Abstract
The utility model relates to a novel circuit glass sealing wiring terminal, which comprises a shell (1), wherein a glass insulator (3) is connected in the shell, and the glass insulator (3) is internally connected with a group of leads (2). The novel circuit glass sealing wiring terminal is characterized in that an annular groove (4) is arranged in a connecting hole of the shell, and an annular heave (3a) connected and matched with the annular groove is arranged on the glass insulator. The novel circuit glass sealing wiring terminal has the advantages that the annular heave is connected and matched with the annular groove, the sealing area of the glass insulator is increased, thus the sealing strength is improved, and the problem of air leakage is well solved. The novel circuit glass sealing wiring terminal can be suitable for being used in serious conditions, and overcomes the defect of SF6 air leakage in traditional circuit glass sealing wiring terminals.
Description
Technical field
The utility model relates to the binding post in a kind of electric elements, particularly a kind of novel circular glass sealed wiring terminal.
Background technology
Circular glass sealed wiring terminal is to be used for using the combined electrical apparatus of SF6 gas for insulation and arc-extinguishing medium, as: electrical equipment such as circuit breaker, on-pole switch, transformer, instrument transformer, the flexible device of density monitor.It is the critical component of combined electrical apparatus, and it mainly acts on and prevents under high pressure (general pressure is 5 ~ 6 atmospheric pressure) SF6 gas leakage, thereby improves the insulation and the arc extinguishing intensity of electrical equipment.Can in rugged environment, use.Circular glass sealed wiring terminal has various ways such as four-core, six cores, is made up of lead-in wire, housing, electronic glass.In the structure of existing circular glass sealed wiring terminal, shell is to adopt the mode of melting and the shell of electrical equipment to weld together, and inside is full of SF6 gas; Create the environment of a high insulation; Under harsh conditions, during electrical equipment uses throughout the year, be easy to generate the defective of SF6 gas gas leakage; The high temperature that produces during simultaneously owing to soldering and sealing makes glass insulator crack easily and leaks gas, make the reliability decrease of electrical equipment.
The utility model content
The purpose of the utility model is exactly the problem that exists in the prior art in order to solve, a kind of novel circular glass sealed wiring terminal that provides.
The technical scheme that the utility model adopts is:
A kind of novel circular glass sealed wiring terminal; Comprise shell, be connected with glass insulator in the shell, connect one group of lead-in wire in the glass insulator; It is characterized in that: be provided with cannelure in the connecting hole of shell, glass insulator is provided with annular protrusion and is connected cooperation with cannelure.
The advantage of the utility model is:
Said annular protrusion is connected cooperation with cannelure, it has increased the sealing-in area of glass insulator, thereby has improved sealing strength, has well solved the gas leakage problem of product.Can be applicable under harsh conditions, overcome the defective of the SF6 gas gas leakage in the existing product.
Description of drawings:
Fig. 1 is the cutaway view of the utility model.
Embodiment:
As shown in Figure 1, a kind of novel circular glass sealed wiring terminal comprises shell 1, is connected with glass insulator 3 in the shell, connects one group of lead-in wire 2 in the glass insulator.Be provided with cannelure 4 in the connecting hole of shell, glass insulator 3 is provided with annular protrusion 3a and is connected cooperation with cannelure 4.Fill up cannelure when glass insulator and the fusing of shell sintering, the cooling back forms said annular protrusion, and it has increased the sealing-in area of glass insulator, thereby has improved sealing strength, has well solved the gas leakage problem of product.
