Insulating body for screw and crimp contacts

An insulating body, comprising:

• a contact carrier (1, 1′);
• and
• a holding plate (3, 3′) which can be latched to the contact carrier (1, 1′),
• wherein the contact carrier (1, 1′) has
• two mutually opposite longitudinal sides (11, 11′) oriented in a longitudinal direction of the insulating body and
• two mutually opposite narrow sides (12, 12′) oriented perpendicularly thereto,
• a cable connection side (13, 13′), and
• a plug-in side (14, 14′),
• wherein the contact carrier (1, 1′) has contact chambers (100, 100′) which, running in a plug-in direction, connect the cable connection side (13, 13′) to the plug-in side (14, 14′),
• wherein a first group of contact chambers (100, 100′) is arranged close to a first of the longitudinal sides (11, 11′), and
• wherein a second group of contact chambers (100, 100′) is arranged close to a second of the longitudinal sides (11, 11′), and
• wherein the contact chambers (100, 100′) of the first group and the contact chambers (100, 100′) of the second group are arranged offset from one another in the longitudinal direction, whereby the first of the longitudinal sides (11, 11′) is a proximal longitudinal side and the second of the longitudinal sides (11, 11′) is a distal longitudinal side for each of the contact chambers (100, 100′) of the first group, and vice versa the first of the longitudinal sides (11, 11′) is the distal longitudinal side and the second of the longitudinal sides (11, 11′) is the proximal longitudinal side for each of the contact chambers (100, 100′) of the second group,
• wherein the contact chambers (100, 100′) are cylindrical at their plug-in-side end, and
• wherein the contact chambers (100, 100′) have, at their cable-connection-side end, in addition to their cylindrical shape, in each case include a screw connection receptacle (180, 180′) which adjoins the end laterally and which points in the direction of the distal longitudinal side (11, 11′) and which, for fixing and contacting on the cable connection side a screw contact (4) inserted or to be inserted into the contact chamber (100, 100′) by a contact screw (47) through a screw bushing (170) running in the direction of the distal longitudinal side (11, 11′), is open towards this distal longitudinal side (11, 11′), and
• wherein the holding plate (3, 3′) has a substantially rectangular base plate (33, 33′) on which two side plates (31, 31′) are integrally molded longitudinally opposite one another and pointing in a common direction,
• wherein latching elements (311, 311′) are arranged in each of the two side plates (31, 31′) for the latching of the holding plate (3, 3′) to the contact carrier (1, 1′),
• wherein each of the latching elements (311, 311′) includes an arm extending between two slots from a distal end of a respective one of the two side plates (31, 31′) towards the substantially rectangular base plate (33, 33′), and an inwardly protruding latching portion (318) formed at a free end of the arm,
• wherein the latching elements (311, 311′) in the two side plates (31, 31′) are offset from one another,
• wherein the base plate (33, 33′) in a latched state comes to lie on the cable connection side (13, 13′) of the contact carrier (1, 1′), and
• wherein contact bushings (30, 30′) are arranged in the base plate (33, 33′) which, in the latched state, are arranged above respective contact chambers (100, 100′),
• wherein the base plate (33, 33′), in the latched state, engages with a latching arm (38) arranged at its contact bushings (30, 30′) into the screw connection receptacle (180, 180′) of the corresponding contact chamber (100, 100′) of the contact carrier (1, 1′) in order to fix a crimp contact (5) inserted or to be inserted into the contact chamber (100, 100′).
