Abstract
Abstract An end plate for a bobbin comprising a L-shaped piece of an insulating material the first branch of which having a through hole for a core and a number of grooves for connecting wires to windings of the bobbin and the second branch of the end plate having notches for placing soldering tabs, each groove in the first branch emerging into a notch in the other branch, the emerging point having the form of a narrow mouth which the connecting wires pass on their way to the soldering tabs and which after the bobbin windings are completed are closed, thus locking connecting wires to the bottom of the notches.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
End plate for a bobbin, mainly intended for relays, comprising a L-shaped piece of an insulated material, in the first branch of which a through hole for the coil core is arranged as well as a number of grooves for placing connecting wires to windings with which the bobbin is intended to be Provided and in the other branch of which parallel notches are arranged in the longitudinal direction of the branch for placing of soldering tabs, each groove in the first branch emerging into its notch in the other branch, whereby said grooves in the first branch get narrower the closer to the emerging point or mouth they come, said grooves having a mouth width which is considerably smaller than the width of the notches.
