Description

Technical Field

[0001] The present application relates to the field of electromechanical components, and specifically to a 5-core plug-in high-voltage sealed connector cable assembly. More specifically, the present application provides a plug-in high-voltage sealed connector cable assembly, which is suitable for tubular specific equipment with a large aspect ratio and has good high-voltage sealing performance. Background Art

[0002] In recent years, existing sealed connector cable assemblies have been widely used in electrical signal transmission in various projects. The typical structure of a sealed connector cable assembly is composed of a socket, a plug and a cable; among them, the plug and the socket are mainly composed of a socket shell, a pin, a jack, a sealing ring, a cable and a connecting sleeve, and the structural parts are assembled to form a whole. The sealing methods used in sealed connector cable assemblies mainly include shell plus O-ring sealing, packing sealing, etc. At present, when multi-core plugs are docked, a positioning guide structure must be set to prevent fooling. When docking, it has a unique directionality, and blind insertion and rotational straight insertion cannot be achieved, and the sealing requirements are relatively low.

[0003] For multi-core plugs, the contact layout of the typical structure is generally reflected on the plug-in projection surface, and the contacts are arranged in a matrix or circle. Taking 5-core as an example, Figure 1 The typical contact layout and fool-proof design of multi-core plugs are given.

[0004] Based on the structural characteristics of the sealed connector cable assembly, its typical structure is as follows: the pin is a rigid solid cylindrical conductor, and the socket is an elastic sleeve structure; the contacts with the same load use the same nominal diameter, such as Figure 2 shown.

[0005] However, existing sealed connector cable assemblies cannot meet the requirements for installation in specific equipment, nor can they achieve blind insertion or direct insertion under certain harsh working conditions of high-humidity and high-pressure mud, nor can they meet the requirements of high-pressure sealing at 3,500 meters underground.

[0006] Therefore, there is an urgent need for a new device to meet the use requirements of tubular specific equipment with a large aspect ratio (aspect ratio greater than 30). Summary of the invention

Fig.11 B is a schematic diagram of the structure of the male central catheter.

[0057] As mentioned above, the harsh working conditions of high humidity and high pressure mud put forward higher requirements on the structure and materials. To this end, the present application provides a 5-core direct plug-in high-voltage sealed connector cable assembly, which structurally solves the shortcomings of the prior art, solves the connection problem of cables under special working conditions, and realizes reliable electrical connection, which is completely different from the connector in the conventional sense. The 5-core direct plug-in high-voltage sealed connector cable assembly of the present application is composed of a male plug-in assembly, a connecting cable, and a female plug-in assembly. The male plug-in assembly is arranged as a 5-core coaxial line. The male plug-in assembly, the connecting cable, and the female plug-in assembly are integrally vulcanized and formed into an integrated structure and cannot be disassembled.

[0058] One end of the connecting cable is a male plug assembly, and the other end of the connecting cable is a female plug assembly. The male plug assembly is composed of 5 male elastic springs with different diameters (i.e., the first male elastic spring to the fifth male elastic spring) arranged axially on the same axis at a certain electrical gap distance; the female plug assembly is composed of 5 female circular rings with different diameters (i.e., the fifth female circular ring to the first female circular ring) arranged axially on the same axis at a certain electrical gap distance; at the same time, the male plug assembly is connected to the connecting cable through a male conductor connector, and the female plug assembly is connected to the connecting cable through a female conductor connector (i.e., the fifth female conductor connector to the first female conductor connector).

[0059] The male plug assembly is pressed into an integrated structure through the male plug insulation connector, and the female plug assembly is pressed into an integrated structure through the female plug insulation connector. Each interface can block the high-humidity and high-pressure mud from the outside. At the same time, the male plug assembly forms an integrated O-ring insulation sealing structure (i.e. the male plug insulation connector part between two adjacent male plug fixing rings) on the plug-in surface through the male plug insulation connector; after plugging, each level of contact can be blocked from the external high voltage. In this structure, the male plug insulation connector is used to form a rubber arc convex ring structure (similar to an O core ring), thereby ensuring the sealing of the plug-in surface of the contact.

[0060] Figure 7 A comparison diagram of the existing 5-core contact layout and the 5-core contact layout in Example 1 is given. Figure 7 A is the existing 5-core contact layout diagram. Figure 7 B is the layout diagram of the 5-core contacts in Example 1. Figure 7 As shown in B, the 5-core contacts of the present application adopt a linear layout on the same axis, which solves the problem that the existing structure has directional uniqueness and cannot be rotated for blind insertion, and can realize 360° rotation and insertion of the 5 contacts on the axis.

[0061] Furthermore, the male component of the present application adopts a drum spring elastic pin design, the drum spring is detachable, and the female component adopts a rigid sleeve structure. The use of this structure solves the problem of on-site flushable and replaceable contacts. At the same time, in order to ensure the current carrying capacity of each contact, 3 150A and 2 15A, ensure that each level of contact contacts are in contact step by step, ensure the necessary electrical clearance, and each pair of contacts has different diameters and lead ends for easy plugging.

[0062] Furthermore, the connector cable assembly of the present application does not require guidance or directionality when plugged in, and can be rotated for straight plugging and blind plugging. In the present application, the connector cable assembly adopts an overall vulcanized seal, and the male head of the plug assembly and the connecting cable, and the female head of the plug assembly and the connecting cable are not removable, so that it has better sealing. In the present application, the male head of the plug assembly, the female head of the plug assembly, the connecting cable, the male head insulating connector, and the female head insulating connector are integrally vulcanized to form an integral male and female plug double-headed cable assembly-high-voltage wet joint. All the joint surfaces of the parts in the connector cable assembly are bonded without gaps and leakage channels, ensuring good sealing performance.

[0063] Furthermore, when the connector cable assembly of the present application is used, the male head of the plug-in assembly and the female head of the plug-in assembly do not need to identify the angle when plugging together. They can rotate 360 ​​degrees and be inserted directly at any angle without identifying the direction. When in use, multiple connector cable assemblies are connected end to end, so that power and signals can be transmitted to hundreds of meters or even thousands of meters underground. Affected by the structure of the tubular short section, the connector cable assembly is fixedly installed inside the tubular short section and cannot be rotated or bent. It can move forward and backward with the external tubular short section, driving the internal male head of the plug-in assembly and the female head of the plug-in assembly to achieve end-to-end connection.

[0064] In this example, the main function of the connector is to transmit three-phase AC motor power and two-phase DC communication signals at the same time.

[0065] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
