Abstract

PURPOSE:To enable to mount the title electron part socket on a printed board easily and completely by a method wherein a stopper is provided in such a manner that it can be easily inserted into the hole of a socket lead to be soldered and that it can not pulled out easily due to the stopper with frictional resistance in the draw-out direction. CONSTITUTION:A stopper 7, having the lower side as supporting point, which is cut off in tongue-like form at the upper part, is provided at the midway point located outside a socket main body 1 of the socket lead 6 which is coming out on the lower surface of the socket main body 1. When the socket lead 6 is inserted into the inserting hole of a printed board 4, the stopper 7 can be inserted easily without having much resistance in the crushed shape. After the inserting work has been finished, the stopper is restored to its original position by elasticity, the tongue-shaped tip part is caught on the lower surface of the printed board 4, and the socket can not be drawn out from the inserting hole under this condition. As a matter of course, the socket does not fall off even when it is turned over when a soldering work is performed, and the floating up of the socket can also be prevented even when it is dipped in a solder vessel.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention enables easy VF-replacement when mounted on a semiconductor electronic component such as a transistor or an integrated circuit, or a key component τ printed circuit board such as a circuit module. Contains an electronic component socket V for mounting on.

a.Prior art Figure 1 shows a conventional printed board (tau) which is covered with an electronic component pocket for board A. In the figure, l is the socket body, 2 is the receiving hole into which the iron layer 1 child part glue dowel is inserted, 3 is the receiving hole 2 with one end fixed to a, and the other end of the socket main body l. It is a socket lead pulled out to the bottom side.

In order to install such a socket, insert the socket lead 3 of the socket into the socket lead insertion hole 5 of the printed circuit board 4 to which the connector L is attached, and insert the conductor around the surface of the insertion hole 5 of the printed yellow board 4. It is attached to the printed circuit board 4 by soldering with the pattern.

There are actually two ways to install a socket like this: That is, in the first method, after inserting the socket lead of the socket into the insertion hole 5 of the printed circuit board,
The conductor pattern surface of the printed board A is immersed in a solder bath, and the socket lead 3 and the conductor pattern of the printed circuit board are soldered. The second method is to insert the socket lead 3 into the insertion hole 5rc, turn the printed circuit board 4 over, and solder the socket lead and the conductive pattern using a soldering iron.

However, in conventional sockets, the first
In the case of the above method, the socket leads were pushed up by the surface tension of the molten solder, which caused the socket to float from the printed circuit board. In the second method using a 7tb soldering iron, the printed circuit board is turned upside down! , the socket falls off the printed circuit board. Therefore, in order to prevent this, there was a drawback that the socket had to be fixed to the printed circuit board in advance7. To provide an electronic component socket for a printed circuit board which prevents the socket from floating or falling off and can be easily and reliably mounted on the printed circuit board.

21. Structure of the Invention An aspect of the present invention is that the socket lead that is inserted into the socket lead insertion hole of a printed circuit board and soldered thereto is easy to insert into the insertion hole and is reversed in the direction of extraction. There is a stopper that acts as a stopper and prevents it from being pulled out easily.
An electronic component socket for a printed circuit board is obtained.

E. Examples □ The present invention will be explained by referring to examples. Figure 2 (・)
1 is a perspective view of one embodiment of the invention, and 11 is an enlarged view of the socket lead in the same figure (2
As shown in Figures (a) and (b), the socket lead 6 pulled out to the underside of the socket main body 1 has a tongue piece on the upper side with the lower side as a fulcrum on the way out from the socket main body l. A stopper 7 is provided which is cut out into a shape.

and FIG. 3 are partial cross-sectional views of the inventive socket bullet board shown in FIG. In Figure 3, when inserting the socket lead 6 into the insertion hole of the printed circuit board 4,
The stopper 7 can be easily inserted without much resistance in the direction in which the pusher elbow is retracted as the stopper 7 is inserted. After insertion, the elasticity of the t-stopper 7 restores the socket to the original state, and the tongue-like tip part is stuck to the bottom surface of the bullet board 4. In this state, the socket cannot be easily pulled out from the insertion hole. Can not.

Of course, soldering is work, and the socket will not fall off even if it is turned over, and the socket will not float up even if it is immersed in a solder bath.

FIG. 4 is a partial cross-sectional view of another embodiment of the present invention mounted on a printed circuit board. In the example of FIG. On the other hand, in the case of the unusual socket lead 8, the tongue-like tip of the stopper 9 is provided in a position where it can be caught on the way out of the insertion hole, so it is difficult to mount it. This has the effect that even if the thickness of the printed circuit board to be used varies, it can be accommodated with the same stopper position.

0 Effects of the Invention As mentioned above and 29, in the socket of the present invention, there is a tyc that is pulled out to the bottom side of the socket main body, and there is a hole in the middle of the outside of the socket lead when it is pulled out, so that it cannot be pulled out easily and cannot be inserted. When soldering an insertion socket lead to a conductive pattern on a printed circuit board by providing a stopper that can be easily inserted without resistance, the soldering can be done easily and reliably (regardless of the soldering method). There is no installation required.2
In the embodiment, the upper part of the stopper is bent outward.
Even if you bend it inward, the effect remains the same. Alternatively, it may be half punched in the center of the width instead of on one side.
