Detailed Description
The main principle of the invention is as follows:
the non-linear motion contact is electrically connected with the bus, and the movable contact is ensured to be reliably electrically connected in the whole motion process through a movable joint type connection mode and the pressing force of the spring pin.
As shown in fig. 1 and 2, the deformable conductive connection mechanism 100 includes a contact guide seat 110 for mounting each conductive connection component, the contact pieces 120 and 130 are provided with limit pin mounting holes 120a and 130a and spring pin mounting holes 120b and 130b, the limit pin 140 passes through the limit pin mounting holes 120a and 130a, and the spring pin 150 passes through the spring pin mounting holes 120b and 130 b; the contact pieces 120, 130 are mounted at both sides 111, 112 of the contact guide 110 by a stopper pin 140 and a spring pin 150.
The vacuum switch moving contact 150 is in contact with the contact pieces 120 and 130 under the guiding action of the contact guide 110, so that the contact pieces 120 and 130 can reliably keep in contact with the vacuum switch moving contact 150 in the whole movement process of the vacuum switch moving contact 150.
The contact pieces 120 and 130 move in the limit range of the limit pin 140, and the spring pin 150 is used for adjusting the pressing force of the contact pieces 120 and 130 on the vacuum switch moving contact 150;
the spring pin 150 comprises a pin 151, a spring 152 and a pressing sleeve 153 which are matched, and the pressing force of the adjusting contact pieces 120 and 130 on the vacuum switch movable contact 150 is adjusted by adjusting the pressure of the spring 152 of the spring pin 150.
The contact pads 120, 130 are connected to the contact base 190 via contact balls 160, 170.
Two spherical contact pits 191 and 192 are formed in two sides of the inner side of the contact seat 190, the contact balls 160 and 170 are respectively placed in the spherical contact pits 191 and 192, and the contact balls 160 and 170 and the spherical contact pits 191 and 192 form movable joints.
The contact seat 190 is fixed on the contact guide seat 110, and the contact balls 160 and 170 in the contact blades 120 and 130 are placed in the spherical contact pits 191 and 192, so that the contact blades 120 and 130 are reliably contacted with the contact seat 190 through the contact balls 160 and 170 when being deformed and moved. The bus bar 180 is connected to the contact base 190.
The working principle of the invention is as follows:
the vacuum switch movable contact 150 is guided by the contact guide 110 into the contact pads 120, 130 to the switch-on position.
When the vacuum switch movable contact 150 just enters the contact pieces 120 and 130, the contact pieces 120 and 130 move towards both sides, so that the vacuum switch movable contact 150 can more easily enter the position between the contact pieces 120 and 130.
And the movable joint type connection of the contact balls 160 and 170 and the contact seat 190 and the existence of the spring pin 150 and the limit pin 140 can ensure that the movable contact 150 of the movable vacuum switch is always in reliable contact with the contact pieces 120 and 130 in the motion process.
The pressing force between the vacuum switch moving contact 150 and the contact pieces 120 and 130 is adjusted by adjusting the pressing force of the spring 152 in the spring pin 150, and the design of the spring pin 150 can simultaneously ensure that the vacuum switch moving contact 150 keeps pressure constantly in the moving process between the contact pieces 120 and 130 so as to ensure the reliability of the switch and ensure the contact pieces 120 and 130 and the bus 190.
In summary, the deformable conductive connection mechanism 100 of the present invention can achieve the conductive connection between the movable contact 150 of the vacuum switch and the bus 180, which do not move linearly, and can ensure the reliable connection of the movable contact 150 of the vacuum switch in the whole moving process by the movable joint type connection of the contact balls 160 and 170 and the existence of the pressing force of the spring pin 150.
Because the traditional contact conductive connection mode has a plurality of limitations, the invention well makes up the defect that the contact connection cannot be applied, and ensures the reliability of the whole set of switch equipment.
