Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connection components, in particular to an automatic locking structure of an electrical connection interface. BACKGROUND

[0002] In the prior art, electrical connection interfaces are widely used in various scenarios requiring circuit conduction, such as electrical equipment, industrial control, communication equipment, etc. The core structure of the electrical connection interface is mainly composed of a plug and a socket. To ensure the stability of the basic connection, some interfaces are provided with simple locking components (such as buckles, elastic sheets) or protective components (such as rubber dustproof sleeves). The locking components mainly achieve the fixation of the plug and the socket through manual pressing or rotation, and the protective components need to be manually fitted on the outside of the interface after the plug is inserted to block the intrusion of impurities such as dust and water vapor. Most structures also design a shell with multiple sockets integrated to meet the demand of connecting multiple circuits simultaneously.

[0003] The existing electrical connection interface structure has obvious defects. On the one hand, the locking structure relies on manual operation, and the plugging and unplugging process is cumbersome. When subjected to external force, the interface lacks effective buffer protection, and the plug and socket are easily separated rigidly, causing the pins to bend and the socket to be damaged, which further leads to circuit interruption or poor contact. On the other hand, the protective component and the locking structure are independent of each other. After the plug is locked, the protective component needs to be activated through additional operation, which is not convenient to operate. Moreover, the protective component can only achieve basic dustproofing and cannot protect the bending of the connection between the plug and the socket, which may lead to wire breakage after long-term use. In addition, when multiple sockets are integrated, each socket lacks an independent buffer mechanism, and when a single socket is affected by external force, it may cause other sockets to deviate, affecting the connection stability of the overall interface. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides an automatic locking structure of an electrical connection interface to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present application realizes the following technical scheme: an automatic locking structure of an electrical connection interface, comprising a shell, a plurality of sockets slidably connected inside the shell, a plug inserted inside the socket, a buffer mechanism installed inside the shell and cooperating with the socket, an automatic locking mechanism installed inside the socket and cooperating with the plug, and a protective mechanism inside the socket and cooperating with the plug. The socket comprises a sliding seat slidably connected inside the shell, and the inner wall of the sliding seat is fixedly connected with pins cooperating with the plug. The plug comprises a plug-in part inserted inside the sliding seat, and the inside of the plug-in part is provided with a socket cooperating with the pins. One end of the plug-in part is fixedly connected with a hand-held part. The automatic locking mechanism comprises L-shaped grooves opened on both sides of the socket, and the two L-shaped grooves are communicated at one end, and J-shaped clamping plates are slidably connected in the two L-shaped grooves, and clamping grooves matched with the J-shaped clamping plates are formed on both sides of the plug-in part, and a second spring is fixedly connected between the J-shaped clamping plate and the inner wall of the L-shaped groove.

[0006] Preferably, the buffer mechanism comprises connecting ears symmetrically fixedly connected on both sides of the sliding seat, a guide rod is fixedly connected in the shell and slidably connected with the connecting ears, and a first spring is arranged outside the guide rod to provide buffer protection when the plug is stretched.

[0007] Preferably, a push rod is slidably connected through the top of the socket, the bottom end of the push rod is in isosceles trapezoidal structure, an inclined surface matched with the bottom end of the push rod is formed at one end of the J-shaped clamping plate, a T-shaped pressing rod matched with the push rod is limitingly and slidably connected through the top of the shell, and the two J-shaped clamping plates are conveniently pushed to move to realize unlocking.

[0008] Preferably, the protection mechanism comprises a meandering groove opened at the front end of the sliding seat, a protection cover is slidably connected in the meandering groove, a sealing ring matched with the handheld part is fixedly connected to the inner wall of the protection cover, and extrusion blocks matched with one end of the J-shaped clamping plate are fixedly connected to both sides of one end of the protection cover, so that the plug can be shielded and protected when the plug is inserted.

[0009] Preferably, two embedding grooves are symmetrically formed in the rear side of the sliding seat, a third spring is mounted in the embedding groove, a stop block is fixedly connected to one end of the third spring, a pull rope is fixedly connected between one end of the stop block and one side of the protection cover, and a slide channel matched with the pull rope is formed in the sliding seat, so that the protection cover is conveniently reset.

[0010] Preferably, an arc surface matched with the extrusion block is arranged at one end of the J-shaped clamping plate, so that the extrusion block is conveniently extruded to move the protection cover.

[0011] The application provides an automatic locking structure of an electrical connection interface. The automatic locking mechanism can automatically clamp after the plug is inserted, without manual operation, and the plug-pull convenience is greatly improved. The buffer mechanism can provide sliding buffer for the socket through the elastic deformation of the first spring and the guidance of the guide rod when the plug is pulled, so as to avoid rigid damage to the interface and effectively protect the contact stability of the pin and the socket. The protective mechanism is linked with the automatic locking mechanism. When the plug is locked, the protective cover automatically closes and works with the sealing ring to achieve a sealed protection while preventing the plug from bending. When the plug is pulled out, the protective cover automatically resets under the action of the third spring and the pull rope. The protection process does not require additional intervention. Multiple sockets are independently arranged within the housing, and each socket is equipped with a dedicated buffer, locking, and protective structure. This ensures overall neatness and prevents the use of a single interface from affecting other interfaces, significantly extending the overall structural lifespan and improving the stability and safety of electrical connections.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0015] like Figures 1 to 5 As shown, an automatic locking structure for an electrical connection interface includes a housing 1. Multiple sockets 2 are slidably inserted into the interior of the housing 1. A plug 3 is inserted into the interior of each socket 2. Each socket 2 includes a sliding seat 21 slidably connected inside the housing 1. The inner wall of the sliding seat 21 is fixedly connected to pins 22 that mate with the plug 3. The plug 3 includes a plug portion 31 inserted into the interior of the sliding seat 21. The interior of the plug portion 31 has a socket that mates with the pins 22. One end of the plug portion 31 is fixedly connected to a handle portion 32.

[0016] The connection method of plug 2 and socket 3 in this technical solution is a conventional electrical connection. The pins 22 inside plug 2 cooperate with the inner wall of the plug portion 31 on plug 3 to realize the conduction of the circuit.

[0017] like Figure 2 and Figure 3 As shown, a buffer mechanism 4 that cooperates with the socket 2 is installed inside the housing 1. The buffer mechanism 4 includes connecting ears 41 that are symmetrically fixedly connected to both sides of the sliding seat 21. A guide rod 42 that is slidably connected to the connecting ears 41 is fixedly connected inside the housing 1. A first spring 43 is sleeved on the outside of the guide rod 42.

[0018] After the plug 3 is inserted into the socket 2, if the plug 3 is accidentally pulled, the socket 2 can move a certain distance with the plug 3 with the cooperation of the first spring 43, so as to avoid the plug 3 being rigidly pulled and thus play a protective role.

[0019] like Figure 4 and Figures 6 to 8 As shown, the socket 2 is equipped with an automatic locking mechanism 5 that cooperates with the plug 3. The automatic locking mechanism 5 includes L-shaped grooves on both sides of the socket 2, and one end of the two L-shaped grooves is connected to each other. J-shaped plates 51 are slidably connected inside the two L-shaped grooves. The plug part 31 has slots 52 on both sides that cooperate with the J-shaped plates 51. A second spring 53 is fixedly connected between one side of the J-shaped plate 51 and the inner wall of the L-shaped groove.

[0020] When the plug 3 is inserted into the socket 2, when the slot 52 coincides with one end of the J-type card plate 51, the J-type card plate 51 will be locked into the slot 52 under the action of the second spring 53, thereby realizing the automatic locking of the plug 3 and preventing it from being released.

[0021] A push rod 54 is slidably connected through the top of the socket 2. The bottom end of the push rod 54 is an isosceles trapezoidal structure. One end of the J-shaped plate 51 is provided with an inclined surface that matches the bottom end of the push rod 54. A T-shaped pressure rod 55 that matches the push rod 54 is slidably connected through the top of the housing 1.

[0022] When it is necessary to remove plug 3, simply press the T-shaped lever 55, which will drive the push rod 54 to squeeze the two J-shaped plates 51. With the cooperation of the inclined plane, the two J-shaped plates 51 can move relative to each other, so that one end of the J-shaped plate 51 moves out of the slot 52, and then plug 3 can be pulled out.

[0023] like Figures 6 to 9 As shown, the socket 2 has a protective mechanism 6 inside that mates with the plug 3. The protective mechanism 6 includes a U-shaped groove at the front end of the sliding seat 21. A protective cover 61 is slidably connected inside the U-shaped groove. A sealing ring 62 that mates with the handle part 32 is fixedly connected to the inner wall of the protective cover 61. Both sides of one end of the protective cover 61 are fixedly connected to pressing blocks 66 that mate with one end of the J-shaped clamping plate 51. One end of the J-shaped clamping plate 51 has an arc-shaped surface that mates with the pressing block 66.

[0024] After the plug 3 is inserted into the socket 2, the J-shaped locking plate 51 will be locked into the slot 52 under the action of the second spring 53. At this time, the J-shaped locking plate 51 will squeeze the squeezing block 66, thereby pushing the protective cover 61 to move outward. Together with the sealing ring 62, it can cover the handle part 32 of the socket 3, which can not only play a sealing protection role, but also prevent the plug 3 from being bent and protect the plug 3.

[0025] The sliding seat 21 has two symmetrically arranged grooves on the rear side inside. A third spring 63 is installed inside the groove. One end of the third spring 63 is fixedly connected to a stop 64. One end of the stop 64 is fixedly connected to a pull rope 65 between it and one side of the protective cover 61. The sliding seat 21 has a slide that cooperates with the pull rope 65 inside.

[0026] When the plug 3 is inserted into the socket 2, the plug part 31 of the plug 3 will press against the stop 64, and the pull rope 65 will loosen, allowing the protective cover 61 to move normally. When the plug 3 is pulled out, the stop 64 will automatically reset with the cooperation of the third spring 63 and pull the pull rope 65, so that the protective cover 61 is retracted.

[0027] Working principle: When in use, align the plug 31 of the plug 3 with the sliding seat 21 of the socket 2 and insert it. During the insertion process, the plug 31 presses the stop 64 inside the sliding seat 21, causing the stop 64 to compress the third spring 63 and pull the pull rope 65. The pull rope 65 is in a loose state. As the insertion part 31 continues to penetrate deeper, when the slots 52 on both sides of the insertion part 31 align with the J-shaped locking plate 51 in the L-shaped groove inside the sliding seat 21, the J-shaped locking plate 51 slides towards the slot 52 under the elastic force of the second spring 53, and finally locks into the slot 52, completing the automatic locking of the plug 3 and the socket 2; at the same time, the J-shaped locking plate 51 presses the pressing blocks 66 at both ends of the protective cover 61 through its own arc surface, pushing the protective cover 61 to move outward along the U-shaped groove at the front end of the sliding seat 21 until the protective cover 61 covers the outside of the handle part 32 of the plug 3, and the sealing ring 62 on the inner wall of the protective cover 61 fits against the handle part 32, achieving sealing protection; If the plug 3 is accidentally pulled, the sliding seat 21 of the socket 2 will slide along the guide rod 42 inside the housing 1 through the connecting ears 41 on both sides. The first spring 43 on the outside of the guide rod 42 undergoes elastic deformation to provide buffer for the pulling force and avoid rigid damage to the interface. When plug 3 needs to be unplugged, press the T-shaped lever 55 on the top of housing 1. The T-shaped lever 55 pushes the push rod 54 on the top of socket 2 downward. The isosceles trapezoidal structure at the bottom of push rod 54 squeezes the two J-shaped plates 51 through the inclined surface on the J-shaped plate 51, so that the two J-shaped plates 51 overcome the elastic force of the second spring 53 and move relative to each other, disengaging from the slot 52 of plug part 31. At this time, plug 3 can be directly unplugged. After plug 3 is unplugged, the third spring 63 returns to its original shape and pushes the stop block 64 to reset. The stop block 64 pulls the protective cover 61 along the loop groove to return to the inside of the sliding seat 21 via the pull rope 65, completing the entire usage cycle.
