Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly relates to a waterproof hot pressing process for deep - water connectors and deep - water connectors. Background Art

[0002] In the field of water - borne and underwater charged products, such as water bicycles, underwater thrusters, underwater robots and other water entertainment products and industrial - grade products, the performance of deep - water connectors is crucial. Currently, these products often experience water leakage and failure due to the bonding problem between the injection - molded housing of the deep - water connector and the wire. In the existing market, various bonding processes are used for the injection - molded housing and wire of deep - water connectors. Most of the connectors bond the tail of the wire to the housing through adhesives to achieve waterproof connection.

[0003] This adhesive - based connection method requires surface treatment, roughening treatment, cleaning and degreasing of the wire substrate before operation, then applying adhesive, and then injection - molding or vulcanization. However, the underwater environment is extremely complex. The product is soaked and pressured in water for a long time and is also affected by salt spray corrosion and mold erosion. Under the combined action of these factors, the adhesive is extremely prone to cracking and failure, which in turn leads to the loss of the waterproof function of the electrical connector, seriously affecting the normal use and safety of the product.

[0004] With the increasing demand for water - applied products, the performance requirements for deep - water connector harness assemblies are becoming more and more stringent. How to safely and quickly connect the power supply and transmit signals has become the key to the development of water - borne products. Driven by this, researchers have started to explore new connection technologies, and the hot pressing technology for injection - molded housing and wire has become the research focus, aiming to solve the defects of the existing adhesive connection method. Summary of the Invention

[0005] To overcome the above - mentioned deficiencies in the prior art, the purpose of the present invention is to disclose a waterproof hot pressing process for deep - water connectors and deep - water connectors.

[0006] The present invention discloses a waterproof hot pressing process for deep - water connectors, including the following steps: Step 1: Prepare an injection - molded housing and a wire, and assemble the injection - molded housing and the wire to form a pre - component; Step 2: Prepare two sets of oppositely arranged hot - pressing electrode blocks, and connect the two sets of hot - pressing electrode blocks to a pulse hot - pressing device; Step 3: Place the pre - component between the two sets of hot - pressing electrode blocks, such that the connection part of the injection - molded housing and the wire corresponds to the two sets of hot - pressing electrode blocks; Step 4: Start the pulse hot - pressing device and control the hot - pressing electrode blocks to move towards each other and squeeze to the connection part of the injection - molded housing and the wire, and melt the injection - molded housing and the wire into an integral waterproof structure through overall heating.

[0007] Preferred technical solution: The inner sides of the two groups of hot-pressing electrode blocks are both configured as arc surface structures that fit the connection between the injection molded housing and the wire, and multiple groups of annular ridges or annular grooves are formed on the surface of the arc surface structure.

[0008] Preferred technical solution: The two groups of hot-pressing electrode blocks are controlled to approach and separate by a pressing mechanism.

[0009] Preferred technical solution: It further includes an infrared temperature sensor, which is used to detect the temperature at the connection between the injection molded housing and the wire during the hot-pressing process.

[0010] A deep-water electrical connector adopts the above-mentioned waterproof hot-pressing process for deep-water electrical connectors.

[0011] Due to the application of the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows: The present invention adopts a hot-pressing process to melt the injection molded housing and the wire into an integral waterproof structure by means of overall heating, achieving a permanent bonding effect. Compared with the traditional connection method using adhesives, it completely avoids the cracking phenomenon caused by factors such as the adhesives being soaked, pressed, corroded by salt spray, and eroded by mildew in a complex underwater environment, greatly improving the waterproof performance of the deep-water electrical connector and ensuring the safety and stability of the charged products above and below water during use.
