## Background
FIELD
The described embodiments relate generally to connectors. More particularly, the present embodiments relate to board-level connectors that can be incorporated into an electronic device.
BACKGROUND
Mobile devices such as laptop and notebook computers, media players, smart phones, tablets, and others have become ubiquitous in the last few years and their popularity shows no sign of abating. Further, there is an increasing desire for compact and light-weight devices to thereby increase portability.
The size of many mobile devices, however, is limited by the size and design of hardware components used in these devices. In many instances, current hardware components are large and bulky and additionally require empty “buffer” zones located around themselves. These unused spaces unnecessarily increases the size of the mobile device.
SUMMARY
The connector system can include an open connector that can be, for example, a connector receptacle, and a connector insert. The open connector can have at least one electrical contact, a bottom, and first and second sides. The first and second sides and the bottom can define a receptacle channel. However, the open connector does not have a top located opposite the bottom. Thus, the receptacle channel is an open channel. The open connector can be connected to a mating surface, which can be a structural component of a mobile device. The mating surface can attach to the first and second sides of the open connector to be located opposite the bottom.
The connector system can include a retainer that can maintain contact between the electrical contacts and the connector insert. The retainer can be located on the connector insert, on the connector receptacle, or on the mating surface. The retainer can fix the position of the connector insert by forcing the connector insert into the mating surface and/or by engaging with a component of the connector insert. The retainer can be a mechanical feature, an adhesive, or the like.
One aspect of the present disclosure relates to a connector receptacle. The connector receptacle includes a body having a base, a first side located at a first end of the base, a second side located at a second end of the base, and an open top above the base and extending from the first side to the second side. In some embodiments, the first and second sides extend above the base of the body and in some embodiments, the first and second sides and the base of the body define a receptacle channel. The connector receptacle can include a plurality of electrical contacts located between the first and second sides and a retainer that prevents movement of a connector insert parallel to the base of the body and that does not prevent movement of the connector insert perpendicular to the base of the body.
In some embodiments, the connector receptacle includes an attachment feature that can secure the connector receptacle to a mounting surface. In some embodiments, the attachment feature can be an adhesive, a magnet, and/or a mechanical fastener. In some embodiments, the plurality of electrical contacts is linearly arranged.
In some embodiments of the connector receptacle, the retainer is a feature of at least one of the electrical contacts. In some embodiments, the retainer can be moved from a first position to a second position. In one such embodiment, a distance separating a portion of the retainer that interacts with the connector insert from the base of the body increases when the retainer is moved from the first position to the second position. In some embodiments, the retainer can apply a force to the connector insert in a direction perpendicular to and away from the base of the body.
One aspect of the present disclosure relates to a connector system. The connector system includes a mounting surface having a planar portion and a connector receptacle connected to the planar portion of the mounting surface. The connector receptacle includes a body having a base, a first side located at a first end of the base, a second side located at a second end of the base, and an open top above the base and extending from the first side to the second side. In some embodiments, the first and second sides extend above the base of the body to connect with the planar portion of the mounting surface. In some embodiments, the planar portion of the mounting surface extends above the base of the body such that the planar portion of the mounting surface, the base, and the first and second sides define a receptacle volume.
In some embodiments, the connector system includes a connector insert partially positioned within the receptacle volume. In some embodiments, the connector system includes a plurality of electrical contacts located between the first and second sides and a retainer that prevents movement of the connector insert parallel to the base of the body and that does not prevent movement of the connector insert perpendicular to the base of the body.
In some embodiments, the retainer can be moved from a first, open position to a second, closed position. In some embodiments, the retainer can compress the connector insert against the mounting surface when the connector insert is in the second, closed position. In some embodiments, the connector insert has a retention feature that interacts with the retainer to prevent movement of the connector insert.
One aspect of the present disclosure relates to a method of assembling an electronic device. The method includes attaching a connector receptacle to a mounting surface. In some embodiments, the connector receptacle includes a body having a base, a first side located at a first end of the base, a second side located at a second end of the base, and an open top above the base and extending from the first side to the second side. In some embodiments, the first and second sides extend above the base of the body to connect with the planar portion of the mounting surface. In some embodiments, the connector receptacle can be connected to the planar portion of the mounting surface such that the planar portion of the mounting surface, the base, and the first and second sides define a receptacle volume. The method can include inserting a portion of a connector insert into the receptacle volume and securing the portion of the connector insert in the receptacle volume.
