Description

[Detailed Description of the Invention] The present invention relates to a method for soldering a metal outlet, and in particular, a method for soldering a metal outlet that can be applied to metal outlets for lead wires of various devices such as computers, communication devices, and control equipment. Regarding.

2. Description of the Related Art Conventionally, in cables for various devices such as computers, communications, and control devices, metal outlets as shown in FIG. 1 have been used at the attachment/detachment portions of a large number of lead wires. This kind of outlet is
There are various forms such as the number of pins and the structure of the pitch connection part, and because they are produced in a wide variety and in small quantities, each piece is made by hand.
We are doing the underwriting. For example, in Fig. 1, 1 is a pin, 2 is a hollow part, 3 is an insulating resin plate, 4 is a part of the connector (connecting part), 5 is a snap ring, 6 is a lead wire, 7 is a bare wire, and 8 is a non-conductor. , 9 is 7'-nda iron, hollow part 2
Corresponding to the depth, remove the vinyl coating of the long lead wire 6, and solder the bare wire 7 and the soldering iron 8 with a soldering iron 9.
After heating and melting the solder 8 to sufficiently penetrate the bare wire 7, the solder 8 is inserted into the cavity 2 and the vicinity thereof is heated to further penetrate and solidify the solder 8. This work is carried out manually one by one. Therefore, the conventional soldering method described above has the following drawbacks.

■ Work efficiency is poor because each point is done one by one.

(2) After inserting the bare m7 into the cavity 2, it is necessary to heat the vicinity thereof until the molten solder penetrates, so the time required is long, and the cumulative time required at each point is enormous.

(2) If the pitch of each point is minute, it is difficult to approach the X71 iron, and even if it is possible to approach, the vinyl portion of the lead wire 6 may be burnt out.

- Since the cavity 2 is shallow, insufficient solder penetration may result in poor conductivity and breakage.

The present invention has been proposed in view of the above circumstances, and the purpose of the invention is to solve the various drawbacks of the above conventional methods and provide a highly efficient and reliable method for soldering metal outlets. There is something to do.

The inventor of the present invention analyzed the reason why the conventional method of soldering a metal outlet requires an enormous amount of time, and found that it takes a long time until the lead wires at each point and the vicinity of the cavity rise to a predetermined temperature. It turned out that the time required was the biggest bottleneck. Therefore, we determined that it would be sufficient to insert all the bare wires into the six cavities in advance and then solder all the wires at the same time.

The present invention has been made based on the above knowledge, and the method of soldering a metal outlet according to the present invention is to use a thin wire covered with an insulating material in a metal outlet having a hollow conductive bottle vertically installed on an insulating plate. The tip of the group conducting wire is a bare wire longer than the length of the hollow conductive pin, and the bare wire is inserted through the hollow conductive pin and protrudes from the tip of the hollow conductive pin. It is characterized in that it is immersed in a molten solder bath to allow solder to permeate therein, and then pulled up from the molten solder bath to cut off its protruding portion, and each probe wire is made to protrude from the tip of each hollow conductive pin. immersed in a molten solder bath, each thin wire group is penetrated with molten solder by capillary action, filling the space between each bare wire and each hollow conductive pin with solder, and soldering all points at the same time. This makes it possible to perform highly efficient and reliable soldering.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

fr Figures 2 to 4 are explanations (2) showing the steps of the method for soldering a metal outlet according to the present invention, in which Figure 2 shows the state of lead wire insertion into the hollow part/through pin, and Figure 3 shows the situation in which all points are soldered at the same time, and Figure 4 shows the situation in which the remaining parts are removed and finished.

In Figures 2 to 4, θ is a hollow conductive pin, 02 is a hollow part, 03 is an insulating resin plate, 04 is a part of the connector (connecting part), 05 is a snap ring, 06 is a lead wire, and o7 is a bare wire. , o8 is the protruding part, 08 a 113 is the line penetrated by the wire, 09 is the molten solder, 010 is the melting tank, 011 is the heater, ! is the length of the bare wire and h is the taste of the bottle.

A method according to an embodiment of the present invention will be described.

(1) All required leads, from the tip of v06 (A>h)
If necessary, twist the thin wire group of bare wires 07 to facilitate insertion and apply paste.

(2) Insert each bare wire 07 into the through-hole conductive pin θ at a predetermined position, and make it protrude from the tip of the bottle to form the protruding part 08.
make.

(3) The solder 09 is melted in advance in the bath θ10 in which the heater 011 is attached. By immersing all the tips of the protruding parts 08 of the outlet into which the bare wires 07 are inserted in fJ (2) for a predetermined length into the melting surface of the solder θ9 and leaving them for a predetermined time, the temperature of the protruding parts 08 and the hollow conductive pins 01 can be lowered. As it rises, the molten solder 09 rises through the capillary gap of the f1 line group to the opposite end face of the conductive bottle 01 as shown by the arrow, and melts to 4 oz.

Karatorishi is out. If the paste is not applied in (1) above, it will be more efficient if the tip of the protrusion 08 is immersed in the molten paste bath in the same manner as in (3) before soldering.

(4) After that, the line 08EL shown in FIG. 4 where the solder penetrated is cut out to complete the process.

As described above, according to the present invention, the following excellent effects can be achieved.

■ By using a through-hole conductor, it is easy to insert and hold the lead wire.

(2) By providing the protrusion 08 of the bare wire θ7 at the tip of the pin, 1 molten solder (or molten paste) can penetrate through the capillary 4411 phenomenon of the thin wire group.

■ Jun Tanikata 07'J2r: All the hollow conductive pins 01 are inserted and soldered at once (simultaneously) in the RC state, so the soldering (total heating time) can be significantly shortened.

■ Since soldering is performed from the tip of the pin, soldering can be performed even if the pitch of the bin arrangement on the back is extremely small.
The vinyl of lead ff1JO6 will not be burned out.

■ Capillarity progresses as the molten powder permeates and fills the gap between the J411 wire groups, increasing the heat transfer area, resulting in a faster temperature rise and therefore faster penetration, making it difficult to heat for a long time. Therefore, the vinyl of the insulating resin plate 03 and the lead wire 06 will not be burned out.

■ After soldering, the gap between the hollow conductive pin and the bare wire is filled sequentially from below, so the heated and expanded air is released upwards, resulting in a solid pin with fewer defects, resulting in highly reliable soldering and strength. A high pin can be obtained.
