Description

Technical Field

[0001] This utility model relates to the field of wiring harness technology, specifically to a motor wiring harness designed to prevent detachment. Background Technology

[0002] Motor connection harnesses are critical conductive components between motors and control equipment / power supplies, and are widely used in industrial motors, automotive motors, and household appliance motors. Motors often vibrate during operation, and some application environments contain dust and oil. Therefore, connection harnesses must have stable connectors, good sealing protection, and convenient docking operations to ensure stable motor conductivity and extend the harness's lifespan.

[0003] Currently, traditional motor connection harnesses mostly use a single snap-on or plug-in structure for the connectors, without a two-way limit design. The vibration during motor operation can easily cause the connector to fall off, affecting the normal operation of the motor. Some devices are equipped with a threaded sleeve connection to prevent detachment, but assembly personnel sometimes do not tighten it properly. In view of this, we propose a motor connection harness that prevents detachment. Utility Model Content

[0004] The main objective of this invention is to provide a motor connection harness that prevents detachment, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes an anti-detachment motor connection harness, comprising a harness one and a harness two. The harness one has a connector one on its end face, and the harness two has a connector two on its end face. An anti-detachment component is provided on the connector one, the anti-detachment component comprising: A snap-fit ​​rod is fixedly connected to the inner wall of the connector, and an abutment ring is fixedly connected to the outer wall of the snap-fit ​​rod. The guide plug is fixedly connected to the end of the locking rod away from the first abutment ring, and the second abutment ring is fixedly connected to the end of the locking rod near the guide plug. A guide rod is slidably connected to the inner wall of the snap-fit ​​rod, and a movable stop is fixedly connected to the outer wall of the guide rod.

[0006] Preferably, the first connector and the second connector are snapped together, and the snapping rod and the movable stop are elastically connected by a spring.

[0007] Preferably, the snap-fit ​​rod has a storage through hole and a storage groove.

[0008] Preferably, the outer wall of the guide rod is slidably connected to the receiving through hole, and the movable stop is slidably engaged with the receiving groove.

[0009] Preferably, the outer wall of the second connector is fixedly connected to an abutment sleeve, the abutment sleeve is provided with a sealing placement groove, a sealing ring is placed in the sealing placement groove, and the first connector is provided with a sealing mating groove.

[0010] Preferably, an auxiliary rod is fixedly connected to the inner wall of the first connector, and two sets of auxiliary rods are provided, which are distributed at opposite corners of the first connector.

[0011] Preferably, the second connector has a snap-fit ​​through hole and an auxiliary through hole. Both the snap-fit ​​through hole and the auxiliary through hole are provided in two sets. The snap-fit ​​through hole is adapted to the snap-fit ​​rod, and the auxiliary through hole is adapted to the auxiliary rod.

[0012] This utility model provides an anti-detachment motor connection harness. It has the following beneficial effects: (1) The anti-detachment motor connection harness is retracted into the storage groove by pressing the movable stop, and the snap-fit ​​rod can be smoothly inserted into the snap-fit ​​through hole of the connector two. After the insertion is in place, the movable stop is released, and the spring immediately pushes the movable stop to extend, forming a two-way limit of "inner abutment + outer stop" with the abutment ring two of the snap-fit ​​rod. The anti-detachment work is completed at the same time as the snap-fit ​​is completed, without the need for additional operation. The two sets of diagonally distributed snap-fit ​​rods ensure uniform force, and even if the motor vibrates during operation, the connector can be prevented from falling off, solving the cumbersome problem of the traditional structure requiring separate anti-detachment.

[0013] (2) The anti-detachment motor connection harness is connected to the connector one and the connector two through the connector one, so that the sealing placement groove on the abutment sleeve and the sealing mating groove on the connector one are closed, so that the sealing ring can play a sealing effect, preventing dust and oil from entering the interior of the connector, avoiding oxidation or short circuit of the metal terminals, and ensuring conductivity stability.

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model proposes an anti-detachment motor connection harness, including a first harness 1 and a second harness 2. The end face of the first harness 1 is provided with a first connector 3, and the end face of the second harness 2 is provided with a second connector 4. An anti-detachment component 5 is provided on the first connector 3. The anti-detachment component 5 includes a locking rod 51. The locking rod 51 is fixedly connected to the inner wall of the first connector 3, and an abutment ring 52 is fixedly connected to the outer wall of the locking rod 51. A guide plug 53 is fixedly connected to the end of the locking rod 51 away from the abutment ring 52, and an abutment ring 54 is fixedly connected to the end of the locking rod 51 near the guide plug 53. A guide rod 55 is slidably connected to the inner wall of rod 51, and a movable stop 56 is fixedly connected to the outer wall of guide rod 55. Two sets of locking rods 51 are provided, and the two sets of locking rods 51 are distributed at opposite corners of connector 3. The diagonal distribution makes the locking force uniform, avoids the misalignment of the connector, and ensures that the anti-detachment structure on both sides works simultaneously. The movable stop 56 is a rectangular plastic block that matches the size of the storage groove 7. After the locking rod 51 is inserted into place, the movable stop 56 automatically extends out of the storage groove 7 under the action of the spring, and immediately limits it from the outside of connector 4, which cooperates with the abutment ring 54 to form a two-way anti-detachment.

[0020] In this invention, connector 3 and connector 4 are snapped together. The snap-fit ​​rod 51 and the movable stop 56 are elastically connected by a spring. The spring is a compression spring and is built into the inner wall of the snap-fit ​​rod 51. In its natural state, the movable stop 56 is pushed out of the receiving groove 7. Pressing the movable stop 56 causes it to retract, allowing the snap-fit ​​rod 51 to be inserted smoothly. After the snap-fit ​​rod 51 is inserted in place, releasing the movable stop 56 causes the spring to immediately push the movable stop 56 out, simultaneously completing the snap-fit ​​and anti-disengagement limiting. No additional operation is required. The snap-fit ​​rod 51 has a storage through hole 6, which is a cylindrical hole with a diameter that matches the guide rod 55, ensuring smooth sliding of the guide rod 55 and providing a stable sliding basis for the synchronous triggering of the anti-detachment structure. The snap-fit ​​rod 51 has a storage groove 7, which is a rectangular groove that corresponds to the movable stop 56. When the movable stop 56 is retracted, it can be completely stored in the groove without affecting the insertion of the snap-fit ​​rod 51; when it is extended, it is precisely locked on the outside of the connector 2 4 to achieve anti-detachment.

[0021] Furthermore, the outer wall of the guide rod 55 is slidably connected to the receiving through hole 6, and the movable stop 56 is slidably engaged with the receiving groove 7. When the movable stop 56 extends out of the receiving groove 7, it forms a two-way anti-disengagement mechanism of "inner abutment + outer stop" with the second abutment ring 54. When retracted, the snap-fit ​​rod 51 can be smoothly inserted into or pulled out of the snap-fit ​​through hole 13. The operation is smooth and without jamming. The outer wall of the second connector 4 is fixedly connected with an abutment sleeve 8. A sealing placement groove 9 is opened on the abutment sleeve 8. A sealing ring 10 is placed on the sealing placement groove 9. A sealing mating groove 11 is opened on the first connector 3.

[0022] Furthermore, an auxiliary rod 12 is fixedly connected to the inner wall of connector 3. Two sets of auxiliary rods 12 are provided, and the two sets of auxiliary rods 12 are distributed at opposite corners of connector 3. The two sets of auxiliary rods 12 cooperate with the two sets of snap-fit ​​rods 51 to form a four-point support structure, thereby improving the support strength. Connector 4 is provided with snap-fit ​​through holes 13 and auxiliary through holes 14. Both snap-fit ​​through holes 13 and auxiliary through holes 14 are provided in two sets. The diameters of snap-fit ​​through holes 13 and auxiliary through holes 14 are different. Snap-fit ​​through holes 13 are adapted to snap-fit ​​rods 51, and auxiliary through holes 14 are adapted to auxiliary rods 12. The two sets of holes correspond to the two sets of snap-fit ​​rods 51 and auxiliary rods 12, respectively.

[0023] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0024] In use, press the two sets of movable blocks 56 with both hands to retract the movable blocks 56 into the storage groove 7 of the snap-fit ​​rod 51. Align the snap-fit ​​rod 51 of connector 1 3 with the snap-fit ​​through hole 13 of connector 2 4 and the auxiliary rod 12 with the auxiliary through hole 14. Slowly insert until the end face of connector 1 3 is in contact with the abutment sleeve 8 of connector 2 4. At this time, since the movable block 56 is not limited by connector 2 4, the spring immediately pushes the movable block 56 out of the storage groove 7, forming a bidirectional limit with the abutment ring 2 54 of the snap-fit ​​rod 51, and simultaneously completing the snap-fit ​​and anti-disengagement. At the same time, the sealing ring 10 of connector 2 4 is embedded in the sealing groove 11 of connector 1 3 to form a sealing protection. If disassembly is required, press the movable block 56 again to retract it, and pull connector 1 3 in the opposite direction to separate it. No tools are required throughout the process, and the operation is smooth and efficient.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
