　このピンヘッダーと称される形式のコネクタの例としては、例えば、図１３乃至図１５に示されるものが知られている（特許文献１参照）。
　図１３は、コネクタの要部の部分断面を含む斜視図であり、図１４は、図１３に示すコネクタに密封剤を充填したときの斜視図であり、図１５は、コネクタを電子機器装置に実装したときの断面図である。 Conventionally, a connector called a pin header has been used as a connector mounted on an electronic device.
As an example of a connector of this type called a pin header, for example, those shown in FIGS. 13 to 15 are known (see Patent Document 1).
13 is a perspective view including a partial cross section of a main part of the connector, FIG. 14 is a perspective view when the connector shown in FIG. 13 is filled with a sealing agent, and FIG. It is sectional drawing when mounted.
　図１３に示すように、コネクタ１１０は、モールド成形された絶縁性のハウジング１１１に複数の金属製のピン状のコンタクト１１２を取り付けてなる。ハウジング１１１の上面１１１ａには凹部１１５が形成されている。そして、その凹部１１５の周縁部にはフランジ部１１３がハウジング１１１の側面から突出して形成されている。凹部１１５には、その凹部１１５の底面１１５ａを一方の開口部とし、ハウジング１１１の下面１１１ｂを他方の開口部とした貫通孔をなす複数のコンタクト挿入孔１１６が形成されている。各コンタクト１１２は、コンタクト挿入孔１１６に挿入されることによって、ハウジング１１１に取り付けられる。そして、図１４に示すように、凹部１１５には密封剤が充填されて密封剤層１１８が形成されている。 As shown in FIG. 13, the connector 110 is formed by attaching a plurality of metal pin-shaped contacts 112 to a molded insulating housing 111. A recess 115 is formed in the upper surface 111 a of the housing 111. A flange 113 is formed on the periphery of the recess 115 so as to protrude from the side surface of the housing 111. The recess 115 is formed with a plurality of contact insertion holes 116 forming a through-hole having the bottom surface 115a of the recess 115 as one opening and the lower surface 111b of the housing 111 as the other opening. Each contact 112 is attached to the housing 111 by being inserted into the contact insertion hole 116. And as shown in FIG. 14, the recessed part 115 is filled with the sealing agent, and the sealing agent layer 118 is formed.
　そして、このコネクタ１１０は、図１５に示すように、コネクタ１１０は、コネクタ１１０が取り付けられる電子機器装置４００の内部と外部との境界にハウジング１１１を位置させて設置される。コネクタ１１０の上面１１１ａ側（電子機器装置４００の内部）においては、電子機器装置４００の内部に設置された基板４１０にコンタクト１１２が取り付けられる。また、コネクタ１１０の下面１１１ｂ側（電子機器装置４００の外部）においては、嵌合凹部５１０が形成された雄型コネクタ５００がコンタクト１１２に接続される。 As shown in FIG. 15, the connector 110 is installed with the housing 111 positioned at the boundary between the inside and the outside of the electronic device 400 to which the connector 110 is attached. On the upper surface 111 a side of the connector 110 (inside the electronic apparatus device 400), the contact 112 is attached to the substrate 410 installed in the electronic apparatus device 400. Further, on the lower surface 111 b side of the connector 110 (outside of the electronic device apparatus 400), the male connector 500 in which the fitting recess 510 is formed is connected to the contact 112.
　このように、図１３乃至図１５に示した従来のコネクタ１１０は、凹部１１５を設け、凹部１１５に密封剤を充填することにより、コンタクト挿入孔１１６における気密性及び液密性が確保される。密封剤としては、例えば、接着性を有する液体状の樹脂が採用される。
　これは、コネクタ１１０が取り付けられる電子機器の内部に対し、外部からの水分や埃等がコンタクト挿入孔１１６を介して侵入することを防止するためである。 As described above, the conventional connector 110 shown in FIGS. 13 to 15 is provided with the recess 115, and the recess 115 is filled with the sealing agent, so that the air tightness and the liquid tightness in the contact insertion hole 116 are ensured. As the sealant, for example, a liquid resin having adhesiveness is employed.
This is to prevent moisture, dust, and the like from the outside from entering through the contact insertion hole 116 into the electronic device to which the connector 110 is attached.
　ここで、凹部１１５に密封剤を充填する場合、密封剤の充填量、又は凹部１１５内に形成される密封剤層１１８の高さが適正であるか否かを判定する必要がある。密封剤層１１８の適正な高さとは、コンタクト挿入孔１１６における気密性及び液密性が確保できる密封剤の充填量を凹部１１５に充填したときの高さである。密封剤層１１８の高さは、凹部１１５の底面１１５ａから密封剤層１１８の上面１１８ａまでの距離を測定することにより得られる。 Here, when the recess 115 is filled with the sealant, it is necessary to determine whether or not the filling amount of the sealant or the height of the sealant layer 118 formed in the recess 115 is appropriate. The appropriate height of the sealant layer 118 is the height when the recess 115 is filled with a sealant filling amount that can ensure airtightness and liquid tightness in the contact insertion hole 116. The height of the sealant layer 118 is obtained by measuring the distance from the bottom surface 115a of the recess 115 to the top surface 118a of the sealant layer 118.
　密封剤の充填量、又は密封剤層１１８の高さの判定方法としては、例えば、下記（１）乃至（４）等が挙げられる。
（１）密封剤を供給する供給装置において、凹部１１５に供給された密封剤の量を測定し、その量を凹部１１５に充填された密封剤の量とする方法。
（２）本体部に対して摺動可能なプランジャーを有する接触式変位センサーを用いて、密封剤層１１８の上面１１８ａに押し当てたプランジャーの摺動距離により、上面１１８ａから凹部１１５の内壁の上端までの寸法を測定し、密封剤層１１８の高さを算出する方法。
（３）密封剤を固化させた後、破壊検査を行って密封剤層１１８の高さを測定する方法。
（４）レーザ光などを用いて非接触で密封剤層１１８の高さを測定する方法。
特開平６－２９０５２号公報 Examples of the method for determining the filling amount of the sealant or the height of the sealant layer 118 include the following (1) to (4).
(1) A method of measuring the amount of the sealing agent supplied to the recess 115 in the supply device for supplying the sealing agent, and setting the amount as the amount of the sealing agent filled in the recess 115.
(2) The inner wall of the recess 115 from the upper surface 118a by the sliding distance of the plunger pressed against the upper surface 118a of the sealant layer 118 using a contact type displacement sensor having a plunger slidable with respect to the main body. The method to measure the dimension to the upper end of, and calculate the height of the sealant layer 118.
(3) A method of measuring the height of the sealant layer 118 by performing a destructive inspection after the sealant is solidified.

　しかしながら、上記（１）の測定方法では、密封剤の供給時の条件が常に一定ではない可能性が高く、密封剤の供給量と、凹部１１５に実際に充填された密封剤の充填量との間に誤差が生じやすいため、密封剤の供給量をもって密封剤の充填量と見なすには、信頼性が低かった。
　また、上記（２）の算出方法では、密封剤層１１８が柔らかい材料であると、プランジャーに押圧された密封剤層１１８の上面１１８ａが変形し、適正な判定及び判定ができない問題があった。 However, in the measurement method of (1) above, it is highly likely that the conditions at the time of supplying the sealing agent are not always constant, and the amount of the sealing agent supplied and the amount of the sealing agent actually filled in the recess 115 are Since an error is likely to occur in the meantime, it was not reliable to regard the supply amount of the sealant as the filling amount of the sealant.
Further, in the calculation method of (2), when the sealant layer 118 is a soft material, the upper surface 118a of the sealant layer 118 pressed by the plunger is deformed, and there is a problem that proper determination and determination cannot be performed. .
　また、上記（３）の測定方法では、破壊検査であるため、測定値の信頼性は高いが、全ての製品について破壊試験を行うことができないという問題がある。
　更に、上記（４）の方法では、密封剤として、透明な材料が用いられた場合には、レーザ光が密封剤を透過してしまうため、密封材層の表面における反射光を得ることが難しく、密封材層１１８の高さを正確に測定することが難しいという問題があった。
　加えて、特許文献１には、このような密封剤の高さを測定又は判定することについて記載されていなかった。 Moreover, since the measurement method (3) is a destructive inspection, the reliability of the measured value is high, but there is a problem that destructive testing cannot be performed for all products.
Further, in the method (4), when a transparent material is used as the sealant, the laser light is transmitted through the sealant, so that it is difficult to obtain reflected light on the surface of the sealant layer. There is a problem that it is difficult to accurately measure the height of the sealing material layer 118.
In addition, Patent Document 1 does not describe measuring or determining the height of such a sealant.
　一方、密封剤層の高さを判定する手段として、凹部の内壁に、密封剤層の適正高さを示す目盛りを予め刻んでおく手段も考えられる。しかし、このような手段を採用した場合、目盛りを視認する角度によっては、密封剤層の上面が、内壁に刻まれた目盛りを超えているか否かを判定することが困難という問題がある。しかも、この問題は、密封剤又は密封剤層が透明であれば顕著に発現する問題である。 On the other hand, as a means for determining the height of the sealant layer, a means for preliminarily marking a scale indicating the appropriate height of the sealant layer on the inner wall of the recess may be considered. However, when such a means is adopted, there is a problem that it is difficult to determine whether or not the upper surface of the sealant layer exceeds the scale carved on the inner wall depending on the angle at which the scale is visually recognized. Moreover, this problem is a problem that appears remarkably if the sealant or the sealant layer is transparent.
　従って、本発明は上述の問題点に鑑みてなされたものであり、その目的は、コンタクト挿入孔における密閉性を確保するためにハウジングに形成された凹部に充填される密封剤の状態や透明度（透過率）にかかわらず、破壊検査することなく密封剤層の高さが適正であるか否かを容易に判定することができるコネクタを提供することにある。

　以下、本発明に係るコネクタの第１の実施形態について、図面を参照して説明する。図１は本発明に係るコネクタの第１の実施形態における斜視図である。図２は、図１における２－２線に沿う断面図である。
　図１及び図２において、コネクタ１は、絶縁性のハウジング１０と、そのハウジング１０に取り付けられる複数のピン状のコンタクト２０とを有している。 (First embodiment)
Hereinafter, a first embodiment of a connector according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a connector according to a first embodiment of the present invention. 2 is a cross-sectional view taken along line 2-2 in FIG.
1 and 2, the connector 1 includes an insulating housing 10 and a plurality of pin-shaped contacts 20 attached to the housing 10.
　ハウジング１０は、絶縁性を示す材料からなる直方体形状の部材であり、ハウジング１０の上面１０ａ及び下面１０ｂには嵌合凹部１２，１３が形成されている。
　嵌合凹部１２は、ハウジング１０の上面１０ａを基準として、その周方向に突出し、更にその周端部が立ち上げられて側壁部１２ａが形成されてなる。
　一方、嵌合凹部１３は、ハウジング１０の下面１０ｂを基準とした側周面において、その周端部が立ち上げられて側壁部１３ｂが形成されてなる。 The housing 10 is a rectangular parallelepiped member made of an insulating material, and fitting recesses 12 and 13 are formed on the upper surface 10 a and the lower surface 10 b of the housing 10.
The fitting recess 12 protrudes in the circumferential direction with respect to the upper surface 10a of the housing 10, and further, the peripheral end is raised to form a side wall 12a.
On the other hand, the fitting recess 13 has a side wall portion 13b formed by raising a peripheral end portion of the side circumferential surface with the lower surface 10b of the housing 10 as a reference.
　そして、嵌合凹部１２の底面（ハウジング１０の上面１０ａ）の中央部には、後述する密封剤が所定量充填される凹部１１が形成されている。
　また、凹部１１の底面１１ａには、凹部１１の底面１１ａ、及び嵌合凹部１３の底面１３ａを貫通する複数列状のコンタクト挿入孔１１ｂが形成されている。各コンタクト２０は、コンタクト挿入孔１１ｂに挿入されることによって、ハウジング１０に取り付けられる。 A recess 11 is formed in the center of the bottom surface of the fitting recess 12 (the upper surface 10a of the housing 10).
A plurality of rows of contact insertion holes 11 b penetrating the bottom surface 11 a of the recess 11 and the bottom surface 13 a of the fitting recess 13 are formed on the bottom surface 11 a of the recess 11. Each contact 20 is attached to the housing 10 by being inserted into the contact insertion hole 11b.
　また、凹部１１の底面１１ａにおいて、２列ずつ形成されたコンタクト挿入孔１１ｂの列間の中央部には、高さ判定部３０が設けられる。
　コンタクト２０は、細長い円柱形状をなし、ハウジング１０のコンタクト挿入孔１１ｂに挿入され、圧入固定される。また、本発明に係るコネクタ１は、コンタクト２０がハウジング１０にインサートモールドされた形態であってもよい。 In addition, on the bottom surface 11 a of the recess 11, a height determination unit 30 is provided at the center between the rows of contact insertion holes 11 b formed in two rows.
The contact 20 has an elongated cylindrical shape, is inserted into the contact insertion hole 11b of the housing 10, and is press-fitted and fixed. Further, the connector 1 according to the present invention may have a form in which the contact 20 is insert-molded in the housing 10.
　コンタクト２０の材料としては、導電性があり、所定以上の強度を有すれば、特に制限はなく、目的に応じて適宜選択することができるが、例えば、錫鍍金又は金鍍金された黄銅が用いられる。
　ここで、各コンタクト挿入孔１１ｂの径、又は開口面積は、各コンタクト２０の径、又はコンタクト２０の長手方向に直交する面における断面積よりも大に設定されている。 The material of the contact 20 is not particularly limited as long as it has electrical conductivity and has a strength of a predetermined level or more, and can be appropriately selected according to the purpose. For example, tin-plated or gold-plated brass is used. It is done.
Here, the diameter or opening area of each contact insertion hole 11 b is set to be larger than the diameter of each contact 20 or the cross-sectional area in the plane orthogonal to the longitudinal direction of the contact 20.
　本発明に係るコネクタ１は、図２に示すように、コネクタ１が取り付けられる電子機器装置２００の内部と外部との境界にハウジング１０を位置させてコネクタ１が設置される。コネクタ１の嵌合凹部１２側（電子機器装置２００の内部）においては、電子機器装置２００の内部に設置された基板２１０にコンタクト２０が取り付けられる。また、コネクタ１の嵌合凹部１３側（電子機器装置２００の外部）においては、嵌合凸部３１０が形成された雄型コネクタ３００がコンタクト２０に接続される。電子機器装置２００としては、例えばＥＣＵ（Ｅｌｅｃｔｒｏｎｉｃ　Ｃｏｎｔｒｏｌ　Ｕｎｉｔ）等が挙げられる。 As shown in FIG. 2, the connector 1 according to the present invention is installed with the housing 10 positioned at the boundary between the inside and the outside of the electronic device apparatus 200 to which the connector 1 is attached. On the fitting recess 12 side of the connector 1 (inside the electronic device apparatus 200), the contact 20 is attached to the substrate 210 installed inside the electronic apparatus device 200. Further, on the fitting recess 13 side of the connector 1 (outside the electronic device apparatus 200), the male connector 300 on which the fitting protrusion 310 is formed is connected to the contact 20. Examples of the electronic device apparatus 200 include an ECU (Electronic Control Unit).
　高さ判定部３０は、凹部１１の底面１１ａ上に形成された突起状の構造物である。
　高さ判定部３０の形状としては、コンタクト挿入孔１１ｂへのコンタクト２０の挿入、及び凹部１１への密封剤の充填を妨げず、ハウジング１０の上面１０ａの法線方向（凹部１１の底面１１ａの法線方向）から見て（以下、平面視と呼ぶ。）、少なくとも２つの高さを判定可能な形状であれば、目的に応じて適宜選択することができる。高さ判定部３０の具体的な形状としては、例えば、図１に示すように、上面の面積が異なる立方体を突起部３１，３２として複数積層させて段差部を設けた態様が挙げられる。 The height determination unit 30 is a projecting structure formed on the bottom surface 11 a of the recess 11.
The shape of the height determination unit 30 does not interfere with the insertion of the contact 20 into the contact insertion hole 11b and the filling of the sealing agent into the recess 11, and the normal direction of the upper surface 10a of the housing 10 (the bottom surface 11a of the recess 11). Any shape can be selected as appropriate according to the purpose as long as it can be determined from at least two heights when viewed from the normal direction (hereinafter referred to as a plan view). As a specific shape of the height determination unit 30, for example, as shown in FIG. 1, there is an aspect in which a plurality of cubes having different top surface areas are stacked as protrusions 31 and 32 to provide a stepped portion.
　ここで、積層された複数の突起部３１，３２のそれぞれの上面３１ａ，３２ａの高さは、凹部１１及びコンタクト挿入孔１１ｂに密封剤を充填することによって形成された密封剤層５０（図３参照）の高さに基づいて設定される。例えば、高さ判定部３０が、図１に示すような２つの立方体を突起部３１，３２の積層構造として形成された場合、適正とされた密封剤の充填量を凹部１１に充填したときの密封剤層５０の高さが、下方に位置された立方体（突起部３１）の上面３１ａと、上方に位置された立方体（突起部３２）の上面３２ａとの間の高さに設定される。ここで、本発明における密封剤層５０の高さとは、凹部１１の底面１１ａから密封剤層５０の上面５０ａまでの距離を指す。なお、密封剤層５０の適切な高さは、凹部１１の底面１１ａからの高さを予め設定しておいてもよいし、凹部１１、並びに、コンタクト挿入孔１１ｂ、及びそのコンタクト挿入孔１１ｂにコンタクト２０が挿入されたときに形成される間隙（後述）等の体積を算出し、それらの体積に基づいて決定されてもよい。また、本発明における高さ判定部３０は、一以上の段差部を有していることが特徴であり、高さの異なる上面３１ａと上面３２ａとによって段差部が構成される。 Here, the heights of the upper surfaces 31a and 32a of the plurality of stacked protrusions 31 and 32 are such that the sealant layer 50 (FIG. 3) is formed by filling the recess 11 and the contact insertion hole 11b with a sealant. Set based on the height of the reference). For example, when the height determination unit 30 is formed as a stacked structure of two cubes as shown in FIG. 1 as shown in FIG. 1, when the filling amount of the appropriate sealant is filled in the recess 11 The height of the sealant layer 50 is set to a height between the upper surface 31a of the cube (projection 31) positioned below and the upper surface 32a of the cube (projection 32) positioned above. Here, the height of the sealant layer 50 in the present invention refers to the distance from the bottom surface 11 a of the recess 11 to the top surface 50 a of the sealant layer 50. The appropriate height of the sealant layer 50 may be set in advance from the bottom surface 11a of the concave portion 11, or may be set in the concave portion 11, the contact insertion hole 11b, and the contact insertion hole 11b. A volume such as a gap (described later) formed when the contact 20 is inserted may be calculated and determined based on the volume. Moreover, the height determination part 30 in this invention is characterized by having one or more level | step-difference parts, and a level | step-difference part is comprised by the upper surface 31a and the upper surface 32a from which height differs.
　本発明に係るコネクタに用いられる密封剤としては、接着性を有し、使用時（凹部１１に充填時）において所定以下の粘度の液体状態であり、所定の条件で、液体状態から固体状態に硬化（固化）する性質を有する材料であれば、特に制限はなく、目的に応じて適宜選択することができる。密封剤の具体的な材料としては、例えば、空気中の水分によって硬化する室温効果型樹脂、加熱硬化型樹脂、紫外線硬化型樹脂、及びこれら少なくともいずれかの混合物が挙げられる。密封剤の例としては、室温効果型樹脂、加熱硬化型樹脂、紫外線硬化型樹脂のいずれかの性質を有するシリコーンが好ましい。
　密封剤は、充填時における粘度が低いことが好ましい。本発明に係るコネクタに用いられる密封剤の粘度としては、例えば、１０（Ｐａ・ｓ）以下であることが好ましい。 As the sealant used for the connector according to the present invention, it has an adhesive property and is in a liquid state having a predetermined viscosity or less during use (when filling the recess 11), and from a liquid state to a solid state under a predetermined condition. There is no particular limitation as long as the material has a property of curing (solidifying), and it can be appropriately selected according to the purpose. Specific examples of the sealant include a room temperature effect resin that is cured by moisture in the air, a heat curable resin, an ultraviolet curable resin, and a mixture of at least one of these. As an example of the sealant, silicone having any one of a room temperature effect resin, a heat curable resin, and an ultraviolet curable resin is preferable.
The sealant preferably has a low viscosity at the time of filling. The viscosity of the sealant used in the connector according to the present invention is preferably 10 (Pa · s) or less, for example.
　以上のように構成された本発明に係るコネクタにおいて、密封剤を充填する方法について以下に説明する。
　本発明に係るコネクタの凹部１１に対して密封剤を充填する方法としては、流動状態の樹脂を充填する公知の方法を採用することができる。具体的には、コンタクト挿入孔１１ｂにおいて、凹部１１側とは反対側の開口部方向に流動状態の密封剤を吸引させてもよい。
　その後、使用する密封剤の硬化条件に基づき、加熱処理、紫外線照射処理などを行って、流動状態で凹部１１に充填された密封剤を硬化させて密封剤層５０を形成する。
　ここで、上記のように凹部１１に形成された密封剤層５０の高さが適正の高さであるか否かを判定する判定方法について、図面を参照して以下に説明する。 A method for filling the sealant in the connector according to the present invention configured as described above will be described below.
As a method for filling the recess 11 of the connector according to the present invention with a sealant, a known method for filling a resin in a fluid state can be employed. Specifically, in the contact insertion hole 11b, the fluidized sealant may be sucked in the direction of the opening on the side opposite to the recess 11 side.
Thereafter, based on the curing conditions of the sealant to be used, heat treatment, ultraviolet irradiation treatment, and the like are performed, and the sealant filled in the recesses 11 is cured in a fluid state to form the sealant layer 50.
Here, the determination method which determines whether the height of the sealing agent layer 50 formed in the recessed part 11 as mentioned above is an appropriate height is demonstrated below with reference to drawings.
　なお、この判定方法は、凹部１１に密封剤を充填している途中（密封剤が液体状態）でも、凹部１１への密封剤の充填が終了し、その密封剤が硬化した後（密封剤が固体状態）でも適用することができる。
　また、この判定方法は、密封剤の透明度（透過率）などによって、機器を用いた判定方法と、目視による判定方法とを適宜使い分けて行われる。 In this determination method, even when the recess 11 is being filled with the sealant (the sealant is in a liquid state), after the filling of the sealant into the recess 11 is completed and the sealant is cured (the sealant is (Solid state) can also be applied.
This determination method is performed by appropriately using a determination method using an apparatus and a visual determination method depending on the transparency (transmittance) of the sealant.
　図３は、凹部１１に密封剤を充填したときにおける密封剤層５０の高さと、高さ判定部３０の視認状態とを示す図であり、（Ａ）は、密封剤が適正な量で充填されたときの平面図であり、（Ｂ）は、（Ａ）における３Ｂ－３Ｂ線に沿う断面図であり、（Ｃ）は、密封剤が適正量を超えた量で充填されたときの平面図であり、（Ｄ）は、（Ｃ）における３Ｄ－３Ｄ線に沿う断面図であり、（Ｅ）は、密封剤が適正な量よりも少ない量で充填されたときの平面図であり、（Ｆ）は、（Ｅ）における３Ｆ－３Ｆ線に沿う断面図である。 FIG. 3 is a view showing the height of the sealant layer 50 when the recess 11 is filled with the sealant and the visual recognition state of the height determination unit 30, and (A) is a sealant filled with an appropriate amount. (B) is a cross-sectional view taken along line 3B-3B in (A), and (C) is a plan view when the sealant is filled in an amount exceeding an appropriate amount. (D) is a cross-sectional view taken along line 3D-3D in (C), (E) is a plan view when the sealant is filled in an amount smaller than the proper amount, (F) is a sectional view taken along line 3F-3F in (E).
　ここで、図３（Ａ）乃至図３（Ｆ）においては、密封剤が適正な量であるときの密封剤層５０の高さが、下方の突起部３１の上面（以下、第１の面と呼ぶ。）３１ａと、上方の突起部３２の上面（以下、第２の面と呼ぶ。）３２ａとの間に予め設定されているものとする。
　図３（Ａ）及び図３（Ｂ）に示すように、密封剤が適正な量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第２の面３２ｂだけが明瞭に見えることとなる。これにより、凹部１１に充填された密封剤の充填量が適正であると判定される。 Here, in FIGS. 3A to 3F, the height of the sealant layer 50 when the sealant is in an appropriate amount is the upper surface of the lower protrusion 31 (hereinafter referred to as the first surface). It is assumed that it is preset between 31a and the upper surface (hereinafter referred to as the second surface) 32a of the upper protrusion 32.
As shown in FIGS. 3A and 3B, when the sealant is filled in the recess 11 with an appropriate amount, the shape of the height determination unit 30 in plan view is the second surface 32b. Only will be clearly visible. Thereby, it determines with the filling amount of the sealing agent with which the recessed part 11 was filled being appropriate.
　一方、図３（Ｃ）及び図３（Ｄ）に示すように、密封剤が適正な量よりも多い量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第２の面３２ａすら明瞭に見えることがない。これにより、凹部１１に充填された密封剤の充填量は適正な量よりも多いと判定される。
　また、図３（Ｅ）及び図３（Ｆ）に示すように、密封剤が適正な量よりも少ない量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第２の面３２ａだけでなく、第１の面３１ａも明瞭に見えることとなる。これにより、凹部１１に充填された密封剤の充填量は適正な量よりも少ないと判定される。 On the other hand, as shown in FIGS. 3 (C) and 3 (D), when the sealing agent is filled in the recess 11 in an amount larger than the appropriate amount, the shape of the height determination unit 30 in plan view is as follows. Even the second surface 32a does not appear clearly. Thereby, it is determined that the filling amount of the sealing agent filled in the concave portion 11 is larger than an appropriate amount.
Further, as shown in FIGS. 3E and 3F, when the sealant is filled in the concave portion 11 in an amount smaller than an appropriate amount, the shape of the height determination unit 30 in plan view is Not only the second surface 32a but also the first surface 31a can be clearly seen. Thereby, it is determined that the filling amount of the sealing agent filled in the concave portion 11 is smaller than an appropriate amount.
　ここで、密封剤の充填量を、平面視における高さ判定部３０の見え方によって判定するにあたっては、密封剤の透明度（透過率）によって判定方法を適宜選択することが好ましい。
　密封剤の透明度（透過率）が低い場合（着色済）であれば、第１の面３１ａ、及び第２の面３２ａが視認できるか否かによって、凹部１１に充填された密封剤の量が適正であるか否かを目視で判定することができる。 Here, when determining the filling amount of the sealant based on the appearance of the height determination unit 30 in a plan view, it is preferable to appropriately select a determination method according to the transparency (transmittance) of the sealant.
If the transparency (transmittance) of the sealant is low (colored), the amount of sealant filled in the recess 11 depends on whether the first surface 31a and the second surface 32a are visible. Whether it is appropriate or not can be determined visually.
　しかし、密封剤がほぼ透明であった場合には、密封材の透明度（透過率）が低ければ本来見えない面（図１においては面３２ａ）が視認できてしまい、適正な判定が行えないことがある。
　従って、密封剤がほぼ透明であった場合には、撮像手段及び画像処理手段を有する画像処理装置（図示せず）等を用いて、平面視での高さ判定部３０の形状を撮影し、密封剤の透過率等をパラメータとした閾値に基づいて、撮影された画像を密封剤層５０の上面と、高さ判定部３０が有する複数の高さが異なる面との位置関係が識別可能に画像処理して判定することが好ましい。 However, when the sealant is almost transparent, if the transparency (transmittance) of the sealant is low, the surface that is not originally visible (surface 32a in FIG. 1) can be visually recognized, and proper determination cannot be made. There is.
Therefore, when the sealant is almost transparent, an image processing apparatus (not shown) having an imaging unit and an image processing unit is used to photograph the shape of the height determination unit 30 in plan view, The positional relationship between the upper surface of the sealant layer 50 and the surfaces having different heights of the height determination unit 30 can be identified based on a threshold value using the transmittance of the sealant as a parameter. It is preferable to determine by image processing.
　このように、本願発明に係るコネクタは、凹部１１の底面１１ａに高さ判定部３０を設けたので、凹部１１内における密封剤の充填量が適正であるか否かが目視で判別しやすくなる。また、密封剤の透明度が低いものである場合には、その充填量が適正であるか否かが目視でより判別しやすくなる。また、密封材がほぼ透明である場合には、上述のように画像処理することによって、充填量の適正であるか否かが更に判別しやすくなる。 Thus, the connector according to the present invention is provided with the height determination portion 30 on the bottom surface 11a of the recess 11, so that it is easy to visually determine whether or not the filling amount of the sealant in the recess 11 is appropriate. . Moreover, when the transparency of the sealant is low, it becomes easier to visually determine whether or not the filling amount is appropriate. Further, when the sealing material is substantially transparent, it is easier to determine whether or not the filling amount is appropriate by performing image processing as described above.

　ここで、図６（Ａ）乃至図６（Ｆ）においては、密封剤が適正な量であるときの密封剤層５０の高さが、一方の突起部３３の上面（以下、第３の面と呼ぶ。）３３ａと、他方の突起部３４の上面（以下、第４の面と呼ぶ。）３４ａとの間に予め設定されているものとする。
　図６（Ａ）及び図６（Ｂ）に示すように、密封剤が適正な量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第４の面３４ａだけが明瞭に見えることとなる。これにより、凹部１１に充填された密封剤の充填量が適正であると判定される。 Here, in FIGS. 6A to 6F, the height of the sealant layer 50 when the sealant is in an appropriate amount is the upper surface (hereinafter referred to as a third surface) of one protrusion 33. It is assumed that it is preset between an upper surface 33a of the other projection 34 (hereinafter referred to as a fourth surface) 34a.
As shown in FIGS. 6 (A) and 6 (B), when the sealing agent is filled in the concave portion 11 with an appropriate amount, the shape of the height determination unit 30 in plan view is the fourth surface 34a. Only will be clearly visible. Thereby, it determines with the filling amount of the sealing agent with which the recessed part 11 was filled being appropriate.
　一方、図６（Ｃ）及び図６（Ｄ）に示すように、密封剤が適正な量よりも多い量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第４の面３４ａすら明瞭に見えることがない。これにより、凹部１１に充填された密封剤の充填量は適正な量よりも多いと判定される。
　また、図６（Ｅ）及び図６（Ｆ）に示すように、密封剤が適正な量よりも少ない量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第４の面３４ａだけでなく、第３の面３３ａも明瞭に見えることとなる。これにより、凹部１１に充填された密封剤の充填量は適正な量よりも少ないと判定される。 On the other hand, as shown in FIGS. 6 (C) and 6 (D), when the sealant is filled in the recess 11 in an amount larger than the appropriate amount, the shape of the height determination unit 30 in plan view is as follows.

　図７は本発明に係るコネクタの第３の実施形態における斜視図である。図８は、図７における８－８線に沿う断面図である。
　図７及び図８に示すように、凹部１１の底面１１ａにおいて、２列に形成されたコンタクト挿入孔１１ｂの間に、直方体形状の突起部３５が形成され、この突起部３５の上面３５ａと高さを異ならせた面４１ａ，４２ａを有する溝部４１，４２が突起部３５に設けられている。なお、高さの異なる上面３５ａと上面４１ａ，４２ａとによって段差部が構成される。このように、突起部３５に、その上面３５ａと高さを異ならせた面４１ａ，４２ａを有する溝部４１、４２を形成することによって、凹部１１内に密封剤が充填されることによって形成される密封剤層５０の適正な高さを精度よく判定することができる。また、溝部４１，４２が形成される分、突起部３５は比較的大きく作成されるため、凹部１１に密封剤を充填する際、突起部３５において密封剤に浸った部分の体積に相当する密封剤の量を少なくすることができ、製造コストを抑えることができる。また、突起部３５が凹部１１においてリブ形状をなすため、コネクタ１の強度を高くすることができる。 (Third embodiment)

　図１２は、凹部１１に密封剤を充填したときにおける密封剤層５０の高さと、高さ判定部３０の視認状態とを示す図であり、（Ａ）は、密封剤が適正な量で充填されたときの平面図であり、（Ｂ）は、（Ａ）における１２Ｂ－１２Ｂ線に沿う断面図であり、（Ｃ）は、コネクタ１が僅かに傾いて設置されたまま密封剤が凹部１１に充填され、密封剤が適正量を超えた量で充填されたときの平面図であり、（Ｄ）は、（Ｃ）における１２Ｄ－１２Ｄ線に沿う断面図であり、（Ｅ）は、密封剤が適正な量よりも少ない量で充填されたときの平面図であり、（Ｆ）は、（Ｅ）における１２Ｆ－１２Ｆ線に沿う断面図である。 Here, similarly to the first to third embodiments described above, also in this embodiment, the height of the sealant layer 50 formed by filling the recess 11 with the sealant is an appropriate height. A determination method for determining whether or not there is will be described below with reference to the drawings.
FIG. 12 is a diagram showing the height of the sealant layer 50 when the recess 11 is filled with the sealant and the visual recognition state of the height determination unit 30, and (A) is a sealant filled with an appropriate amount. (B) is a cross-sectional view taken along the line 12B-12B in (A), and (C) is a plan view in which the sealant is recessed 11 while the connector 1 is placed slightly inclined. And (D) is a cross-sectional view taken along the line 12D-12D in (C), and (E) is a seal when the sealant is filled in an amount exceeding an appropriate amount. It is a top view when an agent is filled with an amount smaller than an appropriate amount, and (F) is a sectional view taken along line 12F-12F in (E).
　ここで、図１２（Ａ）乃至図１２（Ｆ）においては、密封剤が適正な量であるときの密封剤層５０の高さが、異なる高さの面を有する一方の突起部３６の上面（以下、第７の面と呼ぶ。）３６ａと、異なる高さの面を有する他方の突起部３７の上面（以下、第８の面と呼ぶ。）３７ａとの間に予め設定されているものとする。なお、第７の面３６ａの高さは、第８の面３７ａ、及び第８の面３７ａ同じ高さの面を有する面（以下、第９の面３８ａと呼ぶ。）よりも低いこととする。 Here, in FIG. 12A to FIG. 12F, the height of the sealing agent layer 50 when the amount of the sealing agent is an appropriate amount is the upper surface of one protrusion 36 having surfaces with different heights. (Hereinafter referred to as the seventh surface) 36a and a preset surface between the upper surface (hereinafter referred to as the eighth surface) 37a of the other protrusion 37 having a surface with a different height. And The height of the seventh surface 36a is lower than the eighth surface 37a and the surface having the same height as the eighth surface 37a (hereinafter referred to as the ninth surface 38a). .
　図１２（Ａ）及び図１２（Ｂ）に示すように、密封剤が適正な量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第８の面３７ａ、及び第９の面３８ａが明瞭に見えることとなる。これにより、凹部１１に充填された密封剤の充填量が適正であると判定される。
　一方、図１２（Ｃ）及び図１２（Ｄ）に示すように、本発明のコネクタ１が、若干傾いた状態で設置されており、密封剤が適正な量よりも多い量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、コネクタ１が傾いた状態とされたことから、第８の面３７ａ、及び第９の面３８ａのうち、第８の面３７ａが明瞭に見えてしまっている。これにより、凹部１１に充填された密封剤の充填量が適正な量よりも多いだけでなく、コネクタ１が傾いた状態であることも判定される。 As shown in FIGS. 12A and 12B, when the sealing agent is filled in the recess 11 with an appropriate amount, the shape of the height determination unit 30 in plan view is the eighth surface 37a. , And the ninth surface 38a can be clearly seen. Thereby, it determines with the filling amount of the sealing agent with which the recessed part 11 was filled being appropriate.
On the other hand, as shown in FIGS. 12 (C) and 12 (D), the connector 1 of the present invention is installed in a slightly inclined state, and the sealant is contained in the recess 11 in an amount larger than an appropriate amount. When filled, the shape of the height determination unit 30 in plan view is that the connector 1 is in an inclined state, and therefore the eighth surface 37a of the eighth surface 37a and the ninth surface 38a. Is clearly visible. Thereby, it is determined that not only the filling amount of the sealing agent filled in the recess 11 is larger than an appropriate amount, but also that the connector 1 is tilted.
　また、図１２（Ｅ）及び図１２（Ｆ）に示すように、密封剤が適正な量よりも少ない量で凹部１１内に充填されたとき、平面視での高さ判定部３０の形状は、第８の面３７ａ、及び第９の面３８ａだけでなく、第７の面３６ａもが明瞭に見えることとなる。これにより、凹部１１に充填された密封剤の充填量は適正な量よりも少ないと判定される。
　以上、本発明の実施の形態について説明してきたが、本発明はこれに限定されずに、種々の変更、改良を行うことができる。 Also, as shown in FIGS. 12E and 12F, when the sealant is filled in the recess 11 in an amount smaller than the appropriate amount, the shape of the height determination unit 30 in plan view is In addition to the eighth surface 37a and the ninth surface 38a, the seventh surface 36a can be clearly seen. Thereby, it is determined that the filling amount of the sealing agent filled in the concave portion 11 is smaller than an appropriate amount.
As mentioned above, although embodiment of this invention has been described, this invention is not limited to this, A various change and improvement can be performed.
　例えば、高さ判定部を積層形態とした第１の実施形態と、高さの異なる複数の突起を離間させた形態とした第２の実施形態とを組み合わせてもよい。このような構成とすることにより、密封剤の高さを、より細かく判定することができると共に、密封剤の量を更に抑えることができる。 For example, you may combine 1st Embodiment which made the height determination part the lamination | stacking form, and 2nd Embodiment which made the form which spaced apart the some protrusion from which height differs. By setting it as such a structure, while being able to determine the height of a sealing agent more finely, the quantity of a sealing agent can further be suppressed.
　また、高さ判定部を構成する突起部の上面の形状は、平坦面でなく、半球形状でもよい。突起部の形状を半球形状とすることにより、密封剤の高さを、平面視において大きさが連続的に識別可能な円形状で把握することができる。従って、より高精度な判定に好適である。なお、突起部の形状を半球形状とした場合には、目視による判定ではなく、機器による判定を行うことが好ましい。
　更に、特許文献１に開示されたように、コンタクト挿入孔に、ピン状のコンタクトが挿入された際に、そのコンタクト挿入孔の内周面と、ピン状のコンタクトの外周面との間に間隙を形成してもよい。 In addition, the shape of the upper surface of the projecting portion constituting the height determination unit may be a hemispherical shape instead of a flat surface. By making the shape of the protruding portion hemispherical, the height of the sealant can be grasped in a circular shape whose size can be continuously identified in plan view. Therefore, it is suitable for more accurate determination. In addition, when making the shape of a projection part into a hemispherical shape, it is preferable to perform determination by an apparatus instead of visual determination.
Further, as disclosed in Patent Document 1, when a pin-shaped contact is inserted into the contact insertion hole, a gap is formed between the inner peripheral surface of the contact insertion hole and the outer peripheral surface of the pin-shaped contact. May be formed.
