Molded electric parts and method of manufacturing the same

A printed circuit board connector has: an insulating housing (2); SMT type contacts (7, 11) disposed in the insulating housing and spaced apart from each other; and each contact having a lead (11) which extends to a junction surface (2a) of the housing so as to be soldered to a conductive pattern (16) formed on a printed circuit board (15). The lead (11) of each contact is a plating layer (10) formed on the junction surface (2a). The contacts (7) are pin contacts held in place by the insulating housing (2) so as to be electrically connected to the plating layer (10) formed as the leads. The contacts' leads are included in a common plane so that the reliability of electric connection and the durability of connector are improved, and the connector is rendered thinner and more compact to reduce an area required to mount it.

The polymer or a copolymer of trioxane copolymer is manufactured by adding 0.001 to 2.0 wt. % of a stereo-hindering phenol to the monomer mixture in advance to the polymerization step and polymerizing trioxane and an optional co-monomer in the presence of a cationic, active catalyst and said phenol.

Method for manufacturing polymer or copolymer of trioxane

A trioxane copolymer is manufactured by adding to trioxane and a co-monomer, 0.0001 to 2.0 percent by weight, based on the total weight of the monomers, of one or more sterically hindered phenols, then co-polymerizing the resultant mixture in the presence of a cation-active catalyst, and then treating the resultant copolymer by heating it at a temperature which is higher than the melting point of the copolymer to melt the copolymer and decompose and remove unstable parts of the copolymer.
