Multiple row connector with zero insertion force
A connector for establishing electrical connections with a PCB comprises first and second sets of contact pads arranged in first and second rows on a same surface of the PCB. The connector includes a first set of elongated contacts, a second set of elongated contacts, and a contact block. The first set of contacts have contact surfaces that form a first row of contact surfaces configured to make and break electrical connectivity with the first set of contact pads of the PCB. The second set of contacts have contact surfaces that form a second row of contact surfaces configured to make and break electrical connectivity with the second set of contact pads of the PCB. The contact block supports the first and second sets of contacts and causes the contact surfaces to wipe against the first and second sets of contact pads when making and breaking electrical connectivity therewith.
1. A connector for establishing electrical connections with a printed circuit board (PCB) comprising first and second sets of contact pads arranged in first and second rows on a same surface of the PCB, the connector comprising:
a first set of elongated contacts having contact surfaces forming a first row of contact surfaces configured to make and break electrical connectivity with the first set of contact pads of the PCB;
a second set of elongated contacts having contact surfaces forming a second row of contact surfaces configured to make and break electrical connectivity with the second set of contact pads of the PCB;
a contact block supporting the first and second sets of contacts and to cause the contact surfaces to wipe against the first and second sets of contact pads when making and breaking electrical connectivity therewith; and
a contact organizer disposed adjacent the first and second sets of contacts, the contact organizer comprising first and second faces each having engagement surfaces configured to direct the first and second rows of contact surfaces into and out of engagement with the first and second sets of contact pads with movement of the contact block.
2. The connector of claim 1 , wherein:
each of the contacts comprises a tail surface spaced apart from the contact surface; and
the contact block is configured to receive a plurality of electrically conductive pins each having an engagement surface, and to cause the tail surfaces of the first and second sets of contacts to wipe against the engagement surfaces.
3. The connector of claim 1 , wherein:
contacts of the first set of contacts are spaced apart from one another and aligned along a first plane normal to the contact block;
contacts of the second set of contacts are spaced apart from one another and aligned along a second plane normal to the contact block; and
the first plane is parallel to the second plane.
4. The connector of claim 1 , further comprising:
a base configured to receive a plurality of electrically conductive pins that contact tail surfaces of the first and second sets of contacts; and
a cover configured to receive a portion of the PCB and couple the contact organizer to the base.
5. The connector of claim 4 , wherein the contact organizer latches to the cover and the cover is connected to the base by a snap-fit.
6. The connector of claim 4 , wherein the cover comprises opposing first and second cover portions, each cover portion coupling the contact organizer to the base by pivoting over the contact organizer.
7. The connector of claim 4 , wherein one or more of the cover, the contact organizer, the first set of elongated contacts, the second set of elongated contacts and the contact block comprise separable modules that are disposed along the base.
8. The connector of claim 1 , wherein the contact organizer is adapted to receive a portion of the PCB and the engagement surfaces are configured to space the first and second sets of contact surfaces apart from the first and second sets of contact pads by a variable distance with movement of the contact block relative to the contact organizer.
9. The connector of claim 8 , wherein the engagement surfaces are configured to space the first and second set of contact surfaces from the first and second set of contact pads such that electrical connectivity is not established when the contact block is disposed in a first position.
10. The connector of claim 8 , wherein the engagement surfaces are configured to allow the first and second set of contact surfaces to engage the first and second set of contact pads such that electrical connectivity is made when the contact block is disposed in a second position.
11. The connector of claim 8 , wherein the engagement surfaces comprise first and second sloped surfaces configured to slidably engage the first and second sets of contacts with movement of the contact block.
12. The connector of claim 1 , wherein the PCB comprises third and fourth sets of contact pads arranged third and fourth rows on a second surface of the PCB, the second surface opposing the first surface, the connector further comprising:
a third set of elongated contacts having first contact surfaces forming a third row of contact surfaces configured to make and break electrical connectivity with the third set of contact pads of the PCB;
a fourth set of elongated contacts having first contact surfaces forming a fourth row of contact surfaces configured to make and break electrical connectivity with the fourth set of contact pads of the PCB; and
the contact block having a second section supporting the third and fourth sets of contacts and to cause the contact surfaces to wipe against the third and fourth sets of contact pads when making and breaking electrical connectivity therewith.
13. The connector of claim 12 , wherein the first and second sets of contacts are arranged in columns and the third and fourth sets of contacts are arranged in columns.
14. The connector of claim 1 , wherein the contact surfaces have a toroid shape.
