrusion 218 are used to limit the relative position between the first shell 21a and the second shell 21b, so that they are engaged and fixed as desired. The first protrusion 217 has a first guide slope 2171 on the side opposite to the first protrusion 217, and the second protrusion 218 has a second guide slope 2181 on the side opposite to the second protrusion 218. The inclination directions of the first guide slope 2171 and the second guide slope 2181 are opposite, so that when the first shell 21a and the second shell 21b are engaged and fixed, the guiding effect is stronger, and it is easier for them to reach the desired relative position.

[0071] 10. The shielding shell 21 includes a first shell 21a and a second shell 21b, which are mutually engaged along a second direction perpendicular to the docking direction and the first direction. The first shell 21a has a first protrusion 217; the second shell 21b is provided with a positioning groove 220 corresponding to the first protrusion 217 to limit the displacement of the first shell 21a along the docking direction, and the first protrusion 217 is located within the positioning groove 220; a retaining part 221 is provided on the second shell 21a. The retaining part 221 is disposed on 1b and adjacent to the positioning groove 220. The retaining part 221 includes an inner section 2211 and a limiting section 2212. The inner section 2211 is housed inside the first shell 21a, and the limiting section 2212 is located outside the first shell 21a. The limiting section 2212 displaces the first shell 21a along the second direction, so that the first shell 21a and the second shell 21b can mutually limit each other along the docking direction and the second direction, so that the first shell 21a and the second shell 21b fit together accurately and are connected stably.

[0072] 11. The grounding terminal 24 is formed by extending from the side wall 212 as a whole, rather than by tearing it directly from the side wall 212, so as to avoid the shielding effect of the shielding shell 21 being poor at the position of the gap caused by the grounding terminal 24 formed by tearing.

[0073] 12. During the assembly of the plurality of conductive components 2 into the insulating body 1 along the mating direction, since the shielding shell 21 extends beyond the grounding terminal 24 in the direction of the mating element 200, the shielding shell 21 can protect the grounding terminal 24 from damage caused by unintended impacts.

[0074] 13. Two grounding terminals 24 are arranged in a row along the first direction. Each grounding terminal 24 includes a plate surface P1 and a side surface P2. The plate surface P1 is perpendicular to the first direction, and the side surface P2 is parallel to the first direction. The plate surfaces P1 of the two grounding terminals 24 are arranged opposite each other along the first direction. The width of the plate surface P1 along the second direction perpendicular to the first direction and the mating direction is greater than the width of the side surface P2 along the first direction. In summary, the grounding terminal 24 is a blank-type terminal. By having wider plate surfaces P1 facing each other, the width occupied by the grounding terminal 24 in the first direction is reduced, which is beneficial to the miniaturization of the connector.

[0075] 14. After the electrical connector 100 and the mating element 200 are plugged into each other, along the first direction, the projection of the grounding terminal 24 is located within the projection of the shielding shell 21. The shielding shell 21 can prevent the grounding terminal 24 from being excessively deformed and damaged due to excessive plugging of the mating element 200.

[0076] 15. In addition to the grounding path through which the grounding terminal 24 connects the electrical connector 100 and the mating element 200 to the grounding conductor, there is also a conductive path between the shielding plate and the grounding plate 3, which makes the shielding effect of the electrical connector 100 and the mating element 200 better.

Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
