Description

Technical Field

[0001] This utility model belongs to the field of electrical connection equipment, and particularly relates to a static contact seat. Background Technology

[0002] In current high-voltage power systems, stationary contact bases are crucial components for establishing electrical connections between electrical equipment, and their performance and safety are paramount. Traditional stationary contact bases primarily focus on power transmission, with relatively simple structures, typically only possessing basic conductive connections. When grounding is required for equipment maintenance or repair, existing stationary contact bases often lack integrated grounding functionality. This necessitates operators to separately install grounding lines and devices, a cumbersome process that is not only time-consuming and labor-intensive but also prone to safety hazards due to improper operation. Furthermore, additional grounding devices present challenges in terms of connection stability and reliability. For example, loosening or corrosion at the connection point can increase grounding resistance, failing to effectively conduct charges from the equipment to the ground, thus threatening the personal safety of operators.

[0003] With the continuous development of power systems and the increasing diversification of application scenarios, different electrical equipment has different requirements for grounding and connection methods. However, existing static contact bases, due to their single function, cannot flexibly adapt to various complex usage environments and special requirements. Utility Model Content

[0005] To solve the above problems, the technical solution adopted by this utility model includes: an insulating sleeve and a conductive component disposed within the insulating sleeve. The conductive component comprises a conductive rod, a stationary contact, a nut assembly, and a grounding contact blade. The conductive rod is disposed at the rear end of the insulating sleeve, with its tail extending out of the insulating sleeve and connected to the nut assembly. The stationary contact is disposed within a contact mounting cavity at the front end of the insulating sleeve, and its rear end is connected to the conductive rod. The grounding contact blade is integrally formed within the insulating sleeve and includes an integrally formed connecting hole, a connecting strip, and a blade-shaped grounding contact. The connecting hole is sleeved behind the terminal head at the front end of the conductive rod. The connecting strip is laterally connected to the connecting hole and the blade-shaped grounding contact. The blade-shaped grounding contact is vertically fixed within a wiring groove at the lower end of the insulating sleeve.

[0006] By twisting the connecting bar, the knife-shaped grounding contact is vertically positioned within the wiring groove of the insulating sleeve.

[0007] The stationary contact is movably disposed within the contact mounting cavity of the insulating sleeve, and its rear end is connected to the conductive rod via a flexible wire.

[0008] The blade-shaped grounding contact has a through hole at its rear end.

[0009] An insulating plug is fixed to the front end of the contact mounting cavity of the insulating sleeve, and the center of the insulating plug is provided with a flared guide hole that smoothly transitions with the insertion hole of the stationary contact.

[0010] The nut assembly includes an insulating washer, a copper washer, a wire clamp, a copper pressure plate, a flat washer, a spring washer, and a nut, which are sequentially arranged at the rear end of the conductive rod.

[0011] Both the surface of the insulating sleeve and the sidewall of the wiring groove are provided with a set of anti-creep ribs.

[0019] Reference Figure 1-3As shown, the present invention discloses a stationary contact holder with a grounding blade, comprising an insulating sleeve 1 and a conductive assembly 2 disposed within the insulating sleeve 1. The conductive assembly 2 includes a conductive rod 3, a stationary contact 4, a nut assembly 5, and a grounding blade 6. The conductive rod 3 is disposed at the rear end of the insulating sleeve 1, with its tail extending out of the insulating sleeve 1 and connecting to the nut assembly 5. The stationary contact 4 is disposed within a contact mounting cavity 7 at the front end of the insulating sleeve 1, and its rear end is connected to the conductive rod 3. The stationary contact 4 is also commonly referred to as a female terminal or a socket terminal. The grounding blade 6 is integrally formed within the insulating sleeve 1, and includes an integrally formed connecting hole 8, a connecting strip 9, and a blade-shaped grounding contact 10. The connecting hole 8 is sleeved behind the terminal block 11 at the front end of the conductive rod 3 and secured by the nut assembly 5, achieving a tight connection with the conductive rod 3. The connecting strip 9 is horizontally connected to the connecting hole 8 and the blade-shaped grounding contact 10. The blade-shaped grounding contact 10 is vertically fixed in the wiring groove 12 at the lower end of the insulating sleeve 1 to facilitate cooperation with the grounding switch. The wiring groove 12 has a U-shaped cross-section, which allows it to partially surround the blade-shaped grounding contact 10, thereby isolating the blade-shaped grounding contact 10 and improving safety.

[0020] Preferably, by twisting the connecting strip 9 to form a twisting portion 26, the blade-shaped grounding contact 10 can be vertically disposed within the wiring groove 12 of the insulating sleeve 1. The vertical orientation of the blade-shaped grounding contact 10 facilitates wiring, and by integrally forming the twisted connecting strip 9 within the insulating sleeve 1, its stability and strength are improved.

[0021] Preferably, the stationary contact 4 is movably disposed within the contact mounting cavity 7 of the insulating sleeve 1, and the rear end of the stationary contact 4 is connected to the conductive rod 3 via a flexible wire 13. This allows the stationary contact 4 to move freely, enabling it to self-align when the moving contact of the power distribution body is inserted into the stationary contact 4, thereby ensuring that no jamming occurs during insertion.

[0022] Preferably, the rear end of the knife-shaped grounding contact 10 is provided with a through hole 14. When the moving contact of the grounding switch quickly closes with the knife-shaped grounding contact 10, the pressure can be released through the through hole 14, reducing vibration. In addition, the through hole 14 can also be connected to a grounding wire for convenient wiring.

[0023] Preferably, an insulating plug 15 is fixed to the front end of the contact mounting cavity 7 of the insulating sleeve 1. The insulating plug 15 has a flared guide hole 16 at its center that smoothly transitions with the insertion hole of the stationary contact 4. This better guides the moving contact of the power distribution body to accurately insert into the stationary contact 4. In addition, it also serves as an electrical isolation device, effectively isolating current and preventing short circuits.

[0024] Preferably, the nut assembly 5 includes an insulating washer 17, a copper washer 18, a wire clamp 19, a copper pressure plate 20, a flat washer 21, a spring washer 22, and a nut 23, which are sequentially disposed at the rear end of the conductive rod 3. Using this nut assembly achieves more stable and safer wiring and prevents loosening.

[0025] Preferably, both the surface of the insulating sleeve 1 and the sidewall of the wiring groove 12 are provided with a set of anti-creep ribs 24. This serves to prevent creepage and simultaneously improve the strength of the insulating sleeve 1.

[0026] Preferably, a set of circumferentially arranged screw holes 25 are provided between the contact mounting cavity 7 and the side wall of the insulating plug 15. The insulating plug 15 is fixed by screwing screws into the screw holes 25 to improve the stability of the connection.

[0027] The foregoing is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
