The body has a mating surface and a mating slot extending through the mating surface, the slot being configured to receive the mating module. The module includes a plurality of signal terminals, a plurality of ground terminals, and a grounding tab. Each signal terminal includes a base and a resilient arm extending from the base, the resilient arm having a contact portion. Each ground terminal includes an extension and a grounding spring arm extending from the extension, the grounding spring arm having an abutment portion. The contact portion and the abutment portion are configured to contact the mating module to achieve an electrical connection.

[0003] The grounding plate has a first mating part, a second mating part, a first connecting part connecting the first mating part and the second mating part, a first abutting spring arm, and a second abutting spring arm.
