Through the above description, the structure of the present technology can be understood, and according to the corresponding matching of the structure, the advantages of smaller volume, higher structural strength, lower overall height after plugging, less influence of capacitance effect, better high-frequency characteristics, reduced characteristic impedance, etc. can be achieved, and the detailed description will be described below.
In this embodiment, the elastic portions in the transmission conductor set 3 are arranged in the order of the first differential elastic portion 311, the second differential elastic portion 321, the third differential elastic portion 331, the fourth differential elastic portion 341, the fifth differential elastic portion 351, the sixth differential elastic portion 361, the seventh differential elastic portion 371, and the eighth differential elastic portion 381, so that the arrangement order of the elastic portions can be the same as the specification of the RJ45 female connector, so as to conform to the association specification of the RJ45 female connector.
However, since the third differential elastic portion 331 and the sixth differential elastic portion 361 are not able to change their positions in order to comply with the association specification of the RJ45 female connector, they cannot be coupled to each other, and thus a high characteristic impedance is easily generated, the shielding case 1 is provided with a first grounding sheet 11 corresponding to the third differential elastic portion 331 and a second grounding sheet 12 corresponding to the sixth differential elastic portion 361, which are mutually coupled to each other to reduce the characteristic impedance, the first grounding sheet 11 is a metal elastic sheet formed by extending the shielding case 1 inward and having a shape and a position corresponding to the third differential elastic portion 331, the second grounding sheet 12 is a metal elastic sheet formed by extending the shielding case 1 inward and having a shape and a position corresponding to the sixth differential elastic portion 332, and furthermore, the first grounding sheet 11 passes through the limit effect of the first sheet limiting portion 211, the second ground plate 12 limits the heights of the first ground plate 11 and the second ground plate 12 by the limiting effect of the second plate limiting portion 212, and limits the swing distances of the third differential elastic portion 331 and the sixth differential elastic portion 361 by the limiting effect of the third conductor limiting portion 233 and the sixth conductor limiting portion 236, thereby preventing the first ground plate 11 and the second ground plate 12 from contacting the third differential elastic portion 331 and the sixth differential elastic portion 361, and preventing a short circuit.
The third differential holding portion 332 is disposed over the fourth differential holding portion 342 and the fifth differential holding portion 352, and the bending effect of the first side bent portion 335 and the second side bent portion 365 is used to make the lengths of the third differential signal transmission conductor 33 and the sixth differential signal transmission conductor 36 almost equal, so that the third differential soldering portion 334 and the fourth differential soldering portion 344 are disposed adjacently.
Therefore, for the welding ends of the transmission conductor set 3, the first differential welding portion 314, the second differential welding portion 324, the fourth differential welding portion 344, the fifth differential welding portion 354, the third differential welding portion 334, the sixth differential welding portion 364, the seventh differential welding portion 374 and the eighth differential welding portion 384 are arranged in sequence, so that the first differential welding portion 314 and the second differential welding portion 324, the fourth differential welding portion 344 and the fifth differential welding portion 354, the third differential welding portion 334 and the sixth differential welding portion 364, and the seventh differential welding portion 374 and the eighth differential welding portion 384 are arranged adjacent to each other in pairs, thereby reducing the influence caused by the capacitance effect, improving the terminal coupling effect, improving the performance of the high-frequency characteristic, effectively controlling the manufacturing cost (without combining with a conventional filter module), and reducing the problem of electromagnetic interference.
Meanwhile, in order to prevent the third differential holding portion 332 and the sixth differential holding portion 362 from generating a short circuit due to the bending effect of the first side bent portion 335 and the second side bent portion 365 by touching the fourth differential holding portion 342 or the fifth differential holding portion 352, the bending angle of the third differential bending portion 333 and the sixth differential bending portion 363 is larger than that of the first differential bending portion 313, the second differential bending portion 323, the fourth 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 upper side of the first differential holding portion 312, the second differential holding portion 322, the fourth differential holding portion, the fifth differential holding portion 352, the seventh differential holding portion 372, and the eighth differential holding portion 382, thereby achieving the staggered avoiding effect.
Furthermore, the first differential signal transmission conductor 31 is limited by the first conductor limiting portion 231, the second differential signal transmission conductor 32 is limited by the second conductor limiting portion 232, the third differential signal transmission 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, the fifth differential signal transmission conductor 35 is limited by the fifth conductor limiting portion 235, the sixth differential signal transmission conductor 36 is limited by the sixth conductor limiting portion 236, the seventh differential signal transmission conductor 37 is limited by the seventh conductor limiting portion 237, the eighth differential signal transmission conductor 38 is limited by the eighth conductor limiting portion 238, so that only the elastic portion of the transmission conductor set 3 will be displaced when the male and female portions are connected, and the rest portions will be limited by the first and second insulating colloids 21 and 22, thereby preventing the transmission conductor set 3 from generating a short circuit and enhancing the avoiding effect again.
As shown in fig. 11 to 14, it is clear that the embodiment is substantially the same as the above embodiment, and as can be seen clearly from the figure, the shielding shell 1a has a male coupling opening 13a and a locking structure 14a partially covering the male coupling opening 13a, so that the male connector 4a can be fixed through the male coupling opening 13 a. In this embodiment, the male connector 4a is defined to have a pressing structure 41a, the pressing structure 41a includes a resilient arm 42a correspondingly coupled to the male coupling opening 13a, a pressing portion 43a formed at one end of the resilient arm 42a, and two pressing and retaining portions 44a formed at opposite sides of the pressing portion 43a and mutually retained by the latching structure 14a, and when the electrical connector 100a is coupled to the male connector 4a, the pressing and retaining portions 44a and the latching structure 14a are horizontal, further, in this embodiment, the shielding shell 1a and the insulating colloid 2a together form a plug opening 45a as a space for inserting the male connector 4a, the male coupling opening 13a is a notch formed on an upper surface of the shielding shell 1a, an opening direction of the male coupling opening 13a is the same as that of the plug opening 45a, so that after the male connector 4a is inserted, the bottom of the male coupling opening 13a is used to press the elastic arm 42a tightly, the inner space of the male coupling opening 13a is used to accommodate the pressing portion 43a, the fastening structure 14a is the shielding shell 1a at both sides of the notch of the male coupling opening 13a, and the limit portion 181a adjacent to the insertion opening 45a is used as a stopper structure extending into the male coupling opening 13a, so that the action of partially shielding the male coupling opening 13a is performed, when the male connector 4a is inserted, the fastening structure 14a is used to abut against the pressing and fastening portion 44a, thereby preventing the pressing and fastening portion 44a from loosening due to the elastic force of the elastic arm 42a under the condition that the pressing portion 43a is not applied with force, and thus achieving the effect of fixing the male connector 4a by replacing the insulating adhesive made of plastic material with the shielding shell 1a made of metal material. Since the structural strength of the metal is much stronger than that of the plastic, the structural strength of the latch structure 14a can be improved, and even if the combination of the latch structure 14a and the press-latching supporting portion 44a is challenged due to improper operation of a user, the press-latching supporting portion 44a which is damaged preferentially is also lower in cost and easy to replace, and the electric connector 100a cannot be damaged.
In addition, because the plug space and the fixing structure of the male connector 4a are provided by the shielding shell 1a, the extra space occupied by the insulating colloid 2a can be saved, and the volume of the electrical connector 100a can be effectively reduced under the condition of providing the same effect, specifically, the height of the shielding shell 1a can be reduced to be less than 10.55 mm, the width can be reduced to be less than 12.6 mm, even the strength of the elastic arm 42a pressed by the male connector combining port 13a is better than the strength pressed by the conventional insulator, the tilting height of the pressing part 43a can be reduced, and the height of the buckling structure 14a and the height of the pressing and buckling supporting part 44a are almost horizontal, so that the overall height after plug is reduced. In addition, in the embodiment, at least one abutting limiting portion 15a is further formed on the side wall of the shielding shell 1a, and the abutting limiting portion 15a is a convex block formed by the shielding shell 1a being recessed inwards as an example, so that when the male connector 4a is inserted, the abutting limiting portion 15a on the side wall of the shielding shell 1a can be used to limit the inserting depth of the male connector 4a, and meanwhile, the inserting force is prevented from being too strong to damage the insulating colloid 2 a.
In the embodiment, the shielding shell 1a has at least one colloid-limiting portion 16a and at least one colloid-retaining portion 17a, the colloid-limiting portion 16a is a convex block formed by recessing the shielding shell 1a inward, and is located at a side adjacent to the insertion opening 45a, and can be used for preventing the insulating colloid 2a from moving, so as to fix the position of the insulating colloid 2a, and prevent the side of the insulating colloid 2a adjacent to the insertion opening 45a from tilting upward and interfering with the insertion operation of the male connector 4a, and the colloid-retaining portion 17a is also a convex block formed by recessing the shielding shell 1a inward, and is located at a side of the different colloid-limiting portion 16a, and can also be used for fixing the insulating colloid 2a, thereby preventing the insulating colloid 2a from being taken out of the shielding shell 1a when the male connector 4a is removed.
And the shielding shell 1a has at least one shell concave portion 18a concavely formed on the shielding shell 1a, at least one position-limiting portion 181a formed on the shielding shell 1a and located at the end of the shell concave portion 18a, at least one through hole portion 182a formed at one side of the position-limiting portion 181a and communicated with the shell concave portion 18a, and at least one light guiding auxiliary portion 183a located at the side of the shielding shell 1a, wherein the shell concave portion 18a on the shielding shell 1a is formed by bending and recessing the top surface and the side surface of the shielding shell 1a inward to form an accommodating space for the LED light guiding strip 51a, in this embodiment, the LED 5a is disposed on the circuit substrate 6a, and the LED light guiding strip 51a can be fixed by the position-limiting portions 181a at both ends, and the LED strip 51a passes through the through hole portion 182a to be connected to the light guiding auxiliary portion 183a and extends downward to the LED 5a, thereby allowing the LED 5a to guide the light source to the upper side of the shield case 1 a.
The above description is only a preferred embodiment of the present invention, and not so is to be limited to the scope of the present invention, so that the simple modification and equivalent structural changes made by the contents of the specification and drawings should be considered as included in the scope of the present invention.
