How do you prevent water ingress at cable entry points?

Cable entries use sealed glands with rubber grommets positioned at the bottom or side as specified, combined with internal drip channels to route condensation away from equipment.

製品概要

これらの金属製筐体は、セキュリティ監視、ネットワーク通信、弱電流配線システム向けに特別に設計された屋外用保護筐体です。ポールに取り付けられたカメラ接続ボックス、防水ネットワークキャビネット、配線分配ボックス、電気端子筐体などが含まれます。回路基板、電源アダプタ、スイッチ、配線端子、監視機器などを雨、埃、紫外線、破壊行為から保護し、道路監視、地域セキュリティ、公園監視、工場周辺警備、屋外通信配線プロジェクトなどに幅広く活用されています。

当社が解決したコア処理上の課題（当社の独自の競争優位性）

キャビネットの曲げ変形とフレームの歪みを解決しました

大型薄板筐体はCNC曲げ加工後に反りやすく、ドアの閉まりが悪くなる原因となります。当社では、曲げスプリングバック補正金型と多点位置決め成形プロセスを採用することで、筐体フレームの平面度と直線度を確保し、ドアと筐体本体間の隙間を厳密な公差内に制御しています。
IP防水性能に影響を与える縫い目のずれを解消

切断ムラや組み立てのずれは、屋外用途において水漏れのリスクを高めます。当社では、レーザー精密ブランキング加工と溶接後研削仕上げを採用し、お客様のご要望に合わせたシリコン製シーリング溝を正確に加工することで、長期間の屋外設置後も安定したIP54/IP65の防水性能を保証します。
ポール取り付けブラケットの固定穴位置オフセット

ポールクランプブラケットの取り付け穴は位置ずれを起こしやすく、現場でのポール設置が困難になる場合があります。当社では一体型パンチング治具を採用することで、穴ピッチの一貫性を確保し、二次的な穴あけ調整なしで丸型・角型ポールへの迅速な取り付けを実現しました。
塗膜のムラと屋外での耐腐食性の低さを解消

通常の表面処理では、長時間の直射日光や雨による浸食で剥がれや錆が発生します。当社では、徹底的な脱脂、リン酸塩処理による前処理に加え、均一な粉体塗装を施し、エッジと溶接部の被覆を強化することで、優れた耐塩水噴霧性と10年以上の屋外耐用年数を実現しています。

当社の工場の中核となる強み

社内一貫体制の板金加工

レーザー切断、CNC曲げ加工、溶接、研削、タッピング、シール溝加工、粉体塗装など、完全に独立した工程により、外部委託は一切行わず、コスト管理の向上、リードタイムの短縮、そして完全な生産トレーサビリティを実現しています。
成熟したセキュリティエンクロージャーのカスタマイズ経験

監視・通信業界向け屋外電気キャビネットの設計・製造において豊富な経験を持ち、IP防水構造設計、ポールマウント組立構造、内部配線レイアウトに精通しており、組立不良率およびアフターサービス不良率を低減するための専門的なDFM最適化提案を提供できます。
厳格なバッチ一貫性品質管理

初回品検査、工程内寸法検査、完成品の防水・密封性サンプリング検査をすべての注文に対して実施し、量産時の寸法変動を効果的に回避し、大規模なセキュリティエンジニアリングプロジェクトへの安定した長期納品を実現します。
柔軟なOEMおよびODMカスタマイズサービス

材質（SPCC、SGCC、ステンレス鋼、アルミニウム合金）、筐体サイズ、ドア構造、ポール取り付け方法、内部仕切り、ケーブル引き込み口、IP等級、表面コーティングはカスタマイズ可能です。レーザー刻印によるブランドロゴや、パーソナライズされたパッケージもご用意できます。

適用シーン

道路交通監視システム、住宅地セキュリティ監視、景勝地および公園監視、工場周辺警報システム、屋外無線通信配線、街路灯微弱電流配電、建設現場の一時的な電気保護。
