Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly relates to an industrial waterproof connector. Background Art

[0002] With the continuous development of the economy and the continuous improvement of the technical level, extremely rich material conditions are provided for people, thereby improving people's living standards. Just because of the continuous improvement of people's living standards, the demand for various electronic products is increasing day by day, thus creating a good development platform for the development of electronic products. Among them, in electronic products, connectors can be seen everywhere. This is because the use of connectors will relatively shorten the design cycle of electronic products, save design costs, and facilitate disassembly and maintenance. Therefore, connectors are widely used in electronic products and various electrical equipment.

[0003] In the industrial production environment, as a key component for equipment connection, the performance of the connector directly affects the normal operation of the equipment. There are many problems in the actual use of traditional industrial connectors.

[0004] On the one hand, the waterproof performance is insufficient. It is easy for the connection between the connector plug and the socket to become loose, resulting in the generation of gaps, and liquids can easily penetrate in, which not only affects the normal operation of the connector, but may also cause equipment failures and even safety hazards. On the other hand, during the long-term use of the power cord, the end part is often bent, resulting in cracks at the bent part, shortening the service life of the power cord, increasing the equipment maintenance cost and the risk of downtime. In addition, the connection between the plug and the socket of some connectors is not tight enough. Under the influence of factors such as vibration generated during the operation of industrial equipment, the connection is likely to become loose, resulting in unstable or interrupted signal transmission, affecting the continuity and stability of industrial production.

[0005] Therefore, there is an urgent need for an industrial waterproof connector that can effectively solve the above problems, has excellent waterproof performance, can protect the power cord, and has a firm connection. Summary of the Invention

[0016] Advantages of the present invention:

[0017] (1) Excellent waterproof performance: When the connector socket is matched with the connector plug, the fitting plate of the socket body and the plug body forms the first layer of waterproof protection, and the insertion cavity and the contact head are connected to form the second layer of waterproof protection. The double protection effectively blocks the penetration of liquid; The cover plate is buckled to the right side of the socket body, and its fitting flange and sealing strip further enhance the waterproofness, preventing dust from entering and liquid from seeping in;

[0018] (2) Effectively protect the power cord: Through the coordinated action of the buckle plate, adapter, plug rod, sleeve and return spring of the anti-bending mechanism, when the end of the power cord is bent, the plug rod slides into the sleeve and squeezes the return spring, and the return force of the return spring pushes the plug rod to reset, so that the bent part of the power cord returns to its original state, preventing the power cord from breaking due to long-term bending and extending the service life of the power cord;

[0019] (3) Stable connection effect: In the clamping mechanism, through the cooperation of the locking member, L-shaped connecting rod and clamping rod, the clamping rod is clamped into the buckle. The buckle and the clamping rod are tightly connected and not easily separated due to accidental touch, ensuring that the plug body and the socket body are firmly locked, preventing the plug from loosening and falling off, ensuring the stability of the connection, and further improving the overall waterproof performance;

[0020] (4) Through the coordinated work of the above-mentioned mechanism, it has multiple advantages. In terms of waterproofing, the fitting plate of the socket body and the plug body, the insertion cavity and the contact head form a double waterproof protection, and the fitting flange and the sealing strip of the cover plate further enhance the waterproof performance, effectively blocking liquid and dust; in terms of power cord protection, the anti-bending mechanism uses the cooperation of the buckle plate, the adapter, the insertion rod, the sleeve and the return spring. Through the resilience of the return spring, the bent part of the power cord is reset to prevent it from breaking due to long-term bending and extend its service life; in terms of connection stability, the clamping mechanism is combined with the locking member, the L-shaped connecting rod and the clamping rod, so that the clamping rod is tightly connected to the buckle and is not easily accidentally separated, ensuring that the plug and the socket are firmly locked, which not only ensures stable connection but also further improves the waterproof performance, realizing the efficient unity of waterproofing, protection and stable connection.

Detailed implementation mode

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1-6 As shown, the present invention is an industrial waterproof connector, including a connector socket 1. A connector plug 2 is arranged on the right side of the connector socket 1. An anti-bending mechanism 3 is arranged on the right outer wall of the connector plug 2. The anti-bending mechanism 3 can protect the power cord 204 from being bent for a long time, resulting in rupture at the bent part and affecting the use. A clamping mechanism 4 is arranged on the left side of the connector plug 2. The clamping mechanism 4 is used to clamp the connector plug 2 and the connector socket 1 together, avoiding loosening of the connection between the connector plug 2 and the connector socket 1, reducing the hidden danger of generating gaps, and preventing liquid from penetrating into the gaps;

[0035] The connector socket 1 includes a mounting plate 101 which is used for fixedly installing the socket body 104 so that it can be installed together with the device. The left side inside of the mounting plate 101 is threadedly connected with a fixing plate 102 by bolts. The fixing plate 102 is used for fixing the wiring base 103. The center of the left side of the fixing plate 102 is fixedly connected with the wiring base 103. The wiring base 103 is used for connecting the socket body 104 and the connecting wire inside the device together. The right side of the mounting plate 101 is fixedly connected with the socket body 104. The socket body 104 is used for receiving the plug body 201 so that it can be connected with the connector plug 2 together. The center of the bottom of the socket body 104 is fixedly connected with a flexible connection strip 105. The flexible connection strip 105 is used for fixing the cover plate 106 and connecting the cover plate 106 and the socket body 104 together. The bottom of the flexible connection strip 105 is fixedly connected with the cover plate 106. The cover plate 106 can be buckled to the right side of the socket body 104. When the socket body 104 is not connected to the connector plug 2, it covers the side of the socket body 104 to prevent dust from entering the socket body 104. Inside the right side of the socket body 104 is fixedly connected with a socket cavity 107 which is used for receiving the contact head 203. The left side of the wiring base 103 is connected to the connecting wire inside the device, and the right side of the wiring base 103 is connected to the socket cavity 107.

[0036] In this embodiment, preferably, the right side of the cover plate 106 is processed with a fitting flange, and the outer wall of the fitting flange is sleeved with a sealing strip made of rubber material. The cover plate 106 can be buckled to the right side of the socket body 104 through the fitting flange. After the cover plate 106 is buckled to the right side of the socket body 104, it can seal the right side of the socket body 104 to prevent dust from entering, and through the work of the sealing strip, it can also enhance the waterproof performance of the socket body 104.

[0037] In this embodiment, preferably, the connector plug 2 includes a plug body 201 which can be inserted into the right side inside of the socket body 104. The left side of the plug body 201 is fixedly connected with a fitting plate 202. The fitting plate 202 is used for fixing the contact head 203 and can make the left side of the connector plug 2 more tightly connected to the right side of the socket body 104, enhancing the waterproof performance when the socket body 104 and the plug body 201 work. Inside the left side of the fitting plate 202 is fixedly connected with the contact head 203. The contact head 203 can be fitted into the right side of the socket cavity 107. The right side of the socket body 104 is evenly connected with multiple power lines 204. The plug body 201 is inserted into the right side inside of the socket body 104 through the fitting plate 202. The left side of the contact head 203 is inserted together with the right side of the socket cavity 107, and the right side of the contact head 203 is connected to the multiple power lines 204. Two buckle plates 301 are respectively buckled on the top and bottom of the outer wall of the left side of the multiple power lines 204.

[0038] In this embodiment, preferably, a plurality of slots are evenly formed at the top and bottom of the right outer wall of the plug body 201, and a plurality of clamping plates can be inserted into the slots. A sliding groove and a sliding track are respectively formed at the front and rear of the inner right side of the plug body 201 and at the center of the front surface and the center of the back surface of the right side of the plug body 201. The sliding groove and the sliding track are used to define the movement stroke and movement track of the clamping mechanism 4, and a clamping groove is machined on the right side of the sliding track for clamping the clamping block 4015 in the clamping member.

[0039] In summary, through the mutual cooperation of the connector socket 1 and the connector plug 2, when a waterproof connector is needed, first install the connector socket 1 and the device together through the mounting plate 101, and connect the connecting wire in the device to the socket body 104 through the wiring seat 103, then the installation of the connector socket 1 can be completed. After installing the connector socket 1, connect the power cord 204 or another connecting wire that needs to be connected to the device to the right side of the plug body 201 in the connector plug 2, and then insert the plug body 201 into the right side of the socket body 104. After connecting the plug body 201 and the socket body 104 together, the outer wall of the socket body 104 can form a first layer of waterproof protection through the cooperation with the fitting plate 202, and after the insertion cavity 107 and the contact head 203 are connected together, another layer of waterproof protection can be formed, thus providing double insurance and further improving the waterproof performance of the connector socket 1 and the connector plug 2.

[0040] Embodiment 2

[0041] Please refer to Figures 1-4 and Figure 7As shown in the figure, on the basis of the first embodiment, the anti-bending mechanism 3 includes two buckle plates 301. The buckle plates 301 are used to fix the adapter 302 and can be buckled to the top and bottom outer walls of the power cord 204. A plurality of adapters 302 are fixedly connected to the top and bottom of the two buckle plates 301 at equal intervals. The adapter 302 is used to support the plug rod 303. The inner side of the top of each adapter 302 is rotatably connected to a plug rod 303. The plug rod 303 can slide inside the sleeve 304. Thus, through the mutual cooperation of the plug rod 303 and the sleeve 304, the connection length of the sleeve 304 and the plug rod 303 can be adjusted according to the bending degree of the power cord 204. The outer wall of each plug rod 303 is slidably connected to a sleeve 304. The sleeve 304 is used to support the plug rod 303 and can fix the support head 306. A return spring 305 is sleeved on the outer walls of each sleeve 304 and the plug rod 303. The return spring 305 is used to reset the sleeve 304 and the plug rod 303. When the power cord 204 is bent, it will change the support length of the sleeve 304 and the plug rod 303, so that the return spring 305 deforms. Through the resilience generated when the return spring 305 contracts under force, the sleeve 304 and the plug rod 303 can be reset. Thus, through the mutual cooperation of the sleeve 304, the plug rod 303 and the return spring 305, the bending point at the end of the power cord 204 can be reset, avoiding the breakage of the power cord 204 at the end due to being bent for a long time. And the ends of the return spring 305 are fixedly connected to the left outer wall of the sleeve 304 and the right outer wall of the plug rod 303 respectively. A support head 306 is fixedly connected to the left side of each sleeve 304. The support head 306 is used to fix the plug board 307. The left sides of a plurality of support heads 306 are fixedly connected to a plug board 307. The plug board 307 is used to install the support head 306 and install it together with the plug body 201. Fixed buckles 308 are fixedly connected to the left and right sides of the front and back surfaces of the two buckle plates 301. Through the mutual cooperation with the locking belt 309, the fixed buckles 308 can lock and connect the buckle plates 301 at the top and bottom together, so that the buckle plates 301 are more tightly connected to the end of the power cord 204, avoiding the detachment of the buckle plates 301 from the outer wall of the connecting wire. The locking belt 309 is sleeved on the outer walls of the plurality of fixed buckles 308 at the bottom. A clamping head 310 is fixedly connected to the middle position of the outer wall of each locking belt 309.

[0042] In this embodiment, preferably, a plurality of card holes are evenly formed at the top position of each locking belt 309. The top of each clamping head 310 is processed with a ball head whose outer diameter is slightly larger than the inner diameter of the card hole. The top of the locking belt 309 can penetrate out from the inside of the fixed buckle 308 at the top, and after being bent, it fits back to the middle position of the outer wall of the locking belt 309 and can clamp the clamping head 310 into the card hole formed at the top of the locking belt 309.

[0043] In summary, after connecting the power cord 204 and the connector plug 2 together, insert the insertion plate 307 in the anti-bending mechanism 3 into the inside of the slots opened at the top and bottom of the outer wall of the plug body 201. Through the mutual cooperation of the insertion plate 307 and the opened slots, the anti-bending mechanism 3 can be installed. After fixing the insertion plate 307, fasten the two buckle plates 301 to the top and bottom of the outer wall at the end of the power cord 204 respectively. After fastening both buckle plates 301, pass the top end of the locking belt 309 through the inside of the fixing buckle 308 at the top, and then pull the top end of the locking belt 309 downward, so as to lock and connect the two buckle plates 301 together through the locking belt 309. And after adjusting the tightness between the two buckle plates 301, snap the card hole opened at the top end of the locking belt 309 onto the outer wall of the card head 310, so as to fix the adjusted locking belt 309. Through the operation of the locking belt 309, the buckle plate 301 can be tightly connected to the end of the power cord 204. When the end of the power cord 204 is bent, the bent position will drive the corresponding buckle plate 301 to shift together, so that the insertion rod 303 can slide into the inside of the sleeve 304. When the support length between the sleeve 304 and the insertion rod 303 changes, it will simultaneously squeeze the return spring 305, causing the return spring 305 to generate elastic deformation. Thus, the return spring 305 generates a return force when it is compressed and shrunk to reset the insertion rod 303, and the bent part of the power cord 204 is reset by the reset insertion rod 303, avoiding the connection line from breaking due to the long-term bending of the end of the power cord 204, thereby improving the service life of the power cord 204 and enhancing the protection effect on the power cord 204.

[0044] Embodiment III

[0045] Please refer to Figures 1-4 and Figures 8-10As shown, based on the first and second embodiments, the clamping mechanism 4 includes two symmetrically arranged locking members 401. The locking members 401 are used to drive the L-shaped connecting rod 403 to move, and when the L-shaped connecting rod 403 does not need to move, it clamps the L-shaped connecting rod 403 to prevent the clamping rod 404 from shifting driven by the L-shaped connecting rod 403. The tightness of the clamping of the clamping rod 404 by the snap 405 is ensured. Two spring struts 402 are arranged on the left side of each of the two locking members 401. The spring struts 402 are used to reset the locking members 401. L-shaped connecting rods 403 are arranged at the top and bottom of the back of the front locking member 401 and at the top and bottom of the front surface of the rear locking member 401. The L-shaped connecting rods 403 are used to connect the locking members 401 and the clamping rods 404 together. The other ends of the plurality of L-shaped connecting rods 403 are fixedly connected with clamping rods 404. Through the mutual cooperation of the clamping rods 404 and the snaps 405, the connection between the socket body 104 and the plug body 201 can be made more tight, and it can prevent the snap 405 from being accidentally touched and causing the cancellation of the clamping between the snap 405 and the clamping rod 404. The two clamping rods 404 at the top and the two clamping rods 404 at the bottom among the plurality of clamping rods 404 are symmetric with each other. The front outer walls of the two clamping rods 404 at the front end and the rear outer walls of the two clamping rods 404 at the rear end are respectively clamped with snaps 405. A handle 406 is fixedly connected to the center of the front surface of the front snap 405 and the center of the back of the rear snap 405 among the two snaps 405. The plurality of L-shaped connecting rods 403 and the clamping rods 404 are all slidably connected inside the chutes opened at the front end and the rear end of the right side inside the plug body 201. The left sides of the two snaps 405 are rotatably connected to the outer wall of the socket body 104 through pins. The left sides of the two spring struts 402 at the front end and the left sides of the two spring struts 402 at the rear end are respectively fixedly connected to the left inner walls of the chutes opened at the center of the front surface and the center of the back of the right side of the plug body 201.

[0046] In this embodiment, preferably, arched grooves are provided at the middle right positions on the front surface of the front snap 405 and at the middle right positions on the back of the rear snap 405 among the two snaps 405. By providing the arched grooves, a moving space for the locking member 401 can be reserved. Semi-circular grooves with the same outer diameter specification as the clamping rod 404 are provided at the positions where the two snaps 405 are clamped with the clamping rod 404. By providing the semi-circular grooves on the snaps 405, the clamping rod 404 can be fitted into the semi-circular grooves, preventing the snap 405 from directly separating from the clamping rod 404 when the snap 405 is accidentally touched, which affects the tightness of the connection between the snap 405 and the clamping rod 404.

[0047] In this embodiment, preferably, the two locking members 401 are symmetric to each other with the central axis of the plug body 201 as the axis. Among them, the locking member 401 located at the front end includes a groove block 4011, and the groove block 4011 is used to support the button 4012, so that the button 4012 can slide inside it and can drive the L-shaped connecting rod 403 to move. The button 4012 is slidably connected to the inside of the front surface of the groove block 4011. The button 4012 is used to drive the first rack 4013 to move. The top and bottom inner walls of the button 4012 are fixedly connected with the first rack 4013. The first rack 4013 is used to drive the gear 4014 to rotate. The bottom rear end of the first rack 4013 located at the top and the top front end of the first rack 4013 located at the bottom among the two first racks 4013 are both meshed with the gear 4014. The gear 4014 is used to drive the second rack 4016 to move. A latch 4015 is slidably connected to the inside of the back of the groove block 4011. The latch 4015 is used to latch the groove block 4011 to prevent the overall displacement of the locking member 401 when the groove block 4011 is accidentally touched. The top and bottom of the back of the latch 4015 are fixedly connected with the second rack 4016. The second rack 4016 is used to drive the latch 4015 to move, so that the buckle 405 can be retracted into the groove block 4011, thereby canceling the latching between the latch 4015 and the card slot, enabling the groove block 4011 to slide inside the slideway. The top front end of the second rack 4016 located at the top and the bottom front end of the second rack 4016 located at the bottom are respectively meshed with the bottom end of the outer wall of the gear 4014 located at the top and the top end of the outer wall of the gear 4014 located at the bottom. Both of the two gears 4014 are rotatably connected to the left and right sides inside the front surface of the groove block 4011 through pins. The groove block 4011 located at the front end and the groove block 4011 located at the rear end among the two groove blocks 4011 are respectively slidably connected to the inside of the slideways opened at the center of the front surface on the right side and the center of the back of the plug body 201, and the latch 4015 can be latched in the card slot. The right sides of the plurality of spring struts 402 are all slidably connected to the inside of the groove block 4011.

[0048] In summary, after the socket body 104 and the plug body 201 are plugged together, the button 4012 in the locking member 401 is pressed into the inside of the groove block 4011. When the button 4012 slides into the inside of the groove block 4011, it will synchronously drive the first rack 4013 to shift, thereby driving the gear 4014 to rotate through the first rack 4013. While the gear 4014 is rotating, it can drive the second rack 4016 to slide towards the position of the button 4012, thereby driving the latch 4015 to contract into the inside of the groove block 4011 through the second rack 4016, and the engagement between the latch 4015 and the card slot can be cancelled, enabling the groove block 4011 to slide inside the slideway. Then, the groove block 4011 is slid to the left side of the slideway, and the L-shaped connecting rod 403 is driven by the groove block 4011 to slide to the left side inside the chute synchronously. When the L-shaped connecting rod 403 moves, it will drive the latch rod 404 to also generate a displacement. At this time, the buckle 405 is pulled to the right side, so that the inner wall of the buckle 405 can fit against the outer wall of the socket body 104. Then, the pressing of the button 4012 is cancelled. Through the operation of the spring strut 402, the groove block 4011 can be reset. And after the groove block 4011 returns to its original position, the small spring between the button 4012 and the latch 4015 will reset the latch 4015 and the button 4012, so that the latch 4015 is re-engaged into the inside of the card slot. And during the reset process of the groove block 4011, the L-shaped connecting rod 403 and the latch rod 404 will be reset together, so that the latch rod 404 is engaged into the semi-circular groove opened inside the buckle 405. Through the cooperative work of the buckle 405 and the latch rod 404, the plug body 201 and the socket body 104 can be locked together, preventing the plug body 201 from loosening and falling off from the side of the socket body 104, and enabling the connection between the socket body 104 and the plug body 201 to be closer, further improving its waterproof performance. Through the mutual cooperation of the locking member 401, the L-shaped connecting rod 403 and the latch rod 404, the latch rod 404 can be engaged into the inside of the buckle 405, preventing accidental contact with the buckle 405 and thus causing it to fall off from the outer wall of the latch rod 404, affecting the locking effect.

[0049] Embodiment Four

[0050] Please refer to Figures 1-10 As shown, by combining Embodiment One, Embodiment Two and Embodiment Three, this embodiment is obtained. This industrial waterproof connector mainly relies on the collaborative work of the connector socket 1, the connector plug 2, the anti-bending mechanism 3 and the clamping mechanism 4 to achieve the functions of waterproofing, stable connection and protection of the power cord 204.

[0051] In the installation process, first fix the connector socket 1 to the device through the mounting plate 101. The device connecting wire is connected to the socket body 104 through the terminal block 103 to complete the installation of the socket. Then connect the power cord 204 or other connecting wires to the right side of the plug body 201 of the connector plug 2, and then insert the plug body 201 into the right side of the socket body 104. At this time, the fitting plate 202 of the socket body 104 and the plug body 201 cooperate to form the first layer of waterproof protection, and the insertion cavity 107 is connected to the contact head 203 to form the second layer of waterproof protection. The double protection significantly improves the waterproof performance.

[0052] The operation of the anti-bending mechanism 3 is designed to protect the power cord 204. Insert the insertion plate 307 of the anti-bending mechanism 3 into the slot on the right outer wall of the plug body 201. The two buckling plates 301 are buckled on the top and bottom of the end of the power cord 204. Pass the locking belt 309 through the fixing buckle 308 and snap the clamping head 310 into the clamping hole to make the buckling plate 301 tightly connected to the power cord 204. When the end of the power cord 204 is bent, it drives the buckling plate 301 to shift, and the insertion rod 303 slides into the sleeve 304 to squeeze the return spring 305. The return spring force generated by the return spring 305 pushes the insertion rod 303 to reset, thereby restoring the bent part of the power cord 204 to its original state, effectively preventing the power cord 204 from breaking due to long-term bending and extending its service life.

[0053] The clamping mechanism 4 is responsible for ensuring the firm connection between the plug and the socket. After inserting the plug body 201 into the socket body 104, press the button 4012 of the locking member 401. The button 4012 drives the first rack 4013 to move, driving the gear 4014 to rotate, and then the second rack 4016 drives the clamping block 4015 to contract, releasing the clamping connection between the clamping block 4015 and the clamping groove. The groove block 4011 can slide in the slideway. At this time, slide the groove block 4011 to the left, driving the L-shaped connecting rod and the clamping rod 404 to move. Then pull the buckle 405 to fit the outer wall of the socket body 104. After releasing the button 4012, the spring strut 402 pushes the groove block 4011 to reset, and the clamping block 4015 is reinserted into the clamping groove, and the clamping rod 404 is inserted into the semi-circular groove of the buckle 405 to achieve the firm locking of the plug body 201 and the socket body 104. This not only prevents the plug from loosening and falling off, but also further enhances the waterproof performance. At the same time, the special structural design of the buckle 405 avoids the separation of the buckle 405 and the clamping rod 404 due to accidental touch, ensuring the locking effect.

[0054] The above has described a specific embodiment of the present invention in detail, but the described content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the application of the present invention.
