Embodiment approach 1

[0077] Embodiment 1 is a connector for establishing an electrical connection with a printed circuit board (PCB) comprising a first set of contact pads and a second set of contact pads arranged in first and second rows on the same surface of the PCB. A set of contact pads, the connector comprising: a first set of elongated contacts having contact surfaces forming a first row of contact surfaces configured to electrically connect and disconnect the first set of contact pads of a PCB connection; a second set of elongated contacts having contact surfaces forming a second row of contact surfaces configured to electrically connect and disconnect electrically with a second set of contact pads of the PCB; and a contact block, the The contact block supports the first set of contacts and the second set of contacts and causes the contact surface to wipe the first set of contact pads and the second set of contact pads when electrically connecting and disconnecting the first set of contact ...

Embodiment approach 2

[0078] Embodiment 2 is the connector of embodiment 1, wherein: each of the contacts includes a trailing surface spaced from the contact surface; and the contact block is configured to receive a plurality of conductive pins each having an engagement surface, and to enable The trailing surfaces of the first set of contacts and the second set of contacts wipe against the engagement surface.

Embodiment approach 3

[0079] Embodiment 3 is the connector of embodiment 1, wherein: the contacts of the first set of contacts are spaced apart from each other and aligned along a first plane perpendicular to the contact block; the contacts of the second set of contacts are spaced apart from each other and aligned aligned along a second plane perpendicular to the contact block; and the first plane parallel to the second plane.

Abstract

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.

Description

technical field [0001] This application generally relates to electrical connectors and related methods. Background technique [0002] Electrical connectors have been developed for a variety of applications. For example, conventional test equipment utilizes electrical connectors and arrays of test probes to connect circuit board electronics and electronic devices under test. Such test equipment has been used to test electronic devices from various industries such as computing, automotive and telecommunications. While such test equipment is generally effective and has been used in these industries for many years, the density of electrical connectors utilized by such test equipment is limited. Therefore, in some cases it cannot be used to test devices with a larger number of contact pads or with some types of arrays of contact pads. Additionally, electrical connectors used with such test equipment have a heavily automated assembly process of soldering the connector to the pr...
