What is a Prototype Cable ?
Prototype cable assemblies are the first samples produced after initial design completion, used for early device interconnection and testing. They enable you to test, evaluate, and optimize your product before full-scale production. Prototype samples play a crucial role in transforming your design concepts from blueprints into tangible products.
JinHai provides prototyping services for consumer electronics, road vehicles, public lighting infrastructure, industrial machinery, and medical devices, ensuring your prototype testing delivers reliability and precision.

Custom Wire Harness
Unveiling Our Range of Custom Wire Harnesses and Components
Waterproof USB Solutions
These cable assemblies consist of tinned copper stranded wire, waterproof connectors, and shielding layers, offering waterproof ratings ranging from IPX4 to IPX8. They support either direct plug-and-play or magnetic snap-on installation methods. All assemblies are rated for up to 10,000 insertion cycles. Additionally, they feature 24 pins compatible with various video and audio signal output protocols.
Flexible Wiring Harness Solutions
FFC cable assemblies are copper wires bonded together to form a cable, providing a wire-to-PCB connection method. This connection is particularly suitable for transmitting power or signals in dynamic environments, such as medical electronic devices, access control systems, and smart printers.
This type of cable utilizes flexible spring wire, allowing for flexible extension, retraction, and coiling. It is particularly suitable for mobile medical devices.
High precision, real-time performance, and interference resistance are core requirements for patient monitoring equipment. JinHai employs premium materials and precision manufacturing to ensure this wiring harness meets industry standards and your specific needs.
75-Ohm RF Cable Assembly
This type of cable assembly delivers stable high-frequency signal transmission characteristics and is primarily used in satellite television, video surveillance systems, and professional video interface transmission in studio applications.
Marine Trailer Wiring Harness
It features a waterproof male connector and multiple branches, suitable for trailers ranging from standard to high-end models. JinHai also provides customized solutions for ATV trailers, flatbed trailers, and other specialized trailer applications.
Quality and Safety, Guaranteed
Adhering to IPC/WHMA-A-620 standards, we ensure reliability and performance in each product.
What Our Customer Say
What is the delivery time for custom orders?
Regarding order lead times, JinHai will clearly communicate order quantities and determine lead times based on different order volumes.
Below are the lead times JinHai can accommodate for different order quantities:
1. Small-batch custom orders (50–500 pieces): Due to the smaller order size and the need to procure many raw materials on the spot, the pre-production preparation time is longer. Therefore, the typical lead time is 2–4 weeks.
2. Large-batch custom orders (over 1,000 units): Due to the large order volume and significant raw material requirements, some materials are sourced from distributors. This necessitates adjusting allocation ratios or requires factory time for inventory checks. Therefore, the typical order cycle ranges from 8 to 20 weeks. Additionally, the cycle may extend due to special circumstances (such as shipping weather conditions or tariff fluctuations).
What types of connectors does JinHai offer?
One of JinHai’s most competitive areas:
- Automotive connectors (terminal connectors such as JST, TE, MOLEX, etc.; high-voltage connectors; high-speed data connectors; RF connectors)
- Consumer electronics connectors (board-to-board connectors; wire-to-board connectors; FPC/FFC connectors; I/O connectors; battery connectors)
- Industrial connectors (circular connectors M series, rectangular connectors Harting Han series, aviation connectors, and terminal blocks)
