Surface-mountable thermocouple connector with reverse polarity protection
A connector to easily and correctly join an electrical component to a printed circuit board is provided. The connector comprises a generally C-shaped electrically conductive element that provides for connection alternatively to the positive and negative terminals of a device depending on the orientation of the connector. As a result of the shapes of the ends of the connector, a device can only be plugged in one way. The connector can be made from a single sheet of electrically conductive material bent generally into a “C” shape, with specific tabs and cuts made therein. The connector includes a tab that allows for quick and automated connection to a printed circuit board, and an element to prevent connectors from interlocking while in a loose and unconnected state as, during manufacturing, plating, or storage, allowing them to be added to a board using automated procedures for quick, accurate and low cost construction.
1. A connector element for connecting to a printed circuit board, so as to enable the connection of a separate electric device to the circuit board, the connector element comprising:
one piece element of a single sheet of electrical conductive material formed so as to have an elongated axis and have a first end, a second end and a central section therebetween, the central section comprising a tubulated element have a generally C-shaped cross section, the first end being configured to insert, in electronic connectivity, only a positive electrical prong therein and the second end being configured to insert, in electronic connectivity, a negative electrical prong therein;
the tubulated element of the center section further includes a tab extending generally perpendicular to a bottom wall and other tab extending from a top wall adapted for creating a quick attachment guide for electronically and physically attaching a surface mountable (SMT) temperature sensor connector element to a printed circuit board with either the first end or the second end, as desired, in a prong insertion direction.
2. The connector element of claim 1 , wherein the one piece element of the single sheet of electrical conductive material is made of beryllium-copper and is plated with nickel.
3. The connector element of claim 1 , wherein the one piece element of the single sheet of electrically conductive material is folded into a generally C-shaped form.
4. The connector element of claim 1 , wherein the one piece element further comprises two electrical connectors placed in a generally parallel relationship, in a reverse axis configuration, to form a junction socket for an electrical device.
5. The connector element of claim 4 , where the placement of the two connector forms a poka-yoke connection for polarity protection.
6. The connector element of claim 4 , wherein the two electrical connectors are in a poka-yoke relationship, for reverse polarity protection, and are in electrical connection with the printed circuit board, such that the negative prong of a plug cannot be inserted into the positive end of the tubulated element.
7. The connector element of claim 1 , wherein the one-piece element further comprises the other tab, projecting out from the top of the tubulated element, generally perpendicular to the elongated axis, to prevent two or more tubulated elements from inter-tangling with each other.
