Abstract
The utility model discloses a novel contact base of a vacuum interrupter with a shock absorption device. The novel contact base is characterized by comprising a contact base (1), two or more locating slots (2) disposed on bottom of bowl shape of the contact base, a circular type bounce slot (3) disposed under the locating slots (2), and locating pins (5) disposed outside reinforcing ribs (4). The number of the locating pins (5) is the same with the locating slots (2), and positions of the locating pins (5) are corresponding to the locating slots (2). The reinforcing ribs (4) are fixed on the contact base (1) through cooperation of the locating pins (5) and the bounce slot (3). The cooperation of the contact base and the reinforcing ribs (4) is non-fixed structure. The locating pins would bounce in the bounce slot when switching on, thereby reducing bounce between a moving contact and a fixed contact, prolonging service life of the vacuum interrupter, and improving usage effect of a product.
Description
Technical field
The utility model relates to a kind of novel contact base of vacuum interrupter with impact absorbing device, belongs to the vacuum interrupter technical field.
Background technology
In the existing vacuum interrupter, mostly be " worker " font or " horn mouth " type as the reinforcement of using in contact, the contact base bracing or strutting arrangement.When contact base becomes assembly with contact, reinforcement soldering, the three forms an integral body, and the deformation of generation is very little.In mechanism's making process, when closing a floodgate, moving contact and fixed contact form rigid collision, very easily produce spring.In vacuum circuit-breaker, if mechanical property produces spring (greater than 3ms), little gap arcing between two contact electrodes has increased the weight of the electric scaling loss of electrode, has a strong impact on the vacuum interrupter life-span, simultaneously electrical network is impacted, and produces overvoltage.
Summary of the invention
The purpose of this utility model is: a kind of novel contact base of vacuum interrupter with impact absorbing device is provided.The spring that contact produced when Novel strengthening rib can reduce the vacuum interrupter combined floodgate.
The utility model is to consist of like this: comprise adding contact base, contact base bowl type bottom has the location notch more than 2 or 2, the location notch below has the spring groove of circumference type, the reinforcement outside is provided with and alignment pin corresponding to location notch number same position, and reinforcement is fixed on contact base by alignment pin and spring groove.
Above-mentioned reinforcement below is connected with contact assembly.
Compared with prior art, the utility model contact base is the on-fixed structure with cooperating of reinforcement, and alignment pin can produce spring in the spring groove when closing a floodgate, thereby reduces the spring between moving contact and the fixed contact.
Description of drawings
Accompanying drawing 1 is the utility model contact base structural representation;
Accompanying drawing 2 is the utility model contact base vertical view;
Accompanying drawing 4 is the utility model reinforcement vertical view;
Accompanying drawing 5 is the utility model assembling schematic diagram.
Be labeled as in the accompanying drawing: 1-contact base, 2-location notch, the 3-groove that bounces, 4-reinforcement, 5-alignment pin, 6-contact assembly.
Embodiment
Comprise contact base 1 such as Fig. 1,1 bowl of type bottom of contact base has 4 location notchs 2, location notch 2 belows have the spring groove 3 of circumference type, alignment pin 5 corresponding to 4 positions of reinforcement 4 arranged outside, reinforcement 4 is fixed on contact base 1 by alignment pin 5 and spring groove 3, and reinforcement 4 belows and contact assembly 6 are connected by soldering.This kind structure contact base and 1 reinforcement 4 adopt active link, alignment pin 5 can produce spring in that spring groove 3 is interior, can play the spring effect that reduces between moving contact and the fixed contact during combined floodgate, it is long to solve closing time with this, so that vacuum interrupter is elongated useful life, improve the result of use of product.
Claims (2)
1. novel contact base of vacuum interrupter with impact absorbing device, it is characterized in that: comprise contact base (1), the contact base bottom has the location notch (2) more than 2 or 2, location notch (2) below has the spring groove (3) of circumference type, the alignment pin (5) that reinforcement (4) outside is provided with and location notch (2) number same position is corresponding, reinforcement (4) is fixed on contact base (1) by alignment pin (5) and spring groove (3).
2. the novel contact base of vacuum interrupter with impact absorbing device according to claim 1 is characterized in that: be connected with contact assembly (6) below the described reinforcement (4).
