Description

  The present invention relates to a multiple connector in which two or more connectors are formed side by side in the same casing.

  2. Description of the Related Art Conventionally, a multi-connector of a type in which two or more connectors are formed side by side in the same housing is known in which the entire outer periphery is covered only with a plastic mold. This type requires a mold thickness in order to ensure mechanical strength, and is limited to miniaturization.

Also known is one in which the outer periphery of a plastic housing is covered with a metal shell also serving as a shield case (Patent Document 1). As shown in FIG. 7, the housing 10 is formed by arranging a coaxial connector portion 12 having a coaxial connector insertion hole 14 and a multipolar connector portion 13 having a multipolar connector insertion hole 15 in a flat manner. Is covered with the front cylindrical portion 18 of the shield case 11. For fixing the housing 10 and the shield case 11, a holding groove 16 is formed at the boundary between the coaxial connector portion 12 and the multipolar connector portion 13, and a bent locking edge 17 formed by bending the shield case 11 is press-fitted. It will be. Reference numeral 19 denotes a cover body.
