本考案は、水滴などのかかる環境で使用できる
電気コネクタの尾端を封止するための防水栓に関
する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a waterproof plug for sealing the tail end of an electrical connector that can be used in such environments as water droplets.
従来の技術
防水コネクタは、水などの液体がコネクタ相互

通したゴム栓等を嵌合して密封することが行われ
ている。BACKGROUND OF THE INVENTION Waterproof connectors must not only prevent liquids such as water from entering the joints between the connectors, but also have a structure that does not allow water or the like to enter the connector itself. Since the electric wire connector is constructed by inserting and fixing a terminal to which an electric wire is fixed into a cylindrical housing, in order to make it waterproof, the housing must have a cylindrical sealed structure. The opening at the tail end is sealed by fitting a rubber plug or the like into which an electric wire is inserted.

第５〜７図に示すように筒状の樹脂製スペーサＢ
をゴム製の筒状栓体Ｃの後部に包埋して防水栓Ａ
を形成したものがある。 When sealing with such a rubber plug, it is necessary to securely lock the terminal in the specified position within the housing, and to secure the rubber plug itself so that it does not escape. There have been proposals to make the assembly of the waterproof connector easier and more reliable by providing a spacer made of hard resin to suppress the end surface, and by providing a terminal pressing member that penetrates from the rear end surface to the front end surface of the rubber plug. As an example of such a waterproof plug, a cylindrical resin spacer B is used as shown in FIGS.
is embedded in the rear part of the rubber cylindrical plug C to create a waterproof plug A.
There are some that have formed.
スペーサＢは、防水栓Ａの後端部を構成する環
状部b1と筒状栓体Ｃの壁内に包埋される筒部b2と

形成されたゴム製の筒状体であり、その内面c1は
挿通された電線Ｄの外面との間を密封できるよう
になつており、また外面c2はハウジングＥの内面
との間を密封できるようになつている。 The spacer B is composed of an annular part b 1 that constitutes the rear end of the waterproof plug A and a cylindrical part b 2 that is embedded in the wall of the cylindrical plug C. A window b3 is provided to ensure this. The plug C is a rubber cylindrical body formed to enclose the cylindrical part b2 of the spacer B from the inside and outside, and its inner surface c1 can seal the space between it and the outer surface of the electric wire D inserted therein. Moreover, the outer surface c2 can be sealed with the inner surface of the housing E.
しかし、このような防水栓Ａには、線径の異な

制限されているので太い電線Ｄは挿通しにくい上
に、無理に挿通すると栓体Ｃの変形がc2部分に集
中して膨出し、ハウジングＥへ装着がしにくくな
るという欠点があつた。 However, in such a waterproof plug A, two or three types of electric wires with different wire diameters are selected and inserted in consideration of waterproof performance or workability, but the rubber plug C itself Since the deformation is limited by the resin cylindrical part b2 , it is difficult to insert the thick electric wire D, and if the wire D is inserted forcibly, the deformation of the plug C will concentrate on the c2 part and bulge out, leading to the housing E. The drawback was that it was difficult to install.
解決しようとする問題点
上述のような従来技術の防水栓は、太い電線に
は使用しにくく、また細い電線では隙間ができ易
いので、電線の太さに応じた寸法の防水栓を数種
常備しておく必要があり、これを選択して使用し
なければならない不便があつた。Problems to be Solved The conventional waterproof plugs described above are difficult to use with thick wires, and gaps tend to form with thin wires, so several types of waterproof plugs with dimensions that correspond to the thickness of the wires are always available. There was an inconvenience in having to select and use this.
上記の如き事情に於て、使用上の許容範囲が広

る。Means for Solving the Problem The object of this invention is to provide a spacer made of a hard elastic material, in which a plurality of flexible pins having an arcuate cross section are arranged in an annular shape and protrude forward from an annular body; A monopolar waterproof connector characterized in that a cylindrical plug made of a soft elastic material is integrally connected by coaxially embedding the pin in the rear wall of the plug. This is achieved by using a watertight stopper.

が望ましい。 The outer wall surface of this cylindrical plug body is in close contact with the inner surface of the tail portion of the housing of the waterproof connector, and the inner wall surface thereof is formed with annular folds or the like so as to be in close contact with the outer surface of the electric wire and seal the gaps. It is desirable that the

ている。 The spacer 2 is formed with enough room in the center to allow an electric wire to pass through, and includes an annular part 21 that constitutes the rear end of the waterproof plug, and a pin protruding from one side of the annular part 21 in a direction parallel to the axis. It consists of part 22. The pin portions 22 are formed, for example, in the shape of a plate having an arcuate cross section, and a plurality of pin portions 22 are provided via slits 23 so as to form a ring surrounding the axis. Flexibility in the radial direction is ensured by providing a window 24 or the like.

が形成してある。 The plug body 3 is formed into a cylindrical shape so as to completely embed the pin part 22 of the spacer 2, and the center part is a through hole through which the electric wire 4 can be inserted.
It extends forward in a nozzle shape. The inner surface of the plug body 3 is formed with annular ridges or folds 31 so that it fits well with the outer surface of the electric wire 4 and can be sealed, and the outer surface of the plug body 3 is also provided with a connector. Annular ridges or folds 32 are formed so as to fit well with the inner wall surface of the housing 5 and to enable sealing.

つて同時に外方へ撓み栓体３が一様に拡張するの
で、電線４の挿通を容易に行なうことができる。 When the thick electric wire 4 is inserted into the waterproof plug 1 of the present invention constructed in this way, the plug body 3 is pushed out from the inside, but the pin portion 22 of the spacer 2 simultaneously bends outward as a result. 3 expands uniformly, the electric wire 4 can be inserted easily.

つた状態で封止されることとなる。 When the waterproof plug 1 with the electric wire 4 inserted therein is fitted into the tail portion of the connector housing 5, the plug body 3 is pushed from the outside, but the pin portion 22 of the spacer 2 simultaneously bends inward, and the electric wire The annular ridge 31 is deformed by pressing the outer surface of the stopper 4, and the annular ridge 32 on the outer surface of the plug 3 is similarly deformed and fitted. Therefore, the gap between the electric wire 4 and the plug 3 and the gap between the housing 5 and the plug 3 are balanced and sealed.
このため太い電線を挿入することが容易になる

た。 This makes it easy to insert thick electric wires, and even if a thick electric wire is inserted into the waterproof plug, only one part of the waterproof plug will not expand concentratedly, so it is not difficult to attach it to the housing, and it is not difficult to insert thin electric wires. When the waterproof plug is attached to the housing, only the gap with the housing is sealed, and the gap with the electric wire is no longer incompletely sealed.
