The insertion hole 421 only needs to receive the receptacle contact 44, and its shape and size are appropriately designed in consideration of connection stability, holding force, strength, workability, and the like.

  The insertion hole 421 is formed with a curved inclined portion 422. The inclined portion 422 extends along the inclined portion 445 of the receptacle contact 44, and is a portion for adjusting backup such as lifting prevention, so that a stable connection can be obtained. The shape and size of the inclined portion 422 is designed as appropriate along the inclined portion 445 of the receptacle contact 44 and considering such a role, connection stability, workability, and the like.

  The housing 42 is pressed on both sides in the longitudinal pitch direction and on both sides in the width direction so as to press the second fixing tool 46 and simultaneously escape the connecting portion 261 of the first fixing tool 26 when the second fixing tool 46 is integrally formed. Indentation 424 is provided. The shape and size of the recess 424 are appropriately designed in consideration of such a role, a low profile, strength, workability, and the like.

  Finally, the second fixture 46 will be described with reference to FIG. The second fixture 46 is made of metal and is manufactured by a known press working. The material of the second fixture 46 is required to be springy or moldable, and examples thereof include beryllium copper and phosphor bronze.

  The second fixture 46 includes at least a connection portion 462 connected to the substrate and a second contact means 463 that contacts the first contact means 263 of the first fixture 26. Further, in this embodiment, a main body portion 461 and a protruding portion 464 that protrudes at a substantially right angle from the main body portion 461 are provided. In this embodiment, the connecting portion 462 is a surface mounting (SMT) type in consideration of mounting density and the like, but may be a dip type. The connecting portions 462 are provided on both sides in the width direction.

  The second fixture 46 is held in the housing 42 by integral molding. The main body portion 461 and the protruding portion 463 are portions that reinforce the strength of the housing 42. The shape and size of the main body portion 461 and the protruding portion 463 may be designed as appropriate in consideration of strength, workability, and the like as long as strength can be reinforced.

  The second contact means 463 is a part that contacts the first fixture 26 of the plug connector 20 and may have any shape and size as long as it can be contacted. However, the connection stability, elasticity, workability, strength, etc. Design accordingly. In this embodiment, the main body 261 is bent so as to have elasticity in a substantially S shape. The second contact means 463 of the receptacle connector 40 is used as a power source by contacting the first contact means 26 of the plug connector 20.

  In this embodiment, the base portion of the second contact means 463 of the main body 461 may be provided with a recess 465 for extending the elastic length (increasing the elasticity). The shape and size of the recess 465 is designed in consideration of connection stability, elasticity, strength, workability, and the like.

  Hereinafter, another second fixture 26 will be described. The purpose and material are the same as those described above. Only the differences will be described.

Based on FIG. 8, another second fixture 46 will be described.
The second contact means 463 of the second fixture is a substantially I-shaped second contact piece having elasticity. Further, a projecting piece 466 that is bent in parallel with the main body 461 from the main body 461 of the second fixture 46 is provided. The protruding piece 466 is provided to give more strength when the second fixture 46 is integrally formed with the housing 42. In this embodiment, the surface of the protruding piece 466 is separated from the housing 42. Although it is exposed, it may be completely embedded in the housing 42 without being exposed.

Based on FIG. 9, another second fixture 46 will be described. The material is the same as above.
The second contact means 463 of the second fixing tool is a second contact piece having elasticity that is bent into a substantially J shape. The second contact piece is bent from the substrate side to the fitting side.

Based on FIG. 10, another second fixture 46 will be described. The material is the same as above.
The second contact means 463 of the second fixing tool is a second contact piece having elasticity that is bent into a substantially J shape. The second contact piece is bent from the fitting side to the substrate side.

Based on FIG. 11, another second fixture 46 will be described. The material is the same as above.
The second contact means 463 of the second fixture is a second contact piece having elasticity that is bent into a substantially L shape. The second contact piece is bent from the fitting side to the substrate side.

  The present invention is utilized for electrical connectors used in communication devices such as portable terminals and audio devices, electrical devices and electronic devices, and in particular, while achieving miniaturization (space saving of the board occupied area) and low profile, The present invention relates to a structure that can maintain strength and connection stability and obtain a stable fitting.
