Detailed Description
The utility model will be described in further detail below with reference to the drawings and specific examples.
As shown in fig. 1 to 4, the embodiment discloses a device for installing a tulip contact of a circuit breaker, which comprises a base 1 and a mounting plate 2, wherein the mounting plate 2 is sleeved on the top of the base 1, the mounting plate 2 is an annular plate, and the annular plate is formed by splicing at least two bodies.
When assembling the plum blossom contact of circuit breaker, the part that needs the assembly includes that the plum blossom touches finger 3, leaf spring 4, shield cover 5 and touches seat 6, and concrete installation step is:
step S1: fixing a base 1 on a workbench;
step S2: sleeving the mounting plate 2 on the top of the base 1;
step S3: sleeving the shielding cover 5 on the base 1;
step S4: pressing a plate spring 4 into the plum blossom-shaped contact finger 3, and inserting the plum blossom-shaped contact finger between the mounting plate 2 and the shielding case 5 along the inner wall of the shielding case 5;
step S5: after all the plum blossom contact fingers 3 are assembled, the contact seat 6 is arranged in the plum blossom contact fingers 3;
step S6: mounting the shielding cover 5 on the contact seat 6 by using screws;
step S7: the base 1 is taken out, and the plurality of bodies of the mounting plate 2 which are mutually supported are staggered and taken out respectively.
The device for installing the plum blossom contact of the circuit breaker is characterized in that the mounting plate 2 is designed to be formed by splicing at least two bodies, the base 1 is taken out firstly after the installation of the plum blossom contact finger 3 is completed, and the mounting plate 2 is formed by splicing a plurality of bodies and can be taken out in a staggered mode, so that the problem that the mounting plate 2 is difficult to pull out or cannot be pulled out due to too large clamping force of the plum blossom contact finger 3 is successfully solved.
In this embodiment, the mounting plate 2 is formed by cutting two half ring bodies, and the two half ring bodies are formed by cutting a whole ring, in other embodiments, the mounting plate 2 may also be formed by more than two bodies, for example, by dividing into three or four bodies.
In this embodiment, the outer edge of the mounting plate 2 is provided with a boss structure 21, the inner diameter of the boss structure 21 is slightly larger than the outer diameter of the top of the base 1, and when the mounting plate 2 is sleeved on the top of the base 1, the boss structure 21 is just in clearance fit with the outer peripheral wall of the base 1.
