  • Patent number: 8500478
    Abstract: An electrical connector (100) comprises includes an insulative housing (1) having a receiving space (14), a plurality of terminals (21) retained in the insulative housing (1), a metal retaining portion (3) assembled on the insulative housing (1). The insulative housing (1) comprises includes a pair of block portions (111, 111?) extending toward opposite direction directions with each other; and each of the blocking portions has a resisting face (1110). The metal retaining metal (3) includes a reinforced portion (310) arranged behind the blocking portion (111, 111?) and attached to the resisting face (1110) of the blocking portion (111, 111?). Therefore, it can prevent the blocking portion (111, 111?) of the housing (1) from breaking off during an unexpected situation.

  • Patent number: 8403703
    Abstract: An electrical connector includes an insulative housing having a base portion defining a receiving cavity therein and a mating portion unitarily formed with the base portion and protruding outwardly from a front face of the base portion so as to define an insertion opening in communication with the receiving cavity. A plurality of terminals are received in the receiving cavity, each of which has a contacting portion extending rearwardly and upwardly from a position adjacent to the insertion opening. A rear cover is assembled on a rear section of the base portion and severs as a rear wall of the base portion. The insulative housing is formed by a double-colored-injection method and the mating portion and the base portion are configured as different colors. The double-colored-injection method can save an assembling process for the electrical connector, which is helpful for reducing the manufacturing cost.
