Mating connector for a micro USB connector
View Patent ↗A mating connector construction that achieves a slimmer and smaller profile when mating with a conventional USB connector. A slimmer and smaller profile provides substantial advantages and additional uses of a USB connection, for example, with transmitting signals between a watch casing and a watchstrap, as but one example thereof. In a preferred embodiment, the USB connector is a micro USB connector.
1. A mating connector that mates with a universal serial bus (USB) connector, wherein the USB connector comprises a receptacle shell, a plurality of contact pins mounted on a support plate, wherein each of the contact pins has an electrical contact surface oriented in a respective first plane, wherein the support plate and the plurality of contact pins are positioned within the receptacle shell, and wherein the receptacle shell has an opening for receiving the mating connector; wherein the mating connector comprises:
a first end of a flexible printed circuit board (PCB), wherein the PCB has a plurality of electrically conductive tracks terminating at respective first ends, all of which are proximate the first end of the PCB;
a plurality of contact pads, each respectively electrically coupled to a respective conductive track, wherein each of the contact pads has a surface lying in a plane at least essentially orthogonal to the respective first plane of each of the electrical contact surfaces of the respective contact pin to which it is electrically coupleable when electrically coupled thereto;
a plurality of spring connectors, each having a respective first end and a second end, the respective first end of each being electrically coupled to a respective contact pad and the respective second end of each being electrically coupleable to a respective electrical contact surface of a contact pin; and
a housing, shaped to be insertable within the opening of the USB connector, for enclosing (i) the first end of the PCB, (ii) the respective first ends of the conductive tracks, (iii) the plurality of contact pads and (iv) at least the respective first ends of the spring connectors.
2. The mating connector as claimed in claim 1 , wherein the spring connectors are generally “L-shaped” spring connectors.
3. The mating connector as claimed in claim 1 , wherein the USB connector is a micro USB connector.
4. An assembly comprising:
a universal serial bus (USE) connector, wherein the USB connector comprises:
a receptacle shell,
a plurality of contact pins mounted on a support plate, wherein each of the contact pins has an electrical contact surface oriented in a first plane, wherein the support plate and the plurality of contact pins are positioned within the receptacle shell, and wherein the receptacle shell has an opening for receiving a mating connector;
a mating connector comprising:
a first end of a flexible printed circuit board (PCB), wherein the PCB has a plurality of electrically conductive tracks terminating at respective first ends, all of which are proximate the first end of the PCB;
a plurality of contact pads, each respectively electrically coupled to a respective conductive track, wherein each of the contact pads has a surface lying in a plane orthogonal to the first plane of each of the electrical contact surface of the respective contact pin to which it is electrically coupleable;
a plurality of spring connectors, each having a respective first end and a second end, the respective first end of each being electrically coupled to a respective contact pad and the respective second end of each being electrically coupled to a respective contact surface of a contact pin; and
a housing, shaped to be insertable within the opening of the USB connector, for enclosing (i) the first end of the PCB, (ii) the respective first ends of the conductive tracks, (iii) the plurality of contact pads and (iv) at least the respective first ends of the spring connectors.
5. The assembly as claimed in claim 4 , wherein the USB connector is a micro USE connector.
