  Thus, in the electrical connector mounted on the mounting destination member such as the printed wiring board or the substrate, an external force is applied from the mating electrical connector fitted to the electrical connector in the fitting direction or in a direction intersecting the fitting direction. When received, the solder formed between the electrical connector and the mounting destination member receives a force, and when the external force becomes excessive, the solder is broken and the electrical connector peels from the mounting destination member. For such an electrical connector, there is a strong desire to increase the peel strength of the electrical connector from the mounting destination member while making the mounting area, which is the projected area of the electrical connector onto the mounting destination member, as compact as possible. Yes.

  The present invention has been made paying attention to such points, and the object of the present invention is to use a shield shell to form a plate on which a solder having a thick fillet is formed on the fitting side. A plate that is provided with a piece to increase the peel strength when receiving an external force that mainly lifts the fitting side of the electrical connector from the mounting member, and forms a solder having a fillet that is longer than the fitting side. An object of the present invention is to provide an electrical connector that is provided in a compact manner and has a peel strength that is enhanced when it receives an external force along the mounting surface of the mounting member.

In order to achieve the above object, the first electrical connector of the present invention comprises:
Taking a thickness direction, a width direction, and a depth direction orthogonal to each other, when one side of the thickness direction is a mounting side and the other side is an anti-mounting side,
An inner housing formed of an insulating material;
A contact portion formed of a conductive material, extending to the mounting side, and having a contact portion and provided in the inner housing;
A shell formed of a conductive material plate, and provided with an inner housing portion and an inner housing portion that accommodates the contact and opens to the front in the depth direction. Is
Two vertical plate portions facing the width direction and facing the width direction;
One lateral plate portion that is oriented in the thickness direction and has both end edges in the width direction connected to the opposite edge of the two vertical plate portions on the opposite mounting side,
Ends of the two vertical plate portions of the shell in front of the depth direction are respectively bent outward in the width direction, and the first dimension for mounting in which the dimension in the thickness direction is larger than the plate thickness of the shell. A piece is provided,
All of the two vertical plate portions of the shell except the first piece at the end on the mounting side are bent outward in the width direction to provide a second piece for mounting ,
An electrical connector configured to solder the first piece and the second piece of the shell to a mounting surface of a mounting destination member .

  When the first piece and the second piece of the shell are soldered to the mounting surface of the mounting member, the electrical connector is mounted on the mounting member. In that case, a solder fillet is formed between the outer peripheral surface extending from the periphery of at least the mounting side surface of the first piece to the anti-mounting side and the mounting destination member, but the thickness of the first piece is the same. The dimension in the length direction is larger than the plate thickness of the shell. Therefore, the fillet is relatively thick. Therefore, on the fitting side of the electrical connector, the fitting side of the electrical connector is mainly formed by the relatively thick fillet. The peel strength against the external force that lifts the mounting target member from the mounting destination member is increased. In addition, a solder fillet is formed between the outer peripheral surface extending from at least the peripheral edge of the mounting side surface of the second piece to the anti-mounting side and the mounting destination member, and the second piece is formed of the shell. The vertical plate portion is formed in a rectangular shape in which the dimension in the depth direction is the longitudinal direction and the dimension in the width direction is the short direction. Therefore, since the fillet is relatively long, the peeling strength against the external force mainly along the mounting surface of the mounting member is increased by the fillet having a long overall length behind the fitting side of the electrical connector. . Further, since the end portion of the shell is bent to form the first piece and the second piece, the electrical connector is compactly accommodated.

The second electrical connector of the present invention is the first electrical connector, further comprising:
The electrical connector is provided with openings penetrating in the width direction on the back side in the depth direction of the two vertical plate portions.

  In this way, when the fitting side of the electrical connector receives the external force along the width direction, the vertical plate portion near the opening is more easily elastically deformed than the other portions. By absorbing and dispersing the stress generated by the external force, the stress applied to the solder is reduced.

The third electrical connector of the present invention is the second electrical connector, further comprising:
In the electrical connector, the shell is provided with a cover for closing the two openings of the shell.

  If it does in this way, since the said opening will be block | closed with the said cover, the shielding effect of the said shell is ensured.

The fourth electrical connector of the present invention is the third electrical connector, further comprising:
Of each of the vertical plate portions and each of the corresponding covers, one is provided with a convex portion protruding in the width direction, and the other is provided with a concave portion that is recessed in the width direction and into which the convex portion is inserted. It is a connector.

  If it does in this way, at the time of manufacture of the above-mentioned shell, positioning of each above-mentioned cover to each above-mentioned vertical board part becomes easy. Further, when the fitting side of the electrical connector receives various external forces, the vertical plate portions and the corresponding covers are restricted from being relatively displaced.

The fifth electrical connector of the present invention is the electrical connector according to any one of the first to fourth electrical connectors,
It is an electrical connector provided with an external housing formed of an insulating material and provided therein so as to form an outer housing portion that houses at least the fitting side of the shell.

  If it does in this way, the rigidity of the said shell, the improvement of the connection strength with the other party electrical connector, etc. will be performed by the said external housing, for example.

  The first electrical connector according to the present invention is provided mainly by using the shell for shielding, and providing the first piece so that the solder having the thick fillet is formed on the fitting side. The second such that the peel strength when receiving the external force that lifts the fitting side from the mounting member is increased, and the solder having the fillet that is longer in the back than the fitting side is formed. It was possible to provide the electrical connector that is provided in a compact manner and has a peel strength that is increased when the external force along the mounting surface of the mounting destination member is mainly applied and is compactly accommodated.

  In the second electrical connector of the present invention, in addition to obtaining the effect obtained by the first electrical connector, the fitting side of the electrical connector receives the external force along the width direction. The stress applied to the solder can be reduced by absorbing and dispersing the stress generated by the external force.

  The third electrical connector of the present invention can secure the shielding effect of the shell by the cover, in addition to the effect obtained by the second electrical connector.

  According to the fourth electrical connector of the present invention, in addition to obtaining the effect obtained by the third electrical connector, the positioning of the respective covers with respect to the respective longitudinal plate portions is facilitated at the time of manufacturing the shell. In addition, when the fitting side of the electrical connector receives various external forces, it is possible to restrict relative displacement between the vertical plate portions and the corresponding covers. .

  According to the fifth electrical connector of the present invention, in addition to obtaining the effect obtained by any one of the first to fourth electrical connectors, the outer housing can further enhance the rigidity of the shell, for example. The connection strength with the side electrical connector can be improved.
