Description

Description: TECHNICAL FIELD The present invention relates to a plug adapted to be connected to a connection terminal of an electronic device, and more specifically, an identification symbol indicating the use of the plug can be displayed by a retrofit. The present invention relates to a plug with a display.

(Prior Art) This type of conventional plug with a display, to which a sticker with an adhesive material is attached, has a problem that the sticker peels off during handling or due to aging. To eliminate this problem, there is a technique of casting an identification code when molding a plug.

(Problems to be Solved by the Invention) However, the plug produced by the technique has a problem that its versatility is lacking because its use is limited to the use of the identification code that has been cast.

In the present invention, except for the above-mentioned conventional problems, a plug suitable for the intended use can be obtained by retrofitting the identifying member on which the identification symbol according to the application is displayed, and further, the identifying member is retrofitted. However, it is an object of the present invention to provide a plug with a display in which the attached state is firmly maintained.

 The configuration of the present invention is as follows.

(Means for Solving the Problems) In the present invention, in a plug in which a connecting member for a connection terminal is provided in a part of the base body, while a cord is extended from the other part of the base body, Is a separate body, and has an identification member having an identification mark on the front surface and a protrusion at the eccentric position on the back surface, while corresponding shape for fitting the identification member to the base body. And a recess having a depth equal to or larger than the thickness dimension of the identification member is provided, and a fitting hole for fitting the projecting piece is provided at a position corresponding to the projecting piece at the bottom of the recess, and the fitting is performed. In a state where the projecting piece is fitted in the dowel hole, the identification member is fitted in the concave portion so that both can be fixed with an adhesive.

(Operation) A plug for a desired application is completed by fitting and fixing an identification member having a desired identification symbol in the recess of the base. When the identification member is fitted in the recess, the orientation of the identification member with respect to the base body is fixed because of the presence of the protrusion and the fitting hole.

(Example) Hereinafter, drawings showing an example of the present application will be described. First
In FIG. 4 to FIG. 4, reference numeral 1 is a connection cord, which is used for connecting electronic devices to each other, for example, an AV television and a VTR,
It is composed of a plurality of cords 2 bundled with each other and plugs 3 with a display attached to both ends of each cord 2, respectively. 2a is a cord stopper, which is movable along the cord 2. In the plug 3, reference numeral 4 denotes a base, which is made of a synthetic resin material such as soft vinyl chloride, and has a display portion 4a for identifying each of the plurality of plugs on its side surface. Reference numeral 5 denotes a connecting member projecting from one end of the base body 4, which comprises a rod-shaped central conductor 6 and a cylindrical outer conductor 7 arranged coaxially with the central conductor 6. Reference numeral 8 denotes an outer cover, which is formed integrally with the base body 4.
The center conductor 6 and the outer conductor 7 are connected to the center conductor and the outer conductor of the cord 2 inside the base body 4, respectively. A holding member 10 is for holding the cord 2 in a stable manner, and is formed integrally with the substrate 4. 11 is a holding member 10
With a protective member made of one material (also called bushing),
This is for preventing the cord 2 from being bent, and is made thinner toward the tip end portion so that it can be flexibly deformed according to the bending of the cord 2.

Next, the structure of the display unit 4a will be described in detail. 12
Is an identification member that is separate from the base body 4, has an identification mark 13 recessed on the front surface, and has a projecting piece 14 at the eccentric position on the back surface. As shown in FIGS. 2 and 4, the identification member 12 has different identification symbols 13, and various types of synthetic resin materials such as soft vinyl chloride are manufactured. Further, the color of the identification member 12 is different from the color of the base body 4 (for example, gray),
Further, those having different identification symbols 13 can be made different from each other. For example, an identification member whose identification code 13 is "L"
12 is white, "R" is "red", "V" is yellow,
"A" is black. Next, 16 is a concave portion provided in the base body 4, which has a shape corresponding to that of the identification member 12 and has a depth of
It is formed to have a thickness of 12 or more, that is, equal to or deeper than that. Reference numeral 17 denotes a fitting hole provided at the bottom of the recess 16, which is provided at an eccentric position corresponding to the projecting piece 14. Reference numeral 18 indicates a recess for releasing excess adhesive. In FIG. 3, reference characters A to
An example of the dimensions of each part indicated by H is as follows. A =
8.9, B = 1, C = 1.9φ, D = 1, E = 9.0, F = 1.3,
G = 2φ, H = 1.4. The unit is mm.

Next, in the display section 4a, an identification member for the base body 4
The mounting of 12 will be described with reference to FIG. First, as shown in (A), a small amount of adhesive (a known gel adhesive for vinyl chloride) 20 is applied to the entrance of the fitting hole 17. Next, as shown in (B) and (C), the identification member 12 is pushed into the recess 16 in such a direction that the protruding piece 14 fits into the fitting hole 17. This allows the identification member
12 is adhered to the base body 4 and both are integrated.

In the above process, the adhesive 20 is spread by the protrusion 14 so as to be applied to the inner peripheral wall surface of the fitting hole 17. Therefore, the bonding area between the inner peripheral surface of the fitting hole 17 and the outer peripheral surface of the projecting piece 14 becomes very large, and the bonded state of both becomes extremely firm.

Further, in the above case, even if the adhesive 20 comes out from the fitting hole 17, since it is between the bottom surface of the recess 16 and the lower surface of the identification member 12, the adhesive that has come out is hidden by the identification member 12, and the plug is plugged. The appearance as is kept good. Still excess adhesive 20
Enters the recess 18 and is prevented from flowing out to a visible place.

The identification member 12 adhered as described above firmly adheres the outer peripheral surface of the projecting piece 14 and the inner peripheral surface of the fitting hole 17 in a wide area even if a force to pull it out from the recess 16 is applied. Moreover, since the direction of the force is substantially parallel to the direction of the adhesive surface, the proof stress of the adhesive surface against the force is extremely large, and therefore the discriminating member 12 is surely prevented from falling off. .

Next, FIG. 6 shows an adhesive when the identification member 12 is attached.
It shows an example in which 20 is attached to the hole edge of the fitting hole 17. Even in this case, the adhesive 20 is (A), (B),
As shown in the process of (C), it spreads and a firm adhesive state can be achieved.

(Effects of the Invention) As described above, in the present invention, the identification member 12 is attached to the base body 4 of the plug 3 so that the plug 3 is connected to the corresponding connection terminal among the many connection terminals. In this case, the presence of the identification member 12 has an effect of identifying the correspondence relationship at a glance.

Moreover, since the identification member 12 has a structure different from that of the base body 4, a plug maker can attach the identification member 12 to a plug of a semi-finished product, which has been mass-produced in advance without the identification member, so that the plug can be used in accordance with the purpose. In addition, since the plug of the semi-finished product and the identification member are different members, there is a possibility that a colorful plug can be obtained by making their colors different from each other.

Further, when the identification member 12 is attached to the base body 4, the identification member
Protrusions 14 are provided on the back surface of 12 at eccentric positions, and recesses 16 of the base 4 are provided.
In addition, since the fitting hole 17 is provided at the corresponding position, the identification symbol is naturally oriented in the designed direction with respect to the base body 4, and the operator can mount in the wrong orientation without paying special consideration. There is.

Further, as described above, even if the identification member 12 is a retrofit,
Since it is fitted in the concave portion 16, even if the hand touches the identifying member 12 during use, the identifying member 12 is not fitted with the concave portion 16
Only the force of pushing the inside is applied, and the effect that the attached state of the identification member 12 is maintained.
