The present invention relates to an electrical connector, and more particularly to an electrical connector having a good shielding effect.
The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
Chinese Patent CN201320378153.0 discloses, in paragraph [0008] of the specification, an electrical connector, which includes an insulating body 1, a first terminal group 2 retained to the insulating body 1, and a shielding member 4. The insulating body 1 includes a base and a tongue 12 extending forward. The tongue 12 has a first surface 121 and a second surface 122 disposed opposite to each other. The first terminal group 2 is exposed to the first surface 121, and the shielding member 4 is disposed at the tongue 12 and located between the first surface 121 and the second surface 122. The first terminal group 2 includes a grounding terminal 21. The grounding terminal 21 is provided with a contact portion 211 protruding towards the shielding member 4 and contacting the shielding member 4. Paragraph [0020] discloses that the shielding member 4 is integrally formed at a mating plate 13, the first terminal group 2 and a second terminal group 3 are oppositely assembled to the mating plate 13 and then assembled forward to an assembly frame 14 together with the mating plate 13, forming the insulating body 1. However, when the electrical connector of such a structure is used for transmitting high-speed signals, electromagnetic radiation produced by the first terminal group and the second terminal group is easy to leak backward, resulting in that crosstalk is produced during signal transmission at tails of the first terminal group and the second terminal group, which affects signal transmission quality of the electrical connector. In addition, terminals of such an electrical connector are simultaneously assembled to the first surface and the second surface, and as there are more terminals and the tongue is smaller, operations are inconvenient, which easily results in that the terminals are not mounted firmly and tilt upward, damaging the whole electrical connector.

In this embodiment, the second height H2 is more than or equal to 0.01 mm and less than or equal to 0.05 mm. In other embodiments, the second height H2 may be more than or equal to 0.03 mm and less than or equal to 0.06 mm.

To sum up, the electrical connector 100 according to certain embodiments of the present invention has the following beneficial effects.
(1) The first insulating post 141 is located between the two second insulating posts 142, and a dimension of each second insulating post 142 in the front-rear direction is larger than a dimension of the first insulating post 141, which may increase an abutting area of the second insulating posts 142 and the middle grounding sheet 3, and thereby may firmly retain the middle grounding sheet 3 in the insulating body 1 and further firmly retain the middle grounding sheet 3 in the electrical connector 100, and avoiding the middle grounding sheet 3 from being displaced in an insertion and extraction process of the electrical connector 100 and the mating connector 200. The first clearance C1 formed between the first position limiting surface 5101 and the first wall surface 2031 may be controlled within a range of 0.001 mm to 0.059 mm, such that the fit clearance in the vertical direction is reduced during insertion of the mating connector 200 and the electrical connector 100, an vertical shake amplitude of the mating connector 200 in the insertion space 501 is reduced, the mating connector 200 may mate with the electrical connector 100 firmly, and the vertical shake amplitude of the retaining portion 2040 in the insertion space 501 is also reduced. In the electrical connector 100 according to certain embodiments of the present invention, the displacement of the middle grounding sheet 3 is avoided, and the vertical shake amplitude of the retaining portion 2040 in the insertion space 501 is reduced, thus ensuring the electrical abutting between the retaining elastic sheet 204 and the middle grounding sheet 3.
(2) The first protruding portion 510 is strip shaped, extends forward beyond the upper plate surface 242 of the high-speed signal terminal S in the upper row and the lower plate surface 252 of the high-speed signal terminal S in the lower row, and extends backward beyond the first abutting position 2420 and the second abutting position 2520, such that in the process where the contact terminal 202 in the upper row starts abutting the upper plate surface 242 to reach the first abutting position 2420 and the contact terminal 202 in the lower row reaches the second abutting position 2520, the first protruding portion 510 keeps a position limiting action in the vertical direction on the first wall surface 2031, which reduces shakes of the electrical connector 100 in the vertical direction, enables good mating stability between the contact terminals 202 and the high-speed signal terminals S, and further facilitates a high-frequency property of the electrical connector 100.
(3) When the mating connector 200 is inserted into the insertion space 501, the mating connector 100 passes through the first vertical surface F at first to reduce shakes of the mating connector 200 in the vertical direction and the left-right direction and result in stability of the insertion process of the electrical connector 100 and the mating connector 200, then passes through the edge 311 to prevent the edge 311 from scratching the mating connector 200 during improper mating, and finally mates with the tongue 12 to achieve a stable mating effect, a good positioning effect and favorability for high-frequency transmission performance of the electrical connector 100 and the mating connector 200.
(4) The upper grounding sheet 41 has the extending portion 412 covering an upper surface of the base 11, and the lower grounding sheet 42 has the stopping portion 422 clinging to a lower surface of the plastic block 13, which increases coverage of the inner metal shell 4, more effectively prevents crosstalk caused by that electromagnetic radiation in the insertion space 501 leaks backward to interfere tails of the terminals 2 during high-speed signal transmission of the electrical connector 100, and improves signal transmission quality of the electrical connector 100.
(5) The middle grounding sheet 3 has the vertical portion 32 located between the first rear portion 212 and the second rear portion 222, which effectively shields telecommunication interference between the first rear portions 212 and the second rear portions 222, and enhances signal transmission stability of the electrical connector 100.
(6) The insulating body 1 is formed by assembling the base 11, the tongue 12 and the plastic block 13, which reduces the difficulty of integrally forming the insulating body 1, improves the manufacturing speed of the insulating body 1, and saves the manufacturing cost of the electrical connector 100.
(7) During assembly, the tongue 12 adopts a hot melting method to retain the terminals 2, which makes the terminals 2 unlikely to tilt upward on the tongue 12, and prolongs the service life of the electrical connector 100.
The foregoing description of the exemplary embodiments of the invention has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise forms disclosed.
