Abstract

The utility model relates to a motor protector device, in particular to a motor protector with simple structure and reduced cost. The motor protector comprises a casing, a transformer and an electronic module board; and is characterized in that the casing is divided into a casing (1) and a casing (2), which are the same part; and during installation, the rear side of the casing (1) is buckled with the rear side of the casing (2); an operation panel (3) and the electronic module board (4) are installed on the casing, the operation panel (3) is movably connected with an operating panel clamping groove (102) on the casing, and the electronic module board (4) is movably connected with an electronic module board clamping groove (103) on the casing. The casing (1) and the casing (2) are buckled with each other to form a cabinet, so as to save a mold. The motor protector is composed of the transformer and the electronic module board, therefore, the motor protector has the advantages of simple structure, reduced cost, and ingenious overall structure.

Description

Motor protector

Technical field

The utility model relates to motor protection equipment, and is particularly simple in structure, the motor protector that cost reduces.

Background technology

Motor protector in the past now just only compares the current protector type, because current protector sensitivity is higher; therefore be widely used in electric power and the electrical apparatus industry, but, be mostly to adopt components and parts such as triode, diode with regard to conventional device; the circuit complexity; device is various, and volume is big, the cost height; especially the making of housing; complex process needs many screws during installation, load and unload all pretty troublesome.

The utility model content

The purpose of this utility model is at above-mentioned defective, and a kind of motor protector is provided.

The technical solution of the utility model is a motor protector, comprise housing, instrument transformer and electric sub-member plate, it is characterized in that said housing dimidiation, i.e. housing (1) and housing (2) and be same parts, the reverse side buckle connection mutually of the reverse side of housing during installation (1) and housing (2); Guidance panel (3) and electric sub-member plate (4) are installed on the housing, and the guidance panel draw-in groove (102) on guidance panel (3) and the housing flexibly connects, and the electronic building brick draw-in groove (103) on electric sub-member plate (4) and the housing flexibly connects.

Said housing (1) is provided with button window (105) and clasp (104) with housing (2), is separately positioned on the both sides and the bottom of housing; Housing (1) and the bottom of housing (2) are equipped with fixing metal pin (107) and plug with fixing feet hole (20 4) and be connected; Be provided with instrument transformer installing rack (101) in housing (1) and the housing (2), binding post plug (202) is by intelligent open closure (201) and terminal block (405) socket connection.

The utility model has the advantages that since housing be adopt positive and negative two buckles to be formed by connecting to be one box-like; therefore can save one pair of mould, and adopt instrument transformer and electric sub-member plate to form motor protector, therefore simple in structure; cost reduces, and integral body is exquisite more.

Description of drawings

Fig. 1 is the utility model stereogram.

Fig. 2 is the structural upright exploded view.

Embodiment

Further specify embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1, be stereogram, integral body is connected to form by the two halves buckle, just can continuously produce housing as long as make a mould like this, and positive and negative then interlocking forms, and three tube-shaped column bodies are to support three instrument transformers.Footing adopts dongle configuration.Housing is to adopt plastic injection-moulded making, and therefore saves one pair of mould.

Referring to Fig. 2, be the structural upright exploded view.Among the figure, 1-housing 1,2-housing 2,3-guidance panel, 4-electric sub-member plate, 5-current transformer; 101-instrument transformer frame, 102-guidance panel draw-in groove are arranged in the housing 1,103-electric sub-member plate draw-in groove, 104-housing button, 105-housing button window, the 106-screw hole, 107-installs and fixes metal leg, the 108-trip bolt; 201-intelligence open closure is arranged, 202-binding post plug, 203-through wires hole, 204-fixing feet hole, 205-trip bolt in the housing 2; The 3-guidance panel, 301-setting current knob, 302-knob hole, 303-potentiometer handle; The 4-electric sub-member plate, the 401-terminal block; The 5-current transformer.As shown, housing 1 is to be made with plastic injection-moulded, it is that the instrument transformer frame is made of three cylinders with the middle part that clasp 104 is separately positioned on the left and right sides and bottom shell 1 that housing 1 is provided with button window 105, current transformer is installed on these three cylinders, innovative point of the present utility model is that housing is made two halves, be housing 1 and housing 2, and both are the same, just with the reverse side mutually buckle connection of housing 1 with housing 2.Guidance panel 3 is installed on the housing with electric sub-member plate 4, and guidance panel 3 is plugged in the draw-in groove 102 on the housing and flexibly connects; Electric sub-member plate 4 also is plugged in the draw-in groove 103 in the housing and flexibly connects.Terminal block 405 is installed on the electric sub-member plate 4, and binding post plug 202 is by intelligent open closure 201 and terminal block 405 socket connections.The fixing feet hole 205 that installs and fixes metal leg 107 and bottom also is to adopt socket connection.

Claims

1, motor protector comprises housing, instrument transformer and electric sub-member plate, it is characterized in that said housing dimidiation, i.e. housing (1) and housing (2) and be same parts, the reverse side buckle connection mutually of the reverse side of housing during installation (1) and housing (2); Guidance panel (3) and electric sub-member plate (4) are installed on the housing, and the guidance panel draw-in groove (102) on guidance panel (3) and the housing flexibly connects, and the electronic building brick draw-in groove (103) on electric sub-member plate (4) and the housing flexibly connects.
