Title of Invention: A PRINTED CIRCUIT BOARD CONNECTOR
[ 1 ] FIELD OF INVENTION
[2] The present invention relates to a device for connecting two printed circuit boards in series.
[3] BACKGROUND OF THE INVENTION
[4] Printed circuit board is considered one of the most fundamental components in an electronic device. Some electronic devices have more than one printed circuit board to operate, thus requires those printed circuit boards to be connected. One of the examples of the connector isUS 7,497,697, where it relates toa connector includes a socket in which first contacts are provided parallel to an opening edge portion and a plug which has a flat shape capable of fitting in the opening edge portion of the socket. The plug includes second contacts provided parallel to positions corresponding to the first contacts in the plug. A guide portion is provided in either the opening edge portion of the socket or an outer peripheral edge portion of the plug. However, it is found that one of the obvious drawbacks of this prior art is it does not provide waterproof connection.
[5] The common problem to interface the contact between two separate printed circuit boards assembly while having waterproof capability are: lack of modularity in design due to many uniqueness of features in order to ensure contact is successful between different boards, too many degree of customization therefore increase in price and decrease utilization flexibility, many constraint or attributes to consider like gap allowance, force requirement to ensure sealing in order to meet challenging waterproof design, not the simplest integration of two connecting devices and also installation and un-installation for maintenance, and the usage of standard off-the-shelf part is impracticable due to many constraints like no. of contacts, size and geometry.
[6] Therefore it is a need for an invention which provides solutions to above drawbacks.

aprinted circuit board connector comprising: a metal connector (100) having a dimple (100a) on each end to connect two printed circuit boards (200); characterized in that the metal connector (100) is housed by an elastomeric holder (300) providing waterproof solderless-but-firmer hold of the connection between the two printed circuit boards (200). The elastomeric holder (300) further comprising: an enclosure (300a) having a slot (300b) through the enclosure (300a), wherein the slot (300b) receives the printed circuit board (200) from each end; the metal connector (100) is fixed inside the enclosure (300a); a retainer wall (300c) to separate the two printed circuit boards (200) from directly joining in series; inner bump feature (300d) inside the enclosure (300a) to force the printed circuit board to stay firm inside; outer bump feature (300e) on the body of the enclosure (300a); andchamfers (300f) as a guide feature for ease of assembly of the printed circuit boards (200).
[9] The elastomeric holder (300) is used to prevent water intrusion onto the metal
connector (100) and the printed circuit boards (200) therefore preventing short-circuit from happening and also protecting the component on the board from oxidization. The inner bump feature (300d) inside the enclosure (300a) provides sealing engagement between the enclosure (300a) and the printed circuit boards (200). Meanwhile, sealing engagement of the enclosure (300a) with the surrounding wall is provided by the outer bump feature (300e) on the body. The slot on the elastomeric enclosure is having chamfers (300f) as a guide feature for ease of assembly of the printed circuit boards (200).
[10] The metal connector (100) is used to make a direct contact with the printed circuit boards (200) contact that requires no soldering. It is designed and shaped for the simplest manufacturing process without complicated sheet metal forming involved. The connector (100) is independent of any number of contact point required, geometry, planarity and distance in between. The dimple (100a) on each of the contact surface is to ensure positive physical touch and continuous electrical connectivity.

This provision is illustrated in Figure 1, Figure 2, Figure 3, and Figure 4. The elastomeric holder (300) further comprising: an enclosure (300a) having a slot (300b) through the enclosure (300a), wherein the slot (300b) receives the printed circuit board (200) from each end; the metal connector (100) is fixed inside the enclosure (300a); a retainer wall (300c) to separate the two printed circuit boards (200) from directly joining in series; inner bump feature (300d) inside the enclosure (300a) to force the printed circuit board to stay firm inside; outer bump feature (300e) on the body of the enclosure (300a); and chamfers (3000 as a guide feature for ease of assembly of the printed circuit boards (200). The location of chamfers (300f) is illustrated in Figure 5.
[19] The elastomenc holder (300), having the elastomer compression properties, continuously inducing positive compression force on the printed circuit board (200) whereby it prevents water intrusion onto contacts and the printed circuit board (200) therefore preventing short-circuit from happening and also protecting the component on the board from oxidization as every component or feature of the elastomeric holder would fill any gap during assembly due to its elastic character. The natural rubber properties of the elastomer holder (300) also ensures the enclosure (300a) slot provides secure and firm sealing engagement between the enclosure (300a) and the printed circuit boards (200). Properly designed, the elastomeric enclosures (300a) continuously grip and seal the printed circuit boards (200) which its grip is firm as if the printed circuit boards (200) are fixed with soldering connections. Having the elastic character, the elastomeric holder (300) can be shaped with a guide feature on shoulders to guide and ease of assembly into a host/carrier.
[20] The metal connector (100) is used to make a direct contact with the printed circuit board contact that requires no soldering. It is designed and shaped for the simplest manufacturing process with no complicated sheet metal forming involved. The metal connector (100) has at least a dimple (100a) at the end to ensure positive physical contact and electrical connectivity. The metal connector (100) having optimally designed and shaped for the simplest manufacturing process for integrating with the elastomeric enclosure, is independent of any number of contact point required, geometry, planarity and distance in between.
[21] The slot (300b) on the elastomeric holder (300) is having chamfers (300f) as a guide feature for ease of assembly of the printed circuit board (200) while the retainer wall (300c)is deliberately designed to act as stopper to prevent the PCB from hitting each other when fully inserted.
[22] The present invention features straight sheet metal with no complicated forming as a means to connect between two boards. This can eventually benefit the host as the host design can be miniaturized and meeting space constraint requirement.
[23] Although the invention has been described with reference to particular embodiment, it is to be understood that the embodiment is merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiment that other arrangements may be devised without departing from the scope of the present invention as defined by the appended claims.
