[0002] RJ45 plug, also known as RJ45 crystal head, is used for the termination of data cables to achieve the connection and change between equipment and patch panel modules. RJ45 crystal head is required to have good conduction performance; the contact three-pronged spring plate is gold-plated with a thickness of 50μm, meeting the Category 5e transmission standard and conforming to the T568A and T568B line sequence; it has the functions of preventing loosening, plugging and unplugging, and self-locking. RJ45 of computer network is the common name for the standard 8-bit modular interface, among which RJ11 and RJ12 are similar to the RJ45 connector structure, except that RJ12 has 6 connection terminals and RJ11 has 4 connection terminals.

[0003] Since the external dimensions of the RJ11 and RJ12 male ends are the same in width and height, when the female socket that needs to be connected to the RJ11 connector male end is installed on the circuit board, it is easy to mistakenly insert the RJ12 male end into the RJ11 connector female socket when plugging with the outside, and after the wrong insertion, the user cannot directly receive the wrong insertion information by observation. When there are many connector interfaces, they need to be checked one by one, which not only affects the plug-in efficiency of the connector, but also affects the transmission of connector information. Therefore, it is necessary to make further improvements to the existing connector structure. Utility Model Content

[0007] As a preferred solution, the first signal terminals are four in number and arranged in a transverse spacing, and the first signal terminal includes an integrally formed second main body portion, a third elastic contact portion and a second welding portion; the second main body portion is embedded in the insulating body, the third elastic contact portion extends inwardly into the insertion cavity and deforms downward as the external crystal head is inserted; the second welding portion extends backward from the insulating body.

[0030] Please refer to Figures 1 to 4 , which shows the specific structure of a preferred embodiment of the present utility model, including an insulating body 10 , a first signal terminal 20 , a second signal terminal 30 and a connecting member 40 .

[0032] The first signal terminal 20 is embedded in the insulating body 10 and is located in the insertion cavity 101; in this embodiment, the first signal terminal 20 is 4 arranged in a horizontal interval, and the first signal terminal 20 includes an integrally formed second main body 211, a third elastic contact portion 212 and a second welding portion 213; the second main body 211 is embedded in the insulating body 10, the third elastic contact portion 212 extends inwardly into the insertion cavity 101 and deforms downward with the insertion of the external crystal head, thereby achieving contact and conduction with the male terminal; the second welding portion 213 extends backward from the insulating body 10; the rear ends of the third elastic contact portions 212 are all extended inwardly into the corresponding limiting grooves 102, so as to prevent the third elastic contact portions 212 from accidentally touching each other when the third elastic contact portions 212 are deformed downward;

[0033] There are two second signal terminals 30, which are respectively arranged on the left and right sides of the first signal terminal 20. Each second signal terminal 30 includes an integrally formed first main body 31, a first elastic contact portion 32 and a first welding portion 33. The first main body 31 is embedded in the insulating body 10. The first elastic contact portion 32 extends inwardly into the insertion cavity 101 and deforms downwardly as the external crystal plug is inserted. The first welding portion 33 extends backward from the insulating body 10. The first welding portion 33 is used to connect with the external control board.

[0034] The connector 40 is disposed on the insulating body 10 and is located in the insertion cavity 101. The connector 40 includes an integrally formed and connected mounting portion 41 and two second elastic contact portions 42 that are integrally bent upward at both ends of the mounting portion 41. The two second elastic contact portions 42 are respectively located directly below the first elastic contact portion 32 of the two second signal terminals 30.

[0035] The design focus of the utility model is that: it extends into the insertion cavity inwardly through the first elastic contact part and deforms downward as the external crystal head is inserted; and the matching connector includes an integrally formed and connected mounting part and two second elastic contact parts that are integrally bent upward at both ends of the mounting part, and the two second elastic contact parts are respectively located directly below the first elastic contact parts of the two second signal terminals. When the male end of the RJ12 connector is inserted, since the RJ12 male end has 6 connection terminals, the connection terminals on both sides will squeeze the two first elastic parts to deform downward and contact and conduct with the two second elastic contact parts, and cause a short circuit between the two second signal terminals. At this time, the short circuit information of the second signal terminal is detected by the mainboard, and the information of the wrong insertion can be received, and adjustments can be made in time without checking one by one, which greatly improves the efficiency of plugging and ensures the information transmission process between the connectors.
