Description

Technical Field

[0001] The present invention relates to the technical field of wire harness electric control connection components, and specifically relates to an automotive wire harness electric control connection component. Background Art

[0002] Automotive wire harness electric control connection components are key components in automotive electrical systems, undertaking the important tasks of signal transmission and power distribution. It mainly consists of connectors, terminals, cable protective sleeves, etc., and can accurately and reliably connect various electronic control units (ECUs) in the vehicle with devices such as sensors and actuators. This component has excellent electrical performance, mechanical strength, and environmental resistance, and can work stably under complex working conditions such as high temperature, vibration, and humidity. The rationality of its design and manufacturing accuracy are directly related to the safety, comfort, and intelligent level of the vehicle, and are important supports for the development of modern automotive technology.

[0003] The patent document with Chinese Publication No. CN221900316U discloses a new energy vehicle wire harness electric control connector assembly, including a first connector. A second connector is arranged on one side of the first connector, an adjusting mechanism is arranged on one side of the first connector, and a protection mechanism is arranged inside the first connector; the adjusting mechanism includes a protective shell, an outer shell is arranged at the bottom of the protective shell, a rotating shaft is arranged on one side of the protective shell, and a connecting rod is fixedly connected to one side of the rotating shaft. By setting the adjusting mechanism, during the moving process, since the first connector is connected to the fixing plate through the protective shell, and the fixing plate is connected to the protective shell through the rotating shaft, the protective shell can rotate. At the same time, by arranging moving blocks on both sides of the protective shell and arranging limiting grooves inside the outer shell, the protective shell can move on the outer shell through the moving blocks, thereby adjusting the first connector, facilitating the adjustment of the connection angle, facilitating installation, and improving the installation efficiency.

[0018] A column is longitudinally fixed on the top of the piston rod, a limiting block capable of moving along its central axis is installed at the top of the column, and a second return spring for pushing it to extend out of the inside of the mounting chamber is installed inside the limiting block.

[0019] As a technical solution of the present invention, a temperature probe rod capable of contacting the surface of the plug is fixed at the working end of the controller.

[0020] As a technical solution of the present invention, a plurality of outward expansion components are fixedly arranged at equal intervals on the outer part of the mounting rod, and the working ends of the outward expansion components can be inserted into the inner wall of the insertion tube to contact or separate.

[0021] As a technical solution of the present invention, a plurality of mounting grooves are equidistantly arranged around the central axis direction of the plug;

[0022] A plurality of top blocks capable of being installed inside the mounting grooves are hinged at equal intervals around the central axis of the outer part of the outward expansion component.

[0023] As a technical solution of the present invention, a limiting rod for limiting is horizontally arranged inside the mounting groove;

[0024] A kidney-shaped hole capable of being adapted to the limiting rod is arranged on the top block.

[0025] As a technical solution of the present invention, a jack capable of communicating with the installation chamber is arranged on one side of the male socket close to the female socket;

[0030] As a technical solution of the present invention, a first return spring for pushing the floating rod to move upward is installed on the outer part of the floating rod.

[0031] The beneficial effects of the present invention compared with the prior art are:

[0032] 1. In this application, when the plug is inserted into the insertion tube, the insertion tube squeezes the pressing rod at one end of the mounting rod, and the pressing rod is pushed by the extrusion to drive the mounting rod to move. When the mounting rod moves, it can drive the outward expansion components installed on its outer part to contact the inner wall of the insertion tube, effectively ensuring the stable connection between the plug and the insertion tube. The problem of unstable connection between the plug and the insertion tube is solved.

[0033] 2. In this application, the kerosene inside the liquid storage chamber is heated by a heating rod. When the kerosene is heated, the thermal motion of its molecules intensifies, the intermolecular distance increases, resulting in volume expansion. This causes the kerosene to enter the piston chamber, increasing the pressure inside the piston chamber and pushing the piston rod to move horizontally. So that the end of the piston rod away from the piston chamber can eject the female socket from inside the male socket, thereby realizing the automatic separation of the male socket and the female socket.

[0034] 3. This application uses the piston rod to drive the inclined surface arranged at the bottom to gradually approach the floating rod, so that the inclined surface squeezes the top of the floating rod. At this time, the floating rod will drive the abutting block to gradually approach the insertion tube until the abutting block contacts the insertion tube, thereby fixing the insertion tube with the abutting block.

Detailed implementation mode

[0050] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0051] See Figures 1 - 14 As shown, an automotive wire harness electronic control connection assembly includes a male socket 1, a rear seat 3 provided at one end of the male socket 1, a mounting seat 31 horizontally provided at the center on one side of the rear seat 3 and capable of extending into the male socket 1, a plug 7 installed inside the mounting seat 31, and a temperature monitoring mechanism 4 provided on both sides of the mounting seat 31 for detecting the surface temperature of the plug 7. A fourth return spring 95 is installed inside the plug 7;

[0052] An inner support mechanism 9 capable of moving along its central axis is installed inside the plug 7. The inner support mechanism 9 includes a mounting rod 90, and outward expansion assemblies 91 capable of expanding outward are equidistantly fixed on the outside of the mounting rod 90;

[0053] A pressing rod 93 is installed inside one end of the mounting rod 90;

[0054] A third return spring 94 for pushing the pressing rod 93 to extend outward is further provided inside one end of the mounting rod 90;

[0055] A female socket 2 is provided on one side of the male socket 1, and an insertion tube 23 capable of inserting the plug 7 is provided at the center of the female socket 2.

[0056] When the plug 7 is inserted into the inner part of the socket tube 23, the socket tube 23 will squeeze the pressing rod 93 installed at one end of the mounting rod 90, causing the pressing rod 93 to move along the central axis of the mounting rod 90. At this time, the squeezing force received by the pressing rod 93 will act on the fourth return spring 95 synchronously through the mounting rod 90, causing the fourth return spring 95 to push the mounting rod 90 to move along the central axis direction of the plug 7. At the same time, the third return spring 94 and the fourth return spring 95 will gradually accumulate potential energy when being squeezed. When the mounting rod 90 moves, it can drive the outer expansion assembly 91 installed outside it to contact the inner wall of the socket tube 23, effectively ensuring the stable connection between the plug 7 and the socket tube 23. When the plug 7 is pulled out from the inner part of the socket tube 23, at this time, the squeezing forces received by the pressing rod 93 and the mounting rod 90 disappear, causing the potential energy accumulated by the fourth return spring 95 installed inside the plug 7 and the third return spring 94 installed inside the mounting rod 90 to be released, causing the third return spring 94 to push the pressing rod 93 out of the inner part of the mounting rod 90. At the same time, the fourth return spring 95 pushes the mounting rod 90 to move in the reverse direction. When the mounting rod 90 moves in the reverse direction, the outer expansion assembly 91 installed outside the mounting rod 90 is retracted and separated from the socket tube 23.

[0057] See Figure 3 、 Figure 6 and Figure 14 As shown in

[0058] Inside the male socket 1 near one side of the rear seat 3, liquid storage chambers 11 for storing kerosene are symmetrically opened, and the liquid storage chambers 11 can communicate with one end of the piston chamber 12;

[0059] Inside the liquid storage chamber 11, a heating rod 45 for heating the kerosene inside it is provided, and one end of the heating rod 45 can be electrically connected to the relay 42;

[0060] Inside the piston chamber 12, a piston rod 8 capable of ejecting the female socket 2 is horizontally arranged.

[0061] When the temperature monitoring mechanism 4 detects that the surface temperature of the plug 7 is higher than the safe value range, the controller 41 controls the relay 42 to start, so that the relay 42 energizes the heating rod 45. At this time, the heating rod 45 heats the kerosene inside the liquid storage chamber 11. When the kerosene is heated, the molecular thermal motion of the kerosene intensifies, the molecular spacing increases, resulting in volume expansion. This causes the kerosene to enter the piston chamber 12. When the kerosene enters the piston chamber 12, the pressure inside the piston chamber 12 increases and pushes the piston rod 8 to move horizontally, so that one end of the piston rod 8 away from the piston chamber 12 can extend outwards from the inside of the installation chamber 16. At this time, one end of the piston rod 8 away from the piston chamber 12 will push the female socket 2 out of the male socket 1. Thus, the automatic separation of the male socket 1 and the female socket 2 is realized.

[0062] See Figure 3 、 Figure 11 and Figure 12 As shown, on both sides of the female socket 2, there are provided limit plates 21, and on the side of one end of the limit plate 21 away from the female socket 2, there is provided a card slot 22;

[0063] Inside the male socket 1, on the side close to the female socket 2, installation chambers 16 are symmetrically provided;

[0064] On both sides of the male socket 1, there are provided relief grooves 15 that can communicate with the inside of the installation chamber 16;

[0065] Vertically fixed on the top of the piston rod 8 is a column 81, and at the top of the column 81, there is installed a limit block 811 that can move along its central axis. Inside the limit block 811, there is installed a second return spring 812 for pushing it to extend out of the inside of the installation chamber 16.

[0066] When the piston rod 8 performs the ejection task, the piston rod 8 drives the limit block 811 to move synchronously through the column 81. The side of the top of the limit block 811 will contact the side of the relief groove 15. At this time, the relief groove 15 will squeeze the limit block 811, causing the limit block 811 to move downward along the central axis of the column 81. When the female socket 2 is docked with the male socket 1, one side of the female socket 2 will contact one end of the piston rod 8 away from the piston chamber 12, causing the female socket 2 to push the piston rod 8 into the piston chamber 12. At the same time, the piston rod 8 can drive the limit block 811 to gradually approach the relief groove 15 through the column 81. When the top of the limit block 811 is at the bottom of the relief groove 15, the second return spring 812 installed inside the limit block 811 will push the limit block 811 upward, causing the limit block 811 to penetrate the relief groove 15 and extend out of the inside of the installation chamber 16. At this time, the card slots 22 provided on the sides of the limit plates 21 on both sides of the female socket 2 are exactly at the top of the relief groove 15. When the limit block 811 extends out of the relief groove 15, it is exactly clamped inside the card slot 22, effectively fixing the female socket 2.

[0067] See Figure 14As shown, a temperature probe rod 43 that can contact the surface of the plug 7 is fixed to the working end of the controller 41.

[0068] In order to accurately detect the temperature of the surface of the plug 7, by setting the temperature probe rod 43 on one side of the controller 41, the working end of the temperature probe rod 43 can contact the surface of the plug 7, enabling the temperature probe rod 43 to effectively monitor the temperature of the plug 7 in real time and effectively avoiding damage caused by excessive temperature during the operation of the electronic control components.

[0069] See Figure 3 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 14 As shown, a number of outward expansion components 91 are equidistantly fixed to the outside of the mounting rod 90, and the working ends of the outward expansion components 91 can be inserted into and contact or separate from the inner wall of the insertion tube 23.

[0070] By setting a plurality of outward expansion components 91 on the outside of the mounting rod 90, when the outward expansion components 91 expand, the working ends of the outward expansion components 91 can contact the insertion tube 23 simultaneously. The plug 7 is connected to the insertion tube 23 at multiple points through the inner support mechanism 9 and the outward expansion components 91, ensuring the stability of the connection between the plug 7 and the insertion tube 23.

[0071] See Figure 10 As shown, a number of mounting grooves 71 are equidistantly formed around the central axis direction of the plug 7;

[0072] A number of top blocks 92 that can be installed inside the mounting grooves 71 are equidistantly hinged around the central axis of the outside of the outward expansion component 91.

[0073] When the outward expansion component 91 expands, the top blocks 92 hinged on the outward expansion component 91 extend outward through the mounting grooves 71. At this time, one end of the top block 92 can contact the insertion tube 23, thus achieving power-on. When the outward expansion component 91 contracts, the top blocks 92 hinged on the outward expansion component 91 will enter the inside of the plug 7 through the mounting grooves 71. At this time, one end of the top block 92 is separated from the insertion tube 23, thus achieving power-off.

[0074] See Figure 9 and Figure 10 As shown, a limiting rod 72 for limiting is horizontally arranged inside the mounting groove 71;

[0075] A kidney-shaped hole 921 that can be adapted to the limiting rod 72 is formed on the top block 92.

[0076] By providing a kidney-shaped hole 921 on the top block 92 and then installing the top block 92 on the limit rod 72 through the kidney-shaped hole 921. When the outward expansion assembly 91 drives the top block 92 to move, the limit rod 72 can move within the kidney-shaped hole 921. At this time, the top block 92 and the kidney-shaped hole 921 cooperate to rotate around the central axis of the limit rod 72.

[0077] See Figure 3 and Figure 5 As shown, on the side of the male socket 1 close to the female socket 2, there is a jack 14 that can communicate with the installation chamber 16;

[0078] One end of the piston rod 8 far from the piston chamber 12 can be adapted to the jack 14.

[0079] To ensure the stability of the piston rod 8, by providing a jack 14 on the side of the male socket 1 close to the female socket 2 and then installing one end of the piston rod 8 far from the piston chamber 12 inside the jack 14, the piston rod 8 can move along the central axis direction of the jack 14, thus preventing the piston rod 8 from rotating during movement.

[0080] See Figure 3 、 Figure 4 、 Figure 11 and 12 As shown, inside the male socket 1 there is a plugging cavity 13;

[0081] The bottom of the piston rod 8 is provided with an inclined surface 82;

[0082] Longitudinally provided at the bottom of the piston rod 8 is a floating rod 61 that can extend into the plugging cavity 13. One end of the floating rod 61 far from the piston rod 8 is fixed with a pressing block 63 that can clamp on the surface of the plug tube 23.

[0083] When the female socket 2 pushes the piston rod 8, the piston rod 8 will drive the inclined surface 82 provided at the bottom to gradually approach the floating rod 61, causing the inclined surface 82 to squeeze the top of the floating rod 61. At this time, the floating rod 61 will drive the pressing block 63 to gradually approach the plug tube 23 until the pressing block 63 contacts the plug tube 23, so that the pressing block 63 fixes the plug tube 23.

[0084] See Figure 3 、 Figure 4 、 Figure 11 and 12 As shown, outside the floating rod 61, there is a first return spring 62 for pushing the floating rod 61 upward.

[0085] When the extrusion force on the floating rod 61 disappears, the first return spring 62 will push the floating rod 61 away from the plug tube 23, causing the floating rod 61 to drive the pressing block 63 to separate from the plug tube 23.

[0086] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
