図１は従来のコネクタ（レセプタクル）９１の模式図である。同図に示すように、従来のコネクタ（レセプタクル）９１の筒型金具９１２に合成樹脂（ポッティング材）９１５を充填した場合、表面張力によって、筒型金具９１２の内壁に沿ってポッティング材の液面が上昇する（同図の破線丸囲い部分を参照）。内壁に沿って上昇したポッティング材が硬化することにより、相手方コネクタ９２の挿通を妨げ、コネクタの嵌合不良が発生する場合がある。 FIG. 1 is a schematic view of a conventional connector (receptacle) 91. As shown in the figure, when the tubular metal fitting 912 of the conventional connector (receptacle) 91 is filled with synthetic resin (potting material) 915, the liquid level of the potting material is applied along the inner wall of the tubular metal fitting 912 due to surface tension. (See the dashed circle in the figure). The hardening of the potting material that has risen along the inner wall may prevent the mating connector 92 from being inserted, resulting in poor fitting of the connector.

ポッティング材の液面上昇を冶具などで規制する方法もあるが冶具などを取り外す際に液だれが起こり、製品の他の部分にポッティング材が付着して嵌合不良、導通不良を引き起こす場合がある。 There is also a method of controlling the rise of the liquid level of the potting material with a jig, etc., but when removing the jig, liquid dripping may occur and the potting material may adhere to other parts of the product, causing poor fitting and poor continuity. ..

そこで本発明では、内壁に沿って液面上昇したポッティング材による嵌合不良を防ぐことができるコネクタを提供することを目的とする。 Therefore, an object of the present invention is to provide a connector capable of preventing fitting failure due to a potting material whose liquid level has risen along the inner wall.

本発明のコネクタは、シェルと、シェルに挿入されるボディと、ボディに挿通されシェルに収容されるコンタクトを含むコネクタである。シェルは、ポッティング材が注入される第１の筒状部と、第１の筒状部と同軸上に設けられ、第１の筒状部よりも内径が小さく、相手方コネクタが挿通される第２の筒状部と、第１の筒状部と第２の筒状部を接続する接続部を含む。 The connector of the present invention is a connector including a shell, a body inserted into the shell, and a contact inserted through the body and housed in the shell. The shell is provided coaxially with the first tubular portion into which the potting material is injected and the first tubular portion, has an inner diameter smaller than that of the first tubular portion, and has a second shell through which the mating connector is inserted. Includes a tubular portion of the above and a connecting portion connecting the first tubular portion and the second tubular portion.

以下、本発明の実施の形態について、詳細に説明する。なお、同じ機能を有する構成部には同じ番号を付し、重複説明を省略する。 Hereinafter, embodiments of the present invention will be described in detail. The components having the same function are given the same number, and duplicate description is omitted.

以下、図２、図３、図４を参照して実施例１のコネクタ１の構造を説明する。図２、図３、図４に示すように、本実施例のコネクタ１はリアケース１１と、シェル１２と、パッキン１３と、コンタクト１４と、ポッティング材１５と、ボディ１６と、シールドフレーム１７を含む。実施例１のコネクタ１は、防水コネクタである。 Hereinafter, the structure of the connector 1 of the first embodiment will be described with reference to FIGS. 2, 3, and 4. As shown in FIGS. 2, 3 and 4, the connector 1 of this embodiment includes a rear case 11, a shell 12, a packing 13, a contact 14, a potting material 15, a body 16, and a shield frame 17. Including. The connector 1 of the first embodiment is a waterproof connector.

図４に示すように、ボディ１６は、中央に凸部１６１を有する薄い板形状である。シェル１２は、略角筒形状の筒状部１２１と、筒状部１２１の下端を外側に延伸してなるフランジ１２２を含む。フランジ１２２にはシールドフレーム１７が接続される。筒状部１２１に凸部１６１が嵌りこみ、シェル１２にボディ１６が挿入される。 As shown in FIG. 4, the body 16 has a thin plate shape having a convex portion 161 in the center. The shell 12 includes a tubular portion 121 having a substantially square tubular shape, and a flange 122 formed by extending the lower end of the tubular portion 121 outward. A shield frame 17 is connected to the flange 122. The convex portion 161 is fitted into the tubular portion 121, and the body 16 is inserted into the shell 12.

ボディ１６の凸部１６１には、凸部１６１を表側から裏側に貫通するコンタクト挿通穴１６１１が設けられている。この実施例では、コンタクト挿通穴１６１１が６つ設けられているが、コンタクト挿通穴１６１１の数は任意である。コンタクト挿通穴１６１１には、コンタクト１４が挿通される。コンタクト１４は、シェル１２の筒状部１２１内に収容される。シェル１２の筒状部１２１の外周に、筒形状のパッキン１３が取り付けられる。ボディ１６、シェル１２、コンタクト１４、パッキン１３を組み立ててなる組立体は、リアケース１１に収容される。リアケース１１とシェル１２の隙間はパッキン１３によって塞がれる。筒状部１２１には、ポッティング材１５が注入される（後述）。 The convex portion 161 of the body 16 is provided with a contact insertion hole 1611 that penetrates the convex portion 161 from the front side to the back side. In this embodiment, six contact insertion holes 1611 are provided, but the number of contact insertion holes 1611 is arbitrary. The contact 14 is inserted into the contact insertion hole 1611. The contact 14 is housed in the tubular portion 121 of the shell 12. A tubular packing 13 is attached to the outer circumference of the tubular portion 121 of the shell 12. The assembly including the body 16, the shell 12, the contact 14, and the packing 13 is housed in the rear case 11. The gap between the rear case 11 and the shell 12 is closed by the packing 13. The potting material 15 is injected into the tubular portion 121 (described later).

＜筒状部１２１の構造＞
同図に示すように、シェル１２の筒状部１２１は、筒状部１２１の下端側であって、ボディ１６の凸部１６１と嵌合し、ポッティング材１５が注入される第１の筒状部１２１１と、筒状部１２１の上端側であって、第１の筒状部１２１１よりも内径が小さく、相手方コネクタが挿通される第２の筒状部１２１２と、第１の筒状部１２１１と第２の筒状部１２１２を接続する接続部１２１３を含む。なお、第１の筒状部１２１１と第２の筒状部１２１２は、同軸上に設けられる。 <Structure of tubular portion 121>
As shown in the figure, the tubular portion 121 of the shell 12 is a first tubular portion on the lower end side of the tubular portion 121, which is fitted with the convex portion 161 of the body 16 and into which the potting material 15 is injected. A second tubular portion 1212 on the upper end side of the tubular portion 121 and a tubular portion 121 having an inner diameter smaller than that of the first tubular portion 1211 and through which the mating connector is inserted, and a first tubular portion 1211. Includes a connecting portion 1213 that connects the and the second tubular portion 1212. The first tubular portion 1211 and the second tubular portion 1212 are provided coaxially.

この実施例において、接続部１２１３は、中空な錐台の側面と等しい形状である。別の表現では、この実施例において、接続部１２１３は、上方向に行くにつれて細くなるテーパーを付けたリング形状（筒形状）である。接続部１２１３は、絞り加工によって形成することができる。絞り加工によって接続部１２１３を形成する場合、追加工が不要であるため、製造コストの上昇を抑えることができる。 In this embodiment, the connecting portion 1213 has the same shape as the side surface of the hollow frustum. In other words, in this embodiment, the connecting portion 1213 has a ring shape (cylindrical shape) having a taper that becomes thinner toward the upward direction. The connecting portion 1213 can be formed by drawing. When the connecting portion 1213 is formed by drawing, no additional machining is required, so that an increase in manufacturing cost can be suppressed.

図５に示すように、ポッティング材１５を、第１の筒状部１２１１の上端まで注入した場合、従来技術と同様に、第１の筒状部１２１１、接続部１２１３の内壁に沿ってポッティング材１５の液面が上昇する。しかし、第１の筒状部１２１１よりも第２の筒状部１２１２の内径を小さくして同軸上に配置することによって、内壁に沿って液面上昇するポッティング材１５の位置と相手方コネクタ２の嵌合位置をずらしているため、両者の干渉を防ぐことができる。これにより、ポッティング材１５を安定して利用することができるだけでなく、接続部１２１３の高さｄを小さくできるため、製品の小型化に寄与する。
また、接続部１２１３は、垂直方向よりもさらにコネクタ１の内側方向にテーパーを付けた形状（シェル１２の内側から見て、いわゆるネズミ返し、オーバーハングの形状）であるため、表面張力よりも重力の影響が大きくなり、内壁に沿った液面上昇の度合いも小さくなる。 As shown in FIG. 5, when the potting material 15 is injected to the upper end of the first tubular portion 1211, the potting material is formed along the inner walls of the first tubular portion 1211 and the connecting portion 1213 as in the prior art. The liquid level of 15 rises. However, by making the inner diameter of the second tubular portion 1212 smaller than that of the first tubular portion 1211 and arranging them coaxially, the position of the potting material 15 whose liquid level rises along the inner wall and the position of the mating connector 2 Since the mating position is shifted, interference between the two can be prevented. As a result, not only the potting material 15 can be used stably, but also the height d of the connecting portion 1213 can be reduced, which contributes to the miniaturization of the product.
Further, since the connection portion 1213 has a shape in which the connector 1 is tapered inward rather than in the vertical direction (so-called rat guard, overhang shape when viewed from the inside of the shell 12), gravity is greater than surface tension. The effect of is large, and the degree of liquid level rise along the inner wall is also small.

＜変形例１＞
以下、図６を参照して変形例１のコネクタ１ａの構造を説明する。 <Modification example 1>
Hereinafter, the structure of the connector 1a of the modification 1 will be described with reference to FIG.

同図に示すように接続部１２１３ａは、第１の筒状部１２１１と第２の筒状部１２１２を接続し、第１の筒状部１２１１および第２の筒状部１２１２の軸方向と垂直な面で構成されてもよい。変形例１のコネクタ１ａは、実施例１と同様に、硬化したポッティング材１５と相手方コネクタ２との干渉を防ぐことができ、表面張力よりも重力の影響が大きくなることにより、内壁に沿った液面上昇の度合いも小さくなる。 As shown in the figure, the connecting portion 1213a connects the first tubular portion 1211 and the second tubular portion 1212, and is perpendicular to the axial direction of the first tubular portion 1211 and the second tubular portion 1212. It may be composed of various aspects. Similar to the first embodiment, the connector 1a of the modified example 1 can prevent the cured potting material 15 from interfering with the mating connector 2, and the influence of gravity is larger than the surface tension, so that the connector 1a is along the inner wall. The degree of liquid level rise also decreases.
