Abstract
A surface mount header is shown which may be mounted to a surface of a printed circuit board, where pins project away from the board. Alternatively, the surface mount header may be connected to a surface of a printed circuit board with the pins projecting downwardly through an opening in the board. Insulative sleeves surround the pins in order to protect the pins from contact with conductive paths within the board.
Claims19
An electrical connector, comprising:
- an electrical connector housing body portion;
- a plurality of substantially flat electrical contacts, each being comprised of a contact portion formed by a single pin and an electrical connection device adapted for surface mount soldering engagement with at least one electrical circuit board trace, each electrical connection device being comprised of first and second surface mount soldering contact surfaces on a contact member where the electrical connection devices are substantially the same width as the corresponding contact portions, and the plurality of electrical contacts are held in laterally aligned position by the housing body portion, the contact member being dimensioned with a fixed thickness between the first and second contact surfaces where the fixed thickness is greater than a distance between extreme surfaces of the housing body portion the first contact surfaces being positioned in a plane spaced from said second contact surfaces, the electrical connection devices being alternatively connectable to either the first or second contact surfaces.
An electrical connector having alternative mounting arrangements, comprising:
- an electrical connector housing, having a housing body portion;
- a plurality of electrical contacts positioned in the housing body portion, whereby the plurality of electrical contacts are directly attached to the housing body portion with each electrical contact being comprised of at least one pin and at least one electrical connection device, each electrical contact being flat and defining two major parallel surfaces, each electrical contact further comprising a contact portion extending from the electrical connector housing, with the plurality of contacts lying in parallel planes, whereby the plurality of electrical contacts are adapted for mating engagement with a plurality of electrical circuit board traces, wherein each electrical connection device is comprised of first and second contact surfaces defined on opposite ends of the contact portion and spaced apart by a thickness greater than a thickness of the electrical connector housing;
- said electrical connection devices being connectable to a circuit board in a plurality of configurations, where the circuit board has first and second oppositely facing surfaces wherein said plurality of configurations include:
- a first configuration wherein the first contact surface of said electrical connection devices is surface mounted to a first surface of a circuit board with the pins projecting away from the board;
- and
- a second configuration wherein the second contact surface of said electrical connection devices is surface mounted to a first surface of the circuit board, and said pins project through the circuit board and are electrically isolated from the second surface.
3 more elements
An electrical connector, comprising:
- an electrical connector housing having a housing body portion;
- a plurality of electrical contacts cooperating together with the housing body portion such that the electrical contacts are attached to said housing body portion, and each electrical contact being comprised of a pin and an electrical connection device having at least one contact portion adapted for surface mount engagement with at least one electrical circuit board trace, wherein each electrical connection device is comprised of first and second contact surfaces defined on opposite ends of the contact portion and spaced apart by a thickness greater than a thickness of the electrical connector housing;
- an electrically insulative sleeve surrounding said pin, whereby said electrical connection device is adapted for surface mounting to a surface of a circuit board, and with said pins projecting through a through opening of the circuit board, with said electrically insulative sleeve at least partly positioned in the through opening in the board, with the pins fixed to the electrically insulative sleeve, and the electrically insulative sleeve profiled for an interference fit within the through opening.
