Definitions
- the invention relates to electrical plug containing a mechanical system allowing the plug to be more easily removed from an electrical socket.
- electrical plugs there are often difficulties to remove the plug from the electrical socket. These difficulties arise from excessive pressure of contact elements embedded in the electrical socket on the plug's pins. High pressure of the contacting components, preferred because of the conduction of electric current, makes difficult to remove the plug from the electrical socket and therefore pull out of the electrical socket from the wall may occur.
- Patent description DE 19708800 Al describes an electrical plug having a body, in which there are embedded contact pins connected with electric conductors. In the middle of the body there is a through-hole, in which there is a pushpin with a length greater than the length of the hole, and the neck of said body is tapered allowing for fingers hold. Pulling the plug from an electrical socket requires grasping the body with fingers and pressing on an ejector, which by pushing on the inner surface of the socket causes the plug to eject.
- An electrical plug known from patent description DE 19513170 like the one presented above, is equipped with an ejector extending throughout the through-hole in the body. This ejector is equipped on the one end with a shaped button and from the electrical socket side with cross foot.
- the problem to solve is to provide a plug constructed in a way that it can be easily removed from the electrical socket without the of fear loosening or even detachment of the socket from the wall.
- the plug should be ergonomic, is, easy to grasp and remove using only one hand.
- the plug should have dimensions no larger than a standard plug, which allows plugging-in of several plugs next to each other, to the sockets arranged in standardized distances on the power strip.
- Standard plug has a housing, in which there are arranged and protrude from the front surface contact pins. On its side, the housing has a lug, through which the power cord is run and connected to the contact pins. On the sidewall, near the rear surface the housing has an omnidirectional protrusion or at least two protrusions. At the rear, the housing incorporates a bottomed recess. Inside of the housing there is at least one through channel, that extends from the bottom of the recess to the front surface and it is parallel to the longitudinal axis of the contact pins. In the channel there is an inserted stem terminated with a button entering into the recess, wherein the steam and the button assemble an ejector.
- the plug according to the invention is characterized in that, the through channel on the part of its length, not less than 5 mm, from the front side is widened, at least one side by an amount "m", and the stem has on its side surface, at least one hook-shaped latch entering the widening of the channel m, wherein said hook-shaped latch is formed by the inclined surface, the surface area of the longitudinal slot and the surface of the cross indentation.
- Material used for the steam and consistent with it hook-shaped latch has elastic properties.
- the height of the hook-shaped latch in an unloaded position is equal to or lesser than the amount "m" of the widening of the channel.
- hook-shaped latch due to the presence on its front of the inclined surface and from the bottom of the longitudinal slot, is subject to bending during the insertion of the stem into the housing channel.
- the cross indentation is situated on the rear side of the hook-shaped latch, when viewed from the front side of the steam.
- This cross indentation forms a resistance surface.
- the height "w" of the hook-shaped latch in an unloaded position, is equal to or lesser than the amount "m” of widening of the channel.
- hook-shaped latch has a reinforced structure. It's inclined surface begins from a side surface of the steam and, in the normal position - not pressed, rises until reaching the height "w". It's cross-section, largest at the base, which is a condition of increased strength, gently decreases over the entire length and the resistance surface is formed by it's entire rear surface.
- the steam in a different embodiment, in the cross-sectional has a shape resembling the letter T and has a high strength despite being weakened by a cut of the longitudinal slot and the cross indentation. Moreover, such a shape of the ejector steam is preferable because of the arrangement of the channels and the other parts of the plug, which is clearly visible in the front view of the plug.
- the dimensional sizes of the channel cross-section together with its widening "m" and the dimensional sizes of the cross-sectional of the stem together with the hook-shaped latch are mutually selected to form a sliding fit, which facilitates the relative sliding motion of these elements.
- a compression spring of which one end is mounted on the pin located in the middle of the inner sidewall of the button and the other end is based on the front surface of the bore in the wall of the bottom.
- This spring keeps the ejector in the maximum retracted position "to the back,” at which the front surfaces of the stems of the ejector are fully retracted.
- the compression spring is applied on said stem, and spring's one end is based the inner surface of the button and the other end is based on the front surface of the bore in the wall of the bottom.
- the plug according to the invention has a compact and simple to implement design.
- a channel in which there is widening by amount m and the stem of the ejector with hook-shaped latches.
- shaped elements do not increase the cost of construction of the plug, but fundamentally facilitate their mutual assembly, which simply consists of inserting the stem or the steams of the ejector into the channel in the housing in the plug. In case of damage to the ejector, it shall be discarded, and the new, undamaged ejector inserted in the channel.
- An additional element used in the ejector is a spring, which the installation involves positioning of the spring on the steam on the inner wall of the button and pressing the stems of the ejector into the channels in the housing.
- the spring slides over the stem, and in this position steam of the ejector is pressed into the channel in the plug's housing.
- the ejector button is partly housed in the cavity of the housing and as the movable element is shielded by this housing against possible damage and unwanted pressing.
- On the sidewall of the housing there is an omnidirectional protrusion or at least two protrusions.
- the omnidirectional protrusion implemented in high power plugs increases their ergonomics, as the plug to be removed can be grasped with the fingers, by sliding them from any position and at any angle.
- Universal plugs and low power plugs have two protrusions located on opposite sides, which also makes them comfortable in use. After inserting fingers under the omnidirectional protrusion or side protrusion on the connector housing, and pressing thumb on the button causes the free eject of the plug from the wall socket. During removing of the plug, the electrical socket is not affected.

- Figure 17 shows the ejector of this plug in a perspective view
- Fig. 18 shows the ejector in a side view in the direction of arrow C indicated in Figure 17.
- Example of the invention 1 - a universal medium power plug.
- a medium power plug has a housing 1, in which there are arranged and protrude from its front surface 2 contact pins 3.
- the housing 1 On its side, the housing 1 has a lug 4 through which a power cord 5 is run and connected to the contact pins 3.
- the housing 1 On the sidewall, near a rear surface 6 the housing 1 has two symmetrically arranged protrusions 8 and inside the housing 1 there are two through channels 9, in which stems 10 of an ejector 11 are inserted.
- the housing 1 comprises a recess 12 with a bottom 13 located in the rear side of said housing. Each of the through channels 9 passes from the bottom 13 to the front surface 2 and its parallel to the longitudinal axis of the contact pins 3.
- the ejector 11 is formed from two stems 10 terminated with integrated button 16 entering the recess 12.
- the stem 10 has on its side surface a hook-shaped latch 17 entering, in the assembled plug, into the widening "ni" of the channel 9.
- the hook- shaped latch 17 is formed by an inclined surface 18, the surface of a longitudinal slot 19 and a surface of a cross indentation 20.
- the longitudinal slot 19 allows for bending of the hook-shaped latch 17 during insertion of the stems 10 of the ejector 11 into the through channels 9.
- a compression spring 26 of which one end is mounted on a pin 25 located in the middle of the inner sidewall of the button 16 and the other end is based on the front surface of a bore 27 in the wall of the bottom 13. It is possible to construct a plug without the compression spring 26. But then the ejector 11 can occupy any position in the channel 9 and then the steams 10 can extend from the front side 2 of the plug that is not inserted into the electrical socket.
- Example of the invention 2 - a high power plug Shown in Fig. 5, Fig. 6, and Fig. 7 a high power plug is different from the universal medium power, as described in detail in the example 1 , by implementation of omnidirectional protrusion 8 (instead of the two protrusions 7).
- the protrusion 8 also acts as a shield for a button 16 and completely shields the button 16.
- a low power plug has a flattened housing 1 , in which there are arranged and protrude from its front surface 2 contact pins 3.

- the stem 21 has on its side surface, symmetrically on both sides, hook-shaped latches 17 entering, in the assembled plug, into the widening m of the central channel 14.
- Each of the hook- shaped latches 17 is formed by an inclined surface 22, the surface of a longitudinal slot 23 and a surface of a cross indentation 24.
- the longitudinal slots 23 allow for bending of the both hook-shaped latches 17 during insertion of the stem 21 of the ejector 15 into the through channel 14.
- a compression spring 26 which is mounted on the steam 21, the spring's one end is based on the inner surface of the sidewall of the button 16 and the other end is based on the front surface of a bore 27 in the wall of the bottom 13.
- this plug can also be used without the compression spring.
- Example 4 variant embodiment of the plug.
