According to the utility model, the buckle plate 322 which is offset towards the direction of the accommodating cavity 31 is arranged on the shielding shell 3, and the buckle hole 3221 is arranged on the buckle plate 322, so that the position of the buckle hole 3221 at the buckle plate 322 is offset towards the direction of the accommodating cavity 31, and the height between the buckle hole 3221 and the insulating body 1 is reduced at the buckle plate 322, so that when the butt joint connector 200 is inserted, the clamping amount of the butt joint connector 200 and the buckle hole 3221 is increased, and the connection between the electric connector 100 and the butt joint connector 200 is more stable and is not easy to trip. Meanwhile, the distance between the base 321 and the insulating body 1 is not changed, so that the interference between the electric connector 100 and the mating connector 200 is less affected, and an operator can easily operate to separate the two from each other.

The electric connector and the electric connector assembly have the following beneficial effects:

1) The buckle 322 is offset in the first direction from the base 321 toward the accommodating cavity 31, so that the buckle hole 3221 provided on the buckle 322 is also offset in the direction of the accommodating cavity 31 from the base 321, and in the position of the buckle 322, the height of the accommodating cavity 31 is reduced, so as to increase the fastening strength between the mating connector 200 and the electrical connector 100, but the height of the accommodating cavity 31 is unchanged at the base 321, so that the interference influence on the electrical connector 100 and the mating connector 200 is small, and an operator can easily operate to separate the two from each other.

2) The first dimension D1 is greater than the second dimension D2, so that the area of the buckle 322 is smaller, and when the protrusion 62 is inserted, the interference between the buckle 322 and the protrusion 62 is less affected, so that the electrical connector 100 and the mating connector 200 can be easily tripped.

3) The third dimension D3 is smaller than or equal to the second dimension D2, i.e. the structural strength of the buckle 322 is not affected when the buckle hole 3221 is punched on the buckle 322.

4) The fourth dimension D4 is greater than or equal to the second dimension D2, so that the structural strength of the buckle plate 322 and the base plate 321 can be ensured when the buckle plate 322 and the buckle hole 3221 are formed under the condition that the punching strength is enough and the material is not turned over.

5) The buckle plate 322 is offset from the base plate 321 by 0.10mm towards the plugging cavity Q

0.13Mm, in this interval, the structural strength of buckle 322 is stronger, and buckle intensity is stronger, is difficult for the dropout, is unlikely to block again and dies, easily trips under operator's operation.

6) Compared with the shielding shell 3 made of plastic, the shielding shell 3 made of metal plates by stamping is not easy to damage, and external signals can be shielded; in addition, the base plate 321 is provided with the reinforcing ribs 3212, so as to increase the structural strength of the base plate 321, so that the base plate 321 is not easy to deform, the suction portion 3211 is provided on the base plate 321, and the suction portion 3211 is located between the reinforcing ribs 3212 in the second direction, so that the arrangement can ensure the balance stability of the electrical connector 100 when the electrical connector 100 is sucked by a machine.

7) In the first direction, opposite edges of the buckle 322 in the second direction are defined between opposite edges of the groove 121 in the second direction, and the groove 121 is configured to receive the reinforcement portion 624 of the mating connector 200, so that the height of the plugging cavity Q can be prevented from being increased, and the mating of the mating connector 200 in the mating direction can be guided.

8) Since the length of the middle portion 23 of the first terminal 2a is longer than the length of the middle portion 23 of the second terminal 2b, the first grounding member 4 abuts against the first extension 231 and the second extension 232 of each of the grounding terminals G in a row of the first terminals 2a, so as to improve resonance of the first terminal 2a and shift the resonance point generated by the first terminal 2a to a higher frequency.

9) The first plate 41 is exposed to the first insulating block 1b on a side close to the abutting surface 10 in the abutting direction, and the second plate 42 is exposed to the first insulating block 1b on a side facing away from the spacer 32 in the first direction, so that the first terminal 2a and the first grounding member 4 are positioned when the first insulating block 1 is injection-molded on the first terminal 2a and the first grounding member 4.

10 The width of the buckle 322 in the second direction is adapted to the width of the elastic portion 81, so that only the amount of interference between the buckle 322 and the elastic portion 81 is increased, without affecting the amount of interference between the base 321 and the protruding portion 62.

The above detailed description is merely illustrative of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model, so that all equivalent technical changes that can be made by the present specification and illustrations are included in the scope of the utility model.
