Electric connector, terminal assembly and electronic assembly

The invention provides an electric connector. The first and second slots of the insulating housing are separated by a separation portion. The first and second walls protrude outwardly away from the first slot, respectively, to form first and second accommodating portions. The first accommodating groove and the second accommodating groove respectively extend into the first accommodating part and the second accommodating part from the first slot along the vertical direction. The plurality of first conductive terminals are arranged in the first accommodating groove and the second accommodating groove, so that the matching contact part of the matching end is exposed in the first slot. The middle part of each first conductive terminal is arranged between the corresponding two adjacent arm parts of the plurality of arm parts of the insulation shell and is kept in position relative to the insulation shell. Through at least one of the configurations, the conductive terminals with larger sizes and/or larger intervals
