Description
本発明は、挿入されたプラグとの電気的接続を行うジャックに関する。 The present invention relates to a jack for making an electrical connection with an inserted plug.
レーザ光を吸収する熱可塑性樹脂からなる第１樹脂部材と、レーザ光を透過する熱可塑性樹脂からなる第２樹脂部材とを接触させ、この第２樹脂部材側からレーザ光を照射して、この両部材の接触界面をレーザ溶着することによって製造されてなる樹脂接合体の製造方法が知られている。 A first resin member made of a thermoplastic resin that absorbs laser light is brought into contact with a second resin member made of a thermoplastic resin that transmits laser light, and laser light is irradiated from the second resin member side. There is known a method for producing a resin joined body produced by laser welding the contact interface between both members.
特許文献１に、第２樹脂部材が強化繊維を含有して射出成形で形成されたものである場合には、その第２樹脂部材の成形に用いられた金型のゲート（キャビティに隣接して連なる加熱された原料樹脂の注入口）の近傍に、含有されている強化繊維の分布が局部的に異なるレーザ光低透過性部位を形成できることが記載されている。 In Patent Document 1, when the second resin member contains reinforcing fibers and is formed by injection molding, the gate of the mold used for molding the second resin member (adjacent to the cavity) It is described that a laser beam low-transmittance region having a locally different distribution of reinforcing fibers can be formed in the vicinity of the continuous heated raw material resin inlet).
図７は特許文献１の樹脂接合体１００を示す平面図である。図７では、ケース本体１１０（第１樹脂部材）に蓋１２０（第２樹脂部材）を、レーザ光低透過性部位Ｌ１のＳ２を始点として左回りに１周してＳ２に至り、さらにＦ２までレーザ光を照射してレーザ溶着する。 FIG. 7 is a plan view showing the resin joined body 100 of Patent Document 1. FIG. In FIG. 7, the lid 120 (second resin member) is placed on the case main body 110 (first resin member), and the S1 of the laser light low-transmitting portion L1 is made one turn counterclockwise to reach S2, and further up to F2. Laser welding is performed by laser irradiation.
こうして、レーザ光低透過性部位Ｌ１を、他の溶着部位１１１より１回多くレーザ光の照射を受けて溶着される溶着オーバラップ部位１１２とすることによって、ボイドが発生して接合力（溶着強度）が低下したり、再度の加熱、溶融、冷却によってシール性が不安定になったりするといった問題が回避できるとされている。 In this way, the laser light low-permeability portion L1 is made the welding overlap portion 112 that is welded by being irradiated with laser light once more than the other welding portions 111, thereby generating voids and bonding strength (welding strength). ) Can be avoided, and problems such as unstable sealing due to reheating, melting, and cooling can be avoided.
しかしながら、金型のゲート位置や、第２樹脂部材に含有させる強化繊維の分量等を変更すると、レーザ光低透過部位における透過量も異なってしまうため、溶着オーバラップ部位を適切な透過量にコントロールすることは難しい。そのため、２回のレーザ光照射では溶着不十分になる場合もあり、また２回のレーザ光照射では溶着過多になって、接合力が低下したり、シール性が不安定になったりする場合もあり、溶着不良を効果的に防止することができなかった。 However, if the gate position of the mold or the amount of reinforcing fiber contained in the second resin member is changed, the amount of transmission at the laser light low transmission portion will also differ, so the welding overlap portion is controlled to an appropriate transmission amount. Difficult to do. For this reason, welding may be insufficient when the laser beam is irradiated twice, and excessive welding may occur when the laser beam is irradiated twice, resulting in a decrease in bonding force or unstable sealing performance. In addition, poor welding could not be effectively prevented.
本発明は、上述した課題を解決するもので、充填材を含有する合成樹脂がレーザ溶着され、且つ、溶着不良を効果的に防止することができるジャックを提供することを目的とする。 The present invention solves the above-described problems, and an object of the present invention is to provide a jack in which a synthetic resin containing a filler is laser welded and can effectively prevent poor welding.
本発明のジャックは、収納空間の周囲を囲む壁部を有し、光吸収材料からなる下側ハウジングと、
前記収納空間の上部を塞ぐ天板部を有し、光透過材料からなり、前記天板部の周縁部が前記下側ハウジングの前記壁部にレーザ溶着される上側カバーと、
前記下側ハウジングの内外を連通するように前記下側ハウジングに取り付けられた導電端子と、を備えるジャックであって、
前記上側カバーは、充填材を含有する合成樹脂からなり射出成形により形成され、前記射出成形のゲート跡を前記天板部の前記周縁部を避けた位置に有し、前記上側カバーの前記天板部は、下側の面から前記収納空間に向かって下方に突出する突出部を備え、
前記ゲート跡は、前記突出部の位置の上方であって、前記天板部の上側の面に設けられたことを特徴とする。
The jack of the present invention has a wall portion surrounding the storage space, a lower housing made of a light absorbing material,
An upper cover having a top plate portion that closes an upper portion of the storage space, made of a light transmitting material, and a peripheral portion of the top plate portion laser welded to the wall portion of the lower housing;
A conductive terminal attached to the lower housing so as to communicate between the inside and the outside of the lower housing,
The upper cover is made of a synthetic resin containing a filler, is formed by injection molding, has a gate mark of the injection molding at a position avoiding the peripheral edge of the top plate portion, and the top plate of the upper cover The portion includes a protruding portion that protrudes downward from the lower surface toward the storage space,
The gate mark is provided on the upper surface of the top plate portion above the position of the protruding portion .
この構成によれば、上側カバーに、充填材を含有する合成樹脂を用いることによって強度を高めることができ、且つ、天板部の周縁部にレーザ光低透過部位が現れないので、溶着不良を効果的に防止することができ、また、前記上側カバーの前記天板部は、下側の面から前記収納空間に向かって下方に突出する突出部を備え、前記ゲート跡は、前記突出部の位置の上方であって、前記天板部の上側の面に設けられたことにより、突出部が設けられた部分は肉厚となっており、この突出部の上方に位置するように射出成型の金型のゲートを設けると、ヒケやソリの発生を抑制することができる。 According to this configuration, the strength can be increased by using a synthetic resin containing a filler for the upper cover, and the laser light low transmission portion does not appear in the peripheral portion of the top plate portion. In addition, the top plate portion of the upper cover includes a protruding portion that protrudes downward from the lower surface toward the storage space, and the gate mark is formed on the protruding portion. By being provided on the upper surface of the top plate portion above the position, the portion provided with the protruding portion is thick, and injection molding is performed so as to be positioned above the protruding portion.

本発明の実施形態のジャック１は、図１〜図６に示すように、下側ハウジング１１と上側カバー１２と導電端子１３とキャップ１４とを備えている。ジャック１は、図示しないプラグが挿入可能な収納空間１ａを有しており、挿入されたプラグとの電気的接続が行われる。 As shown in FIGS. 1 to 6, the jack 1 according to the embodiment of the present invention includes a lower housing 11, an upper cover 12, a conductive terminal 13, and a cap 14. The jack 1 has a storage space 1a into which a plug (not shown) can be inserted, and is electrically connected to the inserted plug.
なお、以下の説明においては、図１のＺ１側を上側、Ｚ２側を下側、Ｙ１側を前側、Ｙ２側を後側とする。これは説明を分かりやすくするためであり、ジャック１の使用時の方向を限定するものではない。 In the following description, the Z1 side in FIG. 1 is the upper side, the Z2 side is the lower side, the Y1 side is the front side, and the Y2 side is the rear side. This is for ease of explanation, and does not limit the direction in which the jack 1 is used.
下側ハウジング１１は、合成樹脂を主成分とする光吸収材料からなる。例えば、黒色に着色されたナイロン樹脂を使用することができる。ナイロン樹脂は、適度な加熱で成形することができ、また、ナイロン樹脂は着色用の顔料を多く含有している場合は光吸収性を有している。下側ハウジング１１は、図２に示すように、収納空間１ａの周囲を囲む壁部１１ａと底部１１ｂを有し、上方に解放された形状である。壁部１１ａの上側は平坦に加工されている。また、下側ハウジング１１は、壁部１１ａ及び底部１１ｂの前側に配置されたフランジ部１１ｃを備えている。 The lower housing 11 is made of a light absorbing material whose main component is synthetic resin. For example, a black nylon resin can be used. Nylon resin can be molded by moderate heating, and the nylon resin has light absorption when it contains a lot of pigments for coloring. As shown in FIG. 2, the lower housing 11 has a wall portion 11 a and a bottom portion 11 b surrounding the storage space 1 a and has a shape opened upward. The upper side of the wall portion 11a is processed flat. The lower housing 11 includes a flange portion 11c disposed on the front side of the wall portion 11a and the bottom portion 11b.
導電端子１３は、導電性の金属で形成され、下側ハウジング１１の壁部１１ａ及び底部１１ｂに、図２に示すように、下側ハウジング１１の内外を連通するように取り付けられている。より具体的には、導電端子１３は、インサート成形によって下側ハウジング１１に一体化されている。導電端子１３には、例えば、燐青銅を使用することができる。導電端子１３は、収納空間１ａに図示しないプラグが挿入されたときにプラグの電極面に当接するように、可動接点部１３ａを備えている。可動接点部１３ａの一部は、インサート成形後に導電端子１３と係合させることによって取り付けられている。なお、下側ハウジング１１への導電端子１３の固定方法は、インサート成形に限定されず、例えば接着材等によって一体化させてもよい。 The conductive terminal 13 is formed of a conductive metal, and is attached to the wall 11a and the bottom 11b of the lower housing 11 so as to communicate the inside and outside of the lower housing 11 as shown in FIG. More specifically, the conductive terminal 13 is integrated with the lower housing 11 by insert molding. For example, phosphor bronze can be used for the conductive terminal 13. The conductive terminal 13 includes a movable contact portion 13a so as to come into contact with the electrode surface of the plug when a plug (not shown) is inserted into the storage space 1a. A part of the movable contact portion 13a is attached by engaging with the conductive terminal 13 after insert molding. The method of fixing the conductive terminal 13 to the lower housing 11 is not limited to insert molding, and may be integrated by, for example, an adhesive material.
上側カバー１２は、機械的な強度を向上するための充填材を含有する合成樹脂からなり、射出成形により形成されている。この合成樹脂には、例えば、乳白色のナイロン樹脂を使用することができる。ナイロン樹脂は、適度な加熱で成形することができ、また、顔料を含有していない場合には乳白色で透光性を有している。また、充填材には、ガラスファイバーを使用することができる。ガラスファイバーを充填材とすることにより、機械的な寸法安定性が向上し、機械的強度や表面硬度が向上する。なお、これらの下側ハウジング１１に用いられている材料は、レーザ光を透過可能な光透過材料であるが、充填材の含有量によって光学的な特性が変化し、例えばレーザ光透過量が変化する。 The upper cover 12 is made of a synthetic resin containing a filler for improving mechanical strength, and is formed by injection molding. As this synthetic resin, for example, a milky white nylon resin can be used. Nylon resin can be molded by moderate heating, and when it does not contain a pigment, it is milky white and translucent. Moreover, a glass fiber can be used for a filler. By using glass fiber as a filler, mechanical dimensional stability is improved, and mechanical strength and surface hardness are improved. The material used for the lower housing 11 is a light transmissive material that can transmit laser light. However, the optical characteristics change depending on the filler content, for example, the laser light transmission amount changes. To do.
上側カバー１２は、図２及び図５に示すように、天板部１２ａと、前側に配置されたフランジ部１２ｃとを備えている。上側カバー１２は、天板部１２ａの周縁部１２ｂが平坦な面に加工されており、周縁部１２ｂの上下方向の厚さが均一になっている。また、天板部１２ａの上側の面１２ｆには、図２に示すように、ゲート跡１２ｄが形成されている。このゲート跡１２ｄは、射出成形の金型に設けられたゲート位置に対応して形成されるものであり、本実施形態では天板部１２ａの周縁部１２ｂを避けた位置に設けられている。さらに、上側カバー１２は、収納空間１ａに挿入されるプラグをガイド可能なガイド部１ｂとして、図５及び図６に示すように、天板部１２ａの下側の面１２ｇから収納空間１ａに向かって下方に突出する突出部１２ｅを備えている。 As shown in FIGS. 2 and 5, the upper cover 12 includes a top plate portion 12 a and a flange portion 12 c disposed on the front side. As for the upper cover 12, the peripheral part 12b of the top-plate part 12a is processed into the flat surface, and the thickness of the up-down direction of the peripheral part 12b is uniform. Further, as shown in FIG. 2, a gate mark 12d is formed on the upper surface 12f of the top plate portion 12a. This gate mark 12d is formed corresponding to the gate position provided in the injection mold, and is provided at a position avoiding the peripheral edge 12b of the top plate 12a in this embodiment. Further, the upper cover 12 serves as a guide portion 1b capable of guiding a plug inserted into the storage space 1a from the lower surface 12g of the top plate portion 12a toward the storage space 1a as shown in FIGS. And a projecting portion 12e projecting downward.
キャップ１４は、合成樹脂を主成分とする光吸収材料からなる。例えば、黒色に着色されたナイロン樹脂を使用することができる。ナイロン樹脂は、適度な加熱で成形することができ、また、ナイロン樹脂は着色用の顔料を多く含有している場合は光吸収性を有している。キャップ１４は、図２に示すように、筒状に設けられた開口部１４ａを有し、その後側に配置されたフランジ部１４ｃと、さらに後側に突出した突起部１４ｂを備えている。 The cap 14 is made of a light absorbing material whose main component is synthetic resin. For example, a black nylon resin can be used. Nylon resin can be molded by moderate heating, and the nylon resin has light absorption when it contains a lot of pigments for coloring. As shown in FIG. 2, the cap 14 has an opening 14 a provided in a cylindrical shape, and includes a flange portion 14 c disposed on the rear side and a projection portion 14 b protruding further on the rear side.
上側カバー１２は、下側ハウジング１１の上側を覆うように取り付けられる。天板部１２ａの周縁部１２ｂが下側ハウジング１１の壁部１１ａに当接するように載置され、上方から周縁部１２ｂに沿ってレーザ光が照射されることによって、上側カバー１２が下側ハウジング１１に溶着される。周縁部１２ｂの厚さが一定に形成されているので、下側ハウジング１１の壁部１１ａと上側カバー１２とのレーザ溶着を安定におこなうことができる。一方、キャップ１４は、突起部１４ｂが下側ハウジング１１の壁部１１ａ及び底部１１ｂの内面に沿って挿入されるようにして、下側ハウジング１１の前側に取り付けられ、下側ハウジング１１及び上側カバー１２に接合される。例えば、固定用冶具を用いてキャップ１４を下側ハウジング１１及び上側カバー１２に圧接して、超音波溶着される。なお、超音波溶着等の溶着を用いずに、例えば接着材等によって接合させてもよい。 The upper cover 12 is attached so as to cover the upper side of the lower housing 11. The peripheral portion 12b of the top plate portion 12a is placed so as to contact the wall portion 11a of the lower housing 11, and the upper cover 12 is attached to the lower housing by being irradiated with laser light along the peripheral portion 12b from above. 11 is welded. Since the peripheral edge portion 12b is formed with a constant thickness, laser welding between the wall portion 11a of the lower housing 11 and the upper cover 12 can be performed stably. On the other hand, the cap 14 is attached to the front side of the lower housing 11 such that the protruding portion 14b is inserted along the inner surface of the wall portion 11a and the bottom portion 11b of the lower housing 11, and the lower housing 11 and the upper cover are attached. 12 is joined. For example, the cap 14 is pressed against the lower housing 11 and the upper cover 12 using a fixing jig, and ultrasonic welding is performed. In addition, you may join by an adhesive etc., without using welding, such as ultrasonic welding.
これにより、本実施形態のジャック１は、開口部１４ａから収納空間１ａに浸入した水が開口部１４ａ以外に漏れ出てこない状態に保持される。スマートフォン等の屋外で使用する機会の多い携帯型電子機器には防水性を備えることが要求されており、本実施形態のジャック１はこのような用途に適している。 Thereby, the jack 1 of this embodiment is hold | maintained in the state which the water which permeated into the accommodation space 1a from the opening part 14a does not leak out except the opening part 14a. Portable electronic devices that are frequently used outdoors such as smartphones are required to be waterproof, and the jack 1 of this embodiment is suitable for such applications.
次に、図５及び図６を参照して、本実施形態のジャック１の特徴について詳述する。 Next, the features of the jack 1 of the present embodiment will be described in detail with reference to FIGS.
本実施形態のジャック１における上側カバー１２は、天板部１２ａの下側の面１２ｇにガイド部１ｂとして突出部１２ｅを備え、この突出部１２ｅの位置に合わせて、天板部１２ａの上側の面１２ｆにゲート跡１２ｄが設けられている。前述したように、ゲート跡１２ｄは、射出成形の金型に設けられたゲート位置に対応して形成されるものである。 The upper cover 12 in the jack 1 of the present embodiment includes a protruding portion 12e as a guide portion 1b on the lower surface 12g of the top plate portion 12a. The upper cover 12 on the upper side of the top plate portion 12a is aligned with the position of the protruding portion 12e. A gate mark 12d is provided on the surface 12f. As described above, the gate mark 12d is formed corresponding to the gate position provided in the injection mold.
ガイド部１ｂとしての突出部１２ｅは、図示しないプラグの外形に合わせた凹形状になっている。なお、天板部１２ａの下側の面１２ｇは、突出部１２ｅの前側もプラグの外形に合わせた凹形状を有し、プラグの挿入をガイドするようになっている。 The protruding portion 12e as the guide portion 1b has a concave shape matching the outer shape of a plug (not shown). The lower surface 12g of the top plate portion 12a has a concave shape that matches the outer shape of the plug on the front side of the protruding portion 12e, and guides the insertion of the plug.
ガイド部１ｂは、プラグ形状に合わせた形状であるため、図示しないプラグが収納空間１ａに挿入されるときに、傾いた状態で挿入されないようにプラグの挿入を補助する。ガイド部１ｂが設けられていない場合には、プラグが傾いた状態で挿入されたときなどに導電端子１３の可動接点部１３ａが想定量以上に押し込まれてしまう不具合を生じるが、ガイド部１ｂが設けられていれば、そのような不具合が防止される。これにより、導電端子１３を保護することができる。また、プラグがガイド部１ｂに当接することによって、プラグの反対側の面と導電端子１３の可動接点部１３ａとの接触を安定に保持させることができる。 Since the guide portion 1b has a shape that matches the plug shape, when a plug (not shown) is inserted into the storage space 1a, the guide portion 1b assists the insertion of the plug so that it is not inserted in an inclined state. In the case where the guide portion 1b is not provided, there is a problem that the movable contact portion 13a of the conductive terminal 13 is pushed more than expected when the plug is inserted in an inclined state. If provided, such a malfunction is prevented. Thereby, the conductive terminal 13 can be protected. Further, the contact of the plug with the guide portion 1b makes it possible to stably maintain the contact between the opposite surface of the plug and the movable contact portion 13a of the conductive terminal 13.
本実施形態では、ガイド部１ｂを突出部１２ｅによって形成しているので、別部材を追加することなく、ガイド部１ｂを設けることが可能である。この構造を利用して、特別に突出部を設けないようにしたので、収納空間１ａ内に障害物が形成されることを防止することができる。 In this embodiment, since the guide part 1b is formed by the protrusion part 12e, it is possible to provide the guide part 1b without adding another member. Since this structure is used so that the protrusion is not provided, it is possible to prevent an obstacle from being formed in the storage space 1a.
上側カバー１２は、天板部１２ａの厚さを薄くしても必要な機械的強度を有するように、充填材を含有する合成樹脂が射出成形されている。射出成形では、溶解した合成樹脂を加熱した金型内に射出して冷却するので、取り出された成形品は溶けた合成樹脂の状態と較べて収縮する。そのため、成形品は金型の内面そのままの形状とはならず、へこんだり、穴が開いてしまったりする。この収縮による不良をヒケと呼ぶ。また、薄板状の成形品では、不均一な収縮によってソリを生じることがある。このため、ヒケやソリの発生を抑制するように工夫しなければならない。天板部１２ａの肉薄部分に位置するように射出成形の金型にゲートを設けると、樹脂の流動性が悪くなり、ヒケやソリが発生しやすくなるという問題がある。本実施形態のジャック１では、突出部１２ｅが設けられた部分は肉厚となっており、この突出部１２ｅの上方に位置するように金型のゲートを設けると、ヒケやソリの発生を抑制することができる。 The upper cover 12 is injection-molded with a synthetic resin containing a filler so as to have the necessary mechanical strength even if the top plate portion 12a is thinned. In the injection molding, the melted synthetic resin is injected into a heated mold and cooled, so that the molded product taken out contracts compared to the melted synthetic resin. For this reason, the molded product does not have the shape of the inner surface of the mold as it is, but is dented or has a hole. A defect due to this contraction is called sink. Further, in a thin plate-shaped molded product, warping may occur due to non-uniform shrinkage. For this reason, it must be devised to suppress the occurrence of sink marks and warps. If a gate is provided in an injection mold so as to be located in the thin portion of the top plate portion 12a, there is a problem that the fluidity of the resin is deteriorated and sinking or warping is likely to occur. In the jack 1 of this embodiment, the portion provided with the protruding portion 12e is thick, and if a mold gate is provided so as to be positioned above the protruding portion 12e, the occurrence of sink marks and warpage is suppressed. can do.
また、充填材での反射等によって、充填材を含有する合成樹脂のレーザ光透過量が変化することが見出された。例えば、充填材にガラスファイバーを用いると、ガラスファイバーでの反射が大きくなって、レーザ光透過量が低下する。射出成形の金型のゲートに近い領域では、他の領域に比べてより多くの充填材が蓄積されることが知られている。このため、例えば、充填材としてガラスファイバーを含有する合成樹脂の場合、ゲート跡１２ｄに近い領域では、局所的にレーザ光透過量が低下する。天板部１２ａの周縁部１２ｂは、レーザ光が照射されることによって下側ハウジング１１に溶着される領域であるため、局所的にレーザ光透過量が低下することがあれば、溶着不良を生じやすくなる。このため、周縁部１２ｂは、レーザ光透過量が一定になっていることが好ましい。 Further, it has been found that the amount of laser light transmitted through the synthetic resin containing the filler changes due to reflection on the filler. For example, when glass fiber is used as the filler, reflection on the glass fiber increases, and the amount of laser beam transmission decreases. It is known that more filler is accumulated in a region near the gate of an injection mold than in other regions. For this reason, for example, in the case of a synthetic resin containing glass fiber as a filler, the amount of laser beam transmission locally decreases in a region close to the gate mark 12d. Since the peripheral edge portion 12b of the top plate portion 12a is a region welded to the lower housing 11 when irradiated with laser light, if the amount of laser light transmission decreases locally, poor welding occurs. It becomes easy. For this reason, it is preferable that the peripheral part 12b has a constant laser beam transmission amount.
本実施形態のジャック１では、ゲート跡１２ｄが天板部１２ａの周縁部１２ｂを避けた位置に設けられている。このため、その射出成形に使用されている合成樹脂がレーザ光透過量の変化を生じる充填材を含有していても、天板部１２ａの周縁部１２ｂにレーザ光低透過部位が現れない。このため、本実施形態のジャック１では、周縁部１２ｂのレーザ光透過量が一定になっている。 In the jack 1 of this embodiment, the gate mark 12d is provided at a position avoiding the peripheral edge 12b of the top plate 12a. For this reason, even if the synthetic resin used for the injection molding contains a filler that causes a change in the amount of laser light transmission, a laser light low transmission portion does not appear on the peripheral edge portion 12b of the top plate portion 12a. For this reason, in the jack 1 of this embodiment, the laser beam transmission amount of the peripheral part 12b is constant.
上述したように、天板部１２ａの周縁部１２ｂは、レーザ光透過量が一定であるので、レーザ溶着に最適なレーザ光の照射量を一定にでき、レーザ溶着が安定する。また、局所的にレーザ光を２回照射するような溶着方法を必要としないので、２回の加熱、冷却に伴う溶着不良を引き起こす心配がない。 As described above, since the peripheral portion 12b of the top plate portion 12a has a constant laser beam transmission amount, the laser beam irradiation amount optimum for laser welding can be made constant, and the laser welding becomes stable. Further, since there is no need for a welding method in which the laser beam is locally irradiated twice, there is no fear of causing poor welding due to twice heating and cooling.
以下、本実施形態としたことによる効果について説明する。 Hereinafter, the effect by having set it as this embodiment is demonstrated.
本実施形態のジャック１は、光吸収材料からなる下側ハウジング１１と、光透過材料からなり、天板部１２ａの周縁部１２ｂがレーザ溶着される上側カバー１２と、下側ハウジング１１の内外を連通するように取り付けられた導電端子１３と、を備える。上側カバー１２は、レーザ光透過量の変化を生じる充填材を含有する合成樹脂からなり射出成形により形成され、射出成形のゲート跡１２ｄを天板部１２ａの周縁部１２ｂを避けた位置に有している。 The jack 1 according to the present embodiment includes a lower housing 11 made of a light absorbing material, an upper cover 12 made of a light transmitting material and having a peripheral edge 12b of the top plate 12a welded thereto, and the inside and outside of the lower housing 11. And a conductive terminal 13 attached so as to communicate. The upper cover 12 is made of a synthetic resin containing a filler that causes a change in the amount of transmitted laser light, is formed by injection molding, and has an injection molded gate mark 12d at a position avoiding the peripheral edge 12b of the top plate 12a. ing.
この構成によれば、上側カバー１２に、充填材を含有する合成樹脂を用いることによって強度を高めることができ、且つ、レーザ光透過量の変化を生じる充填材を含有していても天板部１２ａの周縁部１２ｂにレーザ光低透過部位が現れないので、溶着不良を効果的に防止することができる。 According to this configuration, the upper cover 12 can be increased in strength by using a synthetic resin containing a filler, and the top plate portion even if it contains a filler that causes a change in the amount of laser light transmission. Since a laser beam low transmission part does not appear in the peripheral part 12b of 12a, the welding defect can be prevented effectively.
また、本実施形態のジャック１において、上側カバー１２の天板部１２ａは、下側の面１２ｇから収納空間１ａに向かって下方に突出する突出部１２ｅを備え、ゲート跡１２ｄは、突出部１２ｅの位置の上方であって、天板部１２ａの上側の面１２ｆに設けられた。 Further, in the jack 1 of the present embodiment, the top plate portion 12a of the upper cover 12 includes a protruding portion 12e that protrudes downward from the lower surface 12g toward the storage space 1a, and the gate mark 12d includes the protruding portion 12e. The upper surface 12f of the top plate portion 12a is provided above the position of the top plate portion 12a.
天板部１２ａの肉薄部分に位置するように射出成形の金型にゲートを設けると、樹脂の流動性が悪くなり、ヒケやソリが発生しやすくなるという問題があるが、突出部１２ｅが設けられた部分は肉厚となっており、この突出部１２ｅの上方に位置するように金型のゲートを設けると、ヒケやソリの発生を抑制することができる。 If the injection mold is provided with a gate so that it is located in the thin portion of the top plate portion 12a, the fluidity of the resin is deteriorated, and sinking and warping are likely to occur. However, the protrusion 12e is provided. The formed portion is thick, and if a mold gate is provided so as to be positioned above the protruding portion 12e, the occurrence of sink marks and warpage can be suppressed.
また、本実施形態のジャック１において、突出部１２ｅは、収納空間１ａに挿入されるプラグをガイド可能なガイド部１ｂである。 Moreover, in the jack 1 of this embodiment, the protrusion part 12e is the guide part 1b which can guide the plug inserted in the storage space 1a.
この構成によれば、プラグの挿入を補助するガイド部１ｂを設けているので、導電端子１３を保護することができる。この構造を利用して、特別に突出部を設けないようにしたので、収納空間１ａ内に障害物が形成されることを防止することができる。 According to this configuration, since the guide portion 1b that assists the insertion of the plug is provided, the conductive terminal 13 can be protected. Since this structure is used so that the protrusion is not provided, it is possible to prevent an obstacle from being formed in the storage space 1a.
以上のように、本発明の実施形態のジャック１を具体的に説明したが、本発明は上記の実施形態に限定されるものではなく、要旨を逸脱しない範囲で種々変更して実施することが可能である。例えば次のように変形して実施することができ、これらも本発明の技術的範囲に属する。 As mentioned above, although the jack 1 of embodiment of this invention was demonstrated concretely, this invention is not limited to said embodiment, It can implement variously in the range which does not deviate from a summary. Is possible. For example, the present invention can be modified as follows, and these also belong to the technical scope of the present invention.
（１）本実施形態において、ゲート跡１２ｄに近い領域ではレーザ光透過量が低下するとしたが、レーザ光透過量が大きくなる場合でも同様に作用する。合成樹脂及び充填材の種類によって、充填材の含有量が多い方が、レーザ光透過量が大きい場合もある。この場合には、金型のゲートに近い領域では、レーザ光透過量が多くなって、加熱され過ぎることにって溶着不良を引き起こす。したがって、この場合でも、射出成形のゲート跡１２ｄを天板部１２ａの周縁部１２ｂを避けた位置に有していることは有効である。 (1) In the present embodiment, the laser beam transmission amount decreases in the region near the gate trace 12d, but the same effect is obtained even when the laser beam transmission amount increases. Depending on the type of synthetic resin and filler, there are cases where the amount of laser light transmitted is larger when the filler content is larger. In this case, in the region close to the gate of the mold, the amount of transmitted laser light increases, and overheating causes a welding failure. Therefore, even in this case, it is effective to have the injection-molded gate mark 12d at a position avoiding the peripheral edge portion 12b of the top plate portion 12a.
（２）本実施形態において、ガイド部１ｂを突出部１２ｅによって形成しているが、突出部１２ｅとガイド部１ｂとを別々に設けるようにしてもよい。また、ガイド部１ｂは１箇所に限定されるものではなく、複数箇所に設置するようにしてもよい。 (2) In the present embodiment, the guide portion 1b is formed by the protruding portion 12e, but the protruding portion 12e and the guide portion 1b may be provided separately. Moreover, the guide part 1b is not limited to one place, You may make it install in multiple places.
（３）本実施形態において、キャップ１４を超音波溶着等で接合するとしたが、上側カバー１２と一体で透光性材料によって形成し、下側ハウジング１１にレーザ溶着する構造にしてもよい。 (3) In the present embodiment, the cap 14 is joined by ultrasonic welding or the like. However, the cap 14 may be formed of a translucent material integrally with the upper cover 12 and laser welded to the lower housing 11.
