Specific embodiment
For the ease of the understanding of those skilled in the art, below with reference to examples and drawings 1-6 to the utility model make into
The explanation of one step, the content that embodiment refers to not are the restriction to the utility model.
As shown in figures 1 to 6, a kind of shell for electromagnetic relay including shell 01 and is located in the pedestal of shell 01
02, the pedestal 02 includes pedestal 021, mounting base 022 and coil axis 023, and the both ends of the coil axis 023 are separately connected
The pedestal 021 and mounting base 022, the mounting base 022 are provided with installation part 09, and the installation part 09 is offered for limiting
The limiting slot 092 of the static contact spring piece of electromagnetic relay.
A kind of shell for electromagnetic relay of the utility model is arranged installation part 09 in mounting base 022, then opens up
Limiting slot 092 prevents the static contact spring piece of electromagnetic relay from deforming so that the static contact spring piece of electromagnetic relay is defined in limiting slot 092, protects
It is constant to have demonstrate,proved the distance between movable contact and stationary contact, has saved electricity, the utility model structure is simple, and design rationally, mentions significantly
The service life of high electromagnetic relay.
The installation part 09 is also provided with accommodation groove 091, the production when accommodation groove 091 is for collecting electromagnetic relay work
Raw dust.
In the present embodiment, the accommodation groove 091 is used for the electrical contact of the static contact spring piece and movable contact spring and generates oxidate powder
The collection of dirt avoids oxide powder dust from accumulating and influence the insulating capacity and performance of electromagnetic relay in the pedestal 02.
The shell 01 offers venthole 012.
In the present embodiment, the venthole 012 be used for balanced electromagnetic relay and atmosphere pressure, meanwhile, because electromagnetism after
Heat can be generated when electrical work, needed to radiate by the venthole 012, avoided crossing cause thermal damage because of electromagnetic relay；
Further, the venthole 012 is set to the top of the shell 01.
The pedestal 021 offers the open ports 03 of the movable contact spring for being clamped electromagnetic relay.
In the present embodiment, by opening up the open ports 03 in the pedestal 021, the pedestal 02 is in assembling movable contact spring
When, movable contact spring can be directly incorporated into the open ports 03, and structure is simple, and it is easy to assembly, packaging efficiency is improved, is avoided in existing skill
It misplaces when movable contact spring needs to be inserted into existing spring leaf hole from top to bottom in art and movable contact spring is lost.
