Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an ultra-high voltage connector socket. Background Technology

[0002] The primary function of connectors is to enable circuit connection and signal transmission. There are many types of connectors, such as plugs, pin headers, sockets, and wire harnesses. Standard connectors are suitable for low- or medium-voltage applications, ranging from a few volts to several hundred volts, and are commonly used in household appliances, consumer electronics, and automotive low-voltage systems. Standard connectors have lower voltage requirements and are simpler to design. Ultra-high voltage connectors are suitable for high-voltage environments ranging from several thousand volts to tens of thousands of volts, and are commonly used in power transmission, medical equipment, and industrial equipment. Ultra-high voltage connectors must withstand extreme voltages without breakdown or arcing.

[0003] Currently, with the trends of polymerization, digitalization, lightweighting, and environmental protection in ultra-high voltage connectors, in certain extreme environments, including high temperature, high pressure, strong vibration, and strong electromagnetic interference, it is necessary to meet the ultra-high voltage requirements of the connector while ensuring the reliability of the entire system under high vibration loads. Connectors cannot simultaneously meet these conditions. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems by designing an ultra-high voltage connector socket that can meet the high voltage withstand requirements of over 10,000 volts and the current carrying capacity of over 1,000 amperes, while also possessing good vibration and shock resistance. The technical solution adopted is as follows:

[0005] An ultra-high voltage connector socket includes an ultra-high voltage socket comprising an epoxy shell. Inside the epoxy shell, a flange insert, a grounding bolt, a shielding cap, a shielding mesh, and a contact are sequentially embedded. The grounding bolt, shielding cap, and shielding mesh are distributed around the outer ring of the flange insert and the contact. The grounding bolt is threadedly connected to the shielding cap, and the shielding mesh is press-fitted to the outer ring of the shielding cap. The flange insert has circumferentially distributed windows and a first internal thread. The grounding bolt has an external thread and a second internal thread. The ultra-high voltage socket and the corresponding ultra-high voltage plug are connected via the first internal thread on the flange insert. The shielding cap has an outer ring step and circumferentially distributed threaded holes. The external thread connects to the threaded holes, and both ends of the shielding mesh connect to the outer ring step.

[0006] As mentioned above, the shielding mesh has evenly distributed circular holes on a cylindrical surface, which allow the entire shielding mesh to be bonded within the epoxy shell.

[0007] As described above, the grounding bolt and the shielding cap are connected via corresponding external threads and evenly distributed threaded holes around the perimeter; the circular holes at both ends of the shielding mesh are interference-fitted with the outer stepped outer ring of the shielding cap.

[0008] The contact element described above has a deep cavity and a circular flared opening, and the deep cavity makes contact with the contact element of the mating plug.

[0009] As described above, the epoxy shell has an inner conical surface, and the epoxy shell and the inner conical surface are integrally formed.

[0010] Compared with the closest existing technology, the technical solution provided by this utility model has the following beneficial effects:

[0011] 1. This ultra-high voltage connector socket uses shielding bolts and shielding mesh at the front and rear ends of the shielding cover. The outer shell shielding structure is connected through threads and corresponding riveting methods. At the same time, the shielding bolts at both ends are used to achieve effective grounding to ensure that the metal parts at this point are at the same potential as the epoxy shell.

[0012] 2. This ultra-high voltage connector socket features an inner conical surface of an integrally molded epoxy shell to ensure reliable connection with the corresponding plug seal. Simultaneously, a deep cavity in the socket allows for complete insertion of the corresponding plug contact. A flared end of the socket completely encloses the compression interface, acting as an equalizing ring. This ensures equipotential between the plug contact and the flared end, preventing high-voltage breakdown of the epoxy shell in this section.

[0013] 3. The grounding bolt, shielding cap, and shielding mesh of this ultra-high voltage connector socket are sequentially distributed on the outer ring of the flange insert and the contact, which can ensure that this position is at zero potential with the epoxy shell and the flange insert. For the voltage level of this ultra-high voltage socket, the pressure resistance performance of the epoxy shell is the key consideration. By setting different thicknesses of epoxy shells with higher dielectric strength, ultra-high pressure resistance performance can be achieved. Depending on the size of the rubber parts, it can meet the pressure resistance level of hundreds of kilovolts and above. Furthermore, the threaded connection also has good vibration and shock resistance, meeting the vibration performance requirements of more than 20g. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7 This utility model provides a technical solution:

[0024] An ultra-high voltage connector socket includes a flange insert 1, a grounding bolt 2, a shielding cap 3, a shielding mesh 4, a contact 5, and an epoxy shell 6. The external thread 21 of the grounding bolt 2 is connected to the evenly distributed threaded holes 32 around the perimeter of the shielding cap 3. The two ends of the shielding mesh 4 are connected to the outer ring steps 31 of the shielding cap 3 to form a complete internal shielding function. At the same time, the second internal thread 22 on the grounding bolt 2 can achieve reliable external grounding.

[0025] The shielding mesh 4 has evenly distributed circular holes 41 on its cylindrical surface, ensuring effective adhesion of the entire shielding mesh 4 within the epoxy shell 6. The grounding bolt 2 and the shielding cap 3 are effectively connected via corresponding external threads 21 and evenly distributed threaded holes 32 around the perimeter. The circular holes 41 at both ends of the shielding mesh 4 are interference-fitted with the outer ring steps 31 on the shielding cap 3.

[0026] Grounding bolt 2, shielding cap 3, and shielding mesh 4 are sequentially distributed around the outer ring of flange insert 1 and contact 5. Flange insert 1, grounding bolt 2, shielding cap 3, shielding mesh 4, and contact 5 are sequentially embedded inside epoxy shell 6. The integrally formed inner conical surface 61 on epoxy shell 6 allows for reliable connection with the corresponding plug seal. The deep cavity 51 on contact 5 allows for complete insertion of the corresponding plug contact, ensuring effective contact with the mating plug contact. The circular flared opening 52 completely encloses the compression interface, acting as an equalizing ring. This structure ensures equipotential between the plug contact and the circular flared opening 52, preventing high-voltage breakdown of the epoxy shell in this section. For the voltage withstand rating of this ultra-high voltage socket, the voltage withstand performance of the epoxy shell material itself is considered. By setting different insulation thicknesses for epoxy shells with higher dielectric strength, ultra-high voltage withstand performance can be achieved. Furthermore, the threaded connection provides good vibration and impact resistance.

[0027] The working principle of this ultra-high voltage connector socket is as follows: The corresponding ultra-high voltage connector plug is inserted into the ultra-high voltage connector socket according to the usage requirements. The pin contact on the plug is fully inserted into the deep cavity of the ultra-high voltage connector socket contact, ensuring reliable contact and power transmission between the plug and the socket. The sealing rubber part on the ultra-high voltage connector plug is pressed tightly against the inner conical surface of the ultra-high voltage connector socket, ensuring reliable contact of the entire mating sealing interface and eliminating air gaps to ensure its ultra-high pressure resistance. The plug and socket are reliably connected through the threads provided on them, achieving a sealing effect while taking into account vibration resistance.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art can still make modifications or equivalent substitutions to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the claims of this utility model pending approval.
