Abstract

PROBLEM TO BE SOLVED: To commonly use a counterpart connector for a printed circuit board. SOLUTION: A connecting portion 12a to be soldered to a printed circuit 13b at the obverse of a substrate 13 is formed at one end of a terminal metal fitting 12; in the meantime, a plate-like tab 12b is formed at the other end of the metal fitting 12 and is projected inside of a case body 11, thereby obtaining a connector 11a for a printed circuit board. The tabs 12b are juxtaposed in contact along at least one inner wall 11a of the case body 11 parallel to a contact surface. The tab 12b can be connected with an elastic contact piece 20c of a connector for an FPC serving as a counterpart connector.

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, and more particularly, to a connector for a flexible printed circuit (FPC) as a mating connector connected to the connector.

[0002]

2. Description of the Related Art Electrical components for automobiles include those having a printed circuit board and those having an FPC depending on the grade of the vehicle, even if they are arranged at the same location. The wire harnesses connected to the electrical components are connected to terminals by attaching mating connectors respectively corresponding to a printed circuit board and an FPC.

[0005] That is, as shown in FIG. 5 (A), in the printed circuit board 1, a printed circuit board connector 2 for fitting a mating connector 3 is attached to one end of a terminal fitting 4 on the back surface of the printed circuit board 1. A connecting portion 4a to be soldered to the printed circuit 1a is formed, and a tab 4b having a plate shape is formed at the other end, and the tab 4b is provided to protrude from the center of the case body 2a. The mating connector 3 connected to the board connector 2 has a general female connector structure in which a female terminal 3a is housed in a cavity, and is fitted into the case body 2a of the board connector 2. As a result, the tab 4b is inserted and contacted into the female terminal 3a of the mating connector 3 (for example, Japanese Utility Model Laid-Open No. 5-75971).

On the other hand, in the FPC 5, an FPC case body 6 for fitting a mating connector 7 is shown in FIG.
As shown in (B), the terminal of the FPC 5 arranged along the base member 5a is arranged in a folded shape along the inner wall 6a of the FPC case body 6. The mating connector 7 has a general FPC connector structure in which an elastic contact piece 7a protrudes from one surface in a direction orthogonal to the fitting direction, and is fitted into the FPC case body 6. By doing so, the elastic contact piece 7a is brought into contact with the conductor on the surface of the FPC 5 (for example, actual open flat 7-1838).
No. 5).

[0005]

As described above, the types of mating connectors to be connected are different between the case where the device is a printed circuit board and the case where the device is an FPC. It is necessary to prepare a provided wire harness, which complicates the manufacturing process and increases the cost.

[0006] The present invention has been made in view of the above-described problems, and enables the FPC connector to be shared and connected as a mating connector, as in the case of the FPC specification, even if the device is a printed circuit board specification. It is an object to simplify a manufacturing process of a wire harness and reduce costs.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a connecting portion to be soldered to a printed circuit on a back surface of a substrate is formed at one end of a terminal fitting, and the other end is formed. In a printed circuit board connector having a tab-shaped tab formed thereon and projecting the tab inside the case body, the tab is arranged in a contact state along at least one inner wall of the case body parallel to the contact surface. There is provided a printed circuit board connector characterized by being arranged.

[0008] With this configuration, the contact surface of the tab of the printed circuit board connector can correspond to the contact position with the elastic contact piece of the FPC connector. That is, an FPC connector having an elastic contact piece protruding from one surface in a direction orthogonal to the fitting direction is fitted into the case body of the printed circuit board connector, thereby printing the elastic contact piece of the FPC connector. The tab of the board connector can be contacted. Therefore, as a connection member of the wire harness to the electrical equipment of the printed circuit board specification, the F
The PC connector can be shared.

The tabs arranged in parallel in the case body include:
The case may be arranged in contact with each other along both opposing inner walls of the case body parallel to the contact surface of the tab. In this case, it is possible to cope with a case where a two-stage FPC connector having elastic contact pieces protruding from both sides is connected as a mating connector.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show a first embodiment of a printed circuit board connector 10. The printed circuit board connector 10 includes a case body 11 in which a mating connector 20 attached to a terminal of a wire harness is fitted. Body 1
It is composed of a plurality of terminal fittings 12 projecting in parallel into one.

The terminal fitting 12 is formed by bending a metal plate material, and has a printed circuit 1 printed on the back surface of the substrate 13 at one end through a mounting hole 13 a of the substrate 13.
A connection portion 12a for soldering to 3b is formed. On the other hand, the other end of the terminal fitting 12 has a plate-like tab 1.
2b is formed, and the tabs 12b are protruded toward the connection port 11a of the case body 11 by press-fitting or molding, and are arranged in parallel in a contact state along the inner wall 12c on the lower surface parallel to the contact surface of the tab 12b. (Figure 2).

As shown in FIG. 3, the mating connector 20 connected to the printed board connector 10 is a general FPC connector, and corresponds to the arrangement interval of the terminal fittings 12 of the printed board connector 10. Thus, a plurality of contacts 20b are inserted into the housing 20a.
The contact 20b has an elastic contact piece 20c protruding in a mountain shape on one surface in a direction orthogonal to the fitting direction.

To connect the mating connector 20 attached to the terminal of the wire harness to the printed board connector 10 having the above configuration, as shown in FIG. 3, the housing 20a is connected to the case body of the printed board connector 10. 11 and fixed by a lock mechanism (not shown). At this time, the housing 20a of the mating connector 20
The elastic contact piece 20c exposed from the lower surface of the case body 11 is elastically bent and comes into contact with the tab 12b on the inner wall 12c of the case body 11 with an appropriate contact pressure. As described above, since the mating connector 20 composed of the FPC connector can be connected to the printed board connector 10, the wire harness can be used regardless of whether the specification of the device is FPC or printed board. A common connector can be used as the side connector.

FIG. 4 shows a second embodiment, in which the board connector 30 is arranged with the tabs 32b of the terminal fittings 32 along the opposite surfaces of the inner wall 31a of the case body 31, respectively. In this example, the connection port 31a of the case body 31 is disposed downward toward the opening 33c formed in the substrate 33, and the connection portions 32a of the terminal fittings 32 are opposed to the outer surface of the case body 31 at both sides thereof. It is inserted into a mounting hole 33a which is a soldering portion of the substrate 33. In the second embodiment, the mating connector 40 to be connected to the board connector 30 corresponds to one in which elastic contact pieces 40c are arranged on both surfaces of a housing 40a in a direction orthogonal to the fitting direction.

[0015]

As is apparent from the above description, according to the printed circuit board connector of the present invention, the FPC can be performed without using a dedicated connector for the printed circuit board as a mating connector attached to the terminal of the wire harness. Connectors can be fitted and connected as they are. Therefore, regardless of whether the device side is a printed circuit board or FPC specification,
A common FPC connector can be used as the mating connector, and the wire harness manufacturing process can be simplified and the cost can be reduced.
