Electrical plug connector
View Patent ↗An electrical connector includes a connector housing ( 2 ) and a printed circuit board ( 3 ) with two sets of contact elements ( 7, 8 ). The first set of contact elements ( 7 ) is located on the front face of the printed circuit board ( 3 ) and protrudes into an opening in the plug connector housing ( 2 ). The second set of contact elements ( 8 ) is located on the rear face of the printed circuit board ( 3 ). The contact elements of the second set ( 8 ) are configured to form insulation-displacement contacts ( 8 ). The plug connector ( 1 ) also includes a cable manager ( 5 ) which has a continuous opening ( 13 ) and is configured on the front face ( 16 ) with guides ( 19 ) for cores or wires which are intended to make contact with the insulation-displacement contacts ( 8 ). The guides ( 19 ) in the region of the insulation-displacement contacts ( 8 ) are configured with recessed receiving elements or holders ( 20 ) for the insulation-displacement contacts ( 8 ), and the cable manager ( 5 ) can be latched to the plug connector housing ( 2 ).
1. A method for assembly of an electrical plug connector with a plug connector housing, a printed circuit board, a first set of contact elements, a second set of contact elements, the first set of contact elements being arranged on a front face of the printed circuit board and projecting into an opening in the plug connector housing, the second set of contact elements being arranged on the rear face of the printed circuit board, the contact elements of the second set of contact elements being in the form of insulation-displacement contacts and a cable manager with a through-opening, the cable manager being formed on a front face with guides for wire cores which are intended to make contact with the insulation-displacement contacts, the guides in the region of the insulation-displacement contacts being formed with recessed holders for the insulation-displacement contacts, the cable manager being latchable to the plug connector housing, the method comprising the following method steps:
a) inserting the printed circuit board into the plug connector housing;
b) passing the cores of a cable with which contact is to be made through the openings in the cable manager from the rear face to the front face, with the cores being pressed into the associated guides and being cut off at the side edges;
c) aligning the cable manager with respect to the insulation-displacement contacts on the printed circuit board; and
d) pushing on a bracket-like tool, which has a guide edge complementary to an incline on the rear face of the cable manager and has a guide formed parallel to the plug connector housing so that the sliding movement is converted into a travel movement of the cable manager and plug connector housing toward one another, with the insulation displacement contacts making contact with the cores, and the plug connector and the cable manager being latched to one another.
2. A tool for assembly of a plug connector with a plug connector housing, a printed circuit board, a first set of contact elements, a second set of contact elements, the first set of contact elements being arranged on a front face of the printed circuit board and projecting into an opening in the plug connector housing, the second set of contact elements being arranged on the rear face of the printed circuit board, the contact elements of the second set of contact elements being in the form of insulation-displacement contacts and a cable manager with a through-opening, the cable manager being formed on a front face with guides for wire cores which are intended to make contact with the insulation-displacement contacts, the guides in the region of the insulation-displacement contacts being formed with recessed holders for the insulation-displacement contacts, the cable manager being latchable to the plug connector housing, the tool comprising:
an essentially U-shaped part with parallel-running guides arranged on a lower face of limbs, the guides pointing inward and running at right angles to the rear wall of the tool and, in an upper region, the part having an obliquely running guide edge on the inside of each of the limbs.
