Through the above description, we can understand the structure of this technology, and according to the corresponding cooperation of this structure, it can achieve smaller volume, higher structural strength, lower overall height after plugging, and less capacitance effect. The advantages of better high-frequency characteristics and reduced characteristic impedance will be explained in detail below.

In this embodiment, the arrangement of the elastic parts in the transmission conductor group 3 is a first differential elastic part 311, a second differential elastic part 321, a third differential elastic part 331, a fourth differential elastic part 341, and a fifth differential elastic part. The part 351, the sixth differential elastic part 361, the seventh differential elastic part 371, and the eighth differential elastic part 381, so that the arrangement sequence of the elastic parts can be the same as the specifications of the RJ45 female connector, so as to comply with the RJ45 female connector The Association Regulations.

However, because the third differential elastic portion 331 and the sixth differential elastic portion 361 are in order to comply with the association specifications of the RJ45 female connector, their positions cannot be changed, so they cannot be coupled to each other, which tends to produce higher characteristic impedance. Therefore, the shielding shell 1 will be provided with a first ground plate body 11 corresponding to the third differential elastic portion 331 and a second ground plate body 12 corresponding to the sixth differential elastic portion 361 to perform grounding coupling with each other. Thereby reducing the characteristic impedance, and the first A ground plate body 11 is a metal elastic piece formed by the shielding shell 1 extending inwardly, and its shape and position will correspond to the third differential elastic portion 331, and the second grounding plate body 12 is formed by the shielding shell 1 inwardly. And the shape and position of the metal elastic sheet corresponding to the sixth differential elastic portion 332. Furthermore, the first ground sheet body 11 will pass the limiting effect of the first sheet body limiting portion 211, and the second ground sheet body 12 will pass The limiting effect of the second sheet limiting portion 212 limits the heights of the first ground sheet 11 and the second ground sheet 12, and at the same time cooperates with the limitations of the third conductor limiting portion 233 and the sixth conductor limiting portion 236 This effect restricts the swing distance of the third and sixth differential elastic portions 331 and 361, thereby preventing the first and second ground plates 11 and 12 from the third and sixth differential elastic portions 331 and 361. The parts 361 are in contact with each other to prevent the occurrence of a short circuit.

The third differential holding portion 332 is then used to cross the fourth differential holding portion 342 and the fifth differential holding portion 352, and the bending effect of the first side bending portion 335 and the second side bending portion 365 is used to make the third differential signal The lengths of the transmission conductor 33 and the sixth differential signal transmission conductor 36 are almost equal, so that the third differential welding portion 334 and the fourth differential welding portion 344 can be arranged adjacently.

Therefore, as far as the welding ends of the transmission conductor group 3 are concerned, their arrangement is the first differential welding portion 314, the second differential welding portion 324, the fourth differential welding portion 344, the fifth differential welding portion 354, and the third differential welding portion. 334, the sixth differential welding part 364, the seventh differential welding part 374, and the eighth differential welding part 384, that is, the first differential welding part 314 and the second differential welding part 324, the fourth differential welding part 344 and the fifth difference The welding part 354, the third differential welding part 334 and the sixth differential welding part 364, the seventh differential welding part 374 and the eighth differential welding part 384 are arranged adjacent to each other, thereby reducing the influence caused by the capacitance effect and coupling the terminals The effect is better, and the performance of high-frequency characteristics is improved at the same time, and the manufacturing cost can be effectively controlled (without combining the conventional filter module), and the problem of electromagnetic interference can be reduced at the same time.

At the same time, in order to prevent the third differential holding portion 332 and the sixth differential holding portion 362 from touching the fourth differential holding portion 342 or the first side bending portion 335 and the second side bending portion 365 due to the bending effect The five-differential holding portion 352 may be short-circuited, and the bending angles of the third differential bending portion 333 and the sixth differential bending portion 363 will be larger than those of the first differential bending portion 313, the second differential bending portion 323, and the first differential bending portion 313. The four differential bending portion 343, the fifth differential bending portion 353, the seventh differential bending portion 373, and the eighth differential bending portion 383, so that the third differential holding portion 332 and the sixth differential holding portion 362 are located at the first A differential holding portion 312, a second differential holding portion 32 2. At the upper side of the fourth difference holding portion 342, the fifth difference holding portion 352, the seventh difference holding portion 372, and the eighth difference holding portion 382, so as to achieve a mutually staggered avoidance effect.

Furthermore, the first differential signal transmission conductor 31 will be limited by the first conductor limiting portion 231, the second differential signal transmission conductor 32 will be limited by the second conductor limiting portion 232, and the third differential signal will be transmitted. The conductor 33 is limited by the third conductor limiting portion 233, the fourth differential signal transmission conductor 34 is limited by the fourth conductor limiting portion 234, and the fifth differential signal transmission conductor 35 is limited by the fifth conductor. The position portion 235 performs a limiting action, the sixth differential signal transmission conductor 36 is limited by the sixth conductor limiting portion 236, and the seventh differential signal transmission conductor 37 is limited by the seventh conductor limiting portion 237. The eighth differential signal transmission conductor 38 will be limited by the eighth conductor limiting portion 238, so that in the transmission conductor set 3, only the elastic portion will be displaced due to the male and female butt joints, and the rest will be covered by the first insulating colloid. 21 and the second insulating colloid 22 perform a position limiting action, thereby preventing the transmission conductor group 3 from being short-circuited, and can once again enhance the effect of position avoidance.

Please also refer to Figures 11 to 14 at the same time, which are the three-dimensional view to the use state diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment and the above-mentioned embodiment are The similarities and minor differences, as can be clearly seen from the figure, the shielding shell 1a will have a male connector 13a and a buckle structure 14a that partially shields the male connector 13a, through which the male connector 13a can be used to fix the male connector Connector 4a. In this embodiment, the male connector 4a has a press-fit structure 41a, and the press-fit structure 41a includes an elastic arm 42a corresponding to the male coupling opening 13a, and an elastic arm 42a formed at one end of the elastic arm 42a. When the pressing portion 43a and two pressing portions 44a formed on different sides of the pressing portion 43a and mutually abutted against the buckle structure 14a, and the electrical connector 100a is combined with the male connector 4a, The buckle holding portion 44a and the buckle structure 14a are in a horizontal state. Furthermore, in this embodiment, the shielding shell 1a and the insulating gel 2a form a plug-in interface 45a for the male connector 4a. The space for insertion, the male coupling port 13a is a notch formed on the upper surface of the shielding shell 1a. The opening direction of the male coupling port 13a is the same as that of the socket 45a, so that after the male connector 4a is inserted, the male coupling The bottom of the opening 13a presses the elastic arm 42a, and the internal space of the male coupling port 13a is used to accommodate the pressing portion 43a. As for the buckle structure 14a, the shielding shell 1a on both sides of the male coupling port 13a slot is inserted from the adjacent The stopper structure in which the limiting portion 181a at the interface 45a extends into the male coupling port 13a to partially shield the action of the male coupling port 13a. When the male connector 4a is inserted, the card is used The buckle structure 14a resists the pressing portion 44a to prevent the pressing portion 44a from loosening due to the elastic force of the elastic arm 42a when no force is applied to the pressing portion 43a, thereby achieving the use of a metal shielding shell 1a replaces the insulating glue made of plastic material to fix the male connector 4a. In addition, because the structural strength of metal is much greater than that of plastic, the structural strength of the buckle structure 14a can be improved. Even if the combination of the buckle structure 14a and the press-buckle resisting portion 44a is challenged due to improper operation by the user, the priority damage is also The low-cost and easy-to-replace press-buckle abutment portion 44a will not cause damage to the electrical connector 100a.

In addition, because the shielding shell 1a has provided the plugging space and the fixing structure of the male connector 4a, the extra space occupied by the insulating gel 2a can be saved, and the electrical connector can be effectively reduced while providing the same effect. The volume of 100a itself, specifically, the height of the shielding shell 1a can be reduced to less than 10.55 millimeters (mm), and the width can also be reduced to less than 12.6 millimeters (mm), even because the male coupling port 13a presses the strength of the elastic arm 42a Compared with the conventional use of insulators, the compression strength is better, so the tilting height of the pressing portion 43a can be reduced, and the height of the buckle structure 14a can be almost leveled with the height of the buckle resisting portion 44a, and the insertion is reduced. The overall height after the connection. Moreover, in this embodiment, the side wall of the shielding shell 1a is also formed with at least one resisting and limiting portion 15a, and the resisting and limiting portion 15a is a protrusion formed by recessing the shielding shell 1a as an example. In this way, when the male connector 4a is inserted, the resisting and limiting portion 15a of the side wall of the shielding shell 1a can be used to limit the insertion depth of the male connector 4a, and at the same time, prevent excessive insertion force from damaging the insulating gel 2a.

Moreover, in this embodiment, the shielding shell 1a will have at least one gel limiting portion 16a and at least one gel anti-dropping portion 17a. The gel limiting portion 15a is a protrusion formed by the shielding shell 1a recessed inwardly, and It is located at the side adjacent to the plug interface 45a and can be used to prevent the insulating glue 2a from moving, thereby fixing the position of the insulating glue 2a to prevent the insulating glue 2a from lifting up on the side adjacent to the plug interface 45a and disturbing the male The plugging action of the head connector 4a, and the gel anti-dropping portion 17a is also a convex block formed by the shielding shell 1a recessed inward, and is located at one side of the dissimilar gel limiting portion 16a, and can also be used to fix the insulating gel 2a, thereby preventing the insulating glue 2a from being taken out of the shielding shell 1a when the male connector 4a is unplugged.

In addition, the shielding shell 1a has at least one shell recess 18a formed on the shielding shell 1a, at least one limiting portion 181a formed on the shielding shell 1a and located at the end of the shell recess 18a, At least one perforated portion 182a formed on the side of the limiting portion 181a and connected to the housing recess 18a, and at least one light guide auxiliary portion 18 provided on the side of the shielding housing 1a 3a, where the housing recess 18a on the shielding housing 1a is formed by bending the top and side surfaces of the shielding housing 1a inwardly to form an accommodating space for the LED light guide strip 51a. In this embodiment In this case, the LED5a will be arranged on the circuit substrate 6a, and the LED light guide strip 51a can be fixed by the limit parts 181a at both ends, and the LED light guide strip 51a can pass through the perforated part 182a and be connected to the light guide auxiliary part 183a.
