Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cable technology, and in particular to a double-sealed explosion-proof cable joint for ultrasonic cleaning devices. Background Technology

[0002] Ultrasonic cleaning devices are widely used in industrial, medical, and laboratory fields as highly efficient cleaning equipment. Their working principle utilizes high-frequency ultrasonic waves to create cavitation in the cleaning fluid, thereby cleaning the workpiece. These devices typically operate in humid environments, and may even contain flammable or explosive gases; therefore, the safety and sealing requirements for their electrical components are extremely high.

[0003] As a critical connecting component for power transmission, the performance of cable connectors directly affects the safe and stable operation of the entire device. Existing cable connectors generally suffer from the following defects: First, their sealing structure is relatively simple, typically relying on a single sealing ring for static sealing. This ring is prone to failure under long-term vibration, temperature changes, or installation stress, allowing moisture, dust, or corrosive gases to enter the enclosure, leading to short circuits, component corrosion, and other malfunctions. Second, in the high-frequency mechanical vibration environment unique to ultrasonic cleaning devices, the connection between traditional connectors and cables is prone to loosening, creating gaps and compromising the sealing effect. Third, in explosion-proof applications, a single sealing structure is insufficient to effectively isolate potential electrical sparks generated inside the enclosure from the external explosive environment, posing a safety hazard.

[0004] Therefore, there is an urgent need in this field for a reasonably designed, reliably sealed cable connector that is especially adaptable to high-frequency vibration environments and has explosion-proof capabilities, in order to ensure the safe and long-term operation of ultrasonic cleaning devices and other similarly harsh operating conditions. Utility Model Content

[0005] In view of this, it is necessary to provide a double-sealed explosion-proof cable connector for ultrasonic cleaning devices, so as to at least solve the problem that the existing cable connectors for ultrasonic cleaning devices in the related technology have a relatively simple sealing structure, usually relying on a single sealing ring for static sealing, which is prone to failure under long-term vibration, temperature difference changes or installation stress, resulting in water vapor, dust or corrosive gases entering the inside of the casing, causing circuit short circuits, component corrosion and other faults.

[0006] This application provides a double-sealed explosion-proof cable connector for an ultrasonic cleaning device, comprising: a connector body, a sealing ring assembly, a waterproof connector, and a waterproof pipe. The connector body includes a first connector, a clamping nut, and a second connector. One end of the first connector is mounted on the chassis of the ultrasonic cleaning device, and the other end of the first connector is screwed into one end of the clamping nut. A receiving cavity is provided between the first connector and the waterproof connector, and the waterproof connector is housed within the receiving cavity. The other end of the clamping nut is screwed into one end of the second connector, and the other end of the second connector is fixedly connected to the waterproof pipe. The sealing ring assembly includes a first sealing ring and a second sealing ring. The first sealing ring is sleeved on one end of the first connector, and the second sealing ring is sleeved on one end of the second connector. The first connector and the chassis of the ultrasonic cleaning device are sealed together by the first sealing ring; the first connector and the clamping nut are sealed together by the waterproof connector; and the second connector and the clamping nut are sealed together by the second sealing ring.

[0007] In one embodiment, one end of the first connector is provided with a first threaded head, the first sealing ring is sleeved on the first threaded head, the first threaded head is provided with an outwardly arranged first external thread, the chassis of the ultrasonic device is provided with a cable outlet hole, the cable outlet hole is provided with an inwardly arranged first internal thread; wherein, the first threaded head is screwed into the first internal thread of the cable outlet hole through the first external thread and is sealed and connected by the first sealing ring.

[0008] In one embodiment, the other end of the first connector is provided with a second threaded head, and one end of the clamping nut is provided with a second internal thread; wherein the second threaded head is screwed into the second internal thread of the clamping nut through the second external thread.

[0009] In one embodiment, one end of the waterproof connector is embedded in the port of the second threaded head, one end of the clamping nut is provided with an inclined pressure ring, and the other end of the waterproof connector is received in the clamping nut and abuts against the ring surface of the inclined pressure ring; wherein, the inclined pressure ring is used to abut against the waterproof connector and tighten it, and the waterproof connector is used to seal and fix the cable flowing out of the outlet hole.

[0010] In one embodiment, one end of the second connector is provided with a third threaded head, and the second sealing ring is sleeved on the third threaded head. The third threaded head is provided with an outwardly arranged third external thread, and the other end of the clamping nut is provided with an inwardly arranged third internal thread. The third threaded head is screwed into the third internal thread through the third external thread and sealed by the second sealing ring.

[0011] In one embodiment, the sealing ring assembly further includes a third sealing ring, through which the waterproof pipe and the second connector are sealed together. Beneficial effects

[0012] Compared with the prior art, the double-sealed explosion-proof cable connector for ultrasonic cleaning devices provided by the present invention has the following significant advantages: 1. Multiple seals, high reliability: This invention creatively employs a multi-stage, multi-type sealing combination. A static seal is achieved between the connector and the chassis via a first sealing ring; a dynamic clamping seal is achieved on the cable passing through the connector via a waterproof connector that can be compressed and contracted by the inclined pressure ring of the clamping nut, effectively preventing seal failure due to cable movement; a second sealing ring provides another layer of static seal between the second connector and the clamping nut. This multi-seal structure constitutes an extremely reliable sealing system, greatly improving overall dustproof, waterproof (e.g., up to IP68 rating), and explosion-proof performance.

[0013] 2. Excellent vibration resistance: This connector structure is specifically designed for the high-frequency vibration environment of ultrasonic cleaning equipment. The components are primarily connected by threads, resulting in a compact and robust structure. In particular, the waterproof connector maintains a tight grip on the cable under the continuous pressure of the clamping nut, effectively mitigating the effects of vibration, preventing loosening of the connector and the formation of sealing gaps, and ensuring durable sealing under long-term vibration conditions.

[0014] 3. Modular design for convenient installation and maintenance: The entire connector is modularly assembled from several main components, including the first connector, clamping nut, and second connector. The structure is clear, and the assembly sequence is well-defined. During on-site installation or subsequent maintenance, simply tighten the threaded connections in sequence to compress all sealing surfaces at once. The installation process is simple and quick, and the sealing elements are easy to disassemble and replace, reducing maintenance costs. Attached Figure Description
