Description
Technical field
The utility model relates to switching technique fields, more particularly to a kind of sealing slot structure of switch.
Background technique
Switch is widely used in the control circuit of various equipment, in order to seal internal structure, to prevent outside
The influence to inner components of water, humidity, usually need to realize sealing with plastic packaging glue in the switch.
A kind of sealing slot structure of switch of the prior art is that plastic packaging glue is arranged in the inside of switch, will by plastic packaging glue
The components such as the auxiliary section of the movable contact of contact-carrying movable contact spring, the stationary contact of contact-carrying static contact spring piece and driving part are sealed in switch
Interior, driving part can be moved with movable contact movable contact spring, make the movable contact of contact-carrying movable contact spring and the stationary contact of contact-carrying static contact spring piece
Point is switched on or switched off.Fig. 1 is a kind of sealing slot structure of switch of the prior art comprising pedestal 100 and cover board 200, the bottom of at
Seat 100 is equipped with glue groove 101, and since plastic packaging glue is the inside for being located at switch, glue groove 101 to be usually arranged long, is covering
Plate 200 is additionally provided with a gum-injecting port 201, is first cover board 200 to be attached on pedestal 100, and make gum-injecting port 201 and pedestal when sealing
100 glue groove 101 is connected, and then injects glue 300 in the glue groove 101 of pedestal 100 by the gum-injecting port 201 of cover board 200, this
The sealing slot structure of kind switch will make glue 300 full of glue groove 101 because glue groove 101 is longer, need to increase injecting glue pressure in injecting glue
Power is not only difficult to operate, and is easy that glue is made to leak into switch internal.Fig. 2 is the sealing of another switch of the prior art
Slot structure comprising pedestal 400 and cover board 500 are equipped with glue groove 401 on pedestal 400, are the glue first to pedestal 400 when sealing
Slot 401 injects glue 600, then cover board 500 is attached on pedestal 400 again, the sealing slot structure of this switch, due to being first to infuse
Glue, therefore, glue cannot be infused too full, completely in this way, it is insufficient to will result in injecting glue amount, will will lead to lid inside fluid flow switch very much
There is no glue on plate, to influence sealing effect.
Utility model content
The purpose of the utility model is to overcome the deficiencies of the prior art, provide a kind of sealing slot structure of switch, pass through
Structure is improved, and glue can either be avoided when injecting glue to flow to switch internal, and from need not increasing injection pressure, and have it is easy to operate, it is close
Seal the good feature of effect.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of sealing slot structure of switch, including
Pedestal and cover board；The pedestal be equipped be used to accommodate the movable contact of contact-carrying movable contact spring, the stationary contact of contact-carrying static contact spring piece and
The chamber of the auxiliary section of driving part is equipped on the side of chamber and is used to injecting glue to realize the glue groove to cavity seal；The lid
Plate is on pedestal；In the cover board, in the glue groove position for corresponding to pedestal, squeezed equipped with what at least one extended to pedestal direction
Jiao Tai；When cover board is matched with pedestal, the plastic squeeze platform is reached in the glue groove of pedestal.
The plastic squeeze platform is in reduce gradually by root terminad.
The root of the plastic squeeze platform is additionally provided with boss compatible with the shape of glue groove.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is due to using in cover board, in the glue groove position for corresponding to pedestal, is equipped at least one the bottom of to
The plastic squeeze platform that seat direction extends；When cover board is matched with pedestal, the plastic squeeze platform is reached in the glue groove of pedestal.The utility model
This structure be that first glue is injected into the glue groove of pedestal, after cover board is assembled to pedestal, the plastic squeeze platform of cover board reaches bottom
In the glue groove of seat, the glue in pedestal glue groove can be pushed to cover board, to realize what glue was surrounded the glue groove of pedestal and cover board
Space is full of, and has the function that sealing, glue when injecting glue can either be avoided to flow to switch internal, and from need not increasing injection pressure, and
With easy to operate, the good feature of sealing effect, and it is of less demanding to the mobility of glue.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But one kind of the utility model is opened
The sealing slot structure of pass is not limited to the embodiment.
