A circuit board electrical connector includes a housing (10); a plurality of contact elements (25) arranged in the housing; a receiving recess (23) provided in the housing for receiving a circuit board (1) such that contact pads (2) of the circuit board are brought into contact with the contact elements; an ejector (40) provided on the housing for ejecting the circuit board so as to release the contact between the circuit board and the contact elements; a slide portion (41) provided on the ejector and having an action face (49) at a lower end thereof; a finger portion (42) provided on the ejector and having a bearing face (46) for abutting action face to receive a pushing force from the slide portion for rotation to lift the circuit board; and fulcrum means (26) provided in the housing for support the finger portion between bearing face and a front end for rotation.

An unsaturated polyester composition for molding compounds, consisting essentially of (1) 20 to 70 parts by weight of an unsaturated polyester obtained by condensing an acid component comprising a major amount of an .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid with a polyol, (2) 25 to 75 parts by weight of a vinyl monomer copolymerizable with said unsaturated polyester, (3) 1 to 25 parts by weight of a thermoplastic polymer, and (4) at least one member selected from the group consisting of hydroxyl-containing vinyl monomers and epoxy-containing vinyl monomers in a ratio of 1 to 40 parts by weight to 100 parts by weight of said unsaturated polyester (to form 100 parts by weight of the composition). The composition may be molded and cured to yield articles which provide good adhesion to surface coatings and are susceptible of decorative finishes.
