In addition, any of the above-mentioned fixing brackets is a fixing bracket dedicated to a surface mount type connector or a DIP type connector, and is not structured to be used for both. There is a problem that it is necessary to separately prepare a corresponding fixing bracket.

Therefore, there is a problem that the area of the actual soldering area can be increased, and the structure of the fixture must be able to cope with both the surface mount type and the DIP type connector.

[0010]

In order to solve the above-mentioned problems, a connector according to the present invention comprises an insulating housing having an opening at an upper portion, and a plurality of electrical connections provided inside the housing for obtaining electrical connections. A connector comprising a connection terminal having an end portion of a contact taken out of the housing and a fixing bracket attached to a bottom of the housing and bent at a right angle for reinforcing and fixing the housing on a substrate,
In the fixing bracket, an upper piece bent at a right angle is fixed to a housing, and a notch is formed in a direction of a free end from a middle of a lower piece to be fixed by soldering to a substrate to increase a soldering area.

The number of cutouts provided in the lower piece is a plurality; the fixing bracket used for the DIP type connector is such that the cutout portion of the lower piece is further moved downward. At right angles.

[0012] By adopting a structure in which the notch is provided on the surface of the fixing metal to be soldered, the creepage area for actual soldering can be increased, and the surface mounting type connector and the DIP type connector can be connected to each other. Since it can be used for both, new equipment such as a mold is not required.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of a surface mount type connector and a DIP type connector according to the present invention will be described with reference to the drawings. The same components as those in the prior art will be described with the same reference numerals.

As shown in FIGS. 1 and 2, the surface mount type connector 10 has a substantially box-shaped insulative housing 20 having an opening at an upper part, and an electrical housing arranged in line with the inside of the housing 20. It is composed of a plurality of contacts 21 for obtaining a proper connection, a plurality of connection terminals 22 having ends of the plurality of contacts 21 taken out of the housing, and a fixture 12D for reinforcing and fixing the housing 20 on the substrate 11. ing.

The fixing bracket 12D comprises an upper piece 13D and a lower piece 14D formed by bending a metal plate member at a right angle. At the upper end of the upper piece 13D, there is provided a press-fit end 23 formed by further bending at a right angle in a direction bent at a right angle. The lower piece 14D is formed to be longer than the upper piece 13D, and has a structure in which a notch 24 is provided in an extending direction from a central position having a predetermined width from a base bent at a right angle. By providing such a notch 24, the lower piece 14D forms tongue pieces 25 and 26 having a forked shape, so that the creeping area in contact with the solder on the substrate 11 can be increased.

The fixing bracket 12D having such a structure
Press-fits the press-fit end 23 into the side wall of the connector 10 and fixes it. When the connector 10 is arranged on the substrate 11 and the connection terminals 22 are soldered, the soldering area of the lower piece 14D of the fixing bracket 12D can be increased, so that the reinforcing strength of the soldering can be improved.

On the other hand, the DIP connector 10A is shown in FIG.
As shown in (A), (B) and (C), a through hole 18 is provided on the substrate 11A, and the fixing fitting 1 is provided in the through hole 18.
The structure is such that the lower piece 14D of 2D is inserted and soldered.

The fixture 12D is the same as that used in the surface mount connector 10 described with reference to FIG.
The tongue pieces 25 and 26 having a forked shape are used by being further bent at a right angle downward. Since the tongue pieces 25 and 26 provided with the notches 24 can be easily bent.

As described above, the same metal fitting 12D can be used for both the surface mount type connector 10 and the DIP type connector 10A. This improves the reinforcing strength and eliminates the need for a new mold, thereby reducing costs.

FIGS. 4A and 4B show a fixture 12E having a structure different from that of the fixture 12D described above. The fixing bracket 12E has a structure in which two notches 24a and 24b are provided in parallel in a free end direction on a lower piece 14E bent at a right angle to the upper piece 13E. 2
The lower piece 14E provided with the notches 24a and 24b is formed of three tongue pieces 27, 28 and 29, and has a so-called trifurcated shape. With such a three-pronged structure, the creepage area for soldering is large, and the reinforcing strength when the connector 10 is arranged and fixed on the substrate 11 can be further improved.

FIG. 5 shows the fixing brackets 12D, 1
2E shows a fixing bracket 12F having a structure different from that of FIG. 2E, and shows a lower piece 14F bent at a right angle to an upper piece 13F.
Has a notched tongue piece 30 leaving one piece at the center position of the tongue. Fixing bracket 12 having such a structure
When the F is mounted on the surface mount type connector 10, it is mounted in the shape shown in FIG.
The tongue piece 30 may be bent at a right angle in the lower direction with reference to the base 31 (the portion indicated by the dotted line).

Incidentally, the fixing brackets 12D, 1
2E and 12F have been described, but without being limited to these, the creeping area that can be soldered can be made large,
In addition, a fixing bracket structure that can be used for both the surface mount connector 10 and the DIP connector 10A may be used.
