Abstract
Abstract An electrical terminal having a housing formed of an insulating material and at least one clamping body having an opening for the reception of at least one conductor. At an open flat side of the insulating housing there is arranged at least one insert element formed of insulating material and forming a pocket receiving a blocking flap which prevents the introduction by mistake of a conductor externally of the clamping body into the insulating housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
176 words
An electrical terminal comprising a substantially flat insulating housing provided with recesses open towards one of its flat sides, at least one clamping device arranged in the housing for fixedly clamping at least one electrical conductor, said clamping device comprising a stationary contact element and a clamping body provided with an opening for the reception of said at least one conductor, a clamping screw, the clamping body being movable by means of the clamping screw in a direction substantially perpendicular to the contact element, the contact element extending into the opening of the clamping body, said opening including a conductor infeed mouth, a blocking flap extending in a direction away from the contact element provided at the conductor infeed mouth of the opening of the clamping body for preventing the mistaken introduction of a conductor externally of the clamping body into the insulating housing, at least one insert element formed of insulating material arranged at the open flat side of the insulating housing, said insert element forming a pocket for the reception of the blocking flap.
Claim 2
Dependent Claim
176 words
An electrical terminal comprising a substantially flat insulating housing provided with recesses open towards one of its flat sides, at least one clamping device arranged in the housing for fixedly clamping at least one electrical conductor, said clamping device comprising a stationary contact element and a clamping body provided with an opening for the reception of said at least one conductor, a clamping screw, the clamping body being movable by means of the clamping screw in a direction substantially perpendicular to the contact element, the contact element extending into the opening of the clamping body, said opening including a conductor infeed mouth, a blocking flap extending in a direction away from the contact element provided at the conductor infeed mouth of the opening of the clamping body for preventing the mistaken introduction of a conductor externally of the clamping body into the insulating housing, at least one insert element formed of insulating material arranged at the open flat side of the insulating housing, said insert element forming a pocket for the reception of the blocking flap.
Claim 3
Dependent Claim
49 words
The terminal as defined in claim 1, wherein the insert element comprises a substantially strip-shaped projection extending in the direction of the clamping screw, said projection forming along the open side of the insulating housing a boundary of the conductor infeed mouth of the opening of the clamping body.
Claim 4
Dependent Claim
40 words
The terminal as defined in claim 2, wherein a part of the insert element forms said pocket and said part and an end portion of the projection which faces away from such part are each anchored in the insulating housing.
Claim 5
Dependent Claim
44 words
The terminal as defined in claim 1, wherein the insert element is mounted in a recessed fashion in the insulating housing in such a manner that its outer surface and the open flat side of the housing are substantially located in a common plate.
Claim 6
Dependent Claim
18 words
The terminal as defined in claim 4, wherein the insert element is lockingly engaged in the insulating housing.
Claim 7
Dependent Claim
67 words
The terminal as defined in claim 1, wherein two of said clamping devices of similar construction are arranged in mirror-image relationship to one another in the insulating housing, said contact element being common to both said clamping devices, one such insert element is respectively provided for each of the clamping devices, a connection web for mechanically connecting both insert elements with one another into a structural unit.
Claim 8
Dependent Claim
23 words
The terminal as defined in claim 6, wherein the two insert elements and the connection web consist of a single piece of material.
Claim 9
Dependent Claim
54 words
The terminal as defined in claim 6, wherein the two insert elements and the connection web are arranged recessed in the insulating housing in such a manner that the outer surface of the insert elements and the connection web and the open flat side of the housing are substantially located in a common plane.
Claim 10
Dependent Claim
28 words
The terminal as defined in claim 8, wherein the structural unit composed of the two insert elements and the connection web are lockingly engaged in the insulating housing.
Claim 11
Dependent Claim
109 words
An electrical terminal comprising a housing, at least one clamping device supported in the housing for fixedly clamping at least one electrical conductor, said clamping device comprising a stationary contact element and a clamping body provided with an opening for the reception of said at least one conductor, the contact element extending into the opening of the clamping body, a blocking flap provided at the opening of the clamping body for preventing the mistaken introduction of a conductor externally of the clamping body into the housing, at least one insert element arranged at the insulating housing, said insert element forming a pocket for the reception of the blocking flap.
Claim 12
Dependent Claim
109 words
An electrical terminal comprising a housing, at least one clamping device supported in the housing for fixedly clamping at least one electrical conductor, said clamping device comprising a stationary contact element and a clamping body provided with an opening for the reception of said at least one conductor, the contact element extending into the opening of the clamping body, a blocking flap provided at the opening of the clamping body for preventing the mistaken introduction of a conductor externally of the clamping body into the housing, at least one insert element arranged at the insulating housing, said insert element forming a pocket for the reception of the blocking flap.
