Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for a printed circuit board.
For example, the present invention relates to a printed circuit board connector that can be applied to a narrow place where connection of a mating connector is restricted by a front wall or the like.

[0002]

2. Description of the Related Art A printed circuit board connector is provided with a plurality of terminals electrically connected to the printed circuit board and is fixedly arranged on the printed circuit board. Generally, the connector is mounted horizontally or vertically to a mounting surface of the board. FIG. 4 (a), (b)
1 shows an example of a conventional horizontal type printed circuit board connector.
The connector housing 1a is placed laterally with respect to the mounting surface of the substrate 3 in a state where the plurality of terminals 4 protruding from the rear surface of the substrate 3 and bent in an L shape are connected to the electrode forming portions 3a at the ends of the substrate 3. This is a configuration fixed to And in (a),
The printed circuit board connector 1 is attached to an escutcheon 7 of a device or the like in a narrow place where the front wall W is provided close to the mating connector 5 in a state where the mating with the mating connector 5 is performed. Shows the case. (B) shows a case where fitting between the connectors is performed by applying the wiring direction of the electric wire 5a of the mating connector 5 to a position where the wiring 5a is regulated so as to be bent forward of the connector.

[0003]

By the way, when the printed board connector 1 is applied to a place where the installation space is restricted as described above, in FIG. Because of the two stages, the bent part of the mating connector, especially the inner wire, becomes excessively bent and the load increases, so that it is difficult to arrange multiple terminals in multiple stages. It is not suitable for multi-pole connectors. When a plurality of terminals are arranged side by side in a horizontal direction to form a multi-row instead of a multi-stage configuration, the area occupied by the connector housing to be mounted on the substrate is undesirably increased.

When a mating connector is fitted in a state where the wiring direction is restricted and the wire is bent, as shown in FIG. However, there is a problem that it is difficult to insert the connector into the connector, and thus the fitting workability is poor. Further, even in a vertical type (not shown), for example, in a narrow place where the front wall W is provided close to the printed circuit board, a connector for a printed circuit board vertically arranged with respect to the mounting surface of the board is used as a device or the like. Since the connector housing is provided so as to be sandwiched between the front wall W, a multi-pole printed circuit board connector in which the connector housing is enlarged by increasing the number of terminals is used in the case of the horizontal type described above. Like, could not be applied.

[0005] The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a connector for a printed circuit board which realizes space saving and can be applied to a narrow place, and at the same time, can smoothly perform a fitting operation with a mating connector.

[0006]

According to a first aspect of the present invention, there is provided a printed circuit board connector comprising a connector housing having terminals connected to the printed circuit board and being fixed to the printed circuit board. Wherein the connector housing is attached to the mounting surface of the printed circuit board at an elevation angle inclined outward, and the mating connector is fitted obliquely from above.

Since the printed circuit board connector is mounted on the mounting surface of the board with the connector housing inclined, the connector fitting area can be shortened in the connector fitting direction to save space. . Therefore, the present invention can be applied to narrow places where the installation space is limited.

According to a second aspect of the present invention, in the connector for a printed circuit board, the inclination angle of the connector housing is set in accordance with a wiring direction of an electric wire connected to a terminal of a mating connector.

In this printed circuit board connector, since the inclination angle of the connector housing is set in accordance with the wiring direction of the mating connector, the mating connector is moved along the wiring direction of the mating connector and fitted. Therefore, smooth fitting can be performed and fitting workability can be improved.
