Abstract

Technical Field
[0001] This invention relates to the field of electrical connector technology, specifically to a connector with guiding, anti-misinsertion, and self-locking functions. Background Technology
[0002] An electrical connector is an electromechanical device that mechanically connects two or more electrical conductors. It is widely used in various electronic devices and systems. An electrical connector usually consists of a plug (male end) and a socket (female end). Both the plug and the socket are composed of insulators and contacts. Through the cooperation of the contacts of the plug and the socket, a separable circuit connection is formed, which can ensure that current or signals can be transmitted smoothly.
[0003] Some existing electrical connectors have several problems during use: First, they lack guiding and anti-mis-mating structures, which may cause angle deviations or mis-mating during insertion, making it impossible to achieve fast and accurate insertion. Second, they lack self-locking structures, which may cause poor contact due to equipment vibration after insertion, resulting in unstable circuit connections between devices. Therefore, a connector with guiding, anti-mis-mating, and self-locking functions is proposed to address these issues. Summary of the Invention

The connector socket assembly 2 includes a second guide seat 21 that fits against the lower side of the first guide seat 11. A second limiting seat 22 is fixedly connected to the lower end face of the second guide seat 21. A second self-locking protrusion 23 is fixedly connected to the lower rear end of the second limiting seat 22. An anti-misinsertion protrusion 24 is fixedly connected to the lower front end of the second limiting seat 22. A second terminal 26 is provided in the circular groove of the second limiting seat 22. A spring-loaded insertion hole 27 located in the second limiting seat 22 is fixedly connected to the rear side of the second terminal 26. All pins 17 are inserted into the spring-loaded insertion hole 27. A second power transmission line 28 is fixedly connected to the front side of the second terminal 26.
[0023] A first potting compound 15 is filled between the first terminal 16 and the first limiting seat 12. The outer side of the first potting compound 15 is bonded to the first limiting seat 12, and the inner side of the first potting compound 15 is bonded to the first terminal 16. A second potting compound 25 is filled between the second terminal 26 and the second limiting seat 22. The outer side of the second potting compound 25 is bonded to the second limiting seat 22, and the inner side of the second potting compound 25 is bonded to the second terminal 26. The first terminal 16 and the second terminal 26 can be fixed by the first potting compound 15 and the second potting compound 25, respectively. A strip-shaped groove is formed on the lower end face of the first guide seat 11, and a strip matching the first guide seat 11 is formed on the upper end face of the second guide seat 21. The first self-locking protrusion 24 is a shaped protrusion that guides the connector socket assembly 2 through the cooperation of the second guide seat 21 and the first guide seat 11. The lower end face of the anti-misinsertion protrusion 24 is aligned with the lower end face of the first limiting seat 12, and the rear side of the anti-misinsertion protrusion 24 is in contact with the front side of the first limiting seat 12.

The cooperation of the second self-locking protrusion 23 and the first self-locking protrusion 13 can prevent the spring socket 27 and the pin 17 from making poor contact or accidentally falling off.
[0024] Workflow: Before use, electrically connect the first power transmission line 18 and the first terminal 16 and wrap them with insulating tape; electrically connect the second power transmission line 28 and the second terminal 26 and wrap them with insulating tape. Fix the first guide seat 11 in the appropriate position using the mounting block 14. The pin 17 and the spring socket 27 of this device are matched. The first guide seat 11 and the second guide seat 21 of this device have various models. The width and height of the strip groove opened in the first guide seat 11 are different in different models. The width and height of the second guide seat 21 are different in different models. The guide seat 11 has a matching strip-shaped protrusion.

The second guide seat 21, second limiting seat 22, second self-locking protrusion 23, and anti-misinsertion protrusion 24 of this device are integrally molded from insulating material. When using this device, the operator can pick up the connector socket assembly 2 and insert it into the connector plug assembly 1, so that the pin 17, which is fixed by the first limiting seat 12 and the first potting compound 15, is inserted into the part fixed by the second limiting seat 22 and the first potting compound 15. The second potting compound 25 is fixed inside the spring socket 27. This device, through the anti-misinsertion protrusion 24, clearly identifies the placement of the connector socket assembly 2. The cooperation of the second guide seat 21 and the first guide seat 11 provides guidance, preventing misinsertion of connector socket assemblies 2 and connector plug assemblies 1 of different models. This achieves fast and accurate insertion, avoiding equipment contact failure caused by insertion misalignment and equipment damage caused by misinsertion, reducing contact wear, and improving insertion and removal life. Simultaneously, the second self-locking protrusion 23 and the first self-locking protrusion 13... The fit can prevent the relative displacement of the second limit seat 22 and the first limit seat 12 due to equipment vibration, and avoid poor contact or accidental detachment of the spring socket 27 and the pin 17. At the same time, the unique structural features of the spring socket 27 give it good contact performance and vibration and shock resistance, effectively improving the reliability and stability of the circuit connection between devices. This connector has the advantages of guiding, preventing mis-insertion, self-locking, small size, vibration resistance and shock resistance. It can effectively improve operating efficiency, can be used in space-constrained situations, is easy to assemble, and is conducive to cost control.
