Embodiment 1

[0024] Embodiment one: if figure 1 with figure 2 As shown, a tool for assembling an arc extinguishing chamber includes a bottom plate 1 and an arc extinguishing blade positioning plate 2 . The arc extinguisher positioning plate 2 is a plate-like structure placed horizontally. There is a long strip-shaped and inclined guide hole 21 in the middle of the arc extinguisher positioning plate 2. There are several card slots 22 at the front end of the arc extinguisher positioning plate 2. The front end A limit step 23 is provided below. The width of each slot 22 and the arrangement of the slots 22 correspond to the arc extinguishing plates 31 in the arc extinguishing chamber 3 one by one. The center of the bottom plate 1 is provided with an arc extinguishing chamber assembly area 11 , and four corners are provided with fixing holes 15 . The arc extinguishing chamber assembly area 11 is provided with a positioning mechanism for limiting the movement of the left arc extinguishing co...

Abstract

The invention discloses an arc extinguish chamber assembling tool. The arc extinguish chamber assembling tool comprises a bottom plate and an arc extinguish piece positioning plate; a guide hole is formed in the middle of the arc extinguish piece positioning plate; clamping grooves are formed in the front end of the arc extinguish piece positioning plate, and a limiting step is arranged below the front end of the arc extinguish piece positioning plate; an arc extinguish chamber assembling area is arranged in the center of the bottom plate and is provided with a positioning mechanism; a limiting baffle and a guide pin are fixedly arranged behind the arc extinguish chamber assembling area; the arc extinguish piece positioning plate is located above the bottom plate and is in sliding connection with the bottom plate, the limiting baffle is located in front of the limiting step, the guide pin is arranged in a guide hole, and when the arc extinguish piece positioning plate is pushed forwards, the front end of the arc extinguish piece positioning plate can stretch into an arc extinguish chamber from the open end of the assembled arc extinguish chamber, and when the rear surface of the limiting baffle is in abut joint with the front surface of the limiting step, arc extinguish pieces are correspondingly clamped in the clamping grooves. The assembling tool is convenient to operate, safe, reliable, and capable of reducing the labor intensity and improving the assembling efficiency and the one-time yield.

Description

technical field [0001] The invention belongs to the technical field of arc extinguishing chamber assembly, and in particular relates to an arc extinguishing chamber assembly tool. Background technique [0002] When the high-voltage relay is opened, since the gap between the two contacts is small to large during the process of the contact from contact to separation, under the action of high voltage, the insulating medium in the gap will be ionized and broken down, forming an arc. After the arc is formed, the heat generated will further aggravate the ionization of the medium, expand the arc, and make the circuit breaker unable to disconnect the circuit. There are many channels inside the chamber, one is to split the arc, and the other is to use the high-pressure airflow generated by the high temperature of the arc to extinguish the arc through a certain channel nozzle in the arc extinguishing chamber. [0003] At present, the arc extinguishing chamber assembled in the market ...
