<Assembly method of vertical type electrical connector>
A method of 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 the metal plate and bending it.

  Further, a sub housing 40a that integrally holds the terminal 30 by insert molding and a sub housing 40b that integrally holds the terminal 30 by insert molding are formed. The terminal portion 32 of the terminal 30 held by the sub-housing 40 a is formed by being held integrally with the sub-housing 40 a and then bent in a direction perpendicular 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 held integrally with the sub-housing 40b and then bent in a direction perpendicular to the longitudinal direction of the terminal 30.

  Furthermore, the main housing 20 that integrally holds the shielding plate 50 is formed by insert molding.

  After preparing the shield member 10, the sub-housing 40 a holding the terminal 30, the sub-housing 40 b holding the terminal 30, and the main housing 20 holding the shielding plate 50, the shielding member 50 is divided vertically. The sub-housing 40a holding the terminal 30 is inserted from the rear 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 while being positioned in the holding hole 23. 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, so that they are inserted into the holding holes 23. By eliminating the need to select the terminal 30 and the sub-housing 40, workability can be improved and manufacturing can be easily performed.

  The sub-housing 40a is inserted into the holding hole 23 in a state where the engaging protrusion 41 is in pressure contact with the inner wall of the holding hole 23 of the main body 21 and the shielding plate 50 is elastically deformed.

  The connection portion 31 of the terminal 30 held integrally with the sub-housing 40a moves forward along the insertion groove 24 while being press-fitted 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 restored to its original position by its own elastic force, whereby the engaging protrusion 41 is engaged with the inner wall of the through hole 25. The connecting portion 31 is press-fitted and held in the insertion groove 24. As a result, the terminal 30 and the sub-housing 40a are held in the main housing 20.

  Next, the sub-housing 40b holding the terminal 30 is inserted into the other of the holding holes 23 divided vertically by the shielding plate 50 from the rear. At this time, since the holding hole 23 is vertically divided by the shielding plate 50, the sub-housing 40b can be easily inserted while being positioned in the holding hole 23. 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, so that the sub housing 40b is held in the holding hole. It is possible to prevent the sub-housing 40a from getting in the way when inserted into the housing 23. Further, 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, so that they are inserted into the holding holes 23. By eliminating the need to select the terminal 30 and the sub-housing 40, workability can be improved and manufacturing can be easily performed.

  The sub-housing 40 b 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 connection portion 31 of the terminal 30 held integrally with the sub-housing 40 b moves forward along the insertion groove 24 while being press-fitted 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 engages with the inner wall of the through hole 25. The connecting portion 31 is press-fitted and held in the insertion groove 24. As a result, the terminal 30 and the sub-housing 40b are held in the main housing 20.

  Next, the main housing 20 holding the terminal 30, the sub-housing 40 a and the sub-housing 40 b 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. Thus, the main housing 20 is held by the shield member 10.

  Finally, the flange member 60 is attached to the shield member 10 as necessary, and the assembly of the electrical connector 1 is completed.

  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. You may let them. Further, 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 the sub housing 40b is inserted into the holding hole 23.

<Assembling method of horizontal type electrical connector>

  The connection portion 71 of the terminal 70 held integrally with the sub-housing 40a moves forward along the insertion groove 24 while being press-fitted 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 engagement protrusion 41 engages with the inner wall of the through hole 25. Further, the connecting portion 71 is press-fitted and held in the insertion groove 24. As a result, the terminal 70 and the sub-housing 40a are held in the main housing 20.

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

  The sub-housing 40 b 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 connection portion 81 of the terminal 80 held integrally with the sub-housing 40 b moves forward along the insertion groove 24 while being press-fitted 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 engages with the inner wall of the through hole 25. The connecting portion 31 is press-fitted and held in the insertion groove 24. As a result, the terminal 80 and the sub-housing 40b are held in the main housing 20.
