Construction for mounting a terminal, a circuit board connector and method of mounting it

A circuit board connector, comprising:

• a housing (11) configured for mounting to a circuit board (40);
• terminals (20) mounted into the housing (11), each of said terminals (20) having at least one resilient contact (27) projecting from the housing (11) and configured for insertion along an insertion direction (ID) into a corresponding hole (41) in the circuit board (40) and a jig contact (29) bulging out at an angle to the inserting direction (ID) behind the resilient contacts (27) with respect to the inserting direction (ID), each said jig contact (29) having a length (L) along the insertion direction (ID);
• and
• a positioning plate (50) assembled with the housing (10) and having insertion holes (51) into which the jig contacts (29) of the terminals are inserted, the insertion holes (51) each having a depth (D) at least equal to the length (L) of the jig contacts (29) of the terminals (20).

A method for mounting a circuit board connector (10) to a circuit board (40), comprising the following steps:

• providing a housing (11) with terminals (20) having resilient contacts (27) for insertion along an insertion direction (ID) into corresponding holes (41) in the circuit board (40) and a jig contact (29) bulging out at an angle to the inserting direction (ID) from a location behind the respective resilient contact (27) with respect to the inserting direction (ID), each said jig contact (29) having a rear edge (29A) and a front edge (29B) defining a length (L) for the jig contact (29) along the insertion direction (ID);
• providing a positioning plate (50) with front and rear surfaces and insertion holes (51) extending therebetween, the insertion holes (51) having depths (D) at least equal to the lengths (L) of the jig contacts (29);
• inserting the terminals (20) into insertion holes (51) of the positioning plate (50) so that the rear edges (29A) of the jig contacts (29) are substantially flush with the rear surface of the positioning plate (50) and so the resilient contacts (27) project beyond the front surface of the positioning plate (50);
• and
• pressing the rear edges (29A) of the jig contacts (29) and the rear surface of the positioning plate (50) by a jig (60) to press the resilient contacts (27) into the holes (41) of the circuit board (40) and to position the front surface of the positioning plate (50) substantially against the circuit board (40), whereby the front edges (29B) of the jig contacts (29) are prevented from damaging contact with the circuit board (40).
