Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, specifically a modular connector for rapid assembly. Background Technology

[0002] Cable connectors are a type of connector, often referred to as plugs or sockets in China. Electrical connectors are devices used to connect circuits or equipment. Their main function is to transmit current or signals. They are widely used in aviation, aerospace, defense, communications, industrial automation, and consumer electronics, and are the core components for achieving electrical connections.

[0003] To ensure that operators can easily observe whether the cable core and the inner conductor of the cable connector are aligned with the center when assembling the cable, existing cable connectors are generally not pre-assembled before use, because once assembled, the cable connector cannot be disassembled. However, whether the customer assembles it themselves or the manufacturer assembles it, the cable connector requires professional assembly tools to complete the assembly, which makes the assembly process relatively complicated. Utility Model Content

[0004] The purpose of this invention is to provide a modular connector for rapid assembly, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular connector for rapid assembly includes a housing, an inner housing, an upper bushing, a lower bushing, and an inner conductor. The outer wall of the inner conductor has a retaining ring. The upper and lower bushings fit snugly onto the outer wall of the inner conductor. The inner walls of both the upper and lower bushings have annular grooves for engaging the retaining ring. The inner housing has an annular platform inside, the bottom of which abuts against the tops of the upper and lower bushings. The inner housing also has a clamp located below the upper and lower bushings. The upper bushing has a retaining hole near the clamp. The top of the clamp has an extension block with a latch for engaging the retaining hole. The bottoms of the upper and lower bushings abut against the top of the clamp. Symmetrically arranged spring tabs are located on the side wall of the inner housing away from the clamp. Each of the two spring tabs has a latch. The outer housing has a retaining hole for engaging the latch.

[0007] Furthermore, it also includes a clamping housing, the bottom of which is provided with an annular groove II, and the inner wall of the clamping housing is provided with a retaining ring II that engages with the annular groove II. The bottom of the clamping sleeve is provided with a plurality of elastic elements, which are evenly distributed along the axis of the clamping sleeve. The outer wall of each elastic element is provided with a protrusion, which is located at the bottom of the elastic element. The inner wall of the clamping housing is provided with a top ring that abuts against the protrusion. The top ring presses against the protrusion, causing the bottom of the elastic element to tighten inward.

[0008] Furthermore, the inner housing is provided with a movable hole that communicates with the first card hole. The movable hole has the same shape as the first card hole, and a movable block is slidably connected inside the movable hole.

[0009] Furthermore, the top two sides of the movable block are symmetrically provided with extension portions, and the outer wall of the inner shell is symmetrically provided with limiting grooves. Both limiting grooves are located directly below the two extension portions. The bottom of the two extension portions is provided with limiting posts that are inserted into the corresponding limiting grooves. A certain amount of space is left between the bottom of the limiting post and the bottom of the limiting groove. The limiting post is covered with a return spring. One end of the return spring is fixedly connected to the bottom of the extension portion, and the other end is fixedly connected to the outer wall of the inner shell.

[0010] Furthermore, the first buckle located on the upper bushing side, the second buckle located on the outer shell insertion side, and the top ring located on the clamping side are all provided with guide slopes.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention involves first passing the cable core through the clamp and connecting it to the inner conductor; then, aligning the annular grooves of the upper and lower bushings with the retaining rings on the inner conductor and inserting them to fix the inner conductor between the upper and lower bushings. Next, insert the upper and lower bushings upwards from the bottom of the inner housing until their tops contact the bottom of the annular platform in the inner housing. Then, insert the clamp upwards from the bottom of the inner housing until its top contacts the bottom of the upper and lower bushings, ensuring that the first buckle engages in the first locking hole. Finally, insert the outer shell downwards from the top of the inner housing until the second buckle engages in the second locking hole, thus completing the rapid assembly of the connector. This invention requires no auxiliary tools during assembly, and all components are connected by snap-fit, simplifying the assembly process, greatly improving assembly efficiency, and demonstrating promising application prospects.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-10 ;

[0027] A modular connector for rapid assembly includes a housing 1, an inner housing 2, an upper bushing 3, a lower bushing 4, and an inner conductor 5. The inner conductor 5 is used to connect with a cable core. A retaining ring 51 is provided on the outer wall of the inner conductor 5. The upper bushing 3 and the lower bushing 4 are fitted onto the outer wall of the inner conductor 5. The inner walls of the upper bushing 3 and the lower bushing 4 are each provided with annular grooves 31 for engaging the retaining ring 51, thereby fixing the inner conductor 5 between the upper bushing 3 and the lower bushing 4. An annular platform 20 is provided inside the inner housing 2. The bottom of the annular platform 20 abuts against the top of the upper bushing 3 and the lower bushing 4, thereby limiting the displacement of the upper bushing 3 and the lower bushing 4 along the direction of the annular platform 20. In addition, the inner shell 2 is also provided with a sleeve 6. The sleeve 6 is located below the upper bushing 3 and the lower bushing 4. The upper bushing 3 has a locking hole 32 at one end near the sleeve 6. The top of the sleeve 6 is provided with an extension block 61. The extension block 61 is provided with a buckle 62. The buckle 62 is inserted into the locking hole 32. When the sleeve 6 is inserted into place, the buckle 62 can automatically lock into the locking hole 32, thereby fixing the position of the sleeve 6. At the same time, the top of the sleeve 6 abuts against the bottom of the upper bushing 3 and the lower bushing 4 to prevent the upper bushing 3 and the lower bushing 4 from shifting along the direction of the sleeve 6, thereby fixing the position of the upper bushing 3 and the lower bushing 4. Symmetrical spring tabs 21 are provided on the side wall of the inner housing 2 away from the jacket 6. Each spring tab 21 has a second snap fastener 22 on its outer wall. The outer housing 1 has a second snap hole 11. The second snap fastener 22 engages with the second snap hole 11. When the outer housing 1 is inserted downwards from the top of the inner housing 2, the second snap fastener 22 protrudes from the outer surface of the inner housing 2. Therefore, during insertion, the inner wall of the outer housing 1 will squeeze the second snap fastener 22, causing the spring tabs 21 to bend towards the center. When the outer housing 1 is inserted until the second snap hole 11 and the second snap fastener 22 are aligned, the spring tabs 21 return to their original shape, and the second snap fastener 22 automatically engages with the second snap hole 11, thus completing the fixed installation of the outer housing 1 and the inner housing 2. Preferably, an anti-slip pad is provided on the outer wall of the outer housing 1 to increase the friction for the operator's grip and ensure stability when holding the connector.

[0028] In use, first, the cable core wire is passed through the clamp 6 and connected to the inner conductor 5; then, the annular groove 31 of the upper bushing 3 and the lower bushing 4 is aligned with the retaining ring 51 on the inner conductor 5 and inserted, thereby fixing the inner conductor 5 between the upper bushing 3 and the lower bushing 4. Next, the upper bushing 3 and the lower bushing 4 are inserted upward from the bottom of the inner housing 2 until the top of the upper bushing 3 and the lower bushing 4 contacts the bottom of the annular platform 20 in the inner housing 2. Then, the clamp 6 is inserted upward from the bottom of the inner housing 2 until the top of the clamp 6 contacts the bottom of the upper bushing 3 and the lower bushing 4, and it is ensured that the first buckle 62 is engaged in the first buckle hole 32. Finally, the outer shell 1 is inserted downward from the top of the inner housing 2 until the second buckle 22 is engaged in the second buckle hole 11, thereby completing the rapid assembly of the entire connector. This application does not require any auxiliary tools during the assembly process. All components are connected by snap-fit, the assembly steps are simple, the assembly efficiency is greatly improved, and it has good application prospects.

[0029] In this embodiment, the connector also includes a clamping housing 7. The bottom of the inner housing 2 is provided with an annular groove 23. The inner wall of the clamping housing 7 is provided with a retaining ring 72 that is inserted into the annular groove 23, thereby completing the fixation of the clamping housing 7. The clamping housing 7 is snapped onto the outside of the inner housing 2. During assembly, the cable core wire should be passed through the clamping housing 7 first, and then the cable core wire should be passed through the clamping sleeve 6. The bottom of the clamping sleeve 6 is provided with several elastic elements 63, which are evenly distributed along the axis of the clamping sleeve 6. Each elastic element 63 has a protrusion 64 on its outer wall, and the protrusions 64 are all located at the bottom of the elastic element 63. The inner wall of the clamping housing 7 is provided with a top ring 71 that abuts against the protrusions 64. The top ring 71 presses against the protrusions 64, causing the bottom of the elastic element 63 to tighten inward. When the clamping housing 7 is installed in place, the top ring 71 on its inner wall will contact the protrusions 64 of each elastic element 63 and apply pressure towards the center. Since the elastic element 63 has a certain elastic deformation capacity, under the action of the top ring 71, the bottom of the elastic element 63 will tighten inward, thereby applying a certain preload force to the cable core wire to prevent it from loosening due to vibration or pulling during use and to ensure the stability of use.

[0030] In this embodiment, the inner housing 2 is provided with a movable hole 24 communicating with the locking hole 32. The shape of the movable hole 24 is the same as that of the locking hole 32. A movable block 25 is slidably connected inside the movable hole 24, and the movable block 25 can slide up and down inside the movable hole 24. When it is necessary to check or replace the connection status between the cable core and the inner conductor 5, first pull out the clamping housing 7 directly to release the pre-tightening force of the elastic element 63 on the cable core, and then press down on the movable block 25 so that the movable block 25 pushes the latch 62 on the top of the clamp 6 downward to disengage from the locking hole 32, thereby releasing the locking state of the clamp 6. The clamp 6 can be easily pulled out, which facilitates subsequent inspection and maintenance by operators and greatly improves the efficiency of subsequent maintenance of the connector.

[0031] In this embodiment, the top two sides of the movable block 25 are symmetrically provided with extension portions 26, and the outer wall of the inner shell 2 is symmetrically provided with limiting grooves 29. The two limiting grooves 29 are located directly below the two extension portions 26. The bottom of the two extension portions 26 is provided with limiting posts 27 that are inserted into the corresponding limiting grooves 29. A certain amount of space is left between the bottom of the limiting post 27 and the bottom of the limiting groove 29. The limiting post 27 is covered with a return spring 28. One end of the return spring 28 is fixedly connected to the bottom of the extension portion 26, and the other end is fixedly connected to the outer wall of the inner shell 2. When the operator presses the movable block 25 down, the return spring 28 is compressed by the pressure. When the pressing pressure is released, the return spring 28 pushes the movable block 25 upward to the initial position by its own elastic restoring force, thereby realizing the automatic rebound function of the movable block 25. The setting of the limiting post 27 and the sleeve of the return spring 28 on the outside of the limiting post 27 are mainly used to prevent the return spring 28 from tilting, bending or other adverse deformations during the compression process, reduce the lateral force borne by the spring during operation, avoid stress concentration, and thus extend the service life of the return spring 28.

[0032] In this embodiment, the first buckle 62 located on the side of the upper bushing 3, the second buckle 22 located on the side of the outer shell 1 insertion, and the top ring 71 located on the side of the clamp 6 are all provided with guide slopes. The guide slopes facilitate the smooth sliding of the first buckle 62 and the second buckle 22 into the first buckle hole 32 and the second buckle hole 11, and facilitate the top ring 71 to press the protrusion 64. No manual pressing is required, making the installation simple and convenient.
