Description

Technical Field

[0001] This application relates to the technical field of automotive connectors, and in particular to a two-locking female terminal assembly of an automotive multi-row cylinder connector. Background Technology

[0002] Against the backdrop of the automotive industry's upgrade towards intelligence and integration, connectors, as core connection components of automotive electrical systems, directly impact the operational safety and reliability of the entire vehicle. Among them, multi-row cylinder connectors, with their multi-row terminal layout, enable the centralized connection of more cables, effectively saving installation space around automotive cylinders. They meet the high-efficiency signal transmission and power supply requirements between automotive cylinders and external circuits, and are now widely used in various automotive cylinder connection scenarios. They have become one of the key components ensuring the normal operation of automotive hydraulic and control systems, and their structural design and service life have attracted significant industry attention.

[0003] In related technologies, a multi-row cylinder connector for automobiles includes a female terminal assembly connected to an external cable and a male terminal assembly mounted on an automobile cylinder. The female terminal assembly includes a female housing, an anti-disengagement component, and a terminal block fixed within the female housing. The male terminal assembly includes a male housing and conductive pins fixed within the male housing. The female housing has four rows of mounting holes along its own axis and four anti-disengagement holes that penetrate the four rows of mounting holes along a direction perpendicular to its own axis. The anti-disengagement component includes a mounting plate and four anti-disengagement rods fixed on the mounting plate. Before the terminal block is inserted into the mounting hole, the four anti-disengagement rods on the mounting plate are inserted into the four anti-disengagement holes respectively, and each set of anti-disengagement rods simultaneously engages with a pre-drilled notch on the terminal block in the same row of mounting holes, thereby preventing the installed terminal block from disengaging from the mounting hole.

[0004] Although the existing technology can achieve the anti-disengagement function of the terminal to a certain extent through the cooperation of four sets of anti-disengagement holes and anti-disengagement rods, the fact that all four sets of anti-disengagement holes penetrate the four rows of mounting holes of the female housing will significantly weaken the overall structural strength of the female housing. Under the vibration environment of long-term vehicle operation, the female housing is prone to cracking and damage, which directly affects the service life of the female terminal components and reduces the reliability of the entire multi-row cylinder connector. It cannot meet the usage requirements of long-term stable operation of automobiles and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a two-lock female terminal assembly for a multi-row cylinder connector for automobiles, which solves the problems of weak structural strength and easy damage of the female housing in the above-mentioned related technologies.

[0006] The two-locking female end assembly of the multi-row cylinder connector for automobiles provided in this application adopts the following technical solution: A two-lock female terminal assembly for a multi-row cylinder connector for automobiles includes a female housing and an anti-disengagement component. The female housing has several rows of mounting holes along its own axis, with an even number of rows, and each pair of adjacent rows of mounting holes forms a group. An anti-disengagement hole is formed on the outer side of the female housing along a direction perpendicular to its own axis, located between two mounting holes in the same group and communicating with the mounting holes. A terminal block connected to the inner core wire of an external cable is provided in the mounting hole, and an anti-disengagement notch is provided on the outer periphery of the terminal block. The terminals in two adjacent rows of mounting holes are distributed with the anti-disengagement notch facing the anti-disengagement hole. The anti-disengagement component includes a mounting plate and several anti-disengagement rods fixed on the mounting plate. After the terminal block is installed, a single anti-disengagement rod passes through the anti-disengagement hole and simultaneously passes through the anti-disengagement notch on the terminal block in the two mounting holes in the same group.

[0007] By adopting the above technical solution, the mounting holes are arranged in even-numbered rows and grouped in pairs. A single anti-detachment rod can simultaneously penetrate the anti-detachment holes between the two rows of mounting holes in the same group and the anti-detachment notches of the corresponding terminals, achieving a "one rod locks two groups" limiting effect. This significantly reduces the number of anti-detachment holes, avoids excessive openings that weaken the structural strength of the mother shell, reduces the risk of cracking and damage to the mother shell under automotive vibration environments, and extends the service life of the mother terminal assembly. At the same time, it simplifies the structure and assembly process of the anti-detachment component, improves the portability and assembly efficiency of the mother terminal assembly, ensures stable terminal connections, and meets the requirements for long-term stable operation of automobiles.

[0008] Optionally, a mounting groove is provided on one side of the mother shell, which communicates with several anti-detachment holes and allows the mounting plate to be inserted. A clearance groove is provided on the side of the mother shell away from the mounting groove, which communicates with several anti-detachment holes. An anti-detachment hook is fixed on the outer periphery of the end of the anti-detachment rod away from the mounting plate, which engages with the inner edge of the clearance groove.

[0009] By adopting the above technical solution, the mounting plate for the anti-detachment component is precisely engaged and positioned within the recess, allowing the recess to fit and engage with the anti-detachment hook at the end of the anti-detachment rod, forming a two-way limiting structure. This ensures that the anti-detachment rod accurately penetrates the anti-detachment hole and the anti-detachment notch of the wiring terminal, guaranteeing the reliability of the limiting lock, and also prevents the anti-detachment rod from axially shifting or coming off during vehicle vibration, further improving the anti-detachment effect.

[0010] Optionally, clamping grooves are provided at the front edges of both the left and right sides of the mother shell.

[0011] By adopting the above technical solution, the clamping grooves opened on the front edges of the left and right sides of the mother shell provide suitable space for the subsequent storage of the protective shell, making it easy for the protective shell to fit snugly against the mother shell in the stored state, achieving comprehensive protection of the clamping grooves. At the same time, the clamping grooves can be adapted to external clamping tools or connecting structures, making it convenient for operators to clamp, transport, and install the mother end components, improving operational convenience.

[0012] Optionally, protective shells are rotatably connected to the left and right edges of the front side of the mother shell, and locking elements are provided on the outside of the protective shells; the two protective shells can rotate towards each other to a protective state where they abut against each other, and rotate away from each other to a storage state where they abut against the left and right sides of the mother shell; when the two protective shells are in the protective state, a tightening opening is provided on the side of the two protective shells that are close to each other for external cables to pass through. At this time, the two protective shells protect the exposed parts of several core wires on the external cable, and the locking elements can limit and lock the two protective shells in this state.

[0013] By adopting the above technical solution, in the protected state, the two protective shells fit snugly around the exposed core of the external cable, preventing corrosion from dust, water stains, and other impurities, and reducing the risk of cable short circuits and damage. In the stored state, the protective shell fits snugly against the side of the mother shell, without occupying extra space, facilitating the transportation and storage of the mother terminal assembly. The tightening opening is adapted for the insertion of external cables, and the locking mechanism ensures the stability of the protective shell, further improving protection reliability and extending the service life of the cable and mother terminal assembly.

[0014] Optionally, the locking element includes an elastic locking rod located outside the protective shell and having elastic shortening properties. One end of the elastic locking rod is rotatably connected to the outer side of the protective shell where a tightening opening is provided, and the rotating surface of the elastic locking rod is parallel to its own mounting surface. An elastic hook is fixedly provided at the other end of the elastic locking rod, and a locking protrusion is fixedly provided on the outer side of the protective shell. When in the protective state, the elastic hook on one of the two protective shells can engage with the locking protrusion on the other protective shell as the elastic locking rod rotates, and the elastic hook is in the locked state at this time.

[0015] By adopting the above technical solution, the elastic locking rod combines elasticity and rotatability. Combined with the elastic hook and locking protrusion, it can quickly lock and unlock the two protective shells. The elasticity of the hook facilitates engagement and disengagement, making it convenient to operate and suitable for portable use.

[0016] Optionally, when the two elastic locking rods are in the locked state, a limiting plate can be detachably installed on their outer periphery that is close to each other, and the two limiting plates abut against each other at this time; a limiting notch is opened on the side of the two limiting plates that is close to each other, and an elastic pad that can abut against the outer periphery of the external cable is fixed on the inner wall of the limiting notch.

[0017] By adopting the above technical solution, the limiting plates abut against each other after being locked by the two elastic locking rods. The limiting cavity formed by the limiting notch is adapted to the passage of external cables. The rubber elastic pad tightly abuts against the outer circumference of the cable, realizing the auxiliary limiting of the cable. The elasticity of the elastic pad can buffer vibration, prevent the cable from shaking or shifting during use, improve the connection stability between the cable and the terminal block, and avoid cable detachment and poor contact.

[0018] Optionally, the limiting plate is rotatably connected to the outer peripheral surface of the elastic locking rod, and elastic snap-fit ​​members are provided on the two opposite outer surfaces of the limiting plate. A baffle is fixed on the outer surface of the protective shell with the tightening opening. A first groove is provided on the side of the two baffles that are close to each other when the two protective shells are in the protective state. The elastic snap-fit ​​members can be snapped into the first groove when the two limiting plates are rotated to the state of mutual abutment.

[0019] By adopting the above technical solution, the rotatable design of the limiting plate facilitates position adjustment according to usage requirements, adapting to both protective and storage states of the protective shell. The elastic snap-fit ​​component engages with the first groove on the baffle, quickly achieving a fixed position where the two limiting plates are in contact, preventing rotation or displacement of the limiting plates during vehicle vibrations and ensuring stable cable limiting performance. The baffle not only limits the elastic locking rod but also provides a positioning reference for the elastic snap-fit ​​component. The coordinated structure enhances the stability and integrity of the limiting structure, further ensuring the reliability of the female terminal assembly.

[0020] Optionally, the elastic snap-fit ​​component includes a compression spring and an arc-shaped protrusion. The baffle plate has a placement groove for the compression spring and the arc-shaped protrusion to be placed in. The compression spring squeezes one side of the arc-shaped protrusion, causing the protruding part of the arc-shaped protrusion to protrude from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion is an arc surface, and the arc length corresponding to this arc surface is a minor arc.

[0021] By adopting the above technical solution, the compression spring provides continuous elastic force to the arc-shaped protrusion, ensuring that the arc-shaped protrusion always remains in a protruding state, facilitating quick engagement with the first and second grooves and improving the engagement reliability of the elastic engagement component. The inferior arc surface design of the arc-shaped protrusion allows it to smoothly slide into the groove during engagement and easily pop out when disengaged, making operation convenient and avoiding the problems of being too tight to disassemble or too loose to fall off.

[0022] Optionally, a second groove is provided on the inner wall of the clamping groove; when the two protective shells are in the storage state, the elastic hook can be rotated to a fixed state where it engages with the locking protrusion on the protective shell. At this time, the limiting plate can be rotated to a position where it abuts against the side of the protective shell facing the mother shell and is accommodated in the clamping groove. The elastic snap-fit ​​member is then inserted into the second groove, and the outer side of the elastic locking rod away from the limiting plate abuts against one side of the baffle.

[0023] By adopting the above technical solution, the second groove is adapted to the elastic snap-fit ​​component, combined with the snap-fit ​​of the elastic hook and the locking protrusion, and the abutment of the baffle and the elastic locking rod, to achieve multiple limiting and fixing of the protective shell in its stored state, preventing the protective shell from rotating or shifting during transportation and storage. The limiting plate is housed in the clamping recess, which not only allows for the storage of the limiting plate but also further protects the clamping recess, preventing impurities from adhering. The multiple limiting structures work together to improve the stability of the protective shell in its stored state, while achieving rational utilization of the structure, balancing storage convenience and protective effect.

[0024] Optionally, a guide slope is provided at the opening edge of the clamping groove.

[0025] By adopting the above technical solution, the guide slope of the clamping trough opening edge plays a guiding role, which makes it easy for the limiting plate to smoothly rotate into the clamping trough in the storage state, avoiding jamming or collision between the limiting plate and the edge of the trough opening edge, protecting the limiting plate and the mother shell structure from damage, and improving the ease of operation.

[0026] In summary, this application includes the following beneficial technical effects: In this application, the mounting holes are arranged in even-numbered rows and grouped in pairs. A single anti-disengagement rod can simultaneously penetrate the anti-disengagement hole between two rows of mounting holes in the same group and the anti-disengagement notch of the corresponding terminal block, achieving a "one rod locks two groups" limiting effect. This significantly reduces the number of anti-disengagement holes, avoids excessive openings that weaken the structural strength of the mother shell, reduces the risk of cracking and damage to the mother shell under automotive vibration conditions, and extends the service life of the mother terminal assembly.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings. Example

[0030] Reference Figure 1 , Figure 2 and Figure 3 A two-lock female end assembly for a multi-row cylinder connector for automobiles includes a female housing 1 and an anti-disengagement component 2. The female housing 1 has several rows of mounting holes 11 along its own axis, the number of rows of mounting holes 11 is even, and every two rows of adjacent mounting holes 11 form a group. The anti-disengagement component 2 includes a mounting plate 21 and two anti-disengagement rods 22 fixed on the mounting plate 21. An anti-disengagement hole 12 is provided on the outer side of the female housing 1 along the direction perpendicular to its own axis, located between two mounting holes 11 in the same group and communicating with the mounting holes 11. The number of anti-disengagement holes 12 is half the number of rows of mounting holes 11, and a terminal 7 connected to the inner core wire of the external cable is provided in the mounting hole 11. An anti-disengagement notch 71 is provided on the outer periphery of the terminal 7. The terminal 7 in two adjacent rows of mounting holes 11 are distributed along the anti-disengagement notch 71 towards the anti-disengagement hole 12. In other embodiments, the number of rows of mounting holes 11 can also be 2, 6, 8, etc., which will not be described in detail here. After the terminal block 7 is installed, the single anti-disengagement rod 22 penetrates the anti-disengagement hole 12 and also penetrates the anti-disengagement notch 71 on the terminal block 7 in the two mounting holes 11 of the same group. In this way, the single anti-disengagement rod 22 simultaneously limits and locks the terminal block 7 in the two rows of mounting holes 11 of the same group.

[0031] Reference Figure 2, Figure 3 and Figure 4 The front edge of both sides of the mother shell 1 is provided with a clamping groove 15, and the opening edge of the clamping groove 15 is provided with a guide slope 151; a mounting groove 13 is provided on one side of the mother shell 1, which is connected to the two anti-detachment holes 12 and is used for the mounting plate 21 to be inserted; a clearance groove 14 is provided on the side of the mother shell 1 away from the mounting groove 13, which is connected to the two anti-detachment holes 12; and an anti-detachment hook 23 is fixed on the outer periphery of the end of the anti-detachment rod 22 away from the mounting plate 21. During the assembly of the female end assembly, the single anti-detachment rod 22 passes through the anti-detachment hole 12 and also passes through the anti-detachment notch 71 on the wiring terminal 7 in the two mounting holes 11 of the same group. The mounting plate 21 is placed into the mounting groove 13, and the anti-detachment hook 23 is engaged with the inner edge of the clearance groove 14.

[0032] The implementation principle of this application embodiment is as follows: During the assembly of the female terminal assembly, the terminals 7 are first inserted into the mounting holes 11 of the female housing 1, so that the anti-disengagement notches 71 of the terminals 7 in the two adjacent rows of mounting holes 11 in the same group all face the anti-disengagement holes 12 between the two groups of mounting holes 11. Then, the mounting plate 21 of the anti-disengagement component 2 is aligned with the mounting groove 13 of the female housing 1, and the mounting plate 21 is pushed so that the two anti-disengagement rods 22 are inserted into the corresponding anti-disengagement holes 12 respectively. Each anti-disengagement rod 22 simultaneously penetrates the anti-disengagement notches 71 of the terminals 7 in the two rows of mounting holes 11 in the same group until the mounting plate 21 is engaged in the mounting groove 13, and the anti-disengagement hooks 23 at the ends of the anti-disengagement rods 22 are engaged in the inner edge of the clearance groove 14, thus completing the assembly. Example

[0033] Reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that protective shells 3 are rotatably connected to the left and right edges of the front side of the mother shell 1, and locking members 4 are provided on the outside of the protective shells 3; the two protective shells 3 can be rotated to a protective state where they abut against each other, and rotated to a storage state where they abut against the left and right sides of the mother shell 1; when the two protective shells 3 are in the protective state, a tightening opening 31 for external cables to pass through is provided on the side that is close to each other. When the mother-end component is assembled, the external cable is not yet connected to the terminal 7. The two protective shells 3 can be adjusted to the storage state. At this time, the protective shells 3 can be used to protect the clamping groove 15 on the outer side of the mother shell 1, reducing the possibility of external impurities adhering to the inner wall of the clamping groove 15 during transportation. When the female terminal assembly is used, the external cable has been pre-connected to the terminal 7 inside the female housing 1. Then, the two protective housings 3 are adjusted to the protective state. At this time, the two protective housings 3 protect the exposed parts of several core wires on the external cable, and the locking member 4 limits and locks the two protective housings 3 in this state.

[0034] Reference Figure 5 The locking component 4 includes an elastic locking rod 41 located outside the protective shell 3 and having elastic shortening properties. One end of the elastic locking rod 41 is rotatably connected to the outer side of the protective shell 3 where a tightening opening 31 is provided. The rotating surface of the elastic locking rod 41 is parallel to its own mounting surface. The other end of the elastic locking rod 41 is fixedly provided with an elastic hook 42, and a locking protrusion 32 is fixedly provided on the outer side of the protective shell 3. When the female end assembly is assembled (that is, when the two protective shells 3 are in the protective state), the elastic hook 42 on one of the two protective shells 3 can be engaged with the locking protrusion 32 on the other protective shell 3 as the elastic locking rod 41 rotates. The elastic hook 42 is in the locked state at this time, thereby realizing the limit locking of the two protective shells 3 in this state.

[0035] Reference Figure 5 When the two elastic locking rods 41 are in the locked state, a limit plate 5 can be detachably installed on the outer periphery that is close to each other. The two limit plates 5 are in contact with each other at this time. A limit notch 51 is opened on the side of the two limit plates 5 that is close to each other, and an elastic pad 52 made of rubber is fixed on the inner wall of the limit notch 51. When the female end assembly is used, the external cable passes through the limiting cavity surrounded by the two limiting notches 51. At this time, the elastic pad 52 on the inner wall of the limiting notch 51 abuts against the outer peripheral surface of the external cable, improving the assembly stability of the external cable and the female housing 1.

[0036] Reference Figure 6 and Figure 7 The limiting plate 5 is rotatably connected to the outer peripheral surface of the elastic locking rod 41. The two outer surfaces of the limiting plate 5 are provided with elastic snap-fit ​​pieces 6. The outer surface of the protective shell 3 with the tightening opening 31 is fixed with a baffle 33. The two baffles 33 are provided with a first groove 331 on the side of the two protective shells 3 when they are close to each other in the protective state. The elastic snap-fit ​​component 6 includes a compression spring 61 and an arc-shaped protrusion 62. The baffle 33 has a placement groove 53 for the compression spring 61 and the arc-shaped protrusion 62 to be placed. The compression spring 61 squeezes one side of the arc-shaped protrusion 62 so that the protruding part of the arc-shaped protrusion 62 protrudes from the opening of the placement groove 53. The outer surface of the protruding part of the arc-shaped protrusion 62 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. When the two protective shells 3 are in the protective state and the two limiting plates 5 are rotated to the state of mutual contact, the elastic snap-fit ​​6 snaps into the corresponding first groove 331, thereby limiting and fixing the two limiting plates 5 in this state and enhancing the corresponding installation stability.

[0037] Reference Figure 9 , Figure 10 and Figure 11A second groove 152 is provided on the inner wall of the clamping groove 15. When the two protective shells 3 are in the storage state, the elastic hook 42 rotates to the fixed state of engaging with the locking protrusion 32 on the protective shell 3. At this time, the limiting plate 5 can rotate to abut against the side of the protective shell 3 facing the mother shell 1 and be accommodated in the clamping groove 15. The elastic snap-fit ​​6 is then engaged in the second groove 152. The outer side of the elastic locking rod 41 away from the limiting plate 5 abuts against one side of the baffle 33. Thus, the limiting plate 5 is used to limit and fix the two protective shells 3 in this state, and the baffle 33 is used to limit the elastic locking rod 41 in this state.

[0038] The implementation principle of this application embodiment is as follows: Assembly state: When the female end component is not connected to an external cable, rotate the two protective shells 3 back to back to the storage state, rotate the limiting plate 5 to accommodate it in the clamping groove 15, the elastic snap-fit ​​6 snaps into the second groove 152 of the clamping groove 15, the elastic hook 42 snaps into the locking protrusion 32 on its own protective shell 3, and one side of the baffle 33 abuts against the outer side of the elastic locking rod 41 at this time to limit the position, thereby fixing the protective shell 3 in this state, while protecting the clamping groove 15 and preventing impurities from adhering.

[0039] Application status: After the external cable is connected to the terminal 7, rotate the two protective shells 3 towards each other to the protective state. Rotate the elastic locking rod 41 so that the elastic hook 42 on one protective shell 3 engages with the locking protrusion 32 on the other protective shell 3, thus locking the two protective shells 3 in this state. Then rotate the limiting plate 5 until it abuts against each other, and the elastic engaging piece 6 engages with the first groove 331 on the baffle 33. At this time, the cable passes through the limiting notch 51, and the elastic pad 52 presses against the outer circumference of the cable, protecting the exposed part of the cable core and improving installation stability.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
