Description

  The present invention relates to a connector formed by fitting a male connector and a female connector.

  In a connector for fitting a male connector and a female connector, it is necessary to suppress backlash in the vertical direction and the horizontal direction. Patent Literature 1 and Patent Literature 2 describe conventional connectors having a function of suppressing backlash.

  FIG. 8 shows an outline of these conventional connectors 100, which are formed by a female connector 110 and a male connector (not shown). The female connector 110 includes a connector main body 130 having a terminal accommodating chamber (not shown), and a cylindrical fitting hood 140 that is provided around the connector main body 130 with a space therebetween and surrounds the connector main body 130. . Between the outer periphery of the connector main body 130 and the fitting hood 140, there is an insertion space 120 into which the outer hood of the mating male connector is inserted.

  In the connector 100, in order to suppress the backlash in the vertical direction, back and forth portions 200 including ribs 180 and grooves 190 are provided on the left and right sides of the fitting hood 140. A rib (not shown) of the outer hood of the male connector is formed so as to protrude from the left and right side surfaces, and a groove 190 into which the rib is fitted is formed at a corresponding position on the inner surface of the fitting hood 140. These ribs and grooves 190 are formed long along the fitting direction of the outer hood of the mating male connector and the fitting hood 140 (the through-plane penetration direction). By fitting the ribs and the grooves 190, the lateral play of the female connector 110 and the male connector is suppressed. In FIG. 8, a portion indicated by a broken line G is a place where the backlash suppressing unit 200 in the left-right direction is provided.

The backlash suppressing portion that suppresses the backlash in the vertical direction is provided above and below the fitting hood 140. The vertical play suppressing portion is formed by ribs and grooves extending in the fitting direction of the fitting hood 140 in the same manner as the horizontal play suppressing portion 200. For example, the ribs are the upper and lower surfaces of the outer hood of the mating male connector. In addition, grooves are provided at corresponding positions on the upper and lower inner surfaces of the fitting hood 140. In FIG. 8, the portion indicated by the broken line H is a place where the vertical backlash suppressing portion is provided, and is provided at a total of four places, two places at the top and bottom.
