Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a push-pull locking waterproof signal plug and its socket. Background Technology

[0002] With the increasing use and prevalence of electronic products in open-air and outdoor environments, the waterproofing requirements for connectors are becoming increasingly stringent. Existing waterproof connectors come in a variety of structures and forms. Common waterproofing measures include: installing a sealing ring or groove between the connector shell and the main housing to achieve interface waterproofing; installing potting compound between the rear end of the connector shell and the insulating body to achieve internal sealing; and installing a wire cover on the wire lead-out surface and establishing a sealing structure between the cover and the shell. However, these structures often have the following drawbacks:

[0003] 1. Exposed Lock Hook Arrangement: Most existing locking connectors have their lock hooks exposed outside the housing; when not docked, the lock hooks are directly exposed to the environment, making them prone to dust and water ingress, impact and wear, oxidation and rust, causing locking failure;

[0004] 2. Defects of external full-coverage rubber sleeve protection: Some products rely on external full-coverage rubber sleeves for overall protection; the rubber sleeve is exposed and is easily scratched, bumped and damaged; affected by ultraviolet rays and temperature cycles, the rubber ages and loses elasticity, the sealing ability decreases, and moisture can penetrate into the connector; at the same time, the rubber sleeve will increase the radial outer diameter of the product, resulting in a poor appearance and texture.

[0005] 3. Cumbersome threaded locking operation: Threaded locking connectors have high sealing reliability, but docking and disassembly require multiple rotations, making it impossible to quickly insert or remove with one hand. Maintenance and disassembly are time-consuming and not suitable for working conditions that require frequent disassembly and assembly.

[0006] 4. No fault tolerance due to seal failure: If the seal of the existing quick-lock connector is worn and leaks water, the water will directly reach the lock hook and spring moving parts, causing the locking to jam and fail, without any fault buffer or fault tolerance.

[0007] Therefore, technicians need to develop a waterproof signal plug with a push-pull locking mechanism that is compact in structure, has excellent sealing and waterproof performance, and is simple and efficient to operate. Summary of the Invention

[0008] This invention addresses the primary technical problem that existing technologies aim to solve by providing a push-pull locking waterproof signal plug. It features a compact structure, reliable locking, and strong waterproof performance. Furthermore, the entire locking and releasing process requires only a linear reciprocating drive, making it easy to operate.

[0009] This invention addresses another technical problem that the prior art seeks to solve by providing a related matching socket.

[0010] The technical solution of this invention to solve the primary technical problem is: a push-pull locking waterproof signal plug, comprising a housing, a waterproof clamp, a screw sleeve, and a waterproof ring. The front middle part of the housing contains an adapter for fixing the signal connector and a waterproof clamp for fixing the cable. A waterproof ring is provided in the rear part of the waterproof clamp. The rear part of the housing is threadedly connected to the screw sleeve. An annular fixing groove is arranged on the outer wall of the housing, and a collar is riveted to the annular fixing groove. The housing has an internal sliding groove, and the collar has sliding holes at corresponding positions. The sliding groove allows the internal push-pull component to slide back and forth. A button is fixed on the top of the device. The front of the sliding groove is connected to the latch mounting hole on the outer shell through a connecting hole. A latch with a locking hook is rotatably installed in the latch mounting hole. The latch is entirely inside the outer shell. The front end of the built-in push-pull part is connected to the push-pull part through a connecting part. The push-pull part has a concave push-pull groove, which is in a movable push-pull engagement with the downwardly extending push block at the rear end of the latch. An elastic element is arranged at the front end of the built-in push-pull part to keep it always sliding backward. There is a sliding seal between the connecting part and the connecting hole. The front end face and surface of the collar have a waterproof ring for sealing.

[0011] Furthermore, the rotatable installation means that the locking element has axle pins on both sides, and the corresponding locking mounting holes have open shaft holes on both sides, which cooperate to realize the rotation and swing of the locking element.

[0012] Furthermore: The elastic element is a spring, which is sleeved on the connecting part and supported between the front end of the built-in push-pull element and the front wall of the sliding groove. The spring always applies a backward thrust to achieve the locking tendency of the locking element.

[0013] Furthermore, the rear of the built-in push-pull component is provided with a snap-fit ​​groove, and the bottom of the corresponding button is provided with a snap-fit ​​block to achieve snap-fit ​​fixation.

[0014] Furthermore, the outer wall of the connecting part is provided with a first annular sealing groove, and a first sealing ring is fixed in the first annular sealing groove to achieve sliding sealing between the connecting part and the connecting hole.

[0015] Furthermore, the front surface of the collar is provided with an annular mounting groove, and the front end of the annular mounting groove is provided with an annular positioning groove. The waterproof ring is a toothed waterproof ring, which is made of sealing elastic material and has multiple annular sealing teeth distributed on its surface. It cooperates with the inner wall of the socket hole to achieve contact sealing. A sealing positioning ring extends inward along the inner side of the front port and is positioned and fixed in the annular positioning groove, so that the toothed waterproof ring is fixed at the front of the collar, realizing the sealing and waterproof function between the collar and the outer shell.

[0016] Furthermore, the waterproof clamp is provided with a second annular sealing groove, and a second sealing ring is fixed in the second annular sealing groove to realize the waterproof function between the outer shell and the waterproof clamp.

[0017] Furthermore, the bottom of the sliding hole is provided with an installation groove, and the size of the corresponding sealing sheet matches it, thereby achieving the waterproof function of the button area.

[0018] Furthermore, the annular fixing groove has a third annular sealing groove between the locking mounting hole and the sliding groove, lined with a third sealing ring, to achieve a sealing and waterproof function between the collar and the outer shell.

[0019] Finally, a guide limiting block is provided at the bottom of the sliding groove, which cooperates with the guide groove at the bottom of the built-in push-pull component.

[0020] The technical solution of the present invention to solve another technical problem is: a socket that is compatible with any of the push-pull locking waterproof signal plugs described above. It includes a socket, a plug portion for receiving signal connectors in the socket, and a locking groove or locking hole on the surface of the plug portion for cooperating with the locking hook of the locking member.

[0021] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] 1. The locking mechanism adopts a fully built-in protective design: the locking mechanism is completely stored inside the plug's outer shell, preventing external bumps and wear when not in the plugged-in state; after the plug and socket are plugged in, the area where the locking mechanism is located forms a closed space, making it difficult for dust and moisture to come into contact with the moving parts of the locking mechanism, thus improving the reliability and service life of the locking mechanism.

[0023] 2. Elimination of external full-coverage rubber sleeve: The plug body adopts a zinc alloy shell with a stainless steel collar, with only the push-pull button protruding; dynamic sealing is achieved by relying on the internal sealing ring of the shell; avoiding the failure risk caused by the external rubber sleeve being bumped, damaged, aged, or losing elasticity; compared with the shell-equipped solution and the side button structure, the overall shaft diameter is smaller, and the metal shell has a better appearance and texture;

[0024] 3. Quick push-pull locking, balancing sealing and operational efficiency: Unlike threaded tightening structures, unlocking and plugging can be completed by pushing and pulling the button axially, enabling quick one-handed assembly and disassembly, balancing sealing reliability and ease of operation;

[0025] 4. Intermediate connection sealing fault tolerance structure: The button, the built-in push-pull component, and the locking component are three separate and independent parts; the sealing ring is arranged on the outer periphery of the connection part of the built-in push-pull component; even if the sealing sheet wears and a small amount of water seeps in, the seepage is blocked on the outside of the built-in push-pull component and will not invade the locking movement pair of the locking component, thus having the fault tolerance capability for sealing failure.

[0026] Axial pushing and pulling is achieved by sliding the button, which drives the built-in push-pull component to swing the locking component. At the same time, the entire locking process can be completed by driving the built-in push-pull component to move in a single straight line. The locking structure is completely housed inside the housing, making it compact, reliable, not easily damaged, and easy to operate. It is especially suitable for control scenarios that require quick locking and releasing, and has multiple waterproof features. Attached Figure Description

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] SeeFigures 1 to 12A push-pull locking waterproof signal plug includes main components such as a housing 1, a collar 2, a waterproof clamp 3, a screw sleeve 4, and a waterproof ring 5. The housing 1 is typically made of zinc alloy to maintain sufficient strength. The front section of the housing 1 contains an adapter 35 for fixing the signal connector 38 and a waterproof clamp 3 for fixing the cable 46. In this embodiment, the adapter 35 is divided into two parts: a left adapter component 37 and a right adapter component 36. The left adapter component 37 and the right adapter component 36 are assembled to form a complete adapter 35, which can fix the signal connector 38 in the adapter 35. The right adapter component 36 is usually integrated with the waterproof clamp 3 for easy production and assembly. Then, the connector 38 is attached to the adapter. The adapter 35 and its waterproof clamp 3 are positioned and fixed within the mounting chamber 42 of the housing 1. Typically, the mounting chamber 42 of the housing 1 is divided into three sections according to a partition section or partition plate: front chamber 42a, middle chamber 42b, and rear chamber 42c. The front chamber 42a houses the contact portion 38a of the signal connector 38; the middle chamber 42b houses the adapter 35, its signal connector body 38b installed within the adapter 35, and the front portion of the waterproof clamp 3; the rear chamber 42c houses the rear portion of the waterproof clamp 3 and the waterproof ring 5, which is located within the waterproof clamp 3. Furthermore, an annular fixing groove 30 is arranged on the outer wall of the housing 1, approximately on the outer surface of the middle chamber 42b. A collar 2 is riveted onto the outer shell 1 to achieve a preliminary sealing and waterproofing effect. The rear section of the outer shell 1 is threadedly connected to the screw sleeve 4. At the same time, the screw sleeve 4 also has a certain limiting effect on the collar 2. The signal connector 38 and its cable 46 are fixed inside the outer shell 1 through the adapter 35 and the waterproof clamp 3. The key point of the invention is that the outer shell 1 also has a built-in, axially extending sliding groove 6 on the upper surface of the annular fixing groove 30. The sliding groove 6 is roughly located in the middle section cavity 42b area. The collar 2 has a rectangular sliding hole 7 at the corresponding position. There is a built-in push-pull member 8 in the sliding groove 6 on the lower side of the bottom of the sliding hole 7, which allows the built-in push-pull member 8 to slide back and forth. A button 9 is fixed to the top of the rear section of the built-in push-pull member 8. The button 9 extends upward and protrudes above the sliding hole 7. The annular fixing groove 30 at the front of the 6 is also provided with a latch mounting hole 10. The latch mounting hole 10 is located in the front area of ​​the middle section chamber 42b, so that the latch mounting hole 10 can communicate with the front section chamber 42a forward and with the sliding groove 6 through the connecting hole 31 backward. Open shaft holes 32 are arranged on both sides of the latch mounting hole 10, so that the latching member 11 can be rotatably fixed in the latch mounting hole 10, so that the latching member 11 is entirely inside the outer shell 1. The front side of the built-in push-pull member 8 is the connecting part 12, which is in sliding fit with the connecting hole 31. In front of the connecting part 12 is the push-pull part 14. The built-in push-pull member 8, the connecting part 12 and the push-pull part 14 are made into one piece to facilitate assembly and production. The outer wall of the connecting part 12 is provided with a first annular sealing groove 19.The first sealing ring 20 is fixed in the first annular sealing groove 19 to achieve sliding seal between the connecting part 12 and the connecting hole 31. The upper surface of the push-pull part 14 has a concave push-pull groove 13. The front side of the push-pull groove 13 is a forward-inclined inclined wall, and the rear side is a backward-inclined inclined wall, presenting a roughly inverted trapezoidal groove. The main body of the locking element 11 is flat. It has a downward-extending locking hook 24 with a guide surface at the front end and a downward-extending push block 33 at the rear end. The push block 33 extends into the push-pull groove 13, forming a movable push-pull engagement. The rear ends of the locking element 11 have pins 15 on both sides, which can be installed in the open shaft holes 32 on both sides of the locking mounting hole 10, forming a rotating connection. Thus, when the built-in push-pull element 8 is axially pushed or pulled along the sliding groove 6, the front end of the connecting part 12, through the concave push-pull groove 13, interacts with the push block 33 at one end of the locking element 11, converting it into a rotating and swinging motion that drives the locking element 11 to rotate its locking hook 24 and wedge it into the locking groove 41 or locking hole of the socket B.

[0044] The top of the built-in push-pull component 8 is provided with a snap-fit ​​groove 17, and the bottom of the corresponding button 9 is provided with a snap-fit ​​block 34. The button 9 is fixed to the built-in push-pull component 8 by snap-fit. When the user pushes the button 9 to slide in the sliding hole 7, it causes the built-in push-pull component 8 in the sliding groove 6 to move together. The locking component 11 is provided with axle pins 15 on both sides, and the corresponding locking mounting hole 10 is provided with open shaft holes 32 for positioning on both sides. The axle pins 15 on both sides of the locking component 11 are fixed inside, so that the locking hook 24 of the locking component 11 can rotate and swing along the axle pins 15. A spring 16 is sleeved on the connecting part 12 as an elastic element. The spring 16 is supported between the front end of the built-in push-pull component 8 and the front wall of the sliding groove 6. In this way, the spring 16 always applies a backward thrust, so that the locking component 11 always maintains a counterclockwise rotation trend and is in a locked state. The locking hook 24 always relies on the force of the spring 16 to firmly lock the locking component 11 to the locking groove 41 or locking hole of the socket B. The bottom of the sliding groove 6 is provided with a guide limit block 29, which matches the guide groove 18 at the bottom of the built-in push-pull component 8, making the movement of the built-in push-pull component 8 more stable and smooth.

[0045] The collar 2 is preferably made of stainless steel. The front surface of the collar 2 has an annular mounting groove 22, and the front end of the annular mounting groove 22 has an annular positioning groove 26. There is also a toothed waterproof ring 23, the main body of which is made of a sealing elastic material. Multiple annular sealing teeth 45 are distributed on its surface, which cooperate with the inner wall of the socket 39 of the socket B to achieve a contact seal. A sealing positioning ring 27 extends inward from the front end along the inner side, and is positioned and fixed in the annular positioning groove 26, thus fixing the toothed waterproof ring 23 to the front of the collar 2, achieving a sealing and waterproof function between the collar 2 and the outer shell 1. Furthermore, the annular fixing groove 30 can be further provided with a third annular sealing groove 43 between the locking mounting hole 10 and the sliding groove 6, lined with a third sealing ring, which can greatly improve the waterproof sealing function.

[0046] The waterproof clamp 3 is provided with a second annular sealing groove 44, and a second sealing ring 21 is fixed in the second annular sealing groove 44 to achieve the waterproof function between the outer shell 1 and the waterproof clamp 3. The bottom of the sliding hole 7 is provided with a mounting groove 28, and the size of the corresponding sealing piece 25 with button mating hole matches it to achieve the waterproof function of the button 9 part.

[0047] In this example, signal connector 38 uses an RJ-45 connector, but other specifications and models of signal connectors can also be used.

[0048] Of course, the socket B that cooperates with this application has a socket 39 for the plug A of this application to be inserted, a plug portion 40 for receiving signal connector 38 in the socket 39, and a locking groove 41 or locking hole on the surface of the plug portion 40 that cooperates with the locking hook 24 of the locking member 11.

[0049] The working principle and operation process are as follows: When the plug A of this application is inserted into the socket B, the locking hook 24 of the locking member 11 will first encounter the plug part 40 of the socket. Since the locking hook 24 usually has a guide slope, it will naturally lift up by rotating the shaft pin 15, and climb to the surface of the plug part 40 until the plug A is completely inserted into the plug part 40 of the socket B to realize the electrical signal connection. Since the connecting part on the locking member 11 is fitted with a spring 16, the spring 16 always applies a backward pushing force, so that the locking member 11 maintains a counterclockwise rotation trend, so that the locking hook 24 extends into the locking groove 41 or locking hole on the plug part 40 of the socket B again to achieve locking again, so that the plug A and the socket B cannot be separated.

[0050] When the user unplugs the plug, the user pushes the button 9 forward along the sliding hole 7 to the closest distance. The button 9 drives the built-in push-pull member 8 to move forward along the sliding groove 6. The push-pull groove 13 at the front end of the connecting part 12 causes the locking member 11 to rotate clockwise along the shaft pin 15 through the push block 33 at one end of the locking member 11. This causes the locking hook 24 of the locking member 11 to disengage from the locking groove 41 or locking hole on the plug part of the socket B, thus unlocking the plug A and allowing it to be pulled out of the socket B normally.

[0051] The technical advantages of this application are:

[0052] 1. The locking component 11 adopts a fully built-in protective design: the locking component 11 is completely stored inside the outer shell 1 of the plug, avoiding external bumps and wear when not plugged in; after the plug and socket are plugged in, the area where the locking component 11 is located forms a closed space, making it difficult for dust and moisture to come into contact with the moving parts of the locking component 11, thus improving the reliability and service life of the locking mechanism.

[0053] 2. Elimination of external full-coverage rubber sleeve: The main body of plug A adopts a zinc alloy shell 1 with a stainless steel collar 2, with only the push-pull button protruding; dynamic sealing is achieved by relying on the internal sealing ring of the shell 1; avoiding the risk of failure caused by the external rubber sleeve being bumped, damaged, aged, or losing elasticity; compared with the shell-equipped solution and the side button structure, the overall shaft diameter is smaller, and the metal shell has a better appearance and texture;

[0054] 3. Quick push-pull locking, balancing sealing and operational efficiency: Unlike threaded tightening structures, unlocking and plugging can be completed by pushing and pulling the button axially, enabling quick one-handed assembly and disassembly, balancing sealing reliability and ease of operation;

[0055] 4. Intermediate connection sealing fault tolerance structure: The button 9, the built-in push-pull part 8, and the locking part 11 are three separate independent parts; the sealing ring is arranged on the outer periphery of the connection part 12 of the built-in push-pull part 8; even if the sealing sheet 25 wears and a small amount of water seeps in, the seepage is blocked on the outside of the built-in push-pull part 8 and will not invade the locking movement pair of the locking part, thus having the fault tolerance capability for sealing failure.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
