Abstract

PURPOSE:To surely avoid a situation where a contact fitting is subjected to high load. CONSTITUTION:Wing members 30 and 30 made of sheet metals having bottom surface sections 35 which are soldered so as to be fixed to a mounted substrate, are installed two by two while being mutually separated onto support projected sections 15 and 16 which are formed at both side end sections of a main body section 10. By this constitution, even a space between these two wing sections 30 and 30 can be soldered, thereby the soldering area (Sx+Sy) of each wing member to the substrate can be made large as compared with that of the support projected section having a single wing section, as a result, solder peel strength can thereby be increased.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connector which is surface-mounted on a wiring board, and more particularly to a board called a wing member at both ends in order to reduce a load on a contact metal fitting to be soldered to the board. The present invention relates to the one to which a metal fitting which is soldered and fixed to is attached.

2. Description of the Related Art FIG. 4 (overall view) and FIG. 5 show a conventional example of an electric connector for an FPC of this type. The electrical connector 5 of this example includes a predetermined number of contact metal fittings 60 bent in an approximately 7 shape or an inverted U shape, and the contact metal fittings 60.
A main body 50 is formed by arranging a predetermined number of slit-shaped insertion portions 52, which are inserted in the front-rear direction, side by side in a state of facing each other.

The contact fitting 60 includes the main body 5
6 is inserted from the upper surface opening 53 into the FPC 70 as shown in FIG. 6, and is a substantially V-shaped contact piece portion 62 which is brought into contact with the terminal portions 72 formed on both surfaces of the FPC 70, and a straight line continuous to the contact piece portion 62. It is composed of a shape portion 64 and a bent terminal portion 66 for surface mounting, which is bent from the linear portion 64 in the direction opposite to the contact piece portion 62 by about 90 degrees.

In the contact metal fitting 60, the contact metal fitting 60 in which the bent terminal portion 66 is not bent is pushed from the lower surface side of the insertion portion 52 with the contact piece portion 62 inside (center), By bending the terminal portion 66 in the direction opposite to the contact piece portion 62 by about 90 degrees, the bent terminal portion 66 becomes flush with the lower surface of the main body portion 50, and the electric connector 5 is placed on the wiring board 40. The bent terminal portion 66 comes into contact with the wiring pattern, and they are connected and fixed by soldering.

And, in this electric connector 5,
As shown in FIGS. 5 and 7, in order to reduce the load on the contact metal fitting 60 soldered to the substrate 40,
Support protrusions 55 and 56 that form both end portions of the main body 50
A sheet metal wing member 80 soldered and fixed to the substrate 40 is attached to the. Wing member 8
Reference numeral 0 denotes an L-shape having a vertical side portion inserted into the support convex portions 55 and 56 from the lower surface side and a bottom surface portion 85 abutting against the substrate 40, and the bottom surface portion 85 of the main body portion 50. A portion Sz protruding outward from the side end and having a grid pattern in FIG. 7 is a portion to be soldered (soldering area).

[0006]

In the conventional electrical connector 5 as described above, the wing member 80 (bottom surface of the wing member 80) is used.
However, since the soldering area (Sz) cannot be so large for a large amount, the fixing strength (solder peeling strength) by soldering may be insufficient, and the wing member 80 may float from the substrate due to an external force. There is a possibility that a large load is applied to the contact fitting 60, which causes a problem such that it is removed from the wiring pattern.

In view of such a point, the present invention can increase the soldering area of the wing member to the substrate, increase the solder peeling strength, and cause a situation where a large load is applied to the contact fitting. It is an object to provide a hardened electrical connector.

[0008]

In order to achieve the above object, one of the electrical connectors according to the present invention comprises a predetermined number of contact metal fittings and a slit-shaped insertion portion into which the contact metal fittings are inserted. A main body part arranged side by side, and two wing members made of sheet metal, each having two bottom parts to be soldered to a mounting board, are provided at both left and right end parts of the main body part so as to be separated from each other. It is characterized in that it is attached in a fixed state.

Further, another one of the electrical connectors of the present invention is provided with a predetermined number of contact fittings and a main body section in which slit-like insertion portions into which the contact fittings are inserted are arranged in parallel. A wing member having a bottom portion to be soldered to a mounting board divided into two and a gap formed therebetween is attached to both left and right end portions of the main body portion.

[0010]

In the electric connector according to the present invention having the above-mentioned structure, the two wing members are attached to the respective side end portions of the main body in a state of being separated from each other. Soldering can also be performed on the portion between the individual wing members, so that the soldering area of the wing member to the board, especially the longitudinal direction of the connector ( The soldering area in the lateral direction can be increased (doubled), and as a result, the solder peel strength can be increased, and a situation in which a large load is applied to the contact fitting can be reliably avoided.

Also, by attaching a single wing member having a bottom portion to be soldered to a mounting substrate divided into two and a gap formed between them, to each side end portion of the main body portion. Since the soldering area can be set to be as large as that described above, also in this case, substantially the same operational effects as those described above can be obtained.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of an electric connector according to the present invention, and the electric connector 1 of the illustrated example is similar to the conventional electric connector 5 shown in FIGS.
A predetermined number of contact metal fittings 20 bent in an approximately 7-shape or an inverted U-shape, and a slit-shaped insertion portion 12 into which the contact metal fitting 20 is inserted are opposed to each other in the left-right direction, and are arranged in a predetermined number in front and rear. The main body 10 is provided.

Then, in this electric connector 1,
In order to reduce the load on the contact fittings 20 to be soldered to the board, two pieces are provided on each of the support protrusions 15 and 16 forming the both end portions of the main body section 10, and the mounting board (4
The wing members 30 made of sheet metal having the bottom portion 35 soldered and fixed to 0) are attached in a state of being separated from each other.

That is, the supporting convex portion 1 of the main body portion 10
5 and 16, as shown in FIGS.
Two rectangular slit-shaped fixed insertion portions 17, 17 are formed laterally and at regular intervals, and each of the fixed insertion portions 17, 17 has a fixed insertion portion 17, 17 as shown in FIG.
A vertical side portion of an L-shaped wing member 30 including a vertical side portion 31, locking protrusions 33, 33 projecting from both sides of the vertical side portion 31, and a bottom surface portion 35 bent at a right angle from the vertical side portion 31. 31 is inserted and fixed.

In this case, the bottom surface portion 35 of the two wing members 30, 30 attached to one end of the main body portion 10
As shown in detail in FIG. 3, the protrusions outwardly protrude from the side end of the main body portion 10, and the supporting convex portions 15, 1 are interposed therebetween.
The central projections 18 projecting from the projections 6 are sandwiched between the central projections 18 and the central projections 18 and are spaced apart from each other by a predetermined distance.

In this case, the bottom surface portions 35, 35 of the wing members 30, 30 are located on substantially the same plane as the lowermost end surface of the main body portion 10 and the terminal portion of the contact fitting 20, and in FIG. S with a pattern
Part where x and Sy are soldered (soldering area)
To be

In the electrical connector 1 of the present embodiment configured as described above, the two wing members 30, 30 are attached to the respective side end portions of the main body portion 10 in a state of being separated from each other. So there are two wing members 3
Soldering can also be performed on the part between 0 and 30,
Therefore, the soldering area (Sx + Sy) of the wing member to the substrate, especially the soldering area in the length direction (lateral direction) of the connector 1 is large (about twice as large as that of the one having only one wing member). As a result, the solder peel strength can be increased, and a situation in which a large load is applied to the contact fitting 20 can be reliably avoided.

In the above example, the two wing members are attached to the respective side end portions of the main body portion 10 in a state of being separated from each other, but instead of that, the respective side end portions of the main body portion are attached. Even if you attach a single wing member whose bottom part to be soldered to the mounting board is divided into two parts and a gap is formed between them, the soldering area should be as large as that described above. Since it is possible to obtain the same effect as described above.

[0019]

As can be understood from the above description, the electric connector according to the present invention can increase the soldering area of the wing member to the substrate, so that the solder peeling strength can be increased and the contact metal fitting can be subjected to a large load. This has the effect of reliably avoiding a situation in which the
