Usage Guide

1.Preparation

Mini Waterproof Gel-box can be wiring with our CMK Series Connectors:

Prepare the Wire:Remove the insulation layer of the wire to the length required by the CMK connector. It is recommended to attach an insulating sleeve at the end before connecting to ensure a stable and reliable connection and to prevent the wire from being damaged.
Complete the Electrical Connection:Insert the prepared wire completely into the CMK quick connector terminal until a “click” sound is heard, indicating a proper connection. Gently pull on the wire to ensure it is securely fixed and will not come loose.

2.Assembling the Gel-box

Open the Gel-box:Locate the locking mechanism on the side of the gel container. Press firmly inward on the designated area to release the latch, and then open the lid.
Place the Connector: Place the pre-assembled CMK connector component into the bottom of the gel box, making sure it is neatly positioned within the groove.
Close and Seal: Align the lid with the base, then press firmly until you hear or feel a distinct “click”. This indicates that the lid is fully locked and the sealing process is complete.

3.Important Note

Gel Displacement: After closing the lid, you will notice some gel overflowing from the sealing edge. This is a normal phenomenon. It indicates that the gel has fully filled all the internal voids and has exerted sufficient pressure, thus forming a complete waterproof barrier.

4.Final Check

Before deployment, visually inspect the assembly to ensure the Gel-box is securely locked with no gaps, and that the CMK connector is properly seated inside. This ensures the IP68 waterproof rating is fully achieved.

How It Achieves Superior Waterproofing (The “Gel-Sealing” Advantage)

Pre-filled, Self-Adaptive Gel:
The core of our technology is a special non-toxic dielectric gel with a unique formula. When the box is closed, this gel moves and covers the entire connector and wire interface, filling every tiny gap and cavity. It forms a barrier that effectively blocks water, moisture, and contaminants.
IP68 Rated Mechanical Seal:
This gel works in conjunction with a precisely designed polycarbonate casing. The sturdy lid is equipped with an integrated locking mechanism. When the locking device is activated, it compresses into an internal gel reservoir. This dual sealing system ensures a complete and permanent airtight seal, reaching the industry-leading IP68 level, suitable for continuous underwater immersion.
Validated by Rigorous Testing:
This design is not just theoretical. Each batch of material undergoes strict testing, including long-term immersion in deep water, exposure to extreme temperature cycles, and pressure tests. This rigorous verification process ensures that this mini waterproof gel box can fulfill its promise, achieving flawless and long-lasting waterproof performance in your most critical applications.

The Working Principle

In summary, the working principle of the Mini Waterproof Gel Box is:
It creates an overall sealed device by using its pre-filled adaptive gel (which automatically releases when closed to wrap the connection area, effectively filling all gaps and forming a seamless, self-healing barrier that is waterproof and resistant to contaminants).
With its compact, impact-resistant polycarbonate casing and integrated locking mechanism, it provides robust physical protection. This mechanism achieves guaranteed IP68 sealing by mechanically compressing the gel.
By completely isolating the connection area from the environment, it ensures long-term electrical integrity. The dielectric gel prevents corrosion and poor contact, while the sturdy casing prevents physical damage and UV degradation.

This is an extremely simple sealing device. Its unique gel technology and dual sealing design enable permanent connections in the most demanding humid and harsh environments, with extremely high reliability.

FAQ for Ceramics Barrier Terminal Block

What is the core advantage of the "Gel-Sealing" technology?

The core lies in its pre-filled, self-adaptive dielectric gel. Upon closing the housing, the gel is precisely displaced to envelop the entire connector and wire interfaces, automatically filling every microscopic gap. This creates a seamless, self-healing barrier that actively blocks moisture, water, and contaminants, ensuring a permanent seal even under thermal cycling and vibration.

What does the IP68 rating mean in practical use?

The IP68 rating represents the highest level of dust and water ingress protection. For our product, it certifies that the Gel-box, when properly closed and locked, can withstand continuous submersion in water under specified conditions (typically beyond 1 meter depth) without any moisture penetration, making it ideal for permanent underwater and underground applications.

What are the critical precautions during installation?

Two points are crucial:

Installation Temperature Range: All wiring and assembly must be performed within an ambient temperature range of -40°C to 50°C. Operating outside this range can compromise the gel’s viscosity and sealing performance.
Single-Use Seal: The unit is designed as a permanent seal. Once the lid is closed and locked, it must not be reopened. Reopening will permanently disrupt the gel seal and invalidate the waterproof integrity.

How does it compare to traditional methods like heat-shrink tubing or tape?

It offers superior reliability and ease of use. Traditional methods rely heavily on installer skill and are less effective against long-term water pressure and chemical exposure. Our Gel-box provides a foolproof solution by combining a robust physical housing with advanced gel technology, delivering standardized IP68 performance, longer service life, and minimal maintenance.

Gel is displaced and seeps out after closing. Is this normal?

Yes, this is a completely normal and intentional phenomenon. It confirms that the internal gel has adequately filled all voids and is exerting sufficient pressure to form a complete waterproof barrier. Simply ensure the lid is fully locked; no further action is needed.

What are its typical application scenarios?

It is engineered for harsh environments, including:

Permanent Submersion: Underwater lights, fountains, and pond pumps.
Demanding Outdoor Use: Solar panel junction boxes, outdoor CCTV cameras, and architectural lighting connections.
Corrosive Atmospheres: Agricultural greenhouses, coastal facilities, and industrial sites with exposure to chemicals or oils.
Underground & Infrastructure: Direct-burial cable splices and traffic signal systems.

Does the gel have a shelf life? Will it harden or degrade?

No. Our specialized dielectric gel is formulated to remain permanently soft and non-hardening, with no specified shelf life. It will maintain its adaptive and self-healing properties throughout the product’s entire service life, ensuring consistent waterproof protection.

Operating and Safety Instructions

To ensure the long-term reliability and waterproof performance of the Mini Waterproof Gel Box, please strictly follow the following guidelines when installing and using it:

Note on Installation Temperature: Assembly and wiring operations should be carried out within the environmental temperature range of -40°C to 50°C. Operating beyond this range may affect the viscosity and sealing performance of the gel, thereby reducing the final waterproof effect.
Power-off during Installation: Ensure that the power is completely disconnected during all wiring operations to avoid electrical safety hazards.
Avoid Repeated Opening: Once the gel box is closed and sealed, do not open it again. Repeated opening will permanently damage the gel seal and destroy its waterproof performance. This device is designed for single use and has a permanent sealing function.
Ensure Firm Installation of Connectors: Before closing the lid, make sure that the pre-connected connectors are correctly placed in the grooves and will not interfere with the lid’s closure.
Keep the Sealed Surface Clean: Before final assembly, check the gel surface and the sealing edges of the housing to ensure they are free of dust, debris, or any contaminants that may hinder a perfect seal.
