Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a double-locking wire harness connector. Background Technology

[0002] In the field of mechanical engineering, wire harness connectors are key components for achieving circuit connections, and their performance directly affects the stable operation of the entire system. Currently, traditional wire harness connectors generally employ a single locking structure. This structure is prone to loosening under complex operating conditions such as vibration and impact, leading to poor circuit contact and, in severe cases, even equipment failure, causing unnecessary losses. Simultaneously, the sealing performance of existing connectors is mostly inadequate, allowing external dust, moisture, and other impurities to easily penetrate, corroding conductive components, shortening the connector's lifespan, and affecting normal equipment operation. Furthermore, the connection operation of some connectors is cumbersome, with low installation efficiency, and the locking components are prone to wear during long-term use, further reducing connection reliability. To effectively solve these problems and meet the demands for high stability, high sealing performance, and convenient operation in practical applications, it is particularly necessary to develop a wire harness connector with dual locking functions, excellent sealing performance, and efficient installation.

[0003] The patent publication number "CN222826736U" discloses "This utility model belongs to the field of wire harness docking structure technology, specifically a wire harness connector, including a male connector, a female connector inserted into the male connector, a plug fixedly provided on the side of the female connector near the male connector, and a locking mechanism fixedly provided on both opposite sides of the male connector in a mirror image. The locking mechanism includes a fixed cylinder, a movable rod slidably passing through the center of the top of the fixed cylinder, and a locking pin fixedly provided at the other end of the movable rod. The locking pin slidably passes through a hole opened on the male connector and is disposed inside the male connector. A first spring is fixedly provided between the locking pin and the opposite side of the inner wall of the fixed cylinder. Positioning strips are fixedly provided on both sides of the plug, and a locking groove is opened on one side of the positioning strip. The locking pin is inserted into the locking groove. Through the cooperation of the locking mechanism, the male connector and the female connector are limited and fixed, improving the docking firmness and effectively preventing the wire from being short-circuited and disconnected due to external force."

[0004] While existing double-locking wire harness connectors improve mating stability to some extent through locking mechanisms, they still have several shortcomings. In terms of locking structure, they rely solely on a single locking mechanism—a locking pin inserted into a locking groove. This single locking method is prone to loosening and dislodging under long-term vibration or strong external forces, resulting in insufficient locking stability and failing to meet the requirements for high-stability connections. Regarding sealing performance, the existing equipment lacks a dedicated sealing structure, allowing external dust, moisture, and other impurities to easily penetrate the connector, corroding internal conductive components, affecting the connector's lifespan and conductivity, and making it unsuitable for dusty, humid, and other complex environments. Utility Model Content

[0005] The purpose of this invention is to provide a double-locking wire harness connector, which solves the problem of poor locking stability caused by existing equipment relying on only a single locking mechanism. This invention achieves the first level of locking through the cooperation of an upper slider, a lower slider, a threaded rod, and a rotating motor. A second level of locking is achieved by a telescopic motor driving a fixed rod to insert into the upper slider's insertion hole. This double-locking structure significantly improves locking stability and effectively prevents loosening and disengagement under long-term vibration or strong external forces. Regarding sealing performance, existing equipment lacks a dedicated sealing structure and is susceptible to impurities. This invention uses a sealing plate of the female connector that slides inside the sealing ring of the male connector, forming an effective sealing barrier to block dust, moisture, and other impurities, solving the problem of poor sealing performance in existing equipment. Furthermore, the motor-driven automation improves installation and disassembly efficiency compared to the cumbersome operation of existing equipment relying on springs. The multi-directional collaborative locking structure enhances the overall connection strength and further optimizes performance.

[0006] To achieve the above objectives, this utility model provides a double-locking wire harness connector, including a male connector and a female connector;

[0007] It also includes grooves on both the upper and lower sides of the male connector;

[0008] A slide rod is fixedly installed on the upper inner side of the male connector, an upper slide block is slidably installed on the outer side of the slide rod, a threaded rod is rotatably installed on the lower inner side of the male connector, a threaded hole is slidably installed on the outer side of the slide groove, the threaded rod is screwed through the inside of the threaded hole, a rotary motor is fixedly installed on the outer side of the male connector, and the output shaft of the rotary motor passes through the male connector and is fixedly connected to the threaded rod.

[0009] Both the upper and lower sliders have threaded holes inside. The top of the upper slider has an insertion hole. A telescopic motor is fixedly installed on the top of the male connector. The output end of the telescopic motor passes through the male connector and is fixedly installed with a fixing rod. The fixing rod can be inserted into the insertion hole.

[0010] The female connector has support plates fixedly installed on both the upper and lower sides, and bolts are rotatably installed inside the support plates, with the bolts screwed into the threaded holes.

[0011] The male connector has a plug fixedly installed inside, while the female connector has a slot inside, into which the plug is inserted.

[0012] The female connector has a cover plate fixedly installed on its side, and a sealing plate fixedly installed on the inside of the cover plate. The male connector has a sealing ring fixedly installed on its side, and the sealing plate is slidably installed on the inside of the sealing ring.

[0013] The male connector has a second connecting wire fixedly installed on its outer side, and the female connector has a first connecting wire fixedly installed on its outer side.

[0014] This utility model discloses a double-locking wire harness connector. Through the sliding grooves on the upper and lower sides of the male connector and the sliding rod fixed to the upper inner side, a stable and precise sliding track is provided for the upper and lower sliders. The sliding grooves restrict the sliding direction of the sliders, preventing them from deviating, while the sliding rod provides stable support for the upper slider, ensuring that neither shakes during movement and that they slide smoothly along a predetermined path, laying a good foundation for subsequent locking actions. A threaded rod rotatably mounted on the lower inner side of the male connector is connected to the output shaft of a rotating motor fixed on the outer side. When the rotating motor starts, its output shaft stably transmits rotational force to the threaded rod, causing it to rotate at a uniform speed. Due to the engagement of the threaded rod with the internal threaded structure of the lower slider, the rotation of the threaded rod is converted into the lower slider sliding linearly along the sliding groove. Simultaneously, the upper slider moves synchronously, allowing the upper and lower sliders to work together to accurately reach the required locking position. This provides reliable and strong power support for the connector's locking, effectively improving the accuracy and stability of the locking process and ensuring a tight and secure fit between the male and female connectors.

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figure 1-5 .

[0024] A double-locking wire harness connector, comprising a male connector 1 and a female connector 2;

[0025] It also includes that the male connector 1 has grooves 16 on both the upper and lower sides inside.

[0026] A slide rod 14 is fixedly installed on the upper inner side of the male connector 1, and an upper slide block 8 is slidably installed on the outer side of the slide rod 14. A threaded rod 11 is rotatably installed on the lower inner side of the male connector 1. A threaded hole 10 is slidably installed on the outer side of the slide groove 16. The threaded rod 11 is screwed through the interior of the threaded hole 10. A rotary motor 21 is fixedly installed on the outer side of the male connector 1. The output shaft of the rotary motor 21 passes through the male connector 1 and is fixedly connected to the threaded rod 11.

[0027] First, the male connector 1 and female connector 2 are the core components of this double-locking wire harness connector. The male connector 1 has grooves 16 on both its upper and lower sides, providing a track for the sliding of subsequent components. A slide rod 14 is fixedly installed on the upper inner side of the male connector 1, and an upper slider 8 is slidably installed on the outer side of the slide rod 14, allowing it to slide smoothly along the slide rod 14. A threaded rod 11 is rotatably installed on the lower inner side of the male connector 1, and a lower slider 12 is slidably installed on the outer side of the groove 16. A threaded hole 10 is opened inside the lower slider 12, and the threaded rod 11 is screwed through the inside of this threaded hole 10. A rotary motor 21 is fixedly installed on the outer side of the male connector 1, and the output shaft of the rotary motor 21 passes through the male connector 1 and is fixedly connected to the threaded rod 11. When the rotating motor 21 starts, its output shaft drives the threaded rod 11 to rotate. Since the threaded rod 11 is screwed into the threaded hole 10 of the lower slider 12, and the lower slider 12 is restricted by the slide groove 16 to slide only in a straight line, the rotation of the threaded rod 11 will be converted into the sliding of the lower slider 12 along the slide groove 16. At the same time, the upper slider 8 can slide synchronously on the slide rod 14. By adjusting the positions of the upper slider 8 and the lower slider 12, the basic structure and power drive for locking the connector are provided, ensuring the accuracy and stability of the locking process.

[0028] Furthermore, both the upper slider 8 and the lower slider 12 have threaded holes 10 inside, which can be screwed and fixed to external components. The top of the upper slider 8 has an insertion hole 9, and a telescopic motor 5 is fixedly installed on the top of the male connector 1. The output end of the telescopic motor 5 passes through the male connector 1 and is fixedly mounted with a fixing rod 13, which can be inserted into the insertion hole 9. When it is necessary to lock the position of the upper slider 8, the telescopic motor 5 is activated, and its output end extends, driving the fixing rod 13 to insert into the insertion hole 9, thereby restricting the sliding of the upper slider 8; when unlocking, the output end of the telescopic motor 5 retracts, the fixing rod 13 is pulled out of the insertion hole 9, and the upper slider 8 regains its sliding ability. This structure, through mechanical insertion, provides secondary fixation after the upper slider 8 is adjusted to the correct position, preventing displacement of the upper slider 8 under external forces such as vibration, and significantly enhancing the stability of the connector locking.

[0029] Furthermore, support plates 17 are fixedly installed on both the upper and lower sides of the female connector 2, providing stable support for the installation of bolts 19. Bolts 19 are rotatably installed inside the support plates 17, and bolts 19 can be screwed into the threaded holes 10 inside the upper slider 8 and lower slider 12. When the male connector 1 is connected to the female connector 2, the upper slider 8 and lower slider 12 are first adjusted to the position corresponding to the support plate 17, and then the bolts 19 are rotated to gradually screw them into the threaded holes 10 of the upper slider 8 and lower slider 12. Through the screwing action of the bolts 19 and the threaded holes 10, the initial fixed connection between the male connector 1 and the female connector 2 is achieved. This connection method is not only easy to operate, but also ensures the firmness of the connection through the self-locking characteristics of the threads, effectively preventing loosening after connection.

[0030] Furthermore, a plug 15 is fixedly installed inside the male connector 1, and a slot 18 is opened inside the female connector 2, allowing the plug 15 to be precisely inserted into the slot 18. During the mating process of the male connector 1 and female connector 2, as they gradually approach each other, the plug 15 first aligns with the slot 18. As the mating progresses, the plug 15 smoothly inserts into the slot 18, and the tight fit between the two achieves electrical connection. The plug 15 and slot 18 adopt a high-precision dimensional design to ensure good contact and reduce contact resistance. They are key connection points for signal or power transmission in the wire harness, ensuring the stability and reliability of current or signal during transmission and reducing signal attenuation or power loss.

[0031] Furthermore, a cover plate 3 is fixedly installed on the side of the female connector 2, and a sealing plate 20 is fixedly installed on the inner side of the cover plate 3. A sealing ring 7 is fixedly installed on the side of the male connector 1. The sealing ring 7 is made of elastic material, and the sealing plate 20 is slidably installed on the inner side of the sealing ring 7. When the male connector 1 is connected to the female connector 2, as the two approach each other, the sealing plate 20 will gradually slide into the inner side of the sealing ring 7. Due to the elasticity of the sealing ring 7, it will fit tightly with the sealing plate 20, forming a sealing barrier. This sealing structure can effectively prevent dust, moisture, oil and other impurities from entering the connector, avoiding impurities adhering to conductive parts such as the plug 15 and the slot 18, causing poor contact or short circuits. At the same time, it prevents internal components from being corroded, significantly improving the service life of the connector and its reliability in harsh environments.

[0032] Furthermore, a second connecting wire 6 is fixedly installed on the outside of the male connector 1, and a first connecting wire 4 is fixedly installed on the outside of the female connector 2. One end of the second connecting wire 6 is connected to the conductive structure inside the male connector 1, and the other end is used to connect to an external wire harness; one end of the first connecting wire 4 is connected to the conductive structure inside the female connector 2, and the other end is also connected to an external wire harness. When the male connector 1 and the female connector 2 are mated, the plug 15 and the slot 18 are connected, so that the first connecting wire 4 and the second connecting wire 6 form a complete conductive path through the connector. External signals or power can be transmitted to the female connector 2 through the first connecting wire 4, and then transmitted to the male connector 1 through the plug 15 and the slot 18, and finally output by the second connecting wire 6. This achieves effective connection between the wire harnesses, ensuring the normal operation of the entire circuit system. Moreover, the connecting wires and connectors are fixed with high-strength insulating material to ensure safety during use.

[0033] Furthermore, to ensure the stability of the entire connector during operation, all components are fixed using high-strength bolts or welding. For example, the connections between the slide rod 14 and the male connector 1, the rotary motor 21 and the male connector 1, and the support plate 17 and the female connector 2 have all undergone rigorous strength testing and can withstand significant tensile forces and vibrations. Simultaneously, an anti-oxidation layer is plated on the surfaces of the plug 15 and the slot 18 to reduce oxidation and corrosion after long-term use, ensuring the stability of conductivity. In addition, both the rotary motor 21 and the telescopic motor 5 are low-power, high-torque models, ensuring driving performance while reducing energy consumption, making the connector suitable for various working scenarios.

[0034] Complete work process:

[0035] This double-locking wire harness connector achieves a stable connection through the coordinated cooperation of male connector 1 and female connector 2. The upper and lower sliding grooves 16 inside the male connector 1 guide the upper slider 8 (sliding along the inner upper fixed sliding rod 14) and the lower slider 12 (sliding driven by the threaded rod 11 driven by the outer rotating motor 21) to adjust their positions. When the slider is aligned with the upper and lower support plates 17 of the female connector 2, the bolts 19 on the support plates 17 are screwed into the threaded holes 10 inside the slider to complete the initial locking. At the same time, the telescopic motor 5 at the top of the male connector 1 drives the fixing rod 13 to insert into the insertion hole 9 at the top of the upper slider 8 to form a secondary locking, thus doubly ensuring the stability of the connection. During docking, the plug 15 inside the male connector 1 and the slot 18 inside the female connector 2 are precisely inserted to achieve electrical conduction. The sealing plate 20 inside the side cover plate 3 of the female connector 2 and the sealing ring 7 on the side of the male connector 1 fit tightly to block impurities. The external wire harness completes signal or power transmission through the first connecting line 4 outside the female connector 2 and the second connecting line 6 outside the male connector 1, ensuring the reliability and safety of the overall connection.
