Embodiment approach
[0050] The specific embodiment is as follows: using the linkage effect between the linkage tooth plate 508 and the linkage gear 509 to transfer the linear force to another embedded elastic washer 504, so that the two embedded elastic washers 504 are close to each other. , and because the embedded elastic gasket 504 will automatically change the shape of the force-bearing surface when it is subjected to resistance, the external wire 4 is tightly clamped and connected between the two, and the external wire 4 is not connected in series. The sealing mechanism 5 of the wire 4 can also achieve the sealing effect, and after the box cover 206 is opened, driven by the restoring elastic force of the first support spring 507, the sliding connection jacket 503 will be pushed through the sliding connection groove 506 on the sliding connection seat 505. The surface slides, so that the clamping effect of the embedded elastic gasket 504 on the external wire 4 can be released.

The invention discloses an electrical connection device, and belongs to the technical field of electrical equipment, the electrical connection device comprises an electrical cabinet body, the interior of the electrical cabinet body is fixedly connected with a wiring external mechanism, and the end face of the inner side of the wiring external mechanism is fixedly connected with a butt joint type connector lug. According to the invention, under the mutual cooperation of the designed structures such as the external wiring assembly, the sealing mechanism, the pressure relief assembly and the cooling mechanism, the electric corrosion resistance and heat dissipation performance are good, the overall practicability is high, the requirements of a user are met, meanwhile, the stability of an external wire after electrical connection is completed is also improved, the pressure in the junction box is relieved, and the service life of the junction box is prolonged. In the pressure relief process, high-temperature gas in the arc column can be driven, the effects of cooling and pressure relief are achieved, cooling of the arc can be accelerated through attraction generated by rotating airflow, the purpose of increasing the axial gradient of the voltage of the arc column is achieved, the temperature of the contact can be reduced due to cooling of the arc, and therefore the purpose of increasing the near-pole voltage drop can be achieved.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an electrical connection device. Background technique [0002] Electrical cabinets are mainly used in the chemical industry, power system, environmental protection industry, industry, metallurgical system, nuclear power industry, fire safety monitoring and transportation industries, etc. The electrical cabinet terminals are accessories used to realize electrical connection. "A new type of multifunctional maintenance device for electrical automation" (public number: CN111511139B), the technical problem solved by this patent is that the traditional maintenance protection device cannot protect the electrical automation equipment internally and externally, and the electrical automation equipment cannot be very Good protection effect The traditional maintenance requires the staff to spend a long time to operate manual inspection, which is time-consuming and in...
