Abstract

PROBLEM TO BE SOLVED: To discharge water staying in a gap between a waterproof plug and a connector housing, thereby eliminating possibility of entrance of water in the housing. SOLUTION: A plurality of discharge holes 6 are formed at the end 1A of a connector housing 1 at the gap portion between a waterproof plug 5 installed at the end of a wire harness 3 and an open exit in the terminal housing chamber 2 in which one end of the connector housing 1 is opened 2A.

Description

本発明は、自動車用ワイヤハーネス等に使用される防水コネクタに関する。 The present invention relates to a waterproof connector used for an automobile wire harness or the like.

従来の防水コネクタとしては、図３に示すように、コネクタハウジング１に一端が開口２Ａされた複数の端子収容室２を有し、この各端子収容室２内にワイヤハーネス３の端部に接続された端子４とワイヤハーネス３の端部に装着された防水栓５とを収容し、この防水栓５で端子収容室２の開口２Ａを閉塞するようにした防水コネクタが一般的に知られている（特許文献１参照）。
特開２００４−１４１６８号公報（第３頁、図１） As a conventional waterproof connector, as shown in FIG. 3, the connector housing 1 has a plurality of terminal accommodating chambers 2 each having an opening 2 A, and is connected to the end of the wire harness 3 in each terminal accommodating chamber 2. A waterproof connector is generally known in which a terminal 4 and a waterproof plug 5 attached to an end of the wire harness 3 are accommodated, and the opening 2A of the terminal accommodating chamber 2 is closed with the waterproof plug 5. (See Patent Document 1).
Japanese Patent Laid-Open No. 2004-14168 (page 3, FIG. 1)

従来の防水コネクタでは、開口２Ａの出口側と防水栓５との間の隙間Ｓに水が溜まり、この水がハウジング１内に浸入することがあった。ハウジング１内への水の浸入を防止するために、防水栓５の材料とか形状等をいろいろ工夫したものがあるが、隙間Ｓに水が溜まると、浸入のおそれは生じるものであった。 In the conventional waterproof connector, water accumulates in the gap S between the outlet side of the opening 2 A and the waterproof plug 5, and this water may enter the housing 1. In order to prevent water from entering the housing 1, there have been various ideas on the material and shape of the waterproof plug 5, but when water accumulates in the gap S, there is a risk of intrusion.

そこで、本発明は、ハウジングの端子収容室の開口に水が溜まるのを防止した防水コネクタを提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a waterproof connector that prevents water from collecting in the opening of a terminal accommodating chamber of a housing.

上述の目的を達成するため、コネクタハウジングの一端が開口された端子収容室内のワイヤハーネスの端部に装着された防水栓と開口出口との間の隙間個所のコネクタハウジングの端部に複数の排水口を形成したものである。
ものである。 In order to achieve the above-mentioned object, a plurality of drains are provided at the end of the connector housing at the gap between the waterproof plug attached to the end of the wire harness in the terminal housing chamber in which one end of the connector housing is opened and the opening outlet. The mouth is formed.
Is.

本発明は、コネクタハウジングの一端が開口された端子収容室内のワイヤハーネスの端部に装着された防水栓と開口出口との間の隙間個所のコネクタハウジングの端部に複数の排水口を形成したので、防水栓と開口出口との間の隙間に水が溜まらなくなり、ハウジング内への水の浸入のおそれをなくした。 According to the present invention, a plurality of drainage ports are formed at the end of the connector housing at a gap between the waterproof plug attached to the end of the wire harness in the terminal housing chamber in which one end of the connector housing is opened and the opening outlet. As a result, water does not accumulate in the gap between the waterproof plug and the opening outlet, eliminating the risk of water entering the housing.

以下に、本発明の実施形態を図面を参照にして説明する。 Embodiments of the present invention will be described below with reference to the drawings.

図１では、コネクタハウジング１の端子収容室２の一端側の開口２Ａからワイヤハーネス３と端子４とをこの室２に挿入する。ワイヤハーネス３には防水栓５が装着され（図１では省略）、この防水栓５よりもコネクタハウジング１の開口２Ａ側の端部１Ａに複数の排水口６を形成した。この排水口６は、図示する実施形態では、切り込みであるが、複数の小孔であってもよい。 In FIG. 1, the wire harness 3 and the terminal 4 are inserted into the chamber 2 from the opening 2 A on one end side of the terminal housing chamber 2 of the connector housing 1. A waterproof plug 5 is attached to the wire harness 3 (not shown in FIG. 1), and a plurality of drain ports 6 are formed at the end 1A on the opening 2A side of the connector housing 1 with respect to the waterproof plug 5. The drain port 6 is a cut in the illustrated embodiment, but may be a plurality of small holes.

図２は、コネクタハウジング１の開口２Ａ側の端部１Ａの斜視図であり、３ヶ所切り込みを入れて排水口６を形成した。この切り込みの長さは、開口２Ａから防水栓５の個所までとするのがよい。また、２ヶ所あるいは４ヶ所以上であってもよい。 FIG. 2 is a perspective view of the end 1 A on the opening 2 A side of the connector housing 1, and the drain port 6 is formed by cutting three places. The length of the cut is preferably from the opening 2A to the waterproof plug 5 portion. Moreover, it may be two places or four places or more.

なお、図１において、符号７はコネクタハウジング１と図示しない相手方コネクタハウジングとの間を塞ぐシール材である。なお、コネクタハウジング１は、樹脂成形され、防水栓５はシリコンゴム等の合成ゴムから形成されている。 In FIG. 1, reference numeral 7 denotes a sealing material that closes the gap between the connector housing 1 and a mating connector housing (not shown). The connector housing 1 is resin-molded, and the waterproof plug 5 is formed from a synthetic rubber such as silicon rubber.
