  By the way, in the said conventional connector apparatus, although the backlash between the 1st connector housing 110 and the 2nd connector housing 120 can be prevented, it prevents that the vibration added from the outside acts on the contact part of internal terminals. Is expected to be difficult. In addition, if the part where the backlash regulation occurs due to secular change, etc., the backlash control function weakens, the vibration transmitted to the inside becomes larger, and the sliding wear (contact wear) of the contact part between the terminals increases. It is expected to grow. Furthermore, since it is necessary to prepare the wedge-shaped backlash regulating member 130 separately from the first and second connector housings 110 and 120, there are problems in that the parts cost is increased and the assembling workability is deteriorated.

  In consideration of the above circumstances, the present invention can prevent sliding abrasion (contact wear) of the contact portions between the terminals by minimizing vibration transmitted from the outside to the contact portions of the terminals without increasing the number of parts. An object of the present invention is to provide a connector device.

  The connector device is accommodated in the female connector housing (first connector housing) 10 and the male connector housing (second connector housing) 30 which are fitted to each other, and the connector housings 10, 30. A male terminal and a female terminal (both not shown) are electrically connected to each other when 30 is fitted.

  The female connector housing 10 and the male connector housing 30 are respectively located in the outer peripheral portion and fitted into the tubular hood portions 11, 31, and the annular spaces 12, 32 at the center of the inner space of each hood portion 11, 31. Connector body parts 13 and 33 that respectively accommodate connection terminals (not shown) that are positioned via the connector and are electrically connected to each other in a non-contact manner with both hood parts 11 and 31; A plurality of ribs 18 and 38 for integrally connecting the connector main body portions 13 and 33 to the hood portions 11 and 31 via the annular spaces 12 and 32 are integrally provided at the rear ends in the direction. It is composed of a resin molded product.

  The hood parts 11 and 31 and the connector main body parts 13 and 33 of the female connector housing 10 and the male connector housing 30 are respectively formed in a substantially square shape (rectangular shape) concentric when viewed from the front in the connector fitting direction. At the front end of the connector main body 13 of the female connector housing 10, a rectangular tube wall 14 is provided in which the front end of the connector main body 33 of the male connector housing 30 is fitted into the fitting hole 15.

  Here, the male terminal (not shown) accommodated in the female connector housing 10 is fixed at the base end to the terminal accommodating hole 16 provided in the connector main body 13, so that the distal end is from the bottom wall of the fitting hole 15. Protruding forward. A female terminal (not shown) housed in the male connector housing 30 is housed and fixed in the terminal housing chamber 36 of the connector main body 33.

  The ribs 18 and 38 for connecting the connector main body portions 13 and 33 to the hood portions 11 and 31 are arranged at intervals in the circumferential direction of the connector main body portions 13 and 33, respectively. The ribs 18 and the ribs 38 on the second connector housing 30 side are arranged so that their positions are shifted so that the positions are reversed when viewed from the front in the connector fitting direction. Each of the ribs 18 and 38 is provided for each of the four opposite sides of the connector main body portions 13 and 33 and the hood portions 11 and 31 having a substantially square shape when viewed from the front. The ribs 18 and 38 that are in a positional relationship facing each other are arranged with their positions shifted to the maximum on the opposite side on each side, and in the circumferential direction of the connector main body portions 13 and 33 between the adjacent ribs 18 and 38. The interval is set to be the maximum.

  When the female connector housing 10 and the male connector housing 30 thus configured are fitted as shown in FIGS. 2 and 3, the inner periphery of the hood portion 11 of the female connector housing 10 is shown in FIGS. The outer periphery of the hood portion 31 of the male connector housing 30 is fitted to the outer periphery. At the same time, the outer periphery of the connector main body 33 of the male connector housing 30 is fitted into the inner periphery of the fitting hole 15 at the front end of the connector main body 13 of the female connector housing 10.
