側に口金のように露出して取付けられていた。``Prior Art'' In general, a plug for a jack has a structure in which conductive contact cylinder parts 2a, 2b, etc. are provided at the tip of an insulating handle part 1 in an insulated state from each other, as shown in FIG. has been done. And this contact cylinder part 2a,
2b..., the outer cylindrical portion 2a is for grounding. When this earthing cylinder part 2a is inserted into the guide cylinder part 5 of the jack body 3, the earthing metal fitting 4
However, conventionally, this grounding fitting 4 is formed in a cylindrical shape, and the guide tube part 5 on the front of the jack body 3
It was attached to the side, exposed like a cap.

しかるに現在のジヤツクは、口金状のアース金

きた。 However, in today's jacks, a grounding fitting 4 made of a leaf spring as shown by the chain line in FIG. 8 has come to be used instead of a base-shaped grounding fitting. Therefore, the base-like grounding fitting 4 is no longer necessary, and the guide tube portion 5 of the jack body 3 is now sometimes made entirely of plastic.

面倒であつた。[Problems to be Solved by the Invention] However, in order to retain the image of a conventional jack, it is required that a cap-shaped grounding fitting be provided as a decoration, even if it does not play any electrical role. Conventionally, these decorative caps were fixed to the jack body by caulking or press-fitting them into the jack body, but turning them was expensive and difficult to assemble.

８，８が形成されている。 Reference numeral 3 denotes a jack body, and this jack body 3 consists of a box-shaped housing 15 and an upper lid 16, and a contact piece (not shown) such as a leaf spring is provided inside, and is led out to the outside through terminals 17. There is. A cylindrical plug guide tube portion 5 is formed on one side of the jack body 3, integrally with the housing 15 and penetrating to the inside thereof. This plug guide cylinder part 5
A stepped portion 6 of a predetermined depth is formed inside the tip of the opening, and two guide grooves 7 are formed in the inner wall in the axial direction.
Further, engagement recesses 8, 8 are formed inside the guide grooves 7, 7, and penetrate to the side surface of the guide cylinder portion 5.

２，１２側から切り込まれている。 Next, reference numeral 9 is a decorative ring made of plastic and colored in a metallic color so that it looks like a grounding metal fitting as a pseudo-earth.The inner diameter of the pin guide hole 14 of this decorative ring 9 is for grounding the plug. It has the same diameter as the cylindrical part (corresponding to the symbol 2a in Fig. 8),
Further, the outer diameter is the same as the inner diameter of the guide tube portion 5. A flange portion 10 that fits into the step portion 6 of the guide tube portion 5 is formed at one end of the outer side of the decorative ring 9, and two protrusions 11, 1 are provided on the outer periphery in the axial direction.
1 is formed to fit into the guide grooves 8, 8, and locking protrusions 12, 12 are provided at the tips of these protrusions 11, 11 facing outward. A taper is formed to facilitate insertion. Furthermore, protrusion 1
Cut grooves 1 are provided on both sides of 1 and 11 to provide elasticity.
3 and 13 are attached to the locking protrusion 1 so that the flange 10 side remains.
It is cut from the 2nd and 12th sides.

このような構成において、装飾リング９の突条

係合する。 In such a configuration, the decorative ring 9 is press-fitted while the protrusions 11, 11 of the decorative ring 9 are fitted into the guide grooves 7, 7 of the guide tube portion 5. Then, protrusion 1
The locking protrusions 12 and 11 enter the guide grooves 7 and 7 while sliding and curving inwardly against elasticity. Then, the locking protrusions 12, 12 are connected to the engaging recess 8,
When it reaches position 8, it elastically returns and engages. At this time, the flange portion 10 of the decorative ring 9 tightly engages with the stepped portion 6.

［考案の効果］ (1) 装飾リング９をプラスチツクで成型加工した
ので、従来の金属挽物に比し、加工が簡単であ
