Prior Art further proposes a socket contact that has the potential to do both wiping and a contact position. It is evident that the related applications wherein referenced above falls short of describing, proposing or presenting an electrical connector with a dual inline design, and which like others describes herein is capable of wiping and performing diverse contact functions on a detachable, inserted pin. The invention proposed herein differs from other related applications in the use of dual-in-line contact and the use of a detachable gas tight contact interactive circuit board-connector mechanism. The Background of the Invention (including prior art) The current invention refers to electrical connectors. Specifically, it proposes an electrical connector comprising of a dual-in-line mechanism and a printed circuit board. It comprises of a unique receptacle that consist of a plurality of female contacts designed in a dual-inline fashion. Similar to other prior art discussed herein, it is also capable of performing wipe and contact, especially for male pin contacts that have been customized to lock with the receptacle. Besides, the connector is designed with contact points adapted for electrical communication through the connector’s circuit board. These detachable contact points are fixed onto the printed circuit using soldered pads. The invention is unique in different ways, and has several merits over other existing electrical connectors. One unique component in the connector is the detachable gas tight contact that is placed between the receptacle and the printed circuit. The circuit board has few through holes, hence eases of replacement and reduced cost. Further, it is dissimilar to other existing applications as it is highly flexible and hence eliminating the need for whole masking as with other similar connectors. As a result, there are decreased assembly costs, tooling costs as well as reduced maintenance costs. The invention is highly flexible and is highly compliant with other electrical conventional applications. Its compliant pin can be fixed onto a single or multiple circuit boards. It is best suited for electrical applications where the connectors are to be fixed on either side of the double-sided circuit board. One side of the circuit board will consist of conventional pin connectors that are compliant for cost savings. For purposes of minimizing assembly costs, one of the printed sides will have a solder-free connector as it is associated with reduced installation costs. The current invention is unique as it is detachable, highly flexible and makes use of the printed circuit board. It is best for applications where flexibility and cost effectiveness is considered critical. The herein proposed electrical connector comprises of different other mechanical advantages over similar pre-existing electrical connectors. One key advantage of the connector over other existing connectors is its enhanced rise times and most importantly, it’s reduced drive capacitance that surpasses that of conventional, pin connectors. The current invention completely eliminates the RF radiation that is associated with conventional pin connectors. It also has a distinct mechanical feature that gives it the capacity to withstand countless number of pin insertions and withdrawals unlike other similar pin compliant connectors discussed herein. This unique design reduces both the installation and maintenance costs that are associated with similar conventional connectors. The current invention proposes a novel connector that utilizes a dual-inline contact mechanism to enable it perform contact function. In addition, it uses a detachable contact principle and a printed circuit board. A Brief Summary of the Invention The current invention relates to an electrical connector, and comprises of a receptacle holder and plurality conductive channels that extend to the entire body of the connector. In all of the communication channels, a dual-in-line contact component is predisposed. Each of the contact components consists of two convex parts that are internally facing. Additionally, it has a contact leg that runs through the bottom wall and goes all the way to the opposing direction. The connector’s contacts are customized to fit into male pin contacts. This is possible through pin insertions in the receptacle’s communication channels. The two convex components of the contacts offers contact areas for inserted pins and perform wiping functions. The receptacle is designed in such a way as to fit onto the printed circuit through its leg contacts, affixed onto a conductive strip. In the invention, the contacts are connected to the board through holes. The contacts are made of soft metals so as to withstand high contact pressures when the contacts are conjoined. Consequently, the metal is set such that the joint prohibits gases from entering into the contact environment. The invention comprises of different aspects. These include a provision for electrical connector adaptability for electrical mating with a corresponding plug component consisting of a plurality of male. It is also adapted for mounting upon printed circuitry. The connector herein refereed to consist of a receptor casing that comprises of front and rear walls. Besides, it also has a pair of side and end walls. Furthermore, it consists of a both top and bottom walls, and a pair of spaced passageways that runs through the connector casing. There is an allowance for contact components to fit within the body, and has custom made communication channels while each contact component comprises of a gas tight contact. The second facet of the invention is that it comprises of an electrical connector that is designed for paired functional mating with a similar plug component.

The connector is fabricated and forms part of the molding insulation comprising of polyester material. The connectors’ body has a front, rear and end walls. The front wall is indicated as 12, the rear wall as 14, while the two end walls are represented as 16. Additionally, the drawing shows top and bottom wall labeled as 18 and 20. Communication channels or passageways are referenced as 22, and extends all the way through the casing via the top wall, and goes through the bottom part of the body. This illustrated in figure 3. A metallic strip labeled as 23, is fabricated of steel and covers the upper part of the connector. As shown in figure 3, the communication openings are designed in a two row format thereby creating a passageway. These rows are depicted in Figure 2. Figure 3 shows two rows that comprise the passageway that runs through the central wall of the connector body. The central wall is labeled as 24, and forms part of the receptacle body. The connector also consists of a protruding shoulder labeled as 26 which has two sides labeled as 28 and 29. These two sides are made in such a way so as to project into the passageways. As depicted in Figure 3, a contact component 30 is shown on either side of the passageways, labeled as 22. Additionally, contact components, 30, which have a dual-inline construction, are made from a piece of conductive material. These components can be described as simply a piece of flat shank, 32. One end of the flat shank terminates in one of the convexes while the other one terminates in a leg mounted onto the circuit board. The two convexes are labeled as 34 and 42 respectively. The constructions of the convexes are illustrated in figures 3 and 4. The end points for both convexes are disposed especially on the pin mounted side, 43. Figure 3 further shows component members, 30, as they look when they are held in passageways that comprises the connector’s receptacle. This is evident on the pin side labeled as 43 whereas the convex parts 34 and 42 all face the interior part, 46 of either the front or rear part of the receptacle. The contact components are firmly held in position using projection 48 that is one the contact components while the pin side actually faces the shoulder, labeled as 26 and forms part of the central wall. The passageway 22 allows the projection of the circuit board fixed leg 36. This fixed on the bottom wall, 20 which is part of the receptacle that extends all the way to the rear walls.
