Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plug cover.
[0002]
[Prior art]
Conventionally, when plugs are inserted into outlets in places with high humidity, plug cover 20 is attached to plug P ₀ as shown in Fig. 10 to prevent tracking due to dust and dirt accumulated between plug terminals. Then, the plug P ₀ and the plug cover 20 are integrated and inserted into an outlet.
[0003]
[Problems to be solved by the invention]
However, as shown in FIG. 10, the conventional plug cover 20 has a short length L ₀ in the front-rear direction, and when attached, when the finger is moved backward (relatively) with respect to the plug P ₀ , Slipped and was difficult to wear. Further, the conventional plug cover 20 was easily removed from the plug P ₀ unexpectedly. And it could only be used for a single type of plug.
[0004]
Therefore, an object of the present invention is to provide a plug cover that can be easily attached and can prevent tracking. Another object of the present invention is to provide a plug cover that can be used for a plurality of types of plugs (various dimensions) without unexpectedly leaving the plug.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, a plug cover according to the present invention includes a front wall having a pair of holes into which a pair of plug terminals are inserted, and an upper wall that is connected to the front wall and substantially surrounds the plug. - have a lower wall, left side wall and right wall, the direction the hole portion, when the plug pin is plugged, so as to closely plug terminals elastically deformed to protrude forward, reducing the pore size and has a thin protruding piece was stretched to a thickness T ₁ of the said thin projected pieces, set to 0.1mm ≦ T ₁ ≦ 0.8mm, the upper wall and lower wall the length of the plug with substantially equal to the main body, set a short length of the left wall and right wall than said length dimension, notch is formed, and the thickness dimension of the left wall and right wall , is set to be smaller than the thickness dimension of the upper wall and lower wall, in the upper and lower walls, disconnect difference between Cords Those having a wall thickness forming protrusion having a sliding prevention 凹弯 curved surface to prevent the fingers from slipping when. Further, an encircling elastic membrane portion is formed around the front wall so as to project forward.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
[0007]
FIG. 1 shows a use state of a plug cover according to the present invention. That is, the plug cover is made of silicon rubber and is attached to the plug P. Then, by plugging the plug terminals Q, Q of the plug P with the plug cover attached into the outlet C, it is possible to prevent tracking due to intrusion of dust, dirt, and moisture. Since the plug cover is made of silicon rubber, when the plug P is inserted into and removed from the outlet C, the finger does not slip and the plug P can be inserted and removed easily and reliably.
[0008]
2 to 5, the plug cover has a front wall 2 having a pair of holes 1 and 1 into which a pair of plug terminals Q and Q (see FIG. 1) are inserted, and is connected to the front wall 2. The upper wall 3, the lower wall 4, the left side wall 5, and the right side wall 6 are provided so as to substantially surround the plug P.
[0009]
The length dimension L _{2 of the} left side wall 5 and the right side wall 6 is set to be shorter than the length dimension L _{1 of the} upper wall 3 and the lower wall 4, and the notch 8 is formed. Or if the length L ₂ of the left side wall 5 and right wall 6 than the length L ₁ of the upper wall 3 and lower wall 4 is long, the length L ₁ of the upper wall 3 and lower wall 4 and the left side wall 5 • If the length L ₂ of the right side wall 6 is equal to, less likely attached to the plug P (see FIG. 1).
[0010]
The thickness dimension T ₂ of the left side wall 5 and the right side wall 6 is set smaller than the thickness dimension T ₃ of the upper wall 3 and the lower wall 4. When the thickness dimension T ₂ is larger than the thickness dimension T ₃ , or when the thickness dimension T ₂ is equal to the thickness dimension T ₃ , it is used for the plug P having different left and right width dimensions (see FIG. 1). Can not do it.
[0011]
A surrounding elastic membrane portion 9 is formed around the front wall 2 so as to project forward and expand forward.
The upper wall 3 and the lower wall 4 are provided with a thickness forming protrusion 11 having an anti-slip concave curved surface 10 for preventing a finger from slipping when the plug P (see FIG. 1) and the outlet C are inserted and removed.
[0012]
6 and 8 show a state before the plug cover is attached to the plug P (see FIG. 1), and FIGS. 7 and 9 show a state where the plug cover is attached to the plug P. The hole 1 is a thin projecting piece extending in a direction to reduce the hole size so that the plug terminal Q (see FIG. 1) is inserted and elastically deformed into a forward projecting shape and is in close contact with the plug terminal Q. Part 7. In other words, as shown in FIG. 9, the thin protruding piece 7 is elastically deformed from a single-character shape into a curved shape, and is in close contact (pressure contact) with the plug terminal Q as indicated by arrows F and F, thereby preventing intrusion of dust and moisture. To prevent.
[0013]
The thickness dimension T ₁ of the thin projecting piece 7 is set to 0.1 mm ≦ T ₁ ≦ 0.8 mm. When the thickness dimension T ₁ is T ₁ <0.1 mm, the strength is inferior, and the thin protrusion 7 may be damaged. Further, when the thickness dimension T ₁ is 0.8 mm <T ₁ , it is difficult to be deformed and the plug P (see FIG. 1) may not be easily inserted.
[0014]
In the present invention, the design can be changed, and for example, the surrounding elastic membrane portion 9 may be omitted.
[0015]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists an effect described below.
[0016]
It is possible to prevent tracking (good lever to claim 1, 2).
[0017]
(According to claim 1) is good close contact with the plug terminal Q. The surrounding dust, dust and moisture can be prevented from entering, and tracking can be prevented more reliably.
Further, it has an appropriate strength and can be in close contact with the plug terminal Q reliably. Then, as possible out to the periphery of the dust, to prevent penetration of moisture, preventing more reliably tracked.
Further, it can be easily attached to the plug P.
Further, the left side wall 5 and the right side wall 6 are elastically deformed and easily stretched, and can be used for a plurality of types of plugs P (of various dimensions).
[0018]
Further, it is easy to apply a force when held with a finger, and the plug P and the outlet C can be reliably inserted and removed without slipping in the longitudinal direction.
[0019]
(According to claim 2) Dust and dust do not enter the front side of the front wall 2, and tracking can be prevented more reliably.
