It is suitable for high-frequency and high-speed applications and ensures that the transmitted signals are not distorted.

[0003] Existing electrical connector plugs and sockets use structural accessories such as retaining rings, positioning keys, and guide pins, along with installation accessories such as screws and nuts, for assembly. When there are large deviations in position and parallelism between the electrical connectors, the guide accessories may interfere with the mating end accessories during the auxiliary guiding process due to excessive length, preventing rapid mating. Therefore, to address the above problems, an electrical connector with a floating guide buckle locking mechanism is proposed. Summary of the Invention

[0029] Please see Figure 1-9 The present invention provides a technical solution:

[0030] An electrical connector with a floating guide latch locking mechanism includes a plug connector 1 and a socket connector 2 with a floating guide latch locking mechanism. The plug connector 1 includes a plug base 11, a first bent pin 12, a second bent pin 13, and a guide plug accessory 14. The first bent pin 12 and the second bent pin 13 are installed inside the plug base 11. In the above process, a special tooling is used to press the first bent pin 12 and the second bent pin 13 into place. The plug base 11 has symmetrically distributed guides on its left and right sides. The plug accessory 14 and the socket connector 2 include a socket base 21, a first socket piece 22, a second socket piece 23, and a floating snap-locking socket accessory 24. The first socket piece 22 and the second socket piece 23 are installed inside the socket base 21. In the above process, a special tool is used to press the first socket piece 22 and the second socket piece 23 into the socket base 21. During the pressing process, it is necessary to ensure that the welding plates are back to back. The floating snap-locking socket accessories 24 are symmetrically distributed on the left and right sides of the socket base 21.

[0031] The guide plug accessory 14 includes an accessory guide cylinder 141, a mounting pin 142, a mounting pin nut 143, and a hexagonal nut 144. The accessory guide cylinder 141 is inserted into a through hole inside the plug base 11. The mounting pin 142 is placed on the top of the plug base 11 and on the outer side above the accessory guide cylinder 141. The mounting pin nut 143 inside the mounting pin 142 is detachably connected to the outer side above the accessory guide cylinder 141. One end of the mounting pin 142 is detachably connected to the hexagonal nut 144 via a threaded structure. This configuration forms an assembled guide plug accessory. Component 14, the floating snap-locking socket accessory 24 and the guide plug accessory 14 are assembled together. The floating snap-locking socket accessory 24 includes a positioning barrel 241, a screw sleeve 242, a compression spring 243, and a locking rod 244. The positioning barrel 241 is inserted into a through hole inside the socket base 21. The screw sleeve 242 is threaded onto the outer side of the upper part of the positioning barrel 241. The compression spring 243 is placed inside the screw sleeve 242. The locking rod 244 is inserted into the positioning barrel 241. Through the above arrangement, the core component of the floating snap-locking socket accessory 24 is formed. Above the locking rod 244... The outer side and the inside of the knob 245 are slotted for insertion. Rivets 246 are installed in the through holes inside the knob 245 and the locking rod 244. This arrangement ensures that the rivets 246 can pass smoothly through when assembling the knob 245 and the locking rod 244. Finally, a special rivet tool is used to rivet and fix the rivets 246, forming the socket connector 2. The screw sleeve 242, the compression spring 243, and the upper rod of the locking rod 244 are arranged vertically and coaxially. This arrangement forms the main structure of the floating snap-locking socket accessory 24, which is easy to assemble and install. The first insertion hole 2... The first bent pin 12 is inserted into the interior of the second insertion part 23 and the second bent pin 13 are inserted into the interior of the second insertion part 244. Through the above arrangement, an electrical connection insertion assembly structure is formed. A connecting block that limits the bottom of the positioning barrel 241 is provided on the outer side of the upper rod of the locking rod 244. A protrusion that can elastically retract inward is provided on the outer side of the lower rod of the locking rod 244. A slot is provided on the outer side of the accessory guide cylinder 141 and is locked with the protrusion by a snap-fit. Through the above arrangement, the elastic force of the compression spring 243 is continuously applied to the protrusion through the locking rod 244, generating a continuous and adaptive locking force.

[0032] Workflow: This invention provides an electrical connector with a floating guide latch locking mechanism. The operator holds the plug connector 1 and tentatively aligns the bottom openings of the accessory guide cylinders 141 on both sides of the socket connector 2 with the locking rods 244 of the floating latch locking socket accessory 24 on both sides. Because there are certain assembly gaps between the accessory guide cylinders 141 and the plug base 11, and between the positioning cylinder 241 and the socket base 21, a certain floating installation space is formed. This allows for slight axial offset or angular deviation during initial docking. The locking rods 244 slide into the positioning cylinder 241, ensuring that the first bent pin 12 is basically aligned with the first socket 22, and the second bent pin 13 is basically aligned with the second socket 23, achieving coarse positioning. During this process, the protrusion on the outer side of the lower part of the locking rod 244 is in an inward elastic retraction state. When the locking rod 244 is pushed to its final position inside the accessory guide cylinder 141, the inward elastic retraction protrusion on the outer side of the lower part of the locking rod 244 will continuously abut against the inner wall of the accessory guide cylinder 141. Manually rotating the knob 245 causes the knob 245, the rivet 246, and the locking rod 244 to rotate axially synchronously. Once the protrusion on the locking rod 244 reaches the specially opened slot on the outer side of the accessory guide cylinder 141, under the continuous downward elastic force of the compression spring 243, the entire locking rod 244 is pressed down, and the protrusion quickly pops out and gets stuck in the slot. During the above process, the connecting block on the outer side of the upper part of the locking rod 244 and the positioning cylinder 24 1. A bottom limit is formed to prevent excessive movement. In the locked state, the elastic force of the compression spring 243 acts continuously on the protrusion through the locking rod 244, generating a continuous and adaptive locking force, improving the continuous tightness of the connection. When the plug connector 1 and the socket connector 2 are fully inserted, one end of the mounting pin 142 is threaded with a hexagonal nut 144, so that the outer hexagonal shape of the hexagonal nut 144 will fit tightly with the slot or flat groove opened on the lower shell of the socket base 21, forming an anti-rotation effect between the plug connector 1 and the socket connector 2. The design of the above-mentioned slot or flat groove and the matching structure of the hexagonal nut 144 are common means of anti-rotation treatment for existing electrical connectors, which will not be described in detail in this article. The entire insertion process reflects the " The precise and reliable logic of "first guiding the floating, then inserting, and finally locking" makes the insertion scheme stable and reliable. Compared with similar products with the same number of cores, this invention not only has floating guidance, locking, and anti-misinsertion functions, but also changes the traditional threaded locking structure. Through the staggered distribution of the first bent pin 12, the second bent pin 13, and the corresponding first socket 22 and second socket 23, it provides anti-misinsertion function. The floating locking socket accessory 24 provides guiding and positioning function, and the locking process is achieved by rotating the knob 245. This reduces the positional and parallel requirements of the electrical connector, reduces the risk of misinsertion during product mating, greatly increases the service life of the contacts, and makes it more convenient for customers to use the product.
