Detailed ways

1 and 2 illustrate connector embodiments and components. Referring to Figure 2, the connector consists of a front cover "700", a movable sleeve "750", an elastic member "752", a conductive base "850" and a bottom cover "800"; it may also include a plug shutter "900" , Interchangeable protective case "751", a light guide "950", a safety lock "753".

In Figures 2 and 3, the function of movable sleeve "750" is to prevent conductive arm "852" from being positioned in a position where arcing can occur. This function is achieved in "800" by the spike feature "757" and the grooves "801" and "802".

Front cover "700", movable sleeves "750" and "850" are rotated together by screw rod "701".

The upward movement of "750" is achieved by spring "752", which acts on "754" and "853" (in Fig. 11).

Figure 6 shows the connector in the "OFF" position. In this position, "757" engages with groove "801". In this position, "850" is prevented from rotating.

In order to operate the connector, a downward force is required on movable sleeve "750" to allow rotation of "850", as shown in Figure 10.

Figure 9 illustrates the device with the connector in a non-operational mode. Figures 7 and 12 illustrate arc protection locations. The groove "802" has a gradient that forces the "757" to slide in, while the "803" prevents the adapter from accidentally being powered on. Figure 8 shows the connector in the "ON" position.

Compared to the previous conductor embodiment (Figure 15), since the contacts "902" (Figure 16) are not constrained, the arc must be diverted to "901" to ensure the integrity of the contact surface. In addition, "901" must be made of arc-proof engineering materials, such as silver cadmium oxide. From an ergonomic standpoint, the connector shown in Figure 13 exhibits an easy disconnect due to the lack of a mechanical latch. This causes the connector to lose power frequently and unexpectedly. In contrast, grooves "801", "802" and "757" mechanically prevent this problem.

Figure 11 shows the components that make up the "850". Conductors "854", "855", "856" are manufactured from one conductor. This improves conductivity because the conductor is in direct contact with the plug.

In contrast, Figures 15 and 16 show the prior art where conductor "907" is riveted "904" where another conductive jaw "908" is secured to "904". This leads to significant contact resistance and thus significant energy loss.

Additionally, the single conductor "854" simplifies the manufacturing process by eliminating the need for floating rivets "903".

Another improved part is "861", "862" and "863". A preferred embodiment of the conductive sheet "861" is shown in Figure 18. It consists of a simply folded conductive material with features "864" and contacts "865" as slide-in surfaces. Contact point "865" is in contact with conductor "863" and is held in place by insulator "862". "862" has captured the feature latch in "863". The contact pressure between "861" and track conductor "1000" is exerted by elastic material "866". Therefore, insulator "862" also helps prevent "866" by providing an alternate current path, preventing the material from heating up and losing its elastic properties.

In the prior art in Fig. 17, the conductive arm includes a fixed base "913", a spring "911", a hollow barrel "910", a gradient surface "912" and a dome-shaped conductive member "909". The hollow barrel "910" is expensive to manufacture because of the need for small and precise dimensions. In terms of assembly, "913" must be fixed on "915", while "911" and "909" must be put into the bucket "910", which requires an additional assembly process. In terms of performance, the contact resistance is high because of many contact surfaces, such as "913", surface "916" and inner barrel "910", "909" and inner barrel. Therefore, current parts must be silver-plated to help alleviate high contact resistance.

Compared with the prior art shown in Fig. 17, the conductive arm shown in Fig. 11 is simple to manufacture, simple to assemble, and stable in electrical performance. Embodiments of the present invention are improvements in manufacture, fit and performance.

Electrical connectors can also include a security lock "753" to prevent theft of the connector and also as an anti-closing feature. "753" consists of a screw "753" and a screw "758". "758" can be operated through hole "756". When the 758 is rotated outward, it prevents the movable sleeve 750 from being pressed down, accessing the electrical connector, and cannot be removed.
