Wound Connector Multiple Contact
This article describes a multi-contact connector in which a wire is wound in
the grooves of a non-conductive material.
Such a connector, which can be fabricated at relatively low
cost, is constructed as follows: The connector consists of a body 10
molded or machined from a non-conductive material, such as plastic,
with spiral grooves 11 wound at a fixed pitch around the body,
allowing the continuous winding of a wire 13 within the grooves as
the body is rotated. Each turn of the wire may be formed and/or cut
after winding to make each of the turns such as conductor 15 an
independent contact. The wire is retained in its respective groove
both before and after cutting by an adhesive 17 (Fig. 2) and after
cutting by forming the individual turns into individual contact
areas, such as 19, 21 (Fig. 2). The contact material may be round
or rectangular with spring characteristics to provide contact
pressure and may be coated or plated to improve corrosion resistance.
Aligning pins 23 may be molded as part of the connector on one or
Referring now to Fig. 2, after the contact wire has been wound and formed
onto the connector body to provide the desired number of contacts, a cutting and
forming tool 25, such as shown schematically, is applied to sever the individual
windings which are then removed to provide a contact configuration of the type
illustrated in Fig. 2. The above device represents a simple method of forming a
