Description

Technical Field

[0001] This utility model relates to the field of power transmission line protection technology, and in particular to power transmission line harnesses with protective structures. Background Technology

[0002] A power transmission line harness is a structure used to gather, organize, and protect multiple power transmission lines for easier management and wiring. Harnesses are commonly used in applications requiring efficient and safe power or signal transmission, such as automobiles, power systems, and communication equipment. To effectively isolate the lines, prevent contact with external environments or other conductive materials, and prevent electrical short circuits, power transmission line harnesses with protective structures are necessary.

[0003] Transmission line harnesses can be classified into several types, including power transmission harnesses, signal transmission harnesses, and communication harnesses. These classification methods allow for the selection of the most suitable transmission line harness based on the application scenario to meet specific protection and functional requirements. Signal transmission harnesses are mainly used to transmit low-voltage signals, such as in communication systems and electronic equipment, and require strong anti-interference capabilities to ensure the stability of signal transmission.

[0004] However, existing technologies still have significant problems regarding the connection strength of power transmission line harnesses. Traditional friction connections are relatively fragile under external forces, easily becoming loose or broken due to pulling, especially in industrial or outdoor environments where the connection is highly susceptible to instability caused by accidental vibration or dragging. The lack of targeted protective structures results in insufficient connection strength, failing to effectively cope with varying working environments. This not only reduces equipment lifespan but also causes power outages or equipment malfunctions when the power transmission line harness breaks, severely impacting the reliability of the power transmission system. Therefore, how to introduce higher-strength connection protection structures into power transmission line harnesses to cope with external interference and improve the connection strength of the harnesses has become an urgent problem to be solved. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of parent-child table, which aims to improve the problem that the parent table and child table are easily lost when placed separately in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power transmission line harness with a protective structure, including a cable, one end of which is fixedly connected to a male connector, a housing is fixedly connected to one side of the male connector, the other end of which is fixedly connected to a female connector, the housing is slidably connected inside the female connector, a slot is provided inside the female connector, a locking component is provided on the outer wall of the housing, and a contact component is provided inside both the male connector and the female connector;

[0007] The locking assembly includes a connecting rod, a locking block is fixedly connected to one side of the connecting rod, a protrusion is fixedly connected to one side of the locking block, a groove is formed inside the connecting rod, a stress groove is formed inside the connecting rod, and the locking block and the groove are engaged.

[0008] As a further description of the above technical solution:

[0009] The contact assembly includes a connecting post, one end of which is fixedly connected to the inside of the female connector, and a contact post is slidably connected inside the connecting post, one end of which is fixedly connected to the inside of the male connector.

[0010] As a further description of the above technical solution:

[0011] The housing has an internal mounting groove, and a protrusion is fixedly connected inside the housing.

[0012] As a further description of the above technical solution:

[0013] The housing is provided with a sealing strip inside, and one side of the sealing strip is provided with an inclined surface.

[0014] As a further description of the above technical solution:

[0015] A limiting strip is fixedly connected to the bottom of the sealing strip, and the limiting strip fits into the mounting groove.

[0016] As a further description of the above technical solution:

[0017] The sealing strip has a sealing groove inside, which fits into the convex strip.

[0018] As a further description of the above technical solution:

[0019] The inclined surface fits into the inner wall of the connecting head.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, after the housing is inserted into the connecting female head, the locking block on one side of the connecting rod is embedded into the locking groove on the connecting female head for locking. The connecting rod can deform through the stress groove, thereby improving the connection strength. This solves the problem that when the power transmission harness is connected by friction alone, it is easy to break when it is pulled, thus improving the connection strength of the power transmission harness.

[0022] 2. In this utility model, the sealing groove inside the sealing strip fits into the convex strip to improve the sealing performance and prevent gaps between the sealing strip and the housing. Subsequently, the inclined surface is attached to the inner wall of the connecting female to increase the contact area between the sealing strip and the connecting female, thereby improving the waterproof effect. This solves the problem that gaps exist between the connections of power transmission line harnesses, which can easily lead to short circuits when exposed to dust and rainwater, thus improving the protection of power transmission line harnesses.

[0036] Reference Figures 1-3This utility model provides an embodiment of a power transmission cable harness with a protective structure, including a cable 1. One end of the cable 1 is fixedly connected to a male connector 2, which is used to connect with a female connector 3 to ensure the stability of power transmission. A housing 4 is fixedly connected to one side of the male connector 2. The housing 4 is used to protect the internal components from the influence of the external environment and to provide a certain degree of fixation during connection. The other end of the cable 1 is fixedly connected to a female connector 3. The female connector 3 and the male connector 2 are slidably connected together through the housing 4 to achieve a stable and convenient insertion connection. A slot 6 is provided inside the female connector 3. The slot 6 is used to cooperate with a locking block 7 in the locked state to enhance the firmness of the connection and prevent the connection from falling off. A locking component is provided on the outer wall of the housing 4. The locking component is used to provide an additional locking effect after insertion, further improving the reliability of the connection and avoiding loosening or disconnection due to external pulling. Both the male connector 2 and the female connector 3 are provided with contact components inside. The contact components are used to ensure the effective conduction of current or signals and ensure the stable electrical performance of the power transmission cable harness.

[0037] The locking assembly includes a connecting rod 5, which connects the locking block 7 to the housing 4 and provides elastic deformation during insertion to ensure stability after locking. A locking block 7 is fixedly connected to one side of the connecting rod 5, which engages with the slot 6 when inserted into position to achieve the locking effect. A protrusion 8 is fixedly connected to one side of the locking block 7, providing additional support during locking to ensure the locking block 7 is firmly embedded in the slot 6, enhancing the stability of the connection. A groove 10 is formed inside the connecting rod 5, providing operating space in the locked state for easy unlocking by external force during disassembly. A stress groove 9 is formed inside the connecting rod 5, deforming when the locking block 7 engages with the slot 6 to achieve a smooth locking and releasing process. After the locking block 7 engages with the slot 6, it effectively prevents loosening of the connection and ensures connection stability. The contact assembly includes a connecting post 18, which maintains good contact with the contact post 11 during insertion to ensure stable power transmission. One end of the connecting post 18 is fixedly connected inside the female connector 3. The fixing function of the connecting post 18 ensures stability during connection and use, and avoids poor contact. A contact post 11 is slidably connected inside the connecting post 18. The contact post 11 is used to achieve sliding contact with the connecting post 18, providing flexibility while ensuring current conduction, and avoiding unstable electrical connections due to vibration or external forces. One end of the contact post 11 is fixedly connected inside the male connector 2, ensuring reliable contact during insertion and guaranteeing the normal operation of the power transmission harness.

[0038] Specifically, when connecting cable 1, the male connector 2 is carefully inserted into the inner cavity of the female connector 3 through the housing 4, ensuring alignment. As the insertion depth gradually increases, the contact post 11 on the male connector 2 smoothly enters the connecting post 18 inside the female connector 3, securing the connection both electrically and physically. Once the housing 4 is fully inserted and in place, the locking block 7 on one side of the connecting rod 5 automatically engages with the corresponding slot 6 on the female connector 3, achieving a secure lock. During this process, the connecting rod 5 undergoes slight elastic deformation through its stress groove 9, helping the locking block 7 to smoothly engage with the slot 6, making the lock more stable and reliable. This significantly improves the connection strength between the male connector 2 and the female connector 3, preventing loosening or poor contact during use. When disassembly is required, the operator simply applies gentle force, using the groove 10 to push the female connector 3 outwards, allowing the locking block 7 to disengage from the slot 6 for quick disassembly. This structural design not only facilitates the connection and disassembly process but also ensures the overall connection's robustness and reliability.

[0039] Reference Figures 4-6 The housing 4 has an internal mounting groove 16, which defines the installation position of the sealing strip 12 to prevent it from moving or shifting during use, ensuring the stability of the sealing effect. A protruding strip 17 is fixedly connected inside the housing 4, engaging with the sealing groove 15 of the sealing strip 12 to form a tight connection, further improving the installation stability of the sealing strip 12 and preventing it from falling off. The sealing strip 12 provides a seal during connection, preventing dust, moisture, and other external impurities from entering, thus improving the protection performance of the power transmission harness. A bevel 13 is provided on one side of the sealing strip 12, which ensures a tight fit between the sealing strip 12 and the inner wall of the connecting female 3 when they mate, increasing the contact area and further improving the sealing effect. The bottom of the sealing strip 12 is fixedly connected to... A limiting strip 14 is provided, which is used to fit into the mounting groove 16, so that the sealing strip 12 is kept stable in the mounting groove 16 and the position displacement caused by external pressure or vibration is avoided. A sealing groove 15 is provided inside the sealing strip 12, which is used to fit into the protrusion 17, so as to form a tighter fit between the sealing strip 12 and the housing 4, preventing gaps between the sealing strip 12 and the housing 4, ensuring the reliability of the sealing performance. After the sealing groove 15 fits into the protrusion 17, it can further improve the stability of the sealing strip 12 inside the housing 4, effectively preventing the sealing strip 12 from loosening or shifting, and ensuring that the sealing effect is not affected by the outside. The inclined surface 13 fits against the inner wall of the connecting female head 3, so that the sealing strip 12 can fully cover the contact area when connected, preventing dust, moisture and other substances from entering, improving the protection effect of the power transmission harness, and extending the service life of the equipment.

[0040] Specifically, during the insertion of the housing 4 into the connecting female 3, the precision bevel 13 of the outer wall of the sealing strip 12 tightly adheres to the inner wall surface of the connecting female 3, thereby achieving a high degree of sealing. This fitting design not only effectively prevents the intrusion of external dust, moisture, and other impurities, but also significantly increases the contact area between the sealing strip 12 and the connecting female 3, thus enhancing the sealing strength. The sealing strip 12 is securely embedded in the mounting groove 16 by the limiting strip 14, ensuring its position is fixed and not easily loosened. Simultaneously, the sealing strip 12 has a dedicated sealing groove 15 inside. The sealing groove 15 and the protrusion 17 inside the housing 4 fit together precisely, thereby further improving the airtightness between the sealing strip 12 and the housing 4 and effectively preventing any gaps between them. In addition, the design of the inclined surface 13 closely adhering to the inner wall of the connecting female 3 allows the sealing strip 12 to form a larger contact area when it is in contact with the connecting female 3, ensuring that the cable 1 has a high degree of protection and reliability in the connected state. This structural design not only improves the protection level of the entire connection device, but also ensures the sealing performance during long-term use, guaranteeing the safety and durability of the equipment.

[0041] Working principle: When using this protective power transmission cable harness, firstly, when connecting cable 1, the male connector 2 is inserted into the female connector 3 through the housing 4. Then, the contact post 11 is inserted into the connecting post 18 for connection. After the housing 4 is fully inserted into the female connector 3, the locking block 7 on one side of the connecting rod 5 is inserted into the slot 6 on the female connector 3 for locking. The connecting rod 5 can deform through the stress groove 9, thereby allowing the locking block 7 to smoothly embed into the slot 6, thus improving the connection strength when the male connector 2 and the female connector 3 are connected. When disassembly is required, simply use the groove 10 to remove the female connector. Simply pry the head 3 outward to separate the locking block 7 from the locking groove 6. At the same time, when the housing 4 is inserted into the connector 3, the inclined surface 13 of the outer wall of the sealing strip 12 fits against the inner wall of the connector 3 to seal. The sealing strip 12 is connected and installed by embedding it into the mounting groove 16 through the limiting strip 14. At the same time, the sealing groove 15 opened inside the sealing strip 12 fits into the protrusion 17 to improve the sealing performance and prevent gaps between the sealing strip 12 and the housing 4. Subsequently, the inclined surface 13 fits against the inner wall of the connector 3 to increase the contact area between the sealing strip 12 and the connector 3, thereby improving the protection of the cable 1 during connection.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
