Description

Technical Field

[0001] This utility model relates to the field of heavy-duty connector reinforcement technology, and in particular to a heavy-duty connection assembly with a reinforced housing structure. Background Technology

[0002] In the fields of industrial automation, heavy machinery, rail transportation, and energy equipment, heavy-duty connectors are key components for achieving reliable power and signal transmission. Their structural stability and connection reliability are of paramount importance. These application environments are accompanied by severe mechanical vibration, strong impact, and huge tensile or lateral stress.

[0003] Existing heavy-duty connectors use snap-fit ​​or a few screws for fixing. However, under continuous strong vibration conditions, the simple snap-fit ​​structure will produce slight displacement, causing the connector to disconnect instantly or wear out over time, affecting the stability of signal transmission. While traditional screw fixing methods can provide a certain axial locking force, their ability to resist lateral impact and radial misalignment is relatively weak, resulting in insufficient overall rigidity of the connector. When the connector is hit from the side, the stress will be directly applied to a few locking points, causing structural damage. In addition, the core mating area of ​​these connectors is only protected by a simple shell, with limited protection capabilities. Once subjected to external impact or foreign object intrusion, the internal pin core will be damaged, causing connection failure. Existing technology lacks a systematic solution that can simultaneously provide comprehensive external protection, strong radial restraint, and reliable axial locking, making it difficult to guarantee the long-term reliability of the connection in extremely harsh heavy-duty environments.

[0004] Therefore, this utility model proposes a heavy-duty connecting assembly with a reinforced shell structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of low connection reliability and lack of effective structural protection in the core docking area of ​​existing heavy-duty connection components with reinforced shell structures under strong vibration or impact conditions, this utility model aims to provide a heavy-duty connection component with a reinforced shell structure that has been improved and can effectively solve the above problems.

[0006] This utility model provides a heavy-duty connection assembly with a reinforced shell structure, including: a connector, a mating seat; and a locking protection mechanism and a slot reinforcement mechanism.

[0007] The locking protection mechanism includes a protective shell that detachably covers the connection area between the connector and the mating seat.

[0008] Furthermore, the card slot reinforcement mechanism includes a card sleeve body, which is assembled by radially fitting and clamping the protective shell and the connection area.

[0009] Preferably, the docking head is provided with a positioning block, and the docking seat is provided with a positioning groove for guiding and limiting the positioning block.

[0010] Preferably, the docking head is provided with docking block two and docking block one, and the docking seat is provided with docking block three; the protective shell is provided with docking groove two and docking groove one that are adapted to docking block two, docking block one and docking block three.

[0011] Preferably, the outer walls of the connector and the mating seat are provided with slots for the slot reinforcement mechanism to engage, including slot one, slot two and slot three; the inner wall of the sleeve body is provided with blocks that are adapted to the slots, including block one, block two and block three.

[0012] Preferably, as a specific implementation, when the card sleeve body is fitted into the connection area, the first card block slides into the first card slot, the second card block slides into the second card slot, and the third card block slides into the third card slot.

[0013] Preferably, the card sleeve body is provided with screw hole three, and the card slot reinforcement mechanism further includes positioning screw two, which passes through the screw hole three to lock the card sleeve body.

[0014] Preferably, the main body of the card slot reinforcement mechanism is fitted over the outside of the connection area where the protective shell is installed.

[0015] Preferably, the mating head is provided with a screw hole one, and the mating seat is provided with a screw hole two; the heavy-duty connection assembly with a reinforced shell structure further includes a positioning screw one, which passes through the screw hole one and is threaded into the screw hole two, so as to realize the axial locking of the mating head and the mating seat.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a locking protection mechanism and a slot reinforcement mechanism, forms a composite reinforcement system that first wraps and protects the connection area and then radially tightens it from the outside. This solves the problems of simple structure and insufficient overall connection strength of the connection area in the existing heavy-duty connectors, and achieves the technical effects of stable structure, comprehensive protection and high connection reliability.

[0018] 2. This utility model, by setting a slot reinforcement mechanism, utilizes the card block on the main body of the card sleeve to engage with the slot on the connector and the mating seat, and is locked by the second positioning screw. It applies a strong and uniform clamping force to the connection area from the radial direction, which solves the problem of radial misalignment, loose connection or loosening of the connector in the prior art when it is subjected to vibration or lateral force. It achieves the technical effect of effectively resisting radial impact and vibration and significantly improving connection stability.

[0019] 3. This utility model achieves the final axial rigid locking between the two components by setting a positioning screw that passes through the connector and screws into the mating seat. It works in conjunction with the radial constraint of the slot reinforcement mechanism to solve the problem that the connector may loosen or even separate under heavy load tensile conditions in the prior art. It achieves the technical effect of firm and reliable axial locking, which can withstand huge tensile loads and ensure long-term stable operation under harsh conditions. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a heavy-duty connection assembly with a reinforced shell structure, aiming to solve the problems of insufficient connection reliability and lack of effective protection of existing heavy-duty connectors under complex working conditions due to radial misalignment or axial loosening. Figure 1 As shown, the heavy-duty connection assembly with a reinforced shell structure includes a connector 1 and a mating seat 2 that can mate with the connector 1. Together, they form the basic frame of the connection. To achieve reinforcement and protection, the assembly is also equipped with a locking protection mechanism 3 and a slot reinforcement mechanism 4. The locking protection mechanism 3 can be detachably wrapped around the connection area formed by the connector 1 and the mating seat 2, while the slot reinforcement mechanism 4 is radially fitted and clamps the locking protection mechanism 3 and the connection area.

[0029] To solve the aforementioned technical problems, the technical solution of this embodiment is that the heavy-duty connecting assembly with the reinforced shell structure also has a positioning structure and an axial locking structure. Furthermore, the engaging protection mechanism 3 forms a specific structural fit and connection relationship with the aforementioned mating joint 1 and mating seat 2. Please refer to the following for details. Figure 2 and Figure 3 The structure will be described in detail below:

[0030] The bottom of the connector 1 is provided with a positioning block 37, and the docking seat 2 is provided with a corresponding positioning groove 36. The positioning block 37 is initially fitted and embedded in the positioning groove 36 through the adaptation of shape and size, realizing the initial radial guidance and limitation of the connector 1 and the docking seat 2. At the same time, the connector 1 is provided with a second docking block 35 and a first docking block 32, and the docking seat 2 is provided with a third docking block 38. The protective shell 31 of the locking protection mechanism 3 is provided with a second docking groove 34 and a first docking groove 33. In the assembled state, the second docking groove 34 of the protective shell 31 and the second docking block 38 are connected. 5. The mating groove 33 engages with the mating block 32. At the same time, the groove on the other matching protective shell 31 engages with the mating block 38, so that the protective shell 31 can detachably wrap and protect the upper part of the connector 1 and the lower part of the mating seat 2. In addition, the connector 1 is provided with a screw hole 39, and the mating seat 2 is provided with a screw hole 310. The inner side of the screw hole 310 is machined with a matching internal thread. The assembly also includes a positioning screw 311, which passes through the screw hole 39 and is threaded into the screw hole 310 to form a rigid axial lock.

[0031] Based on the above embodiments, as a preferred implementation method, please refer to... Figure 3 and Figure 4 The card slot reinforcement mechanism 4 includes a card sleeve body 41 and a positioning screw 49. To achieve radial snap-fit, card slots 45, 46, and 47 are provided on the outer walls of the connector 1 and the mating seat 2. Card blocks 42, 43, and 44, which are adapted to the shape and size of the aforementioned card slots, are provided on the inner wall of the card sleeve body 41. The card sleeve body 41 is fitted onto the outside of the connection area where the protective shell 31 is installed. After being fitted, card block 42 engages with card slot 45, card block 43 engages with card slot 46, and card block 44 engages with card slot 47 to achieve initial radial clamping. To achieve final rigid locking, a screw hole 48 is also provided on the card sleeve body 41. The positioning screw 49 passes through the screw hole 48 to lock and fix the structures on both sides of the card sleeve body 41.

[0032] Working principle: When a heavy-duty connection needs to be established, the connector 1 is first brought closer to the docking seat 2 along the axial direction. During this process, the positioning structure of the locking protection mechanism 3 plays a core guiding role. The positioning block 37 on the connector 1 and the positioning groove 36 on the docking seat 2 form a preliminary fit through the adaptation of shape and size. The positioning block 37 is embedded in the positioning groove 36, which restricts the two from being misaligned in the radial direction. This ensures that the connector 1 and the docking seat 2 approach each other along the preset axial trajectory, providing basic positioning constraints for the subsequent locking of the protective sleeve, sleeve connection and screw locking.

[0033] After the initial positioning of the connector 1 and the docking seat 2, the locking protection mechanism 3 is activated to protect and lock the upper part of the connector 1 and the lower part of the docking seat 2. The upper protective shell 31 with the second docking groove 34 is moved to the top of the connector 1. At this time, the second docking block 35 on the connector 1 is locked with the second docking groove 34 of the upper protective shell 31. After the locking block slides into the locking groove, a locking structure is formed, so that the upper protective shell 31 firmly wraps the top of the connector 1. The protective shell 31 with the first docking groove 33 is adjusted so that the first docking groove 33 of the protective shell 31 is locked with the first docking block 32 on the connector 1, further improving the protection range of the connector 1.

[0034] Move another compatible protective shell 31 to the lower part of the docking seat 2, so that the docking block 38 on the docking seat 2 engages with the corresponding slot of the protective shell 31, so that the protective shell 31 wraps around the lower part of the docking seat 2. The lower part of the docking seat 2 is tightly covered by the protective shell 31. At this time, the docking joint 1 and the docking seat 2 are protected by the protective shell 31 through the engaging protection mechanism 3, blocking most of the external interference and ensuring the structural integrity of the core connection area.

[0035] After the locking and protection mechanism 3 completes the overall locking of the protective shell 31 with the connector 1 and the docking seat 2, the slot reinforcement mechanism 4 is activated. The sleeve radially tightens the connection area between the connector 1 and the docking seat 2. The sleeve body 41 is then inserted into the connection area between the connector 1 and the docking seat 2 from the outside. During the insertion process, it is necessary to ensure that the first locking block 42, the second locking block 43, and the third locking block 44 on the sleeve body 41 are respectively connected with the slots 45, 46, and 47 of the docking seat 2, as well as the corresponding slots of the connector 1. The geometric contour of each locking block matches the groove shape of the corresponding slot. After sliding in along the slot guide, the sleeve body 41 is initially radially locked with the docking seat 2 and the connector 1. At this time, the sleeve body 41 tightens the connection part radially, restricting the radial relative displacement of the connector 1 and the docking seat 2, providing circumferential constraint structural support for subsequent locking and reinforcement, and initially improving the connection stability.

[0036] After the initial snap-fit ​​is completed, the main body 41 of the ferrule is locked and reinforced by the second positioning screw 49: the second positioning screw 49 is inserted into the screw hole 48 on the main body 41 of the ferrule, and then the second positioning screw 49 is tightened. As the screw is tightened, the two side structures of the main body 41 of the ferrule are fixed. At this time, the radial force of the slot reinforcement mechanism 4 is the rigid constraint of the screw locking. Under the complex working conditions of heavy load, it can effectively prevent the ferrule from loosening and strengthen the radial fixing effect of the connector 1 and the mating seat 2.

[0037] After the screw connection groove reinforcement mechanism 4 of the connector 1 and the docking seat 2 completes the locking and reinforcement of the ferrule, the axial final locking of the connector 1 and the docking seat 2 is achieved by screw connection. The positioning screw 311 is inserted into the screw hole 39 on the connector 1 and screwed into the screw hole 310 on the docking seat 2. The inner side of the screw hole 310 is machined with an internal thread that matches the positioning screw 311. When the positioning screw 311 is tightened, the connector 1 and the docking seat 2 form a rigid axial lock. Even under heavy load conditions, the connector 1 and the docking seat 2 can ensure the reliability, stability and long service life of the connection.
