Embodiment Construction

[0030] See Figure 1-11 As shown, the terminal block of the low-voltage fixed circuit breaker of the present invention includes a plurality of independent connection terminals 3, a cover plate 4, positioning pieces 2 at both ends, and a plurality of connection terminals 3 and cover plates for connecting two positioning pieces 2. 4, the two positioning members 2 of the present invention are arranged symmetrically.

[0031] See figure 1 As shown, the connecting terminals 3 of the present invention are arranged side by side in turn. Since the connecting terminals 3 have the same structure, the connecting terminals 3 can be used in series, so the number of connecting terminals 3 can be increased or decreased according to the current level, and the wiring of the circuit breaker can be changed. The width of the seat is suitable for fixed circuit breakers of different current levels.

[0032] See Figure 1-8 As shown, each connecting terminal 3 of the present invention is arranged...

Abstract

The invention relates to a wire holder for a low-voltage fixed-type circuit breaker, and the wire holder comprises a plurality of independent wiring terminals, a cover plate, and positioning parts at two ends. A guide rail passes through the positioning parts, the guide rail installation holes on all substrates and the cover plate to be connected with the positioning part. Moreover, each wiring terminal comprises a substrate, a long contact piece, a short contact piece, a wire pressing plate, a bolt, and a nut. Each substrate comprises a partitioning plate and a seat body, which are integrated together. The vertical side of each seat body is provided with short and long contact piece grooves from the front to the back, and each seat body is provided with a guide installation hole for allowing the guide rail to pass. The long contact pieces are disposed in the long contact piece grooves of the seat bodies, and the bolts pass through the via holes of the wire pressing plates and the long contact pieces to be connected with the screws in external limiting grooves. The short contact pieces are disposed in the short contact piece grooves of the seat bodies, and the bolts pass through the via holes of the wire pressing plates and the short contact pieces to be connected with the nuts in internal limiting grooves. The wire holder is simple in structure, is convenient to install, can achieve miniaturization, is suitable for different current levels, and can meet the vertical wiring demands of a user.

Description

technical field [0001] The invention relates to a terminal block of a low-voltage fixed circuit breaker, belonging to the technical field of low-voltage fixed circuit breakers. Background technique [0002] When dangerous faults such as short circuit, severe overload, and voltage loss occur in the circuit, the low-voltage circuit breaker can automatically cut off the faulty circuit, effectively protecting the electrical equipment connected in series behind it. Therefore, the low-voltage circuit breaker is a very important protective device in the low-voltage distribution network. Compared with the drawer type circuit breaker, the fixed circuit breaker of the same model and the same current level has the advantages of consistent technical performance indicators, small size and low price. Therefore, fixed circuit breakers are widely used. [0003] The electrical part of the circuit breaker is divided into the main circuit and the control circuit, and the terminal block of th...
