Description

Electrical connector

[ technical field ] A method for producing a semiconductor device

The present invention relates to an electrical connector, and more particularly, to an electrical connector with a good shielding effect.

[ background of the utility model ]

An electrical connector includes an upper row of terminals and a lower row of terminals located below the upper row of terminals, where the upper row of terminals has a plurality of first ground terminals, each of the first ground terminals has a first contact portion and a first fixing portion and a first extending portion located behind the first contact portion and forming an angle with each other. The lower row of terminals has a plurality of second ground terminals, each of which has a second contact portion, a second fixing portion and a second extending portion, the second fixing portion and the second extending portion are located behind the first contact portion and are arranged at an angle with each other. A shield plate is located behind the first and second contact portions and between the upper and lower rows of terminals, and the shield plate is not in contact with the first and second ground terminals. In this manner, the shield plate can shield signal interference between the upper row of terminals and the lower row of terminals.

However, with the development of electrical connectors, the electrical connectors have been transmitting signals at 12Gbp or more, so the high frequency performance of the electrical connectors is continuously required. Since the shield plate is located behind the first contact portion and the second contact portion and between the upper row of terminals and the lower row of terminals, the shield plate is not in contact with the first ground terminal and the second ground terminal. This causes the potential between the first ground terminals and the second ground terminals to be different, which affects the grounding effect of the first ground terminals and the second ground terminals, and thus the high-frequency performance of the electrical connector. Furthermore, it is known from a calculation formula of wavelength that, in a certain length range, the amplitude of the signal transmitted through the first ground terminal increases with the distance from the first contact portion, the amplitude of the signal transmitted through the second ground terminal increases with the distance from the second contact portion, and resonance occurs at the maximum amplitude, so that the first ground terminal may resonate at the first fixing portion or the first extending portion, and the second ground terminal may resonate at the second fixing portion or the second extending portion, thereby affecting the high-frequency performance of the electrical connector.

Therefore, there is a need to design an electrical connector to solve the above-mentioned technical problems.

Finally, the metal shell 7 is assembled outside the insulating body 1, so that the two folded portions 71 enter the two holding grooves 12, respectively.

In summary, the electrical connector a of the present invention has the following advantages:

(1) the first positioning plate 41 is disposed between the first fixing portion 222 and the second fixing portion 322, and the second positioning plate 42 is disposed between the first extending portion 223 and the second extending portion 323, so that the shielding sheet 4 can shield not only the signal interference between the first fixing portion 222 and the second fixing portion 322, but also the signal interference between the first extending portion 223 and the second extending portion 323 can be shielded by the shielding sheet 4, and further the shielding sheet 4 has a good shielding effect. The shielding plate 4 has the first elastic sheet 43, the second elastic sheet 45, the third elastic sheet 46 and the fourth elastic sheet 48, the first elastic sheet 43 and the third elastic sheet 46 are abutted to the first grounding terminal 22, and the second elastic sheet 45 and the fourth elastic sheet 48 are abutted to the second grounding terminal 32, so that the abutting between the shielding plate 4 and the first grounding terminal 22 and the second grounding terminal 32 is more stable, so that the potentials of the first grounding terminal 22 and the second grounding terminal 32 are equal, and the first grounding terminal 22 and the second grounding terminal 32 have a good grounding effect. Moreover, the first elastic piece 43 is connected to the first positioning plate 41 through the first bending portion 431, the second elastic piece 45 is connected to the first positioning plate 41, the horizontal projection of the second elastic piece 45 is completely dislocated with the horizontal projection of the first bending portion 431, the third elastic piece 46 is connected to the second positioning plate 42 through the second bending portion 461, the fourth elastic piece 48 is connected to the second positioning plate 42, and the horizontal projection of the third elastic piece 46 is completely dislocated with the horizontal projection of the second bending portion 461, so that the second elastic piece 45 and the fourth elastic piece 48 are prevented from being scratched by a bending mold when the first bending portion 431 and the second bending portion 461 are bent.

(2) The second elastic sheet 45 is formed by piercing, bending and extending the first elastic sheet 43 and the first positioning plate 41, so that the second elastic sheet 45 does not need to be additionally arranged at other positions of the shielding sheet 4, and the second elastic sheet 45 can be ensured to have enough length to abut against the second fixing portion 322. The horizontal projection of the second elastic sheet 45 in the front-back direction is located right behind the horizontal projection of the first bent portion 431, so that the second elastic sheet 45 is prevented from being scratched by a bending die when the first bent portion 431 is bent by the bending die.

(3) The fourth elastic piece 48 is formed by piercing, bending and extending the third elastic piece 46 and the second positioning plate 42, so that the fourth elastic piece 48 does not need to be additionally arranged at other positions of the shielding plate 4, and the fourth elastic piece 48 can be ensured to have enough length to abut against the second extending portion 323. The vertical projection of the fourth resilient tab 48 in the up-down direction is located right above the vertical projection of the second bending portion 461, so as to avoid the fourth resilient tab 48 from being scratched by a bending mold when the second bending portion 461 is bent by the bending mold.

(4) Each of the first bent portions 431 has one of the first bent beams 4311 and one of the second bent beams 4312, and the first piercing groove 44 is located between the first bent beam 4311 and the second bent beam 4312 in the left-right direction; each of the second bending portions 461 has one third bending beam 4611 and one fourth bending beam 4612, and the second puncturing groove 47 is located between the third bending beam 4611 and the fourth bending beam 4612 along the left-right direction. Thus, the situation that the first bending portion 431 and the second bending portion 461 are broken when only one bending beam is disposed on the first bending portion 431 and the second bending portion 461 and the width of the bending beam is relatively narrow is avoided, and the situation that the first grounding terminal 22 is bent or deviated when the first bending portion 431 and the second bending portion 461 are only disposed on one bending beam and the width of the bending beam is relatively wide is avoided because the forward force of the first elastic sheet 43 and the third elastic sheet 46 is too large and thus the pushing force of the first elastic sheet 43 against the first fixing portion 222 is too large and the pushing force of the third elastic sheet 46 against the first extending portion 223 is too large.

(5) The abutting position of the first elastic sheet 43 and the first fixing portion 222 is located on one side of the first fixing portion 222 close to the first contact portion 221, and the abutting position of the third elastic sheet 46 and the first extending portion 223 is located on one side of the first extending portion 223 close to the first welding portion 224. Since the first contact portion 221 needs to be abutted against the mating component, and the first welding portion 224 needs to be welded to the circuit board, the signal interference received by the first ground terminal 22 at the first contact portion 221 and the first welding portion 224 is relatively large, so that the abutting position of the first elastic sheet 43 is close to the first contact portion 221, and the abutting position of the third elastic sheet 46 is close to the first welding portion 224, which can better shield the signal interference at the first contact portion 221 and the first welding portion 224, so that the electrical connector a has a good shielding effect.

(6) One end of the first flat plate portion 421 close to the first positioning plate 41 is connected to the first positioning plate 41 and is disposed at an angle with the first positioning plate 41, and the other end of the first flat plate portion 421 away from the first positioning plate 41 is connected to the second flat plate portion 422 and is disposed at an angle with the second flat plate portion 422. So, tearing when fourth shell fragment 48, second linkage segment 482 need not buckle again, has saved fourth shell fragment 48's manufacturing procedure, moreover first flat board portion 421 respectively with second flat board portion 422 reaches first locating plate 41 all is the angle setting, compare in not first locating plate 41 with set up between the second flat board portion 422 first flat board portion 421, but directly with second locating plate 42 directly buckle a fillet from first locating plate 41, saved first locating plate 41 with the shared space of department of buckling between the second locating plate 42 makes second insulator block 6 is in first flat board portion 421 has thicker thickness, has strengthened second insulator block 6 is in the intensity of first flat board portion 421.
