Abstract
The plug in U.S. Pat. No. 4,165,995 is improved as to the contact carrier by providing slots in an orientation so that thermocouple leads can be laterally inserted before hanging over ridges for contact-making with annular contacts of a socket member in the holder. The orientation of the slots permits lateral placement of the thermocouple leads through the ridges, but the leads will hang over them in a location azimuthally offset from the slot through the respective ridge.
Claims8
A plug connector between a thermocouple and a tubular holder for the thermocouple and including a socket member mounted to one end of the tubular holder and defining an opening;
- at least one annular contact mounted in the opening of the socket member, the thermocouple being mounted on a carrier from which extend two leads of the thermocouple, the improvement comprising:
- a contact carrier on said thermocouple carrier made of electrically insulating material and being mounted to the thermocouple carrier and having at least one annular rib of radially outwardly tapered contour, the rib having an outer diameter slightly larger than an inner diameter of the annular contact;
- at least one axially extending, radially inwardly narrowing first slot in the contact carrier, interrupting the annular rib, one of the leads being inserted through the first slot to lodge in a bottom duct of said first slot;
- and
- means defining a second slot in the contact carrier, above the first slot but being contiguous with a narrowed portion of said first slot and ending in the outer periphery of the carrier, above said rib and azimuthally offset from said first slot where interrupting the rib, for receiving one lead so that this lead can hang over the rib and engages the contact upon insertion of the carrier into the socket.
A contact carrier for connection to a thermocouple carrier from which extends at least one lead and for insertion in a socket having at least one annular contact, the combination comprising
- the contact carrier being of cylindrical construction, having a first axial end face for abutment with the thermocouple carrier and a second axial end face, there being a radial groove in the second end face;
- an axial duct traversing the contact carrier and having an entrance opening at a location from which the lead extends from the thermocouple carrier, and ending at its other end in the radial groove;
- a slot extending laterally from the groove;
- an annular rib on and around the cylindrical carrier, the lead being inserted in the duct axial bore and running through the lateral slot, the lead hanging over the rib;
- and
- means for fastening carriers to each other.
A contact carrier for connection to a thermocouple carrier from which extends at least one lead and for insertion in a socket having at least one annular contact, the combination comprising:
- the contact carrier being of cylindrical construction, having a first axial end face for abutment with the thermocouple carrier and a second axial end face, there being a radial groove in the second end face;
- a first slot in the contact carrier, extending in radial direction as well as axially from the radial groove to the first axial end face, the lead being received by the first slot;
- a second slot in the contact carrier, extending obliquely to an axis of the contact carrier as well as to a radial direction from an axial level corresponding to a bottom of the radial groove and toward the second end face, and communicating with the first slot;
- and
- an annular rib, being interrupted by the first slot and extending in an axial level away from the bottom toward the first end face.
