Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the connection of conductor portions of conductors used in small and lightweight equipment, and more particularly to a splice pipe capable of deforming the connection portion of the conductor portion to an arbitrary shape. The present invention relates to a method for connecting conductors using a splice pipe.

2. Description of the Related Art Conventionally, when connecting conductors of conductors in equipment mounted on an artificial satellite, a thin metal pipe having a solder hole at the center is silver-plated, and both sides of this metal pipe are plated. Insert the stranded wires, etc., which are the conductors of the conductors pre-soldered from the above, and bring them into contact, and supply the solder while heating the thread solder through the solder holes to fix the conductors and metal pipes A splicing pipe connection method has been adopted in which the connection portion is covered with the heat-shrinkable tube and contracted (see FIG. 4).

[0003]

However, in this conventional method, although the conductor itself such as a stranded wire can be surely and firmly connected, since the metal pipe itself is straight, it can be used in an artificial satellite or the like. The mounting position in was also limited to the straight line part. In addition, the heat-shrinkable tube had to overlap with the metal pipe to ensure insulation, and its length had to be larger than that of the metal pipe. Therefore, it was necessary to secure a linear space above a certain level for mounting.

By the way, in recent years, in artificial satellites and the like, semiconductors and the like more suitable for the environment encountered are being actively developed. As a result, semiconductors have become smaller and more dense, and the number of semiconductor components used has dramatically increased, while the housing itself that houses these circuit components has also rapidly become smaller. For this reason, the connecting parts of the respective parts also become complicated and large, and there has been a strong demand for space saving in the housing, particularly effective utilization of the corner parts having a relatively large space.

However, the conventional metal pipe connection method, which requires a large linear space, cannot be mounted on these corners, and is adapted to the housings of recent artificial satellites that are becoming smaller and more complicated. There was a problem that I could not do it. In this case, it may be possible to design and manufacture a metal pipe that matches the shape of the corners to be mounted, etc., but this complicates the structure and requires versatility for each mounting space. However, since it is a multi-product production, the cost is very high, and it is rarely used.

[0006] Further, in Japanese Utility Model Laid-Open No. 61-151266, Japanese Utility Model Laid-Open No. 62-26867, Japanese Patent Laid-Open No. 62-40179 and Japanese Patent Laid-Open No. 1-304677, there are proposed methods for connecting conductors. However, in any of these methods, the connecting portion of the conductor is linear, and no technical idea of deforming the connecting portion into an arbitrary shape according to the shape of the mounting space is disclosed.

The present invention has been made in view of the above-mentioned problems, and the conductor portion of a conductive wire can be surely and firmly connected, and at the same time, the connecting portion can be easily and freely deformed, and any mounting space can be provided.

A deformable splice pipe according to one embodiment shown in FIG. 1 includes a braided mesh cylinder 1 for connecting a conductor portion 5 formed of a stranded wire of a conductive wire 4 and a solder sheet provided on the inner circumference of the braided mesh cylinder 1. It is composed of a tube 2 and a heat-shrinkable tube 3 for insulation that covers the braided mesh tube 1. The braided mesh cylinder 1 is formed by forming a deformable braided mesh cylinder having excellent conductivity into a cylindrical shape having substantially the same diameter as that of a conductor to be connected, and silver-plating this. It is formed to a suitable length. The solder sheet cylinder 2 is formed by arranging a solder of easily fusible metal in a cylindrical shape on the inner circumference of the braided mesh cylinder 1. Heat shrink tube 3
Is a tubular tube having an insulating property and a heat shrinkability, and is formed in such a size that the whole braided mesh tube 1 is tightly covered.

In this state, as shown in FIG. 2D, when the heat shrink tube 3 is heated from the outside by a heat gun or the like, first the heat shrink tube 3 shrinks and the two conductive wires 4a and 4b are fixed. When the heating further proceeds, the solder sheet cylinder 2 is melted, the braided mesh cylinder 1 and the conductor portions 5a and 5b are connected, and at the same time, the shrinkage of the heat shrinkable tube 3 is completed. This allows two conductors 4

Next, the conductor portions 5a and 5b of the conductors 4a and 4b.
A case will be described in which the connection part is deformed and connected according to the corner of the mounting space. When the conductor connecting portion is deformed, first, the procedure similar to that of the above-described embodiment is performed as shown in FIG.
Work up to the state of (b). Next, this Figure 2 (b)
In this state, the braided mesh cylinder 1 is deformed into an arbitrary shape. Then, after that, the heat-shrinkable tube 3 is moved, heated, and the like by the same procedure as in the above-described embodiment to complete the work. As a result, as shown in FIG. 3, the conductor wire connecting portion can be freely deformed into a shape adapted to a corner portion or the like in the housing.
