Bonding between body is firm, so that the tensile strength between steel pin and glass body is high.
Technical solution adopted in the utility model is：A kind of glass cap and pin insulator is provided, it includes the glass of plate-like
Body, the center of glass body forms connecting portion axially towards upper evagination, is provided with chapeau de fer above glass body, chapeau de fer with
Connecting portion is fixed, and steel pin is provided with below glass body, it is characterised in that：Connection is located on the lower surface of described glass body
Portion position is recessed mounting groove, and the upper end of steel pin is placed in mounting groove, is provided with main running channel in the steel pin and backflow is poured
Road, the end face that steel pin is located in mounting groove is provided with the cast gate being connected with main running channel, and steel pin is located on the outer wall in mounting groove
Multiple backflow imports are provided with, backflow import is connected by the branch pipe in steel pin with backflow running channel respectively, and steel pin exposes to mounting groove
Lateral wall be provided with bypass outlet, bypass outlet is connected with backflow running channel, and the steel instep sets on the lower surface of mounting groove
There is the supply opening for supplying main running channel liquid glue, liquid glue is in steel when liquid glue is flowed into mounting groove through main running channel
Interior cementing layer is solidify to form between the lateral wall of pin and the madial wall of mounting groove.
It is radially spaced on end face where being located at steel pin on glass body to be provided with interior full skirt, middle full skirt and exumbrella
Skirt.
Outer cementing layer is provided between described chapeau de fer and the lateral wall of connecting portion.
After using above structure, glass cap and pin insulator of the present utility model has advantages below compared with prior art：
Running channel is set on steel pin can make liquid glue water from mounting groove toward exosmosis, between thereby guaranteeing that between steel pin and mounting groove
Glue is full of in gap, firmly, intensity is high for its bonding process.
