For example, when the first housing 30 and the second housing 70 are fitted to each other, even if the first metal fitting 50 is somewhat elastically deformed in an oblique fitting state, the convex portion formed on the second housing 70 76 supports the first metal fitting 50. Therefore, the electrical connector 10 can prevent excessive deformation of the first metal fitting 50.
- the electrical connector 10 can appropriately protect the metal fitting and the housing at the time of fitting because the protrusion 36 of the first housing 30 is located on the fitting side with respect to the first metal fitting 50. Even when the relative positions of the first connector 20 and the second connector 60 are slightly shifted in the front-rear and left-right directions during the fitting, the portion that first contacts the second connector 60 is the protrusion 36. As described above, the electrical connector 10 contacts the part of the second connector 60 before the first metal fitting 50 is inserted into an appropriate position during fitting, and the metal fitting is excessively deformed or the housing is damaged. Can be prevented.
- the convex portion 76 By fitting the convex portion 76 with the concave portion 35, the first connector 20 and the second connector 60 are attracted to each other during the fitting. Therefore, in the electrical connector 10, the first connector 20 and the second connector 60 can be easily fitted to each other. Similarly, the fitting of the convex portion 76 and the concave portion 35 facilitates positioning of the other of the first connector 20 and the second connector 60 relative to one other.
- the electrical connector 10 can improve the fitting force of the first connector 20 and the second connector 60 by the fitting structure by the convex portion 76 and the concave portion 35. Thus, even when the electrical connector 10 is in a miniaturized state, the fitting force can be improved.
- the electrical connector 10 can strengthen the connection between the first connector 20 and the second connector 60 by engaging the first metal fitting 50 and the second metal fitting 90.
- the protruding portion 54 of the first metal fitting 50 is exposed to the outside of the first housing 30, so that the corresponding portion does not need to be covered with the first housing 30, and the first connector 20 can be miniaturized.
- the electrical connector 10 can reduce the size of the first connector 20 in the arrangement direction of the first contacts 40, that is, in the left-right direction.
- the first connector 20 can contribute to space saving of the entire circuit board CB1 by reducing the area occupied by the circuit board CB1.
- the protrusion 54 is formed in a bifurcated shape, so that the first metal fitting 50 is easily elastically deformed to some extent.
- the electrical connector 10 can further reduce the size of the first connector 20 because the first housing 30 is not interposed between the forked portions of the protruding portion 54.
- the electrical connector 10 can ensure the amount of elastic deformation to the inside of the protruding portion 54 of the first metal fitting 50 when fitted. Therefore, even in a miniaturized state, the engagement force between the first metal fitting 50 and the second metal fitting 90 is improved.
- the electrical connector 10 can reduce the size of the first connector 20 in the left-right direction by directing the second contact portion 55 of the first metal fitting 50 in the front-rear direction. Since the second contact portion 55 of the first metal fitting 50 is provided at the forked portion of the protrusion 54 along the front-rear direction, and the protrusion 54 elastically deforms in the front-rear direction when engaged with the second metal fitting 90, It is not necessary to provide a space for elastic deformation of the first metal fitting 50 in the left-right direction. On the other hand, since the concave portion 35 is located between the forked portions of the protruding portion 54, the electrical connector 10 can secure an elastic deformation space of the first metal fitting 50 in the front-rear direction. Thus, since the engagement structure of the 1st metal fitting 50 and the 2nd metal fitting 90 is along the front-back direction, the electrical connector 10 can be reduced in size in the left-right direction as a whole.
- the electrical connector 10 can allow some elastic deformation of the protruding portion 54 due to the gap S formed between the protruding portion 54 and the protruding portion 76 after fitting. Thereby, the electrical connector 10 can strengthen the engagement of the first metal fitting 50 and the second metal fitting 90 and can improve the fitting force between the first connector 20 and the second connector 60. The electrical connector 10 can maintain contact stability between the first metal fitting 50 and the second metal fitting 90 even in a miniaturized state. On the other hand, the electrical connector 10 can prevent excessive deformation of the metal fittings even in downsizing due to the close arrangement of the first metal fitting 50 and the convex portion 76 and the configuration of the protrusions 36. Since excessive elastic deformation of the first metal fitting 50 is restricted by the convex portion 76, the electrical connector 10 can reduce the possibility that the first metal fitting 50 is excessively deformed during fitting.
- the first housing 30 can be more easily guided into the second housing 70 by forming the protrusion 36 to be tapered toward the fitting side.
- the electrical connector 10 can convert the pushing force in the fitting direction of the first connector 20 into the drawing force directed to the inside of the fitting recess 73 by the inclined surface of the protrusion 36 contacting the second housing 70. Thereby, in the electrical connector 10, the fitting between the first connector 20 and the second connector 60 is further facilitated.
- the electrical connector 10 is provided with the recess 35 so as to be recessed in the arrangement direction of the first contacts 40, that is, in the left-right direction, thereby facilitating positioning of the first housing 30 and the second housing 70 in the left-right direction.
- the electrical connector 10 by causing the shape of the convex portion 76 to correspond to the concave portion 35, it is further facilitated to be guided when the first connector 20 and the second connector 60 are fitted. In the electrical connector 10, the fitting between the first connector 20 and the second connector 60 is further facilitated. Similarly, the electrical connector 10 can further improve the fitting force between the first connector 20 and the second connector 60.
- the electrical connector 10 is provided with a guiding portion 77 at the upper end of the convex portion 76 of the second housing 70, so that the guiding when the first connector 20 is fitted is further facilitated. Therefore, the fitting of the first connector 20 and the second connector 60 is further facilitated.
- the electrical connector 10 can realize a retaining action by the protrusion 95 of the second metal fitting 90 serving as a climbing wall in the direction of removal of the first connector 20.
- the electrical connector 10 can improve the holding force at the time of fitting.
- FIG. 11 is an enlarged cross-sectional view corresponding to FIG. 9 showing a modification of the electrical connector 10 according to the embodiment.
- the side surface 76c of the convex portion 76 of the second housing 70 along the direction perpendicular to the outer surface A1, that is, the left-right direction may not be parallel to the left-right direction.
- the side surface 76c of the convex portion 76 may be an arbitrary inclined surface that is inclined with respect to the left-right direction, or may be an arbitrary curved surface.
- the structure of the concave portion 35 of the first housing 30 and the convex portion 76 of the second housing 70 may be interchanged so that the first housing 30 has a convex portion and the second housing 70 has a corresponding concave portion.
- the position of the fitting surface with respect to the left-right direction of the convex portion 76 of the second housing 70 is not limited to the position shown in FIG. 9, and the arbitrary position at which the convex portion 76 can restrict excessive elastic deformation of the first metal fitting 50. It may be.
- the fitting surface may be located slightly to the left of the right end surfaces of the first metal fitting 50 and the second metal fitting 90.
