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 (hereinafter referred to as a "printed board") such as an electronic control unit mounted on an automobile.

[0002]

2. Description of the Related Art For example, signal wirings of a large number of switches provided in an automobile are connected to a joint box having a branch circuit. In the electronic unit mounted on this joint box, a vertical type connector for inputting and outputting signals from the joint box is mounted on a printed circuit board, and the bus bar of the joint box is electrically connected to the connector via this connector. You have a connection. This vertical type connector is fixed to a printed board with screws and its terminals are soldered.

As shown in FIG. 5, a connector in an electronic unit mounted on such an automobile has a connector housing 2 as shown in FIG.
A boss portion 4a having a screw insertion hole 4 is provided on each of the fixing portions 3 and 3 protruding from both sides of the printed circuit board. However, screw fastening is usually required at two locations per connector. When a plurality of connectors are used, screw fastening locations are required twice as many as the number of connectors. For this reason, there has been a problem that a mounting space increases and a space for screw tightening and processing man-hours also increase.

[0004] Although there is a connector in which dedicated terminals are combined to make effective use of space, there is a problem that versatility is poor.

[0005]

Conventionally, in this type of printed circuit board, connectors are selectively used for high power and low power. In this case, since each connector requires a mounting area, the connector on the board is required. The space occupancy rate is increased, and not only the space for other components and wiring is reduced, but also the space for the connector itself is often restricted.

Further, a connector in which different dedicated terminals are combined is often used for each model, but in this case, a different connector is required for each model, and the number of connectors mounted on a board is also increased. As described above, when the number of connectors increases, not only the space required for mounting the connectors increases, but also the man-hour for screwing increases.

Accordingly, the present invention provides a connector that requires a small number of screws, requires a small number of mounting steps, and saves mounting space when a plurality of connectors are mounted on a board. It is an issue.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a fixing portion having a through hole is protruded on both sides of a connector housing, and a screw is inserted through the through hole of the fixing portion. In a printed circuit board connector to be mounted on a printed circuit board, a lower plate portion extending toward the front side of the connector housing in parallel with a plate surface of the printed circuit board at a lower end position of the connector housing, and a thickness of the lower plate portion. A shape having an upper plate portion extending to the back side of the connector housing parallel to the plate surface of the printed circuit board at a position above the lower plate portion by a considerable amount, and the upper and lower plate portions are respectively provided in the vertical direction. When a plurality of connectors are arranged facing each other on a printed circuit board, the upper plate part of one fixed part and the lower plate part of the other fixed part of the adjacent connector housing overlap vertically. It, through holes provided in each to meet, is characterized by being configured the fixing unit.

According to the present invention, when a plurality of connectors are mounted on one board, the connectors are arranged side by side, and the other connector is placed on the lower plate of the fixing portion of one of the adjacent connectors. With the upper plate part of the connector fixing part overlapped so that the through holes match each other, a common screw can be inserted into these through holes and tightened, so two screws can be fixed with one screw The parts can be tightened and fixed at the same time. For this reason, even if the number of connectors increases, the number of screws and man-hours required for tightening do not increase so much.

[0010] Further, since the opposing fixing portions of the two adjacent connectors are overlapped and fixed, the mounting space can be saved by the overlapping area.

[0011] In the connector of the present invention, a cylindrical engaging portion protruding upward or downward may be provided at the through-hole forming portion of the lower plate portion or the upper plate portion of the fixing portion. With this arrangement, when the connectors are arranged and the upper plate portion of the fixing portion of the other connector is superimposed on the lower plate portion of the fixing portion of one connector, the upper portion of the upper or lower plate portion is overlapped at the overlapping portion. The engaging portion provided at the through-hole forming portion engages with the through-hole of the other plate portion to position both of them, thereby simplifying the fastening operation with screws.

When the connector of the present invention is mounted alone on a printed circuit board, a screw is inserted into a through hole in either the lower plate portion or the upper plate portion (preferably, the lower plate portion) in the same manner as a normal connector. It only has to be inserted and tightened.
