The battery pack retention apparatus, described herein, is an injection molded part. The injection molded part includes a rear housing (200) for a radiotelephone (100), two rails, (201, 203) for a battery pack (101) to slide along and six guide bars (207, 209, 211, 213, 215, 217) for retaining the battery pack (101) on the radiotelephone (100). Four of the six guide bars are the compliance type. The compliance-type guide bars (207, 211, 213, 217) have a U-shape and are coupled to the rails. A channel (401) is cored out from the rails under the compliance-type guide bars to allow for deflection of the guide bars. Deflection is caused by the bullets (409) of the battery pack (101) when the battery pack (101) is fully inserted. The deflection (y) of the guide bars provides a calculated force upon the battery pack (101). This calculated force ensures a high quality electrical connection between the contacts of the battery pack and the contacts of the radiotelephone.

Dispositif de maintien de bloc-piles constitué d'une pièce moulée par injection. Cette dernière comporte un logement arrière (200) conçu pour un radiotéléphone (100), deux rails (201, 203) permettant à un bloc-piles (101) de glisser et six barres de guidage (207, 209, 211, 213, 215, 217) servant à maintenir le bloc-piles (101) sur le radiotéléphone (100). Quatre des six barres de guidage sont souples. Les barres de guidage souples (207, 211, 213, 217) sont en U et reliées aux rails. Un profilé (401) est obtenu par découpage des rails sous les barres de guidage souples pour permettre la déviation des barres de guidage. Cette déviation est provoquée par les ergots (409) du bloc-piles (101) lorsque celui-ci est entièrement inséré. La déviation (y) des barres de guidage fournit une force calculée sur le bloc-piles, cette force calculée assurant une connexion électrique de qualité élevée entre les contacts du bloc-piles et les contacts du radiotéléphone.
