Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a mounting method for mounting a socket on a printed circuit board in an electronic device.

(b) Prior Art Conventionally, sockets as shown in FIGS. 2 and 3 (hereinafter described as a first conventional example) are often used to take out circuit signals from a printed circuit board to the outside. When a plurality of printed circuit boards that can be soldered only on the back side are stacked together and an electrical connection is made between each board, the socket glue that constitutes the connection terminal is used as shown in the first conventional example. It becomes necessary to take out the wire from the back side of the printed circuit board, and in this point, the first
The conventional example is valid. However, in the first conventional example, it is necessary to insert all the terminals of the socket into the through-poles of the board, which poses a risk of incorrect insertion and is extremely problematic in terms of workability. As an example of solving the above drawbacks,
-15094 (hereinafter described as a second conventional example). According to the second conventional example, only the short terminal of the socket having the locking part is inserted into the through hole of the board and soldered, and the socket is connected to the board by engaging and holding one end of the board with the locking part. This reduces the work required to insert the socket terminal into the through-hole of the board by half, improving work efficiency, but it has the disadvantage that the shorter terminal of the socket must be manually soldered.

(c) Purpose of the Invention The present invention has been made in view of the above-mentioned points, and an object of the present invention is to propose a socket mounting method that allows the socket to be dipped in an automatic solder bath.

(D) Structure of the Invention The present invention includes a hook engaging through hole, a plurality of linearly arranged lead wire insertion holes, and a plurality of cuts placed at the end in parallel with the lead wire insertion holes. In the first step, insert the tip of the long lead wire of the socket into the lead wire insertion hole from the front side of the board having the notch, and then insert the tip of the lead wire from the back side of the board. a second step of dipping the lead wire in an automatic solder tank; and a second step of bending the lead wire through the notch and engaging a hook integrally formed on the socket holder with the hook engagement hole from the back side of the board. This socket mounting method consists of three steps.

(e) Examples An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a socket and a printed circuit board according to the present invention, FIG. 4 is a perspective view of the socket mounted on the printed circuit board, and FIG. 5 is a sectional view of the main parts thereof. The socket (1) is formed by fixing L-shaped metal lead wires (3) (3) (3) to a resin molded socket holder (2). Hooks (2a) (2a) are integrally molded at both ends of the socket holder (2), and a first hook (2a) is integrally formed on one side.
A connector insertion opening (2c) having a notch (2b) is provided. The first notch (2b) is provided to prevent incorrect insertion of the connector (8) regardless of the number of terminals in the socket (1). Connector connection terminal of the lead wire (3) (3) (3) <3
a)<3a)(3a) On the side other than (3a), there is a tapered tip (3c) (lc) (3c) and further the tip (
3c) (3c') (3c> and the socket boulder (2
) has a narrow part (3b) in the middle that is easy to bend.
)(3b)(3b) are provided. Printed board(

However, the size of the lead wire insertion opening (6) is such that only the tip end (3c) (3c>(3c)) can be inserted.

Next, a method of attaching the socket (1) to the printed circuit board (4>) will be explained.

First, the tip comb portion (3c>'(3c) (3c)) is inserted into the lead wire insertion port (6) from the surface side of the printed circuit board (4) (first step). Next, dip the back side in an automatic soldering tank (second step).Furthermore, as shown in Fig. 1, fold it in turn at each bending position of A-A', B-B', and c-c'. , the narrow part (3b) (3b) (3
b) into the second notches (7), (7)..., positioning is performed, and finally the hook (2a)
(2a) is engaged with the hook engaging through holes (5) (3rd step), thereby completing the attachment of the socket (1) to the printed circuit board (4).

(F) Effects of the Invention As described above, according to the present invention, when attaching a socket to a printed circuit board, it is now possible to perform dipping in an automatic solder tank instead of the conventional manual soldering process, which improves work efficiency. It is extremely effective in terms of
