Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal technology, and in particular to a wire harness terminal sheath assembly. Background Technology

[0002] In modern electrical systems, wire harness terminals are key components for electrical connections, serving as both electrical connections and mechanical fixation between wires and electrical equipment. They are connected to wires via crimping or welding, and then interface with other electrical components to achieve circuit conduction and signal transmission. Wire harness terminal sheath assemblies are supporting devices that protect and manage wire harness terminals. They centrally house the wire harness terminals through a housing and are equipped with limiting and fixing structures to prevent the wire harness terminals from being damaged by external physical forces, dust intrusion, and moisture corrosion, while also achieving orderly organization and fixation of the wire harness.

[0003] A search revealed Chinese patent publication number CN210489329U, which discloses a sheath structure for wire harness terminals. The sheath body includes a first half-sleeve and a second half-sleeve that fits into the first half-sleeve. The lower edge of the first half-sleeve is fixed to the lower edge of the second half-sleeve, and a connecting strap is provided at the top of the first half-sleeve. A fitting groove is formed on the outer surface of the top of the second half-sleeve. One end of the connecting strap is fixed to the top of the first half-sleeve, and the other end is fixed with a fitting body embedded in the fitting groove. This invention has the following advantages and effects: the sheath structure is easy to install on wire harness terminals, simplifying the terminal assembly process and improving the installation efficiency of wire terminal sheaths. However, in actual use, this device can only be used on one terminal at a time. When multiple terminals need protection, they must be installed one by one, which is cumbersome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wire harness terminal sheath assembly, which aims to improve the problem that the existing device can only be used for one terminal, but when multiple terminals need to be protected, they need to be installed one by one, which is cumbersome to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire harness terminal sheath assembly, comprising a housing, wherein multiple wire terminals are fixedly connected inside the housing, and a fixing plate is fixedly connected to both the upper and lower sides of the front end of the housing. Multiple grooves are equidistantly opened on the top of the upper fixing plate, and multiple limiting holes are equidistantly opened on the rear side of the lower fixing plate. Limiting rods are slidably connected inside each of the multiple grooves, and sliding grooves are opened at the bottom of the rear side of each of the multiple limiting rods. Springs are fixedly connected to one side of each of the multiple sliding grooves, and limiting blocks are fixedly connected to the rear ends of each of the multiple springs. Top plates are fixedly connected to the tops of each of the multiple limiting rods, and a limiting mechanism is provided on the top of the housing.

[0006] Through the above technical solution: When using the wire harness terminal sleeve assembly, the wire terminals are fixed inside the housing for connecting the wire harness. The fixing plate serves as an important connecting structure. The groove on the top of the upper fixing plate and the limiting hole on the rear side of the lower fixing plate cooperate with each other to achieve a limiting function. When the wire harness needs to be installed, the limiting rod is inserted into the groove. The limiting rod can slide in the groove for easy adjustment of its position. In the sliding groove at the bottom of the rear side of the limiting rod, the spring and the limiting block form an elastic limiting structure. When the spring is in a compressed state, it pushes the limiting block. When the limiting rod moves to the appropriate position, the limiting block can be engaged in the limiting hole, thereby fixing the position of the limiting rod and thus limiting the wire harness. The top plate is fixed to the top of the limiting rod, making it easy for the operator to push or pull the limiting rod, achieving convenient operation during installation and disassembly. When the wire harness needs to be disassembled, the top plate is pulled upward to overcome the spring force, causing the limiting block to disengage from the limiting hole, and the limiting rod can be pulled out of the groove to complete the disassembly step.

[0007] As a further description of the above technical solution:

[0008] The limiting mechanism includes multiple fixing blocks. The bottom of each fixing block is fixedly connected to the top front side of the outer shell. Each fixing block has a moving groove on its rear side and a locking slot on its top. The top inner side of each moving groove is connected to a corresponding locking slot. Each moving groove has a moving block slidably connected inside it. Each moving block has a locking block fixedly connected to its top rear side. Each limiting rod has a fixing groove in its lower rear side.

[0009] The above technical solution works as follows: During installation, the moving block is pushed to move the locking block along the slot. When the limiting rod moves to the appropriate position, the moving block is lifted upwards, and the locking block is released from the slot. The locking block is then moved laterally to embed it into the fixing slot of the limiting rod. The moving block is then lowered, and the locking block is locked into the bottom of the fixing slot. In this way, the limiting rod is fixed, thereby limiting the wire harness. During disassembly, the operation is reversed: first, the moving block is lifted, and the locking block is moved out of the fixing slot. Then, the moving block is pushed back to the slot, which releases the restriction on the limiting rod and completes the disassembly process.

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

[0011] Each of the top plates is fixedly connected to a handle, and each of the handles has a groove on its front side.

[0012] The above technical solution provides an application point for operators to manually pull or push the limit rod to complete the installation and disassembly of the wiring harness.

[0013] As a further description of the above technical solution:

[0014] A handle is fixedly connected to the rear side of the housing, and the outer wall of the handle has a smooth design.

[0015] The above technical solution allows for easy handling and movement of the entire wire harness terminal sheath assembly by the staff using the handle on the back of the housing.

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

[0017] The inner left and right sides of the outer casing are provided with sliding grooves, and the left and right sides of the multiple limiting rods are fixedly connected with sliders.

[0018] The above technical solution provides guidance and support for the movement of the limit rod, ensuring that the limit rod remains stable during the sliding process and does not deviate or shake, thereby enhancing the stability and reliability of the limit rod's sliding.

[0019] As a further description of the above technical solution:

[0020] Each of the multiple limiting rods has a limiting groove on its left and right sides, and each of the multiple limiting blocks one has a limiting block two fixedly connected to its front left and right sides.

[0021] The above technical solution restricts the movement direction of the limiting block 1 in the sliding groove, prevents the limiting block 1 from shifting or falling out under the action of the spring, and ensures that the limiting block 1 can be accurately engaged in the limiting hole.

[0022] As a further description of the above technical solution:

[0023] Each of the multiple limiting blocks is slidably connected to the interior of a corresponding sliding groove, and the size of the sliding groove matches that of the limiting block.

[0024] Through the above technical solution: when the limiting rod moves into place, the limiting block one is engaged in the limiting hole under the elastic force of the spring, thus fixing the position of the limiting rod.

[0025] As a further description of the above technical solution:

[0026] The front ends of the multiple movable blocks are slidably connected to the interior of the corresponding fixed grooves, and the bottoms of the multiple top plates are abutted against the top of the upper fixed plate.

[0027] The above technical solution achieves lateral fixation of the limiting rod by sliding the moving block and the fixed groove, ensuring that the limiting rod will not move back and forth in the limiting hole, thus enhancing the stability of the wire harness limiting.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the wire harness is connected by a wire terminal fixed inside the outer shell. The grooves on the upper and lower fixing plates cooperate with the limiting holes. During installation, the limiting rod is inserted into the groove and slid to adjust the position. The spring inside the limiting rod pushes the limiting block one into the limiting hole for fixation. The top plate facilitates force application. During disassembly, the top plate is pulled to make the limiting block one disengage from the limiting hole and pull out the limiting rod, realizing the quick installation and disassembly of the wire harness. The structure is stable and the operation is convenient.

[0030] 2. In this utility model, by pushing the moving block, the locking block moves along the locking groove. When the limiting rod reaches the appropriate position, the moving block is lifted to allow the locking block to disengage from the locking groove. Then, the locking block is moved laterally to embed into the fixing groove of the limiting rod. The moving block is then lowered to allow the locking block to engage with the bottom of the fixing groove and fix the limiting rod. When disassembling, the operation is reversed: first, the moving block is lifted to remove the locking block, and then the moving block is pushed to allow the locking block to return to the locking groove. This achieves reliable limiting of the wire harness, enhances structural stability, and ensures the stability and safety of the wire harness connection. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a wire harness terminal sleeve assembly, comprising a housing 1. Multiple wire terminals 3 are fixedly connected inside the housing 1, used to connect and fix the wire harness for electrical connection. Fixing plates 4 are fixedly connected to the upper and lower sides of the front end of the housing 1, serving to connect and fix other components and enhance the stability of the overall structure. Multiple grooves 5 are equidistantly provided on the top of the upper fixing plate 4, providing a sliding track for the limiting rod 7. Multiple limiting holes 6 are equidistantly provided on the rear side of the lower fixing plate 4, cooperating with a limiting block 10 to fix the limiting rod 7. Limiting rods 7 are slidably connected inside the multiple grooves 5, serving to limit the wire harness during installation and ensuring accurate wire harness positioning. Sliding grooves 8 are provided at the bottom of the rear side of each of the multiple limiting rods 7. The groove 8 provides space for the spring 9 and the limiting block 10 to move. The spring 9 is fixedly connected to one side of the interior of the multiple sliding grooves 8. The spring 9 provides elastic force so that the limiting block 10 can be locked into the limiting hole 6 to achieve fixation. The limiting block 10 is fixedly connected to the rear end of the multiple springs 9. The limiting block 10 cooperates with the limiting hole 6 to restrict the movement of the limiting rod 7 and fix the position of the wire harness. The top of the multiple limiting rods 7 is fixedly connected to the top plate 11. The top plate 11 makes it easy for the operator to apply force and operate the limiting rod 7. The top of the outer shell 1 is provided with a limiting mechanism 2. The limiting mechanism 2 further strengthens the limiting of the wire harness and improves the overall stability. The multiple limiting blocks 10 are slidably connected to the interior of the corresponding sliding groove 8. The size of the sliding groove 8 and the limiting block 10 are matched to ensure that the limiting block 10 slides stably in the sliding groove 8 and ensures that the limiting function is reliably realized.

[0040] Specifically, when using this wire harness terminal sleeve assembly, the wire terminal 3 is fixed inside the housing 1 for connecting the wire harness. The fixing plate 4 serves as an important connecting structure. The groove 5 on the top of the upper fixing plate 4 and the limiting hole 6 on the rear side of the lower fixing plate 4 cooperate with each other to achieve a limiting function. When it is necessary to install the wire harness, the limiting rod 7 is inserted into the groove 5. The limiting rod 7 can slide in the groove 5 for easy adjustment of its position. In the sliding groove 8 at the bottom rear side of the limiting rod 7, the spring 9 and the limiting block 10 form an elastic limiting structure. When the spring 9 is in a compressed state, it pushes the limiting block 10. When the limiting rod 7 moves to... When in the appropriate position, the limiting block 10 can be engaged in the limiting hole 6, thereby fixing the position of the limiting rod 7 and thus limiting the wire harness. The top plate 11 is fixed to the top of the limiting rod 7, making it easy for the operator to push or pull the limiting rod 7, thus facilitating the installation and disassembly process. When the wire harness needs to be disassembled, the top plate 11 is pulled upward to overcome the elastic force of the spring 9, causing the limiting block 10 to disengage from the limiting hole 6, and the limiting rod 7 can be pulled out of the groove 5. When the limiting rod 7 moves into place, the limiting block 10 is engaged in the limiting hole 6 under the elastic force of the spring 9, fixing the position of the limiting rod 7.

[0041] Reference Figure 3 and Figure 4 The limiting mechanism 2 includes multiple fixed blocks 201. The bottoms of the multiple fixed blocks 201 are all fixedly connected to the top front side of the outer shell 1, so that the limiting mechanism 2 can accurately engage with the outer shell 1, ensuring the compactness and stability of the overall structure. Each of the multiple fixed blocks 201 has a moving groove 202 on its rear side, providing a channel for the sliding of the moving block 204, allowing the moving block 204 to move smoothly within the fixed block 201. Each of the multiple moving grooves 202 has a locking slot 203 on its top, used for locking and positioning the locking block 205, achieving initial fixation of the moving block 204. The inner top of each of the multiple moving grooves 202 is connected to the corresponding locking slot 203, facilitating the smooth movement of the locking block 205 between the moving groove 202 and the locking slot 203, ensuring the continuity of operation. The interiors of the multiple moving grooves 202 are all slidably connected. There is a movable block 204, which can be adjusted by sliding to achieve the limiting operation of the wire harness. The top and rear sides of multiple movable blocks 204 are fixedly connected to a locking block 205. The locking block 205 cooperates with the locking slot 203 to limit the position of the movable block 204 and prevent it from sliding at will. The lower middle part of the rear side of multiple limiting rods 7 is provided with a fixing slot 206. The fixing slot 206 cooperates with the movable block 204 to further fix the limiting rod 7 and enhance the limiting effect of the wire harness. The front end of multiple movable blocks 204 is slidably connected to the inside of the corresponding fixing slot 206, so that the movable block 204 can be accurately inserted into the fixing slot 206 to achieve effective fixing of the limiting rod 7. The bottom of multiple top plates 11 is attached to the top of the upper fixing plate 4. The top plate 11 plays the role of supporting and stabilizing the limiting rod 7 to ensure the reliability of the limiting operation.

[0042] Specifically, during installation, the moving block 204 is pushed to move the locking block 205 along the slot 203. When the limiting rod 7 moves to the appropriate position, the moving block 204 is lifted upwards, and the locking block 205 is released from the slot 203. The locking block 205 is then moved laterally to embed itself into the fixing slot 206 of the limiting rod 7. Then, the moving block 204 is lowered, and the locking block 205 is locked into the bottom of the fixing slot 206. In this way, the limiting rod 7 is fixed, thereby limiting the wire harness. During disassembly, the operation is reversed. First, the moving block 204 is lifted to remove the locking block 205 from the fixing slot 206. Then, the moving block 204 is pushed to return the locking block 205 to the slot 203, thereby releasing the restriction on the limiting rod 7. The moving block 204 and the fixing slot 206 are slidably connected to achieve lateral fixation of the limiting rod 7, ensuring that the limiting rod 7 will not move back and forth in the limiting hole 6, thus enhancing the stability of the wire harness limitation.

[0043] Reference Figure 1 , Figure 2 and Figure 3 Each of the multiple top plates 11 is fixedly connected to a handle 12, which provides the operator with a convenient part to apply force, making the operation of pulling the limit rod 7 easier and more convenient. Each of the multiple handles 12 has a groove 13 on its front side, which increases the friction between the hand and the handle 12, preventing slippage during operation. A handle 14 is fixedly connected to the rear side of the outer casing 1, which facilitates the overall handling and movement of the wire harness terminal sheath assembly. The outer wall of the handle 14 has a smooth design to avoid scratching the hand during handling and to reduce wear caused by friction with other objects, improving user comfort. The inner left and right sides of the outer casing 1 are provided with sliding grooves 15. 5 provides a guide track for the sliding of the limit rod 7, ensuring that the limit rod 7 remains stable during movement and does not deviate. The left and right sides of the multiple limit rods 7 are fixedly connected to sliders 16. The sliders 16 cooperate with the slide grooves 15 to enhance the stability of the limit rod 7 during sliding and also provide support. The left and right sides of the interior of the multiple limit rods 7 are provided with limit grooves 17. The limit grooves 17 provide the movement space for the second limit block 18, restrict the movement direction of the first limit block 10, and prevent it from falling out. The left and right front sides of the multiple first limit blocks 10 are fixedly connected to the second limit block 18. The second limit block 18 cooperates with the limit grooves 17 to ensure that the first limit block 10 moves stably within the slide groove 8 and ensures that the limit function is realized normally.

[0044] Specifically, the handle 12 on the top of the top plate 11 provides a point of force for the operator to manually pull or push the limit rod 7 to complete the installation and disassembly of the wire harness. The handle 14 on the rear side of the housing 1 facilitates the handling and movement of the entire wire harness terminal sleeve assembly, provides guidance and support for the movement of the limit rod 7, ensures that the limit rod 7 remains stable during sliding, and does not deviate or shake, thus enhancing the stability and reliability of the sliding of the limit rod 7. It also restricts the movement direction of the limit block 10 in the sliding groove 8, prevents the limit block 10 from deviating or coming out under the action of the spring 9, and ensures that the limit block 10 can be accurately engaged in the limit hole 6.

[0045] Working principle: When using this wire harness terminal sleeve assembly, the wire terminal 3 is fixed inside the housing 1 for connecting the wire harness. The fixing plate 4 serves as an important connecting structure. The groove 5 on the top of the upper fixing plate 4 and the limiting hole 6 on the rear side of the lower fixing plate 4 cooperate with each other to achieve the limiting function. When the wire harness needs to be installed, the limiting rod 7 is inserted into the groove 5. The limiting rod 7 can slide in the groove 5 for easy position adjustment. In the sliding groove 8 at the bottom rear side of the limiting rod 7, the spring 9 and the limiting block 10 form an elastic limiting structure. The spring 9 is in a compressed state. Push the limiting block 10. When the limiting rod 7 moves to the appropriate position, the limiting block 10 can be inserted into the limiting hole 6, thereby fixing the position of the limiting rod 7 and thus limiting the wire harness. The top plate 11 is fixed to the top of the limiting rod 7, which makes it easy for the operator to push or pull the limiting rod 7, realizing convenient operation during installation and disassembly. When it is necessary to disassemble the wire harness, pull the top plate 11 upward to overcome the elastic force of the spring 9, so that the limiting block 10 is disengaged from the limiting hole 6, and the limiting rod 7 can be pulled out from the groove 5 to complete the disassembly step.

[0046] During installation, push the movable block 204 to move the locking block 205 along the slot 203. When the limiting rod 7 moves to the appropriate position, lift the movable block 204 upwards, and the locking block 205 will be released from the slot 203. Move the locking block 205 laterally so that it is embedded in the fixing slot 206 of the limiting rod 7. Then lower the movable block 204, and the locking block 205 will be locked into the bottom of the fixing slot 206. In this way, the limiting rod 7 is fixed, thereby limiting the wire harness. During disassembly, simply reverse the operation: first lift the movable block 204, remove the locking block 205 from the fixing slot 206, and then push the movable block 204 to return the locking block 205 to the slot 203, thus releasing the restriction on the limiting rod 7.
