Abstract
Description
Technical Field
[0001] This application relates to the field of connectors, and in particular to a high-security connector. Background Technology
[0002] Connectors, as an indispensable component of electronic devices, play an extremely important role in modern industry and social life. Among them, wire-to-wire connectors are more widely used in actual production and use. Wire-to-wire connectors are electronic components used to connect two active devices, or two single wires or corresponding wires in two cables.
[0003] In existing technologies, most wire-to-wire connectors include a male terminal assembly and a female terminal assembly, which are often connected by a snap-fit mechanism.
[0004] For example, patent CN218940082U discloses a connector with a terminal anti-retrieval structure. This connector includes a first assembly and a corresponding second assembly. The first and second assemblies are respectively provided with a snap-fit boss and a hook, which engage to assemble the first and second assemblies together. In practical applications, this connector is prone to accidental contact, which could unlock the assembly of the first and second assemblies, posing a risk of disconnection. Therefore, there is a need to design a device that can prevent accidental contact of the insertion spring from unlocking the first and second assemblies, reducing the safety hazards caused by the first and second assemblies being exposed after accidental unlocking. Utility Model Content
[0005] To ensure a more stable engagement between the male and female components, a highly secure connector is provided.
[0006] The above-mentioned objective of this application is achieved through the following technical solution:
[0007] A high-security connector includes a male terminal assembly and a female terminal assembly. The male terminal assembly includes a male socket and a insertion head. The male socket has an insertion groove on one side, and the insertion head is installed in the insertion groove. The female terminal assembly includes a female socket, a spring-loaded contact, a fixing plate, and a baffle. The fixing plate and baffle are installed on one side of the female socket. The spring-loaded contact includes a contact end, a connecting section, and a pressing end distributed sequentially along its length. The connecting section is connected to the fixing plate. The contact end is inserted and fitted into the insertion groove. The baffle is located on the side of the contact end facing away from the female socket. The spring-loaded contact has a through insertion groove along its thickness. After the male socket is inserted into the female socket and engaged, the insertion head is inserted into the through insertion groove of the contact end.
[0008] By adopting the above technical solution, pressing the spring on one side of the pressing end can lift the spring on the other side of the plug end, separating the plug head from the plug slot, which facilitates the assembly and disassembly of the connector. At the same time, a baffle is added. When the pressing end is pressed, the spring on one side of the plug end is lifted. The baffle restricts the spring on one side of the plug end, and it can only be pulled out in the direction away from the male socket, so that the male socket and female socket are separated. This avoids the incorrect operation of the spring and thus unlocks the assembly of the male socket and female socket, reducing the safety hazards caused by the male socket and female socket being exposed alone.
[0009] Optionally, the side of the pressing end facing the male socket is fixedly connected to the connecting section in an arc shape, and the arc-shaped connection is located on the side of the pressing end facing away from the female socket.
[0010] By adopting the above technical solution, when the male terminal component and the female terminal component are separated, the pressing end is pressed and pulled out away from the male socket. The arc at the connection between the pressing end and the connecting section provides a support when the pressing end is pulled out, which facilitates the female socket to be pulled out from the male socket and makes it easier to assemble and disassemble the male terminal component and the female terminal component.
[0011] Optionally, the female socket has a pressing cavity on the side of the fixing plate facing away from the male socket, and the pressing end is located inside the pressing cavity.
[0012] By adopting the above technical solution, the pressing end is located inside the pressing cavity of the female socket, making the pressing end less susceptible to collisions with external parts, thus reducing the risk of the male socket and female socket separating due to collisions with the pressing end.
[0013] Optionally, the insertion slot is further provided with two limiting plates, and the insertion spring is inserted between the two limiting plates.
[0014] By adopting the above technical solution, the insertion spring is inserted between two limiting plates. The two limiting plates limit the two sides of the insertion spring, so that the insertion spring can only move towards or away from the male socket between the two limiting plates. At the same time, after long-term use, it avoids misalignment between the insertion spring and the insertion head, and improves the connection stability between the male plug and the female plug.
[0015] Optionally, the female end assembly further includes a cover plate and a connecting plate. There are at least two connecting plates, and the two connecting plates are respectively installed on the female sockets on the side of the two limiting plates facing away from the insertion spring. The cover plate is located on the side of the baffle facing away from the insertion spring. The connecting plate is provided with a slide rail, and the cover plate is slidably connected to the slide rail. The cover plate slides from the insertion end toward the pressing end.
[0016] By adopting the above technical solution, a cover plate is added to prevent dust or impurities from remaining on the insertion spring and the insertion head, thereby improving the connection stability of the buckle; at the same time, the cover plate is slidably connected to the slide rail, and the cover plate can slide from the insertion end side to the pressing end side, which facilitates the adjustment of the cover plate position.
[0017] Optionally, the slide rail is provided with at least two limiting holes, and the cover plate is provided with at least two limiting protrusions on both sides, with the limiting holes engaging with the limiting protrusions.
[0018] By adopting the above-mentioned design solution, the limiting convex circle and the limiting hole are engaged to limit the position of the cover plate. When the cover plate slides to a certain position on the slide rail, the limiting convex circle is engaged in the limiting hole to limit the position of the cover plate, which facilitates the fixation of the position of the cover plate.
[0019] Optionally, the female end assembly further includes a sealing ring, and a first slot is provided on the side of the female socket facing the male socket. The sealing ring is embedded and abuts against the first slot, and the end of the male socket facing the female socket presses against the sealing ring.
[0020] By adopting the above technical solution and adding a sealing gasket, the male and female sockets are kept in a sealed environment. When the connector is used in some automotive applications, it will be in a humid environment. The sealing gasket prevents water from seeping into the connector from the outside, thus improving the connection sealing between the male and female sockets.
[0021] Optionally, a limiting groove is formed on one side of the female socket, and a limiting post is installed on one side of the male socket, with the limiting post fitting into the limiting groove.
[0022] By adopting the above technical solution, when the male socket is inserted into the female socket, the guiding function of the limiting post prevents the male socket and female socket from being misaligned, adds a foolproof effect, and makes the connection between the male socket and female socket more accurate.
[0023] In summary, this application has at least the following beneficial effects:
[0024] 1. Pressing one end of the contact spring lifts the part where the contact spring and the insertion head are connected, facilitating the assembly and disassembly of the connector. A baffle is added so that when the pressing end is pressed, the contact spring at the insertion end is lifted, and the baffle restricts the contact spring at the insertion end, preventing incorrect operation of the contact spring and thus unlocking the assembly of the male and female sockets, reducing the safety hazards caused by the male and female sockets being exposed alone.
[0025] 2. A cover plate has been added to prevent dust or debris from remaining in the insert spring and insertion head, thus improving the connection stability of the buckle; at the same time, the cover plate is slidably connected to the slide rail, making the adjustment of the cover plate more convenient.

Detailed implementation method:
[0034] The following section provides a more detailed description, in conjunction with the accompanying diagrams:
[0035] As attached Figure 1 As shown, a high-security connector includes a male terminal component 1 and a female terminal component 2.
[0036] As attached Figure 1 and attached Figure 2 As shown, the male terminal assembly 1 includes nine male terminals 11, and the female terminal assembly 2 includes nine female terminals 21.
[0037] Both the male terminal assembly 1 and the female terminal assembly 2 have nine sockets, and the male terminal 11 and the female terminal 21 are respectively inserted into the corresponding sockets.
[0038] As attached Figure 3 and attached Figure 4As shown, the female terminal assembly 2 includes a female socket 22, a spring clip 23, and a fixing plate 24.
[0039] The female socket 22 is square in shape, with rounded corners on all four sides of the outer wall. One side of the outer wall of the female socket 22 is fixedly connected to the fixing plate 24, and the fixing plate 24 is perpendicular to the female socket 22.
[0040] The insert spring 23 includes an insert end 231, a connecting section 232 and a pressing end 233 distributed sequentially along its length. One end of the connecting section 232 is fixedly connected to the pressing end 233, and the other end is fixedly connected to the insert end 231. The insert spring 23 is perpendicular to the fixing plate 24.
[0041] The pressing end 233 is fixedly connected to the connecting section 232 in an arc shape on the side facing the male socket 12, and the arc-shaped connection is located on the side of the pressing end 233 facing away from the female socket 22. The arc at the connection between the pressing end 233 and the connecting section 232 provides a support when the pressing end 233 is pulled out, making it easier for the female socket 22 to be pulled out from the male socket 12.
[0042] The female socket 22 is located on the side of the fixing plate 24 facing away from the male socket 12 and has a pressing cavity 235. The pressing end 233 is located in the pressing cavity 235. The pressing end 233 is not easily hit by external parts, which reduces the risk of the male socket 12 and the female socket 22 being separated by impact with the pressing end 233.
[0043] The insert spring 23 also has an insert through groove 234 that runs through the thickness. The insert through groove 234 is distributed along the length of the insert spring 23 and installed in the connecting section 232. The insert through groove 234 is located on the side of the pressing end 233 and communicates with the pressing cavity 235. The insert through groove 234 is located on the side of the insert end 231 and communicates with the inner cavity of the female insert 22.
[0044] The female end assembly 2 also includes a baffle 25, a cover plate 26, and a connecting plate 27.
[0045] The female socket 22 is also equipped with two integrally formed connecting plates 27. The two connecting plates 27 are parallel to the plug spring 23 and are located on both sides of the plug spring 23. The two connecting plates 27 are also equipped with baffles 25. The baffles 25 are located on the side of the plug end 231 facing away from the female socket 22, and the side of the baffles 25 facing the female socket 22 is parallel to the female socket 22.
[0046] When the pressing end 233 is pressed into the pressing cavity 235, the plug end 231 is lifted towards the baffle 25. The plug end 231 abuts against the baffle 25 on the side facing the female socket 22. The baffle 25 limits the lifting range of the plug end 231 to prevent excessive pressing of the pressing end 233 from damaging the plug spring 23 and improve the connection reliability of the male socket 12 and the female socket 22.
[0047] A cover plate 26 is also installed on the side of the two connecting plates 27 facing away from the insertion spring 23. The shape of the cover plate 26 is the same as that of the baffle 25. The cover plate 26 is parallel to the baffle 25 and is located on the side of the baffle 25 facing away from the insertion end 231. A slide rail 271 is also provided on the side of the two connecting plates 27 facing away from the insertion spring 23. The cover plate 26 is slidably connected to the slide rail 271. The cover plate 26 can slide from the insertion end 231 toward the pressing end 233, which facilitates the adjustment of the position of the cover plate 26 and facilitates the assembly and disassembly of the male socket 12 and the female socket 22.
[0048] On the side of the two connecting plates 27 facing away from the insert spring 23, there are also two limiting holes 272. The two limiting holes 272 are both round holes.
[0049] On both sides of the cover plate 26, there are also two limiting protrusions 261 that match the limiting holes 272. The two limiting protrusions 261 are both convex in shape. The limiting protrusions 261 engage with the limiting holes 272. The convex shape of the limiting protrusions 261 makes it easy for the limiting protrusions 261 to slide into the limiting holes 272, while also restricting the position of the cover plate 26.
[0050] When the cover plate 26 slides to a certain position on the slide rail 271, the limiting protrusion 261 engages in the limiting hole 272 to limit the cover plate 26, eliminating the need for cumbersome fixing methods and making the fixing of the cover plate 26 more convenient.
[0051] As attached Figure 5 and attached Figure 6 As shown, the male terminal assembly 1 includes a male socket 12, a plug head 13, and a limiting plate 14.
[0052] Two limit plates 14 are installed on one side of the male socket 12. The two limit plates 14 and the male socket 12 together form an insertion groove 15.
[0053] The insertion head 13 is installed on the insertion slot 15. The insertion head 13 is located on the side of the male socket 12 facing the female socket 22. The insertion head 13 is trapezoidal in shape. The side of the insertion head 13 facing the female socket 22 is inclined, and the side facing away from the female socket 22 is flat.
[0054] When the male socket 12 is inserted into the female socket 22 and engaged, the insertion slot 15 abuts against the side of the female socket 22 facing the male socket 12, the insertion end 231 and the insertion slot 15 are in contact, and the limiting plate 14 is inserted between the connecting plate 27 and the insertion spring 23. The insertion spring 23 is inserted between the two limiting plates 14, and the two limiting plates 14 are parallel to the insertion spring 23.
[0055] The insertion head 13 engages with the insertion slot 234 on one side of the insertion end 231, and the side of the insertion end 231 facing the male socket 12 is inclined, facilitating sliding with the inclined surface of the insertion head 13, making it easier for the insertion head 13 to slide into the insertion slot 234. Pressing the insertion spring 23 on one side of the pressing end 233 can lift the insertion spring 23 on the side of the insertion end 231, thereby realizing the adjustment of the male socket 12 and the female socket 22, which is more time-saving and labor-saving.
[0056] Two limiting plates 14 limit the insertion spring 23, so that the insertion spring 23 can only move between the two limiting plates 14 toward or away from the male socket 12. After long-term use, this prevents the insertion spring 23 from being misaligned with the insertion head 13 and improves the connection stability between the male plug 12 and the female plug 22.
[0057] As attached Figure 2 and attached Figure 7 As shown, the female terminal assembly 2 also includes a sealing ring 28, which is square in shape. A first slot 221 is provided on the side of the female socket 22 facing the male socket 12. The sealing ring 28 is embedded and abuts against the first slot 221. When the male terminal assembly 1 is inserted into the female terminal assembly 2, the end of the male socket 12 facing the female socket 22 presses against the sealing ring 28. This ensures a sealed environment between the male terminal assembly 1 and the female terminal assembly 2, preventing water from seeping into the connector and affecting the connection stability between the male terminal 11 and the female terminal 21.
[0058] A limiting groove 29 is opened on one side of the female socket 22, and a limiting post 16 matching the limiting groove 29 is installed on one side of the male socket 12. The limiting groove 29 and the limiting post 16 are located on the same side. When the male socket 12 is inserted into the female socket 22, the limiting groove 29 and the limiting post 16 are engaged. The guiding function of the limiting post 16 prevents the male terminal component 1 and the female terminal component 2 from being misaligned and is increased to prevent foolproof connection.
[0059] The advantages of this embodiment are as follows: Firstly, when the insertion spring 23 of the pressing end 233 is pressed, the insertion spring 23 on one side of the insertion end 231 is lifted, and the baffle 25 blocks the insertion spring 231 on one side of the insertion end 231, preventing incorrect operation of the insertion spring 231 and thus unlocking the assembly of the male socket 12 and the female socket 22, reducing the safety hazards caused by the male socket 12 and the female socket 22 being exposed alone; Secondly, the addition of a cover plate 26 prevents some dust or debris from remaining in the insertion slot 234, improving the connection stability of the buckle. The cover plate 26 is slidably connected to the connecting plate 27, and the cover plate 26 covers the female socket 22 from the side of the insertion end 231 toward the side of the pressing end 233, preventing accidental contact of the pressing end 233, making adjustment more convenient and safer.
[0060] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
