Abstract
Abstract The contact elements of the plug connector are engaged into chambers of an insulating strip by means of a conductor terminal component which has cutting and clamping contact edges. The chambers are only open towards a flat side of the strip, so that a conductor can be pressed into the contacting slots of the cutting and clamping contact points from the open side of the chambers. This allows an uncomplicated, orderly connection of the conductor to the contact elements after the connection of the contact elements to the insulating strips. A plurality of such strips can then be inserted into a housing and combined with the latter to form a multi-row, e.g. three or four row, plug connector.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
205 words
A plug connector, comprising: contact elements each having in a longitudinal extension direction at one end a conductor terminal section means for connection to a wire conductor and at an opposite end a contact section means for contact-making with a counter-contact element; an insulating strip having a plurality of U-shaped chambers formed by a base and respective lateral walls, each chamber receiving one of said contact elements; each chamber extending substantially only over a length of the conductor terminal section means of each contact element so as to encompass substantially only the conductor terminal section means and the contact section means of each contact element extending beyond the chamber and free of the strip; said conductor terminal section means comprising at least one contacting slot means into which a respective wire conductor can be inserted from an open side of the chambers for contacting the wire; means interacting with the conductor terminal section means of each contact element for retaining the contact element in the chamber both in a direction perpendicular to the chamber base and in a longitudinal direction of extension of each chamber; and insulating housing means joined to the insulating strip for receiving the free contact section means of each contact element.
Claim 2
Dependent Claim
205 words
A plug connector, comprising: contact elements each having in a longitudinal extension direction at one end a conductor terminal section means for connection to a wire conductor and at an opposite end a contact section means for contact-making with a counter-contact element; an insulating strip having a plurality of U-shaped chambers formed by a base and respective lateral walls, each chamber receiving one of said contact elements; each chamber extending substantially only over a length of the conductor terminal section means of each contact element so as to encompass substantially only the conductor terminal section means and the contact section means of each contact element extending beyond the chamber and free of the strip; said conductor terminal section means comprising at least one contacting slot means into which a respective wire conductor can be inserted from an open side of the chambers for contacting the wire; means interacting with the conductor terminal section means of each contact element for retaining the contact element in the chamber both in a direction perpendicular to the chamber base and in a longitudinal direction of extension of each chamber; and insulating housing means joined to the insulating strip for receiving the free contact section means of each contact element.
Claim 3
Dependent Claim
44 words
A plug connector according to claim 1 wherein said contacting slot means comprises cutting and clamping contact flanks transverse to the chamber lateral walls and wherein said means for retaining comprises a stop projection overlying shoulder portions of the cutting and clamping contact flanks.
Claim 4
Dependent Claim
40 words
A plug connector according to claim 2 wherein said means for retaining further comprises a recess in at least one of the lateral chamber walls and a corresponding projecting section of the contact element at said connector terminal section means.
Claim 5
Dependent Claim
37 words
A plug connector according to claim 1 wherein a plurality of said insulating strips are provided adjacent one another so as to form a stack, the stack being received in a portion of said insulating housing means.
Claim 6
Dependent Claim
40 words
A plug connector according to claim 4 wherein the insulating housing means has a plurality of chambers for receiving the contact section means of each contact element, and means for locking the plurality of insulating strips in the insulating housing.
Claim 7
Dependent Claim
45 words
A plug connector according to claim 1 wherein the conductor terminal section means comprises first and second bent sections of the contact element which are transverse to said longitudinal extension direction of each contact element and wherein each bent section has a contact slot therein.
Claim 8
Dependent Claim
211 words
A plug connector, comprising: contact elements each having in a longitudinal extension direction at one end a conductor terminal section means for connection to a wire conductor and at an opposite end a contact section means for contact-making with a counter-contact element inserted into said contact section means in said longitudinal extension direction; an insulating strip having a plurality of U-shaped chambers formed by a base and respective lateral walls, each chamber receiving one of said contact elements; each chamber extending substantially only over a length of the conductor terminal section means of each contact element, and the contact section means of each contact element extending beyond the chamber and free of the strip; said conductor terminal section means comprising at least one cutting and clamping contact flank having a contacting slot means into which a respective wire conductor can be inserted in said longitudinal extension direction from an open side of the chambers for contacting the wire; stop projection means on the chamber walls for retaining the contact element in the chamber in a direction perpendicular to the chamber base and in a longitudinal direction of extension of each chamber; and insulating housing means joined to the insulating strip for receiving the free contact section means of each contact element.
Claim 9
Dependent Claim
211 words
A plug connector, comprising: contact elements each having in a longitudinal extension direction at one end a conductor terminal section means for connection to a wire conductor and at an opposite end a contact section means for contact-making with a counter-contact element inserted into said contact section means in said longitudinal extension direction; an insulating strip having a plurality of U-shaped chambers formed by a base and respective lateral walls, each chamber receiving one of said contact elements; each chamber extending substantially only over a length of the conductor terminal section means of each contact element, and the contact section means of each contact element extending beyond the chamber and free of the strip; said conductor terminal section means comprising at least one cutting and clamping contact flank having a contacting slot means into which a respective wire conductor can be inserted in said longitudinal extension direction from an open side of the chambers for contacting the wire; stop projection means on the chamber walls for retaining the contact element in the chamber in a direction perpendicular to the chamber base and in a longitudinal direction of extension of each chamber; and insulating housing means joined to the insulating strip for receiving the free contact section means of each contact element.
