Weipu Connectors Empower Spanish Professional Football Stadium: TYP & WY Series Dual Solutions Solve Outdoor Lighting and Audio Connection Challenges

I. Client Background: Venue Upgrade Needs Focused on Professional Matches

The Spanish client of this cooperation is a well-known local sports venue facility integrator with 15 years of experience in the stadium supporting field. It has participated in the equipment upgrade projects of multiple La Liga training bases and has strict requirements on product reliability and compliance. The professional football stadium undertaken this time is located near Barcelona, Spain, with a total construction area of about 28,000 square meters and a capacity of 12,000 spectators. It is positioned as the home stadium for regional leagues and a youth football training base, and plans to be equipped with UEFA-standard HD broadcast-level lighting systems and surround sound systems.

The client clearly stated at the Munich Fair that in some previous outdoor venue projects, the insufficient waterproof performance of connectors had caused lighting short circuits during the rainy season, and connector loosening had been caused by audio vibration. These issues not only increased maintenance costs but also affected the normal operation of matches. Therefore, this project put forward "zero-tolerance" requirements for the connector's waterproof rating, anti-vibration capability, and installation and maintenance convenience, while complying with EU CE certification and local Spanish electrical standards.

II. Cooperation Process: Full-Link Communication from Initial Contact to Solution Implementation

1. Initial Contact at the Exhibition, Accurate Demand Matching: At the October 2023 Munich International Electronic Fair, the client was attracted by Weipu's outdoor waterproof connector demonstration device—staff immersed the TYP Series connector in water, and it still achieved stable current transmission. During in-depth communication, the Weipu technical team demonstrated the quick-plug structure of the TYP connector and the buckle-locking function of the WY Series on the spot in combination with the client's stadium project scenario, initially gaining the client's trust. Both parties agreed to conduct special solution communication after the exhibition.

2. Demand Decomposition, Customized Solution: After the exhibition, Weipu established a special team to address the three core needs put forward by the client one by one: For outdoor waterproof needs, it was clarified that all connectors must reach IP67 or above; for the problem of audio vibration and loosening, the connection locking structure was optimized; for maintenance convenience, tool-free installation and visual status identification were designed. Finally, a combined solution of "TYP Series for lighting power supply + WY Series for audio connection" was formed, and a detailed installation diagram and technical parameter comparison table were provided.

3. Sample Verification, Consolidating Cooperation Foundation: In November 2023, Weipu sent customized samples to Spain, including TYP 400A connectors, WY24 buckle-type connectors, and supporting waterproof electrical boxes. The client conducted three core tests: immersing the samples in 1-meter-deep water for 30 minutes, and no abnormalities were found in the power-on test after taking them out; installing the WY24 connectors on the audio simulation vibration platform, and no loosening occurred after 24 hours of continuous operation under 50Hz high-frequency vibration; realizing the plugging and unplugging of the TYP connector within 10 seconds with a special tool, meeting the demand for quick maintenance. The sample test pass rate was 100%, and both parties formally signed the procurement contract.

4. Performance Guarantee and Synchronous Technical Support: In January 2024, all products were produced and passed EU CE certification, and shipped to Spain in batches. Weipu arranged 2 technical engineers to provide on-site installation guidance, offered accurate installation suggestions for the installation environments of different areas of the stadium (such as lighting on the top of the stands and audio around the lawn), and conducted a 1-day operation training for the client's construction team to ensure that maintenance personnel could independently complete the inspection, repair and replacement of connectors in the later period.

III. Product Details: Dual-Series Connectors Solve Core Pain Points

1. TYP Series 400A High-Current Waterproof Connector: Builds a "Protective Wall" for Lighting Power Supply

The stadium lighting system needs to drive more than 200 HD broadcast-level LED lights at the same time, with a single light power of 1500W, and the total current demand exceeds 350A. All power supply nodes are exposed outdoors, facing the challenges of rain, dust, and day-night temperature differences. Weipu TYP Series 400A connectors address three key issues:

Waterproof Performance: Adopting a double-sealing structure, with aging-resistant silicone sealing rings at the interface. Combined with the IP68 protection design of the waterproof electrical box, it forms a double waterproof barrier of "connector + electrical box". Even in the heavy rain of the Spanish Mediterranean climate, it can avoid short-circuit faults caused by water intrusion.

High-Current Carrying Capacity: The conductor is made of brass material, with silver-plated treatment to reduce contact resistance. It can stably carry a rated current of 400A, and the short-term overload current reaches 600A, fully meeting the instantaneous current demand when the lighting system starts. The conductor heat dissipation structure is optimized, and the surface temperature does not exceed 60℃ after 8 hours of continuous operation.

Maintenance Convenience: Adopting a quick-plug connection design, equipped with a visual locking ring. When the connector is fully locked, the locking ring changes from red to green, allowing maintenance personnel to quickly confirm the connection status. At the same time, it supports live plugging and unplugging, enabling replacement without power failure in emergency situations, reducing the risk of match interruption.

2. WY24 Series Buckle-Type Waterproof Connector: Solves the "Loosening Problem" Caused by Audio Vibration

The stadium's surround sound system is equipped with 80 sound units, distributed under the stands and around the stadium. It generates high-frequency vibrations of 50-200Hz during operation, which easily causes pin contact failure or overall loosening of ordinary connectors. Weipu WY24 Series connectors achieve a breakthrough through structural innovation:

Anti-Vibration Design: Adopting a high-strength buckle-locking structure. The buckle automatically pops open to complete rigid locking after the connector is inserted, with a locking force of 150N. After the simulated audio vibration test, the contact resistance change rate is less than 5% after 1000 hours of continuous vibration, which is far better than the industry standard, completely solving the loosening problem caused by high-frequency vibration.

Waterproof and Weather Resistance: With an IP67 waterproof rating, it can resist rain splashing and humid environment erosion. The shell is made of flame-retardant PA66 material, with a temperature resistance range of -40℃ to 120℃, which can adapt to the outdoor environment of high temperature in summer and low temperature in winter in Spain, avoiding performance degradation caused by material aging.

Strong Compatibility: Supports multi-core wire connection, which can transmit power and audio signals at the same time, reducing the number of connectors used. The interface adopts a standardized design, which can be directly adapted to the European brand audio purchased by the client without additional connector replacement, reducing project modification costs.
