An antenna device for portable communication equipment and comprising an extendable elongated antenna element which at its lower part comprises a peg element and which is slidable inside a sleeve member between an extended position, where the peg element is mechanically locked in the sleeve member and where simultaneously conductive contact between the sleeve member and an antenna rod is established via the peg element, and a retracted position where the peg element is free from the sleeve member,
- said sleeve being rigid, and
- said peg element being provided with a resilient portion including an engagement portion have a contact surface which in the extended position of the elongated antenna element exerts a locking force against the sleeve member,
- said engagement portion being provided on a free end of the peg element,
- said sleeve member on the inside being provided with an abutment for cooperation, in the extended position of the elongated antenna element, with a corresponding shoulder comprised on the peg element,
- wherein the engagement portion includes engagement elements, each being provided on an axially extended spring acting shank element.
A peg element for fastening to the lower part of an extendable elongated antenna element and having an engagement portion at its free and opposite the position of a fastened antenna rod,
- said peg element being provided with a resilient portion including the engagement portion which has a contract surface which in the extended position of the elongated antenna element is intended to exert a locking force against the inside of a substantially rigid sleeve member,
- said peg element being provided with a shoulder for cooperation, in the extended position, with a corresponding abutment inside the sleeve member,
- said engagement portion being provided on a free end of the peg, element, and including engagement elements, each being provided on an axially extended spring acting shank element, and
- wherein the shoulder is located between the contact surface and an upper part which comprises a hole for receiving the antenna rod.
An antenna device for portable communication equipment comprising:
- an elongated antenna element having upper and lower portions,
- a sleeve member through which said elongated antenna element is axially slidable between an extended and a retracted position,
- said sleeve including a generally cylindrical conductive feed portion,
- said antenna element having at said lower portion a conductive peg element for electrically and frictionally engaging said conductive feed portion when said antenna element is in its extended position, and the electrical and frictional engagement being broken by the peg element being free of the sleeve when retracted,
- said peg element being provided with an antenna element connection portion and a resilient portion formed in said peg element by at least one bifurcating slot in parallel with a longitudinal axis of the peg element,
- said resilient portion having at least one engagement portion with a contact surface,
- said electrical and frictional engagement being achieved by said contact surface exerting a contact force against said feed portion,
- said engagement portion being provided on a free end of the peg element, and
- wherein the engagement portion includes at least one engagement element which is provided on an axially extended spring acting shank element.
