That is, the front end portions of the extending portions 462 and 463 are formed in a tapered shape so that the width becomes narrower toward the fixed portion 44 side in the direction 91. Furthermore, in other words, when the contact 4 is inserted into the housing 5 (see FIG. 1), the portion of each of the extending portions 462 and 463 that is first inserted into the internal space 51 of the housing 5 is narrower. It is formed in a taper shape. The width is the length from the base 461 to the tips of the extending portions 462 and 463 in the direction 93. Thereby, when the contact 4 is inserted into the housing 5, the extended portions 462 and 463 can be hardly caught by the housing 5. As a result, the contact 4 can be easily inserted into the housing 5 even when the total length of the contact 4 is increased by the protrusion 46.

  Next, the housing 5 will be described with reference to FIGS.

  As shown in FIG. 5, the housing 5 is made of a synthetic resin molded product having insulating properties, and has a plurality of internal spaces 51 into which the contacts 4 are inserted.

When the contact 4 is inserted to a predetermined position, as shown in FIG. 6, the contact 45 formed by cutting and raising a part of the contact 4 is engaged with the hole 52 of the housing 5. It is held in a state where it is arranged in the space 51. In a state where the contact 4 is disposed in the internal space 51, the first contact 421 and the second contact 422 included in the contact 4 are disposed to face each other in the direction 93. Thereby, when the plug connector 2 is inserted into the receptacle connector 3, the first contact 421 and the second contact 422 come into contact with the corresponding post 31. As a result, the post 31 is electrically connected to the core wire 61 of the electric wire 6.

  In such a plug connector 2, the base 461 contacts the upper surface 513 (see FIG. 9) of the internal space 51 at the protrusion 46 of the contact 4. The pair of extending portions 462 and 463 engage with the concave portions 531 and 532 of the housing 5, and the tips of the pair of extending portions 462 and 463 come into contact with the inner surfaces (side surfaces 511 and 512) of the internal space 51. . Thereby, even if the electric wire 6 vibrates in the direction 92 or in the direction 93, the moving amount of the contact 4 in the internal space 51 of the housing 5 is reduced. As a result, the position shift of the contact portion 42 of the contact 4 can be reduced.

  Next, the receptacle connector 3 will be described with reference to FIGS.

  As shown in FIG. 6, the receptacle connector 3 includes a plurality of posts (conductive members) 31, a housing 32 that supports the plurality of posts 31, and a holding member 35 that holds the strength and adhesive strength of the housing 32.

The protrusion 46 reduces the amount of movement of the contact 4 in the internal space 51 of the housing 5 at least in a predetermined direction (directions 92 and 93) orthogonal to the longitudinal direction. Thereby, in the plug connector 2 according to the present embodiment, the displacement of the contact portion 42 of the contact 4 in the internal space 51 of the housing 5 can be reduced, so that the wear of the contact portion 42 can be reduced. . In particular, when mounted on an automobile, there is a lot of vibration, but in the connector device 1 according to this embodiment, the wear of the contact portion 42 can be reduced.

  Further, in the plug connector 2 according to the present embodiment, since the protruding portion 46 is provided independently of the fixed portion 44, a design (shape / dimension setting) specialized for vibration suppression is applied to the protruding portion 46. It can be carried out.

  Furthermore, in the plug connector 2 according to the present embodiment, the extending portions 462 and 463 are formed in a tapered shape. Thereby, in the plug connector 2 according to the present embodiment, the extended portions 462 and 463 can be hardly caught by the housing 5 when the contact 4 is inserted into the housing 5. As a result, even if the total length of the contact 4 in the longitudinal direction (direction 91) is increased by the protrusion 46, the contact 4 can be easily inserted into the housing 5. In particular, even if the clearance is reduced, the contact 4 can be easily inserted into the housing 5.

  In the plug connector 2 according to the present embodiment, the base portion 461 of the protruding portion 46 is provided so as to protrude from the central portion of the fixing portion 44. Thereby, in the plug connector 2 according to the present embodiment, even if both end portions of the fixing portion 44 are bent in order for the fixing portion 44 to fix the covering portion 62 of the electric wire 6, the position of the protruding portion 46 does not change.
