Anti-drop socket

Abstract

The present invention discloses an anti-dropout socket, which relates to the technical field of electrical sockets. The socket is formed by a top cover and a bottom cover, and is further provided with an anti-dropout mechanism. The anti-dropout mechanism includes: a partition fixed between the top cover and the bottom cover, an elastic support seat provided between the partition and the top cover, and an anti-dropout piece provided on a seesaw mechanism. The top cover, the anti-dropout piece, the elastic support seat, the partition, and the bottom cover are all provided with first sockets corresponding to each other. The anti-dropout piece applies or releases a tight locking force to a first pin mainly by a left arm pressing a left spring downward or releasing the pressure on the spring, causing the anti-dropout piece to tilt or reduce its tilt to prevent or release the first pin. After long-term use, even if the elastic force of the left spring weakens, the right spring is sufficient to support the entire elastic support seat to return to its original position. After long-term use, the user experience of the anti-dropout socket may only be that the button is relatively easy to press, but the anti-dropout socket can still apply a tight locking force to the first pin. The anti-dropout socket can also ensure that the first socket of the anti-dropout piece is properly positioned.

Description

Technical Field

[0001] The present invention relates to the technical field of electric sockets, in particular to an anti-dropping socket. Background Art

[0002] If the socket is used in an environment subject to external forces such as vibration and pulling, the plug on the socket may gradually loosen and eventually fall off, causing electrical equipment to stop working or damage. Therefore, the manufacturer provides anti-drop sockets to solve this problem.

[0003] Referring to the Chinese patent application publication number CN104733924A anti-electric shock, dust-proof and anti-dropout socket, due to the limited space of the national standard socket, one of its core technical points is how to loosen or lock one of the anti-dropout pieces (limiting parts) to achieve normal insertion and anti-dropout; the second core technical point is how to make the anti-dropout piece (limiting part) in the right position.

[0004] Chinese patent CN104733924A is an anti-electric shock, dust-proof and anti-dropout socket. Its specification discloses that "when it is necessary to insert the plug of an electrical appliance, the electrical appliance plug is directly inserted into the socket 3, and the metal anti-dropout piece 43 changes from the original tilted state pushed up by the key spring 42 to the flush state under the pressure of the plug insertion. When the electrical appliance plug is fully inserted, the key spring 42 pushes the metal anti-dropout piece 43 up and tilts it under the action of elastic force, and the plug is locked; when it is necessary to unplug the electrical appliance plug, press the key 41 to make the metal anti-dropout piece 43 change from the original tilted state pushed up by the key spring 42 to the flush state. At this time, the plug is released and can be easily unplugged. That is, the above technical solution is to use the elastic force of the key spring to act on the metal anti-dropout piece The sheet makes one end of the metal anti-slip sheet tilt relative to the placement slot; when the button is triggered by external force, it further drives the key spring connected to the button to make the metal anti-slip sheet parallel. The first fixing member 44 is fixedly installed on the bottom cover 2, and the first fixing member 44 is provided with a placement slot 441. The metal anti-slip sheet 43 is provided on the placement slot 441. The metal anti-slip sheet 43 is provided with a first through hole 431 corresponding to the socket 3. One end of the button 41 is provided on the first fixing member 44 and is connected to the key spring 42, and the other end is exposed outside the cover 1. One end of the key spring 42 is fixed to the inner wall of the bottom cover 2, and the other end is against one side of the metal anti-slip sheet 43. "Its main problems are as follows:

[0005] 1). Its specification only states that "one end of the button 41 is provided on the first fixing member 44 and is connected to the button spring 42, one end of the button spring 42 is fixed to the inner wall of the bottom cover 2, and the other end is against one side of the metal anti-drop sheet 43". Figure 1-3The following is a deduction about how to return the metal anti-slip plate of an anti-electric shock, dust-proof and anti-slip socket to a flush state: First, the fixing part is fixed and immovable. In order for the metal anti-slip plate to return to a flush state from its original tilted state pushed up by the key spring, it is necessary to operate the key to cause the key spring to pull back a certain distance to return the metal anti-slip plate to a flush state. This requires the designer to have absolute control over the elastic force of the spring in order to accurately design the strength of the pull-back spring and the required pull-back distance. When the spring's elasticity weakens after long-term use, if the original design is used to apply the same spring pull-back distance, errors will often occur, resulting in the inability to return the metal anti-slip plate to a flush state, resulting in improper insertion or the metal anti-slip plate not being able to prevent slipping tightly. Moreover, even if the pin can be smoothly plugged into the socket after the elasticity weakens, the key spring may not be able to push the metal anti-slip plate back to its original tilt, resulting in poor anti-slip effect or no anti-slip effect at all.

[0006] 2). It also does not solve the technical problem of the metal anti-slip sheet maintaining its correct position. Summary of the Invention

[0007] The object of the present invention is to provide an anti-drop socket to solve the above problem.

[0008] The above-mentioned purpose of the present invention is achieved by the following technical means:

[0009] The present invention discloses an anti-dropout socket, which is formed by a top cover 1 covering a bottom cover 2, and the socket is further provided with an anti-dropout mechanism 4;

[0010] The anti-slip mechanism 4 includes: a partition 5 fixed between the top cover 1 and the bottom cover 2, an elastic support seat 6 provided between the partition 5 and the top cover 1, and an anti-slip sheet 8;

[0011] The front cover 1, the anti-drop sheet 8, the elastic support seat 6, the partition 5, and the bottom cover 2 are all provided with first sockets 3 corresponding to each other; the front cover 1, the partition 5, and the bottom cover 2 are all provided with other sockets corresponding to each other; the first socket 3 and other sockets of the bottom cover 2 are provided with electrical contacts 31;

[0012] The elastic support seat 6 has left and right arms 61, and the bottoms of the left and right arms 61 are provided with left and right springs 62. The left and right arms 61 contact the cover 1 under the action of elastic force, and the left arm is provided with a button 63 extending out of the cover 1; the partition 5 is provided with a slot 51 for fitting with the left and right springs 62;

[0013] A button hole 12 and a pressing piece 11 for keeping the anti-slip piece 8 tilted in its initial state are provided below the cover 1 .

[0014] The elastic support seat 6 has a placement groove 64 in the middle portion for assembling the anti-slip sheet 8. The bottom of the placement groove 64 is provided with a fulcrum 641 and the first insertion hole 3. One inner side of the placement groove 64 corresponding to the fulcrum 641 is provided with a side clamping groove 642 for limiting the upward and downward movement space of one end of the anti-slip sheet 8. The pressing sheet 11 extends from the other inner side of the placement groove 64 to the lower part of the placement groove 64 and blocks the other end of the anti-slip sheet 8.

[0015] A beam frame 66 is further provided in the placement groove 64. The beam frame 66 includes two side beams and a lower beam. The lower beam is the fulcrum 641. Sockets 81 for inserting the side beams are provided on both sides of the anti-slip sheet 8.

[0016] The first insertion hole 3 of the partition 5 is slightly larger than the outer size of the placement slot 64. When the placement slot 64 obliquely reaches or further extends into the first insertion hole 3 of the partition 5, the insertion hole prevents the placement slot 64 from moving around.

[0017] Preferably, the right arm is provided with a positioning column 65, and a positioning hole 13 is provided under the face cover 1 to cooperate with the positioning column 65. The button 63 of the left arm extending out of the face cover 1 and the positioning column 65 of the right arm together constitute a positioning mechanism of the elastic support seat 6 to prevent the elastic support seat 6 from moving around.

[0018] Preferably, a limiting groove 14 is further provided under the cover 1 to limit the placement groove 64 from moving around. The limiting groove 14 has left and right openings 141 , and the left and right arms 61 of the elastic supporting seat 6 are clamped in the left and right openings 141 .

[0019] Preferably, the cover 1 is further provided with a snap-fitting groove 15 , and the partition 5 is snap-fitted to the cover 1 through the snap-fitting groove 15 .

[0020] Preferably, the bottom cover 2 and the partition 5 are both provided with corresponding stud holes 21 , and studs 16 are provided under the surface cover 1 . The surface cover 1 is locked with the partition 5 and the bottom cover 2 by bolts through the studs 16 and the stud holes 21 .

[0021] Preferably, left and right spring plug-in columns 611 are further provided at the bottom of the left and right arm portions 61 , and the left and right spring plug-in columns 611 are plugged into the left and right springs 62 .

[0022] Preferably, the anti-drop socket includes at least one of a two-pin socket and a three-pin socket.

[0023] The beneficial effects of adopting the above technical solution are:

[0024] 1. When a plug is inserted into the socket, the left arm of the elastic support seat adaptively adjusts downward to reduce the inclination of the anti-slip plate so that the first pin is normally inserted into the first socket of the socket. The elastic support seat resets under the action of the spring, so that the anti-slip plate resumes its inclined state in the seesaw mechanism. The first socket of the anti-slip plate tightly engages the first pin to prevent the plug from falling off, and normal external force cannot pull the plug out of the socket; pressing the button to tilt the elastic support seat to adjust and reduce the inclination of the anti-slip plate in the seesaw mechanism, the first socket of the anti-slip plate releases the tight clamping force on the first pin, and the plug can be easily pulled out of the socket with normal external force. The elastic supporting seat of the present invention has a left arm and a right arm, and the bottom of the left arm and the right arm are provided with a left spring and a right spring. The left arm and the right arm contact the surface cover under the action of elastic force, and the anti-slip sheet applies or releases the tight clamping force on the first pin mainly by the left arm pressing the left spring downward or releasing the pressure on the spring. After long-term use, even if the elastic force of the left spring weakens, the right spring is sufficient to support the entire elastic supporting seat to reset. Therefore, the user experience of this anti-slip socket after long-term use may only be that the button is easier to press, but the anti-slip socket can still apply a tight clamping force to the first pin.

[0025] 2. The anti-sheet-slip rocker mechanism tilts internally or adaptively reduces the tilt.

[0026] 3. The anti-slip piece is inserted into the support point of the beam frame to ensure that the anti-slip piece always moves in the seesaw mechanism, preventing the anti-slip piece from moving in the placement groove and ensuring that the first insertion hole of the anti-slip piece is in the correct position.

[0027] 4. The first insertion hole of the partition prevents the placement slot from moving around and ensures that the first insertion hole of the anti-slip sheet is in the correct position.

[0028] 5. The button on the left arm extending out of the cover and the positioning column on the right arm together constitute a positioning mechanism of the elastic support seat, preventing the elastic support seat from moving around and ensuring that the first insertion hole of the anti-slip plate is in the right position.

[0029] 6. The limiting groove restricts the placement groove from moving around to ensure that the first insertion hole of the anti-drop plate is in the correct position. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Example 1. Figure 1-13 A socket with an anti-dropout function is shown, which is formed by a top cover 1 covering a bottom cover 2, and is characterized in that the socket is further provided with an anti-dropout mechanism 4;

[0045] The anti-slip mechanism 4 includes: a partition 5 fixed between the top cover 1 and the bottom cover 2, an elastic support seat 6 provided between the partition 5 and the top cover 1, and an anti-slip sheet 8;

[0046] The front cover 1, the anti-drop sheet 8, the elastic support seat 6, the partition 5, and the bottom cover 2 are all provided with first sockets 3 corresponding to each other; the front cover 1, the partition 5, and the bottom cover 2 are all provided with other sockets corresponding to each other; the first socket 3 and other sockets of the bottom cover 2 are provided with electrical contacts 31;

[0047] The elastic support seat 6 has left and right arms 61, and the bottoms of the left and right arms 61 are provided with left and right springs 62. The left and right arms 61 contact the cover 1 under the action of elastic force, and the left arm is provided with a button 63 extending out of the cover 1; the partition 5 is provided with a slot 51 for fitting with the left and right springs 62;

[0048] A button hole 12 and a pressing piece 11 for keeping the anti-slip piece 8 tilted in its initial state are provided below the cover 1 .

[0049] When a plug is inserted into the socket, the first pin of the plug reaches the first insertion hole 3 of the anti-dropout plate 8 in the tilted state and is blocked, which further presses the anti-dropout plate 8 downward. The anti-dropout plate 8 is tilted up from the tilted state in the seesaw mechanism 7, and at the same time, the left arm of the elastic support seat 6 is adaptively adjusted downward, so that the tilt of the anti-dropout plate 8 becomes smaller. The first pin passes through the anti-dropout plate 8, the elastic support seat 6, the partition 5 and the first insertion hole 3 of the bottom cover 2 normally, and finally enters the electrical contact 31 in the insertion hole.

[0050] After the plug is connected, the elastic support seat 6 is reset under the action of the spring, so that the anti-dropping plate 8 returns to the tilted state in the rocker mechanism 7. The first socket 3 of the anti-dropping plate 8 is tightly engaged with the first pin to prevent the plug from falling off. Normal external force cannot pull the plug out of the socket.

[0051] When it is necessary to unplug the plug, the left arm presses the left spring downward by pressing the button 63, so that the elastic support seat 6 tilts to adjust and reduce the inclination of the anti-slip plate 8 in the rocker mechanism 7. The first socket 3 of the anti-slip plate 8 releases the tight clamping force on the first pin, and the plug can be easily unplugged from the socket with normal external force.

[0052] In the present invention, the elastic supporting seat 6 has left and right arm parts 61, and the bottom of the left and right arm parts 61 are provided with left and right springs 62. The left and right arm parts 61 contact the cover 1 under the action of elastic force, and the anti-slip sheet 8 applies or releases the tight clamping force on the first pin mainly by pressing the left spring downward or releasing the pressure on the spring by the left arm. After long-term use, even if the elastic force of the left spring weakens, the right spring is sufficient to support the entire elastic supporting seat 6 to reset. Therefore, the user experience of this anti-slip socket after long-term use may only be that the button 63 is easier to press, but the anti-slip socket can still apply a tight clamping force to the first pin.

[0053] It should be noted that the elastic supporting seat 6 is made of a lightweight material, generally a lightweight plastic or aluminum member.

[0054] Example 2. This example is based on Example 1. Figure 2-3 As shown, the elastic supporting seat 6 has a placement groove 64 for assembling the anti-slip sheet 8 in the middle, and a fulcrum 641 and the first plug hole 3 are provided at the bottom of the placement groove 64. One of the inner sides of the placement groove 64 corresponding to the fulcrum 641 is provided with a side clamping groove 642 for limiting the upward and downward movement space of one end of the anti-slip sheet 8. The pressing sheet 11 extends from the other inner side of the placement groove 64 to the lower part of the placement groove 64 and blocks the other end of the anti-slip sheet 8.

[0055] For example, Figure 8-13 As shown, when the plug is inserted into the socket, the first pin of the plug reaches the first socket 3 of the anti-slip plate 8 in the tilted state and is blocked, and the left end of the anti-slip plate 8 is further pressed downward to move toward the lower direction in the side slot 642. Under the action of the fulcrum 641, the right end of the anti-slip plate 8 is tilted and presses the pressing plate 11, thereby causing the left arm of the elastic support seat 6 to adaptively adjust downward, so that the tilt amplitude of the anti-slip plate 8 becomes smaller, and the first pin passes through the anti-slip plate 8, the elastic support seat 6, the partition 5 and the first socket 3 of the bottom cover 2 normally, and is finally inserted into the electric contact 31 in the socket; after the insertion is completed, the elastic support seat 6 is reset under the action of the spring, so that the anti-slip plate 8 returns to the tilted state in the seesaw mechanism 7, and the first socket 3 of the anti-slip plate 8 is tightly clamped with the first pin to prevent the plug from falling off. Normal external force cannot pull the plug out of the socket;

[0056] When it is necessary to unplug the plug, the left arm presses the left spring downward by pressing the button 63, so that the side slot 642 presses the left end of the anti-slip plate 8 downward to adjust and reduce the inclination of the anti-slip plate 8 in the seesaw mechanism 7 during the tilting process of the elastic support seat 6. The first socket 3 of the anti-slip plate 8 releases the tight clamping force on the first pin, and the plug can be easily unplugged from the socket with normal external force.

[0057] Example 3. This example is based on Example 2. Figure 2-5As shown, a beam frame 66 is further provided in the placement groove 64 , and the beam frame 66 includes two side beams and a lower beam, the lower beam is the fulcrum 641 , and insertion holes 81 for inserting the side beams are provided on both sides of the anti-slip sheet 8 .

[0058] The anti-slip sheet 8 is inserted into the beam frame 66 and contacts the fulcrum 641 to ensure that the anti-slip sheet 8 always moves in the seesaw mechanism 7, preventing the anti-slip sheet 8 from moving in the placement groove 64 and ensuring that the first insertion hole 3 of the anti-slip sheet 8 is in the correct position.

[0059] Example 4. This example is based on Example 2. Figure 1-7 As shown, the size of the first insertion hole 3 of the partition 5 is slightly larger than the outer size of the placement groove 64. When the placement groove 64 is tilted downward to reach or even further extend into the first insertion hole 3 of the partition 5, the first insertion hole 3 of the partition 5 prevents the placement groove 64 from moving around and ensures that the first insertion hole 3 of the anti-slip sheet 8 is in the correct position.

[0060] Example 5. This example is based on Example 1. Figure 2-5 As shown, the right arm is provided with a positioning column 65, and a positioning hole 13 is provided under the cover 1 to cooperate with the positioning column 65. The button 63 of the left arm extending out of the cover 1 and the positioning column 65 of the right arm together constitute a positioning mechanism of the elastic support seat 6, which prevents the elastic support seat 6 from moving around and ensures that the first socket 3 of the anti-slip sheet 8 is in the correct position.

[0061] Example 6. This example is based on Example 2. Figure 3-5 As shown, a limiting groove 14 is further provided under the cover 1 to limit the placement groove 64 from moving around. The limiting groove 14 has left and right openings 141.

[0062] The left and right arms 61 of the elastic supporting seat 6 are clamped in the left and right openings 141, and the placement groove 64 of the elastic supporting seat 6 is assembled in the limiting groove 14 of the cover 1. The limiting groove 14 restricts the placement groove 64 from moving around to ensure that the first insertion hole 3 of the anti-slip plate 8 is in the right position.

[0063] Example 7. Exemplary, such as Figure 4 As shown, the top cover 1 is further provided with a snap-fitting groove 15 , and the partition 5 is snap-fitted to the top cover 1 through the snap-fitting groove 15 to complete pre-fixation and then assembled to the bottom cover 2 .

[0064] Example 8. Exemplary, such as Figure 6 As shown, the bottom cover 2 and the partition 5 are both provided with corresponding stud holes 21 , and studs 16 are provided under the surface cover 1 . The surface cover 1 is locked with the partition 5 and the bottom cover 2 by bolts through the studs 16 and the stud holes 21 .

[0065] Example 9. This example is based on Example 1. Figure 2As shown, the bottom of the left and right arms 61 is further provided with left and right spring plug posts 611, which are plugged into the left and right springs 62. Similarly, the plug posts 611 can be replaced with jacks or slots to connect the springs.

[0066] Example 10. This example is based on Example 1, and the anti-drop socket includes at least a two-pin socket or a Figure 13 One of the three-pin sockets shown.

[0067] It should be noted that with the development of technology, plugs with four or more pins may appear. Based on the present invention, the socket can also be changed to a socket with four or more pins to solve the need to prevent the plug from falling off.
