[0002] A connector is a device that connects two active devices. It is an electronic component that transmits and exchanges current or optical signals between electronic system devices. As a node, it transmits current or optical signals between devices, components, equipment, and subsystems, either independently or together with cables, while maintaining signal distortion and energy loss between systems. It is a fundamental component necessary for the connection of the entire complete system.

[0003] Connectors typically consist of a plug and a socket that are compatible and conduct electricity to each other.

[0004] Currently, some plugs and sockets are connected in a way that only the male terminal of the plug is inserted into the female terminal of the socket, while the other parts of the plug are not connected to the socket. In this case, if the male terminal on the plug and the female terminal on the socket cannot be aligned, it will be difficult to achieve mating, which will affect the normal use of the connector and may even damage the male and female terminals, affecting the service life of the entire connector.

[0005] In particular, pin header or pin insert connectors may have the above-mentioned problems. For example, a dual-pin header connector disclosed in Chinese utility model patent CN221632923U has the above-mentioned problems.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic guide stabilizing connector.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The automatic guide stable connector includes: a plug, which includes an insulator and a plurality of male terminals fixed in the insulator, the first contact portion of the male terminal protruding beyond the lower end surface of the insulator; a socket, which includes an insulating base and a plurality of female terminals fixed in the insulating base, the guide groove of the female terminal being exposed on the upper end surface of the insulating base and used for mating and conducting with the first contact portion of the male terminal; both ends of the insulator are provided with downwardly protruding male end guide posts, the lower end of the male end guide posts protruding beyond the lower end of the first contact portion; both ends of the insulating base are provided with female end guide posts, the upper end of the female end guide posts being provided with guide grooves that mate with the male end guide posts, the opening of the guide grooves being exposed on the upper end surface of the insulating base.

[0009] Furthermore, in the above technical solution, both the male guide post and the female guide post are metal parts. The male guide post and the insulator are integrally formed by in-mold injection molding; the female guide post and the insulating seat are integrally formed by in-mold injection molding.

[0010] Furthermore, in the above technical solution, a first annular positioning groove is provided on the outer periphery of the middle part of the male end guide post, and the first positioning protrusion of the insulator is embedded in the first annular positioning groove; a second annular positioning groove is provided on the outer periphery of the middle part of the female end guide post, and the second positioning protrusion of the insulating seat is embedded in the second annular positioning groove.

[0011] Furthermore, in the above technical solution, the upper end face of the female end guide post is flush with the upper end face of the insulating base, and the lower end of the female end guide post extends beyond the lower end face of the insulating base and protrudes beyond the solder foot of the female terminal.

[0012] Furthermore, in the above technical solution, the female end guide post is provided with a first guide surface at the upper opening of the guide groove; the male end guide post is provided with an arc-shaped guide surface at its lower end.

[0013] Furthermore, in the above technical solution, a third annular positioning groove is provided on the outer surface of the male terminal; the male terminal and the insulator are integrally formed by in-mold injection molding, and the third positioning protrusion formed in the insulator is embedded in the third annular positioning groove.

[0014] Furthermore, in the above technical solution, a fourth annular positioning groove is provided on the outer surface of the female terminal; the female terminal and the insulating seat are fixed together by in-mold injection molding, and the fourth positioning protrusion formed in the insulating seat is embedded in the fourth annular positioning groove.

[0015] Furthermore, in the above technical solution, the upper end of the male terminal is provided with a wiring groove that is connected and welded to the metal core of the conductor, and the upper end of the male terminal is also provided with a beveled surface that penetrates the wiring groove. The upper periphery of the male terminal is provided with a through hole for preventing poor cold soldering.

[0016] Furthermore, in the above technical solution, the female terminal is provided with an inner sleeve in the guide groove to improve conductivity and clamping force. The inner sleeve has a through hole for the first contact portion of the male terminal to pass through, and the lower end of the inner sleeve has a guide arm for elastic contact with the outer surface of the first contact portion. The end of the guide arm is a free end.

[0017] Furthermore, in the above technical solution, the inner sleeve includes a non-closed cylindrical body and at least two guide arms formed by bending and extending along the lower end of the cylindrical body. The cylindrical body has the perforation. After being compressed from the outside to the inside, the cylindrical body is inserted into the guide groove, and the elastic force formed by the cylindrical body from the inside to the outside is engaged and positioned with the inner wall of the guide groove.

[0018] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: Since the plug and socket are respectively provided with corresponding male and female guide posts, and the lower end of the male guide post of the plug protrudes beyond the lower end of the first contact portion, when the plug is inserted into the socket, the lower end of the male guide post will first align with the guide groove of the female guide post in the socket, ensuring the symmetrical position of the plug and socket. After the male guide post has inserted a short distance into the guide groove, the first contact portion of the male terminal in the plug will then insert into the guide groove of the female terminal. As the male guide post and the first contact portion of the male terminal continue to insert, the plug and socket achieve a stable connection. In the above process, due to the prior alignment of the guide grooves of the male and female guide posts, the insertion of the plug and socket is automatically guided, ensuring precise alignment of the male terminal of the plug and the female terminal of the socket, guaranteeing smooth insertion, enabling rapid insertion, improving insertion efficiency, and avoiding damage to the male and female terminals, thus ensuring the service life of the entire connector.

[0030] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0031] See Figure 1-11 As shown, an automatic guide stabilizing connector includes a plug 100 and a socket 400 adapted to the plug 100.

[0032] In this embodiment, the plug 100 is connected to a wire, and the socket 400 is fixedly mounted on the PCB board.

[0033] The plug 100 includes an insulator 1 and a plurality of male terminals 2 fixed in the insulator 1. The first contact portion 21 of the male terminal 2 protrudes from the lower end face of the insulator 1 and is used to connect and communicate with the socket 400. Correspondingly, the socket 400 includes an insulating base 4 and a plurality of female terminals 5 fixed in the insulating base 4. The guide groove 51 of the female terminal 5 is exposed on the upper end face of the insulating base 4 and is used to connect and communicate with the first contact portion 21 of the male terminal 2. When the plug 100 is plugged into the socket 400, only the first contact portion 21 of the male terminal 2 of the plug 100 is inserted into the guide groove 51 of the female terminal 5, thereby achieving communication. The insulator 1 of the plug 100 and the insulating base 4 of the socket 400 are not plugged in, but only in surface contact, or even not in contact at all.

[0034] The present invention makes the following improvements: both ends of the insulator 1 are provided with downwardly protruding male end guide posts 3, the lower end of which protrudes beyond the lower end of the first contact portion 21; both ends of the insulating base 4 are provided with female end guide posts 6, the upper end of which is provided with a guide groove 61 that connects with the male end guide post 3, and the opening of the guide groove 61 is exposed on the upper surface of the insulating base 4. Because the lower end of the male guide post 3 of the plug 100 protrudes beyond the lower end of the first contact portion 21, when the plug 100 is inserted into the socket 400, the lower end of the male guide post 3 will first align with the guide groove 61 of the female guide post 6 in the socket 400, ensuring that the plug 100 and the socket 400 are in the correct symmetrical position. After the male guide post 3 has been inserted a short distance into the guide groove 61, the first contact portion 21 of the male terminal 2 in the plug 100 will be inserted into the guide groove 51 of the female terminal 5. As the male guide post 3 and the first contact portion 21 of the male terminal 2 continue to be inserted, the plug 100 and the socket 400 will be stably connected. In the above process, due to the prior docking of the guide grooves 61 of the male guide post 3 and the female guide post 6, the plug 100 and the socket 400 are automatically guided, so that the male terminal 2 of the plug 100 and the female terminal 5 of the socket 400 are accurately aligned, ensuring that the plug 100 and the socket 400 are successfully connected and forming a quick connection, improving the connection efficiency. At the same time, it can also avoid damage to the male and female terminals, ensuring the service life of the entire connector.

[0035] The male guide post 3 and the female guide post 6 are both metal parts, which gives them good wear resistance and allows them to be used for a long time. They also have good high temperature resistance. In addition, the male guide post 3 and the female guide post 6 can also be used for grounding to meet different usage requirements.

[0036] The female guide post 6 has a first guide surface 611 at the upper opening of the guide groove 61; the male guide post 3 has an arc-shaped guide surface 32 at its lower end, so that when the lower end of the male guide post 3 contacts the guide groove 61 of the female guide post 6, the arc-shaped guide surface 32 contacts the first guide surface 611 first, which plays a guiding role, ensuring that the lower end of the male guide post 3 can quickly enter the guide groove 61. At the same time, it also has a certain tolerance effect, that is, the lower end of the male guide post 3 is slightly off from the center of the guide groove 61, but as the arc-shaped guide surface 32 contacts the first guide surface 611 first, it can guide the lower end of the male guide post 3 to the center of the guide groove 61, so as to achieve quick insertion.

[0037] The male guide post 3 and the insulator 1 are integrally formed by in-mold injection molding. A first annular positioning groove 31 is provided on the outer periphery of the middle portion of the male guide post 3, and the first positioning protrusion 11 of the insulator 1 is embedded in the first annular positioning groove 31, thereby ensuring a stable connection between the male guide post 3 and the insulator 1. The female guide post 6 and the insulating seat 4 are integrally formed by in-mold injection molding. A second annular positioning groove 62 is provided on the outer periphery of the middle portion of the female guide post 6, and the second positioning protrusion 41 of the insulating seat 4 is embedded in the second annular positioning groove 62, thereby ensuring a stable connection between the female guide post 6 and the insulating seat 4.

[0038] The outer surface of the male terminal 2 is provided with a third annular positioning groove 22; the male terminal 2 and the insulator 1 are integrally formed by in-mold injection molding, and the third positioning protrusion 12 formed in the insulator 1 is embedded in the third annular positioning groove 22, so that the male terminal 2 and the insulator 1 form a stable connection.

[0039] The outer surface of the female terminal 5 is provided with a fourth annular positioning groove 53; the female terminal 5 and the insulating seat 4 are formed into one piece by in-mold injection molding, and the fourth positioning protrusion 42 formed in the insulating seat 4 is embedded in the fourth annular positioning groove 53, so that the female terminal 5 and the insulator 1 form a stable connection.

[0040] It is worth mentioning that the male terminal 2 and the male terminal guide post 3 are integrally formed with the insulator 1 through in-mold injection molding; the female terminal 5, the female terminal guide post 6 and the insulating seat 4 are integrally formed with the in-mold injection molding.

[0041] The upper surface of the female end guide post 6 is flush with the upper surface of the insulating base 4, and the lower end of the female end guide post 6 extends beyond the lower surface of the insulating base 4 and protrudes beyond the solder foot 52 of the female terminal 5. The lower end of the female end guide post 6 is used to insert with the PCB board and also serves as a guide. That is, the lower end of the female end guide post 6 is first inserted with the PCB board, and then the solder foot 52 of the female terminal 5 is inserted with the PCB board. This ensures that the solder foot 52 of the female terminal 5 can accurately align with the pads of the PCB board, avoiding soldering flipping or misalignment, and ensuring the stability and service life of the assembly structure.

[0042] The male terminal 2 has a wiring groove 23 at its upper end for welding and fixing to the metal core of the conductor. The upper end of the male terminal 2 also has a beveled surface 24 penetrating the wiring groove 23. A through hole 25 is formed inwards from the outer periphery of the upper end of the male terminal 2 to prevent poor cold soldering. In use, the metal core of the conductor is inserted into the wiring groove 23 at the upper end of the male terminal 2, and solder is applied to fix it in place. Because the upper end of the male terminal 2 has a beveled surface 24 penetrating the wiring groove 23, the solder covers the beveled surface 24, further ensuring the stability of the soldering. Simultaneously, the through hole 25 formed inwards from the outer periphery of the upper end of the male terminal 2 prevents poor cold soldering during welding, thus ensuring higher soldering quality.

[0043] The female terminal 5 is further provided with an inner sleeve 7 inside the guide groove 51 to improve conductivity and clamping force. The inner sleeve 7 has a through hole 711 through which the first contact portion 21 of the male terminal 2 passes, and the lower end of the inner sleeve 7 has a guide arm 72 for elastic contact with the outer surface of the first contact portion 21. The end of the guide arm 72 is a free end, and the degree of freedom of the guide arm 72 is close together. The inner sleeve 7 increases the clamping force of the male terminal 2 after it is inserted into the guide groove 51 of the female terminal 5, and at the same time improves the conductivity between the male terminal 2 and the female terminal 5.

[0044] In this embodiment, there are four guide arms 72.

[0045] The inner sleeve 7 includes a non-closed cylindrical body 71 and at least two guide arms 72 formed by bending and extending along the lower end of the cylindrical body 71. The cylindrical body 71 has the through hole 711. After being compressed from the outside to the inside, the cylindrical body 71 is inserted into the guide groove 51. The elastic force formed by the cylindrical body 71 from the inside to the outside engages and positions with the inner wall of the guide groove 51, thereby ensuring that the inner sleeve 7 is stably installed in the guide groove 51 of the female terminal 5. In addition, steps or grooves can be provided on the inner wall of the guide groove 51 of the female terminal 5 to further limit the cylindrical body 71 of the inner sleeve 7, so that the inner sleeve 7 can be more stably installed in the guide groove 51 of the female terminal 5, thereby improving the quality of the socket 400.

[0046] In summary, since the plug 100 and the socket 400 are respectively provided with corresponding male end guide post 3 and female end guide post 6, and the lower end of the male end guide post 3 of the plug 100 protrudes beyond the lower end of the first contact part 21, when the plug 100 is inserted into the socket 400, the lower end of the male end guide post 3 will first align with the guide groove 61 of the female end guide post 6 in the socket 400, ensuring that the plug 100 and the socket 400 are in the correct symmetrical position. After the male end guide post 3 has been inserted into the guide groove 61 for a short distance, the first contact part 21 of the male terminal 2 in the plug 100 will be inserted into the guide groove 51 of the female terminal 5. As the male end guide post 3 and the first contact part 21 of the male terminal 2 continue to be inserted, the plug 100 and the socket 400 complete a stable connection. In the above process, due to the prior docking of the guide grooves 61 of the male guide post 3 and the female guide post 6, the plug 100 and the socket 400 are automatically guided, so that the male terminal 2 of the plug 100 and the female terminal 5 of the socket 400 are accurately aligned, ensuring that the plug 100 and the socket 400 are successfully connected and forming a quick connection, improving the connection efficiency. At the same time, it can also avoid damage to the male and female terminals, ensuring the service life of the entire connector.
