As shown in fig. 5 and 6, the two elastic members 4 are separately disposed corresponding to the upper row of terminals 2 and the lower row of terminals 2 and are located in the through grooves 13, that is, the plurality of guiding parts 21 are respectively arranged at two sides of the receiving cavity 11, the elastic member 4 adjacent to the upper row of terminals 2 abuts against the corresponding guiding part 21 downwards, and the elastic member 4 adjacent to the lower row of terminals 2 abuts against the corresponding guiding part 21 upwards. The elastic element 4 is a one-piece type, and the elastic element 4 is disposed on one row of the connecting portions 21, so as to prevent the elastic element 4 from not being able to contact with each row of the connecting portions 21 completely, which causes uneven stress on each row of the connecting portions 21, and causes poor contact between the connecting portions 21 and the conductive elements 62.
As shown in fig. 3 and 8, the elastic member 4 has a base 41, a pressing portion 42 extending from the base 41 to be away from the receiving cavity 11, and an abutting portion 43 extending from the base 41 to be close to the receiving cavity 11.

As shown in fig. 5 and 8, a shielding shell 5 is disposed outside the insulating body 1, the shielding shell 5 and the insulating body 1 are configured to be located in the accommodating cavity 71 together, the shielding shell 5 is provided with a through groove 51 corresponding to the through groove 13, the through groove 51 is communicated with the through groove 13, the length of the through groove 51 is smaller than the length of the through groove 13, the press-bonding part 42 is located in the through groove 51, the inner wall of the shielding shell 5 stops the displacement of the base 41 in the direction away from the accommodating cavity 11, and the first contact part 421 protrudes out of the outer surface of the corresponding shielding shell 5, so that when the inserting part 12 enters the accommodating cavity 71, the first contact part 421 abuts against the inner wall of the accommodating cavity 71.

The abutting portion 61 is tapered toward one end of the accommodating cavity 11, and when the inserting portion 12 is inserted into the accommodating cavity 71, the abutting portion 61 plays a role of guiding the conductive element 62 to enter the accommodating cavity 11.
As shown in fig. 6, 7 and 8, after the inserting portion 12 is inserted into the accommodating cavity 71, the frame portion 73 is disposed outside the inserting portion 12, the elastic member 4 is disposed between the inner wall of the covering shell 7 and the guiding portion 21, the inner wall of the covering shell 7 abuts against the first contact portion 421 and the second contact portion 431 abuts against the guiding portion 21, the first contact portion 421 abuts against the inner wall of the accommodating cavity 71, the second contact portion 431 abuts against the guiding portion 21, the elastic member 4 provides a positive abutting force of the guiding portion 21 towards the conductive element 62, that is, while the inserting portion 12 is inserted into the accommodating cavity 71, the inner wall of the accommodating cavity 71 abuts against the guiding portion 21 by the elastic member 4, so that the guiding portion 21 abuts against the conductive element 62 and the guiding portion 21 and the conductive element 62 are in tight contact, the situation of poor contact caused by insufficient contact force between the terminal 2 and the conductive element 62 is avoided, and the terminal 2 and the conductive element 62 are in good contact compared with the situation that no elastic member 4 provides positive abutting force.

As shown in fig. 3 and 8, the terminals 2 at the upper row and the terminals 2 at the lower row are respectively formed by injection molding with a base 24, and the terminals 2 at the two rows respectively have a plurality of signal terminals 22 and a plurality of ground terminals 23, and the signal terminals 22 are connected to a tape 25, and the ground terminals 23 are disconnected from the tape 25.

The width of the crimping portion 42 is larger than that of the crimping portion 42 of the first embodiment, and therefore, the first contact portion 421 is better contacted with the inner wall of the covering case 7 to prevent the elastic member 4 from escaping from the accommodating cavity 71. After the inserting portion 12 enters the accommodating cavity 71, since the side of the elastic element 4 close to the conductive element 62 is provided with an inclined surface 44, the inclined surface 44 plays a role of guiding the elastic element 4 to enter the accommodating cavity 11, the elastic element 4 abuts against the guiding portion 21 so that the guiding portion 21 contacts the second contact portion 431, and each of the isolating portions 14 is located between two of the abutting portions 43.

(2) The lead portion 21 has a flat plate shape, and the second contact portion 431 abuts against the lead portion 21 so that the lead portion 21 is horizontally in contact with the conductive member 62. The elastic member 4 provides a positive abutting force of the conductive connection portion 21 toward the conductive element 62, the conductive connection portion 21 and the conductive element 62 are in horizontal surface-to-surface contact, and compared with the conductive connection portion 21 tilted from the conductive element 62, the flat conductive connection portion 21 has no antenna branch, so that under the resistance of the elastic member 4, the electrical contact between the flat conductive connection portion 21 and the conductive element 62 has no stake effect, and the interference of the electrical connection between the terminal 2 and the conductive element 62 is reduced.
