Description

Technical Field

[0001] This invention relates to a high-stability high-voltage connector for use in 10kV high-voltage transmission lines. Background Technology

[0002] With the development of shore power, ports, ships and other related departments have put forward new requirements for shore power, prompting the continuous upgrading of shore power equipment.

[0003] Traditional shore power connectors can only realize the normal function of power transmission between ships and shore. Currently, data communication between ships and shore relies on radio communication. However, due to the significant interference from the ship's hull, data transmission is greatly limited; moreover, the installation and location selection of radio communication terminals are cumbersome. Therefore, a connector that can realize both power transmission and data communication between ships and shore has practical significance and value.

[0004] As is well known, ships sailing at sea face harsh environments with high humidity and strong salt spray corrosion. Therefore, the requirements for connectors used on ships are relatively high. However, ordinary connectors, in addition to the above-mentioned disadvantages, also have problems such as poor connection stability, weak shock absorption, and complex structure manufacturing, making it difficult to meet the requirements for use on ships. Therefore, a high-stability high-voltage connector for 10kV high-voltage transmission lines has emerged. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-stability high-voltage connector for use in 10kV high-voltage transmission lines.

[0006] A high-stability high-voltage connector for 10kV high-voltage transmission lines includes a socket, pins, and a plug. The socket and plug are connected by a flange. The socket has three inner insulating tubes inside, which sequentially pass through a sealing gasket and an inner limiting fixing plate installed inside the socket. One end of each inner insulating tube is inserted into the inner insertion end of the pin. A retaining ring is fitted at the insertion point of the inner insulating tube and the pin. The outer insertion end of the pin is inserted into the three outer insulating tubes inside the plug. A power spring is provided on the inner wall of each pin insertion point. The three outer insulating tubes extend to the outside of the outer limiting fixing plate. Telescopic cable ties for securing the outer and inner insulating tubes are installed on the outer walls of both the outer and inner limiting fixing plates.

[0007] As a further improvement, the outer walls of the socket and plug are both covered with a shell to protect them from seawater salt spray corrosion, extend their service life, and reduce the impact of harsh marine environments on the connectors.

[0008] As a further improvement, the outer shell is made of stainless steel, which has high corrosion resistance and can be used in harsh environments. It also has fire resistance, low temperature resistance and heat resistance, can resist scaling and maintain strength at high temperatures.

[0009] As a further improvement, the sealing gasket, inner limiting fixing plate, and outer limiting fixing plate are all made of insulating materials. Most of these insulating materials are resistant to chemical corrosion, have excellent insulation and electrical resistance, are lightweight, easy to use, easy to process and manufacture, and are inexpensive.

[0010] As a further improvement, the sidewall of the sealing gasket is provided with a shock-absorbing groove.

[0011] As a further improvement, the inside of the damping groove is equipped with hexagonal bolts that connect to the flange. The damping groove on the sealing gasket and the hexagonal bolts work together to limit and dampen vibration. It has good heat treatment performance, high elastic limit, impact toughness, and fatigue limit, which improves the durability and stability of the internal components of the entire connector, prevents vibration and impact, reduces vibration frequency, and extends service life.

[0012] Beneficial effects:

[0013] This device utilizes a multi-layered shock absorption structure to make the internal structure of the connector more stable and has a certain degree of sealing. The connection structure consists of simple mechanical structures, which are easy to install, have a long service life, and are not easily damaged. It is suitable for harsh marine environments and solves the problems of high humidity and strong salt spray corrosion. It has strong adaptability to the operating environment and strong shock absorption effect, which not only makes the connection effect of the entire connector better, but also makes the internal stability of the connector stronger and more reliable in use.

[0014] This device uses an outer casing to protect the socket and plug, isolating them from seawater salt spray corrosion, extending the service life of the socket and plug, and reducing the impact of harsh marine environments on the connectors.

[0015] The sealing gasket in this device has excellent heat treatment performance, high elastic limit, impact toughness, and fatigue limit, which improves the durability and stability of the internal components of the connector, prevents vibration and impact, reduces vibration frequency, and extends service life.

[0016] In addition to overcoming the shortcomings of ordinary connectors, this device also features stable connection, strong shock absorption, simple structure and manufacturing, and small footprint, meeting the requirements for shipboard use and suitable for harsh environments. It is also fire-resistant, low-temperature resistant and heat-resistant, can resist scaling and maintain strength at high temperatures. Attached Figure Description

[0023] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0024] like Figures 1-5 The following is a specific embodiment of the present invention: a high-stability high-voltage connector for 10kV high-voltage transmission lines, comprising a housing 1, a flange 2, an inner insulating tube 3, a retaining ring 4, a pin 5, a power spring 6, a telescopic cable tie 7, an outer insulating tube 8, an inner limiting fixing plate 9, a sealing gasket 10, and a shock-absorbing groove 11.

[0025] A high-stability high-voltage connector for 10kV high-voltage transmission lines includes a socket, pins 5, and a plug. The socket and plug are connected by a flange 2. The socket has three inner insulating tubes 3 inside. The three inner insulating tubes 3 pass through a sealing gasket 10 and an inner limiting fixing plate 9 installed inside the socket in sequence. One end of the inner insulating tube 3 is inserted into the inner insertion end of the pin 5. A retaining ring 4 is fitted at the insertion point of the inner insulating tube 3 and the pin 5. The outer insertion end of the pin 5 is inserted into three outer insulating tubes 8 inside the plug. The inner wall of each pin 5 and the outer insulating tube 8 insertion point is provided with a power spring 6. The three outer insulating tubes 8 extend to the outside of the outer limiting fixing plate. The outer walls of the outer limiting fixing plate and the inner limiting fixing plate 9 are equipped with telescopic cable ties 7 for tightening the outer insulating tubes 8 and the inner insulating tubes 3.

[0026] Both the socket and the plug are encased in a housing 1, which protects the socket and plug from seawater salt spray corrosion, extends the service life of the socket and plug, and reduces the impact of the harsh marine environment on the connector.

[0027] The outer casing 1 is made of stainless steel, which has high corrosion resistance and can be used in harsh environments. It also has fire resistance, low temperature resistance and heat resistance, can resist scaling and maintain strength at high temperatures.

[0028] The sealing gasket 10, the inner limiting fixing plate 9, and the outer limiting fixing plate are all made of insulating materials. Most of these insulating materials are resistant to chemical corrosion, have excellent insulation and electrical resistance, are lightweight, easy to use, easy to process and manufacture, and are inexpensive.

[0029] The sealing gasket 10 has a shock-absorbing groove 11 on its side wall. The groove 11 is equipped with a hexagonal bolt that connects to the flange 2. The sealing gasket 10 and the shock-absorbing groove 11 work together to limit and dampen vibration. It has good heat treatment performance, high elastic limit, impact toughness, and fatigue limit, which improves the durability and stability of the internal components of the connector, prevents vibration and impact, reduces vibration frequency, and extends service life.

[0030] In use, a multi-stage shock absorption structure is employed. First, the shock-absorbing groove on the sealing gasket, in conjunction with hexagonal bolts, provides initial shock absorption to improve stability. Then, the inner and outer limiting fixing plates are used for fixation, achieving secondary shock absorption and improving stability. Next, the inner and outer limiting fixing plates are tightened using telescopic cable ties, achieving tertiary shock absorption and improving stability. Furthermore, each pin's inner wall at its connection with the outer insulating tube is equipped with a dynamic spring, capable of withstanding significant vibrations, providing a fourth level of shock absorption and improving stability. Finally, a retaining ring provides a fifth level of limiting and shock absorption, further enhancing stability.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
