FIELD: electrical engineering. SUBSTANCE: gear making secure set of batteries and radio telephone presents cast member. Cast member includes rear wall of enclosure of radio telephone, two rails over which casing with batteries slide along guides for subsequent registration in radio telephone. Four or six guides are made on principle of flexible deformation. flexible guides have U-shaped form and are joined to rails. Channel is cut in rail under smooth guides for their possible departure (bending). Departure of guides takes place under action of terminals of set of batteries at moment of complete insertion of the latter. Departed guides act on set of batteries with calculated force. This force ensures high quality of contact between leads-out of set of batteries and leads-out of radio telephone. EFFECT: high quality of contact between leads-out of set of batteries and radio telephone. 10 cl, 8 dwg
