せてTIG溶接により接合していた。[Prior Art] A connector is attached to the connection terminal of a cable in order to connect the conductor within the cable.
As shown in the third figure, in this connector, a metal connector case 2 is attached to the terminal end of a cable 1, and a cable conductor is inserted into the case. The butt edges of such connector cases are welded, and conventionally this welding has been performed by TIG welding by abutting the weld joints 3 of the connector cases to be connected.

クタケースに適用し得るものではなかつた。 As described in JP-A No. 56-102394, the end surfaces of the pipes are provided with concave and convex portions or stepped connecting portions that can fit into each other, as well as welding concave surfaces, and these connecting portions are fitted to connect the pipes to each other. There is a known method of welding piping that aligns the center of the pipe, but this method is only a hollow pipe and does not take into consideration the protection of the objects inside, so it cannot be applied to cable connector cases. It wasn't something I could get.

要しコスト高になるという問題点があつた。[Problems to be Solved by the Invention] When the weld joint 3 is butt welded as described above, the weld metal grains adhere to the cable conductor 4 and the insulator in the case due to melting and scattering of the weld metal, causing damage to the cable. There is a risk of impairing the characteristics and causing insulation deterioration.For this reason, conventionally, an inner ring has been inserted inside the connector case, but this has had the problem of requiring time and effort to manufacture and increasing costs.
また、コネクタケースが厚肉のものでは溶接熱
量が大なのでコネクタ絶縁材等が溶接時の高熱に
より変質劣化するという問題点があつた。 In addition, if the connector case is thick, the amount of welding heat is large, so there is a problem that the connector insulating material and the like are deteriorated due to the high heat during welding.
そこで本考案は溶接の溶接金属粒がコネクタケ

An outer flange 8 for blocking metal particles is formed, an outer stepped notch 9 is provided at the edge of the other case plate to form an inner flange 10 for blocking weld metal particles, and the outer flange 8 is formed as an inner flange. The tip 8' of the outer flange 8 overlaps the edge 10.
A welded metal cut-off type cable connector case is constructed by welding the step edge 9' of the outer stepped notch 9 to the step edge 9' of the outer stepped notch 9.

溶け落ちや飛散が防止されることになる。[Function] As mentioned above, the case plate edge of the connector case is welded to the tip 8' of the outer flange 8 and the outer stepped notch 9.
There is an inner flange 10 for blocking weld metal grains on the lower side of this welding part, so the weld metal particles are blocked by this, and welding is performed on this inner flange 10. Since the outer flanges 8 for blocking metal grains overlap, weld metal grains do not enter the case, and are therefore prevented from burning through or scattering onto the cable inside the case.

An inner stepped notch 7 is provided on the inside of the edge of the case plate 6 to form an outer flange 8 for blocking weld metal particles, and an outer stepped notch 9 is provided on the outside of the edge of the other case plate 6. An inner flange 10 for blocking weld metal particles is formed.

ので溶融金属粒のケース内の侵入が防止される。 The tip edge 8' of the abutted outer flange edge 8 and the stepped edge 9' of the outer stepped notch 9 are welded with a torch 5 to join the edges of both case plates 2 and 6 together. Since there is an inner flange edge 10 for blocking weld metal grains inside the abutting portion of the tip edge 8' and step edge 9' to be welded, the molten red-hot metal particles are blocked by this inner flange edge 10. This prevents weld metal particles from melting down or scattering onto the cable inside the connector case. Furthermore, since the outer flange 8 overlaps the inner flange 10, molten metal particles are prevented from entering the case.

困難である。 In addition, the above-mentioned outer flange edge 8 for blocking weld metal particles is
The wall thickness d1 is set to 0.3 to 2 mm, and the length l1 is set to l1≧1 mm. In addition, the inner flange edge 10 for blocking weld metal particles has a wall thickness d2 of D-d1 (where D is the wall thickness of the case plate).
and set the length l2 to l2≧1mm. If the thickness d1 of the outer flange edge 8 for blocking weld metal particles is less than 0.3 mm, the weld metal will condense into beads and good welding will not be possible.
If it is more than mm, the welding heat will be excessive and there is a risk of deteriorating the cable material inside the connector case.
The optimal thickness d1 is within the range of 0.3 to 2 mm.
Also, the lengths l1 and l2 of both the outer and inner collar edges 8 and 10 are 1
If the thickness is less than mm, it is difficult to prevent molten metal from burning through or scattering.

The thickness d1 of the outer flange edge 8 for blocking weld metal particles is 1 mm.
The thickness d2 of the inner flange edge 10 for blocking weld metal particles is 1 mm.
When comparing the lengths of the flange edges of the connector cases, it was found that the length l1 of the outer flange edge 8 was
When the length l2 of the inner flange 10 was 0.5 mm and the length l2 of the inner flange 10 was 0.3 mm, molten metal particles melted down and adhered to the cable conductor inside the connector case, but when the length l1 of the outer flange 8 was 1.0 mm,

When comparing the thickness of the flange edge of the connector case, it was found that the thickness d1 of the outer flange edge 8 was
When the thickness d2 of the inner flange edge 10 was 0.2 mm and the thickness d2 of the inner flange edge 10 was 2.8 mm, the molten part condensed into beads and good welding could not be achieved. Also, when d1 was 2.2 mm and d2 was 0.8 mm, the cable material inside the connector case deteriorated, but when the thickness d1 of the outer flange 8 was 0.3 mm, 1.2 mm, and 2.0 mm, the thickness of the inner flange 10 was When the distance d2 was 2.7 mm, 1.8 mm, and 1.0 mm, the above-mentioned trouble did not occur.
