Description

  The present invention relates to a composite connection device in which a cylindrical plug portion and a plate-like connector portion used for transmission and reception of audio signals and various control signals in various portable devices are integrally coupled via a housing.

  When this type of composite connection device is used in, for example, a small audio device, in many cases, a cylindrical plug portion is used for sending and receiving audio signals, and a plate-like connector portion is used for various control signals, for example, Used to send and receive control signals for playback, stop, and other operations.

  Such composite connection devices are similarly miniaturized and thinned as the mobile devices to be applied are becoming more multifunctional, smaller and thinner, and multipolarized. Terminals that are connecting portions have also been miniaturized and multipolarized, and as a result, the pitch of terminal rows has been narrowed, and direct connection by soldering of lead wires to individual terminals has become difficult.

  More specifically, the electrodes of the plate-like connector part are arranged in parallel with each other at almost equal intervals on both surfaces of the main body, and as the number of electrodes increases, naturally the pitch becomes narrower and the terminal side is the same. It must be narrow. In the current product, the pitch between terminals is about 0.9 mm. Therefore, it is extremely difficult to connect the lead wire to such a narrow pitch terminal by soldering.

Regarding a similar connector, “in a connector including a plurality of contacts arranged in parallel in the pitch direction and an insulator for holding and fixing the contacts,
The contact has a contact portion to be connected to the mating connector, a holding portion to be held by the insulator, and a terminal portion to be connected to the cable.
The terminal portion includes a connection portion to which the cable is soldered, and is formed to protrude from the insulator in the axial direction of the contact,
A "connector in which the connecting portion is formed obliquely in the contact pitch direction" (Patent Document 1) has been proposed.

  The connector of this Patent Document 1 is configured with the terminal portion as described above, thereby avoiding interference with adjacent contacts at the time of assembly and matching the impedance of the connector requiring high-speed transmission. It is said that a space where soldering is possible is secured while aiming for.

  However, such a configuration of the terminal portion is effective for that of narrow pitch contacts arranged in two rows, even if it is effective for that of contacts arranged in a row even at a narrow pitch. I don't think. If this is adopted for each of the terminal portions for the two rows of contacts, there seems to be a problem that the thickness increases as a whole.

JP 2004-158288 A

  The present invention allows connection by indirect lead wire soldering to each terminal while maintaining a narrow pitch state of the terminal portion of the connector portion configured with multiple poles and a narrow pitch while avoiding an increase in size.

When it is inserted between the plate members, it is arranged at the part where the individual terminals on the side facing the terminal row come into contact.

4 of the present invention, in the composite connection device of 1, 2, or 3 of the present invention, a base holding portion for holding the base portion of the terminal row is configured at a portion of the housing where the terminal row protrudes,

As shown in the figure, a counter plate (opposite plate member) 15b is protruded from the housing 3 in parallel with them. The counter plate 15b protrudes slightly wider and slightly longer than the rows of the terminals 15a, 15a... As shown in FIG. Further, the distance between the counter plate 15b and the terminals 15a, 15a,... Corresponds to the thickness of the connection board 16, and the connection board 16 can be inserted without loosening between them.

  The base portions of the terminals 15a, 15a... And the counter plate 15b constituting the terminal portion 15 are supported by a base holding portion 15c as shown in FIGS. As shown in the figure, the base holding portion 15c holds the corresponding portion of the housing 3 so as to surround and hold the bases of the terminals 15a, 15a,... And the counter plate 15b, and the terminals 15a, 15a,. It is configured to bulge in the protruding direction.

  Further, as shown in FIG. 5, the base holding portion 15c is a portion facing each other and the outer layer terminal 4c of the terminal portion 4 of the plug portion 1 similarly to the base holding portion 5b of the first embodiment. The positioning space 17 is defined as a space between the terminals 15a, 15a,... Of the connection substrate 16 and the counter plate 15b, as will be described later. ing.

  As shown in FIGS. 5 and 6, the connection board 16 is basically rectangular, and includes a positioning protrusion 16 b extending on one side end of the front end side 16 a in a direction intersecting the front end side 16 a, Both ends of the rear end side 16c parallel to the front end side 16a are provided with large and small chamfers 16d and 16e to avoid unnecessary enlargement of the connection substrate 16.
