  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a connector device for electrically connecting a plurality of connection portions formed in parallel in a predetermined arrangement direction on a circuit board and a plurality of cables.

  As such a connector device, a plurality of substrate side contacts respectively connected to a plurality of connection portions on a circuit board, a substrate side connector having a substrate side housing for holding the substrate side contacts, and a plurality of cables A plurality of cable-side contacts to be connected and a cable-side connector having a cable-side housing for holding the cable-side contacts, and the substrate-side housing and the cable-side housing are fitted to each other There is known a connector device which electrically connects a plurality of connection portions on a substrate and a plurality of cables by bringing the two into contact with each other (see, for example, Patent Document 1). In such a connector device, generally, the arrangement pitch of the contacts is set to correspond to the interval (wiring pitch) of the wiring (connection portion) formed on the circuit board. In recent years, the narrowing of wiring pitches in circuit boards has progressed, and in order to cope with this, the arrangement pitch of each contact tends to be narrow.

JP 2017-130321 A

  When the wiring pitch on the circuit board becomes narrow, the cables connected to the contacts arranged in parallel at the corresponding arrangement pitch need to use a cable with a core wire (electric wire) thinner than the concerned wiring pitch (arrangement pitch) is there. For example, in a small connector device formed on a circuit board at a wiring pitch of 0.5 mm and corresponding to the contacts arranged side by side at an arrangement pitch of 0.5 mm, the thickness of the core wire is It is necessary to use a cable of 0.5 mm or less. There is a problem that such an extra-thin cable is difficult to handle in manufacturing, for example, it is easy to break when soldering to a contact, and the cable itself is expensive.

  The present invention has been made in view of such problems, and it is possible to use an inexpensive cable that is thicker than the wiring pitch on the circuit board and has good communication characteristics, and a cable that is not easily damaged in manufacturing. An object of the present invention is to provide a connector device that can be used.

In order to achieve the above object, according to the present invention, a plurality of substrate side contacts respectively connected to a plurality of connection portions formed in a lateral direction on a circuit board and the plurality of substrate side contacts are arrayed in the lateral direction A cable-side housing that holds a substrate-side connector having a substrate-side housing that holds in an elastic state, a plurality of cable-side contacts respectively connected to a plurality of cables, and the plurality of cable-side contacts aligned in the left-right direction And a cable-side connector having the above-mentioned components, and the connector on the substrate and the cable are electrically connected by bringing the substrate-side contact and the cable-side contact into contact with each other. Further, the substrate side contacts are a plurality of first substrate side contacts arranged in parallel at a predetermined arrangement pitch in the left and right direction on the front and rear one side of the substrate side housing, and the other front and rear side of the substrate side housing A plurality of second substrate contacts arranged in parallel at the arrangement pitch in the lateral direction are provided at positions shifted in the left and right direction by half of the arrangement pitch with respect to the first substrate side contacts. The cable-side contacts are arranged in parallel at the arrangement pitch in the left-right direction on the front and rear one side of the cable-side housing, and a plurality of first cable-side contacts respectively contacting the plurality of first substrate-side contacts; On the other front and rear sides of the cable side housing, they are arranged side by side at the arrangement pitch in the left and right direction at a position shifted in the left and right direction by half of the arrangement pitch with respect to the first cable side contact And a plurality of second cable-side contacts respectively contacting the contacts. The cables are respectively connected to a plurality of first cables connected to first cable connection portions of the plurality of first cable side contacts, and to a second cable connection portion of the plurality of second cable side contacts. The first cable connection portion and the second cable connection portion arranged at different positions in the vertical direction, and the first cable connection portion and the second cable connection The first cable and the second cable connected to the unit are configured to extend in the same direction.

  In the connector device having the above configuration, each of the plurality of first substrate side contacts has a first substrate connection portion connected to the connection portion on the substrate, and the first substrate connection portion is the substrate side housing. Each of the plurality of second substrate contacts has a second substrate connection portion connected to the connection portion on the substrate, and the second substrate connection portion is the substrate. It is preferable to be extended and provided in the front and back other side of a side housing.

  According to the connector device of the present invention, the arrangement pitch with respect to the first substrate side contact and the first cable side contact arranged in parallel at a predetermined arrangement pitch, and the first substrate side contact and the first cable side contact And the second cable side contact arranged side by side at a position shifted by half of the first cable, the first cable is connected to the first cable side contact, and the second cable is connected to the second cable side contact It is configured to be connected. That is, the first substrate side contact, the first cable side contact and the first cable, and the second substrate side contact, the second cable side contact and the second cable are shifted by half of the arrangement pitch. . Therefore, the first substrate side contact and the second substrate side contact can be alternately connected to the wiring formed on the circuit board at a half spacing (wiring pitch) of the arrangement pitch. The arrangement pitch of each of the first cable-side contact and the second cable-side contact can be made twice as wide as the wiring pitch on the circuit board. Therefore, a cable having a thickness of up to about twice the wiring pitch on the circuit board can be used as a cable connected to each of the first cable side contact and the second cable side contact. It is possible to use an inexpensive cable that is thicker than the wiring pitch on the circuit board and has good communication characteristics. Since a cable thicker than the wiring pitch on the circuit board can be used, cable breakage can be reduced in manufacturing. Further, the size (width) of the connector device in the arrangement direction can be reduced to about half the size of the conventional connector device in which the contacts and the cables are arranged in a line in the arrangement direction.
