For example, as shown in Fig. 12, three engagement recesses 4k to 4k are formed in the outer contact portion 4c of the first contact 4 of the first connector 1, and the engagement recesses 4k to 4k. The contact portion 10e of the inner contact piece 10b of the second contact 10 of the second connector 2 can be slidably engaged in three steps.

According to the invention of claim 1, the connector is formed of a first connector accommodating a connection object and a second connector mounted on a substrate, and at the same time the second housing of the second connector is slidably engaged to the outside of the first connector, Since the inner contact portion of the second contact of the second connector is formed in contact with the outer contact portion of the first contact of the first connector during this sliding, when the connector is mounted on a substrate, the distance from the substrate to the connection object is appropriately determined. Can be varied. Therefore, it is possible to provide a connector adaptable to a plurality of electronic devices having different distances from the board to the connection object.

According to the invention of claim 2, in the invention of claim 1, one of the outer contact portion of the first contact and the inner contact portion of the second contact is formed of a fixed contact piece that is long in the sliding direction of the first and second connectors, and the other. Since the side is formed at the free end side of the letter spring piece, the shape of the outer contact portion of the first contact and the inner contact portion of the second contact can be simplified.

According to the invention of claim 3, in the invention of claim 2, the outer contact portion of the first contact exposed to the outside of the first contact is formed as a fixed contact piece, and the inner side of the second contact is located inside the second connector. Since the contact portion is formed on the free end side of the letter spring piece, unnecessary force is applied to the inner contact portion of the second contact during handling of the second connector, thereby preventing the spring property from being impaired, and the handling of the first and second connectors. Can be facilitated.

In the invention according to claim 4, in the invention according to claim 2 or 3, a plurality of stage engagement portions that can be engaged stepwise with the free end side contact portions of the letter spring pieces are formed in the fixed connection piece when sliding the first and second connectors. When mounting a connector on a board | substrate, the distance from a board | substrate to a connection object can be changed in steps.

In the invention of claim 5, in the invention of claim 1, 2, 3 or 4, the second connector is formed in a shape that can be inserted into the connector attachment hole of the board other than the connection portion of the second contact at the time of mounting on the board. Therefore, the connecting portion of the second connector can be soldered to the printed circuit from either the front side or the back side of the substrate without inverting the upper and lower sides of the second connector, and the connecting portion of the second contact is turned upside down. The printed circuit can be connected to either the front side or the back side of the substrate.

In the invention according to claim 6, in the invention according to claim 1, 2, 3, 4, or 5, the connecting object is a camera module, and the first housing is formed in a shape of a shape having an accommodating recess opening upward. Since the two housings are formed in a frame shape, the present invention can be used for a camera module socket mounted on a substrate, and the distance from the surface of the substrate to the top surface of the camera module can be varied suitably. For example, when using a mobile phone with a camera, the same camera module socket can be used for a plurality of camera-equipped mobile phones having different distances from the substrate surface to the top surface of the camera module.
