Abstract

A connector includes contacts and an insulator. Each contact includes a contact portion, a first fixed portion, an elastic portion substantially in the form of a crank, a second fixed portion and a connection portion. The insulator includes a fixation block to which the second fixed portions are fixed, and a movable housing to which the first fixed portions are fixed. The movable housing is fixed only to the contacts and held by the elastic portions in a floating condition away from the bottom surface of the fixation block. The fixation block has a wall for preventing short circuit when the connector is being mounted on a substrate. A floating amount of more than 0.7 mm can be achieved with a simple construction without causing short circuit with a substrate when the connector is being fitted with a mating connector and without causing any failed connection.

Claims

1. A connector to be detachably fitted with a mating connector, including a plurality of contacts and an insulator for arranging and holding said contacts therein,

wherein said contacts each comprise a contact portion at one end adapted to contact said mating connector;

a connection portion at the other end to be connected to a substrate; and

between said contact portion and said connection portion, a first fixed portion, a second fixed portion and an elastic portion having elasticity are provided; and

said these portions being arranged in the order of the contact portion, the first fixed portion, the elastic portion, the second fixed portion and the connection portion, and said elastic portion being substantially in the form of a crank, and

wherein said insulator comprises a fixation block to which said second fixed portions of said contacts are fixed and a floating movable housing to which said first fixed portions of said contacts are fixed, and said movable housing is fixed only to said contacts and held by said elastic portions of said contacts in a floating manner away from a bottom surface of said fixation block,

wherein said movable housing is provided at each of its longitudinal ends with a protruding portion, and arranged on said fixation block are fixing tabs which are substantially U-shaped and to be connected to the substrate so tat said fixing tabs engage said protruding portions of the movable housing to restrict movement of the movable housing from moving away from said fixation block when the mating connector is disengaged.

2. The connector as set forth in claim 1, wherein said fixation block has a substantially U-shaped cross-section, and said movable housing has a substantially inverted T-shaped cross-section.

3. The connector as set forth in claim 2, wherein said elastic portion of each of said contacts is 1.0 to 5.0 mm in length, thereby increasing a floating amount of the movable housing.

4. The connector as set forth in claim 1, wherein said elastic portion of each of said contacts is 1.0 to 5.0 mm in length, thereby increasing a floating amount of the movable housing.

5. A connector to be detachably fitted with a mating connector, including a plurality of contacts and an insulator for arranging and holding said contacts therein,

wherein said contacts each comprise a contact portion at one end adapted to contact said mating connector;

a connection portion at the other end to be connected to a substrate; and

between said contact portion and said connection portion, a first fixed portion, a second fixed portion and an elastic portion having elasticity are provided; and

said these portions being arranged in the order of the contact portion, the first fixed portion, the elastic portion, the second fixed portion and the connection portion, and said elastic portion being substantially in the form of a crank,

wherein said insulator comprises a fixation block to which said second fixed portions of said contacts are fixed and a floating movable housing to which said first fixed portions of said contacts are fixed, and said movable housing is fixed only to said contacts and held by said elastic portions of said contacts in a floating manner away from a bottom surface of said fixation block,

wherein said fixation block has a substantially U-shaped cross-section, and said movable housing has a substantially inverted T-shaped cross-section, and

wherein said movable housing is provided at each of its longitudinal ends with a protruding portion, and arranged on said fixation block are fixing tabs which are substantially U-shaped and to be connected to the substrate so that said fixing tabs engage said protruding portions of the movable housing to restrict movement of the movable housing from moving away from said fixation block when the mating connector is disengaged.

6. The connector as set forth in claim 5, wherein said elastic portion of each of said contacts is 1.0 to 5.0 mm in length, thereby increasing a floating amount of the movable housing.
