As illustrated in FIG. 3, the male connector 47 is attached to the female connector 43 in a direction substantially in parallel with the mounting face 41.
As illustrated in drawings, the X axis, the Y axis, and the Z axis are defined in the specification. The X, Y, and Z axes are orthogonal to each other. The X axis is along an edge 37a of the substrate 37. The edge 37a of the substrate 37 faces the lower end portion 12a of the display portion 12. The Y axis is along a direction in which the male connector 47 is connected to the female connector 43. The Z axis is along the thickness of the substrate 37.
The female connector 43 comprises a first casing 51, a plurality of leads 52, and a pair of stoppers 53. The leads 52 are an example of a conducting portion, the leads 52 can also be referred to as terminals or a connecting portion, for example. The stoppers 53 can also be referred to as a locking portion or a engage portion, for example.
The first casing 51 is formed in an substantially quadrangular box shape. A first end portion 51a of the first casing 51 is along the X axis and faces the edge 37a of the substrate 37. The first end portion 51a of the first casing 51 is provided with an insertion inlet. The male connector 47 is inserted into the insertion inlet.
The first casing 51 is made of metal, for example. The first casing 51 is electrically connected to a ground pattern provided to the substrate 37. The first casing 51 may be formed of another material such as a resin.
The leads 52 extend from a second end portion 51b of the first casing 51 in a direction along the Y axis respectively. The second end portion 51b is opposite the first end portion 51a. The leads 52 are electrically connected to lands provided on the mounting face 41 with solder, for example. As a result of soldering the leads 52 to the lands, the female connector 43 is fixed to the substrate 37.
Each of the stoppers 53 is provided in the first casing 51. The stoppers 53 protrude from a first side portion 51c and a second side portion 51d of the first casing 51 respectively. The first side portion 51c and the second side portion 51d extend along the Y axis. The second side portion 51d is opposite the first side portion 51c.

The harness 49 extends from a second end portion 56b of the second casing 56 in a direction approximately along the Y axis. The second end portion 56b is opposite the first end portion 56a. A surface 49a of the harness 49 substantially continues to an upper face 56c of the second casing 56. Furthermore, the upper face 56c of the second casing 56 substantially continues to an upper face 51e of the first casing 51 of the female connector 43. Thus, the upper face 51e of the first casing 51, the upper face 56c of the second casing 56, and the surface 49 of the harness 49 form a flat face. The surface 49a of the harness 49, the upper face 51e of the first casing 51, and the upper face 56c of the second casing 56 face a side opposite the side facing the mounting face 41.
A locking lever 57 is provided to the male connector 47. The locking lever 57 is an example of the engage portion, the locking lever 57 can also be referred to as a lever, a moving portion, a locking portion, an engaging portion, or a fixing portion, for example. The engage portion is not limited to the locking lever 57, the engage portion may be another component such as a pin, for example.
The locking lever 57 is formed of a bended metallic bar, for example. The locking lever 57 may be formed of another material. The locking lever 57 comprises a first portion 57a, a second portion 57b, and a third portion 57c. The first portion 57a, the second portion 57b, and the third portion 57c are examples of a engage section.
In the state illustrated in FIG. 3, the first portion 57a and the second portion 57b extend along the Y axis. The first portion 57a thus extends in parallel with the second portion 57b. The third portion 57c extends along the X axis. The third portion 57c thus extends in a direction intersecting with the first portion 57a and the second portion 57b. 
One end of the first portion 57a of the locking lever 57 is attached to a first side portion 56d of the second casing 56. One end of the second portion 57b of the locking lever 57 is attached to a second side portion 56e of the second casing 56. The second side portion 56e is opposite the first side portion 56d. The first side portion 56d and the second side portion 56e extend along the Y axis.
The third portion 57c of the locking lever 57 connects the other end of the first portion 57a and the other end of the second portion 57b. In other words, the first portion 57a and the second portion 57b extend from the respective ends of the third portion 57c. In this way, the locking lever 57 is formed in an substantially U-like shape. The locking lever 57 may be formed in another shape.
FIG. 4 is a cross-sectional view illustrating a portion of the display module 32 in a state where the locking lever 57 is at a first position P1. FIG. 5 is a cross-sectional view illustrating a portion of the display module 32 in a state where the locking lever 57 is at a second position P2. In FIG. 5, the locking lever 57 at the first position P1 is indicated with the chain double-dashed line.
The locking lever 57 can be rotated with respect to the male connector 47. The locking lever 57 is configured to move between the first position P1 and the second position P2 by being rotated.
As illustrated in FIG. 4, when the locking lever 57 is at the first position P1, the first portion 57a and the second portion 57b of the locking lever 57 catch the respective stoppers 53 of the female connector 43. In addition, the second end portion 51b of the first casing 51 faces the third portion 57c of the locking lever 57. Then, the mounting face 41 of the substrate 37 also faces the third portion 57c of the locking lever 57.
The locking lever 57 fixes the male connector 47 in such a state that the male connector 47 is connected to the female connector 43 by engaging the female connector 43. In other words, the locking lever 57 locks the male connector 47 to the female connector 43. The locking lever 57 prevents the male connector 47 from separating from the female connector 43 with the third portion 57c engaging the second end portion 51b of the first casing 51, for example.
As illustrated in FIG. 5, when the locking lever 57 is at the second position P2, the locking lever 57 disengages the female connector 43. Thus, the male connector 47 can be removed from the female connector 43 when the locking lever 57 is at the second position P2. When the locking lever 57 moves from the first position p1 to the second position P2, the first portion 57a and the second portion 57b of the locking lever 57 pass over the stoppers 53. In other words, the stoppers 53 are between the first position P1 and the second position P2.
As illustrated in FIG. 4, a fixing portion 60 is attached to the female connector 43 and the male connector 47. The fixing portion 60 can also be referred to as an attaching portion, a locking portion, a fastening portion, a reinforcing portion, an insulator, or a tape, for example. In the first embodiment, the fixing portion 60 comprises a first member 61 and a second member 62.
The first member 61 is a flexible sheet, which is made of a material having insulation property such as polyester, for example. The first member 61 may be made of another material. The first member 61 comprises a first attaching portion 64 and a second attaching portion 65. The first attaching portion 64 and the second attaching portion 65 can also be referred to as portions, sections, or areas, for example.
The first attaching portion 64 is attached to the third portion 57c by being wound around the third portion 57c of the locking lever 57. In other words, the first attaching portion 64 wraps the third portion 57c. The first attaching portion 64 is thus a portion of the first member 61, which is fastened with a double-sided adhesive tape, for example, in the state where the first attaching portion 64 is wound around the third portion 57c. 
A portion of the first attaching portion 64 is between the third portion 57c of the locking lever 57 at the first position P1 and the leads 52 on the mounting face 41 of the substrate 37. The portion of the first attaching portion 64 insulates the third portion 57c from the leads 52. The portion of the first attaching portion 64 also insulates the third portion 57c from wiring patterns provided on the mounting face 41.
The second attaching portion 65 continues from the first attaching portion 64. The second attaching portion 65 extends from the first attaching portion 64 toward a side opposite the female connector 43. The second attaching portion 65 may extend in another direction. The first attaching portion 64 rotating with respect to the third portion 57c of the locking lever 57 allows the second attaching portion 65 to also rotate with respect to the third portion 57c. 
The second member 62 is a flexible sheet, which is made of a material having insulation property such as polyester, for example. The second member 62 is stuck on the upper face 51e of the first casing 51 and the upper face 56c of the second casing 56 with a double-sided adhesive tape, for example. The second member 62 is thus attached to the female connector 43 and the male connector 47.
The second member 62 fixes the female connector 43 in such a state that the female connector 43 is connected to the male connector 47 by sticking on the female connector 43 and the male connector 47 that are connected to each other. The second member 62 prevents the male connector 47 from separating from the female connector 43 with adhesion force.
In addition, the second member 62 is stuck on the second attaching portion 65 of the first member 61 with a double-sided adhesive tape, for example. The second member 62 may be furthermore stuck on the first attaching portion 64.
The sticking force of the second member 62 to the first member 61 is equal to or larger than the sticking force of the second member 62 to the female connector 43 and the male connector 47. It is noted that, the sticking force of the second member 62 to the first member 61 may be smaller than the sticking force of the second member 62 to the female connector 43 and the male connector 47.
The second attaching portion 65 of the first member 61 and the second member 62 stuck on the second attaching portion 65 extend toward a direction approximately along the Y axis. The first member 61 and the second member 62 may extend in another direction.
The second member 62 is furthermore stuck on the surface 49a of the harness 49 with a double-sided adhesive tape, for example. The second member 62 may be a portion of the harness 49. An insulation layer that forms the FPC may be the second member 62 in case the FPC is attached to the male connector 47 instead of the harness 49. In other words, the second member 62 may be integrated with the FPC.
The male connector 47 is removed from the female connector 43 in the following manner, for example. It is noted that, the manner to remove the male connector 47 from the female connector 43 is not limited to the manner described below.
The second attaching portion 65 of the first member 61 and the second member 62 stuck on the second attaching portion 65 are pinched by an operator, for example. As illustrated in FIG. 5, the locking lever 57 is rotated when the first member 61 and the second member 62 are pulled by the operator in a direction along the Z axis, for example. Thus, the first attaching portion 64 of the first member 61 pushes the third portion 57c of the locking lever 57 from the first position P1 toward the second position P2. In other words, the first attaching portion 64 causes a force to act on the locking lever 57 to move the locking lever 57 from the first position P1 to the second position P2.
The second position P2 is further away from the mounting face 41 of the substrate 37 than the first position P1. As a result of the rotation, the locking lever 57 moves away from the substrate 37. It is noted that, the second position is not limited to this example, the second position may be closer to the mounting face 41 of the substrate 37 than the first position is.
When the first member 61 and the second member 62 are pulled, the second member 62 of the fixing portion 60 is peeled from the female connector 43. In other words, the second member 62 of the fixing portion 60 is separated from the female connector 43 together with the locking lever 57.
Separating the second member 62 of the fixing portion 60 from the female connector 43 leads to the movement of the locking lever 57 from the first position P1 to the second position P2. Separated from the female connector 43, the fixing portion 60 causes the locking lever 57 to move from the first position P1 to the second position P2. In other words, the fixing of the male connector 47 to the female connector 43 by the locking lever 57 and the fixing portion 60 is released simply by pulling of the fixing portion 60.
The action described above can be expressed in another way. For example, in the state where the second member 62 is attached to the female connector 43, a portion of the first attaching portion 64 is on a side opposite the second position P2 with respect to the third portion 57c of the locking lever 57 at the first position P1. When the first member 61 and the second member 62 are pulled, the portion of the first attaching portion 64 lifts up the third portion 57c of the locking lever 57 and causes the locking lever 57 to move to the second position P2. In the state where the second member 62 is separated from the female connector 43, the portion of the first attaching portion 64 is on a side of the second position P2 with respect to the first position P1.
As described above, moving to the second position P2, the locking lever 57 disengages the female connector 43. The male connector 47 is removed from the female connector 43 by being pulled in a direction along the Y axis by an operator, for example.
The second member 62 of the fixing portion 60 may be fixed to the male connector 47 with a pin or an adhesive, for example. In this case, the fixing portion 60 having caused the locking lever 57 to move from the first position P1 to the second position P2 is further pulled, resulting in the male connector 47 being removed from the female connector 43. The male connector 47 is removed from the female connector 43 simply by pulling of the fixing portion 60.
In the portable computer 10 in the first embodiment, the fixing portion 60 fixes the male connector 47 to the female connector 43. In addition, the fixing portion 60 is separated from the female connector 43 to move the locking lever 57 from the first position P1 to the second position P2. In this way, the fixing portion 60 is configured to fix the male connector 47 to the female connector 43 and to cause the locking lever 57 to move. The fixing portion 60 thus configured can reduce the number of components of the portable computer 10.
The following describes a second embodiment with reference to FIGS. 6 and 7. In the following description on the multiple embodiments, elements having the same functions as those of already described elements may be labeled with the same numerals, and descriptions thereof may be omitted. The elements labeled with the same numerals may not have all of the functions and characteristics in common with each other, and may have different functions and characteristics in accordance with the respective embodiments.
FIG. 6 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the first position P1, according to the second embodiment. FIG. 7 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the second position P2. In FIG. 7, the locking lever at the first position P1 is indicated with the chain double-dashed line.
As illustrated in FIG. 6, the fixing portion 60 in the second embodiment is a flexible sheet, which is made of a material having insulation property such as polyester, for example. The fixing portion 60 comprises an intermediate portion 71, a first extending portion 72, and a second extending portion 73. The intermediate portion 71, the first extending portion 72, and the second extending portion 73 can also be referred to as portions, sections, or areas, for example.
The intermediate portion 71 is wound around the third portion 57c of the locking lever 57. In other words, the intermediate portion 71 surrounds the third portion 57c. A portion of the intermediate portion 71 is on a side opposite the second position P2 with respect to the third portion 57c of the locking lever 57 at the first position P1. The portion of the intermediate portion 71 is between the third portion 57c of the locking lever 57 and the substrate 37.
The first extending portion 72 extends from one end of the intermediate portion 71. In other words, the first extending portion 72 continues from the intermediate portion 71. The first extending portion 72 is stuck on the upper face 51e of the first casing 51 and the upper face 56c of the second casing 56 with a double-sided adhesive tape, for example. Attached to the female connector 43 and the male connector 47, the first extending portion 72 fixes the male connector 47 in such a state that the male connector 47 is connected to the female connector 43.
The second extending portion 73 extends from the other end of the intermediate portion 71. The second extending portion 73 is fixed to the first extending portion 72 with a double-sided adhesive tape, for example. In other words, the second extending portion 73 is attached to the female connector 43 via the first extending portion 72 on the female connector 43. A tip portion 73a of the second extending portion 73 is not fixed to the first extending portion 72, and is free.
In another expression, the fixing portion 60 is stuck on the female connector 43 and the male connector 47, and folded back such that the fixing portion 60 turns around the third portion 57c of the locking lever 57. The folded-back portion of the fixing portion 60 is stuck on a portion of the fixing portion 60 stuck on the female connector 43 and the male connector 47.
The male connector 47 in the second embodiment is removed from the female connector 43 in the following manner, for example. The manner to remove the male connector 47 from the female connector 43 is not limited to the manner described below.
The tip portion 73a of the second extending portion 73 is pinched by an operator, for example. The operator readily pinches the tip portion 73a because the tip portion 73a is free. When the tip portion 73a of the second extending portion 73 is pulled in a direction along the Z axis, for example, the second extending portion 73 is peeled from the first extending portion 72.
As illustrated in FIG. 7, when the second extending portion 73 having been peeled from the first extending portion 72 is further pulled, the intermediate portion 71 comes into contact with the third portion 57c of the locking lever 57. The intermediate portion 71 pushes the third portion 57c of the locking lever 57 from the first position P1 toward the second position P2.
The intermediate portion 71 lifts up the locking lever 57, resulting in the first extending portion 72 being peeled from the female connector 43. In other words, the first extending portion 72 of the fixing portion 60 is separated from the female connector 43.
Separating the first extending portion 72 of the fixing portion 60 from the female connector 43 leads to the movement of the locking lever 57 from the first position P1 to the second position P2. Thus, separated from the female connector 43, the fixing portion 60 causes the locking lever 57 to move from the first position P1 to the second position P2.
Moving to the second position P2, the locking lever 57 disengages the female connector 43. The male connector 47 is removed from the female connector 43 by being pulled in a direction along the Y axis by an operator, for example.
The following describes a third embodiment with reference to FIG. 8. FIG. 8 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the second position P2, according to the third embodiment. In FIG. 8, the locking lever 57 at the first position P1 is indicated with the chain double-dashed line.
As illustrated in FIG. 8 with the chain double-dashed line, the second extending portion 73 in the third embodiment is stuck on the mounting face 41 of the substrate 37 with a double-sided adhesive tape, for example. The second extending portion 73 is attached to the substrate 37, not to the first extending portion 72.
In the state where the first extending portion 72 is attached to the female connector 43, a portion of the intermediate portion 71 is on a side opposite the second position P2 with respect to the third portion 57c of the locking lever 57 at the first position P1. The intermediate portion 71 is not wound around the third portion 57c. 
When the male connector 47 is removed from the female connector 43, the second extending portion 73 is peeled from the substrate 37 by an operator, for example. The second extending portion 73 having been peeled is pulled in a direction along the Z axis, for example, causing the locking lever 57 to move from the first position P1 to the second position P2 and resulting in the first extending portion 72 being separated from the female connector 43.
The following describes a fourth embodiment with reference to FIGS. 9 and 10. FIG. 9 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the first position P1, according to the third embodiment. FIG. 10 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the second position P2. In FIG. 10, the locking lever 57 at the first position P1 is indicated with the chain double-dashed line.
As illustrated in FIG. 9, the fixing portion 60 in the fourth embodiment comprises an attaching portion 77 and an extending portion 78. The attaching portion 77 and the extending portion 78 can also be referred to as portions, sections, or areas, for example.
The attaching portion 77 is attached to the third portion 57c by being wound around the third portion 57c of the locking lever 57. The attaching portion 77 is thus a portion of the fixing portion 60, which is fastened with a double-sided adhesive tape, for example, in the state where the portion is wound around the third portion 57c. 
The extending portion 78 continues from the attaching portion 77. The extending portion 78 extends from the attaching portion 77 toward the female connector 43. The extending portion 78 is stuck on the upper face 51e of the first casing 51 and the upper face 56c of the second casing 56 with a double-sided adhesive tape, for example. The extending portion 78 fixes the female connector 43 to the male connector 47.
The male connector 47 is removed from the female connector 43 in the following manner, for example. The manner to remove the male connector 47 from the female connector 43 is not limited to the manner described below.
The extending portion 78 is peeled from the male connector 47 and the female connector 43 by an operator, for example. In other words, the extending portion 78 of the fixing portion 60 is separated from the female connector 43.
As illustrated in FIG. 10, the extending portion 78 having been peeled from the male connector 47 and the female connector 43 is pulled in a direction along the Z axis, for example, resulting in the locking lever 57 being rotated. The attaching portion 77 pushes the third portion 57c of the locking lever 57 from the first position P1 toward the second position P2. In other words, the attaching portion 77 causes a force to act on the locking lever 57 to move the locking lever 57 from the first position P1 to the second position P2.
Separating the extending portion 78 of the fixing portion 60 from the female connector 43 leads to the movement of the locking lever 57 from the first position P1 to the second position P2. Separated from the female connector 43, the fixing portion 60 causes the locking lever 57 to move from the first position P1 to the second position P2.
Moving to the second position P2, the locking lever 57 disengages the female connector 43. The male connector 47 is removed from the female connector 43 by being pulled in a direction along the Y axis by an operator, for example.
The following describes a fifth embodiment with reference to FIG. 11. FIG. 11 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the second position P2, according to the fifth embodiment. In FIG. 11, the locking lever 57 at the first position P1 is indicated with the chain double-dashed line.
As illustrated in FIG. 11, the locking lever 57 in the fifth embodiment comprises an expanded portion 81. The expanded portion 81 can also be referred to as a covering portion, a stuck portion, an attached portion, or a coated portion, for example.
The expanded portion 81 is a resin covering the third portion 57c of the locking lever 57. The expanded portion 81 is not limited to this example, the expanded portion 81 may be another member attached to the third portion 57c in a detachable manner, for example.
The expanded portion 81 has a cross section of an ellipse. The circumferential length of the cross section of the expanded portion 81 is larger than that of the cross section of the third portion 57c. The width in the longitudinal direction of the cross section of the expanded portion 81 is larger than the diameter of the third portion 57c. The expanded portion 81 is the portion expanded to be larger than the third portion 57c. The shape of the expanded portion 81 is not limited to this example, the shape of the expanded portion 81 may be another shape such as a cylindrical shape having a radius larger than the third portion 57c, a platy shape, or a wave shape, for example.
The fixing portion 60 is stuck on an upper face 81a of the expanded portion 81 with a double-sided adhesive tape, for example. In other words, the fixing portion 60 is attached to the locking lever 57 by adhesion. The upper face 81a of the expanded portion 81 faces a side opposite the side facing the mounting face 41 of the substrate 37. A lower face 81b, which is opposite the upper face 81a, of the expanded portion 81 faces the mounting face 41, and the fixing portion 60 is not between the locking lever 57 and the mounting face 41. The fixing portion 60 or another member may be between the fixing portion 60 and the mounting face 41.
The fixing portion 60 further comprises a tongue 84. The tongue 84 extends from a portion where the fixing portion 60 is stuck on the expanded portion 81 in a direction opposite the female connector 43. The tongue 84 is not fixed to any other portion, and is free. It is noted that, the tongue 84 may be fixed to another component such as the substrate 37, for example.
The male connector 47 is removed from the female connector 43 in the following manner, for example. The manner to remove the male connector 47 from the female connector 43 is not limited to the manner described below.
The tongue 84 is pinched by an operator, for example. The operator readily pinches the tongue 84 because the tongue 84 is free. When the tongue 84 is pulled in a direction along the Z axis, for example, the locking lever 57 is rotated. The fixing portion 60 pulls the expanded portion 81 of the locking lever 57 from the first position P1 toward the second position P2. In other words, the fixing portion 60 causes a force to act on the locking lever 57 to move the locking lever 57 from the first position P1 to the second position P2.
The sticking force of the fixing portion 60 to the expanded portion 81 is larger than a force for starting to rotate the locking lever 57. Thus, the fixing portion 60 keeps stuck on the expanded portion 81 even though the locking lever 57 is rotated by the fixing portion 60 pulling the expanded portion 81.
Pulling the expanded portion 81, the fixing portion 60 peels from the female connector 43. In other words, the fixing portion 60 is separated from the female connector 43.
Separating the fixing portion 60 from the female connector 43 leads to the movement of the locking lever 57 from the first position P1 to the second position P2. Separated from the female connector 43, the fixing portion 60 causes the locking lever 57 to move from the first position P1 to the second position P2.
Moving to the second position P2, the locking lever 57 disengages the female connector 43. The male connector 47 is removed from the female connector 43 by being pulled in a direction along the Y axis by an operator, for example.
The following describes a sixth embodiment with reference to FIG. 12. FIG. 12 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the second position P2, according to the sixth embodiment. In FIG. 12, the locking lever 57 that is at the first position P1 is indicated with the chain double-dashed line.
As illustrated in FIG. 12, the expanded portion 81 in the sixth embodiment is integrated with the locking lever 57. The expanded portion 81 is a portion of the third portion 57c and is the portion expanded to be larger than another portion of the third portion 57c. The expanded portion 81 is not limited to this example. For example, the expanded portion 81 may have the same radius as that of another portion of the third portion 57c and may be bended to have a wave-like shape.
The upper face 81a of the expanded portion 81 is a plane in parallel with the upper face 51e of the first casing 51 in the state where the locking lever 57 is at the first position P1. The upper face 81a may be a curved surface. The fixing portion 60 is stuck on the upper face 81a. 
When the male connector 47 is removed from the female connector 43, the tongue 84 is pulled in a direction along the Z axis by an operator, for example. Pulling the tongue 84 causes the locking lever 57 to move from the first position P1 to the second position P2 and the fixing portion 60 to be separated from the female connector 43.
The following describes a seventh embodiment with reference to FIG. 13. FIG. 13 is a cross-sectional view illustrating a portion of the display module 32 in the state where the locking lever 57 is at the second position P2, according to the seventh embodiment. In FIG. 13, the locking lever 57 that is at the first position P1 is indicated with the chain double-dashed line.
As illustrated in FIG. 13 in the seventh embodiment, the male connector 47 is connected to the female connector 43 in a direction perpendicular to the mounting face 41 of the substrate 37. The male connector 47 may be connected to the female connector 43 at an angle other than the right angle.
The female connector 43 has an upper surface 43a and a side surface 43b. The upper surface 43a faces a side opposite the side facing the mounting face 41 of the substrate 37. The upper surface 43a is provided with the insertion inlet. The side surface 43b intersects the upper surface 43a. 
The male connector 47 has a lower surface 47a and a side surface 47b. The lower surface 47a has the insertion portion. The male connector 47 is connected to the female connector 43 by insertion of the insertion portion into the insertion inlet of the female connector 43. The side surface 47b intersects the lower surface 47a. In the state where the male connector 47 is connected to the female connector 43, the side surface 47b faces in the same direction as the side surface 43b of the female connector 43 faces. The side surface 47b of the male connector 47 substantially continues from the side surface 43b of the female connector 43.
The locking lever 57 engages the female connector 43 in the state where the locking lever 57 is at the first position P1. For example, the stoppers provided to the female connector 43 engage the locking lever 57. The side surface 43b of the female connector 43 faces the third portion 57c of the locking lever 57 at the first position P1.
The fixing portion 60 fixes the male connector 47 to the female connector 43 by being stuck on the side surface 43b of the female connector 43 and the side surface 47b of the male connector 47. A portion of the fixing portion 60 is between the third portion 57c of the locking lever 57 at the first position P1 and the side surface 43b of the female connector 43.
In addition, the fixing portion 60 has a tip portion 60a extending along the mounting face 41 of the substrate 37. The tip portion 60a is not fixed to any other component, and is free. It is noted that, the tip portion 60a may be fixed to another component such as the substrate 37.
The male connector 47 is removed from the female connector 43 in the following manner, for example. The manner to remove the male connector 47 from the female connector 43 is not limited to the manner described below.
The tip portion 60a of the fixing portion 60 is pinched by an operator, for example. The operator readily pinches the tip portion 60a because the tip portion 60a is free. When the tip portion 60a is pulled in a direction along the Z axis, for example, the fixing portion 60 is peeled from the female connector 43.
The tip portion 60a of the fixing portion 60 is further pulled, resulting in the fixing portion 60 coming into contact with the third portion 57c of the locking lever 57. The fixing portion 60 pushes the third portion 57c of the locking lever 57 from the first position P1 toward the second position P2.
The fixing portion 60 lifts up the locking lever 57 and peels from the female connector 43 and the male connector 47. In other words, the fixing portion 60 is separated from the female connector 43.
Separating the fixing portion 60 from the female connector 43 leads to the movement of the locking lever 57 from the first position P1 to the second position P2. Separated from the female connector 43, the fixing portion 60 causes the locking lever 57 to move from the first position P1 to the second position P2.
Moving to the second position P2, the locking lever 57 disengages the female connector 43. The male connector 47 is removed from the female connector 43 by being pulled in a direction along the Z axis by an operator, for example.
According to at least one embodiment described above, the fixing portion fixes the first connector to the second connector. In addition, the fixing portion causes the engage portion to move from the first position to the second position by being separated from the second connector. The fixing portion thus configured to fix the first connector to the second connector and cause the engage portion to move reduces the number of components of the electronic device.
