<How to assemble a vertical electrical connector>
A method for assembling the vertical electrical connector 1 according to the embodiment of the present invention will be described in detail below.

  First, the shield member 10 is formed by pressing a metal plate. At this time, the locking piece 13 is formed by punching and bending the metal plate.

  Also, a sub-housing 40a integrally holding the terminal 30 by insert molding and a sub-housing 40b integrally holding the terminal 30 by insert molding are formed. The terminal portion 32 of the terminal 30 held by the sub-housing 40a is formed by being integrally held by the sub-housing 40a and then bent in a direction orthogonal to the longitudinal direction of the terminal 30. The terminal portion 32 of the terminal 30 held by the sub-housing 40b is formed by being integrally held by the sub-housing 40b and then bent in a direction orthogonal to the longitudinal direction of the terminal 30.

  Further, the main housing 20 holding the shielding plate 50 integrally is formed by insert molding.

  After preparing the shield member 10, the sub-housing 40a holding the terminal 30, the sub-housing 40b holding the terminal 30, and the main housing 20 holding the shielding plate 50, the shielding member 50 vertically separates the two. The sub-housing 40a holding the terminal 30 is inserted from one side into one of the holding holes 23 (see FIG. 1). At this time, since the holding hole 23 is vertically divided by the shielding plate 50, the sub-housing 40a can be easily inserted into the holding hole 23 while being positioned. Since the sub-housing 40a and the sub-housing 40b have the same configuration, and the terminal 30 held by the sub-housing 40a and the terminal 30 held by the sub-housing 40b have the same configuration, they are inserted into the holding holes 23. By eliminating the need for sorting the terminal 30 and the sub-housing 40, the workability can be improved and the terminal 30 and the sub-housing 40 can be easily manufactured.

  The sub-housing 40a is inserted into the holding hole 23 with the engaging projection 41 pressed against the inner wall of the holding hole 23 of the main body 21 and the shielding plate 50 elastically deformed.

  The connecting portion 31 of the terminal 30 held integrally with the sub-housing 40a moves forward along the insertion groove 24 while being pressed into the insertion groove 24.

  When the engagement protrusion 41 of the sub-housing 40a reaches the position of the through hole 25 of the main body, the pressure contact state between the engagement protrusion 41 and the inner wall of the holding hole 23 is released and the shielding plate 50 Is returned to the original position by its own elastic force, so that the engagement protrusion 41 is engaged with the inner wall of the through hole 25. The connecting portion 31 is pressed into the insertion groove 24 and held. As a result, the terminal 30 and the sub housing 40a are held by the main housing 20.

  Next, the sub-housing 40b holding the terminal 30 is inserted from the rear into the other of the holding holes 23 divided vertically by the shielding plate 50. At this time, since the holding hole 23 is vertically divided by the shielding plate 50, the sub-housing 40b can be easily inserted into the holding hole 23 while being positioned. Further, when the sub-housing 40a is about to be lowered before the sub-housing 40b is inserted into the holding hole 23, the sub-housing 40a is pressed upward by the urging force of the shielding plate 50. When inserted in the sub housing 23, the sub housing 40a can be kept out of the way. Furthermore, since the sub-housing 40a and the sub-housing 40b have the same configuration, and the terminal 30 held by the sub-housing 40a and the terminal 30 held by the sub-housing 40b have the same configuration, they are inserted into the holding holes 23. By eliminating the need for sorting the terminal 30 and the sub-housing 40, the workability can be improved and the terminal 30 and the sub-housing 40 can be easily manufactured.

  The sub housing 40b is inserted into the holding hole 23 while the engaging protrusion 41 is in pressure contact with the inner wall of the holding hole 23 of the main body 21.

  The connecting portion 31 of the terminal 30 integrally held by the sub-housing 40b moves forward along the insertion groove 24 while being pressed into the insertion groove 24.

  When the engagement protrusion 41 of the sub-housing 40b reaches the position of the through hole 25 of the main body, the pressure contact state between the engagement protrusion 41 and the inner wall of the holding hole 23 is released, and the engagement protrusion 41 41 engages with the inner wall of the through hole 25. The connecting portion 31 is pressed into the insertion groove 24 and held. As a result, the terminal 30 and the sub housing 40b are held by the main housing 20.

  Next, the main housing 20 holding the terminal 30, the sub housing 40a, and the sub housing 40b is inserted into the shield member 10 through the opening 12.

  The main housing 20 is inserted into the shield member 10 with the locking pieces 13 of the shield member 10 elastically deformed outward.

  When the through hole 25 of the main body 21 reaches the position of the locking piece 13 of the shield member 10, the locking piece 13 is engaged with the inner wall of the through hole 25 by the elastic return force of the locking piece 13. Thereby, the main housing 20 is held by the shield member 10.

  Finally, if necessary, the flange member 60 is attached to the shield member 10 to complete the assembly of the electrical connector 1.

  Although the main housing 20 is held by the shield member 10 after the sub housing 40 is held by the main housing 20, the sub housing 40 is held by the main housing 20 after the main housing 20 is held by the shield member 10. May be. Although the sub-housing 40b is inserted into the holding hole 23 after the sub-housing 40a is inserted into the holding hole 23, the sub-housing 40a may be inserted into the holding hole 23 after inserting the sub-housing 40b into the holding hole 23.

<How to assemble a horizontal electrical connector>

The sub-housing 40a holding the terminal 70 is inserted into one of the holding holes 23 from behind. At this time, since the holding hole 23 is vertically divided by the shielding plate 50, the sub-housing 40a can be easily inserted into the holding hole 23 while being positioned.

  The sub-housing 40a is inserted into the holding hole 23 with the engaging projection 41 pressed against the inner wall of the holding hole 23 of the main body 21 and the shielding plate 50 elastically deformed.

  The connecting portion 71 of the terminal 70 integrally held by the sub-housing 40a moves forward along the insertion groove 24 while being pressed into the insertion groove 24.

  When the engagement protrusion 41 of the sub-housing 40a reaches the position of the through hole 25 in the main body, the pressure contact state between the engagement protrusion 41 and the inner wall of the holding hole 23 is released, and the engagement protrusion 41 41 engages with the inner wall of the through hole 25. The connecting portion 71 is pressed into the insertion groove 24 and held. As a result, the terminal 70 and the sub housing 40a are held by the main housing 20.

  Next, the sub-housing 40b holding the terminal 80 is inserted from the rear into the other of the holding holes 23 divided vertically by the shielding plate 50. At this time, since the holding hole 23 is vertically divided by the shielding plate 50, the sub-housing 40b can be easily inserted into the holding hole 23 while being positioned.

  The sub housing 40b is inserted into the holding hole 23 while the engaging protrusion 41 is in pressure contact with the inner wall of the holding hole 23 of the main body 21.

  The connecting portion 81 of the terminal 80 integrally held by the sub-housing 40b moves forward along the insertion groove 24 while being pressed into the insertion groove 24.

  When the engagement protrusion 41 of the sub-housing 40b reaches the position of the through hole 25 of the main body, the pressure contact state between the engagement protrusion 41 and the inner wall of the holding hole 23 is released, and the engagement protrusion 41 41 engages with the inner wall of the through hole 25. The connecting portion 31 is pressed into the insertion groove 24 and held. Thus, the terminal 80 and the sub housing 40b are held by the main housing 20.
