[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a flat electrical connector incorporated in a connector mounted on a printed circuit board, and more particularly, to a base formed by a shear surface stamped from sheet metal material. The present invention relates to a flat electric connector in which a connection portion and a contact portion having a contact pressure application arm are integrally formed.

[0002]

2. Description of the Related Art For example, a multi-pole connector incorporating a flat female electrical connector whose outer shape is formed by a shearing surface obtained by stamping a sheet metal material, such as a fork-type contact, has a connector pitch. Because it can easily be made smaller,
Various types are known, and two types of means for fixing such an electric connector to a connector housing are shown in FIGS. 2 and 3. In order to simplify the drawing and facilitate comparison with the embodiments of the present invention described below, the housing of the connector shown in FIGS. 2 and 3 is not directly related to the fixing of the connector. Is omitted.

The electrical connector 2 of the female connector shown in FIG.
The base 21 is provided with a locking projection 24.
When the connector 20 is assembled into the housing 23 of the connector, the base 21 of the connector 20 is pressed into the slot 22 of the housing 23 and the locking projection 24 is inserted into the wall 2 of the housing.
The connector 20 is fixed to the housing 23 by biting into the connectors 5 and 26. Reference numeral 29 denotes a connection portion to be soldered to a conductor of the printed circuit board.

The connector 30 of the female connector shown in FIG. 3 has a fixed leg 32 facing a contact portion 31 having a curved arm.
Have Connector 30 in connector housing 33
When the connector 30 is assembled, the connector 30 is fixed to the housing 33 by pressing the fixing leg 32 of the connector 30 into the slot 35 of the housing 33 and making the locking projections 34 bite into the wall portions 37 and 38 of the housing 33. doing. Reference numeral 39 is a connection that is soldered to a conductor on a printed circuit board.

In the conventional connector as described above, in order to reduce the size of the connector, it is required to reduce the size of each part of the connector and the size of the housing. However, when the wall thickness of the housing wall (25, 26 or 37, 38) is reduced, the locking projection (24, 3
4) causes bulging, cracking, and the like on the wall of the housing, and if these defects occur, the fixing force of the connector is reduced, which causes a problem of poor connection of the connector. Therefore, if the material of the housing is fixed, there is a certain limit in reducing the thickness of the wall of the housing. The use of advanced materials to increase the strength of the housing not only increases the material cost, but also increases the housing,
There is a problem that the manufacturing technology of the connector needs to be more advanced, and the manufacturing cost becomes higher.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electrical connector in which a connector using a flat connector can be miniaturized.

[0007]

SUMMARY OF THE INVENTION According to the present invention, in order to avoid the above-mentioned problems which occur in order to achieve the miniaturization of the connector, when the connector is pressed into the slot of the housing, the groove of the connector is slotted in the housing. The connector is fixed to the housing by providing a structure for sandwiching the inner projection.

1 is a perspective view of a flat electric connector 10 according to the present invention, and FIG. 1 is a perspective view of a flat electric connector 10 according to the present invention. FIG. 2 shows a perspective view of the connector 10 incorporated in FIG. In the upper figure, in order to avoid unnecessary complication of the drawing, the figure shown as the housing 101 of the connector shows only a part necessary for fixing the connector 10, and various other parts functioning as a connector are shown. Is omitted. The double-headed arrows A indicate the respective directions in which the male connector is inserted and removed.

As can be understood from the lower view of FIG. 1, the connector 10 having the connection portion 14, the base portion 11, and the contact portion 13 having the contact pressure applying arm 12 is formed integrally by punching a sheet metal material. I have. Accordingly, the housing wall 10
The electrical connection with the conductor of a male connector (not shown), guided by 2 and inserted in the direction of arrow A, is made by means of the shear surface of the contact 13. By soldering to a conductor on a printed circuit board (not shown), the connection 14 for electrically connecting the connector 10 to the conductor on the circuit board is shown as a solder tail type. However, it can be any other structure, such as a press-fit type.

In accordance with the present invention, the base 11 of the connector 10 is provided with a groove 15 having a pair of locking projections 16,17.

The housing 101 shown in FIG. 1 is shown as including a plurality of slots 18 for inserting the base 11 of the connector. Each of the slots 18 has a width close to the thickness of the connector 10 and a depth for substantially accommodating the base 11, and a connector fixing projection 19 is provided at the bottom of the slot 18. When assembling the connector by inserting the entire connector 10 having the contact pressure applying arm 12 and the base 11 into the housing 101 in the direction of arrow B, that is, inserting the base 11 of the connector into the slot 18 of the housing. At this time, the groove 15 of the connector base 11 is pressed into the connector fixing projection 19 of the housing, and the locking projections 16 and 17 are cut into the fixing projection 19, so that the connector 10 is inserted into the housing 101. Fix it. in this way,
Since the connector of the present invention uses the fixing means for compressing and fixing the plastic material, the housing does not bulge or crack unlike the conventional fixing means.

There are a wide variety of connectors incorporating connectors having a shear surface as a contact portion. Accordingly, the connectors and housings have various forms, and various connectors and housings are provided within the technical scope of the present invention. It is necessary to call attention to the existence of this form. Since the connector of FIG. 1 is shown as a receptacle type connector, a female connector having a contact projection of a contact portion provided in the direction of the wall surface 102 of the housing,
Although the housing is shown, for example, in order to obtain a plug-type connector, a connector provided with a contact projection of the contact portion 13 on the opposite side to the wall surface 102 and a housing which is compatible with the connector are provided by the present invention. It is obvious that a person skilled in the art can apply satisfactorily, so that no further explanation will be given.

[0013]

In contrast to the conventional fixing means of the type in which the two walls of the housing are pushed open, the fixing means of the connector of the present invention does not cause blistering or cracking of the housing and furthermore, the entire connector. Can be reduced in thickness.
