Description

Technical Field

[0001] The utility model relates to the technical field of contactor brackets, and particularly relates to a high-speed switch contactor bracket. Background Technique

[0002] A contactor is an electrical component that uses electromagnetic, pneumatic or hydraulic principles to control the on-off of the main circuit through a control circuit. The contactor can control the switching on and off of a circuit within a certain current and voltage range. In practical applications, the contactor is often used to manually and automatically control the start and stop of electrical equipment such as motors and lights. The contactor bracket is an important internal component used to install the armature for operation. The current contactor bracket does not have a buffer and shock-absorbing structure, resulting in high noise and short service life. It also does not have a structure that facilitates the positioning and installation of the armature, and does not have a locking structure, resulting in the armature being prone to loosening. In view of this, in-depth research has been carried out on the above problems, and thus this case has emerged. Content of the Utility Model

Through the mutual extrusion of multiple first elastic rubber blocks 9 and second elastic rubber blocks 10 in the buffer pad 4, and the first elastic rubber blocks 9 and the second elastic rubber blocks 10 are deformed by extrusion, the buffering effect on the impact force is realized, thereby realizing the buffering and shock absorption effect of the armature 6.

[0028] One end of each knob 2 is connected with a first bevel gear 11, and a second bevel gear 12 is installed on the outer wall below the threaded rod 13, and a meshing transmission structure is formed between the second bevel gear 12 and the first bevel gear 11;

[0029] Internal threads are provided on the inner wall of the locking sleeve 16, external threads are provided on the outer wall of the welding pipe 22, and a threaded connection structure is formed between the locking sleeve 16 and the welding pipe 22;

[0032] Specifically, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , when using this structure, insert the positioning block 7 at the bottom end of the armature 6 into one end of the positioning groove 8, then push the armature 6 into the contact support body 3 from one end for positioning, then rotate the knob 2 to make the first bevel gear 11 rotate. Through the meshing of the first bevel gear 11 and the second bevel gear 12, the threaded rod 13 rotates simultaneously, and then through the threaded cooperation between the threaded rod 13 and the locking rod 14, the locking rod 14 moves upward into the locking groove 15, facilitating the positioning and installation of the armature 6.

[0033] Working principle: When using this device, first install the armature 6 into the contact support body 3 for use;

[0034] Implementation steps of the first innovation point:

[0035] The first step: Insert the positioning block 7 at the bottom end of the armature 6 into one end of the positioning groove 8, then push the armature 6 into the contact support body 3 from one end for positioning.

Then, through the threaded cooperation between the threaded rod 13 and the locking rod 14, the locking rod 14 moves upward into the locking groove 15 to achieve the positioning and installation of the armature 6.

[0036] The second step: Then rotate the locking sleeve 16 for threaded cooperation to make the locking sleeve 16 move toward one side of the connecting plate 20, and press the connecting plate 20 inside the locking sleeve 16. At the same time, the connecting rod 18 drives the clamping block 21 to engage into the clamping groove 17 to lock the knob 2.

[0037] Implementation steps of the second innovation point:
