Description

Technical Field

[0001] The utility model relates to the technical field of accessories for electronic products, in particular to an interface locking structure for power line plugging. Background Art

[0002] Power cords are wires that transmit electrical current. Current is typically transmitted point-to-point. Power cords can be categorized by their intended use as AC (alternating current) or DC (direct current). AC power cords typically carry higher-voltage alternating current. Due to their higher voltage, these cables require standardized safety certification before they can be officially manufactured.

[0003] An existing Chinese utility model patent, CN2141936Y, is available for reference. It discloses a socket and plug for preventing electrical wires and cables from falling out. The socket primarily consists of a conductive spring, a socket housing, and a front cover. A retaining seat is mounted at the rear end of the front cover, and the conductive spring and retaining seat are integrally cast. The plug primarily consists of a plug housing, a conductive plate, and a front cover, with a conductive plate with a latch secured to the front cover. Advantages of this design include a large contact area between the conductive plate and the spring, allowing for a high current to flow. The conductive plate on the plug has a latch that locks the plug and socket together, preventing them from becoming disengaged. Both the plug and socket feature a power cord locking device at the rear end, preventing the power cord from falling out of the terminal due to external forces.

[0004] The power cords currently on the market generally do not have a locking structure and are only fixed to the socket by the elastic force of the copper sheet inside the socket. They are easy to fall off during use, causing power outages in the equipment. In addition, the existing power cord locking structure is relatively complicated. After the socket is installed, it requires relatively cumbersome operations to disconnect the connection between the power cord and the socket. As a result, it is impossible to quickly disconnect the power cord from the socket in an emergency situation where power outage is required, which reduces the safety of the power cord. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an interface locking structure for power cord plugging, which has the advantages of being able to quickly disconnect the connection between the power cord and the socket and prevent the power cord from falling off the socket, thereby solving the above technical problems.

[0007] Furthermore, the rear end of the pop-up spring is fixedly connected to the socket shell, the interior of the limiting tube contacts the outer side of the pop-up spring, the inner diameter of the pop-up spring is larger than the outer diameter of the positioning tube, and an annular protrusion structure is provided on the outer side of the limiting tube, and the front side of the annular protrusion structure of the limiting tube is a slope structure; the limiting tube can limit the relative position between the connecting tube and the socket shell.

[0008] Furthermore, the power cord is embedded in the center of the positioning tube, and a fixed connection is formed between the power cord and the positioning tube. The length of the positioning tube is smaller than the length of the limiting tube; the positioning tube can limit the relative position between the power cord and the limiting tube.

[0009] Furthermore, the front end outer diameter of the connecting tube is equal to the inner diameter of the limiting tube, the power cord passes through the connecting tube, and a fixed connection is formed between the power cord and the connecting tube; the connecting tube can facilitate fixing the relative position between the power cord and the limiting tube.

[0010] Furthermore, the connecting block is installed on the upper and lower sides of the connecting tube in a symmetrical manner and in a mirror-symmetrical manner with respect to the center of the connecting tube. The left and right ends of the fixed shaft are fixedly connected to the connecting blocks on the left and right sides of the connecting tube respectively; the fixed shaft can allow the buckle to rotate while fixing the relative position between the buckle and the connecting block.

[0011] Furthermore, the upper end of the connecting spring is fixedly connected to the bottom surface of the buckle, and the bottom end of the connecting spring is fixedly connected to the connecting tube, and the buckle is rotationally connected to the connecting block through a fixed shaft; the connecting spring can facilitate the buckle to return to a horizontal state.

[0012] Furthermore, the transmission column is rotationally connected with the movable shaft through the adapter block, and the transmission column is embedded in the slide groove of the rotating block, and the slide groove is an inclined structure; the transmission column can drive the buckle to rotate with the axis of the fixed shaft as the reference when the rotating block rotates.

[0013] The implementation of the present invention will have the following beneficial effects:

[0014] 1. An interface locking structure for power cord plugging in the present embodiment. Due to the setting of the buckle, the buckle is installed on the upper and lower sides of the connecting tube through the fixed shaft and the connecting block in a mirror-symmetrical manner. The front end of the buckle is engaged with the annular structure on the outside of the limiting tube. When performing the plugging operation, it is necessary to rotate the rotating block at the rear end so that the rotating block rotates with the axis of the connecting bearing as the reference. During the rotation, the rotating block will drive the transmission column downward through the slide groove, and the transmission column will drive the rear end of the buckle to move downward, so that the front end of the buckle is lifted upward and the connecting spring is stretched. After the plugging operation is completed and the rotating block is released, the buckle is restored to a horizontal state through the reaction force of the connecting spring on the buckle when stretched, and the buckle is engaged with the annular structure on the outside of the limiting tube, thereby fixing the relative position between the connecting tube and the limiting tube to achieve the effect of fixing the power cord.

[0015] 2. In the embodiment of the present invention, an interface locking structure for plugging in a power cord is provided. Due to the provision of a pop-up spring, during the plugging operation, since the length of the positioning tube is smaller than the length of the limiting tube, when the power cord is inserted into the socket shell, the positioning tube completely enters the interior of the limiting tube, and the front end of the connecting tube squeezes the pop-up spring. After the buckle is engaged with the annular structure on the outer side of the limiting tube, the pop-up spring will always be in a retracted state. When an emergency power outage is required, the front end of the buckle is lifted by rotating the rotating block to cancel the engagement state of the buckle with the annular structure on the outer side of the limiting tube. At this time, the pop-up spring will not be affected by external force, so that the pop-up spring will recover. The reaction force of the pop-up spring on the connecting tube when it recovers enables the power cord to quickly pop out of the socket, thereby quickly disconnecting the connection between the power cord and the socket.

[0025] In one possible implementation,

[0026] Please refer to Figure 1 - Figure 4 An embodiment of the present invention provides an interface locking structure for power cord plugging. In this embodiment, an interface locking structure for power cord plugging includes: a socket shell 1, a limiting tube 11 is fixedly installed on the front side of the socket shell 1, and a pop-up spring 12 is fixedly installed on the front side of the socket shell 1.

[0027] The rear end of the pop-up spring 12 is fixedly connected to the socket housing 1, the inside of the limiting tube 11 contacts the outside of the pop-up spring 12, the inner diameter of the pop-up spring 12 is larger than the outer diameter of the positioning tube 21, and an annular protrusion structure is provided on the outside of the limiting tube 11, and the front side of the annular protrusion structure of the limiting tube 11 is a slope structure.

[0028] Specifically, the socket shell 1 is the same model as the shell of an ordinary socket, which can facilitate fixing the limiting tube 11 to the outside of the socket. The limiting tube 11 can limit the relative position between the connecting tube 22 and the socket shell 1, and the pop-up spring 12 can facilitate popping out the connecting tube 22 from the inside of the limiting tube 11.

[0030] The power line 2 is embedded in the center of the positioning tube 21 , and a fixed connection is formed between the power line 2 and the positioning tube 21 . The length of the positioning tube 21 is shorter than that of the limiting tube 11 .

[0031] The outer diameter of the front end of the connecting tube 22 is equal to the inner diameter of the limiting tube 11 . The power line 2 passes through the connecting tube 22 , and a fixed connection is formed between the power line 2 and the connecting tube 22 .

[0032] The connecting blocks 23 are installed on the upper and lower sides of the connecting pipe 22 symmetrically and mirror-symmetrically with the center of the connecting pipe 22 as the reference. The left and right ends of the fixed shaft 25 are fixedly connected to the connecting blocks 23 on the left and right sides of the connecting pipe 22 respectively.

[0033] The upper end of the connecting spring 26 is fixedly connected to the bottom surface of the buckle 24 , and the bottom end of the connecting spring 26 is fixedly connected to the connecting pipe 22 . The buckle 24 is rotationally connected to the connecting block 23 via the fixed shaft 25 .

[0034] The transmission column 29 is rotatably connected to the movable shaft 27 via the adapter block 28 . The transmission column 29 is embedded in the slide groove 212 of the rotating block 211 . The slide groove 212 is an inclined structure.

[0035] Specifically, the positioning tube 21 can limit the relative position between the power cord 2 and the limiting tube 11, the connecting tube 22 can facilitate fixing the relative position between the power cord 2 and the limiting tube 11, the connecting block 23 can fix the fixed shaft 25, and the buckle 24 can be engaged with the annular structure on the outside of the limiting tube 11 to fix the power cord 2, the fixed shaft 25 can allow the buckle 24 to rotate while fixing the relative position between the buckle 24 and the connecting block 23, the connecting spring 26 can facilitate the buckle 24 to restore the horizontal state, the movable shaft 27 can form a rotational connection between the buckle 24 and the adapter block 28, the transmission column 29 can drive the buckle 24 to rotate with the axis of the fixed shaft 25 as the reference when the rotating block 211 rotates, the connecting bearing 210 can form a rotational connection between the rotating block 211 and the connecting tube 22, and the rotating block 211 can drive the transmission column 29 to move through the slide groove 212.

[0036] Working principle: First, the socket shell 1 needs to be replaced with the shell of an ordinary socket. Since the buckle 24 is installed on the upper and lower sides of the connecting tube 22 through the fixed shaft 25 and the connecting block 23 in a mirror-symmetrical manner, the front end of the buckle 24 is engaged with the annular structure on the outside of the limiting tube 11. When performing the plug-in operation, it is necessary to rotate the rotating block 211 at the rear end so that the rotating block 211 rotates with the axis of the connecting bearing 210 as the reference. During the rotation, the rotating block 211 will drive the transmission column 29 to move downward through the slide groove 212. The transmission column 29 will drive the rear end of the buckle 24 to move downward, so that the front end of the buckle 24 is lifted upward and the connecting spring 26 is stretched. After the plug-in operation is completed and the rotating block 211 is released, the buckle 24 is restored to a horizontal state through the reaction force of the connecting spring 26 on the buckle 24 when stretched, and the buckle 24 is engaged with the annular structure on the outside of the limiting tube 11, thereby fixing the connecting tube 22. The relative position between the positioning tube 21 and the limiting tube 11 can achieve the effect of fixing the power cord 2. During the plugging operation, since the length of the positioning tube 21 is smaller than the length of the limiting tube 11, when the power cord 2 is inserted into the socket shell 1, the positioning tube 21 completely enters the interior of the limiting tube 11, and the front end of the connecting tube 22 will squeeze the pop-up spring 12. After the buckle 24 is engaged with the annular structure on the outer side of the limiting tube 11, the pop-up spring 12 will always be in a retracted state. When an emergency power outage is required, the front end of the buckle 24 is lifted by rotating the rotating block 211, and the engagement state of the buckle 24 with the annular structure on the outer side of the limiting tube 11 is cancelled. At this time, the pop-up spring 12 will not be affected by external force, so that the pop-up spring 12 is restored. The reaction force of the pop-up spring 12 on the connecting tube 22 when the pop-up spring 12 is restored enables the power cord 2 to quickly pop out of the socket, thereby quickly disconnecting the connection between the power cord 2 and the socket.

[0037] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
