Abstract
The utility model relates to the technical field of a circuit breaker, in particular to a small-sized low-voltage circuit breaker. The small-sized low-voltage circuit breaker comprises a shell body. Internal elements and components are arranged in the shell body, a lead wire switch-in end and a standard bus bar connection-inserting groove are arranged at the end face of the shell body, a wire connection board is arranged in the shell body corresponding to the positions of the lead wire switch-in end and the standard bus bar connection-inserting groove, a wire connection clamp is sleeved on a bottom board of the wire connection board, a guide hole is arranged at a top board at the upper end of the wire connection board, a threaded hole is arranged at the upper end of the wire connection clamp corresponding to the guide hole, a wire connection screw is connected with the wire connection clamp in a threaded manner after penetrating through the guide hole and the threaded hole, and the groove walls at the two sides of the standard bus bar connection-inserting groove are fixed on the shell body in a separated manner. When in use, both a lead wire and a bus bar can be connected, and the convenient wire connection method is provided.
Description
Technical field:
The utility model relates to the termination technical field, particularly a kind of termination of circuit breaker.
Background technology:
Termination is the vitals in the circuit breaker, and its function is with in the circuit breaker place in circuit.The termination of circuit breaker generally comprises terminal block and terminal screw, and terminal block is used for being communicated with lead, and terminal screw is used for lead overlayed with terminal block is in the same place, and avoids wire dropping.General termination being arranged as in Shell of circuit breaker: the side of housing is provided with the lead incoming end or the standard bus-bar patches groove, corresponding lead incoming end or standard bus-bar patch the groove position and are provided with terminal block in the housing, terminal block is used to connect electric wire or standard bus-bar, makes in the circuit breaker place in circuit.Yet existing small low-voltage circuit breaker is provided with the lead incoming end separately mostly or the standard bus-bar patches groove, and corresponding its mode of connection of termination is also fixing and single, makes troubles for the user when selecting the different modes of connection.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of termination of circuit breaker, and this termination can connect lead, can connect bus-bar again, has the mode of connection easily.
For achieving the above object, the utility model adopts following technical scheme:
A kind of termination of circuit breaker, comprise terminal block, binding clip and terminal screw, described terminal block top is bent into " U " shape, and the upper end of its " U " shape kink is the top board that is used to connect bus-bar, and the lower end is the base plate that is used to connect lead, described binding clip is socketed on the base plate, offer pilot hole on the described top board, the corresponding pilot hole in binding clip upper end offers screwed hole, and the screwed hole hole wall is provided with screw thread, described terminal screw passes pilot hole and screwed hole, is threaded with binding clip.
Wherein, groove all is carved with in described base plate lower surface, binding clip lower end inner face and top board upper surface.
The utility model beneficial effect is: from such scheme as can be seen, when needing to insert lead, lead is placed between base plate and the binding clip, turns terminal screw, upwards promote clamping wire thereby drive binding clip, make lead be close to base plate; When needing to insert bus-bar, the standard bus-bar is stuck between top board and the terminal screw, tightens terminal screw, make bus-bar be close to described top board; Can connect lead, can connect bus-bar again, the mode of connection easily is provided.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is structural representations of the utility model terminal block;
Accompanying drawing 3 is the utility model binding clip structural representations;
Accompanying drawing 4 is the utility model assembling schematic diagrames in circuit breaker.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in the accompanying drawing 1～3, a kind of termination of circuit breaker, comprise terminal block 1, binding clip 2 and terminal screw 3, described terminal block 1 top is bent into " U " shape, the upper end of its " U " shape kink is the top board 12 that is used to connect bus-bar, the lower end is the base plate 11 that is used to connect lead, described binding clip 2 is socketed on the base plate 11, offer pilot hole 13 on the described top board 12, the corresponding pilot hole 13 in binding clip 2 upper ends offers screwed hole 21, and screwed hole 21 hole walls are provided with screw thread, and described terminal screw 3 passes pilot hole 13 and screwed hole 21 is threaded with binding clip 2.
See accompanying drawing 1 and accompanying drawing 4, when the utility model uses, if insert lead in circuit breaker 4, lead is placed between base plate 11 and the binding clip 2, turns terminal screw 3, drive binding clip 2 and upwards promote, thereby lead is clamped by base plate 11 and binding clip 2, make lead be close to base plate 11; When needing to insert bus-bar, the standard bus-bar is stuck between top board 12 and the terminal screw 3, tightens terminal screw 3, make bus-bar be close to described top board 12; Can connect lead, can connect bus-bar again, the mode of connection easily is provided.
Wherein, groove 5 all is carved with in described base plate 11 lower surfaces, binding clip 2 lower end inner faces and top board 12 upper surfaces, and these grooves 5 can make the frictional force on surface become big, and lead or bus-bar insert the back difficult drop-off.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
