Abstract

The invention discloses a totally-enclosed installation structure of an outdoor circuit breaker cable. The totally-enclosed installation structure comprises a wiring terminal on a circuit breaker, a wiring card on a cable head and an enclosed hood. A binding post is arranged on the wiring end, a sleeving end corresponding to the binding post is arranged on the cable head wiring card, and the enclosed hood comprises a first barrel body and a second barrel body which are connected to the wiring end and the cable head in a sleeving manner, and barrel-shaped sealing parts which are respectively arranged behind the barrel bodies. According to the invention, the structure is reasonable, the cable head is connected with the binding post of the circuit breaker through the wiring card, then the cable head is insulated and isolated from the outside via the enclosed hood, and the sealing part is used for realizing sealing, so that the waterproof, moistureproof, corrosion-reducing and aging-reducing effects on the connecting part are realized, and the technical problems of inconvenience in use and poor sealing effect in the prior art are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an outdoor circuit breaker cable fully enclosed installation structure. Background technique [0002] The outdoor circuit breaker is provided with a terminal, and the terminal is connected with the cable lug. There are mainly two types of terminals for circuit breakers, one is a terminal, and the other is an end row with a hole at the terminal; a terminal card with a connection hole is provided on the cable terminal. When connecting, the connection hole of the cable connection card is socketed on the terminal post, or socketed with the hole of the terminal row, and fixed by bolts. After fixing, it is socketed by the insulating sheath to realize sealing. [0003] Connect the terminal post with the terminal card, and then fix it with bolts. The diameter of the connection hole of the terminal card is larger than that of the terminal post. After the socket i...
